PERRY AUGUSTUS HULWIOK, OF GOSHEN, INDIANA.

SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 574,685, dated January 5, 1897.

Application filed July 12,1895. Serial No. 555,782. (No model.) I

To all whont if; may concern:-

Be it known that I, PERRY AUGUSTUS HUL- WIGK, a citizen of the United States, residing at Goshen, in the county of Elkhart and State of Indiana, have invented a new and useful Sad-Iron, of which the following is a specification.

My invention relates to sad-irons, and has for'its object to provide a self-heating sadiron provided with a fuel-reservoir exposed 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 simple and efficient arrangement of parts whereby the burner may be replaced when desired or necessary and is secured firmly in position when in use.

Further objects and advantages of this invent-ion will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a sad-iron constructed in accordance with my invention. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a bottom plan view of the deflecting-plate, showing the vaporizing pipe and injector in operative position. the base or shell of the iron detached. Fig. 5 is a detail view of the burner detached. Fig. 6 is a similar view of a slightly-modified form of burner.

Similar numerals of reference indicate corresponding partsin all the figures of the drawings.

1 designates the base or shell of the iron, provided with a cavity forming a combustionchamber, suitable openings 2 being formed in the sides of the combustion-chamber to supply the necessary amount of air to support combustion. In this combustion-chamber, near the front end of the iron, is formed a parallel-sided seat 3, and in alinement therewith, near the rear end of the iron, is a similar seat 4, the sides of which are extended up to the plane of the upper edges of the sides of the shell. In rear of the seat 4is a rest 5, having a curved upper surface.

Fig. 4 is a perspective view of The burner isprovid ed at its front end with aparallel-sided lug 6 to fit in the seat 3, and at its rear end with a tubular projection or throat 7 to lit in the seat 4, the ends of the burnertube bearing against the facing sides of the lugs, in which said seats are formed to prevent endwise displacement thereof. The burner'is hollow and may be bored or provided with perforations 9, as shown in Fig. 5, or transversely sawed to form kerfs 10, as shown in Fig. 6. Arranged upon the base or shell coverin g the combustion-chamber is a deflectingplate 11, which thus closes the top of the combustion-chamber and is exposed to the flame produced at the burner, and resting upon said deflecting-plate with its lower side spaced from or out of contact with the upper surface of said plate, is the hollow heat-guard and reservoir 12, said guard and reservoir being held at the desired interval from the surface of the deflecting-plate by means of spacing-blocks or projections 13 on the upper surface of said plate. Communicating with the interior of the guard and reservoir is a fuel-inlet opening 14, fitted with a screw-plug 15, and also communicating with the interior of said guard and reservoir at its lower side, and contiguous to the front end thereof, is a pipe or conductor 16, having an elbow, of which one arm extends upward through an opening in the deflecting-plate. This pipe or conductor is arranged within the combustion chamber and extends approximately parallel with the burner-tube to and through the rear end of said combustion-chamber, which is cut away to form an opening for its passage. The rear end of this pipe or conductor communicates with an injector 17, having a needle-valve 18, the injector being adapted to discharge the fuel either in a liquid or gaseous state into the throat at the rear end of the burnertube. The valve is controlled by means of the hand-wheel 19, arranged at the rear end of the iron, and the guard and deflectingplate are secured to the shell or base by means of vertical screws or bolts 20, said guard carrying a handle 21.

The injector bears upon the rest in rear of the seat 4, and it is held in contact with said rest by means of a retaining-lug 22, depending from the rear end of the deflecting-plate.

In advance of said retaining-lug and also depending from the deflecting-plate is a stud 23, equal in width with the interval between the sidesof the seat 4 and adapted to bear at its lower end upon the upper side of the tubular projection or mouth of the burner tube, whereby the burner-tube is securely fastened in position and held from displacement.

From the above description it will be seen that the fuel after leaving the reservoir, where it is heated to a certain extent by the radiation from the deflecting-plate, passes through the pipe or conductor arranged in the combustion-chamber, where it is exposed to the heat from the burner, and is thereby vaporized. The vaporized fuel is discharged by the injector into the rear end of the burnertube and there is ignited, and the flame is projected against the lower surface of the defleeting-plate. It will be seen, furthermore, that the guard and reservoir which is interposed between the defiecting-plate and the handle serves to protect the hand of the oporator and avoid exposure to the direct radiant heat of the iron.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is 1. In a sad-iron, the combination of a hollow open-topped base forming a combustionchamber, alined front and rear seats having open upper sides arranged in the combustionchamber, a burner-tube removably fitted at its reduced extremities in said seats, the ends of the body portion of the burner bearing against said seats to prevent longitudinal dis placement, a plate detachably secured to the base to close the upper side of the combustion-chamber, a stud depending from said plate within the chamber to bear upon the burner and hold it in its seats, a reservoir and handle carried by the said detachable plate, and an injector in communication with and 1 carried by the reservoir to discharge fuel into. the burner-tube, substantially as specified.

2. In a sad-iron, the combination of a hollow base forming a combustion-chamber and provided with a front parallel-sided seat 3 and a rear seat 4 in alinement with the front seat, a burner-tube provided at its front end with a flat parallel-sided projection 6 to fit in the parallel sided seat 3 and provided at its rear end with a hollow projection forming a throat and adapted to fit in the seat 4:, a plate detachably secured to the base to close the upper side of the combustion-chamber and provided with a depending stud to bear upon the upper side of the hollow projection of the burner and prevent vertical displacement thereof, a reservoir and a handle carried by the said detachable plate, and an injector carried by and in communication with the reservoir and arranged in alinement With the throat of the burner-tube, substantially as specified.

3. In a sad-iron, the combination of a hollow base or shell provided with front and rear seats and a rest in rear of the rear seat, a burner-tube provided with terminal projections fitted in said seats, one of said projections being hollow to form a throat, a deflecting-plate covering the cavity of the base or shell, a hollow guard and reservoir arranged above the deflecting-plate and carrying a handle, and an injector connected to a pipe or conductor in communication with the reservoir and adapted to discharge fuel into the throat of the burner-tube, said injector being arranged upon the rest in rear of the rear seat and the deflecting-plate being provided with a depending lug to bear upon said injector and hold it in place on the rest, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
