IMPROVEMENT IN TIME AND 'PERMUTATION LOCK COMBINED.
Specification forming part of Letters Patent No. 182,154, dated September 12, 1876; application 'filed November 18, 1875.
To all whom itmay concern:
Be it known that I, CHARLES 0. Brass, of Norwich, in the county of New London and State of Connecticut, have invented an 1110-.
provement in Locks, of which the following is a specification:
'In Letters Patent No. 156,906, heretofore granted to me, there isa range of circular tumbler-r'ings upon disks that are clamped together by a screw-nut having a fork .or lever. In my present invention make use of the same kind of tumblers, but I have'modified the hook-ended stops, and I construct each screw-clamping nu-t with two notches, operated by the swinging keys, each having two pins, that give such nutsa more extended turning movement than in aforesaid patent, and more thoroughly loosen the parts. I also employ a peculiarly-constructed lifting-pawl upon the bolt-dog, and a jack upon the liftinglever, in combination with the fence-lever, the
parts being constructed so that the jack does not reach the pawl, except when the notches of the tumbler receive the fence, and when the movement of the main lever takes place, the fence is moved away from the tumblers. I also employ a balanced latching-lever, that connects the bolt to the cams upon-the spindle of the handle, and depress this latching-lever by a finger projecting from the bolt-dog, so
that the latching-lever remains out of action,
until the bolt dog is raised hence force cannot be applied to the bolt until all the other parts of the lock are in their proper position.
The time mechanism that is combined with this look is constructed so that the fence is prevented by a pin from moving toward the tumblers until the time arrives when the clock mechanism removes that pin and allows the fence to press against the tumblers. The
movementof the boltin locking or unlocking spindle, and front plate removed. Fig. 2 is av diagram showing the main lever, jack, and
pawl of the dog. Fig. 3 is across-section, I
showing the relative positions of the levers, bolt, and time mechanism; and Fig. 4 is a view at the rear of the lock, showing the time mechanism.
The lock-case a is provided with afront plate, a that is removed in Fig, 1, and to this plate a the spindle and handle are connected, and also the dials or pointers of the usual character, and upon the inner end of the spindle are the bolt-cams b, (seen in Fig. 2,) that serve to raise the arm b of the main lever, and also to connect with the latch-lever W, for projecting or retracting the bolt. There are also upon the inner end of the spindle the stubs 45, that act upon the rocking stop 16 of the circular tumblers, and there are similar stubs, 45, upon the back of one tumbler, taking the rocking stop upon the next tumbler.
By reference to the plan, Fig. 5, the operation of these stubs and stops will" be apparent. The distance between one stub and the next is ,less than the length of the swinging stop; hence, when the tumbler or spindle is turned one way, the incline of one stub first presses back one end of 16, passes over the same, and then presses back the other end of 16, throwing the first end into the notch of the next stub,so that the two will move reliably it the finger d,.that,ordinarily, presses upon this latch-lever b and keeps itdown until all the other parts of the lock are in position for the dog to be raised; hence the latchlever b cannot be brought into position for the spindle-cams to act upon the same, or for any end motion to be given to the :bolt, until the lock is ready to be opened.
Thereare segmental projections. 4 and 5 It will be apparent that two or more time movements might be-applied so as to act upon the link 41 or lever 12. They, of course, would require to be wound to the same extent each time thelockis set; butifone ofthe movements should accidentally stop,'either of the others would act to liberate the locking mechin combination with the dog d and jack substantially as set forth.
5. The nut 10, with the fork 27 and notch 28,
in combination with the stationary key t and its pins 29 and 30, as and for the purposes set forth. r
6. The lever 0, with the pins 37 and 38, inv combination with the clock-movement, the fence 6 and the double inclines 0 upon the bolt, substantially as set forth.
7. The spring starting-finger 46 for the balance, operated by the movement of the lockbolt, substantiallyas set forth.
Signed by me this 13th day of November, A. D. 1875.
CHARLES G. BLISS.
