Specification of Letters Patent.

Patented Nov. 12, 191,8.

r Application led December G, 1917. Sera1No.205,855.

To all whomc't may concern:

Be it known that I, DAVID S. RYAN, of the city of Toronto, in the county of York, in the Province of Ontario, in the Dominion of Canada, prospector, have invented certain new and useful Improvements in Valves, and do hereby declare that the following is a full, clear, and exact description of same.

This invention has for its object to provide for the controlling of fluid under an intermittent pressure to be admitted to a plurality of' receivers or devices in which it is desirable that a maximum predetermined pressure shall be attained in a consecutive order in such receivers or devices, the operation of such means to be automatic inefegting such selective pressure distribution without requiring mechanical assistance or involving the use of mechanical timing arrangements.

A further object is to provide a combined valve having a plurality of passages therein for Huid circulation, the said passages being isolated one from another by pressure-operable means, whereby the operation of said last-mentioned means due to pressure in one of' the said passages, may effect the closing of the adjacent passage to prevent fluid circulation therethrough.

Further objects subsidiary to or resulting from the aforesaid main objects, or from the construction of the invention as it may be carried into effect, will become apparent as the nature of the said invention is hereinafter further disclosed.

In carrying the said invention into effect, I may provide within a suitable casing two expansible chambers, such as short lengths of substantially flexible tubing, each connected at opposite ends to inlet and outlet pipes or conduits extending from the said casing, the said expansible chambers being arranged one above the other and in contact, and occupying a restricted space within the casing in such manner that the expansion of one of the said chambers will result in the pressing together of the walls of the said chambers, closing, or more or less closing, the same, according to the difference in the pressure in each of the said chambers. In such a construction, the outlet pipe from one of the said chambers may bek connected with a receiver in which it is desired a certain pressure shall be primarily attained, and the said receiver also connected with the inlet pipe of the other of the said chambers, the outlet pipe of which is connected with a second receiver, whereby-the restriction or closing of the second expansble chamber, due to the inflation of the first chamber while fiuid under pressure is being admitted to the first-mentioned receiver, will prevent the charging of the second receiver until such time as the pressure in the first receiver shall have risen to a sufficient and predetermined extent to cause the expansion ofl the second chamber against the e'ort of the rst chamber, all of which is more particularly described and ascertained in and by the following statement having reference to the examples shown in the accompanying drawing, in which Figure l is a diagrammatical view of a valve embodying this invention coupling a pair of receivers:

Fig. 2 is a vertical section of such a valve taken on the line 2"- Fig. l.

Fig. 3 is a similar view to Fig. 2 showing the valve in a different stage of its operation.

Similar characters ofy reference indicate similar parts in the several figures of the drawing.

In Fig. l, a and indicate the receivers or kany devices in which intermittent and consecutive pressure is desired, in this example it being presumed that a certain presT sure is to be attained in the receiver a prior to the admission of fluid under pressure to the receiver b, and l indicates a valve casing provided with primary inlet and outlet pipes 2 and 3 and with secondary inlet and outlet pipes 4 and 5 respectively, the pipe 3 being connected with the receiver a and the pipe 2 with the source of fluid under pressure, while the secondary inlet 4 is l also connected with the receiver a and the outlet 5 with the receiver b. 6 is an expansible chamber connecting the parts 2 and 3, and said chamber in the example shown in Figs. 1, 2 and 3 comprising a flexible tube, preferably of a substantially fiat cross section, as indicated in Fig. 2, and 7 is a similar expansible chamber connecting parts 4 and 5, and being arranged within a restricted space 8 with the said chamber 6, the two chambers being thereby in lateral contact. It will be seen that upon admitting fiuid Linder pressure to the receiver a through the expansible chamber 6, said chamber will be inflated within the restricted space 8 in the casing, and will consequently press the walls of the chamber 7 to gether, as indicated in Fig. 2, so that fluid will be enabled to pass through the said chamber 7 from the receiver a, until such time as the pressure therein has increased t0 a predetermined extent to overcome the resistance of the chamber 6 to the opening of the said chamber 7, whereupon the said chamber 7 will be inflated against the pressure of the chamber 6, as is indicated in Fig. 8, and the fluid admitted to the receiver b is required.

It will be readily understood that the designing of the valve can be easily arranged to determine the pressure at which the chamber 7 will operate, such as the proportioning of the respective areas of the said chambers or the inlets to the same, and so on; and it will also be understood that where the fluid pressure admitted to the chamber 8 is intermittent upon the relief oi' such pressure after the charging of the said receivers, said receivers will discharge through the said valve in consecutive order due to the operation of the said chambers in the manner already described.

This invention may be developed within the scope of the following claims without departing from the essential features of the said invention, and it is desired that the specification and drawing be read as being merely illustrative and not in a limiting sense except as necessitated by the prior art.

llVhat I claim as my invention is l. In a device of the class described, a primary conduit, having inlet and outlet portions, a secondary conduit also having inlet and outlet portions, the inlet portion Copies of this patent may be obtained for of said secondary conduit being adapted to receive iiuid under pressure from the outlet conduit of said primary conduit, an eX- pansible chamber in said primary conduit, and a further expansible chamber in said secondary conduit, said chambers being cooperative, whereby pressure in the chamber of said primary conduit will eifect the closing of the chamber in said secondary conduit to fluid passage therethrough, and whereby said chamber in said secondary conduit will be expanded against the effort of said first mentioned chamber upon the pressure within the outlet portion of said primary conduit having attained a degree overcoming the effort of said primaryconduit chamber.

2. In combination with a pair of receivers, a primary conduit leading to one of said receivers, a secondary conduit leading from such receiver to the second of said receivers, an expansible chamber in said primary conduit, and a further expansible chamber in said secondary conduit, said chambers being cooperative, whereby pressure in the chamber of said primary conduit will effect the closing of the chamber in said secondary conduit to the passage of iiuid therethrough, and whereby said chamber in the secondary conduit will be expanded against the effort of said first-mentioned chamber upon the pressure within said first-mentioned receiver having attained a degree overcoming the effort of said primary conduit chamber.

Signed at the city of Toronto, in the county of York, in the Province of Ontario, in the Dominion of Canada, this 30th day of November 1917.

DAVID s. RYAN.
