Description

ASSEMBLY PE TOOTH IN MULTIPLE PARTS FOR EXCAVAS FIELD OF THE INVENTION The present invention relates generally to equipment that engages the ground, and more specifically, to a multi-part tooth assembly for excaling that includes an excavating tooth and an adapter operatively interconnected one in relation to the other, by means of a retaining bolt structure.

Background of the Invention The excavation equipment used in mining, construction, and in a myriad of other ground engaging operations, typically includes a series of 15 separate ground engaging teeth, mounted in a side-by-side relationship through of a shovel lip. The teeth project forward to engage with, and break, the material to be collected on a shovel. The technique recognized long ago the advantages that can be This can be obtained by connecting the relatively small excavating tooth or excavator with a relatively large adapter or support, which in turn is connected to the excavating blade or equipment. Typically, the adapter or holder includes a base portion configured to join to the front lip of a blade, and a nose portion of free ends. In many applications, the conjunction between the tooth to dig and the adapter involves providing the tooth to dig or dig, a bag or cavity that opens towards the back of the tooth, and that fits over and along a substantial length of the adapter nose-portion. A suitable bolt operatively interconnects the tooth and the adapter in an operative relation one in relation to the other. Normally, and especially in the global economy * Currently, components that comprise a multi-piece tooth assembly that is coupled to the ground, are manufactured and / or manufactured in different parts of the globe. That is, a tooth or point for digging can be manufactured or manufactured in one part of the world, that is, in China, while the adapter or holder for the tooth can be manufactured or manufactured independently in another part of the world, ie , Mexico. It is common that these parts Separated F or components of the tooth assembly for digging are assembled only when the machine or apparatus in which they are to be configured is manufactured and assembled. Accordingly, the parts or components of the multi-piece tooth assembly require liberal tolerances to enable the parts manufactured in different manufacturing facilities of the globe to be adjusted and operated in combination with each other. As will be appreciated by those skilled in the art, when connected to a blade or the like, the tooth assemblies for digging are often subject to highly abrasive conditions, and therefore, experience rapid and considerable wear. Moreover, the high relative forces developed during the operation of the excavating tooth assembly also add to the rapid wear of the component parts of the excavating tooth assembly.

J? Typically, each tooth for digging is provided with a cutting edge extending through a front edge of the tooth, to facilitate penetration and breaking of the soil. The cutting edge of each tooth is oriented to extend transversely of the tooth, and in a relationship generally parallel with the work surface being excavated or scraped. In service, and although specific steps may have been applied to the tooth during its manufacture, the front cut edge of the tooth wears out and becomes dull and to be inefficient quickly in the operation of digging, and therefore, requires replacement. The construction of multiple pieces of a tooth assembly conveniently allows the tooth for digging or excavating the assembly to be replaced in a manner independent of the adapter. Depending on the type of excavation involved, a given adapter can be successively equipped with anything from 5 to 30 replacement teeth to keep the penetrating edges sharp. In the field, the replacement of ^^ Parts of teeth to dig used is common, and some 5 times is a daily experience. As can be seen, during an excavation, digging, or loading operation, extremely high vertical forces are imparted to each excavating tooth assembly associated with the excavating equipment. An adapter or conventional support has a generally flat top and bottom surface, which correspond to the flat surfaces of the tooth to be scraped on which they rest. Under conditions of extreme load, and although they are interconnected through a bolt or similar, the tooth to dig or digging tends to move forward and down in relation to the nose portion of the adapter. The loose fit between the component parts is additionally added to the relative movement between the tooth and the adapter or holder. The • tendency of the tooth to move in relation to the adapter exacerbates the problem of wear, especially in the area of the bag and along the nose portion of the adapter. The existence of dust and dirt between the confronted sliding surfaces on the tooth to dig and the adapter, is added in addition to the deterioration of the component parts of the tooth assembly to dig. Therefore, the critical conjunction between the tooth to dig and the adapter is subject to wear conditions _ accelerated, which can result in a failure of the ^^ tooth bag and / or a premature replacement of the adapter. 5 Although the vertical loads imparted to each tooth assembly during a ground engaging operation are significant, the horizontal or lateral load imparted to the teeth is also of concern. For example, and as will be appreciated, the horizontal loads and forces imparted to a tooth for digging fixed to a saw and coupling equipment with similar soil may be significant. In accordance with the above, each tooth assembly for digging needs to be configured to accommodate both horizontal and vertical loads imparted to it during normal operation. Of course, if the excavating tooth were to break during the operation, the intermixing of a broken tooth component with the rest of the excavated materials can cause significant material handling problems in the subsequent operations, that is, in the crushing operations. If a tooth or tip is lost, the adapter will become damaged quickly, because the nose portion of the adapter is not made to withstand highly abrasive conditions. More so, and especially when it consider shovels or loaders of excavators, the horizontal width of each tooth assembly needs to be controlled, in order to accommodate an adequate number of teeth along a front edge or lip of the excavator or shovel. Securing the excavating tooth or digging the adapter requires a compromise between two opposing demands. On the one hand, the method for securing the tooth to the adapter must be strong enough to maintain the tooth and the adapter in an operative relatiop, regardless of the tremendous shock loads encountered during an excavation operation. However, when tooth replacement is required or desired, the bolt to secure the tooth to the adapter must be easily removable. Frequently, and especially in field conditions, the removal / replacement of the retaining bolt is performed under rather primitive conditions. Normally, the retaining bolt has to be removed with only a hammer and chisel, which makes it difficult to overcome a tight lock coupling. Until now, Known bolt systems to secure an excavating tooth to an adapter have involved inserting a bolt or multiple shorter bolts, either horizontally or vertically through the openings in the tooth and adapter. The vertically oriented bolt systems conveniently provide greater access to the bolt. Although better access is provided to impact the retaining bolt with a hammer, the vertical orientation of the retaining bolt exposes the retaining bolt to rocks and other means being excavated, causing bolt wear, and in some extreme cases , the dislodging of the retaining bolt. Moreover, with the vertical bolt restraint systems, the vertical movements of the excavating equipment tend to work against the bolt system vertically oriented, or causing it to wear, and in some extreme cases, to become dislodged, allowing this so that the tooth and the adapter inadvertently separate during an excavation operation. The systems of horizontal bolts, although allow a secure connection of the tooth to dig and the adapter, also have certain drawbacks associated with them. As will be appreciated, when it is secured through a front edge or lip of the excavator equipment, it is • minimizes lateral or horizontal separation between tooth assemblies for adjacent excavation and / or wear covers. These narrow space limitations make it difficult to horizontally drive a retaining bolt horizontally disposed during the installation and removal of the teeth to dig. In fact, industries are known repaired directed specifically to the problem of driving horizontal retaining bolts in relation to the tooth assembly for digging, and special devices have been proposed to solve the problems inherent to the horizontal bolt systems. Accordingly, there is a need and desire for a tooth assembly to dig that offers better strength characteristics, capable of handling extreme load conditions imparted to the tooth assembly -during the excavation operations, and whose configuration lends itself to a bolt system that eliminates problems and # difficulties associated with the horizontal and vertical bolt systems known so far.

SUMMARY OF THE INVENTION In view of the above, and in accordance with the present invention, a tooth assembly is provided in multiple pieces for excavating, including an adapter, a tooth for digging or excavating, and a bolt structure. • to interconnect the adapter and the tooth in a operational combination one in relation to the other. The tooth and the adapter have an interface or conjunction uniquely configured between them. Moreover, the conjunction between the tooth to dig and the adapter is configured to conveniently orient the structure of the bolt, with in order to avoid the inherent problems with the vertical and horizontal bolt systems described above, while producing other advantages • unknown until now. The adapter for the multi-piece tooth assembly of the present invention has a base portion and a nose portion axially aligned one relative to the other, along a longitudinal center line. The base portion of the adapter is configured to allow attachment of the adapter to the excavator equipment. According to one aspect of the present invention, the nose portion of the adapter has upper and lower surfaces disposed above and below the longitudinal centerline of the adapter, respectively. At least the top surface on the nose portion of the adapter has two sides or facets joined together along a common edge extending longitudinally forward from a rearward end of, and by a distance along, the nose portion. Each side or facet that forms the • upper surface of the adapter, it is configured on the opposite lateral sides of the longitudinal centerline of the adapter. The adapter is further configured to accommodate the bolt structure used to hold in a releasable manner and stop the tooth for digging or digging and the adapter in an operational combination one in relation to the other. In a preferred form of the invention, the lower surface of the nose portion of the adapter has two sides or facets, which in the same manner are joined to one another along a common extending edge. ^^ longitudinally forward from a rear end 5 of, and by a distance along, the nose portion of the adapter. Like those on the upper surface, the sides or facets on the lower surface of the nose portion of the adapter are formed on the opposite lateral sides of the longitudinal axis of the adapter. The digging tooth of the excavating tooth assembly of the present invention has a leading end and a trailing end. The back end of the tooth defines a blind cavity or socket configured to accommodate a larger section of the nose portion of the tooth. adapter inside it. The digging or excavating tooth is further configured to cooperate with the configuration of the adapter, to accommodate the structure of the bolt. The bolt structure to stop the adapter and The tooth for digging in an operative combination, one in relation to the other, can take a myriad of different designs, without harming or departing from the spirit and scope of the present invention. In one form, the retaining bolt preferably has an elongated configuration that allows the bolt to pass through the end through a hole in the adapter, and extend at least partially into the axially aligned holes defined by the tooth for scratch. Alternatively, the bolt structure may include a bolt that extends partially through the holes axially aligned in the tooth to dig, and operatively engages, from its opposite intermediate ends, with an open channel on an outer flange defined in the adapter. In another form, the structure of the bolt can take the form of a stop or displaceable bolt that passes into a recess formed on the adapter, and extends until it becomes releasably associated with a recess in the tooth, maintaining this way to the tooth to dig and the adapter in operative association one in relation to the other. As will be As appreciated by those skilled in the art, the bolt structure further includes some form of mechanism or device for inhibiting inadvertent movement by the ends of the retaining bolt relative to the adapter and the tooth.

• The adapter and the tooth for digging of the assembly of the excavating tooth are preferably formed with supports to stabilize the tooth assembly during an excavation operation. In a preferred form, the brackets for stabilizing the tooth and the adapter each include generally horizontal surfaces and generally verticals provided on the upper and lower surfaces of the adapter, and the corresponding areas of the tooth. In a preferred form of the invention, the two sides forming the upper surface in the nose portion of the adapter, are disposed downward or angled, and have a generally flat configuration to add stability to the conjunction between the tooth and the adapter . Moreover, the two sides of the lower surface in the nose portion of the adapter, preferably are arranged upwards or angled, and in the same way, tend a generally flat configuration, to further add stability to the conjunction between the adapter and the tooth to dig. To complement the design of the tooth, which typically incorporates a generally wedge-shaped profile, the sides or facets of the upper and lower surfaces are tilted downward towards a free end of the nose portion of the adapter, such that they have a convergent angle in relation to the other. To add strength, durability, and rigidity to it, the adapter is preferably formed as a result of a forging operation. A more preferred form of the present invention provides the nose portion of the adapter with a quadrilaterally configured cross section configuration. Unlike the nose portions known hitherto in other adapters, however, the quadrilaterally shaped or generally rectangular shape or configuration of the nose portion of a preferred form of the invention is offset at an angle between about 25 ° and about 65 ° relative to the orientation of the base portion of the adapter. In a more preferred form of the invention, the rectangularly shaped cross section of the nose portion of the adapter is offset by an angle of approximately 45 ° relative to the base portion of the adapter. In an alternative way, the common edges joining the sides of the upper and lower surfaces of the nose portion of the adapter, can be separated by a first distance that is greater than the second distance separating the common edges diametrically opposed and extending longitudinally, which they join the sides of the upper and lower surfaces of the nose portion of the adapter, configured towards one or the other lateral side of the longitudinal centerline of the adapter. This uniquely configured design improves the strength of the nose portion of the adapter, thereby adding to its durability and operational utility. As is typical, the bridge or tooth of the excavating tooth assembly has a generally wedge-shaped lateral profile. The tooth has a border that penetrates the floor, which extends transversely through <; of a front end thereof, to improve the penetration of an earth surface, and which extends generally ? ^^ parallel to a shore or lip of the excavation equipment or shovel - 5 with which it is connected. As mentioned above, the trailing end of the tooth defines a blind cavity that opens toward a posterior end of the tooth, and which allows the nose portion of the adapter to slidably fit into it. Another aspect of the present invention relates to the configuration of the trailing end, and more specifically, to the configuration of the cavity that forms part of the conjunction between the tooth and the adapter. The blind cavity defined by the tooth for digging includes upper and lower surfaces arranged on opposite sides of a longitudinal central line of the tooth. As will be appreciated, the cross-sectional configuration of the cavity defined at the posterior end of the tooth, • complements the cross section configuration of the nose portion of the adapter. In the illustrated embodiment, the upper surface of the tooth cavity is defined by two sides or facets; extending each side or facet at an acute angle ranging between approximately 25 ° and approximately 65 ° in relation with the edge that penetrates the floor of the tooth. Each side that forms the upper surface of the cavity or socket defined by the tooth, is configured on the opposite lateral sides of the longitudinal center line of the tooth, and has a common edge extending between the same ones. In a preferred form of the invention, the lower surface of the tooth cavity in the same manner is defined by two sides or facets; extending each side or facet at an acute angle between about 25 ° and about 65 ° relative to the edge of the tooth penetrating the ground. Each side that forms the lower surface of the cavity or socket, defined by the tooth, is configured on the opposite lateral sides of the longitudinal center line of the tooth, and has a common edge extending between them. The tooth for digging defines further a recess configured to accommodate a retaining bolt structure defining an axis that preferably extends generally normal to one of the sides or facets of the upper surface of the blind cavity defined by the • tooth . In a preferred form of the invention, the two sides that form the upper surface of the blind cavity defined by the tooth, have generally flat configurations. Moreover, and in the modalities thus configured, each side that defines the lower surface of the blind cavity of the tooth, in the same way preferably has a flat configuration. In this preferred design, the blind cavity defined by the tooth has a quadrilaterally shaped cross-sectional configuration along a larger portion therealong. Notably, the quadrilaterally configured, and generally generally rectangular, cross-sectional configuration of the cavity is offset by an angle between about 25 ° and about 65 ° relative to the transverse edge of the tooth which engages with the ground. In a more preferred form of the invention, the tooth for digging is manufactured using a forging process, to improve the strength, rigidity, and weariness thereof in hostile and demanding environments. In one form of the invention, and to accommodate certain types of retaining pin structure described above, a defined hole is provided in the nose portion of the adapter, and holes aligned in the tooth for picking, in addition one in relation to the others, to accommodate the passage through the ends of, and then maintain, an elongate retaining bolt in operative association with the tooth and the adapter. In accordance with another aspect of the invention, the hole defined by the nose portion of the adapter is disposed along an axis intersecting the opposite side sides of the upper and lower surfaces of the nose portion of the adapter. According to yet another aspect of the present invention, the recess defined by the tooth for digging, to accommodate at least a portion of the structure of the tooth. ^^ retaining bolt inside it, defines an axis 5 arranged at an angle between approximately 25 ° and 65 ° in relation to the front cutting edge of the tooth. With the different embodiments of the invention, the axis of the structure of the retaining bolt preferably extends normally to one side or facet of the upper surface ß of the nose portion of the adapter or blind cavity of the tooth, respectively. This inclined or edge orientation of the retaining bolt structure offers several advantages hitherto unknown. First, the inclined orientation of the bolt structure offers advantages ergonomic during the repair and replacement of the tooth to dig, and especially because it involves the insertion and removal of the structure of the retaining bolt. These ergonomic advantages are even more apparent, depending on the arrangement of the shovel or implement where you go repair and / or replace the tooth to dig. Moreover, the inclined orientation of the retaining bolt structure produces a visual indication of the proper orientation of the tooth to dig in relation to the adapter during the assembly of the pricking tooth. As will be appreciated by Those skilled in the art, certain teeth for digging or digging are purposely designed with a specific angle of attack in relation to the blade or implement coupling with the ground on which they are mounted. With ^^ Often, the tooth for digging is incorrectly mounted 5 on the blade, thus losing the benefits for which it was specifically designed. With the present invention, the inclined orientation of the bolt structure provides the proper orientation of the tooth and the adapter during assembly, thus allowing the user to take advantage H) completely the benefits specifically designed on the tooth to dig. As will be appreciated from an understanding of the present invention, and as described in greater detail below, the angular orientation of the components of the tooth for digging and the adapter, forming the conjunction between them, have been modified in a meaningful way from the designs of assemblies of teeth for anterior digging, to purposefully distinguish this design from the prior art, while offering concurrently a higher resistance to the conjunction between them. The angled arrangement of the facets that form the upper surface of the nose portion of the adapter and the blind cavity in the tooth, conveniently promotes a self-centering effect for loose fit between the tooth and the tooth. adapter. Additionally, the angled arrangement of the facets forming the upper surface on the nose portion of the adapter, and the upper surface of the cavity in the tooth, produces an increase in surface area contact (comparing to cross-sectional areas 5 similarly. configured oriented or arranged in line with the base portion of the adapter and the front edge of the tooth) at the conjunction between the component parts of the tooth assembly, thus adding to the ability of the parts to distribute the loads imparted. the same during the operations of coupling with the ground over a wider area. The angled modification of the component parts that form the conjunction between the tooth and the adapter, also conveniently disposes the bolt structure retention in a different orientation from a strict and limiting vertical or horizontal orientation. Instead of conforming to the previous configurations, the angular offset relationship offered to the component parts of the • conjunction of the present invention, allows the bolt of The retention in the same manner becomes offset by an angle in relation to the horizontal range between approximately 25 ° and approximately 65 ° in relation to a horizontal plane, thus producing the advantages mentioned above, together with others. That is, with guidance The angular structure of the bolt structure, the materials that are being excavated and the vertical movements or digging forces of the excavating equipment, normally imparted to the vertically oriented bolt structures, will have a significantly lesser adverse effect on the structure 5 of the retaining bolt of the present invention, during excavation operations. Another advantage to be appreciated from the new design disclosed by the present invention relates to the greater space it provides for substantially unobstructed access to the pin? retention, compared to the designs of teeth for digging or digging, wherein the retention pin is arranged in a generally horizontal orientation. These and numerous other objects, objects, and advantages of the present invention will become readily apparent from the following detailed description, drawings, and appended claims.

Detailed Description of the Present Invention Although the present invention is susceptible to incorporation in multiple ways, various preferred embodiments of the present invention are shown in the drawings, and will be described hereinafter, with the understanding that the present disclosure is should consider to stipulate the exemplifications of the invention, which are not intended to limit the invention to the specific embodiments illustrated and described. Referring now to the drawings, in which like reference numerals indicate like parts throughout the different views, in Figure 1 there is illustrated an excavator tooth assembly 10 incorporating different principles and different aspects of the present invention. As shown, the excavating tooth assembly 10 is of a multi-piece construction, and includes an adapter or support 12, and an excavating tooth 14 halted in one position or orientation relative to the other. In the embodiment illustrated in Figure 1, a retaining bolt apparatus 16 releasably interconnects and holds the adapter 12 and the excavating tooth 14 in an operative combination one in relation to the other. Although only one excavating tooth assembly is shown in Figure 1 as attached to excavating equipment 18, such as a front lip 20 of a digging shovel or the like, it will be understood by those skilled in the art that, in a typical piece of equipment Excavator, a plurality of laterally spaced apart tooth assemblies, substantially identical to the tooth assembly 10, would extend forwardly from the blade lip 20, in an orientation engagement with the ground. Moreover, and as will be appreciated by those skilled in the art, the bucket, shovel, or other excavator type part to which the excavating tooth assembly 10 is connected, moves both vertically and horizontally during an excavation operation. As illustrated in Figures 1 to 4, the adapter or holder 12 has an elongated free end configuration defining a longitudinal center line 22. The adapter or holder 12 includes a conventional base portion 24, and an axially aligned nose portion. 26 extending forward from the base portion 24, in a cantilevered manner, from the front edge or lip 20 of the soil excavator or shovel 18. The base portion 24 of the adapter 12 is configured to be attached to the coupling apparatus with the floor 18. In some larger forms of equipment, the base portion 24 of the adapter 12 is configured to be releasably secured, such as by a conventional wedge lock mechanism (not shown), to the front lip 20 of the immersion bucket or shovel 18 of the earth digging apparatus. As is typical, the excavating tooth 14 is fitted at the ends along and around the nose portion 26 of the adapter 12. In a preferred form, the adapter 12 is formed as a result of a forging operation, thereby adding strength and rigidity to the adapter 12. As shown in Figures 3, 4, and 5, the nose portion 25 of the adapter 12 has a forwardly lowered I 5 configuration including angularly converging upper and lower surfaces, the outer surfaces 30 and 40, respectively. The upper and lower surfaces 30 and 40, respectively, are arranged generally above and below, respectively, of the center line longitudinally of the adapter 12. In a preferred form of the invention, and as shown in Figures 4, 5, and 7, the outer upper and lower surfaces 30, 40, respectively, of the adapter 12, are each provided with a recessed area 32, 42, respectively, configured towards a terminal end region 33 of the adapter 12. Preferably, the recessed areas 32, 42 are likewise arranged on the surfaces 30, 40, and in relation to the longitudinal centerline 22 of the adapter 12. Each area • recessed 32, 42 defines a stabilizing surface or floor on the surfaces 30, 40 of the adapter 12. Each floor 32, 42 protrudes inwardly from the respective inclined surface I 30, 40 on the adapter 12, to define a generally flat or horizontal surface I 34, 44 extending generally parallel to the longitudinal central line 25 of the adapter 12. As will be appreciated, a previously determined vertical distance can be measured between the generally horizontal planes or surfaces 34, 44 on the upper and lower surfaces 30, 40 of the • adapter 12. Moreover, each floor 32, 42 includes a generally vertical stabilizing wall 35, 45, respectively. As will be described later, the floors 32, 42 on the upper and lower surfaces 30 and 32, respectively, of the adapter 12, provide a greater load distribution to absorb the extreme vertical loads commonly.

JO imparted to the tooth assembly during an excavation operation, while the vertical stabilizing walls 35, 45 on each stabilizing floor 32, 42, respectively, provide additional vertical support surfaces, to assist in the absorption of the loads extreme horizontals, which in the same way are commonly imparted to the tooth assembly during an excavation operation. One of the salient features of the present invention relates to a unique configuration of the nose portion 26 of the adapter 12. As shown in Figures 4, 6, and 7, the upper surface 30 of the adapter 12 has two sides or facets disposed downwards 36 and 37, attached to one another along the a common top edge 38, and extending forward along the adapter 12 from the base portion 24. As shown, * the sides or facets 36, 37 forming the upper surface 30 of the adapter 12, are configured on opposite side sides of the longitudinal centerline 22 of the adapter 12. The common top edge 38 joining the two sides 36, 37, 5 extends for a longer length of the adapter 12, and is disposed in a generally central manner along the longitudinal center line 22 thereof. In a preferred form of the invention, the sides 36, 37 forming the upper surface 30 of the adapter 12, are inclined longitudinally downward toward the free end of the nose portion 26 of the adapter 12. In a preferred form of the invention , the downwardly disposed sides 36, 37, which form the upper surface 30 of the adapter 12, each have a generally planar configuration. In this form of the invention, the sides 36, 37 forming the upper surface of the adapter 12 are each inclined at an angle of approximately 45 ° relative to a horizontal plane. In a preferred form of the invention, and as shown better in Figure 6, the lower surface 40 of the adapter 12 has a complementary configuration in relation to the upper surface 30. That is, the lower surface 40 of the adapter 12 has two sides or facets disposed upwards 46 and 47 joined one with the other 5 along a common bottom edge 48, and extending forwardly along the adapter 12 from the base portion 24. As shown, the sides or I facets 46, 47 forming the lower surface 40 of the adapter 12, are formed on the opposite lateral sides of the longitudinal centerline 22 of the adapter 12. The common bottom edge 48 that joins the two sides 46, 47, extends along a major portion of the adapter 12, and is disposed in a generally central manner along the longitudinal centerline 22 thereof. In a preferred form of the invention, the sides 46, 47 of the lower surface 40, are inclined longitudinally downward toward the free end of the nose portion 26 of the adapter 12. In a preferred form of the invention, the sides 46 47, which form the lower surface 40 of the adapter 12, each have a generally planar configuration. In this form of the invention, the sides 46, 47 that form the upper surface of the adapter 12, each tilt at an angle of approximately 45 ° relative to a horizontal plane. In the embodiment of the invention wherein the sides 36, 37 forming the upper surface 30, and the sides 46, 47 forming the lower surface 40 of the adapter 12, are configured with generally flat configurations, as shown in Figure 6, the nose portion 26 of the adapter 12 it is provided with a cross-sectional configuration of the generally rectangular type for a greater longitudinal distance along the same. Because the sides 36, 37 and 46, 47 of the upper and lower surfaces 30 and 40, respectively, converge towards the terminal end 5 of the adapter 12, the rectangular cross-sectional configuration of the nose portion 26 of the adapter 12 it increases as a function of the distance measured backwards from its free end end 33. In this embodiment of the invention, the angularly disposed sides JO 36 and 46, forming the upper and lower surfaces 30 and 40, respectively, which are arranged towards one side of the longitudinal center line 22 of the adapter 12, in the same manner they are joined to one another along a common lateral edge 39 extending longitudinally forward from the base portion 24 of the adapter 12. In a similar manner, with the embodiment of the invention illustrated in Figure 6, the angularly disposed sides 37 and 47 of the upper and lower surfaces 30. • and 40, respectively, configured on an opposite side of the longitudinal axis 22 of the adapter 12, are joined to one another along a common lateral edge 49, extending longitudinally forward from the base portion 24 of the adapter 12. In the embodiment of the invention illustrated in FIG.

Figure 6, a section along the major portion of the nose portion 26 of the adapter 12, is offset by an angle of approximately 45 ° relative to the base portion 24 of the adapter 12. As such, the measurable vertical distance VD to through the adapter 12, and between the upper and lower common edges 5 and 38 on the upper and lower surfaces 30 and 40, respectively, is significantly greater than the measurable distance through either of the two opposite sides on the surfaces upper and lower 30, 40, respectively, of the adapter 12. In a similar manner, the horizontal HD distance measurable through the adapter 12, and between the common lateral edges 39 and 49 on the upper and lower surfaces 30 and 40, respectively , is significantly greater than the measurable distance through any of the two opposite sides 15 on the upper and lower surfaces 30 and 40, respectively, of the adapter 12.: - The nose portion 26 of the adapter 12 further defines a recess or openings 50 for accommodating the apparatus of ^ pin retention 16. In the embodiment of the invention illustrated in Figures 1 to 7, the recess or hole 50 extends through the adapter 12, and has opposite ends open. As illustrated in Figure 6, the hole or recess 50 is disposed along an axis 52 intersetting opposite sides 36, 47 of the upper and lower surfaces and 40, respectively, arranged on opposite lateral sides of the longitudinal axis of the adapter 12. In the illustrated embodiment, the axis 52 of the recess or hole 50, is disposed at an angle of approximately 45 ° relative to • a horizontal plane. In a more preferred way! of the invention, and to facilitate the manufacture of the adapter by 12, the axis 52 of the recess or hole 50 extends generally I normal to at least one of the sides forming the upper and lower surfaces 30, 40 of the adapter 12. As will be appreciated by those skilled in the art, hole 50 J) will be dimensioned and configured to accommodate the elongate fastener 16, which serves to releasably fasten the adapter 12, and the excavating tooth 14, in an operative combination one in relation to the other. When the multiple excavator tooth is assembled , the digging tooth 14 is configured to be accommodated at the ends along and around a section along the nose portion 26 of the adapter 12. As shown in Figures 1, 2, 8, and 9, the excavating tooth 14 has an elongated wedge type configuration that defines a line in the center 54 with a side cut or edge penetrating the ground 56, which extends transversely through a front end portion 57, and provided with a hollow rear mounting oar 58. When assembled in the Adapter 12, cutting edge or penetrating the ground 56, it extends generally horizontally, and therefore, generally parallel with the edge or lip 20 (Figure 1) of the excavating equipment with which it is operatively connected. As I will be appreciated by those skilled in the art, the hollow mounting end portion 58 allows the tooth 14 to be fitted at the ends on the adapter 12. In a preferred form of the invention, the tooth 14 is formed as a result of a forging operation, and therefore, its strength and rigidity is improved. As shown, the tooth 14 includes the upper and lower outer surfaces 60 and 62, respectively, which extend rearwardly from the leading cut edge 56, and extend toward the rear end 59 of the tooth 14. As the surfaces 60 , 62 extend backward from the edge 56, they diverge angularly away from each other. As shown in Figures 8, 9, 11, and 12, the upper outer surface 60 of the tooth 14 is configured with a specially configured recess 64 extending backward from the side edge 56 (Figure 1), to inhibit the blunting of tooth 14 as a result of its wear. As shown in Figure 13, the cross-sectional configuration of the tooth 14, and its upper surface 60,! they change significantly as a function of the distance measured backwards from its cutting edge (Figure 1). As is conventional in multi-piece tooth assemblies of the type under consideration, and as shown in Figure 10, the back portion 58 of the tooth 14 defines a blind cavity or socket 68 that opens toward the rear end of the tooth 14. In a preferred form i of the invention, and as shown in Figure 9, the edge of the cavity 68 that opens toward the rear end 58, has an inwardly directed radius 69, which extends around it, to facilitate and guide the insertion by the ends of the nose portion 26 of the adapter 12, 'in a coupling conjunction or adjustment relationship with the 'tooth "14. As illustrated in Figures 9 and 10, the cavity 68 defined by the tooth 14 includes the upper and lower internal surfaces I and 70, respectively, extending forwardly from the open rear end of the cavity 68. , towards the front edge 56 of tooth 14, and converge angularly towards each other, substantially at the same angle as the surfaces are disposed • upper and lower 30 and 40, respectively, on the nose portion 26 of the adapter 12. The upper and lower internal surfaces I, 80 terminate in an end plate 67. The upper and lower surfaces 70 and 80, respectively, they are disposed generally above and, respectively below, the longitudinal center line 54 of the tooth 14. In a preferred form of the invention, the upper and lower internal surfaces 70 and 80, respectively, defined by the cavity or baseball. 68 of tooth 14, also include a pair of stabilizing floors 72 • and 82, respectively, configured towards, and extending backwardly from, the terminal end wall 67 of the cavity 68. The stabilizing floors 72, 82 are arranged and configured to engage with the floors 32, 42, respectively, on the nose portion 26, when the adapter 12 and the tooth 14 are configured in a combination operational one in relation to the other. As illustrated in Figures 9, 10, 14, and 15, each stabilizing floor 72, 82 protrudes inwardly from the upper and lower surfaces 70, 80, respectively, toward the center line 54 of the tooth 14, to define generally flat or horizontal surfaces 74, 84 extending generally parallel to the centerline 54 of the tooth 14. As will be appreciated, a previously determined vertical distance can be measured between the flat or generally horizontal surfaces 74, 84, on the surfaces upper and lower 70, 80, respectively, of the cavity 68 defined by the tooth 14. Moreover, each stabilizing floor 72, 82 includes a generally vertical stabilizing wall 75, 85, respectively. As will be appreciated from an understanding of This aspect of the present invention, the floors 72, 82 of the. tooth 14, are combined with the floors 32, 42 of the nose portion 26 of the adapter 12, to absorb and distribute the extreme vertical loads commonly imparted to the tooth assembly 10 during an excavation operation. Moreover, the stabilizing walls 75, 85 of the upper and lower surfaces 70, 80, respectively, of the cavity 68 defined by the tooth 14, are operatively combined with the stabilizing walls 35, 45 (FIG. 5) of the adapter 12. , to provide additional support surfaces, to assist JO in the distribution and absorption of extreme horizontal loads commonly imparted to the assembly of tooth 10 during normal excavation operations. Another outstanding feature of the present invention relates to a unique configuration of the cavity 68 defined by the tooth 14. As shown in Figure 10, the upper surface 70 defining a portion of the cavity 68, has two sides disposed downwardly 76 and 77 attached to one another along a shore higher • common 78, and extending forward from the end open from the cavity 68. As shown, the sides 1 76, 77 defining the upper surface 70 of the cavity 68, are configured on opposite side sides of the longitudinal center line 54 of the tooth 14. The common top edge 78 which joins the two sides 76, 77 of the surface upper 70 of the cavity 68, extends for a greater length of the cavity 68, and is generally disposed central relative to the longitudinal center line 54 of the tooth 14. In a preferred form of the invention, the sides 76 and 77 which they define the upper surface 70 of the cavity, they are inclined longitudinally downwards towards the terminal wall 67 of the cavity 68. In a preferred form of the present invention, the sides 76, 77 forming the upper surface 70 of the cavity 68, defined by tooth 14, each has a generally flat configuration. In this form of the invention, the sides 76, 77 forming the upper surface 70 of the cavity 68, are each inclined at an angle of approximately 45 ° relative to the front cutting edge 56 of the tooth 14.. In the embodiment of the invention illustrated in Figure 10, the lower surface 80 forms part of the cavity 68 as a complementary configuration in relation to the upper surface 70 of the cavity 68 defined by the tooth 14. That is, the lower surface 80 that forms the cavity 68, has two sides arranged upwards 86 and 87, joined together with one another along a common lower edge 88 extending forwardly from the open end of the cavity 68 defined by the tooth 14. As shown, the sides 86, 87 which forming the lower surface 80 of the cavity 68, they are configured on the opposite lateral sides of the longitudinal center line 54 of the tooth 14.

The common lower edge 88 joining the sides 86 and 8.7 of the cavity 68, extends over a greater length of the cavity, and is generally centrally disposed in relation to the longitudinal centerline 54 of the tooth 14. In a preferred form of the present invention, the sides 86, 87 forming the lower surface 80 of the cavity 68 defined by the tooth 14, each have a generally flat configuration. In this form of the invention, the sides 86, 87 that form the upper surface 80 of the cavity 68, are each inclined at an angle of approximately 45 ° relative to the leading cut edge 56 of the tooth 14. In the embodiment of the invention wherein the sides 76, 77 forming the upper surface 70 of the cavity 68, and the sides 86, 87 forming the lower surface 80 of the cavity 68, are configured with generally planar surfaces, as shown in FIG. Figure 10, the cavity 68 is provided with a generally rectangular cross-sectional configuration along a portion of greater length thereof. Because the sides 76, 77 of the upper surface 70, and the sides 86, 87 that form the lower surface 80 of the cavity 68, are inclined one toward the end wall 67, the cross-sectional configuration of the cavity 68 it is reduced in its area, measured \ forward from its open rear end 58. Moreover, and as shown in that embodiment of the invention illustrated in Figure 10, the cavity 68 is offset in relation to the cutting edge or front penetrant, at an angle of approximately 45 °. In the embodiment of the invention illustrated in Figure 10, the angularly disposed sides 76 and > 86, which partially form the upper and lower surfaces 70 and 80, respectively, of the cavity 68, and which are disposed JO to one side of the longitudinal center line 54 of the tooth 14, in the same way they are joined with each other along a common lateral edge 79 extending longitudinally forwardly from the open end of the cavity 68 defined by the tooth 14. In a similar manner, with the embodiment illustrated in Figure 10, the angularly disposed sides 77 and 87, which partially form the surfaces and bottom 70 and 80, respectively, of the cavity 68, which are disposed towards an opposite side of the center line • longitudinal 54 of the tooth 14, are joined to one another along a common lateral edge 89 extending longitudinally forward from the open end of the cavity 68 defined by the tooth 14. To coact with the adapter 12, the digging or digging tooth 14 is further recessed to accommodate a portion along the apparatus of the retaining pin 16. In the embodiment illustrated in Figures 8, 9, 16, and 17, the recessed tooth 14 defines a pair of holes or I axially aligned openings 90 and 92. As illustrated in • Figure 16, the holes 90, 92 are aligned about an axis 94 intersecting the diametrically opposite sides 76 and 87 of the upper and lower surfaces 70 and 80, and passing through the cavity 68 defined by the tooth 14 J In the illustrated form of the invention, the shaft 94 defined by the holes 90, 92 of the tooth 14, is arranged in an argon of about 45 ° in relation to the edge that engages or penetrates the floor 56 of the tooth 14. The holes or openings 90, 92 of the tooth 14 are configured to accommodate a passage through the ends of the pin or fastener holding device 16 therethrough, allowing this so that the adapter 12 and the tooth 14 are interconnected in a releasable manner in an operative relation one in relation to the other. As will be appreciated by, and knob is known by, those skilled in the art, the relationship of • forward and backward of the holes 90, 92 of tooth 14 and the hole 50 in the nose portion 26 of the adapter 12, are configured in such a way that the fastener 16 is held in a secured relationship in relation to the adapter 12 and the tooth 14, to avoid its inadvertent displacement by the ends. 25 The retaining bolt structure or apparatus 16 *. to interconnect in a releasable manner and maintain the adapter 12 and the tooth 14 in an operative combination one in relation to the other, can take a myriad of different forms, without moving away or departing from the spirit and scope of the present invention. In one form, the retaining bolt structure 16 may be of the type disclosed in the co-assigned United States of America Patent Number 5,765,301 issued June 16, 1998, the full disclosure of which is incorporated into the JO present as reference. Suffice it to say, in the embodiment illustrated in Figures 16 and 17, that the retaining pin apparatus 16 passes through the ends through the hole 50 defined in the nose portion 26 of the adapter 12, and extends, at least partially, by inwards towards each of the holes or openings 90, 92 defined by the tooth 14, thus securing the adapter 12 and the tooth 14 in an operative combination one in relation to the other. Bolt structure • retention 16 illustrated in Figures 16 and 17 includes a elongated hollow rigid shirt 95 accommodated within the hole 50 of the nose portion 26 of the adapter 12, and an elongate pin 96 snugly fit, and yet in a slidable manner, in, and extending axially beyond, the opposite ends of the shirt 94, to be coupled with the aligned holes or openings 90, 92 of the tooth 14, * thereby interconnecting in a releasable manner, and keeping the adapter 12 and the tooth 14, in an operative combination one in relation to the other. Another embodiment of a retaining bolt structure or fastener 16 for stopping and maintaining the adapter 12 and the tooth in a combination operative one in relation to the other, is illustrated in Figure 18. This alternative form of the bolt structure of retention is generally designated by reference numeral 116. The elements of this alternative form of fastener that are • identical or functionally analogous to the components of the retaining pin or fastener structure 16 discussed above, are designated by reference numerals identical to those previously used, with the exception that this embodiment of the fastener 116 uses reference numerals of the series of one hundred. In this form, the fastener 116 is of a conventional design, and includes an elongated pin assembly! 194 that • passes through, and extends axially beyond, the hole 50 of the nose portion 26 of the adapter 12. As is known in the art, the bolt assembly 194 typically includes a pair of bolt halves 195 and 197, which are bonded and otherwise walled to an elastomeric member. Elastic 196 between them. The halves of Bolt 195 and 197 are appropriately configured along their lengths, to normally maintain the bolt assembly 194 against end displacement - during an excavation operation. • Figure 19 illustrates yet another embodiment 5 of a fastener for stopping and holding the adapter 12 and the tooth in a combination operative one in relation to the other. This alternative form of fastener is generally designated by reference numeral 216. The elements of this alternative form of fastener which are identical or JO functionally analogous to the components of the fastener 16 discussed above, are designated by reference numerals identical to those previously used, with the exception that this fastener embodiment 16 uses reference numerals in the series of two hundred. In this form, the fastener 216 is of a conventional design, and includes an elongated pin 294 that passes through, and extends at the ends beyond, the hole 50 defined in the nose portion 26 of the adapter 12. Notably , opposite free ends of pin 294 pass at least partially through, and engage with, the perimeter of the axially aligned holes or openings 90, 92 defined by the tooth 14. In this form, the fastener 216 further includes an elastic snap ring 298, preferably carried within a properly configured recess 299, defined by the nose portion 26 of the adapter 12, preferably towards the lower end of, and in a generally concentric relation in relation to, the hole 50. As will be appreciated by those skilled in the art., when the elongated bolt 294 is forced through it, the ring 298 will expand radially when the bolt 294 is forced axially therethrough. After a portion extends along the retaining bolt 294 through the ring 298, an annular groove 296 of the bolt 294 again allows the contraction of the ring 298 around the bolt and inside the groove 296, thus inhibiting normally the movement by the ends of the bolt 294 in relation to the adapter 12 and the tooth 14. Still another alternative form of the retaining bolt structure for stopping and releasably holding the adapter and the tooth of the tooth assembly in multiple pieces in an operative combination one in relation to the other, is illustrated in Fiqura 20. This alternative form of retaining bolt structure or fastener, is generally designated by reference numeral 316. The elements of this alternative form of fastener that are identical or functionally analogous to the components of the fastener 16 discussed above, are designated by reference numerals identical to those previously used, with the exception that this type of fastener 316 uses reference numerals in the series of three hundred. In this form, the retaining bolt structure • 316 is of a conventional design, and includes an elongate bolt 394 which transversely passes through, and in operative engagement with, a raised flange or upper edge 38 on the upper surface 30 of the nose portion 26 of the adapter 12. In This form of the invention, the excavating tooth 14 is provided with a pair of axially aligned holes or openings 390 and 392, arranged on # the opposite sides of its upper surface 60. Moreover, in this form of the invention, and as shown in Figure 21, the upper edge 38 on the nose portion 26 of the adapter 12, is provided with a channel or superior recess open transversely extending 350. Notably, the recess or channel 350 defines an axis 351 extending transversely across, and generally normal to, the longitudinal axis 322 of the adapter 12. As shown, the • opposite ends of channel 350 open sideways opposite 36, 37 of the upper surface 30, and on the opposite lateral sides of the center line of the adapter. As will be appreciated, the channel 350 is positioned axially along the length of the nose portion 26 of the adapter 12, to coact with the axially aligned openings 390, 392 (FIG. 20) of the tooth 14, to stop the die and the adapter in a releasable combination relative to each other after the retaining bolt structure 316 is inserted through each. As will be appreciated, both the axially aligned holes 390, 392 of the tooth 14, and the channel 350 of the adapter 12, are sized to comfortably accommodate the bolt 394 of the retaining bolt structure 316. In a manner known in the art, the fastening bolt 394 preferably has an elongated slotted configuration, with a natural spring force tending to force the bolt 394 to naturally expand radially outward, while allowing radial contraction of the bolt 394, to allow it to be adjusted in a manner slidable through the holes 390, 392 and the channel 350. After the tooth is assembled in the adapter, the holes 390, 392 are aligned with the channel 350, thereby allowing the retaining bolt 394 to pass through. its ends through them. As will be appreciated, after the bolt 394 is passed through them, a portion along the bolt 394 engages the channel 350, thereby inhibiting movement at the ends of the tooth relative to the adapter. In this embodiment of the invention, the channel 350 extends only through a limited area of the adapter 12, thereby adding strength to the nose portion 26 of the adapter 12.

In Figure 22 there is illustrated another alternative form of retaining bolt structure, for releasably stopping and holding the adapter and tooth • tooth assembly in multiple pieces, in a combination 5 operative one in relation to the other. This alternative form of retaining bolt or fastener structure is generally designated by reference numeral 416. The elements of this alternative form of retaining bolt structure that are identical or functionally analogous to the component parts of the bolt structure of Retention 16 discussed above, are designated by reference numerals identical to those previously used, except that this embodiment of the fastener 416 uses reference numerals in the series of four hundred. 15 In this form, the retaining bolt structure 416 includes a pole clip 494 that passes through an opening 490 defined on one side of the digging tooth or excavator 14, and accommodated within a blind recess or opening 450 defined on one side 436 of the upper surface 430 of the adapter 12. The pole holder 494 includes a pair of halves 495 and 497 | elastically joined to one another by an elastomeric member 499, which is bonded to the confronting surfaces of the bolt halves 495 and 497. In one form Preferred, bolt halves 495 and 497 are disposed in a forward and backward relationship relative to each other; such that, when assembling the excava tooth assembly into multiple pieces, the bolt structure 416 serves to force the tooth 14 lengthwise over the nose portion 26 of the adapter 12. As shown in Figure 23, the blind recess 450 is configured to accommodate the free end of the post clip 494. As illustrated, the blind recess or opening 450 opens to the side 436 of the top surface 430 of the adapter 12, and is disposed along the an axis 452¡ which extends generally normal to the generally flat side 436 of the upper surface 430 of the adapter 12. As will be appreciated, the recess 450 is axially disposed at a predetermined ratio relative to the aperture 490 of the tooth 12, then that the components of the tooth assembly are connected in multiple pieces with one another. After the retaining bolt structure 416 passes through the opening 490 of the tooth 12, a portion along the retaining bolt structure 416 fits into the recess 450, thereby inhibi movement by the teeth. ends of tooth 12 and adapter 14 one in relation to the other. Moreover, and because with this embodiment the recess 450 extends only partially through a limited area of the adapter 12, the nose portion 26 of the adapter 12 is provided with extra strength and rigidity. In Figure 24 there is still illustrated another alternative form of retaining bolt structure for stopping in a releasable manner and maintaining the adapter and | tooth of the tooth assembly in multiple pieces, in an operational combination one in relation to the other. The alternative form of the retaining bolt or fastener structure is generally designated by reference numeral 516. The elements of this alternative form of retaining bolt structure that are identical or functionally analogous to the components of the bolt structure of Retention 16 discussed above, I are designated by reference numerals identical to those previously used, with the exception that this embodiment of the fastener 516 uses reference numerals in the series of five hundred. In this form, the retaining bolt structure 516 is substantially similar to that disclosed in U.S. Patent No. 4,611,418, issued September 16, 1986, the entire disclosure of which is incorporated herein by reference. . Suffice it to say, and as shown in Figures 24 and 25, that the retaining bolt structure 516 includes an elastically forced stop 594. As illustrated in Figure 24, the arrest 594 is accommodated within a recess or opening 550. defined on the nose portion i 26 of the adapter 12. A recess or aperture 590 is configured in a cooperative manner on the tooth to scrape 12, for • accommoda the free end of the stop 594. As shown, the hole or recess 550 for accommoda the retainer bolt structure 516, defines an axis 552 disposed generally normal to the flat configuration of one side on one of the surfaces or lower of the nose portion 26 of the adapter. As shown in Figure 24, one can configure a plurality of detentions in a cooperative relationship in relation to one another. When a plurality of retaining bolt structures 516 are configured, similar to those disclosed in the Figures , 24 and 25, in a cooperative relationship with one another in order to releasably hold the tooth and the adapter in an operative combination one in relation to the other, the axial arrangement of the arrests 594 can • require an axial separation along the length of the nose portion 26 of the adapter 12. As will be appreciated by those skilled in the art, a curved surface on the back edge of the blind cavity 68 defined by the tooth 14 will facilitate compression of the elastic fastener 594 during assembly of the tooth and the adapter. >; Figure 26 illustrates another form for the adapter • »12, which incorporates the features of the present invention. This alternative form of adapter is generally designated by the reference numeral 612. The elements of this alternative form of the adapter that are identical or functionally analogous to the components discussed above with respect to the adapter 12, are designated by reference numerals identical to those used. previously, with the exception that this modality uses reference numerals in the series of six hundred. ?? In this embodiment of the invention, the adapter 612 includes a base portion 624 and a nose portion 626 in an axially aligned relation one relative to the other, and defines a center line 622. Like the adapter 12, the adapter 612 of preference is manufactured in an operation of forging, to extend the durability, and therefore, life of the adapter 612. As discussed above, the nose portion 626 of the adapter 612 has an elongated axially thinned configuration, with surfaces • upper and lower 630 and 640, respectively, which tilt and converge towards a free end of the nose portion 626. As shown, the upper and lower surfaces 630 and 640, respectively, are disposed above and below, respectively, of the longitudinal center line 622. The top surface 630 includes two sides or facets 636 and 637, which extend forward from the base portion 624 of the adapter 612, and are disposed on the opposite side sides of the longitudinal centerline 622, and intersect or fuse with one another , along a common top edge 638. The common top edge 638 extends for a longer length of the nose portion 626 of the adapter 612, and is generally centered along its longitudinal center line 622. In this embodiment The invention, each side or face 636, 637 forming the upper surface 630 of the adapter 612, has a generally flat configuration. Moreover, in this form of the invention, the sides 6,36, 637 which form the upper surface 630 of the adapter 612, are each inclined at an angle of approximately 35 ° relative to a horizontal plane. In the embodiment of the adapter illustrated 1 in Figure 26, the lower surface 640 of the adapter 612 has a complementary configuration relative to the upper surface 630. That is, the lower surface 640 of the nose portion 626 of the adapter 612 has two sides 646, 647 united or merging one in relation! with the other, by a common bottom edge 648, and arranged on the opposite side sides of the longitudinal centerline 622 of the adapter 612. The bottom sides 646, 647, in the same manner extend forward from the base portion 624 from adapter 612 to its free end. The common edge 648 that joins or fuses the two sides 646, 647 that form the lower surface 640, extends for a greater length of the nose portion 626 of the adapter, and is disposed in a generally central manner relative to the center line longitudinal 622. In this illustrated form of the invention, the two sides 646, 647 forming the lower surface 640 of the adapter 612, each have a generally planar configuration. Moreover, in this form of the invention, the sides 646, 647 forming the lower surface 640 of the nose portion of the adapter 612 are each inclined at an angle of approximately 35 ° relative to a horizontal plane. 'In the embodiment of the invention illustrated' in Figure 26, the angularly arranged sides 636 and 646, which partially form the upper and lower surfaces 630 and 640, respectively, and which are disposed towards one side of the longitudinal centerline 622 of the adapter 612, in the same manner they are joined with the other along a common side edge 639 extending longitudinally forward from the base portion 624 of the adapter 612. In a similar manner, with the embodiment of the invention illustrated in Figure 26, the angularly disposed sides of the 637 and 647, which partially form the upper and lower surfaces 630 and 640, respectively, and which are configured on an opposite side of the longitudinal axis 622 of the adapter 612, are joined to one another along a common lateral edge 649, extending longitudinally forward from the base portion 624 of the adapter 612. The generally planar configurations of the sides 636, 637 and 646, 647 of the upper and in surfaces. 630 and 640, respectively, provide to the nose portion 626 of the adapter 612, a configuration of generally rectangular cross-section, having an increasing cross-sectional area, measured from its front end.

As will be appreciated by those skilled in the art, and to improve the conjunction between the tooth and the adapter, the cross-sectional configurations of the portion of • the nose of the adapter and the blind cavity defined by the tooth, will generally correspond to one in relation to the other. Accordingly, if the nose portion of the adapter has a cross-sectional configuration similar to that illustrated in Figure 26, the blind cavity defined at the trailing end of the tooth will have a configuration of similar cross section, thus improving the conjunction between them. Similarly, if the nose portion of the adapter has a cross-sectional configuration similar to that illustrated in Fig. 29, the opening of the blind cavity toward the rear end of the tooth will have a corresponding cross-sectional configuration. The present invention offers several distinguishing features hitherto unknown in the devices of • the prior art. First, with the present invention, the The size or cross-sectional area of the nose portion of the adapter can be made from the same amount of material as comparable adapters previously known, while offering greater strength and rigidity. Therefore, even if the material or the weight of the adapter, its strength and rigidity is significantly increased. By aligning the cross-sectional configuration of the nose portion of the adapter relative to the base portion, a significant increase in material thickness is provided, both in the vertical and horizontal directions, thus allowing the adapter support significantly higher forces. As will be appreciated, the angular orientation of the sides forming the upper and lower surfaces of the adapter can be configured during manufacture for different operations and yet offer greater strength and durability beyond the cross-sectional configurations provided in the conjunction of a conventionally configured multi-piece tooth assembly. Accordingly, the cross-sectional design of the conjunction between the tooth, e, and the multi-piece tooth assembly adapter can be specifically configured to match the expected vertical or horizontal increments associated with the ground engaging tool. Second, with the present invention, the angular orientation of these components of the tooth to be scraped and the adapter forming the conjunction between them, allows the self-centering of a relatively loose fitted tooth in the adapter. Moreover, the components of the tooth and adapter of the tooth assembly in multiple pieces, have been modified in a significant way from the designs of teeth to dig in multiple previous pieces, to purposely distinguish the component parts of the present invention from • the prior art. That is, the angled or angled configuration of the nose portion of the adapter relative to the base or mounting portion, while offering the operating benefits described above, further serves to distinguish the adapter of the present invention from All other designs known so far. In a similar way, the angled configuration or the edge of the blind cavity or • bag in the back end portion of the tooth for digging, distinguishes the digging tooth of the present invention, from all others. Moreover, as will be appreciated by the experts in In this field, the angled orientation of the retaining bolt structure made with the present invention offers greater advantages over the vertical or horizontally disposed retaining bolt systems. As will be appreciated, the B configuration of the hole axis to accommodate and stop the The retaining bolt at a generally normal angle to opposite sides of the angled upper and lower surfaces of the adapter facilitates the manufacture of the adapter. Also, the angular orientation of the retaining bolt allows superior access to it, for Carry out repair and / or replacement of the tooth to dig. In addition, the materials that are being excavated and the vertical and horizontal movements of the excavating tooth assembly, as well as the forces resulting from it. same, have significantly less effect on the angularly disposed detent bolt of the present invention, compared to the retention bolt systems known hitherto. Additionally, the inclined orientation or edge of the retaining bolt structure offers ergonomic advantages during repair or replacement of the tooth for digging. These ergonomic fittings become more reality with the shovel or the loading implement in a lower vertical position. Moreover, the inclined orientation of the retaining bolt structure facilitates proper assembly and orientation of the digging tooth or excavator relative to the adapter, thus allowing the user to fully take advantage of the design features associated with these teeth for digging. From the above, it will be observed that numerous modifications and variations can be made without departing ^ > of the true spirit and scope of the novel concept of the present invention. It will be appreciated that the present disclosure is intended to provide for exemplifications of the present invention, and is not intended to limit the invention to the specific embodiments illustrated. The disclosure aims cover in the appended claims, all modifications and color variations that fall within the spirit and scope of the claims.
