"\ l Application filed July 27,1903- Serial No. 167,072,- lNo model To @ZZ-whom if may concern.-

in New York, ot A\ew Yorlnhavc invented certain n ew and useful Improvements 1n Igiting Attachments for Burners, of which thet'ollowing is a speci- `ticat1on. i

lt is well known that when a current of combustible gas impinges against platinum sponge the sponge is brought-'to incandescence and thcgas ignited thereby. It has been proposed to arrange such platinum sponge in the cen'- tral part of theincandescent mantle; but it.

has been found that with such an arrangement some time elapses b etore ignition takes place and that a consitlerablequantity of g-asA gathers in e' upper `vand loweivparts of the mantleswhich'when thesponge is brought to incandescence explodes, whereby the attendant concussion accompanying theV ignition'ot' the gas causes an al'ipreciableA decrease in the life of the incandescent mantle and so aggravates the main objection# frequent renewal of the same.

This invention relates to ments for burners, and more particularly to igniting-caps which may be easily applied to any burner-tube, and when once applied .it is only necessary Ito turn the cock of the burner and so permita current of gas to impinge against aplatinum sponge suitably attached to said cap and' in this manner ignite the rgas as Soon as it leaves" the burner, without the objectionable explosion accompanying ignition by matches, portable ignition devices, &c.

The object of" this invention is to obviate the objections above referred to by providing a device `which is easy to manufacture, simple to apply, and commendable for general adaptation.

For this purpose the invention consists of an igniting-cap for incandescent gas-burners by a. current of combustible gas, as will be igniting attach'- i out in the claims.

In the accompan \"1ng drawings, F1gure1l i fullvdescribed hereinafter. and finally pointed Be itv known that I.

'Similar letters of reference indicate corrcl sponding parts.

Referring to the drawings, A` represents a gas-burner provided with theusual .air-openings- (tand with a chimney provided with :ur-openings 7;' at its lower part. The burner is also provided with a rod/, which is verticallyadjustable by means of a screw d', which supports a'n incandescent mantle m. On the upper tubular part of the burner a is applied `an igniting-cap R, which supports a platinum sponge I in the path of the combustible gascurrent passing through the burner f. The burner-tube f is provided at its upper part with the usual screen s. The platinum sponge I is incandesced when brought in Contact with the combustible gas, which incandescence ignites the combustible gas, and so'lights the lamp without any portable ignition means, as matches, tapers, &c.

\ The igniting-cap R consists of a cylindrical part or sleeve n, made of suitable material, preferably sheet metal, the lower part of which is provided with a part n-, of somewhatlarger dimension than the part n, so as to form a `shoulder n2, by means of which the sleeve n rests on the upper part of the tube f. The

upper part ot' the cylindrical sleeve n is provided with an annular part n3., in which is seated the top onsuspeiiding part of the cap.

.This top t is preferably made otmagnesium, clay, or other non-combustible material, and

consists, essentially, of several radial parts t', `forming segmental openings .0 between the same and terminating in the central part t2, which 1s provided with atransverse pin 77, to

. which a platinum'wire 7,', with'a platinum sponge 1 suspended thereby, vis attached. The top t is also provided with a central opening t3, in which the mantle-supporting rod d can be placed when central support of thesame is preferred. y

Very often' attachable caps provided w'ith screens are sold with the incandescent gas'- mantles and are not arranged in the burners,

asishown in Fig. 2. 1n applying my'irnproved igniting means tosaid burners it becomes necessary to arrange .the screen .s 1n the. ignitingcap R, as shown in Fig. 4, for which purpose l f the sleeve n is provided with'an annular part a, in which the sleeve may rest. The cap R, consisting of the'sleeve w and the' topt, may

' be formed in one piece-#in fact, it maybe any means attachable to the burner-tube andmay be made of any suitable material or shape con `forming to an efiicient operation, the main feature of the invention being in. providinga portable attachment for burners easily manufactured and complete in andforv itself lby means of which the gas may be ignited.

My improved ignitingcap may be easily nianufactured and brought into the market in the form shown in Fig@4 and maybe purchased ata small cost and applied by any one to--the burners already in use or may be sold either as a separate cap orwith thev burners as a part integral therewith. y

The great disadyantage of gas-burners l which has caused many to adopt the electric llight'--namely, the use ofl matches-is overcome'by my improved igniting-cap, as it is only necessary by the use thereofl to turn the cock of the burner.V Matches are not only very often a source of inconvenience, but are also objectionable'on account of the danger of fire attendant the use of thesame. Furthermore, when the gas-Jet of the improved igniting-cap is accidentally' left open the gas emanating l Witnesses:

from the burner will immediately ignite, whereby the flame produced will give knowl- Theignition of the gas will edge of the' fact.

have the further advantage that -the gas Will be ignited and burned while emanating from the burner, and so remove the dangerof gas asphyxiation. When appliedto4 gas-burners .provided with incandescent inantles, the absence of explosions, lwith `attendant concussions, insures a longer life'to' the same, no

matches are required for its ignition, and all in= Jury caused by falling matches' is obviated.

The igniting-cap being complete in and for 4itself forms an article of manufacture which 60 -may be produced 1n large quanftlties, so reducing the cost of each cap correspondingly.

The improved igniti'ng-cap may beapplied vto.any burner by any one without requiring any changes inthe same, and may be.. due to its simplicity, 'manufactured at a low cost, giving tlius ample reason for general adoption. lclaim as new and desire to secureby Letters Patent- 1.
