PATENT OFFICE.

SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 743,897, dated November 10, 1903.

Application filed February 13, 1903. Serial No. 143,207. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS OowLYN Low- THORP, a citizen of the United States, residing at Trenton, county of Mercer, State of New Jersey, have invented certain new and useful Improvements in Sad-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.

Theinvention relates to sad-irons of all sizes-as, for instance, the smaller and lighter kinds for domestic use and for ordinary laundry work or the larger and heavier pressingirons used in tailors shops and the like.

The invention relates principally to the shape or configuration of the surface against which the flame impinges, said surface being inclined on both sides from a central projecting ridge, whereby in practice the products of combustion and the flame have a tendency to follow closely the inclined surfaces to the great advantage of the heating operation.

In the drawings, Figure 1 represents a longitudinal section and partial elevation of a sad-iron embodying the invention. Fig. 2 represents a transverse central section thereof.

Similar letters of reference indicate similar parts in both views.

Referring to the drawings, it will be noted that the main body portion of the sad-iron consists of a single casting of steel or iron cored out centrally and provided with the airsupply openings 01.

In casting the main body portion a baked sand-core is employed, conforming in shape to the proposed configuration of the hollow interior. This core-is inserted within the outer or pouring mold, (provision being made for casting the apertures a in the sides,) and the metal is then poured, whereupon after cooling the core may be broken'up by some pointed instrumentinserted through the apertures and may be thus removed. n

In the form of sad-iron shown the main body portion is provided with two ironingsurfaces at e and is so arranged that it may be reversed or turned over to use one surface while the other is being reheated. The holes or slots of the gas-burner tube 0 are preferably so arranged that the greater amount of gas will be burned at the top openings of the heating operation.

The burner-tube is provided with the usual air-inlet opening f and also with the usual gas-jet injector. (Indicated in dotted lines in Fig. l.) The tube may be conveniently, but removably, held in place by a hook it, pivoted to the handle.

The handle itself is made up of two metal bail portions Z-m, havingalap-joint, as shown, whereby they may be inserted in the hollow wooden hand-grasp B, whereupon they may be secured therein by means of screws n or in any other convenient manner. This constrnction also permits the asbestos shield G to be inserted and held in place to protect the hand of the operator from radiations of heat.

. The devices for locking the handle to the iron or releasing the latter, so that it may be reversed, are clearly shown and consist of the locking-pin r, adapted to engage with one of two similar recesses sand operated by the spring-pressed lever A, it being evident that thu nib-pressu re applied to the free end of the lever will disengage the pin from its recess, therebypermitting the main body portion of the sad-iron to be revolved until the pin engages the opposite recess.

Having thus described my invention, what I claim is 1. A'sad-iron having a metal main body portion with a hollow interior, said interior being provided with a central longitudinal ridge, with inclines extending to the opposite sides of said interior and terminating in londisposed gas-burner tube, and centrally-disposed longitudinal ridges between which the burner-tube is located, said ridges having inclines extending to the opposite sides of the interior and terminatingin longitudinal pockets thereat; substantially as described.

3. A sad-iron, having a metal main body portion with a hollow interior, a centrallydisposed gas-burner tube, and centrally-disposed longitudinal ridges between which the burner-tube is located, said ridges having inclines extending to the opposite sides of the interiorand terminating in longitudinal pockets thereat, said sides being provided with open-work apertures betweenthe pockets formed by the meeting of the sides and inclines; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANCIS OOWLYN LOWTIIORP.
