March 5, 1940. KA|sER COMBINATION SWITCH LOCK Filed March 29, 1939 2 Sheets-Sheet l v Inventor fau/cz/e/ A iiomeys P. KAISER March 5, 19-40.
V UNITED STATES PATENT, OFFECE COMBINATION sweet nook Paul Kaiser, San Francisco, Calif. Application March 29, 1939, Saar No..264,833 4 Claims. (organic The present invention relates to combination switch locks designed primarily for use in connection with the ignition switches of automobiles and other motor driven vehicles and has for its primary object to provide a theft-proof ignition lock to prevent unauthorized use of the vehicle.
A further object is to provide a slidably actuated switch for controlling the ignition circuit, together with a plurality of selectively controlled disks adapted to control the switch closing movement. l
A further object is to provide a switch of this character enclosed within a housing and providing interengaging locking means between the switch and the housing to prevent access to the interior of the housing.
A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a top plan view with parts broken away and shown in section.
Figure 2 is a vertical sectional View, and
Figure 3 is a bottom plan view of one of the control disks.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates the switch housing generally which includes a bottom 6 resting upon a flange I at the lower edge of an opening formed in the instrument panel 8 of the vehicle, the bottom of the housing being secured to the flange by means of bolts 9 extending therethrough. The housing 5 also includes a hinged cover it which extends over and forms the rear portion of the top of the housing and the cover also includes the back portion ll of the housing and is pivotally secured to the rear edge of the bottom 6 by pins H2. The front edge of the cover is provided with an upstanding flange |3 which is secured to the instrument panel by means of a bolt l4.
A metal conduit l5 communicates with an opening it in the bottom 6 of the housing through which circuit wires I! extend for attaching to terminals 18 carried by an insulated terminal block IS on the opposite side walls of the housing. Theterminals It also serve to secure a plurality of spaced contacts 20 with which a slidable contact member 2! is engageable to bridge the contacts 20 at the opposite sides of the housing to close the circuit communicating therewith. 5 The slidable contact 2! thus constitutes a switch and is secured on the inner end of a rod 22 slidably mounted in a bracket 23 positioned within the housing and projecting outwardly through the front end of the'housing and provided with a manipulating knob 24.
Also suitably secured to the rod 22 is a block 25 having a"'cross member 26 formed thereon adapted for entering notches 21 formed in a plurality of disks 28 freely mounted on a shaft 29 having its ends journalled in the opposite side walls of the housing.
The front of the housing is rounded as shown more clearly'in Figure 2 of the drawings, and provided with slotted openings 33 through which manipulating handles 31 project attached to the respective disks.
Suitably displayed on the outer surface of the housing adjacent each of the slotted openings is a dial 32 which may be either in the form of 25 numerals or letters, as shown in Figure 1.
A portion of the periphery of each of the disks 28 is formed with spaced recesses 33 with which a spring projected pin 34 is engageable to secure the disk in a predetermined set position.
The rod 22 is likewise formed with a recess 35 with which a spring projected pin 36 is adapted for engagement in order to secure the rod with the switch in its closed position.
As more clearly shown in Figure 2 of the draw- 35 ings, the under side of the cover Ill is formed with an eye 31 into which a pin 38 is insertable, the pin being carried on the upper end of an arm 39 rising from the block 25. Accordingly, when the rod 22 is moved inwardly to open the switch the 40 pin 38 will lock the cover H! so that unauthorized persons cannot open the cover to gain access to the interior of the housing.
Accordingly, in the operation of the device it will be apparent that it is necessary to manipulate the disks 28 in a manner to align the notches 21 in the peripheral edges thereof in order to accommodate the cross member 26 before the rod 22 can be slidably actuated to close the switch.
It is believed the details of construction and manner of operation of the device will be readily understood from the foregoing without further detailed explanation.
Having thus described the invention-what I claim is 56 1. In a combination switch look, a housing, a slidably actuated switch member, a plurality of selectively operable permutation members adapted to control movement of the switch member into circuit closing position, a hinged closure for the housing and cooperating means between the slidable switch member and the closure to secure the latter against opening movement when the switch member is in circuit opening position, said closure securing means constituting a guide to maintain the switch member in alignment for circuit closing engagement with the permutation members during circuit closing movement.
2. A combination switch lock comprising a housing, a switch member slidably operable therein, a cross member carried by said switch member for movement therewith and a plurality of permutation disks rotatably mounted in the housing and normaliy engaged by said cross member to prevent circuit closing movement of the .switch member and a notch formed in the peripheral edge of each of said disks adapted when aligned to accommodate said cross member to permit circuit closing movement of said switch member, said switch member being movable radially relative to said disks into and out of engagement with said notches.
3. A combination switch lock comprising a housing having a movable cover, a switch memer slidably operable therein, a cross member carried by said switch member for movement therewith and a plurality of permutation disks rotatably mounted in the housing and normally engaged by said cross member to prevent circuit closing movement of the switch member and a notch formed in the peripheral edge of each of said disks adapted when aligned to accommodate said cross member to permit circuit closing movement of said switch member, said switch member being movable radially relative to said disks into and out of engagement with said notches and a sliding locking bolt for the cover carried by the switch member to lock the cover when the switch member is in open circuit position.
4. A combination switch lock comprising a housing having a movable cover, a switch member slidably operable therein, a cross member carried by said switch member for movement therewith and a plurality of permutation disks rotatably mounted in the housing and normally engaged by said cross member to prevent circuit closing movement of the switch member and a notch formed in the peripheral edge of each of said disks adapted when aligned to accommodate said cross member to permit circuit closing movement of said switch member, said switch member being movable radially relative to said disks into and out of engagement with said notches and a sliding locking bolt for the cover carried by the switch member to lock the cover when the switch member is in open circuit position, said locking bolt constituting a guide for the cross member to enter the notches during circuit closing movement of the switch member.
