ABRAM SHEAR, O13 PLYMOUTH, MICHIGAN.
Letters Patent N0. 114,870, dated May 16, 1871.
IMPROVEMENT IN MECHANICAL MOVEMENTS.
The Schedule referred to in these Letters Patent and making part of the sanie.
being had to the accompanying drawing and to theletters of reference marked thereon and being a part of this specification, in which- Figure 1 is a perspective view or my invention.
Figure 2 is a vertical section on the linex x in fig. 1.
Like letters indicate like parts in each figure.
This invention has-for its object the construction and operation of a device for equalizing the strain upon cranks when they are employed inoperating pitmen which are designed to lift any heavy bodies, the'reby'avoiding the necessity of constructing very large balance-wheels for the purpose of storing power to compel the cranks to pass their centers and-to lift heavy bodies.
.The invention consists in the employment of a spring so arranged that in the upward reciprocation of the pitman it will assist in raising the body attached to said pitinan.
- In the accompanying drawing- I A represents a frame which supports the working parts of the device, and 4 B is a shaft properly journaled at each end to the frame.
A geared wheel, 0, meshes into and engages with the pinion D, secured upon the double crank-shaft E. Pitmen F are secured to the cranks G by suitable straps, and these pitmen are secured togetherat their nether extremities by means of a cross-bar, H.
The body to be raised in the reciprocation of the pitmen is represented atI;
Acurved spring, J, is secured at one end to the frame, while the opposite end is engaged with the weight I, or with the cross-head or bar H, in such a manner that in the upward movement of the pitman said spring will assist in elevating the weight, thereby requiring a balance-wheel, K, of only suflicient size to store power enough to carry the cranks past the centers.
\Vhat I claim as my inventiomand desire to secure by Letters Patent, is
' The combination of the spring J, the pitman F,: cross-head H, and weight I, when constructed, ar-
ranged, and operated substantially as described and shown, for the purposes set forth.
ABRAM SHEAR.
