STEAM-ENGINE.
SPECIFICATION forming part of Letters Patent No. 722,225, dated March 10, 1903.
Application filed June 23, 1902. Serial No. 112,816. (No model.)
To (052 whom it ntcty concern:
Be it known that 1, PETER GINDT, a citizen of the United States, and a resident of Lomira, in the county of Dodge and State of Wisconsin, have invented certain new and useful Improvements in Steam-Engines; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention has for its object to provide simple, economical, and efficient reciprocative-piston engines with which to obtain a maximum of powerwith a minimum of steam, the same consisting in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.
Figures 1 and 2 of the drawings represent vertical longitudinal section views of a steamengine in accordance with my invention, these views being respectively indicated by lines 1 1 and 2 2 in the third figure. Fig. 3 of said drawings represents a plan View of the engine, partly in horizontal section.
Referring by letter to the drawings, A indicates an ordinary steam-engine cylinder having the ports thereof controlled by a slidevalve B, working in a steam-chest O, and the rod D of the piston E in the cylinder has play in guide-standards F on the engine-bed G, the continuity of said rod being interrupted by a cross-head H, that is shown inwardly of square contour except for diametrically opposite curved corners and diametrically opposite partly-round recesses, the plane of the corners being at right angles to that of the recesses. However, the inner contour of the cross-head may be of any design that will provide for crank clearance between the diametrically opposite recesses aforesaid.
The engine-shaftl has its hearings in standards J on the engine-bed, and a pair of arms K, keyed or otherwise fast on the shaft, are joined at their outer ends by a spindle Z), engaging an antifriction-roller c, interposed between said arms, these connected arms constituting the crank of the engine. Each arm K is made integral with a segmental device L within the same, and this segmental device has its play between antifriction-rollers d on studs 6 in connection with the pistonrod D in line with the curved inner corners of the cross-head H, above specified. A cam M, fast on the engine-shaft, plays between antifriction-rollersf on studs gin connection Withvertical ears of an extension N of the slide-valve rod N, this valve-rod extension being guided in standards P on the enginebed. A fly-wheel Q is also fast on the engine-shaft.
The valve-gear is timed to admit steam to the cylinder on one side or the other of the piston when the engine-crank is caught in a recess of the cross-head, said cylinder on the other side of said piston being then open to exhaust. The cross-head recessses are at right angles to the dead-center line of the en gine and the engine-crank caught in either recess is driven a quarter-revolution, after which it is traveled by momentum past a dead-center another quarter-revolution tocatch in the other cross-head recess, and so on as long as steam is supplied to said cylinder under control of valve-gear timed to-operate as above specified, the movement of said piston being intermittent and steadied and held against independent movement by the segmental devices in connection with the engine-shaft between the antifriction-roller projections'on the piston-rod studs.
While I have shown and described one form of engine-valve and suitable gear for actuating the same, some other form of valve, in connection with suitable gearing, may be substituted, and other variations of mechanical detail may be made in the engine without departure from what I seek to cover.
Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A steam-engine comprising a cylinder, a Valve operative to control the cylinder-ports, the piston in the cylinder having a rod movable in stationary guides but interrupted as to continuity by a cross-head having crank clearance therein between diametrically 0pposite recesses at right angles to the deadcenter line, the shaft having its crank within the cross-head engagea ble with each recess of same at recurrent intervals, projections on the piston-rod, segmental devices alined on the shaft with the crank and rotative between the piston-rod projections, valve-gear timed to shift the valve simultaneous with engageent movement of same, valve-gear timed to shift the valve simultaneous With engagement :5 of said crank with either cross-head recess, and a fly-wheel fast on the shaft.
In testimony that I claim the foregoing I have hereunto set my hand, at Lomira, in the county of Dodge and State of Wisconsin, in 2c the presence of two witnesses.
PETER GIN DT.
