PISTON FOR LOCOMOTEVE AND OTHER ENGINES.
SPECIFICATION forming part of Letters Patent No. 307,709, dated November 4,1884.
Application inea August 7, 1834. (No man.)
To @ZZ whom t may concern:
Be it known that I, EDWARD P. CowLns, of Vequiock, in the county of Brown, and in the State of Visconsin, have invented certain new and useful Improvements in Pistons for Locomotive and other Engines; and I do hereby declare that the following is a full, clear7 and exact description thereof.
My invention relates to improvements in pistons especiallyr designed for use in locomotives, and will be fullydescribed hereinafter.
In the drawings, Figure l is a vertical longitudinal section of an engine cylinder and piston, showing the construction of my improved compensating device; and Fig. 2 is a vertical cross-section of the same. Fig. 3 is an elevation of so much of the frame and truck of a locomotive-engine as is necessary to show the location and application of my device.
In my present invention I have shown my device as applied to a locomotive-engine such as is shown in my Patent No. 303,491, dated August 12, 1884, and I have shown in Fig. 3 only so much of a locomotive as is necessary. p
A shows a part of the engine-frame, and B B the trucks, each of which has six wheels, the front ones, C', and the rear ones, G2, of which are fastened to ordinary axles, c o, running in suitable bearings attached to the truck-V frame.
E is the engine-cylinder, located between the rear wheels, G2, of the front truck, B, and the front wheels, C', of the rear truck, B.
Each of the trucks B B has the crank of its shaft directly connected by the rod a to the piston of the engine-cylinder. This latter is suitably bolted to the under side of the frame A, midway between the trucks B B. The piston-rod y extends through both heads E E of the cylinder, and each end of said rod y carries the cross-head s,working in the guiderod s', suitably mounted in the under side of the engine-frame A. The front end of the piston is thus coupled with the front truck, B,while the rear end is coupled with the hind or rear truck, B, both ends working obviously together in the same vertical and horizontal planes.
The object of my invention is, primarily,
to provide a compensating device for the connections between an engine-piston and the drive-wheels of a locomotive-engine; but it is also applicable wherever unequal strains are produced; and I will next describe the construction of my piston, especially designed to accomplish the said result. This piston is composed of two parts, each of which has an end-play in the piston-head c. Secured to the inner end of each portion is ahub, e', and these hubs are so formed that the outer end of one overlaps the outer end of the other. In each of the overlapping ends of the hubs a slot is formed to receive a block, e', and these blocks are connected by means of the pins f f to the arms of arocker, g', that has its bearings in the piston-head z. The hubs c z are cut and turned to lit each other nicely and the boring in the piston-head, in order to prevent their springing and to keep them perfectly in line. Owing to this construction, it is obvious that the power applied to the piston -head c will be equally distributed through the rocker g to the respective portions of the piston. This latter will thus be left absolutely free to adjust itself to any variation in the distance between the crossheads and the cranks of the driving-shafts, owing to the angularity of the connecting-rods at the lower and higher points of their strokes.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isg l. A piston composed of two parts, each of which is freely connected to one end of a lever centrally fulcrunied in the piston-head, whereby the power applied to the said pistonhead is equally transmitted to each of the said parts, allowing them at the same time to adjust themselves to any variation produced in the distance between the cross-heads as the higher or lower points of the drivingshaft cranks are neared, substantially as set forth.
2. A piston composed of two parts, each of which has a play in the piston-head, wherein a hub fastened onto the end of one of said parts and shaped so as to overlap av similarlyshaped hub fastened onto the end of the other part is connected to the latter by means of a rocker working in the said pistonl1ead,wherc bythe piston-rods are adapted to adj ust thein- In testimony that I claim the foregoing I selves to the varying distance between the have hereunto set my hand, at Wequioek,i n
,cross-heads as the higher or lower points of the county of Brown and State of Wisconsin.
the revolution of the driving-shaft cranks are in the presence of two witnesses. 5 neared, substantially as set forth. 3. The piston having the head z, the hubs EDI/VARI) I?.
