RECIPEOCATING-PLUG FAUCET.

Application filed June 18, 1921." Serial 110 478553 To all whom. it may concern Be'it known that I, HENRY G. CORDLEY, a citizen of the United States, residing at Glen Ridge, in the county of Essex, State of NewJersey, have invented certain new and useful Improvements in Reciprocating- Plug-Faucets, of which the following is a description, reference being had to the accompanying drawings, forming a part hereof. 4

My invention relates to faucets of the reciprocating plug, spring actu'ated type and has for its object to provide a faucet of this type which will be simple and inexpensive in construction, will be self-closing and at the same time adapted to be held open if desired, will be easily taken apart for cleaning or replacement of'worn parts,.will not readily get out of order and :will be effective in operation.

With the above described objects, and other objects hereinafter explained'in view my invention consists in the construction and combination of elements hereinafter, de scribed and claimed.

Referring to the drawings; H

Figure 1 is a central vertical longitudinal sectional view of a faucet embodying my invention, showing the faucet closed. V

Figure 2 is a view similar to Figure 1 but showing the faucet open.

Figure 3 is a side view of a portion of the means for opening the faucet and holding it open, the parts being shown in tlieposition which they assume when thefaucet is closed. M

Figure 4 is a view similar to Figure 3 butshowing-the parts in the position which they assume when the faucet is to be held open. I

Figure 5 is an end view of thefaucet.

Figures '6 and 7 are views showing the packing ring in vertical seetion and in end view respectively.

In the drawings 1 indicates'the inner member of the faucet casing consisting of a piece of straight tubing serewthreaded in its rear portion as shown at 2 to receive a nut 3 on the outside of the wall 4 of the tank from whichliquid is to be drawn, and a nut 5 on the inside of the wall 4, these nuts bearing against gaskets 6 and Z respectively, of rubber or other material adapted to be compressed to prevent leakage about the tube 1 where it passes through the' usual faucet opening in the'wall 4-.

8 indicates the outer member of the faucet casing also .formed of a straight piece of tubing, having an abutment 9 formed at its inner end adapted to fit over-and be secured on the forward end'of the inner casing member 1. Near'its rear-end this'outer casing member has formed in its under side a discharge opening 10, and it is internally screwthreaded at its forward end as shown atll. I V.

l2 indicates a cylindrical plug valve which fits withinand is adapted to reciprocate in the outer casing member 8. This plug valve is carriedbya valve rod 13 'the inner end of whichis preferably connected by a ball and socket joint with the. plugasshown. This valve rod extends througha central opening in a cap 14 which is externally screwthreaded at its inner end to engage the screwthread ll'of the outer casingmember 8, and carries onitsouter end a double cam by means of which the plugvalve is drawn outward when the valve rod is rotated as hereinafter described.

The. double earn consists of fixed cams 25 and 26 formed in a cylindrical shell extending'forward from the head of the caplet, the two cams being identical in shapelbut oppositely arranged with referenceto the axis ofthevcap, each extending from a point 27 near the head of the cap to a point 28 at 'a distance from the head of. the cap corresponding tothe distance through which the plug valve is to be .moved. The valve 13od 13 is provided on:opposite sides -with radially extending ,lugs and 31 the rear faces of which, that is the faces toward the cap 14, are flat and in a plane at right angles to the axis of the valve rod. Attheir outer points, 28 thecams are out off in a plane at right angles to the axis of the cap so as to form ledges 32 on which the lugs 30 and 31 carried by the valve rod may rest and from which they will not tend to slip off. From the ends of these ledges 32 the shell in which the cams are formed iscut away on lines parallel with the axis of the cap to the points 27.

The plug 12 has formed in its outer end an annular recess 17 to receive the inner portion of an expansion coiled spring 18 the outer portion of which is received in the inner end of the'cap 14, the spring thus bearing at one end against the plug 12 and at the other end against the headofthe cap 1 1 and acting to separate the plug andcap, "forcing the cap inward against its seat.

On the valve seat i ormedby, the inner end of the innerfcasingmember ljis arranged a:

' packing ring 20 which may be oii wood or any Y ner casing member. When itis desired to remove a packlng ring all that is necessary,

1 the cap l lbeing unscrewed. and removed with the ping 12 ;is to insert rod of suitable diameter through the rear end of the inner casing member 1 and push the packing ring out through the outer casing member, or, by

means of a suitably hooked instrument, to reach in through the outer cas ng member n afte gag ng s ook wi he Il11g'2' 9,

and draw itou't with the ring 20,

v rod' 13 with the plug 12, as shown; is provided'byiorming centrally of the, outer end of the pluga recess adapted to receive the ball shaped head 36 formed on the inner end of the valve rod. and forcing the walls of the i v recess; between itand the annular it may be rotated;

against the packing ring 20 and closing the recess; 17, inward to enclose the head. 7 The valve rod13is provided at its outer or forwardendwith a cross WVhen it is desired to open the faucet the parts being in the position in which'they are shown in Figure 1,"with' the lugs 30 "and31 resting at the points 27 and the spring 18'be ing in expanded position forcing the plug 12 discharge'opening' 10, by rotatingthe valve rod 13 by meansof the crossbar 37 the lugs 30 and 31 are caused to travel outwardon the cams 25 and 2 6 drawing the plug 12 out; 7

Ward against the resistance of the spring 18 away from its 'seat and away fromthe'dispiece 37 V by which charge opening 10, permitting liquid to How freely. When the lugs 30 and 81' reach the ledges 32the plug will be fnllywithdrawn.

If ityisdesired'to'have the faucet remain open the lugs 80 and" 31 will be allowed to rest on the ledges froinwhich theywill not readilys lip off their under or'rear faces being in a planeat right angles to the axisof the ledges which are alsoin a plane at right to hold the lugs against the ledges. When itis desired'to have the faucetclose, the valve nd e e edtili'e r direct on su e e t y to v th lug Ofi llel g If e-va ve d is r ta o he rig t th ug il pas over theedges of the ledges and loedmawn rearward at once tov the points- 27, the; plug angles to theaxis and the spring 18 acting being forced rearward against-its seat. If

Having thus described my invention what I claim is; r 7 7 v In a reciprocatingplugfaucet, the combination with an outer casing member having Y The ball and socket-connection of the valve a valveseat at its: rear'end and 'a discharge opening-in its side, of a plug valvelfitting sa d outer. cas ng member andadapted to re ciprocatetherein and to close thedischarge opening, a cap secured on the outer end of from the cap aledge'ina :plane at right a-ngles with the axis of casing, and oppositely arranged radially extending lugs carried by" the valve rod in position ,tobear against said cams, each of said lugs having its inner face fiat 'and'in a -plane at right angles with the axis of thevalve rod adaptd to heldf-"onsaid ledges by said expansion spring.

In testimony whereof I affix my signature this thirteenth day'of June 1921.
