STOP AND WASTE 000K. y No. 354,148. Patented Dec.` 14, 1886.
rTnn STATES JOHN Hi. JOHNSON, OF CHICAGO, ILLINOIS.
STOP AND WASTE COCK.
SPECIFICATION forming part of Letters Patent No. 354,148, dated December 14, 1886. Application filed July ll 18864 Serial No. 206,879. (No modell) To all whom it may concern:
Be it known that I, JOHN H. JOHNSON, re-
` siding at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Im provement in Stop and Vaste Cocks, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a side elevation; Fig. 2, a vertical longitudinal section with the valve closed 5 Fig. 3, a vertical longitudinal section -with the valve open; Fig. 4, a detail in section showing the waste-port open; Fig. 5, a detail in section showing the waste-port closed; Fig. 6, an elevation of the valve.
This invention has for its object to improve the construction and operation ot" stop and waste cocks by giving the valve a positive movement to open the supply and shut Off the waste,and a return movement to close the supply and open the waste, and 'to connect the several parts forming the valve and shutoff one with the other to leave each part independent of the other and at the same time have all the parts to work in unison, and to have the valve and shut-ofi maintain their proper relative posit-ion one to the other to perform their respective offices as the parts become worn, and its nature consists in the several parts and combinations of parts here` inafter described, and pointed out in the claims 21S DEW.
In the drawings,A represents the main shell, Ofacylindrical shape on the exterior,as shown, and with an interior cylindrical chamber. One end of the shell is provided with an external screw-thread, a, to receive a stuffing-box or cap', and the other end is provided with an interior screw-thread, c, for attaching the shell or case to its continuation or base.
B is the inlet-port formed with the shell A, its opening communicating with the interior chamber of the shell below the valveseat, and, as shown, this inlet-port B is provided at its ends with an external screw-thread for attachment to the supply-pipe, as usual.
C is the outlet-port formed with the shell A, with its opening communicating with the interior chamber of the shell A above thc valvesea-t, and, as shown, this port at its end is provided with an external scrcwth read, c, for connection with the waste-pipe.
D is a dange located on the interior of the chamber A, and having an edge formed to act as a valve-seat, d.
E is a head of a circular form and a diameter to pass through the opening therefor in the flange or wall D, and this head is provided with an extension or stem, c.
F is a head corresponding` in diameter, or nearly so, to the head E, its diameter being one to allow the head to pass through the opening in the wall D, and this head F is connected with the head E by barsf, between which are openings f.
G is a rubber or other valve located around the stem E, and supported on the stem by a cup, g, in the form ot' construction shown, the valve being so formed as to properly seat on the edge d of the flange or wall D and close the Opening for the supply.
H is a coiled spring, the lowerend of which is contracted so as to leave an opening, h, to receive the end of the stem c, which extends below the cup g, which opening forms a guide for the stem to maintain the valve G in proper relation to be seated and close the opening in the Wall or flange D.
I is a base or extension having a closed bottom and an interior chamber in which is lo` cated the spring H, and the upper end ot' this base I has a ange, t', to coincide with the lower end of the shell A, and its extreme upper end is provided with an external screwthread, fi, to receive the screw-thread a', and connecting the shell A and base I one to the other.
J is a stem, the upper end of which is screwthreaded for connection with the operating arms or levers by which the stem is moved, which levers or arms are not shown,as they may be of the usual construction of such parts for use with a water-closet seat. The inner end,
j, of the stem J is of less diameter than the body vot" the stem, and enters a hole in the head F, the endg` being circular and the hole therefor in the head F corresponding in diameter there to, and the stem J is also provided near its inner end with a tlange or rim,j, which tits the interior chamber of the shell A.
K is a packing, of leather or other suitable IOO material, located around the endj of the stem J, below the flange j'. and corresponding in diameter to the diameter otA the lange, and this packing K, when the stehn J is down, rests on a wall or iiange, k, formed within the ohamberot' the shell A, which wall is provided with a hole corresponding in diameter, or nearly so, to the diameter of the head F, so as to allow such. head to pass through the hole. and the packing K closes the hole in the wall or Hange k when the stein J is 'forced down.
L is the waste nipple formed with the shell A and located to have communication with that portion of the chamber ofthe shell A above the fiange or wall 7c, and opened or f closed by the movement ot' the stem J through the packing K. The nipple L is provided with an external screw-thread, Z, for connection with the Wavre-pipe, the connection not being shown,bnt being the usual construction for stop and waste cocks for use with water` m, which packing makes a tight joint between the stuffing-box and shell and prevents any escape at thatpoint.
The parts are assembled by placing` the valve- G on the stem e and securing it thereto and against outward spread by the cup g. The heads E and F, with the stem e and connecting-bars f, can be cast or formed from' a single piece, and these heads, with the valve G, are inserted in the interior of the shell A to have the end of lthe valve G engage the seat d when the valve is closed. The spring H is dropped into the chamber of the base I, and the end of the stem e inserted in the opening h of the spring, and the base secured to the shell A by the screw-threads a and i. The packing K is placed around the endj of the stem J. and the stem and packing inserted in the opening or the chamber ot' the shell A, with the end j entering the hole in the head F,and the stuffing-box or cap M is then screwed down to place, closing the end ofthe chamber and completing the device ready forv use.
In use the forcing down ot' the stem J by the action of the water-closet seat or other-v l wise, carries down the packing K to close the water to pass in' from theJ inlet B to the chainber ofthe shell A and out lthrough the open ling of the outlet O to the bowl, as usual, and
when the pressure is released on the stem J the spring H, in connection with the force of the iniiowing water. acts to close the valve G tightly onto the seat d ofthe flange or wall D, shuttingr oft` the tlow of water into the chatn ber ofthe shell, and at the sante time the packing K is carried up to open-the nipple L, and the opening in the Wall or flange la allowing the water to pass through the waste-pipe, as usual.
The connection of the valve with its closing-springH, through the end of the sten c entering the hole h, formed by the end of the spring, allows acertain amount of-free play between the spring and valve for the valve to seat properly without interference from the spring, and the connect-ion also keeps the valve and spring properly centered for performing the work required ot' each. The con-A to operate without affecting the operation of the valve, and this connection allows of adegree ot' end movement for both the stem and the valve, by which both devices will work` effectnally in case of wear, and it also maintains the proper lineot movement between the valve and the stem for the stem to operi the other an accurate fitting of the parts to work vproperly is not required, as is the case where the stem and valve are made continu- ICO ous without any disconnection between them.
What I claim as new, and desire to secure by Letters Patent, is-
l. The combination of the movable stem J, having the bottom extension or end, j, with the head F, having an opening for the reception of said extension, the connecting-bars f,-head E. stem e. valve G, and spring H, substantially as herein set forth. I
2. The heads E F, connected by bars f, with openings j" between them. and stem e, in cotnbination with a valve, G, spring H, and stem J, for opening and closing the valve, substantially as specited.
3. Astop and waste cock consisting of the shell A, inlet-port B, outlctport C, Wall D, with valvesea: d, heads E F, connected by bars f, stem e, valve G, spring H, base I, stem= J, packing K, wall k, and waste-nipple L, all constructed and operat-ng substantially as and for the purposes specified.
