CLOCK MECHANISM FOR TlME-RECORDERS.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed March 18,1901. Serial No. 51,573-

To ail whom it may concern:

Be it known that I, WILLARD LE GRAND BUNDY, a citizen of the United States, and a resident of Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Clock Mechanism for Time Recorders, of which the following is a specification.

My invention relates to clocks, particularly to clocks used in Workmens time-recorders.

It has for its object to simplify the con struction of the mechanism for bringing the workmans time-card on the printing-line in workmens time-recorders, known as cardmachines, to make said time-recorders easy of operation and to lessen the chances of any mistakes being made upon the Workmans time-card in the printing of his arrival and departure.

It has also for its object to simplify the construction of clocks known as calendar clocks.

I have shown my improvement in the form preferred for use in workmens time-recorders, known as card-machines, although in many of its features the invention could be used in various other machines.

In the drawings I have shown the preferred form and will now proceed to describe the same as embodied in a clock for use in cardmachines.

Referring to the drawings, which show the preferred form of my improvement as embodied in clocks for use in card-machines, similar figures represent similar parts.

Figure 1 is a front view showing a dial and a portion of the mechanism for raising or lowering a cardholder. Fig. 2 is a front view of my improved clock with the dial removed, showing a portion of a disk with the days of the week imprinted thereon and mechanism for rotating the same. Fig. 3 is a top view of my improved clock mechanism looking downward from the top. Fig. 4 is a view of my improved clockmechanism with the dial and front plate removed.

In the drawings, 1 is a clock-dial with a portion 2 cut away, so as to permit the day of the week, which is on the dial 1.7, to be seen through it.

3 is a workmans time-card which is carried in the card-holder 41, supported on the supports 42 42, and which is raised and lowered by my improved mechanism, hereinafter described.

Referring to Fig. 2, 4 is an eccentric cam fixedly secured to the shaft, upon which is carried the hour-hand clock, so that the cam will make one complete revolution every twelve hours or as often as the hour-hand makes a complete revolution of the clockdial. 5 is an arm fixedly mounted upon the rock-shaft 6, which also carries a double arm 7. The rock-shaft 6 is loosely mounted in the plates 8 9, in which the entire clockworks are mounted. This shaft 6, carrying the arms 5 and 7, is so loosely mounted in the shaft that the arms 5 and 7 will by gravity always seek the lowest position. 43 and 44 are the gear-wheels supported on the shaft, to which is attached the mainsprings operating the clock. 10 is a supplemental spring which rotates shaft 1 1, on which is fixedly mounted gear-wheel 12, which rotates fly-wheel 13 through a chain of gearing 14, 15, and 16. As shown in Fig. 4 in the drawings, the spring 10 is not permitted, except at a predetermined time, to exercise its operation, by reason of the locking device, which is as follows: Arm 18 is loosely pivoted to plate 8 at 18 so that by gravity it will seek its lowest position. Arm 18 has a portion 19 and 22 bent over at its extreme oli' end and near its center, so as to engage in a dent on the plate 20, fixedly secured to the shaft 21, and a cut-out 23 on the plate 24, fixedly secured to the shaft 25, by means of which the chain of gearing operating the governor-wheel 13 is prevented from operating except when released by means hereinafter described. 17 is a dial fixedly mounted on the shaft 26, upon which dial is printed the days of the week in duplicate with the letters A. M. and P. M. to designate fore and after noon. Upon the shaft 26 is also fixedly mounted the eccentric plate 27 and the toothed gear 28, by means of which the dial is rotatedor locked in position through the operation of spring-pressed pawl 29. Mounted upon the outer end of shaft 25, which carries gear 14 and which extends through plate 9, in which the entire mechanism is inclosed, is fixedly secured gear 30, which engages with and rotates gear-wheel 31, on which are mounted two studs 31 31, which engage with and rotate toothed gear 28, fixedly secured to the shaft 26, which also rotates the eccentric plate 27 and the dial 17. The teeth on the gear-wheels and 31 are in the ratio of one to two, so that upon every complete revolution of the gear 30 the gear 31 is revolved onehalf and through means of the studs the gear 28 is rotated one tooth. Mounted on plate 9 is a shaft 32, upon which is loosely mounted, so as to fall bygravity, the arm 33, which arm carries at its outer end the stud 33, which rests upon the eccentric plate 27 and which is raised or permitted to seek its lowest osition, according to the position in which t is eccentric plate 27 remains. The arm 33 earrles about midway a rod 34, which is connected at its lower end toan arm 35, one end of which is loosely mounted in plate 9 at 36. This arm also has supported on it arm 37 the lower end of which is pivoted near the center of arm 38, one end of which is pivoted in the frame or box in which the clock is inclosed, the other end of which supports, through the link 40, the card-rack. The mode of operation of my improvedclock is as follows: Every twelve hours or at twelve oclock the plate 4 reaches a position which raises the arm 5 and rocks rock-shaft 6, raising arm 7, which arm strikes against lug 18 on gravity-arm 18 and raises gravityarm 18 so as to unlock the portions 22 and 19 from the plates 24 and 20, respectively. The supplemental clock-spring 10 then begins to operate and rotates the chain of

gearin

14, 15, and 16 and the governor gear-whee 13. At the same time the gear 30 on the extreme end of the shaft 25 is rotated one revolution,- thereby revolving the gear 31, upon which is mounted the stud 31*, one stud of which engages with the toothed gear-wheel 28 and revo ves it one tooth. The toothed gear-wheel 28 being fixedly secured to the shaft 26 when it is revolved, it also revolves the dial-plate volved and the stud 33 of the arm 33 ,resting out 2 on the clock-face 1.

u on the outer periphery of the eccentric p ate 27, is raised, thereby raising the cardrack one point through the raising of the

rods

34, 35, 37, and38, so as to bring the portion of the card markedA.M. or PM. on the printed line A A, as shown in Fi 1 of the drawings. The printing-line on t e card is at Sunday P. M., as is also shown by a cut- Immediately after twelve oclock the cam-plate 4 permits arm 5 to dro to its lowest position, and at the same time t e gears 14, 15, and 16 are locked and the supplemental spring is restrained from operating. The eccentric plate 27 is so arranged that between Sunday P. M. and Monday A. M. the stud 33? will be raised to its farthest position from the shaft 26 upon which the eccentric plate 27 is carried, and

immediately after having been raised to its farthest position it will be permitted to drop by gravity to its lowest posltion or to its position nearest to the shaft 26, upon which the What I claim as new, and desire to secure by Letters Patent, is-
