Application filed September 2, 1915. Serial No. 48,616.

To all whom it may concern:

Be it known that I, MARTIN J .KELLY, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Sprmg- Cocks, of which the following is aspeoification.

My invention relates to improvements in spring-cocks, and the object of my improvement is simplicity and economy in construction and convenience and efiiciency in use.

' In the accompanying drawing 1 Figure 1 is a side elevation of my. improved spring-cock.

Fig. 2 is a front elevation ofthe same.

Fig. 3 is a sectional view, on an enlarged Fig. 4 is asimilar view of the same-with the parts moved to a different posit on. i I

Fig. 5 is a side elevation, and in part broken away, of part of the body and connected parts, and on a still furtherv enlarged scale;

Fig. 6 is a sectional view on theline y-y of Fig. 7.

Fig. "7 is a plan view of the spindle memfication shown in Fig. 8.

Fig. 10 is a front elevation of the valve seat member shown in Fig. 9.

Fig. 11 is a plan view of the same.

Fig. 12 is a sectional view of a lavatory cock having the operating parts made according to my invention, and on the same scale as Fig. 8.

Fig. 13 is a similar-view of a faucet embodying my invention.

My improved spring-cock comprises "a body 10 having on one side an inlet 11 and on the other side an outlet 12, and on the upper end a seat inclosing an opening provided with an interior screw thread 13 which is closed by a cap 14, through which projects a spindle 15. 1

The body 10 is divided by a division wall 16 into two chambers, respectively areceiving chamber 17, on the lower side generallyand connected with the inlet 11, and a'discharge chamber 18 on the upper side, confor.

nected with the outlet 12, the said division I wall 16 having an opening 19 in line with the axisof the cap 14 and spindle 15, the lower side of the wall of which opening 19 serves as a valve seat 20.

' The cap 14 is an elongated structure and hasa bore of two diametersthe lower and larger portion 21- of which constitutes an extension'of the discharge chamber 18 and the upper portion-22of which is a fitfor the spindle 15 and serves as a bearing there 1 The lower and larger bore 21 serves'as a cam chamber for housing a pair of cotiperating end cams. .1,

One of the said end cams, serving as the upper end cam 23, isintegral with the cap 14, extending downwardly from the roof of the lateral or'overhanging portion of the larger'bore 21, relatively to the smaller or spindle bearing portion 22, the cam faces. being onthe lower side and, arranged in V-shape, the same being made duplex, so

that there is a V -shaped;cam face on each side of the axis. I

Opposed tothe upper end cam 23 is a lower end cam 24 that is integral with the spindle 15, the formof the cam faces there-. on being also V -shaped. WVhile in some cases the end Icammembers may have their opposed camface's incontactfor effecting the valve movements'desired' and to be described,I have in thepresent case provided special contact balls 26 that are supported- .by'thc lower cam 24 and spindle 15 and which make contact with thecam 'faces of the said upperend cam 23,'during the effecting of such movement. The said balls 26"are four in number, and

are located in pockets or wells 27, there being'onesuch' pocket and ball at about the middle of each' of the inclined surfaces 28 of the V-shaped cam faces in the said lower cam 24. r r The upper portion-29 of the spindle 15 is a fit in the spindle bearing 22in the cap 14, the middle portion isrelatively enlarged to form the lower end cam 24, and the lower portion 30 is in the form of an extension, below the lower end cam 24, and serves as a valve stem, extending through the valve opening 19 and below the valve seat 20.

Thelower end portion 31 of the valve stem 30 is screw threaded and has mounted thereon, and secured in-place by a nut .32, a

valve 33, positioned below the valve seat 20, suitably to cooperate therewith.

A spring 38 has the upper end engaged with the valve 33- and thelower end engaged with a seat 3-1 provided in the lower,

end of the body 10 and the said spring tends to hold the valve engaged with its seat, and

also holds the opposed cam surfaces in enheld inplace by. a. lock nut 37 passes .up-

wardly through the seat 34 and serves asa stop, in engagement with the Valve stem 30, to iimit'the downward movement ofthe said stem'and the lower cam member 24: connected thereto.

In operation when the spindle 15 is turned from :the normalposition the cooperation of the scam faces serves toforce the valve 33 from its seat, in opposition to. the spring 38, and-whenzthe spindle is released the spring will :tendto restore the parts to the normal position.

The spindle 15 is provided adjacent the upper end with a groove 45 in thefside wall which engages with a key &6, as'shown in Fig; 4, to holdlthe said spindle'away from the normal position and thereby hold the valve open,= in the depressedposition. The key 46 is pivoted by means-of a pin 47 in a slot rs, suitably to beswung in a vertical plane into and away fromthe engaging po sition, the said slot 48 being provided-in a top cap 49that covcrsthe upper end portion-i0 of the cap 14. The said top cap 49 is secured to the upper end portion 40 by means of a screw thread tl.

In some cases. an outlet 52 is provided .in the'cap 14- and provision is made for connecting the samewith the discharge chamber 18 and disconnecting the same therefrom by a set of grooves, comprising" a lower groove 53 across the lower cam memberfl l: and alongitudinal groove 54 connecting therewith on the periphery of the; spindle 15 and a lateral or: branch groove-55 connectingthe upperend of the groove 53vwith the dischargeopening -52.

The small outlet 52 and the connecting grooves areprovided in special cases to serve asaventg connection or outlet for the dischargechamber 18 and the portion'of the iipinggsystem connected thereto through the discharge opening 3 12.

It willbe noted as-shown and described that when the va'lveis' in the closed positionptl're'pressure offthe Water tends to hold theiavalve in such. closed position and the opening. is. effected, by I moving, the valve against.usuchmnressure:,

In themodification shown in Figs. 8 and 9 the bottom of the body 10 is closed or integral with the general body structure, and theseat 3 L" forth-e spring 38 is provided on the upper side thereof, and the stop 36 for the end of the stem 31 and the spindle member 15 is in the form of an integral'knob or protuberance on the said-up per side of the bottom 35 As the valve 33 is larger than the seat 20 as in the other construction described I provide the said valve seat20 on the lower side ofiaremovable structure in the form of the removable valvescatmember 56 which is secured in place .in the "body 10 by means of a screw thread57 provided in a'suitable opening in :the division wall 16 The valve seat member 56 comprises an annula-ribody-portion; the exterior of which isprovided;with.the said th-read'57, and at the upper :end there. is an annular, laterally eXtendingo-r overlapping flangeq58 suitable for engaging with a seat 59 onlthe division wall 16, either directly'or preferably-with a packing washer 6O interposed therebetween. The upper side of the'flange, or head. 58is provided with cross-slots 61 in diametral alinement and forming (essen tially a screwdriver slotfor receiving a screw-driver device for squaring the valve seat member 56 in place.

Such screw-'clriver device I provide in the forinof a diametral rib 62 on the spindle 15 at lower side of the lower cam member 24.

In the; assembly thevalve seat member 56 is mounted loosely on the lower portion of the-spindle member 15 between the integral lower cam member 2 and the valve 33 The spring 38 is placed on its seat 34 and tnenwthespindle member 1f with the valve seat member 56 mounted thereon as described is inserted in the body10,,an'd the valve seat member 56 screwed into-place. The lower end 63 of the valve-seat member 56 is tapered suitably to facilitateengagement of the threaded portion 57.

After the spindlemember 15 and-valve seat @member 56 are in place the cap 14-? is placed in position.

The-construction of the faucet style of cock shown in Fig. 13 corresponds to that shown in Fig. 9, difi'eringtherefromin dimensions the same having a removable valve seat member 56 cooperating withthe valve 33*, mountedgon the spindle 15".

In thelavatory cock shown in. Fig. 12 the inlet 11? to the body 10 is at the lower; end thereof. and except for the feature and changes that are involved with :the same, the internal structure corresponds :to' that'of the faucet vstyle shown in Fig. 13.

The inlet 11 is positionedat the lower side of thexbase 35' ofthe body proper 10, which base is provided with a laterally ex tending supportingjfiange' 63, and the: said inlet 11 is bridged by a spider 64 supporting the stop 36 that cooperates with the lower end of the spindle 15 to limit the downward movement thereof.

Below the inlet 11 and base 35 is a downward, sleeve-like extension 67 threaded at the exterior to receive a clamping nut 66, and also to receive at the lower end the screw threaded nut member 68 of a union 69. lower end in the form of a sleeve member which constitutes the inlet proper.

In the various styles disclosed the valve is opened against the pressure of the water, and when closed the said pressure of the water tends to hold the valve in the closed position. I

Also the valve is spring closed, the handle and end cam features being brought into play merely for effecting the opening of the valve.
