Application filed April 28, 1912. Serial No. 893,503.

the invention is to simplify construction and increase the utility of such flush valves by providing a valve of this character which is composed of a few simple parts easily assenibled. and not liable to displacement or breakage under ordinary use.

\Vith this object in view the invention consists in the improved construction, ar-

rangement and combination of parts of a valve of the character specified, which will be hereinafter first fully described and afterward specifically claimed.

In order that the construction and operation of my invention may be readily comprehended I will now proceed to specifically describe it, having reference to the accoin; panying drawing-which illustrates an approved embodiment of the invention. in which drawing preferably a substantially which communication is Figure 1 represents a vertical sectional view of a valve of the character specified connected up to a water supply pipe and a discharge pipe, said pipes being shown in elevation and broken away; Fig. 2 represents a view in elevation of the same parts looking at the left hand side as shown in Fig. 1, parts being broken away and parts shown in section; Fig. 3 represents a view of the upper part of a slightly modified construction partly in elevation, with parts broken away and parts in section onthe same' plane as in Fig. 1.

Like reference characters mark the same parts wherever they occur in any of the figures of the drawing.

'Referring specifically to the drawing 5 indicates the casing of my i'mpr'ovedvalve,

cylindrical casting whichis provided with an internally threaded nozzle 6 on one side to receive a water supply pipe 7, a similar nozzle 8 at thebottom to receive a discharge pipe 9 from had with the closet- Ron, ed upper end l l l bowl, (not shown) and an interiorly threadl to receive a removable cap 11 provided on its interior with a central de pending cylindrical guide 12 to receive the stem. 13 of a valve let the specific construction of which will be later described.

lVithin the casing is a hollow elbow 15 comprising a horizontal arm 18 communicating tglirectly with the supply pipe, and a vertical arm 17 which has its upper and open and terms a valve seat.

The valve stem 13 is plain where it enters the guide 12 and is enlarged and threaded at 18' to fOl'Ill'tl stop 18 upon which threaded portion is threaded a disk 19 in a cup shaped packing 20 which slidably tits in a 5., said packing cup resting on a metallic disk threaded on the stem and forming the valve proper l4: beneath which, on the stem, is a packing dist E22 which normally rests upon the top of the valve seat l7 and is held up on the-stem. against the valve 14, by an inverted cupshaped supplementary valve 23 which enters within said valve seat 17.

A port 24 leads from the horizontal arm 16 of the elbow 15, through the wall of the casing 5, to the chamber 21 and from said chamber projects a horizontal threaded nozzle 25 which receives a sleeve 26 into which is threaded at its outer end a second sleeve 27. which bores are aliiicd with each other, forming a guide for a stem 28 of a valve 29, said stein being reduced in diameter at 30 in an enlarged inner end of the bore. which forms a chamber 31. The valve head, when the valve is closed, which itis normally by a spring 32,.seats itself at the inner end of the sleeve 26 and cuts off communication between the chambers 31 and 21.

The valve 29 may be opened by manual pressure upon a knob 3301i the outer end of the stem 28 against the closing force of the spring 82' which is coiled about the stem chamber 21 lIL'Q-Pd upper-ei-idet'tl e casing between ashoulder in the sleeve 27 and the inner end or the knob.-

A port 34 in the well of the casing 5 leads from the chamber 31 to the lower portion of the casing 5 which is in communication with the discharge pipe 9.

I The upper end of the port 24 may be wholly or partially closed by needle valve 35 (Fig. 2), whereby its discharging capacity maybe regulated.

Each of the sleeves has bore- In the modification shown in Fig, the casing 5, threaded end 10, and cap 11 are the same as in the constructions shown in Figs. 1 and 2 and. previously described. but instead of the horizontal nozzle 25 there is a vertical nozzle :25 to receive the sleeve 26,

portcommunicating between the chamher 3t and the valve casing and a port 34; leading from said chamber. to the lower end of the casing, the whole object of the modification being to bring knob into a position sometimes to be preferred and to have it and the release valve stem move. vertically instead of horizontally.

The operation of the invention may be described as follows: Assuming the parts to be in position illustrated in Fig. l and the chamber 21 filled with water from the supply pipe 7 through the port :24, the pressure ofthe water in said chamber will tend to keep the valves lat and closed, the latter also having the pressure of the spring 32, thus cuttlng oti all connection between the supply pipe 7 and the discharge pipe 9.

By pressing inwardly on the knob the valve "29 is opened, permitting the water to flow from the chamber 21, around valve 29, through chamber 31. and port 3t to the ca ing and the discharge pipe, \vl 'ch will release the pressure in chamber 21, so that the pressure of the water from the supply pipe 7 through the elbow- 15 will raise valve 1-lt off its seat and open a passage for the supply of water out of the elbow, below the raised valve 14 and out at the lower end of the casing and discl'iarge pipe 7, thus flushing the bowl. The spring 32 will have closed the valve 25), and, the water continuing to flow through port 24, the chamber 21 will be again filled, and the valve 14 closed by said pressure, when the flushing will cease, the length of time during which the flushing will be continued depending upon the regulation of the discharge through port 24 by means of the needle valve From the foregoing it will be seen that .l have provided a strong, simple, and economical flush valve the character described, and while I have specifically described the construction, location, and operation of the various parts composing the same, I desire it to be understood that slight changes and variations may be made thereoeonss in, without departing from the spirit and scope of the invention as defined in the appended claim. I

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is-- v A flush valve of the class described, comprising a casing, having an inlet and an outlet, said inlet being in the form of an elbow disposed within the casing and consisting of a horizontal and vertical arm, the horizontal arm being extended to provide a threaded coupling adapted to connect with a supply pipe; a threaded cap on said casing, said cap having a guide sleeve depending therefrom, a valve stem slidable within the guide sleeve, said valve stem having an enlarged threaded portion producing a shoulder adapted to contact with the guide sleeve and constitute a stop, a piston valve disposed upon the threaded portion of the valve stem and consisting of a dish, a cup shaped packing superposed on said disk, the side of the packing being flush with the edge ot the disk and contacting with the interior of the casing, a second disk threaded upon the valve stem, said second disk being less in diameter than the first disk and arranged within the cup shaped packing, the edge of said second disk contacting with the inner side of said packin an inverted supplemental cup-shaped valve threaded upon the valve stem and normally disposed within the vertical arm, and packing disposed between the supplemental valve and the first n'ientioned disk, said piston valve eot'rperatiug with the casing to form in the upper end thereof a main water chamber, a by-pass through said casing from the horizontal arm of said elbow to the main water chamber, a screw threaded needle valve adapted to control the flow of water through said lay-pass, a passageway connecting the main water chamber with the outlet, and a manually-operated spring pressed valve con trolling said passageway.

In testimony whereof I my signature in presence of two witnesses.
