Patented Dec. 28, 1909.

Application tiled February 15, 1909. Serial No. 478,054.

To all idiom. it muy concern: Be it known that I, JOHN Bonnxs, a citizen of the United States, residing at Dunkirk.

in the county of Chautauqua and State of t New York, have invented a new and useful Self-Heating Sad-Iron, of which `the following is a specification.

This invention relates generally to self heating sad irons, and more particularlyv to one of that class employing gas as a fuel.

The object of the invention is to improve the manner in which the heating medium is disseminated within the body of the iron, whereby to utilize practically all of-the heat units for performing. effective work, and` so to ventilate the body that perfect combustion will ensue, thereby preventing smoking and thus the escape of disagreeable odors, and further to protect the hand of the user from injury or discomfort from escaping heated air.

lVith the above and other objects in view, as Awill appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a self heating sad iron, as will be hereinafter fully described and claimed. In the accompanying drawings forming a part of this specification, and in which like characters of refcrenceindicate corresponding parts: Figure 1 is a view in perspective of a sad iron constructed in accordance with the present invention. Fig. 2 is a View in vertical longitudinal section, on an enlarged scale. Fig. 3 is a transverse sectional view on an enlarged scale. .j

The hollow body l of the iron is shown as fusiform in contour, although it may be of any other preferred shape, and is provided near its face and adjacent to its u'pper edge with rows of orifices 3 and 4 respec;

tively, through the former of which cold air is drawn to support combustion; through the latter heated air escapes.

Projecting beyond one end of the body is a boss 5 in Which is secured one end of a burner tube 6, the other end of which is secured in a boss 7 projecting inward from the innerV wallvv of the nose of the body. This tube is provided along its under side. with orifices 8 through which the mixed gas and air escape to the body and are ignited. The

means for mixing the fuel and air consists of an ordinary mixing chamber 9 that is secured to the boss 5 by screws 10 and in the end wall of which is secured a union 11 l carrying a jet 12 and a valve 13. The union is designed to be connected with a gas jet i by a flexible pipeas usual. In order to conj serve the heat units, and check their too i rapid escape, the bottom of the body conj tains a loose mass 111 of a refractory inaterial, Such as asbestos wool, which may partially, or wholly, surround the burner tube, as shown in Fig. 3. This'fiiling will also prevent passage externally of the body of tongues of ame, and thus in a positive manner preclude danger of injury to the user. f

The cover embodies two spaced plates '15 and 16, the former of which is provided with a depending tiange 17 having orifices 18 that register with the orifices 4: of the body. Secured to the plates and 16 and conforming in shape to the perimeters thereon its under side with spaced orifices 2O that. register with similar'orifices 21 in the, plate 15 and at its outer side with orifices 9.2 that discharge air laterally at points farthest removed from the fuel, whereby such air is cooled sufficiently to remove all danger of burning the user of the iron.

15 is a block 23-of asbestos, and disposed between the plates 15 and 1G is a second block 24C of asbestos, and the-se blocks are of such thickness that they lag the plate 16 to such an extent as to prevent it from becoming hot enough to burn the hand.

The plate 16 has secured to it a handle 25` of any preferred construction, between the base of which and the plate is interposed a vsheet 2G of insulating material. In order to ignite the burner tube there is a perforated tapered door 27 provided whichl fits a similarly shaped opening in the side of the body and has secured to it one end of a spring 28 the other end of which is riveted or otherwise assembled with the body.

In using the. iron., the union is connected with a gas jet Ain a manner that will be understood, and the valve 13 is opened thus allowing the gas to pass to, the mixing chamber and thence to the burner, where it yis ignited at the door 27, the same being turned to one side for the nurpose. The ignited gas jets discharging rom the openings S insinuatc themselves through the loose asbestos wool and cause it to become incandescent, whereupon it willsheat the body rapidly and easily. As will be ap- Secured to the under side of the plate of is a Ventilating tube 19 which is provided i i through the openings 2l and 2Q.

parent, air to support combustion will be drawn in through the openings 3 and after circulating through the body will escape In its assage toward these openings, the heated air establishes-an injector action at the openings i8 and 4 which operates to draw cool air into the upper portion of the body and thus prevents the cover from becoming heated to a degree that would be uncomfortable to the hand of the user.

The improvements herein described While simple in character will be found of the highest efiiciency in use, and Will coperate in the production .of a practical and durable form of sad iron.

`What is claimed is:

i. A iron comprising a body provided near .its face and upper edges with orifices, a burner tube arranged Within the body, a filling of loose fibrous refractory material surrounding the tube, means for supplying a combustible fluid to the tube, and a cover embodying a depending flange having orifices registering with those of the upper portion of the body, and a Ventilating tube combined with the cover and having orifices communicating with the interior of the body and also having orifices communicating with the external air.

2. A sad iron oomprisin a body provided near its face and upper e ges with orifices, a burner tube arranged within the body, a filling of loose fibrous refractory materia-l surrounding the tube, means for supplying-l a combustible fluid to the tube, a 'cover embodying a depending :flange having orifices registering with those of the u per portion of the body, a .Ventilating tube combined with the cover and having orifices communi.-

upper portion of the body, a Ventilating tube combined with the cover and having orifices communicating with the interior of the body andthe external air, and lagging material interposed in said cover and secured t'o the lower surface thereof.

4. A sad iron comprising a hollow body portion, means for conducting the hot air off and supplying cool air in the place thereof, a burner tu e arranged in said body portion, a filling of loose refractory material surrounding the tube, means for supplying a combustible fluid to the tube, a cover embodying a depending flange having orifices registering with those of the upper portion of the body, a ventilating tube combined with the cover a-nd'having orifices communicating with the interior of the body and the external air, and means disposed in the side of said body whereby a 'et may be ignited.

In testimony that I claim the foregoing as my own, I have hereto affixed my signa-A ture in the presence of tivo witnesses.
