Specification of Letters Patent.

Patented Nov. 28, 1916.

Application led April 14, 1915. Serial No. 21,375.

To all 'whom t may concern Be it known that I, BENJAMIN KAPLAN, a citizen of the United States, and a resident of New York, borough of Bronx, county oi Bronx, and State of New York, have invented a certain new and useful Improvement in Valves, of which the following is a full, clear, and exact specification.

This invention relates more particularly to a class of devices adapted to be used in conjunction with water pipes and the like.

My invention has for its object primarily to provide a four-way valve designed to be employed in a manner whereby the passage of water and other liquids through pipes may be controlled, and which is of a form adapted to control the flow and the cuttingoif of the liquid from one orboth of two independent sources of supply so that the liquid may be caused to flow from either one or both of the sources alternately or at the same time to either one of two outlets, thus avoiding the requirement for using a number of separate valves to allow water to' be discharged from two independent supply pipes to two distinct outlets. This is accomplished mainly by providing a casing formed with two inletsV in opposite parts thereof for admitting a liquid' from either or both of two independent sources of supply, the casing having an outlet midway between its inlets, and having in the part of its wall opposite to the first outlet a. second outlet unequally distant `between the inlets. In the casing is a rotatable controller or valve member having part of its peripheral surface transversely cut-out or slotted to provide a passage between the valve and the wall of the casing adapted to be registered with the inlets and outlets sothatvwhen the valve is revolved properlythe liquid will flow from one, orboth of the inletsthrough the passage to either one of the outlets, or to permit all of the inlets and outlets to be closed in unison against the flow of liquid through the valve.

A further object of the invention is to provide a valve of simple and efficient construction, and which is susceptible of being made to combine strength and durability.

Withy these and other objects in view, the invention will be hereinafter more particularly describedwith reference to the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, and will then be pointed out in the claims at the end of the description.

In the drawing, Figure 1 is an elevation of a bath tub fixture showing the manner of using a valve embodying my invention in conjunction therewith. Fig. 2 is a top plan of the valve. Fig. 3 is a sectional view, partly fragmentary and partly in detail, takenfon the line III- III of Fig. 2. Fig.

l is a longitudinal vertical section taken ing the position of its valve when the flow of liquid through the device is entirely cutoli'. l

The device, or valve has a casing, or body, as 10, formed with a circula-r bore 11 which is preferably tapered, and part of this bore forms the passage through an exteriorly threaded boss l2 extending from a part of the outer surface of the casing. The bore 11 terminates at an'o-pposite part of the' casing, and communicating with this end of the bore is a hole 13 passing through the wall of the casing and through an exteriorly threaded boss 14E projecting from the ycasing opposite to the boss 12. Transversely through the casing, and' cormnunicating with the bore 11, are two registeredinlets, or passages 15 and 16. Preferablypart of the inlet 15 is interiorly threaded to permitV f the device to be screwed on a pipe leading from a source of water,vor other liquid supply, andv part of the inlet 16 is also interiorly threaded to adapt the device to be screwed on a pipe leading from a second` source of water, or other liquid supply. Also extending transversely through the casing from the bore 11 and substantially at a right angle with respect to the inlets 15 and 16 and midway therebetween is .an outlet, or passage 17 leading through a preferably interiorly threaded boss 18 to permit a pipe for distributing the liquid to be screwed thereinto. In part of the casing opposite to the outlet 17, and unequa'lly4 lets.

distant between the inlets 15 and 16 is a second outlet, or passa-ge 19 one end of which communicates with the bore 11, and this second outlet is preferably on an incline, as shown, so as to lead through a nipple 20l provided on the casing diametrically oppo.

site to the outlet 17. The object of providing this second outlet 19 at a point unequally distant from the two inlet ports, permits the flow and discharge of water to be completely stopped when the valve is in the position 'as shown in Fig. 7, and it will be clearly seen that such stoppage of the flow of the fluid would be impossible were the second outlet set opposite the first as is customary. 1t will thus be seen that I have provided a valve where there is a clear and uninterrupted passage between the two inlets and either one of the outlets, or between either one of the inlets and either one of the outlets, and yet because of the peculiar arrangement of the second outlet, the flow of water can` be completely stopped.

In. the casing is a rotatable valve 22 serving to control the How of the liquid thro-ugh the casing from either one or bot-h of the inlets. alternately to one or| both of the out- The valve 22 is disposed in the bore 11A of the casing, and is of a frusto-conical shape so as to conform with the shape of the bore. The valve 22 is of a size to t snugly in the bore, but to allow it to be freely ro-.

tated therein, and projecting from one end of the valve is a post 23 revolubly disposed through the hole 13 of the casing. rlhe post 23y is of a length to extend so-me distance outwardly of the casing, the outer end of the post being eXteriorly threaded, and this end of the post is rotatablyseated in a recess interiorly of a threaded cap, as 24, which is screwed on the threaded boss 14, a nut 25 being screwed on the threaded end of the post and a gasket 25l being arranged lbetween the nut and the boss 14 to prevent leakage of liquid through these parts. EX- tending from the opposite end of the valve 22 is a; Second post 24 disposed through a nut 26 having an interiorly threaded endV screwed on the threaded boss 12 of the casf ing, and this nut has an oppositely disposedv interiorly threaded annular extension, as 2.7, which surrounds this post. The eXtension 27 of the nut 26 is of a diameter so as to be spaced from the post 24, and in the concentric recess thus formed is a gasket 28 held against accidental displacement by a stuiflng box 29 encircling the post andV screwed into' the end of the interio-rly threaded extension 27. By arranging these parts 'of the device in this manner they will be prevented fromy leaking, and moreover the valve may be more easily removed from the casing for regrinding, when required, than the ordinary types of valves. In order te permit the valve 22 to be manually rotated, on the post 24 is a handle, as 29, which may be of a length and shape whereby the valve may be conveniently operated. Part of the peripheral surface of the valve 22 is transversely cut-out, or slotted, as at 30, a cross section of the cut away portion being vsecant shaped to provide a passage between the valve and the inner wall of the casing, and this cut-out is adapted to be registered with one, or both, of the inlets together with one of the outlets when the valve is rotated, the handle being arranged relative to the cut-out 30 to allow adjustments of the valve so that liquid admitted into the casing through one, or both of the inlets may flow to either of the outlets, or the valve may be adjusted so as to close in unison all of the inlets and outlets against the passage of liquid.

When the device is in use, for instance in conjunction with a bathtub fixture, as shown in Fig. 1, in the threaded inlet 15 of the casing 10 is screwed an end of a pipe, as 31, leading from a source of liquid supply, such as hot water, and in the threaded inlet 16 of the casing is screwed an end of a pipe 33 leading from an'independent source of liquid supply, such as cold water. 1n the threaded outlet 17 is screwed the pipe, as 34, of a. shower bath fixture for distribution of the liquid or water admitted into the casing second outlet 19 permits the liquid, or water to be discharged from the casing into a bath tub, or other receptacle. To permit a supply of hot and cold water to be admitted into the casing for discharge through the outlet 17 the handle of the valve 22 is rotated so that the valve will be in the position shown,

the valve is adjusted to the position shown.

in dotted lines, at 38 Fig. 5. To permit a supply of cold water to flow from the inlet 16 through the outlet 17 the valve is revolved to a position indicated, at 39 Fig. 6, and to allow hot water to flow from the inlet 15 to the outlet 17 the valve is rotated to a position, shown at 40 Fig. 6. When it is desired to cut-ofi the water in entirety for delivery through the casing 10 the valve is revolved as indicated, at 41 Fig. 7. Thus by employing this form of valve the delivery of liquid from two independent sources of supply for being alternately discharged through one of two separate outlets may be absolutely controlled, and the re- .from one, or both of the inlets, and the Y quirement for using a number of separate valves may be avoided.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications ma. be made therein without departing from tie principle, or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A device of the character described comprising a casing having a transverse bore and four ports opening into said bore, two of said ports being substantially opposite each other, a third port being located at a point approximately midway of the two first mentioned ports, and the fourth port being located in the wall of the casing opposite the third mentioned port and at a point unequally dista-nt from the two opposite ports; and a valve mounted in the bore of said casing having a cut away portion and being capable upon rotation of providing a free passage between the first three mentioned ports, or between either opposed port and the fourth mentioned port, and also adapted to close all four ports.

2. A device of the character described comprising a casing having a transverse bore f and four ports opening into said bore, two

of said ports being substantially opposite each other, a third port being located at a point approximately midway of the two rst mentioned ports, and the fourth port being located in the wall of the casing opposite the third mentioned port and at a point unequally distant from the two opposite ports; and a valve mounted in the bore of said casing having a cut away portion and being capable upon rotation of providing a free passage between both of the opposed ports and either of the other two ports simultaneously, or either one of the opposed ports with either one of the other two ports, and also being adapted to positively close all four ports.

3. A device of the character described, comprising a casing having two registered inlets in opposite parts thereof, and having two outlets one midway between the inlets and the other in a part of the casing opposite to the first outlet, this second inlet being unequally distant from the inlets, and a manually rotatable circular valve in the casing normally closing all of the inletsand outlets, part of the valve being transversely cut-out to provide a passage between the valve and the wall of the casing So that when the valve is rotated accordingly its cut-out will provide communication between one or both of the inlets and one of the outlets to permit a liquid to ow through the casing.

This specification signed and witnessed this thirteenth day of April A. D. 1915.
