SWITCH-VALVE.

Specification of Letters Patent.

Application filed October 24, 1910.

Patented Apr. 11, 1911. Serial No. 588,616.

To all whom it may concern:

Be it known that We, HENRY MOELLER, ENGELBERT KIEWEG, and FRANK WAGNER, all of Milwaukee, Wisconsin, have invented a Switch-Valve, of which the following is a specification.

This invention relates to manifoldingvalves, that is to say, devices of that type which are adapted to receive liquid from a given source, as for example a pipe or duct, and deliver it into one or more of a plurality of branch-ducts or pipes as desired.

Valves of this class are largely in use for shower-baths, and the present invention is particularly adapted to this purpose; while at the same time it will undoubtedly serve equally well for many other purposes, and we therefore do not confine ourselves to any particular use.

According to our invention we provide a plurality of different nozzles each adapted to be connected with one of the branch-pipes, valve-mechanism adapted to open and close each nozzle at will, and devices for independently actuating the valve-mechanism of each nozzle.

The nature of our invention is more particularly disclosed in the following detailed description and is specified in our claims.

Referring to the accompanying drawings, Figure 1 shows in longitudinal section and Fig. 2 in plan an improved form of valve constructed according to our invention; Fig. 3 illustrates in plan how two or more valves may be connected in series. In Fig. 1, a few of the parts which are in front of the plane of section are shown in elevation.

We provide a body-member A, ordinarily a metal casting, having four branches or nozzles a radiating from the center preferably at right angles with each other and in a horizontal plane; and at the bottom of the member A is an inlet or supply nozzle (1 which may be internally threaded to form a joint with an ordinary pipe or duct B.

Each of the nozzles 11 is bored internally to receive a valve-barrel C, and as shown abutment-shoulders a c are formed respectively on the internal face of the nozzle and on the barrel to fix the position of the barrel in the nozzle and form a tight joint. The barrel is held in place against the shoulder a by a special form of union which makes connection with the branch-pipe or duct D; said union comprising an annular threaded member E adapted to screw on the end of the pipe, a second threaded-member F having a swivcled engagement with the end of the member E by means of the annular lug 6' thereof, and a packingasket G which is compressed between the members C and E when the joint is made up. The nozzle a has an external screw-thread a with which the internal thread of the member F engages and said member Fmay have means for enabling it to be turned, as for example a hexagonal peripheral portion 7. When the joint is made, the valve-barrel C will therefore be held tightly in place and no liquid permitted to leak around it, but the valve-barrel is free to be removed as soon as the joint is made and the valve-plug disengaged from the operating stem as will be hereinafter described.

Each barrel contains a valve-plug H and has a valve-seat 0 upon which the plug H rests when it is closed. Said plug has also guiding-means, such as radial flanges h slid ing on the inner face of the barrel C and also a stem 71 which slides in a central hole bored in a spider c as shown. Means for closing the plug H or assisting it to close are preferably provided; such means as shown comprising a coiled spring I surrounding the stem h resting upon the spider c, and pressing upon the washer it which is held in place by a nut k on the end of the stem 72?. As the fluid-pressure is from within the member A, said pressure will tend to close the valve when open and to hold it closed, and the closing-spring I may therefore not be positively necessary.

For independently opening the four valves H we provide vertically moving stems J which pass through packing-glands K screwed into recesses 01. in the top of the member A and compressing beneath them packing-material L. Said rods J are guided in their vertical movement by the cylindrical bores of the glands K and the bores a in the member A through which the ends of the rods project. Said ends are out obliquely to form cams j which act upon cross-bars it supported by ears it formed upon the valve-plugs H, and each of said bars k is preferably formed cylindrical and provided with a roller h to relieve friction. At the upper end of the oblique cam-faces j is preferably formed a slight depression or notch y' adapted to form a seat or rest for the roller k whereby upon complete depression of the stem J the valve maintains itself in open position when said stem is released.

For depressing the stems J we provide a set of hand-levers M pivoted on the upper end of a central post a which is or may be a part of the body A. Said post carries two pivotpins N, 0, each of which forms the fulcrum of two opposite hand-levers. Each hand-lever is connected with its stem J, either directly by means of a pin P mounted on the upper end of the stem and projecting laterally therefrom into a slot m in the lever, or by means of an intermediate link Q, which is pivoted on the pin P and a second pin R projecting from the lever. Both forms are shown in Fig. l; the link-form in Fig. 2; and the pin and slot-form in Fig. 3.

Each hand-lever M is preferably provided on its free end with aknob m" exteriorly threaded to receive a threaded thimble 472?,

which holds in place a porcelain button m on which may be inscribed some designation indicating the purpose of the branch-pipe to which it belongs, as for example shower, spray etc. This however is not an essential part of the invention.

It will be readily seen that on depression of any handle M the corresponding stem J will be depressed and the cam-surface j thereof acting upon the roller h will draw out the valve Hand open the passageway of the nozzle a to the pipe' D, admitting the water or other fluid to the fixture served thereby. We do not find it necessary to provide special means for retracting the stems J, because this will be under ordinary cir cumstances performed by the unbalanced pressure acting directly on the end of the stem J and indirectly through the cam-surface 7', by the valve H; so that when released, the valves will close themselves unless the rollers h? are engaged by the notches 7' in which case a slight pull or jerk on the handle M will serve to release the valve.

To limit the outward movement of the stems J we may provide a screw-cap S screwed into a threaded hole a in the upper end of the post a as shown. This cap is omitted from Fig. 2 to illustrate the parts below it.

Our valve is adapted not only for use in the manner shown in Figs. 1 and 2, in which the liquid is admitted from the bottom and distributed from the sides, but also in the manner shown in Fig. 3, in which the liquid can be admitted'from the sides as well as distributed therefrom. In such case, as shown by the right-hand valve A, the liquid is admitted through the left-hand branch nozzle a by means of a pipe B. In such case, as it will ordinarily be desirable to make the feed-pipe bigger than the branchpipes, the valve-barrel O is removed from such nozzle and the joint made by means of the coupllng T. This, gives only three distributing nozzles, and consequently the lever M and stem J belonging to the intake nozzle are removed and the gland K replaced by a screw-plug U; a similar plug being of course inserted in the nozzle a WVhere more than four distributing nozzles are required, the valves can be connected together in series, as also shown in Fig. 3. At the left of this figure is shown a second valve 1 whose left-hand nozzle a is connected to the infeed-pipe B by means of the coupling T, and whose right-hand nozzle a delivers into the pipe 13 which is connected thereto by the coupling T. In such case, two of the levers M and stems J are omitted and two plugs U are used to replace the corresponding glands K. This arrangement gives five distributing nozzles if only two valves are used and additional valves may be added in like manner. It will be understood of course that where close connection between the valves is desired, the extra coupling T 2 and pipe B might be omitted and the coupling T join the two nozzles a directly.

We wish it understood that our invention is not limited to the use of all the above-described features and constructions, for some may be omitted and others may be varied or modified in various ways, as will readily occur to those skilled in the art.
