No.=887,871. Specification of To all'wko'm it may concern: i

Be it known that I, CLARErron-"L. TAYLOR si -resident (if Alliance,- in .thecounty of Stark and State of Ohio, haveinvented oertainnew and useful Improvements in Electric. Heat ers; andl do hereby declare the following to be a fullyclear, and exactidesoriptionof the invention, such as will-enable others skilled" in theart 0 which it appertains to make/ and; use'the same. v

My invention relates-to'irn rovenientsin electrieheaters, wherein an e ectrical resistance conductor is, employed. as. an element to. supplyheat. to the surface. of the derice. whichssu'chelementis employed The object of rnyzpresent:inventionzis toso. construct and arrange the heating element as to-insure such adistribution and circulation of heat that the latter will be directed to or.

I

A further object is to construct an electrically-heated sad iron wherein the results above enumerated will be attained without sacrificing the conventional shape of the iron.

A further object is to so construct an electricall -heated sad iron that the parts thereof shal be distributed in suchmanner as to cause the heat to flow down to the thin edges of the polishing face of the iron and allow onlya minimum amount to be lost by esca e throng the frame and radiation into the air.

A further :object is to construct an-electric-' ally-heated iron in such manner that the parts can be readily'and .uickly assembled,- er itted'to circulate ementand the lower,

and so that air' will be between theheating e portion of the frame and thusassist to prevent undue heating'of the handle.

' With these objects in view, the invention consists in certainnovel features of construction and combinations" and arrangements of parts'as hereinafter set forth and pointed out 1n theclaims.

For the purpose of securing t e severa plates 1, 2 and 5 together with the resistance element in place between the plates 1 'and 2 and in comparatively close proximit to the working 'face of the former,-'a b t 12 is employed. This bolt passes through openings in the plates Zand (from which it is insulated by means of asleeve 13) and enters a threaded socket in the plate 1-,-a nut 14 located on said bolt, being screwed down against the top of. plate 5.

The bolt 12 extends some distance above the nut'ld and passes through a cross bar 15 located centrally between the ends of a hollow frame or shell 16, and over said cross bar,

a nut 17 is screwed on the bolt. The depending crimeter of the shell 16 terminates a short (istance' above the erimeter of the late 1 and'is properly hel in this position by lmeans of posts 18 projecting upwardly from the up er plate 5 and engaging the top wall of the s en.

upper ends of the arms 19 are secured in the countersunk ends of a handle 21 (preferably of wood), by means of screws 22 or other Between the arms 19 and the ends of the handle, the ends of a, guard or shield 23 are secured, said guard,

of the shell 16. It will be 0 served however, that considerable space is left .over the heat- .ing eleme'ntlwithin-the shell and that a free ingress of air into this space will be ermitted between the lower edge of the shel and the plate 1. This circulation of air will tend to prevent any appreciable amount of heat In order'to avoid inductive eiiect in the heating coils, each ofvsaid coils may be wound with a portion of its convolutions running in one direction and the remannng portlons of its convolutions running in the reverse dime tion.

By means of the construction and arrangement of parts above described, the heatlngelement-is rendered very compact; is located a considerable distance from the handle, and is inclose proximity to the working face of the device, and the metal is so disposed with relation to theheating coil and the worki face of the device, as to insure the thoroug and effective heating ofthelatter.

Variou s ht changes mi htbe made in the detail'so construction 0 t ny-"invention, and the form of the parts may be. altered to adapt the heater to devices other than sad ironp, without departing from theispirit of my'm'vention or'hmiting its scope, hence I do'not wish to limit myself to .the precise details herein setforth.
