DIPPER BUCKET Filed Nv. 4, 1929 Patentedliulry 2s, 1931 UNITED STATES EARL H. FUNDOM, OF LIMA, OHIO, AssIeNoR` vTo Pnzrrrioivn MLLIKEN COMPANY,Or CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE DIPPER BUCKET Application filed November My invention relates to dipper buckets such as are used for excavating, dredging, transferring loose material, 0r for other similar work.

My primary object is to provide a dipper bucket of such construction that the material to be transferred in the bucket may be scraped thereby into a position in which the loading of 'the bucket may be facilitated, or the inaterial discharged from the bucket may be leveled by the bucket or shifted to a different location, as forexample into a pile.

Referring to the accompanying drawings:

Figure 1 is a View in side elevation of. a portion of an excavator apparatus comprising a dipper bucket embodying my improvement. Y

Figure 2 is a bottom plan view of the bucket and a portion of the supporting structure therefor; and Figure 3, a brokenl enlarged section taken at the line 3 on Fig. 1 and viewed in Jthe direction of the arrow.

My invention generally stated consists in providing on the dipper bucket at its bottom and preferably at the lower edge of its front portion. a scraping device, in the form of a lip, which extends into a position in which it may engage with, and scrapeto the desired position, material to be transferred in the bucket or the material after it has been transferred in the bucket.

In the particular illustrated embodiment of my invention, the dipper shown and represented generally at 4 comprises a front section 5 shown as equipped at its upper edge with dipper teeth 6, a back portion 7, and side portions 8. p

In this embodiment of the invention the scraper above referred to is in the form of a lip 9 located at the lower edge of the front 5 and integrally formed therewith, though it is not necessary that it be so formed, the lip shown having its end walls downwardly convergent as representedV at 10.

The lip 9 extends in front of the opening in the bottom of the bucket, this opening being provided with any suitable removable closure, as for example a sliding door such as that represented at 11. The door 11 extends at its opposite lateral edges into in- 4,',1-9'29. seriai no'. 404,776.

wardly opening :channels defined" by the lower edges of certain portions ofthe side wallsoft'liebucket and the inwardly extendn `ing lugs 13 provided on certain of the other members forming the side wall structure of the bucket, the side wall structure of the bucket being provided with rearwardlyV projecting extensions 14 presenting guide lugs 15 in which the door, at its edges, is slidable.

Th-e bucket is shown as connected with the outer end of a dipper stick 16 in accordance with common practice, this stick'being associated with a boom 17 as commonly proto be transferred therein with its scraper lipy 9 engaging the material, the material maybe drawn into a pile or otherwise suitably dis-V placed for facilitating the loading of the bucket and the material discharged from the bucket may be either leveled or moved into 'the desired position, as for example intoV a pile, by drawing the bucket along the mate-A rial with the scraper lip 9 extending into theV material.

The structure thus provided, therefore, f

affords the dual adaptability of transferring material therein and also the shifting or moving of the material eitherl before Or after its transference in the bucket.

while I have interfered amusant-ed particular construction embodying my inf vention, I do not wish to be understood as intending to limit it thereto as the same may v be variously modified and altered without de-V parting from the spirit of my invention.

What I claim as new, and desireV to secure by Letters Patent, is:

1. A dipper bucket having a digging portion at its upper ledge and provided at its lower portion Vwith. a scraper element extending below the bottom of the bucket, for the purpose setl forth. y

2. A dipper bucket having a digging'portion at its upper edge and provided at the lower edge of its front portion With a scraper element extending beioW the bottom of the bucket, for the purpose setv forth.

3. A dipper bucket having a digging portion at its upper edge and provided at the lower edge of its front portion With a lip depending belovv the bottom of the bucket Y y and forming a scraper element, for the purpose set forth. f

4. A dipper bucket having a digging por.

tionV at its upper edge and provided atits lovver portion with a lip extend-ing below the bottom of the bucket and forming a scraper element With'its end portions dovvnv Wardly converging.
