SPECIFICATION forming part of Letters Patent No. 592,880, dated November 2, 1897.

Application filed. March 18, 1895. Serial No. 542,246. (No model.)

To aZZ whom it may concern:

Be it known that I, ABRAHAM NEWMAN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new Improvements in Tin1e-Recorders, of which the following is a specification.

In the accompanying drawings, Figure 1 is a transverse section of the machine. Figs. 2 and 3 are vertical longitudinal sections of the right and left hand ends, respectively, of the machine. Figs. 4 and 5 are plans of Figs. 3 and 4, the cover being removed. Fig. 6 is an elevation of part of the front cover, looking in the direction of the arrow Z, Fig. 1. Fig. 7 is an enlarged detail showing the mechanism for lateral feed. Fig. 8 is a section on lines X X of Figs. 3 and 5. Fig. 9 is the record-sheet as ruled by the machine, and Fig. 10 is an end elevation showing the relation of the clock to the case.

On the top 2 of the case 1 is a rectangular frame or shallow box composed of front and

rear pieces

3 and 4 and

end pieces

5 and 6. Hinged on the rear piece 4 is a box-like cover 7, that has an inclined front 8. Secured to the top 2 are three

standards

9, 10, and 11, that support the shaft 12 and the drum 13. The end of the shaft 12 that is supported in the standard 9 is provided with rack-teeth 14, that are out around the entire circumference of the shaft, so as to permit it to revolve while engaged by the pinion 15, that forms part of the shaft 16, held in an upper and transverse bearing 17 on the standard 9. Secured to the front end of the shaft 16 is a handwheel 18, and on the rear end of the same shaft is a ratchet-wheel 19, that cooperates with the

pawls

20 and 21 on the plate 22, that is pivoted to the standard 9 by the pin 23. A spring 24 serves to keep the pawl 20 in and the pawl 21 out of engagement with the ratchet-wheel 19. Loosely mounted on the shaft 12 are two

disks

25 and 26, that support the paper-carrying cylinder 27. Adjacent to the disk or head 25 is a sleeve 28, that is free to move axially on the shaft 12, but is prevented from rotating thereon by the feather 29, and adjacent to the sleeve 28 is a second sleeve 30, one end of which bears against the standard 9 and the other end of which telescopes into the sleeve 28. The

sleeves

28 and 30 are recessed somewhat larger than the shaft 12, so as to provide aspace for the spring 31, that serves to force the sleeves apart. In the left-hand end of the sleeve 28 is a dowelpin 32, that enters a corresponding hole in the head 25, so as to cause the cylinder 27 to turn with the shaft 12. The other end of the sleeve 28 extends into the form of a flange 33, that is somewhat larger in diameter than the cylinder 27 and serves as a means of freeing the connection between the head 25 and the sleeve 28 by moving the latter to the right by hand. In the flange 33 is a dowel-pin 34, that passes through a hole in the flange 35 on the sleeve 30, thereby causing the two sleeves to revolve in unison. On the flange 35 is a lug or cam 36, that cooperates with a similar lug 37 on the plate 22 to move the said plate to the right once during each revolution to release the pawl 20 and cause the engagement of the pawl 21. As soon as the cam 36 has passed the lug 37 the spring 24 returns the pawls again to their original position.

The cylinder 27 is prevented from axial movement on the shaft 12 by placing the head 26 between the collar 38 and the shoulder 28, which is formed by turning that end of the shaft to a smaller diameter. Supported partly by the standard 11 and partly by the end of the shaft 12 is a drum 13, one flange of which is formedinto a ratchet-wheel 40, that engages a pawl 41 on the gear 42, which latter is mounted upon the shaft 12 and secured thereto by a feather. This construction permits the shaft to move axially, but prevents it from turning except as the gear turns. The end of the hub on the drum 13 that projects beyond the standard 11 is formed into a square 43 for the application of a key to wind up the weight connected to the cord 44 on the drum 13. Also supported in the

standards

9, 10, and 11 is a long shaft 45, on which is a gear 46, that meshes with the gear 42.. The shaft 45 extends beyond the

end pieces

5 and 6 and has one end connected to the gearing of an ordinary clock, by which means the cylinder 27 is restrained to turn only once in twelve hours or such other time as may be desirable. The other end of the shaft 45 may be connected to mechanism that will move hands over a dial in unison with the hands of the clock at the first-mentioned end.

Secured in the upper part of the cover 7 is a metallic frame 17, that support-s a shaft 48, on which are a number of thin metallic levers 49, that work in slots 50 in the frame 47. Each lever it carries a point 51 and a weight 52, that serves to keep said point in contact with the cylinder 27, or, rather, the paper carried by said cylinder. The ends of the levers 49 opposite to the weights 52 project through the face 8 of the cover 7 to a point under a series of eccentrics 53, that are mounted on the shaft 54, that is supported at the ends by boxes 55. Each eccentric 53 is provided with a rod 56 and a disk 57, which latter are numbered successively to represent the numbers by which the employees are designated. The rods 56 are of such length as will arrange the disks or keys 57 in banks for the purpose of getting a greater number of eccentrics in a small space without m akin g the disks smaller than is practicable. It will be obvious that when an eccentric is in the position shown.

in Fig. 1 the point 51 of the corresponding lever 49 will be in contact with the face of the cylinder 27, but that when a key (as the one marked 3 in Fig. (3) is moved to its lower position the connected eccentric is turned on the shaft 51 and acts upon the corresponding lever 19 to raise the point 51 from the cylinder 27.

The record-sheetis divided by verticallines A, the distance between which is exactly equal to the distance between the points 51 on the levers 4-9. The spaces between the lines A are numbered to correspond with the numbers on the disks 57, and in these spaces the weeks record of the employees is kept. The sheet is also cross-ruled by the lines 13 to represent hours and intermediate lines to represent divisions of the hours. On the margin are marked the hours, and the distance between VI and VI is just equal to the circumference of the cylinder 27. The sheet may be secured to the cylinder in any convenient manner that will insure its accurate location, but preferably by means of perforations C, that fit on pins 58 in the cylinder 27. The length of the sheet greater than is necessary to encircle the cylinder simply laps over and is secured to the first end by a sticker that is very well illustrated by a postage stamp. After the recordsheet is wrapped on the cylinder and secured thereto a sheet of carbonpaper is wrapped around the outside and secured in the same manner. The action of the points 51 in pressing upon the carbon-paper as the cylinder 27 revolves produces the lines D on the record-sheet, which lines represent the employees time.

At the right of the bearing in the standard 9 is a plate 59, provided with a set-screw 60, that serves as an adjustable stop for the end of the shaft 12. This stop is so adjusted that when the shaft 12, and consequently the cylindcr 27 and the record-sheet carried thereby, is moved to the extreme right by turning the gear 15 by means of the hand-wheel 18 each one of the points 51 is close to, and just to the right of, the lines A on the record-sheet.

Assuming the parts to be so adjusted. on Monday morning and the cylinder set to correspond with the clock connected to the shalt 45, then the operation will be as follows: .ldat-h employee as he comes in will raise the disk bearing his number from its lower to its up per position,which action will revolve the corresponding eccentric and permit the corresponding point 51 to begin marking on the record-sheet. When he goes out at noon, he will lower the disk, thus raising the point from marking. He will repeat this operation of raising and lowering his number as often as he comes in and goes out, and the consequent ruling will be an accurate record of his time. At some time during the revolution of the cylinder 27, preferably between. the hours of twelve and one, the cam 36 comes into contact with the cam 37 to shift the

pawls

20 and 21, thereby causing an escapement of one tooth of the ratchet-wheel and consequent movement to the left oi the cylinder 27 through the action of the spring 31. The next revolution of the cylinder will therefore cause the line ruled by the point 51 to be adjacent and parallel to the line ruled during the first revolution. As employees are supposed not to be present at night, only every other line will be actually ruled on the paper, and the amount of feed caused by the escapement is just enough to make the six. or seven lines ruled fill slightly less space than. that between the lines A. At the end of the week the sheet is removed and a new one subsliituted and the drum 13 is wound up. The handwheel 18 is also turned to move the cylinder 27 again to the right and wind up the escape. ment.
