1 Claims. (01. 234-43) October 30.- 1928, it being the main object of my invention to apply power by means of a clock controlled power operated device to the shifter instead of relying on a clock movement to supply the power. My novel structure includes means which is adjustable as in a program clock for timing the movements of the tray so that as a desirable end, I may provide for in and out shifting of the card tray for morning, afternoon and mechanism is entirely automatic, there being no hand lever or other device to which the registree must apply manual effort to affect an imprint or registration of the time upon a card. 7

Referring to Figs. 1 and 2, a synchronous electric motor ll, operating through a suitable train of reduction gears indicated at I I, drives the shaft I2. Shaft I2 has at its outer end a gear l2a meshing with gear II to drive the vertical shaft overtime, as distinguished from employing the shifting of the card tray for days of the week and using a card abutment for selecting in'and out registrations for the said three working periods.

Among otherobjects of my invention is the combination with an automatic card tray shift locked against tampering movements of means for rendering the locking function ineffective to the end that a person authorized to do so, may position the card tray irrespective of the automatic device.

The above and other advantages to be noted I accomplish by that novel structure and arrangement of which an example is illustrated in the drawings and will be described.

Refer to the claims that follow this description for a statement of the novelty inherent in said example.

Throughout the drawings I have omitted certain mechanisms whose functions are not essential to an understanding of my present invention.

It. At its upper end the shaft H has a gear a which meshes with gears Ilb and llc to drive the time indicator lid on the clock face. To clarify the drawings the lower portion of shaft H has been broken away but it will be understood that the said shaft may extend downwardly to control the type wheels I! and other mechanism not a part of my present invention.

The shaft M has a gear I. by which the large disc I! is driven in timed relation with the indicator Ila through'gear "a, shaft I621, pinion lie and gear lid. The gear lid and disc l'l are fixed to a shaft lla which is suitably Journaled in the frame.

The disc .I I is provided with slots or openings l8 adapted to receive a series of lugs I! which may be retained therein at desired circumferential intervals by screws I8a having nuts lib.

With the arrangement shown the disc I1 is timed to make one revolution per day. An arm 20 pivoted to the frame at 20a has a downward projecting finger 20b and as the disc I1 revolves the lugs i9, striking projection 20b, lift the arm 20 slowLv upward. As the lugs pass the projection the arm 20 will drop to its normal position and in so doing will each time set into operation my improved mechanism for changing the lateral position of the card tray as will be presently described.

The card tray, indicated at 2|, is slidably mounted on the rods or

shafts

22 and 23 and has depending side members or ways 2la which are channel shaped in cross section and serve to guide the card to a position between the type wheels l5 and the printing hammer 24. An abutment plate 25 slidable in the ways 21a, limits the depth to which the card may be inserted in the tray and thus determines the vertical placement of the imprint on the card. The position of the abutment plate is controlled by a cam 26 which has a follower 280 located on an arm 21, said arm being pivoted to the frame at 210 and having at its other end a rail or bar 21b upon which the stud 25a (extending from the abutment plate 25) rests.

In the machine ill trated the operation of all When a card is. inserted in the tray the abutment plate 25 and arm 21 will be moved slightly downward, due to a lost motion arrangement in corporated in arm 21 but not shown in the drawlngs. The lost motion is utilized to close a switch 28 completing a circuit to a solenoid 29. Solenoid 23 attracts plunger 23a against tension of spring 28b to rock the hammer shaft 23, through link 30 and lever arm 2311 thus actuating hammer 24 and forming an imprint on the card. This arrangement is described and claimed in my copending application Serial No. 219,438, filed July 15, 1938, and forms no part of my present invenarranged to rock the arm 42 which arm carries tion, being merely incidental to a description thereof.

Pivotally attached to the arm 20, a rod 3| is arranged to lift a member 32 being fixed thereto by bracket 3|a. As seen in Fig. 2, the member 32 is slotted at its upper end as at 32c where it is slidably mounted on a stud 32b fixed in the frame. As best seen in Fig. 7 the member 32 is also slotted as at 32c at its lower end where it is guided by a shaft 33 having a ratchet wheel 34 mounted thereon. A pawl 35 for advancing the wheel 34 is pivoted at 35a to themember 32. Mounted beneath the wheel 34 and arranged to be closed thereby is an electrical switch 36, said switch having an insulated contact with the wheel and being supported by a bracket 36a fixed to the bearing standard 33a.

As seen in Fig. 7 the parts .are shown in their normal or inoperative position. As here shown the weight of member 32 and the linkage connected therewith rests upon the wheel 34 by virtue of the block 32d. Backward movement of the wheel is here prevented by a pawl 31 which pawl is mounted by means of bracket 31a to a cam operated lever 38 the purpose of which will be presently described.

As the member 32 and its associated parts are, lifted upward by action of one of the lugs I9 striking the projection b of arm 26, the pawl 35 will be brought into a position suitable for advancing the wheel 34. When the lug l9 passes projection 20b permitting arm 20 and member 32 to drop, the wheel 34 will be advanced to the position seen in Fig. 7a where the tooth 340. has closed the switch 36. At this position of the parts the weight carried by member 32 is imposed upon wheel 34 by the pawl 35 and block 32d and as these members tend to rotate the wheel in opposite directions, it will be temporarily held from rotation. To prevent any tendency of the wheel to spin or travel too far during rotation, a spring member 34b is arranged to bear lightly against the wheel at all times. The

pawls

35 and 31 may be equipped with light springs 35s and 31s respectively to urge engagement with the ratchet teeth.

Closing the switch 36 energizes a motor 39, which motor, operating through a train of reduction gears contained in housing 39a, drives shaft 40 and the cam 4| fixed thereon. The cam -4| depresses lever 38 against tension of spring 38a and the motor continues to run until cam 4| has made a complete revolution and its high point 4|a has passed the follower or roller 38b at which time the spring 38a will return lever 38 to the position shown. The pawl 31, being carried downward with lever 38,wi1l engage beneath the tooth 34c of the wheel and upon the upward movement or return of arm 38 will carry the wheel 34 to its normal position as in Fig. '7 permitting the switch 36 to open and stopping motor 33. Y

a pawl 43 adapted to engage and advance a' ratchet wheel 44, said wheel being moved one tooth at each operation of the arm. Fixed to rotate with the ratchet wheel a barrel cam 45 engages a pin or stud 46 to move the lever arm 41 by a mechanism to be described. The cam track is arranged to move lever 41 to the'right (Fig. 1), against tension of spring 48, as the cam is advanced. After the lever has reached its extreme right'hand position further rotation of the cam will bring into position a cross-track in the cam permitting the sprlng 48 to return the lever to its extreme left hand or starting'position.

Pivoted to the upper end of lever 41, a link 49 is attached at its other end to the card tray 2| so that movement of the lever will result'in pro- 1 portionate movement of the card tray.

Referring now to Fig. 2 the lever 38 is pivoted 7 From the foregoing it will be apparent that the function of each lug |9 on disc I1, is to set into operation a train of mechanism to change the position of the card tra'y.

The barrel cam ,45 and its appurtenances as above briefly described is fully described and claimed in the'Patent No. 1,689,905 issued to James W.'Yates, October 30, 1928, and its detailed construction forms no part of my present invention.

It is desirable to provide means whereby the card tray may be shifted temporarily to any position desired, regardless of the position of the barrel cam. The arrangement which I have conceived to accomplish this object is one of the features of my invention.

In my improved device the lever 41 is mounted at its lower end on a shaft 50 being free to turn thereon and retained in position by collars 5| and 52 as seen in Fig. 2. Fixed in the lever 41 a stud 53 having a large head retains a second lever 54 which is slotted as at 54a to permit a sliding relation between the two levers. Near the lower end of lever 41 a second stud 55 fixed therein engages the slotted portion 54b of lever 54 and serves to guide same in proper alignment. A tension spring 56 fixed at one end to lever 41 and at its other end to lever 54 urges the levers to the relative position as seen in Figs. 1 and 8. The stud or roller 46 which engages the barrel cam is fixed to a short upstanding arm 51 which arm may be fixed to shaft 50 and has a rearward extending pin or stud 58 which stud is of sumcient-length to be engaged by the straight slotted portion 54b of lever 54. Lever 54 has an enlarged opening 540 communicating with the slotted portion 54b already mentioned.

With the position of

levers

41 and 54 as seen in Figs. 1 and 8 the card tray will be locked against any manual effort to shift it from its normal position as determined by the barrel cam. This is due to the locking effect of the pin 58 engaging slot 5417 thereby forming a rigid connection or relationship between the levers 51 tending forwardly. Cooperating with this stud a lever 60 pivoted at 6| on the frame has a forward bent portion 62. On the casing or cover 63 is a cylinder lock 64 having fixed at its inner end an arm 65 having roller 66. As seen the roller 66 is arranged to bear on the lever 60 so that if a key is inserted in the lock and turned clockwise the

levers

60 and 54 will be depressed as in Fig. 9, thereby releasing the card tray from its normal position due to the barrel cam.

An indicator arm or needle 61 is carried by the card tray being visible through a window 66 in the casing. The columnar position of the card tray is indicated by the position of the needle against an index card 69.

In the machine illustrated the cam 26 is advanced a step forward each day (by mechanism not shown or pertaining to my present invention) thus the week-day upon which the impression is made will determine the vertical placement of the imprint on the card. The columnar placement will indicate the in" and out" registrations and it will be apparent that any number of said registrations may be obtained by redesigning the barrel cam and employing a corresponding number of the lugs IS on disc ll. Thus the barrel cam could be made longer and the helical track modified in pitch.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. In a time recorder a card tray, a transmission element forming part of means for moving the card tray laterally which element is self locking'and linkage between said self locking element and the card tray which linkage is normally rigid but is susceptible to operator controlled movement to permit of yielding thereof.
