.7 KINDLING DEVICE.

To. all whom it myconcem:

Be it known that we, CHARLES WILHELM,

a citizen of the United States, residin sing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Kindling Devices, of which the following is a 4 specification.

" Our invention relates to improvements in kindling devices and the objects of ournnprovement are simplicity and economy in construction and COHVGXHGHCB and eihciency inause.

- i In the accompanying drawing: Figure ri a plan view of our improved kindling device and a grat" f a r ve in relative position. for

use. ,Fig. 2 is a sectional view .on the line .a: m of Fig. 1, and the hearth of a stove, the ;:;latter being shown in broken lines and the 5 and 6 are sectional views onthe line y 3 i I comprising a central row, and a row each in kindling device being shown in side eleva tic-n. Fig. 3 is a similar view of the kindling device alone. Fig. 4' isa plan view of a partof the same on an enlarged scale. Figs.

of Fig. 1, of the body member and the spring member respectively. Fig. 7 1s a bottom view'of a part of the burner. Fig. 8

, is a view similar to Fig. 1 of a part of a modification of, our kindling device and a grate.

.A is our kindling device and comprises a burner B and supporting means comprising a spring device C. The burner B comprises a T-shaped body having at one end the cross-arm 10 which constitutes the burner proper and the inlet arm 11 that extends laterally or rearwardly therefrom at about right angles to the same. The said "burner proper 10 and inlet arm'll are pref- 12' at the, inner end of the inlet arm .11 to thejets 13 that are provided on the burner proper 10,. The said inlet 12 of'the inlet arm-11 comprises a head 14 having radial .airdnlet holes 15 and a front wall that is pierced by 'ahole 16 suitable for'receiving and supporting the inlet jet'tube D. As

" 1 shown the 'hole 16 provides a screw threaded engagement with the jet tube D. The said 7 jcttube D comprises a pieceof wrought iron specification or Letters latent. p t t l u 12, 1 application-medJanuar 10.1912. Serial No. 670,469!

. tubing havingthe rear end'17 reduced and brought to a taper,; has the body portion 18 threaded to fit the threaded hole 16 and has the front end 19 tapered or provided with any means desired for connecting with a supply of gas or fuel, as a. rubber tubing E.

The length of the rear end or jet portion 17 of the jet tube D or the amount thefsame projects into the head 14, and the relation of the same to the air inlet holes 15 are such as are determined by the proper conditions for the combustion of the fuel.

The burner proper 10 comprises as de-,

scribed a hollow arm and is of suitable length for extending along the lower side of the grate F in the hearth 21 of a stove G, is provided on the. upper side with guiding means, such as pins 22 or the equivalent, su table for guidlng and positioning .the

burner 10 relatively to the grate F, andalso has on the upper! side a plurality of burner 'jet tubes or jets .13 projecting upwardly therefrom suitably for entering the spaces 24 between the liars 15 of the grate F. which jets have suitable outlet holes for feeding the fuel to the flame.

, We prefer to have three rows of jets 13,

front -and in back of the said central row. the individual jets 13 of the three rows being arranged in line in cross-rows, and hav ing the spaces 26 between the cross-rows such that the jets 13 will. register withfithe spaces 24; between the grate bars 15 as mentioned, with the body of the burner 10 being held in abutment with the lower side of the grate bars 25-, As means for holding -the burner lO-against the lower side of the grate bars'as mentioned we provide a spring device O, engaged with the lower side of the,

placed in operati0n,'by means of one hand.

We prefer -to provide the springdevice, G with a tubular body 28,'-the'upper, enjdfQ!)v of which is; exteriorly threaded to and burner 10 and itself resting on the bottom engage with a threaded'hole aildoyflfi wardl'y projectingboss 31 on the middle of the-body ortionof the burner B, at the junction o the cross-arm or burner proper 'and the inlet arm or mixing chamber 11. '5 Thetlower end 32 of the body 28 is threaded eitteriorlysimilarly to the upper end suitably to receive 'anannular cap The body "28 has ag lon 'tudina-l bore the upper portion 34 of whicv is smaller in diameter 19 than. the lower portion 35, the two meeting about the middle of the length of the body 28 where a shoulder 36 is formed at the "upper end of the lower bore 35. The upper portion of the body 28 may be provided with radial vent holes 37 through the lateral wall. The body 28 when screwed to the burner B constitutes essentiallya fixed portion thereof. Areciprocating member 38 is operatively connected to the body 28, and base limited so reciprocal motion relatively thereto, is normally held in the open or extended position by means of a spring 39, and comprises a cylindrical body portion 40 that passestirough the hole 41 in the annular cap 33 through the lower bore 35, and extends into the upper bore 34, and is a sliding fit for the said upper bore 34: and hole 41, and guided thereby inits motion relatively to the body portion 28. A washer 42 and the to spring 39 surround the said body portion and are housed in the said lower bore 35, the upper end of the spring 39 bearing against the said washer 42 and holding the same in engagement with the shoulder 36 85 and the lower" end bearing against a dia metral pin 43- that enetrates the body portion 40 is normally held in engagement with the annular cap 33 by the spring. The lower end of the reciprocating mem- 40 her 38 being in the form of a rod is suitable for being entered into the hearth in the midst of accumulations of ashes so as to have the extreme lower end engage with the 1 bottom-of the hearth, notwithstanding such 45 accumulation, and the said extreme lower end may be provided with a head 44 for a' finish and which may be suitably rounded so as to permit of being forced to the bottom of the hearth in the manner described. The distance from the base of the "hearth to the bottom of the grate is lessthan the combined overall dimension of the normal overall len" th of the spring device C and the depth of t e burner body wherefore when a;

the device A is in position for use the spring 39 iscompressed and the burner B is held q resiliently engaged with the bottom of the grate. The length of the jets 1 3 is suchthat w th the body of the burner--10 in abutment w th the grate F the upper ends of the jets will beapproximately on the level with the top sides of the grate bars 25 or preferabl as shown, slightly below the same. "Accord and'pith the fuel burningat the jets 13 the ingly,with a supply of coal on -the grate" F said jets will be positioned so that the hefiit of the flame will impin e directly on the coal, and with thusual rafts in operation, will serve to kindle the coal quickly and economically, avoiding losses through wasteful heating of the grate bars. Furthermore,

although the burner is in close relation to the coal to be kindled; owing to the effects of the draft in drawing a supply of cold air over the burner the same will be maintained relatively cool and the burner will have long life and be practically indestructible.

()ur kindling device A is readily placed in position for use by bringing the lower end of the spring device G in contact with the base of the hearth and forcing the burner B downward suiliciently to permit the'guide pins 22 and jets 13 to clear the bars 25 and enter the spaces 24 when upon releasingthe same the spring device 0 will force the 55 burner 10 and the jets 13 upward into operative positions. The pins 22 may be dispensed with in some cases as shown in Fig. 8 and the jets 13 relied uponfor' positioning. The fact that the jets 13 are'tapered as shown, facilitates entering the same in. the spaces 24: in a proper manner for use.

-It is apparent that some changes from the specific construction herein disclosed may be made and therefore we do not wish to be understood as limiting ourselves to the precise form of construction shown and described, but desire the liberty to make such changes, in working our invention, as may fairly come within the spirit and scope of 10( the same. i

We claim as our invention 1. In a kindlin -device suitable for use under a grate an having a body portion, means for holding the said body portion in 10: abutment with the bottom portion of the grate comptising a. spring device havmg a relatively qfixed port-ion secured to the said body'pordiomand a member having a reciprocal 'motlpn ire latively to'the said body 11 portion. 5 i 2.
