SELF-HEATING SAD-IRON.

To all whom. it may concern:

Be it lnown that I, HENRY l/V. Scrrorr, a citizen of the United States, residing at River Forest, in the county of Cook and State of Illinois, have invented a new and useful Self-Heating Sacllron, of which the following is a specification.

This invention relates to self-heating sad irons in which liquid fuel is used as a heating medium.

It is the object of the present invention to provide an improved burner structure which is adapted for hydrocarbons, as well as alcohol, and also to provide a burner which can be easily removed from the body of the iron, and all parts of which are readily accessible for cleaningY purposes.

lVith the foregoing objects in view the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawing hereto annexed in which- Figure 1 is a perspective view of the iron. Fig. 2 is a central longitudinal sectional view. Fig. 3 is a plan view of the iron with the cover removed.

In the drawings, 7 denotes the body of the iron, it being made hollow to receive the burner. The iron body has an open top which receives a removable cover 8 fitted,

with a handle 9. The top edge of the iron body has two recesses 10 in each side edge to permit the escape of the products of combustion from the interior thereof. The cover is locked to the iron body by a catch 11 pivoted to an inturned flange 12 on the top edge of the body near its rear end, and extending through a slot 13 in the edge of the cover, and over the top thereof. Upon swinging the catch away from the cover, the latter can be removed. The cover is further held in place by means of a prong 14 extending from the under side thereof. and adapted to enter a recess 15 made in the wall of the iron body on the interior thereof at its front end. The prong is forwardly presented and is made to enter the recess 15 upon sliding the cover forwardly. The under side of the cover carries a transversely curved deflector plate 16 which, when the cover is in place, extends into the interior of the iron body between the recesses 10 above the burner, and serves to deflect the products of combustion away from the top 8 and out said Specification of Letters Patent.

l recesses 10. The plate 1G carries prongs 16 entering eyes 1Gb on the wall of the iron body, which assist to hold the cover in place.

The burner comprises a hollow body 17 mounted within the interior of the iron body. Theaear end of the burner is curved upwardly slightly, and fits in a deep recess 1S made in the rear wall of the iron body. The frontend of the burner is formed with a foot 19 which engages the floor of the interior of the iron body, and serves to space the bottom of the burner therefrom. Said bottom of the burner is a plate 20 having a series of burner openings Q1. The burner is closed on top, and from said top rises a stem 22 with which the deflector 16 engages when said cover is in place. The foot 19, and the stem Q2 when the latter is engaged by the cover, serve to hold the burner in position within the iron body. The burner is further held in place by having upright grooves in opposite sides at its rear end as indicated at Q3 into which grooves the opposite walls of the recess 1S extend.

The herein described arrangement of parts provides a rigid support for the burner, and at the same time it may be readily removed from the iron body should it become desirable to do so. The recess 18 in which the rear end of the burner seats opens out the top of the iron body, so that upon removing the cover the burner may be removed by simply lifting' it out of the iron body.

The rear end of the burner is enlarged and raised as indicated at 25. and in said enlargement are fuel passages 2G and 27. The ends of these passages, on the interior of the iron body, are fitted with removable couplings QS by means of which a vapor generating tube 29 is connected with said passages.Y This tube is U-shaped in plan view as seen in Fig. 3. but forward of the couplings its body is dropped onto and in metallic contact with the top of the burner whereby it receives heat 1 therefrom, and the bend at its front end is engaged under a hook 30 formed on the burner body and opening to the rear. By having its rear portions raised above its flat body, the couplings 28 can be unscrewed to disconnect its extremities from the fuel passages, after which said extremities can be sprung upward, the whole tube swung around said hook as a pivot, and its bend Patented Feb. 2S, 1911. f

moved out from under said hook; and in this way the tube can be detached from the burner body for cleaning purposes.

To the ends of the passages 2G and 27 which are on the outside of the burner body, are connected a fuel supply pipe 3l, and a valve casing 32, respectively, the fuel pipe being connected to the passage 26, and the valve to the passage 2T. The fuel pipe carries a, tank 33 containing a supply of liquid fuel such as gasolene or alcohol. The valve 32 maybe formed integral with the burner body and the body of said valve consists of two angularly disposed tubes in line with the bore of one of which is an opening 34 constituting a seat for a needle valve 35 which works in said bore. Tlre stem of the needle valve is provided with a suitable handle 36, and the end of the bore through which the stem of the needle valve extends, is closed by a suitable packing nut 37.

The operation. of the burner is as follows: The liquid fuel passes from the tank through the pipe 3l into the passage 26 and ,from said passage to the generating tube 29, in which it is vapor-ized, and the vapor passes to the valve and into the body of the burner from which it issues through the openings 2l and burns at the latter. The Haines are deiiected downwardly against the bottom of the iron body which will be rapidly heated. ln view of the metallic Contact of the generating tube Q9 with the burner, the liquid fuel passing through said tube will be quickly vaporized.

On the cover S are socket pieces Lll whereby the handle 9 is secured. These socket pieces are skeleton in form intermediate their ends as indicated at et?, and are secured to the cover by screws or other suitable fastening means passing thereinto and through the cover from the under side thereof. The fastening means also pass upward into the ends of the handle seating in the sockets. Between the socket pieces and the cover are. interposed asbestos washers 44. which with said socket pieces prevent heat from being transmitted to the handle. rEhe products of combustion within the body of the iron and which must issue through the side recesses l0, are directed laterally out of them by the del/lector plate 16 whose body standing beneath the cover S therefore affords additional protection to the operators hand which grasps the handle.

lVhat is claimed is:

i. In a self-heating iron, the combination with a hollow body having an open top and two recesses in each side edge, a burner mounted within said body and having its forward end at a lower level than its rear end, a stem rising from said forward end, and means for supplying liquid fuel to the burner; of a flat top detachably secured to the iron body and extending over and resting upon the raised rear end of the burner, and a deiiector plate secured beneath the top and having its edges bent downward within the burner body, said stem engaging the center of theA detlector when the latter is in place. p

2. In a self-heating iron, the combination with a hollow body having an open top and two recesses in each side edge, a burner mounted within said body, and means for si|p] )lying liquid fuel to the burner; of a flat top detachably secured to the iron body, a handle secured to and insulated from the top, a curved detlector plate whose center is secured beneath said top and whose downturned edges carry prongs, and eyes within Vthe wall of the iron body engaged by said prongs when the cover is in place.

3. ln a self-heating iron, the combination with a hollow body` having a recess in its rear end, a tlattop detachably secured to the body, and handle; of a. burner ha ving a` hollow body raised at its rear end and engaging said recess, the raised portion being provided with longitudinal fuel passages, a tank and a valve connected with the outer endsI of said passages, couplings at their Vinner ends, a rearwardly facing hook at the front end of the burner body, and a U shaped vapor generating tube whose bend removably engages under said hook, whose legs lie upon the flatv top of the burner body, and whose extremities are upturned and engaged by said couplings.

In testimony that I claim the foregoing as my own, 'have hereto atliXed my signature in t-he presence of two witnesses.
