UNITED srarns, PATENT onruon AUGIE L. HANSEN, or cHIcAeoILLINoIs, ASSIGNORTO JUSTRITE MANUFACTURING COMBANY, OF CHICAGO, ILLINOIS, A CORPORATION OF IL-Lmors.
J ACETYLENE-LAMP.
Application filedMarch 30,1914. Serial No. 828,112.
To all whom it may concern:
Be it known that I, AUGIE L. HANSEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Acetylene-Lamp, of which the following is a specification.
My invention relates to acetylene lamps and particularly to those used by miners.
Lamps of this character with which I am familiar are usually formed of sheet metal and are generally soldered together. These lamps are generally used on miners caps, and it sometimes happens that the miner strikes the lamp against the wall of the mine and the seams open permitting the escape of gas into the mine if it is the carbid receptacle which is damaged, or permits the water to escape if it is the water reservoir, each of which is disastrous inasmuch as it deprives the miner of light.
In addition to this, these lamps are generally drawn or spun which is an expensive method of manufacture, and it is well known that there is no way of drawing sheet metal so as to insure a uniform thickness of wall throughout the article.
My invention has for its object to avoid the danger of a lamp being opened at its seams and to provide a construction which will be very much more inexpensive than the making of a lamp from sheet metal and consists of constructing an absolutely seamless lamp.
My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which:
Figure 1 is a vertical sectional view of my improved lamp.
Fig. 2 is a cross section taken on line mm in Fig. 1.
Fig. 3 is an enlarged fragmentary detail View showing the gasket for making the joint gas tight intermediate the carbid receptacle and the water reservoir.
Similar reference numerals refer to similar parts throughout the entire description.
As shown in the drawings, my lamp comprises a water reservoir 1, which is cast without a seam, one end 52, forming the reflector, a passage 3, through which the gas passes from the carbid receptacle to the Specification of Letters Patent. Patented J 119 26, 1917 burner is cast integral with the walls of the reservoir, the opening in the reflector being adapted to receive the burner tip 4. A boss 5, is cast in the bottom of the reservoir and has threads cut therein which are adapted to be engaged by threads cuton the upper end of a rod or stud 6, which is cast or formed in the center of the carbid receptacle 7. This boss may, if desired, be formed of a separate piece of metal and screwed or otherwise secured to the wall of the water reservoir. This receptacle is also cast Without a seam. The result of this construction is that when the two are joined together, they present a lamp which is absolutely seamless and which can be made very inexpensively.
A filler opening 8, and valve opening 9, can be cast in the water reservoir of desired size or shape for the purpose they are intended for.
Although I have shown and described a specific form for this lamp, it will be appar ent to persons skilled in the art, that my invention is not limited to any particular form, but is only limited as such limitations shall appear hereinafter.
Having described my invention what I regard as new and desire to obtain by Letters Patent is:
1. A miners lamp comprising the combination with a water reservoir having its side and end walls cast integral, of a carbid receptacle having its side and bottom walls cast integral, the front wall of the water reservoir being concaved to form a reflector, a central rod integral with the carbid receptacle, the upper end of said rod being threaded, a boss cast in the bottom of the reservoir and having threads cut therein to cooperate with the threads of the central rod of the carbid receptacle, whereby rotation of the water receptacle will hold the water reservoir and carbid receptacle in engagement with each other, and means for providing communication between the water reservoir and carbid receptacle.
2. A miners lamp comprising the combination with a water reservoir having its side and end walls cast integral, of a carbid receptacle having its side and bottom walls cast integral, a reflector forming the front Wall of the Water reservoir, the water reservoir having a depending annular flange for engaging the upper :edge :of the tcarbid recation between the water'receptacle and carceptacle, a threaded rod carried by the carbid receptacle. 10 bid receptacle, a threaded boss carried by the In testimony whereof I have signed the Water reservoir for cooperating with the foregoing specification.
