VALVE-GEAR FOR STEAM-ENGINES.
SPECIFICATION forming part of Letters Patent No. 307,898,:1ated November 11, 1884.
Application filed June 5, 1384. (No model.)
I 1'0 all whom it Duty concern:
. is pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 represents a longitudinal vertical section of a steam-pump provided with my Valve-gear. Fig. 2 is a plan or top view of the valve-stem detached. Fig. 3 is a transverse vertical section in the plane 00 m, Fig. 1. Fig. 4 is a transverse section of the valve and the valve-seat on a larger scale than the previous figures, the plane of section being indicated by the line y 9, Fig. Fig. 4* is a transverse section of the valve on the line 31* 3 of Fig. 5. Fig. 5 is a plan view of the valve detached. Fig. 6 is a transverse vertical section of the steam-pump in the plane Z Z, Fig. 1. Fig. 7 is a side view of one of the pump-valves on a larger scale than the previous figures. the same.
Similar letters indicate corresponding parts.
In the drawings, the letter A designates a steam-cylinder, in which works the steampiston B, and from this piston extends the pistonrod 0 through a stuffing-box in one of the cylinder-heads, the same as in any ordi nary steam-engine.
I have shown the pump-cylinder I provided with a lining, 8, having alongitudinal slot and confined in place by bolts the heads of which fit the slots; but such features are not herein claimed, as they constitute the subject-matter of a separate application filed by me of even date herewith, Serial No. 133,960. The steamvalve D is tubular, openat both ends, and provided with:a transverse partition, a, at about the middle of its length. In one end of the tubular valve is firmly secured a bridge or traverse, b, in which is fastened the valve-rod Fig. Sis a plan or top view of E. The valve is provided on the opposite sides of the partition a with a series of small ports, 0 0 (1 d, which are arrangedin relation to each other as shown in Figs. 1, 4., 4*, and 5. By referring to these figuresit will be seen that the ports 0 and c are in the upper part of the valve, while the ports (I d are in the lower part of the same. The solid'spaces between the ports 0 are in line with the ports 0, or vice versa, Fig. 5, and the solid spaces between the ports 0 0", respectively, are diametrically opposite to the ports (Z (2", respectively. (See Figs. 1 and 4.) The valve is fitted into a tubular valve-seat, F, Figs. 1 and 4., which is firmly secured in the valve-chamber G. This seat is provided with steanrports 0 0, and with exhaust-ports d d,which are so arranged in relation to the ports 0 0 (1 d of the valve that when the valve is turned to the position shown in Figs. 1 and 4 the ports 0 register with the ports a, and the ports d register with the port (1", while the ports 0 and cl are closed. In this position steam passes from the steampipe H through the ports 0 0 and channel 6 into oneend of the steam-cylinder A,while the steam from the opposite end of the steam-cylinder passes through channel f and ports cl d to the exhaust-pipe By imparting to the valve a very short revolving motion in its seat, the ports 0 61 are closed and the changed, so that it passes from the steam-pipe H through port 0 and channel f into the cylinder, while it exhausts through channel 6, port (1, and exhaustpipe g. The valve-rod E extends through a box, h, in one end of the valve-chamber, and it is provided with a cone valve, 1', which is forced by a spring, j, into a seat formed in the mouth of the box h, so as to prevent the escape of steam. The outer end of rod E fits a socket, 7;, which is formed on or secured to the head of the pump-cylinder I, and which contains the spring j above referred to. On the valve-rod are mounted two tappets, J J, and on the piston-rodCis firmly secured an arm, K, on the upper end of which are formed inclines Z Z, which act upon the tappetsJ J 'andimpart to the valve-rodEandvalve D the revolving motion required for changing the steam. I11 the position shown in Fig. 1 the pistonrod moves in the direction of the ports 0" d are. opened, and the steam is arrow marked thereon, and when the incline Z strikes the tappet J the ports 0 cZ are closed and the ports 0" d are opened. On the return-stroke the incline Z acts upon the tappet J, and the ports are restored to the position shown in Fig. 1. The tappets J J are provided with lugs mm, which contain the screws 02 n, so that by turning these screws in or out the time when the valve is changed can be ac commodated to the stroke of the piston. This effect is due to the fact that if the tips of the screws n n are made to project a greater distance beyond theinner surfaces of the tappets J J the inclines ZZ act upon them at an earlier part of the stroke of the piston B, and vice versa. The adj ustin g-screws n n are provided with lock-nuts, by means of which they can be locked in the required position.
From this description it will be seen that a very short revolving motion of the valve is suificient to change the steam, and that by making the tappets J J adjustable the motion imparted to the valve can be regulated with the greatest ease and facility to conform to the stroke of the piston.
Vhat I claim as new, and desire to secure by Letters Patent, is-
1. The piston-rod 0, having the rigid arni K, provided at its upper end with'the attached inclines Z Z, which travel with the arm in its reciprocations, in combination with the valverod E, having the tappets J J, the tubular valve D, having the partition a, and ports a d c d on opposite sides of the partition, and the valve-seat having the ports 0 d 0" d, substantially as described.
2. The piston-rod 0, having the rigid arm K, provided at its upper endwith attached inclines Z Z, which travel with the arm in its reciprocations, in combination with the valve rod E, having the tappets J J, the adj ustingscrews n 12, passing through the tappets, re-
spectively, to be acted upon by the inclines, the tubular valve D, having the partition a, and ports 0 d a" d", and the valve seat having the ports 0 (Z 0" d", substantially as described.
In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
THOMAS BARBER.
