OUT-OFF MEOHANISM FOR STAND-Pipes.

SPECIFICATION forming part of Letters Patent No. 534,171, dated February 12, 1895.

Application filed February 24, 1894. Serial No. 50l,351. (No model.) x

To all. whom it may concern:

Be it known that I, ROBERT MOGOWEN, of

"Washington, in the county of Daviess and adapted to be set in operation from the pumping station or other desired point, and which willpositively serve to instantly cut oif the stand pipe from the water main, and place it in communication therewith again, as may be desired. Y

To these ends the invention consists, first, in a combined electrically and gravity operating mechanism for cutting oi the main from the stand pipe; secondly, in electro-hydraulic operating means for elevating the said cut off mechanisms to restore them to their normal position, and thirdly, in mechanically operated tripping devices adapted to be operated by the upward movement ofthe cut off means,

whereby to close off the hydraulic elevating means, and for draw-ing off the water.

My invention furtherconsists in such novel arrangement and peculiar combination of parts, all of which will hereinafter be fully described in the specification and then particularly pointed out in the claims, reference being had to the accompanying drawings, in which-- f Figure l is a side elevation of my improved out off mechanism. Figs. 2 and 2a are longitudinalvertical sections of the upper andlower portions thereof. Fig. 3 is a horizontal section ofthe same on the line 3-3 Fig. 2a. Fig. 4t is a similar view of the same on the line 4 4 Fig. 2a. Fig. 5 is a detail sectional plan View on the line 54-5 Fig.` 2a. Fig. 5a is aside View of the parts shown in Fig. l5. Fig. 6 isa plan view of one of the electro mechanical tripping devices. line 7-7 Fig. 6. Figs. 8 and 9 are detail views hereinafter specically referred to, and Fig.

10 is a sectional view of the cut olif valvehere' inafter referred to. n

Fig. 7 is a sectional view thereof on v` In the practical construction of my invention, I employ in connection with the valve or gate in the water main or the lateral leading to the stand pipe, valve closing and opening devices, which can be instantly set for automatic opera-tion from the pump station, or any other desired point, and such devices include plunger and tripping mechanism electricall y released and-adapted to close the valve by a gravity movement and to set in operation, hydraulic means, which will operate to return such plunger and tripping devices to their normal position, which return movement of such parts will set in operation supplemenn tal tripping mechanism which will serve to automaticallyV cut off the hydraulic lifting means.

Referring now t0 the accompanying drawings, A indicates the main pipe, B the stand pipe lateral and C the stand pipe, all of which may be of any ordinary arrangement. Within the section B ofthe main pipe, is disposed a gravity valve D hung on arockshaft, the outer end d of which has a lever or crank arm cl', fixedly held thereon, providedat its end witha lateral pin cl2, and on thegsaid end of such shaft is also pivoted loosely a second lever arm dxgthe front end of which has an elongated slot d3, which connects adjustably With an arm e, of the plunger or vertically movable frame presentlyY referred to, and to facilitate the lifting movement of the valve D the same may have its crank arm CZ weighted as at d* such weight being however less than the weight of the valve proper whereby such valve will drop by gravity.

As shown in Fig. 2a the valve operating arms are disposed in a trench or well hole, over which is disposed the solid base F of the operating or plunger mechanism supporting frame. This frame it will be noticed consists ofacross head f, supported on the strain rods f,f, it being fixedly'held by thetubular sleeves f2, which surround such rods and are interposed between the base and'the cross head as clearly shown in Figs. 2 and 2a. A fixed cylinderG projects centrally upward from the base. The upper end is closed by a cross plate GX which is braced kby a pair of guide rods g g at each side, `which are fiXedly-coninected with the upper cross head f as shown.

Between the guides g g is held for vertical IOO reciprocation a weighted cross bar H, to which is rigidly connected the tubular stem JX, of a piston J, which is fitted to move in the cylinder G, such stem extending normally above the cylinder` G, and is open as shown.

E indicates a sash frame, which consists of a lower transverse bar e', which passes under the base F, an upper transverse bar e2 disposed normally some distance above the cylro inder G, and the connecting or strain rods e3 es which pass down at one side of the base F and the cross plate GX,as most clearly shown in Figs. 3 and 4.

Within the tubular stem or cylinder J X is held for vertical reciprocation a piston K, on the lower end of a tubular stem KX, the upper end of which, when in its uppermost position projects above the cross headf, it being closed at such end, and provided near such end with zo a bleeding 0E cock 7c as shown. It will be noticed by reference to Fig. 2 that the stem KX passes through the upper cross bar e2 and is connected fiXedly therewith, while its upper end has a loop or hook member k2 whereby it is supported on a tripping arm L or dog, which is adapted to be electrically released in the manner presently described.

The tripping arm L is pivoted at Z' and has its long member l normally held to its locked 3o position by a bell crank lever M, the long arm m of which projects within a vertically movably weighted guide frame N, the lower cross bar 'n of which is adapted to engage such arm m, when the frame is released.

It will be noticed by reference to Fig. 2, that the frame N is normally held to an elevated or normal position by a pivoted pawl O, which in turn is held to a locked position by a pivoted armature pawl P, pivoted at p to the 4o frame PX and normally held to its locked position by the spiral spring p', its vibratory movements being limited by the adjusting screws 192102 as shown. The lower end,of the pawl P has an armature P which is operated by the electro magnet Q, the circuit Wires of which are extended and arranged in a manner presently described.

So far as described it will be readily understood, that when the magnet Q is energized, 5o as hereinafter stated, the pawlP will be drawn with its rear end inward, thereby throwing its upper end outward and disengaging the pawl O, which releases the frame N, and allows it to drop and as it drops its cross bar n. engages the bell crank lever M, and releases the trip L, such drop being limited by the stop NX, engaging a lifting bar presently referred to. As the tripper arm L is thus released the sash frame E and the tubular stem oo and piston connected therewith will drop by gravity, the impact force of which is however checked by the airdash pot formed in the cylinder JX, the cushioning or resistance force of which can be regulated by setting the bleeding ol cock 7a. As the frame drops, the arm e carries arm dX down with it and thereby frees the valve arm d and allows the valve D to drop to a closed position, where it is held by the pressure from the main pipe. Thus it will be seen that the closing operation of the valve is effected by electrically released gravity mechanism.

By providing an air cushion or dash pot devices arranged as shown, the sash frame E will be protected from a sudden jar, thereby causing a'steady closing movement of the valve D.

Having thus described the closing operation of the valve I shall now proceed to describe the means for elevating the sash frame and opening the valve.

Referring now more particularly to Fig. 4 it will be noticed that extended transversely under base F is a feed water pipe R which opens centrally into the cylinder G, and such pipe R has valved connections fr r with main feed pipe laterale S S. These valve connections, which are alike and held to operate in unison, have each an outer section provided with inlet port s (see Fig. 10) and an outlet or exhaust port si, and a main discharge si, which opens into the cylinder. Within the outer section is held a tubular valve T provided with a longitudinal slot or pointt which is adapted when shifted in one direction (indicated in full lines Fig. l0) to bring into communication, the main or feed pipe with the cylinder G, and when shifted in the other direction (see dotted lines Fig. l0) to open up communication between such cylinder and the exit or exhaust pipe section S. The ends of the valve T are projected as at T and connected centrally with oscillating levers U U, the ends of which are connected by cross arms tt u', such arms normally being disposed in the position shown in Fig. 2, in which position, the main or water feed pipes are out olf from the cylinder.

Ina guide frame V, projected up from the cross head j', are disposed electrically operated tripping devices W, which arc constructed and operated in a manner precisely similar to the electrically operated tripping devices L, M, N, O, I), and Q before referred to. Suspended from the tripper arm LX,of the devices W, is a rod X guided at its upper end in a sleeve f5, and which passes through an aperture h, in the cross bar Hand is secured at its lower end in a stem Y, having asocket y and on which is held a weight Y', and in such socket y a push pin y is held for limited movement therein, it normally resting upon the cross bar u as shown.

Z indicates a tappet adjustably secured on the rod X for a purpose presently explained.

While the electro magnets Q and QX can be set in operation by independent circuitwires and energizing magnets I prefer to employ for simplicity of operation and economy in construction, a single circuit arranged in the manner clearly shown in Fig. 1, in which A5 indicates the pumping station or other operating point. B5are energizing magnets with which in practice is connected an alarm bell;

. a5, the ground wire 'and b5 the main circuit Wire. This wire itwill be noticed connects with a metallic arm c of a length equal to the movement of the piston K, which connects with binding posts c5 c'r passed through insulated boxes in one of the guides gX g at one side, the inner ends of which have contact plates c8 c5. Similar contacts a9 a9 are secu red on the inner ends of posts d5 d5 passed through insulated boxes in the opposite guide member gx, the upper one d5, of which is connected by the wire cF, with one pole ofthe magnet Q,

while the other d5 connects by the wire d8,

with one of thepoles of the opposite magnet QX, and such magnets are joined by the wire dg, from which extends a ground Wire CZIO.- By

thus arranging the electric circuit Wires asdescribed and shown I am enabled to use a the energizer B5 be turned, the current would travel through the said upper contacts to the vmagnet Q, and thereby release the drop mechanism before referred to, which stays at its lowerrnost position, until the pump station operator has been notified that the stand pipe' can again be placed in communication with the main pipe. After the piston K has reached its lowermost position -the arm D5 will be moved in contact with the lower plates c8 and ci and thereby complete acircuit between the energizer B5 and the magnet QX. It will thus be seen that by operatingsuch energizer the magnet Q will be thereby energized to operate the tripper arm LX, to release the rod X, which falling by gravity engages the cross bar u and moves the levers U U, down to the position shown in dotted lines in Fig. 25, which movement opens up thevalvesTand allows the water from the pipes S under pressure to enter cylinder G under the piston .I to slowly raise it.

As'the cylinder J is thus raised the pistonl K and the sash frame E carried thereby are elevated, as also the crossbar H, such upward movement serving to raise the stem K into engagement with trigger arm L, which arm is placed in a locked position, by the continued rise of the bar H, which in its movement engages a lift device formed of a rod E5 having a transverseV bar F5 at its upper end,

which projects laterally between the side` guides and into the lifting frames N to engage their cross bars NX- as shown. Itshould be stated however that just before the barH en-4 same time set the two tripper mechanisms,"

which occurs just after the stem KX and the rod X have been elevated to engage the trippers L LX.

From the foregoing it will be seenthat after the magnet Q is energized to trip the arm LX, and the hydraulic means set in operation, the devices which set in operation such hydraulic means are automatically reset by the saidvhydraulic elevating means, as are also the valve opening mechanism and its electric tripping devices I also utilize such elevating or hydraulic means to automatically operate to cut off the water supply from the cylinder G, and for such purpose I employ the devices shown to the right in Figs. 2 and 25 and also in Figs. 8 and 9, which consist of a cage or frame G5 normally suspended bya cross bar g5, from a hook or supporting finger g5, and guided at its upper end in a loop g7.

Atthe lower end of the frame-G5 is secured a weighted socket member G5, in which is held for free movement a push rod g8 as shown, which normally rests upon the cross bar u. To the cross barg5 is secured one end of a chain or cable H5, which passes up over a pulley h5, held between the guides g g, and passes down through an aperture h5 in the the cross bar H and carries at its lower end a collar or weight k7. Such bar H has a projecting guide J5, the outer edges of which pass between the rods g r 0f the frames G5, and such guide .I5 has a roller 7'5` which engages the cross rod g5 when the piston .I is at its highest point and moves such rod g5 from the hook finger g5.

Referring now to more particularly to Fig. 25 it will be noticed that when the levers U have been depressed by the rod X, the member u' is as the position shown in dotted lines, which forces the push rod g8 up in'to the pocket of the member G5. Now as the cross bar H is moved up as before stated, and just as soon as it reaches its uppermost position, its guide J5 will force the frame G5 from the hook g6 and thereby allow the weighted member to drop against the cross arm u', and as the opposite weighted socket has been also elevated it follows that the valves U will be rocked' frame G5 and raise it until its bar g5 slips over the hook g5, the rollerj5 serving as a convenient guide for the outer end of the chain or cable during such operation.

From the foregoing taken in connection with the accompanying drawings, it is thought the complete operation of my improved mechanism will be readily understood.

By the construction shown, the entire operation of turning off or turning on the valve in the stand pipe lateral as Well as an antomatic resetting of all of the mechanism can be accomplished by a mere turning of the crank of an electro magnet to energize the electric operating devices. The several parts are so constructed and arranged as to positively operate and automatically connect themselves during the operation of closing the valve in the stand pipe lateral. It is manifest that in the practical construction of my invention the detail arrangement and construction of parts may be modified Without departing from the broad ideas of my invention. I do not therefore limit myself to such construction.
