POWER AGTUATED DIPPER Filed Aug. 26. 1951 i@ @f 'Lu- 5 Patented Feb. 7, 1933.y

UNITED STATE s PATaNToFI-*ICE `IoSEPH P. MURTAUGH, yor CHICAGO HEIGHTS, ILLINOIS, ASSIGNQETC .IIIIIERIC'AN` MANGANESE STEEL COMPANY, or CHICAGO HEIGHTS, ILLINOIS, A- CORPORATION E POWER ACTUATED DIFFER Application led August 26, 1931. Serial No. 559,433. g

This invention relates tofpowery actuated dippers, buckets and the like excavating irnplements and has among its important objects to provide an improved body assembly including an interchangeable lip member and renewable tooth structure.

The interchangeable lip assembly of the present case is allied in principle to the disclosure in application Serial No, 583,317 tiled December 26, 1931, in both cases the purpose j being to'supply the user with a dipper body and a plurality of lip members so that the user may change the clipper body over, by interchange of lips, to meet different excavating requirements. l

While the foregoing statement is indicative in a general wayfof the nature of the inven-` tion, other objects and advantages will be apparent upon a full understanding of the construction and cooperative relationship of the severalparts of the. implement. j

One type of construction for reducing the invention to practice is presented herein by Way ot' exemplification but it is to be understood that the invention is susceptible of embodment in still other structurally modiiied for-ms without departing from'the spirit of the invention, as defined by the subjoined Inltheaccoinpanying one sheet of draw- Figurev- 1is a viewin side elevation of a dipperl constructed in accordancewith the present invention;

'Figure 2 isa view ini-ront elevation of a portion of thedipper;

Figure-3 is aview similar to Figure 1 but showing the lip and tooth assembly in secl/ tion; i j j Figure 4 is a detail view in sid-e elevation of the front portion of one of the side walls showing one form ot anchoring means for an interchangeable lip member;

Figure 5 is adetail view in side elevation of a lip member; f

Figure 6 isa similar view of a tooth. and

Figure 7 is a view in side elevation of a modified form of lip and tooth assembly. f

Referring now to thedrawing 'in detail, 5 represents the dipp'er body comprising a one Piece Casting having integral front,`side and

back walls

6, 7 and 8 respectively.

The back Wall 8 carries the usual lifting ear 9, the hinge bearings-10 and the stick bearings 11.

and comprises a cutting edge 13 made to acvand 6) which are adapted to Straddle the cutting edge withl a close clamping it. The jaw 16 of each tooth is made with a Continuation4 17'which is passedthroughopenings 18 made to receive them in the

meeting flanges

19 and 20 on the lip and front wall respectively. After extending through these openings, rivets or some other double ended pin devices 21 suitable for the purpose are secured in the registering

openings

22 and 23 to lock the jaws in place and at the same time mount the lip on the front wall of the body. The connection thus serves the dual purpose of locking the teeth to the lip and locking the lip' with. the teeth thereon to the front wall of the body. The flange 20 on the front wall is cast with pairs of reinforcing webs 24 which are The `lip member 12 is separately formed Y commodate separately formed interlocking teeth 14. The teeth for this purpose are made spaced to lit the width of the continuations of the jaws 16 (see Fig. 2). This aids in holding the jaws in parallel alignment and adds rigidity to the structure.

yThe integral side members 25 of the lip .are supported upon the edge of the side walls of the body and may be joined doubleended pins or the like 26.

Referring to Figure T, itwill be seen that the teeth and lip may be either cast as an integral assembly or else separately formed and thereto by welded together. ll'hen this is resorted to the llange 19 on the lip need not be used; otherwise the assembly is effected as in the first y form.

l claim:

1. A power actuated dipper comprising a body, a lip, teeth for said lip and means for anchoring the teeth to both the lip and body, i i

comprising integral jaws for the teeth adapted to straddle the lip, an integral extension for one jaw of each tooth having an opening adjacent the end 1hereof,,projectingiiauges on the body and lip having registering openings through which said integral extensions on the jaws project, and pin devices on the body seated in the openings in the extensions of the jaws.

2. A lip and tooth assembly for power actuated dippers, comprising in combination, a cutting edge on the lip, teeth having jaws straddling said cutting edge, a flange on the lip having a series of spaced openings therein and means on one jaw of each tooth projecting through said openings and providing means for securing the lip and tooth assembl to the body of the dipper of the class descri ed.

3. A lip and tooth assembly for power actuated dippers, comprising in combination, a

' cutting edge on the lip, teeth having jaws straddling said cutting edge a flange on the lip having a series of spaced openings there- `in and means on one' jaw of each tooth projecting through said openings and providing means for joining the teeth to the li 4. A power actuated dipper emb ying in its construction a body providing front and side walls, a flange formed on the upper edge of the front wall having openings therein, reinforcing ribs on the front wall merging with said flange, a separately formed lip for said body, a ange on said lip adapted to bear against the flange on the front wall of the body and having openings therein adapted to register with openings in said first named flange, teeth for said lip having jaws adapted to straddle the lip, an extension on one jaw of each tooth adapted to project through the registering openings in said flanges and seat between the reinforcing ribs on the front wall of the body. Y

5. A power actuated dipper comprisinva a bod a lip, teeth for said lip and means or anc oring the teeth to both the lip and body, comprising integral jaws for the teeth adapted to straddle the lip, an integral extension for one jaw of each tooth, projecting flanges on the body and lip havlng registering op-enings through which said integral extensions on said jaws project, and means for securing said extensions to said body.

6. A power actuated dipper embodying in its construction a body providing front and side walls, a flange formed on the upper edge of the front wall having openings therein, reinforcing ribs on the front wall merging with said -flange, a lip for lsaid body formed separately therefrom, teeth for said lip having jaws adapted to straddle the lip, an extension on one jaw of each tooth adaptedto project through one of said openings in said flange and seat between two of the reinforcing ribs on the front wall of the body.

7. A power actuated dipper embodying in its construction a body providing front and side walls, a flange formed on the upper edge of the front wall having openings therein, re-

wall, a digging lip mem r adapted for detachable securement to said front wall, said lip including a plurality of integral tonguelike extensions rearwardly extending therefrom, said front wall including a flanged forward edge provided with a plurality of openings adapted to receive said extensions of said lip and means for fastening said extensions to said front wall rearwardly of said fianged edge.
