STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 319,157, dated June 2, 1885.

Application filed December 26, 1884. (No model.)

To all whom it may concern.-

Bc it known that I, DnvrD Wriirnnonn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stop and Waste Cocks; and I hereby declare the following to be a full, clear, and exact description of the saine.

My invention relates to the class of devices ordinarily employed in connection with the water-supply in houses for the purpose of permitting in the winter-time the supply to be shut-off, and allowing in this operation water already within the pipes to escape in order to avoid freezing therein.

My present device is designed particularly for use in connection with the water-supply of houses arranged to be occupied as iiats,7 each of which iiats is supplied by a separate branch leading from the service-pipe connected with the city main, to afford to the occupants of cach independent s control of its water-supply. Owing to this construction and arrangement of tenementhouses, the rod hitherto commonly used for shutting off the water, particularly in cold weather, to prevent its freezing in the pipes, cannot be employed owing to the ordinary location in lats, as at present constructed, ofthe sinks, and, even if this reason did not exist, for the obvious reasons, besides the one that after comparatively few operations it fails to work satisfactorily, that it would have to project through the apartments below the one from which it is operated, presenting therein an unsightly appearance, and if used at all it could only be employed in the lowest story.

I am aware that various devices devoid of rods and resembling my present improvement, and for a similar purpose, are in use, but, owing to their construction, particularly in the matter of the operation of their valves, produce unsatisfactory results and prevent ready access for the purpose of repair to their internal parts whenever these shall get out of order.

I am also aware that devices constructed somewhat similar to my present apparatus are in use as stop and waste cocks, and as hoppercocks in water-closets.

It is my object to afford a device for the ripe,

purposes above stated in which the valves shall operate accurately and readily to accomplish their work, and to this end my invention consists in the particular construction and combination of the parts forming my improved stop and waste cock.

The drawing represents a vertical section of my improvement, showing its internal construction, having a part broken away to per- 4mit the representation upon the sheet of operative features.

A is a vertical pipe,having a diameter preferably of about one and onequarter inch, and provided on its upper side with a perforated cap, t, screwed upon it, and from which `cap an upward-projecting bracket, s, extends.

s, and provided toward its opposite extremity with a weight, o.

G is a vertical rod pivoted at its upper extremity to the rod or bar I3, and extending through the perforated cap ,to hang centraL ly within the pipes A and A',and pass through the perforated valveseat q. A valve, D, is adjusted upon the rod C, toward its lower extremity, to lie below the valve-seat Q, and is maintained in position from its upper side by means of a suitable nut, n. The lower extremity of the rod C is screw-threaded and adjusted into the vertical part of an `angular arm, B', lying within a horizontal pipe, E, preferably of the same diameter as the pipe A.

F is a ball-valve having a seat within a chamber, m, formed upon the pipe E, and connected with the extremity of the horizontal portion of the bar B by means of its stem Z.

G is the waterinlet pipe, connected by means of a coupling-joint, k, with the valve-chamber m, and through which connection of the dewater-main in the street is effected.

vice with the service-pipe leading from thek ICO H is the water-supply pipe, attachedy by means of the coupling?? to the pipe ,E,which forms the body of the device, andsupplying water to the fixture to bc supplied in one of the flats of a building.

The operative position of the device when used as a stop and waste cock, as shown in the drawing, is underneath the ground, in which' it is buried to the lower extremity of the bracket s. The weight o operates to 'maintain'jthe valve F upon its seat and prevent ingress of water into the pipes E and H, the pressure of water upon it serving to pack it firmly in Iits position, and its effect upon thervalve D, which is connected by means of a stiff joint with the valve F, is to maintain it-away from its seat q. These are the normal positions of the valves produced by the downward pressure of vthe weight o upon the rod c, and which are produced to shut off the water-supply throughlthe medium of the valve F, as hereinbefore stated, and permit the escape in winter,`to prevent its freezing,of water contained in the supply-pipe H, by way of the pipes E and A', through the waste-outlet p,which may lead into the ground or be connected with the sewer.

- The relative positions just described of the valvesD and F, though normal, owing to the iniiuence upon the valves of the weight o,wi1l only be sought occasionally, and particularly in freezing weather, to permit the suppl ypipe H to be freed of its contents, the ordinary position of the valve D being against its seat,up on whichit is packed by the pressure of water from underneath, and of the valve F above its seat. The relative positions of the valve last named are effected by a crank, I, conveniently located in the story supplied through the pipe H, and connected from its extremity with the end of the horizontal bar B through the medium of a :suitable cable, which may, if desired,` pass over pulleys. The lever I is bent, as shown, and pivotally attached toward its lower extremity to a suitable support,and provided at its opposite extremity with a weight, g. When the weighted crank I is raised to the positionv shown by the full lines representing it in the drawing, it will be maintained in such position against the pin f, forming a stop by the gravity of the weight o, the arrangement being such that when the crank is adjustedin position the ball-valve F will rest upon its seat and the passage from the supply-pipe H.

to the waste-outlet p will be opened; or, in other words, to use the common expression for this operation,the water is shut off.77 To turn it on77 the valve F is raised from its seatand the valve D adjusted upon its seatV by turning the weighted crank I slightly away from the stop f, when it will immediately fall. to the position in which it is shown in dotted lines in the drawing. raising the weighted end of the rod B, and with it, through the medium. of the vertical rod C, the valves. Owing to the rapid fall of the weighted end of the crank I, in assuming the position shown in dotted lines, water entering the pipe E through the chamber m. cannot reach theI under side of the valve.` D before the latter shall have been raised to its seat, and when it shall once have reachedfthe last-named position the pressure of water from underneath will serve to pack` -it the vmore tightlyto prevent the entrance of water into the pipe A, wherein, if it should enter in quantities sufficient to cause it to rise toward the top, it would be liable to freeze and obstruct the operation of the device.

The particular advantage afforded bythe crank 'mechanism I, hereinbefore described,

`consists in the fact that thereby a difiiculty is overcome which, as far as I am aware, attends theyuse of all stop and waste cocks similar in Y ed, generally forbid the use of stop and waste cocks which permit, even in a small degree, constant waste of water. In devices at present in use having connected valves'operated simultaneously to control the outletor waste and the inlet or supply7 of water, and fin which the operation of shutting ofi` or turn# ing on the water is performed through the medium of a cable, the length of which is accurately measured to permit one valve to fit closely upbn its seat while its companion valve is removed a certain distance from its seat, and to cause the latter, byadjusting it through the medium of the cable a certain prescribed distance, to iit upon its seat,where by the former is removed thesame distance from its seat, continual waste of water occurs after such device'has been in use for a `short time. This is due to the `fact that the weight provided upon the lever, which weight tends to maintain one valve upon its seat, and the lifting of which, through the medium of the cable, reverses the positions of the valves with relation to eachother, produces a constant strain upon the cable, and stretches it' more or less, of whatever material it is composed.v

The prescribed distance of adjustment of the valves is insufficient to bring that controlling the waste snugly against its seat, and thus an opening is provided which permits continual iiow through it of water from the servicepipe- By providing the weighted crank I this difficulty is completely overcome, since its pla in a downward direction is controlled by the length of cable in excess of what is required to permit the valve controlling the supply, when originally adj usted, to rest firmly against its seat. In other words, f as the cable becomes lengthened by stretching, whereby the valve D would not otherwise, by raising it IIO the distance prescribed in adjusting thede-V f vice, be brought aga-inst its seat, the weighted crank I will fall as far below its position (shown by dotted lines in the drawings) as shall be necessary to make up for the increasing length of cable.

The various couplings,hereinbefore referred to and shown in the drawings, afford, owing to their particular arrangement, ready and convenient access to the internal parts of the device, which ordinarily require most frequent repair.

TW'liat I claim as new, and desire to secure by Letters Patent, is-
