ALLEN T. MILLER, OF DAYTON, OHIO, ASSIGNOR TO KUIINS BROTHERS, OF SAME PLACE.
VALVE FOR MOTORS.
SPECIFICATION forming part of Letters Patent No. 545,868, dated August 27, 1895. Application filed March 21,1895. Serial No.542,669. (No model.)
To all whom it may concern: represents a similar port on the opposite side lie it known that I, ALLEN T. MILLER, reof the valve G. siding at Dayton, in the county ofMontgom- H represents the auxiliary valve gained on cry and State of Ohio, have invented certain the piston-neck h and provided with two 5 5 new and useful Improvements in Valves for seats which cover and uncover, respectively,
Motors, of which the following is a specificaports m m which ports are to admit pressure tion. medium into the cylinder E for moving the My invention relates to valves for motors; duplex piston D D in the proper direction, and it consists in the construction and combiaccording to the throw of the auxiliary valve. 60
I to nation of parts as hereinafter described and Said auxiliary valve is provided with a tripclaimed. ping device constructed as follows:
The several features of my invention will I represents a shaft reciprocating in the be more fully set forth in the description of hearing-box J and likewise jonrnaled in the the accompanying drawings, making a part stuffing-box J in one of the cylinder-heads 65 of this specification, in which K. Said shaft is provided with a finger L,

Fig. 2 top of the valve H and engages with the is a central crosssection on line m m, Fig. 1. flanges at either end. Said shaft I is oper- Fig. 3 is a bottom plan view of the main ated by the rock-lever H, which is operated 7o valve. Fig. 4 is a top plan view of the same. by the piston-rod O in the following manner:
Fig. 5 is an enlarged top plan view of the 70 represents a disk keyed upon said pistonauxiliary valve. Fig. 6 is an enlarged bottom rod and adapted to engage at each end of the plan view of the same. Fig. 7is aperspective stroke with the puppets p 19 secured to the .view of the tripping-finger and shaft. Fig. rod P, which is journaled in the brackets r. 7 5
Sis a modified form of main valve. The rock-lever M is pivoted to the boss of A represents the cylinder of the motor; B, the puppet p, and as the piston-rod C recipthe piston operated in said cylinder; 0, the rocates it strikes the said puppets alternately piston-rod. and throws the rock-lever M, which reciproa represents one of the supply-ports; a, the cates the shaft I which carries the finger L, 8:)

As shown in Fig. 1, ternately with ports a a, voiding water or the port m is open. The force of the pressother pressure medium into the chamber 0. ure medium which drives the main piston 85 5 D D represent the duplex piston reciproholds the duplex piston D D in the position eating in the cylinder E. F represents the shown. Said medium is supplied through supply-pipe tapping said cylinder. the port a, thence. through port or onto the G represents the main valve, provided with piston B, which will propel it forward. The cut-off sections adapted to respectively cover valves remain in this position until the disk 90 and uncover the portsaa. cl representsadis- K has struck the puppet p, which will throw charge-port connecting either of said ports the auxiliary valve in the opposite direction, with the exhaust-port I). Said valve is of closing port m and uncovering portm', which curved form, fitting the face of the cylinder will admit the medium of force to the duplex E. Said valve is provided with an annular piston D, which will force the said piston 95 flange 'i, fitting and seating in the tubular hack in the cylinder E, carrying with it the flange 51', formed on the shank or neck 77. of the main Valve G, which covers port a, and adpis'ton D. mitting the medium through the port 0. onto 2 represents a port formed outside of the the opposite face of the piston for driving flange j and receiving its pressure'supply the motor in the reverse direction. The ex- 10a from the inlet F through the passages e behaust is alternately through the supply-ports tween the cylinder walls and the neck 77.. e and through the port cl of the main valve and port I) in the cylinder to exhaust-chamber'c. The exhaust from the cylinder E, when the piston D D is thrown, is through the ports m m alternately with the port at of the auxiliary valve, thence by port 0, which communicates with the port d of the main valve, and thence with the exhaust-chamber. It will be observed that the neck of the piston D D carries the main valve and piston D D, reciprocates in the cylinder E, and sustains the thrusts and wear caused by the change of the stroke. The main and auxiliary valves, it will be observed, are practically balanced and may be moved easily. The exhaust ports and passages are made so as to cushion the movement of the piston by the resistance of the exhaust through the passages.
In the modification shown in Fig. 8 the main valve is provided with an annular stein tseating on the annular boss 7.) on the neck of the piston D D, which holds the main valve firmly in position laterally but yet allows it to drop down as it wears away, so as to keep its contact with the seat, and the pressure being sufficient to hold it in its seat. Likewise the auxiliary valve H, while being practically balanced, has a slight excess of pressure on its top side to hold it to its seat.
It will be observed that the ends of the duplex piston D D are connected by a neck or shank, around which the pressure medium passes, to supply the ports Ct to and m m, respectively. The said piston has its bearingsupport. in cylinder E and but little Wear is brought upon the main and cut-oft" valves, While the piston D D is practically balanced in the cylinder E.
I claim The combination with a motor cylinder and its ports and piston, the auxiliary cylinder E, and the duplex piston D D having its ends connected by a neck It provided on the under side with an annular flange, of the main valve G having an annular flange engaged with the corresponding flange of the said piston neck and provided with a central discharge port and with ports 6 e at its ends, and the auxiliary valve H seated upon the upper side of the piston neck 71., substantially as described.
In testimony whereof I have hereunto set my hand.
ALLEN T. MILLER.
