SPEQIFIGATION forming part f Letters Patent No., 694,880, dated March 4, 1902.
Application filed March 23, 1901. Serial No. 52,592. @lo model.)
.o @ZZ whom .it may concer-1c:V
Be it known that I, ENrns MUNGER, a citiin the countyl of Dallas and State of Texas, have invented a new and useful Stop and Waste Cock, of which thefollowing is a speciiication.
My invention is an improved stop and waste cock; and it consists in the peculiar'construction and combination of devices hereinafter fully set forth and claimed. I
In the accompanying drawings, Figure l is a central sectional view of a stop and waste cock constructed in accordance with my invention. Fig. 2 is a det-ail elevation of a moditied form of the valve. Fig.'3 is a detail sectional view taken through the valve-stem and bushing on a plane indicated by the line a o, of Fig. 1. v
The body 1 of the valve is of the usual form of a globe-valve, 2 being the connection of the main pipe, 3 the connection for the waterservice pipe, which is to be drained in cold weather to prevent freezing and the bursting of the service-pipe, and 4 beingthe usual web interposed between the said connections and having the valve-seat 5.
In one side of the body 1 is screwed or otherwise coupled a gland 6, which has the interiorly-,threaded portion 7, the waste-chamber 8, above the same, and a waste-port 9, which communicates with said waste-chamber, and as here shown is formed in a nipple 10, to which a-waste-pipe may be connected. The lower or inner end ofthe gland forms or is formed with a valve-seat 11, which isdisposed opposite the valve-seat 5. The said gland 6 is formed with a waste-channell on one side of its screw-threaded bore, whichY Waste-channel establishes communication between the service connection 3 and the wastechamberdS.
The stem 13, which operates in the gland -6 and has the screw-threaded portion 14,
which operates in the threaded bore of said gland,is provided at its lower end with the valves 15 16, which face in opposite' directions and are 'respectively adapted to engage thevalveseats 5 and 11. The said valvestem 13 is rotated bythe usual handwheel 17. Any suitable form of handle or a wrench may be employed in lieu of the hand-wheel for operatingl the ,valve-stem.`
0n the outer end `f the gland 6 is screwed a cap 18, in which the packing 19 is located and vent leakage around the valve-stem.
The operation of my invention is as follows: l
When the valve-stem is operated to open the. Vvalvel from the seat 5 and to close the valve 16 against the valve-seat 11 at the inner end of the gland,as shown in dotted lines in Fig. 1, the'water passes freely from the main Yto the water-service pipe through the connections 2 3, the body of the valve, and the port W'hen it is desiredA to cut oft 'the' or seat 5. service-pipe from the main pipe and to dian the water from the service-pipe to prevent the same from freezing, the valve-stem 1 3 is turned in such'manner as to cause the valve 15 to close Vthe' v port or seat 5. This also causes the valve 16 to open from the seat 11 at the innerY end of glandA G, and thereuponestablish communication between the wastey port 9 and the connection to the servicepipe, the waste ,Water-'passing from the latter through the waste-channel 12 into the wastechaxnber 8 and from'thence through the wasteportt), as'will be understood. Having thus described my invention, I claiml VIn a stop yand lwaste cock7 a body haring a main and a service connection, a port 5 between the same, and a threaded opening in one side, 'opposite said port, in combination with a gland having'screW-threads at its inner end to engage said threaded opening` and thereby detachably couple said gland directly to said body, said gland having a valve-seat 11 formed in its innerend, a threaded bore, a Waste-port, and a waste-channel in one side otfsaid threaded bore, said channelconnect'- ing said waste-port and said valve-seat 1l, a
valve-stem, carried by said gland, having a threaded portion engaging the threaded'bore of said gland, and an oppositely-faced valve at the inner end of said stem, adapted to alter' nately close the port 5 and the valve-seat 11, the outer end of said stem projecting through an opening in the outer end of said gland,
and a packing-cap screwed on the outer end of said gland, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
nNNrs MUNGER.
