CHARLES C. SCAIFE, OF ALLEGHENY CITY, PENSYLVANIA.
METHOD -OF MAKING ELEVATOR-BUCKETS.
SPECIFICATION forming part of Letters Patent No. 349,754, dated September 23, 1886. 'Application filed June 17, 1886. Seri-.il No. 205,510. (No model.)
.To all whom, it may concern."
Be it known that I, CHARLES C. SCAIEE, of Allegheny City, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Elevator-Buckets; and I do hereby declare the following to be a full, clear, and eX act description thereof.
It is very desirableto make elevator-buckets of a single piece of metal, so that they shall be free from rivets and seams, and present smooth unbroken surfaces, because the discharge of the l contents is thereby facilitated, the bucket is tremely heavy and expensive.
not liable toA become clogged, and is not liable to catch upon or inj urethe trough or conductor in which it moves. Elevator-buckets having these qualities have been formed by casting out of malleable iron; but such buckets are eX- Consequently their use has been limited. It has been suggested to make suchy buckets out of a single piece of sheet metal by striking it up by any suitable dies, but, so far as I can ascertain, such a bucket was never successfully made until produced by me in the use of thev method I am about to explain. This was owing to the difiiculty of giving the proper shape and depth to the cup of metal, the strain of the stamping operation being too great for the strength and tenacity of the material. After long-continued eXperimentsI discovered my present method of making these buckets, and have had the same in extensive and successful practical operation for some time past. 1
To enable others. skilled in the art to make and use my invention, I will now describe it by reference to the accompanying drawings,"
in which- Y Figure 1 is a plan view of the die and plunger with which the first step of the operation is performed. Figs. 2 and 3 are vertical sections on thelines A A and B B of Fig. 1. Fig.

the. same after undergoing /the first step of the operation. Fig. Gis a longitudinal section of the second die and plunger. Fig. 7 is a crosssection of the product of the second die. Fig. 8 is a longitudinal view of the third die and plunger. Fig. 9 isa cross-section of the pro- Figs. 10 and 11 are longitudinal and cross sections of the fourth die and plunger. Fig. v12 is a View of the product ofthe fourth die. Fig. 18 is a view ofthe trimming-dies. Fig. 14 is a view of the trimmed blank. Fig. 15 is a viewof the finished bucket.
Like letters of reference indicate likeparts in each.
In practising this invention I take a blank, a, Fig. 4, of steel or iron, and place the same cold upon the surface of the die b. (Shown in Figs. 2 and 3.)' This die bis secured to the bed-plate of a drop-press of the ordinary construction, which press is provided with a clamping-ring, c, which descends upon and clamps the edge or edges of the blank a over the cavity b of the die b. The plunger d then descends through the clamping-ring and forces the middle portion of the blank a down into the cavity b, producing a shallow cup-shaped blank, such as is shown at a', Fig. 5.M The effeet of thisstamping operation upon the metal blank is to render it so hard that I nd it desirable to anneal it, which maybe donel by placing it in a heating-furnace and heating it up to a cherry red, and then permitting it to cool in the open air. This blank is then submitted to the operation ofthe die and plunger e f, (shown in Fig. 6,) which, being of greater depth and smaller diameter, have the effect of reducing the diameter and increasing the depth of the cup and producing a blank, a2, such as is shown in Fig. 7. The process of annealing is then repeated, and the blank a, after becoming cold, is submitted to the'operation of the dich and plungeri,l (shown in Fig.8,) which, being less in diameter and greater in depth, reduce the diameter and increase the depth of the blank, as shown at a3, Fig. 9. The blank is then heated; but instead of being permitted to cool it is taken directly from the heatingfurnace and put upon the die 7c, (shown in Figs. 10 and 11,) where the final shape is given to the cup by the plunger m, as shown at a4 in Fig. 12. This bucket has a round bottom,
ICO
the sideof the cup, as shown in Fig. 15, to constitute a re-enforeement or extra thickness of the metal at that point Where it is riveted or bolted to the belt. This method enables the material to stand the severe stamping` operation Without fracture. It is only by performing the last step ofthe operation upon the blank in a heated condition that I am able to give vit its proper shape. The wide mouth, narrow bottom, and great depth make it an ex- Vtremely difficult article to make, and'I know of no other practical Way of doing it except the one I have described. It is strong, light, of
proper shape to discharge its contents properly, and very durable.
What I cla-ini as my invention, and desire to secure by Letters Patent, is-
