Description

SAMUEL VAN EMON. Improvement in Pitman Connections for Steam Engines.

I r 7, A /%M/M. 7y l Patented Oct. 24, U871.

a M W UNITED STATES PATENT OFFICE.

SAMUEL VAN EMON, OF OOVINGTON, KENTUCKY.

Specification forming part of Letters Patent No. 120,222, dated October 24, 1871.

i To all whom it may concern:

Be it known that I, SAMUEL VAN EMoN, of Oovington, in the county of Kenton and State of Kentucky, have invented certain Improvements in Pitmen-Oonnections for Steam-Engines, of which the following is a specification:

The nature of this invention consists of a peculiar device for connecting the pitinan to the piston-rod, designed for cheap manufacture, and adapted principally to the class of steam-engines which has a vertical cylinder above the crankshaft and pitman or side rods straddling the cyl inder.

Figure l is a front elevation, showing the connection between the pitman and piston-rod in section. Fig-J2 is a detail view of the pitmanjoint in transverse section.

The same letters of reference are employed in both figures in the designation of identical parts.

A is the cylinder of the engine; B, the crankshaft; O, the piston-rod; and I), the pitman. The piston-rod is prolonged beyond the pitmanjoint, the prolongation working in a guide, E. In order to dispense with the side rods, crosshead, and side slides usually employed in engines of this class I use the ringpitman D, which straddles the cylinder A, andlhas but two points of contact with the other parts of the engine, one on the crank-wrist and the other at the junction with thepiston-rod. The connection of the crankwrist is made by the capped journal-bearing F, and to the piston-rod by the following peculiar device: The pitlnan near its junction with the piston-rod is rectangular in cross section, the center being enlarged and circular in the plane of vibration, as shown at (1. Two trunnions or short journals also project from the sides of the pitman at this point at right angles to the plane of vibration of p the pitman, the trunnions being shown by d d. The pitman D fits between the jaws of the rectangular socket G, which is formed on the piston-rod, the gibsH H being interposed between the pitman and the ends of the socket. The gibs are constructed to fit both the trunnions and the circular center 01. The key I keeps the gibs in place and serves to take up the wear.

What I claim as my invention, and desire to secure by Letters Patent, is

The herein-described swiveling-connection for pitman and piston-rod, consisting of socket G, gibs H H, key I, and circular center d cl d, the parts being combined to operate substantially in the manner and for the purpose specified.

In testimony of which I hereunto set my hand.
