REVERSIBLE COMPRESSION STOP AND WASTE.

Specification of Letters Patent.

Patented ow. 20, 1908.

Application filed. August 13, I907. Serial No. 388,343.

To all whom it may concern:

Be it known that I, WILLIAM G. ROWELL, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Reversible Compression Stops and Wastes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improve ments in reversible compression stop and waste for the use of plumbers in the equipment of buildings with water circulating systems. Devices of this sort are utilized for the purpose of turning the supply of water off and on, and in my improvement I provide two diametrically opposite exit nozzles for the waste water one of which is always closed by means of a screw or plug, so that when the workman has installed the device he plugs up the nozzle which points in an improper direction leaving the other nozzle to take care of the waste water. Also, in my present improvement, I control the discharge of the waste water by means of a loose waste collar which is capable of both vertical and rotary movements, the result being that the collar washes itself by keeping all foreign substances in constant motion so that they will be readily discharged through the exit nozzle.

In the accompanying drawing Figure 1 is a sectional elevation taken longitudinally through the stock, or, in other words, on the line 9 of Fig. 2Fig. 2 a cross section on the line it of Fig. 1, and Fig.3 a detail plan view of the waste water collar.

Similar numbers of reference denote like parts in the several figures of the drawing.

1 is the stock proper which is open at the ends, as seen at 2, 3, for communication respectively with the water su ply and service pipes. This stock 1 is divi ed in the usual manner at its central portion by a partition 4: which has a horizontal portion through which is formed a valve opening 5 which latter is the sole means of communication between the respective ends of the stock.

Formed integral with the stock and extending upwardly therefrom is a casing 6 which is open at the top and is interiorly threaded at its upper portion. The lower part of the casing constitutes a waterway chamber a, and an opening 7 is formed in the floor of this waterway whereby communication is established between the latter and that end of the stock to which the service pipe is connected.

8 is a cap having a reduced threaded plug 9- which is driven within the threaded end of the casing. A recess 10 extends from the bottom of the plug up into the body of the cap andis interiorly threaded, and an opening 11 extends from the top of the cap into said recess. Through the opening 11 extends the valve spindle 12, and 13 is a gland surrounding the spindle and driven on the top of the cap 8 and inclosing any suitable packing 14. This spindle has threads which engage the threads of the recess 10, the top of the spindle being provided with any suit able handle 15 for the purposes of convenient operation. in the usual manner. The spindle 12 extends down through the waterway at the lower portion of the casing 6 and has secured to its lower end an ordinary valve 16 which is surmounted by a washer 17 that extends slightly beyond the periphery of the valve. The valve is of such dimensions that it will freely pass through the opening 7 but the washer has substantially the same diameter as that of the opening and will completely fill the latter when drawn up into the same.

Loose around the spindle 12 and contained within the waterway in the lower portion of the casing is a waste water collar 18. This collar is cup-shaped and is perforated in the bottom, as seen at 19, so that the spindle 12 may pass therethrough, the shape of this opening being polygonal so that water passages are provided, as seen at 20, at the angular portions of said opening immediately outside the spindle, by means of which passages communication is established between the service pipe and the water way inside of said Collar. In the sides of this water collar are ports 21, and the collar itself is loose around the valve spindle and is perfectly free in the waterway within the lower portion of the casing so that it will be clear that said collar is capable of free vertical and rotary movements.

22, 23, are exit nozzles which extend'from diametrically opposite points of this casing 6 and communicate directly with the waterway in the lower portion of said casing so that it will be clear that water passing through the collar 18 will be discharged directly through these nozzles, any suitable plug 24: being provided whereby one or the other of these nozzles may be closed as the occasion may demand.

The operation of my improvement is follows z-JVhen the valve is elevated to permit the delivery of water from the supply into the service pipe, as shown at Fig. 1, the washer 17 will be drawn up into the opening 7, thereby completely cutting off communication between the waterway in the bottom of the casing and the service pipe, so that there can be no discharge of water through the nozzles 22, 23. hen the valve is seated against the valve opening 5, as shown at Fig. 2, all communication between the service and supply pipes will be closed, and there will be a direct communication between the service pipe and the waste water collar 18, and the water in the service pipe will then pass through the opening 7 and the openings in the bottom of the collar outside the valve spindle, and be discharged through the ports 21 in the collar into one of the nozzles 22 or 23.

In installing my improvement either one of the nozzles may be plugged, as the occasion may demand, thus leaving the open nozzle to take care of the waste water.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent isz- In a device of the character described, the combination of a stock open at the ends for connection with supply and service pipes" is controlled, a casing integral with said stock and within which said valve stem is operatively mounted, said casing having a waterway chamber which is in communication with the service portion of said stock independent of said valve opening and also having diametrically opposite exit nozzles leading direct from said chamber into the outside air, a plug for closing one of said nozzles,'a waste collar loose around said valve stem and loosely confined within said waterway chamber, said collar having inlets in its lower portion and outlets in its side, and a washer surmounting said valve and of such shape and dimensions as to entirely cut ofi communication between said waterway and service portion of the stock when the valve is opened, whereby the depression of said valve will allow the water in the service pipe to enter the waterway chamber and waste out through one of said nozzles.

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