UNITEE PATENT SWITCH.

Application filedSeptembcr 17, 1923.. Serial No. 683,227.

To all whom it may concern:

Be it known that I, MICHAEL hTORRISSEY,

a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Switches, of which the following is a specification.

This invention relates to an iron, the general object of the invention being to provide means whereby the iron can be heated to different degrees, thus reducing the consumption of current by only heating the iron to its fullest extent when necessary. Another object of the invention is to r provide means whereby the low heating means are rendered active when the iron is placed in a vertical position upon its support with means for automatically turning on full current when the iron is placed in horizontal position.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying draw- 30 ings wherein like characters denote like or corresponding parts throughout the several views, and in which: m

Figure 1 is an elevation of an iron con structed in accordance with this invention.

Figure 2 is a plan view.

Figure 3 is a section on line 33 of Figure 1.

Figure 4 is a diagrammatic view of the iron in upright position.

Figure 5 is a diagrammatic view of the iron in horizontal position.

F igur-es 6 and 7 are detail views.

In these views 1 indicates the body of the iron, 2 indicates the handle thereof and 3 and 4 indicate the terminals for receiving the plug which is electrically connected with a source of supply. The heating element 5 is provided with a pair of coils 6 and 7, r one end of the coil 7 being connected with the terminal 3 while the other end of the coil 7 is connected with the coil 6 by the extension 8. The coil 6 is connected with a stationary contact block 9 while the extension 8 is connected by the conductor 10 with a stationary contact block 11, these contact blocks being placed in a chamber 12 formed at the rear end of the iron. A movable contact block 13 is arranged between the blocks 9 and 11 and a stationary contact 1 1 engages the block 13 and is electrically connected by the conductor 15 with the terminal i. A rod 16 passes through the rear end of the chamber and through the block 11, from which it is insulated, and is connected with the block 13, being insulated from said block. This rod has its outer end connected with a cap 17 which is slidably mounted on the chamber and which is normally held in its outward position by means of the springs 18. A set screw 19 is carried by one wall of the chamber and engages a slot 20 in the cap so that the cap can be held in its inward position against the action of the springs 18 by tightening said screw.

As will be seen when the block 13 is in engagement with the block 11 the current will pass from the terminal 3 through the coil 7, conductor 10, block 11, block 13, contact 14 and conductor 15 to the terminal 4. Thus the iron will be heated to its fullest extent. When it is desired to heat the iron to a lesser degree, say when it is not being used or when it is used toiron smaller articles, the cap is pushed inwardly either by hand or by setting the iron on end and then the current will pass from the terminal 3 through both the coils to block 9, block 13, contact let, conductor 15, to terminal 4. Thus the iron will be heated to a less extent and less current will be used. If the iron is set on end, the current will be automatically caused topass through both coils and when the iron is placed in horizontal position again the springs will force out the cap so that the switch will be automatically operated to cause the current to heat the iron to its fullest extent. When the iron is to be used at low heat the cap can be pushed in and held in this position by tightening theset screw 19. The switch parts are placed upon an insulated base 21 which is arranged in the chamber 12.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A switch for use upon electric irons comprising a substantially i rectangular chamber adapted to be positioned upon the rear end of the iron, a substantially U-shaped cap receiving the side walls of: the chamber therein and adapted for sliding movement thereon, sp ing tensioned means included between the chamber and U-shaped cap for normally holding the cap outwardly, means included on the cap and chamber whereby the cap may be held in adjusted positions thereon, a pair of switch cont-act members arranged within the chamber, a contact positioned within the chamber and connected in circuit with the iron, and an auxiliary slidable contact member arranged between the contact members and engaged by the contact and adapted for simultaneous sliding; movement with the substantially U-shaped cap.

2. Aswitch for use upon electric irons comprising a substantially rectangular casing adapted to be arranged upon the rear end of the iron, a substantially U-shaped cap receiving the side walls of the chamber therein and adapted for slidable movement thereon, spring tensioned means included between the chamber and cap for forcing the cap outwardly, a set screw associated with the chamber and cap whereby the same may be held in adjusted position thereon, a pair of stationary contact members arranged within the chamber, a contact positioned within the chamber and having communication "ith the iron, an auxiliary movable contact member arranged between the stationcontact members and engaged by the contact, and a shaft member extending transyersely through one of the stationary contact members and having its opposite end portions connected to the cap and movable contact member whereby the same may simultaneously open and close the switches within the chamber.

In testimony whereof I afliX my signature.

MICHAEL MORRISSEY.
