SPECIFICATION forming part of Letters Patent No. 653,669, dated July 1v, 1906.

Application nea August 5. 1899'.

To all whom it may concern,.-

Be it known that we, PETER G. GIROUD, residing at Newark, in the county ef Essex and State of New Jersey, and JAMES S. MAOCOY and WILLIAM B. STAMBAUGII,re-sidn`g at New York city, in the State of New York, all citizens of the United States, have invented certain new and useful Improvements in Time! Stamps, of which the following is a full, clear,

Io and exact description, reference being had to the accompanying drawings,in which like figures of reference indicate corresponding parts.

' Our invention relates particularly to de-v vices such as are illustrated in Letters Patent granted to Charles Stahlberg, No. 424,369. Such devices have been found to be particularly useful in registeringthe amount of time usefully employed by workmen, and to this 2o end each employee is provided with a card suitably spaced or arranged, which is to be stamped with the time when the man arrives at his work on each day and again when he leaves, such card covering any desired pe- Nod-as, for example, a week.

One difficulty with the devices heretofore in use is that the workmen, throu'gh ignorance or carelessness, stamp the cards in wrongplaces. This is due either to the complexity 3o of the gages or other devices by which the proper space upon the card is brought to the printing-slit or to the inability of the em-V ployees to read the directions usually placed upon the back of the card for properly alining or placing it for printing. There have also been serious objections to the power transmitting and actuating devices heretofore employed for the type-wheels in that although they are capable of exact adjustment, 4o still on account of theirdelicate construction they are liable to be thrown out of proper relation during the hard usage to which the in strument must necessarily be put, and the accurate serial movement of the train of typewheels is-often lost'in practical operation. Our invention is designed particularlyto overcomethese and other objectionable features Serial No. 726,249. (No model.)

and defects, as will be pointed out, and by it we produce a device which may be manufactured cheaply and at the same time is of neat 5o appearance, runs with little power, and is accurate.

In the drawings, Figure 1 is a front elevation of our time-stamp, some of the internal 4mechanism being shown in dotted lines. Fig. 55 2 is a top plan of Fig. l with the plunger cut away and showing, mostly in dotted lines, part of the actuating and recording mechan\ ism. Fig. 3 isan end view of Fig. 1, mostly in section. Fig. 4 is a detail ofthe actuat- 6o ing mechanism of the minute and hour wheels. Fig. 5 is a top plan of the ytype-wheels, showing their connection with the main motorshaft. Fig. 6 is a detail of the card cutter or adjuster. Fig. 7 shows, partly broken away, 65 the preferred form of time-card.

We prefer to make the case l of a substantially-rectangular form in section, although that is not material. In the front of the case 1 is inserted the clock-face-2. The top 3, 7o which may extend,'as illustrated, beyond the case onV each sided, is preferably made removable, it being heldin place by hinges, screws, or other suitable means. Attached to the A back of the case isan arm or bracket 4E, which 75 curves forward over the top of the case, supporting at its front end the plunger 5, which carries the platen 6. Directly beneath the plunger 5 and in theline of movement of the platen 6 is an opening or printing-slit 7 in the 8o top 3 of the casing. The type-wheels 8 9 10 1l 12 13 are so situated as to register with the printing-opening 7. (See Fig. 2.) Across the top of the type-wheels and under the cover 3 is stretched an inking-ribbon 14, (shown in 85 dotted lines in Figs. 1 and 2,) which is wound upon and unwound from the spools 15.V Upon the top 3 of the stamp there'is a shoulder 16, which is removably secured by screws 17. This shoulder preferably has an offset, as 9o shown at 18 in Figs. 2 and 6, the purpose of which will be explained.

Attached to and operated by the plunger 5 is an arm 19, bent upwardly and inwardly and having ends bifurcated, so as to slide upon the stem 2O of the punch 21, which is set in the block 22, which in turn is mounted upon the shoulder 16. At each end of the stem 2O of the punch is a button or stop 24. By this means freedom of adjustment between the plunger 5 and the punch 21 is secured, the punch being pressed down or withdrawn only when the bifurcated arm 19 contacts with one of the stops 24. The punch 21 registers with a hole or die 23, which is set in the cover 3 of the machine at the end of and in line with the offset 18. The operation of this part of the mechanism is as follows: A card, such as is shown in Fig. 7, is laid face down upon the cover 3 of the stamp. so that the notch or cut 25 (if a notch have been made already in the card; if not, then so that the upper end of the card) abuts against the shoulder 1S. The plunger 5 is then pushed down. This both operates the platen 6 to press the card against the type-wheels at the printing-slit 7 and operates the punch 21 to cut the edge of the card 26, as indicated by the dotted lines in Fig. 7. Other forms of punching devices may be substituted.

An inspection of Fig. 7 will show that the cut 25 is opposite the date which is printed at the same time. In order to print a dat-e immediately below the last one which appears there, the card is again laid face down on the cover 3 and against the .shoulder 16, so that the last cut 25 abnts against the offset 1S. Each cut thus determines the position of the next date upon the card. By this means no other device except the card itself is required to guide the workmen in placing the card for stamping a new date upon it. A chute 27 (shown in dotted lines in Figs. 1 and 3. See also Fig. 2) extends downward to the side of the case 1 for carrying away the bits of card punched out at the die 23.

Looking next at the internal mechanism of the stamp, it will be observed that there are at the back two motors 31 32 (see dotted lines, Fig. 2) for actuating the clock mechanism (not shown) and the type-wheels. The main shaft for driving the type-wheels is 33. Fast upon shaft 33, which carries the minute-hand of the clock, is a gear 34, which meshes with a gear 35 so proportioned and arranged as to travel at the same speed as the minute-hand of the clock. This gear 35 carries the ininute-wheel 8 of the type-printing series. A roller-bearing 37 on the end of a lever 36 travels over the surface of the cam 38, fast upon the shaft of gear 34. This lever 36 is fastened to the saine hub as lever 39. Near the upper end of lever 39 is a short slot 40, which extends obliquely upwardly and inwardly, (see dotted lines, Fig. 4,) in which the pin of the horizontal actuating-pawl 41 is inserted. This actuating pawl or lever 41, pivoted to lever 39, as explained, extends forward over the wheel 65. This gear 65, which has twentyfour teeth, is fast upon the same hub as wheels 9 and l0, which are the hour and meridian Wheels, respectively.

The operation of the mechanism just described is as follows: As the wheel 34 revolves the cam 38, fast upon its shaft, raises the lever 36, thereby rocking the hub 42, and thus retracting the vertical lever 39, which we will call the driving-lever.7 As the lever 39 retract-s it draws back the actuating-pawl 41. During this retraction the tooth 46 on the under side of this pawl strikes against one of the teeth of the gear 65, and this tends to raise the pawl. This tendency is partly overcome by the pressure exerted by the springs 44 and 45, one of which bears on each end of the pawl 41, sufficient upward movement being allowed to lever 41 to let its tooth 46 clear the gear during its retraction. This double pressure upon pawl 41 would produce friction and binding at the joint between it and the lever 39 were it not for the oblique slot 40, in which the uniting-pin works. Thisjointallows the pawl 4l to be retracted until the bearing 37 upon the end of lever 36 falls from the cam 37,when under the tension of spring 47 the shaft 42 and lever 39 are rocked forward. As the upper end of 39 moves forward it pushes horizontal lever 41, the tooth 46 of which en gages a tooth of gear 65, the forward end of 4l at the same time striking and releasing for a moment the locking-lever 4S, which normally restraius gear 65 from moving forward. In this way the level' 41 carries the wheel 40 forward one tooth, when the locking-lever 4S, being released from contact with the end of lever 4l, drops back at once n nder tension of spring 49 and holds wheel 65 from further movement. Thus at each complete revolution of the minute-wheel the hour and meridian wheels 9 and 10, which are fast upon the same shaft as wheel 65, are advanced together one tooth.

In the drawings we have illustrated the tooth or teeth 46 as integral with the actuating-levers 4l, rbc., the friction caused by their bearing upon the type-wheels being taken up or cushioned by the slot-and-socket joint at 40; but it is obvious that we may instead pivot the teeth 46 upon the lever 4l and press thein into engagement with the teeth of gear 65 by superimposed springs. This would allow the use of an ordinary pivot at 40. )Ve have tried such a device; but, although it is operative, we prefer the mechanism illustrated.

As the hour and meridian wheels complete one revolution a roller-bearing 50 upon lever 5 1 rides upon a cam 52, which is fast upon the shaft of gear 65, thereby rocking a shaft upon which is fastened an upright lever 53, to which is attached by a pin and slot, as before, the horizontal actuating-lever 54 for the day-wheel. The action of this mechanism is similar to that for actuating-gear 65, which IOO IIO

has been described. Similar means is employed for pushing the month-Wheel l2 forward one tooth at the end of the revolution of the day-wheel 1l, and suitable means is also provided for actuating the year-wheel one tooth at the end of the revolution of the month-Wheel. Devices for compensating for differences in the length of months are well known in the structures to which our invention relates and may be used with our invention, and we will not describe them.

It should be noted that in the preferred construction which is illustrated all of the actnatingdevers 4l, 54, and 55 are pivoted in the same way to their upright levers 39, tbc., respectively, and that the forward ends of all of them play in slots oropenings in a single cross-piece 43, the springs 45 for their forward ends being fastened to this piece. In like manner the springs 44 for the rear ends of the actuating-levers are all mounted upon a single brace or cross-piece 5b'. By sucha compact arrangement the simplicity, cheapness. and durability of the device are promoted.

It is sometimes desirable to readjust the type-wheels, as when the clock has been allowed to run down, or when it has lost or` gained time and has to be reset. We have devised a simple and effective means of doing this. Looking now at Figs. 3 and 5, it will be observed that at the rear of the main shaft 33 is a dished wheel 57, having a toothed periphery. Opposite to this wheel 57 is an arm 58, carrying at its outer end a pin 59, which normally engages between the teeth of wheel 57. The arm 58, which carries pin 59, is mounted upon and revolves with the shaft 60 of the motor of the machine. Attached to the wheel 57, as by acollar (il upon its hub, is a lever G2, pivoted at U8 and attached to the push-bar 66, which is normally pressed out` wardly by the spring 64. This push-bar 6b' extends out to the face of the clock and is provided with a button 63 at its outer end. When this push-bar is pressed in, it throws the lever 62 over, thereby drawing the dished wheel 57 out of contact with the pin 59. All of the moving mechanism connected with the type-wheels is now free to be moved independently of the motor and clock mechanism and may be turned and adjusted by turning the hands of the clock or upon lifting the cover 3 of the case by turning the type-wheels themselves.

We do not limit ourselves in any Way to the precise devices shown or to the precise combinations in which they are found, for there are many equivalents for what we have shown and described which will occur to anyone skilled in the art; but
