Specification forming part of Letters Patent No. 184,881, dated November 28, 1876; application filed September 9, 1876.

To all whom it may concern:

Be it known that I, MICHAEL MAHONY, of Troy, in the county'of Rensselaer and State of New York, have invented certain new and useful Improvements in Sad-Irons; and that'the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents, in perspective, with the face upward, one of my improved smoothing sad-irons. Fig. 2 represents,` in plan, the face of one of my improved polishing sad.- irons. Fig. 3 represents a longitudinal vertical section through the center of Fig. 2.

, Similar letters of reference, where they occur, denote like parts of the sad-irons in all the figures.

Ordinary smooth-faced sad-irons have been used for years upon linen, &c., to smooth it down and improve its appearance; but with such sad-irons it is very difficult to produce the gloss or polish that is so much in demand, as it requires a pressure thatcan he produced but by very few persons. To accomplish the result polishing sad-irons have been made with the face so reduced in size that, Withl an ordinary pressure, a person could produce the desired result, but also with the expenditure of much time.

To remedy this defect is the object of my invention, which relates mainly to sad-irons kfor housekeepers or laundry purposes; and

it consists in the formation of indentations or projections arranged after certain configurations upon the face of the sad-iron, so that the pressure applied upon it will be condensed upon a smaller surface than if the sad-iron were smooth and on an even plane upon the whole surface; and my invention consists also in arranging theindentations or corresponding pro` jections upon the sad-iron, so that the smooth projecting surfaces Will form triangles or polygons, with their diameter parallel or per! pendicular to the center line of the sad-iron. It consists also in having the edge of each projection .rounded off or buffed, to produce, while being used, a perfectly smooth and polished surface upon linen or other material.

To enable others skilled in the art to make and use my invention, I will -proceed to describe the same with reference to the drawlngs. 4

A represents a sad-iron, made in any suitable shape, upon the face of which indentations a, are formed, so as to leave ridges or projections b to rest and press upon the material that is to be smoothed down or polished.

In Fig. 1 is shown a sad-iron of the form most commonly in use, B representing the handle. The indentations a upon its face are surrounded by a continuous smooth-faced rim, c, upon the same level with the topof the ridges b, so that in passing the sad-iron upon linen, &c., the ridges-or projections b will not catch into the material and destroy the effect that it is intended to produce; and, for the same reason, the Whole face of the iron-viz., the top of the ridges-after having been faced upon an even plane, are buffed with soft leather and emery. to take off the sharp edges of the ridges.

In the polishing-iron ,shown in Figs. 2 and 3, there is no smooth-faced rim shown, as its face is slightly spherical, and formed into ridges b and indentations a. The edges of this sad-iron do not impinge upon the linen when in use, as it is only slightly chamfered at the edge d to prevent any accidental abrasion.

After many experiments upon various configurations of ridges or indentations-elliptical, circular, wavy, star-shaped, &c.-I found that the form giving the best results should form an angle the bisecting line of which is parallel with the line of direction in which the sad-iron is advanced upon the material, so that each small angular ridge will act as the point of a sad-iron -to open out and smooth any crease that may be upon linen, 85e.

It is evident that the ridges formed upon the face of a solid sad-iron could also be made by having metallic plates perforated in any l desired configuration, and be used either as a shoe fora smoothfaced sad-iron, or for a hollow sad-iron, without departing from the spirit of my invention. g

`What I claim as new, and desire to secure by Letters P atent, is- `l 1.v A sad-iron having its smoothing face formed into indentations and projections, arranged after'certainV configurations, so that the pressure applied upon the sad-iron will be received upon said projections, substantially as and 'for the purpose described.

2. In a flat-iron, the indentations or corresponding .projections arranged upon the face of a sad-iron so that the smooth projecting surfaces will form triangles or polygons, with their diameters parallel or perpendicular to the center line of the sad-iron, substantially as and for the purpose described.

3. A flat-iron having an indented surface, with the edge of each projection or indentation rounded off or buffed, to produce, while being used, a perfectly smooth and polished surface, substantially as described.
