To aZZ whom it may concern Be it known that I,CLINTON E. LARRA- BEE, a citizenof theUnited States, residing at Binghamton, in the county of Broome and State of New 'Yorkfhaveinvented certain new and usefulImprovements in Counters, of which the following lsa full, clear, and

exact description.

This invention is an improvement in apparatus for recording on a suitably prepared card a workmansstarting and stopping time on a given piece of work. Such and to improve the construction of the details which enter into its construction.

The nature of the invention may be most easily gathered from a general statement of its function, and that it resides in av mechanism comprismg a series of tune printed dials with means for operating them by a master or controlling clock so that. thercorrect characters representing time 'L1Il1tS'W1ll,--

be brought-to the printing position, an operative lever, a means for holding a card in proper position, and a means'for printing or impressing on the card in their ap propriate locations the time when such impressions are made. This, in general, is a statement of thenature and purpose of V the machine, but in order that overtime may be recorded in a distinctive color, that the card may be properly notched so as to afford a means of inserting it to the correct amount for each record in the machine, for manually setting the monthand year dials and" for accomplishing other purposes-necessary or desirable in its use, I have devised specialmechanism which may best be understood from the detailed description in the specification which follows:

The invention as above'i-ntimated resides plan view of a part of th g The impression mechanisms Figs. 1 and 2 illustrate most clearly this mechamsm. Transversely across the casing is mounted'a stout shaft 6, carrying a hand lever-7, Fig. 8', by the depressionof which a partial rotation is imparted to the shaft. The sh aftcarries a fiXedarm 01*} plate 8, Fig. 3, extending front and back, at right angles, and to the longer arm of which a spiral spring 9, secured to the casing is attached, serving as one means to maintain the lever 8 in an elevated position.

Mounted on affixed stud 10, carried by a suitable casting secured to the casing is a frame 11, the two sides of which are united by a plate 12 on one side and by a bar 13 underneath, these parts being shown in plan view in Fig. 8. A short arm 14, extending downward from the pivotal end of the lever frame 11, has pivoted to it a rigid bar 15, the free end of which has a rounded step 22 that is normally engaged by a pin 16, in the end of a bell crank lever 17, pivoted on afiiied stud 18, and having its other end 23 rounded and fitting in a socket or circular perforation 19 in the end of the bar 8. A stout spiral spring 20 has one. end connected to the casing or a projection thereon and the other to an extension of the pivotal axis of the bar 15. Finally a spiral spring 21 connectsth'e' bar '15 with the upper wall of the casing. v

If the lever handle 7 be depressed, the" arm 8 on shaft 6 is turned and this lowers the end 23 of the lever 17. The latter engages with a seat in the end of lever 15 by means of the part :16,- and' such movement of lever 17 thus forces lever 15 to the right and slightly downward.

"This forces the short arm 14 over to the right and lowers the lever or frame 11. The long arnr of this lever moves downward more rapidly than lever 15, and hence the bar 13 is brought into engagement with lever 15 and forces it downward out of engagement withthe stud 16.

As soon as this is-done the short arm of frame 11, under the action of spring 20, is

' snapped to the left and carries with it the bar 15, which passes under the stud 16 and is held down thereby until the handle 7 is released and the long arm of lever 17 is raised, when the end of bar 15 again engages the stud 16. As soon as bar 15 and the frame 11 are released the printing is done. When the lever 7 is released, and the parts come to rest, the engagement of the stud 16 with the stepped end of the bar 15 is reestablished through the instrumentality of the spring 21.

' This cycle of operation is taken advantage of to effect the printing or impression of the time on the card. For this purpose a frame 25..is mounted to slide in a guide 26, while its upper portion has elongated perforations through which passes a bar 27, connecting the end portion of the plates of the lever frame 11. At its upper end the frame 25 carries a rubber platen or printing pad 28, which when the lever frame 11 is released and the frame 25 thrown upward strikes the card and forces it against the inking ribbon and the typed characters 011 the time disks.

[n ribbon feed mechanism.

To the shorter arm of the plate 8 is connected a flat bar 29, that extends up through an opening in the top 2 of the base portion of the casing where it is connected, see Fig. 2, with a bar or plate 30, pivoted to a stud 31 secured to the top of the casing. The end of the plate or bar 30 is bifurcated and engages a lever 32 pivoted on a vertical axis carried on the inner side of the plate 30. A springbetween this lever and the plate 30 tends to keep its free end in engagement with the teeth of a ratchet wheel 34:, on the shaft 33, which advances the inking ribbon. *Each downward movement of the operating lever 7 thereon results in raising the short bifurcated end of lever 30 and advances the inking ribbon one step through the engagement of lever 32 with the ratchet 34.

The shaft 33 has at each end a gear wheel 35, which engages with gears 36 on the spindles carrying and imparting rotary feed movements to the ribbon reels 38. The shaft is movable longitudinally in its hearings to bring the gears 35' respectively into engagement withone or the other gears 36, so that the ribbon will be wound up on that reel which is at the moment in gear with the shaft 33.

7 Ribbon reversing 7 In order that the direction of travel of the ribbon may be reversed when it has been 42; The frames-68' carry rollers 43' which by the tension iof springs 41' are heldagainst therolls of ribbon on the reels, and as these latter increase in diameter'the frames are raised and lift-theends of the arms and Pivoted to the frame are: horizontalllevers 45, acted upon by springs 47 connected therewithand to the frame, and pivoted also to the frame are'levers 46, the free ends of which lie between the springs 44 and the ends of the shaft 33. The levers 45 have notches in their upper edges near their ends,

upon the same edges of which beyond the notches projections 48 fixed to theplates 49 carrying springs 44vbear. Finally the ends of levers 46 haveright angled ends 50 which. areadapted to be engaged by the notches in levers 45. The operationI-of'these devices is as follows:

As the'ribbon by the step-by-step movement of the ratchet 34 is wound, say, upon the left hand spool the frame 68 of the latter is raised. At "the same time, the diameter of the other ribbon rollis correspondingly reduced and its'frame is lowered. This results in raising the stop'48 of the plate 49 on the right and lowering the corresponding stop at the other side and thereby depresses the lever 45 on the right out of engagement with the lever 46, but raises'the corresponding lever on the opposite side engaging its lever 46. By this means, when the ribbon roll has increased to a predetermined extent, the pressure of the spring 44 carried thereby forces. the lever 46 on the side of the growing ribbon roll over into engagement with theend of shaft 33 andthrows the gear into engagementwith the sprocket 36 on the other side, as the lever 46 on the latter side is then free to swing, and the direction of the ribbon is immediately reversed and wound upon the reduced spool and off from the other. The shaft 33 has sufficient longitudinal play in its bearings to permit of this.

The time operating mechanism.

The magnet 51 receives an impulse of current once every minute, and hence imparts sixty movements or steps to the minute disk each hour. At all times other than during such movements of the minute wheelv the ratchet wheel 56 is locked bya projection on a spring actuated lever 60, but this lever has an inclined end surface-61' with which the end of pawl 55, see Fig. 9, engages as it descends and is momentarily thrown-out: of engagement thereby with the ratchet 56.

Tmeds'h locking mechanism.

It is moreover important that thetime disks should be absolutely stationary at the instants when the printing is effected: and for this purpose the locking ,mechanism shown in Figs. 2, 9 and '18 is employed.

This comprises a right angle lever 62, pivoted to the side plate of the'instrument and having a lightspiral spring 63 connected therewith. Normally the lower end 64 of this lever rests upon the end of the lever 30,

which, as has been shown, is moved by the operation of the printing lever to advance the ribbon. The pawl which operates the time mechanism has an extension which normally rests upon a right angled end 65 of the lever 54, being held thereon by its spring 66. In the normal condition of the parts the lever 54 plays up and down without hindrance, but should the lever 54 beraised' by the magnet while the printing lever is being operated, the end 64 of the lever 62 by the movement of the lever 30 will be freed, and hence-it will swing over until a notch 67 thereon comes under the bent end 65 of lever 54 and locks the latter in a raised position so that it can not drop and turn the ratchet wheel 56 until the printing lever and lever 30 have been released and restored to normal position. i

Ribbon color changing mechanism.

When cards are printed to show starting and stopping times of a workman the 1mpressions are made by a black ink rlbbon,

but to facilitate computations based on overtime, the mechanism should be so arranged that all overtime may or will be printed in a different color, generally red. The means employed for accomplishing this'is shown in Figs. 3 to 8.

The ribbons reels or spools are carried by a frame 68, which is capable of movement to and fro on the spindles 37. Connected to this frame are two bars 69, the free ends of which are pivotally connected with levers 70 pivoted to the frame. The shaft of these levers has two rigid arms or a bar 71,

secured at right angles thereto, and each arm or end has a stud 72 projecting therefrom which are adapted to be engaged by suitably stepped ends of a swinging lever 73 pivoted to a rigid arm 7 4 on the main operating lever shaft 6. hen the lever 7, therefore, is depressed the lever 7 3 will be raised and'one'end or the other of the lever 71 will be raised according to whether the lever 73 is swung to the left or to the right. By this means the inking ribbon is shifted by bars 69 to present over the printing platen a black portion or a red portion.

The position of the lever 73 is determined by the following devices: A lever 7 5 is pivoted at 76 to a plate 77 secured in the casing 2, and carries a pivoted spring actuated pawl lever 78, which engages with the teeth of a ratchet wheel 79, and whenever the free end of said lever is depressed and released this pawl moves the ratchet 79 one tooth. The ratchet is normally locked by a lever 80, but when the pawl 78 rises it slips over the end of said locking lever and as it descends it forces downward this end and releases the lever from engagement with the ratchet.

Secured rigidly to the ratchet 79 is a toothed wheel 81, and bearing on the periphery of said wheel is a pivoted bell crank lever 82 with a rounded end in contact with the teeth of wheel 81 and a bent end 83 that engages with an elongated slot 84 in the swinging lever 73 and that operates to swing said lever to the left or to the right according as the rounded end is on a raised tooth or in a depression between teeth.

The lever 75 may be operated either manually or automatically to turn the ratchet 79. For example a spring seated rod 85, having a key head 86, may be forced down by hand at the desired time to engage and depress the said lever 75, or an electromagnet 87 energized at the proper time in any suitable manner may, by the movement of its armature, shift a bar 88 which is ivoted to a link 89 connected with lever 5, and thereby raise the lever 75.

The controlling mechanism.

A card may and usually does receive a number of impressions indicating starting and stopping time and other data, and it is obviously necessary that these impressions be received-in their proper place. When the card is put into 'the machine for the first time its corner comes into engagement with an abutment that determines its exact position, but in order that on its second insertion it may move beyond this point to a distance equal to the space for receiving an impression, a cutter 90, Figs. 19 and 21, is pivoted beneath the platform on which the cards lie,and connected by a rod 91 with a projection 92 on the shaft 6, so that each time the shaft is partially rotated the cutter, which is arranged adjacent to the card abutment, will be operated and will cut out a rectangular section of the card at the corner. The next time the card is inserted, it may be. pushed in until the cut away corner comes against the abutment and thus the impression will be properly spaced with reference to the first or preceding iimprcssion. A card with a number of sections thus cut away is shown in Fig. 22, the cut away corner being marked 93.

Time dis/ e setting mechanism. It will be understood from what precedes that the apparatus is provided with a series of disks carrying raised characters indicating units of time, and that these are set by electrical impulses operating through electromagnet 51 to bring directly over the printing pad or platen those units which indicate the exact time of day, month, year, etc. The details of the mechanism employed for this purpose are not of the essence of the invention and may be of any proper character. In that used in this machine, however, certain improvements in detail have been incorporated, and it will, therefore, be described so far as necessary to its understanding.

The minute wheel arbor is designated by 57 that for the hour by 94, for the day by 95, and the month by 96. Other disks to indicate A. M. and P. M., the year or other data may be used, if so desired.

The operation of the ratchet wheel 56 by means of the pawl 55 has been'explained. The gearing connected with the arbor 57 is so proportioned that for every sixty steps of theratchet 56 the ratchet 97 of the hour wheel is moved one step. Similarly twenty four steps of this ratchet produces a movement of one step of the ratchet 98,- and so, on, as may be determined by the special provisions ma'de. Each of the arbors 57, 94. etc., carries a milled head 93, which is used to turn them by hand for purpose of propcrly setting the disks controlled thereby when so desired. The heads 93 have'rigidly attached to them pawls 99 that engage with the teeth of the ratchet wheel 56 and the corresponding ratchets on the other spindles 94 and 95, so that the heads may not be turned backward, but by which the disks carried by the spindles may be adjusted to any desired position by hand.

To transfer motion from one rotary disk to another substantially, the same means are used with the record disk. For example, in Fig. 17, a gear wheel 100 moving with the minute disk and making one complete revolution in an hour has a cam 101 secured thereto, in connection with which is a pivoted lever pawl 102 the end of which bears on the periphery of the cam. Once during each revolution of the gear wheel 100, this pawl drops from the high point of the cam and imparts a partial rotation to a spindle 103, which at its end and in the plane of. the hour ratchet carries a lever 104, Fig. 9, to which is attached a retractable spring 105.

Pivoted to lever 10a is a spring actuated pawl 106, the end of which engages with thehoui ratcliet 97, which, as'the pan/1102 travels upth'e cam 101,;is retracted and on the dropping of "the pawl ,is -released and movesthe-hour ratchet one to'oth. Normally this ratchet is locked ragal-nst' movement by :the 3 engagement-thel'ewith of a pivoted look- -movementisto be transmitted from one disk to another.

In the case of the montlr'or year "disks,

this motion transmitting mechanism is not requ-ired as these. may be more conveniently adjusted-when-necessary by hand. For this purpose there is connected with the disk rigidly a wheel 109, Figs-H12 and 20, with projections 110 on its periphery, which" are normally engaged by a spring actuated lever.

111 on a spindle 112 which is designed to be turned by a key or other means from the outside of the case when necessary to release the wheel, which may then be turned by its milled head 93.

In order that the position of the minute wheel may be at all times visible, one of the train of gears 114, Fig. 13, is on a spindle that carries a pointer 113 over a dial 115, visible from without the instrument and which is marked off in tenths of an hour each having six divisions corresponding to minutes.

This machine is compact, is composed of easily and cheaply constructed parts, and is adapted to perform all of the operations required of such mechanisms in a. thoroughly practicable, efficient satisfactory manner.
