ATTACHMENT FOR WELSBACH OR SIMILAR GAS-BURNERS.

SPECIFICATIOK forming part of Letters Patent No. 734,668, dated July 28,1903.

Application filed May 14, 1903. Serial No. 7,142. (No model) To all whom it may concern: I

Be it known that we, GEORGE MAXWELL CLAGETT and SARAH CHELSEA CLAGETT, citizens of the United States, residing at No. 409 Third street, Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Attachments forWelsbach or Similar Gas-Burners, of which the following is aspecificatiomreference being ghad therein to the accompanying drawings.

Our invention relates to gas-burners of the Welsbach type; and the object of the same is to provide means to be associated with the ordinary fixture to prevent the mantle, which forms the incandescing medium, from partaking of any vibratory movement to which the gas-fixture may be subjected, and thereby prevent the bottom or unsupported end of the mantle from striking against the contiguous portion of the burner and by reason of the jar received from such impact breaking or cracking, and for supporting the same near its lower end for other purposes.

To this end the invention includes the combination and arrangement of component parts, to be hereinafter described, and particularly pointed out in theclaims.

While the invention is susceptible of various modifications, we have illustrated in the accompanying drawings and shall hereinafter describe what is now conceived to be the pre ferred embodiment of. the same.

In the drawings, Figure 1 is. a side elevation of a gas-fixture embodying our invention. Fig. 2 is a detail plan View, and Fig. 3 is a detail view of the attachment separated from the fixture.

As is well known, the mantles used in the Welsbach type of incandescent burner are constructed of extrem ely fragile material, and

such mantles are usually suspended at their upperends from a wire support, while their lower ends, which extend over the mixing tube or burner proper, are entirely unsupported. The lower ends of the mantles in order to fit easily about the burners are made of greater diameter than thelatter, and as said Inantlesare suspended, as premised, at their upper ends heretofore when the fixture has been subjected to vibration the same has been transmitted to the lower end of the manother purposes, such means being so constructed as to engage the unsupported portion of the mantle firmly yet ligh tly, -so as to avoid fracture thereof. I i

The means disclosed in the drawings for effecting the ends sought include generally a part for engagement with the mixing or burner tube, a part or plurality of parts for engagement with the mantle-at the lower portion of the same, and a flexible arm carrying each of the parts engaging the mantle, having means associated with the same for adjusting its position. I

In the accompanying drawings the mixing or burner tube is indicated by the letter a, the mantle by the letter I), and the Wire support therefor by the letter 0.

The means for engaging the mantle for steadying the same in the present exemplification of ourinvention include a base portion d, surrounding and embracing the tube a, and oppositely-arranged segmental members 6 for engagement with the exterior of the mantle at the lower portion or end of the same. Each member a is connected to and supported from the base portion d by a flexible or yielding arm f.

The present invention contemplates equipping the conventional form of Welsbach burner now in common use with the mantlesteadying means, and to this end the base 01 is preferably formed by a split corrugated ring or section of a ring, the ends of which are designed to be spread to permit the steadier to be applied to the mixing-tube andwhen freed to contract to engage the tube, and thereby frictionally hold the steadier in place thereon.

In order that the members e, which en to firmly yet lightly make contact therewith, the arms fare provided with means for adjusting them radially in reference to the burner or to and from the sides thereof. To this end each arm is preferably provided with a screw, the inner end of which finds a bearing against the outer periphery of tube a or other contiguous appliances of the burner.

The mantle is fitted to the fixture in the usual way, being supported at its upper end upon the angular-bent end of the wire 0 and having its lower end passed over the upper end of the tube Ct. In order that the said lower end may be properly fitted to the tube, the members 6 are spread a distance apart, and after the mantle is properly suspended the screws 9 are manipulated to permit the tension of the armsfto move the members 6 inwardly until the latter lightly engage the lower portion or end of the mantle.

While in the present exemplification of our invention we have shown two segmental engaging members 6, as will be understood said members may be formed integral.

In applying the steadying device to the burner the same is preferably so placed as to bring the supporting-wire c in the space between the ends of the members e.

The construction and operation of our invention will be readily understood upon reference to the foregoing description and accompanying drawings, and it will be appreciated that the parts and combinations recited may be varied Within a wide range without departing from the spirit and scope thereof.

What we claim as new, and desire to be secured by Letters Patent, is-

1. The combination with a fixture, comprising a burner-tube and a mantle freely supported at its upper end, of means for steadying the lower portion of the mantle, comprising a base supported upon the burnertube, andsegmental members engaging the lower portion of the mantle supported from said base, substantially as described.

2. The combination with a fixture, comprising a burner-tube and a mantle freely supported at its upper end, of a steadying device comprising a base fitted to the burner,

segmental engaging members coacting with the lower portion of the mantle, and means for adjusting said segmental engaging portions radially of the burner, substantially as described.

4. The combination with a fixture, comprising a burner-tube and a mantle freely supported at its upper end, of a steadying device comprisinga base fitted to the burner, segmental engaging members coacting with the lower end of the mantle, yielding arms carrying said members, and means for adjusting said engaging members radially of the burner, said means comprising screws carried by said arms, the inner ends of which find bearings upon the burner-tube, substantially as described.

5. A steadying device for incandescing mantles of gas-burners, comprising a base portion formed of a yielding ring-section, op-

ositelv-arran ed se mental mantle-en a in o b b e 3:

members, and spring-arms formed integral with said section and base portion interposed between the same, substantially as described.

6. A steadying attachment for gas-burners, provided with incandescing mantles, comprising a sectional ring, vertical yielding arms extending from opposite sides thereof and formed integral therewith, and horizontally-disposed sectional engaging members surmounting said arms, substantially as described.

In testimony whereof We affix our signatures in the presence of two witnesses.
