SPECIFICATION forming part of Letters Patent No. 728,116, dated May 12, 1903.

Application filed April 3, 1902. Serial Noa 101,246. (No model.)

To a/ZZ whom, it may concer-72,:

Be it known that I, WILLIAM A. KING, a citizen of the United States,residing at Pierre, in the county of Hughes and State of South Dakota, have invented certain new and useful Improvements in Self-Heating Branding- Irons; and I do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains` to make `and use the same.

My invention relates ,to a self-heating branding-iron designed forpusing gasolene or other fluid hydrocarbon fuel and adapted to be employed generally for stamping, branding, and for other analogous purposes for which a heated iron is required.

The device is especially designed for use in branding cattle; but provision is made for attaching any desired form' of branding-iron thereto.A

The object of the inventionis to providea device of this character which is simple, durable,.and effective in construction and wherein the parts are so combined as to secure an effective consumption of the fuel and to provide an easily-operated and compact forni of tool. Y

With this and other minorfobjects in View the invention consists of certain novel features of construction, combination, and ar.- rangement of parts, as Willbe hereinafter more fully described,`and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a side elevation of a self-heating brandingiron embodying my invention. Fig. 2 is a Vertical longitudinal section of the same.

reservoir for supplying air under pressure tou the tube while the inner end of said tube is threaded onto one of the reduced ends 2 of a coupling 3. Inside the tube 1 is arranged a second tube 4, having a longitudinal partition 6, forming induction and eduction passages 7 and 8 in communication through a port 5 at the outer end of said tube 4. The tube 4 thus forms, in effect, a tube, attached at one end to the coupling 3 and extending to near the rear end ofthe handle 1 and then bent centrallS7 upon. itself and having its other end open and extending to near the forward end of the handle 1, thereby forming an indirect passage between the reservoir and feed-passage 10. By this construction the column of liquid hydrocarbon flowing to the burner is red'uced'and is first caused to flow rearwartlly4 through the passage 7 and then forwardly through the passage 8, by which it is caused to feed more or less regularly and not by spasmodic jets or pulsations, as would be theicase were the passage 10 in direct communication with the reservoir. PassageS is provided with a nipple 9, which screws into a longitudinal feed-passage 10 in the coupling 3. Into the opposite reduced end 11 of the coupling 3 is Hthreaded a generating tube or pipe 12, which is 'in communication with the said passage 10 and is connected at its forward end to the base portion 13 of a Bunsen burner 14. A threaded collar or nut 15 engagesthe end 10 of the coupling 3 and surrounds the tube 12. This collar or nut contains packing 16 to prevent leakage of the hydrocarbon. The said base portion 13 of the burner 14 is provided with a feed-port 17, through which the vaporized hydrocarbon passes into the burner-chamber, and this port is governed'bya needle-valve 18,`whose stem 19 extends through the tube 12 and is rigidly screwed or otherwise secured at its rear end in the coupling3. An annular knurled knob or handpiece 20 is secured to the tube 12 between said coupling and the burner and is employed for turning said tube to regulate the supply of fuel tothe burner. By holding the handle 1 firmly in one hand the tube 12 may be screwed in an inward or outward direction in the coupling 3, thereby moving the port 17 toward or from the valve 18 to cut off and regulate the feed of fuel to the burner Vas required. t.

The burner 14 consists of a tube having a combustion-chamber 21 open at its outer4 end and provided with air-ports 22. At itsouter end the burner is threaded, as shown at 23, to receive the branding-iron to be heated. A bulb or cup 24 is secured at its rear end by a Ioo ring 25 to the burner-hase and Surrounds the rear portion of the burner. This cup is open at its forward end and is adapted to receive a supply of alcohol or gasolene to preliminarily heat the burner and gen erating-tnbe to start the generation of gas.

In operation the base of the burner and the tube 12 are heated from the burner, which also heats the iron, and the gasolene passing therethrough is converted into gas or vapor, which admixes with the air and passes to the combustion-chamber, where it is consumed. The amount of gas fed to the burner and the heating of the iron may be regulated by adjusting the handpiece 20 in the manner here tofore described.

It will thus he seen that my invention pro- Vides a simple, compact, and convenient de vice which is readily handled and may he employed for heating branding irons of all kinds.

IVhle the preferred embodiment of the invention is herein disclosed, it will of course be understood that changes in the form, proportion, and minor details of construction of the parts may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s-

In a self-heating iron of the character set forth, the combination of a tube forming a handle and a hydrocarbon-reservoir, a burner having a feed-port, a coupling connected to the reservoir and having a feed-passage, a cond noting-tube arranged within the handle and having one end communicating with said feed-passage and thence projecting backwardly to near the rear end of the tube and thence being bent upon itself and having its opposite end open and extending forwardly to near the front end of the handle, thus forming a restricted indirect passage for the flow of the hydrocarbon from the handle to the feed-passage, a generating-tube adjustably connected to the coupling. and carrying the burner, a valve governing said port and having a fixed position, and means for adjusting the generating-tube to move said port toward and from the valve, substantially as described.

In testimony whereof I have hereunto set my hand in presencelof two subscribing witnes-ses.

WILLIAM A. KING.
