SAD-IRON.

Specfication of Letters Patent.

Application filed November 26, 1913.

Patented June 2, 1914.

serial No. 803,221.

To all whom it may concern Be it known that I, RALPH E. HART, a citizen o-f the United States, residingl at Geneva, in the county of Adams and State of Indiana, have invented certain new and useful improvements in Sad-Irons, of which the following is a specification, reference being had to the aceon'panying drawings.

This invention relates to new and useful improvement-s in sad-irons and inore particularly to a self-heating sad-iron, the object ofthe invention being to provide a selfheating sad-iron having` a fuel reservoir eX- posed to the heat produced at the burner 'whereby the contents of the reservoir are vaporized, furthermore to provide means whereby the reservoir forms a heat guard to protect the hand of the operator and furthermore to provide a device whereby the burner may be replaced when desired or necessary and is securely held in position when in use.

Another object of the invention is the provision of a self-heating sad-iron of the above character which will possess adva'tag'es in points of efliciency and durability, is inexpensive to manufacture and at the same time is simple in construction and operation.

lVith the above and other objects in view the invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings, in Which- Figure l :is a. side clevatiou of my improved self-heating iron illustrating` the manner of heating the generating` pipes; Fig. 2 is a rear end elevation; Fig. is a transverse Sectional view; Fig. L t a longitudinal Sectional view of the burner: Fig. is a transverse sectional view of the feed pipe; Fig. 6 is a detail plan view of one end of the handle; Fig. 7 is a transverse Sectional, view through the supply tank; Fig. 8 is a bottom plan view of the supporting; plate; Fig. 9 is a detail plan view of one end of the base or shell; and Fig. 10 is a detail perspective view of the guard plate.

Referring more particularly to the drawings, 1 indicates the base or shell of the iron provided with a cavity forming a combustion chamber, suitable openings 2 being formed in the sides of the conbustion chainber at the outer edge of the shell for the escape of products of combustion. The shell or base l is provided at its rear end with a vertical recess 3 and further provided upon 'acli side of the recess with upwardly pro- Jecting perforated ears Ll. The base or shell 1 is provided at its f rward end with a rccess 5 which forms a vertical. wall 6 having a threadcd opening therein in which is arranged the set screw 7. the purpose of which will be hereiuafter more fullv set forth.

The heating,` i ortion of my improved sadiron includes a plate 8 which is adapted to rest upon the upper edges of tho shell .1. The plate 8 is provided at each end with outwardly projecting ears 8' and formed inleg'ral with said ears are the parallel uprights 10. The upper ends of the uprig'hts 10 are arranged within the recessed ends oi the handle member 11 and secured in position by means of the screws il'l'ouutcd upon the plate 8 and arranged between the uprights 10 is a rescrvoir 13 which is adapted to contain herosene oil, gasolene or aur other desirable fuel.

The feed pipe 14. conuects with the interior of the resei'voir 13 at one cnd thereof, as shown at 15, said pipe thence extending' rearwardly to the rear of the device, thence bent upon itself and engaged over the burner 10. thenee running forwardly and then bent upon itself and extending rearwardl)7 to the connecting pipe 17, said connecting pipe having an angular portion 18 formed integralV therewitl in which arranfjed a valrc 19, said valve regulating the flow of gas into the rear end of the burner 10. The two lonj ritudinal portions 20 of the pipe l-l arc. when the upper portion of the iron is arranged in position. adapted to be disposcd beri-eatii the spared. oastings 2.1 within tln` base or shell 1 of the iron, said castings being suitably connected b v means of a transverse portion Mounted upon the top of the rescrvoir 1.?, is a sheet of asbcstos 23 which is securelv retained in position by means of a metal pl atc ill. the plate being retained in position by means of the U-shaped brace member the medial portion of which engages thi` upper face of the plate while the ends thereof are secured to the iujirights 10 adjacent the upper ends thereof. In this inunner. it will be apparent that the hoat from thc burner bclow the reservoir will be below the handle 1.1 so as not to interfere with the hand of the person when using the iron.

In placing the upper portion of the iron in position with respect to the base or shell 1, the spaced lugs 20 which are formed upon the rear of the plate 8 are engaged within the perforated ears 11 and the outwardly projecting lug S' at the forward end of the plate 8 is engaged within the recess 5 in the forward end of the shell and the set screw 7 is tightened against one of the up- Vrights 10 to prevent the removal of the upper portion of the shell. In order to fill the reservoir, I provide a suitable removable plug 27 which inay be quickly and readily removed to refill the reservoir when desired.

In the practical operation of my improved sad-iron, a small amount of alcohol is placed within the shell and lightecl, the upper portion of said sad-iron being tilted rearwardly, as illustrated in Fig. 1, and a U-shaped tin plate 29 is arranged above the heat so as to direct the same against the lower portion of the reservoir 13 and the supply tube 1% whereby the oil within said tube will be readily generated into gas. After the oil within the tube has been generated into gas and the burner 16 lighted, the upper portion of the iron may be replaced and the heat from the burner will generate the oil within the supply pipe into gas as fast as the oil flows into the same.

It will be noted that in forming' the openings 28 within the burner 16, I prefer to form the openings so that a series of openings will open ubstantially upon each side of the burner and the flame which issues from these openings will be directed upon the two longitudinal portions 20 of the feed pipe 14 so that the oil within the feed pipe will be readily heated and generated into gas before being supplied to the burner. After the tubes 20 have been thoroughly heated from the alcohol which was burned within the shell, the heat from the burner 16 will be sufficient to keep up the generation of gas within the tubes so that a continuous flow of gas will be supplied to the burner through the connecting pipe 17. It will be noted that when the tin plate 29 is not in use, the same may be curved slightly and engaged over the handle, the central portion being disposed beneath the handle member 11 so that all of the parts of the sad-iron may be assembled when in use and thus eliminate an accidental misplacement of any of the parts.

From the above description taken in connection with the accompanying drawings, it will be readily apparent that I have provided a simple and durable self-heating sad-iron whereby a reservoir is provided to contain a sufficient amount of fuel and wherein the contents of the reservior are gasified to maintain a sufficient heat within the base or shell of the sad-iron. It will be apparent that in the beginning of the generation of the gas by placing alcohol or other fuel within the shell, the initial heating to the shell or case will be in progress so that the base l inay be quickly and readily heated after the burner 16 has been lighted. It will be apparent that my device is extremely simple in construction and can be manufactured at a comparatively low cost.

vWhile I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions inay be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claims.

1. A device of the class described including a base, having castings mounted therein, a plate adapted for removable engagement with the base, uprights at each end of said plate, a handle secured to the upper ends of the uprights, a supply tank mounted upon the plate, and means secured to the uprights to retain the tank in position, a feed pipe connected with the tank and forming a longitudinal coil, a burner connected with the feed pipe and arranged within the coil whereby the heat from the burner' will gasify the oil before the latter passes into the burner.

2. A device of the class described including a base, having perforated ears 'at one end, a plate having lugs removably engaged with said ears and adapted to rest upon the base, spaced uprights at each end of the plate, a handle connecting the upper end of said uprights, a set screw carried by the forward end of the shell and adapted to engage one of said uprights to retain the plate upon the shell, a supply tank carried by the plate, a supply pipe connected with the tank and forming a longitudinal coil, a burner arranged between the coils and connected with the pipe, said burner being provided with openings and said openings being directed toward the longitudinal coils .whereby the flame may the oil therein.

A device of the classdescribed including a hollow base member, a plate removably mounted upon the upper edges thereof, a tank carried by the plate, a burner disposed beneath said tank and adapted tobc arranged within the base, and a feed pipe connected with the tank and forming a longitudinal coil arranged upon opposite sides of the burner whereby the heat from the burner will gasify the oil before the latter passes into the burner.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
