CHARLES R. FISLER, OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 247,490, dated September 2'7, 1881.
Application filed March 29, 1881.
To all whom it may concern:
Be it knownthat I, CHARLES R. FIsLER, residing in Chicago, in the county of Cook and State of Illinois, and acitizen of the United States, have invented a new and useful Improvement in Elevator-Buckets, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation. Fig.2 is a rear elevation. Fig. 3 is a central vertical section.
Fig. 4 is a front elevation- Fig. 5 is a horizontal section taken at line as of Fig. 3, looking up; Fig. 6, a side view before the front and bottom piece is attached. Fig. 7 shows the same as Fig. 6, before attaching the strengthening-piece. Fig. 8 is an edge View of the front and bottom piece beforeit isbent up in front. Fig. 9 is a plan of the same part as Fig. 8, with the edges turned over. Fig. 10 represents the blank from which the back and sides areformed. Fig.11 represents the blank from which the front and bottom are formed. Figs. 12 and 13 represent the front and rear strengthening-bands. Figs. 10, 11, 12, and 13 are on a smaller scale than the other figures.
My invention relates to buckets usedin elevating grain, meal, flour, &c.
It consistsin a peculiar manner of construction. I make the bucket from two pieces of sheet metal, formed and united without solder, and strengthened at the top by bands, all as hereinafter described, and specifically set forth in the claims.
In the drawings, A, Fig. 10, represents a blank from which the back and ends of the bucket are formed. The lower edge, a c a, and the edge I) of part of each side are first bent over at right angles, and are clipped where the corners come, and then the parts which form the sides are bent over along the dotted lines 0. The parts 01 d form the sides and 0 forms the back. Fig. 7 is a side view of this piece at this stage, there being a narrow flange extending outward from the lower edge of the back and sides. A strengthening-band, B, is then riveted to the back by a single rivet, and over this piece B the upper edge of the back and sides are turned, as shown in Fig. 6.
C, Fig. 11, represents the blank from which the front and bottom are made. The edges of the sides and rear end of this piece are turned (No model.)
over at right angles, as shown in Figs. 8 and 9, forming grooves f g h. Then the flangesa a a of the back and sides are slipped into the grooves ff 9, and the front of this piece is bent upward, and the flanges b b of the sides are slipped into the grooves h. The seams are then bent over, forming a double seam, as shown in Fig. 1. Then the strengthening piece or band D is secured b varivet,e, at each side, which passes through the band B and the sides of the bucket, and completes the same.
'i are holes for the rivets'by which the bucket is secured to an endless elevator-band.
I thus make a very strong bucketfrom only two pieces of sheet metal firmly secured together by double seams, strengthened at the top by two hands.
Heretofore an elevator-bucket has been constructed of two metal blanks joined together at their edges by flanges and solder, and strengthened at the upper edges by a continuous band of metal riveted in place. Such construction, not being myinv'ention, is not broadly claimed by me.
What I claim as new, and desire to secure by Letters Patent, is as follows:
1. An elevator-bucket consisting of two metal pieces, the piece 0 constituting the front and bottom, and having three of its edges 80 flanged to form the grooves f, g, and h, and the other piece, A, constituting the back and two sides of the bucket, and having flanged edges c, a, a, b, and b,which areinserted into the grooves f, g, and h, and secured by double- 8 5 seaming the parts, all as herein shown and dey scribed.
2. An elevator bucket consisting of the metal piece G, flanged along three of its sides to form the groovesf, g, and h, the metal piece 0 A, provided along its bottom and side edges with the flanges a a a b b, which are inserted within the grooves on the metal piece 0, and secured by double-seaming the parts, and the separate bands B and D, riveted to the upper 5 portions of the bucket and lappingeach other at the sides, all as hereinshown and'described.
