PULLEY BLOGK.

NITED STATES PATENT OFFIcE,
PULLEY- BLOCK.
SPECIFICATION forming part of Letters Patent No. 322,890, dated July 28, 1885.
Application filed February 23, 1884.
To all whom it may concern.-
Be it known that I, HUNTINGTON BEARD, of Fayetteville, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Pulley-Blocks, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a perspective of the block. Fig. 2 is a vertical transverse section. Fig. '3 is a top plan view of the block.
My invention relates to that class of pulleyblocks commonly called swivel-blocks.
The object of it is to strengthen and increase the durability of the wheel-bearings, and also to simplify and improve the construction of the block by corrugating the meeting edges of the frame-plates, so that they hold each other, and it is therefore necessary to use but one bolt to hold them together.
It consists of the several features specifically set forth in the claim hereto annexed.
It is constructed as follows: A is the pulleyblock, constructed with a bipartite frame, consisting'of two parts, a 1), comprising a seat for the swivel-ring c and a wheel, B. One half of the frame a is constructed with a corrugation or corrugations, h, (shown in ,the drawings as V-shaped) on each of the meeting edges so. At the top, in the center, is one half of the swivel-seat i, and near the bottom is the axle-hole m. The other half of the frame I) is the exact counterpart of the half a, except that where a is corrugated this half has corresponding indentations, s,to receive the corrugations h. r
The wheel B is cast with a soft body and (No model.)
rim, d, and chilled bearings e. I do this 'by so molding it that when cast the body and rim (1 remain soft, or like common cast-iron while the bearings e are chilled and hardened, so that their durability is greatly increased; or I can cast the hub and hearings in one piece and chill them and then cast the body and rim onto them.
In each of the frame-halves a, b I make bolt-hole, r.
The result of my construction is that I construct a pulley-block which is very simple and is all cast-iron excepting only the retain- 5i ing-bolt.
The corrugations h and indentations 8 act together to hold the meeting edges of the frame-halves in proper position and prevent their disp1acement,while only a single bolt is 5 necessary to hold thewhole block together, this bolt being located in the direct line of the greatest strain.
What I claim, and desire to secure by Letters Patent, is
A pulley-block constructed with a bipartite frame, a I), having corrugations h, and corresponding indentations, s, in the meeting edges, a swivel-seat, i, and swivel-ring D and Wheel B, having chilled bearings c, all held together 6 by a single bolt, substantially as shown and described.
In witness whereof I have hereunto set my hand.
HUNTINGTON BEARD.
