Patented llIar.. 14, 1911.

To all whom if may concern:

Be it lnown that we, Ronunr Passion MooDiE and CHARLES WARREN BALL, both of the city of Ottawa, in the county of Carleton, Province of Ontario, Canada, (postoilice address is 417 Sparks street, Ottawa Ontario,) having invented certain new an useful 'Improvements in Electric Irons, do

hereby declare thatthe following is a full, clear, and exact description ofthe saine.

The invention relates to improvements in electric irons, as described in thc present specification and illustrated by the accom panying drawings, that form part of the same.-

:The invention consists essentially in 'the novel construction and arrangement of parts whereby the eiiiciency of the heating ele.'

ments is increased, and the resistance heat of the electrical-current is more directly applied to heat the iron, and whereby the iron when reversed can be used, in combination vwit-ha suitable stand, as a heater.

The objects of the invention are to provide a' combined electric sad iron and heater, economical to manufacture, and for use, efficient in operation, and one that can be readily transported from place to place..

In the drawings r-Figure 1. is a perspec tive view of the iron in reversed position used as a heater. Fig. 2. is an elevation of the iron in upright position, used as an iron. Fig. 3. is a horizontal section through. the iron showing the heating elements. Fig. 4. isa section on the line 2-2, of Fig. Fig. 5.v is a section along the line 3--3 of Fig. 3.

vLike numerals of reference indicate corre-- spending parts in each figure. V

Referring to the drawings, AA represents the body of the iron of suitable 'material and shape, B, the handle thereof, and C the stand. i

To prevent undue heating of the handle B, sance is not connected directly to the body A, of the iron, but is provided with the plate 10, which extends in the recess 1l having the lining 12, of any suitable heat insulating ma terial, said plate 10, being detained in position by the screw .13, or other suitable clamp- The body of the iron is iornied on the interior with the longitudinally extending c lindrical recesses la and l5, .opening at.

t e back, and having therein the cylindrical cores 16 and 17, of suitable insulating, heat resisting material, said cores being provided with the annular flanges 18 and 19, formed at opposite ends and adapted to support the intermediate parts of the cores out of contact with the sides of the recesses. Greater rigidity is given to thecores by means of the rods 20 and 21, extending .there-through, connected to a .rear plate 22, vof insulating material, and provided at their outer eX- trenfiities 'with the suitable binding posts 2 and 24.

The binding posts and rear plate are pro tected by the movable casing D, extending along the top and sides at the back of the iron, and resting on' the integral bottom flange, of the iron,25, and secured in position by means of the nut 26, on the screw 27 taining the conducting wires extends, said aperture beingpreferably provided with a flange 3G, formed around the exterior there,l of, about which is Wound the spiral spring' 81, extending up said cord and affording protect-ion to same; the end 32, of the spiral spring being preferably brought down and clamped beneath the nut 26.

The electrical connections are eiectcd in the usual way, the electrical wires 33 and 34; being wound ou the cores, the current passing, first through the wire on one core, back through the rod of said, core, through the rod of the opposite` core and back through the resistance wire on the said opposite4 core. A

The cylindrical recess Sain the body oli the iron is provided' for the purpose of conveniently heating a curling tongs or ,thel like, and is adapted to holden-ine. I

From the fore oing it will be readily seen that, the heat o' the resistance Wire is di# rectly communicated :to the ,body of" the iron itself, .and that, While none ot' the heat. produced can escape, the recesses being, well toward theicenter of the iron, a very small amountot heat radiation-Will occur.4

The rods 20 and 21, besides givin additional support to the cores 16 and 1 simliy the construction by enabling' the bind mg posts 23' and be formed on'the extremities thereof.

, As changes may be made in the foregoing construction, und lnnny apparently widely di'tlerent elnbodnnents of our invention may be resorted to, Without deymrting troni the spirit or scope thereo'l, itis intended that 5 all matter contained in this slrieeilieution n nd drawings, shall he i-nterl'netml as illustrative, und not in nv limiting,l sense. lt also to be understood that the. language ot the :reconn ntnying chiiins is intended to cover .Such ,generic :1nd specific tentrnee of the inventirni :is might be4 smid to he inel :ded thereby.

Vv'hnt we cln'irn for our 4invelition istil. An electric iron hun/ing,` cylindrical recesses therein, hollow cores insulating materiel j'orlned with flanges at each end, ndnpted to lit in sind recesses, heating-conductors wound on said cores between said flanges ont of Contact With und in close,

proximity to said iron, said heating-condnetors being insulated from said iron by smid end-flanges, rods extending through snid hollow cores, binding posts toi-ined on seid rods, uV rearplate of insulating mate rial. eonnecting, the cores with said redrplate, a easing member inclosing the rear plate, it bottoni flange 'formed integral with the body of the iron adapted to Support said easing member.

2. An electric iron having cylindrical recesees therein, hollow cores of insulating mat'erlul, forn'ied wi th supportin eollurs at; en eh end, returning` wires throng] said cores,

l t henting-eomluctore Wound on said eores hetactthroughout their entire, length with said iron by means oft' said snjjaporting eollnrs, binding posts formed on sztid ret-urning wires, a. rear-plate of insulating ninterinl connecting the Coree 'with said rearplate, a. Casin member inclosing therein?- plate, means tor Supporting same from the body oitl the iron whereby the connections P:nre not affected by the heat of the elements.

3. An electric iron having Cylindrical holes therein, hollon7 cores of insulating 1n :L- terizil formed 'with end Supporting collars, adapted to tit in smid holes` heating-eonduc tors arranged on Suid cores between said eol lars, so that said conductors lie throughout their entire length in close proximity to the surrournlingmetal, whereby the heat energy generated is directly transmitted to said surrounding;y metal.
