LOGKU Application filed June 16, 1922. Serial No. 568,832..

To all wiwm it may concern:

Be it known that l, EUGENE R. WEBER, citizen of the United States. residing at Rochester. in the county of Monroe and State of New York, have invented certain new and useful Improvements in Locks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon.

This invention relates to locks and more particularly to the variety having a rotary cylinder or plug extended through the wall portion or other supporting means to which a lock is attached to receive a key or other operating device, the chief object of the invention being the provision of simple and eflicient means for effectively preventing the cylinder or plug from being forcibly displaced for obtaining access to or disabling the lock. To these and other ends the invention resides in certain improvements and combinations of parts all as will hereinafter be more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Figure 1 is an exterior view of a door having a lock embodying the present invention supported on the interior side thereof;

Figure 2 is a sectional view on the line of Figure 3, showing the construction for securing the cylinder or plug against displacement from the door;

Figure 3 is an elevation of the parts shown in Figure 2 as appearing at the interior side of the door;

Figure 4 is a section on the line i a of Figure 2;

Figure 5 is a view of a door having a lock applied thereto embodying a modified form of the invention;

Figure 6 is a sectional View on the line 6 --6 of Figure 7;

Figure 7 is a sectional view on the line 7 of Figure 6 illustrating the construction shown in Figure 5 for securing the cylinder or plug against displacement.

Similar reference numerals throughout the several views indicate the same parts.

The invention is disclosed in the present instance, by way of illustration, as embodied in a lock of a variety particularly adapted for use on the closure or door of a safe deposit box, the door being represented in the drawings at 10, having the lock 11 secured to the interior side thereof in any suitable manner, for example, by screws 12. it has been found desirable to construct locks of this character with a cylinder or plug extending through an open.- ing 13 in the door to the euterior side of the latter for rotation by a key or other operating means. Ei'ecurity b0 doors of this type are commonly constructed of steel and. those desiring to forcibly open. the door for unauthorized purposes have heretofore found it possible in most instances to forcibly displace the lock plug, either by extracting the same at the exterior side of the door or by driving the plug inwardly through the lock, thereby securing access to the lock or disabling the same and thus unlocking the door.

The present invention provides an improved construction for effectively preventing the forcible displacement of the lock plug in this manner, while at the same time interposing no interference with the normal operation of the plug, or the authorized removal of the look from the inside of the door for repair or replacement. To this end either the wall of the opening 13 in the door which receives the lock plug, indicated at 14, or else the circumferential surface of the latter, or both, have formed therein an arcuate channel or groove 15 cooperating with means engaging the adjacent surface of the other member to secure the plug means against displacement while leaving it free to rotate in the opening 13. In the present instance this construction is given the form of a channel or groove 15 in the circumferential surface of the plug means for cooperating with ball means or members l6 engaging in a corresponding groove 17 in the wall of the opening 13 of the sup porting means. These opposing grooves thus form in effect a ball race which is substantially filled with the ball members 16, as shown in Figure 4:, effectively locking the plug means against displocement in either direction from the opening in the door. The balls 16 may be inserted, or removed, if necessary, after the plug means has been located in its opening in the door,

through a passage communicating with the hall race and opening exteriorly through a surface of the plug means or of the sup porting means or door inaccessible from the outside of the latter. Tn the preferred form this passage is shown at 18 formed in the plug means itself, having one end turned angularly into comn'iunication with the ball race. and the other opening at the inside of the plug and closed by any suitable means, such, for example, as the threadee stopper 19. In this case an additional ball 20 placed in the passage to prevent the balls in the race-way from entering the lat ter, except when the stopper 19 is removed.

To increase the difficulty of driving the plug inwardly of the door, the plug is preferably provided with an annular shoulder 21 cooperating with a similar shoulder in the sides of the opening 13. This increases the resistance of the plug to force applied to displace the same inwardly, it being more difficult to pull the plug outwardly of the door because of the difhcnlty of applying the necessary force thereto.

lVhile the plug means 1% described above may be constructed integrally with the cylinder or plug which extends through and operates the lock, it is preferred to form the plug in sections. That is to say the plug means 14- is preferably extended to a plane 21 spaced somewhat from the inner surface of the door, in abutting relation with the outer end of the plug 22 extending through the lock, these plug sections being separably connected for conjoint rotation by any suitable device, such, for example, as the dowel pins 23 in the plug means 1 engaging in corresponding openings 24 in the lock plug 22. By this arrangement the plug means 14 and the plug 22 rotate as one while the lock is in place on the door, and the lock may be readily detached if found necessary without removal of the plug means or section 14.. In the modification described above the parts are assembled by first placing the plug means 14% in position in opening 18 of the door and then inserting the ball members into position through the passage 18, which is then closed by means of the stopper 19. When the plug means has thus been secured in position, the lock proper may be attached to the door, the plug means 14: being rotated to bring its dowel pins 23 into registry and engagement with the openings 24 of the lock plug 22.

Various modifications in the specific embodiment of the invention have been contemplated; Thus in Figures 5 to 7 the walls of the opening 25 receiving the plug means. 26 and the circumference of the latter are provided the one with a circumferential groove 27 and the other with sockets 28 for the-ball members 29, the sockets in the present instance being formed in the plug stopper 31.

means, although, of course, this arrange ment might be reversed to locate such sockets in the supporting means or door 10. The passage 3 for inserting the balls 29 in this modification is arranged to open exteriorly through the end of the door, being closed by The plug means, as before, connected by dowel pins 32 with the plug of the lock, the parts being so disposed and arranged that when the lock is in place, the limited movement of its plug 22correspondingly limits the rotation of the plug means 26 so that the key opening 33 moves throughthe small angle included by the angular line c to prevent the ball members from becoming displaced from their sockets and entering the passage 30.

In the assembly of this modified construction the plug means 26 is located in its opening 25 in the door and the ball members inserted in their sockets through passage 30, the plug means being rotated to the proper position to receive the ball and the door'being tilted so that the balls drop through the passage by gravity. When the lockis then attached to the door with its plug 22 in engagement with plug means 26 the move ment of the latter-is limitedin the manner described, so that none of the ball members are brought during the operation of the lock suiiiciently into registry of the opening to permit the displacement of the balls, Figure 7 showing one of the limiting positions of movement. shown in the present instance in engagement with one of the movable parts for cooperation with a groove of the other it is obvious that elements other than ball members might be employed for this purpose. and plug means may of course be supported on the door frame or other stationary part instead of on the door.

The invention thus provides a. simple and practical construction for the lock plug -or cylinder, and door or other supporting \Vhile ball members have been loo The lock means for the lock, which effectively prevents access to or injury of the lock bythe unauthorized forclble displacement of the plug either outwardly or inwardly of the door. while the lock' proper may be as readily assembled or detachedas' before.
