Best Mode for Carrying Out the Invention In the exemplary embodiment of the invention as disclosed in the drawing, an earthworking element gen- `
erally designated 10 is illustratively shown to com-prise a bulLdozer blade, it being understood that the invention is equally applicable to other forms of earthworking elements, such as loader buckets, etc.
Illustratively, the bulldozer blade includes a mold board 20, a pair of sidewalls 11 and 12 comprising plate member secured to the opposite sides of the mold board. Each of the end wall plates defines a for-wardly opening recess 13 and a lower edge portion 14.
The present invention is concerned with the reinforc-ing of the end wall members and includes a number of improved reinforcing elements, as will be discussed . . : . , , . . , ~ . ,, . . , :. , ,. , 1~3gl37 in greater detail herefollowing.
More specifically, lower edge portion 14 of the sidewall members is reinforced by an improved U- -section wear member 15. The sidewall members are re-inforced further by a half arrow reinforcing element 16 received in recess 13. The sidewall member rear-wardly of the heavy wear member 17 is further rein-forced by a wear plate 18.
As further shown i~ Figure 1, the earthwork-ing implement lO includes a bit support 19 extendingbetween the sidewall members at the lower edge of the moldboard 20. A plurality of bits generally desig-nated 21 are mounted to the bit support 19 by suitable means, such as bolts (not shown). The bits include end bits 22 which overlap the U-section wear member 15 and sidewall member lower portions 14, as shown in Figure 5.
The configuration of wear member 15 may best be seen by reference to Figure 2. As shown therein, the wear member 15 comprises a U-section element having an outer leg 23, an inner leg 24, and a lower bight portion 25 cooperatively defining a slot 48. As shown, the outer leg 23 has a height substantially greater than the inner leg 24 and extends forwardly of the front surface 26 of the inner leg. In the illustrated embodiment,the outer leg 23 is provided with a forward-ly and inwardly opening recess 27 adapted to receive the distal end 28 of the end bit support 19 and accom-modate a weld l9a between edge portions 14 and end bit support 19, as shown in Figure 5.
The forward extension of the outer leg 23 is substantially equal to the thickness of the bit sup-port 19, as shown in Figure 5. Thus, as illustrated in broken lines in Figure 4, the end bit 22 may bear against the front surface 29 of the extension 30 of ., : , : ............................ . .
~, ~
the outer leg 23 to extend to outwardly of wear member 15.
As shown in Figures 7 and 8, lower edge por-tion 14 of sidewall member 11 extends downwardly be-tween legs 23 and 24 of the wear member. Leg 23 isprovided with a pair of openings 31 and end wall por-tion 14 is provided with a corresponding pair of open-ings 32 for receiving a pair of locking pins 33 (Figs.
1 and 2). As shown in Figure 8, the locking pins ex-tend further into aligned openings 34 in the inner leg24 of the wear member 15. A pair of locking rings 35 may be provided for locking the pin 33 against axial displacement. As shown in Figure 8, the locking rings, when utilized, are received in suitable grooves 36 in the locking pin 33 and are disposed within opposed, inwardly facing recesses 37 of the legs 23 and 24, per-mitting the locking rings to snap into place in the grooves 36 upon insertion of the locking pin 33 through the aligned openings. Thus, the wear member 15 may be readily removably secured to the lower edge portion 14 of the sidewall plates 11 and 12.
As indicated above and as shown in Figures 3 and 6, the sidewall plates are further reinforced by half arrow elements 16. Each element 16 is defined by an outer plate section 38 having a front portion 39 and a rear portion 40. An inner tapered section 41 is formed integrally with the plate section front portion 39 and widens rearwardly to a transverse shoulder sur-face 42. A weld 43a is provided rearwardly of surface 42 and forwardly of the front edge 44 of the sidewall plate defining the recess 13. Thus, the weld 43a is effectively recessed behind the wedge-shaped portion 41 for protection thereof during use of the earthwork-ing element. A similar weld 43b is provided at the rear end of plate 38 for securing the plate thereat . . ~ .
,., .34~37 to sidewall plate 11, as seen in Figure 6. As shown, weld 43b is protected against wear by the element 16.
As shown in Figure 6, the rear portion 40 of the outer section 38 overlies the outer surface of the sidewall to provide further rigidification of the sidewall plates. The forward tip 45 of the half arrow element defines a relatively sharp leading edge por-tion of the half arrow element for improved penetra-tion.
As seen in Figure 7, plate 18 and end wall plate portion 14 have a cumulative thickness substan-tially equal to the cumulative width of slot 48 and outer leg 23 of the wear member 15. Wear plate 18 has a thickness substantially similar to that of the thick-ness of outer leg 23 of the wear member 15 and, thus, as seen in Figure 7, the outer surfaces of the wear member 15 and replaceable wear plate 18 are substan-tially flush for further improved earthworking oper-ation and improved wear life.
As seen in Figure 2, the rear wall 46 of the wear member 15 extends between the legs 23 and 24 and has a height substantially equal to the height of the outer leg 23 so as to define a rear abutment for the sidewall plate portion 14. As shown in Figures 7 and 8, the lower surface 47 of bight 25 of wear member 15 is tapered downwardly so as to effectively define a V-section surface to provide a reduced footprint and better hlade penetration during use of the earthwork-ing implement.
As the wear member 15 is secured to the lower edge portion 14 of the sidewall plate members by pin means rather than welding means, the wear member may be formed as a casting of wear-resistant alloy steel providing further improved long troublefree life of the earthworking implement.
;
~ ~3~137 Industrial Applicability The use of the improved readily replaceable wear member 15 provides a substantial improvement in the facilitated maintenance of such earthworking imple-ments. In the prior art constructions wherein heavywear plates were welded on the sidewall members, the difficulty of replacement of the wear plates caused the shoe wear to be ignored until the end bit reten-tion became a serious problem. By providing the im-proved readily replaceable U-section wear members 15, the rapid wear of the leading edge of the sidewall plates and lower shoe member has been effectively mini-mized so as to provide substantially improved useful-ness with effectively minimum maintenance of the earth-working implement. As the shoe member may be readilyreplaced, only a short down time is required to effect the change from a worn member to a replacement member.
As indicated above, as the wear member is mechanically secured to the earthworking implement, a long life wear-resistant alloy steel material may be utilized, further minimizing maintenance requirements.
The improved reinforcing means may be util-ized in a wide range of earthworking implements, in-cluding the bulldozer blade implement of the disclosed embodiment, as will be obvious to those skilled in the art.
The improved structural integrity of the earth-working element utilizing the reinforcing means of the present invention is extremely simple and economical of construction while yet providing the highly desirable ~eatures discussed above.
Other aspects, objects and advantages of this invention can be obtained from a study of the drawings, the disclosure and the appended claims. The foregoing disclosure of specific embodiments is illustrative of , - : -' ~

Best Mode for Carrying Out the Invention In the exemplary embodiment of the invention as disclosed in the drawing, an earthworking element gen- `
erally designated 10 is illustratively shown to com-prise a bulLdozer blade, it being understood that the invention is equally applicable to other forms of earthworking elements, such as loader buckets, etc.
Illustratively, the bulldozer blade includes a mold board 20, a pair of sidewalls 11 and 12 comprising plate member secured to the opposite sides of the mold board. Each of the end wall plates defines a for-wardly opening recess 13 and a lower edge portion 14.
The present invention is concerned with the reinforc-ing of the end wall members and includes a number of improved reinforcing elements, as will be discussed . . : . , , . . , ~ . ,, . . , :. , ,. , 1~3gl37 in greater detail herefollowing.
More specifically, lower edge portion 14 of the sidewall members is reinforced by an improved U- -section wear member 15. The sidewall members are re-inforced further by a half arrow reinforcing element 16 received in recess 13. The sidewall member rear-wardly of the heavy wear member 17 is further rein-forced by a wear plate 18.
As further shown i~ Figure 1, the earthwork-ing implement lO includes a bit support 19 extendingbetween the sidewall members at the lower edge of the moldboard 20. A plurality of bits generally desig-nated 21 are mounted to the bit support 19 by suitable means, such as bolts (not shown). The bits include end bits 22 which overlap the U-section wear member 15 and sidewall member lower portions 14, as shown in Figure 5.
The configuration of wear member 15 may best be seen by reference to Figure 2. As shown therein, the wear member 15 comprises a U-section element having an outer leg 23, an inner leg 24, and a lower bight portion 25 cooperatively defining a slot 48. As shown, the outer leg 23 has a height substantially greater than the inner leg 24 and extends forwardly of the front surface 26 of the inner leg. In the illustrated embodiment,the outer leg 23 is provided with a forward-ly and inwardly opening recess 27 adapted to receive the distal end 28 of the end bit support 19 and accom-modate a weld l9a between edge portions 14 and end bit support 19, as shown in Figure 5.
The forward extension of the outer leg 23 is substantially equal to the thickness of the bit sup-port 19, as shown in Figure 5. Thus, as illustrated in broken lines in Figure 4, the end bit 22 may bear against the front surface 29 of the extension 30 of ., : , : ............................ . .

the outer leg 23 to extend to outwardly of wear member 15.
As shown in Figures 7 and 8, lower edge por-tion 14 of sidewall member 11 extends downwardly be-tween legs 23 and 24 of the wear member. Leg 23 isprovided with a pair of openings 31 and end wall por-tion 14 is provided with a corresponding pair of open-ings 32 for receiving a pair of locking pins 33 (Figs.
1 and 2). As shown in Figure 8, the locking pins ex-tend further into aligned openings 34 in the inner leg24 of the wear member 15. A pair of locking rings 35 may be provided for locking the pin 33 against axial displacement. As shown in Figure 8, the locking rings, when utilized, are received in suitable grooves 36 in the locking pin 33 and are disposed within opposed, inwardly facing recesses 37 of the legs 23 and 24, per-mitting the locking rings to snap into place in the grooves 36 upon insertion of the locking pin 33 through the aligned openings. Thus, the wear member 15 may be readily removably secured to the lower edge portion 14 of the sidewall plates 11 and 12.
As indicated above and as shown in Figures 3 and 6, the sidewall plates are further reinforced by half arrow elements 16. Each element 16 is defined by an outer plate section 38 having a front portion 39 and a rear portion 40. An inner tapered section 41 is formed integrally with the plate section front portion 39 and widens rearwardly to a transverse shoulder sur-face 42. A weld 43a is provided rearwardly of surface 42 and forwardly of the front edge 44 of the sidewall plate defining the recess 13. Thus, the weld 43a is effectively recessed behind the wedge-shaped portion 41 for protection thereof during use of the earthwork-ing element. A similar weld 43b is provided at the rear end of plate 38 for securing the plate thereat . . ~ .
,., .34~37 to sidewall plate 11, as seen in Figure 6. As shown, weld 43b is protected against wear by the element 16.
As shown in Figure 6, the rear portion 40 of the outer section 38 overlies the outer surface of the sidewall to provide further rigidification of the sidewall plates. The forward tip 45 of the half arrow element defines a relatively sharp leading edge por-tion of the half arrow element for improved penetra-tion.
As seen in Figure 7, plate 18 and end wall plate portion 14 have a cumulative thickness substan-tially equal to the cumulative width of slot 48 and outer leg 23 of the wear member 15. Wear plate 18 has a thickness substantially similar to that of the thick-ness of outer leg 23 of the wear member 15 and, thus, as seen in Figure 7, the outer surfaces of the wear member 15 and replaceable wear plate 18 are substan-tially flush for further improved earthworking oper-ation and improved wear life.
As seen in Figure 2, the rear wall 46 of the wear member 15 extends between the legs 23 and 24 and has a height substantially equal to the height of the outer leg 23 so as to define a rear abutment for the sidewall plate portion 14. As shown in Figures 7 and 8, the lower surface 47 of bight 25 of wear member 15 is tapered downwardly so as to effectively define a V-section surface to provide a reduced footprint and better hlade penetration during use of the earthwork-ing implement.
As the wear member 15 is secured to the lower edge portion 14 of the sidewall plate members by pin means rather than welding means, the wear member may be formed as a casting of wear-resistant alloy steel providing further improved long troublefree life of the earthworking implement.
