IMPROVED ATTACHMENT T0 LAMPS AND GAS-BURNERS FOR HOLDING VESSELS OR SHADES OVER THE FLAME.

Specification forming part of Letters Patent No. 40,617, dated November 17, 1803.

To all whom it may concern:

Be it known that I, WARREN L. FrsH, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful improvement in lamp attachments for supporting vessels or other articles to be heated for cooking and other purposes; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, which represents in isometical perspective view the support, subject of this patent, attached to a lamp. Various contrivances have heretofore been used for the purpose of utilizing the heat emitted by the illuminating-flame of a gas or oil burner. Many objections are urged against most or all of them. Thus, those applicable to gas-burners are necessarily complicated and heav inasmuch as in each a )ara-tus ro- .vision is or should be made for the proper admixture of atmospheric air with the hydrocarbureted gas, which necessitates the employment of a comparatively large vesselin which said admixture takes place. On the other hand, those applicable to coal-oil burners, as well as those last referred to, are open to the objection that by their use on a lamp or burner the flame is obscured, or, it provision be made for the transmission of light, as is the case in those patented to me on the 17th day of June, 1862, or where a support for a vessel is hun g on or clamped to the chimney, are still open to some objections-in the former case on account of the support and vessel requiring to be made expressly for and to fit the sides of the burner, and in the latter case because the lamp, by the employment of the support, is rendered top-heavy and otherwise exceedingly dangerous.

The object of my invention is to contrive a support for vessels and other articles to be heated by the flame of a gas or oil burner, which support shall be adjustable to and detachable from any lamp or burner, or any convenient part thereof, such support further presenting the advantages of not obscuring the light, of being adjustable as regards the height of the flame or the chimney, and being otherwise of cheap and simple construction,

and my invention consists, first, in combining a support for sustaining a vessel or other article to be heated with a standard-rod and adjustable clamp in such a manner that it may be attached to any convenient part of a lamp or burner, and when so attached shall hold the said vessel or article in a position immediately over the flame, substantially as hereinafter described; secondly, in combining with a support and suitable clamping device an extension standard-rod, adjustable, as hereinafter described.

To enable others to make and nse 1ny invention, I shall now proceed to describe its construction and operation.

A, in the accompanying drawings, is the support, consisting of a skeleton disk or of a circle or hoop, having in the plane thereof converging prongs B, for the purpose of supporting vessels of various diameters or size. To this support, at or near its periphery and at right angles to the plane thereof, is secured a rod or standard,which in this'in stan ce is shown to consist of two parts-i. e., a cylindrical sleeve, 0, and a shank or rod, 1), the former being secured, as stated, to the skeleton support, while the latter is fastened to a clamp. The sleeve snugly fits the rod and is capable of an up or down sliding motion thereon, so that the distance from the clamp to the support may be increased or decreased, according to circumstances, at pleasure. The adjustment of the sleeve upon the rod is effected by means of a set-screw, S, working in a screw-threaded enlargement on the sleeve.

The clamp above referred to and marked in the drawing M, consists of two curved jaws, hinged or jointed together by means of a traverse-pin, which, in this instance, is a prolongation of the rod D. The jaws are armed along their interior clamping-surfaces with studs or pins m, whereby a more perfect grip may be obtained. The clamping'may be efiected in various ways: In this instance a thumb-screw, T, is used. The jaws are extended beyond the hinge or joint that unites them, forming two branches, which may be spread by the said thumb-screw, it traversing a screw-threaded aperture in one branch and abutting against the other. It will be obvious that by turning the thumb-screw either to the left or to the right the two branches may be caused to diverge or converge, effecting the opening or less heated medium.

screw S, as hereinbefore shown. observe that instead of a skeleton disk for supclosing of the jaws'against the collar of the burner, or any other convenient part of a gas or oil lamp or burner.

Instead of the thumb-screw a spring may be used, interposed between the two branches. By'the latter arrangement the clamp is selfadjusting on being placed on the lamp.

From the above the use of my improved device for supporting vessels or articles to be heated over and by the flame of a gas or oil burner will be readily understood. The sup port, after being duly clamped to the burner or lamp, is adjusted as to height to clear the chimney or to bring the vessel into a more or When so adjusted, the adjustment is made fixed by means of the set- I would also porting the vessel or article to beheatcd,a clamp may be used, similar in construction and op eration to that described above. The vessel would, in that case, be held by a clamping support and would thus not be liable to slide or fall off the support.

In conclusion, I would observe that the apparatus herein described may be used for purin a position immediately over the flame, substantially as herein described.

' 2. The combinatiomwith a support and suitable clamping device, of an extension standardrod, adjustable substantially as herein described.

In testimony whereof I have signed my name to this specification before two subscribing witnesses.
