SAFETY. ATTACHMENT FOR RANGES.

Specification of Letters Patent.

Application filed .Tune 29. 1916. Serial No. 106,699.

To aZLwkom itmag concern:

Berit:kn'ownwthatl, FRANK J. EBLE, ,c1-ti-.

zen of the UnitedStates,residin-gat- New York cityyin the county of New-Yorkand State. of, New" York, have invented certain new and useful, Improvements: inSafety At;-

tachments :for; Ranges and 11 do declare the following'to "be a full, clear, and=exact description 'ofthe invention, such as i will enable; others skilledxin the: art to whlch ltqapimprovements insafetyattachments for: gas

hi ghly efficient; for the:

ranges, andithe' primary object of the inven:

tion: is to provide. an attachment ofthis;

character that is adapted to. be-secured to the valves that control the burners atrthez top and bottomaof the oven, sothat only one burner may be-usedat atime thereby preventing any chan ce: of an explosion in the: oven.

Another object of the inventioniisyto provide adevice of this character -which is;in-- expensive to manufacture,. durable. and purposessfor; which it is intended.-

lVith these and other objects in view, my invention resides in; the; novel features of construction, combination and arrangement of parts to be hereinaftermoreparticularly pointed out in the specificationandclaim.

In the accompanying,drawingsz:%

Figure 1 is a perspective showing my attachmentapplied toa gas range;

Fig. 2 is a detail perspective'of the.l00k+ ing strip;

Fig. 3 is a detail perspective of one of the operating handles and the locking pin.

In describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which the numeral 1 designates a conventional type of gas range to which this attachment is ap' plied, having a vertical manifold main sup ply pipe 2 along one side, that has projectlng therefrom a pair of branch supply pipes 3, which lead to the burners at the top and bottom of the oven. The branch supply pipes 3 are provided with valves 4, which are of the conventional type used in stoves of this character.

The above recited elements are common to various types of gas ranges, employing an oven, although the arrangement and positioning may be slightly different in different stoves, the manifold and branch supply 1 in all types.

pipeswill be arranged inthe same relation My improved safety attachment: consists of a pa-1rof-horizontallydisposed parallel handles 5" which have their inner ends 6 bifu'rcated; and attached to the valves 4 inthe branch .snpply pipes. Alocking pin'l' is po-,

vsitioned through alining openingsin thebifurcated portions of the handles, and also all-Opening in the top of the valve, so that the handles will befoperatively connected withthe valves. This pin 7 is readily detachable, so that the handles may be attached to orremoved from the; valves by a very quick and simple; operation. The other ends of the handles 5 are received in slotsin-the.

ears 8, that arev attached to the side of the,

gas stove shown inthe accoinpanyingdrawr lngs, and'these handles are adapted to rotate freely w1th1n the ears.

Projectingfromthe sides of the handles 5 1 at; opposite; points are-laterally extending lugsu9 and 10, which are formed integral with thehandles, and are positionedinalinementiwith each other. These projectinglugs 9 are adapted when the valves areclosed to be disposed in, parallel relation, butwhen one; of the valves is open, thelugs are turned with the handle so that they will, be -pesi tioned; at right angles to the lugs of the ads jacent handle. Slidably mounted on ithe Side of the stove 1 between the parallel handles 5-is astrip 11, which has itswupper end bent laterally outwardly as shown at 12, while its lower end is inclined downwardly and outwardly as shown at 13 with its extremity bent horizontally as shown at 14. This strip 11 is mounted on the side of the stove 1 by projecting headed studs 15 that are positioned through elongated slots 16 in the strip.

In Fig. 1 of the drawings, I have shown my safety attachment applied to a gas stove,

with the lower valve that operates the bottom burner of the oven open, while the upper valve is closed and locked. By this arrangement, it will be obvious that to open the lower valve it is necessary to turn the lower handle 5 and that consequently the projecting lugs 9 engage successively the inclined portion 13 and extremity 14 of-the lower end of the strip 11, and force the same upwardly, until the end of the lug is positioned beneath the extremity of the strip as clearly shown in Fig. 1 of the drawings. When in this position, the out-turned end 12 at the upper end of the strip will be stationary beneath the lug 10 on the upper handle 5, so that it will be impossible to turn this handle to open the upper valve.

As soon as the lower valve is out OK, the projecting lugs on the lower handle will resume their normal position parallel with the lugs on the upper handle, and the strip 11 will be free to move upon the rotation of the upper handle as the projecting lugslO will force the strip downwardly and consequently will lock the lower valve.

This attachment affords an easy and efficient safety means, that may be readily attached to a gas range and whichwill prevent both burners in the oven from being operated at the same time. The danger of this is well. known and explosion often results from ranges that are not provided with some safety attachment to prevent the operation of both burners. This attachment may be easily applied to any type of gas range, it only being necessary to secure the ears 8 in whichthe handles are mounted thereto, and attach the bifurcated ends of the handles to the valves. The sliding locking strip between the handles may be easily secured thereto in the manner herein before described.

It will be noted that during the operation of the device, only the lugs 9 on the lower handle and 10 on the upper handle will be used, but the lugs on the opposite sides of these handles are placed there so that in case the handles should be placed on backward, this device'would operate regardless. When lugs are only used on one side of the handles, great care has to be taken to place the handles in correct position or the safety device will not operate. By placing the lugs on both sides of the handles, any person not skilled in the operation of this attachment may secure the same to the stove and it will be sure to operate.

From the foregoing description, the construction and operation of my improved safety attachment for gas ranges, the manner of placing the same to use and the operation thereof will be readily understood, and it Will be seen that I have provided a simple and efficient device for carrying out the objects of this invention.

I claim In combination with a gas stove, .a main supply pipe for the same, a pair of spaced branch pipes connected to said main pipe, valves in said branch pipes, parallel operating handles having bifurcated ends for engagement with said valves, ears projecting outwardly from said stove and secured thereto, said ears being provided with slots to receive said operating handles, integrally formed lugs projecting from both sides of said handles whereby to prevent the application of the handles in an inoperative position, said lugs disposed in parallel relation when the valves are closed, a locking strip slidably mounted on studs projecting from the side of said stove, said locking strip having outturned ends adapted to engage said lugs whereby to prevent the opening of both valves simultaneously.

In testimony whereof I have hereunto set my hand inthe presence of two subscribing witnesses.

FRANK JOHN EBLE.
