INCANDESCENT GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 688,697, dated December 10, 1901- Application filed April 26, 1901.

tles are composed of extremely fragile mate rial, and a slight concussion or shock given the gas-burner will often be imparted to the mantle and cause it to break.

The object of this invention is to provide a sensitive antivibratory support for the mantle, which will protect the latter from the eflects of concussions or shocks to which the lamp may be subjected.

The invention consists in certain constructions, arrangements, and combinations of the parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which- Figure l is a side elevation of an incandescent lamp provided with my improved antivibratory mantle-support, which latter is shown [partly in section. Fig. 2 is a detail side elevation of the float of the said antivibratory mantle-support. Fig. 3 is a bottom plan view of the same. Fig. 4 is a detail top plan view of the cup adapted to receive said Referring to the drawings, the letter adesignatesaburner of the ordinary type, intended to be secured to a gas-bracket. A stationary cup I) is provided with an upward-projecting central tubular socket c, which is fitted tightly over the gas-tube d of said burner and is supported with its lower edge resting on the shutter e of the latter. The central socket 0 forms an annular well f, which surrounds said sooketand is intended to receive a small quantity of metallic mercury g, as indicated in Fig. 1. A tubular float h (shown in detail in Figs. 2 and 8) surrounds the gas-tube d and the socket c of said cup I), and said float is provided at its lower end with an outwardly-extending annular base 2', which rests upon and floats in the mercury g in the said cup. The circular Serial No. 57,562. (No model.)

inner wall j of said base is outwardly and downwardly beveled, as shown in Fig. 1, and at its upper small part Z fits snugly around the socket c and with just suflicient accuracy to permit a free up-and-down movement of the float and to permit only a very slight direct lateral movement of the same, and the lower and larger part m of said inner wall of the base flares away from the socket 0, but surrounds it, all for a purpose hereinafter described.

A jacketo is provided with the usual wiresieve cap 19 and is secured by any suitable means, such as the pin q and bayonet-slot r, to the tubular body portion of the float h. The mantle suspension-rod sis attached to said jacket and extends above the same, and from the upper hooked end zfof said rod is suspended the incandescing mantle to, which preferably extends with its lower end surrounding the said jacket.

One side of the base i of the float his made lighter than the diametrical opposite side to compensate for the weight of the suspensi0nrod 8 upon the light side by cutting away the upper surface of the base i, as shown at 1;; but the invention is not confined to that particular construction, as other expedients to equalize the weight may be used.

It is intended that the cup 19 shall also serve as the support or base for the chimney-gallery, which latter, however, forms no part of the present invention and for this reason is not shown. 85

It is to be especially noted that as the inner wall j of the float-base 2' is beveled, as before described, the mercury g will form an upwardly-tapering cushion between the upwardly-projecting portion of the cup-socket 9s 0 and the said float, and said cushion tapers to almost nothing at the upper edge lot said wall, so that the mercury cushion will allow the float h to slightly oscillate, but will prevent shocks or concussions upon the socket 5, from being imparted to the float. It is also to be noted that by forming the base i with a beveled bottom wall m the float may oscillate without the outer wall of its base coming in contact with the bottom of the cup.

By the construction and arrangement of parts hereinbefore described the mantle is protected from the effects of any shocks or concussions to which the burner may be subjected.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a lamp adapted to use an incandescent mantle, the combination of a stationary cup provided with a well surrounding a gas-tube of the lamp; metallic mercury in said cup; and a tubular float in said cup and adapted to carry or support the mantle, said float being provided with an inclined inner wall surrounding the inner wall of said well, whereby the mercury will form a tapering cushion between said two walls, as set forth.

2. In a lamp of the character described, the combination with a gas-tube of the lamp, of a cup provided with a socket by which it may be inserted over said gas-tube, and also provided with. a well surrounding said socket; metallic mercury in said well; and a float in said mercury adapted to carry or support the mantle, said float being provided with an annular outwardly-,exten din g base having an innor circular wall surrounding said socket, and said inner wall being beveled downwardly and outwardly from said socket, whereby the mercury forms an upwardly-taperin g cushion between said socket and wall.

3. In a lamp of the character described, the combination of a cup, I), provided with a Socket, 0, and well, f; and float, h, provided with an annular base, 2', adapted to float in said cup, and which base has a beveled inner wall, j, and a bottom wall, 1%, beveled upwardly from the lower edge of said inner wall, as set forth.

4. In alamp adapted to use an incandescin g mantle, the combination with a gas-tube of the lamp, of a cup provided with a socket fitting around said gas-tube and said cup also provided with a well surrounding said socket; metallic mercury in said well; and a tubular float in said mercury adapted to support the mantle and having an opening which receives said socket, the wall of said opening and the exterior wall of said socket being arranged with respect to each other so as to form a tapering space between them,whereby the mercury will form a tapering cushion between said two walls.

5. In alamp adapted to use an incandescing' mantle, the combination with a gas-tube of the lamp, of a cup provided with asocket fitting around said gas-tube andalso provided with a well surrounding said socket; metallic mercury in said well; and a float-base in said mercury earryingmeans to supportthemantle and having an opening which receives said socket, said float-base having a greater vertical thickness at the socket-opening than atits outer edge, and said variation in thickness being produced by the conformation of the bottom surface.

6. In a lamp adapted to use an incandescing mantle, the combination with a gas-tube of the lamp, of a cup provided with a socket fitting around said gas-tube and also provided with a well surrounding said socket; metallic mercury in said well; and a float in said mercury adapted to support the mantle and having an opening which receives said socket, said float having an inclined bottom surface whereby the same will have a greater depth in the mercury near the socket-opening than at the outer edge.

In testimony whereof I aflix my signature in the presence of two witnesses.
