FLAT-IRON.

SPECIFICATION forming part of- Letters Patent No. 230,641, dated August 3, 1880.

Application filed June 6, 1,879.

To all whom it may concern:

Be it known that we, CREMORA F. MCCARTY and WILLIAM MCCARTY, both of Boston, in

the county of Suffolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Flat-Irons, &c., of which the following is a specitication.

Our invention relates to tlatlirons and similar devices for smoothing and pressing seams and fabrics, especially to those designed to be heated internally byllame, and to the apparatus for heating' the same, and are designed and found by actual use by ns to overcome eertain diflculties and imperfections heretofore existing in such devices, and also to go farther and make a tailors goose as practically and successfully heated by dame of a lamp as other and smaller irons have been. The nature of these improvements will be apparent from the followingdescription,taken in connection with the drawings, in which- 'Figure l represents a vertical section through a goose (in the plane of its handle) and lamp and holder in position for heating, and embodying our improvelnents in one form; and Fig. 2 represents, in a vertical section at right angles to the other, the same apparatus, both sections being through the center.

In these drawings, A is a tailors goose or large and heavy flat-iron, having an internal cavity, B, and an opening, a, at the top, with its base or rear end downward. C is a lamp of any convenient form, but which we usually make long and low and with a water compartment or tank thereon to keep it cool and safe, and which has the wicktubes or simple burners D D. H is a holder or stand, having a table or flat part to receive the base of the iron, legs to support it at a suitable height, and, as we generally make it, with lugs or keeps projecting upward from the table or flat part to adjust and hold the iron iii position. The tlat part of the holder is made open, so as to admit of the air passing freely upward through it and around the wick-tubes, and may be made in skeleton, with a piece of perforated sheet metal, .1, on it for the iron to rest on, and which the tubes D D may pass up through. K is a base or flat frame which supvbe adverted to-viz., to utilize all the heat pro- 6o i duced by the vflame as far as possible, to increase the heating capacity, and economy of construction; and these objects are to be attained by preserving complete combustion of the llame at the same time, so as to avoid smokiness, 85e. The object of securing stability and adjustment of a heavier iron is attained by the holding device already described.

One difculty hitherto found with this class of devices was the impracticability of bring- 7o ing the flame up into the' iron far enough to allow the latter to take all the heat. Another was that the tailors goose, which often weighs twenty-live pounds or more, would not heat quickly and suflciently with one flame or one burner, and merely bringing two common burners together at or in the base of the iron would result in the running together of the flames into one of imperfect combustion, and the opening in the iron must also be larger, 8o which allows of too much cooling of the iron in the use of it; and another difficulty was the expensiveness ot' a complex burner with dome to collect the flame and the added fact that with a large lamp and iron and strong heat this dome burns out and melts down. These and other difficulties are overcome and p results hitherto unattained are reached by the following features and modifications in our contrivance: We make the burner D simple 9o and strong in the parts connected with the lamp, and so as to reach just within the base of the {lat-iron when in position for heating, and we make the rest of it in the base of the iron, o being a rounded cavity about the tube D, defined by the ledge or projection l, which divides the cavity o from the cavity B, the latter being shaped for and operating as a chimney, and the former as a cone or, dome to collect and direct the dratt and flame, thus completing the burner.

P is a partition or standing wall within the goose and having the ledge Z continued along it oneither side, and which separates the flames and drafts, where two or more burners are desired, fora sufiicient distance upward to allow ol complete combustion. 7e usually make the cavities o about an inch in height, and the partition P about one-fourth or one-fifth the height ot' the iron.

It is desirable, we find, in these hollow irons to have the openings at either end as small as possible to prevent too muchv current of' cold air in using them, and we find by experiment that this arrangement of the partition is better than carrying it entirely through. The ledges Z, with the prolierly-shaped cavities above and below, as well as the partition P, can be cast. in theiron with no appreciable increase in diticnlty or cost; and the contrivance so made, even with a single burner, is much more eifectivc, durable, and economical, while with two burners, as shown in Fig. l, a goose of tifteen pounds weight can be heated in fifteen minutes without danger or destruction of the lamp to a degree impossible with any contrivance we know of.

The perforated sheetwis shown in the drawings as below the support ot' the goose; but when we have it in operation we place it above, and so that the base of the goose rests on it.

We do not claim any novelty or invention in the form of the lamp apart from the burner,

nor in the suggested arrangement of a watertank thereon, nor in the perforated sheet w, or its position when in use, these being incidental and well-known parts ot' related devices.'

Te claim as new and of our inven tionl. A hollow flat-iron adapted to be heated by flame, constructed with a ledge, l, so formed inward as to bound and combine with the cavities o, of, and B, substantially as and for the purposes set forth.

2. The described goose or Hat-iron, adapted to be used with a lamp for heating, consisting internally of the cavity B, opening a, cavities 0 o', and ledges Z l, and the partition P.

3. rlhe cone or dome o for a wick-tube, D, 5o

cast or made in and continuous with the Inetallic base ot' a hollow Hat-iron or tailors goose adapted to be heated by tlame from such wick-tube, said dome 0 being constructed with acontraction, as at Z, so as to gather and di- `5 5 rect the air-current about the Haine, and to operate as and take the place of the usual dome ot the burner, ot' which the wicktube D is a part, substantially as set forth.

4. In a hollow Hat-iron or tailors goose adapt- 6o ed to be combined with a wick-tube and heated by flame, a partition, P, and openings 0, o', and u, constructed and arranged substantially as shown and described.
