GENERATOR-TUBE AND FILLER FOR VAIOIL-STOVES.

Specification of Letters Patent. 7

Patented Nov. 28, 1911.

Application filed November 21, 1910. Serial No. 593,302.

-.To all whom it may concern:

estville, in the county of Hartford and State of Connecticut, have'invented certain new and useful Improvements in Generator- Tubes and Fillers for Vapor-Stoves, of which the following is a specification. I

My invention relates to improvements in generator tubes for liquid fuel vapor stoves, and the objects of my improvements are to provide an efficient interior cartridge or fillmg and to provide for cleaning the same and the tube when they become foul.

In the accompanying drawing: Figure 1 is a plan view of a vapor stove with one of my generator tubes applied thereto. Fig.- 2, is an enlarged central longitudinal section the generator tube, with a side elevation of the filling within the tube. Fig. is aside elevation of the combined core and handle for the said filling. Fig. 4: is an enlarged transverse section on the line ac w of Fig. 1.

My generator tubes are designed for vapor stoves which use liquid fuel that is fed by gravity into the generator tube from an elevated font.- As shown, the generator tube llvextends diametrically across the stove below a ring-shaped burner 5 that is fed from the font 6.

My improvement relates to the filling within the generator tube, which filling is detachable from the tube proper in its en'- tirety. Other fillings in this class of tube have been designated as cartridges. The manner of connecting the tube with the burner and font is not essential to my invention so long as a portion of the tube constitutes a compartment or chamber in which vapor is generated from the liquid fuel that is fed int-o the tube for supplying the burner with vapor. The tube proper 14: is of an old construction and in fact the stove herein. illustrated is made in accordance with the Varner Patent No. 968,435,

Aug. 23, 1910, with theeXception of the parts within the generator tube.

The main portion of my cartridge or fill-z ,ing is composed of a bundle of longitudinally extended wires. 'lhesebroadly speaking are old and well known as a filling for generator tubes.

I employ a core or foundation upon winch to build up thecartridge, the said core consisting of a twisted wire handle 8 and two make them practically a solid plug 11 at' that end. The outer wires are cut away or reduced to about half their diameter at the plug end for the full length of the said plug or soldered portion, so that the said plug is of less diameter than is the bunch of wires at the other parts of its length. That end of the generator tube which is occupied by the plug and from which the handle projects, is the influent end of the tube, and the plug is made of less diameter than the full bunch of wires in order to let the liquid fuel pass through the tube around the plug at this point into the spaces between the several wires and between the outer wires and the inner wall of the tube. The several wires are flexible and their ends farthest from the influent end of the tube are left free and unfastened excepting the ends of the two central wires 9. These terminate within the tube at a point beneath the ringshaped burner.

The filling thus far described will form 3 an eiiicient and operative device, but I prefer to add other parts as follows: A cleaner 12 in the form of a wire brush is secured to the shank 13 which shank is an extension'ot' the central wires 9, the said cleaner filling the tube at a point near the eflluent end thereof, leaving an open space or chamber within the tube around the brush shank be tween the said brush and the confronting ends of the wires 10. The -fuel enters the generator from the front branch 17,:1nd the end of the generator tube may be closed by remova le cap 18. The vapor is discharged from the tube through suitable and ordinary cock, that may be inserted into and secured to the generating tube. The handle 1.5 and needle 16 of the said cock in Fig. 1.

The general operation of the stove, in generating vapor from the fuel, the same as in other stoves of this class. iYhcn denaturcd alcohol is employed as the fuel in these stores, it generally follows that after are sh own.

.a time, a hard gummy substance is, deposited within the generator tube at a point, near the burner, or the part of the tube that is sub-' jected to the highest heat, which substance gradually cuts off the flow of the fuel and vapor, thereby rendering the stove less useful if not wholly useless. A filling of longitudinal wires for the generator tube distributes the fuel over a large surface and at the same time gives the most eificient feed for alcohol containing a gummy substance. By'smy improvement, when the generator -tube becomes foul so as to impair the usefulness of the stove, it is only'necessary to withdraw the entire filling from the generator tube and then separate the free ends of the .wires 10 and clean them thoroughly, in anyproper' manner. The flexibility of the wires and leaving their ends free as described, permits of complete separation of the wires 10, so that they may be cleaned one byone, or they will be flexed and rub' one against the other if-the bunch of'wires 10 be rolled back. and forth under pressure. Pulling the wires from the generator tube will break up and loosen the gummy substance that may lie between the Wires and the wall of the said tube, and the cleaner,

scraper, or brush 12, following the said wires, will remove allot the loosened. forelgn matter and also loosen and remove other portions that may not have been loosened in removing the wires.- When thusf D cleaned the filling or cartridge'forthe gener- 35 stove] will be substantially as efficient as ator tube is replaced therein after which the when it was new, and this. cleaning-'canbe repeated as often as may be desired. 1

The construction is simple and inexpensive, and the entire filling may be'removed as a unit.
