Application May 26, 1941, Serial No. 395,182,

19 Claims.

The present invention relates to electro-magnetically controlled locks and aims to provide a lock of the general character indicated which is particularly adaptable, but not to be limited to controlling the doors of an automobile or other means having multiple doors as will hereinafter be more fully set forth.

It is the main object of the present invention to provide an electro-magnetically controlled lock which is simple in construction, easy and economical to fabricate, assemble and install where needed, and admirably adapted to perform its intended functions.

In the accompanying specification there shall be described and in the annexed drawing shown an illustrative embodiment of the locks of the present invention. It is, however, to be clearly understood that the present invention is not to be limited tothe exact details herein shown and described for purposes of illustration only inas much as changes may be made thereinwithout the exercise of invention and within the scope of the claims hereto appended.

In the accompanying drawing,

Figure 1 is a side 'elevational view of an electro-magnetically controlled lock made in accordance with the present invention, the lock being shown in a locked position,

Figure 2 is a similar view of thesame in an unlocked position, and

Figure 3 is a partial top plan, partial longitudinal sectional view of the same, again in a locked position.

Before describing the invention in detail it is deemed desirable to point out some of the shortcomings of the means hither-to used for locking multiple doors, particularly in automobiles, and point out the manner in which the present invention overcomes and eliminates these shortcomings. For example, at the present time the doorsof automobiles are provided with individual locking means so that it is necessary when the operator leaves the vehicle to stretch back from the front seat and set the locking means for the rear doors. Likewise, when the operator enters the vehicle, if other persons intend to enter the same by the rear doors, it is necessary,- after opening the front door, to reach in and unlock the rear doors from the inside. The present invention provides a lock which eliminates these inconveniences; for, by means of the present invention there is provided a lock which can be installed in three of the four doors of a ve-' hicle, and all three can be controlled from a cen-' tral point, associated, for example, with the front door used by the operator. It is, of course, to be clearly understood that the operation of the presmagnetically controlled lock would be desirable. i Referring now in detail to the aforesaid illus-' trative embodiment of the present inventionand with particular reference to the drawing illustrating the same, the numeral 5 designates a plate-in whichthere is slidably mounted; a sliding bolt 6, the outer end of which is adapted to cooperate with akeeper (not shown), and which is normally maintained in the locked position shown in Figure l of the drawing by means of a spring I. The bolt 6, is adapted to be moved out of its locked position by means of a lug 8 cooperablewith a recess 9 111 the bolt, the lug being carried, on a shaft I31 adapted to be rotated by any desired key mechanism.

-Rotatably .mounted in the plate 5, adjacent the inner end of the bolt 6, is a shaft ll having fixed thereon a cradle I2 consisting of a hub l3. and arms 14 and I5 extending frompthe hub 'at right angles-to each other; Cooperable with the cradle l2, and partially-surrounding the same, is an arcuate flange it carried by the plate 5,. the arrangement being such that a weighted ball or detent H is retained in the cradle l2. Theflange I6 is provided with an opening l6 receptive of the inner end of the bolt 6. Depending from the underside'of each of the arms l5 and 16 are prolow the core 24 of an electro-magnet 25.

One end of the electro-magnet is grounded to the plate 5 by'means of a conductor 26. The other end of the electromagnet is co'nnectedby a conductor 27' to one side of the source of electric current 28. The other side of the source of electric current 28 is connected by a conductor 29 to a contact 30 carried by the plate 5 and insulated therefrom. Associated with the shaft 10 is a leaf contact- 3| adapted, when the shaft I0 is rotated by a key mechanism, to wipingly en gage the *contact 30 and thereby momentarily close the electric circuit'through the electromagnet 25. I

This completes the description of the aforesaid illustrative embodiment of thepresent invention and the operation thereof may be briefly summarized as follows:

It will be noted from Figure 1 of the drawing thatthe cradle I2 is in such position that the weighted detent ll is'supported on the arm i4 adjacent 'the inner end of'the bolt 6. ,In this figure of the drawing, the bolt is shown ini'ts locked position and until the weighted detent I1 is moved'out of the path of the bolt 6, the latter cannot be moved into an'unlocked position. Whenit is desired to" unlock the device a key mechanism (not shown) is operated to start the rotation of the shaft ID. This operation brings the contact 3| momentarily into engagement with the contact 30 thus completing an electric circuit through the electro-magnet 25. The electrical impulse to the electro-magnet 25 causes the attraction, with a snap action, of the lever 2| to the core 24 and this movement is transmitted, by virtueof the engagement of the cam 20 with the projection Hi to the cradle I2. The latter is rocked thereby, throwing the weighted detent I! over into a position resting upon the other arm 15 of the cradle, as shown in Figure 2 of the drawing. Of course, as soon as the contacts 3| and 30 are separated, the lever 2| returns to its normal downward position and the continued rotation of the shaft I0 of the key mechanism through the engagement of the lug 8 in recess of the bolt 6, permits the bolt to be moved out of engagement with its keeper (not shown). It will be noted that the latter action is permitted to take place by reason of the fact that there is no longer any obstruction in the path of the inner end of the bolt 6. The next time that the key mechanism is operated to rotate the shaft 10, the reverse operations take place; that is, the bolt may be moved into its locked position, immediately followed by momentarily charging the elec tro-magnet and thereby returning the cradle and the weighted detent carried thereby to the original position shown in Figure 1 of the drawing.

This completes the description of the operation of the mode of use of the present invention. It will be noted from all of the foregoing that there is provided by means of the present invention an electro-magnetically controlled lock which is simple in construction, easy and economical to fabricate and assemble and admirably adapted to permit its intended functions.

In order to adapt the lock of the present invention to the situation above described in connection with the multiple doors of an automobile, a lock of this type is installed at each of the doors except one and it is the key mechanism at that one door that controls the flow of current to the electro-magnets.

Other objects and advantages of the device of the present invention will be obvious to those skilled in the art to which the present invention relates.
