Specification of Letters Patent. Patented Mar. 21, 1922.
Application filed March 24, 1919. Serial No. 384,525;
To all whom it may concern: 1.
Be it known that 1, CHARLES W. Manny,- a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Switches for Electric Flatirons, of which the fol lowing is a specification:
This invention relates to a handle for electric fiat-irons; and one of the objects of the invention consists in the'provision of a handle of the above character whereby the electric circuit through the iron is completed when the operator grasps thehandle and in which the circuit is broken when the operator loosens his or her grip on the handle, so that the possibility ,of the iron becoming over heated and starting accidental fires on not in active use is eliminated.
A rther object of the invention consists in the provision of certain means whereby the electric circuit through the iron can be established and maintained for an indefinite period of time to initially raise the temperature of the iron to the de- I sired point without the constant attendance -tive positions of'theparts comprising my invention. Fig. 3 is a transverse sectional view, on the line 33 in Fig. 2. Fig. 4: is an end View of the handle, on the line 4-4 in Fig. 2. d
Referring to the drawings, 10 represents the flat-iron and 11 a U-shaped sup ort between the upright free ends 12 an 13 of which the handle is mounted a fixed distance above the iron 10. The handle for the iron may be composed of fiber, rubber, wood or other suitable material, andis-preferably formed in halves comprising the sections 14 and 15 to reduce the cost of manufacture, since the internal recesses. for imparting the necessary clearance for metal core and the working parts, are more easily formed in the sections than would be possible in a single piece of material.
connection is formed to allow free vertical.
movement of the opposite end of the handie. The movable end of the handle is arranged so that the end of bar- 18 rides against the inner face of upright 13 of support 11, whereby a metallic connectionis efi'ected between the upright ends 1.2 and 13 of support 11 and flatiron 1-0. Upright 13 is provided in its edges with marginal recesses 21 to form shoulders 22' and 23 which'come into contact with a crossbar 2-5 and limit both the upward travel of the handle and accidental separation of the parts.
Through the movability ofone end ofthe handle the electric circuit is established or broken and as the electric circuit is normally open when the iron is out of use the electriccircuit is kept open by holding the movable end of the handle in its elevated position through the medium of a spring 30 which bears at its upper end against bar 18 and its lower end resting upon shoulders 31 formed in a fiber block 32 which is scoured to upright 13 by means of screws 33. Spring 30 surrounds a in 34 which is connected to-bar 18 and t e lower end of the pin terminates in a square enlargement 35 which forms a part of a switch by which the electric circuit through iron 10 is established or. broken. The two .sections 34 and 34: forming the pin are rigidly secured together by means of the transverse pins 34". When the operator grasps the handle the latter is depressed, thereby moving enlargement 35 between the opposing faces of blades 36 of the switch and closing the electric circuit. Blades 36 are insulated by fiber block 32 and by connecting conductor wire 38 with one of said. rivets and connecting the other rivet with iron 10 by means of the wire 38, and connecting conductor wire 39 directly with iron 10 a circuit is established through the latter. When the operator releases the handle the latter is elevated under the influence of spring and the electric circuit is broken.
To effect a positive connection between the movable end. of the handle and upright '13 of support 11, and to prevent breaking of the electric circuit when the operator lifts the iron bodily from the ironing board, I provide upright 13 of support 11 with an aperture 40 into which a spherical ball 41 is slightly projected when the ball and aperture are brought into registration. This connection is effected by housing the ball 41 in a recess L2 in the end of bar 18 and subjecting said ball to forced movement toward upright 13 through the medium of a pin 44 which is actuated by a hand actuator lever 45 when the operator grasps the handle of the iron. As the operator depresses the handle lever 45 moves on its pivot 46 into the handle at which time the forward end 47 of lever 45 moves pin 44 longitudinally, thereby forcing ball 41 outwardly and into aperture 40 in upright 13 when the two register. As long as the operator maintains a firm grasp on the handle a permanent connection between the handle and upright 13 is maintained, but as soon as the operator releases the handle spring 48 returns hand actuator lever i5-to normal and releases ball 41, the latter moving backwards away from upright 13 as the handle is elevated under the influence of spring 30. Spring 48 is-held against displacement by means of a lug 49 passing through the coil of saidspring.
With the above description in mind, it will be observed that when the operator depresses the handle to cause enlargement 35 to contact blades 36 the electric circuit is established through iron 10, and when,the operators grip is relaxed the handle is moved under the influence. of spring 30 to cause disengagement of the parts an break the circuit, thereby removing the possible dan er of overheating iron" 10 and starting acci ental fires, resulting from carelessness on the part of the operator in failing to turn off the electric current when through iron-. ing, or when called to perform some tem porary duty, as frequently "happens with electrically heated fiat-irons at present upon the market. 7
As a. convenience, and to remove the ne- .moved into the handle, cam 52 will bear upon and keep the forward end 47 of lever 45 depressed. By means of this construction the operator may depress the handle and actuate lever 45 to keep the switch closed, thereby maintaining a closed circuit while iron 10 is initially being heated.
It will be understood that the various metal parts will be insulated as in common practice in the electrical art, so as to safeguard the operator against accidental shocks.
Having thus fully described my said invention, what I desire to secure by Letters Patent, is-
1. The combination with an electrically heated flatiron, of a pair ofhandle supporting uprights secured to said iron,'a handle arranged between the free ends of the 'up rights, means pivotally connecting one end of the handle to the free end of one of said uprights, a pair of conductor wires, a circuit breaker arranged in the electric circuit, means carried by the movable end of the handle for engaging the circuit breaker with the handle depressed, means for normally holding the handle in its elevated position, and means 'preventin accidental separation of the movable end 0 the handle and the adjacent upright.
2. The combination with an electrically heated fiatiron, of a pair of handle supporting uprights secured to said iron, a handle pivotally connected at one end to the free end of one of said uprights, a lever arranged in said handle and actuated by the grip of the operator, and means actuated by said lever for connecting the movable end of the handle with the adjacent upright when the handle occupies a depressed position.
3,. The combination'with an electrically heated flatiron, of a pair of handle supporting uprights secured to said iron, a handle pivotally-connected at one end to the, free end of one of said uprights, a lever arranged in said handle and actuated by the grip of the operator, means actuated by said lever for connecting the movable end of the handle with the adjacent upright when the handle occupies adepressed osition, and means for holding the lever in its actuated position at the willof the operator. Y 1
4. The combination with an electrically heated fiatiron, of a pair of handle support ing uprights secured to said iron, an insulating handle, a metallic core extending through said insulating handle and pivotally 'engag ing the free end of one of saiduprights, a ball arranged in the movable end of the core, a pin for movin said ball towards the free end of the ad acent upright, andv a lever pivotally arranged in the handle and actuated by, the grip of the operator for mov} ing said pin and ball longitudinally.
5. The combination with an electrically heated fiatiron, of a pair of handle sup-= porting uprights secured to said iron, an
through said insulating handle and pivotrally engaging the free end of one of said uprights, a ball arranged in the movable end of the core, a pin for moving said ball towards the free end of the adjacent upright, a lever pivotally arranged in the handle and actuated by the grip of the operator for moving said pin and ball longitudinally,
and means for holding said lever in anactuated osition. I
In wltness whereof, I have hereunto set 10 my hand and sea] at Indianapolis, Indiana, this 10th day of March A. D. one thousand nine hundred and nineteen.
