SPECIFICATION forming part of Letters lateut NO. 624,733, dated May 9, 1899. Application filed July 8, 1898. Serial No. 685,407. 5N0 model.)

To all whom it may concern.-

Be itknown that I, PETER BARNIKEL, a citizen of the United States, resid-ingin New York city, borough of Manhattan, in the State of New York, have invented certain new and useful Improvements in Extinguishing Attachments for Qas-B urners, of which the following is a specification.

This invention relates to an improved attachment for gas-burners by which the flame is automatically extinguished after a given time, so as to produce not only economy in the use of gas, but also an effective protection against accidental extinguishment or against accidents resulting from the blowing out of the flame by persons unaccustomed to the use of gas. For this reason the attachment is especially adapted for the use of hotels, boarding-houses, &c., and also for the sleepingapartments of servants, &c. ,in ordinary dwellings, as the attachment forms a guard device against poisoning by the escape of illuminating-gas.

The invention consists of an extinguishing attachment for gas-burners, which com prises a clock-train attached to the gas-bracket, an auxiliary cock in said bracket, a notched disk operated by the clock-train and adapted to be turned by a handle attached thereto,and mechanism between said notched disk and the auxiliary cock,whereby after the disk has been set the clock-train produces the closing of the auxiliary cock and the extinguishment of the flame.

The invention consists, further, of certain details of construction and combinations of parts,which will be fully described hereinafter and finally pointed out in the claim.

In the accompanying drawings, Figure 1 represents a gasbracket with my improved extinguishing attachment applied thereto and showingit in its normal position of rest. Fig. 2 is a plan View of Fig. 1; and Fig. 3 is a side elevation of the gas-bracket, showing the at tachment in position whilethe flame is burning and before the same is extinguished.

Similar letters of reference indicate correspondin g parts.

Referring to the drawings, A represents a gas-bracket of any approved construction, which is provided with an ordinary stop-cock a and with an auxiliary stop-cock A near the .assumes the position shown in Fig. 3.

burner B". To the gas-bracket is attached, in any suitable manner, a small clock-train O.

In the drawings the gas-bracket is provided with a ledge, thatis cast integral with its midspring is applied a disk D, which is provided at its circumference with a notch cl. A crank E is applied to the square end of the mainspring-arbor, so that the mainspring can be wound up to a certain extent by turning the disk in the direction indicated by the arrows in- Fig. 1. Vertically above the notched disk D is arranged a fulcrumed lever F, which is provided with a hook-shaped end f, that is adapted to engage the notch of the disk D, the opposite end of the lever F being connected by an intermediate pivot-link f with a crank-arm f that is attached to the outer end of the auxiliary stop-cock A, as shown clearlyin Figs. 1 and 3. A strong helical spring f is interposed between the longer end of the fulcrumed leverF and a perforated stud f on the casing of the clock-train, said spring being applied toa rod f that is guided in the perforated stud and pivoted to the lever F.

My improved extinguishing attachment for gas-burners is operated as follows: When the attachment is in its normal position of rest, as shown in Fig. 1, the auxiliary stop-cock A is closed and the fulcrumed lever Fres'ts by the projection at its end in'the notch of the disk". The main cook a is also closed. hen

it is desired to light the burner, themain cock a is first opened. The notched disk is then turned by means of its crank-handle D in the direction shown by the arrow in Fig. 1, so that the projection at the end of the lever F rides on the circumference of the disk and By the intermediate connecting mechanism. between, the lever F and the crank of the auxiliary stop-cock the latter is opened, so that the burner can be lighted. As soon as the crank-handle D is released the clock-train is operated by its mainspring, as the same has been wound up to a certain extent by turning the disk. According as the disk has been turned more or less the clock-train will run for a greater or shorter length of time until the notch of the disk arrives again below the projection on the lever, so that the latter under tension of its spring f rengages the notch of the disk and produces thereby the closing of the auxiliary stop-cock and the extinguishment of the flame. When a light is required only for a short time-say only for a few minutes sufficient to get something from .the clock-train and the flame extinguished,

it is not necessary to shut off the gas from the-cock. When a greater length of time is desired) the notched disk is turned by its crank up to a poin near the notch, when the flame will burn, say, for about ten minutes,

' is closed and the flame extinguished,

7 On this exteriorvcasing is arranged a stop-pin suflicient to undress and retire, as in a hotel or servants room in a private house. When the clock-train has run outthat is to say, whemthe projection ,of the lever drops into ,t'henotch of the disk-the auxiliary stop-cock Should a longer time be desired by the person using the light, all that is necessary is to again tu rn the disk by the crank, when the gradual failing of the light calls attention to the fact that the clock-train is nearly run out. The light may thus be continued for another ten minutes. When it is desired to extinguish the flame before the clock-train has run out, the main cock a is closed and thereby the light directly extinguished. r

The Whole mechanism is preferably inclosed in'a suitable casing having a glass cover opening on that sidein which the crank is located.

9, agaiustwhich the crank abuts, so as to make the projection f of the-lever move up close to the notch, but prevent it from ping into it.

In some cases it may be desirableto interrupt the operation of the attachment, especially when the light is to be used for a greater length of time. In this case the crank can either be locked to the stoppin by a suitable link or other device, or any other mechanism for arresting the return motion with the clocktrain can be used. In this case the attach ment cannot work until the locking device is released again, when the clock-train will run its course and close the auxiliary stop-cock in the manner described and extinguish the light. Unless so locked, however, the-attachment will always accomplish its purpose-namely, the economizing of gas and the obviating of accidents resulting from blowing out the gas.

Having thus described my invention, I

claim asnew and desire to secure by Letters Patent- The combination, with a gas-bracket, of an auxiliary stop-cock, a clock-train supported on said bracket, a notched disk on the arbor of the mainspring, a crank-handle on said disk, afulcru med and spring-actuated lever provided with a projection at one end adapted to engage the notch of the disk, and intermediate conne'ction'be'tween thelever and the 'auxiliary stop -ceck. whereby the latter is opened by Winding or partly winding the m ain spring or automatically closed by the running down of the clock-train, substantially as set forth.

In testimony that I claim the foregoing as my invention I'have signed my name in presence of two subscribing witnesses.
