signor to Telefonaktiebolaget L. M. Ericsson, Stockholm, Sweden, a company of Sweden Application September 12, 1944, Serial No. 553,775 In Sweden September 2, 1943 4 Claims.

The invention relates to an arrangement in time recorders in which the commencement and conclusion of Working time may be recorded on a card, in which. a hole is punched for each recording.

The purpose of the invention is to provide an all-automatic apparatus of said kind which may be used during a longer period of time, for example one month, without any parts of the apparatus having to be manually adjusted. According to the invention this is obtained mainly by a time operated checking device, which moves the cardholder of the apparatus from its initial position one step laterally every twenty-four hours and after a certain number of such displacements releases the card-holder so that it returns to initial position, and in so doing changes the position of the stop limiting the insertion of the card in the holder.

The invention will be described more in detail with reference to annexed drawings. Fig. l is a side view partly in section of the parts of a time recorder embodying the invention. Fig. 2 is similar view, ShOWing some of the details contained in Fig. 1 in another position and the locking device for the handle II omitted. Fig. 3 is a back view of the apparatus, the lever I2I being broken away and the handle I5I removed. Fig. 4 shows the opposed faces of a card and Fig. 5 illustrates corresponding faces of another card. Figs. 1-3 contain exclusively the details of the apparatus which are necessary for a clear understanding of the invention.

Should a card, which has not been punched previously, be inserted in the card-holder I of the apparatus, Fig. 1, its lower portion will act upon a two-legged stop-lever II, fixed to a rotatable shaft I2. In a manner described in my U. S. patent application No. 553,774, filed September 12, 1944, which explains how a card is recorded and punched, the link 2 I, on account of the turning of the stop lever, will lift the pawl 23 so that the handle 21 of the apparatus is released and recording can follow, a hole thereby also being punched in the card. When the card is again inserted in the card-holder, it is stopped by a member for finding the holes (holefinder), as will also be seen from the above-mentioned pat ent application, said finder thereb automatically being introduced in the hole, whereby a succeeding recording will be performed just below the preceding recording. Presuming that the card be punched the first day of a certain month, the first recording will take place in column I, Fig. 4, opposite the uppermost Arrived. The succeeding recording takes place in the same column 0pposite Leave. The next day, the second, the recording will be performed in column 2. This is achieved by the card-holder I automatically being moved laterally by a time-operated displacing device, the operation of which will be described hereinafter.

The card-holder I, Fig. 3, is at the back provided with ears III, II2, which encircle a screw II3, being supported in frame H4. The ear III to the left on the drawing is in the form of a nut. On the screw I I3 rotating, the card-holder therefore will be displaced laterally. During the rotation of the screw a spring I I5a in a spring-box I I5 arranged in known manner at one end of the screw, is tensioned whereby the screw, on being released, automatically is restored to an initial pcsition. At the other end of the screw is a gear pinion IIB, which may be operated by a cogwheel II'I fixed on a shaft II8. Said wheel III, as is seen from the drawing, is not toothed round its entire periphery but has two diametrically opposed recesses, I II, I42. A ratchet wheel H9 is rigidly connected with the cog-wheel. The ratchet wheel coacts with a step pawl I2I and a pawl I22. The step pawl is kept in operating position by a sprin I23 and is turnable around a stud I24 mounted on a feeding lever I21. The pawl I22 is supported on a tap I 26 and acted upon by a spring I25. The wheel II9 steps forward being actuated by said two-legged feeding lever I21 which is supported on shaft H8 and kept in the position shown in Fig. 1 by a spring I28. At its lower extremity the lever I2! is bent to form an angle l3l which projects into a slot I32 in a plate I33 fixed on the frame of the apparatus. Said angular extremity I3I is acted upon, according to the proposed design, by a time-controlled mechanism so that the angular end I3I every twenty-four hours (before a certain hour, for example 12 p. m.) is moved upwardly in the slot 32 until the step pawl I2I on the lever IE1 is moved back and falls into the next tooth groove. After said displacement the angular end I3I is released at 12 p. m. by the clock mechanism, thus permitting the lever I2I to withdraw to its initial position by means of spring I28, whereby the stepwheel I I9 moves forward one step. The wheel I I1 turns the screw H3 over the pinion IIB thereby displacing the card-holder I, Fig. 3, a distance corresponding to a column on the card.

Said displacement is repeated in the same way once every twenty-four hours, when the clock mechanism lifts the angular end I3I in the slot I32. After a certain number of displacements, for example after one week or 8 days, the cog-wheel II! has turned sufficiently to present one of the recesses MI or I42 to the pinion IIS. Under the influence of spring II5 the screw H3 being released in said manner returns the cardholder l to normal position.

At this displacement of the card-holder I to its initial position a new stop position in the cardholder will be formed for card Ii] instead of the stop lever II. Said alteration of the stop position will noW be more closely described. On one side of the cog-wheel II! a cam disk I43, Figs. 1-3, is mounted. When the wheel turns during the feeding operations, a stud M4 is pressed by a lever I 45 against said cam disk. The lever I 45 is fixed to a shaft I46 which, under the influence of a coil-spring I56, Fig. 3, tends to turn counterclockwise Figs. 1 and 2. On the same shaft I46 is another lever l4? which engages a stud I43 on a stop lever I fit. Said lever I6! is supported on a shaft I52 which is fixed at one extremity of an angular link I93 which, at its other extremity, is mounted on the same shaft 12 as the stop arm I I. When the cog-wheel l I! and the cam-disk I43 have turned clockwise to the position shown in Fig. 1, the stud I 35 upon further rotation of said cam-disk moves counter-clockwise to the left, the lever I47 thereby also turning counter-clockwise. The lever I ill moves about the shaft I92 from the position in Fig. 1 to the position shown in Fig. 2. When now the card 59, Fig. 2, is inserted in the card-holder I, its lower edge will touch against the lever E91 which lies somewhat further up than lever ll. Lever BI is now pressed somewhat downwardly, causing link I63 to revolve, whereby the shaft I2 is turned clockwise in the same way as it is turned when lever II is acted upon. Said lever II when turning with the shaft I2 imparts movement to the members I5, I8 and 2i and causes a release of the handle 21. When the card is recorded, the recording will lie somewhat lower on the card than the recording as described previously in column I. The latter recording is intended to be performed in column 9, Fig. 4, opposite the upper Arrived on the card. The columns 9-46 in Fig. 4 may be placed on the same card as columns I-8, but at the opposite face of the card. The horizontal rows for Arrived and Leave in the columns 945 lie, as is seen from Fig. 4, at different distance from the lower edge of the card than corresponding rows in columns I-8. A row in columns 846 then falls between two rows in columns I-B. On account of said difference in spacing from the lower edge of the card a faulty recording of the card would be detected on checking. Thus, should a recording take place in column 2 instead of in column I9, recording will follow between two rows in column 2.

When columns 9-!6 have been employed, the cog-wheel II! has been displaced so far that the succeeding recess I Al or I42 arrives opposite the pinion H6, whereby the card-holder again is restored to initial position. Simultaneously, the stud I44, Fig. 2, is moved clockwise to the inner edge of cam-disk I43, causing the stop II to return to the position shown in Fig. 1.

In order to cause re-adjusting of the cardholder when needed, for example towards the end of a month, the apparatus is provided with a special lever I5I, Fig. l, in the form of a handle, rotatable around the shaft I59. The lever I5I is in normal position moved by a spring I52 against a stop I55. Said handle projects from the casing I53, I54 of the apparatus. If the projecting portion of the handle is pushed down, the lever I21 moves counter-clockwise and the card-holder is displaced one step, as before described. The handle I 5! thereby moves in a slot in casing I 53. To prevent unauthorized interference, the handle I5I is locked as a rule. The handle passes through a hole I62 in a link I6I, which is kept in the position shown in Fig. 1 by the right-hand extremity of the lever I63 which is pivotally mounted at its left end. The lever I63 is kept in the position shown by a stud I6! on a. normally upturned lever I64. When the lever I64 has said position, the handle I5I cannot be operated. Should a locking device, I65, I56 however be acted upon by means of a fitting key, the lever I64 can be turned clockwise into the horizontal position as shown. In such a case the lever I53 can be lowered to the position indicated by a dotted line, thus enabling operation of the handle I5I.

I claim:

1. In a time recorder, a holder for receiving a card, means for moving the card holder stepwise in one direction from an initial position, means for returning the card holder to initial position after a plurality of stepwise movements, a stop for limiting the introduction of the card into said holder, a stop member movable into a position in said holder for arresting the card in a position above the card stop, and a cam actuated by the card moving means for periodically moving said stop member into operative position.

2. A time recorder as claimed in claim 1 provided with a support common to the stop and the stop member.

3. A time recorder as claimed in claim 1 provided with means movably supporting the stop member in operative position whereby said member may be moved a limited distance under the influence of pressure exerted on the card engaged therewith.

4. A time recorder as claimed in claim 1 wherein said holder moving means includes a rotatable feed member engaging and operating said card holder, a pinion on said feed member, a toothed wheel meshing with said pinion and having recesses in which the pinion may freely revolve while said holder is moved by said returning means, a step wheel on said toothed wheel, and a periodically actuated lever for operating said step wheel.
