VALVE-CONTROLLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 552,811, dated January *7, 1896.

Application filed July 23, 1895. Serial No. 556,964. (No model.)

To @ZZ whom it may con/cern.'

Be it known that I, JosErH F. BATCHELOR, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Valve-Controlling Devices, of which the following is a specification.

My invention relates to an improvement in apparatus adapted to control the operation of valves.

I have illustrated my invention in the accompanying drawings, in which like letters refer to like parts.

Figure l is a sectional view of the valve shown closed. Fig. 2 is a perspective view of the auxiliary valvestem and connections.

A is a valve-chest with supply-port a and exhaust-port u2,theval\'eseat a3 and awithin which is the valve-port CL4. This chest is also made with the aperture a5 and`a5 and port a6 leading from the main supply of pressure.

B is a cylinder, preferably made as part of the valve-chest A, of a diameter somewhat greater than the aperture a5 and a5 in the chest, the cylinder-head b' preferably secured to the cylinder B by the screws b2 and b2. The cylinder B is provided with the ports b3 and b4.

O is a cylindrical plunger, one end of Which c is adapted to fit the cylinder B as a pistonhead, and the other end c2 adapted to it the valve-seat a3 and. 0,3 as a valveehead, and arranged also to iit closely the aperture in the valve-chest o5 and a5.

c"3 is a spiral spring interposed between the head of the cylinder b' and the plunger or valve-head c, having its tension directed to maintain the valve-head seated.

c* is a valvestem secured to the valve-head c2 and passing through the valve-chest A.

D is a lever pivoted at d and engaging the valve-stem c4 with a pressure to open or unseat the valve.

E is the casing of an auxiliary valve in.

tended to control pressure to the cylinder B in the channel between the ports a and b3, in

which e' is a valvechest having a cylindrical Where it will be noted that the perforated slide-valve e4 is made with apertures e9 and c, through which the pressure may exhaust, as Will bel hereinafter described. The pistonhead e5 carries an armature es. The valvechest e has three ports, one connecting With the port a6 and one connecting with the port b3, and one, e7, leading from the valve-chest e operating as an exhaust.

eS is also an exhaust-port leading from before the piston-head e5.

F is a lever pivoted at f and engaging one end of the valve-stem e2.

elo is a spiral spring interposed between the valve-head e5 and the head of the cylinder in which it operates.

G is an electromagnet in circuit. The circuit connections are shown as fr and r2 and the battery as x3, and the means to control the circuit is indicated as m4, being a Morse key. The core of the magnet g', being extended and provided With a screw-thread, is screwed through the head of the cylinder, which is preferably formed of a non-magnetic material.

The operation of the valve and its control ling devices is as follows: Normally the valve is in the position shown in Fig. 1, the valve being retained seated by the spring c3. Vhen pressure is introduced through the port a', the position is unchanged. The pressure then lies before the valve-head c2, and also passes through the port a, auxiliary valve-chest e, and port b3 into cylinder B. It Will be noted that the pressure-surface of the plunger presented to the pressure in the cylinder Bis greater than the pressure-surface presented to the valve-head c? Therefore the valve will reinain closed or seated. The pressure-surface presented by the valve-head e3 and the pistonhead e5 in the valve-chest e' are supposed to be equal, the spiral spring interposed between the valve-head e5 and the head of the cylinder being directed to maintain the valve-head eS seated. Therefore, normally the port ofi is maintained open to admit pressure into'the cylinder B.` When it is desired toppen the valve in order to permit pressure to pass through the valve and out of the port a2, the

operation is as follows: The electric circuit is closed through the electromagnet G by the operation of the Morse key m4, whereby the said magnet is energized and the armature c is attracted to the core g against the tension of the spring interposed between the valvehead e5 and the head of the cylinder. The perforated slide-valve e4 and the valve-head c3 are thereby brought into position, where the perforated slide-valve e4 closes the port c6 and the valve-head c3 opens the port e7. The pressure then lying within the cylinder B and the auxiliary valve chest e is exhausted through the apertures in the perforated slidevalve e4 and the port c7, and the pressure lying before the valve-head c2 causes the same to open and permit pressure to pass through the main valve and out of the port a2. The valve is again closed by breaking the circuit to the magnet G by the operation of the Morse key gri, when the perforated slide-valve e* resumes its normal position and the valve-head es `is seated, as in Fig. l, thus permitting the admission of pressure to the cylinder B, when the piston c will cause the -main valve to close because of the greater pressure-surface presented by said piston.

The port b" is provided to exhaust any pressure that may escape between the packing of the plunger.

I have described the way in which l control my valve electrically. I may also control the same manually by operatin the auxiliary valve E by the pivoted lever F, or I may control the plunger C by means of the valvestem c and lever D.

I am aware that valves operating on the general principle of the one described have been made-that is to say, wherein a balanced valve has been controlled by an exhaust. I, therefore, do not intend to claim a valve operating on this general principle broadly, but only as to the combination and arrangement of parts which I have shown, by which construction and arrangement I believe that I have made a valve, with means to operate the same, which will overcome the difficulties which have heretofore been encountered in the construction and operation of such valves. I am also able, in the construction shown, to produce a more compact form of valve and controlling devices which are cheaper of construction and more efficient in operation than valves of the same class which have heretofore been constructed.

l. In a valve controlling device, the combination with a main balance valve of an auxil- I iary valve having a valve stem carrying a perforated slide valve, and a disk valve adapted to simultaneously control the supply and exhaust of pressure to one side of the main valve and means to operate said auxiliary valve. substantially as described.

2. In a valve controlling device, the combination with a main balance valve of an auxiliary valve having a valve stem carrying a perforated slide valve and a disk valve, adapted to simultaneously control the supply and exhaust of pressure to one side of the main valve. an electro-magnet in circuit, and means to control said circuit, and an armature, for said magnet secured to the auxiliary valve stem. substantially as described.

3. In a valve controlling device, the combination of a valve chest, A, and a cylinder, l. having valve seat and ports with a plunger, C. interposed between the pressure in the valve chest, and the pressure in the cylinder, said plunger presenting greater pressure surface to the pressure in the cylinder than to the pressure in the valve chest, and adapted to be seated in the valve seat, an auxiliary valve casing, E, interposed in the supply of pressure to the cylinder, said casing carrying a perforated slide valve e'* and a disk valve e3, with means to operate said valves, e4 and e3, substantially as described.

4. In a valve controlling device, the combination of a valve` chest, A, and a cylinder, B. having valve seat and ports with a plunger, C. interposed between the pressure in the valve chest and the pressure in the cylinder, said plunger presenting greater pressure surface to the pressure in the cylinder than the pressure in the valve chest, and adapt-ed to be seated in the valve seat, an auxiliary valve casing, E, interposed in the supply of pressure to the cylinder, said easing carrying a perforated slide valve e4 and a disk valve c3 secured to a valve stem e2, an electro-magnet in circuit with means to control said circuit, an armature for said magnet secured to the valve stern, c2, substantially as described.
