ALCOHOL-GAS LAM'P.

Specification of Letters Patent.

Patented April 21, 1903.

Application filed February 9, 1907. Serial No. 356,542.

. Be it known that I, HENRY G. Lni'ive, a

citizen of the United States, and resident of A the borough of Manhattan, city, county, and

State of New York, have invented certain new and useful Improvements in Alcohol- I Gas Lamps, of which the following'is a specification, accompanied by drawings.

This lnvention relates to gas lamps,-more particularly to alcohol gas lamps, and the objects of the. invention are to produce a wickless, springless, valveless alcohol gas lamp,which can-be lighted and operates automatically thereafter until the full volume of flame is 'roduced, which flame can then be regulate by hand. I

Another object of theinve'ntion is to produce'a non-explosivelamp, and one which will burn denatured alcohol, any liquid which contains alcohol, or any liquid which, can be Further objectsof the invention will hereinafter appear and to these ends the invention consists of an alcohol gas lamp for carry ing outthe above .objects embodying the features of construction, combinations of elements and arrangement of parts having the general mode of operationsubstantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which,.

.Fi ure 1 is a'vertieal sectional view of a simp e form of lamp embodying the i-nv'ention; Fig. 2 is a top plan view of thesame;

Fig. 3 is a side view of a modified form of "lamp; Fig. 4 is a vertical sectional view-,ot

5 is a top plan view; Fig. 6 is an Figenlarged etailvertical sectional view of the charging valve; Fig, 7 is a detail plan view Of the lower air valve and spoon.

- It ferrin'gto the drawings, A represents the body of the lamp, which may be of any --suitable construction to form a reservoir, y'providedwith the inlet opening B, having the. removable; cap C, preferably screwthreaded. .Acombustion chamber '1), made of suitable metal, preferably copper extends vertically through the central portion of the body A, and is opento atmospheric air at both topand bottom. Gas pipes E, of'which "there maybe any desired number, in this in- ;stancethree being shown, are arranged to connectjthe dome-of the alcohol chamber with thelowerportion of the open combus tion chamber, and as shown extend through apertures in the lower portion of said chamber. These gas pipes E have open upper ends F, while the lower ends G are also open and preferably extend upwardly to induce an upward draft for the gas. The openings G are of such form and size that the ambunt of gas consumed may be predetermined.

Suitably secured below the combustion chamber 1) on a pivot D is a primary charging spoon 11 having a bowl and provided with the lip J which forms a convenient? means of lighting the necessary amount of alcohol contained in the bowl I to start the lamp in operation. As shown, there is a substantial space between the upper edge of the spoon H and the lower edge of the combustion chamber to all'ord draft room for the air to support combustion.

Means are provided for controlling the amount of air supplied for combustion, andpreferably this same means is utilized to control the filling and lighting of the combustible in the spoon H. As shown, an air slide gate K in the form of a disk is pivoted on the stud'L extending downwardly from the body portion A of the lamp, and this gate is, in

this instance, provided with an extension 0, which is adapted to lie over and cover the lip J of the spoon II when the gate entirely closes the lower end of the combustion chamber D. A suitable guide lip P is provided to support one end of the gate and permit it to slide back and 'lorthbeneath the combustion chamber D, but still be maintained tightly.

against the lower ed e of the combustion chamber 2. Preferably a handle Q of wood or other suitable non- "onductingmateri'al is provided adapted to us attached to and detached from the gate K as by means of a screw-threaded socket.

- To start the lamp in operation, the body portion is iirst tilled with alcohol, preferably up to the levelof the bottom of the filling screw and it will be seen that the up or openings F of the gas pipes E are locatec in the dome of the lamp where the gas would be formed, and above the normal level of the liquid. The gate K is position'shown in Fig. .2 to open the lip J, and a small quantity of alcohol is poured into the bowl I of the spoon II through the lip J, lilling the lip J and the body I with liquid, to which a match is then touched to ignite the liquid.- Or else the spoon may be swung outward on its pivot and then moved into the v filled, then no gas collects in the dome of th spoon swung back and ignited. the combustion tube'l) carries the flaming liquid upwardly, warming the sides of the combustion chamber and the exposed ends of the gas tubes, which causes the liquid in the body A. of the lamp to give oll' gas. This 0 body portion A and passes downwardly through the gas pipes E, and upwardly out through the op enings G, Where it is ignited by the flames which cause the gasification. The lamp then continues to burn and the flame increases until the full volume of flame is reached, which liame continues to heat the walls D or" the combustion chamber, and the action-is automatic thereafter. The combustion largely depends upon the amount of air admitted to the lower portion of the combustion ehan1- bar, and this may be controlled by the operation of the gate K. I

When the valve K entirely-closed and no volume of air is admitted through the lower portion of the combustion chamber, the flame from the tubes E will burn very low, but may be maintained by the air passing down from the top of the combustion chamber. The flame will be so small, however, that there will not be sullicient heat generated to continue gasifying the liquid in the body A of'the lamp unless this liquid is of a very gaseous nature.v By admitting the desired volume of air to the lower portion of the combustion chamber, the desiredamount of combustion may be obtained to make a thorough and economical mixture. of air and gas. This'lamp is non-explosive because there are no valves to shut off communication fi'om the interior of the lamp to the outside atmosphere, and the, dome of the charm her 'A is always open to atmospheric air via the. as tubes. 7 v

T e projection O on the gate K serves the pur ose of preventing theiilling of the or the lighting of the liquid in the 0011 and lip J when the gate K is closed. norder to pour liquid into the spoon and light it, the gate must be opened which is the normal osition for the gate during the operation of the lamp. According to this device, ifthes oon is not swung on its pivot, it cannot befilled or lighted unless the gate is opened and thus accidents are avoided.

plpes E'm this instance, are provided with In Figs. 3, 4, 5, 6 and 7, amodification of th invention is shown, in which automatic means are provided for placing a charge of H, and other features are shown in this modification which will be described. The bod Aofthe lamp is provided, "as in Figs. 1 an 2, with a 1 central combustion chamber D, which in this instance is preferably constructed with a co'rrugated ortion S, which increases the radiation sui ace and permits freer expan- The The draft through Llower the form of slots of suitable l l i l l l l g i l I body ceases openings which are preferably in size, having one onnc dimension so that the flame is seated clo. to the burner orifices. Any other suitable form oi burr r tip maybe used for these ends to forn'i flames actors and to obtain the combustion at proper height have the best L in the body portion A.

According to this modification I prefer to utilize the spoon lite control the volume of air supplied to the combustion chamber: through the lower end the spoon ll provided as beforewith the the lillio lip J, which in this instance is made of l sullicient depth to allow vertical movement of the spoon without interfering with the charging valve. The body portion I of the spoon is i3 ably provided with a thicl encd cup d disk I, having beveled edges a p r. ground to lit the beveled lower ed e t or the eon'ibustion tube D The spoon H is hung, shown, on the rods 0 which sui .iy connected to the icon, in this instance with adjustable nuts d, although other; desired means may be provided for this purpose. The rods c extend upwardly through sleeves e, which extend through-t ie body A of the lamp and are open at both ends, but ti htly secured to the top and bottom of the body The upper ends of the rod 1; are bent at an angle to form hool' These bent endsf or'the rollers if prcvdcd are cam 5/, which provided on. or in the ring it, which encircles the upper end of the combastion tube 1) and is provided with an operating handle 2', bv means ofwhich a ring 7i may be rotated. l he cam g is provided with high and low portions so that as the ring it is rotated the rods move up and down and move the spoon vertically to or from the lower openi g ol the combustion tube l). this means ti; closing spoon H is controlled from the top of the lam and the thickened portion be he d tightly against 3 l ver portion of the tube Dto entirely s at oil the air,

Automatic means are provided for chargwith substantially the exact uid necessary to start the i iceording to the present o tube is provided extending Jody portion A of the lamp and see red tightly to the top and bot'ton walls. This tube is provided with a number of small holes lc wl'iich communicate with t ie interior of the body A, and permit the liquid insaid b0 pass into the tube. Communicating with tl 9 lower end of the tube is a charging tube in this instance shown located beneath the body portion A and encircling the coml'austion i), although this charging ing the spoon quantity of ii in the combustion chamber to. gasil'vin'g efiect on the liquid and in this instance adapted to travel in the ring any desired posi- -form of a cylinder connected to the piston rod 1' extending upwardly through the tube and provided with a button 8 at its upper end. Between said button and the shoulder t in the tube 9' is provided a compression spring to which normally holds the piston q in raised position to permit the liquid to pass from the'body of the lamp through the apertures k'into the charging tube. The piston q is preferably provided with packing rings to form a gas tight iston. The valve p is connected to the nu v which extends through a gland w in the lower end of the piston q and is provided with a head as, between which head and the lower end of the piston q is arranged a compression spring g which normally maintainsthe valve p closed. Means are provided for operating t ie charging valve automatically by means of the handle i, and

as shown, said handle is provided with a button 2 adapted to cdoperate with the button 8.

In the operation of the device when the handler; i turned into position to bring the button {over the button 8, the piston q is forced down, closing the apertures la. The further downward movement of the piston forces the head q downward, thereby opening the valve mm permittingthc contents of the tube '1 to flow into the spoon. Asuitable vent is provided for the charging pipe Z in order to permit the liquid to'ilow into and out of said pipe and to take care of any gas which may be generated in the the heat in the operation of the amp and in this instance a vent pipe-2 is provided communicating with the tube ,1 and with the dome of the lamp inside of the top.

When the handle t is moved away from the button 8 the springs restore the mechanism to normal position, thereby closing the valve 7) and opening the a )erture/r to permit another charge of liquid to flow into the charging tube 1. The movement of the lever away from the button 8 also tends to move the spoon II upward, dueto the travel of the 11 per ends of the rods 0 from the low to the -high portions of the cam g. When the charge in the spoon H is lighted, the walls of the combustion chamber are heated s'uiliciently to gasity some of the li uid in the body A, and the gas flows down t irough the gas t'ubcs l) and is ignited at the orifices G,
