UNIVERSAL COMPRESSION STOP AND WASTE COCK.

STEECIFICATION forming part of Letters Patent No. 751,869, dated February 9, 1904.

Application filed June 11, 1903,

To all whom it may concern:

Be it known that 1, WILLIAM G. NEWTON, or New Haven, in-the county of New Haven and State of Connecticut, have invented a new and useful IIHPIOVGIIXGIH] in Universal Compression Stop andWaste Cocks; andldo hereby declare the following, when taken in connection with the accompanying drawing and the numerals of reference marked thereon, to be a full, clear, and exact description of'the same, and which said drawing constitutes part of this specification and represents a view in vertical section of my improved cock shown closed to the entrance of'service-water'and open to the dischargeqof waste water.

My invention relates versal compression stop and waste cock, the object being to produce a simple, convenient,

effective, and reliable device which is constructed with particular reference to simplicity and durability.

lVith these ends in view my invention consists in acompression stop and waste cock having certain details of construction and combi- 2 5 nations of parts, as will be hereinafter de-Z scribed, and pointed out in the claim.

in carrying out. my invention as erein shown I employ a body 2 having its inlet and outlet ends 3 and 3 'provided with internal threads for the reception of the threaded ends of the service-pipes (not shown) of the servicewater system in which the cock is interposed. The said body is lso formed with an externally-threaded neck 4, located at a right angle to the said ends 3 and 3 and having its inner edge beveled to form an annular bearing-sun face 5 for the reception of a correspondinglybeveled annular bearing-surface'fi, forming the inner part of a shoulder 7, made integral 4 with and encircling a rotatable chambered head 8. The square outer edge of the said shoulder 7 is engaged by the inwardly-extends ing flange 9 of a union 10, which is internally threaded for being screwed upon the esternally-t ireaded outer end of t e neck 4. The said union 10 draws the beveled surfaces 5 and 3 together, these surfaces being fitted to form what is known as a ground-jointfl- "in setto an I improved uni-.

Serial No. 160,986. (No model.)

1 ting the cock to be usedin diflerent situations the chambered head 8 maybeturned in the body 2 so as' to occupy any desired relation thereto. Then when it has been set as desired the union 10 is-screwed down to'bring 'the beveled surfaces 5 and tact. This capacity for adjustment gives the 'cock its so-called universal. character. It will be perceived that in my improved cock no packings are necessary for this adjustment. The said body 2 is formed with a winding partition or web 11, which entirely separates its inlet end 3 from its outlet end 3, except for a water-port 12, formed through the'said partition 11, the outer surface of which is, formed with a slightly raised horizontally arranged valve-seat 13, forming the stop-valve seat of the cock and arranged concentric with the said water-port 12. This valve-seat 13 coacts with the washer-like stop-valve packing 14. The stop-valve packing 14 is located entirely within a cup-like casing 15, which is internally threaded to adapt it to be applied to the threaded stud 16, formed at the inner end of the spindle 17, which is furnished at a handle 18. The said casing 15 is formed at its outer end with a hub 19 the end of which engages with the squared inner face of a shoulder 20, formed upon the spindle at the base of the stud 16 thereof. Between the flat outer face of the casing 15 and the shoulder 20 of the spindle 17 I interpose a flat washer-like waste-valve packing 21, which coacts when the cock is open with the waste-valve seat 22, which is located at or near the bottom of a circular shut-oil chamber 23, formed within the inner end of the head 8. It will be observed that the pack ing 21 is just a trifle larger in diameter than the casing 15, which does not make any contact with the wall of the shut-oil chamber 23.

her 23 is slightly beveled, so as to act as a guide for the packing 21 when the same enters the chamber, at which time the service-water is entirely or nearly cut off from thewaste: pipe 27. If the packing 21 fits very closely within the shut-oil chamber, the service-water l wiil be completelv The inner edge of the lower end of the cham- 6 into close conits outer end with '95 (mt oil from the waste-pipe from the beginning of the opening of the cock up to the time of the seating of the packing 21 upon the seat 22 in the bottom of the shutoff chamber; but in any event the packing 21 will fit the shut-oil chamber so closely that the amount of water which escapes, if any, through the waste-pipe during the operation of the opening of the cock will be very inconsiderable. The Waste-valve packing 21, the cup-like casing 15, and the stop-valve packin 14 are all firmly held in place upon the threaded stud 16 by means of a nut 25 hearing against the lower face of the packing 14 and screwed upon the outer end of the threaded stud- 16. The said shut-ofi' chamber 23 is connected with the waste-chamber 24 by a large circular passage 26, formed in the head 8, which is provided with a waste-pipe 27, leading directly out of the outer end of the wastechamber. It is to provide for pointing this waste-pipe 27 in any desired direction that the cock is made with its so-called universal feature.

The spindle 20 is furnished about midway of its length with a heavy compression screwthread 28, which takes into a corresponding thread 29, formed within the outer end of the head 8, the said compression screw- threads 28 and 29 being located virtually above the path taken by the waste or service water in its passage through the waste-chamber 24 of the cock. At its outer end the chambered head 8 is externally threaded for the reception of a s'tufiing-box cap 30, containing a packing-washer 31, which is prevented from entering the outer end of the thread 29 by a fender in the form of a metal guard-ring 32, set into a recess 33, formed within theextreme outer end of the chambered head 8.

When my improved cock is closed, as shown by the drawing, its spindle is turned inward and downward, so as to force its stop-valve packing 14 firmly upon its stop-valve seat 13, whereby the direct passage ofany water from the inlet service-pipe through the body 2 into the house or system is cut ofi. At this time, however, any waste water from the house may enter the outlet end of the body and flow inward and upward over the packing 21 and through the shut-off chamber 23 and passage 26 into the waste-chamber 24 and out through the waste-pipe 27. To open the cock for the inlet of service-water, the spindle is turned outward, with the effect that almost imme diately after the packing 14 lifts away from the seat 13 the packing 21 enters the shut-ofl chamber 23, so that the entrance of water into the chamber 24 is entirely or substantially cut ofi' prior to being completely out off by the forcing of the packing 24against the seat22, which, so to speak, closes the waste.

I particularly wish to point out that when the cock is tully open the packing 22, the casing 15, and the packing 14 are all Virtually has been removed from the body as described,

the stop-valve packing .14 and the waste-valve packing 21 are fully exposed and may be replaced, if desired, without in any way dis.- turbing the spindle 17 or, indeed, by doing anything more than to remove the nut 25 and the casing 15. This provision of ready access to the packings without disturbing any part of the valve is a point of great convenience. v

It is apparent that in carrying out my invention some-changes in the construction herein shown and described may be made; I would therefore have it understood that I do not limit myself to the exact construction shown, but hold myself at liberty to make such departures'therefrom as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a compression stop and waste cook, the combination with a body containin a valveseat and furnished with an external -threaded neck having its inner edge beveled toform an annular bearing-surface, of a. chambered head having a circumferential shouldcrformed with a beveled bearing-surface meeting with the bearing-surface before mentioned 11) form a ground-joint, and the said head being formed at its extreme inner end with ashut-ofi chamher, with a valve-seat located at the bottom of the said shut-oi! chamber, with a waste-chamber, and with a pasmge leading from thesaid valve-seat to the said waste-chamber; a wastepipe leading out ofthe said waste-chamber, a, spindle mounted in the outer end of the said chambered head, a stopvalve packing carried by the spindle and ooacting with the valveseat in the said body, a wastevalye p cking carried by the spindle and coacting' with the side walls of the shutofl chamber and with the valve-seat at the bottom thereof, and a union-nut applied to the neck of the body and coacting with the shoulder of the chambered 7 head for drawing the said two beveled bearing-surfaces into contact, whereby when the cock is open the packings are located within and protected by the shut-ofl chamber.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

WILLIAM G. NEWTON.
