PREHEATING MEANS FOR VAPOR-BURNERS.

SPECIFICATION forming part of Letters Patent No. 653,924, dated July 1'7, 1900.

' Application filed October 31, 1899. Serial No. 735,420. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM W. WILSON and JOHN IV. TILSON, citizens of the United States, residing at Dallas, in the county of Dallas, State of Texas, have invented certain new and useful Improvements in Generators for Vapor-Burners, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a generator for vapor-burners, and particularly to a device located within the feeding-reservoir of the burner and adapted to generate at one operation SllffiClGDlJ vapor to heat, when ignited, the main burner fed from said reservoir.

The invention has for one object to provide a structure whereby'the reservoir can only be filled to a predetermined extent, thereby leaving a space above the body of liquid in which vapor may be collected and fed to the vaporizing or heating burner.

A further object of the invention is to provide a construction of parts by which the generating operation may be continued until the liquid contained in the reservoir is completely consumed, and also to facilitate the operation of the generating apparatus to render the same simple and convenient in use.

Other objectsand advantages of the invention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective of the liquid-reservoir with the invention applied thereto, and Fig. 2 is a vertical section through the same.

Like letters indicate like parts throughout both figures of the drawings.

In the drawings the letter A designates a reservoir of any suitable material or conformation which is adapted to be filled only to a predetermined percentage of its total capacity. For instance, as shown in Fig. 2, the filling-spout permits the liquid used to fill only one half of the capacity of the reservoir, leaving the upper half as a generating-chamber for gas. The liquid used in this reservoir may be gasolene or any other Suitable fluid used in vapor stoves and which will carburet air coming in contact therewith and produce a heating-gas. For the purpose of producing this generation of gas a verticallymovable bell or dome B is located Within the reservoir A and provided with a closed extension B, communicating with the upper portion of the dome. This extension passes through the top A of the reservoir,

and the joint between the same is suitably packed, as at A to provide a substantially air-tight connection between the movable extension and top. Now it will be seen that upon raising the dome B air will be drawn inward through the heater-pipe O by the suction of the raised dome, and coming into contact with the liquid adhering to the walls of the dome quickly becomes charged or carbureted, so that the dome in its raised position contains beneath the same a body of gas. The dome is weighted to any suitable extent and in its return movement forces the gas beneath'the same outward through the heating-pipe 0, extending within the extension B to the burner O, which is adjacent to the burner D, carried by the main feed-pipe D, and consequently heats such burner to vaporize the liquid fed thereto and produce the desired flame.

For the purpose of raising the dome and extension thereof we have provided a support E, carrying at its upper portion a bearingwheel E, over which a suitable raising-chain E passes, and is provided at a convenient point with an operating-handle E so that it is only necessary to raise the dome by means of the chain in order to start the generating.

apparatus,which when released will force the gas to the heating-burner O.

For the further purpose of utilizing to the largest possible extent liquid Within the reservoir and at the same time producing the generating of gas there is provided a central chamber F, extending parallel with the side walls of the reservoir A, to form a seal for the lower portion of the dome B. The top of this chamber F is suitably inclined to direct any liquid thereon toward the sides thereof and provided with apertures F by which the chamber may be supplied. The main feedpipe D for the burner D leads from the lower portion of this chamber. It will be seen that the generation of gas may proceed by reason of the liquid seal to the dome so long as there is any liquid remainingin the chamber F. The filling-spout A is provided with a suitable closing-cap A and the lifting-chain is connected with the extension B by means of a pivoted bail E. It will be obvious that the generation of gas cannot be successfully accomplished if the reservoir be filled to such an extent as not to leave a sufficient space for thecollection of the carbureted air. It is therefore necessary to provide. a filling spout single feed-pipe, if so desired.

It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination with aliquid-reservoir, of a dome adapted to be reciprocated therein, a filling device communicating with said reservoir at a point below the top thereof, whereby the reservoir can only be filled to a predetermined proportion of its capacity, a chamber beneath said dome having openings in its top and communicating with a vapor-burner,

means for raising said dome, and a pipe communicating with the heating-burner and with said dome; substantially as specified.

2. The combination with a liquid-reservoir, of a dome adapted to be reciprooated therein, a filling device communicating with said reservoir at a point below the top thereof, whereby the reservoir can only be filled to a predetermined proportion of its capacity, a vertical closed extension from said dome passing through the top of said reservoir, a bearingwheel supported above said reservoir, a flexible connection with said extension extending over said wheel and to a point below the reservoir, a chamber beneath said dome having walls parallel with those of the reservoir and an inclined perforated top, a feed-pipe communicating with said chamber and with a vapor-burner, and a feed-pipe extending within said extension and to a heating-burner; substantially as specified.

3. The combination with a reservoir, of a dome therein having a vertical extension projecting through the top of said reservoir,

means for raising said dome and extension,

a chamber beneath said dome having walls parallel with said reservoir and an inclined perforated top, a feed-pipe leading from said chamber to a vapor-burner, and a feed-pipe extending from said extension to a heatingburner; substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
