CHARLES MADISON CROOK, OF CHICAGO, ILLINOIS, ASSIGNOR TO. STROMBERG- ELECTRIC COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

v Specification of Letters Patent.

Application filed June 20, 1911. Serial No. 634,304.

T 0 all whom it may concern:

Be it known that 1, CHARLES MADISON CnooK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Card- Elevating Mechanism for TimeRecorders",'of which the following is afull, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to improvements in time-recording devices, such as are used in shops, factories and oflices, for the purpose of keeping a record of the arrival and departure of employees.

This application covers an improvement over the invention disclosed and claimed in vmy application Serial No. 561,152, filed May 12th, 1910, and has for its specific object the provision of electrically operated means I whereby the position of the card within the holder may be shifted periodically, say every twenty-four hours and covering a period of from seven to fourteen days, or, in fact, any desired period.

A further object is the provision of improved adjustable means for holding any sized card in place. i i

These and such other objects as may be hereinafter set forth are illustrated in the represents an enlarged elevation of the cardlifting mechanism; Fig. 1 represents a sectional view on the line 44 of Fig. 5 -look-' ing in the direction indicated by the arrows; Fig. 5 represents a top plan view of Fig. 3; Fig. 6 represents a sectional View on the line 66 of Fig. 3', looking in the direction inclicated by the arrows; Fig. 7 represents a sectional view on the line 77 of Fig. 5 looking in the direction indicated by the arrows; Fig. 8 represents an enlarged sectional view on the line 8-8 of Fig. 5 looking in the direction indicated by the arrows; and Fig. 9 represents a perspective view of the star pinion.

Like numerals of reference indicate like parts in the several figures of the drawings.

In the embodiment illustrated in the accompanying draWing s,.I provide a box or casing 10 adapted to be set against or secured to the Wall, or to a suitable support, against. which the rear 10'is supposed to rest. All of the mechanism is completely inclosed within the" casing where it is secure from molestation or tampering.

Generally described, my invention comprlses means whereby the time card of a workman can be placed face outward within a frame or carrier 11, and the workman, by turning a crank 12, causes suitable impression means positioned in front of the card and operated by the armature 13 of the magnet 14:, to print the desired information on the card. The impression mechanism is pro vided with a plurality of impression wheels adapted to print the minutes, hours or any other information required, and while any suitable mechanism may be utilized, I prefer to use, and have illustrated, the form shown and described in my pendin application Serial No. 466,486, filed Decem' er 8th, 1908. With respect to the auxiliary mechanism employed to print upon the card and to Vary the lateral position, I prefer 'to use and have illustrated the form of-mechanism shown and described in my pending application, Serial No. 561,152, filed May 7 13th, 1910. Hence, so far as the description of these portions of my inventionare concerned,Ihave not considered it necessary or. advisable to- Patented June 1o, 1913..

matter of my present invention which covers electncally actuated means for changing the elevation of the card and improved adjust-- able supporting means for the card itself.

.In order to form a support for my improved mechanism, I provide an angular L- shaped casting A, the back of which, 14;, is

secured to supporting posts or lugs 15 pro jecting inwardly from the rear of the casting. On the end of the back 14: is mounted a supporting plate 16 fastened to the back by means of a pair of screws 16 and atits outer end the plate is supported by a pair of pins or shafts 17, 17, the opposite-ends of which are mounted in the side piece 14 of the casting A. On these pins or shafts are mounted separating sleeves or spreaders 17. On the upper shaft 17 is mounted a central supporting plate 18 and on the lower shaft lf is swingingly mounted a pair of armature plates 19- supporting an armature 20, the magnets 21'of which are secured to ing frame and parallel spindle from the plate 18 by an integral collar or the back 14 in any desired manner, as, for instance, by screw-bolts 22. Y

The day wheel 23 is journale'd on a shaft 24 mounted on the'supporting frame A and bears on its outer face the names of the days of the week (repeated, if intended for a eriod of two weeks use) and having a ratchet wheel 25 rigidly secured at its side through the medium of which the wheel is revolved, as will'be hereinafter set forth.

"Mounted in bearings within the support with the shaft 24 are 'a pair of shafts or spindles 26, 26 in line with each other, one end of the spindle 26 being mounted in the bearing 27 in the frame and passing through and supported by. the plate 18. Rigidly mounted on the 26 is a ratchet wheel 28 separated spreader 29. 7

Loosely mounted on the opposite side of the supporting plate 18 are a pair of locking disks. 30, 30, secured together and to the plate 18 bymeans of pins 31. The disk 30 is provided with a single notch 32 and the disk 30*, which is of slightly. less diameter than the disk 30, is provided with a pair of stops 33 on either side of the notch'32 in the disk 30 and separated from each other by a space equal to the width of the notch 32, the space and notch forming a ratchet wheel forward the dog 53 slides over continuous groove or channel.

Rigidly mounted on the inner end of the spindle 26 is a gear wheel 34, the teeth 35 of which engage the teeth of the day wheel.

'Rigidly mounted on the inner end of the spindle 26 is a inner face of which near its outer periphery projects a pin 40 so placed as to strike the plmon 38 once during its revolution.

late 16.- The On the outer- .face of the plate-l6 is mounts. eda vertical guiding member 42 on which.

is slidably mounted a rack bar 43, the teeth the teeth of oppositely disposed pairs lockingdisk 39 from the t esupporting within which the edges of the guiding bar fit. The downward movement of the rack bar 43 is limited by means of a stop 44 mounted on the bottom of the guiding member 42. A stop or plate 47 is mounted on the upper end of the rear of the guiding bar to prevent the rack bar from sliding off the end in the event that it is thrown out of engagement with the pinion 41.

' Referring now to the means bywhich the several gear wheels are actuated; extending upwardly from the armature support 19, and in fact formed from an extension of one of the supporting sides, is an arm 48 forming with the armature supporting member a bell crank lever wit-h the spindle 17 as a pivot. On the extreme'end of this arm and overthe top of the gear wheel 28 is an actuating dog 49 swingingly mounted on a pivot 50 in the end of the arm. A'spring 51 normally under tension is attached to the actuating dog and the arm for the purpose of'pulling the dog 49 into engagement with the teeth of the ratchet 28 when the arm is swung backwardly by, the movement of the armature. A stop or post 52 is mounted on the frame adjacent the end of the actuating dog and so placed as to be engaged thereby. at the end of the stroke of the dog, serving to prevent an overthrow). A locking dog-53 is mounted on.the post 54' below the actuating dog and held normally against the teeth of the ratchet wheel by'n'ieans of a spring 54. When' the actuatiiig 'dog forces the the end of the tooth against the tension of the spring and is pulled backwardly by the spring to engage the next tooth and thus lock the wheel in place. The lever 48 also has a comparatively heavy spring 55 secured thereto and to a post 56 on the frame, the spring normally tending to hold the armature out of engagement with the magnet 21. It is evident, therefore, that as the magnet is energized periodically the lower arm of the bell crank lever'or armature support, is

raising the arm 48 against pulled forwardly,

55 and pulling the the tension of the spring actuating dog over-a tooth. As the magnet becomes deenergized the spring 55p'ulls the arm forwardly and forces theratehetfahead one tooth. The gear wheel 34 on the opposite side of [the supponting frame 18 being rigidly mounted on the shaft or spindle 26 also revolves with the ratchet 28, carrying with it the star pinion 37 which slides over the outer periphery of the disks 30, 30 By referring to the perspective view of the star pinion, as shown in Fig. 9 and also in'Fig. 10, it will be noted that as the disks 30, 30

revolve the opposite faces of two adjacent full teeth 37*, 37 slide on the outer periphery oflthe' disk 30, and the intermediate half tooth 37 being carried overthe outer periphery of the disk 30*. WVhen, during the course of the revolution of the gear 34, the

half tooth 37 strikes the projecting lug 33 on the disk 3O the full tooth is in position to enter the notch 32 in the disk 30 and the corresponding space between the lugs 33 on the disk .30 and as the gear 34 advances another notch the star pinion is revolved one notch, turning out of engagement with the pin, and again commences to travel over the outer periphery of the disk. As heretofore explained, on the opposite end of the short spindle 36, on which the star pinion is mounted, is also 'mounted a pinion 38 adapted to engage the stop 40 on the disk 39 journaled on the shaft 26 and on the end of which is mounted the rack-engaging pinion 4:1. It is, therefore, evident that so long as the pinion 38 is engaged by the stop 40 the continued revolution of the gear 34: will revolve the pinion tl, raising the rack 43 within the guide 42. The card-engaging mechanism is adjustably mounted on the upper end of the rack, as will be fully. explained later, and consequently, as the rack is raised, the card is raised a corresponding distance. When, however, the rack has reached its upward limit of movement the. star pinion is in position to enter the notch 32 in the disk and at the next actuation is revolved, at. the same time turning the pinion 3 8'one notch and releasing the stop 40.' As soonasthe stop a0'is released the rack I and card-holding means, by reason of its own weight, slides downwardly along the guide in position to be again raised when the stop is again brought'into engagement with the pinion 38. By adjusting the number of teeth of the various wheels and the position of the stop the mechanism may be set for any number of days required. In the machine illustrated, the card-raising mechanism is arranged to be actuated once in twenty-four hours; hence, while the im pression mechanism and the ink-ribbon mechanism moves every minute, the only movement of the card-elevating means takes place once in twenty-four hours, when the card is raised a sufficient distance to permit the printing, indicating the time, to occupy a line higher than formerly.

Referring now to the specific mechanism for holding the card in position to be raised, this is best shown in 'Figs. 3, 5 and 6. A supporting plate 57 is secured to the top of the rack 43, preferably by having a portion of its center punched out, forming an ear 58, turned at right angles to the plate and secured to the top of the rack. A stop 59, preferably formed integral with the plate, in the shape of a turned over lug or car, is also provided in order'to keep the sliding memberfiO from passing out of engagement with the plate. A similar stop illustrated in cific mechanism employed.

supporting plate 57, thus permitting the card rest to slide along the entire length of the plate 57.

It will thus be seen that I have devised a simple and inexpensive means for holding the card in place and at the same time made the actual holding means laterally movable in order to accommodate cards of different widths.

II have thus fully described my invention so far as I consider'it necessary with relation to the specific subject-matter to be claimed and do not limit myself to the spe- Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
