JOSEPH WELFLE, OF HAMLER, OHIO.

ELEvATo R'- BUCK ET.

SPECIFICATION forming part of Letters PatentNo. 688,565,'dated December 10, 1901- Application filled J'uly 29, 1901- Serial No. 70,143. (No model.)

This invention relates to elevator-buckets,A

and more Aparticularly tothat class wherein the bucket is constructed of a single piece of" sheet metal, the objects had in view being to present a bucket in which those parts subjected to the greatest strain and wear shall be thoroughly reinforced and, further, so to associate the bottom with the sides as to pre! sent at the rear of the bucket two interlocked shoulders or abutments formed by the side aps where they are bent around the back of the bucket and the edges of the bottom where they are iianged around the sides, the shouldersoperating to relieve a large portion of the strainfrom the rivets that hold the partsV of the bucket assembled.

With these and other objects in-view, as will appear as the nature lof the invention is better understood, the same consists in the.

novel construction and combination of parts of an elevator-bucket, as will hereinafter be Vfully described, andspecilically pointed out in the claim. p Y

In the accompanying drawings, forming a partY of this specicat'ion, and in which like numerals of reference indicate corresponding parts, there is illustrated a form of embodiment of the invention capable of carrying the same into effect, it being understood that in the manufacture of the bucket the parts herein shown may be changed as to shape, proportion, and exact manner of assemblage without departing from the scope of the invention, and in these drawingsn` r' VFigure 1 is a view in perspective of Aa bucket constructed in accordance with the present invention. Fig. 2 is a view in transverse section. Fig. 3 is a viewl in plan of the blank before it is folded up to form'the bucket.

In carrying the invention into effect a piece of sheet metal, preferably sheet-iron, is taken 'and is stamped or otherwise formed into the' blank shown in Fig., 3. The parts composing theblankfcomprise two side flaps 1 and 2, two y side wings 3 and 4, and a body 5, the latter constituting when the blank is assembled the responding to the curvature of the wings 3 and 4, after which the side flaps 1 and 2 are bent in against the back of the bucket and are se- .l

cured in place by rivets 8, after which the upper portion of the body is bent down along `the rdotted line 9 over the reinforcing-rim on the side Iiaps and secured in position thereto by rivets 10, thereby presenting a reinforced rim of double thickness along the front and sides of the bucket and of four thicknesses for some distance inward from the sides, the side flaps being of sufficient width to extend past the'two outer openings 11 in the back of thebucket, through which are passed bolts or rivets forsecuring the bucket to the conveyer-belt, a center opening` 12 being provided for the reception of a third bolt or rivet. As it will be evident that the two end bolts or rivets will be those that will receive the greatest strain in the operation of the bucket, the advantage of having a four-ply structure at these points will of vcourse be appreciated. After the parts of the bucket are thus assembled the outer edges of the bottom are turned in over'the sides to present two curved flanges 13, one only of whichis shown, andvin order bulk of the shock transferred from the front to present the interlocking shoulders between ,A

edge of the'bucket rearward, thereby relievin g strain from the rivets 8 and 10 and oper- IOO itis so constructed and assembled as to be strong and durable in use and thoroughly capable without injury of sustaining the shocks to which it will be subjected in use.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is-

A bucket of the character specified, conl structed of a single piece of metal folded upon itself to present a reinforced rim, sides integral with the front, a back integral with the bottom, side liaps folded against the back,

an extension on the back folded down over the side iiaps thereby to present a four-ply structure near the corners of the back of the JOSEPH WELFLE.
