Application June 17,

8 Claims.

This invention relates to a workmans time recorder of the type in which a plurality of records are printed on a time card each day for a predetermined period, such as a weekly period of seven days or a bi-weekly or semi-monthly period of fourteen to sixteen days. In such recorders, it is customary to shift the card relative to the printing point in both vertical and horizontal directions and these shifts are usually automatically effected and controlled.

With one type of card, the shift is horizontal during the working period and vertical from day to day. With another type of card, the shift is vertical during the working period and horizontal from day to day. With either type of card, the card may be either raised or lowered at each vertlcal shift.

It is the general object of our invention to provide -a card time recorder so constructed that it may be readily adapted to use cards with many different record arrangements. Some eighteen such different arrangements are in more or less common use.

In the carrying out of our invention, we have constructed our improved recorder in two easily combined units. The main unit contains the printing and impression devices, the ribbon mechanism, the program control devices, if any, and the time-controlled actuating mechanism for the printing and program devices; also the card chute and the supports on which the chute is horizontally slidable.

The second or auxiliary unit commonly contains the card lift or abutment, a member connected to move the card chute horizontally, and mechanical means to shift the abutment and to move the card chute in definite and predetermined relationship.

Furthermore, we make the auxiliary units interchangeable in the .main unit, so that a recorder may be readily adapted to use any desired card and to assemble records thereon according to any desired system. This result is attained by selecting any appropriate auxiliary unit and installing it in the main unit, the recording mechanism of which latter unit remains unchanged for all different cards and for different distributions of records.

Another feature of our invention relates to an improved construction which permits the card chute to be manually shifted horizontally out of normal recording position when necessary but which promptly returns the card chute to normal position as soon as released.

.Our invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

Parts of the main unit of a time recorder, together with two different auxiliary units, are shown in the drawings, in which Fig. 1 is aperspective view of parts of a recorder, together with an auxiliary unit for use with a card in which the shifts are horizontal during a working period and in which the card is raised at the end of such working period;

Fig. 13 is a similar view of a time card adapted for use in an auxiliary unit such as is shown in Fig. '7; and

Fig. 14 is a detail view of a feeding member to be described.

Referring to Figs. 1 to 6, we have shown parts of the main unit of our improved time recorder including a side frame member 20, a fixed cross rod 2| on which a card chute 22 is horizontally slidable, an actuating lever 23 pivotally mounted on the frame 20 and connected by 'a link 24 to any suitable actuating mechanism by which the lever 23 is given a rocking movement once each minute or other predetermined and regular time interval. This actuating movement may be Pro duced by any usual time-controlled mechanism such as a solenoid, the circuit of which is closed once each minute.

A latch 25 is pivoted to the end of the 1ever.-2.3 and normally clears a pin 26 on an upright. and vertically sliding member 21 forming a partof the auxiliary unit. The upper end of the slide 21 is detachably connected as by a screw 2| to makin a link 29 pivoted at to a U-shaped member 3| A spring 35 tends to move the slide 21 downward and also to swing it rearward out of the path of the latch 25. At its lower end the slide 21 is slotted as shown in Fig. 14 and embraces and is guided by a cross shaft to be described.

The card chute 22 has side portions 36 and 3! to receive the edges of a card C of the type shown in Fig. 12, and also has an offset prolection 38 with a stud 39 inserted therein.

' All of the parts thus far described, with the exception of the stud 26 and slide 21, are parts 01' the main unit of our improved time recorder and-the details of such parts per se form no part of our present invention.

The auxiliary unit A shown in Figs. 1 to 6 comprises a sub-frame 40, preferably of sheet metaland U-shaped in horizontal cross section I andopen at the top and bottom thereof. A cross rod 4| rigidly connects the spaced rear edges of the sub-frame 40 and the sub-frame is secured to the end frame 20 by a plurality of screws 42. Two such screws are shown in Fig. 1 and additional similar screws are shown in Fig. '7 but are covered or concealed by other parts in Fig. 1.

By removing the screws 42 and the screw 28 previously described, and by disconnecting a pair;of wires 44 and 45 from certain circuitclosing contact members 45 and 41 to be described, the entire auxiliary unit A may be removed from the time recorder and may be replaced by a corresponding but different unit, such asis shown for instance in Fig. 7.

Further describing the unit shown in Figs. 1 to 6, a cross shaft is rotatably mounted in the ends of the sub-frame 4|] and is provided at one end with a mutilated pinion 5| which engages a rack 52 carrying a slide 53.'which in turn supports a card rest or abutment 54. A resilient contact member yieldingly supports the slide 53 and abutment 54 and when depressed by the card, the contact'mem'ber 55 first engages the contact member 46 previously described and thereafter engages the contact member 41, thus completing the connection between the wires 44 and 45 which control the impression mechanism of the recorder. This mechanism may be of the type shown in the prior patent to Watkins, No. 2,102,771.

The mutilated pinion 51 is preferably made in two parts as shown in Fig. 6, with the omitted teeth in the two parts staggered to the extent of two teeth, as clearly shown in Fig. 6. The rack 52 has an auxiliary tooth 58 (Fig. 5) secured at one side thereof and adaptedto engage the teeth of the pinion portion 5la when the rack is released by the mutilated pinion and falls to the bottom of its path of travel.

Fora more complete description of the coac tion'. of this type of rack and pinion, reference is made to the prior patent of Deane and Dell, No. 2,286,902.

A stop 59 (Fig. 1) fixed to the sub-frame 40 determines the lower position of the rack 52 and abutment 54 when the rack is released.

The shaft 50 is provided with a ratchet wheel 60 engaged by a feed pawl 5| pivotally mounted 21 previously deis, however, held inoperaon the vertically movable slide scribed. The pawl 6| tive in this type of unit until the end of the twenty-four hour or working period by a stud 62 thereon which is engaged by a cam 53 formed on the oifset arm of a slide 64 having a screwand-slot connection to one end of the sub-frame an. So long as the slide 84 is in its normal or lowered position, the cam 63 engages the stud 62 and withdraws the pawl 6| as it is lifted, so that it cannot move in and engage the next higher tooth of the ratchet Wheel 66.

At the end of the Working period, however, the slide 64 is raised by mechanism to be described and permits such engagement, whereupon the shaft 56 and pinion 5! are angularly advanced one space.

The means for shifting the card chute 22 horizontally to successive in and out positions during the day comprises an upwardly extending arm 65 (Fig. 1) having a slot 61 to receive the stud 39 on the offset projection 38 of the card chute.

At its lower end, the arm 66 (Fig. 2) is pivoted at 68 to a link 69, which in turn is pivoted at .78 to the horizontal arm of a bell crank TI. The bell crank H is fixed to'a cross shaft 12 (Fig. 1) which is supported in fixed bearings 13 in the sub-frame 40 and which has a segment gear or circular rack 15 also fixed thereto. a

The gear 15 has a starting tooth 'lfi at one side thereof and engages a double mutilated pinion 11 mounted on a second cross shaft 78. The shaft 18 is supported in bearing brackets 13 fixed to one end portion of the sub-frame 40 andthe shaft is provided with a ratchet wheel 86 (Figs. 3 and 4) which is engaged and intermittently fed in the direction of the arrow a (Fig. 3) by a vertically disposed feed pawl 82. The upper end of the pawl 82 is loosely pivoted at the outer end of a stud 83 which is fixed in the vertically movable slide 21 (Fig. 1) previously described.

A tension spring 84 is connected at one end to the pawl 82 and at its other end to the stud 83 and tends to'swing the pawl 82 from the full line to the dotted line positionin Fig. 3 as the slide 21 is raised. A spring-pressed holding latch85 prevents rearward rotation of the ratchet wheel 80 and cross shaft 18. An offset depending lug 86 (Fig. 4) loosely embraces the shaft 56 previously described and thus prevents lateral displacement of the feed pawl 82.

A reversed ratchet wheel 88 (Figs. 3 and 4) is mounted on the cross shaft 13, and the teeth thereof are normally engaged by a locking pawl 89 mounted on a fixed pivot 9|] on a bracket 90a secured to the'sub-frame 40; An offset arm 92 on the latch 82 engages the tail 93 of the pawl 89 as the ratchet wheel 80 is advanced but clears the pawl before the next tooth on the reversed ratchet wheel 88 has reached locking position. Unauthorized advance of the chute-moving shaft 1'2 is thus prevented.

By the operation of the feeding mechanism above described, the ratchet wheel 80 and cross shaft 18 will be advanced one space each time the slide 21 is swung to the left in Fig, 1 by the program connection. The stud 25 is then positioned in the upward path of the latch 25 on the regularly-actuated lever 23. Such advance movement of the shaft 18 rotates the mutilated pinion .H and swings the segment gear 15 downward spring 01 is connected at its lowerend to the bell crank arm and at its upper end to a stud 98 (Fig. 2) in an offset portion of the arm 66. The action of the spring 91 is to seat a stud 66a therein against the upper edge of the link 69 and to seat the lower edge of the arm 66 firmly against the horizontal arm of the bell crank II, with which it swings back and forth to shift the card chute 22.

If however, it is necessary to move the card chute backward to make an in record after an "out shift, the card chute may be pushed manually to the left in Fig. 1, thus swinging the arm 66 about its pivot 68 to the left or dotted line position shown in Fig. 2 and against the tension of the spring 91, which will immediately restore the arm and card chute to normal position when released. If, on the other hand, it is necessary to shift the card forward one space so as to make an early out record, the card chute is shifted to the right in Fig. 1 and the arm 66 moves therewith to the right to the broken line position in Fig. 2, which movement is permitted by angular movement of the arm 66 and link 69 as a unit about the pivot I0, such movement also being yieldingly resisted by the spring 91.

' A double cam 99 (Fig. 1) is mounted on the shaft 1.8 and engages and lifts the slide 64 at the end of each working period. This releases the stud 62 (Fig. 1) and permits the pawl BI to engage and advance the ratchet wheel 60, thus raising the card abutment 54 one space. At the same time the segment gear is released by the mutilated pinion 11 and swings upward to its highest position, thus shifting the card chute to the extreme left in Fig. 1.

' It will thus appear that the auxiliary unit A, permanently assembled in the sub-frame 40, comprises eifective mechanism for shifting the card chute to present successive in and out columns at the printing point and also for raising the card one space at the end of each working period.

It will be noted that the segment pinions 5| and TI have teeth omitted'on opposite sides thereof, so that they will release the rack 52 and segment gear 15 after each half revolution, and the cam 99 is made double for the same reason. For a two-week card, however, the pinion 5I will be cut away on one side only, so as to provide double the number of abutment shifts before return of the abutment to its lowest position.

As previously stated, the entire unit A may be removed from the recorder by taking out the screw 28 which connects the link 29 to the feed slide 21 and by taking out the screws 42 which secure the auxiliary unit A in the main frame and by disconnecting the wires 44 and 45 which form part of the operating circuit for the impression mechanism of the recorder.

The auxiliary unit B shown in Figs. '7 to 11 is interchangeable with the unit A shown in Figs. 1 to 6, and the parts of the main recorder unit which appear in Fig. 7 are identical with those shown in Fig. 1 and are similarly numbered.

The second auxiliary unit B comprises a subframe I00, U-shaped in horizontal cross section and having its front edges connected by a. cross rod I0 I This unit B may be secured in the main frame 20 by inserting the screws 42 in the same threaded holes in the frame 20 as were used for the unit A previously described.

A slide I02 is detachably connected at its upper end by the screw 28 to the link 29, as previously described, and the slide is provided with a stud I03 which may be swung to the left in Fig. 7 into the path of movement of the regularly actuated pawl 25.

At its lower end, the slide I02 is slotted to embrace a shaft I05 and the slide is provided with a feed pawl I06 to intermittently advance the shaft I05 and a mutilated pinion I01 which enages a card lift rack I08. A card abutment I I0 is mounted on the rack I08 and supports a card C in the card ch'ute 22. The connections between the rack I08 and abutment H0 and the electrical connections to the wires 44 and 45 are identical with those previously described, as is also the coaction of the mutilated pinion I01 and card lift rack I08, but the pinion I0! is cut away at one side only. The 'card lift rack I08 and the card abutment I III are thus released only at their extreme upper limit of travel, and such release is followed immediately by a lateral shift of the card chute to bring a different day column on the card in record-receiving position. The details of construction of these parts are as shown in Figs. 5 and 6 and previously described.

A scroll cam H2 is fixed on the shaft I05 and rotates therewith. The cam H2 underlies a cam follower block II3 (Fig, 9) on an arm II4 pivoted on a fixed stud II5 (Fig. 7) and yieldingly pulled downward by a tension spring I I5. A vertically disposed feed pawl I20 is loosely pivoted at I 2| (Figs. '7 to 9) to the arm H4 and at its lower end engages a ratchet wheel I23 on a cross shaft I24. A locking pawl I25 prevents reverse movement of the ratchet wheel I23 and shaft I24, and overfeed is prevented by a hold-back pawl I26 engaging a reversed ratchet wheel I21.

A mutilated pinion I30 (Fig. 7) is mounted on the cross shaft I24 and engages a segment gear plate I 3I having a starting tooth I32, also as previously described. The segment gear I3I is mounted in a cross shaft I34, to which a swinging upright arm I is rigidly secured. At its upper end, the arm I35 has a slot I36 to receive the stud 39 and to thereby actuate the card ch'ute 22.

A tension spring I3! is connected to a stud I38 in the lower end of the arm I35 and acts to move the segment gear plate I3I upward and to return the card chute 22 to its left-hand or initial position when the plate I3I is released by the mutilated pinion I30.

This type of unit is used with a card C such as is shown in Fig. 13, in which the horizontal shift is from one day-column to the next, and in which it is not desirable that the card chute be manually shifted to any other day-column.

Consequently, w provide a locking latch I40 (Fig. 7) pivoted at I on the gear plate I3I and yieldingly held against the rear end of the extra tooth plate I42 by a spring I43. When the segment gear plate I3I is released and swings upward, the latch I40 engages a tooth of the pinion I30 and thus locks the pinion I30 from reverse rotation and the gear plate I3I from upward movement until the teeth thereof are again engaged by the teeth of the pinion I30. Undesired shifting of the card chute to change the daily column is thus avoided.

Having briefly described the construction of this second form of auxiliary unit, the operation thereof will be readily apparent. At the end of each desired program interval, as for instance at the end of each half hour, the slide I02 and stud I03 will be shifted forward for engagement by the pawl 25, which is ordinarily lifted once each minute by the same mechanism which advances the minute type wheel. The lever 23 is the impression mechanism of the recorder.

almost immediately released and-returns to its initial position,'and the slide I02 moves downward, advancing the ratchet wheel I06a fixed to th shaft I and thus correspondingly advancing the pinion I01 to lift the card lift rack I08 and abutment H0 one vertical space. The scroll cam I I2 is also advanced.

These operations will continue until the rack I08 reaches its upper limit of travel, whereupon the rack will be released and the card abutment will fall to starting position. At the same time, the lever I I4 will be released by the scroll cam I I2 and the latch I will advance the ratchet wheel I23 and thus shift the card chute 22 to the next space to the right.

This cycle will be repeated automatically until the end of the seven-day working period, when the segment gear plate I3I will be released and the card chute will return to initial position. Records may thus be made in desired spaces on a time card such as is shown in Fig. 13, with the records for each day spaced downward along a single vertical column.

As previously explained, this unit may be removed from the main recorder unit by taking out the screw 28 which connects the link 29 to the feed slide I02 and by taking out the screws 42 which secure the auxiliary unit B in the main frame 20 and by. disconnecting the wires 44 and 45 which form part of the operating circuit of The unit A shown in Fig. l or any other desired auxiliary unit may then be substituted and made operative by inserting the screws 28 and 42 and making the connections to the Wires 44 and 45.

As stated in the introduction, there are some eighteen more or less standard arrangements of card records. It is easily and economically possible to have a supply of auxiliary units for each of these combinations on hand, while the main units of the recorder can be made up in quantity and also kept on hand ready to receive any selected auxiliary unit as called for by a particular sale and order.
