CARBURETlNG-LAM P.

SPECIFICATION forming part of Letters Patent No. 395,834, dated January 8, 1889.

Application filed October 13, 1886.

To all whom it may concern.-

Be it known that we, ARTHUR KI'rsON and WILLIAM SMITH HOBBY, both of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Carbureting-Lamps, of which the following is a specification.

Our invention has reference to gas-fixtures; and it consists in certain improvements, all IQ of which are fully set forth in the following specification, and shown in the accompanying drawings, which form part'thereof. Heretofore gas-fixtures of this class have been made with an extensive heater for the incoming gas arranged above the flame, which heater and gas-pipe were exposed to the atmosphere on all sides and the carbureting-receptacle was located below the gas-burners and detachable, leaving the burners as part of the suspended fixture. It has also been proposed to provide a gas-fixture with a central heaterpipe having a surrounding case and a carbureting-receptacle above the burners and heated thereby. It has also been proposed to 2 5 suspend shades by means of expansible clamps, but not in connection with a gas-fixture of the nature hereinafter set out.

Our invention has particular reference to a form of fixture set out in our application,

Serial No. 202,598, filed May 19, 1886, in

which a central gas-pipe is divided longitudi nally into spiral passages and surrounded by a heat-arresting case, which, while it heats the gas to a constant degree, prevents overheating. In that application the said construction is embodied with the employment of a carbureting-receptacle at the bottom of the gas-supply .pipe and below the gas-burners. This application is an improvement thereon in the following respects-viz., the carbureting or enriching receptacle is made with the burners rigidly secured to it, whereby, whenever the receptacle is removed for replenishing, the burners must be removed also, and thus their inspection is naturally insured. Gas-burn ers in fixtures of this class have a tendency to become clogged by the deposition of the carbonaceous deposits from the enriched gas, and it is of the utmost im- I serial No. 216,127. (No model.)

portance to provide means for the proper inspeotion of said burnersa work which cannot be properly done when the burners are made part of the rigid fixture, as has heretofore been the case. The construction may also be simplified by making the burners rigid with the carbureting-vessel. The construction of the heater-case for arresting the products of combustion is extremely simple, and yet most desirable and ornamental. The gas-regulating valve is arranged at the top of the gas-pipe and protected from heat by an extended shield, which also protects the gaspipe above the valve from ascending heated products, preventing it acting as a heater in any manner. The shade is held to the fixture by a removable jointed clamp, which encircles the heater-case, and hence may be readily applied to fixtures already erected, and may be adjusted high or low, as desired.

The foregoing improvements enable the fixture to be used with the best effect and with the least care, is cheap to construct, durable in use, not liableto get out of order, and is highly ornamental in appearance.

In the drawings, Figure 1 is a sectional elevation of a gas-fixture embodying our invention. Fig. 2 is a plan view of the burners I and carb ureting-receptacle removed from the gas-pipe, and Fig. 3 is a perspective view of the adjustable and removable shade-clamp.

A is the central gas-supply pipe, and is connected at the top to the gas-main section B by a valve, C, having an operating-lever, c. This gas-pipe A is preferably provided with a spiral or twisted ribbon of metal, a, to cause the gas to be divided and insure its being thoroughly circulated and mixed, whereby it is all uniformly heated to a fixed degree.

Surrounding the pipeA at the top and resting against the valve C is a large washer, M, 0 which receives the large circular shield L, the outer part, Z, flaring upward and throwing off any ascending products of combustion or heated air and keeping the gas-pipe above the shield cool. The lower part of this shield re- 5 ceives the upper end of the case K, which forms an annular space, It, around the gaspipe, the top of which is practically or simultaneously closed. The small leakage at the joint on, or from one or more very small holes, N, in the top of the casing, would be advantageous in very slowly and gradually causing a change in the heated products in the space 7.". The lower end of the case K is centered and held up by hell 0, which is preferably of much less diameter than the shield ll. This bell has a shoulder, 0, which receives the case K and keeps it in place. The upper part of the bell fits snugly around the pipe A, and is perforated, as at o, to allow ingress to the heated products ascending from the burners. This bell is held up in place by a sleeve, '1, which surrounds the pipe A, and which is clamped upward against said hell by the nut l) of the coupling for connecting the burners and caldmretingwcssel to the gas-pipe A. It will now be observed that the fixture from I to D is all rigidly clamped together by valve C and nut l), and yet it may be dismantled when desired for repairs. This portion of the fixture secured to the building by a permanent joint. y

The carlmreting-vessel II is made of light sheet metal spun into shape and permanently secured to the coupling-sleeve E. Screwed into the sides of this piece E and close to the carburetor are the gas-burner pipes G, which radiate from the center and are provided with the burner-tips g. From this it will be seen that there is one large central opening, F, and a series of small lnn-ner-openings from the carburetor. This combined carburetor and burner is detachably secured by the couplingjoint e with the nut I), and the joint is made gas-tight by a packing-washer, d.

J is a small end section of pipe, which may be screwed into the bottom of the gas-pipe A and project through the opening 11 into the carburetor, as shown.

By thus making the carburetor rigid with the burners both must be removed together, thereby enabling the burners to be thoroughly inspected and cleaned every time it is required to replenish the carburetor with the carbureting material, which is in practice a crystallized carbon of high volatility. Considerable dit'ficulty has been experienced in attaching shade or shades to fixtures of this class. In some instances shades are not desirable or wanted; but heretofore it has been necessary to secure the holder for the shade rigidly on the fixture, whether the shade was required or not, as otherwise, it a shade were required, the entire fixture would have to be taken apart to put on theholder. In the present construction the globe-holder P is made of two parts, P, hinged together at p and clamped upon the case K by a thumbscrew, 1), which draws the parts P together. These parts of the clamp have the hooked arms I, which fit into the annular groove 8 of the shade or globe S and support it. By this construction the shade maybe readily adjusted high or low, as desired. This clamp may be modified in many ways, the detail thereof being immaterial to our invention, as the essential feature is an adjustable clamp with a fiXtu re of this class, whereby the shade and its clamp may be put on or taken off a fixture when in use. The shade is of such a shape and diameter that it collects and directs the products of combustion up between the annular space-formed by the arms of the clamp and shade around the case K to pro tect it against cold-air currents. The form of coupling between the pipe A and carlmretor may also be modified; hence while we prefer the construction shown the details thereof may be varied without de iarting from ourinvention.

\Ve do not herein claim the subject-matter claimed in our applicaticm, Serial No. 202,598, tiled May 19, lSSb'.
