ELECTRIC RON.

Specification of Letters latent.

Patented Sept. 3, H8.

Application filed August 30, 153i?. Serial No. 188,979.

To all tui/wm t may' concern.

Be itlrnown that l, CHRISTIAN MARTIN- snN, a citizen. of Norway, residing at Seattle; in the county of King and State of W ash ington, have invented certain new and usefnl Improvements in Electric irons, of

which the following is a specilication.'

lhis'invention relates to flat irons, and more particularly to a flat ironlieated by electricity.

@ne of the mein objects of the invention is to provide an yelectric liet iron having f means which may be easily operated by the user for controlling' the circuit of the heating element or resistance. A further object is to provide simple and eflicient meansl :tor

closing or openingthe circuit of the heating element. Another object 1s to provide a tiet iron the handle of 'which is mounted for rotary movement in either direction having means connected to the handle for closing the circuit of the heating element when the handle is turned in. one direction and for opening thisv circuit when 'the handle is turned inthe other direction. Further objects Will appear in the detailed description.

ln the drawings:

Figure 1 is a vertical horizontal sectional View taken through a flat iron. constructed 'in accordance with my invention.

Fig. 2 is a front view olf the handle and the members associated therewith for opening and closing the circuit of the hea-ting member with the circuit ot' this men'iber open,

li'lig. 53 is a similarview with the 'circuit of the heating;u member closed. y

Fig. 4l is a fragmentary top plan view of the iron with the cover rcn'loved.

llip: 5 is a' detail sectional view ol: the connections between the n'iovable contact member and the means lor operating the saine.

rihe 'tlat iron is of standard *construction having the base l, Weight or body portion and cover Il mounted thereon, the base being provided with a ridge or bead 5 for main taining the cover 'in proper position. The body is secured to base l by a screw 6 pass ing through the same and threaded into a boss 7 integral with the base. The head 8 of screw 6 is extended and is provided with a boreI into which is threaded e securing screw 9. This screw is inserted through the horizontnl bar l0 of a U frame 11 mounted above the cover 3 and maintained in spaced relation thereto by the centrally flanged stud pins 12 inserted through alined openings in the cover and bar 10. By this means, the base, body, cover-,end handle bracket are all secured together to form a unitary structure.

The body 2 is provided, adj acentits broad or base portion with a central recess 13. Two .spaced contact members or plates 14 and l5 are secured to the body in spaced relation and are electrically insulated there from. These contact members are provided With posts 1G and l?, respectively, which are adapted to fit into a socket member 18 having` the usual spring clips or jaws for receiving these members which are connected to the Wires of a cable or cord i9. rllhe contact plate 14 is provided with an integral eer 20 which is electrically connected by a lead 2l to one end of the resistance strip or ribbon 22 which extends the full distance around the inside of base land is electrically insulated therefrom in the usual manner. r i e lhe construction so lar described 1s standard anddoes not form any part of my in- 'sumiorting plate 221. This plate provided with an upwardly directed arm provided at its upper end with laterally extending; trunnions which .tit into spaced sleeves 23 Jformed at the inner end of a movable contact plate 24. An oi'iiset linger 25 is secured to plate 2l adjacent the forward end thereof. This linger is connected by' a lead 26 having; a flexible joint :27' to the other end olI resistance strip Q2. Flate 2% is movable toward and away from the inner upwardly directed contact point formed integrally with contact plate l5. lllhen plate 2l is depressed it will be brought into tight frictional engafement with member 28 so as to electrically connect con-tact member l5 to the other end ofresistance strip 22. For this purpose, supportingl plate 221 is electrically insulated from body 2, as shown in Fig. l of the drawings. It will be evident that, by raising- 'plate 24 out of engagement with member :28, the circuit of 'the resistron to cool; or, by bringing plate 24 intoI contact With1-1nember28 the circuit of the@ resistance will be closed so as to heat the@ iron. The movable plate 24 thus provides simple and eiicient means for controlling the circuit of the resistance strip.

A rod 29 is rotatably mounted in the upper ends of the arms of U-framell. This rodis turned over at a right anle at one end to provide a radially dispose arm 30. The outer end of this arm is bifurcated to receive the reduced upper end of a link 31 which is pivotally secured, as at 32, to the forward end of a lever 33 which is rockably mounted intermediate its ends on va finger 34 extending upwardly from cover 3. The rearward end of lever 33 is pivotally secured, by screw and nut means, as at 35, tothe upper end of a standard 36 which is operable through an opening 37 in cover 3. Standard 36 is provided, at its lower end, with a disk-like base 38 which is secured to, but electrically insulated from, the contact plate 24. A handle 39 is secured on shaftv 29.' This handle is provided, at each end, with the usual shoulder or fiange 40 the lower portion of which is cutaway to permit 'limited rotary movement or turning of the handle in either direction. When the handle is turned' in a clock-wise direction, the outer end of lever 33 will be depressed thus raising the plate 24 and breaking the circuit of resistance member22. B turning the handle in the opposite direction, the circuit of,the resistance will be closed so as to heat the iron. By this means, I provide very simple and eflicient means where- `by the user has direct control over the heating means, this circuit controlling means being so constructed and mounted as to permit the circuit for the heating element to be open or closed when the iron is in use with-l out in any way interfering with the ironing operation. This gives the user direct control over the iron so that the extent to which the same is heated may be quickly and easily regulated thus eectually eliminating all danger of the articles being ironed being burnt or scorched while insuring that the iron will beheated, at all times, to such a decree as to insure proper ironing of theA articles being operated upon.

There may be slight changes madein the construction'and arrangement of the various parts of my invention without departing from the field and scope of the same, and I intend to include all such variationc as fall within the scope of the appended claim, in this a plication in which a preferred form on y of my invention is disclosed. I

What I claim is:

The combination with an electric iron having a base, a body portion, and a cover; of a'resistance mounted in said base, fixed contact members carried by said body and adapted to be connected to the opposite sides of an electric circuit, one of said membersbeing connected to one end of said resistance,a contact plate movable into and out of contact withqthe other fixed member andconnected to the other end of the resistance, a handle mounted on said cover for rotary movement, -an arm secured to said handle and projecting radially of the same, a lever pivotally mounted intermediate its ends on said cover and conected at one end to the` said movable contact plate so as to move the same toward or away from said fixed contact member when the lever is rocked, and a link pivotally connecting the outer end of said arm and the other end of the lever.

` In testimony whereof I affix my signature in presence of two witnesses.
