SAMUEL F. HODGES AND WILLIAM H. LEE, OF NOCONA, TEXAS.

APPARATUS FOR GENERATING ACETYLENE GAS.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Application filed January 20, 1910. Serial No. 539,063.

To all whom it may concern:

Be it known that we, SAMUEL F. Honors and VVLLLIAM H. LEE, citizens-of the United States, residing at Nocona, in the county of Montague and State of Texas, have invented certain new and useful Improvements in Apparatus for Generating Acetylene (Jras, of which the following is a specification.

Our invention has relation to improvements in an apparatus for generating acetylene gas applicable to general purposes, and it has for its object to provide suitable means for carrying out said improvements for the purposes intended. And it also has for its object to provide a generator that will feed the water into the carbid from the main reservoir instead of having a separate one. And it has also a further object to improve, simplify and minimize the cost of construction of this class of device over the existing prior state of the art.

WVith these and other objects in view the invention consists in the novel construction and combination of parts as will be hereinafter more in detail described and the asserted novelty specifically claimed.

WVe have fully and clearly illustrated our invention and the mechanism by whlch the objects hereinbefore stated are attained, in the accompanying drawings in which;

Figure 1 is a vertical longitudinal section. Fig. 2 is a vertical section at right angles to Fig. 3, and Fig. 3 is a detail view of modification of the closure.

Similar letters of reference indicate similar parts throughout the several figures of the drawings.

A designates a water reservoir of the usual or ordinary construction.

B designates a movable gas holder which telescopes within the reservoir A and is movable upwardly and downwardly therein to within a short distance from the bottom of the reservoir.

G designates an annulus to the periphery of which is secured at predetermined and suitable distances apart one end of each of four short braces D, D, D, D, the opposite end of these braces being secured to the inner walls of the gas holder as clearly shown in Figs. 1 and 2 of the drawings. These braces form a firm support for the centrally located annulus which as the gas holder moves up or down in the reservoir the annulus is carried by the same and strikes the lever of a water valve which will be hereafter explained.

E designates a generator, in this example one only is shown, but if desired it is proposed to use two, said generator forming an integral part of the reservoir A and located in the bottom of said reservoir, the forward or open end of which is provided with a screw-cap E for opening and closing the same, but if preferred another form of closure is shown in Fig. 3 which is a circular disk or head F provided with a gasket interposed between the peripheries of both the disk and the end of the generator. If the latter construction is preferred the end of the generator is opened and closed by means of a thumb screw E being applied to the disk.

G designates a carbid drawer divided. off into separate compartments by means of a multiple number of partitions g, eleven of which are herein shown, the upper portions of which have V-sha-ped notches out therein to allow the water from the reservoir to more freely enter the drawer, the partitions being secured in said drawer at predetermined distances apart.

H designates a valve or cock, the lower end of which is projected through an opening H formed in the periphery of the forward and open end of the generator, said cock being controlled by means of a handwheel H I designates a water pipe centrally disposed in the reservoir and composed of a horizontal and vertical section united by means of a union I, the outer end of the horizontal section being projected within an opening in the casing of the valve or cook and its inner end united to the lower end of the vertical section by said union I forming a connection therewith for the water supply to the carbid in the carbid drawer.

J designates a water valve lever pivotally and operatively secured to the vertical portion of the pipe I at j.

K designates a water-feed valve secured to the underside of the larger and looped end of the valve lever J.

L designates a coil spring, the lower end of which is secured midway the length of a short and transversely arranged pin Z which is passed through a perforation Z in the valve lever, its opposite end being passed over a small hook Z secured to the pipe I near its upper end.

M designates a small curvilinear pipe having one of its ends secured to the lower end of the vertical section of the pipe I, its opposite end being free to be controlled by the valve K of the water valve lever. If preferred the valve' K may be operated by a weight secured to the water valve lever.

N designates a hollow drier stuffed with cotton and secured to the upper end of the water reservoir by means of the ends of a metallic strap or any suitable fastening means, a short tubular opening being centrally secured or formed integrally with the upper head of the drier for the purpose of allowing the gas to escape from the gas holder or dome and allow the same to descend.

O designates a short horizontal pipe or elbow which secures detachably together the lower end of a long vertical pipe 0 and a short tube projected centrally from the lower head of the drier, this pipe and tube serving to conduct the gas from the holder into and out of the drier.

From the foregoing description taken in connection with the accompanying drawings the operation of our device will be obvious,

but may be briefly rehearsed as follows:

The drawer of the generator being previously filled with carbid the. gas holder then moves up and down in the water reservoir, and when in its descent it reaches a short distance from the bottom of the reservoir the annulus within the holder or dome strikes the lever of the water valve, causing the same to open, allowing the water to pass through the water pipe into the carbid retainer when the water contacts with the carbid, gas is generated and it passes through the same pipe into the dome or holder causing the same to rise and allowing the water valve to close. In consequence of the several partitions in the carbid retainer the water cannot come in contact with too much carbid at a time, if such should be the case it would cause too much gas to be generated at a time. WVhen one of the divisions in the carbid retainer becomes exhausted the water will then overflow through a notch or open- 111g in the top of the partition to the adjoining one and so on to the last one. The gas passes out of the holder or dome through the drier and allows the holder or dome to descend. hen we wish to combine two generators into one so that one may be held in reserve while the other is being used it has this advantage, if the one being used only should become exhausted at night, by closing the angle valve on this one and opening the angle valve on the other the apparatus will continue to generate gas without having to fill the carbid retainer at night. The object is to provide a generator that will feed the water into the carbid from the main water reservoir, instead of having a separate water. reservoir. The generator is passed horizontally through the water thereby keeping it cool while gas is being generated.

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

In an apparatus for generating acetylene gas the combination with the reservoir, gas holder, and generator with the annulus constructed as herein shown and described, and located centrally within said holder, and braces for securing the annulus to the inner walls of the same, and the periphery of the annulus, a water and gas pipe formed with a vertical and horizontal section, a union uniting said sections, a short curvilinear pipe secured to and projected from the lower end of the vertical section, a cock secured to the forward end of the generator for regulating the flow of water from the reservoir to the gas generator, a water. valve lever looped about'and pivoted on said water and gas pipe, a valve secured to the underside of the lever, a coiled spring connecting the valve lever and the vertical section of water and gas pipe, all constructed, arranged and operating substantially as and .for the purposes set forth.

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