SELFCLOSlNG FAUCET.

PECIFCATON forming part of Letters Patent No. 340,329, dated April 20, 1886.

Application filed January 21, i886. Serial No. llhlll. (No model.)

To @ZZ zij/"tom it may concern:

Be it known that I, HENRY B. LEACH, of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvementsin Self-Closing Faucets, of which the following is a specification.

In the accompanying drawings, iu which similar letters of reference indicate like parts, Figure l is a vertical section of a faucet embodying myinvention. Fig-2 is an elevation of parts of the easing, diaphragm, valvestem, and one of the rollers, the cap having been removed. Fig. 3 is a vertical section taken on a line at right angles to the line of thc section in Fig. 1. Fig. 4. is a plan view with the cap removed. Fig. 5 is a plan view of the uuder side of the cap. Fig. 6 is a perspective View of one of the rollers. Fig. 7 is a view of the diaphragm provided with a slight modification. Fig. Sis a vertical section showing further modifications. Fig. 9 is an edge view of one of the rollers. Fig. 10 is a sectional detail view showing a change in the shape of the rollers.

Ais thebody or casing of the faucet, provided with the nozzle A and inlet-tube A.

B is the cap, held in position 011 the casing by the screw b and washer c, the latter encircling and the former screwing into the stem C, which passes up through said cap. The valve-stein C is provided with the valve D, packed at D', the packing D, and the spring E.

F is the handle integral with the cap B.

H is a diaphragm bored centrally to allow the passage of the stem C, screwed into the casing A, and provided with shoulders H', which rest on the upper edge of the casing within the cap.

I is au annular .stop for limiting the motion of the valve-stem. The upper surface of /the diaphragm l-I is provided with the double inclines h-that is to say, the circular path or track surrounding the valve-stem has four in clines, preferably straight, as shown in Fig. 2,

,.biit, if desired, concave, as shown in Fig. 7,

the two apexes h being opposite cach other, and the two lowest points, Il, being opposite each other. The under side of the cap, which is opposite and over the diaphragm, is provided with double inclines 7c, exactly similar tothe double i nelines 7l, so constructed and arranged that the apexes 7c are exactly opposite the apexes h, and the points of greatest depressiomt, are exactly opposite the lowest points, h.

L L are rollers placed freely between the two sets of inclines and within the shell of the cap B. rllhese rollers may be of any desired shape, provided of course that they are round. In Figs. 2, 3, 6, and 9 they are of convex disk shape, in Fig. 10 they are flat disks, while in Fig. 8 they are spherical or balls. \Vhen the handle F isturned and partial rotation imparted tothe cap, and hence to the inclines on the under side thereof, the rollers roll up the inclines h onthe diaphragm and the cap is lifted, thus raising the valvestem and allowing the water-'t0 pass through the faucet. The

pressure of the spring E draws down the valvestem when the handle is released, and closes the faucet in the ordinary-manner, the rollers rolling back from the apeXes of the inclines to thelowest points thereof.

It will be observed that the rollers L, whether of the -shape shown in Fig. 6, 8, or 10, are rollers in the strict sense of the term, and not wheels, as they travel on their peripheries, but do not rotate on theiraXes.

If desired, the path of the rollers grooved out, as at P, Figs. 8 and l0.

The eifect of the rollers placed between the reverse inclines is to reduce the friction when the valvestem is moved to a minimum, so that the moving parts are always operative without the aid of a lubricant.

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

1. In aself-closing faucet, the combination, with the reverse inclines or sets of inclines placed opposite each other, one of which inclines or sets of inclines is capable of partial rotation, of one or more intermediate free rollers, substantially as and for the purpose set forth.

2. The combination of the rotary cap B, provided on its underside with acurviliuear track, the stationary diaphragm H, supported by the body of the faucet, and provided on its upper may be surface with a curvilinear track, said tracks having their similarly-formed points of elevation and depression located opposite to each IOO other, the free rollers L, placed between the tracks, the valve-stem C, aud the spring "E, all arranged to operate substantial] y as shown and described.

3. The combination of the cap B, provided on its under side With one or more uclines, k, the diaphragm H, supported by the body of the faucet, aud provided on its upper surface with one or more inelines, h, and one or more free rollers, L, placed between the iuclines ou the cap and the iuclines on the diaphragm, substantially as and for the purpose set forth.

4. The combination 0f the cap B, provided on its under side with the double iuelines k,

the diaphragm H, supported by the body of r 5 the diaphragm, substantially as and for the 2o purpose Set forth.
