LOCKING PLATE r03. CYLINDER Lo cxs.
Application filed April, 18, 1925. Serial No. 23,601.
To a ll, it may concern Be it known that I, J AMES E. Pmnmrs, a citizen of the United States, and a resident clamped more er less rigidly in place by the screws 7. In the present invention it is aimed to provide means for positively preof the city of New York, borough of Manwenting the rotation of the tumbler struchattan, in the county and State of New York, have invented a new and Improved Locking Plate for Cylinder Locks, of whichthe following. a full, clear, and exact description.
cylinder locks and has for an object to pro This invention relates to locking plates for vide an improved construction wherein the cylinder-lock is positively held in position so that it cannot be turned by a screw driver or other instrument to produce an unauthorized opening.
Anotherobject of the invention is to provide a locking plate wherein the cylinder lock is held against/rotation andwherein the plate acts as the ornamental outer member for the cylinder and at the same time as .means for resisting the action commonly known as jimmying.
A still further object of the invention is to provide an ornamental plate for use with,
cylinder locks which will not only present a pleasing effect but which will prevent the rotation of the look by a. screw driver or pliers. 1
In the accompanying drawings Figure 1 is a longitudinal vertical sectional view through part of a door and jamb and a plate embodying the invention, the
same being associated with a well known cylinder lock.
Figure 2 is a fragmentary front view of the door, plate and'cylinder lock shown in Figure1.,-
Figure 3 is a fragmentary front view of the plate shown in Figure 2.
Figure 4 is a sectional view through Figure 1, approximately on line 4-4. a a
Figure 5 is a fragmentary sectional view similar to Figure 1 but showing how a difi'erent form of lock may be used.
Referrin to the accompanying drawing by numera s, 1 indicates a door of any desired kind and 2 the door jamb provided with the usual strip 3. Associated with the 1 door 1 is the usual lock 4 having the tumbler structure 5 which is adapted to receive the key in the keyhole 6 whereby the bolt of the lock may be withdrawn at any time. Here.
hire 5 and in carrying out this idea a new plate 8 is presented, said plate having the tially as shown in Figure 3 whereby projectmg sections 12, 13, 14 and 15 are presented. Preferably, these are arranged so that the tumbler web 16 of the tumbler structure 5 fits into the opening 17 between the projections 12 and 13. This will prevent any rotation of the tumbler structure 5 independent of the plate 8. The plate 8 is i made sufiiciently long to have its forward edge 18 extend to a position almost in contact with the jamb 2 while the flange l9 overlaps the trimming strip 3.
If an unauthorized person inserts a screw driver intothe key openin v6, the tumbler structure 5. cannot be bodily rotated because of the plate 8 and particularly because of the action of the flange 19 and the edge 18. Also heavy pliers cannot -,be used to grip the bead 10 and rotate the same and the entire tumbler structure 5 which has been the case sometimes where there is no plate 8. In addition to preventing the rotation of the entire tumbler structure 5, the plate 8 prevents forcing the door by a jimmy or other prying implement;
In order to insure a ainst jimmying a look, a T-shaped metallic member 20 is pro- 2 and beyond the same to the keeper 22 of 1 lock 4. If desired, the keeper 23 may be secured to the body 21 by screws or other means though this is not always necessary. An aperture 23 is formed in the body 21 so as to permit the bolt from "lock 1 to readily project through the body" 21 into the keeper 22.
Under some circumstances a different form of lock to lock4 is desired, as for instance,
a segal look? In locks this kind the keeper 24 is p rovidedwith one or more apertured loops 25 for receiving a vertical bolt.
'An inwardly extending flange 26 projects connected to the body 21 of the T-shaped member 20. In case the jamb 2 was wider than that shown in Figure 5, plate 28 would be removed and another plate of the proper width substituted.
What I claim is:
1. A- locking plate, comprlsing a plate for receiving and holding against rotation a cylinder lock, means presenting a flange overlapping the janib strip when the plate is in use, said dplate being also formed with an edge exten ing to near the jainb whereby the plate cannot be rotated,
2. A locking plate for preventing the rotation of cylinder locks, said locking plate comprising a fiat body having near one end an upstanding flange, the flange extending substantially parallel to the end of the plate, said body being also provided near the opposite end with an annular bead merging at its base into an inwardly extending flange whereby a pocket is provided for the outer ga /ease end of a cylinder lock which is adapted to extend through the opening provided by said last mentioned flange, said last mentioned flange being formed with a plurality of radially inwardly extending sections whereby the. opening between said sections will substantially conform to the banel of the cylinder lock.
3. The combination with a lock, of a pair of locking plates, one engaging the key receiving mechanism for preventing its movement and the other engaging the lock casing, said plates overlapping at the point the door meets the jamb whereby a prying instrument cannot be inserted between the door and jamb.
4. The combination with a lock, of a pair of plates co-acting therewith, one plate engaging the key receiving structure for preventing any unauthorized shifting thereof and the other plate being connected to the door jamb and to part of the lock casing, the first mentioned plate having a flange near one edge and the second mentioned plate having a T-shaped head, one part of the head overlapping the first mentioned plate and extending to a point near said flange.
