HEATING SOLDERING-TOOLS 'BY GAS.

Specification of Letters Patent No. 17,301, dated May 12, 1857.

To all whom it may concern:

Be it known that I, J. HENRY STIMPSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Mode of Heating Soldering-Irons by Gas; and I do hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings and to the letters of ref-. erence marked thereon.

The design of the contrivance is to get the requisite amount of heat in the solderingiron with a small consumption of gas.

A is a stand which supports the iron in an upright position while heating. S, the soldering-iron, is nearly inclosed by the cylindrical chamber E, which chamber is perforated with small holes, and has free communication through the hollow pipe and handle N N-H H. The set-screw f confines the copper in its place.

0 C is a cylinder supported by M, surrounding the coppers, two of which are heated together. This cylinder G serving to concentrate the heat, is open at its lower extremity, allowing a constant supply of air. It is advisable to have a damper at the upper end to regulate the draft.

I As this apparatus is designed to be placed on the work bench, all noxious vapors ordinarily caused by combustion, may be carried off by a flue-pipe as in case of a charcoal furnace.

Instead of the hollow handle N H a separate supply-pipe might advantageously be used.

The pipe N fitting the hole in the stand A supports the soldering-iron in an upright position.

3 y are nippers which by the force of spring 9 are made to pinch the flexible supply-pipe G, thereby shutting ofl the gas when required. The sliding pin n is also acted on by g and moves simultaneously with y.

The gas passing through G N, is ignited as it passes out of the perforated cylinder E, a small amount being burned on a large surface, thus completely encircling the coppers and inclosing them in a sheet of flame (shown by the dotted line). When a copper is sufficiently hot it is taken from the stand. The pin a being thus relieved of the pressure of N N in the socket, immediately acting in concert with y shuts off the gas from the copper thus removed, and one copper only is left burning. WVhen the copper is replaced in the stand it immediately takes fire from the other, which may now be used in its turn. 7

I do not claim using flexible tubes or a hollow handle for heating soldering tools by gas, as this has been done before; but

I do claim 1. The perforated cylinder E, inclosing the soldering copper, in combination with the cylinder or chamber C, C, which concentrates the heat as herein stated.

2. Detaching the soldering tool and'regulating the supply of gas by compressing the pipe G, substantially as described.
