PAINTERS BURNING-LAMP.

SPECIFICATION forming part of Letters Patent No. 251,075, dated December 20, 1881.

Application tiled July 30, 1881. (No model.)

To all whom t may concern y Beit known thatLUI-IARLES STALLMADGE, of Cincinnati, Hamilton county, State ot' Ohio, haveinvented certain new and useful ImprovementsinPaintersBurning-Lamps,ofwhichthe following is aspecification.

My invention relates to that class of lamps Aemployed by painters in the removal ot'pnint from wood or other material, the flame of the lamp being directed against and caused to burn the paint. This operation of burning the paint renders the latter soft and loosens its hold on the wood-work or other material to which it was originally applied, and enables it to be readily and easily removed by scraping, &c.

Myinvention contemplates theuse ofnaphtha or gasoline as the fuel for generating land feeding combustion.

The object of my invention is to provide a cheap, economical lamp, easily operated and applied, and effective in use.

The various features of my invention will become apparent from the following description.

In the accompanying drawings, Figure 1 is a view in perspective of a lamp illustrating my invention. Fig. 2 is a vertical central section of said lamp, taken in a plane passing through the longitudinal center of the burner; and Fig. 3 is a transverse section of the burner.

A designates the can or body of the lamp, which contains the gasoline. The can is preferably provided with the handle B. A tube, C, located within the can and open at its lower end, extends from the top of the can to within a short distance of the bottom of the latter. At the top of the can this tube is connected by a screw-thread, as shown, or in anyother suitable manner, to a suitable stop-cock, D, preferably of thekind known as neetlle-valve,a11d shown in the drawings, where c is the shell of the valve-seat b, inclosin g an aperture leading into the pipe or tube E, and d a valve whose stem d is provided with a screw engaging a female screw in the stem and operated by a nger or thumb piece, e. The valve D is connected to the tube E by a screw-thread, or in any other suitable manner, and this tube is connected in any desired manner, preferably by a screw-thread, as shown, to the tubular stem F, which is connected to the rear portion or forms a part of stem fof the burner H. The tube E is filled with packing', preferably ot' cotton.

The burner H consists ofthe usual rear portion,j', attached to stem F, and provided with a conduit or openingiconnected to the opening in stem F, and in its horizontal portion gradually` tapering forward to an exceedingly line orifice at the point 7L, where it entersthe cavity of the cylinder m of the burner. The tapering shape ofthe hole alfords a proper seat for the valve n, which is projected against said seat or retracted therefrom by any suitable means. In the present instance the means consists cfa screw-thread ou the valve-stem n', which engages a female screw-thread on the interior of portion f,- and the said valve-stem a is further provided with a thumb or finger piece for rotating it, and thus screwing it forward or backward. rlhe cylinder m is screwed, as shown, or otherwise suitably attached, to the portion f, and is provided at rear with the usual inlet draft-holes,p.

. Near or atits mouth or front end the burner m is constructed in a novel manner, so as to crowd or force a portion ofthe flame and burning gases (which would all otherwise issue from the cylinder) back against the rear portion of the cylinder, in order to heat said rear portion, including the valve portionf, very hot, and keep the latter at a high degree oftemperature. This may be accomplished in various ways-as, for example, by slitting longitudinally the end of the cylinder at several equidistant points on its periphery and bending the slit parts so as to come quite closely -together; but the preferable method of construction is that'shown in the drawings, and is as follows: The front portion of the cylinder m is internally cut away, making an annular recess, S, and a shoulder, t. Within this annular recess is placed an annular piece, K, whose outer or peripheral circumference is somewhat less than the diameter of the space inclosed by the cylinder at said annular recess, and the'auuular piece K is so secured as to be everywhere equally distant from the wall of the annular recess S, and thus an annular space, S', will be everywhere present around the annular piece, and between IOO that and the wall ot' the annular recess. In

the present instance the means for securing the annular piece K in position consists ot' two set-screws, te, one located on and passing through one side ofthe cylinder and the other located on and passing through the opposite side of the latter. Each screw engages a i'emale screw in the cylinder and impinges against and is preferably stepped into a step or recess in the adjacent side of' the annular piece K. (See Fig. 3.) These set-screws enable the piece K to be easily and quickly removed from the cylinder m for the purposes of cleaning or repairing the cylinder m, or cleaning or repairing the piece K, and can be as easily and quickly replaced in the cylinder. r1`he inner edge of the rear end of the annular piece K is preferably beveled oft', as shown, to deflect the flame and burning gases forward and toward the center ofthe cylinder, and is placed so that the outer edge of said rear end shall be quite near the shoulder t, and yet far enough distant to allow of the passage ot' a portion ofthe tlame and burning gases between the annular piece K and the wall of the recess S. The annular piece K is preferably made quite thick, and so that the surface-lines ot' that portion of the cylinder which is behind the iecess would, it' projected forward, pass through the center ot' the edge of the annular piece. rlhe object of making the annular piece thick is to present a greater barrier to the outward progress ot' the name, Src., and cause a greater portieri ofthe latter to be deliected toward the center ot the burner.

A novel and very convenient means for heating the cylinder my, valve n, stein a', and portionsfand F consists of the elongated cup basin-shaped receptacle M, located beneath said cylinder, valve, stem, and port-ions f and F, and suitably secured to the portion F. lt is vpreferably cast with the portion F, thus forming an inseparable portion thereof.

rEhe lamp, in order to be properly effective, must have some means whereby the gasoline may be rapidly forced from the car or body A up through the tubes C and E to portion F, and there be rapidly converted into gas and caused to rapidly issue at orifice h into the cylinder, thence kindled into liame, and be rapidly forced out through, and to some distance beyond, the mouth of the burner H. Such means is provided in the tube N, consistin g preferablyof a stift' portion ,2, attached to and opening into the can A, and having a stop-cock, 3, and a iexible portion,4, provided at its free end with a mouth-piece, 5. The other end of this exible portion is preferably so made that it can be readily relnoved from or attached to the end of the stili' portion 2. The free end of the flexible ltube may serve as a mouth-piece, when desired, without the addition of mouth-piece 5.

' The mode in which the afore-described lamp is operated is as follows: The can is rst filled by unscrewing stiff portion 2 of tube N from the can A, and pouring the gasoline through the orice 6 thus opened. The stift' portion 2 is then reattached to the can by being screwed into said oritice 6. The valve disclosed. The valve 3 is now'opened and the painter, applying his mouth to the mouth piece 5, blows through tube N, and continues so to do until he has condensed the air within the can-as t'ar as he is able conveniently to do by blowing with force. He then closes4 tube N by turning stop-cock 3 and opens valves d and a. The pressure of the condensed air within the can will force the gasoline into the burner, which gasoline will iiowinto and till the basin M. This gasoline is then set on re and permitted to lburn until the cylinder m and the valve n and portionsf and F are heated sufciently hot to cause any gasoline present in said valve and portions f F to be converted into gas. rI he gasoline thus expanding into gas issues with great force from the or tice It ot' valve n and passes into the cylinder m, where it is lighted, and the greater portion ofit passes out through the cylinder and extendsin an almost straightjetot Haine some six inches beyond the front ot'said cylinder m, and in a line parallel to the length ofthe latter. Another portion of the iiame passes into the annular space S and assists in the combustion, causing a blue flame. Another portion ofthe gas, in consequence of being detlected toward the center of the cylinder, crowds or reflects back a part of the flame and burning gases and forces them against the rear end of the cylinder and the face of portion f, thereby keeping the cylinderand portions fF continually hot, and causing these to generate gas from the gasoline passing up from the can.

The lamp is used by applying the llame to the paint to be removed. When the painter no longer needs to use the lamp he turns the valve D and cuts off the supply of gasoline to the burner and the flame is extinguished.

Those featuresof myinvention which consist of the device l'or detlecting back the flame, Sac., and the basin M, and that feature of my invention which consists in an apparatus for enabling the painter to condense the air in the can, as well as to rapidly force the gasoline through the tubes, while preferably used together, may be employed either in connection with one another or separately, as desired 5 or any two thereof can be used together, as desired. lf preferred, any other mode of condensing the air in the can or forcing the gasoline through the tubes may be employed-as, for example, an air-pump may be used; but I do not regard such as convenient or as useful as my device for the same purpose.

Any or all of the various features of my invention can be advantageously used for purposes other than those herein set forth. For example, they can be employed in gas-litters lamps, &c.

What I cla-im as new and of my invention, and desire to secure by Letters Patent, is
