IMPROVEMENT IN lFAUCETS.

Spccilication forming part of Letters Patent Nol 23,310, dated March 252, 1859; Reissue No. 753, dated 1859; Reissue No. S01, dated August 23, 1859.

To all whom it muy concern:

Be it known that I, JAMEs POWELL, of Cincinnati, in the county of Hamilton and State of Ohio, have invented anew and useful Improvement in Faucets; and I hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

The said invention relates to that class of valve cocks in which anI eccentric on the op erating-stem is employed to move the valve to and from its seat.

In order to insure the accurate seating of the valve and avoid any abrasive action between it and its seat, it is of especial inportance in such faucets to preserve the valvestem from any lateral motion. For this purpose it has been common to construct the valve-stem with a yoke havingits bearingpoints connected by bands encirclingthe cam and a sufficient distance apart to permit the partial or entire rotation of the cam between them without causing deviation from a rectilinear path. This is disadvantageous in various respects, chiefly from the difliculty of inserting and removing a valve-stem having so great breadth of heath The object of my invention is to so construct and operate the valve-stem that it may be conned to a strictly rectilinear path, permit the complete rotation of the operatingcam, and at the same time be destitute of such protuberance upon its head as to necessitate undue enlargement ot' the water-way to permit the passage of the valve-stem through itin putting the faucet together or taking it apart.

In the accompanying drawings, Figure 1 is an axial section of a basin-cock embodying my improvements, the plane of section being parallel with the operating-stem, and some of the parts being shown in elevation. Fig. 2 is a perspective view of the operating-stem and the valve-stem detached.

A is the valve-chamber. C is the operatingstem, constructed with a circular cam, F, and collar G, and terminating in a pivot, c, which occupies a step or socket, E, in the wall of the faucet. The stem G is confined in position and leakage around it prevented by the means described in my patent of December 21,1858, a gum cushion, Q, being interposed between the collar G and a loose collar,R, whichlatter is fitted to the cap D by a ground joint.

The valve-stem H .has a attened'head, I,

which iiattened portion is slotted longitudinally, i, Vso as to receivethe pivot c ofthe stem C, which is thus made effective to prevent the displacement of the head1 in two directions, while it is held in'theother two directions by being conined, as shown, between the socket E and cam F.' The'r longitudinal motion necessary to open and close the valve is imparted to the valve-stem through the medium of two iianges, J and J', on its head I, engaging on each side with the cam F. KK -K are spurs 0r projections onthe valve-y stem H,which serve l to confine it to an accurately central position within the chamber A and guide the valve to its seat in the act of closing. 1

The valve L is of indiarubber, and is adjustable on its stem by means of a pair of screw nutsI or collars, -M M', which supply the place of the customary nut and fast' collar.

This valve-cock can'be made at a much less expense than those now in use, is less liable to derangement, and is easily repaired withou detaching from the supply-pipe.

The valve is operated with great facility, the cam having no stop pins or other restrictionto its sweep, nor any one arbitrary point it must assume in order to close or open the passage, the cock being effectually closed atany point of one-thirdof the rotation of the cam-stein and effectually opened at any point of the other two-thirds of its circuit. The peculiar arrangement of the operative parts dispenses with the necessity of spring, connecting-screws, or pins to hold the valve-stem in position. rEhe cam, being confined at its periphery only by the yoke which it touches at two opposite points, can be easily withdrawn for inspection, cleansing, or repair of the cock. It works with the least possible friction, 'and the form and dimensions of the yoke are such as permit it-s ready insertions and withdrawal through the water-wayfand involveno unsightly swelling of the chamber at this part.

The adjustable shoulders M M enable the valve to be set up as it wears, so as to dispense withthe necessity of' a new plug, and the parts' do not require to be made with the mechanical precision which is necessary when July/.5, Y,"

2 t f `olao1L one shoulder of the plugor valve is a xture.

1t kwill be evident that thisarran gement is equally applicable to valves closing either in the direction of the current or against it,'and in either case the closing oi' the valve is so gradual as to avoid injurious concussion and reaction.` .t

The spurs K will evidently operate'with equal'efiect, whether located above or below the valve, a slight elongation of the lowerend of the valve-stem' being needful in the latter case. Itis not absolutely essential that the said spurs should `be attached to the valven stem. Il' preferred, they may constitute or be lreplaced by a bridge through which the valvestem Aisadapted to slide. l

It will be evident that this invention is` 4'equally applicable to variousY other descrippath; but I know of no instance in which theseresults have been accomplished with a valve-stem adapted to Ybe inserted or withdrawn through the water-way without undue enlargement of the same and to permit the complete rotation of the operating-cam.

. I claim as new andof my invention and desirel to secure by Letters Patent- 1 1. Thevalvestem H, formed with projecting Han ges J and J when conned to a rectilinear path and operated by acam oreccentric which engages with it at two opposite points, in the manner and for the purpose set forth.

2. The described arrangement and combination of the slotted head I i, pivot c, socket E, and cam F, operating in the manner set forth to prevent lateral motion of the Valvestem.

In testimony of which invention I hereunto ,set my hand.

JAMES POWELL.
