STEAM-ACTUATED VALVE.

SPECIFICATION forming part of Letters Patent No. 552,081, dated December 24, 1895.

Application filed March 20, 1895. Serial No. 542,463. (No model.)

To all whom it may concern.- 15. Extending from the steam-chamber Be it known that I, GEORGE H. WILLIAMS, through the steam-chest to the cylinder are of Marion, county of Grant, and State of Inthe steam-ports 16, and extending from the diana, have invented a certain new and usecylinder are the exhaust-ports 1'7, which are 5 ful Steam-Actuated Valve; and I do hereby first vertical andthen horizontal, as seen in declare that the following is a full, clear, and Fig. 6, leading out at 18. exact description thereof, reference being had Between the steam-chamber 15 and the va to the accompanying drawings, in which like

rious valves

9, 11 and 12 and the cylinder are numerals refer to like parts. a number of passage-ways for the passage of 10 My invention relates to a steam-actuated steam, whereby it is enabled to actuate such valve which in construction is wholly indevalves sem'ate'm and prevent centering. These pendent of the piston andis so arranged that it passage-ways in one end of the steam chest will admit steam to the cylinder and exhaust it and cylinder are the same as those in the other and avoid centering the piston. I use a series end thereof and they are all made straight, 6 5 t 5 of piston-valves so provided with passage in order that the device may be economically ways from each other and the steam chamconstructed. By placing the steam-chest in her and cylinder that they and the piston will a drill-press and by using jigs it is seen that coact successively on each other and thus although the number of passage-ways may prevent the centering of the piston. The conseem great they may be very quickly made. 70, 2o struction is such also that it is very economi- To register with these passage-ways, as well cal and of small dimensions. I have used it as the steam and exhaust ports, the valve 9 in connection withasteam-pump;butit can be is provided with the annular grooves 19, the used with any other steam-engine. The full valve 11 with the annular grooves 20 and the nature of its construction and mode of opervalve 12 with the grooves 21. The arrange- 2 5 ation will be understood from the accompanyment of these passage-ways and the operation ing drawings and the description following. of the device will be understood from the fol- Figure 1 is a plan view of the steam-chest lowing explanation: Suppose the piston is at with the cover and gasket removed. Figs. the forward end of its stroke, as shown in 2, 3, 4 and 5 are sections on the lines A A, Figs. 2 and 3, and the valves are in the posi- 8o 0 B B, O O, and D D, respectively, of Fig. 1. tions shown. The steam entering'the cylin- Fig. 6 is a bottom view of the steam-chest der passes through the annular groove 20 in cover, showing the exhaust-ports.

valve

12 and 10 are the same as Figs. 2 and 3, excepting opens the passage-way 23, allowing the steam that they show the position of the valves to enter from the steam-chamber 15 through when the piston is at the opposite end of its the passage-

ways

24, 25 and 26 into the end I stroke. of the main valvechamber 10, whereby it 40 I show here an ordinary cylinder 1 and pisdrives the main valve 9 to the position shown ton 2. On the cylinder is mounted a steamin Fig. 2, at the same time such auxiliary valve chest 3 havinga cover 4, to which is connected 12 opening the passage-way at the other end asteam-pipe 5. Betweenthe cover and steamof the steam-chest to exhaust the other end chest is a metal gasket 6. The parts are conof the valve-chamber 10. WVhen the valve 9 45 nected in the usual way by bolts 7 through is moved to the position shown in Fig. 2, the holes 8. Within the steam-chest I provide a annular groove in one end registers with the main piston-valve 9 moving in its valve-chamsteam-port 16 and at the other end with the her 10, and also two smaller auxiliary pistonexhaust-port 17, allowing the steam to be fed

valves and the gasket 6 is a steam-chamber So far the auxiliary valve 11 has not been acted upon; but as soon as steam is introduced to drive the piston back from the position it occupies in Fig. 2 steam passes through the passage-way 27, as shown in Fig. 3, that leads into the end of the valve-chamber 13 behind the valve 11, whereby it is driven into the position shown in Fig. 9, and the annular groove in the valve 11 registers with the passageway 28, through which steam is exhausted from the end of the valve-chamber 14, as shown in Figs. 3, 4 and 8, allowing the valve 12 to be moved back. At the same time it opens the passage-way 22 at the other end of the steam-chest, allowing the steam to enter the other end of the valve-chamber 14 behind the valve 12. From this point on the process which has heretofore been described is repeated as the piston moves backward and forward.

To recapitulate the passage-ways for conducting live steam: There is a passage-way from the cylinder to the end of the chamber 14 that passes through the auxiliary valve 11, a second passage-way between the steamchamber 15 and the main valve-chamber 11 going through the auxiliary valve 12. There is the main steam-port from the steam-chamber 15 through the main valve to the cylinder, and, fourth, a passage-way from the cylinder to the end of the valve-chamber 13.

The following passageways and ports exhaust the steam: First, there is an exhaust passage-way 28 from the end of the chamber 14 that goes through the valve 11. In the sec 0nd place, there is an exhaust passage-Way from the main valve-chamber 10 through the passage-ways 26, 25, 30 and 31 and going through the valve 12. Third, there is a main exhaust-port 17 from the cylinder that goes through the main valve 9. In the fourth place, there is the exhaust passage-way 27 from the end of the chamber 13 into the cylinder. This valve mechanism may be entirely independent of the cylinder and I have used it in that What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination with a steam cylinder and piston, of a steam actuated valve mechanism comprising a steam chest provided with chambers or secondary cylinders extending parallel with the main cylinder and passage ways connecting the chambers or cylinders and steam inlet, and the piston valves 9, 1.1 and 12 fitting in said chambers so as to slide therein and shut off or open up the passage ways, the passage ways and valves being arranged in such order that the steam will act upon them in succession, substantially as set forth.

2. The combination with a steam cylinder and piston of a valve mechanism comprising a main piston valve and two auxiliary valves, a steam chest provided with a steam passage way leading from the cylinder through the valve 11 into the valve chamber 14, another from the steam cha1nber'15 through the valve 12 into the main valve chamber 10, another from the steam chamber 15 through the main valve 9 into the cylinder and another from the cylinder into the valve chamber 13, and an exhaust passage way from the valve chamber 14 through the valve 11 into the exhaust port 17, another from the main valve chamber 10 through the valve 12 into the steam port 17, another, the main exhaust port, from the cylinder through the main valve 9 and another from the valve chamber 13 into the cylinder, substantially as shown and described.

In witness whereof I have hereunto set my hand this 2d day of March, 1895.
