SPECIFICATION forming part of Letters Patent No. 353,637, dated November 30 1886.

(No model.)

To all whom, it may concern:

Beit known that We, HENRY LIKLY, CHARLES A. CARPENTER, and FRED. B. GRAVES, all of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Apparatus for Working Valves; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

Our invention relates to a novel system of mechanism for automatically and at will actuating a valve located in a fluid, liquid, or gas supply pipe or main to open or close said valve, and thereby control the flow ofthe fiuid maintained under pressure in the said supply pipe o r main.

Generally stated, the said novel and improved system compreheuds the use of three co-operating but independent and distinct sets or series of devices, each possessing novel features, and as combined forming a complete system. These sets or series of devices may be denominated, the first, the valve-operating7 mechanism, embracing the motor and connections for actuating the valve in a manner to close or open the passage for the fluid in the main or supply pipe; the second, the motor-controlling7 mechanism, comprehending the devices for settingin action the motor, and the third, the trip or releasing mechanism, which includes the necessary devices for Vreleasing the motor-controlling mechanism, said trip mechanism being arranged to operate automatically or at will, whereby the opening and closing of the valves can be effected at a distance, it desired.

In the accompanying drawings, Figure l is a perspective view showing the whole apparatus complete. Fig. 2 is a vertical sectional View through the operating cylinder or motor. Fig. 3 is an end view of the mechanism for setting the valve-operating motor in operation. Fig. 4 is a front view of the same; Fig. `5, a sectional view on the line fr @c of Fig. 4; Fig. 6, a similar view on the line y y of Fig. 4. Fig. 7 is a plan view of the electrical circuits, the manipulation of which sets the motor-operating mechanism in motion.

Similar letters of reference iu the several figures indicate the same parts.

A represents the water or gas main, and B the valve therein, which is to be operated by the apparatus about to be described.

B is the stem of the valve, connected with one end of a lever, B2, pivoted uponasuitablesupport, the other or larger end being connected by a link or rod, b', with the piston of the motor.

C is the cylinderiof the motor, consisting ot' upper cylindrical portion, C', to the upper end ot' which is secured a metal cap or casting, C2, and at the lower end is a ring or casting, C3, having the annular chamber c on its inside, and communicating with theinterior of the cylinder. These castings are secured to the cylinder in any suitable manner, preferably by screw-th reads, as shown. To the lower side ofthe casting Cis attached a cylinder, C4, open at its lower end and of an internal diameter less than the upper cylinder.

D D represent two piston-heads, provided with suitable packing, d x, on their peripheries, the former of a size to fit tightly the upper cylinder, C', and the latter the lower cylihder, C", connected by a suitable cylindrical casting, D2, abutting against them, and the whole secured together by a headed bolt, D3, passing through the heads and provided on its upper end with a nut, d, as shown. The lower end of the bolt D3 is provided with a loop or eye, to which connects the rod b', that is jointed to the lever B2.

It'desired, the lower piston maybe dispensed with and only the larger piston, D, used, asuitable piston rod being employed, passing through a stationary head at the lower side, provided with suitable stuffing-boxes, as will be readily understood; although we prefer to employ the double piston shown.

On one side of each of the castings C and C3 are hollow projections C5, communicating with the inside of the cylinder, connected by a pipe or channel, F, provided with a valve or cock, F', therein for shutting off communication between them when desired. The valve has an extended arm or lever, f, for operating it, provided with a series of perforations, f', therein, so that the leverage of the link from the valve operating mechanism can be IOO changed and regulated so as to move faster or slower or have a greater power, asdesired.

Communicating with the annular space c in the lower casting, C3, is a pipe, E, leadingl to 5 the main on the side of the valve toward the supply, and as this pipe is always open the water, gas, or other fluid will .fill the chamber C', and the under surface of the piston D being of greater area than that of the piston D' Io exposed to the action of ythe fluid, the piston will move to the upper portion of the cylinder, its normal position, and, in the arrangement shown, through the lever B2 and the links the valve B willbe closed. As soon, I5 however, as the valve F is operated by any suitable mechanism,the fluid willpass th rough the pipe F, enterv the chamber C6 above the piston D, and, by reason of the greater area of surface on the top of the latter exposedV to 2o pressure, will press said piston D downward, and operat-ing again through the links and lever will open the valve B and permit the fluid to fillthe system of pipes in the house, if the device is used in connection with a re-extinguishing apparatus. When, now, it is desired to again close the main valve, the valve F' is closed by any suitable mechanism, cutting off communication with theupper sidefof the piston D. As soon as this is done the water from the main will exert all its pressure on the under side of the piston D, and cause the 'latter to move upward again forcing the wae ter above 4it out through the waste-pipe G, communicating therewith, and closing the main valve B. This waste-pipe is of small bore and the valve will consequently close slowly; but the pipe can be made larger, if desired, and the piston caused to move faster; but we prefer to make it small, as the water will run out of it continuously while the pressure is upon the upper side ofthe piston'head and the quantity lost will be small. A cock may be provided in the pipe G, to regulate the discharge as desired, and consequently the rapidity with which the valve closes. In order to have the apparatus operate au- Y tomatically, it is of course necessary to have some mechanism for operating the valve F', and this we provide inthe shape of the arrangement shown in Fig. 4, constituting a supplemental motor mechanism, In said figure, H represents a suitable frame suppo rted, preferably, above the motor mechanism, in which is mounted a suitable shaft, H', having upon one end a crank-arm, GX. Near the other end of this shaft is a wheel, G', provided with a series ofratchet-teeth, g. Mounted loosely upon the shaft H', and adapted to rotate independently thereof, when desired, is a drum, I, having at one side a large gear-wheel, I', securedA rigidly to and preferably formed with it, and lupon the side of a disk or collar, I?, secured to the hub of the drum, is a springpawl, g', adapted to engage theV teeth g of the 65 `ratchet-wheel G' when rotated in the direction i indicated by the arrow-in Fig. 6. Above the shaft H', parallel therewith, is a shaft, J, hav

ing a small gear or pinion, J2, meshing with the gear-wheel I and adapted to be rotated thereby, and having also a ratchet-wheel, J3, provided withv teeth j, corresponding to the one on the wheel G of the shaft H'. Also mounted loosely upon this shaft J isalarger gear, K, provided with a spring-pawl, k, co-

operating with the teeth j on the wheel J5, so-

as to permit of the independent rotation of the wheel J3 in one direction, but carrying the wheel K with it when rotated in the opposite direction.

L represents still another shaft,parallel with the former ones, and carrying a gear, L', meshing with the wheel'K. ShaftL on its end has a large gear-wheel, L2, which `meshes with a small gear, L3, on a fan-shaft, L4, which carries a fanV or regulator, M. Now, it will be seen that when the drum I is rotated in the direction of the arrow in- Fig. 6 by any suit- ,able mechanism, l'the motion will' be transmitted through the gear I', pinion J2, shaft J, ratchet-wheel J3, pawl 7c, gears K, gear L',

lshaft L, gear L2, shaft L4 to fan M, which latter, by reason of its large surface and the resistance which it encounters in rotation, will cause an even and regular motion of the mechanism. The drum, when rotated also through' pawl g' and ratchet-wheel G', rotates the shaft H in the .direction indicated by the arrow, Fig. 6. The crank `GX upon the end of the shaft H is connected with the handle or operating-leverf of the valve F of the motor by a pitman or connecting-rod, X, the lower end p of said pitman being adapted to engage with one or the other of' the perforationsf' of said lever f. The crank and valve-lever are sopositioned relatively that when the crankI is in one position-say elevated-the valve F will be closed, and the fluid, operating upon the lower side of the piston D only, will keep the piston raised and the main valve closed; but when the shaft has made a half-revolution and the crank is at its lowest position the lever- 'arm f will be depressed and the valve F opened, permitting the fluid to pass to the up- IIO per side of the piston D, depress it, and open 6, vas the weight falls, at the same time rotatingv the shaft H and the escapement mechanism. v

As stated above, the end is wrappedseveral I times around the drum and will consequently cause as many revolutions of the latter as there are convolutions before running down. In

order to provide for-rewinding the cord uponl the drum and elevating the weight, wehave", provided the arrangementof ratchet-wheels and pawls described. The end of .the shaft J is squared at j?, for the application of a crank or handle, so that it may be rotated in a direction opposite to its normal movement, to wind up the weight when desired, the pinion J2, which meshes with the large gear I', transmitting motion to the drum, and the pawl g slipping over the teeth g and permitting the movement independent of the shaft H. The pawl on the wheel K also slips by the teeth on the gear J 3, and does not transmit the motion to the escapement mechanism and fan when the winding operation takes place.V

It is necessary to prevent the continuous operation of the escapement mechanism and shaft H', and this we accomplish by a longitudinal rod, N, sliding in suitable ways in the frame and adapted to project into the path traversed by the wings of the fan, and to be withdrawn either by hand or automatically by means of mechanism which we will now proceed to describe.

At one side of the frame -H is secured an electro-magnet, O, having an armature, O', secured to one arm of a bell-crank lever, l?, pivoted to the frame, the other arm of which is connected with the rod N. The armature is held elevated away from the magnet by means of an adj ustable tension device, as shown, consisting of a spring, q, secured at one end to the armature-lever, and at the other to a threaded rod, q', passing through a bracket,

and provided with an adjustable set-nut, q2,

by screwing which up and down the desired Y tension can be secured. The upper end of the bell-crank lever moves in suitable guides, and at its outer side abuts against a screw, qt, adapted to be adjusted in or out so as to regulate the throw of the arm and the distance the armature is held from the magnet when the latter is energized and the armature drawn down. The spring, it will be seen, keeps the rod N projected and in engagement with the fan M and the mechanism from operation. Upon the side of the frame H is mounted a plate, Q, of insulating material, preferably hard rubber, and through it one end of the shaft H projects, and has a disk, R, of insulating material, preferably hard rubber, mounted thereon, and this disk has a notch, r, in its periphery. y

- S S represent two springs, of metal, secured upon the plate Q, one on eaclrside of the disk R, and having projectionsss', substantially in line with the center of the disk and in contact with the periphery thereof. The tendency of the springs is to approach eachother, and they are held separated only by the disk R, with their projections s s in contact therewith, while,

their lower ends project between the arms of a yoke, T', in which are secured screws t t', the yoke being also fastened to the plate Q. When the projection of either of the springs is in the notch of the disk, the end of that particular spring does not touch the screws t or t', but at all other times both said springs abut against the said screws t t and maintain electrical contact therewith.

Mounted upon the plate Q are three binding-posts, l, 2, and 3, with which the necessary electrical connections are made with the battery and circuit manipulating devices. The posts l and 3 are connected by suitable wires on the under side of the plate with the springs S S', respectively, while the central post, 2, is connected to the yoke T, as shown. From the binding-post 2 a wire, u, runs to one of the coils of the magnet O, and from the other coil a wire, u', runs to one 7terminal of a battery, U, located. at any suitable distance from the device. From the other terminal of the battery a wire, u2, runs to the binding-post 3, but between them is located a suitable circuit making or breaking device, preferably a thermostat, V, adapted in the apparatus, as shown, to complete the circuit upon the application of heat. The .binding-post 1 is connected by a wire, t, to the side ofthe battery, from which the wire ai extends, and interposed in this circuit is a circuit making and breaking key, WV, which is normally open, but is adapted to be closed by hand when desired.

The battery employed is some open-circuit battery-such as Leclanch or similar makesand may consist of any desired number of cells, preferably two or more, so that nthere will be no failure to work by reason of insufticient battery power to operate the electromagnet.

lIhe lower ends of the springs S should be faced with platinum or similar metal, so as to insure a good contact with the screws or points t t', and the latter may be similarly provided, if desired.

The thermostat is to be located at the point where the danger from re is greatest, and, if desired, several of them may be employed placed in parallel circuits, as shown in dotted lines in Fig. 7; or a key may be used operated by hand to close this circuit when desired.

The vwheel or disk R onthe shaft H is so positioned relative to the crank and supplemental motor-valve F as that when the crank is elevated and the valve closed projections s on the spring connected with the circuit c, containing thekey w, will rest within the notch o* in the disk R, breaking the connection between the lower end of the spring and the screw t on the yoke. The projection s on the spring S', however, will be in contact with the periphery of the disk, closing the contact between the end of the spring and the pin t on the yoke, the circuit containing the yoke, magnet,battery,` and thermostat being open only at the latter point.

Starting with the ideaathat the devices are in their normal position, as indicated-that is to say, the main valve closed, the piston elevated,the valve Fclosed, the crank G elevated, the stop-rod N in engagement with the fan, and the armature of the magnet retracted-- the operation of the device will be readily understood.

Vhen by means ot' the application of heat to the thermostat V, or the manipulation of the suitable key in its place, the circuit u is ICO IIO

IIS

closed through the magnets, the latter will be ene1gi`zed,will draw down the armature,with draw the stop-rod N, and permitl the escapement mechanism to be operated by the cord to which the weightis attachedunwinding from the drum I. As this drum rotates, its motion being governed and regulated by the escapement mechanism and fan, the crank will move slowly down, opening thevalve F through the connecting-rod and permitting ,the liquid to' pass from the main and underside of the piston'to'the upper side, causing the piston ,to descend and open the main valve,and, if the device is used to turn in the water in a fire-extinguishing system, permitting it to flow-to the placewhere the tire is located. Meanwhile the disk'R isv rotating and the projection s on the spring S has moved out of the notch on its periphery and makes contact with the screw .or stop thus leaving the circuit containing this spring S, yoke, electro-magnet,

' and battery broken only at the contact-key or in and breaks vthe connection between springpush-button W. When the crank has made just a half-revolution and is at its lowest point with the valve F fully open, the notch r is in line with'the projection s', which then drops S and the contact t, opening the circuit containing the magnets, releasing the armature of the latter, and allowing the stop -rod N to re-engage the fan, bringing the entire mechanism to a stand still,with the pressure of the fluid on the top of the'piston and the main valve open. lt', now, it is desired to close the main valve, it is only necessary to press the key or button W' and hold it down for a few moments, closing the circuit through the mag-l nets and-battery, energizing the latter, drawing down the armature, and withdrawing the stop-rod from engagement with the fan. The mechanism will continue to rotate while the circuit is closed until the crank Gr has made a half-revolution and is again in elevated position, with the valve F' closed, the pressure from the main shut off from the upper side of the piston, and the piston raised, shutting the main valve. As soon as this position is reached, the notch in the disk is in line with the projection s, which drops into it, and the lowerl end of the spring breaks contact with the stop t, opening the circuit and allowing the spring q to retract the armature andthrow i the rod into engagement with thefan, stop- 4ping the mechanism 'and leaving itin normal position to be again operated in thesame manner as before.

The advantages of the invention described t above will be obvious., as a ready neans is v electrical devices, because the valves may be operated from a greater distance, and the mech- .to get out of order.

ani'sm employed `is simpler and not so liable By the employment of athermostatic device for opening the main valve we are enabled to place a number ofv them in parallel circuits in different parts of a building, each connected to a local branch ot' a main, and adapted when operated by re to open the valve and per: mit the water to ow to the place ofcontlagration and extinguish the lire; and the particular 'advantage that our apparatus possesses over others of its class is that itprovides for the turning off of the water by ameans as simple, and at the same time as reliable, as the turning-on mechanism, merely by the pressin pressure on opposite sides and controllingY by its position the valve in the main, the side.v
