My invention relates to worlrmens time recorders and has as its object the provision of means for distinctively printing all over time records, in such a way as to prevent tampering by dishonest workmen.

More specifically it is my object to provide in connection with the time printing means of time recorders for the printing of records during periods of overtime, in a dierent ink for normal records, and furthermore to print a slug alongside of the overtime records.

It( has' been found possible to cheat machines which print overtime records in red ink, by inserting a piece of carbon paper with the time card, so arranged as to block o' the printing ribbon, and give a registration which is sufficiently like normal registrations on the card to avoid detection. Where a slug is printed, however, together with a distinguishing color of ink for the time record, it is not believed possible to obtain a false imprint. It would require that the falsier should employ an impervious insert along with his card to prevent the slug from printing, and a carbon paper as well, to correct the distinguishing color. I have been unable to do both of these things myself and do not believe that it would be even remotely possible to accomplish them.

I attain the objects of my invention by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings:

Fig. 1A is a detail of the ribbon supporting means.

Figure 3 is asimilar view to Figure 2, 'showing the parts when printing an irregular registration.

` Figure 5 is a plan view of a time card with time registrations imprinted thereon.

My time recorder mechanism is no different from that. of any time recorder, except is a side elevation of the said as concerns the provision of means for shifting a printing ribbon during certain periods of time, and at the same time shifting an arm to a positionA alongside of the time wheels, this arm carrying a type face, which will be impressed upon the card.

' In time recorders of the type in use at the present day, the normal structure comprises time wheels rotated by a clock, a platenv in the form of a rubber faced hammer which is energized and tripped so as to fly against the face of a card, a card tray in which a card is held, and a printing ribbon interposed between the time wheels and the card. The time wheels have type upon them for the hours and minutes of the day.

The mechanism for supplyingthe energizing force to the selective devices for shifting the ribbon and raisingthe slug type face to printing position alongside of the time wheels is energized by the manually moved handle that Works the usual platen. The mechanism for controlling the result of the applied force of the manual printing handle is energized by the clock, and in order to I- permit of the handle being depressed fully at times when the clock operated mechanism prevents the operation of the said selective devices, the manual handle is connected to theselective mechanism itself by means of a spring.

The time clock (not shown) drives the vertical shaft 4, being coupled to this shaft by the usual coupling. On the shaft is Va Worm 3 which drives the pinion of a large circular dislr 1. This disk or dial is calibrated for hours and revolves once in 24C hours. It has circumferentially arranged interrupted slots 2 therein. In the slots are lifting lingers 8, held in place by screws, so as to be adjustable in the slots. A lever 6 mounted on a standard 5 of the machine has a depending contact plate or linger 7 which will be engaged by the finger 8, so as to lift and drop the lever as the disk or dial 1 revolves. The raising and dropping of the lever serves to lift and drop a pawl to be described. This pawl rotates the element shift of the machine.

I will first describe the manually operated means which unless inhibited would operate the irregular record distinguishing devices every time the platen handle is manipulated, to eect a printing on a card. A rock shaft 12 is provided for the machine, on which rock shaft is a lever 11, pivotally fulcrumed on the said shaft. Also on the shaft 12 is an arm 13 that is fast thereon and serves to rock the' shaft. The printing platen operating handle 9, in addition to its usual connections, has connected thereto a rod 10 which is pive otally secured to one end of the lever 11. The other end of the lever 11 is connected by a spring 15 with the lever 13, so that when the handle is depressed the shaft 12 will rock unless its rocking is prevented, in'which case the spring` 15 will extend to permit full operation of the printing platen operating handle.

I have merely indicated at 28, the usual printing ribbon retaining element by means of which in many time recorders, the printing ribbon is shifted crosswise to change colors. I have indicated at 24 the usual time printing wheels. I have also indicated a type face 22, termed by me a slug which is to be moved to a position alongside the printing point of the time wheels, during irregular registrations. By my mechanism I have the printing ribbon holder upwardly and shift the type face 22 upwardly, every time the printing handle is depressed unless this motion is prevented by mechanism controlled from the shaft 12.

In order to operate these two devices I provide a rock shaft 19 mounted above and forwardly of the shaft 12. On the shaft 19 is an arm 20, connected to a metal piece 21. This piece has a forked lower end that engages slidably over a rod 23 on which the time wheels are revolubly mounted. One portion of the fork has the type face 22 thereon. When the shaft 19 is rocked the arm 2O is tilted up, the piece 2O lifted, and it slides up as guided by the rod 23, until its type face comes on a line with the printing point. The two positions of the type face are shown in Figures 2 and 3. Y

In order to shift the ribbon I provide a lever 25, that is fulcrumed intermediate its ends on the rod 23. One of its ends engages the ribbon shift device 23. The other end of the lever 25 is pivoted to a link 26, and the link pivoted at its upper end to an arm 27 also on the shaft 19. Thus when the shaft 19 is rocked the link 26 is lifted and the ribbon shift moved up to change the printing surface of the ribbon from one color to another. It is not believed to be necessary to describe the usual two color ribbon and ribbon shift, as every typewriter and many recorders are equipped with them.

The operating devices by means of which the rocking of the shaft 12 will rock the shaft 19 are a hook-shaped plate 16 mounted fast on the shaft 12, a link 17 connected to the free end of the plate 16, and an arm 18 fast on the rock shaft 19, and connected to the link 17.

The inhibiting devices serve to prevent the operation of the shaft 19 by opposing the motion of the plate 16. To accomplish this two disks are provided, as shown at 33 and 41. These disks are coupled togetherV and are mounted over a suitable rod in the machine complish an irregular registration indication .e

by means of printing in an off color and also printing the typeface 22, on an inserted card. When a tooth of the disk 41 is presented to the lug43, the piece 16 cannot rock.

The disk33 is an operating disk, and is revolved by the raising and lowering of the lever 6 by means of the fingers on the dial 1.

lThe lever 6 has a link 30 connected to its outer end, which link is connected to one end of a plate 31, that is pivotally supported on the rod 23. The plate 31 has an overthrow preventing tooth 34 therein that engages in between the teeth of the disk 33. Pivoted at the free end of the plate 31 is a pa wl 32, which follows the edge of the toothed disk 33, being held by gravity 'and with a spring 32% On a stud 36 of the frame is a pawl 37, which has a movement preventing tooth 40 thereon that meshes with the teethof the disk 33. This pawl is kept in position by a :.i;

counterweight 38 secured to its' lower end, while the upper end is urged toward the edge of the disk 33.

Means is provided whereby when the pawl 32 is lifted this not only elevates the tooth 34, :1;

but also will move the pawl 37 so that its tooth 40 rises from mesh with the teeth of the disk 33. This structure comprises a pin 39 on the upper tip of the pawl 37, which pin lies ,in the path of the pawl 32. When the pawl 11:

32 is lifted its end passes above the pin 39. It is then free to be pulled into mesh with a tooth of thedisk 33, and is permitted to fall thereby advancing the disk one tooth in rotation. lower edge of the pawl 32, that in the motion of advance moves between the disk 33 and the said pin 39, thereby lifting it up, and pullingl the tooth 40 out of mesh so that the disk can rotate. its downward movement the lip 33'EL will have moved past the pin 39, so that'the pawl 37 can be pulled back into mesh again by its weight. TWhen the pawl 33 rises again the lip 33a passes over the top of the pin 39, per- 'Ihere is a hook or lip 33u on the lf Vhen the pawl 33 has finished .lid

mitting the disk 33 to be held against movement by the tooth 40 on the pawl 37.

When the fingers 8 lift the lever 6, this raises the connections described and lifts the pawl 32, and when the fingers pass under the plate on the lever 6, the pawl 32 is permitted to fall. Every other time that this lifting and dropping occurs, the plate 16 is permitted to rise sufliciently to move the ribbon holder and shift the slug type face into printing position.

Thus the fingers 8 define by their spacing 'on the dial l alternate irregular record and regular record periods, which can be arranged for any desired periods of the day or night, as per the mechanism described.

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