ALCOHOL LAMP.

Application 'inea March 151, 192e. sefiai no. Meer.

' 5 vices of this description' which may be utilized for various purposes, especially forincubators, brooders andthe like.v

lith these ends in view,- this invention consists in the details of constructiongand 10 combination lof elements hereinafter set forthv and then specifically designa-ted by the claim. In order that those skilled inthe art to which this invention apperta-ins, may understand how to make and use the same, I will describe' its construction in" detail, referring by numerals to the accompanying drawings forming a part of this application, in which Fig. 1, is a plan View of my improved alcohol lamp.

Fig. 2, is a side elevation of Fig. 1, partially broken away and sectioned to show the interior construction of the lamp and also illustrating a portion of an incubator as an example of an applicationof the device.

In carrying out my invention as here embodied, 10 represents a tank or alcohol supply reservoir having a collar 11 projecting upwardly therefrom, over which the tubular base 12 of the lamp is adapted to snugly fit to prevent the escape of liquid or fumes at this point.v 13 represents a tubular shank formed with the body of the lamp 14, this shank extending intov the base and being secured thereto, either by friction or in any other suitable manner. TheV body 14 is of considerably larger diameter than the shank 13, and has onefor more series of holes 15 formed around the upper portion thereof, and around this body is fitted the sleeve 16 adapted to loosely slide up and down upon the body so as to regulate or direct the How of vapor from the holes 15,V as hereinafter explained.

17 represents a bail, the ends of which are pivoted to the sleeve 16 by means of the studs 18, and this bail carries a stem 19, adapted to be attached to a lever 20 connected with the usual thermostat of an incubator 31 or the like.

21 represents a cap adapted to fit snugly over the upper end of the body 14, and this cap has projecting upward therefrom a prong 22; the cap and prong preferably bematerial.

ing of copper orvother high heat conducting 23" represents a pilot cup which is provided with a shank 24 adapted to fit up'on theV shank 13' of the body and be held in place by friction o'r otherwise, and this cup as illustrated in the drawing is intendedy to be positioned just below the lower portion of the body and spaced therefrom sufiic'iently to" perm'it the insertion within the cup ofa suitable absorbent'material 25.'v

26 representsa fibrous wick which extend thru the' shank 13y andbelow the samesufiiciently to' reach into and preferably to the bottom ofthe reservoir 10, the' upper end ofv the wick beingmore lorpless expanded so as to approxiniately vfill the lower'y portion of th-e body 14 in order thatalcoho'l may be drawn by capillary attraction from the-reservoir thru the shank 13 and .expanded to vaporization at the 'upper end of the wick.l

From the foregoing description the operation of my improved alcohol'lamp will be obviously as follows: The reservoir 10 is supplied with a suflicient quantity of alcohol by filling it thru a suitable inlet 27 and the wick will absorb and raise a supply of alcohol within the lower portion of the lamp, where it will be vaporized by the heat generated from the pilot cup 23 which has been previously saturated with alcohol or'other easily ignited material and lit.

The vapor thus generated within the body of the lamp will bel forced thru .the openings 15 andv ignited by the fiameissuing from the pilot cup so that thereafter these jets of flame will continue tov burn vafter the pilot light has been exhausted.

The jets of vflame issuing from the openings 1,5 will continue to heat the body, its cap and prong 22 and thus continue'to generate the vapor .for supporting said jets of flame; the prong being extended to absorb the heat ofthe jets of flame, and thus insure the proper temperature of the body to continue the generation of the proper amount of vapor.

When the device is applied to an incubator Vor the like, and the stem 19y connected with with the leverv 2() of the usual thermostat mounted in such apparatus, the lowering of f the temperature within the apparatus below the heating capacity of the lamp increases the response of the thermostat to this heat increase will cause the sleeve 16 to be lowered and thus permit the flame jets to project away from the body 14C and thereby again lower the temperature.

lVhile I have shown and described the sleeve 16 as being' operated by a thermostat, it is to be understood that an equivalent manually operable mechanism may be substituted tor said thermostat. It has been 'found in practice that a lamp made in accordance with my improvement may be so linely adjusted that the temperature Within the incubator or like apparatus will beso controlled asrto maintain a temperature almost tree from fluctuation, the variance beingonlyxa traction of a degree of Fahrenheit.-

One otthe advantageslof my improved lampfis that vitis lightei.' ot construction, easily assembled, and'is readily dismembered for cleaning or repairing. 1

Of course I do not Wish to be limited .to the exact detailsbf construction as herein shown as these may be varied Within the limits ot' the Vappended claim WithoutV departing from the spirit oit' my invention.

Having thus fully described my invention', what I claim as'neW and usetul is :Y
