No. 496,372. Patented Apr. 25, 1393'.

UNITED STATES PATENT OFFIcE.

LAWRENCE O. THORNE, OF ROCK FALLS, ASSIGNOR OF ONE-HALF TO JOHN V. EMMITT, OF STERLING, ILLINOIS.

IGNITION-CHARGER FOR GASOLlNE-STOVES.

SPECIFICATION forming part of Letters Patent No. 496,372, dated April 25, 1893.

Application filed August 27, 1892.

To all whom it may concern/5 7 Be it known that I, LAWRENCE O. THORNE, a citizen of the United States, residing at Rock Falls, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Ignition-Chargers for Gasoline-Stoves; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention is designed to furnish means of preliminarily heating the burners of a gasoline stove to such temperature that the latter may thereafter change the oil into gas in the usual mode.

The chief, if not the only, objection to the gasoline stoves now in very general use, is the obnoxious smoke and stench which seems to be inseparable from their operation. As at present operated, the burners of gas generators are preliminarily heated to a temperature sufficient for their subsequent operation, by means of oil deposited or drawn into a. small cup under said burner. The oil thus deposited is ignited, and the heat therefrom, passing up against the burner, raises the temperature of the latter to such a degree that thereafter the oil, in passing into said burner, is by the latter changed into gas and consumed. When the oil is deposited inthe ignition cup aforesaid,'beneath the burner, the burning thereof is simply the burning of oil, not gas, and such burning being in the open air, a large proportion of the carbon in the latter is set free without combustiomand deposited in the form of soot or grease on the stove and adjacent furniture, and parts of the building. The stench, which is the usual accompaniment of the burning of gasoline, arises from this preliminary burning of the oil, and such stench remains in the atmosphere even after the oil in the cup has been entirely consumed. As the subsequent combustion in the gasoline stove is of gas, no perceptible smoke or stench arises therefrom. v

It is the purpose of myinvention to sub- Serial No. 444.305- (No model.)

stitute alcohol for the oil in this preliminary heating, and as alcohol, when burned, emits no smoke or stench, to thereby avoid the obnoxious features aforesaid, consequent upon the mode above mentioned. For the reason that alcohol is more expensive, it is desirable that no more be used, in any instance, than is actually necessary to accomplish the purpose intended.

The object of my invention is to provide means for delivering to the aforesaid ignition cup, alcohol in measured quantities only.

To that end my invention is adapted to be attached to the gasoline stove at some suitable andconvenient point thereon,and to consist of an alcohol reservoir, communicating with the aforesaid oil cup, and measuring and discharging mechanism, intermediate said reservoir and said cup, whereby the required quantity of alcohol, and no more, may be readily deposited in said cup at each use of the stove.

As the gasoline stoves in use vary in construction, and such construction and their mode of operation are well known, I do not deem it essential to show or describe any part of the stove, and will limit the description herein to the construction, relation, and operation of my invention. I attain the object hereinbefore named,- by the mechanism illus- 8o trated in the accompanying drawings, in which I Figure 1 is a side elevation of my invention. Fig. 2 is a vertical section of a portion of the intermediate parts. Fig. 3 is a detail of the air escape through the upper valve. Similar letters refer to similar parts throughout the several views.

M is a vertical tube united at its lower end to a horizontal piece of lead pipe J, having a 0 copper nozzle K.

N is an ordinary form of clamp, clasping the tube M near its lower end, and adapted to rigidly seat said tube at any proper locality on the stove.

The lead pipe J afiords means of turning the nozzle K in any direction, to cause the latter to discharge into the cup under the burner present in all gasoline stoves, and which I have termed the ignition cup.

D is the alcohol reservoir seated on the upper end of the tube M, and of sufficient size to contain a gallon or more of alcohol.

A is a funnel seated in the upper surface of and communicating with the reservoir D, as a means of filling the latter. The funnel A is provided with a stop-cock 1, to preclude evaporation from the interior of said reservoir. B is an air vent also provided with a stop-cock 2, to be opened when filling reservoir D.

C is a float having its stem, 3, projected upwardly through the top of the reservoir D, to indicate the height of the alcohol in the latter.

E and O are valves seated transversely, a suitable distance apart, in the tube M, and each provided with transverse openings, 4, adapted to register with the opening in the tube M when turned in the line thereof.

H, II are levers rigidly seated on the axis of valves E and 0, respectively, outside of tube M, and pivotally connected at their outer ends to the vertical arm G, which latter is provided about centrally with a suitable handle P. The valves E and O are so seated, relatively to the tube M, that but one of said valves register with the opening in said tube at a time, and when one of said openings is in communication with the interior of tube M, the other is cut off by having its ends turned against the wall of the tube M.

The operation of this part of my invention is as follows: \Vith the valves in the position shown in Fig. 2, opening 4 in valve 0 has registered with the opening in tube M, and is in position to permit the escape of the contents of said tube above said valve into said ignition cup. By a short downward movement of the arm G, the opening, 4, of valve 0 is thrown over against the side of tube M, which closes the latter opening, while the opening 4 in the upper valve E is caused to register with the tube M, and thereby permits sufficient of the alcohol contained in reservoir D to fall down into, and fill that portion of the tube M above the valve 0. The apparatus is then in a condition for use, and the nozzle K being normally inserted in the ignition cup aforesaid, a short upward movement of the arm G throws the valves E and 0 into the position shown in Fig. 2, and arrests the passage of alcohol from said reservoir at the upper surface of the valve E, and permits the alcohol contained in the tube M, between the aforesaid valves, to pass through valve 0, end J, and nozzle K, into the ignition cup. If desired, the arm G can then be lowered, and a charge for the next occasion held within the tube M between Valves E and O; or the arm G may be given two movements on each occasion of the use of my device-one downward to load the interval between valves E and O, and one upward to discharge the quantity thus measured between said valves.

A short, horizontal tube F, closed at its outer end and communicating at its inner end with the tube M, is seated about midway on the latter, and provided with a piston R, having a rod S projected outward through the outer end of the tube F, and by moving the piston R in or out, the capacity of the tube M between valves E and 0 may be increased or diminished as maybe desired for different sized ignition cups.

Referring to Fig. 3, 5 is an air vent passed diagonally through the wall of the tube M. and the valve E intersecting opening4 therein, and adapted to permit the escape of the air from the interval, between valves E and 0 to accelerate the discharge of alcohol through valve 0.

The advantage of my invention is that the precise amount of alcohol to be used in each instance can thereby be predetermined, and none wasted. Also the aforesaid smoke and stench can be avoided.

My invention is applicable, as an ignitor, to all instances where offensive oils are vaporized by heated burners.

\Vhat I claim as my invention, and desire to secure by Letters Patent of the United States, 1s-

1. In an ignition charger for gasoline stoves, the combination of an alcohol reservoir D. placed at a suitable elevation,a tube M. communicating, at its upper end, with said reservoir, and extending downward therefrom and provided with a lower end J. adapted to communicate with the ignition cup of said stove, partially rotating valves E and O, seated transversely, a suitable distance apart, in said tube M. and provided with transverse openings 4, adapted to separately register with the interior of said tube M, levers II. H. rigidly seated respectively on the axes of valves E and O. externally to tube M. at different angles with the openings 4. therein, respectively, and arm G. pivotally attached to the outer ends of levers H. II. substantially as shown and for the purpose described.

2. I11 an ignition charger for gasoline stoves, the combination of the tube M. separately registering valves E. and O. seated therein, a suitable distance apart, side tube F. con nected to, and communicating with the tube M. between the localities of the aforesaid valves, and a piston R. provided with a rod S. adj ustably seated in tube F. whereby the capacity of tube M. between valves E. and O. can be optionally increased or diminished, substantially as shown and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

LAWRENCE C. THORNE.
