LAMP.

SPECIFICATION forming part of Letters Patent No.f26`9,110, dated December 12, 1882.

` Application filed April 4, lese. (No model.)

To all whom' it may concern:

Be it known that I, ROBERT REACH, a citizen of the United States, residing at-Washington, in the District of Columbia, have invented a certain new and useful Improvement in Blast-Lamps, of which the following is a specificatiomreference being had therein to the My invention relates to an improvement in blast-lamps, and it consists in the combination `and arrangement of the parts, as hereinafter more fully shown and described.

In the drawings, Figure 1 is a central section. Fig. 2 is a perspective of the lamp-kit, the dotted lines showing position ot lamp when being conveyed. Fig. 3 is a side elevation, showing shield and cap as applied for painters use. Fig. 4. is a front view of vaporchamber, and Fig. 5 is atletail view of checkvalve. j

A represents an oil-tank, which is preferably cast in one piece, and provided with the filling-orifice c. The tank has inserted therein, and projecting through aclosed orifice in the cap F, the vertical tube C', connecting with the asbestus conduit C. Egress of the oil contained in the tank or vapor arising therefrom is regulated by the cock-valve f where it intersects the asbestus conduit C. The asbestus condunit C is packed with asbestus near the cock-valve j' and at the elbow f', which effectually prevents the oil from being forced too rapidly by the pressure of atmosphere in the top of the oil-tank into the vapor-generator.

In this connection I would state that I deem` Dauforths pateu ted non-explosive oil the only reliable non-explosive burning-duid, and that I use it exclusively for my blast-lamp.

The air-tube is provided with the mouthpiece e, and through this tube air is blown from the mouth into the tank.

In Fig. lis shown the altitude of the oil with which the tank is supplied, the altitude thereof at all "times admitting an air and vapor chamber above it. Air being blown into the tank, the oil and vapor are forced into the vapor-generator E, the ch eck-valve b', as shown in Fig. 5, preventing the escape ofthe gas from the air-tubewhen the blowing ceases.

The grate G has its bearings upon the inclined walls of the lamp-kit B. The lamp-kit is provided with the door H, through which the soldering-irons are thrust when placed on formed therein the vertical slot I, through which projects the vapor-burner when thelam p is placed in the kit, as shown by the 4dotted lines in Fig. 2, to render it portable. Tjhus it will be observed that the lamp-kit not only serves to render the blast-lamp conveniently portable, it being provided with the handle K, but that it also serves as a means of elevating the grate above the dame of the burner for heating the soldering-irons.

When such ordinary heat is required to be generated as is generally used by artisans the vapor proceeding from the orifice or burner It and thrown upon the grate G will produce sui'- iicient flame for the intended purpose. Such Va dame will be fcund ample to keep in proper heated condition the soldering-irons of tinners Y and plumbers,and my blast-lamp is especially adapted for such use, as it presents many ob vious advantages over the slow and more expensive method of heating solderingironsby charcoal.

The Shield D, slightly curved, is a piece of thin metal secured at the top ot' the vaporgenerator in recess d by the thumb-screw d, and projecting horizontally therefrom..

To the lower part of the vapor-generator E is pivoted the cup d, which is designed to catch the drippings of oil which are blown from the orifice of the burner It, and when an intense heat or enlarged flame is desirable the y oil blown through the oritice of the burner,

4and which is caught inthe oil-cup, is set on fire, and the iiame arising therefrom heats the vapor-generator, and thus greatly increases the quantity of dame generated and 'proceeding from the burner.

In scorching ofi' old paint the artisan discards the lamp-kit and .holds the lamp by the handle N,which is screwed into a female screw provided in the wall ofthe oil-tank, and thus secured it may be removed when not needed. The vapor-generator is formedof the slightlycurved metallicdisks g and g, the periphery of' the disks being united together, and in the center thereof having horizontal orifices, wherein are secured the asbestus conduit C and the burner 7l.. The clamp a', having re- TOO ess d for the reception of the shield D,is also provided with a vertical threaded orifice, wherein is located the thumb-screw d for holding the shield. This shield is employed as a means of diffusing a ilame over a large surface, and When it is employed the oil Ais blown into the vapor-generator E, and the ilame proceeding from the burner h heats the Huid in the vapor-generator and rapidly vaporizes it, and thus greatly enlarges the volume of ilame, proceeding from the burner, and

the dame in its ascent from the burner, is

spread over a large surface by means of the shield. This method of employing my device will be found very useful in the ordinary process of removing paint preliminary to repainting, which is the custom of coach-makers and others.

By this construction of my blast-lamp it will of heat which may be produced, the asbestus packing preventing a too great low of the luidunder air-pressure, and that the device may be usefully employed in manyof the arts.

Having thus described lmy invention, what I claim, and desire to secure by Letters Patent, 1s-

The combination of the oil-tank A, having oricea, lamp-kit B, having grate G, door H, and vertical slot I, substantially as shown, and for the purpose described.

In testimony whereof I afx my signature in presence of two Witnesses. l

ROBERT REACH.
