TRANSMISSION MECHANISM.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed April is. 1906. Serial No. 311.5%.

T0 at whom, it may concern.-

Be it known that I, GEORGE S. CoMsTocK, a citizen of the United States, residing at Mechanicsburg, Cumberland county, State of Pennsylvania, have invented certain new and useful Improvements in Transmission Mechanism, of which the following is a specification.

This invention relates to improvements in mechanism is provided which will run.

smoothly without undue friction after the parts are worn out of true or if imperfectly fitted when constructed.

With this and other ends in view the invention consists in the construction and arrangement of parts hereinafter described and claimed.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical section, with parts in side elevation, showing my invention as applied to a double-piston reciprocating engine. Fig. 2 is a horizontal section through the device illustrated in Fig. 1 with parts in plan. Fig. 3 is a transverse section, and Fig. 4 is a plan and part sectional view, of a modification of a part of the invention.

Referring to the drawings, Figs. 1, 2, and 3, A A are the opposing cylinders of a two- I cylinder reciprocating, engine containing the pistonsB B, connected by a suitable yoke O. Extending transversely of the engine is the rotary shaft D, suitably journaled in the engine-casing, as illustrated in Figs. 2 and 3, having the crank portion E ournaled in the block F. Said block F is also provided with a vertical journal-box adapted to receive a guide L, connected to the yoke O.

Referring to Fig. 4, the crank portion E of the shaft D is j ournaled in a block N, as above, and the block N is mounted to reciprocate in a hollow slotted guide M, the slots in said guide being sufficiently wide to permit a relative oscillatory movement in a horizontal-plane between the guide and the sliding block N. d

In both of the above embodiments of the invention it will be seen that a universal joint is established between the reciprocating and rotary members, the arrangement permitting a relative oscillatory movement on the axis G G, the axis H H, and the axis of the crank E, and thus the parts readily adapt themselves to the easiest working positions in the operation of the engine.

Obviously this invention is not limited to use in combination with an engine of the class above described, but is equally applicable to many other machines, as pumps, aircompressors, steam-engines, &c.

I claim 1. The combination with a reciprocating piston and a rotary crank-shaft, of a guide on said piston, and a block mounted to reciprocate on said guide and to oscillate in a transverse plane, said block also j'ournaled to the crank of said shaft.

2. The combination with a reciprocating piston and a rotary crank-shaft, of a yoke extending from said piston, a guide mounted in said yoke, and a block journaled to the crank of said shaft and connected to said guide for relative reciprocatory and transverse oscillatory movement.

3. The combination with two opposed reciprocating members having the same axis, of a yoke connecting said members, a guide mounted in said yoke having a cylindrical bearing-surface, a block slidably connected to said guide, and a crank-shaft with which said block engages.
