ELEVATOR BUCKET Filed Sept. 20, 1938 l/n emor Leon W. Koser Patented Jan. 2, 1940 UNITED STATES PATENT OFFICE ELEVATOR BUCKET LeonW. Koser, Winnipeg, Manitoba, Canada Application September 20, 1938, Serial No. 230,836 2 Claims.v (Cl. 198-452) the handling thereof, reducing warehouse and shipping space and permitting of low freight 15 classification charges.
A further object of this invention is to provide a device of the character herewithin described which will eliminate the use of overlapping flanges at the rear of the bucket for the purpose 20 of presenting a smooth surface against the belt at the rear thereof.
A further object of this invention is to provide a device of the character herewithin described which can conveniently be shaped over a form and more accurately pressed to the desired form than has hitherto been possible with buckets made up from separate pieces.
A further object of this invention is to provide a device of the character herewithin de- 30 scribed in which the upper edges of the end walls thereof incline outwardly and upwardly to lessen the spillage of grain thereover.
A further object of this invention is to provide a device of the character herewithin described 5 in which the overlapping flanges thereof, act as a pair of tracks for the purpose of raising the dipping edge of the bucket slightly when the associated belt sags and the bucket scrapes the bottom of the loading pit.
40 With the above more important objects in view and such other minor objects as may appear as the specification proceeds, my invention consists essentially in the arrangement and construction of details all as hereinafter more particularly de- 5 scribed, reference being had to the accompany- I ing drawing, in which:
Figure 1 is a plan view of the shaped blank employed in the manufacture of my elevator bucket.
Figure 2 is a perspective illustration of a com- 50 pleted bucket. t Figure 3 is a side view of Figure 2. Figure 4 is a front view of Figure 2. In the drawing like characters of reference indicate corresponding parts in the different 55 figures.
My invention comprises a vertical rear wall I, provided with a pair of spaced apertures 2, for the purpose of attaching the completed bucket to an elevator belt. The side walls 3 constitute part of the blank illustrated in the 5 accompanying Figure 1, so that in the manufacture of my bucket, the blank is angulated along the lines 1 and by reference again to the accompanying Figure 1, it will be noted that the lines 4 converge from the edge 5 which constitutes the upper edge of the rear wall I.
It will also be noted that the upper edge 6 of each of the side walls 3 is aligned with the edge 5, from which it is obvious that when the blank is placed in a press, the edges 6 will incline outwardly and upwardly as most clearly illustrated in the accompanying Figure 3. In this way, the possibility of spillage of grain over the side walls of my bucket is lessened.
The portion 1 is formed into a curved base portion 8, the contour thereof being struck about two radii 9 and 10, thereby forming two arcs H and I2. The front wall portion I3 is continuous to the arc l2, this wall being flat and diverging outwardly and upwardly towards the upper edge It thereof.
By reference to the accompanying Figure 1, it will be noted that I provide a pair of flanges l5, which in the process of forming a completed bucket are angled inwardly as clearly illustrated in the accompanying Figures 2 and 4 to overlap the base 8 and the front wall [3. From which arrangement, it will now be apparent that the edges I6 and the turned edges I! provide the only joints in my construction. It will also be apparent that my inturned flanges l5 provide a peculiarly satisfactory support against the outward thrust of grain within the bucket upon the front wall l3.
It should finally be mentioned that the .overlapping flanges iii are spot welded at intervals to the edges [2 or rivets maybe employed for this purpose according as the bucket is large or small, after which the bucket is ready for bundling and shipping.
Since various modifications can be made in the above invention, and many apparently widely different embodiments of same, made within the scope of the claims without departing from the spirit and scope thereof, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense and I desire only such limitations placed thereon as are specifically expressed in the accompanying claims.
What I claim as my invention is:
1. An elevator bucket formed from a onepiece patterned blank, said bucket comprising a rear Wall, a pair of side walls continuous and integral therewith, a base and a front wall, said side walls converging inwardly towards said base, said base being integral and continuous with said rear wall and curving outwardly and upwardly, the curvature thereof conforming to two arcs, the first are being struck from a radius of greater length than the height of said rear wall, the second are being struck from a radius equal to approximately one-half the height of said lated inwardly and overlapping said base and said front wall to prevent deformity thereof under the weight of material within said bucket.
2. The bucket as defined in claim 1 in which each of said flanges extend right up to the edge of said front Wall to protect said edge against mutilation.
