ELECTRIC IRON.

To all whom it concern:

Be it known that I, ALBERT VVIoKs, a

subject of the King of Great Britain, re

siding-at Guelph, in the co'unty of \Vellington and Province of Ontario, Canada, have invented certain new anduseful Improvements in Electric Irons; and I do declare the following to be a full, clean and exact description of the invention, such as will whereby the upper 'portion of the body of the iron will be prevented from becoming- I heated.

Another object is to; provide. a simple,

- strong and durable iron of this character,

. is a side view. of an electric 1ron constructpended claim.

the parts of which may be easily manufactured and assembled; A further object is to provide an improved construction and arrangement of heating element by means of which the electricity. is applied to the lower part-of the iron for heatingthe same.

With these and other objects-in view, the invention consists of certain nove features of construction, combination and arrangement of parts as be more fully described and particularly pointed. out in" the ap- In the accompanying drawings: Figure 1 ed in accordance with the invention; Fig. '2

of the electric heating element; Fig. 6 is a detail view of the electric heating element" removed fi-om the iron. Fig. 7 isla vertical cross section on the line 77 of Fig.1.

Referring more particularly to the draw-- ing, 1 denotes the body or base portion of the iron which may be of any suitable shape and has formed therein a recess or. cavity 2 corresponding to the shape of the base 1.' In the toe portionof the base is formed an 'ofl'fset or shoulder 3 having a threaded v Specification of Letters Patent.

' socket the purpose of which Will be hereinafter described. In the rear or heel end of the base is formed a centrally disposed lug 4 which is also provided with a threaded socket. Arranged in the recess 2 of the base 1 is a solid iron core or heat retaining 6o element 5, said core having a shape corresponding to the shape of the recess 2 and is provided on its toe end with an overhanging apertured lug 6 which is adapted to engage and rest on the shoulder 3 in the base of the iron, and with said apertufed lug and threaded socket is engaged'a-fastening screw I 7 by means'of which the forward end of the core is secured in the base. In the rear or 7 heel end of the core is also formed a passage through which is inserted a fastening screw 8, said screw being engaged with the threaded socket formed in the lug 4 at the heel end of the iron thus securing this end of the core in place. In the center of the core 5 is formed; an upwardly projecting. boss 9 havingformed therein a threaded socket 10.

Arranged on the-base 1 and over-the core 5 is a hollow removable top or upper section 11, the upper side and front portion of which is rounded or curved as shown. In the frontend and. in the opposite sides near the rear end of-the base 1 are formed notches 1 with which are engaged lugs 11 formed on the upper section whereby the' latter is centered and held against lateral movement. In the curved or rounded upper portion of the top or upper section is formed a series of vertically disposed passages 'or slots .12 and a central longitudinallydisposed .slot

13. The slots 12 are provided to form venti-" lating openings through which they heat of the iron is permitted to eseape,thereby keep ing the upper portion of the iron cool. vThe slot 13 is, provided to receive a tongue or rib 14 formed on the lower side of the ban le' attaching shank 15 which curves upwar y from the upper portion ofthe iron as shown. In the upper end of the shank 15 isscrewed 101 a bolt 16 on which is arranged a handle 17 formed of wood or other suitable material, said, handle being'secured in place by a nut 18 arm. on the oute'r end-of the bolt. .as shown. the rear end of the lower'portion. 10. of the shank .15' is formed a screw hole which alines with the-threaded socket 10 in theboss 9 and through said holein the tongue-is inserted a handle and top fastening screw 19 which is screwed into engagement with the threaded socket in theboss 9 thereby securely fastening the handle and upper section of the body of the'iron in place. 3

In the rear or heel end of the core 5 is formed a recess 20 in the upper wall of which is secured the lower ends of combined binding posts and connecting plugs 21-which are suitablyv insulated from and secured to the core 5 by clamping nuts 22 and insulated washers 23. To the lower-ends of the posts 21 are connected one end of electric conducting strips or wires 24 by means of which the posts are electrically connected to the electric heating element arranged in the base of the iron. as hereinafter described. The upper ends of the binding posts 2L project through an opening 25 formed in the rear end of the top section 11 of the iron and are adapted to receive the socket of a flexibleconducting element (not shown) but by means of which electricity is supplied to the heating element of the iron. Above the core 5 and between the same and the top of the iron is arranged a filling or layer of asbestos or other non-heat conducting material.

My improved electric heating element comprise's'two bars or'plates formed of mica or similar non-conducting material 26. The

two plates or bars 26 are arranged side by side in parallel relationbeneath the core 5 and between the same and the bottom of the base 1 and said bars or plates 26 are wrapped continuously by metal strips or wires 27, said wrappings forming resistance coils whereby the ,current of electricity passing through the same is caused to produce an intense heat. The forward ends of the strips 27 are connected together by a suitable clip 28 or said strips may be formed in onecon'tinuous piece. The. opposite endsof the strips 27 are passed through apertures formed in the rear end of the plates 26 and are suitably fastened to the latter. With said rear ends of the strips 27 are connected the inner ends of the conducting strips 'or wires 24 the upper ends "of which are secured to the binding posts 21 asshown. I

Between the upper side of the wrapped bars, forming theheating element," and the core 5 is arranged a protecting plate 29, and below the heating element and between the same and the bottom of the base v1 is arranged a protecting plate 30. The protecting plates 29 and 30 referred to may be formed of any suitable material but mica is preferably employed. The opposite edgesof the core- :5,. are insulated from the sides of the base of the iron by strips 31 of mica or similar non-conducting material, while a similar strip of mica is arranged between the rear of the core and the adjacent rear end of the base. i

From the foregoing description taken in connection with the accompanying drawings; the construction and operation of the invention will be readily understood without requiring a more'extended explanation.

' Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advan-. tages of the invention as defined in the appended claim. Having thus described my invention, what I claim is:

An electrlc 11'01'1 comprlslng a base having a cavity formed therein, a heat retaining core arranged in the latter, said core having a toe and heel lug each of which is adapted to engage with shoulders forming the end walls of the cavity in the base, fastening de-. vices passing through said lugs and into the shoulders for detachably securing the core to the base, binding posts secure to the core and projecting upwardly therefrom, an electric heatingelement arranged between the base and the core, saidelement comprising parallel arranged bars of non-conducting material, metal strips on said bars to form two resistance coils in series, electric conducting metallic strips to connect each end of said heating element with one of said binding posts, means for insulating the heating element from the remaining parts of the iron, a cover sectiondetachabl secured to the base into which the core pro ects, the latter having an upwardly project-ing boss, and, a handle secured to said. cover and boss, whereby the core is secured to the cover within the longitudinal passage formed therein. i

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALBERT WICKS.
