Steam-Engine Reversing-Gear

OF NEWARK, NEW JERSEY

Specification forming part of Letters Patent No. 223,632, dated January 20, 1880. Application filed May 28, 1879

TO ALL WHOM IT MAY CONCERN:

Be it known that I, William Baxter, of the city of Newark, in 'the county of Essex and State of New Jersey, have invented a new and useful Improvement in Steam Engine Reversing-Gears, which improvement is fully described in the following specification.

My invention relates to an improvement in steam engine reversing gears and cut offs for reciprocating engines; and it consists in a novel mode of securing a shifting eccentric upon the crank shaft of the engine, and in a peculiar device for shifting the eccentric while the engine is in motion, to reverse the motion of the engine or alter the center of cutting off, and in setting the center of the eccentric in a special relation to the shaft and the engine crank.

Figure 1 of the drawings is a side view of a crank shaft provided with my improved eccentric. Fig. 2 is a plan of the shaft with the traveler and clutch ring. Fig. 3 is an end view of the crank shaft, showing the traveler fitted thereon and the eccentric in its central position. Fig. 4 is a similar view, showing the eccentric at one extreme position; and Fig. 5 is a detached view of collar c.
