`.`l`?I|liRCY W." H'OIDGKINS'ON, OF ROCHESTER,` NEW YORK, ASSIGOR OF ONE-FOURTH T0 WILLIAM H. CALDWELL, OF' ROCHESTER, NEW YORK.
lBe it known that I, Pelzer W. HovoxrN- soN, acitizen of the United States, and resident of Rochter, in the county of Monroe and State of New York, have invented certain new and useful Improvements in 'Valves, of which the following is a specification.
My invention relates to valves o'f the type in which the vnecessit for a stuffing-box is avoided by the use o a flexible diaphragm, which permitsa valve within the diaphra to be moved by means external to the dlaphragm.
One ob'ect of my invention is to provide a valve o the kind above referred to with a guard by means of which the valve is protected' against accidental application of 'pressure to the diaphragm,l such as would operate to open the valve unintentionally.
A second object of my invention is to produce a valve of the kind above referred to which is adapted for discharging a measured quantity of fluid.
In the accompanying drawings: Figure 1 is a vertical median section showing a complete valve embodying my invention; Fig. 2 is an elevation of the valve of Filg. 1, looking from right to left in Fig. 1; 4ig. 3 is a view similar to Fig.1, of a modified form of the valve arranged to operate as a mea-surin yvalve; and Fig. 4 is an elevation of the va ve of Fig. 3, looking from right'to left in Fig. 3.
In the embodiment of my invention illustrated in Figs. 1 and 2, the valve is provided with a body 1 which is chambered to form a fluid passage. .Two openings into the fluid passage, 2 and 3 respectively, may be used alternatively'as an inlet and an outlet. The opening 3 is located in a plug provided w1th a valve seat 4 which coperates with a conical-ended member 5 const-ituting the valve pro er. The valve 5 slides longitudinally in t e 'valve body, and is guided by a circumferential flange 6. The end of the valve 5 passes outward through a third opening 7 from the fluid passage, and engages a recessed boss 9 fixed in the center of a diaphragm 8. The diaphragm is composed of thin, flexible, corrugated metal, and is attached to the body 1 by a suitable 'fluid-tight connection, so Ithat the diaphragm acts as a closure for the open- VALVE.

T0 all fitmay concern:
ing 7. A compression sprin about thevalve 5 engages the gauge 6, and tends constantly to move the valve to the right, awa from lthe valve seat 4, so as to o en the uid passage. This movement of t e valve is permitted b the diaphragm owing the valve to its left-hand or open osition. against the com lished to t e outside of the diaphra the diaphragm being accessible for t is urpose. A button 21 is fixed at the center of t e outer surface of the diaphragm. A uard 22 partly incloses the outer surface o the diaphragm, but it is plrov'ided with a central aperture through w ich the button 21 is accessible. This valve is opened by pressing with the thumb against the'button-21, but the form and arrangement of the guard is such that the accidental application of pressure to the diaphragm is practically impossible, so that t e contents of the receptacle will not be accidentally released in case the valve be struck or the recept-acle fall upon its side. The head of the valve is slotted, asshown in Fig. 5, to ermit the linsertion of a screw-driver by which the valve may be turned to rub or grind it to an even bearing on its seat or free it if clogged by viscous or dried material. y
In the modified form of the valve illustrated in Figs. 7 and 8, the valve-proper 5 is arranged to be self-opening but in addition to the valve 5 there is a second valve 24 arranged to be self-closing as in the con-- structions illustrated in Figs. 3 and 5. Both valves are controlled by the same diaphragm 8, which is provided with a button 2l to be pressed by the thumb and with a centrallyerforated guard 22 inclosig a portion o the outer surface of the diaphragm. If the valve body be connected with a fluid rece tacle, so that -the opening 2 .constitutes the inlet into the valve body, a measured quantity of vfluid may be delivered through the valve by pressing the button 21, thereby opening the valve 24 and closing the Valve 5 and permitting the fluid in the valve body and the diaphragm chamber to flow out through the valve 24. When the button is released again, the valve-26 closes and the valve 5 opens, thereby permitting Huid to flow from the source of supply Patenteaaan. 3, 1911.
1o oiled to its elasticity. he movement o 'Y through the inlet 2. Since the chamber formed between the ,diaphragm 8 and the plate 2O constitutes a ortion of the measuring recess, the gui e anges 6 on the valves are notched, as shown in Fig. 8, to permit the free passage'of iuid .into and out of this chamber.
My invention is not limited tothe embodilnent hereinbefore described and illustrated in the accompanying drawings, but vmay be embodiedin various forms within the nature ofthe invention as'it is defined in the followclaims: claim z-f 1. The combination of ya valve body pro-` vided with a fluid passage. and with three openings including an inlet and an outlet, a valve .1n the fluid passage, a spring in the fluid assag'e engaging the valve andarranged` to move it -into position to close the tluid passage, a diaphragm connected with the valve and closingthe 'third of said openings, a guard substantially inclosing the outer surface of'the diaphragm 4but provided with a substantially central opening, and means projecting from the diaphragm into, but not substantiall beyond, said opening to permit the app ication of pressure to the diaphragm to move the diaphragm and the valve inv opposition to .the spring. f v
2. The combination of a valve body rovided with a fluid passage and with t ree openin includin .two va ves locate in the iuid passage and an inlet and an outlet, i
in one direction, and a diaphragm connected withthe valves and closing the third of said openings.
3. The combination of a valve body pro'- vided vwith a fluid passage and an inlet and an outlet; a valve in the Huid passage arranged to close the outlet against the direction of flow of the iiuid and accessible through the outlet, the valve having its head slotted to receive an instrument inserted through the outlet to rotate it; and means for normally retaining the valve upon its seat.
