KNOB OR HANDLE LOCK.
Application filed; December 24, 192 6. Serial No. 156,797.
My invention relates to locks, and has special reference to knob or handle locks.
An object of the invention is to provide a novel and improved lock of this character.
Another object of the invention is to provide a lock of this character which is simple and durable in construction, and reliable in use.
Another object of the invention is to provide a lock of the character indicated in which the lock bolt is moved automatically when the handle reaches a predetermined position to look the handle from turning movement.
Another object of the invention is to provide a lock of this character in which the key may be inserted and removed either when the handle is in locked or unlocked position.
The several features of the invention, whereby the above mentioned and other ob jects may be attained, will be clearly understood from the following description and accompanying drawings, in which:
Figure 1 is a front elevation of my improved lock and a portion of a cabinet door to which it is applied, the door having a three-point latching device with the parts thereof shown in latched position;
Fig. 2 is a rear elevation of a portion of the door illustrated in Fig. 1 but showing the parts of the latching device in unlocked position; v
Fig. 3 is a sectional view, partly in elevation, taken on the line 3-3 of Fig. 1;
Figs. 4, 5 and 6 are transverse sectlonal views taken on the lines 44, 55 and 6-6, respectively, of Fig. 3;
Fi 7 is a view corresponding to Fig. 3
but s owing the operative parts of the lock" in unlocked position;
Fig. 8 is a transverse sectional view taken on the line 8-8 of Fig. 7;
Fig. 9 is a sectional view taken on the line 9-9 of Fig. 2; and
Fig. 10 is a transverse sectional view taken on the line 10 -10 of Fig. 9.
My improved lock is shown applied to a cabinet door 2 having a. three-point latching device of a common construction. As shown this latching device is provided with a rotatable hub 4 having a laterally projecting lug or latch-bolt 6 and latch bolts 8 that are in the form of flat rods having their inner ends pivotally connected with ears on the hub 4 and their upper ends extended through and guided by straps secured adacent the upper and lower edges of the door, the strap for the upper bolt 8 being shown at 10. With this type of three-point latching device upon turning the hub 4 in one direction the latch bolt 6 may be swung beyond the longitudinal edge of the door, and the latch bolts 8 projected beyond the upper and lower edges of the door so as to latch the door, as shown in Fig. 1, and upon turning the hub 4 in the opposite direction the three latch bolts. may be retracted as shown in Fig. 3.
As shown, the lock is provided with an escutcheon or rose 12 which, when used in connection with a three-point latching device as above described, is secured by screws 13 on the front side of the door opposite the hub 4, and is further provided with a knob or handle 14 having a cylindrical shank that extends through and is mounted for turning movement in the rose 12. The inner end of the handle shank is provided with a reduced portion 15 forming a shoulder 16 that is arranged adjacent a shoulder 17 on the inner cylindrical wall of the rose. The rear end of the shank is provided with a rearwardly extending spindle 18 which is square in cross-section and extends through a clear ance opening in the cabinet door 2. The hub 4 of the three-point latching device is mounted on the spindle 18 and is held thereon by a lock-nut 19 which holds the hub against the rear side of the door. With this construction it will be apparent that by turning the knob or handle 14, the three latch bolts of the latching device may be projected and retracted into and out of latching position, as above described.
The shank of the handle 14 constitutes the cylinder of a pin tumbler lock having the usual pin tumbler chambers 20, and a keyoperated plug 22 axially mounted therein. This plug 22 carries pin tumbler sections 23 and is provided with the usual key slot 24 for receiving a key 25. A stop screw 26 is screw-threaded through an aperture in the cylindrical handle shank, and the key-operated plug is provided with a slot 27 which receives the inner end of the screw, the turning movement of the key-operated plug into and out of operative position being limited by engagement of the end walls of the slot 27 With the screw 26. A stud or pin 28 is secured in a' socket in the rear end of the key-operated plug, and has its rear end arrangedreccentrically to the axis of the plug and received in a slot or notch 30 in a lockbolt 32 which extends through a transverse aperture in,the reduced portion of the handle shank. When the handle is in door latching position, as shown in Figs. 1 and 3, one end of the bolt 32 isadapted to enter a locking notch 34 in the escutcheon or rose so as to lock the handle from turning movement, and thus the bolts of the three-point latching device are held in latching position. To unlock the lock, the key-operated plug 22 is given a quarter turn in a clockwise direction which, through the eccentric pin 28, acts to shift the lock-bolt 32 to retract its end from the locking notch 34, whereupon the handle may be turned to release the latch bolts of the three-point latching device and the cabinet door maybe opened.
Except as hereinafter described, the parts above referred to may be and preferably are the same as the corresponding parts of the lock described and claimed in my pending application, Serial No. 48,040, filed Aug. 4, 1925, to which reference may be had for a full and complete description of the same.
In my present construction means are provided so that if the handle has been turned to release the latch the key can be returned to its initial position relatively to the handle and, if desired, withdrawn, and the handle may thereafter be returned to its latching position, as shown in Figs. 1 and 3, whereupon the lock bolt 32 will be shifted automatically to project its end into the locking notch 34 thus locking the handle. To provide for this the notch or slot 30 in the lock bolt is elongated to permit the key and plug 22 to be returned to initial position without throwing the bolt, thus permitting the removal of the key when the handle is in unlatching position, and a coiled spring 36 interposed between the rear end of the lock bolt and an abutment plug .38 secured in the aperture in the handle shank in which the bolt is mounted. This spring projects the bolt into locking position independently of the plug 22- when the handle is returned to latching position with the key removed. The pin 28 when the bolt 32 is retracted by the key engages the rear. end of the slot and is on a dead center as shown in Fig. 8, so that the bolt is held retracted mechanically even if the handle is in latching position. For this reason, when the bolt is fully retracted by the key, the key does not have to beheld in order to permit the handle to be turned. The outer end of the abutment plug 38 projects into an elongated slot 40 in the escutcheon or rose 12 so that the plug by engagement with the end walls of the slot 40 limits the extent of the turning movements of the handle into and out of locking position.
With this construction it will be apparent that when the key and plug 22 have been returned to initial position relatively to the handle so that the pin tumbler sections are in alinement, the eecentricpin 28 is moved away from the rear wall of the slot 30 and bolt 32 and the plug is held against turning relatively to the handle by the pin tumblers, and if thereafter the handle is turned in a counter-clockwise direction to latching position, the abutment plug 38 by engagement with one end wall of the slot 40 insures the lock bolt 32 being positioned in alinement with the locking notch 34, and when the lock bolt reaches said position, the key having been removed, the coiled spring 38 acts immediately to snap the lock bolt into the locking notch. WVhen the key 25 is inserted in the key-operated plug 22 to unlock the plug and the plug is turned in a clockwise direction by means of the key, the eccentric pin 28, by engagement with the inner end wall of the notch 30, retracts the locking bolt from the notch 30, thus permitting the handle to be turned in a clockwise direction to unlatch the door. When the pin tumbler sections carried by the plug are out of alinement with the pin tumbler chambers 20, the key cannot be removed. The lost motion connection between the key operated plug and the lock-bolt 32, due to the length of the slot 30, however, permits the plug to be turned back so as to reposition the tumblers in the plug in alinement with the tumbler chambers in the handle shank, whereupon the key may be removed, the set screw 26 by engagement with one end wall of the slot 27 limiting this movement of the plug. When the key is thus removed the plug, of course, will be locked to the handle by the pin tumblers, but as the lock-bolt 32 is out of alinement with the locking notch 34, the handle is free to be turned with the plug to locking position. Thus another advantage of applicants construction is that the key may be removed, and inserted either when the handle is in locked position or when it is unlocked.
As will be evident to those skilled in the art, my invention permits various modifications without departing from the spirit thereof or the scope of the appended claims.
