UNITED STATES DANIEL A, JERAL D, OF OSAGE, IOWA.

SELF-HEATING IRON.

No. 873,942. Specification o Application iilocl May To all whom it may concern: I

Be it known that I, DANIEL A. JERALD, citizen of the United States, residing at Osage, in the county of Mitchell and State of Iowa, have invented certain new and useful Improvements in Self-Heating Irons; and I do hereby declare the following 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 new and useful improvements in irons and more particularly to that class adapted to be used by tailors for pressing seams or the like.

My object is to provide a suitable heating appliance for the iron whereby the same may be continuously heated while in use.

A further object is to provide means for supporting a fuel containing tank upon the A still further object is to provide means for cleaning the jet tube of any sediment which may accumulate therein.

A still further object is'to provide means for readily and quickly heating the jet tube and thereby increase the generating efflciency of the parts.

Other objects and advantages will be hereinafter made clearly apparent in the specification and pointed out in the claims.

In the accompanying drawings I have shown the preferred form of my invention.

In said drawings-Figure 1 is a perspective view of my improved iron showing the same at rest and placed upon a suitable stand. Fig. 2 is a central, longitudinal, sectional view through the iron. Fig. 3 is a detail sectional view through one end of my improved iron as seen from line 3-3 Fig. 2 with the generator removed therefrom, and, Fig. 4 is a plan view of the generator removed from the iron.

Referring to the figures by numerals of reference, 1 indicates the body portion of my improved. iron to the upper end of which is secured a covering 2, said covering being provided with depending arms 3 which extend on the inner side of the body 2 and are secured thereto by means of bolts or the like 4, said bolts passing through the body portion 1 and into said arms. One end of the body 1 is provided with a way 5 and in this way is seated a generator 6, said generator being secured in the way 5 by providing the edges of the wall 7 With grooves 7, said f Letters latent.

grooves being designed to engage the adjacent walls of the way 5 and hold said valve headsecurely in place. The upper end of the valve head 6 is provided with a controlling valve 8 by which means the flow of oil or gas through the passage 9 may be controlled. At the lower end of the passage 9 I. provide a jet tube 10. said tube extending beyond the face of the valve head 6.

In using certain grades of oil and gases, the jet tube becomes foul and clogged and in order to remove the accumulation of sediment therein, I have provided a pin 11, said pin entering the valve head through the packing box 12 and has on its inner end a pentagonal needle point or projection 13, said projection being of SllfllClQDt length to pass entirely beyond the end of the jet tube and the pin being so arranged that it can be readily drawn outwardly to remove the projection from the jet tube and passage 9 thus removes all sediment. Extending longitudinally through the body 1 and in line with the jet tube 10 is a tubular burner 14, one end of said burner being open and extending through the wall 7 while the opposite end thereof is supported in a block 15 which extends around said burner and rests upon the base 16 of the ,body portion 1. Extending longitudinally above the burner 14 is a generator or retort 17, one end of said tube being in engagement with the tubular bore 18 in the valve head 6 while the opposite end thereof is extended through the front end of the body 1 and is directed upwardly and has secured thereto a tank 19, said tank being designed to receive the fuel, such as oil or the like. The upper end of the tank 19 is provided with an opening 20 in which is seated a suitable closure cap 21 so that when it is desired to fill said tank, the cap 21 may be removed and the fuel inserted through the opening 20. The cap 21 is provided with a longitudinal bore 22, said bore extending substantially through the cap from the upper end thereof, the lower end of the bore 22 being reduced in size and adapted to receive the reduced end of a plug 23, said plug being provided with a longitudinal bore 24* through which air is introduced into the tank 19, thereby placing the liquid fuel contained therein under pressure. The upper end of the plug 23 is enlarged and provided with. a suitable socket in which is adapted to be seated one end of an air pump (not shown). l/Vhen it is desired to inject air into the tank, the point of the plug 23 is removed from the reduced end of the bore 22 by turning said plug and the air pump secured to the enlarged end of the plug and after a sufficient amount of air is forced into the tank, the plug is again turned down until the reduced end thereof is again seated in the be bore 22. The cover 2 is provided with a suitable handle frame 25 said handle frame being substantially U-shaped and has secured between thev upper ends thereof a handle 26. The forward end of the handle frame 25 is elongated as shown at 27 and disposed into connection with the upper end of the tank 19 and is secured thereto by means of a bolt 28 or'the like.

The walls of the combustion chamber formed by the walls of the body 1 are pro- Vided with elongated slots 29 at their upper edges through which the heat escapes from the iron while the lower edges of said walls are provided with draft ports 30. The base 16 of the body 1 is elongated at its rear end and extends below the generator 6 .and is provided at a point immediately below the jet tube with a depression 31, said depression forming a cup for the reception of oil. When the iron is not in use, the same may be disposed upon a suitable stand 32, said stand being provided with supports to elevate the same from the article upon which the supports rest.

In operation, the controlling valve 8 is elevated and a supply of oil allowed to pass through the passage 9 and jet tube 10 into the depression 31 in the base 16 after which the controlling valve is closed and the oil in said depression ignited, and as the jet tube 10 extends directly over the depression 31, the same will be quickly heated so that when the controlling valve is again opened, the oil passing through the passage 9 will be gener ated into gas and directed into the tubular burner 14, it being understood that as soon as the retort 17 is sufficiently heated, gas will generated in sufiicient quantity to supply the burner, After the generator has been m l l l use for some time and the bore in the jet tube becomes clogged, the pin 11 is directed inwardly and the projection 13 thereon passed through the bore in the jet tube, thereby cleaning the same of all obstructions. If de sired a small quantity of wood alcohol or the like may be placed in the depression 31 and partially consumed before the valve 8 is opened.

What I claim is The combination with the body portion, of a block resting on the base thereof at one end, a valve head at the other end resting on said base, a tubular burner supported in said block and valve head, a covering for said body having depending arms extending on the inner side of said body, means on said body engaging said arms to secure the covering in place, a retort extending longitudinally of the body above the burner, a controlling valve on the valve head, and a jetpiece in said head at right angles to said valve, and in line with the open end of said burner.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DANIEL A. JERALD.
