Original No. 806,166, dated December 5, 1905, Serial No. 235,768. Application for reissue filed. December 4,

To all 'whom it may concern:

Be it known that I, PAUL MoosMANN, a citizen oit the Empire ot Germany, residing in N ew `York, borough of Brooklyn, in the State of New York, have invented certain new and useful Improvements in latchniens Time-Detectors, of which the following is a specification.

The objections to the well-known watchinens tiine-c'tetectors in which a clock-driven dial is used consist in the fact that in place ot' the keys for marking the dial, which keys are suspeiniled at the dilierent stations which the watchman has to visit on his regular rounds, imitation tools or simulating keys can be used for marking' the dial, whereby the real object ot the time-detectors is foiled and the regular and reliable supervision ot the factory or other building rendered n ugatory.

The object o1 this invention is to furnish an improved watchmans time-detector in which, in connection with suitable keys suspended at the ditlierent stations, a very reliable control is obtained, inasmuch as the marking of the time-dial cannot be accomplished by other devices, but only by the keys suspended trom the stations to be visited on the regular rounds of the watchman; a further object is to provide marking means and to so arrange them that the use of a spurious or simulating key may be detected by the operation of the marking means; a further object is to provide a guard-device at one side of the spindle having its operative end capable of movement by the keys in respect to the spindle after a partial rotation of a key on the spindle, and a further object is to provide a clock in which an additional key control is provided which can be adjusted so as to operate the key-controllers or dispense with the operation oil the same or produce an intermittent control of the same which is brought about by a movable key spindle for the engagement and non-engagement of the keys, not capable ot movement by the keys at any point ot the movement ot the keys; and the invention consists oi a f'atchmans time detector having a dial und keys, i:,irotecting means preventing access to the dial until removed b y the key preparatory to the mark- Serial Nc. 405,136.

ing or' the dial, and consists further of a marking means separate from the usual marking means adapted to mark the dial on the operation of any but the true key; and the invention consists further ot" a guarddevice arranged at one side of the spindle having its operative end capable of movement by the keys in relation to the spindle after a partial. rotation of a key on the spindle; and the invention consists further of a watchmans time detector having a movable spindle, but not capable of movement by the keys at any point of the movement of the keys, and a watchmans time-detector embodying the novel features and combinations oi" parts, which will be fully described hereinafter, and iinally pointed out in the claims.

In the accompanying drawings, Figure l represents a lplan view of my improved watchmans time-detector, showing the hinged cover of the same in open position, so as to show the marking mechanism applied to the same, the operating-key being shown in horizontal section. Fig. 2 is a similar top view the open cover of the watchmans tin'ie-detector, showing the key inserted in the same and the marking-plate placed in the proper positionior producing the marking corresponding to the key inserted. Fig. 3 is a vertical transverse section on line 3-3, Fig. l. Fig. et is a detail vertical transverse section on line i-t, Fig. 2.. Figs. 5, G, and 7 are different plan views of the cover and the marking mechanism on the same, showing it in different positions, so as to produce the different functions of the parts. Figs. 8 and 9 are top views of the cover in open position, showing an auxiliary guard device for preventing tampering with the marking device by imitation keys in normal position and when actuated by the ward of a key; and Figs. l0 and 11 are vertical transverse sections, respectively, on lines 10-10, Fig. 8, and ll-ll, Fig. 9.

Similar letters of reference indicate corresponding parts. f

Referring to the drawings,4 A represents the body oit a watchmans time-detector of the well known type in which a graduated paper dial vD is rotated 'by a clock-train mechanism located in the body A and marked from time to time by means of keys that are suspended from the different stations in the factory or other building. The paper dial D is applied to the movable top plate of the clock-train by the usual devices and the clock-train wound up before l the clock or detector is handed to the watchman, a new time-disk being inserted from day to day in the usual manner.

The cover C is hinged to the main part or" the time-detector and locked thereto in a suitable manner, the cover being shown in the different figures of the drawings, with the eX- ception of Fig. 3, as being in an open position for the better description of the different operative parts arranged on the same. In Fig. 3 the cover is shown in closed position, while the main portion or body A is shown in dotted lines above the same. On the inner surface of the cover C is arranged a shiftable spindle E, which is guided at one end in a socket a, that is attachedto the cover at a point opposite to the key-opening a2 for the marking-keys. On the spindle E is guided a. bracket e of a slide-plate E', which is guided in ways of a keeper e2, attached to the under side of the cover C by suitable fastening-screws, as shown in Figs. l, 3, and 4. To the opposite end of the side-plate E is riveted or otherwise attached a springplate E2, which extends longitudinally over the slide-plate parallel with the spindle E, said spring-plate E2 carrying at its opposite end a steel marker e, which is located adjacent to and sidewise of the tapering end of the spindle E. To the opposite shouldered end of the spindle E is applied the perforated bracket f of a second slide-plate F, which is guided adjacent to the bracket f along a grooved stud located at the rim of the cover C,'and at'its opposite end by a slot f2 on a headed pin f3 on the cover G. Between the bracket e on the slide-plate E and the bracket f on the slide-plate F is interposed on the spindle E a helical spring f4 which acts on both brackets and serves when set to tension by either one to return it, with its slide-plate, into its former or normal position. The slide-plate E is moved inwardly against the tension of the spring f4 when one of the keys at the different stations is inserted through the key-opening of the cover C and returned by the spring f2 as soon as the key is withdrawn. The barrel of the key K is provided with a laterally-extending ward w, as shown clearly in Fig. 4, so as to permit the entry of the key-barrel and its ward into the correspondinglyshaped key-opening of the cover, which opening is surrounded by a bushing or keyboX a2, provided at its inner end with a recess a in line with the spindle E. The

length of the key-barrel and its ward ldetermines the inward motion of the slide-plate E and marker-plate E2, each key havl ing a barrel and ward ot a predetermined length, which differs from the key-barrels and wards of the remaining keys,'so that the indicating-mark made by the use of each key may be identified by position on the dial. The bracket e is provided in its upper part with an arc-shaped sloteA2 for guiding the projecting shouldered end g of a guardspring g', the opposite end of which is attached to the edge of the spring-plate E2, as shown clearly in Figs. 1 and 2, said projecting end g forming a guard-pin that prevents the ward of the key K to be turned in one direction-that is to say, toward the left-and necessitates thereby the turning of the key in the opposite direction-that is to say, toward the right-so that the ward w engages the raised end of the marker carrying spring-plate, depresses the same, and permits after clearing theI same the release of the spring-plate, as indicated in Fig. 4, so that the marker is quickly moved by the action of its spring-plate back into its normal position and produces thereby by its sharp-pointed end the marking of the time-dial of the clock-train.

One part of my invention consists in providing a guard-device at one side of the spindle having its operative end capable of movement by the keys in respect to the spindle after a partial rotation of a key on the spindle.

The projecting end or guard-pin g of the guard-sjning g is normally located atthe left-hand end of the slot e* and serves thereby as a guard for the proper turning of the key. Wlhen the key is turned on its axis for actuating the marker, the ward enthe projecting guard-pin, carries the same along until the key and its ward are again brought in line with the opening in the key-box, as shown in Fig. 4, in which position the projecting guard-pin arrests the ward and prevents a second turning motion ot the key and the second actuation of the marker. As soon as the key is again in line with its key-opening the tension of the helical spring f4 on the bracket e of the slide-plate E moves the key in outward direction, the parts returning from the position shown in Fig. 2 to their initial or normal position. (Shown in Fig. l).

Another part of my invention consists in providing a movable key spindle for the engagement and non-engagement of the keys, not capable of movement by the keys, at any point of the movement of the keys.

The end of the spindle E is made tapering, the tapering end being adapted to engage the correspondingly-recessed end of a spring-cushicned. spindle 7L of a worin-shaft L, that turns in suitable bearings in the casing ot the key K, so that by the turning ot the key in operating the marking device of the time-detector this spindle is held stationary by the spindle E, and thereby turned relatively to the key-casing, whereby motion is transmitted to a worm connected therewith and thence to a suitable worm-gear h3, by which the key-controlling mechanism Il, located in the casing ot the key, is operated, a record being made of each actuation of the. marking device of the time-detector by the controlling mechanism of the key K.

The improved construction of the key and the key-controlling device and the casing of the same forms the subject-matter ol a separate application for Letters Patent liled upon the date of the original application.

Sidewise oit' the inner end of the key-box, near the rim of the cover C, is arranged a stationary stop-hook te, having an inclined face, so that when the ward 'w of the key K is inserted into the cover and turned so as to depress the spring' marking-plate E2 the ward passes below the hook and is prevented from turning back toward the left, as shown in dotted lines in Fig. et, but has to be moved onward toward the right until it clears the spring-plate E2 and produces the marking oit` the dial, while the end of the key engages the bracket e and moves the slide-plate E in backward direction against the tension of its helical spring y, as described. The ward te of the key K, not being able to be returned toward the left owing to its engagement by the stop-hook fw, has to be turned toward the right until the key has completed its rotation and is moved by the action of the helical spring f* in outward direction in the key-box, the edge ot the ward moving along the inclined face of the recess a in the key-box a2 until the ward is in line with the keyhole, when the spring-actuated bracket e" will move the key in outward direction for its final withdrawal by the watchman.

To the slide-plate VF is pivoted a lever I, to the pivot of which is applied a torsionspring e', which tends to move the lever I toward and along' an antiriction-roller v1, that is applied to a stationary pin on the cover C. To the pivot of the lever I is attached below the lever, but above the slideplate F, a second lever-arm I, which moves with the lever I and is provided with two recesses 2 27"" on the side facing the antifriction-roller, one for engaging a stationary pin t and the other for engaging the anti- Jfriction-roller if', as shown in Figs. l and 7. Then the lower lever-arm I is not locked to the pin l" or to the roller it is moved Jr'reely with the slide-plate F forward and backward toward the lett, as shown in F and 5, so that the end of the spindle E is withdrawn into its guide-socket a. The tapering end of the spindle E is thereby prevented :from engaging with the spindle at the interior of the key-barrel, and consequently unable to actuate the supplemental controlling device ot' t-he key, as shown clearly in Fig. 6, for the reason thatl the spindle does not project far enough into the barrel of the key for engaging the end of the spindle of the controlling mechanism.

The improved key-controlling device can be automatically thrown out of action, when it is desired to do so, after a certain predetermined period of time. For this purpose the lower lever I is placed with its recess 2 against the roller 71, as shown in Fig. 7, so that the upper lever I extends inwardly over the spindle E and into the path of a pin 79, projecting from the top plate of the clock-train and passing through the timedial, as shown in Fig. l. This pin moves with the time-dial and engages at the proper time the end of the lever I and moves the same suliiciently so that the recessed lowerlever arm I clears the roller i and permits the return movement of the spindle E under the intluence of its heli/cal spring into its socket a. and the motion of the slide-plate F into the position shown in Fig. 5, while the levers I, I are moved by the torsionspring t' into the position shown in Figs. 5 and 6. In this position the spindle E is withdrawn, and will consequently not act on the controlling devices in the key until reset again. By the three positions ot' the lever mechanism described the spindle E may be placed in position so as to actuate the controlling devices in the keys, or the spindle E may be. moved out of action, so as not to acuate the key-controlling devices, or it may be placed in such position as to be automatically released after a certain period of time. Vhen it is desired to lock the slideplate F permanently, so as to set the spindlesupporting bracket 7 and the spindle E in or out of operation, a pivoted stop-piece r, capable of moving in one or the opposite direction, is placed into engagement with one or .the other side recess 1 or r2 in the slide-plate F, as shown in dotted lines in Figs. l and G. The slide-plate F is thereby held in one case permanently in position for vthe actuation of the key-controlling devices,

while in the other case it is held in position with the spindle E permanently out of engagement with the key-controlling devices.

On the face of the disk operated by the clock-train are arranged two pins 79 and 7] intended to pierce the dials and hold them in position on the disk. A further pin 723 is arranged, which is adapted to engage with the leve-r I at a certain time so as to actuate the lever. A. fourth pin 722 is arranged at a distance of about 900 from the pin 773, and this pin determines the time when the lever I is to be actuated. As is well known and as is usual, the dials are provided with number-divisions corresponding to the hours.

If, for instance, it is desired that the lever I is actuated at live olclock, then the dial is so placed on the disk as to have the pin p2 pierce the dial at the five-hour mark, the distance between the pin p2 and the pin p3 being of such length that when the fivehour mark of the dial, or rather the pin 292, arrives at the marking point, the pin ya* will arrive in a position to actuate the lever' I. Hence by this arrangement the time when the lever is to be actuated is fixed.

Another part of my invention consists in providing protecting means preventing the marking` of the dial, until removed preparatory to the marking of the dial by the key intended to make a marking.

In Figs. 8 to 11 is shown an additional guard device which in the embodiment shown in these figures is to be used in connection with the spring-actuated bracket e on the spindle E, said guard device being intende-d to prevent the marking of the timedisk by the marking-point in case a spurious or imitation key is used. This guard device consists of an angular guard-plate u, which is attached to the free end of a curved spring u, the opposite end of which isattached to the end of the guideway e2 of the spring-plate E2 carrying the marking-point e, said guardplate extending around the marking-point, as shown in Fig. S. The rear portion of the angular guard-plate u is provided at its upper edge with a horizontal flange u2, that projects over the spring-plate E2, as shown in Figs. S and 10, while the face of the side portion of the guard-plate a is obtusely recessed adjacent to the spindle E, said face being sufiiciently close to the spindle to be in the path of the ward of the key when the same is inserted and turned in the key-box, as shown in dotted lines in Fig. 10. Then the key is inserted in the tin'ie-detector, it forces the bracket e backward against its tension-spring ft, as shown in Fig. 9, its ward on the turning of the key catching beneath the raised upper portion a3 of the bracket e, so as to be locked against return movement. Upon the further forward movement of the key the ward thereof in engaging the obtusely-angular recess in the guardplate u forces the same away from the spindie, and with it the flange u2, so that the latter uncovers the marker-plate, which is simultaneously depressed by the ward of the key, as shown in Fig. ll. The guardplate u is moved back sufficiently that its flange u2 clears the marking-point e, as shown in Fig. 1l, and permits thereby on the release of the spring-plate the actuation of the same and the marking of the timedisk on the clock-train by the markingpoint. The raise ya3 on the bracket e prevents the key from being turned in opposite direction when once properly inserted, and forms thereby in the same manner" as the stop to a means for preventing the turning of the key in the opposite dir-ection. Ibenever an imitation key, which is usually provided with a short ward, is inserted and pushed inwardly, so as to force the springactuated bracket e in backward direction, the ward will engage the spring-plate of the marking-point in the same manner as the genuine keys at the different stations, but it will not engage the spring-actuated guard-plate u and push its flange clear of the marking-point, so that when the springplate is actuated it is held back by the guard-flange u? and prevented from being raised sufficiently so that the marking-point cannot mark the time-disk. i

Another part of my invention consists. in providing marking means so arranged whereby the use of a spurious or simulating key may be detected.

The momentum of the spring-plate causes the latter to produce the. lifting of the flange u2 of the guard-plate u, so that a point at, located at the upper edge of the rear portion of the same, produces a slight pricking mark on the circumference of the time-disk, indicating thereby on the inspection of the time-disk that an attempt has een made to tamper with the marking of the time-detector by an imitation key. The angular spring-actuated guard-plate forms thus a device for preventing the marking of the time-disk by the marking-point when an attempt is made to operate the time-detector by an imitation key and also indicates that an attempt was made of tampering with the time-detector by the pricking mark caused by the point at on the guard-plate on the time-disk by the momentum imparted by the guard-plate 'a by the spring-plate E2.

By the improvements described watchmens time-detectors of the class referred to are rendered more accurate and reliable, mainly for the reason that the tampering with the detector by spurious or imitation keys is absolutely prevented, as the key when once inserted into the cover of the timedetector is fully controlled throughout its motion in the same and ejected from the .time-detector when the full rotation required for the actuation of the markingpoint is completed. The different guard and safety devices described overcome thereby some of the well-founded objections to this class of time-detectors, render them more reliable, and permit them to be adjusted so as to operate the auxiliary key-controllers or discontinue the operation of the same or operate the same for a predetermined period of time and discontinue them automatically by the action of the clock-train at the will of the owner of the buildings to be watched.

Certain novel features have been described in the foregoing specification, these novel features being shown as one embodiment of my invention. These features, may, however, be used With and applied to Watchmans clocks other than the 'type shown. Fundamentally, as stated, these novel features consist ot': l. The movable key spindle .tor the engagement and non-engagement oi? the keys, not capable of movement by the keys, at any point of the movement or' the kevs. 2. The marking means separate from the nsual marking means adapted to mark the dia] on the operation of any but the true key. 23. The guard device arranged at one side of the spindle, having its operative end capable of movement by the keys in respect to the spindle at'ter a partial rotation ot' a key on the spindle. 4. The protecting means normally preventing the marking of the dial until removed preparatory to the marking ot' the dial by the key intended to make the marking. I have shown a praetical embodiment of these fundamental features, and since it is very evident that such embodiment might be varied Without departing trom the spirit of my invention, I do not Wish to limit myself to such detailed characteristics necessary for a full disclosure and understanding of my invention.
