STEAM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 285,904, dated October 2, 1883.

Application filed July 10, was. (No model.)

T aZZ whom it may concern:

I Be itknown that I, JACOB KAISER, of Brookline, in the county of Norfolk, of the Commonwealth of Massachusetts, have invented anew and useful Improvement in Steam-Engines;

-and I do hereby declare the same to be de scribed in the following specification and represented in the accompanying drawings, of which IO Figure 1 is a top view, Fig. 2 a horizontal section, and Fig. 3 a transverse section, of a steam engine provided with my invention. Fig. 4 is a plan of the working -face of the valve D, hereinafter described. Figs. 5 and 6 are opposite side views of the valve 1).

Fig. 7 is a view of the cylinder A and the seat of the valve D thereof. Fig. 8 is a side view of the cross-head M, for connecting the valves and their red L, to be explained.

This engine has two cylinders and a single valve-chest therefor, arranged between them and containing two valves, applied to a single red, operated by one eccentric and its valverod connection. The rods of the pistons of the two cylinders have their cranks of the shaft to be driven arranged in planes at a right or an obtuse angle to each other, in order that each crank in passing a deadpoint may be assisted by the force applied by the other to revolve it.

In the drawings the two cylinders are shown at A and A, the intermediate valve-chest at B, the pistons at C and O, the slide-valves at D and D, and the valve-operating rod at L. 5 In one cylinder the piston thereof is exhibitedas having completed its inward stroke, while in the other cylinder the piston is represented at half stroke.

The shaft E to be revolved has one crank,

F, arranged in a plane at a right angle relatively to that of the other, F, the connectingrods of the two cranks and the piston-rod being shown at G and G. The eccentric for operating the valve-rod is represented at I, and its 5 valve-rod connection at K.

The passages for leading steam to and from the cylinders are shown at a and a and b and 1), those for exhaust of thesteam being represented at c and c and d and cl.

The ports of the valve D are shown at e and 6, those of the valve D being represented at f and f andg and g, the last two being joined by a passage, 9 The two valves are connected with their red L by a crosshead, M.

In Fig. 2 the steam-passage a of the cylinder A is exhibited as uncovered by the valve, in which case steam from the chest 13 will flow through the said passage a into the cylinder, the exhaust-steam passing from the cylinder through the passage (0, the port 0, and the passages c and c. At the same time steam will be flowing through the port f and the passage I) into the other cylinder, the exhauststeam of which will be escaping by the passage b, port y, and the passages g", d, and d. on the piston 0 having completed its inward stroke, the piston G will be at half-stroke, and the cylinder A will take steam through the port f and the passage 1), and exhaust through the passage b, the portg, and the passages g", d, and d. On the piston C having completed its outward stroke, the cylinder A will receive steam through the passage a, and exhaust through the passage (1, port 6, and the passages c and 0. Each pistoircrank. when at a dead- 7 5 point, will be assisted past such by the other piston and its crank.

An engine having two cylinders and their pistons and a single steamchest arranged, as described, between and communicating with the two cylinders by passages, represented, and also having in the steam-chest--"*' two valves, like the valve 0, and to be operated by suitable means, will be found of service, especially for locomotives for railways; 8 5 but when the crank of each cylinder is to be assisted in passing its dead-points it becomes necessary to have the cranks arranged in planes at an angle to each other, as described, and also to have to the two cylinders valves 0 and steam -passages therefor, essentially as shown in the drawings, and as hereinbefore explained.

I am aware that an engine has been provided with two cylinders having a steam-chest 5 between, in which are placed two valves having eccentric-rods, and also that a single valve has been used within such an intervening stelmchest. 7

What I claim is- IOO The combination of the two steam-engine eccentric I, and its valve-rod conneetionK, cylinders A and A, their'pistons C and C, all being substantially and to operate as set and the connecting-rods G G thereof, with the forth.
