* LOUKQ (ModeL) Patented-Mal 25, 1884.
NITE STATES PATENT TFICE FRANK MIX, OF N ElV BRITAIN, CONNECTICUT, ASSIGNOR TO THE CORBIN CABINET LOCK COMPANY, OF SAME PLACE.
LOCK.
SPECIFICATION forming part of Letters Patent No. 295,660, dated March 25, 188 4.
' Application filed December 31, 1883. (Model) To (tZZ whom it may concern.-
Be it known that I, FRANK W. MIX, a citizen of the United States, residing at New Britain, in the county of Hartford and State key locks, and has for part of its objects the adjustment of the fence and tumblers to fit different keys, and to prevent a readjustment of the tumblers from interfering with the opera tions of the master-key. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a front elevation of my lockwith the cap removed. Fig. 2 is an enlarged horizontal section of said lock on line 00 w of Fig. 1, .looking down. Fig. 3 is an enlarged horizontal section of the same on line 3/ y of Fig. 1, looking up. Fig. 4 is a front elevation of my lock with cap removed, and with the bolt and tumblers represented in the position in which they are found after the bolt has been forced inward by the master-key. Fig. 5 is a front view of the master-key tumbler and bolt, the other tumblers and bolt proper being removed.
' Fig. 6 is a front view of the bolt proper. Fig. 7 is a front view of the master-key bolt or slide.
Fig. 8 is a side View of one of the individual keys, and Fig. 9 is a side View of the masterkey.
A designates the lock-plate, which is chambered on its back sufficiently to admit the master-key bolt or slide B, and permit it to slide lengthwise therein a distance equal to the stroke of the boltproper, C. Around the hole in the lock-plate in which the ordinary slotted hub, D, is placed, there is an annular recess, a, to allow the master-key bit I) to revolve. The master-key bolt B is slotted longitudinally at c, and a post, d, rigidly fixed in v the lock-case, extends through said slot and far enough in front of the bolt to pivot the tumbler e thereon, or a set of tumblers, if desired. The tumbler or tumblers and the bolt will be fitted to each other with slot and fence, so that the bolt will be held in place as in other locks. As shown, the fence is on the tumbler e, and the shoulders and slot on and in the bolt 13. The master-key bolt is notched on its I by the key, as in other locks.
lower edge to form talons for being acted upon I also affix to this master-key bolt the tumbler-post f, so that it necessarily moves with said bolt, and upon which post the regular tumblers g are mounted. The tumblers for both bolts are of course acted upon by springs in the ordinary manner. I prefer to make the master-key work so that its front side will be nearly in the same plane as the inner face of the lock-plate A, as shown. The thin part of the lock-bolt C lies between the tumblers g and the masterkey lock-work, and is therefore slotted at h, Figs. 2 and 6, to allow the tumbler-post f to pass through the bolt, and to permit the bolt C to movelongitudinally while said post f and the tumblers g are held in a stationary position by means of the masterkey bolt and tumbler. The ends of the tumblers are slotted at I and the bolt is provided with a fence, Z. I make this fence adjustable by forming it of as many superposed plates as there are-tumblers,
and secure said plates to the bolt 0 by pins m m, which pass through vertical slots in said The position of these slots is indicated The first one of (See plates. by broken lines in Fig. 1. said plates is the shortest and is flat.
the under plate in Fig. 2 and upper plate in Fig. 3.) The next or middle plate is longer, with a flange or shoulder at its edge about as high as the thickness of the first plate. The next and last plate is still longer, with a flange about as high as the thickness of all the other plates, as shown. A set-screw, n, whose slotted headis exposed at the outer end of the bolt C, is brought to bear with its end on the flange of the first fence, as shown. If the plates are properly constructed, the pressure of this screw n on the first flange will bind all the parts of the fence together. By loosening the fastening-screw a the three members of the fencel will be loosened, and the fence and the tumblers may be set by a key of any desired bitting, and the screw again tightened to hold the fence in its adjusted position.
In unlocking the lock with its own individual key, the bits which correspond in position with the bits 0, Fig. 9, will lift the tumblers to the proper height to pass the'fence, and the bit 1) will throw the bolt, while the master-key lock-work is not disturbed at all.
The same key that unlocks the door should,
also look it again. When the master-key is used, the bit q, Fig. 8, lifts the tumbler, the bit 6 throws the master-key bolt inward, and at the same time the bit 12 engages the bolt proper, O, and throws it back with-the bolt B, but without lifting the tumblers g at all, said tumblers being carried bodily back on the post f, as shown in Fig. 4. It is evident, however, that it is not necessary to provide the master key with the bitp for acting on the boltproper, because the post f on the master-key bolt will strike the end of the slot in the bolt proper and carry it back.
I am aware that tumblers whose slots have been made adjustable to the fence, and vice versa, are old, an example of which may be seen in Patent No. 243,870, to Doremus, July 5, 1881; and I hereby disclaim the same. My,
lock is specially adapted for this class of locks, for the lock proper may be adjusted and readjusted indefinitely. The master-key will work just the same as before. This I believe to be a result never before attained in a master-key lock.
It is evident that my master-key lock mechanism is also adapted for use in a lot of locks each fitted for an individual key, even though the fence and tumblers are not made adjustable relatively to each other. When such an adjustment of the tumblers and fence is employed, I locate the fastening mechanism (which, as shown, is the screw it) at the outer end of the lock-bolt 0, so that it is wholly out of the way of the master-key mechanism. I
believe that no prior lock has had this fasttening mechanism so located.
I am aware that locks have heretofore been constructed in which the tumblers are carried longitudinally with the lock-bolt proper, said tumblers being first lifted by the key which throws the bolt, and the same is hereby disclaimed. My lock differs from'such lock, because the'lock-bolt proper and its tumblers are carried by the master-key bolt without lifting said tumblers, or in any way changing their relation to the fence.
I claim as my invention 1. The combination of a lock-bolt, the tumblers belonging thereto, the master-key bolt and its tumbler, and the pivotal post for the tumblers of the lock-bolt proper, mounted on said master-key bolt, substantially as described, and for the purpose specified.
2. The combination of a master-key bolt, means for holding it stationary, a main bolt, and tumblers thereof mounted upon and moving with the master-key bolt, substantially as described, and for the purpose specified.
' 3. The combination of thelock-bolt, the adjustable fence composed of a series of superposed plates, a bearing for said plates, and a clamping mechanism extending to and accessible from the front end of the bolt, substantially as described, and for the purpose specified.
4. The combination of the lock-bolt, its fence composed of superposed plates, with flanged or shouldered ends overlapping each other, and mechanism for fastening said fence by pressure upon said flanged ends, substantially as described, and for the purpose specified.
FRANK W. MIX.
