ELECTRIC FLAT-IRON.

To all whom it may concern:

Be it known that I WILLIAM MORGAN, a citizen of the United states, residing at Los in the county of Los Angeles and State of California, have invented new and useful Improvements in Electric Flat-Irons, of which the following is a specification.

My object is to make an electric flat iron having an automatic circuit breaker so as to insure that the iron will not be heated when not in use and so that the circuit may be broken at any time during the operation.

Figure 1 1s a perspective of an electr c flat iron provided with an automatic circuit breaker in accordance with the principles of 'electric heatin element of any desired construction. A p ug socket 2 extends upwardly from the top of the rear end of the flat iron 1 and the terminals 3 and 4 of the heating element lead to the spring seats 5 and 6.

The socket 2 has a lining 7 of insulation and the terminals 3 and 4 lead through the lining fee to the spring seats 5 and 6 resting upon the insulation 7 Spring casings 8 and 9 extend upwardly from the spring seats 5 and 6 and expansive coil springs 10 and 11 are mounted in the spring casings in electrical contact with the seats 5 and 6, said springs normally extending above the casin 8 and 9.

The insulating plug 12 is mounted to slide up and down in the socket'2 and the terminals 13 and 14 of the electric supply line are fixed in the upper end of the plug and con nect electrically with the screws 15 and 16 inserted upwardly from the bottom of the plug, the heads 17 and 18 of the screws'beinzin position to contact with the springs 10 Specification 01' Letters Patentthe post between the ears. An arm 25 extends from the supplemental handle 21 through the opening in the post between the ears and is mounted upon a pivot 26 inserted through the ears and through the arm, and the extreme rear end of the arm 25 is mounted in the bearing 19 upon the pivot 27. An expansive coil spring 28 is mounted in a bore 29 formed upwardly in the main handle 22 Patented Jan. 7, 1919.

and enga es the supplemental handle 21, the

tension 0 the spring being exerted to push the supplemental handle 21 downwardly and raise the plug 12 and break the circuit.

When it is desired to use the flat iron the operator grasps the supplementalhandle 21 together with the main handle 22, forcing the supplemental handle 21 upwardly against the main handle 22 and forcing the plug 12 downwardly to press the heads 17 and 18 against the springs 10 and 11 and 7 close the circuit and heat the iron. In the. course of the operation when the iron becomes sufliciently heated the operator may release the supplemental handle 21 and con tinue to grasp the main handle 22 for ma; nipulating the iron and when the work is done the operator'may go away and leave the iron and the circuit will be automatically broken by the supplemental handle 21 swinging downwardly under its own weight and the tension of the spring 28.

Various changes may be made in the details of construction without departing from the spirit of my invention as claimed.

I claim:

1. The combination with an electric flat iron having a plug socket extending upwardly from the top of its rear end and the terminals of its heating element leading into the socket, of spring seats in the bottom of the socket and connected to the terminals of the heating element, a lining of insulation for the socket, spring casings extending upwardly from the spring seats, expansive coil springs in the spring casings against the spring seats; said springs normally extend-' ing above the casings; an insulating plug mounted to slide up and down in the socket and adapted to connect to the terminals of a supgly line, screws inserted upwardly from the ottom of the lug in electric connection with the terminals; the heads of the screws being in position to contact with the springs when the plug is pushed downwardly and so that when the plu is raised sufficiently the circuit is broken tween the heads of the screws and springs; and means for operating erator upon the hand-hold of the iron.

2. The combination with an electric flat iron having a socket extending upwardly from the top of its rear end and a plug slidingly mounted in the socket, of a supplemental handlepivotally mounted below the I 10 main handle and extending through one 'of the post's supporting the main handle and' connected to the plug, and a spring embedded in the main handle and engaging the supplemental handle to throw the supplemental handle downwardly and raise the 15 plug.

In testimony whereof I have signed my name to this specification.

WILLIAM MORGAN.
