SMOOTHING AND POLISHING IRON.

SPECIFICATION forming part of Letters Patent No. 350,759, dated October 12, 1886.

Application filed February 2, 1886. Serial No. 190,502. (No model.)

To all whom it may concern.-

Be it known that I, J osErH B. MoFALL, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Smoothing and Polishing Irons and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification,

and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a longitudinal section of my invention, and Fig. 2 a crosssection thereof.

The present i nvenlion has relation to certain new and useful improvements in that class of smoothing and polishing irons in which the body is formed hollow and provided with a removable heating-core, the body having a detachable top and handle and a latch device for securing the top in place.

The object of the invention is to render more effective the above-mentioned class of irons whereby the necessary amount of heat is obtained where most needed without danger of burning the goods with which it comesin contact, the heat being generated on the inside of the body of the iron and consumed at the face thereof, as will be hereinafter described and claimed.

In the accompanying drawings, A represents the body of the iron, formed hollow, as shown, and having double walls around its sides and ends, between which is placed a fill ing, a, of plaster-of-paris or other heat non-conducting material. Vithin the body Ais placed the heated core B, said core being concave upon its under side to form a heat-storing chamber and equalizing the heat over the face of theiron, as all heated bodies are hotter or give off a stronger force of heat at the center than at the surface, and without this construction thei'ace oft'he iron would be hotteriu the center than at the surface.

Suitable lugs, b, may be formed on the bottom of the body A to fit in corresponding depressions in the core B, to hold it stationary and in place when the iron is in use, and the core is cast with an inclined orifice, c, to receive the end of a lifter for removing it from the fire and placing itin the body of the iron. The top of the body A consists of three plates, 0 D E, and between these plates are two non-conductors of heat-via, a confined air-space, (Z, and a filling, e, of plaster-of-paris,

tends around the sides and ends of the body 6 A, retracts the heat, and prevents it from passingout through the outer wallandbeing lost and wasted. As the heat generates in the body A it passes upward and is met by the lower plate,

Therefore I provide an inner 6o O, which becomes equal in temperature with the core B; but immediately above this plate the heat is met by the refractory nonconducting filling e, above which is the plate D, and above this a layer of confined air in the space (I, to prevent the heat from passing into the top of the iron or upper plate, E.

The heating-coreB is supported off the bottom of the iron by lugs Z), hereinbefore described, fitting into depressions in the core and the concave face thereof, together with the space formed by supporting it off the bottom of the iron forms the heating-chamber, a perfect heat-storing chamber being also provided at the sides and top of the core.

To the top plate of the cover, or the top of the body A, is suitably attached ahandle, F, by screw-bolts h and nuts i, or any preferred fastening may be used, the bolts passing through the plates 0 D, and by means of the nuts the plates are held together. at its rear end, is formed with a catch, is, which extends under a flange, Z, on the inner walhf, and the opposite end of the plate is depressed to form a seat and support for a sliding bolt,

The lower plate, 0, 0

G, operated by a thumblever, H, and spring m. The lever II is pivoted to the' shank of the handle F, its lower end engaging with a notch, n, in the rear end of the bolt G, said bolt having a stop, 0, to prevent it from being drawn back too far when releasing it from too engagement with the flange p. Thestop 0 also formsa guide for the bolt,as when it is drawn back it enters a slot, 1-, in the bolt seat or sup- I port Iand guides it in its sliding motion, the spring m forcing the bolt back to its normal position when pressure is released from the lever H. l

The bolt G at its forward end and'upon its underside is beveled, as shown at s, and the end of the flange 19 also beveled, so that the bolt will be acted upon automatically by coming in contact with the edge of the flange p, thereby attaching the cover or top of the body A without using the leverI-I to draw the bolt back, this being only necessary when removing the top or cover.

An iron constructed in accordance with my invention is perfectly insulated; consequently the heat is prevented from escaping at the sides and at the top by the double insulation, which effectually accomplishes the object sought. The heat-storing chamber formed by the concavityin the under side of the heating- 30 itself being essential in a core-heating iron.

By the depression of the lower plate, 0, of

thickness or height in every direction from a central point of the core, as and for the purpose set forth.

2. The combination, with the hollow body and top or cover, of a core having a concaved lower face supported within the body, leaving a space between it and the top, bottom, sides, and ends of the body, the space between the upper side of the bottom of the body and the concaved face of the core gradually diminishing toward the ends and sides of the body, substantially as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOSEPH B. MoFALL.
