BONCI-II LAZARE, OF PORTAGE, PENNSYLVANIA.
MINER S CARBID-LAMP.
Application filed April 26, 1917.
To all whom it may concern:
Be it known that I, RoNoHI LAZARE, a citizen of France, residing at Portage, in the county of Cambria and State of Penns ylvania, have invented certain new and useful Improvements in Miners Carbid- Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in miner s lamps, and the principal object of the invention is to provide a lamp which may be recharged without extinguishing the light.
Another object of the invention is to provide a lamp, which, when the main charge of carbid has been exhausted, is designed to use an auxiliary charge so that the main receptacle may be refilled.
A further object of the invention is to provide a device having two separate water tanks, one of which is mounted above the auxiliary generating chamber, and which is so arranged as to be filled simultaneously with the filling of the main water tank, but from which the water cannot run except into the auxiliary generating chamber.
With these and other objects in view, the invention consists in the novel construction, combination and arrangements of parts which will be fully set forth in the following specification and accompanying drawing, in which:
Figure 1 is a side view in elevation of a lamp constructed in accordance with this invention,
Fig. 2 is a vertical sectional view, taken on the line 22 of Fig. 1,
Fig. 3 is a vertical sectional view at right angles to Fig. 2,
Fig. 1 is a horizontal sectional view on the line 41 of Fig. 2, and
Fig. 5 is a horizontal sectional View on the line 5-5 of Fig. 3.
Referring to the drawing, 1 designates as an entirety the upper section of the lamp, while the numeral 2 designates as an entirety the lower section. The upper section is provided with a threaded sleeve 3, projecting downwardly from its under side, and a threaded neck a projects upwardly from the upper side of the lower section 2 and these threaded sleeves and necks cooperate 1n connecting the two sections together. The up- Specification of Letters Patent.
Patented July 10, 1917.
Serial No. 164,641.
per section 1 comprises a cylindrical wall 5, provided at its upper end with a head 6 and at its lower end with a head 7 to which the collar 3 is secured. A partition wall 8 is soldered through the cylindrical wall 5 at its edges and the lower edge of said partition wall is soldered through the head 7, while the upper edge of the partition wall engages the under side of the head 6. A recess 9 is formed in the upper edge of the partition wall 8 and serves to establish communication between the main and auxiliary Water chambers formed by the wall.
The main water chamber is designated by the character A and the auxiliary water chamber by the character B. A horizontally extending partition wall 11 connects the wall 8 on its concaved side with the cylinder 5 and thus separates the chamber formed beside the main chamber into the auxiliary water chamber B and the auxiliary generating chamber C. It is understood that the wall 11 is soldered, or otherwise secured to the walls 8 and 5, so as to prevent water from leaking into the lower chamber. A filling opening 12 is formed in the cylinder A and arranged to establish communication with the interior of the chamber C, and this opening is closed by a plug 13. A spout 14 is formed on the wall 11 at a point substantially centrally thereof, and serves to allow the liquid contained in the chamber B to flow into the chamber C. A valve 15, which is controlled by the thumb screw 16, is arranged to control the flow of the water through the spout 14, as will be clearly seen upon reference to Fig. 2.
Extending vertically through the center of the cylinder 5 is a tube 17 throughwhich a valve stem 18 rotatably extends. The upper end of the valve stem carries a controlling lever 19, while the lower end of the valve stem is provided with a head 20, which engages the lower edge of the tube 17, so as to control the flow of water therefrom. Connnunicating openings 21 are formed in the tube 17 at a point immediately above the head 7 to allow the water within the chamber A to enter the tube and flow downwardly therethrough into the carbid receptacle 2.
A gas tube 22 is secured in the head 7 and extends upwardly into the chamber A and is bent angularly, as at 28. This gas tube extends through the wall or cylinder 5 and is provided at its outer end with a burner tip 24. It will thus be seen that the gas generated in the interior of the neck 4 passes through the tube 22 and the extension 23 out through the tip 24, where it is ignited. An auxiliary gas tube 25 extends through the wall 8 at a point below the partition wall 11 and projects outwardly and through the side wall 5 immediately below the'tube 23. This tube is also provided with a burner tip 26. A deflector 27 is secured to the upper section 1, in any suitable manner, and is arranged so that the tips 24 and 26 extend through the back wall thereof at a point substantially centrally of the reflector.
It will be apparent from the foregoing that in use the carbid receptacle 2 is first filled with the carbid and the chamber C is also filled with carbid. Water is then poured into the chamber A and it will be seen that the same will gradually fill until the water reaches the level of the recess 9, at which time the same will flow over the wall 8 and into the chamber B. The lever 19 is then manipulated to open the valve 20 and allow the water to flow into the carbid chamber 2, where the contact of the water with the carbid forms acetylene gas which passes up through the tube 22 and tube 23 out through the tip 24, where the same may be ignited. As long as there is unused carbid in the carbid chamber and the Water is fed thereto the air pressure will remain such as to maintain a certain length of flame projecting beyond the pit, but as soon as the carbid becomes exhausted or the waterbecomes low the flame will gradually shorten in length as the pressure is reduced, thus indicating to the user that the lamp should be refilled. In order to avoid the necessity of refilling the lamp in the dark the thumb screw 16 is operated to open the valve 15, which will allow water to flow from the chamber B into the chamber C, and coming in contact with the carbid in the chamber C it will be evident that gas will be generated which will pass through the tube 25 and out of the tip 26, becoming ignited from the flame project ing from the tip 24. In this way it will be seen that the carbid receptacle 2 may be removed and recharged and also water may be poured into the water receptacle, and any inconvenience owing to the lack of light is overcome.
It will be evident that owing to the fact that any communication of the chamber B with the chamber A, below the lower edge of the recess 9, is prevented, even though the water in the chamber A becomes exhausted, there is a sufficient supply in the chamber B to enable the lamp to operate until the chamber A can be filled.
From the foregoing description, taken in connection with the accompanying drawings, the advantage of construction and of the method of operation of the improved miners carbid lamp will be apparent to those skilled in the art to which this invention appertains, and, while in the foregoing description, the principle of the operation of this invention has been described, together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.
What I claim as new is:
1. In a miners lamp, a cylinder, heads closing the opposite ends of the cylinder, a partition wall extending vertically through the cylinder, a horizontal partition wall between one side of the first-mentioned partition wall and the cylinder, a carbid receptacle formed by the horizontal partition wall and the vertical partition wall, a water receptacle formed above the horizontal partition wall and carbid receptacle, said vertical partition wall having an opening in its up per edge, whereby communication is established between the water receptacle and the remainder of the cylinder, a valve controlling the flow of water from the water receptacle into the carbid receptacle, a valve extending through the cylinder for controlling the flow of water therefrom, a main. carbid receptacle adapted to be secured to the under side of the cylinder, burners mounted on the side of the cylinder, and tubes leading to the burners for conducting the gas generated by the mixture of the carbid with the water to said burners.
2. In a miners lamp, a cylinder, heads closing the opposite ends of the cylinder, a vertical partition wall extending between the heads and forming a water chamber on one side of said wall, a horizontal partition wall on the opposite side of the wall forming a carbid chamber and a water chamber above said carbid chamber, the upper edge of the partition wall being provided with an opening to establish communication between the main water chamber and the auxiliary water chamber, a main carbid chamber secured to the cylinder, a valve for controlling the flow of water from the main water chamber to the main carbid chamber, a valve for controlling the flow of water from the auxiliary water chamber to the auxiliary carbid chamber, and burners connected to their respective carbid chambers for consuming the gas generated in said chambers.
In testimony whereof I aflix my signature in presence of two witnesses.
