T 0 all whom it may concern:

Be it known that we, BENJAMIN. Scrum)- LER and JACOB Goaoon VInR'rnL, citizens of the United States, and residents of F reeport, L. 1., county of Nassau, and State of New York, have invented certain new and useful Improvements in Puff- Irons, of which the following is a specification.

Our improvements relate to fabrlc heatmg and smoothing devices, known to the trade as puff irons, in which the material to be treated is drawn over a heated convex contactual surface which performs the double function of a support as well as of means whereby the goods may be mampulated to attain the desired effects without sub ect1ng the same to pressure on both sides thereof; and our invention has for its mam ob ects the heating of such an implement effectually by electricity; the provision of means whereby ironing heads of different sizes and shapes may be readily substltuted for each other according to the varying requlrements of use; and the adaptation of the device for convenient installation wherever electrical circuits are available, all as hereinafter fully set forth and claimed speclfically.

In the accompanylng drawlngs,

Figure 1, is a central vertical sectional elevation of a puff iron embodymg the essential features of our invention;

Fig. 2, is a top view of the 1ron1ng head shown in Fig. 1; and

Fig. 3, is a cross section thereof taken upon plane of line 3-3, Fig. 2. l

S, is a tubular standard formed with a relatively broad base S to aiford adequate support for the convex 1ron1ng head H, under the stress of use. The base S, is formed with a recess or sleeve 8, in which is positioned a bushin b, of any suitable insulating material. mbedded in the insulating bushing b, are two metallic sockets e, e, for the reception of the terminal plugs p, p, of wires w, w, forming part of an electric circuit.

The plug sockets e, e, are connected electrically by copper or other suitable wire conductors c, c, with binding posts (1, d, secured to the lower portion of another bushing 12', of insulating material fitting tightly or otherwise secured in position in the upper end of the standard S. This upper bushmg 6', is formed with two vertical recesses 5 b lnto which the upper ends of the binding posts d, d, protrude as shown in Fig. l, PIOJGCtlIlg sufiiciently above the bottom of the bushlng of insulating material to form contacts for electrical engagement with the lower ends of the terminal rods 1", r, of the resistance coil R, which constitutes heating element. The ends of the coil R, are 'of course electrically connected to the upper ends of the terminal rods 7*, r, by suitable means, as by binding nuts r, r, or equivalent expedients.

This relatively fiat resistance coil R, formed of suitable metallic wire is embedded 1n a layer M, of mica, asbestos, or other suitable refractory insulating material, which is confined between the convexo-concave face plate 71., of the head H, and the clamping plate K, thereunder by means of nuts 70, 70, on the assembly bolts A, A,the threaded upper ends of which latter engage with female screw threads formed for their reception in the concave under side of said face plate It, and said bolts A, A, extending through both the clamping plate K, and the back plate h, of the head, and being threaded not only for engagement with the aforesaid clamping nuts 7c, is, but also for engagement with the nuts 11, a, Which secure the back plate in, in position. Thus the two assembly bolts A, A, with their nuts 70, 7c, and n, n, afford means whereby the three main parts of the head (the face plate, heating element M, R, and back plate It) may be effectually secured together in a simple manner, thereby reducing cost of manufacture to a minimum while insurin a rigid unitary structure of ironing hea which is especially desirable in this case because we purposely make the ironing head H, easily detachable from the standard S, and contemplate the provision and use with each standard S, of a pluralit of ironing heads H, of different shapes an sizes adapted to the varying requirements of the dissimilar kinds or shapes of goods to be treated.

To this end we support the coil terminal rods 1', '7', in a block F, of insulating fiber or other suitable insulating material, which is securedin position by and between flanges on the clamping plate K, and the back plate (13', by the nuts 11, n, as will be understood by reference particularly to Fig. 1, of the drawings. Thus held and centralized, the terminal rods 1, r, are in alinement with the inner, upper ends of the binding posts (Z, d, which protrude into the recesses 6 b in the upper insulating bushing b, as hereinbefore stated. Hence, when the ironing head H, is lifted from the standard S, contact between the coil terminal rods 1, r, and the circuit terminal posts (Z, d, is broken automatically without any disconnection of parts other than that suilicient to release the head from rigid engagement with the top of the standard. Although we do not wish to limit ourselves in this respect to the identical structure shown, we prefer to effect the temporary union between head H, and standard S, by forming the back plate with a socket sleeve 71?. which fits over the upper end of the standard S,said socket sleeve 71 having an internal shoulder 71". which rests upon the top of the standard S, and the back plate h, and its sleeve being attached to the standard S, by means of a thumb screw t, or equivalent mechanical expedient easy to manipulate.

Thus, by simply loosening the thumb screw 2 the head H, may be immediately detached from the standard S, by simply lifting it off the latter, without otherwise disconnecting parts. terminals, or wires; and the ironing head H, or another like 1t in structure, but different in external configuration, may be as quickly and easily mounted on the standard, ready for immediate use, without connecting up parts other than to tighten the thumb screw 1, the coil terminal rods 1, 7', automatically contacting with the circuit terminal posts (I, (I. when the head is lowered into position upon the upper end of the standard S.

This feature of providing for the convenient and expeditious substitution or replacement of ironing heads on the standard is an important feature of our invention since it enables us to provide each electrical installation e.,each standard S,interposed in a suitable electric circuit) with a set or plurality of ironing heads each specially adapted to the treatment and manipulation of a particular shape or class of goods. garments or materials,-a practical advantage where puff irons are used, especially in establishments where economy of space is a desideratum, or where facilities for electric installation are restricted.

And another feature of import is the ease with which such installation may be effected in the case of our device,it being simply necessary to insert the electric circuit terminal plugs 11, p, into the sockets c, e, in the base plate S, of the standard S, in order to effect this result.

By embedding the resistance coil R, in a layer of refractory material such as mica,

asbestos, or the like, we effectually insulate the coils from each other while applying the full value of the heat generated directly against and to the face plate at an even temperature throughout the whole extent thereof.

In our concurrent application Serial No. 306,999, filed June 26, 1919, we show and describe a puff iron of the same type as that disclosed herein but embodying features not herein contained nor claimed.
