GAS-SAVING ATTACHMENT FOR HEATING TOOLS. No.1'79,330.

Patented June 27,1876.

UNITED STATES PATENT THOMAS MoKEE,'OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 179,330, dated J one .27, 1876; application filed May 29, 1876.

To all whom it may concern:

Be it known that I, THOMAS McKEE, of the city of New York, in the county of New York and State of New York, have invented a certain new and useful Gas-Saving Machine;

and I do hereby declare the following to be a v casin g a lever and spring attached to the cock,

which is operated on by the pressure of a tool laid 011 for the purpose of heating the weight or pressure of said tool, turning on the gas as long as required to heat the tool. Upon the pressure being removed, the spring turns off the gas, leaving only a faint glimmer, sufficient to keep the gas alight till required again, thereby causing a saving of gas to the extent of three hundred per cent., and a saving of time also, since the machine is self-acting, and requires no attention to turn the gas ofl' and on.

This invention has relation to the means for heating various kinds of tools by the use of a gas-jet, and has for its object the saving of gas by causing it to flow, only when a tool is being heated, and to be automatically shut 05 as soon as the tool is removed.

This invention, accordingly, consists in the novel construction of a device or stand containing a lever, spring, &c., and applied to a gas-burner in such a manner that as soon as a tool is laid upon the stand the gas will be turned on by the weight of the tool acting upon the valve through its connections, and that as soon as said tool is removed the gas will be turned down through the action of the spring, all as hereinafter described.

Referring to the drawings, A designates a stand of any desirable shape, and adapted to I be secured to or sup orted upon a bench, table, or other support. B B are forked standards rising from said stand to receive the tool, such as a soldering-iron or the like. 0 represents a gas-pipe rising at one end of, and, if desired, through the-base of the stand, and provided with a burner, c, and cock at. D is a hori zontal shaft, forked at one end to grasp the cock, and journaled to one end of the stand. A crank, e, connects this shaft with a lever, g, which extends upward across the recess or fork of the standard B at one side thereof. This lever is notched at h for the engagement of a dog, '6. A spring, 70, supported by a stud or arm, l, is arranged to bear against the crank, and operate in turning the shaft. The dog is intended to resist the tendency of the lever to move too far toward the center of the fork and obstruct the passage of the tool.

The operation will be easily understood. When a heavy tool is placed in the forked standards, the lever is forced to one side, causing the shaft to be turned through. the medium of the crank, which, at the same time, compresses the spring. By this motion the cock is turned, and the gas, already lighted, is raised. Upon removing the tool the spring reverses the shaft, turning down the gas and preventing waste.

Having described my invention, I claim The combination, with the tool-stand A, of the lever'h and shaft D, constructed and operating substantially as described, to raise and lower the gas from a burner by turning the cock 0, when a tool is placed on and removed from the stand, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of May, 1876.
