WOOD-=RHVI PULLEY.
SPECIFICATION forming part of Letters Patent No. 309,007, dated December 9, 1884.
Application filed May 19, 1884. (No model.)
T0 00% whom it may concern.-
Be it known that we, FREDERIoK TAYLOR and KIRKLEY HYDE, both citizens of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in W'ood-Rim Pulleys, of which the following is a specification.
Our invention relates to that class of woodrim pulleys in which the ends of the middle or foundation fellies engage directly with the outer ends of the spider-arms; and it consists in so shaping the parts named that the shrinking of the wood of said fellies shall cause their ends to embrace the ends of the arms more closely.
In the accompanying drawings, Figure 1 is a side elevation of such a pulley, a part of the lags or outer fellies being broken away to show the ledges at the ends of the arms and the recesses in the ends of the foundation-fellies. Fig. 2 is a central cross-section of the same on line X X in Fig. 1.
A is a metallic spider consisting of the hub dation fellies, B, are each provided at each end with a notch adapted to receive one of the wedge-shaped ledges a and are long enough to meet outside of the ends of the arms. Each middle felly should fit so closely between two adjacent arms as to require considerable force to press it into place. ,When the middle fellies are in place, they form a foundation, to which the outer fellies are then secured by screws or nails and glue in the usual manner.
In the above-described construction it will be seen that any shrinking of the wood of the middle felly will cause its ends to pinch the ledges more closely.
We claim as our invention- 1. The combination of the wooden foundation-fellies having openings in the ends thereof, and the metallic spider having ledges or projections on the outer ends of its arms, adapted to enter said openings and to be more firmly held therein by the shrinking of the wood of said fellies, as and for the purpose specified.
2. The combination of a metallic spider having the outer ends of its arms provided with wedge-shaped ledges, and the foundation-fellies having their ends provided with notches to fit such ledges, as and for the purpose specified.
