JOHN REPETTO, OF PHILADELPHIA, PENNSYLVANIA.
FLUID-COCK.
To all whom it may concern:
Be it known that I, J oHN Rnrnrro, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in F luid- Cocks, of which the following is a specification.
This invention relates to valves, and particu'larly to that class which is employed to regulate the flow of illuminating and heating gas.
The object of the invention is to provide an improved and extremely simple means whereby the accidental turning-on of the valve is eliminated by providing a gravityactuated latch mechanism attached to the valve-operating member.
Another object of the invention is to provide, in addition to the foregoing, and particularly in conjunction with those valves employed to regulate the flow of gas for heating and cooking purposes, means for indicating the extent to which the valve is open without necessitating the usual opening of an oven door in a gas-range, or the usual stooping over in order to determine this fact in viewing the height of the flame beneath a vessel over a flame.
A still further object of the invention comprises pivotally mounting upon the usual handle of a fluid valve, a latch provided with a weight, operative to normally maintain the former in the lowermost position permitted by a recessed guide, and to provide said latch with a manually actuated extension adjacent to one side of the usual valve handle.
These and other objects and details of the construction of the preferred embodiment of the invention are fully brought out, when read in conjunction with the accompanying drawings, in which Figure 1 is a side elevation of one embodiment of the invention as applied to a gas fixture used for illuminating purposes; Fig. 2 is a section on the line 2-2 of Fig. 1 in the direction of the arrow; Fig. 8 is a fragmentary top plan view of the valve portion of the device shown in Fig. 1; Fig. 4. is a development of the notched latch guide; Fig. 5 is an elevational view of the device as applied to a valve of a range, or the like, used for heating and cooking pur- Specification of Letters Patent.

poses; Fig. 6 is a top plan view of the same; and Fig. 7 is a development of the notched guide used in connection withthis form of the device.
Referring to Figs. 1 to 4, inclusive, of the drawings, a gas fixture is shown as comprising a section of a pipe 10, including a valve housing 11, and extending from the wall 12, while to the outer transversely bored end 13 of which pipe is pivota'lly secured a similarly bored member 14, through one end of which latter extends a tube 15, carrying upon its outer free end any common or well-known form of gas-jet 16.
NVithin the housing 11 is revolubly mounted the usual valve held in position by a screw 17 and manually operated by means of a thumb-lever 18. Extending through this lever, and pivotally connected thereto at 19, is a latch member 20, preferably provided at one end with a suitable weight 2]. and at its opposite end with a depending extension 22, adapted to be actuated by the fingers as they grip the lever 18 for the purpose of opening the valve and regulating the flow of gas therethrough.
Extending downwardly from the pipe 10, and concentrically with the housing 11, is a substantially semi-circular member 23, provided with a slot 24 extending horizontally through an arc of 180 degrees, and said slot at its opposite ends being provided with a downwardly extending oifset 25, into which the member 20 operates by gravity to force the latch, in order to maintain the same, together with the valve, with which it moves in exact unison, in either extreme closed position. Thus, it is obvious that with this construction, it would be difficult to accidentally open the gas-regulating valve with a consequent prevention of at least many of the accidental cases of asphyxiation.
Referring now to Figs. 5 to 7, inclusive, a main gas supply pipe is shown from which leads a nipple 31, connected at its opposite end to the common form of valve casing 32, through which is revolubly mounted a valve 33, provided with a handle 34 and through which extends an aperture 35 for a purpose hereinafter described. The side of the casing 32, opposite the nipple 31, is provided with an extension 36 leading lever 41 is adapted through the side wall 37 of oven, or the air-mixing chamber thereof, which latter in turn leads intoan oven, or into any well- 7 known 'form of gas-burner.
the extreme .open and closed positions of the valve The lever 41 is pivotally mounted at 42 upon the said valve and extends above and longitudinally along the said handle, wardly through the aperture 3'5 in the latter, and at its lowermost end portion is provided with finger-engaging enlargement 43.
In the operation in this form of the de-' vice, gravity acting upon the longer arm of the lever 41 and enlargement 43 tends to maintain the shorter arm of said lever in contact with the upper edge of the slot '39 in the member 38, said edge being provided, in-addition to the ofisets 40, with spaced saw-teeth offsets 44. Thus the engagementofsaid lever with one of the offsets insures the lnalntenance of the valve in either extreme open or closed position until released therefrom by upward pressure of a finger upon the enlargement 43. Also, as the handle 84: is oscillated to and fro, and
the shorter arm of the lever 41 passes suc-- cessively into the offsets 44, it is easy to deopening of the oven dooror stooping over termine the degree to which thevalve is open, or closed, without necessitating the to observe, in the case whereanjexposed gasburner isbeneath a vessel being heated, the condition of the flame.
Having thus described'my invention, what and thence preferably passes down-' I claim and desire to protect by Letters Patent of the United States is 1. A device of the character described comprising, a casing, a valve therein and having a stem, a stationary plate arranged near the casing and provided with a slot, said slot having its outer wall provided with notches, and a lever 'pivotally connected with the stem and having a portionthereoi' adapted for movement away from the casing to engage a selected notch in said outer wall.
- 2. A device of the" character described comprising, a casing, a valve therein and having a stem, a stationary plate arranged near the casing and provided with a slot,
said slot havlng' its outer wall provided with notches, a lever pivotally connected with the stem and having one end portion thereof arranged within the slot' and adapted to move awayfrom the casing to engage a selected notch in the said outer wall, and a weight secured to the opposite end portion'of the lever.- I V 7 3. A device of the character described comprising, a casing, a valve therein having a stem, a crank secured; to the stem and provided near its free end with a transverse opening, a stationary plate arranged near the casing and having a slot, said slot being provided upon its outer wall with a plu- V rality of notches,,a leverp-ivotally connected between its ends with the stem and having one end thereof projecting into the slot, such 7 end being adapted for movement away from the easing into engagement with a selected notch in said outer wall, the" opposite end of the lever having a transverse portion extending through the transverse opening in said crank, and a welght secured to the free end of the transverse portion.
In testimony whereof I have affixed my signature.
