COLEMAN T. LYND, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE- IIAIIF TO BELLE M. MILLER, OF SAME PLACE.
DEVICE FOR LIGHTING GAS.
SPECIFICATION forming part of Letters Patent No. 595,023, dated December '7, 1897.
Application filed March 5, 1897. Serial lllox 626,125. (No model) To aZZ whom it may concern:
Be it known that I, COLEMAN T. LYND, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, haveinvented certain new and useful Improvements in Devices for Li ghting Gas; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.
My invention relates to an improved device for lighting gas in that class of burners in which the gas-tip is inclosed within a chimney, shield, or mantle, so that a match or taper cannot be applied directly to the gas-tip, and it is particularly applicable for lighting the well-known YVclsbach burner, in which the gas-tip is surrounded by a mantle that becomes incandescent from the heat of the burning gas inside of it. In this latter class of burners the gas is usually ignited by applying a lighted taper to the top of the chimney after the gas has been turned on, so that the gas which has escaped through the mantle into the chimney is ignited, and the flame being carried downward through the mantle to the gas at the gas-tip the lighting is thereby accomplished. In this case the combination of air and gas within the chimney forms an explosive mixture, so that a slight explosion accompanies the lighting, which has a tendency to injure the delicate structure of the mantle.
My invention consist-s of a diaphragm placed inside of and across the gas-pipe just below the burner, through which diaphragm are two or more small perforations. A lighting-tube has its lower end connected with this diaphragm, so that the passage through it can be brought in line with one of the perforations and thereby supply gas to the lighting-tube at the same time that the unconnected perforations supply gas to the main burner, thereby permitting the gas at the gas-tip to be lighted through the medium of the lightingtube, after which a slight shifting of the lighting-tube disconnects it from the perforation in the diaphragm, thus cutting off the gas from the lighting-tube and permitting the gas which flowed into it through the perforation to pass up into and through the gas-pipe to the main burner.
Referring to the accompanying drawings, Figure 1 is a vertical section showing my invention applied to a lVelsbach burner. Fig. 2 is an enlarged part of the gas-pipe in perspective, showing the diaphragm with its tube connection. Fig. 3 is a vertical section of the same.
LetArepresent the gas-pipe through which the gas is led from the gas-main to the burner.
B is the gas-tip, which is inclosed within the mantle C and chimney D.
E is the burner-cage, upon which the chimney and mantle are supported.
F is the air-supply case, which surrounds the gas-pipe just below the cage E. The gaspipe has openings 2' 2' through it inside this case, and the case has a gage or perforated bottom, through which air enters and is drawn into the gas-pipe to mix with the gas going to the burner in order to make a heating-flame.
In the gas-pipe A, just below the openings 2' 2', I introduce a diaphragm k, which extends entirely across the pipe and plugs the passage. Through this diaphragm I make two or more small holes or perforations 0, through which the gas will pass on its way through the tube to the burner-tip. Upon the upper face of this diaphragm I mount the gas-lighting tube m by means of a swivel-arm n. This swivel-arm has one end pivoted to the upper face of the diaphragm near the side opposite the perforation, While the lower end of a lighting-tube is secured to its opposite or free end, so that when the arm is swung across the face of the diaphragm the lower end of the lighting-tube can either be brought directly over one of the openings 0 in the diaphragm or thrown off, as desired. The lighting-tube is the ordinary small tube with perforations at intervals in its length to carry the flame of the burning gas toward its tip, and it is bent so as to pass out through one of the side openings 2' of the gas-tube A, and thence up to the burner-tip within the cage and mantle, so that its upper end terminates at a point near the tip, where the flame carried upward by it will ignite the gas at the burner-tip.
In passing upward toward the burner-tip, after it passes out of the gas-tube A, the lighting-tube m passes through an opening in the upper portion of the air-case F, and then passes through an opening in the burner-cage E, so that a portion of its length is exposed, and at this exposed point the match or taper can be applied to light the gas.
The air-case F fits loosely around the gastube, so that it can be turned upon it as far as the lighting-tube which passes through the opening in its top will permit, so that by turning this case in one direction the lightingtube is brought into line with the perforation in the diaphragm, and by turning it in an opposite direction the tube is thrown to one side and its lower end thrown out of line with the perforation and the flow of gas into the lighting-tube cut off. This can be accomplished by hand or by means of a gas-lighter.
In lighting the gas at the burner-tip the aircase is first turned so as to bring the lower end of the lighting-tube in line with one of the perforations in the diaphragm, as shown at Fig. 3. The ordinary gas-cock which admits the gas to the burner is then turned on full head. The gas thus admitted into the gas-tube A will be divided, one portion passin g through the perforation in the diaphragm into the lighting-tube, and the other portion, which passes through the other perforations in the diaphragm, going up the gas-tube to the burner-tip. A lighted taper or match is then presented to the lower perforation in the lighting-tube and the gas which issues therefrom is ignited. This flame is then carried upward from this perforation to the successive perforations in the tube until it reaches the top of the tube, where it ignites the gas that issues from the burner-tip. The aircase is then turned so as to cut off the gas from the lighting-tube, and this extinguishes the line of flame that reaches to the burnertip, and the gas which was cut off from the lighting-tube then passes up through the tube A to the burner-tip along with the gas that passes through the other perforations in the diaphragm. By this means the gas inside the mantle or shield is lighted without explosion.
It will be noticed that my lighting device has no connection with the gas-cock that cuts off and admits the gas to the burner, but my device is located in the gas-tube between the gas-cock and the burner.
I am aware that a lighting-tube having a line of perforations in its length for supplying gas to carry a line of flame up the tube is not new, and therefore I do not claim such tube as my invention; but
What I do claim, and desire to secure by Letters Patent, is-
1. A gas-lighting device, consisting of a diaphragm placed across the interior of the gas-pipe, at some point between the ordinary gas-cock and burner, said diaphragm having two or more perforations through it, in combination with a perforated lighting-tube having its lower end adapted to be placed in connection with one of said perforations and to be disconnected therefrom after the gas is lighted, said tube passing out through the gas-pipe below the burner and extending up ward outside the burner so as to terminate at or near the burner-tip, substantially as described.
2. A gas-lighting device consisting of a diaphragm placed across the interior of the gas-pipe at some point between the ordinary gas-cock and the burner having two or more perforations through it; a swivel-arm pivoted to the diaphragm and adapted to have its free end swing over one of said perforations; and a perforated lighting-tube connected at its lower end with the free end of the swivel-arm and adapted to pass through an opening in the gas-tube and thence to the burner-tip, substantially as described.
3. A lighting device for gas-burners, consisting of a diaphragm having two or more gas-passages through it placed across the interior of the gas-pipe, and a lighting-tube connected at its lower end with said diaphragm by a swivel-arm and adapted to swing into line with one of said passages and means for moving the lighting-tube to disconnect it from the passage after the gas is lighted, substantially as described.
In testimony whereof I have hereunto set my hand this 12th day of February, 1897.
COLEMAN T. LYND.
