'Application filed August '1, 1908.

Be it known that i, ALFRED O. W rrrrrvronn, a'citizen oi the United States, residingI at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Electric Smoothing-irons, oi which the following is a spec-iiication.

My invention relates toim rovements in and ias for one of its objects, the provision of a device of this character in which the heat will be radiated direct throughout the entire body of the iron' without loss, which will operate with a minimum current consumption and which will be practical and eiiicient in all respects.

may be secured to the Abody of the iron by Another object is to provide suitable protection for the leading-in wires as well as a rest to su port the iron when not in use.

A furt er object is to provide supporting cores for the heating or resistance units which will permit oi the ready insertion and removal of' such units, and also to mount the units in such manner that they will radiate their' heat outwardly into the surrounding iron body.

With the foregoing and other objects in the invention consists essentially of an iron body and a cover thereto mounting a handle, and. heating units mounted inthe body of the iron so as to radiate their heat outwardly into the surrounding material of the iron.

The invention also resides incertain other novel features of construction, combination and arrangement of vparts substantially as disclosed herein and as illustrated in the accomp anying` drawings, in'which:

Figure 1 is a side elevation of my improved l smoothing or sad iron with part ofthe iron shown in section to illustrate .the mounting ofthe heating units. Fig. 2, is a plan view of the Asame showing in dotted lines, the ar- Fig. 3, is an l end view oi the iron to illustrate the leadingin connections. l

The body 1,o`f the iron is of conventional. shape and may be made in any desired size. Within the body are formed a number of seats or recesses 2, which preferably taper downwardly andto close said seats or recesses, a cover plate 3, is provided which Specification. of Letters Patent.

screws or suitable iastenings 4. This cover is preferably made in two parts, lower iireprooi heat-insulating part and an upper sheet metal part, and this sheet metal part is extended straight rearwardly to iorm a base 5, on which the terminal posts 6, are mounted, thence directed angularly upward to iorm a guard 7 for the terminals. A pair or' side wings S, are struck Idownwardly and rearwardly from the base eXtension which serve as a rest for the iron when not in use. A somewhat U-shaped member. provided with upstanding arms 9, is. iastened upon the cover, and' to said arms is secured a handle 10. A

The heating units consist oi' a' series of coils of suitable resistance wire 11,which is Vwound upon the spools or cores 12 these cores being made of porcelain, clay, or other suitable insulating material. These cores are tapering in forms so asto iit within the the body oi the iron and are formed with the external spiral grooveways 13, to receive the turns of resistance wire and to keep the convolutions separate from eachother. rIhe cores also have an upwardly converging opening 14,- therea heavy 5 through to render them as light as possible and so as to allow for a certain amountvof expansion.v A lining 15, of asbestos or other ireproof insulating material is placed' in eac of the recesses or seats in the iron body so as to prevent the coils from short-circuiting against the walls of the recess.

In use, the .terminals are connected with a suitable source of electrical. supply, preterably by means of an extension cord and and the leading-in wires rent to the heating coils. The coils may be Plea 16, conduct the curl connected together in series or in any other way. As the coils become heated, the cores expand, bringing the coils in more intimate contact with the theheat isv radiated directly outward into theA medium. The heat thus 'spreads radially outward into the surrounding medium so that the iron is heated 'uniformly and all the heat energy is utilized.v When not in actualv use,.the iron would be tilted back uponthe supporting wings, which serve in the nature of a stand and also serve in combination with the upstanding guard, to guard and protectl the terminals.
