UNITED STATES PATENT OFFICE.
WILLIAM L IVINGSTONE, OF NEW YORK, N. Y., ASSIGNOR TO JOHN ROAOH, OF SAME PLACE.
STEAM-PU MP.
Specification forming part of Letters Patent No. 103,756, dated May 3l, 1870.
To all whom it may concern Beit known that I, WILLIAM LrvrNGsToNE, of the city and State of New York, have invented an Improvement in Steam Pumps or Engines; and the following is declared to be a correct description thereof.
This invention is for a direct-acting steam pump or engine, whereby the movements are made more reliable than heretofore.
The valves of the pump are made by eXpansive rings within the cylinder, actuated by the piston, to cover or uncover the respective ports at the ends of the stroke.
rIhe steanrcylinder. is made with a hollowr piston-rod that slides over a grooved spindle, and a pin working in said groove gives rotation to the spindle to actuate the valves.
By this construction and arrangement the parts are very compact and not liable to get might be used if preferred, and the rotary motion that actuates the valve is obtained without the use of a crank and shaft.
In the drawing, Figure l is an elevation of the pump and engine. Fig. 2 is avertical section; and Figs. 3 are elevations, in larger size, of the spindle. Fig. 4 is an elevation; and Fig. 5, a section of part of the steam-cylinder, illustrating the manner in which a fly-wheel can be used. Figs. 6 show the water-valves attached. Fig. 7 is -the eccentric and strap for the steam-valve detached and in enlarged size. Fig. 8 is a vertical section of the steamcylinder, showing a modification of the valves and ports; and Fig. 9 is a similar view at right angles to Fig. 8.
The steam-cylinder a is connected to the water-cylinder b by the frame-work c.
The steam-piston d and water-piston e are united by the piston-rod f, that is partially or entirely tubular and passes through the stuffing-boxes 2 2. The cylinders a and b and framework o may be in one casting, as shown,
pa-ss either through the water-fwa-ys, as shown, or through holes in the piston c; and these rings are at such distance apart, and the ports 3 3 4 4 so located relatively to each other, that, as the piston completes its stroke in either direction, the rings are moved with it, uncovering the eduction-port at the opposite end of the cylinder and closing the inductionport at that end, and simultaneously uncoveringthe induction-port near the piston and closing the eduction-port, so that the parts are in position for the reverse movement of the piston c.
The spindle n is mounted centrally of the steam-cylinder, so that the piston-rod f' slides over it, and this spindle is held in place by a nut or head, 6, above an arm, 7, so that the spindle is free to be rotated.
A rod, S, secured at both ends by the cylinA der-heads, serves as a guide to prevent the pistons revolving or partially turning upon or with the piston-rod.
In the spindle a is a compound twisted or inclined groove, o, that makes a half-turn in passing the length of the pistons stroke, and then another half-turn in coming back to the point of beginning, so that a pin or a stud and roller, s, upon the piston d communicates to the spindle none revolution each complete stroke. The rotation of this spindle u gives motion to the steam-valves, and, if desired, this spindle n may be prolonged through the cylinder-head and receive a y-wheel, m, to equalize the movement; but I find that if one side ofthe groove ois inclined to the extreme end, so that the pin s continues to actagainst the same and turn the spindle u, and if the other portion of the groove is nearly straight, as at 10, the pin s will be sure to pass upon the proper side of the point l1, between the grooves, and thereby insure the rotation of the spindle, even if the piston may vary slightly in the length of stroke.
The valves I employ are circular or pistonvalves v c, connected together and contained in the cylindrical steam-chest p.
.q q are the steam-inlet ports from the steampipe; 12 and 13, the ports to the cylinder, and l5 the exhaust-pipe.
These piston-valves operate in the well known manner for giving the steam and ala lowing the exhaust, and, being balanced by the pressure acting in opposite directions, move With very little friction.
The eccentric w is employed upon the spindle n for moving these valves.
In Figs. l and 2 the eccentric w is Within lthe steam-cylinder, and the rod x passes out through a stufingbox and connects to the lever t of the valve-rod y, so that the said valves are moved thereby. Said leccentric u and rod a: may, however, be outside the cylinder, as in Figs. et an d 5, or, if the steam-chest is at the end of cylinder a, as in Figs. S and 9, the eccentric w may be Within the stea1nchest and act between the piston-valves c c.
A cam may be substituted for the eccentric w, and shaped so as to give any desired movement, to open the ports more or less rapidly.
