ALBERT H. SMITH, F NEW YORK, N. Y., ASSIGNOB TO FRANCES BOCKEFELLEB KING, 0F NEW YORK, N. Y.

ELECTRIC FLATIRON.

To all wlwm it may concem:

Be it known that I, ALBERT H. SMrTH, a citizen of the United States of America, and a resident of New York, county of Queens, and State of New York, have. in-

vented certain new and useful Improve` ments in Electric Flatirons, of which the following is a specification, reference being p had to the accompanying drawings, formin a part thereof.

y invention relates to electrically heated sad irons for laundry and domestic use, and particularly to those of the general character shown and described in Patent No. 1,249,638.v granted December 11, 1917, to

Adele Rockefeller King.

One object of m invention is to provide a device of t e aforesaid character that shall be particularly serviceable and durable in construction and adapted to avoid the vibration and arcing of the contacts of the circuit interrupter, with which the iron. is equipped.

Another object of my invention is to pro- 26 vide a stand'or rest adapted to receive the iron when not in use and to hold the circuit interrupter in either a closed or an open position as desired, without necessitating the downward pressure of the hand of 80 the operator on the handle which is essential for maintaining the circuit when the iron is in use.

In order that my invention may be thoroughly understood, I will now proceed to describe the same in the following specification, and will then point out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a side elevation of an elec-` trically heated iron arranged and constructed in accordance with my invention and constituting one embodiment thereof, the shell of the iron being broken away and shown in cross section to disclose the interior mechanism.

Figurev 2 is a sectional plan view taken on the line 2-'2 of Figure 1.

Figure 3 isan enlarged view of the body of the iron with the shell broken away and the circuit interrupter shown in open circuit position.

Figure 4 is a View corresponding to Figure 3. with the interrupter shown in a closed circuit position.

Figure 5 is a sectional detail of the interrupter contacts taken on the line 5 5 of Fi ure 3.

igures 6 and 7 are sectional details taken respectively on the line 6-6 and 7-7 of Fi re 4.

ike parts are desi nated by the saine reference characters in sill the fi ures.

The sad iron illustrate comprises a smoothing iron base 10, a protected electric heating element 11, a spacing plate 12 of insulating material, electrical terminals 13, and electric circuit interrupter 14, a shell 15, a handle 16, and a terminal plug 17.

The iron when not in use is adapted to rest on a stand 18 provided with anoverhanging member preferably in the form of a semi-circular band 20, which is arranged to cooperate with a projection 21 of the handle 16 in such manner as to hold the cir cuit interrupter 14 in a closed circuit posi- 76 tion when the iron is set on the stand.

The handle comprises a frame 22 Which is pivotally connected to the shell of the iron at 23 and is provided with a projection 21 for the purpose above specified. It also has an angular projection 24 which extends through a suitable slot 25 in the shell of the iron and serves to limit the outward movement of the handle of the iron as shown in Figure 3 and to actuate the circuit interrupter as shown in Figure 4, dependent upon the position'of the handle.

The terminals 13 cooperate with the contacts of the plug 17 which is attached to the usual flexible cord conductor 26 and may be detached from the iron at will.

The circuit interrupter which is one of the vspecial features of my invention, comprises a main contact arm 27 which is pivoted at 28 on a bracket or support 29, at- 95 tached to the base of the iron by screws 30, an actuating lever 31 pivoted on the same bracket at 32 and yieldingly connected to the contact lever 27 by a spring 33 which tends to hold the actuating arm 31 against 100 the shell and to throw the contact lever 27 into its open circuit position. Mounted on the same pivot 32 is a latch 34 which is in the forni of a bell crank lever and has a latch arm 35 which is adapted to extend 105 through a slot or opening 36 in the lever 27 and to latch the lever 27 in a closed circuit position as shown in Figure 4, after it has been forced into this-position by the downward movement of the actuating lever 110 handle pivotally attached to the body, of a circuit interrupter Within the shell comprisinga switch arm or contact lever, yielding means tending to.open the interrupter, a latch fastening the interrupter in closed position, and actuating means including a projection from the handle on the outside of the shell and a cooperating actuating arm inside the shell for forcing the contact arm into closed position.

6. In an electric iron, the combination with a body having a base and a shell` a handle pivotally attached to the body, of a circuit intcrrupter Within the shell comprisinzgr a switch arm r Contact lever.y

yielding means tending to open the interrupter, a latch fastening the interrupter in closed position, and actuating mea'ns including a projection from the handle on downward pressure is exerted on the handle l or when the iron is placed on the stand With the holding projection in engagement with the orerhanging member of the stand.

In witness whereof I have hereunto set my hand this 8th day of April7 1921.
