18 Claims.
This invention relates to certain new and useful improvements in looks and refers more particularly to key actuated tumbler locks.
It is an object of this invention to provide a look of the character described, in which the lock cylinder has both axialand rotational movement with respect to its mounting member.
Another object of this invention is to provide means whereby, at the completion of the projection of the lock cylinder axially into the mounting member, the lock cylinder is automatically turned to its locked position.
Another object of this invention resides in the provision of common means for projecting the cylinder from the mounting member upon rotation thereof out of locked position and for turn ing the cylinder to locked position at the completion of its projection into the mounting member.
A further object of this invention is to simplify the construction of a lock in which the Lock cylinder has both longitudinal movement and rotation and to reduce the number of its parts.
With the above and other objects in View which will appear as the description proceeds, this invention resides in the novel construction, cornbination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.
In the accompanying drawing, one complete sample of the physical embodiment of this invention is illustrated constructed according to the best mode so far devised for the practical application of the principles thereof, and in which:
Figure 1 is a side elevation with parts broken away and in section of a lock embodying this invention;
Figure 2 is a view similar to Figure 1, but illustrating the lock cylinder in its unlocked projected position;
Figure 3 is a cross section view taken through Figure l on the plane of the line 33;
Figure i is a detail section view illustrating the manner in which the tumblers of the cylinder are retracted upon forced projection of the cylinder into the mounting member; and
Figure 5 is a detail section view taken through Figure l on the plane of the line 5-5.
Referring now more particularly to the accompanying drawing in which like numerals indicate like parts throughout the several views, the numeral 5 represents a mounting member of any desired design, having bore 6 to receive a lock cylinder 7. The lock cylinder '7 is of conventional construction and has a plurality of locking-tumblers 8 yieldably urged by springs, not shown, to project one end outwardly beyond the cylinder and into a longitudinal groove 9 formed in the mounting member in communication with the bore 6, to normally secure the lock cylinder against rotation. The locking tumblers 8 are retractable out of the groove 9 to release the cylinder for rotation by the insertion of a proper key 10. At the innermost end of the lock cylinder is an extension or stem 11 which projects through an opening 12 in the closed end of the mounting member bore to provide a locking bolt or to afford a connection with mechanism, not shown, to be locked.
Surrounding this stem or projection 11 between a shoulder 13 formed by the inner end of the lock cylinder proper and the closed end of the bore 6, is a coil spring 14 which has both an expansive and torsional component. When the cylinder-is in its normal locked position illustrated in Figure 1, the spring 14 is compressed, storing up energy which-tends to project the cylinder outwardly of the mounting member bore.
The ends 15 and 16 of the spring are directed laterally to engage in apertures 1'7 and 18 formed in the closed end wall of the bore 6 and the lock cylinder shoulder 13 respectively, and the cylinder is at all times in such position of rotation with respect to the end 15 of the spring, as to place the spring in tension tending to turn the cylinder in a counterclockwise direction when viewed from its front end. 90
The movement of the lock cylinder within the mounting member bore is guided and limited by the engagement of a pin or lug l9 fixed to the cylinder inner end portion and projecting through an L shaped slot'Z0 formed in the mounting member. Obviously, this slot may be of but sufficient depth as to accommodate the height of the pin 19 or as in the present instance, it may extend entirely through the wall of the mounting member.
With the lock cylinder in its normally locked position depicted in Figure l, the pin 19 engages the end. of the transverse leg 21' of the slot and limits the rotation of the cylinder by the action of the spring 14. At this position the tumblers are aligned with the longitudinal locking groove 9 and upon withdrawal of the key 10 from the cylinder their springs project the tumbler ends into the locking groove and secure the cylinder in its locked position. Longitudinal movement of the lock cylinder is obviously impossible at this position of rotation as the transverse leg 21 of the slot 20 cooperating with the pin 19, prevents such movement.
To effect complete unlocking of the lock, and which necessitates the projection of the cylinder outwardly of the mounting member to its position illustrated in Figure 2, it is necessary to insert the key 10 and turn the cylinder in a clockwise direction against the action of the spring 14 until the pin 19 aligns with the longitudinal leg 22 of the slot 20. Immediately upon the alignment of the pin 19 with the leg 22 of the slot 20, the spring 14 projects the cylinder axially from the mounting member until the pin engages the outer end of the leg 22.
The longitudinal motion of the cylinder during its outward projection is sufiicient to position the innermost tumbler 8 at or slightly beyond the outer end 23 of the mounting member, and as best shown in Figure 4, the mounting member end 23 has its inner edge portion cut away as at '24 in alignment with the tumblers 8. It is observed that the cut away portion 24 has an inclined bottom and thus it is possible to move the lock cylinder into the mounting member bore against the action of its spring without the use of the key, inasmuch as the inclined bottom of the slot 24 cams the projecting tumbler ends into the body of the cylinder.
Hence, to return the'lock cylinder to its retracted position,-it is only necessary to force the same inwardly against the action of its spring as shown in Figure 4, and immediately upon the alignment of the pin 19 with the leg 21 of the slot, the tortional force of the spring 14 snaps the tumbler around to its fully locked position.
'From the foregoing description taken in con nection with the accompanying drawing, it will be readily apparent to those skilled in the art to which an invention of the character described appertains, that this invention provides an ex ceptionally simple means for obtaining both longit'udinal and rotational movement on the part oi a lock cylinder and that the simplicity of the design enables the lock to be built with comparatively few parts.
