COOK OR FAUCET;

SPECIFICATION forming part of Letters Patent No. 769,491, dated September 6, 1904. Application filed May 19, 1904. Serial No. 208,688. No modelll To (LU lull-01m it Hwy con-corn.-

Be it known that 1, MICHAEL J RYAN, a citizen of .the United States of America, and a resident of Haydenville, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Cocks or Faucets, of which the following is a full, clear, and exact description.

This invention relates to faucets or other species of valves in which the valve and the stem thereof are arranged for movement relatively to the valve-seat and adjacent waterway in a line substantially right-angular to the axis of the operating-shaft or rotatable member which enters the valve-body vertically at the top thereof and has an operating bar or handle, connections between the handle-shaft and the valve-stem and guides for the valve-stem being provided, whereby rotational movement of the handle-shaft will cause a suitably-constrained substantially longitudinal movement of the valve-stem and valve.

The object of this invention is to provide in the valve of the type mentioned construetions whereby the movements of the valvestem and valve for opening and closing are positive, easy and certain, cheap and simple of construction, and durable for long and protracted use.

A faucet constructed in accordance with this invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical central longitudinal section through the faucet. Fig. 2 is a horizontal longitudinal sectional view substantially on line 2 2, Fig. 1. Fig. 3 is a side view of the valve and its stem. Fig. 4 is a cross-section on line at 4, Fig. 1. Fig. 5 is a View similar to Fig. 1, but showing a moditied construction. Fig. 6 is a cross-section on line 6 6, Fig. 5.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the body of the faucet, having therein the usual central chamber forwardly continued in the outletnozzle and rearwardly continued in the horizontal cylindrical waterway B, at the rear end of which is the valve-seat (I for the valve C, which is located within the chamber between said waterway and the inlet or coupling end of the faucet, the stem D of the valve being arranged horizontally and longitudinally of the body and right-angular to the operating-shaft G, which is titted through a gland in a common manner at the top of the faucet-body and has its lower extremity located within the central chamber in the fancetbody. The lower extremity of the handle-provided shaft (r is formed with the occentric & or other approved form of cam, and the forward end of the valve-stern is made of ring form, as represented at (.7, to encircle in the manner of an eccentric-strap the eccentrio ,7).

The valve-casing, as shown, between the coupling end having the inlet 10 and the central chamber 12 is constructed with an enlarged chamber 13, in which the valve C is located, and between the chamber 13 and the central chamber 12 of the faucet-body the aforementioned waterway B has connection.

The valve-stem, which is rigid and integral from end to end, has surrounding it at its middle portion, which extends through the somewhat contracted cylindrical waterway, the sleeve or cylindrical shell J, the outer surface thereof fitting comparatively closely and yet with capability for a free longitudinal sliding movement the cylindrical wall of the connecting waterwayB between the chambers 13 and 12, and a pivot-pin f, verticallyarranged, connects the sliding sleeve and the middle portion of the valve-stem, and this connection or jointing is such that when the operatingshaft G is turned and the eccentric revolved, moving the valve-stem longitudinally and also causing a swinging movement thereof in a horizontal plane, the oscillation which the valve-stem must have is one on the vertical axis of the pivot f and within the open-ended cylindrical shell or sleeve, which accommodates itself to the endwisc motions of the valve-stem by moving therewith back and forth in a straight line, having guidance along and support by the cylindrical wall surrounding the waterway B. The valve-stem is thus maintained properly central at all times, can have no transverse vibratory or ratthngmovement, and Wlll be drawn firmly and surely to its seat when the eccentric is thrown to its advanced valve-closing position.

In the arrangement shown in Fig. 5 the valve-stem is formed of two sections m and 02 one in endwise continuation of the other and pivotally jointed at O, the forwardly-extended section 791 having the eccentric encircling ring (Z. The other section, a, carrying the valve, has at its portion forward of the valve and which is located within the cylindrical waterway three or more (in the present instance four) radial wings a, the outeredges of which closely fit and serve as guides along and against the cylindrical surface of the wall of the waterway B, so that notwithstanding the lateral swinging motion which the valvestem section m must have, as imparted by the motion of the eccentric b, the valve-carrying section n has a true rectilinear opening and closing axial movement.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a faucetof the type indicated, the combination with the valve-body having a chamber therein, and a reaiwardly-located cylindrical waterway leading to said chamber and having a valve-seat opening at its rear end,

of the operating-shaft having the lower extremity thereof located in the faucet-chamber and provided with a cam, the valve-stem having at its forward extremity, an engagement with the cam and extending rearwardly through the cylindrical waterway and provided back of the valve-seat with the valve, and a cylindrical shell or sleeve open from end to end having a sliding fit in the cylindrical waterway and having a pivotal connection with an intermediate part of the valvestem whereby the necessary oscillation of the valve-stem as imparted by the cam-provided operating-shaft is constrained, and the valve maintained against displacement by such pivotal connection.
