IMPROVEMENT IN SA'SH-BALANCES.
Specification forming part of Letters Patent No. 136,366, dated March 4, 1873. i
To all whom t't may concern:
Be it known that I, JoHN J. COWELL, of Newark, county of Essex and State of New Jersey, have invented certain new and useful Improvements in Pulleys for Window-Frames and other Purposes; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the let-ters of reference marked thereon and forming a part of this specification.
My invention consists in making the spurs for holding the ease of a sash-balance in the Wood with orifices behind them, so that said spurs may project forward and still draw from the mold; and it consists, also, in the peculiarshaped wedge and grooves for tightening the case in the wood.
The inner projecting Vsectional journal, as already set forth, is for the pulley-wheel to revolve upon, said Wheel B being cast with a hole in the center corresponding in size-and shape with the journal A. The parts may be secured together by means of a rivet through the journal A. The projections a and corresponding recesses a are made to intersect when the parts D are adjusted together, andare for the purpose of preventing said parts from slipping or becoming disengaged. Behind spur o is a cavity, made to facilitate the casting, &c. The tapering grooves b are for the purpose of inserting a wedge, in order to force the spurs cinto the wood, thereby tightening the box in the mortise and preventing it from slipping out; or the wedges inayv be grooved and the edges of the parts made wedge-shaped to correspond.
In order to prevent said wedges from slip- 2. The wedge b and corresponding openings b b, and nipples e', or their equivalents, when used as'and for the purposes herein set forth and described.
