Application filed February 21, 1913. Serial No. 749,836.
T all whom it may concern Be it known that 1, JOHN lVrNnnnn, a
citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have inventeda new and use- I ful Safety-Cock, of which the following'is a specification.
.Itis well known that from gas fixtures of i the ordinary construction, many fatal accidents have occurred from. persons carelessly turning on the gas as they remove their fingers from the key, thereby giving the plug a slight reverse movement suliicient to permit the gas to escape.
My present invention relates to a novel construction of a safety gas cock, wherein the liability of accidents of this character is obviated, and wherein I provide a locking device which will automatically and positively lock the plug when the latter is turned the open, closed or intermediate positions and will prevent-the accidental turning of the plug again as the hand is removed from the key, provision being also made forenabling the plug to be at all times tightly engaged with its body in either of its closed, open or intermediate positions, without the possibility of leakage of the gas, the locking of the plug preventing improper or accidental turning of the same.
My invention further consists of a novel devices adapted to coact with the operating mechanism of the cock, so as to insure the automatic locking of the same in the desired p0 sition, without requiring attention on the till part of the operator. v
To the above ends my invention consists of a novel construction of a safety cock, adapted for use with all fluids, the important features of which will be hereinalter described and :tully pointed out in the claim.
For the purpose of illustrating my inven tion, I have shown in the accompanying drawin s one form thereof which is at present pre erred by me, found in practice to give satisfactory and reliable results, although it is. to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise are rangement and organization of these instrunientahtiles as herein shown and described.
' tongues 19,
since the same has been- Figure l represents a side elevation oi a safety cock embodying my invention. Fig. 2 represents a vertical sectional view oi" Fig. 1. Fig. 3 represents a bottom plan view of Fig. 2. Fig. 4 represents a perspective view of the body of the cock, showing the handle or operating mechanism and its adjuncts removed therefrom.
Similar numerals of reference indicate corresponding parts in the figures.
Referring to the drawings :1 designates the body of ,the cock having the openings 2 and 3 therein, which are controlled by the plug 4, having the port 5 therein. The plug l tapers slightly upwardly to conform to the contiguous taper of the cock body and is provided with the stem 6 which is surrounded with the coil or other spring 7, whose lower portion rests upon the inturned flange or shoulder 8 of the casing or sleeve 9, which surrounds said spring, the outer portion of the latter being retainedin position by the washer 10 through which passes the threaded screw 11, the latter being seated in the threaded opening 12 of the stem 6.
13 designates a series of ratchet teeth in the upper edge coacting with the juxtaposed ratchet teeth 14 in the lower edge of the sleeve or casing 9, which latter has the handle 15 secured thereto in any suitable manner.
16 designates a spring or tension device having its center or intermediate portion 17 bent or deflected upwardly so as 0 contact with the lower portion of the plug l, said spring having the upwardly extending arms the inwardly deflected terminals or which engage contiguous recesses or .'seats 20 in the cock body, so that when the parts are assembled, as shown in Figs. 1, 2 and 4c, the contact oi the bent portibn 17 oil the spring with the bottom of the plug 4 will cause, thesame to tightly engage the contiguous bore of the body 1, so that any leakage of gas will be prevented 18 and under all conditions, either during the turning at the plug or when the latter is locked in any cl its open}. closed or intermediate can be readily ropositions. The plug 4 positions, as
tateol into any of its desired open, closed or intermediate, slightly on" the handle 15, so as to temporarily disengage the ratchet teeth 13 and i l, and upon the turning of the casing or sleeve a and stem t3 and the plug at late the desired position and releasing the "handle 15, the
by lifting llll tlli
i 'll of the cock body 1, the latter h ll lltld lll It will be further apparent that since the plug 4 is conical in form and the body 1 has a similar seat therefor, there will always be a tight joint between these parts under all conditions, by reason of the action of the spring 16, and during the rotation of the plugl into'the desired position, the'plug will not be moved from its seat and consequently there will be no leakage of the gas during the rotation of the sleeve 9 or the plug and its adjuncts. The parts can be readily disconnected upon the removal of the screw 11 and the spring 16 whereupon the plug can be readily withdrawn for the purpose of inspection, cleaning or repairs.
Itwill now be apparent that I have devised a novel and useful construction of a safety cock which embodiesthe features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
I claim as new and desire to secure by Letters Patent, is:
In a device of the character stated, a. body formed with a tapering seat and with an annular series oftecth at the small end of said seat, and formed with diametrically opposite recesses in its exterior, a tapering plug 'rotatably seated in said seat and formed with a stem at its small end, a sleeve having a handle and surrounding said stern and formed with an annular series of teeth at one end registering and intermeshing with the teeth of the .body, a spring coiled around the stem and bearing against the sleeve with one end to force the teeth of said sleeve into engagement with those of the body, and a flat bulging spring bearingwith the bulge at its middle against the large end of said plug and having upwardly and 111- wardly bent ends engaging the recesses in said body.
