INGANDESCENT GAS-LAMP.
Specification of Letters Patent.
Patented July 2, 1912.
Original application filed July 15, 1910, Serial No. 572,190. Divided and this application filed August 19,
To all whom it may concern:
Be it known that I, THOMAS J. LITLE, J r., resident of Woodbury, Gloucester county, New Jersey, have invented a new and useful Incandescent GasLamp, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is an elevation of a lamp embodying my invention; Fig. 2 is a vertical section of the same; Fig. 3 is a top plan view; and Fig. 4 is a detail view showing the valve actuating devices.
My invention has relation to incandescent gas lamps, and more particularly to lamps of the manifold inverted type.
The invention is designed to provide a novel construction and arrangement of the gas and air mixing devices, whereby a largely increased efliciency is obtained.
The invention also provides means of novel character for centering the gas jet tube with reference to the mixer tube; also a novel arrangement of air regulating device or shutter, which is operated in conjunction with the gas valve to give a rich mixture of gas in lighting the lamp, thereby preventing flash-backs, and also giving a rich mixture when the valve is closed, thus preventing explosions in the manifold chamber which would injure the mantles.
Other objects of my invention and novel features thereof will hereinafter appear.
Referring to the accompanying drawings, the numeral 2 designates the casing of the lamp, which is provided with the vertical chimney portion 3, forming an extension of the lower chimney section 4 which is secured within the lower portion of the casing. This casing may be of any desired ornamental form. It is shown as having outwardly flared upper and lower portions 2 and 2 which are suitably beaded and ornamented.
5 designates the globe-holding ring, which is secured to the lower portion of the casing in any suitable manner, such as indicated at 7 and 8. The globe holder, however, and the means of securing the same, form no part of the present invention.
9 designates the globe. v
10 is the gas supply pipe having a vertical arm which leads centrally to the top of the chimney 3 into the upper portion of which Serial No. 644,926.
it extends, and is then bent outwardly as shown at 10", and extends radially across the chimney and through a slot or opening in the upper edge portion of the same. It is then carried downwardly as shown at 10 through a slot 11 in the casing portion 2 The lower end of the portion 10 is connected to a valve casing 12.
13 is a valve spindle, carrying a suitable valve 14 within said casing.
15 is the gas jet tube, which is connected to the outlet of the valve chamber, and which extends into the upper end of the mixing tube 16.
The valve stem 13 has rigidly secured to it a ratchet 17, which is arranged to be operated by the pawl end 18 of an actuating lever 19. This actuating lever has a loose pivotal connection at 20 with a plate 21, which is loosely mounted on the valve spindle, and which is provided with a projection 22 extending loosely through a slot 23 in the actuating arm of the lever 19. A spring 24 is coiled around the end portion of the spindle, one end of this spring engaging the projection 22, as shown at 25, and the other end extending over a pin or arbor 26, and terminating adjacent to the periphery of the ratchet 17 to engage the teeth thereof and form a stop for holding the ratchet against back movement after it has been actuated. The plate 21 has a projecting stop arm 27, which is arranged to engage the pin or arbor 26, and limit the upward movement of the lever 19; and also has another projecting arm 28, which is de signed to engage one arm of a lever 29 (as best seen in Fig. 1), which is pivoted at 30 'to the valveoasing. The other arm of this lever is engaged with the bent arm 31 of an air shutter device 32, which is arranged to reciprocate within the upper open end of the mixing tube 16.
The lever 19 is normally held in its upward position, shown in Figs. 1 and 4, by the tension of the spring 24. The valve being closed, a downward movement of said lever causes its pawl to engage the ratchet 17 and thus rotate the valve stem sufficiently to open the valve. At the same time the leverengages the arm of the lever 29 and raises the shutter 32 so as to partially close the entrance of air to the mixer tube, thus giving a rich mixture in starting, which prevents flash-backs. AS soon as the lever is released, the spring returns it to its former position; the end of the spring 24 engages a tooth of the ratchet and holds the valve in its open position, and the projection 28 of the plate 21 engages the under side of the lever 29 to insure the movement of the shutter back to its normal lowered position, and to hold it in such posit-ion. The next operation of the lever will operate the ratchet another step to close the valve, the shutter being again raised, giving a rich mixture to prevent explosion in the manifold. The end of the valve stem is preferably provided with a double pointer 33, which by its position will indicate whether the valve is open or closed.
For the purpose of adjusting the normal position of the shutter to control the amount of air entering the mixing tube, I provide the adjusting screw 34, which engages the bent arm 31 of the shutter and thereby determines its normal lowered position with respect to the upper end of the mixing tube.
It is of considerable importance that the endof the gas supply or jet tube shall be directed axially into the mixer tube and properly centered, so as to entrain the proper amount of air. For this purpose, I form said tube in two parts, the upper part designated at 15 having a threaded bearing in its outer end for the usual needle valve 35, and the lower end portion having a flange 15 which is arranged to seat against the outwardly turned and overhung end 16 of the mixer tube. This outwardly turned 7 and overhung end has a perforation to receive a boss or projection 15 of the upper section 15 of the jet tube, and which projection is exteriorly threaded. The lower member 15*- of the tube, which has an orifice therein for the point of the needle valve, is in the form of a nut, having an internal thread to engage the externally threaded boss 15". By thisconstruction the jet tube may be accurately centered with respect to the mixing tube.
The mixing tube extends obliquely downward and inward through an opening in the side of the chimney portion 3 of the casing,
being of gradually enlarging cross-sectional area toward its lower end, which opens into and carries the centrally located manifold 36. The increasing area of the mixing tube toward its lower end provides for the expansion of gas and air as it becomes heated, and has been found to very greatly increase the efficiency of the lamp.
37 designates burner tubes, of which any desired number may 'be employed, and which are connected to the manifold. The manifold 36 is provided with an interior chamber 36 of suificient area to provide'for thoroughly mixing of the gas and air before it passes to the burner tubes.
38 designate the usual mantles of the inverted type.
39 designates an impedance cartridge which is adapted to'be placed across the tube may be arranged as shown to form one' arm of a spider,having other radial arms t? (see Fig. 3), which support the chimney, the arm 10 of the supply tube having a flange 48 which is firmly secured by screws or other means to the chimney.
49 designates a pilot light supplied by the tube 50 having the regulating screw 51.
My invention provides means of simple and effective character for efiecting the proper mixture of air and gas, and for giving a rich mixture of gas in lighting the lamp, whereby flash-backs are avoided.
It will be obvious that various changes may be made in the details of construction and arrangement of the parts without departing from the spirit and scope of my invention as defined in the appended claims.
This application is a division of my pending application Serial No. 572,190, filed July 15th, 1910.
