EEECIFICATION forming part of Letters Patent No. 759,177, dated May 3,1904.

Application filed September 23, 1903. Serial No. 174,271- (No model.)

To all whom it may concern:

Be it known that I, CHARLES T. HAWLEY, a citizen of the United States, and a resident of Gardner, county of Worcester, State of Massachusetts, have invented an Improvement in Watchmens Time-Recorders, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to watchmens timerecorders such as are used to record the time at which a watchman visits certain fixed points or stations in factories, ofiice-buildings, hotels, &c., whereby an accurate record is made and preserved of the manner in which the watchman has performed his duty. The particular type of such recorders to which my invention is specially applicable is that in which the record-sheet is detachably mounted on a revoluble drum or cylinder operated by a suitable clock mechanism, the time of the watchmans visit to a station being recorded upon the sheet by a stylus which makes a puncture therein.

My invention comprises various novel features of construction and arrangement whereby the operation, efficiency, and durability of the apparatus is improved, with a very considerable simplification of construction and convenience of operation. Such novel features will be fully described in the subjoined specification, and particularly pointed out in the following claims.

Figure 1 is a front elevation of a time-recorder embodying one form of my invention shown as mounted in the usual inclosing case, the door of which is thrown open and the revoluble cylinder or drum on which the record-sheet is carried is broken out centrally to show certain portions of the apparatus beneath it. Fig. l is a plan view of one of the supporting-plates for the electromagnets to Fig. 3 is a front elevation of the revoluble cylinder and its supports and also showing the telltale for recording the opening and shutting of the door of the inclosing case, the cylinder being centrally broken out to save space. Fig. 3 is an inner face view of the cylinder-support shown at the right, Fig. 3, and also illustrating the driving or transmitting connection between the cylinder and clock or motor. Fig. 3 is an inner face View of the cylinder-support shown at the left, Fig. 3. Fig. 4 is an enlarged sectional detail on the line 4: 4:, Fig. 3, of the driving or transmitting connection for the cylinder. Fig. 5 is a side elevation of one of the armatures and its connected stylus or perforator to bedescribed. Fig. 6 is an enlarged detail, in side elevation and partly broken out, of the stylus or punch and the means for limiting its perforating movement. Fig. 7 is a transverse section on the line 7 7, Fig. 6, to be referred to. Fig. 8 is a longitudinal sectional detail, enlarged, of a portion of the armature on the line 8 8, Fig. 5, showing the pivotal connection between the armature and the punch or stylus; and Fig. 9 is a transverse section, enlarged, on the line 9 9, Fig. 5, to be referred to.

The apparatus is mounted in a suitable case A, Figs. 1 and 2, and herein shown as provided with a swing-door A which is intended to be opened only by such person as may be authorized to remove and replace recordsheets, and I have provided a telltale device which automatically registers each opening and shutting of the door, so that any meddling therewith is recorded in an inefiaceable manner. This telltale device will be described hereinafter.

The case is provided with a clock O of any desired construction and operatively connected with and rotating the record-cylinder, as will be described.

The working parts of the recording apparatus are mounted on a rigid base B, preferably a grid-like casting, having legs Z) 6 to rest against the back A of the case and attached thereto by suitable screws 2, Fig. 1,

the upper legs 6 being shorter, so that the base B is inclined to the back of the case, as shown in Fig. 2. Upright parallel sides B are formed on the sides of the base and extending only part way the length thereof, said sides having each an outwardly-extended lug b at right angles thereto. (Shown best in Fig. 3.) The right-hand lug b ,viewing Figs. 1 and 3, has erected thereon an upright stand 6 having a slot 3 in its foot registering with a slot 4 in the lug, the latter having depending ears 5 below the slot supporting a pin 5, Fig. 3, on which is fulcrumed an L-shaped lever 6', the lower end of which extends inward through the adjacent side B of the frame. At its upper end the lever has a cam portion 6", which is normally held against a projecting rest 6 0n the stand by a spring 8, fast at one end on the frame and at its other end attached to the inturned end of the lever. A prick-pin or punch 5 is pivotally connected at its lower end to the inturned arm of the lever, the pointed upper end of the punch playing easily through a hole g in a guide, shown as a narrow plate g extended from one to the other of the frame sides B and rigidly secured thereto. On its inner side the case-door is provided with an actuator, shown as a beveled enlargement 6" on the free end of an arm 6 attached to the door and so located that when the door is shut said enlargement will pass between the rest 6 and cam portion 5 moving the latter outward, and thereby swinging the bent lever If to elevate the punch b and punch a hole in the recordsheet carried by the record-cylinder to be described. After so operating the punch the actuator moves beyond the cam portion and the spring 8 returns the lever and punch to normal position; but when the dooris opened the actuator again operates the lever I)", as described, and another record is made on the record-sheet.

The lever 5, its punch or prick-pin, and the cam portion 6 constitute the telltale device operated by the actuator I) whenever the door of the case is opened or shut.

I have herein shown the recording cylinder or drum D as having its cylindrical surface corrugated, Figs. 1, 3, and 6, and so arranged that when in operative position the grooves (Z will be opposite the several styluses or punches to be described, such a cylinder being shown in United States Patent N o. 527 ,304, it being understood that the record-sheet R will be wrapped around the cylinder and held thereon in any suitable manneras, for instance, by elastic bands.

The telltale-punch b is arranged near one end of the cylinder to perforate the sheet along a certain line or path which will indicate opening or shutting of the door of the case. At its right-hand end the cylinder is rotatably supported on a spindle .2, Figs. 3, 3. and 4, having a collar 50 and screwed into a plate 7 ,attached to the inner face of the stand 7f. The worm-gear .2 having a hub 2, rotatable on the spindle 2, the crank-arm .2, having a squared boss .2", loosely mounted on the hub 2 and spring 2", mounted on the said boss between the gear and the crank-arm .2 and turning with the latter are and may be all substantially as shown in United States Patent No. 570,241, dated October 27, 1896, and operate as therein provided, the spring bearing on an annular friction-surface z of the gear .2 It will be obvious that the driving member, comprising the gear 2 arm 2, and spring 2 will turn upon the spindle .2 irrespective of the tension of the spring, the latter normally causing the arm to rotate in unison with the gear, while permitting rotation of the crank-arm independently of the gear, when it is desired to turn the cylinder D on its axis for adjustment or to inspect the record-sheet. The crank-pin 2" is adapted to enter a recess 10 in the adjacent end of the cylinder to rotate the latter in unison with the crank-arm. Below the gear 2 the stand 7) is provided with bearings 20 for a shaft 21, adapted to be connected in any usual manner (and forming no part of my invention) with the clock mechanism C, said shaft having fast upon it a worm 22 in mesh with and to rotate the worm-gear z to thereby transmit rotative movement to the cylinder D, the latter having central sockets in its opposite ends, one for the spindle e and the other for a movable spindle to be described. The left-hand lug b has secured upon it an upturned stand b, branched or forked at its upper ends to form bearings 6 for a slidable spindle 7), located opposite and in alinement with the fixed spindle 2. At its inner end the spindle 7) is reduced, as at I), to enter a hole or socket in a boss d on the adjacent end of cylinder D, and a controlling-pin 5 extending rigidly from the spindle at right angles to it, passing up through a locking-slot 15 16 in a locking-plate 6, attached to the tops of the bearings I). (See Figs. 1 and 3.) A spring .sis attached to the outer bearing L and at its free end presses against the pin 6 tending to throw the same in the direction of arrow 12, Fig. 3", so that when the spindle is pushed inward to operative position and the pin is opposite the notch 16 of the slot the pin will be thrown thereinto to lock the spindle from accidental retraction. This condition of affairs is shown clearly in Fig. 1, and it will be manifest that in order to remove the cylinder the pin 71" must be pushed back against the spring out of the notch 16 and into the slot 15 and then moved outward in the slot, thereby retracting the spindle I) and disengaging it from the cylinder, which latter may-then be withdrawn from spindle z and crank-pin .2" and removed from the apparatus.

Inasmuch as a watchmans stations are more whereby the watchman can energize the mag:

or less Widely separated in different parts of a building or group of buildings, the stations are arranged in electrical connection with the time-recorder, which may be located in the oflice or other central location, and in my present invention I have provided novel and simple means for mounting the electromagnets'by or through the armatures of which the records of the different stations are made upon the record-sheet R. The various novel features of this portion of my invention will now be described in detail, it being first stated that the guide g is located just below the center of the cylinder D and is provided with a row of guide-holes g for the several Styluses or punches, one being operated from each station of the system.

Ihave for simplicity and convenience herein arranged the magnets in two groups, each group being mounted on a separate plate, said plates M and N being attached to the tops of the frame sides B by screws 19, Fig. 1, the plates being located symmetrically on opposite sides of the guide g As the arrangement of the magnets on each plate is the same, only one need be described in detail, and referring to the drawings the plate M is provided with two rows of staggered countersunk holes m through each of which a screw m is passed and screwed into the core-head m of each magnet M of the well-known horseshoe form. By reference to Fig. l it will be seen that by this arrangement the magnets are very compactly arranged, a coil of one occupying a portion of the space between the coils of the next adjacent magnet. One end of the coil, as of, Fig. 2, of each magnet is electrically connected in any suitable manner with the core-head. m, and the other end m is carried to one of a series of bindingposts mi mounted on a strip of vulcanite, hard rubber, or other insulating material m secured to the upper surface of the plate M. Inasmuch as the latter is made of metal, it serves as a common conductor for the coil ends m of the several magnets and in practice is connected with a wire 33, Fig. 1, forming a part of the main station-circuit. Two stations S and S are indicated diagrammatically in Fig. 1 connected with the main circuit by wires 3 k and with the binding-posts m by wires 35, it being understood that one of the electromagnets M will be included in each station-circuit 33 34: 35, and at each station a magneto device of usual construction may be located,

net of that circuit.

Instead of a magneto device a common pushbutton may be used at each station to temporarily close the circuit, and in that case abattery or other source of power B would be included in the main line-wire 33.

As shown in Fig. 2, the several magnets project from the rear side of the supporting-plate M toward the frame-base B, on which the several armatures are mounted, as will be described.

By removing a magnet carrier or plate, as M or N, an entire group of magnets can be withdrawn from the apparatus without disarranging any of the circuits, and any one of the group can be inspected, repaired, or renewed, as may be necessary.

A transverse bar M is secured to the base at its lower end, having transverse slots m and a longitudinal intersecting groove m and at the upper end of the base a similar bar N 2 is secured and similarly slotted and grooved, the transverse slots in each bar corresponding in number and position to the magnets of the nearer carrier-plate M or N. A fulcrum-rod m is extended through the'groove m and suitably held at its ends, the rod crossing the several slots m which, as shown in dotted lines, Fig. 2, are deeper than the groove. A guide-bar M is secured to the base B beneath the guide g and is provided with a series of deep transverse slots on, alternate slots being in alinement with the slots m of the bar M while the intervening slots are in alinement with the slots n of the bar N the guide-bar M serving to guide the movement of the free ends of the two series or groups of armaturelevers to be described. The fulcrum-rod n pivotally supports a series of depending armature-levers a which are long enough to pass through the slots m of the guide-bar M and project slightly below it, while a similar series of armature-levers m are fulcrumed on the rod m and extend upward therefrom through the slots 777/ and slightly beyond them, as shown in Figs. 1 and 2, each lever of a series extending back of one of the magnets of the corresponding group and having attached to it an armature proper, m or n, opposite the magnet. The transverse slots in each end bar M and N laterally space the levers fulcrumed on the pin, extending longitudinally of the bar.

The armatures are made of broad flat pieces of iron, each longitudinally grooved at 60, Fig. 9, to slip snugly onto the lever m and secured thereto in a novel and cheap manner.

Holes 61 are made in the armature-lever, and

when the armature is positioned thereon a pointed tool or die is forced into the under side of the armature at each side of the lever opposite one of the holes to force a portion '62 of the metal of the armature inward and overlapping the edge of the hole 61, as clearly shown in- Fig. 9. The armature is thereby ward the back of the case A, tending to hold the free ends of the levers m on the bottoms of the slots on), while the weights 97/ project toward the front and act in a similar way for the levers 02/ Referring to Fig. 5, the weight is slotted at 63, and the lever is forced thereinto and suitably riveted in position.

WVhen a magnet of either group is energized, its armature is attracted and the lever attached thereto is swung toward the recordcylinder D, the slots on? being of suflieient depth to cooperate with the free ends of the armature-levers at all times, thereby preventing any lateral movement or displacement of said levers. Each armature-lever has pivotally connected with it near its free end a punch or stylus, herein shown as a round steel rod 1), sharpened to a point 32 at its outer end, to penetrate the record-sheet and extend into one of the grooves (Z of the record-cylinder when the corresponding magnet is energized, as shown in Fig. 6. A stop is provided to prevent undue movement of the punch or stylus, and herein I have shown the stop as a sleeve p, surrounding the pointed end of the rod 12 and permitting the point to project far enough beyond it to properly punch the sheet, but not to engage the bottom of the groove in the cylinder, as the end of the stop engages the ribs at each side of the groove, and thereby limits the penetrative movement of the point.

In my present apparatus the several styluses are so arranged that they are opposite every alternate groove of the cylinder, so that the sleeve of one stylus will not interfere with those of the adjacent styluses. The sleeve also serves to position and guide the free end of its stylus, as the sleeve slides freely in one of the holes, of the guide g hereinbefore described.

Any suitable means may be employed to attach the sleeve to the rod p; but herein I have shown a novel form of attachment. (Illustrated in Figs. 6 and 7 The sleeve is bored through near its lower end, as at 712, and when the rod 19 is pushed through it to the proper point oppositely-acting dies are passed through the holes 2) and forced against the opposite sides of the rod, slightly flattening it and expanding the metal laterally within the sleeve, between the holes thereof. Thus the sleeve is immovably secured to the stylus at the desired point.

I have also devised a novel pivotal connection between each armature-lever and its stylus or punch, (shown in Figs. 5 and 8,) it being noted that the lever is of greater depth than thickness. A hollow mill is applied to the side of the lever near its free end and two opposite segmental grooves 7 0 are made therein, leaving a central stud 71, the mill being shaped to leave a reduced neck '72 on the stud, while the outer walls of the segmental grooves are slightly counter-bored to leave shoulders 73. The end of the pin is flattened, as at 11 and bored to slip onto the stud or post 71. A segmental apertured washer 74 is then placed on the neck 72, and its ends rest on the shoulders 7 3, after which the end of the neck is upset, as at 75, Fig. 8, onto the washer, and the metal of the lever is also upset, as at 76, over the outer edge of the washer, holding the latter firmly in place, it in turn retaining the rod on the stud 71, while the grooves permit the requisite relative play of the rod and lever when the latter is actuated.

By employing the form of pivotal connection described and by the means for holding the armatures on their levers and the stopsleeves on the Styluses I do away with a large number of small pins, rivets, or screws and obviate any possibility of separation of the different parts.

Referring to Figs. 1 and 2, I have shown holders B for the bunch of wires 35, leading from the stations to the binding-screws of the two groups of magnets, the holders being located at the upper and lower ends of one of the frame sides B, and they are shown in dotted lines, Fig. 2, inasmuch as they are adjacent the left-hand side B, viewing Fig. 1.

An index I is secured to the top of the stand to project inward over the cylinder 1) to assist in setting the latter at the proper point when the record-sheet R is secured thereto.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be varied or modified in different particulars and details by those skilled in the art without departing from the spirit and scope of my invention, one practical embodiment thereof being described and illustrated in detail herein.
