MAX JAKOBSON, OF NEW YORK, N. Y.
SAFETY GAS-COCK.
SPECIFCATION forming part of Letters Patent N 0. 685,612, dated October 29, 1991.
Application filed March 12, 1901. Serial No. 50,798. (No model.)`
To all whom it may concer-71,:
Be it known that I, MAX JAKOBSON, a citizen of the United States, residing in New York, borough of Manhattan, in the State of New York, have invented certain new and useful Improvements in Safety Gas-Cocks, of whichthe following is a speciication.
My invention rela-tes to gas-cocks 'provided with safety attachments for preventing the accidental opening of the same, the object of the invention being to render the construction simple and economical as well as practical and durable, so that the parts will not readily get out of repair and so that the safety device cannot be accidentally operated, but has to be done intentionally; A To these ends my invention consists of a gas-fixture in which there is located in the plug-bearing or bearing-sleeve of the same a longitudinal bore or hole,in which is contained a spring-actuated locking-pin, the outer end of which is adapted to protrude into a notch or recess in the plug, in which recess is pivoted a small linger-lever, one end of which is inengagement with said pin and the other end of which projects downwardly alongside the key oroperating-handle, so as to be readily manipulated simultaneously with the turning of the cock, all as will be hereinafter 3o-described in detail and then claimed.
In the accompanying drawings, Figure 1 is a perspective view of a gas-burner with my improved safety-cock. Fig. 2 is a larger longitudinal section through the same in a plane taken also longitudinally through the gascock, and Fig. 3 is a transverse section on the line 3 3, Fig. 2.
Similar letters of reference indicate corresponding parts. l
Referring to the drawings, A indicates a suitable gas fixture or bracket provided with the usual burner B. Turning within the bearing Within the bearing-sleeved of the fixture or bracket A is the usual rotary plug C of the gas-cock, `which plug is provided with an operating key or -handle C and with a transverse passage C2, through which the gas may pass to the burner when the gas-cock is open. The plug C is provided at one side with a longitudinal recess or notch d, a por tion of which recess or notch is exposed, while 'the other portion is located out of sight in the bearing-sleeve ct. Within the recess d a small finger-lever D is pivoted at d', so that its upper end extends upwardly into the recess d' 55 Within the stock or mass of the gas fixture or bracket, while the other end protrudes downwardly alongside of and near the key or turning handle C', so as to enable the protruding end of the level` D to be depressed simultaneously with the grasping of the said keyhandle C and the turning of the plug so as to admit the gas to the burner. f
A longitudinal bore or hole e is formed in the one side of the bearing-sleeve of the gas fixture or bracket A, so that in the position shown in Fig. 2 the same will open into `the recess or notch d, permitting the locking-pin E therein to be projected, by means of a helical actuating-spring e', into the said notch or recess d and against the inner end of the operating-lever D, thereby moving the said end inwardly and the other protruding end of the lever outwardly. The described safety device when the gas-cock is closed holds the same in closed position against accidental turning of the plug and the consequent ad-v mission'of gas into the room. The lever D is so located and is of such size that it is not apt to be accidentally operated bya person in passing rubbing against the key or turning handle. By arranging the main parts of the device out of sight they are not likely to be nor can they be readily tampered with, so as toget the device out of order,
To operate the device, it is only necessary to take hold of the handle or key of the gas.- cock and with the thumb or one linger press at the same time (as indicated by dotted lines, showing a hand, inrFig. l) on the protruding end of the operating-lever, and thereby press the locking-pin E back into its guiding-hole e and out of locking engagement with the rotary plug C. When the gas-cock is closed, the locking-pin automatically engages in the 95 recess in the plug and at the same time throws the operating-lever into operative position.
It is evident that the invention can he applied in general to all devicesv by which the supply of gas or liquid is controlled by a turning plug.
What I claim as new is- The combination, with a gas fixture or IOO bracket, a rotary plug provided with a gaspassage, and turning Within said fixture or bracket, and means for turning said plug, saidixture or bracket having a longitudinal bore orhole at one side, open adjacent to the plug, and said plug having a longitudinal recess or notch adjacent to said bore or hole, of a spring-actuated locking-pin guided in said bore or hole, and adapted to engage in said notch or recess and a lever pivoted in said notch or recess and engaged at its inner end by said locking-pin, While its other end projects from the plug in a position for convenient manipulation, substantially as set forth.
In testimony that I claim the foregoing as inyinvention I have signed my name in presence of two subscribing witnesses.
MAX JAKOBSON.
