To all whom it may concern:

Be it known that I, ALBERT- C. FRIESEKE, a

V citizen of the United States, residing at J ack sonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in XVatchmans Electric Time- Recorder; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to watehmens tiniedetectors of that class in which a clock-movementor suitable train of gearing is employed to regulate the feed of a narrow strip of paper beneath a stylus which, when actuated, prints a character or punctures the strip, there by registering the time at which the stylus was actuated.

Heretofore, when the watchman had to press a button at each station or room under his surveillance, so as to register the time at which he visited such station, a separate line, magnet, and stylushad tobeprovided for eachline; and, again, that the watchman may not remain ata certain station and register from any one fixed point without the same being madeknown, the magnets are arranged in such reltive positions and the armatures carrying the points are so constructed that the points are-in a line at right angles to the path of the strip, and each point occupies a diiferent position relative to the width of the strip. Thus, if the registering is done from any one point, the imprint of the point or stylus corresponding to such point will be in a line parallel with the edge of the strip, whereas, if the watchman observes his duty the imprints will occupy different positions on the strip. It has been proposed to use but a single magnet to do the registering, in which case a clock-movement is placed at each station and so arranged as to close the circuit at that point by the simple winding of such movement when the same has run down suiiieiently to permit the winding. This arrangement has been found ebjcctionable and faulty, as the registering may be donefrom any desired station by the winding of the movement at fixed intervals when the same has run down sulliciently to permit but a three-fourths turn of the springbarrel arbor. My invention is designed to overcome these objections and make it obligatory that the watchman should go his rounds, and that the stations thereof be visited in sue cession. Otherwise no registry will be made, as the line-circuit when closed at one point is shifted and can only be closed again at the next consecutive point,and so on. By my system and arrangement the number of parts are reduced to a minimum, thereby simplifying such systems, and the operation of the various elements are positive, thereby rendering the system more efficient.

In carrying out my invention the elements employed are a clock-movement, a paper fillet regulated in its travel thereby, an electromagnet, the armature of which is provided with a stylus to imprint upon the fillet, and a circuitchanger, which forms the terminal of the lines from the various stations or points from which the registering is to be done.

My invention consists in combining with a paper lillct a clock-movement to regulate its feed, an elcctro-niagnct to actuate an armature carrying a stylus, and a circuitchanger.

It also consists in coinbi ning with such movement an arm which forms one terminal of all the stations, and which is carried thereby over a series of contacts forming the other terminal, thereby establishing and breaking the line-eircuit from each point in succession.

It further consists in the circuit-changer and electro-magnet with means whereby the circuit-changer is positively operated upon by actuating the armatureoi' the electro-magnet, which armature at the same time may or may not close a local circuit to the register at a distant point, as desired.

Q It also further consists in combining with the fillet a continuous positive feed, which is held in check and the feed of the fillet regulated by the aforesaid Cl0Cll]lOV6l116Db. To render more positive the action of the clockmovement on the fillet-,t-he latter is perforated throughout its length at stated intervals, and such perforations are engaged by the teeth of a sprocket-wheel having its motion governed by the clockanovement.

In addition, the invention consists in the novel details of construction and combination of parts, as more fully shown and hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view of my improved register. Fig. 2 is a side elevation of the upper portion thereof, partly in section. Fig. 3is a view of the circuit-changer and its support as it appears when viewed in the direction of the arrow, Fig. 2. Fig. 4 is a view similar to Fig. 2, of a modified form. Fig.5 is a section on the line X X of Fig. el,l0okingin the direction of the arrow. Fig. 6 is a section on the line Y Y of Fig. 4, looking in the direction of the arrow. Figs. 7 and 8 are diagrammatic views.

The base A supports all the operating parts of the register, which consist of the clock-movementB, frame 0, which supports the fillet-reels and the fillet-regulating devices, circuit-changer D, and registering-magnet E. The opposite ends of the frame Care provided with upwardly-inclined slots c,for the reception of the journals of the fillet-carrying reels a. A shaft, F, suitably journaled in the sidesof the frame C, has connectionswith andis driven by theclockmovement, preferably by means of a pinion, F, secured on or near the end of the shaft. A fillet, G, passes over this shaft, and has its movement regulated thereby, which may be done in numerous ways, either by affixing a roller, H, to the shaft, having an elastic surface, and having a second roller, H, mounted in a yielding or spring support, H pressing against and actingin conjunction with theroller H,to keep the fillet in close contact with the roller H, between which and the roller H it passes. A second method of feeding the fillet is to have it pass over a bed, 1), beyond the surface of which the teeth of a sprocket-wheel, I, extendto engage theperforations g in the fillet, which perforations may be made to correspond with the short cross-lines g. These cross-lines and perforations indicate intervals of time of any duration. For convenience they are shown as representing intervals of five minutes, or twelve divisions to an hours time. The sprocket-wheel has twelve teeth, and is so moved that it makes a complete revolution in sixty minutes, during which time the fillet has moved forward twelve divisions, which represent one hours time, and is so marked on the fillet to facilitate the reading. It will be understood that these two devices may feed the paper forward but it is found preferable to have the fillet fed forward in a positive manner and use the cloclcmovement as a retarder or regulator. For this purpose the movement shown at J is employed. Where the fillet is positively fed, as just described, it is liable to slip between the rollers, asHH. Consequently the sprocket-wheel is deemed best, either with or without the fillet being perforated, although the perforations are best. Keepers bare employed to hold the fillet to the bed. The armature K of the registering-magnet E is provided with a point or stylus, K, which impresses the paper when the magnet is energized, to indicate the time at which such impress was made. Vhen the roller H is employed, its elastic surface forms the bed and permits the indentation of the fillet, as will be readily understood; but when a bed, as b, is employed the same is perforated, as at b*, in register with the stylus. A carbon-strip or inked ribbon may be advantageously used, if desired, and can be readily attached; but as this forms no essential feature or part of the invention the application of the same is not shown.

For convenience of illustration, the magnet is shown opposite the clock-movement, and its armature is hinged at one end to the frame 0 at k, and extends over the shaft F. A retracting-spring, L, holds the armature at a distance from its magnet, the distance being regulated by a set-screw, m, passing through an arm, m, of the overhanging standard M, from which the spring L depends.

The circuit-changer is composed-of a disk, N, of rubber, wood, or any suitable insulating material, a number of contacts, a, arranged around the periphery, but electrically insulated from each other, and a moving contact, 0, carried by a crank-arm, O, keyed to or mounted on a shaft in axial line with the center of the disk N. This shaft maybe either the shaft F, with which it moves, or the shaft P, which consists of a screw passed through the disk and a ratchet-disk p, mounted thereon, to which the arm 0 is affixed. In the first instance the arm 0 and its contact 0 is moved in unison with the feed-regulating devices and is independent of the movement of the armature of the magnet. In the second device the contact 0 is moved at each movement of the armature, and is therefore preferred, as the circuit-changer may be located at a distance from the register, thus saving the cost of having a multiplicity of wires running direct to the register. The circuit-changer in this instance is provided with an electromagnet independent of the registering-magnet, and is usedto close a local circuit to the register, as more fully hereinafter set forth.

Projecting from the armature K is a springpawl, Q, which engages a tooth of the ratchetdisk 19, and moves the same forward at each movement of the armature. This movement preferably takes place at each retraction of the armature. This form of circuit-changer may be used in connection with the register, as clearly indicated in Fig. 4.

To effect an electrical connection between the shaft F and a terminal of the registeringmagnet, the shaft is extended and journaled in a bracket or support, R, which is in electrical connection with such terminal.

To insurea positive and continuous connection, a spring, 1-, is secured to the standard and its upper end arranged to bear on the end of the shaft.

Referring to the diagrams 7 and 8, the num-- erals 1 2 3, 820., represent the linecircuits from corresponding stations, 1 2 8, &c., each ICO IIO

line terminating with one of the fixed contacts a on the disk N. Each station is provided with a circuit-closing key, U.

Having reference to Fig. 7, V represents an electric battery; c, a wire connecting with a terminal of the registering electro magnet, and S the other terminal or pole of the battery, connecting with the various stations 1 2 3, &c.

The operation is as follows: The arm or contact o is shown as resting upon and electrically connected with the terminal of the linewire from station or point 5. The circuit being closed at this station the current will be from the batter through wire 12, to magnet, to standart It by wire 0, through shaft F to arm 0, from arm 0 to line-wire 5, through contacts 0 a, thence to battery through wire S. The current in its passage will energize the magnet and cause it to attract the armature, the stylus of which will impress the fillet at one side of the perforations or divisionanarks, thus indicating the time at which the circuit was closed at station 5. It is evident that a current cannot be sent from any other station by reason of the interruption of the lines at the eircuitchanger. From the foregoing it will be understood that the arm or contact 0 moves from one contact, n, to the other in succession, thus successively opening one circuit or line and closing the next; hence, it is apparent that the registering can only be done from the proper point and from each in succession. This construction is best adapted for short circuits, where the stations are eomparatively near the register; but where it is designed to use a second, but single register, and to locate it at a distant point from the stations under surveillance, the construction shown in Fig. 8 is resorted to. In this latter case I use two registers or a register and circuit-changer simply, the former being constructed as deseribed,with this exception, that the circuit-changer is dispensed with, the registering-inagnet being included in a local circuit, which is closed by the circuit-changer magnet. The local battery V has one pole connecting with the registering-magnet by wire r. The other pole is grounded by wire S. A line, w, connects the register with a point, tr. An arm, VJ, carried by the armature of the circuit-changer magnet, serves to close the local circuit through the ground-wire 20 when said armature is actuated. This may be done in a number of ways, and I do not restrict myself to the manner shown, in which said arm W is in electrical connection with the armature and the latter grounded by the wire w.

The operation is as follows: Upon closing the proper circuit through the circuit-changer its armature will be actuated and the local circuit closed by the contacting'cf point w and arm W, as will be readily understood, thereby causing the registering to be done at the distant point.

By reason of the circuit-changer the proper claim, and desire to secure by Letters Patent,

1.
