ELECTROMAGNET.
Application filed September This invention relates to electromagnets especially designed for the operation of locks, the invention being useful for the operation of door locks and in various other capacities.
An object of the invention is the provision of a magnet which is eflicient in use, practically instantaneous in its operation and will exert a relatively great amount of pulling power for its size and construction.
lVith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.
In the drawings Figure 1 is an elevation partly broken away showing a fragmentary portion of a door with the improved magnet arranged for operation of the door lock.
Figure 2 is an enlarged elevation of the magnet with the cover removed.
Referring to the drawings in detail wherein like characters of reference denote corrcsponding parts, the reference character 10 indicates the housing or casing of the magnetwhich is provided with suitable attaching flanges 11 and with a removable cover 12 by means of which access may be had to the interior of the casing.
Mounted within the casing is a pair of normally spaced electromagnets 13 and 14. These magnets are of like construction and each includes a substantially E-shaped core 15. A spool 17 is mounted in middle 16 of the core and is provided with a suitable inductance winding 18.
The magnet 13 is stationary within the casing 10 and is spaced from the casing by an insulating lining 20. Extending across the casing and through the bars of the magnets are spaced parallel rods 21. upon which the magnet 14 is slidable. The bar of the magnet 14 has extending therefrom an arm 19 for connection with. the mechanism the magnet is designed to operate.
In F lgure 1 of the drawings the magnet is shown connected with a lock 22 of a door 23 and for this purpose, the arm 19 is connected by means of a rod or cable 24 with one end of a coiled spring 25. The opposite end of this spring is connected to an arm 26 which extends from the latch or bolt of the lock 22. The terminals or binding posts of 23, 1925. Serial No. 58,146.
the magnet have connected thereto suitable electric conductors 27 which are designed to be connected to a suitable source of current, while a switch 28 connected with one of the conductors 27 will control the flow of current through the magnets.
The door 23 may be provided with a spring 29 which exerts a tendency to hold the door in open position.
WVhen the switch 28 is operated to close a circuit through the magnets 13 and 14, these magnets will be energized, the magnet 13 attracting the magnet 14 and vice versa, so that a double attraction is set up and a relatively powerful pull exerted upon the arm 19. This will expand the spring and when the latter has become sufliciently tensioned, the latch or bolt-of the lock 22 will be retracted and the door opened under the tension of the spring 29.
While the magnet is shown and described in connection with a door lock it is apparent that the said magnet is useful for vari ous other purposes and it is not the purpose of the application to limit its use in this respect.
The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.
Having described the invention what is claimed is 1. In an electromagnet, support, a magnet fixed to the support, a relatively movable magnet carried by the support and spaced parallel slide rods carried by the sup port to slidingly mount the movable magnet upon the support.
2. In an electromagnet, a support, electromagnets carried thereby, each of said magnets comprising a substantially E-shaped bar including a middle leg and an inductance mounted upon the middle leg of each of said bars with the ends of the bars and the inductances arranged in opposed relation, means to fixedly secure one of the magnets to the support and spaced parallel slide rods fixed to the support and extending through the bar of the other magnet to slidingly sup port the latter.
In testimony whereof I affix my signature.
CARLOS L. JAUSS.
