woaxmuvs TIME RECORDER.

Application iiled August 1, 1921. Serial No. 488,895.

lo all whom t may concern;

Be it known that I, JUmUs BRENDLE, a citizen ofthe Republic-of Switzerland, residing at Zurich, Switzerland, have invented certain new and useful Improvements in Workmens Time Recorders; and I do hereby declare thefollowing to be a clear, full,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters 0r figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in workmens time recorders and particularl to that kind of recording apparatus in whic the means for actuating type-wheels are automatically thrown in and out of gear to take intoaccount intervals in the working time.

To control and record workmens time by means of record cards on which the time recorded by a clock work is printed apparatus has already7 been proposed for the purpose of rendering,r superfluous a subsequent addition of the ltotal Woking hours and in which a continuous recording of the working time is effected by an actuating wheel (the day-wheel) which is driven by a clock work and which controls the duration ot' the ratchet movement of the typewheels serving to print the time records on record cards. The ratchet movement of the type-wheels `has been effected by the intermediary of an electro-magnetic auxiliary device.V Such devices are dependent on a source of electricity, further they cause a complicated construction and a delicate apparatus.

The present invention has for its object a workmenstime recorder in which theV aotuatiiig wheel driven by a clock work causes an automatic throwing in or out of gear of the means for causing the ratchet movement of the type-wheels. According to the present invention the actuating wheel influences mechanical controlling means which adjust a locking device. Thel locking device may act upon the ratchet means adapted to impart a ratchet movement to said type-wheels and according to the adjustment of said locking device the ratchet means are operative or inoperative. The mechanical controllingr means may comprise two cooperating control levers one of which serving to render operative the locking device for the' ratchet means actuatin the type-wheels and the other control levereing adapted to cut out said locking-,device Two constructional forms of the object of the invention are illustrated by way of example on the accompanying drawings, on which only the vital parts of the recorder serving to indicate the present invention are shown.

Fig. 19 is a drawing of a form of workmans card to be used in the machine.

Referringv to the rst constructional example illustrated in Figs. 110, 1, 2, 3 and 4 denoteiour frame plates rigidly connected to each other. On the barrel-arbor 5 the actuating wheel 6 is fixed and rotated by 13. Upon a rotary movement of the wheel 6 in the direction of the arrow indicated a cam 8 comes into engagement with the con-y trol lever 11 and causes the latter to swing in the direction indicated by the arrow in Fig. 1, whereby the toothed segment 12 imparts a rotary movement to the pinion 13; the locking device 14 (Fig. 8) which is operatively connected to the pinion 13 by means of a coupling working in onevdirection only and formed by a pawl 13 and ratchet wheel 13 does not take part in said rotary movement of the pinion. The locking device 14 consists of a disc provided with tive stop pins 15 of equal length and of a second disc rigidly connected to the former and provided with three stop pins 16 (Fig. 3), two of which are of a greater length than the third of said pins. Upon a cam 8 having passed the control lever 11 the latter is caused to swing back into its initial position by the action of the spring 9. During this movement the locking de vice 14 is turned by the action ot the pinion 13 and pawl 13 and ratchet wheel 13. rThe locking device 14 is secured in this turned position by a plate spring 17 entering into one of the notches provided on the circum ference ot' the one disc of said device. Upon the return movement of the control lever 11 into its initial position a lateral projecting lug 18 (Fig. 9) provided on said lever bears against one of said stop pins 15 and limits thus the rotary movement of said locking device.

19, 20 and 21 are three two-armed levers acting as propelling-pawls to the

ratchet wheels

22, 23 and 24 respectively, said wheels being rigidly connected to

type wheels

25, 26, 27 respectively used for recording the working time, each of the typewheels being provided around its circumference with the figures 0 9, twice in succession. The pawls 19-21 are independently of each other rotatably mounted on a bolt 28 (Fig. 1 the latter being carried in a forked holder 29 swingably mounted about the axle 30 which is `carried in the

shields

2 and 3. A tension spring 31 is operatively connected to each pawl 19-21 and presses the latter against the corresponding ratchet wheel. The tension springs 31 are connected at their other ends to the holder 29. A cross arm 21 of the pawl 21 abuts against the pawl 20. A stop lever 32 cooperates with each pawl 19-21; the three stop levers 32 are mounted on a common bolt 33 and are pressed against the

corresponding ratchet wheel

22, 23 and 24 respectively by the intermediary ot a tension spring 34 provided for each pawl and said stop levers are lifted out of engagement with said ratchet wheels b v the corresponding pawl abutting with its upper end against the facing 32 of the stop lever upon the swinging motion of the holder 29. The two

ratchet wheels

22, 23 are itted with laterally arranged

discs

35 and 36 respectively which are provided with two notches 35l and 36 respectively arranged diametrically opposite to each other and which are influenced by the tooth of the adjacent pawl 2t) and 21 respectively.

A ratchet wheel 37 actuated at certain intervals from the clock-work 7 through the interposition ot' an auxiliary mechanism, imparts at said intervals. tor example every six minutes a swinging motion (in a clockwise direction in Fig. 1) to the holder 29 by the intermediary ot a lever 38 `fixed on the axle 30 which lever is in engagement with the wheel 37 by means ot a laterally projecting pin 38. Upon the completion of said swinging motion the holder 29 returns in its initial position by the. action ot' a tension spring 39 (not shown in Fig. 1). Each swinging movement ot the holder' 29 causes the propelling paivl 19 of the operative ratchet device. to turn the ratchet wheel v22 and thereby the type-wheel 27 by the amount of one unit g the corresponding stop lever 32. after the completion ot said ratchet movement. comes into engagement. with the teeth ot the ratchet wheel 22 and thus secures the type-wheel 27 in its position. When the type-wheel 27 serving for registering the units (in this case one tenth of an hour) has been actuated nine times, then the tooth ot' the paal 20 belonging to the adjacent type-wheel 26 enters into the one notch 35" of the lateral dise 35 of the ratchet wheel 22 so that upon the following swinging motion ot the holder 29 the two pawls 19, 2O become operative, i. e. both typewheels 27, 2G are rotated by one pitch unit, the type-wheel 26 registers the tens (i. e. the hours). Then the type-wheel 26 registering the hours has been actuated nine times the tooth of the pawl 21 enters the notch 36 of the lateral disc 36 ofthe ratchet wheel 23 and is now in an operative 'position with regard to ratchet-wheel 24. On the subsequent swinging motion of the holder 29 the pawl 21 actuates the ratchet wheel 24 and causes thus a turning motion of the type wheel 25 through the extent of one pitclrunit (a hundreds) the pitch-unit of this type wheel corresponds to ten hours.

As long as the ligure 9 ot' the two

type wheels

26 and 27 is not in the position in which it can be impressed on a record card, the laterally projecting arm 21 ot the pawl 21 prevents an engagement of the pawl 21 with the ratchet wheel 24.

rlhe provision of theI ten hours type wheel 25 enables to record the rworking time of for instance tivo weeks provided tbe normal working time per week does not exceed 50 hours. The record-cards (indicated in Fig. 18 in chain-dotted lines) are inserted into a slot (Figs. 17, 18) in a known mannerv and are therein guided to the front of the type wheels for the purpose of having the time record printed on them.

A coloured ribbon 81 is arranged in front of the type wheels and a spring retracted printing lever 82 is freed from a catch on the operating lever 83, upon the latter being de res'sed.

uring the mid-day interval the

typewheels

25, 26, 27 are not actuated as in the meantime the long stop pin 16 has automatically and through the intermediary of the control lever 11 been moved against the

pawls

19, 20, 21 and has caused the latter to perform a turning motion around the bolt 28 whereby inoperative position, i. e. the pawls are now thrown out of engagement with the ratchet wheels 22-24. 4

When now the time for resuming work has come then the control lever 11 glides ofi the cam 8 of the actuating wheel 6 and causes a further turning movement of the locking device 14. The pawls 19-'21 are thereby thrown in gear and the type-wheels 2.5-27 are again subjected to the influence of the pawls 19-21, and are actuated by the latter as long as the ratchet action is maintained. A 3

After the termination of the normal daily working time the short stop pin 16 ot the locking device 14 comes into its Loperative position after the locking device pin 16 prevents the action of the pawl 21 and thereby a step-by-step movement; of the type-wheel 25 recording the hundreds of units. The two

pawls

19, 20 may continue to work during the next 10 hours and may actuate 'the type'-

wheels

27, 26 to indicate hours and tenths of yhours in order to record an eventual over-time, thereafter an operative action of the control lever 11 on the locking device 14 causes the longer step pin 16 to become operative and the three pawls 19-21 to become inoperative in the manner described above. It is evident that the two

type wheels

26 and 27 have the same figure in the printing position after the lapse of the ten hours over-time, as at the end of the normal daily working time. As in the meanwhile an actuating of the type wheel 27 recording the hundreds Vhas been prevented the indication of the type wheels 25-27 upon resun'iing the work the following day is the same as that at the end of the normal daily working' period.

Upon the re-commencement of the working period the locking device 14 is so adjusted bythe wheel 6 that the three

pawls

19, 21 are operative so that the type-wheels they are brought into an vcooperating with the latter.

25--27 record the working time until the operation of the pawls isb interrupted and the latter are thrown out of gear in consequence of an interval in the Working.

In order' to bring into prominence the over-timey on the cards on which the records are printed a circular disc 4() is pro-l `v vided on the apparatus which has a special mark on its circumference for Ainstance a plus-sign. The circular disc 40 is provided with an arm 40 that projects intol the plane of turning of .a projecting part 41 fitted mto the locking device 14 (Fig. 8), a plate spring42 bearing against said arm 40. At the end of the normal daily working time, as soon as the short stop pin 16 of the locking device 14 causes the pawl 2l to be inoperative, a turning motion is imparted to the circular disc 40 by the projecting part 41 to such an extent that the mark, i. e. the plus-sign, is in the position in which it can be recorded or printed on a card. As the locking device 14 is only adjusted again after the ten. hours (the over-time) have passed, the Amark remains during said period in the ,printing position, so that any record printed during said period bears said mark or plus-sign;

in this way the total amount of he overtime can easily be arrived at. Upon the subsequent turning or adjustment of the locking device 14 the circular disc 40 is turned back into its initial position by the action of a plate spring 42 and remainsxin that position until after it is desired of the apparatus to record over-time.

The circular disc 40 provided with the sign for indicatingvthe overetime is rotatably mounted upon a sleeve integral with a type-wheel 43 (Fig. 4) serving to record or print the months. A plate spring 44 'secures the type-Wheel 43, which is turned by hand, in its momentary position. 45 denotes a type-wheel for marking the working days according to their ordinal numbers. The type-Wheel 45 is actuated by the inter mediary of a ratchet wheel 46 and a pawl 47 The pawl 47 has its fulcrum on a four-armed member 49 ('shownin detail in Fig. 15) and is pressed against the ratchet wheel 46 by means of a spring 50. The four-armed member 49 is swingably mounted on a bolt 51 fixed in the frame plate 2, one of its arms 52 projecting into the path of a pin 52 provided on the Wheel 6. Upon each revolution of the wheel 6 the member 49 is turned by the action of said pin 52 and against the action'of a tension spring 53, whereafter said spring causes the member 49 to return into its position of rest. Thereby the pawl 47 shifts the typewheel 56 by the action of a'tension spring 55, j

lll)

the ratchet Wheel 56 being rigidly Iconnected to the ratchet Wheel 46; thus the pawl 54 secures the type-wheel 45 in its momentary position.

The swinging motion of the member 49 causes, through the intermediary of a pawl 57 linked to another arm (the left hand arm in Figs. 1 and 15) of said member, a turning motion of a disc shaped organ 58, on which a ratchet Wheel 60 is provided, against which the pawl 5T is pressed by a plate spring 59. A pin 61 fixed to the member 49 limits the ratchet motion of the pawl 59 by entering a notch of the organ 58. The abutment of the pin 6l against the organ 58 determines at the same time the position of rest of the member 49. The organ 58 is provided with seven notches which correspond to the numbcr of days in a Week; a plate spring 62 is adapted to enter into said notches and secures the organ 58 in its momentary position.

The organ 58, which performs one revolution per Week, is provided at its one side with a guide facing 58 against which a lateral projection on the boss of the control lever 11 is pressed by means of a compression spring 62 (Fig. 2). The organ 58 causes an axial displacement of the control lever 11 relatively to the Wheel 6. Thus the control lever 11 is shifted into the path of a group of cams 8 in dependency upon the day of the Week, at days With the same working time the same group of cams 8 is operative. The highest point of the guide facing of the organ 58 becomes operative 10 hours after the end of the normal Working time on a Saturday, whereby the control lever 11 is brought out of the path of the cams 8, so that the Wheel 6 performs its turning motion Without causing a ratchet motion of the type-wheels 25-27 Whilst on the other hand the type-Wheel 45 With the ordinal numbers of the days is still actuated by the pin 52 and the member 49. On Monday morning, when the normal Working time starts again, the ratchet movement of the type-Wheels S25-2l' sets in again, as in the mean time the highest point of the guide facing 58 of the organ 58 has passed the projection on the boss of the control lever 11, whereby the latter is brought again into the path of the cams 8 and the paivls 19-21 are operative again.

As may be seen from Fig. 1 the outermost point ot' the cam 8 of the Wheel 6 has a greater distance from the center of the Wheel shaft 5 than the remaining cams. This larger cam 8 imparts therefore a swinging motion of a greater magnitude to the control lever 11 and a correspondingly greater turning motion of the locking device 14. The cam 8 serves for example for the adj ustment of the locking device 14 on Saturday, when the normal Working time finishes earlier, for instance at mid-day, than on other days. In this manner the locking device 14 is so adjusted or turned, that instead of the long stop pin 16, which becomes operative on the normal adjustment of the locking device 14, the short stop pin 16 becomes operative and the two

type wheels

27, 26 are then actuated for the purpose of recording an eventual over-time.

The adjustable arrangement of the cams on the wheel 6 enables to bring the moment of their operation in conjunction with the working periods, so that, as the cams may be arranged in several planes, a great variety of operations result. Then a holiday occurs in a Working Week the means for actuating the type-Wheels 25-27 are cut out by hand by moving the control lever 11 so that two longer stop pins 1G are out of operation With the pawls 19-21 and by bringing the control lever 11 into such a position that it is not acted upon b v the cams.

Thus it will be seen that the lockingde vice 14 controlled by lever 11 obtains a clock-wise step-by-step movement from the unidirection coupling device 13', 18".

The extent of this movement of the locking device 14 is dependent upon the distances of the outer ends of the

cams

8, 8 from the centre of the day Wheel.

In Fig. 1 none of the pins 1G of the locking device 14 are in ope-rating position, as all three

pavvls

19, 20 and 21 are free and engage the respective ratchet Wheels, 2Q, 28 and 24 of their

type Wheels

25, 26, 27.

ln Figs. 1 and 3, the short pin 16 is uppermost a-nd in order to complete a rotation the locking device shall make tive steps in accordance With its live peripheral notches successively engaged by spring 17.

The locking device assumes the position shown in Fig. 1 before the noon recess.

By reason of one of the cams 8 coming into action at noon, the long pin 16 at the right of the short pin comes into operative position and all three

pavvls

19, 2O and 21 are moved out of operative relation, so that no time will be registered during this period, At the end of the noon period the locking device 14 is moved another step, releasing all three of the paivls for proceeding with time registration.

The next step occurs at the end of the Work day, and the short pin 16 comes into operation and releases the pawl 21 or the hundred pawl whose movement occurs every ten hours, and the other two pawls 19 and 2O remain operative for a further period of ten hours, so that any over-time may be registered by Wheel 26 for the hours and 27 for one-tenth hours, during which time the -tsign remains in printing position.

At the end of this overtime stretch of ten hours, the locking device makes a fourth step, and all three pawls are Withdrawn L ten hour wheel begins to accumulate and' add on the previous day the hours and fractions of hours of the new. day.

A Workmans card, such as shown in Fig.

' 19 is placed in the machine and stamped at the beginning and end .of the day, if he works by day work, or at the beginning and end of the week.

The card is divided yby horizontal lines A, which aie intersected by other lines to formcolunins B and C, leaving a space at the left and top for such data or notations as may be desired. v

Fon over time he registers in column B each day at the end of the day, and then at the end of the overtime.

Assume the week began 4 Dec. the machine then lis at zero, and he registers at the end' of the week 9 Dec., the difference between the two in column 4C, which is written in by hand opposite the two dates, shows'a 48 hour week. Suppose there is over-time on Dec. 9, then the workman prints the time and. date his overtime begins 9`Dec.485 and also when he finishes 9-l-Dec. 495, and the difference is also written in column C.

The second constructional example of the recorder illustrated in Figs. 11-14 differs from the previously described example in as muchv asthe controlling arrangement influenced by the wheel carrying the cams is provided with two control levers whereas` x only one such'lever has been provided in the @first example; onev of said control levers serving to cut in the .means for stopping the ratchet motion of the type-wheels and the other .to cut out said means.

The wheel carrying the cams' 8, is as in the previous example, fixed to the arbor 5 fof the clock-work and is provided with two rims 6 and 6,`to which are fixed thecams 8; only one such cam on each rim being shown in Figs. 11 and 12. The cams are fixed by means of set screws the heads of which glide in circular grooves yprovided in `loa ed by tension springs 9. The two control levers can' be shited in the axial direction onA thev axle 10i A compression spring 62 mounted on the axle 10 causes the control lever 11 to be pressed in its lateral direction against the organ 58, by which organ the adjustment of the control levers 11 and 11 in the axial direction relatively to the planes of turning of the-cams 'is effected, in correspondence with the day of the week as has been described in the first constructional example.

14 denotes again the locking' device effecting the operative and inoperative position of the lpawls actuatin the type-wheels.

The locking device 14 1s provided with ay toothed segment and an arm 16 carrying 4a locking pin 16. A forked holden 29 swingably mounted on the axle 30 is provided with an axle 28 mounted in the forked ends of said holder, the two-armed actuating lever 17 is turnably arranged on the axle 28. One arm of the actuating lever 17 is provided with a cross-piece 17 on which three y teeth of different height for actuating the three

ratchet wheels

22, 23, 24 are formed.

The ratchet wheels are also rigidly con,

nected to type wheels bearing figures in the manner described hereinbefore; the latter` being not shown in the Figs. 11-13. A tension spring 39 (Fig. 15) operatively conynected to the rear end of the holder 29 .iently to the holder 29. A disc 40 provided with a plus-sign or another mark for. recording over-.timeis arranged and actuated by its arm 40 which cooperates with the forked end of an arm 41, the latter being rigidly connected to the locking device 14. The latter is provided at the opposite side with a double arm 65, 66. To the arm 65 a tension spring 67 is operatively connected whichtends to hold the locking de'- vice 14 in its normal position, in which the arm'66 abuts against a pin 68 (Fig. 1) fixed. in the shield 3.

In the bent'u portion of a stationary plate 69 a pawl 70. is'fulcrumed which cooperates normally with the toothed segment of the locking device 14,- a spring 71 pressing the pawl into engagement. The pavvl 70 is provided inits upper portion with a lpin 72. Onthe control lever 11 a lever 7 3 is rotatably carried which is pressed against a pln 75 of the control lever by a.

spring 74 and is thus secured in its normal position. The control lever 1] carries a pawl 76 which is normally pressed by meansfof a spring 77 (Fig..4) against a pin 7 8 fixed to the'control lever;

In Fig. 1 the lockingdevice 14 is shown in rits inactive position in which it has no influence on the movements ofthe actuating lever 17. The holder 29 is swung by a certain amount at definite intervals, for instance after every six minutes, by means aetuated by the clock work (not shown in ates the ratchet wheel 22 and its corresponding type-wheel recording the units by one pitch-unit, a stop lever (not shown) secures the ratchet wheel 22 in this position until the next ratchet movement is imparted to the latter. The other ratchet wheels and the type wheels connected thereto areoperated and the time recorded in the manner described in the previous example.

The actuating movement of the type wheels is interrupted by the automatically occurring operation of the locking device 14, the latter being effected as follows:

By one of the cams 8 abutting against the control lever11 upon the turning of the wheel 6 in the direction of the arrow indicated in Fig. 1, said control lever 11 is turned so that its pawl 76 is moved in a downward direction and glides` thereby along the toothed segment of the locking device. As soon as the control lever 11 has passed the highest point of the'cam 8 the former is returned into its initial position, by the action of the tension spring 9. 'On this return movement the pawl 76 cooperates with the toothed se ment of the locking device 14 and turns tie latter from the posii tion shown in Fig. 1 into that shown in Fig.

' 2 in which latter position the locking device 14 is secured by the pawl 70. Now the stop pin 16 of the arm 16 contacts with the actuating lever 17 and turns t'he latter so that the teeth of the portion 17 are moved away from the ratchet wheels 22--24. The stop pin 16 against which the actuating levers 17 are pressed by the spring 31 prevents said lever from operating the ratchet wheels, as the toothed part of said lever cannot come into engagement with the ratchet wheels 22-24 when the holder 29 performs its periodic swinging movement.

Upon the further rotary movement of the wheel 6 carrying the cams the cam 8 co-` operating with the second control lever 11 engages with the latter and causes it to be swung out of its normal position so that the lever 73 is moved in a downward direction. During this movement the lever 73 glides past the pin 72 of the pawl 70 and the upper end of said lever is now vertically below said pin. At the end of the working interval the control lever 11 has passed the cam 8 and is returned into its initial position by the action of the tension spring 9. By this return movement the levers 73 impacts against the pin 72 and causes a turning motion ofthe pawl which thereupon disengages the teeth ofthe locking device 14.

In consequence thereof the locking device 14 is turned back into its inactive position (Fig. 1) by the action of the tension spring 67 connected to the double arm G5, 66, in which position the latter bears against the pin 68 and moves the teeth of the actuating

lever

17, 17 into engagement with the ratchet wheels. Upon a small displacement of the pawl 70 the lever 73 glides ofi' the pin 72 and the pawl 7()v is brought again by the action of spring 71 into engagement with the toothed segment of the locking device 14.

The above described motions are repeated as soon as the control levers 11 and 11 are actuated by the cams 8 for the purpose of cutting in and out the locking device 14 and thereby the ratchet movement of the type wheel. The actuating of the two control levers may be etfected one shortly after the other by adjusting the cams in appropriate positions on the wheel 6 or between the actu ating of the two control levers a longer period may elapse and it is thus rendered possible by a single adjustment of said cams to interrupt the ratchet motion imparted to the type wheels for a longer or a shorter period in accordance with the intervals of the working time and to generally adapt the recorder to any conditions given by the actual working time. It will thus be seen that all overtime work may be registered directly on a registering apparatus of the kind described, that is to say without any special manipulation of the mechanism of the apparatus; the driving mechanism of the time type wheels is so mechanically controlled by the cam or stop wheel according to this invention, that after the completion of the normal daily working time, it is first only partially thrown out of operation, so as to be able to register, during a certain interval of time, all overtime work which is indicated by an automatically moved recording character or symbol held in the printing position during this interval of time, after which the ratchet driving mechanism (19* 21) is entirely prevented from performing its driving action until again completely thrown into operation.

All overtime work is separately registered` that isto say, without altering the sum of the working hours registered by the type wheel mechanism at the end of the normal daily working time, as long as the ratchet driving mechanism has not been released for complete action, i. e., the.recommencement of the normal working time.

In order that such a change in the number of hours registered may not take place, during the restricted action of the feed mechanism (over time work) only the type wheel of the units (tenths of hours) and that of the tens (hours) is allowed to feed and that during an interval of time of ten hours, after which these two type wheels have again indicate the number of hours re istered atthe conclusion of the normal dai y working time.
