HENRY W. OALDVVELL, OF CHICAGO, ILLINOIS.

ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 280,909, dated July 10, 1883.

(No model.)

To all whom, it may concern:

Be it known that I, HENRY W. CALDWELL, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Elevator-Buckets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in whieh- Figure 1 is a perspective view. Fig. 2 is a top view, and Fig. 3 is atop viewof a modication.

My invention relates to a strengtheningbrace for large size elevator-buckets, which is of such a nature that it will not interfere with the buckets being nested for storage or transportation.

My invention consists in points of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents a large size elevator-bucket. It has been customary to strengthen these buckets by means of a strip of metal secured to the top about the center, thus tying the sides of the bucket together; but a great objection to this way of strengthening these buckets is that they cannot be nested, or packed one within another, for storage and transportation, and thus they are made to take up a great deal of unnecessary room. With my improved brace the buckets can be packed as closely together as if they were not braced at all.

B represents the strengthening-strip, conformed to the transverse shape of the bucket and secured thereto preferably by means of rivets, as shown. I prefer to place this strip on the inside of the bucket and to form a groove in the bucket to receive it, so that its outer surface will be flush or smooth, or at least not project beyond the inner surface of the bucket, and thus it does not in any way interfere with the nesting of the buckets. I prefer to press the groove into the bucket, which would form a small rib, G, on the outer surface, but which would not to any material extent interfere with the nesting of the buckets. The top band, D, would be cut out to receive-the rib O.

The strip, if preferred, may be secured to the outside of the bucket, as shown in Fig. 3, and then it would not materially interfere with the nesting of the buckets.

While being of great practical importance, as stated, my invention does not deface or mar the appearance of the bucket; nor does it in any way interfere with the bucket doing its work, as does the strip extending across its mouth; and, moreover, this old style strip coming in contact with the grain is liable to be broken off in time, and causes unnecessary friction, and it also prevents a free discharge of the material from the bucket, causing it to scatter and drop down behind the leg of the elevator.

The brace can, of course, be secured to the inside of the bucket without the use of the groove, and would not to any great extent interfere with the nesting of the buckets.

I claim as my invention 1. An elevator -bucket having a central strengthening-strip conforming to its transverse shape and secured thereto by rivets and not extending above the edge thereof, substantially as and for the purpose set forth.

2. An elevator-bucket having a transverse groove to receive a strengthening brace or strip, substantially as and for the purpose set forth.

In presence of GEO. W. SroKELs, A. R. SHERRILL, Dwierrr Coons, J. H. SMITH.
