WATCHMANS TIME-DETECTOR.

EZ-EGIFICATION forming part of Letters Patent No. 510,745, dated December 12, 1893.

Application filed December 20, 1892. fi erial No. 455,765. (No modelfi' T aZZ whom it 71mg concern:

Be it known that I, CHARLES \VEINEDEL, a resident of Louisville, in the county of Jetfer son and State of Kentucky, have invented certain newand useful Improvements in W'atchmens 'limeDetectors; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- IO pertains to make and use the same.

My invention relates to an improvement in watchmans time detectors,the object being to construct the device in such manner that it shall be adapted to be operated by the i5 watchman at certain predetermined intervals of time and so that it cannot be operated until it given interval of time shall have expired.

A further object is to construct a watchmans time detector in such a manner that the instrument itself will indicate whether or not it has been properly operated and so that at each operation of the instrument the number of the instrument will be recorded at a central oftice.

A further object is to construct the device in such manner that it cannot be tampered with by the watchman.

Vith these objects in view the invention consists in certain novel features of construc- 0 tion and combinations and arrangements of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings: Figure 1 is a face view of the device. Fig. 2 is a face view with the casing removed. Fig. 3 is a View illustrating the means for stopping the clock movement, and showing the parts in position to operate the signaling devices. Fig.4 is a separate viewillustrating the clock starting mechanism. Figs. 5,6,7, 8 and Qare detail views. Fig. 10 is a view in side elevation, the casing being shown in section.

A represents a back or base plate to which the mechanism hereinafter described is attached, said mechanism being inclosed by a casing 13 fixed to the back orbase plateA and having a glass front 0 through which the indicators can be read. This case is permanently secured to the back or base plate A and is not to be removed by the watchman who operates the device, thus preventing the watchman from tampering with the device and sending in false signals. A clock movement D is secured to the back plateAand in its structure comprises a wheel or pinion a. adapted to make one revolution in one hour.

It also comprises a wheel or pinion b adapted to make one revolution in, preferably, twentyfour hours.

Mounted looselyon the shaft a of the wheel or pinion a and adapted to be carried by and rotated with the wheel b,is a disk c,havinga single tooth c. A notched disk (Z- is revolubly mounted below the disk 0 and has produced in its face a series of numbers from 1 to 7 inclusive, said numbers representing the days of the week. The tooth c is adapted to mesh with the notched disk (1 at each revolution of the disk 0, and said disk making one revolution in twenty-four hours it will be seen that the numbered disk (1 will be moved one notch every twenty-four hours.

Secured to the arbor e of the spring 8, is a collar (2 from which an L-shaped arm a projects, the free or bent end of said arm being adapted to engage pins e projecting from the wheel or pinion a, the clock mechanism being so time that one of the pins e will reach a point over the shaft of the pinion a at the same time that the free end of the arm 6 reaches the same point and thus stop the clock movement. The pins e will preferably be arranged at diametrically opposite points on said wheel so that the wheel, and consequently the whole clock movement, will be stopped once every half hour. It is evident however, that only one pin a may be employed so as to cause a stoppage of the movement once every hour,or more than two pins may be employed so as to cause the 0 movement to stop oftener than once every half hour. An arm f is secured to and projects laterally and normally slightly upwardly from the arbor e. To the outer end of the arm f, a pitman f is pivotally connected, 5 which pitman extends downwardly and at its lower end is pivoted eccentric-ally to a disk g, which latter is loosely mounted on an arbor g supported by a frame g A sleeve g projects from the center of the disk g and is too adapted to receive the end of said arbor g' the free end of said sleeve being preferably closed and adapted to receive a crank arm It, said crank arm being secured to said sleeve by means of a pin it. From this construction it will be seen that when the disk g is partially rotated the spring 6' will be partially wound, through the medium of the arm f and pitman f, and the L-shaped arm a will be carried away from the pins e carried by the wheel or pinion a. When the disk 9 is thus partially rotated the L shaped arm e will be carried from the pins of the wheel a far enough so that the running of the clock movement for a half hour will bring it back again in alignment with the pins 6 so that its engagement with one of them will cause the clock mechanism to stop. From this it will be seen that it is necessary for the watchman to operate the device once every half hour.

A collar 1' is carried by the disk 0 and adapted to embrace this collar is a hand or pointer i, which registers with figures on a dial 2' The figures on the dial will preferably range from one to twenty four, thus representing twenty-four half hours,or, when the device is adapted to be operated once every hour, the figures will represent twenty-four hours.

A spring j is connected at one end to the shaft or arbor g and at the other end to a pinj' projecting from the frame 9 A gear wheel is is loosely mounted on the shaft or arbor g and carries a pivoted dog adapted to engage a ratchet wheel k secured to the shaft or arbor g, a spring 10 secured to the wheel 7 being employed to retain the dog in engagement with said ratchet wheel. The gear wheel 70 is adapted to mesh with a pinion Z carried by an arbor Z. The arbor Z also carries a spur wheel 1 which meshes with a pinion Z carried by an arborl. The arbor Z also carries an escapement wheel Z with which an escapement pawl l engages, said escapement pawl having a weighted arm Z secured thereto to insure its proper operation. A disk in is secured to the arbor Z and is provided-on its periphery with teeth or projections m. An insulating block m is secured to the frame g and to this insulating block a spring a is secured and adapted to be engaged by the teeth or projections m on the disk m. The disk m and spring n are included in an electric circuit indicated by the wires 0, 0', said electric circuit extending to a central station where it includes an instrument of suitable construction. From this construction it will be seen that when the-disk m is permitted to rotate by the operation of the device the proj ections-m' will successively engage the springn and thus make and break the electric circuit, and thus cause the instrument at the central office to report the number of the box operated.

A lever 19 is pivotally connected to the under side of the disk g, and is provided with an arm 0' which, when the parts are in position to be operated, engages a spring 19 secured to the frame 9 The lever 19 is guided in its movements by means of a pin 9 pro-' jecting through an elongated slot p in the disk g. On the inner face of the lever 19 a shoulder q is formed, with which an arm q projecting from a collar (1 fixed on the shaft or arbor g is adapted to engage when the parts are in position to be operated. An arm 4" projects from the collar (1 and is preferably made in the form of a segment. At one end of the segmental portion of the arm r is a projection r, with which a pin r on the make and break disk engages to limit the movement of said disk. In order to relieve the strain on the pin r byits constant and sudden engagement with the arm 'I', a spring or yielding device s is secured to the frame g and adapted to receive the end of the projection r of the arm r, said projection reaching the spring 5 slightly in advance of the pin r on the make and break disk. I

Now let it be supposed that the clock movement has been brought to a standstill and the operator wishes to manipulate the device. He grasps the crank arm h and causes a partial revolution of the disk g. By this movement of the disk the spring of the clock movement will be partially wound up and the arbore to which said spring is attached will be rotated thus raising the arm a out of engagement with pin 6 and thereby release the clock work. When the disk 9 is in position to be operated (and before it is rotated as above mentioned) the spring 19 is in engagement with the arm p of the lever pand retains the shoulder q in engagement with the arm q projecting from the collar g Now, suppose the disk to be partially rotated as above described. It will be seen that the clock movement will be set free asabove mentioned and that the shaft or arbor g will be rotated and the spring j wound up. When the disk shall have been rotated sufficiently the end of the lever 19 will engage a stop If supported by the frame g and thus be moved away from the arm q,thereby releasing the spring j and the parts which it actuates. Thus it will be seen that the make and break mechanism will be set in motion and the signal turned in. The clock movement will now continue its operation and as'it operates the disk d will be moved slowly to the starting point, at which time the clock movement will be again stopped.

A sliding bar to is connected to oneside of the frame of the clock-movement and, provided with elongated slots u, for the passage of the pins or screws which support it. An arm 20 projects downwardly from the sliding bar u and at its lower end is bent so as to lie normally, in the path of a pin a projecting from the under face of the disk d. In proximity to the upper end of the sliding plate u,

when the device is operated to set the make and break mechanism in motion, the pin a projecting from the disk will strike the arm a of the sliding plate u and thus start the clock movement.

In operating the device, the watchman will grasp the crank arm h and cause a partial revolution of the disk J. The disk g being connected with the winding arbor of the clock movement, by the pitmanfand arm f, when the disk g is turned as above explained, the winding arbor will also be turned and thus the spring of the clock movement will be wound. When the winding arbor is thus turned, the end of the L-shaped arm a will be moved up, outof engagement with the pin c projecting from the wheel or pinion (I, thus releasing the clock movement. When the disk is turned by the watchman as above explained, the pin a on the disk g will strike the arm 102 projecting from the bar it and cause an upward movement of the latter. Then the bar to moves up, the spring arm 21; carried thereby, will strike the escapement lever a and set the clock movement in motion. The clock movement will run for one-half hour, when it will be stopped by the engagement of the L-shaped arm c with one of the pins c on the pinion a. During the operation of the clock movement,thepointer-i will move from one figure on the dial 2' to another, the figures on said disk counting, as above stated, by half-hours. At each revolution of the disk 0 on the shaft a, the tooth c on said disk will engage one of the notches in the disk cl and cause a movement thereof,the figures on said disk indicating the days of the week, as above described.

\Vhen the disk g is turned to produce the operation of the clock movement above mentioned, other devices will be set in motion, whereby to operate electrical signaling mechanism, the operation of which mechanism is as follows: When the disk g is turned by the watchman, the arm g carried by the shaft or arbor g will engage the shoulder g on the lever 19 and thus cause said arbor to move with the disk g and wind the spring j, the shoulder q of said lever 12 being retained normally in engagement with the arm g by means of the spring 13 When the disk g and its arbor g shall have been moved to a suflicient extent, the forward end of the lever 19 will engage the pin or stop tand byit will be moved out of engagement with the arm q, thus releasing the arbor g from the disk g, whereupon said arbor will be rotated by the spring j and cause the operation of the electrical make-and-break mechanism, in a manner which will be presently explained. The disk g will be returned to its normal position by means of the clock movement, through the medium of its connection therewith and when it reaches its normal position (which requires a half hour), the shoulder on the leverp will again engage the arm q. Thus it will be seen that the device cannot be operated oftener than each half hour. In other words the watchman cannot turn in the signal before the prescribed half hour has expired. When the arbor g and the disk propelled thereby have been rotated sufficiently by the spring they will be stopped by the engagement of the segmental arm r with the pin T In order to prevent the breakage of the pin 1' by the sudden or abrupt engagement of the segment 0', the spring arm or yielding device 5 is employed.

\Vhen the shaft g is rotated by the spring j as above explained, motion will be imparted,

through the gearing above described, to the make-and-break disk m, causing its teeth or projections m to ride over the spring p and thus make and break the electrical circuit which includes said disk and spring-thereby operating the signaling amiaratuslocated at a central station.

From the construction and arrangement of parts as above described it will be seen that it will be impossible for a watchman to operate the device until a certain predetermined time has expired. The hand or pointer will indicate the number of signals turned in, which will prevent watchmen and operators at the central station from working together and giving false reports. The reportcoming in from the central office must tally with the indicator on thetime movement. By this means a report is had from the clock movement and also from the central ofiice, thereby watching both watchman and operator at the central station. In a building where a number of time detectors are employed, it is not necessary to provide more than one with the make and break mechanism, as all the indicators must tally with the one having the make and break mechanism.
