REGENERATIVE GAS-LAWN.

SPECIFICATIONformi'ng part of Letters Patent No. 343,142, dated June J., 1886.

Application filed May 14, 1885.

To all whom if may concern,.-

Bc it known that we, HENRY E. SooToHMER and JOHN YOUNG, citizens of the United States, and residents of Chicago, county of Cook, and State of Illinois,have invented new and useful Improvements in Regenerative Gas-Lamps, of which the following is a specification, reference being had to the accompanying draw'- ings, illustrating the invention, in which- Figure l is a vertical sectional elevation of a regenerative gas-lamp embodying our invention; Fig. 2, a horizontal plan and section on line zr, Fig. 1, showing particularly the reflector-seat and burner-ring and their position relative to the Argand burner; Fig. 3, a perspective of the burner-ring removed from the other parts better to -show its construction.

he purpose of this invention is to provide simpler and more efficient means for causing a given quantity of illuminating-gas, consumed by what is known as the Argand burner,77 to give an increased light. This is done by an increased or more intense heat, and the object sought is so to utilize air for this purpose by such mechanism as will causel the nearest perfect combustion, and at the same time protect the mechanism from destruction by the increased heat.

The principle of admitting, air by various means termed lamps to flames of gas is known to be old; but the diflieulty of destruc- .tion to the mechanism and the clicking up of the parts by carbon has not so far in the art been sufficiently overcome to insure the public of the practical utility of such lamps. Te claim to have overcome these objections by the following means:

A represents the ordinary Argand burner with its perforated top part for the ordinary escape of gas. Centrally through this burner is placed the gas-supply pipe B,which is made to communicate with the interior of the burner A by means of one or more ordinary branch pipes, C, as shown at Fig. 1.

Placed around the pipe B where it is subjected to the greatest heat, is a cylindrical sleeve, D, of metal, asbestus, or other heat-resisting material, and placed on the supplypipe B, to come about even with the top of the burner A, is a cylindrical seat, E,Which serves the double function of reducing the air-space inside of the b'urner A and furnishing a seat Serial No. 165,515. (No model.)

for the cone F, which is made of some lightcolored heat-resisting material, and somewhat larger than the burner to increase the light and bring the flame into a larger circle before it is drawn into the chimney G'above.

' We do not claim in this application to be the first to use the defiecting-cone above the burner, as the Scotchmer and Bent gas-lamp of Chicago and other lamps have a similar (le- Hector, but differently arranged and combined-as, for instance, our deliector is combined with an adjustable seat, E, which can be held at different altitudes by means of a set-screw, a, and which forms the inner wall of the air-passage on the inside of the burner A, and by raising or lowering it the flame can be more or less abruptly expanded toward the globe H. A deflector, I, is provided with a flange, J, at its bottom to rest on the globestand K, and its top part is a truncated cone to form a suitable-sized air-passage between it and the burner A. It is important that the air-passages which admit air exteriorly and interiorly to the burner should be about the size shown to supply oxygen to both sides of the flame in such quantities as will be consumed thereby, otherwise the llame will blow or become deadened, according to the amount and force of surplus air admitted. To attain this desirable airsupply,care is taken,by means of the flange J on the deilector I, to prevent any air from passing up between the deliector I and globe H, and instead thereof to admit a current of air, as stated, to the inside of the burner, thereby supplying both sides of the flame with air and preventing an imperfect combustion by the admission of air outside ofthe deliector I, as is the case in the patent to Lipsey, May 29, 1883.

L shows an underllame-protector, which is perforated,and is to admit air in proper quantities to the burner by means of the two passages shown and described. It' desirable always to have it in place, it may be hinged to the globe-stand, or it may be held by springclips of ordinary construction to be' readily removable. This is an important construction in that both air-passages to the burner receive their supply of air from a common source, whereby the supply of air through the passages is equalized, inasmuch as the upwardmoving air in a single column is divided in icoquantity, according to the amount required in each passage to support combustion.

The metal chimney-top is shown at G, and exteriorly to it is affixed a housing-support, M, which serves the purpose by extending down into the chimney of forming atight draft-connection. Thechimney-top, by extendingdown into the globe H, causesthe flame from the burner to take an inward direction over the de- {iector F, thereby increasing the heat of the deflector,wherebya nearer perfect combustion is attained and the chimney is made to support the top; but nothing new is claimed for this construction of chimney, but it is employed as best adapted for this lamp.

The globe-stand K is supported by an arm, N, projecting up from a collar, I), which is secured to the lower end of the supply-pipe B by means of a bayonet attachment, R, of ordinary construction.

To remove the globe H, detach the globestand K by disengaging the bayonet attachment R. This will allow the globe H and burner-ring I to be removed downward.

We` claim as our invention and desire to secure by Letters Patentl. In regenerative gas-lamps, the burner A,

deflector F, globe H, gas-pipe, chimney G, globe-stand K, in combination with the protecting perforated plate L, covering the bottom of the lamp, the air-passage between the surrounding plate I and the burner A, and the passages inside the burner which receive air from a common source, for the purpose specitied.

2. The burner A, globe I-I, gas-pipe, chimney G, globe-stand K, perforated protectingplate L, covering the bottom of the lamp, the air-passage between plate I and burner A, and the passage inside of the burner, which passages receive air from a common source through protector L, in combination with the detlector F, and the seat E and pipe B for supporting the deflector and adjusting it to a desired height, as and for the purpose specified.
