" Patented July 5, 1938 , 2,123,107 UNITED STATES PATENT OFFICE 2,123,107 LOCKING MECHANISM FOR BUILDING STRUCTURES Steve J. Hodos, San Francisco, Calif. Application March 3, 1937, Serial No. 128,762 3 Claims. (Cl. 292-33) This invention relates broadly to improvements in locking mechanism for’ building structures and has particular reference to a combined motor operated and manually operated locking means 5 which functions to lock the doors of banks and like places wherein considerable cash is kept on hand to prevent the escape of burglars who enter these structures with intent to burglarize the same. ’ The principal object of the invention is to pro vide a locking mechanism for bank doors and like structures which may be either remotely con trolled by a motor operating mechanism or that may be manually controlled within the struc ture. Another object of the invention is to provide a combined motor controlled lock of the class described that will instantly lock either double or single swinging doors from a concealed point 20 preferably in the ?oor below the door or doors. A further object of the invention is to provide a locking mechanism of this type that may be operated from an enclosure such as an adjoin ing vault or it may be remotely controlled from CA either the inside or the outside of the structure. A still further object of the invention is to pro vide a locking mechanism of the class set forth that is positive in operation, is comparatively simple in construction and that may be installed b: O in any structure. Other objects and advantages of the invention will become apparent with reference to the sub joined speci?cation and the accompanying draw ing in which:--- o: 01 > Figure 1 is a sectional diagram of my improved locking mechanism as it would appear installed in a' banking or other structure and showing the operating motor and manual control arranged in a vault within the structure; Figure 2 is an enlarged sectional detail showing 110 one of the cam operated locks in locked position beneath one of the doors of the structure; and Figure 3 is a transverse section of the same , taken on the line 3-3 of Figure 2. In banking and like structures employing my system wherein swinging doors are utilized and a burglar enters these swinging doors, said doors may be readily locked so that when he once enters the structure he is imprisoned therein until the oi?cers arrive. This system includes swinging doors 5 and 6 hinged in the structure ‘i in the usual manner, as shown in Figure 1. These doors are provided with ?xed cam members 8 and 9 arranged cen trally thereof and under the bottom edges, as clearly disclosed in Figure 3. The cams 8 and 9 are convex and are positioned in slots l0 formed in the floor H and mating locking cams l2 and i3 are arranged upon rods 14 and I5, said cams l2 and I3 being ?xed to the rod l4. These cams l2 and I3 being concave and arranged to move laterally of the cams 8 and 9 from central neutral positions to locking position which locking position is shown in Figure 10 2. In this manner a wedging action is effected so that the cams 8 and 9 are locked to the cams l2 and 13 thereby locking the doors against move ment on their hinges. _ The mechanism for operating the cams l2 and 15 I3 thru the action of the rod l4 comprises a mem ber 16 operated by the motor l1, pinion l8, and rack l9 meshing with said pinion l8 so that when the motor is energized thru the medium of the battery 2|] and its circuit and when the switch 20 2| is closed, the rod I4 is moved to operate said cams l2 and I3 relative to the cams 8 and 9, the element l5 acting both as a guide and a conduit to carry the circuit wires. theRemotely circuit and located mayswitches be utilized 22 are to energize includedthe in motor I1 from either the inside or the outside of the structure. Suitable bearings 23 are posi tioned upon a sub-?oor 24 arranged under the structure floor H and house the rod l4 and the 30 conduit 15, and conduit merely acting as a guide and prevents turning of the rod I4 ‘and the cams l2 and I3. - A manual control lever 25 is also operatively connected to the motor shaft and may be used to 35 operate the device in case the circuits are ren dered useless by the cutting of the wires. In Figure 1 of the operating mechanism has been shown enclosed in a vault 26 or other suit able enclosure within the structure as in a bank. I claim and desire to secure by Letters Patent of the United States the ‘following; 1. A device of the class described comprising means capable of being installed in a building structure having swinging doors, comprising ?xed cam means positioned on said swinging doors, additional cam means cooperating therewith to lock said doors, and motor driven means for ac tuating said second cam means. 2. A device of the class described comprising means capable of being installed in a building structure having swinging doors, comprising ?xed cam means carried by said doors and movable cam means cooperating therewith to wedge said ?xed cam means when moved relatively thereto, 55 2 r " 2,123,107 and motor mechanism associated with said mov able cam means to cause said wedging action. 3. A device of the class described comprising means capable of being installed in a building structure having swinging doors, comprising ?xed cam members mounted under said doors and movable cam members associated therewith and ‘capable of Wedging said ?xed cam members against movement to lock the doors, a motor ac tuated means for operating said movable cam members from neutral positions to locking posi tion, and a remote control for said motor. ‘STEVE J.
