LOCKING DEVICE Filed Sept. 2l, 1925 20 egress is allowed.
Patented Nov. 24, 1931 UNITED STATES PATENT OFFICE LOCKING DEVICE Rossum Application filed September 21, 1925. Serial No. 57,546.
Heretofore, on such vehicles, in order to lock the doors thereof, it has been necessary to voluntarily lock each door. This is usually done by operating a button or lever on the inner side of the doors except one of 1them which is then locked by means of a rey.
The present invention has among its objects the elimination of this method of locking in providing an automobile locking, system so that all of the doors may be locked simultaneously and automatically.
A further object is to so lock the doors that .while access to the interior is impossible, free -A still further object is to provide means for simultaneously unlocking all of the doors from the interior of the vehicle.
Another object is the means by which the preceding objects are accomplished.
With these and other objects in view as will be readily apparent to those skilled in the art, the invention consists broadly in a locking device for one or more movable parts ot' a vehicle adapted to be retained in unlocked condition during operation of the vehicle but which automatically locks upon the voluntary ending of the operation and also in means to again return the parts to unlocked condition if desired.
In the drawings the invention is illustrated as applied to a door lock, for example, for a door of a closed automobile, and the drawings show in Fig. 1 two door locks with the controls therefor; in Fig. 2 a section through line 2-2 of Fig. 1; Fig. 3 is an enlarged diagrammatic view of certain parts; and Fig.
4 is an enlarged section on line 4 4 of Fig. 1.
As shown, the device consists of a lock having a casing 10 in which slides a bolt 11 carried in suitable guides, one of which is shown at 12. At the rear end of the bolt 11 is a cross piece or-abutment 13 against which is adapted to act a double cam piece 14. This cam so piece has the two cam ends'15 and 16 so that it may be rotated either way and will operate the bolt and, further, is mounted on a square shaft 17 which extends through the cover for casing 1() and will be the shaft for a handle on the outside of the door (the cover, handle, and door not being shown).
The inner end of shaft 17 will be round as shown clearly in Fig. 2 and will serve as a bearing for the lower end of lever 20. The latter will have near its lower end on one edge a cam surface of a contour similar to or the same as that on cam 15 and will extend up to the upper edge of the door body so that bolt 11 may be operated by either the handle mentioned or the lever independently of the other. The round end of shaft 17 will also extend through a slot 21 in bolt 11, the shaft acting both as a guide and stop for the bolt, and will pass through the casing 1() and be secured in any suitable manner as by cotter pin 22. A suitable spring 23 will be used to return the bolt.
In addition to the parts mentioned, a second bolt 25 will also be mounted in casing 10 in suitable guides 26 and 27 and this bolt 75 is adapted to enter a slot 28 in the edge of campiece 14 and prevent turning of the latter. Bolt 25 will be impelled toward the slot 28 by a light spring 29 between guide 26 and a collar 30 carried by the bolt, and will be retained out of the slot by a latch 31 co-operating with a notch 32 in the bolt 25 when the latter is suiliciently retracted. This latch 31 will be pressed into the notch by spring 33 acting against a plunger 34 which in turn acts against latch 31. Latch 31 and plunger 34 will be'guided in and the former will act as the core of a solenoid 35. Latch 31 will be of magnetic material while the plunger 34 will be of non-magnetic material.
Further, there will be another Solenoid 40 surrounding the rear end of bolt 25 so located as to retract the bolt from engagement with slot 28 and a sufficient distance to permit engagement of latch 31 in notch 32.
In addition there will be provided in one of the locks a key operated barrel 41 carrying a linger 42 acting on collar 30 to retract bolt 25 a sufficient distance to disengage slot 28, but being prevented by a stop 43 from retract- ICO ing the bolt far enough to cause latch 31 to engage notch 32.
As indicated, solenoids 35 and 40 will be connected to the electric system of the vehicle, the former through a special ignition switch and the latter through a separate switch 45 located at any suitable place on the vehicle, for example, a simple spring button switch on the instrument board.
Solenoid 35 will be connected to ground at one side and to a contact piece 50 in the ignition switch on the other. Contact piece 50 and the other elements of the switch will be so constructed and arranged that the circuit through solenoid 35 will be closed only during the operation of turning off the ignition. This may be done by the means indicated in the drawings.
In a common type of ignition switch a disc 51 carrying three integral fingers 52, 53 and 54 is keyed or splined to a shaft 55 forming part of the operating lever (not shown). When this disc 51 is in the position shown in full lines, the fingers 52 and 53 are-in contact with two contacts 56 and 57 connected respectively to the ignition circuit and the battery, while the finger 54 acts merely to balance the pressure of the-other two. In the dotted position, finger 53 is in contact with contact 56 but the other two are not making contacts and the circuit is accordingly broken. l
For the .present purpose, contact 57 is extended laterally so that finger 53 maintains contact therewith after finger 52 has left contact 56, and contact 50 is arranged to co-act with finger 54 when the disc is moving in the direction of the arrow and before finger 53 has left contact 57. This may be accomplished by forming finger 54 with one edge turned up and the other down as indicated in Fig. 3 so that in turning off the ignition finger A54 passes over contact 50 and in turning on it passes under the thin piece of insulating material 60 upon which contact 50 is mounted, the numeral 80 indicating a depression below the insulating piece 60 permitting the actin just described.
While the device has been described with reference to a single lock it is obvious that it may beapplied to several locks on the same vehicle and this is contemplated. In fact, a second lock is indicated at similar in all respects to the other except that no key operated part need be used on but one of the locks on la vehicle as, when one door has been opened, switch 45 is accessible to unlock all of the doors simultaneously.
Further, in the form shown the locks will all, including the key operated one, remain in locking condition until the switch 4.5l is closed 'so that, ifv the operator desires for any reason to open with his key the one door, as soon as he shuts it again it locks, unless ,in the meantimehe has closed switch 45.
the interior 'of the vehicle. In this case, stop 43 will be so placed as to permit the finger 42 to move bolt 25 far enough to allow latch 31 to engage notch 32.
Also, the present device may be used in '75v conjunction. with the locking device for a control member described and claimed in application Serial Number 647,438., filed June 25, 1923, by the applicant and such use is in contemplation. If this is done, the, mere voluntary stopping of the engine by turning of the ignition will lock the particular control member and all of the doors instantaneously so that it will be impossible for the operator to leave without securing the car against unauthorized use. Y
While the invention has been described as applied to door locks, it is not to be considered as limited to this use. It may be applied 'with minor modification to any movable part, such as the hood, a spare tire lock, tool box, and so forth, any or all may be arranged to be locked when the ignition is cut off.
Having now described the invention and the preferred form of embodiment thereof, it is to be understood that it is not to -be limited to the specific details herein described and illustrated but only by the scope of the claims which follow:
