C. LAIDLEY, residing at pact in size and of a strong and durable construction.

vFurther objects of the invention are, to provide `means for varying the amount of movement of the main controlling valve, so as to permit a relatively long or short duration of flushing; to provide means for ad' justing the flow of liquid through the outlet passage so as to permit of the 'flow being entirelycutoif if necessary; and to provide means for adjusting the flow of water through the inlet passage so as to permit-of the cutting oli 'of the How of water through said passage in order to repair or adjust the operating portions of the valve.l

The invention further consists in the features of construction and the combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal sectional view of the valve of the present invention; Fig. 2 is a view similar to Fig. 1, showing the parts adjusted to permit of an increased movement of the main controlling valve; Fig. 3 is a section on line 3-3 of Fig. 2; Fig. 4 is a detail showing the controlling member for the outletport when it is in position to close said port; Fig. 5 is a detail showing the mechanism for closing the inlet port; and Fig. 6 is a view similar to Fig. 2, showing the main controlling valve in unseated position.

The device as shown in the drawings is inclosed within a casing 7, consisting of an upper enlarged portion 8, which terminates in a lower reduced portion 9, the upper end of the casing being closed by a cap or cover 10. Inter-posed between the cap or cover and the upper edge of the casing is a packing member 1l, and extending through said cap or cover are a series of locking members 12, which engage with a member 13 that is mounted to revolve within the casing, andv in the county of Cook and State ofy which has its side walls cutaway at intervals, as shown more clearly in Fig.` 3, to provide cut-ott members 14 for the water outlet passage. Secured to the lower end of the member 13 is a cup washer kor other suitable packing 15, held in place by a ring 16 which is locked in position by suitable locking members 17. The member 13, as shown, is screw-threaded into the interior of the enlarged portion 8 of the casing, and is capable of being raised and lowered therein. The purpose of this raising and lowering will be more fully hereinafter stated.

In addition to the up and down adjustment, the cup-shaped member may be turned within the casing so 'as to bring the cut-oil' members. 14 to the desiredv position with respect to the outlet passage. When they are in the position shown in Fig. 3, the outlet passage 18 is entirely unimpeded and a free flow of water from the casing through the outlet passage is permitted. If, however, the members are turned so as to lie in` a position at right angles to the position in which they are shown in Fig. 3, one of the cut-ott1 members 14 will be positioned across the outlet passage 18, and, in this position it will cut off the iow of liquid from the casing through the outlet passage. This complete kcutting o of the flow of water through the outlet is to permit of the removal of the iXture for the purpose of repair, substitution, etc., without the danger of leakage of water ensuing by reason of the disconnecting of the fixture from the outlet conduit of the iiushing valve. By manipulating the member 13 so that theIcut-o members 14 assume positions intermediate the two extreme positions formerly described, said cut-oli' members may assume a position so that the outlet passage will be more or less restricted and the flow of water out from the casing into the fixture more or less voluminous.

The cup washer 15 and the ring 16 serve asa seat fora hollow valve member i9, which in the form shown is of cup-shaped format-ion, this valve member 19 being the main controlling valve between the outlet passage 18 and the inlet passage 20. The valve melnber. 19 is formed, on its upper portion, with a seating face 21, ancLis provided with unbroken side surfaces 22, which en age, with a sliding fit, the side faces of a ead 23, from which depends a,v sloping wall 24- secured to the body of the casing ramasse are so arranged as to give the valve member a relatively short movement, while in Fig. 2 the parts are arranged to give it a relatively long movement. lt is, of course,F understood that the head 23 is Xed at all times and does not vary its position with the adjustment of the main controlling valve 19. It is the presence of this fixed head, located in theinterior of the hollow valve member, which enables the suctional force to ybe created thaty acts as a retarder to prevent the quick return of the valve member to normal position.

It will be noted that the stem 33, which forms a restriction for the entrance of the fluid into the interior of the main controlling valve, operates in a manner so that it is continually cleansed during operation, thus prevent-ing the gathering of sediment, which would tend to check its movements and interfere with the proper operation ot the valve. This point of cleansing the operating parts of the valve applies equally well to the-parts other than the stem, and, in fact, the valve is so arranged that there is a passage of water at each operation, which tends to remove any dirt or sediment which may enter, and thus keep the operative parts in the most desirable condition for satisfactory operation.

claim:

l. lln a flushing valve, the combination of a main casing, an inlet passage and an outlet passage communicating therewith, valvular means tor controlling the communication between the inlet and outlet passages,`

Aincluding a sliding valve, means for actuating said valve, a circular box-like member adjustably mounted in the interior oi the casing and interposed between the inlet and outlet passages, said box-like member having an opening in its bottom wall kept normally closed by said valve, said opening forming the communicating passage between the -inlet and outlet ports, the location of the`boX-like member determining the deee of movement of the valve, the side walls of the box being cut away to provide a plate-like member adapted to overlie and govern the size of the outlet passage, said governing member being moved to dilierent posit-ions by an adjusting movement of the box-like member, substantially as described.

2. ln a flushing valve, the combination oi a main casing, an inlet passage and an outlet passage communicating therewith, val- 4mally closed by said valve, said opening forming the communicating passage between the inlet and outlet ports, the location of the box-like member determining the degree of movement of the valve, the side walls of the box being cut away to provide a plate-like member adapted` to overlie and govern the size of the outlet passage, said governing member being moved to dierent positions by an adjusting movement of the box-like member, and means for locking the said box-like member against movement within the casing, substantially as described.

3. ln a flushing valve, the combination of a mainlcasing, an inlet passage and an outlet passage communicating therewith, valvular means for controlling the communication between the inlet and outlet passages, including a sliding valve, means for actuating said valve, a circular box-like member adjustably mounted in the interior of the casing and interposed between the inlet and outlet passages, said box-like member having an opening in itsbottom wall kept normallyv closed by said valve, said opening forming the communicating passage between the inlet and outlet ports, 'the' location of the box-like member determining the degree of movement of the valve, the side walls of the box being cut away to provide a plate-like member adapted to overlie and govern the size of the outlet passage, said governing member being moved 'to dierent positions by an adjusting movement ot the box-like member, a cap for the casing, and locking members depending -from the cap and engaging with the box-like member to prevent movement thereof, substantially as described.
