ACETYLENE-LAMP.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed July 14, 1915. Serial No. 39,881.

To all whom it may concern Be it known that I, JAMEs Bnocnnn, a citizen of the United States, residing at the city of Collinsville, Madison county, Illinois, have invented a new and useful AcetyleneLamp, of which the following is a specification.

This invention relates to improvements in acetylene lamps, and more particularly to that type of acetylene lamps using gas generated by a mixture of chemicals effective for the production of gaseous fuel, for instance acetylene gas generated from the mixture of carbid and water. I

An object of the invention is to improve the construction of acetylene lamps of the type described with provision of a simple, unitary structure including duplicate burners and independent gas generating means, so that if one means for generating the gas becomes disabled, the other may be utilized under such emergency for the purpose of illumination.

To the foregoing end as well as the attainment of the specific advantages which will be apparent to those skilled in the art from the following detailed disclosure without specific mention I have designed and arranged the structure clearly illustrated in the drawing to which reference is made and in which:

Figure 1 is a plan view of an acetylene lamp including the present invention.

Fig. 2 is a side elevation of the lamp, further illustrating the construction: and,

Fig. 3 is a vertical section through the lam taken substantially on the line 3-3 of Fig. 1.

In the embodiment of the invention illustrated in the drawings the lamp is shown as including a container A comprising a side wall 1, a bottom wall 2 and a top 3, preferably formed integrally and from spun metal sheeting. A hook 4 or other suitable device is attached to the side wall 1 for the purpose of removably mounting the lamp in position in the usual manner upon a can or other suitable support.

The container A is divided into two compartments B and C respectively, by a cylindrical wall 5 fitted within the container A. Through the top wall 3 and over the compartment B of the container A is an opening 6 which is embraced by an lip-standing annular flange 7. A cup-shaped cap 8 provided with a. horizontal flange 9 is pivoted upon the top wall 3, the pivot connection including a bracket 10 and a strap 11. This construction provides a movable closure for the opening 6 and, as the parts are secured together by the pivot connection, the closure is always maintained in position, so that. access to the compartment B may be attained for the introduction of water or other fluid into the compartment and the closure readily replaced after the chamber has been filled. in order to permit the flow of the fluid from the compartment B and to prevent the forming of a vacuum in the upper part of the compartment a perforation 12 is provided in the closure.

Through the top wall 3 above the compartment C is an opening 13 which. is embraced by an outwardly extending annular flange 1%. The upper part of the wall 5 is bent to form threads 15 and is adapted to receive in threaded engagement the side wall 16 of a compartment D. 1

The compartment D includes the side wall 16, a bottom wall 17 and a top wall 18 formed preferablv in integral construction from spun sheet metal, and forms'a separate container adapted to receive a fluid. An opening 19 in the top wall 18 provides means of access to the compartment D and is embraced by an Lip-standing flange 20 adapted to receive a pivoted closure 21, similar in construction and mounted in a similar manneras is the closure 8.

In order to form a hermetic seal of the joint between the upper portion of the wall 5 and the wall 16 of the compartment D a rubber washer or gasket 22 is interposed between the inner surface of the flange 14 and the shoulder 23 formed around the wall 16 adjacent to the top plate 18.

A tube 24 extends through and is formed integral with the compartment D, the upper end thereof extending above the top wall 18 and the lower end extending for a distance below the bottom wall 17. The lower end of the tube 24 is provided with a conical port 25 which is adapted to constitute a seat for a conical valve plug 26 mounted upon a stem 27. The stem 27 is provided with a threaded enlargement 28 which cooperates with a threaded portion 29 of the upper end of the tube 24'. The stem 27 is bent at 30 providing a finger piece whereby the stem may be rotated to raise and lower the valve plug 26 from its seat 25.

Through the walls of the tube 24 adja-icent to the inner face ofthe bottom wall 17 are provided perforations 31 constituting ports for the passageof fluidcontained in the compartment D into the tube. It will into the compartment C upon the carbid conta ned in the bottom oi said compart- -ment, gas will be generated WllTCl] will pass outwardly through a tube 32, the outer end of which is equipped with a jet tip 33.

Within the tube 32 it is preferred to pro vide a quantity 34 of fibrous material, for

instance cotton. to prevent the excessive passage of gas to the tip 33.

The containers C and D with the associated parts constitute an independent gas generating means for the supply of gaseous fuel for the tip 33. 7

In order to prevent the passage 25 from becoming choked by an accumulation of carbid or other chemical that might be used, the lower end of the stem 27 is provided with a polygonal projection 35 so that, when the stem 27 is raised in the tube, the edges or the polygonal projection will come in contact With the edges of the opening 25 and thereby remove the accumulations thereon.

Extending downwardly from the bottom wall 2 of the container A is a tubular eXtension 36, the walls of which are bent to form threads. A container E comprising an annular sidewall 37, a bottom wall 38 and a top wall includingan inclined portion 39 and a tubular neck 40 is adapted to be removably secured in association with the container A. The tubular neck 40 is bent to form threads adapted to be received in threaded engagement with the extension 36.

In order to provide a hermetic seal or joint between theextension 3.6 and the compartment E a rubber washer or gasket 41 is mounted upon the portion 39 of the con tainer E and is adapted to be embraced between said lnclined wall portion 39 and au' outwardly-flaring and downwardly-extending flange 43 formed at the bottom of the tubular extension 36.

A tube 43 is mounted within and into grally formed with the compartment B and extends'upwardly through the top wall 3, the upper portion thereof being threaded to receive an enlarged threaded portion 44 of a stem 45 which is adapted to-be manipulated by a finger piece 46 formed at the top'ot said stem. The stem 45 extends throughout the length of the tube 43 which terminates; within the chamber E, sa-id'stem 45 carrying a conical valve plug 47 adapt ed to cooperate with a passage 48 constituting a valve seat'therefor in the bottom of the tube 43.

The valve is operated similarly to the operation of the valve 2526 as heretofore described. "The stem 43 includes, as does the stem 27, a polygonal portion 49 for the purpose of removing accumulations upon the edges of the valve seat 18. The tube 43 has perforations 50 through the wall thereof within the compartmentB constituting passage ways for the liquid, from the compartment into the tube, which is delivered through the valve 4748 to the com artment E where it comes in contact with the chemical contained in said compartment generating gas in the manner understood and as hercinbefore described.

A tubular extension 51 is provided with a jet tip 52 affording means for conducting the gas enerated in the compartment E to a point for consumption. A piece of fibrous material 53, which is deflected downwardl over the opening between the tubular portion 51 and the opening in the extension 36, provides a porous wall preventing the excessive passage of the gas from the jet 52.

It will hev noted that the jets 33 and 52 are in vertical alinement so that the flame from the one maybe transferred to the other by fanning the flame with the hand, or in ny suitable manner, the jets being arranged sufficiently close to each other to permit ignition of the one jet from the other'in this manner. V

A reflector 54 provided with openings embraced by inwardly extending flanges 55 and 56, respectively, is adapted to befitted in position to serve both jets, the flanges 55 and 56 engaging over the ends of the tubes 32 and 51 respectivel 7 This construction permits the reflector to be removed or adjusted in position with facility.

I am aware that modifications in the details of construction -mav be made without departing from the spirit and scope of the invention. I do not'desire to limit myself, therefore,,t o the exact details shown and described, but what I claim and desire to secure by Letters Patent is 1.
