WILLIAM J. LANDON, OF SEATTLE, WASHINGTON, ASSIGNOR OF ONE-THIRD TO JOSEPH R. WILCOXON, OF SEATTLE, WASHINGTON.

TIME-RECORDER.

Application filed January 24, 1916.

To all whom it may concern:

Be it known that I, TILLIAM J. LANDON, citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a certain new and useful Improvement in Time-Recorders, of which the following is a specification.

My invention relates to improvements in time recorders, and the object of my invention is to provide time recorders which shall be simple in their plan of construction, reliable and efficient in their operation and which shall be especially adapted each to be actuated by electrical mechanism that may be connected in an electric circuit that is controllable by an electric switch that may be operated only by the manipulation of a key that may be carried by a watchman, said time recorder being disposed in a position wherein it will be inaccessible to said watchman, thus to prevent an unauthorized person from operating or interfering with the operation of said time recorder and whereby the performance of the work of said watchman may be checked.

I accomplish this object by devices illustrated in the accompanying drawings wherein Figure 1 is a plan view of a clocklike structure embodying my invention with its front glass removed better to expose the whole of its dial; Fig. 2 is another plan view of the same with both the said glass cover and said dial removed to expose in ternal operative parts thereof; Fig. 3 is a view on an enlarged scale of the same in radial section on broken line 00, w of Fig. 1; Fig. 4 is a partial view in section of the same on broken line 3 12 of Fig. 3, showing some parts thereof in side elevation; Fig. 5 is a plan view of a paper dial that is adapted to be removably embodied in the same; Fig. 6 is a fragmentary view in side elevation of an external portion of said structure showing details thereof, and Fig. 7 is a perspective view of another detail of said structure.

Referring to the drawings, throughout which like reference numerals indicate like parts, a clock case 8 of well known cylindrical form contains a marine clock movement 9, parts of which only are shown, which movement 9 is secured to the inner side of the back wall of the clock case 8 with its Specification of Letters Patent.

Patented Aug. '7, 1917.

Serial No. 74,027.

center-shaft 10 disposed concentrically with the cylindrical wall of said clock case 8.

The center-shaft 10 (which is operated to make one revolution each hour and which projects from the front side of the movement 9 to a point near a front glass cover 11), like ordinary clocks, is provided on its outwardly projecting portion with a pinion 12 which is disposed to engage with a gearwheel 13 which is in fixed association with a pinion 14, said gearwheel 13 and pinion 14 being rotatably mounted on a stud 15 secured to the front plate of the movement 9; and in front of the pinion 12 on the centershaft 10 is freely mounted a sleeve 16 upon the inner end portion of which is fastened a concentrically disposed gearwheel 17 which meshes with the pinion 14.

The relative diameters and numbers of the teeth of said pinion 12, gearwheel 13, pinion 14 and gearwheel 17 are such as will cause said sleeve 16 to make one twelfth of a revolution while the center-shaft 10 revolves once so that said sleeve 16 will revolve once in twelve hours.

On the sleeve 16, in front of and spaced from the gearwheel 17 is a disk 18, which is provided with pointed projections 19 which extend outwardly from its front side whereby when a dial of paper or card-board, like the dial 20shown in Fig. 5, is concentrically disposed on said sleeve 16 and pressed against the front surface of the disk 18 then the pointed projections 19 will pierce said dial 20 to secure it against a rotative movement with respect to said disk 17 as shown in Fig. 3.

In order to fasten the dial 20 in its position against the front surface of said disk 18, I have provided a curved clip 21 made of thin springy sheet metal of a form shown by a perspective view in Fig. 7, which clip 21 is provided with a hole 22 of a diameter slightly larger than the diameter of the sleeve 16, and which is further provided with a slot 23 which constitutes a sidewise extension of said hole 22, the width of said slot 23 being slightly larger in diameter than the diameter of the bottom of a groove formed in the periphery of the sleeve 16 in a position in front of and spaced from the front side of the disk 18, whereby said springy clip 21. may be removably disposed on said sleeve 18 with its opposite ends in yielding engagement with the front side of the dial 20, while the opposite sides of the slot 23 are in engagement with the side walls of said groove, in an obvious manner, to hold the dial 20 in its position against the front side of said disk 10.

Thus a. rotation of the disk 18 will carry with it and revolve the dial 20, which dial 20 is inscribed, as shown in Fig. 5, with eight circular lines the spaces between adj acent ones of which represent the different days of a week, and is further inscribed with twelve equi-distantly disposed radial lines which intersect all of said circular lines, which radial lines are indicated by numbers one to twelve inclusive, as shown.

Projecting inwardly through an opening 24 formed in the cylindrical wall of the clock case 8, near the front thereof, is one arm 25 of an angle bar and one arm 26 of another angle bar, which two arms 25 and 26 are spaced from each other, while the other arms 27 and 28, respectively, thereof are bolted together onto the outer side of said cylindrical wall of the clock case 8 by means of bolts 29 as shown.

The arm 25 is provided with a slot 30 which extends through it for a greater portion of its length, and an iron block 31 is disposed to be adjustably movable against the rear side of said arm 25 where it is slidably secured by means of shouldered screws 32, which extend through said slot 30 and whose shanks by their engagement with the sides of said slot 30 serve to guide said iron block in its movement from one position to another in a lengthwise direction of said arm 25.

Extending through the externally disposed arms 27 and 28 and the cylindrical wall of the clock case 8 is a hole disposed to register with the adjacent end of the iron block 31 and disposed to extend through said hole is a spindle 33 whose inner end is fastened to said adjacent end of said iron block 31 by means of which spindle 33 said iron block31 may be moved to different positions with respect to the length of said iron block 31, said spindle 33 being provided with a knob 34 and with seven grooves 35 which grooves 35 are spaced apart for distances corresponding to the width of the seven spaces between the circular lines inscribed on the dial 20.

In order releasably to fasten the iron block 31 at any desired one of seven different positions I have provided a spring 36, made of spring wire to be of the form shown in Fig. 6, which is secured beneath the head of the rearward one of the screws 29 to extend forward therefrom to a position that will adapt it yieldingly to engage with the side of the spindle 33, whereby it may enter a required one of the grooves 35 thereon when said spindle 33 is moved in a lengthwise direction to a desired position.

The iron block 31 is provided with an integral boss 37 which projects through the slot 30 in the arm 25 and extending through said boss 37 and through said iron block 31 is a hole which serves to guide a pointed punch 38.

The iron block 31 serves as a heel-piece for a pair of electromagnet spools 39 which are fastened to the rearward side of said iron block 31 to extend rearwardly therefrom and the rear ends of said magnet spools 39 are rigidly connected by a yoke 40, of non-magnetic metal, to the rear side of which is a screw stud 41 upon which is slidably mounted an armature 42 to the central portion of which is secured the rear end of said pointed punch 38 which extends forwardly through a hole in said yoke 40 and thence between the magnet spools 39 into and through said boss 37.

Surrounding said pointed punch 38 in that portion between said armature 42 and said yoke 40 is a helical spring 43 which serves normally to keep said armature 42 in its rearwardmost position.

The outer end surface of the boss 37 is disposed. to register with the rear side of a dial 20 when said dial 20 is disposed against the front of the disk 18.

The arm 26 is provided with a narrow groove 44 on its rear side, which groom 44 extends lengthwise thereof in a position so that the pointed end of the pointed pun'cII 38 will be projected thereinto when the armature 42 is moved toward the poles of the magnet spools 39 in response to the passage of an electric current through the helices of said magnet spools 39, said arm 26 being disposed to extend parallel with the arm 25 and in front thereof at such distance as will permit the dial 20 to revolve adjacent to the rear side of the arm 26 so that said dial 20 may engage with it when said dial 20 is punctured by the point of the punch 38.

As represented in Fig. 2, the terminals 45 and 46 of the electric helices of the magnet spools 39 are connected respectively with connecting posts 47 and 48 to which is connected an electric circuit which includcs a battery 49 and a circuit breaking switch 50; which switch 50 may be adapted to be operated only by means of a special key, whereby at required times the helices of the magnet spools 39 may be energized to cause the pointed punch 38 to puncture a dial 20.

The operation of the time recorder thus illustrated and described may be explained as follows:

The time recorder is disposed to be inaccessible to a watchman and then its connecting posts 47 and 48 are connected to an electric circuit in which is included a battery, as battery 49, and a circuit switch, as circuit switch 50, which circuit switch may be disposed at a desired point that is accessible to a watchman, and which circuit switch may be operated only by the manipulation of a special key which is carried by said watchman; and then a dial, like the dial 20, is disposed in the manner illustrated in Fig. 3, whereupon the clock movement 9 is wound up and the dial 20 is set so that the radial lines thereon shall be disposed with relation to the point of the punch 38 to indicate the correct time; then the spindle 33 is moved to cause the spring 36 to fall into that one of the grooves 35v as will dispose the point of the punch 38 to register with that one of the spaces between the circular lines of the dial 20 that represents the correct day of the week, and thereupon the glass cover 11 is placed in its normal position, as shown in Fig. 8.

With the time recorder thus installed, whenever a watchman with his special key operates the switch (as switch momentarily to close said switch, which is normally open, then the pointed punch 38 will be actuated, in an obvious manner, to puncture the dial 20 at that point thereon that will correctly indicate the time that said switch was operated by' said watchman.

Obviously, changes may be made in the details of my invention without departing from the spirit thereof.

What I claim is:

1. In a time recorder of the class described, a casing, a clock mechanism therein, a sheet dial rotated by the clock mechanism, guide bars within the case, an electrically-operated punch slidably mounted in the guide bars, a stem carried by the punch and projecting outwardly of the casing, said stem having spaced annular grooves therein,

and means selectively associated with said grooves whereby the punch may be held in different radial positions relative to the dial.

2. In a time recorder of the class described, a casing, a clock mechanism therein, a sheet dial rotated by the clock mechanism, guide bars within the case, a block slidable in said guide bars, electromagnets supported by said block, an armature therefor, a punch carried by the armature adapted to pierce the dial, a stem having a plurality of annular grooves connected at its lower end to said block, and a spring carried exteriorly' of the casing adapted for selective positioning in the grooves for holding the punch in difierent radial positions relative to the dial.

3. In a time recorder of the class described, a casing, a clock mechanism therein, a sheet dial rotated by the clock mechanism, a pair of angle members, each having one leg superposed on the casing eXteriorly thereof and secured in position, the other legs being disposed within the casing in spaced relation to constitute a guide, a block slidable in said guide, electromagnets supported by said block, an armature therefor, a punch carried by the armature adapted to pierce the dial, a stem having a plurality of annular grooves connected at its lower end to said block, and a spring carried exteriorly of the casing adapted for selective positioning in the grooves for holding the punch in different radial positions relative to the dial.

In witness whereof I hereunto subscribe my name this 12th day of January, A. D.
