(Cl. M11- 43) 7 Claims.

This invention relates to a time recorder of the general type in which records are made on a separate card for each employee, which cards then show the time worked during each daily or other working period or the time worked on a certain job. Such recorders, producing a printed time record only, are in common use.

f It is the general object of my invention to provide an improved card time recorder which will not only provide a printed record of the actual or clock time of starting and stopping work but will also provide a punched rrecord adapted for use in a tabulating or calculating machine.

In the preferred form of my invention, these two types of records are made successively but as parts of a single registering procedure.

A further feature of the invention is the provision of means by which the set-up for the punched indication will remain unchanged during predetermined non-Working periods, such as the noon lunch period or limited periods before morning in starting time and after night out" stopping time.

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

A preferred form of the invention is shown in ihe drawings, in which Fig. 1 is a left-hand elevation of my improved recorder, looking in the direction of the arrow I in Fig. 2;

Fig. 13 is a similar View showing the feeding mechanism for the selectors for the hour units and tens columns; and

Figs. 14, 15 and 16 are detail views showing the coaction of the different selectors with their respective interponents.

Briefly described, my improved time recorder comprises a base portion having feeding mechanism by which a record card is automatically advanced, stopped in punching position, thereafter again advanced and stopped in printing position, and finally delivered from the recorder to a suitable card-receiving device.

The punching mechanism comprises sets 'of punches preferably indicating time decimally in hours, tenths, and hundredths. A separate set of such punches is provided for each of six registering periods, such as morning-in, noon-out, noon-in, night-out, eXtra-in and eXtra-out, and each of the punches in al1 of the sets has axial movement only in the base.

A further part of the recorder comprises a carriage movably mounted on the base and having time-controlled printing wheels and a stamping platen associated therewith and having also the punch-selecting mechanism shown in Fig. 6 and the interponents shown in Fig. 7. The carriage containing all of this printing and punchselecting mechanism is shiftable on the base portion of the recorder transversely to the path of card travel, and is moved automatically transversely from each registering position to the next successive registering position by suitable program and shift mechanism.

I also provide a program control for the feed of the punch-selecting mechanism, which control can be `so arranged that no selector feed takes place during certain predetermined periods. Commonly, the arrangement is such that the punch-selectors remain stationary during the entire noon lunch period and also during short periods before morning-in starting time and after night-out stopping time.

I also preferably arrange to stop the selector feed during the night or during some other nonworking interval for an additional predetermined period of such length that the aggregate lost time will total just four hours. The aggregate of all operative periods during which the punches are progressively selected will then total twenty hours out of each twenty-four hour period.

The feed of the punch-selecting mechanism is 3 actuated by a separate synchronous motor mounted on the movable carriage, and this separate motor is controlled by any usual program disc on the carriage, which disc is continuously rotated in step with the type-wheel feeding mechanism.

Having described the general features of construction of my improved time recorder, I will now describe the various parts in detail.

In Fig. 2 I have shown a plan view of the base of the machine, with certain superposed parts indicated diagrammatically. The base comprises a frame having iront and baci; frame members 29 in which a plurality of cross shafts 2| are rotatably mounted. Each of these cross shafts is provided with feed rolls 22 which underlie and support the record card and which feed it forward through the machine. Each cross shaft is provided at one end with a gear 23, which gears mesh with intervening idle gears 24 so that all of the cross shafts rotate in the same direction and at the same speed.

The gear 23 on the cross shaft 2| at the entering end of the recorder (or at the right in Fig. 2) is engaged by gear 25 on a fixed stud 25 (Fig. 9). A second gear 39 is associated with the gear 25 and meshes with a large gear 3l mounted on a main cam shaft 32 rotatable in the frame members 20.

The shaft 32 is connected through any suitable one-revolution clutch 33 (Fig. 1) to a driving motor M which may rotate continuously during a registering period or which may be started up for irregular registrations. The clutch 33 may be engaged manually by the Workman after placing his card in the machine, or the clutch may be electrically rendered operative by the act of placing the card in the machine, utilizing for this purpose any Well-known card-controlled switch device, such as that shown for instance in the prior patent to Ruttiman and Deane, No, 2,330,- 387, issued Sept. 28, 1943.

Upper tension rolls 34 are associated with the entering or right-hand feed rolls 22a (Fig. 9) and are of the same diameter as said feed rolls. Additional tension rolls 35 (Fig. 2) of smaller diameter are associated with other feed rolls 22. these tension rolls 34 and 35 are mounted on cross shafts S6 freely rotatable in bearings in bellcranks 3'! (Fig. 3) and yieldingly pressed against the driving rolls 22 and 22d by tension springs 38.

Whenever the clutch 33 is engaged, all of the feed rolls 22 and 22a are positively rotated and all of the tension rolls 34 and 255 are rotated by fricticnal engagement with their associated feed rolls.

A gate (Fig. 3) is provided for engagement by the record card C when it reaches punching position, and a second gate 46 is provided for` engagement by the card when it reaches printing position. The gates i5 and 46 are mounted at opposite ends of a supporting lever` 41 mounted on a fixed pivot 48 and by movement of which one gate is raised whenever the other gate is lowered.

The lever 41 (Fig. 3) is connected to a bent lever 59 freely pivoted on a cross shaft 5| and having a roll 52 (Fig. 9) engaging a cam 53 on the main cam shaft 32 previously described. As the cam shaft rotates, the cam 53 actuates the

levers

59 and 4'. to place the

gates

46 and 46 alternately and oppositely in card-engaging and card-releasing positions.

A card feed plate 55 (Fig. 3) is mounted on arms 55 secured to a cross shaft '51 which is provided with an operating arm 58 having a cam roll 59 (Fig. 9). The roll 59 engages a relatively large cam 60 on the cam shaft 32. A spring 6| moves the feed plate 55 yieldingly to the left in Fig. 3 whenever a recess 62 in the cam 60 receives the cam roll 59. At such times, the feed plate 55 yieldingly advances the card C previously inserted by the workman, so that the leading edge of the card will be engaged by the feed rolls 22 and 21 and vill be automatically advanced until it is stopped rst by the gate 45, which at that time is held raised by the cam l53. The card is closely guided at its ends by the frame members 20 or guides associated therewith.

After the punching operation has been cornpleted, the roll 52 passes off of the high portion of the cam 53. thus allowing the gate 45 to be lowered and the gate 46 to be raised. The feed rolls 22 will then advance the card to engage the second gate 4G, in which position it will be held while the printing operation takes plate. Thereafter the lever 5D will be again shifted by the cam 53 to reverse the gates and allow the card to be advanced by the feed rolls 22 to any suitable card-receiving device 64 (Fig, 3).

While in printing position, the card is forced upward against time-printing type-wheels W by a platen 65 which may be mounted at the upper end of a solenoid plunger 65 actuated by a solenoid coil E1. The solenoid circuit may be cardcontrolled as in Deane and Ruttiman cited and will be energized as the card is stopped in printing position. The use of the solenoid-operated platen is optional and in itself forms no part oi the present invention.

The punches P (Figs. 3 and 5) which make the perforated record in the cards are mounted for vertical sliding movement in a punch plate 1D fixed in the base of the recorder. The preferred arrangement of one unit of punches for decimal time is shown in Fig. 5, with a row of punches P! for hundredths of an hour, P2 for tenths, P3 for hour units, and P4 for hour tens. Each set of punches is thus adapted to register time by hundredths of an hour from zero to 19.98 hours.

In Fig. 2 I have indicated diagrammatically the relative locations of the punch units for six working periods. It will be understood that an entire separate set of punches as shown in Fig. 5 is provided for each registering period or position. Each of the punches for all of the registering periods thus occupies an individual position which is fixed relativo to the positions of all other punches. In this way variations in punch position which might lead to inaccurate tab-ulating are avoided, as each punch always operates in the same fixed position.

Selector' mechanism to be described is provided for holding down selected punches to give a correct time representation. The record card is forced up by a di'e plate 12 against the selected punches and thus receives perforations.

The die plate 12 (Fig, 3) is mounted on cross members 13 (Figs. 4 and l0) having depending portions 15 (Fig. l0) which are pivctally supported by the cross shaft 5l (Fig. 3) previously described. Slotted rolls 11 (Fig. 10) are mounted on the shaft 5l and constituting bearings therefor. These bearing rolls are mounted in and supported by arms 78 fixed on a cross shaft 19 (Fig. 3). An arm 8E on the cross shaft 19 has a cam roll 8l (Figs. 3 and 9) seated in a cam groove 32 in the side of a face cam 83. The arms and 18 are thus oscillated to raise and lower the die plate 12, thus perforating the record card. It will be noted that the shaft I which supports the gate lever 50 is also raised and lowered at the same time, so that the relative card-stopping position of the gate 45 remains substantially unchanged during the punching operation.

Spaced guide plates 85 and 86 (Fig. 3) constitute a vertically movable unit with the die plate 12. The guide plate 85 also serves as a stripper plate to move the card C downward and free it from the punches after perforation. n

The card C is inserted in the narrow space 81 between the die plate 12 and the stripper guide plate 85. Two pairs of the feed rolls 22 project through slots in the end portions of the die plate 12 into said card space 81, and two pairs of upper rolls 88 are mounted in the vertically movable unit comprising the

plates

12, 85 and 86. These rolls 88 coact with the feed rolls 22 in forwarding the card and in positioning it firmly against the stop gate 45.

It will be understood that the punches P are freely slidable vertically in the punch plate (Fig. 3) and are frictionally slidable in the

plates

85 and 86, and that they are each permanently aligned with an associated die opening in the die plate 12. The punches P, .if not restrained from upward movement, will be lifted by the card as the card C and die plate 12 are lifted, and no corresponding holes will be punched in the card. If, however, any punch is preventedfrom rising,

v the plate 12 will push the card upward against and past the lower end of the punch P, and a corresponding hole will thus be made in the card. A punched record for tabulating purposes will thus be produced, which record will correspond to the time when the punching operation is performed.

The operation of the selectors and interponents which hold the selected punches in operative lower position and which prevent them from rising with the card and die plate will be hereinafter described.

Clock mechanism 90 is indicated diagrammatically in Fig. 3 and may be operated by a synchronous motor 9|. Hour, minute and day typewheels W are indicated in Fig. 3 and any other or additional type Wheels or printing devices may be added.

Fig. 5 shows a set of punches designed to transform clock time in hours and minutes into decimal time in hours, tenths and hundredths. The transverse position of the punches corresponds to the numeral values 0 to 9 inclusive as indicated.

The punches PI indicate the approximate decimal equivalents of periods of from one to six consecutive minutes the full six minutes constituting one-tenth of an hour. The period up to one minute is counted zero, the two minute period is counted as two one-hundredths of an hour, and the three, four, ve and six minute periods receive the approximate decimal equivalents of four, five, six and eight one-hundredths respectively. 'Ihe punches P2 indicate tenths of an hour from 0 to 9, the punches P3 indicate hour units from 0 to 9, and the punches P4 indicate I) and 1 in the hour tens column. It is thus possible to indicate by perforations any time from 00.00 to 19.98 inclusive.

Selectors and interponents In Figs. 14, and 16 I have shown individual interponents and selectors for holding selected punches P in lowered or punching position.

In Fig. 15 I have shown a punch PI held down by an interponent engaged by a lug 96 on a selector 91 mounted on a shaft 98 which is advanced at minute intervals to make five revolutions per hour and to thus bring one of the two lugs 96 of each selector 91 into operative position every six minutes.

The feeding mechanism for the shaft 98 is shown in Fig. 11 and comprises a synchronous motor MI which operates a feed pawl |00 through a mutilated pinion IUI, a segment gear |02, an arm |03, a link |04, and a second arm |05 on which the pawl |00 is mounted. The pawl |00 coacts with a, twelve-tooth ratchet |06 on the shaft 98 and gives said shaft one revolution every twelve minutes, or a half revolution every six minutes. Overfeed is prevented by a stop |01 and reverse movement is prevented by a holding pawl |08.

The motor MI runs continuously at the rate of one revolution per minute, except when rendered inoperative by a program-controlled cut-out to be described. Six two-lug selectors 91 are provided on the sh'aft 98 as shown in Figs. 6 and 15 and these selectors overlie six interponents 95, each of which is associated with a separate punch PI. The shaft 98 is advanced one space at the end of each six-minute interval. and each such advance movement brings the next lug 96 (Fig. 15) into position to hold its associated interponent 95 from rising. The associated punch' P' is thus held in operative lower position in the punch plate 10.

In Fig. 14 I have shown a punch P2 held down by an interponent ||0 engaged by one of the two lugs on a selector ||2, mounted on a shaft III. The shaft |I4 (Fig. 12) is provided with a twenty-tooth ratchet ||5 which is intermittently advanced one space every six minutes or one-tenth of an hour by a. feed pawl I |6. The feed pawl I6 is mounted on a feed lever ||1 actuated by a double cam I8 on the end of the shaft 98 lpreviously described. The shaft 98, as previously stated, makes one revolution every twelve minutes and the double cam ||8 thus operates the feed pawl I I6 every six minutes or each tenth of an hour. The shaft |I4 is thus given a complete revolution once every two hours. Overfeed is prevented by a stop |I9 and backward movement is prevented by a holding pawl |20.

Ten selectors ||2 (Figs. 6 and 14) are mounted on the shaft H4, and spacing plates or collars |22 are interposed between certain selectors. Ten interponents ||0 are provided as shown in Figs. 7 and 14, and each interponent is associated with one of the punches P2 which show tenths of an hour. Where these punches P2 are aligned withl punches -PI (Fig. 5), the corresponding interponents are offset laterally at their ends as shown at ||0a (Fig. 7) to clear an adjacent interponent 95.

In Fig. 16 I have shown one of the punches P3 for hour units being held in lowered or punching position by an interponent |25 engaged by one of the two lugs |26 ona selector |21, which' in turn is mounted on a shaft |28. The shaft |28 has a twenty-tooth ratchet |30 (Fig. 13) and is advanced one step each hour by a feed pawl |3| on a lever |32 pivoted at |33 and actuated by a double cam |34 on the shaft |I4 previously described. The shaft ||4 makes one revolution every two hours and consequently the double cam operates th'e lever |32 and feed pawl |3| once each hour.

The ratchet |30 has twenty teeth, so that the shaft |28 is given a full revolution in twenty hours. Program mechanism to be described holds the selector mechanism inoperative for four hours out of each twenty-four, so that the ratchet |30 and shaft |28 in effect make one revolution during each twenty-four hour period.

A stop |35 prevents overfeed and a holding pawl |31 prevents reverse movement, as in the feeding devices previously described.

Eight selectors |21 (Fig. 6) coact with eight interponents |25 (Fig. '7), and two additional selectors |21@ (Fig. G) coact with offset interponents |25a, (Fig. 7) thus controlling the ten hourunit punches P3.

Two additional selectors |4 (Fig. 6) ccact with interponents |4| (Fig. 7) to control the two h'ourtens punches P4 (Fig. 5). Each of these selectors |40 has a single lug extending approximately one-half of a circumference, so that the zero hour-tens punch P4 is held operative for the first ten hours, and the one punch P4 in the hour-tens column is held operative for the second ten hours of each twenty hour period.

Selector feed control In Fig. 8 I have indicated diagrammatically the control of the selector feed, so that the feed will be operative twenty hours only during each' twenty-four hour period. I have shown a four lobe cam |45 mounted on a shaft |46 which is associated with the clock motor 9| in such manner that the cam |45 makes one revolution each hour. 'Ihe cam thus operates the feed lever |41 once every fifteen minutes, and the lever |41 through a feed pawl |48, ratchet |40, pinion |50 and gear advances a disc |52 tocomplete a full revolution each twenty-four hours, with va fractional advance movement every fifteen minutes.

A lever 53 engages the edge of the disc |52 and normally holds contacts |54 engaged. Cutout portions |55 are provided in the edge of the disc |52 at any desired time intervals. When the end of the lever |53 drops into one of these cut out portions |55, the contacts |54 separate and the driving circuit of the selector motor M (Figs. 8 and 11) is broken, thus holding the selector mechanism stationary until the lever |53 is raised and the contacts |54 are re-engaged. It will be noted, however, that the circuit for the clock-driving motor 9| is not broken, so that the control cam |45 which feeds the program disc |52 is continuously operated. Cut-outs |55 may vary in length from minutes to 4 hours.

The ratchet |53 makes one revolution in siXty minutes and the ratchet |63 makes one revolution in twenty-four hours. The minute typewheel W is geared to rotate once an hour with the ratchet |63, and the hour type-wheel is caused to rotate with the twenty-four hour ratchet |69. The program disc |52 previously described appears in Fig. 1 and is rotated by the mechanism shown in detail in Fig. 8. The cam shaft |46 also supports the twenty-four hour ratchet |69 as stated.

Carriage structure I have already described the six punch units which are provided for the six usual daily registration periods. These punch units occupy xed positions transversely of the machine. The record card is guided for straight-line movement through the machine and with no transverse shift or displacement.

In order that the printed and punched records may occupy predetermined spaces lengthwise of the card, I mount the type-wheels and driving mechanism shown in Fig. 1, the program mechanism shown in Fig. 8, the punch selector mechanism shown in Fig. 6, the interponents shown in Fig. 7, and the platen with its solenoid-operating mechanism shown in Figs. 1 and 3 all on a carriage R (Fig. l) which is supported on fixed guide-rolls |80, two of which are shown in Fig. 1. It will be understood that such additional guiderolls are provided as are necessary for rmly supporting and accurately guiding the carriage transversely of the base.

The transverse shift may be eifected by gears |82 (Fig. 1) engaging rack bars |83 formed on the lower edges of the carriage R. These gears |82 are mounted on a shaft |85 (Fig. 2) driven from a synchronous motor |86 through a periodic shift mechanism |81. This shift mechanism forms no part of my present invention and may be of the general type shown in the prior patent to Watkins and Dell, No. 2,101,205, issued December 7, 1937. Any usual ribbon and ribbonfeed mechanism may be provided for the type wheels W but this also constitutes no part of my invention and is omitted in Fig. 1 for the sake of clearness.

The solenoid coil 61 (Figs. l and 3) for the platen 65 is mounted in a depending frame structure |90 secured to the under side of the carriage R, so that it may move transversely with the type wheels and will remain at all times in vertical alignment therewith.

Summary 'Ihe construction of my improved recorder has been described in detail and it is believed that the general utility and operation has been made clearly apparent.

Briefly summarized, the carriage R shifts automatically at predetermined periods transversely of the path of card travel to bring the type wheels in alignment with the correct column on the card as designated in Fig. 2, and, so that for each working period the type wheels will coact with a selected punch unit to make a printed record of the actual time and a punched record of the decimal time in the right column whenever a card is presented and passed through the machine.

The decimal time, however, will be on a twentyhour basis of actual working time and will automatically eliminate regular non-working periods, so that for computing purposes the punched records may be taken at face value. The usual provision is made for shifting the carriage rearward to receive irregular or extra in and out 9 records in the extra columns on the card shown in Fig. 2.

My improved recorder has the very important advantage of presenting a printed record of actual time for inspection by an employee and a punched record oi decimal time which may be automatically tabulated and computed by machines provided for such purposes.

Having thus described my invention and the advantages thereof, I do not Wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
