FRANK ELLISON BEST, OF SEATTLE, WASHINGTON, ASSIGNDR TO FRANK E. BEST, IN C.,

Application led April 13, 1925. Serial N0. 22,778.
My invention relates to improvements in pin tumbler locks of the lock controlled assembly type in which a lock core may be removably locked within a lock housing by key operated means.
The object of-my invention is to provide a lock of this class having simplified means for locking the lock core within the lock housing, said means comprising a block arranged to be inserted between the key plug and the key plug housing, said block having a locking lug arranged to project outwardly through thekey plug housing to lock the lock core within a core case or housing.
Another object is to provide a lock of this class in which the usual sleeve that surrounds the key plug is replaced by a block `member of greatly simplified construction. The present invention ditferentiates from my prior Patent No. I1,38%,022 issued July 5, 1921 by dispensing with the sleeve that surrounds the key plug and using in place thereof a block or segmental locking member that is inserted in a suitable recess in the housing alongside of the key plug.
@ther and more specific objects will be apparent from the following description taken in connection with the accompanying drawings.
In the drawings Figure l is a view in longitudinal section substantially on4 a broken line 1-1 of Fig. 3 of a pin tumbler lock constructed in accordance with my 1nvention, showing the tumbler pins aligned by a key on one shear line so that the key plug may be rotated to perform the usual locking function. E
Fig. 2 isa similar view showing the tumvbler pins aligned on a second shear line so that a locking member may be operated to lock the lock core into, or unlock said lock core from a case or housing.
Fig. 3 is a sectional view substantially on broken line 3-3 of 1 showing the locking member in an engaged or lock position relative to the core case or housing.
Fig. 4 is a similar view showing the locking member in a disengaged or unlocked position.
Fig. 5 is a detached isometric view of the key plug housing. n
Fig. 6 is a detached isometric view of the locking member.
Fig. 7 is a detached isometric view showing one half of the core housing or case kend above the bore 9 and has a slot 14 that vextends inwardly from `the same end leaving an opening from the recess 13 to the outside of the housing 8 alongside of the extension 12.
The recess 13 is shaped to receive a lockingblock 15, Fig. 6 having a locking lug j 16 that extends outwardly through slot 14. The block 15 is curved both on the inside and the outside to fit the curvature of the key plug and the curvature of the wall of recess 13 both of which are arcuate with a center of curvature at the center of the bore 9. The block 15 is of less width than the slot 13 so that space is afforded for rotary movement of said bloc-k within housing 8 through an angle of substantiallyfifteen degrecs.
The key plug 10 is provided with a longitudinally disposed key way 17 for 1rthe reception of keys 18 or 19, and has dlametrically arranged tumbler pin receiving holes 20 arranged to register with the tumbler pin receiving holes l2 in the key plug housing 8. The key plug 10 has a head 21 at the front. end and is provided at the rear end with a throw member `22 whichy also. serves as a key stop vand as a means for preventing removal of the key plug.
The lock core, comprising housing 8, key plug 10, and block 15, is arranged to be inserted into a core case or housing 26 that has a shoulder 27 behind whichthe locking gate 16 may engage when it is inthe position shown in Fig. 3. The core case 26 is shown as a cylindrical housing but itmay be of any desired external shape so long as the receptacle in the same is shaped to receive the lock core and to afford a shoulder for cooperating with the locking lug 16.
A face plate 28Y is rigidly secured. to the housing 8 and forms a seat for the head 21 on the front end of the key plug.
By insertion of the key 18 the lock isoperated in the usual manner to perform the usual locking function while by insertion of key 19 the block 15 and locking lug 16 may be turned far enough to engage lug 16. with, or disengage lug 16 from the shoulder 27 thus permitting theI lock core to' be quickly and easily locked into, or released and removed from, core case 26.` In the usual operation of the lock the block 15 is locked relative to the housing 8 by the two end tumbler pins 23 as shown in Figs. Y1 and 3. The block 15 is herein shown as being long enough to have two tumbler pin stacks pass therethrough, but it will be understood that the length ot' said block may be varied so that one or more tumbler pins, as desired,
`may pass through said block.
The use of the block 15 eliminates the necessity for providing a relatively thin, accurately made sleeve around the key plug 15 hls simplifying the construction of the In the appended claims I have used the term block or segmental locking member to designate the part 15 and to differentiate said part from a sleeve, it being understood that the block or segmental locking member is not a sleeve and does not extend around the key plug but is only a segment that is interposed between the key plug and the housing.
The foregoing description and accompanying drawings clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that numerous changes in the device may be made within the scope and spirit of the following claims.
