Applation led September 13, 19l2. Serial No. 720,207.

T0 all whom it may concern Be 1t known that l, WYILLIAM R. THURS- -ToN, a citizen of the United States, residing be employed upon locomotive engines orv wherever a brilliant illumination is required.

The device herein disclosed employs acetylene as an illuminant, and means is provided for receiving and moistening the carbid.

The invention aims to provide means for heating the interior of the water tank, to prevent freezing of the contents thereof.

Another object of the invention is to provide a movable shield for directing heated air from the burner into the pipe which enters the water tank.

Another objectof the invention "s to improve generally and to increase tht utility of, devices of that type to which the present invention appertains.

With the above 'and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made Within the scope of what is claimed without departing from the spirit of the invention.

ln the drawings, Figure l shows the invention in front elevation, parts being broken away; Fig. 2 is a vertical longitudinal section through the water reservoir and attendant parts; Fig. 3 is a side elevation of the complete structure, parts being broken away; Fig. /l is a vertical longitudinal section of the carbid receptacle and of the Water reservoir, together with attendant parts; llig. 5 is a transverse vsection on the line 5 5 of llig. 2; Fig. G is a fragmental top plan; Fig. 7 is a side elevation of the shield, the View depicting portions of the mechanism whereby the shield is manipulated, parts being broken away; Fig. 8 is a top plan of the shield.

ln carrying out the invention there is provided a base l, fixed to and upstanding from which is a support 2, supporting a reflector 3 which preferably although not necessarily is rof the common parabolic type.

the base l carries a supporting structure which may take the form of a plurality of legs 4, connected with a funnel shaped gas chamber 5, the mouth of which is" downwardly disposed. Threaded upon the mouth ofthe chamber 5 or otherwise secured thereto is a. carbid receptacle (i. Threaded to the smaller end of the gas chamber 5 is a lower water receptacle 8 which is of funnel shape, the. mouth of the receptacle 8 being upwardlyv disposed, the threaded connection between the chamber 5 and the receptacle 8 being designated the reference character l. Threaded to the upper end of lthe lower water receptacle 8, as shown at 9,v is a reser`1 voir l0, the top ll .of which is provided with n nipple l2, receiving a cap lll, into which is threaded a needle valve l5, provided at its outer end with a turning head 16; the pointed extremity of the needle valve 15 is received within a seat 17 formed at the axis of the lower water receptacle 8. Removably mounted in the lower portion of the water receptacle 8 and disposed below the seat 17 isa retaining member 18, carrying a drip pipe 19, projecting into a distributing' tube 20, the same being perforated, and beine' secured at its lower end to therbottorn of the carbid receptacle 6. Depending from the top 1l of the reservoir l0 is a foraminous strainer tube 2l. Access is had to the interior of the strainer tube by means of a removable plug 22 which is mounted in the top l1 of the reservoir l0.

Extending from the gas chamber 5 is, a deliverypipe 23, passing through lan opening 23a into the interior of the reflector 3, the free end of the pipe 23 carrying aburner 24 which may be of any desired type.

Communicating with the interior of the reflector 3 and extended rearwardly from the reliector is a funnel 25, communicating with an upright pipe 26, the latter having a transverse extension 27 which communicates with a U-shaped circulating pipe 28, the latter being extended downwardly through the top ll of the reservoir l0 into the reservoir, the free end 29 of the cireu lating pipe 28 extending upwardly through the top l1.

Guides 30 in the form of rods are secured. to the base 1, the guides 30 passing upwaidly through the opening 23a in the relie ctor 3. Mounted by means of brackets 3la toslide on the guides 30 is a trough shaped shield 31 shown in Figs. 1, 8 and 7, and open at the back. A shaft 32 is journaled for rotation in bearings 32a upon the base 1, the shaft 32 being provided with a forwardly extended finger 33 lying beneath the lower end of the shield 31. At one end of the shaft 32 there is an upstanding crank arm`34a ,Tyhe operation of the device above described is as follows The carbid is placed within the receptacle 6, about the perforated tube 20, and, the plug 22 being removed,

waterjs poured into the receptacle 8-10,

,thestrainer tube21 exercising its obvious function. When the needle valve is ro- Vtat-edn'through the medium of the head 16,v

the oint of the needle valve is retracted out of t e seat \\17, so that water may pass into the drip tube 19 and from the drip tube 19 into the distributing tube 20, the water passing through the perforations of the tube 2O and acting upon the carbid which is in the receptacle 6. The gas which is formed with- .in/ the receptacle 6 will accumulate in the funnel shaped gas chamber 5, and pass thence, by way of the pipe 23 to the burner 24. To prevent an overheating of the reiector 3, the'same is provided with ventilating apertures which may be ositioned at any desired points in the re ector. The heated air which is located within the contour of the reiector 3 will pass into the funnel 25 and thence by way of the upright f pipe 26 and the extension 27, into the U- raise and to lower the shield 31 upon the guides 30.

The shield or screen 31 is a mere troughshaped element, arched transversely away from the vertical axis of the burner 24. Then the shield or screen 31 is raised, the same moves upwardly in front of the burner 24 but does not extinguish the iame. When the flame at the burner 24 is under full head and when the screen or shield 31 is depressed, suliicient heat will be generated to effect the desired result, even though the shield be lowered. When a light is not required, the flame at the burner 24 may be turned down to a considerable degree, under which circumstances the shield 3 1 may be raised, thereby directing the relatively small amount of heat generated directly into the funnel 25.

Having thus described the invention what is claimed is 1. In a device of the class described, a reflector; a'burner within the contour of the reector; a carbid receptacle and a water reservoir communicating with the carbid receptacle; means for admittin air tothe reiector; and a combined venti ating and water heating pipe opening at one end through Y the reflector above the burner andat its other end provided with a return bend extended into the reservoir and having an open end discharging outside of the reservoir.

2. In a device of the class described, a reiector; a burner within the contour of the `,reiector; a carbid receptacle and a water reservoir communicating with the carbid receptacle; a pipe opening into the reflector above the burner and extended through the water-receptacle; and a shield movable in front of the burner, the shield constituting means for directing heated air from the burner to the pipe. f

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

WILLIAM R. THITRSTON.
