GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 694,287, dated February 25, 1902. Application filed July 23,1901. Serial No. 69,400. on model.)

To aZZ 1072 0121, it burg concern.-

Be it known that I, PETER KRIEs, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have in vented certain new and useful Improvements in Gas- Burners, of which the following is a specification. 4

My present invention pertains-to improvements in gas-burners, the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein Figure 1 is a side elevation, partly in section, of the burner; Fig. 2, a transverse sectional View on the line 1 1 of Fig. 1; Fig. 3, a plan view illustrating one position of the burner, the mantle-support, and mantle; and

Fig. 4;, a similar view illustrative of the action of the parts under lateral deflection.

As is well known to those conversant with the practical use of incandescent mantles the life thereof is materially shortened and at times the mantle entirely destroyed by being subjected to jars or vibrations, which of necessity it will meet with in various positions. 'The fragility of the mantles precludes their use to a greater or less extent in many places-such, for instance, as in portable burners. When used for street-lighting, the mantles will often break, the breakage being due to the vibrations incident to the passing of heavy trucks,cars, or the like.

The object of this invention is 'to provide a simple and effective means for so supporting the mantle as to relieve it from practically all jar or vibration, and as a consequence to materially lengthen its effective life. With this end in View I provide a structure wherein the mantle is held in a balanced position over the burner or gas-supply tube, so that the burner or tube may move up or down or sidewisein any direction without imparting its motion to I tip freely in any direction one independent the mantle.

In practical use the mantle may move slightly; but the motion, if there be any at all, will be so slight andso gradual and gentle that the mantle is not aifected injuriously.

Referring tothe drawings, A designates the base or body of the burner, B the gas-supply tube extending upwardly therefrom, and O the usual gallery or chimney support. These ;parts may be of any type, those shown being theordinarycommercialform. Surrounding the upper port-ion of the gas-supply tube Bis a second tube or sleeve 'D, carrying at its upper end a gauze or foraminous cap or cover E and forming the usual Bunsen burner. Member D is of such internal diameter that it may move freely up and down with reference to tube B, and said parts may have a relative movement from their normal vertical alinementthat is to say, one may be rocked or tilted sidewise without of necessity moving the other part. Tube or sleeve D carries the mantle-support F, from which is suspended the mantle G. Connected to the body of the tube or sleeve are arms H, by preference three in number, the arms extending downwardly and outwardly from the tube. A series of levers are fulcrumed on the gallery, the inner end I of each lever being connected to the lower end of the correspondingarm' H byalink J. The

outer end K of each lever is screw-threaded and has mounted thereonaweight L. In the construction illustrated a ring or wire M forms the pivotal support for all the levers, the ring resting against the inner face of the galleryand soldered thereto, if so desired. The gallery is cut away or slotted to permit the levers to pass therethrough, as will be readily understood.

The parts are so proportioned and arranged that the outer ends of the levers will stand in the position indicated in Fig. 1, wherein it will be noted that the outerends of the levers stand just to one side of the vertical, and this is brought about by the form given to the levers and also the adjustment of the weights to counterbalance the tube or sleeve D and the mantle.

As above noted, it is preferred to employ three levers, and these should be equidistanitly spaced around the burner. By so doing the sleeve D or the tube B may rock or of the other when a force is exerted thereon, and yet come back to its proper position immediately the cause of movement is removed. This is illustrated in Fig. 4. So, too, the parts may move up or down relatively and be brought back to their normal position by the weighted levers. The tube or sleeve D is shown in a depressed position in Fig. 3. It will of course be understood that the parts ICO may partake of motion which is both lateral and up or down, the connections shown permitting this and at all times acting to bring the parts back to their normal positions.

If necessary, the lower end of the tube or sleeve D may be weighted, as at W, to counterbalance the weightsof the levers.

The construction is such that the fragile mantle may be employed in many positions where otherwise its use would be found impracticable. For street use'it will relieve the mantle from those constant and sudden shocks to which it is subjected Where there is heavy traflic. In portable lights its use will be found highly advantageous.

As will be readily appreciated, there are no springs to break or set, no liquid seals with their attendant expense and complicationsin fact, nothing which can get out of order, but a construction which is simple and efficient in its action.

the upper end thereof; a series of Weighted levers carried bya fixed portion of the burner; and connections intermediate said levers and the sleeve.

2. In a gas-burner, the combination of a gas-supply tube; a sleeve loosely encircling the upper end thereof; a mantle supported by said sleeve; and connections substantially such as described intermediate the sleeve aud a fixed portion of the burner permitting the tube and sleeve to move universally one relatively to the other when subjected to jar or the like, and to return the parts to their normal position.

3. In a gas-burner, the combination of a gas-supply tube; a sleeve loosely encircling the upper end thereof; a mantle supported by said sleeve; and a series of weighted levers flexibly connected to the sleeve an d fulcru med on a fixed portion of the burner.

4. In a gas-burner, the combination of a gas-supply tube; a sleeve loosely encircling the upper end thereof; a mantle carried by said sleeve; arms connected to the sleeve and extending downwardly therefrom; a series of levers fulcrumed upon a fixed portion of the burner; flexible connections intermediate the inner ends of said levers and the arms; and a weight adj ustably mounted upon the outer end of each lever.

5. In a gas-burner, the combination of a gas-supply tube; a mantle; means for suspending said mantle over the tube; and a series of weighted levers flexibly connected to said supporting means, whereby the tube may be tipped laterally or moved up and down independent of any movement of the mantle.

6. In a gas-burner, the combination of a gas-supply tube; a sleeve loosely encircling the upper end thereof, and free to rock or tip and to be moved up and down independently of the tube; a mantle supported by said sleeve; a series of arms connected to the sleeve and extending downwardly therefrom; a series of lovers fulcrumed upon a fixed portion of the burner; links connecting. the inner end of each lever to oneof the arms; and a weight adjustably mounted upon the outer end of each lever.

7. In a gas-burner, the combination of a gas-supply tube; a sleeve loosely encircling the upper end thereof; a mantle supported by said sleeve; a series of arms connected to the sleeve and extending downwardly therefrom a gallery surrounding the tube; a series of levers fulcr'umed on the gallery in line with the arms; links connecting the ends of the arms and the inner ends of the levers; and a weight adjustably mounted upon the outer end of each lever.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
