FAUCET.

Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed April 29, 1919.. Serial No. 293,481.

useful Improvement in Faucets, of which the following is a specification.

This invention relates to cocks or faucets, and the ob ect of the lnventlon 1s to provide improved means for holding the valve disk in operative relation to the hand operated plug of the faucet.

Faucets have long loeen employed, and have been constructed with valve disks, usually of leather or composition material, which have floeen held to the movable plug.

of the faucet by means of a screw passed through the disk and threaded into the plug. Because of the fact that this screw is constantly subjected to the action of the liquid, the flow of which the faucet controls, said screw unvariably becomes corroded so that it not infrequently breaks when its removal is attempted. In all events, the head of the screw so badly deteriorates under the corrosive action referred to, that its removal by a screw-driver, as intended, is generally impossible, and gas pliers or wrenches are usually resorted to.

The object of the present invention is to provide means for holding the disk in position, independently of screw threads, and through a simple push connection, whereby the disk is frictionally held in place, and corrosive action will not render its removal arduous or difficult.

In the preferred embodiment of the invention the disk is provided with a cup or thimble adapted to be manually forced into a pocket in the plug, and maintained in such position by friction, as well as the fact that any attempt by the thimble to leave the pocket will produce a partial vacuum which will serve to hold the thimble against removal.

Features of the invention other than those specified will be apparent from the hereinafter detailed description taken in conjunction with the accompanying drawings.

In the accompanying drawings I have illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative only, and not as defining the limits of the invention.

Figure 1 is a section of a faucet showing thea present invention as applied thereto; an

Fig. 2 illustrates the present invention removed from the faucet.

Referring to the drawings A indicates a faucet provided with the usual screw plug B adapted to be operated by a handle C, associated with the stem 6 of the plug, for the purpose of raising and lowering the plug for seating or unseating the valve, as desired". The faucet is further provided with the usual feed duct D and the outlet duct E between which is a valve passage F peripherally of which is formed a valve seat 7 I designates a thimble open at its top and closed at its bottom except for a central aperture through which a bolt H is adapted to Woo passed, the head of the bolt seats within the thimble and its shank extends downwardly and through the valve disk G. A washer g is slipped over the shank of the bolt below the disk and a nut H is screwed on to the bolt to bind the parts together. The hole in the disk, through which the bolt passes preferably fits the bolt rather tightly so that in installing the disk initially, it is screwed to the threads of the bolt and the washer G and nut H thereafter applied.

The thimble I may be made of any suitable material, but is preferably resilient so that it may be readily manually forced into a hole or pocket J drilled into the bottom of the plug B and adapted to receive said thimble for attaching the disk G to the plug. In attaching, the thimble is merely pressed into the pocket J so as to frictionally engage with the walls thereof after the manner shown in Fig. 1.

Through the mounting of the disk as described, it will appear that during the operations of the plug the disk is free for rotary movement relative thereto, and may thus remain stationary during rotation of the plug B. This is a decided advantage, since the disk G will not be forcibly ground against the valve seat and worn out through such operation as is now generally the case where the disk is rigidly screwed to the plug. When it is desired to replace the disk with a new one, it is only necessary to grasp the disk and withdraw the thimble I, the restraining power of said thimble being insufiicient to withstand such a manuallyapplied pull though entirely suflicient to normally hold the disk in position.

Having thus fully described the invention,

v Letters Patent is:

what I claim as new and desire to secure by l. A valve embodying a valve seat, a plug movable toward and away from the seat, which plug is provided in the;end thereof adjacent the seat with a pocket, a valve disk 7 positioned adjacent the pocketed end ofthe plug and adapted to cooperate with the valve seat and a thimble having rotatable' connection with the valve disk and resiliently and frictionally held within the pocket ofthe plug. for the purpose of mounting" the V lindrical thimble closed at its outer end and seated in said pocket, a valve disk posiv tioned between the plug and the seat, and a 'bolt passing through the closed end ofthe Copies of this patent may be obtained for thimble and through the valve disk for mounting the disk on the plug for longitudinal adjustment relative thereto and for movement therewith toward and away from the seat. 7 j 7 7 '3.

In testimony whereof, name tJ this specification.
