PUFF-IRON.

Specification of Letters Patent.

Patented Dec. '7, 1920.

Application filed June 26, 1919. Serial No. 306,999.

To all w ham it may concern Be it known that we, BENJAMIN SoniND- LER and JACOB GORDON VIERTEL, citizens of the United States, and residents of Freeport, 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 fabric heating 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 manipulated to attain. the desired effects without subjecting the same to pressure on both sides thereof. and our invention, has for its main objects the heating of such an implement effectually by electricity, substantially as set forth in our concurrent application Serial No. 292,382, filed April 24, 1919. by providing means for the regulation of the electric current supplied to theironing head, and by the provision of. means whereby the height of the entire device may be varied to suit the convenience of the operator, all, as herein after fully set forth, and claimed specifically.

In the accompanying drawings,

Figure 1, is a central vertical sectional elevation of a puff iron embodying the es sential features of our invention;

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

Fig. 3, is a top diagrammatic view of the ironing head with the convexoconcave face or top plate removed, showing the division of the heating resistance coil into two sections, one of high resistance, and the other of low resistance.

S is a tubular standard formed with a relatively broad base S, to afford adequate support for the convex ironing head H, under stress Of'use. The base S, is formed with a recess or sleeve 3", in which is positioned a bushing b, of any suitable insulating material. Embedded in the insulating bushing b, are two metallic terminal plugs 19, p, for the reception of any metallic sockets forming part of an electric circuit.

The standard S forms a sleeve for another tubular column S, slidable telescopically therein There is a vertical slot in standard S, extending from a, to a, above and below the tightening screw G The terminal plugs p, 7), are connected electrically by copper or other suitable wire conductors to binding posts p, p, secured by suitable connection to the copper or brass tubes T, T fixed at the base of the column by the bushing s, of any suitable insulating material. Extending vertically down into the tubes T, T, from binding posts 9, p", are two copper or brass rods 7", 1, which fit frictionally into the tubes T, T.

The binding posts p", p", are connected electrically by means of the two switch arms 9, g, to any two of the three upper binding posts, u, u, u. The switch arms 5/, q, and binding posts 1)", p, u, are held in position by bushing s, of condensite, bakelite, or other heat resisting insulation.

To the three upper binding posts, a, are connected the three terminals 1*, 7", r, of the resistance coils R, R, which constitute the heating element.

These two relatively flat resistance coils. R, R, formed of suitable metallic wire, are embedded in a layer m of -mica, or other suitable refractory insulating material which is confined between the conveXo-con.- cave face-plate h, of the head H, and the clamping plate K, thereunder by means of nuts n, a, on the assembly bolts 0, e, the threaded upper ends of which latter engage with the female screw threads formed for their reception in the concave underside of the said face plate h and said bolts 0, 0, ex tending through both the clamping plate K, and the back plate h, of the head H, and being threaded not only for engagement with the aforesaid clamping nuts 11-, a, but also for engagement with the nuts n, a, which hold the back plate h, in position.

This back plate is formed with a socket sleeve M, which fits over the upper end of the standard S", said socket sleeve 72?, having an internal shoulder h which rests upon the top of the standard S". Said socket sleeve k is attached to the standard S, by means of the screw 2, which also serves to hold the bushing s, of the switch arms 9, g, in position at the top of the standard S.

Thus, by simply shifting the switch arms 9, g, the high resistance coil B (Fig. 3).

may be placed in circuit, and the low re sistance coil R, cut out of circuit; or the low resistance coil R, can be placed alone in circuit, cutting the high resistance coil, R, out of circuit; or, if desired, both coils can be placed in series in the circuit.

Thus, low, medium or high heats can be quickly and easily obtained, by simply shifting the switch arms (1, q, to electrical contact with any two of the three up er terminal posts, it. Although, in the drawing, we have placed the switch, known to the trade as a three-heat switch, at the top and inside the supporting standard S", it is understood that we could place the switch at the bottom of the column or standard, if desired, or continue the three coil terminals out through the socket sleeve 8, at the base of the iron, incorporating the three heat switch with the usual form of push socket attaching plug.

The part of the iron occupied by the low heat coil, R, will be hereinafter designated as the nose of the iron, and the part oc cupied by the high heat coil It, shall be designated as the face of the iron.

This feature oi? providing for the convenient and expeditious choice of heats is an i1 iportant feature of our invention since, through and by its use, both delicate fabrics, such as silks. chitl'ons. crapes, laces, etc, may be safely smoothed without danger of scorching, by switching on the low or medium heat; and heavi r cloths, such as ve-lvets, may be treated with the high heat.

ind another feature of import is the ease with which the height of the entire apparatus can be adjusted to suit the convenience of the operator, it being necessary only to loosen the screw G,.on the standard S, when the inner standard or sleeve S", can be lowered or raised as desired, within certain limits, of course, the screw, G, moving up or down, in the vertical slot formed in the standard S. It will be noted that the rods 1', r, slide up or down in the tubes, T, T, accordingly as the sleeve standard 9,". is raised or lowered. Thus. electrical contact is maintained at all variations of the height of the standard, without any disruption of the wiring. This construction also -Facilitates the assembling and the inspection of the devi-ne. Operators of the iron are thus enabled to work more efliciently and achieve better results when the height of the iron is adjusted to suit their physical stature.

lVhat we claim as our invention and desire to secure by Letters Patent, is

1. In a puff iron of the character designated, the combination of an electrically heated ironing head mounted upon a telescopic support, said telescopic support and means for adjusting the height thereof, fixed tubular circuit terminals within said telescopic support, and terminal rods slidable in said tubular circuit terminals and connected with the heating coil means in the ironing head, for the purpose described.

2. In a pufif iron of the character derig nated, an electrically heated ironing head formed with a plurality of heating coils oi diilerent resistances confined within said head, a telescopic support for said head, and switching means for controlling the said coils to place either one or both into or out of circuit, for the purpose described.
