To all whom, it may concern;

Be it known that we, PETER JAMES CAT- 'TERALL and EDWARD Brncn, both subjects of theQueen of Great Britain, residing at Man- 5 chester, in the'county of Lancaster, England, have invented a new and useful Improvement in Valves for Regulating the Supply of Water or other Liquids, (for which we have obtained a Patent in Great Britain, No; 5,611, bearing date November 25, 1882, and in Belgium, No. 61,537, bearing date May 30, 1883,) of which the following is a specification.

Our improvement relates to the invention for which we obtained Letters Patent of the United States No.' 253,683, dated February 14,

1882, and is partly or wholly applicable for other purposes and the objector our invention is to form an improved valve for regulating the supply of water or other liquid. WVe attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is an elevation showingthe valve applied to apparatus for raising beer or other liquid. Fig. 2 is a sectional elevation upon a larger scale of the valve. Figs. 3 and 4 are sectional elevations of a modified form of the valve. Fig. 5 is a sectional elevation of the back-pressure valves. Fig. 6 is an elevation, partly in section, of the ball-valve in the water-supply pipe, and of the treadle for actuating the same. Fig. 7 is a plan of Fig. 6. Fig. 8 is a sectional elevation of an air-vessel for the prevention of concussion in the water-supply pipe; and'Fig. 9 is a detached view in section, showing our arrangement for connecting the chamber to the water-chest.

Similar letters refer to similar parts'throughout the several views. 7

In Fig. 1, a is the stillage, and b is the barrel containing the beer or other liquid to be raised. To the tap of this barrel isconnected one end of the flexible tube a, the other end 1 of which is connected to a backpressure valve, (1, (shown on an enlarged scale in Fig. 5,) communicating by the pipe with the upper. part of the chamber e. This chamber is made in halves, and a diaphragm, Z, Fig. 9, of india-rubber or other pliant or flexible material, is fitted in the chamber, the periphery of the 50 diaphragm being even With the periphery of the flanges of the halves ofthe chamber, which are then bolted together. This diaphragm effectually prevents any liquid admitted to the upper part of the chamber 0 from mingling with the water or other liquid 5 5 admitted to the lower part of the chamber 6. The upper part of the chamber 6 communicates through the back -pressure valve f (shown on an enlarged scale in Fig. 5) and pipe 9 with the deliverytap h. The lower part of the chamber 6 is connected to the water-chest j by the taper-socket t in the manner shown in Fig. 9, and'may be easily removed, if desired. Water is admitted to the water-chest j through the valve (shown on an enlarged scale in Figs. 2, 3, and 4.) and supply-pipe Z, connected to the cistern. To the supply-pipe Zare fitted the air-chamber m (shown in Fig. 8) and ball-valve n, actuated by the spindle n and treadle 0, as shown in Figs. 6 and 7. Awaste-pipe, p, is connected to the lower part of the valve is. The bend in the waste-pipe is level with the top of the chamberaand is for the purpose of keeping the chamber charged with water when the 7 beer in the barrel is run off.

In the valve k, as shown in'Fig. 2, q is the upper and larger diaphragm, and q is the lower diaphragm, both of which are fixed to a tube, q. The periphery of each diaphragm is secured between the flanges of the shell or case 70, as shown at 70 and k. A chamber, (1 is fixed to the lower end of the tube (f. The chamber g contains a ball, g, which rests on and closes a seating, (1 and thus forms a valve. In the lowest part of the shell 70 is fixed the waste-pipe 19, that may enter the chamber g and be closed by the ball g as shown in the drawings. To the top of the shell is connected the water-supply pipe Z, provided with the treadle-valve a. From the side of the low est part of the shell projects a pipe, 2', connected to the-water-chest j, to which water is to be supplied. WVhen it is desired to admit water to the water-chest j, the treadle-valve a of the water-supply pipe Z is opened and water admitted to the valve 7c, the pressure of g Water flows through the tube g around v and the air-vessel m.

the ball g" (which then rests on and closes the waste-pipe p) and through the side pipe, 0', into the water-chest j. lVhen the treadle-valve a of the water-supply pipel is closed, a spring,

s, lifts the diaphragms, tube f, and chamber q. The ball (1 is thus raised from the wastepipe 1) and rests on and closes the seating q at the bottom of the chamber q, and allows the waste water to escape through the waste-pipe 1;. As the springs raises the diaphragms, water passes through the vent-hole q", (formed in the bottom of the chamber q,) and thus allows the diaphragms to be raised. A hole, k", is made in the shell 7., and when it is desired to raise the diaphragms, tube q", and chamber q by water, instead of the spring 8, a pipe, 7.5, is attached, which is connected to the main water-supply, the pressure of which is continuous. This pressure of water raises the diaphragms and tube whenever the treadle-valve n is closed, and the supply of water through the pipe Z is shut off from the upper diaphragm,

In the modified form of the valve 7.1, as shown in Figs. 3 and 4, only one diaphragm is used, the lower diaphragm being dispensed with. The shell is made in two instead of three pieces, and the chamber and tube g are formed in one piece. Fig. 3 shows the diaphragm q and tube q raised, the treadle-valve n being closed and the pressure of water in the supply-pipe if being shut off. The ball q rests in the seating 96' at the bottom of the chamber q and closes the valve. Fig. 4 shows the diaphragm q and tube q in the position they would occupy when the treadle-valve n is opened and the pressure of water through the supply-pipe l is admitted to the valve k. The ball q rests upon and closes the waste-pipe p, and water flows through the tube q and pipe 1 into the water-chest j.

Fig. 5 shows the back-pressure valves (1 and f connected by the pipe 0. Each of these valves (1 and f is formed of a ball resting upon a seating. Pieces of wire (1 and f are fitted to prevent the balls from closing the pipes c and g, respectively.

In Figs. 6 and 7, a is the ball-valve, and 0 is the treadle which actuates the valve-spindle a, secured to a flexible diaphragm, 15*, held at its periphery between the flanges of the body of the valve. The ball it rests in a conical seating near the foot of the water-supply pipe Z.

In Fig. 8, m is the air-vessel placed between the treadle-valve a and the water-supply cistern, to prevent concussion in the pipes. m is the india-rubber air-ball placed within and nearly filling the interior of the shell. Zis the pipe which carries the water-supply from the cistern into and out of the air-vessel m to the treadle-valve a, and thence to the valve h. To regulate the flow of water in the pipe I, a screw-down tap is placed between the cistern (This tap is not shown in the drawings.)

Fig. 9 shows the lower part of the chamber a connected by the taper soeketi to the waterchest j.

The mode of operation of the whole apparatus is as follows: The beer or other liquid flows from the barrel 1) through the tube a, valve 01, and tube a and fills the chamber 0. \Vhen it is wished to draw beer, the tap h is opened, and the treadle o is operated so as to raise the ball. in the valve a and admit water or other liquid through the supply-pipe Z, valve 76, pipe 0', and chest 3' into the lower part of the chamber 0. The pressure of the water forces up the diaphragm in the chamber c, raises the beer through the pipe 5 and delivers it through the tap h. The backpressure valved prevents any beer from being forced back into the barrel 1). \Vhen sufficient beer has been drawn, the treadle 0 is released, and the ball allowed to fall and close the valve or and shut oli the supply of water through the pipe Z. The diaphragms and tube q then rise in the valve k and allow some of the water to escape from the chamber c and chest 7' through the waste-pipe p, and the beer from the barrel 1) again fills the ehamberc. The baclepressure valve f prevents any beer from returning from the pipe 9 to the chamber c.

Having stated the nature of our invention and described the manner of performing the same, we declare that what we claim, and desire to secure by Letters Patent of the United States, is I 1. The combination of a spring-pressed diaphragm having an inlet, allowing the flow of liquid in the direction opposite to the press ure of said spring, with a tube extending through said diaphragm and movable therewith, two outlets arranged below said tube, and a valve which closes one of said outlets when the liquid flows as aforesaid, but leaves it open when the liquid ceases to flow in that direction, substantially as set forth.

2. In combination with the beer-vessel, pipes, backflow-valves, and diaphragm-chamher 0, arranged substantially as described, devices for letting 011 or cutting off the sup ply of water at any time, and a valve provided with a spring pressed diaphragm, a tube extending through said diaphragm and movable therewith, two outlets-one extending to the diaphragm-chamber c, the other allowing escape of water-and a ball which automatically closes the latter when the flow of water is let on to force out the beer, substan-v tially as described.

The foregoing specification of our improvement in valves for regulating the supply of water or other liquid signed by us this 30th day of October, 1883.
