Be it known that I, J QHN FRANKLIN, zen-of the United States of America, and a resident of Norwood,'in the county of Hamil ton and State .ofOhio, haveinve'nt'e'd certain new and useful Improvements inAntivibratorySu'pports for- Gas-Burners, of which the following is a specification. 1

Thisinvention relates to certain improvements in antivibratory supports for gasburn "ers, being especially adapted for-overcoming vibrationiin street and'factory gas-lamps, so

as to prevent damage to the; frailincandescent mantles commonly used upon such "lamps audthe object of the invention is to provide a device oft this character whichshallbe of a simple and inexpensive nature and not liable to become'deranged or broken when in use.

The' invention consists in certaininovel tea a. I tures of the construction, combination, and arrangement of the sei eral,partSOf'the improved antivibratorysupporting device,

Referring, primari1y,to Figs. 1 to 4', l indicates the gas-supply pipe, and Zindicatesthe cock controlling the flow .of "gas through the same. 3 '3 indicateburnerssuppliedfrom the pipe 1 and carried oniarms 4 4, extended from opposite sides of a burner connectiou fi, between whichand-the'cock-2 is arranged the improved antivibratory support, (indicated as a whole by'6.)' "The burners 3 maybeof any preferred kind, being usuallyof the Bunsentype, havingiucandescent mantles suspended 'above them in awell kiiown'way,jandfthere may beflbut' one or an'yjnumber of burners'B 1 instead of two such burn ers,.as herein shown.

The device 6 compri ses, a s shown in these'ctionalfview, Fig. 2,,a cup-shaped par-torrecept'acle 7, having athreaded socket 8 at-its base, to receive the threaded upperend of the'vgas-pipe and provided with a vertical,

socket 8. The stem 9 extends up above-the top,v V

of the receptacle] and forms between itself and the walls ofthe-receptacle an annular space-poi chamber 10, adapted to hold a supplyofmercury, as indicated at 11, the upper edge'or top' of thereceptacle-wall being, by

preferencdformed with an upturned annular part with a horizontally-projectingannular flan e 14, to which are'he'ld at sui The by means of screws '15 or thejlike" the arms 16 of a 'sheet-metal' spring, preferably con- .struted'; as shown inFig, 4 of a single piece 17 ,having four integraldivergingarms. The

central aperture of the body 17 ofthe spring servesfor the passage of the-threaded upper of sheet n1eta lsuch as copper, bra'ss, or other end 18 of a tube ,19, which screws into the lower part2lof theburner con-nection5 and has formed on it below its screw-threaded part an annular flange, between which and the under side of the burner connection 5 the body portion 17 of the spring is clam ped. In

this way it will be seen that the burners 3 3 v are held elastically supported over the receptacle 6, with its gas-passage communicating tacle, so'that a seal is formed between the tube 19 and stem 9 in such a way as to prevent the escape of gas from the gas-passage of the stem, such gas being thus caused to pass through the bore 20.01" the tube -19 up into the burners 3above the same, By this construction it will be seen that when the parts are assembled the spring-arms '16 will afford a yielding or elastic support for the hu rner and will act as a cushion between the same and the gas-pipe, so that the vibrations and jarring of'the pipe will be received and neutralized, by said cushion and will not be transmitted. to the burner, as is the case in lamps constructed in the ordinary manner. In this way it will be seen that the extremelyfrail incandescent mantles used upon the burners are protected against injury from sudden jars and vibration, and the cost of.

maintaining the burner is thereby materially lessons 9.. rangement of the tube 19 with its lower end inclosing the stem f the receptacle acts as a stop to prevent excessive swayir movement of the burner upon its elastic suppoi t,

vwhereby damage to the spring-arms themselves is avoided, and, furthermore, the mer cury held in the chamber 10 acts not merely as a seal to prevent the escape of gas between the tube 19 and the stem 9, but also serves to. check the vibration of the burner upon its elastic supports.

In Fig. 5 I have shown the application of the improved antivibratory support to an ordinary street-lamp. In this view, 22 indicates the lamp-post, and 23 the globe inclosin'g the burners, which latter may be of the kind shown in Fig. 1 and provided with incandescent mantles m. The improved antivibratory support isarranged between the gas-cock 2 and the burner connection 5, as in the previous case, and serves to prevent the mantles from being broken or damaged when the post 22 vibrates or is shaken by the wind or from any other cause. In connection with street-lamps I prefer to use a gas-cock and.

It will also be seen that the armovably connected with the tip 24, and are 'co'nsequently'capable of free movement upon their support relatively to the said auxiliary tip. The cock 2 is a, three-way cock and when turned first supplies gas to' the auxil iary lip 24, to which a match or torch may be ap' lied, causing the gas escaping at said tip to urn in a long jet beside the burners 3. Upon further turniugmovement of the cock 2 the gas is turned on to the burners 3 and is cut ofi? to the auxiliary tip 24, so that the jet from said tip 24 before being extinguished will serve to ignite the gas at the burners. In this way the mantles are further protected from injury, since the cock and auxiliary tip 24 being flexibly or movably connected by the autivibratory support with the burner the gas may be turned on or ofi without danger of unduly jarring the mantle, andthe'lighter is not required to apply his torch or match to the burner itself, but merely to the auxiliary tip 24, and consequently the risk of damage upturned barrel-like flange 30 and inside said flange,a tubular stem 31, an annular space or mercury-chamber 32 intervening to receive the depending tube 33 of the upper member or part 25.

mercury in chamber 32 forms a seal to prevent the escape of gas between the two parts, and said parts are movably connected by bent springs 28, extending between them. Chains 29 or other like devices also connect the parts 25 and-26, so that in case of breakage of the springs 28 the burner 27 will-be supported against falling. If desired, also,

the mouth of the mercury-chamber'32 may be formed with an annular inturned li-p similar.

vibrations and jars which would otherwise be transmitted direct to the burner and its mantle, and thereby prevents damage to the mom tle and greatly reduces the expense of maintaining the lamp. It will also be obvious from the above descriptionof the invention that the device is capable of considerable for this reason I do not wish to be understood as limiting myself tothe precise form and arrangement of theseveral parts herein set forth. a

Having thus described my invention, I claimr 1. A-device for overcoming vibration in gas-burners comprising a burner connect-ion, a tubular part screwed in'tosaid connection,

tween the burner connection and the tubular part and provided with diverging arms integral with said body portion, a, part to which -the arms of the spring are connected and which is adapted for connection with a gaspipe and has a gas-passage adapted for communication with the bore of said tubular part, and means for preventing the escape of gas between the two parts,-substantially as set forth.

2; An antivibratory supportfor gas-burners and the like comprising two parts formed with -corresponding gas-passages and a strip of spring material having its central portion secured to one of said parts and its end portions formed *into'spring-arms each extended across the space between the two parts of the v support and secured to theother part of the 3osupport, substantially as set forth. a

3. An antivibratory support for gas-burners and the like comprising two parts having corresponding gas-passages and a strip or pieceof spring material having at itscentral 35 portion a perforation, a hollow plug passed through said, perforationand engaged with v one part of the support for holding the central portion of thestr'ip thereto,the end portionsof said strip being formed intospring; 4o arms each extended across the space between the two parts and secured to the other part of the support, substantially as set forth.

4. A device of the character described comprising a gas-cock, a main gas-burner and an 4.5 auxiliary tip having independent gas 'conuections whereby each is supplied with gas through said gas-cock, and an elastic supporting means whereon the main gas-burner is held for movement relatively to thesaidsq auxiliary tip, substantially as set forthfg Signed by me at Cincinnati, State of Ohio this. 13th day of January, 1900.
