TORCH.

SPECFICVATIONfforming part of Letters Patent No. 284,346, dated September 4, 1883,` 1 v Application filed May24, 1883. (No model.) I

To a/ZZ` whom t may concern:

Be it known that I, HENRY WELLINGTON, of Brooklyn, county of Kings, andState of New York, haveinvented certainnew and` useful Improvements in Torches, of which the following is a full, clear, and exact description` reference being had to the accompanying draw-j ings, and to thef'letters of reference marked thereon. y Myimprovements have relation to torches,

especially such as are intended to be carried v aboutin the hand, burning hydrocarbon or other easily-vaporizing material, and employed for purposes of burning paint or varnish, for heating ordinary vapor-burners before lighting, and for other purposes in con-` l nection with heating and illuminating.

t an economical consumption of burning ma-' simpleand efticientmeansotconnecting the y The object of `my invention is to produce a simple, compact, safe, and durable torch wherein thepre'ssure upon the liquid. within the fount or reservoir is produced by compressed air, and which will afford an intense heat with terial; to simplify and .improvethe construction of the pump and the valve through which air is admitted to the reservoir; to provide perforatedguard with the burner;` to provide non-conducting finger-pieces lfor the needie-valve; to locate and arrange the supplytube and packing-tube leading to the burner,

so that a supply of fuel will always be provided for the burner, (when the air-pressure is on,) and so that the packing may be easily removed; to provide a convenient place for scratching matches; to simplify and improve `the means of securing the "handle in place, i and to secure other advantages, as will hereinafterappear. To accomplish all of this, my improvements involve certain novel and usefulpeculiarities of construction, relative arrangements or combinations of parts, and principlesof operation, all of which will be herein first fully described, and then pointed out in the claims.` w v In the accompanying drawings, forming part of thisspecication, Figure l is a side eleva- ,tion of `myimproved torch.A Fig. 2 is a plan of the burner detached from the other parts, the ngerpiece upon the needle-screw being shown in section.- Fig. 3 is an axial section of the handle.

ofthe torch, showing the parts assembled for use. `Fig. 4t is an enlarged sectional view, showing the construction and arrangement of the air-valve.

B is the bottom piece, having a narrow bead around its top, into which the lower edge of the reservoir-body is bent or turned, the two pieces 'being secured by solder or `otherwise afterthe pump is located and iiXed in place.

O is the pump-barrel, located in the lower part of the reservoir and projecting through one side thereof, so as to form the lower brace pump-barrel, it is connected with the oil-supply tube L by means of a dividing-plug, as c, and the tube L is carried through the opposite wall of the reservoir. The joints between the walls of the reservoir and the pumpbarrel and supply-tube are secured by solder,

` which prevents leakage and sustains the parts in a solid and substantial manner, so that To brace the inner end of the the Iworkingzof the pump-piston will in no A way disturb them or injure the joints, as frequently occursin constructions wherein the Ypump-barrel is not sustained at both ends.

D is the piston-rod, made solid, and provided at its inner end with a cup-piston, el, of leather or other elastic materiahthe cup being turned toward the inner end of the pumpbarrel, as shown in Fig. 3.

Upon the outer end of the pump-barrel is the ring i, which receives the removable centrally-perforated screw-plug, c, throughwhich the piston-rod D passes loosely, intorder that air may be` admitted around the rod. The

ring 'i is secured upon the end of the pumpbarrel by swaging the end of the latter. This makes asimple and secure joint and facilitates the insertion o`f the cup-piston, the front opening in the pump-barrel being thus made amply large and quite smooth.

Upon the upper part of ring i is a screw- 4threaded disk, h, to receive the correspondingly-threaded lower end of thevertical piece H of the handle. 'This piece, being turned y y 55 In all these iigures like letters of reference,

down to its seat on the disk, is held at top by the brace I, the same being soldered to the top of H, and also upon the reservoir. Through the brace I and the top of the reservoir is the opening through which oil or liquid fuel is admitted to the interior, the opening being securely closed by the removablescrew plug or stopper K, the screw-threaded seat for which is formed in the end of the brace, as shown.

Upon the inner end of the pump-barrel is secured in any substantial manner a seat, c, for the valve through which air is admitted to the reservoir. It is essential that this valve should freely admit the air and automatically close against the downward or outward passage of liquid from the reservoir. Over the perforation leading through the seat a, I place a thin disk of metal, b, in a suitable recess cut for it. Over this is a disk of elastic material-.-v such as' a compound of glue and glycerine or other oil-resisting material (represented at 1)- and upon this is a protecting-plate of metal, g. Theexterior of seat a is screw-threaded to receive the cap 7c, the same being perforated at top and made to hold the valve-spring Z in place. The elastic disk, under the action or pressure of theI spring, securely closes the airopening in the seat, the same being protected against wearing action of the spring by the upper metallic disk and by wearing action upon the Valveseat by the lower metallic disk.

The pump and valve being thus constructed,

- when the piston is drawn out,the `valve is automatically closed and air finds its way past the elastic cup on the end of the piston-rod or plunger. Then upon forcing the plunger inwardly the air in advance of it is compressed, elevates the valve, yand is forced into the reservoir, wherein it may be compressed to any desired degree. The pipe L, throughwhich oil is forced from the reservoir,is perforated at the bottom, as at x, so that as the instrument is inclined during use the oil or liquid will not be liable to uncover the orice, and thus fail to be forced out through it.

Upon the exterior of pipe L is the elbow m, which also receives the packing-tube M, leading to the burner, the tube being supported at top by a suitable brace, n. Thistube is intended to be packed with any granular or 'iibrous material, and may be easily removed for cleaning or repacking. Upon the top of tube Mis screwed the drip-cup N, and this receives the burner O, which in turn supports the perforated shield or guard I. The under surface of the drip-cup is roughened, as shown in Fig. 1, and made to supply a convenient object upon'which to scratch matches.

The burner is of simple form, having the heating -rods q q and cross piece r. This burner might be otherwise formed, inasmuch as its particular construction is no essential part of my invention.

The under side of guard P is notched out,so as to fit around the neck of the burner, and

this, together with'the screw u, holds the guard firmly in place.

0n the underside of the perforated guard I is an elongated slot, c, to admit the passage of the flame from the drip-cup in the process of lighting the burner, which is accomplished in the usual way by burning oil or liquid in the drip-cup. f

As will be readily understood, the needlevalve R is used to regulate the size of the iiame, and usually becomes highly heated. To prevent burning of the fingers, I form the outer end of the 'valve-stem into a ring, and in this ring locate two wooden buttons7 as S S, each having overhanging edges, and secured together by the central screw, as plainly shown. This forms a good non-conducting finger-piece, and is of marked advantage in connection with the valve.

As will be readily understood,'the air above the supply of oil or liquid in the reservoir is compressed by a few movements of the pumppiston, and the compressed air furnishes a constant supply of fuel to the burner, the same being driven up with force sufficient to produce an intense heat. The construction of the burner and arrangement of the perforated guard are such that a proper supply of air will be mingled with the burning vapor.

As shown in Figs. l and 3, the guard and burner are vinclined upwardlyfrom the axis of the reservoir, and this is the preferred way of mounting these parts, so that the flame may Jbe most advantageously employed while the ytorch is moved up or down or inclined in the hand.

. The torch thus constructedis found in practice to be simple, durable, and thoroughly efficient, and to admirably answer the several purposes or objects of the invention, as previously set forth. Y

Having now fully described my inventiom.

what I claim as new7 and desire to secure by Letters Patent, is v 1. In a torch of the character herein set forth, the air-pump having the solid pistonrod with an elastic cup-piston applied thereon, the pump-barrel being sustained at both ends and connected with the vertical handle, the same being combined with the reservoir, substantially as shown and described.

2. In a torch, the combination, with the pump-barrel mounted and sustained within the reservoir, substantially as explained, of the air-valve located upon the pump-barrel within vthe reservoir, said valve being composed of the elastic disk protected on both sides by metallic plates, and operated upon by the spring, substantially as shown and described.

3. In combination with the pump-barrel l extending through one side of the reservoir, the oil-pipe connected with said pump-barrel, extending through the opposite side of the reservoir, and perforated for the admission of @oil to it, substantially as shown and described.

4. In combination with the burner, the neet connected with the reservoir and 284,346 t Y ls the burner and drip-cup, substantially in the t manner and for the purposes setforth.

6. In combination With the burner, the dripv v cup mounted thereunder and h aving its under surface ribbed, for the purposes and objects named.` l y 7. In a torch, the Vertical handle, threaded at bottom and secured at that point upon a 2o threaded ring applied upon the pump-barrel, t

-the same being combined with the top brace secured to the reservoir, and having the oili hole therethrough, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two Witnesses.

HENRY WELLINGTON.
