CHECK AND WASTE COCK.

SPECIFICATION formingpart of Letters Patent No. 722,419, dated March 10, 1903.

Application filed December 3, 1902. Serial No. 133,707. (No model.)

To all whom it may concern:

Be it known that I, WILSON F. BRUNT, a citizen of the United States, residing at Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Check and Waste Cocks, of which the following is a specification. 7

My invention relates to check and waste cocks or valves of that type which are commonly employed in plumbing systems to control the supply of water to the water pipes and faucets of dwellings and other buildings.

' In practice these cocks are usually interposed in the water-inlet pipe or pipes in the basements of buildings, at or near the pointwhere the pipe rises in the basement. The object of these cocks, as is well understood by plumbers and others acquainted with the art, is to cut ofi the supply of water at such times as there may be danger of freezing the water in the house-pipes, and consequently bursting the latter, and in order to drain 0% the water standing in the house-pipes the cock is commonly provided with a small waste or leak port, which is brought into operation simultaneously with the cut-off of the main supply. These cocks as hitherto constructed have usually been provided with a turning-plug hav ing a main passage transversely therethrough for the passage of the water-supply and further provided with a small leak-passage at right angles to and tapping the main supplypassage, which leak-passage when the cock is turned to cut off the supply brings the housepipe into communication, through itself and the main supply-passage of the cock, with a small leak-port in the valve-casing. In all of the cocks of this character with which I am acquainted this interruption of the supply and simultaneous draining of the housepipes is effected by giving to the plug a quarter-turn, and in order to prevent an over throw of the plug the latter is commonly provided with a laterally-extending pin cooperating with a pair of stops on the casing situated ninety degrees apart. It has been found in practice that the pins employed to limit the turning of the cock to a quarter-circle frequently break-off, resulting in the careless turning of the cock either short of or beyond the intended extent, which results in either defeating the draining effect or throwing the supply side of the cock into communication with the drain, thus wasting the supply.

My invention has for its primary object to eliminate all possibility of such mistakes arising from an improper manipulation of the valve through the provision of a construction of cock or valve which is not dependent upon the turningof the plug to any particular predetermined extent, but which, after the plughas been turned sufficiently to fairly and fully cut off the supply, will insure the drain effect on the house-pipes until the plug is again turned back or around into communication with the supply, such a construction obviously dispensing with the provision of stop-pins and the like, and consequently obviating also the evils, above referredto, which arise therefrom.

A further object of my invention is to simplify and cheapen the construction and production of devices of this character by a reduction in the number of operating parts hitherto required to be assembled in the production of a complete device.

To these and other minor ends my invention consists in a check and waste cock of the character indicated having the peculiarities of construction and novel mode of operation substantially as hereinafter more fully described, and pointed out in the claims.

In the drawings, which show my invention in a preferred embodiment thereof, Figure 1 is a central vertical transverse sectional View showing the cock in supply position. Figs. 2, 3, and 4 .are horizontal sectional views on the line 00 a; of Fig. 1, illustrating the cock in three different positions of control; and Fig. 5 is a transverse. sectional view on the line 5 5 of Fig. 1, illustrating the webbed construction of the turning-plug.

.Referring to the drawings, 6 designates a cone-shaped valve-casing, having formed integral therewith on opposite sides and adjacent its upper and lower ends, respectively, a pair of eXteriorly-tapered tubular extensions 7 and 8. The conical bore of the casing 6 extends entirely thcrethrough, and in the wall of the casing, near its lower end and substantially in the horizontal plane of the lower lateral inlet-opening 9 from the tubular extension 8, are arranged a series of small radial ports 10.

Fitting within the conical bore of the main body 6 of the valve-casing is a correspondingly-shaped turning-plug 11, provided with a vertical stem 12 and a thumb-piece 13 for turning the same. The body 11 of the plug opposite the orifice 1a of the outlet tubular extension 7 is annularly recessed, as shown at 15, and this annular chamber communicates with a lower axial vertical bore 16 through radial passage-ways 17,1ying between the elements 18 of a spider, which integrally unites the upper and lower halves of the turning-plug. The axial'bore 16 at its lower end terminates in a short lateral extension 19, leading to the outer surface of the plug, this radial extension 19 being horizontally coincident and preferably vertically and laterallycoextensive with the orifice 9 of the inlet-passage through the tubular extension '8, as plainly shown in Figs. 1 and 4.

Integral with or set in the lower end of the plug is an externally-threaded depending extension 20, adapted to receive an annular washer 21, contacting the lower end of the valve-casing, and a nut 22, whereby the desired fit of the plug in the casing may be readily secured. It will be understood that the tubular extension 8 is designed to have soldered or otherwise connected thereto the meeting end of the supply-pipe leading underground from the main, while the tubular extension 7 is adapted to similarly connect with that portion of the same pipe which extends through the basement and connects with the various water-supply branches throughout the building.

Describing briefly the operation of the cock, when the plug is in the position shown in Figs. 1 and 4 the lower lateral extension 19 of the main axial bore 16 of the plug is in full register with theinlet-orifice 9 of the inlet tubular extension 8 and the water flows upwardly through the axial bore 16 of the plug through the passage ways 17 between the arms 18of the spider into the annular cham ber 15 and thence into the tubular extension 7, the orifice 14 of which is always in communication with the annular chamber 15 whatever may be the position of the plug. In this position the solid portion of the wall of the lower end of the plug cuts off all of the waste-ports 10. When now it is desired to cut ofl the supply and drain the house-pipes,

the plug. is given a turn to one side or the other of the supply position, the eifect of which is at first to completely cutoff the supply, as shown in Fig. 3, and immediately thereafter, as illustrated by Fig. 4, to place the'extension 19 of the axial bore 16 of the plug into full registration with one or into partial register with two adjacent waste-ports 10, and this communication of the radial port 19 with one or two of the waste-ports will always be maintained until the plug has been turned entirely around into registration again with the supply. When the bore of the plug is thus in communication with any one or more of the waste-ports 10, the water standing in the house-pipes is of course free to flow backwardly and drain off through said wasteports. It is desirable to preclude in the construction of the device the possibility of placing the supply at any time in communication with any one of the waste-ports. To this end the two waste-ports lying immediately on either side of the supply-orifice" are each located at a distance therefrom very slightly greater than the width of the radial port 19 of the plug; but this distance is so slight as to be practically negligible inwconsiderin g the movement of the plug, and it may therefore be said that the'movement of the plug'is such that so soon as it fairly cuts 03 the supply it opens-the house-pipe to the waste. In practice persons manipulating these valves'have become accustomed and trained to give the plug at least a quarter-turn, which in the case of my present inventionwouldmore than suffice to cut off the supply and establish communication with the waste; but whereas in the former devices a turning of the plug nearly or quite half-way around through the breaking 0d of the stop-pin has resulted in placing the supply in communication with the waste no such accident can occur in my device, since the supply cannot in any position of the plug be thrown into communication with the waste.

. I do not limit my invention to the precise form and construction thereof hereinabove described, and shown in the drawings, since it is obvious that the particular embodiment herein shown might be considerably varied without departing from its underlying principle and without sacrificing the advantages over the prior art hereinabove enumerated that are secured thereby.

I claim- 1. In a check and waste cook, the combination with a valve-casing having inlet and outlet ports and a plurality of waste-ports, of a ported turning-plug in said casing the port whereof has a single inlet-orifice which, when turned out of registration with the inlet-port of the valve-casing, is immediately thereafter brought and maintained in communication with one or more of said waste-ports in all positions of the plug, substantially as described. V

2. In a check and waste cock, the combination with a valve-casing having inlet and outlet ports located at difierent heights thereon and a plurality of waste-ports located on each side of and opposite said inlet-port, of a ported turning-plug in said casing having an outlet-orifice in continuous communication with the outlet-port and an inlet-orifice which, when turned out'of registration with the inlet-port of the valve-casing, is immediately thereafter brought and maintained in communication with one or more of said wasteports in all positions of the plug, substantially as described.

3. In a check and waste cook, the combination with a valve-casing having inlet and outlet ports located at different heights thereon and a plurality of radial waste-ports located on each side of and opposite said inletport, of a turning-plug in said casing having a longitudinal bore terminating at its upper end in an annular chamber in constant communication with said outlet-port and at its lower end in a radial extension which, when turned out of registration with the inlet-port of the valve-casing, is immediately thereafter brought and maintained in communication with one or more of said waste-ports in all positions of the plug, substantially as described.
