UNITED STATES PATENT OFFICE.
HAROLD J. BELL, OF GLOUCESTER CITY, NEW JERSEY, ASSIGNOR TO THE WELSBACI-I INOANDESOENT GAS LIGHT COMPANY, OF NEW JERSEY.
SPECIFICATION forming part of Letters Patent No. 400,167, dated March 26, 1889.
Application filed May 10, 1888. Serial No. 273,458. (No model.)
To aZZ whom it may concern.-
Be it known that I, HAROLD J. BELL, a citizen of the United States, residing at Gloucester City, in the county of Camden and State of New Jersey, have invented new and usefullmprovements in Incandescent Gas-Lamps, of which the ollowing is a specification.
The object of my invention is'to provide an improved incandescent gaslamp for use in the WVelsbach system of incandescent illumination.
This invention consists in the construction and combination of parts in an incandescent gas-lamp, as hereinafter set forth.
In the annexed drawings, Figure 1 is a vertical section of an incandescent gas-lamp embodyin g my improvements, and shows a Welsbach mantle or incandescent hood suspended above the burner within an inclosing chimney and globe. Fig. 2 is a plan of the burner. Fig. 3 is a detail sectional view of the burner.
The numeral 1 designates a vertical portion of gas pipe or tube, which forms part of a gas-fixture. This pipe or tube 1 has a shoulder, 2, on which is supported a cupshaped globe-holder, 3, composed of metal, glass, or other material and entirely imperforate, except that it has a central opening that closely surrounds the gas-tube 1 above the shoulder 2. The upper edge or brim of this substantially imperforate globeholder 3 is flanged or recessed at 4 to receive the lower edge of a glass globe, 5, as shown.
The gas-tube 1 is externally screw-threaded above the shoulder 2. for engaging internal screw-threads in the base of an atmospheric gas-tube, 6, which, when screwed into place,
serves to secure the globe-holder 3 in position, though it is obvious that said globe-holder may be otherwise secured.
The atmospheric gas-tube 6 is provided with the usual lateral air-inlets 7, and within said is closed at top and open at its bottom. This bell-shaped shield supports a vertical'y-movable burner-tube, 12, which closely surrounds the atmospheric gas-tube 6, and the lower end of the burner-tube 12 is thus adapted to partially or wholly close the lateral air-inlet 7 of the atmospheric gas-tube 6, according to the vertical adjustment of the supporting-shield. The shield 11 and burner-tube 12 may be formed in separate pieces, as in Fig. 1, or both in one piece, as in Fig. 3, the latter form be ing convenient in affording a means for ad= justing the tube by rotating it from its upper end, which is more accessible than the shield. By reason of the coarse external screw-thread or spiral groove 9 and the spiral ring 10 a slight rotation of the bell-shaped shield 11 suffices to move said shield and burner-tube 12 up or down, as required, to regulate the quantity of air admitted through the lateral inlets. This shield 11, either with or without the imper= forate globe-holder 3, also serves to prevent the disturbing influences of external air-currents.
The vertically-movable burner-tube 12 may be of any suitable construction that is adapted for use in incandescent illumination. In the form of construction shown the burnertube 12 is provided at the top with an enlarged gas and air mixing chamber, 13, inclosing a gauze diaphragm, 14, above which is seated aburner-tip, 15, having a circular series of gas-exits, 16, that open into an annular flame-passage, 1'7, surrounding the unperforated central portion or cone of the tip. This construction, though not essential, is particularly adapted for use in connection with an incandescing device suspended above the burner, as a thorough mixture of gas and air is thereby obtained, and an equable distribution of heat effected within a tubular incandescing device, such as the Welsbach mantle and hood.
Surrounding the burner-tip 15 and upper portion of the burner-tube 12, at a suitable distance, is a deep annular deflector, 18, the lower portion of which is connected by converging ribs or arms 19 to a ring, 20, that is firmly secured around the lower part of the burner-tube. By this construction the burnertube and deflector are practically integral.
As shown, the annular space between the outer wall of the burner-tip 15 and the deflector 18 forms a chamber, 21, to receive and conceal the lower ragged edge of a tubular incandescing device, 22, suspended above the burner. This incandescing device is, preferably, the well-known \Velsbach mantle or hood, composed of refractory earthy material. The man,- tle or hood 22 is suspended by means of a rod or wire, 23,that is adjustable vertically to any required position by supporting the lower part of said rod in a vertically-perforated lug, 24, where it is held by means of a set-screw, 35, in a well-known manner.
011 the outside of the deflector 18 is supported a perforated chimney-gallery, 26, for receiving the lower end of a glass chimney, 27, that surrounds the incandescing device.
It will be seen that in this lamp all. the air admitted to the burner is thoroughly heated before it enters the atmospheric gas-tube 6,
as the impcrforate globe-holder 3 cuts off the the illuminating effects of the incandes- 5 cing mantle are increased, and this result is further promoted by the ascending currents of heated air that pass through the perforated chimney-gallery 26 into the chimney 27, by which the outside of the mantle receives an ample and equablc supply of heat. By slightly rotating the shield 11 to the right or left the said shield, together with the burnertube 1.2, will be adjusted up or down, as the case may be, on the atmospheric gas-tube 6, to control the quantity of heated air admitted to the burner. This shield 11 not only acts as an adjustable support for the burner-tube 12 in controlling the lateral air-inlets 7, but, as will be seen, it also serves as a safeguard to prevent the fiashin g back of the heated gas under the disturbing influences of the outer currents of heated air.
\Vith an incandescent atmosl'iheric gas'lam p of this character, in which the air is heated before entering the burner, a steady, safe, and brilliant light can be economically produced.
I would have it understood that I do not herein claim the particular form of burnertip shown and described, as such is claimed in a application, Serial No. 2613,5015, filed by me March 8, 1888; neither do I herein claim a combined burner and gallery, as such is claimed in application, Serial No. 273,456, filed by me May 1.0, 1888; nor do I herein claim, broadly, the combination of an atmospheric-gas tube having lateral air-inlets, a vertically-adj ustable bell-shaped shield movably supported on the base of said tube and a vertically-ad j ustable burner-tube supported on the shield and movable therewith to cover or uncover the lateral air-inlets, as such is claimed in an application Serial N 273,457, filed by me May 1.0, 1888.
lVhat I claim is 1. In an incandescent atmospheric gas-l amp, the combination of an atmospheric gas'tube having lateral air-inlets, a vertically'adjustable burner-tube surrounding the atmospheric gas-tube and movable thereon to control its air-in lets, an imperforate globe-holder supported beneath the air-inlets of the atmospheric gas-tube, a globe, a gas-burner, and a chimney for said burner, substantially as described.
2. In an incandescent atmospheric ga:-.amp, the combination of an atmospheric gas-tube having lateral air-inlets, a vertically-adjustable bell-shaped shield movable on said tube, a vertical]y-adjustable burner-tube movable with said shield to control the air-inlets of the atmospheric gas-tube, an imperforate globe-holder supported beneath the air-inlets of the atmospheric gas-tube, a globe, a gasburner, an annular deflector surrounding said burner, a perforated chimney gallery, a glass chimney, and an incandescing device suspended within said chimney above the burner, substantially as described.
3. In an incandescent atmospheric gasamp, the combination of an atmospheric gas-tnbe having lateral air-inlets, an imp erforate glob eholder supported beneath said air-inlets, a shield supported on the atmospheric gas-tube and surrounding the lateral air-inlets to pre vent the flashing back of gas, and means for controlling the quantity of air admitted through said. air-inlets, substantially as de scribed.
In testimony whereof I aiiix my signature in presence of two witnesses.
HAROLD J. HELL.
