CAST-METAL DEEPER-BODY.
Specification of Letters Patent.
Application filed January 11, 1912. Serial No. 670,601.
Patented July 2, 1912.
To all whom 'it may concern:
Be it known that we, WALTER S. McKEn,
a citizen 'of the United States, and a resident State of Minnesota, have made and invented certain new and useful Improvements in Cast-Metal Dipper-Bodies, of which the following is a specification.
Our invention relates to dippers for excavating, dredging and similar machines designed to scoop up or dig a material and deposit it upon cars, scows, or similar devices for transporting the material to a distance, and more particularly to such dippers as are formed from castmetal such as cast manganese steel.
The main or body portion of dippers of the type above referred to are in accordance with the most approved practice formed from twomanganese steel castingseach com prising approximately onehalf of the dipper body, the two parts being secured together along joints in the sides of the dipper;
and one object of our invention is to provide a dipperbody formed in a single piece from east manganese steel, whereby the same is materially simplified, the cost thereof greatly reduced, and a stronger body procured than when the same is formed in several parts.
Further objects of our invention are to provide various detail features in and relating particularly to cast metal "dipper bodies formed in a single piece although the same are also capable of use with dipper bodies formed from cast metal in two or more pieces.
With the above objects of invention in view, our invention consists in the various features hereinafter particularly referred to and described, and claimed in the clauses of the concluding claims, and in such variations and modifications thereof as will be obvious to those skilled in the art to which our invention relates.
In the drawings accompanyingand forming a part of this application, and wherein the preferred embodiment of our invention is illustrated; Figure 1 is a view showing our improved dipper body in side elevation; Fig. 2 is a view showing the same in plan;
to the front wall of the dipper.
Fig. 3 is a fragmentary view showing a sectlon upon a plane indicated by the line 3-3, Fig. 2; Fig. 4 is a fragmentary view showinga section upon a plane indicated by the line 44, Fig. 2; Fig. 5 is a fragmentary view showing a section upon a lane indicated by the line 5-5, Fig. 1; ig. 6 is a fragmentary "iew showing a section upon a plane indicated by the line 6-6, Fig. 1; Fig. 7 is a view showing a side elevation of the dipper body made up of two parts and equipped with certain features of our invention; and, Fig. 8 is a view-similar to Fig. 4 but showing a tooth member secured Referring to the drawings, the reference numeral 7 designates the body portion of our improved dipper, the stme being strengthened at its upper and lower ends by means of ribs 8, 9 and having a plurality of lugs 10 formed upon its rear wall to which lugs the mechanism for operating the dipper is pivotally connected, but which mechanism is not shown "as the same forms no part of our invention. Lugs 11 are also provided upon the rear wall of the dipper body, which lugs serve as supports for the hinged bot-.
dipper body is also provided with a series of longitudinally extendin tooth seats 15 located upon the inner sur ace of the front wall and formed integrally with the body portion 7.
The reference character 16 designates a lip formed separatefrom the dipper body and detachably secured to the front portion of the upper edge thereof, this lip being made detachable 1n order that it may be renewed when worn without necessitating the it is subjected to the greatest wear.
upper edge of the lip 16 is rovided with a.
renewal of the entire body portion of the dipper. The lip is rabbeted, as best shown, at 17 ,Fig. 4, and the lower edge 18 thereofg .abuts against the upper ends of the tooth seats 15 above referred to. The thicker upper edge of the lip extends over the upper edge of'the' dipper body as best'shown in 'Fig. 4, in order to secure astrong 'oint between the lip and body and provi e an in: creased thickness of lip at the place 'wl ilefie. e
30 21 extending over the-edge of the lip and downward along the exterior surface thereof and the lower end of which abuts against the upper edge of the body portion to thereby form a firm support for the tooth memher; and the said member has a shankportion 22 which extends along the inner surface of the body portion and rests upon the tooth seats 15 hereinbefore referred to. The tooth member is securedto the dip er body bymeans of bolts, rivets orequiva ent fastening devices, as shown at 23; which fasten ing means extend through the longitudinally extending ribs 13. 1
In referring to the member 20 as a tooth member, it is intended to include the same whether made in a single piece, as shown in the drawings, or with a'detachable point, it being common in the art to form a dipper tooth either as a si'ngleintegral structure,
as shown in the drawings-, or with a detachable point portion at its upper end.
The reference character 24 designates pro- I jecting lugs located adjacent the upper edge of the dipper body and formed integrally therewith, and 25 are cars located one upon each side of the dip er body and secured thereto, the upper ends of which ears abut against the lugs 24, which lugs therefore receive the greater part-of the strain when the dipper is in use, it bei understood that the ends of a suitable liftmg bail are connected with the dipper through these lugs.
The reference character 26 designates a wearin piece formed separate from the dipper bo y and secured to the lower edge of the front wall thereof, as will be understoodfrom Fig. 11 This wearing piece is made detachable from the dipper body in order that it may be renewed when worn, and the location thereof is at the place where the greatest amount of wear occurs when the dipper is.
in use, from which it follows that this wearing piece may be renewed when Worn without necessitating the renewal of the entire dipper body; it being found in practice that a single dipper body may be used indefinitely if rovided with a detachable wearing piece, su not provided the lower edge of the out portion of the body would be worn to such an extent as to seriously interfere with the further use of the dipper after a comparatively short time. The wearin piece 26 fits into a recess extending across t e dipper front and formed in the exterior surface of the rib. .9, and the same is provided with a series of ribs 27, which ribs form continuations of the ribs 13 when the wearing piece is secured in place. A further object of the wearing piece 26'is to prevent the rivets whereby the stirrup 28 is secured in place from being worn away, the stirrup being provided, it will be understood, for the purposeof receiving the as.-26, whereas if such iece was,
end of a latch, not shown, carried by the 1 swinging door 12 and whereby it is held in a closed position. The wearing strip 26 extends across the entire front of the dipper, as shown in Fig. 5, and terminates adjacent the place where the front and sides merge with one another.
p In- Fig. 7 I have shown a dipper body made up of two parts 29-30 each of which parts form substantiallyone-half of the dipper body, and which parts are joined together along a vertically extending point, as shown located in the sides of the dipper body, and mid-way between the front and rear faces thereof. In this figure, the front portion 29 of the dipper body is rovided with a detachable lip 31 similar to tlie lip 16 and with a series of longitudinally extend-- in ribs 32 similar to the ribs 13 hereinbefore r erred to. The lower edge of the front'of the dipper is also provided with a detachable wearing piece 33 slmilar to the wearing piece 26, and which wearing piece rests'in the recess in the front wall of the dipper and has ribs which form continuations of the ribs 33,
the same as hereinbefore explained when describing the form of our invention shown in Figs. 1 to 6.
Having thus described and explained our invention, we claim' and desire to secure by Letters Patent: a
1. In a dipper for excavating, dredging, and similar machines, a dipper body haV-e ing a series of longitudinally extending ribs 3. In a dipper for excavating, dredging,
and similar machines, a dipper body having a series of longitudinally extending ribs formed integrally therewith and located upon the outer surface of its front wall;
and a wearing piece formed separate fromsaid body and detachably secured to the lower'edge of the outer surface of the front wall of said body, saidwearing piece having a series of ribs which form continuations of the ribs aforesaid when said weareled; a lip formed separate from said body Y and detachably secured to the upper edge thereof, said hp having a recess formed 1n its upper edge; and a tooth member formed separate from said body and having a shank portion extending along the inner surface of the front wall of sald body and a hook 'portion extending over the edge of said lipand downward along the exterior surface thereof and the extremity of which hook portion abuts against the'up'per end of one i: of said'ribs, the upfiielr portion of said tooth 1n said hp.
member lying wi the recess aforesaid 5. Ina dipper for excavating, dredging and similar machines, a dipper body having a series of longitudinally extending ribs' formed integrally with and located upon the outer surface of the front wall thereof and the upper ends of which'ribs are beveled; a lip formed separate from said body and detachably secured to the upper .edge' thereof; and a toothrmember formed separate from said body and having a shank' portion extending alon the inner surface of the front wall of said body and a hook' portion extending over .the edge of said lip and downward along the exterior surface thereof and the extremity of which book portion abuts against the upper end of one of said ribs.
