SAD-IRON.

Specicaton of Letters Patent.

Application filed February 2, 1912.

Patented Nov. 19, 1912.

Serial No. 674,899.

To all whom 'it may concern.'

Be it known that I, LOUIS ROSENBAUM, a

citizen of the United States, residing at the f city of New York, borough of Manhattan, State of New York, have' invented a certain new and useful Improvement in Sad- Irons, of which the following is a specication, reference being had to the accompanying drawings, forming a part hereof, in which- I Figure l is a side elevational view of a sad-iron embodying my invention; Fig. 2 is a rear elevational view of the same; Fig. 3 is a longitudinal sectional view through the same; Fig. 4 is a transverse sectional view through the same; Fig. 5 is a top plan view; Fig. 6 is a top plan view, on a reduced scale, of the lower or baserasting; and Fig.

7 is a top plan view, partly broken away, of a slightly modiiied form of sad-iron ernbodying my invention.

This invention relates to a certain newl and useful improvement in sad-irons and particularly to that class of sad-irons wherein a combustible fluid is used as the.

heating medium.

Heretofore sad-irons of the class stated,

commonly called gas-irons, have generally,4

so far as I am aware, been made-up or constructed of a more or less large number of individual or distinct parts connected or secured together 1n various ways; 1t has been found, however, that the cost of production of such irons is comparatively heavy and that they more or less quickly get out of good working order.

The objects of my present invention are to provide a sad-iron of the kind stated which has but few, practically the minimum number of, separate parts, and thereby reduce materially the number of joints and practically to a minimum the lia-` ment, and combination of the several parts of my new sad-iron, all as will hereinafter be described and afterward pointed out in the claims.

As shown in the accompanying drawings, wherein like reference characters refer to like parts throughout the several views, my new iron comprises preferably but two separate castingsa lower or bodyportion or base-casting, as I will call it, A, and an upper or handle-portion casting, as it might be termed, B.

The lower or body-portion A is preferably a hollow metallic casting having a bottom wall l of any suitable thickness, flat on its outer' or ironing surface, preferably longitudinally corrugated or grooved on its inner surface, as at la, and preferably pointed at its forward end, as at 1b, and having the shape in plan elevation of the usual iron. Base-casting A at its rea-r is also preferably cut away or provided with an opening, as at 2, and with a pair of i11- wardly-disposed or projecting shoulders 2a, the greater part of its top wall being also preferably cut-away, as at 3, continuously with said opening or cut-away portion 2 in the rea-r wall thereof, as shown particularly in Fig. 6 and for purposes hereinafter more fully appearing.

The sidewall of casting A preferably comprises, as shown particularly in Fig. 4, portions 4 and 5. Portion 4 extends preferably and substantially perpendicularly upwardly from the outer edge of bottom wall l, while portion 5, which lies within the area of portion 4, extends convergingly or obliquely upwardly therefrom and is preferably integrally connected at its lower end to the upper end of portion 4 by means of a web or the like 6 having preferably a curved outer surface or face, as shown. Web-portion 6 is also preferably cut-away, as shown, to provide a series of elongated draft-openings or slots 7 around said base-casting, while depending from said side-wall-portion 5 is a series of flat vertically-disposed aprons or curtains 8 substantially parallel with said side-wall-portion 4 and coincident, respectively, with said slots 7 whereby, as it might be said, said slots 7 open or lead directly upwardly from the interior of casting A. At thepforward end lb of casting A, said web-portion 6 is preferably further provided with a draft-opening 9, and at the forward end of casting A, said side-wall-portion 5 is also preferably provided adjacent the upper end thereof with a pair of oppositely-disposed draft-openings 10, as .shown particularly in Figs. 1, 3, and 4. In its top and at the forward end thereof, casting A 1s also preferably provided with an enlarged draft-opening 11 separated from said cutaway portion 3 by means of a bridge-portion 12, as shown particularly in Fig. 6, upon which bridge-portion 12 is preferably integrally formed an upstanding threaded boss 18, for purposes hereinafter more fully appearing. Projecting upwardly from, and preferably integral with, said side-wall-portion 5 is a portion 14 which extends substantially completely along one, preferably the left-hand, side of casting A and for a short distance, and at the forward end of the iron, on the right-hand side thereof, said portion 14 being preferably thickened at its rearward and forward ends, as at 15 and 16, respectively, and cut-away at the forward part of casting A and on opposite sides thereof, as at 17, as shown particularly in Figs. 1, 3, and 4. At its right-hand upper rear end, said side-wall-portion 5 is also provided with an upstanding portion or handle-support 18, the upper face of said support 18 being on the same horizontal plane with the upper face of said portion 14, as shown particularly in Figs. 1 and 2. As shown particularly in Fig. 2, the base or lower side of the open or cut-away rear end wall of casting A is preferably corrugated or scalloped, as at 19. Upper or handle-portion casting B comprises a handle-plate 2O adapted to extend completely over the top of casting A and to rest upon said upwardly-projecting handle-supporting portion 14 and said handle-support 18, as shown particularly in Fig. 1. Extending upwardly at one, preferably the forward, end of, and preferably cast integrally with, handle-plate 20, is a handlearm 21; and extending somewhat obliquely upwardly and rearwardly from said handleplate 20 at its other, or rear, end, and also preferably cast integrally therewith, is what I term a hot air and gas reservoir or chamber 22 provided in its upper end, as at 22, with a combustible fluid supply opening and fully described in United States Letters Patent No. 904,087, granted to me November 17, 1908. Extending upwardly and inwardly from and adjacent the upper end of, and

also preferablyr cast integrally with, saidreservoir or chamber 22, and in proper alinement with the upper end or portion of handle-arm 21, isa short handle-arm 23, the upper ends of said handle-

arms

21 and 23 being oppositely cut-away or recessed or provided with oppositely-disposed horizontal slots 21'l1 and 23a, respectively, for receiving and holding a through-bolt 24 adapted to support a suitable handle 25, as shown particularly in Figs. 1 and 3. On its under side and communicating with said reservoir or chamber 22, said handle-plate 2O is integrally provided with a throat or neck portion 26 leading into, and integral with, an elongated hollow burner 27 extending substantially parallel with handle-plate 20 and having on its under face a plurality of `jetperforations or openings 27a, burner 27 being adapted to fit longitudinally within casting A and of a length as to extend from the rear end of casting A to closely adjacent the forward end thereof, as shown particularly in Fig. 3.

As shown particularly in Fig. 3, said throat or neck-portion 26 is preferably gradually enlarged or flares outwardly from said handle-plate 20 toward its mouth or toward said burner 27, the frontwall thereof being preferably obliquely-disposed or curving gently forwardly relatively to handleplate 20, whereby there is provided a gradually increasing passage for, and one free from any sharp anglesor projections which might interfere with or impede, the flow of the combustible fluid from chamber 22 to burner 27. The rear end of burner 27 is integrally provided with, and closed by, a flat or plate portion 28 having a shape substantially as shown in Fig. 2 adapted to fit in, and to the greater extent close, the open rear end of casting A, and toengage with said shoulders 2a, said corrugations or scallops 19 therebeneath providing further draft-openings into the interior of casting A. A hand-guard 29 of any suitable material is preferably arranged above handle-plate 2() and between handle-

arms

21 and 28 with its opposite ends secured, as shown, on said through-bolt 24. In operatively assembling said castings A and B, casting B is first placed at the rear end of casting A with burner 27 directed into the interior of casting A and the forward end of handle-plate 2O slightly above, or resting upon. said support 18 and thickened portion 15 of said portion 14, and is then slidablymoved forwardly on, or relatively to, casting A until said plate or flat portion 28 fits neatly in, and substantially flush with, the rear end of casting A. 1When in such position, the forward portion of burner 27 will lie beneath said bridge portion 12 and said plate 28 will engage with said shoulders 2ZL and said castings A and B be thereby loosely held together, and whereby also said castings A and B may now, in the preferred form of my new iron, be firmly fastened or securedV together by means of a single screw or thelike 30 passing through handle-plate 2O into said threaded boss 18. 1t will be noted that said cut-away portion 3 in the' top wall' of casting A provides a space adapted to permit free movement of said throat or neck portion 26 when the said castings are being operatively assembled, and which is, for the Y space between said handle-support 18 and the thickened forward end 16 of said portion 14 provide escape passages to the exterior for the products of combustion arising from the interior of casting A through said top opening 11 and cut-away portion 3.

By corrugating or grooving the inner face of bottom wall 1 of casting A, I am enabled to present to the flame of the heating medium or combustible fluid nearly twice the area of heating surface that is obtained with a flat face. The iron being usually grasped and manipulated by the righthand of the user, it will be seen that said upwardly-projecting portion 14 prevents the products of combustion arising from casting A coming directly in contact with the clothes of the user. This portion 14 may, of course, be cast on the right-hand side of casting A for left-hand users. The said elongated slots 7 and also said draft-openings 9 and 10 provide means for a plentiful supply of air topromote practically perfect combustion of the combustible fluid supplied to the burner; and it will be noted that said curtains or aprons 8 absolutely prevent any escape laterally of the flame or products of combustion of the burning combustible fluid, to the possible injury of the user of the iron or the goods being operated upon.

I have found my new iron to be highly eflicient in operation, and from the foregoing it will be seen that mynew ironcomprises but two, practically the minimum number of, castings, and that the same may be quickly and easily operatively assembled and secured together and will not readily get out of good working order.

In Fig. 7 I have shown a slightly modified form of sad-iron embodying my invention. In this form, instead of providing casting A with a single boss 13, l provide the same with a plurality of such bosses and removably secure castings A and B operably together by a plurality of screws 30, handle-plate 20 being preferably cut-away or recessed, as shown, on its opposite sides, as at 20, for receiving said screws. Y l am aware that minor changes in the construction, arrangement, and combination of the-several parts of my new iron might be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
