'I'u all whom it may concern:

Be itknown that I, HENRY LEWIS RUssELL, hl'Bloomingtoiuin the county of McLean md .tate of Illinois, have invented certain new nd useful Improvements in Indicator-Locks; hid I do hereby declare the following to be a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same,'reference being bad to the accompany ing drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object T" m y llIVBDiiiOIllS to provide a,

look especially designed for fire-alarm boxes,

railroad-switches, &c., where it may sometimes be desirable to know who unlocked it last, that must be opened with numbered keys, and will register the number of the key that :0 last unlocked it; and to this end the invention consists, essentially, in the combination,

with the locking mechanism of a lock, of registering mechanism for registering or indicating any one of a series of differentlyformed 2 and indicated keys, which operates both the locking and registering mechanism in unlocking the lock.

It further consists in certain novel combinations of devices and in peculiar constructions of parts, which will hereinafter specifioally be designated.

Referring to the accompanying drawings,

i 1879. Fig.12 represents key No. 9999. Fig. 13 represents a key-blank marked to indicate the system of construction.

The lock is provided with the usual bolt A, which is held in its horizontabplane by the yoke a and pin b, and is thrown and held out by the spiral spring B and bent springs B. It is also provided with three ring-tumblers, O, that are secured at c, to t e inside i the rim of the case, whose free slotteden s set over the boss d, which pro'ectsupward from the lever D, that is pivotdd at f,'and .with three slides, E, that are held in place over the bolt A, with their pointed upper ends, g, engaging in corresponding holesg'in the tumblers O by the pins k! and i, thatpass through their slots and are secured in the, front plate of the look. When a key is inserted in the lock and turned it will come in contact with the lower edge of one or mone of these slides E,and cause it or them to move the tumblers to release the boss d from the shoulder or shoulders k, and hold them there until the key, in itsfurtherturning, is brought against the lever D, which engages with the stud lon the bolt A, and presses itback until the bolt is drawn in.

to their original position.

Though the efl'ects produced by the action of the above-described parts resemble those of corresponding parts in other looks, it will be seen that there is much novelty both in construction and arrangement of the tumblers, slides, and lever, and this construction and arrangement make easy the construction and arrangement and the accurate working of the registering mechanism ol'the lock.

The registering arrangement is composed of four levers, Gr, placed side by side and pivoted on the pin m, and they are kept from interfering with each other, their swing or movement is limited by the two sets of plates H and I, within which they-play, and which are secured to the front plateof the lock by the screws n and o. Secured also on screws n and o, and by screwp to the lug q on the inside of the rim of the case of the lock, is a plate, K, provided with a central socket, r, in which a key pivots when turned in the lock;

or when a pipe or barrel key is used a pin Then the, key slips past the end of thelever D, when the action of the spiral spring-B restores the parts will'be substituted for the socket; or the plate I may be altbgether dispensed with and the pin or socket located in the back of the lock.- The rectangular block L, which is firmly w cared to the front plate of the lock-case, is provided with four holes for the reception of the end's of the springs M. that are bent around the stud a, and thence directed between the 7 plates H against the levers G, to assist in op-' ro crating them. To one end of the levers G are attached the parallel segmental tablets N,-on

which are inscribed a cipher and the nine digits, and the other ends of the levers G are broadened into curved ratchets O, in which I 5 engages the spring-pawl P, each ratchet being rovided with as many teeth as there are num-' rs on the corresponding tablets. A sliding or movable plate, Q, provided with an aperture, t, that crosses the tablets N at about a so right angle, covers or nearly covers the tablets, and said slide is operated by the lever R,

that is held on the piuu', and connected with the said plate by means of the pin i, that plays in a slot in the end of the plate. The lever B,for moving the plate Q, is operated through the medium of a master-key, which is used for opening the lock, and which will move the le ver B so as to bring the aperture t in said plate under a corresponding aperture, W, in

the lock, and thus expose to view the numbers or figures registered each time a key has been used for opening or operating the lock,

The lock herein shown will register all numbers from 0001 to 9999, and for each number in this range there is provided a separate key,

whose application to the lock will invariably register a certain combination of numbers and none other, and each key will have stamped upon it the number of the combination it will 0 register, and, in addition, is a 'key called the master-key, that does not change the register. Once applied to the lock and turned so as to pass the lever S, no keysave the master-key can be withdrawn until it has been 5 turned completely around and has moved the tablets to register its number under the aperture in the back plate of the lock, while the master-key alone can move the plate Qtoopen the register, as will be hereinafter explained.

In operating the look, a key is introduced into the key-hole and socket r, pressing down the lever 8 against the pressure of the spring T as it enters, so as to disengage it from the revolving ring U, and at the same time engagbig in the slot a in the edge of the ring. As the ring revolves to the right with the key the spring-lever S bears against the periphery of the ring, so that it is impossible to turn the ring with the key backward to remove the 120?, as the projecting shoulder a of the ring l engage the shoulder a of the sprin -lever 8, thus preventing its being turned" 'arther backward to remove the key. As the ring revalves farther to the right with the ke'y'its eccentric edge b presses against the slide V, and, forcing it against the spring-pawl P,

causes the pawl torelease the ratchet ends 0 of the-levers G. Still turning, the key then strikes one end of the lever W and throws the other end up against the levers G, to bring them all parallel with each other, as shown in Fig. 5. Still turning, the key then releases the lever W, which falls back to its first position, and the key then comes in contact with the'edges of one or more of the levers G, and moves them so that their combined tablets shall register, immediately under the aperture W in the back of the lock, the number correspending with that imprinted on the key, while almost simultaneously therewith the eccentric rim b of the revolving ring U releases the slide V, which permits the spring-pawl P to re-engage with the ratchet or ratchets 0 and hold the levers G, and thereby the tumblers or tablets, in place as registered. At the same time the key is in contact with the slides E and is causing them to operate upon the springtumblers Q to make them release the lever D, by whose means the bolt is drawn back. Then the key comes in contact with lever D and, continuing its movement, forces back the le ver D and bolt until the lock is unlocked, and then, still turning, it releases the lever and permits the bolt to be thrown out again by the action of the spiral spring B and bent springs B. The key being then turned farther around to the key-hole is removed, when the spring-lever S will engage with the lug w of revolving ring U, thus locking it in position. The master-key, when put in the lock and turned, does not carry around with it the revolving ring U, but simply draws back and then releases the-bolt A, until it comes in contact with the lowerarm, d, of the leverR, which it presses down. until the lever draws down the attached slide or plate Q, so that the aperture through it is brought directlyunder the aperture W in the lock-case, thus opening the register, and at this point the said lev'er'R is caught and held by the shonlderf" in the bent spring X. Pressure down upon the stud Z will force the spring down, at any time and release the lever R, when the spring Y, that bears against the arm d,will cause it to force the lever It, with the plate Q, upward, and thus close the register or aperture W.

It will thus be observed that none of the keys exceptthe master-key operates the slide or 'piatetgyddfl'seqnently'tlie "aperture W in lock-case is at all times closed, except when the master-key is used for operating the lock, which will then bring the aperture in said plate Q over the aperture in lock-case, thus per mitting the person having the master-keyto observe the number of the key registered that was last used in opening the lock. Y

The, addition of another lever G and registering-tablet would make one hundred thousand combinations of numbers; but so large a number of keys would hardly one lock. a g I do not confine myself to the precise'form of registering-tablets herein shown,nor to the ITO:

be required for operates both the locking and registering Other modifications'm'a'y be made in applying the device to other styles oflocks without departing from lay-invention.

In the mumor? the key -that part Omslilank nearest the hand operates thering U and the, locking mechanism of the bolt, which may be of any desired construction,-wl1ile the other parts of the key operate the registering mechanism.

Fig. 13 shows a key-blank marked with four rows of nine squares each,to correspond respectively with the number of levers and th numbers on the tablets.

The blank, it will be seen, can be cut away to make the key avoid one or the other or all of the levers, or points may be left to press upon one or all of the levers, and of such length as to press them, or any of them, to the full or partial extent of their range.

The master-key, Fig. 9, is cut away so that it avoids the registering apparatus. The key in Fig. 10 is so cut that only one lever will be moved, and that so slightly as to register only 1. Figs. 11 and 12 show keys that are cut teregisterNos. 1879 and mitrespectiveIyt Having thus fully described my invention, what l claim as" new, Letters Patent, is-
