nun-STAMP.

Be it known that I, CHARLES S. ELLIS, a citizen of the United" States, residing at Chicago, in the county of Cook and State of Illinois, have-invented certainnew and useful Improvements in Time-Stamps, of which the following is a description, reference being had to theaccompanying drawings,

forming a part ()iitlliS specification, in which corresponding letters of reference in the different figures indicate like parts.

The object of my invention is to provide a simple, cheap and compact form of timestamp in which the works of an ordinary watch may be so utilized as to enable the movable stan'iping-dies to be connected to the hour and minute hand arbors at the back of the case.

A further object is to utilize the dial printing die as a shield toprotect the movable dies from injury by enabling them to be normally withdrawn out of the plane of the latter at all times except during the instant of making an impression.

Moreover, it is my purpose to cushion the several parts from shock and especially to (protect the arbors upon which the movable dies are placed, from injurious or positive stress during the operation of stamping.

I accomplish said objects in' the manner hereinafter more particularly described and particularly pointed out in the claims.

In the drawings, Figure 1 is a side eleva- .tion of a device embodying the features of my invention, Fig. 21s a bottom view there of, Fig. 3 is a view in'which the outer case and the annular die are shown in section taken upon the line 3, Fig. 2, viewed in the direction of the arrow there shown, Fig. 4: is a bottom. view showing the back of the watch. case and movable dies, the annular die portion with its yielding frame being removed, Fig. 5 is a bottom view of said annular die portion, and Fig. 6 is a vertical seetional view of the'outer frame taken upon line 6, Fig. 4, the inner or watch case proper,

being shown partly-in central section.

Referring to the drawings, a represents generally a frame portion formed from sheet metal and preferably rectangular in shape having a peripheral depending flange 0 and a flat upper face portion 0, in which is formeda circular bezel (Z, Figs. '1, 3 and 6, for the reception of the usual watch crystal e. The watch case f. Figs. 3, 4 and 6, is in- Sjieeiiicatibn at Letters Patent. amni noa flied Inn's Laos. Serial No. 438,6Q8.

closed within the outer ztiame a, a notch 9, Figs. 1, 2 and t being formed in the latter to receive the usual winding-stem h which projects therefrom. Four studs 2', Figs. 3, 4: and 6 are rigidly attached to the inner face of the plate 0 and depend therefrom. These studs'project'looselythrough perforations in laterally extended brackets which are at.- tached rigidly. to the periphery of the watch, case Shoulders .lc, Fig. 6, are rigidly attached to the studs 2' near their lower ends, and between said shoulders and the brackets j are interposed coiled springs Z, .while like springs m are interposed between "said brackets and the plate This construction not only serves to hold the watch-case faway from the plate 0 but yieldingly suspended beneath the crystal 6 so that the hands may be seen the same asin any watch.

The minute hand arbor n, Fig. (3, is ex,- tended outwardly through the back of the case and has rigidly attached thereto a disk 0, likewise shown in Figs. 2 and 4, to the face oi which is secured a minute hand or stamping die ,0 formed from rubber or.

train at the front of the watch and which are interposed between the hour and minute hand arhors. its a result of the action of said train, the die x is caused to complete its cycle once in twelve hours, while the diep corresponds in its IllOYQll'lGllll to the minutehand of the watch.

Loosely inserted within the casing a, from beneath, is a rectangular sheet metal I casing, generally designated by t, which is provided with a flat bottom portion to having a central opening therein and upwardly extended flanges or side walls a). The latter are provided with vertical slots 211 Fig. 3, through which are loosely projected retain-- ing screws n which are tap ed into the flanges Z), and also pass throng 1 a rigid bail a forming a support for a handle a iio - desired. 15 the day, month and year, may be inserted 45 which might, otherwise occur.

Coiled springs w are placed upon the lower ends of the studs 2' and bear again t the plate u as Well as against the shoulders Zr, thus serving to push the plate u downwardly in the position shown in Figs. 1,

321ml 6, the extent of downward movement being limited by the slots 1).

An annular die ch, Figs. 1, 2, 8, 5 and 6, is formed upon the lower face of the plate 14,

which die is formed from a suitable yield ing material, such, for example as india rubber, and is intended to indicate the hours, ,minutes and such other matter as may be Removable rubber type showing in a suitable'slot 1 The operation of said device is as follows; The stamp is placed in the position shown in Fig. 1 with the annular die 11:, n'eviously inked, resting upon the surface to be stamped. Upon applying a downward pressure to the handle, the annular die, Wltl'l the case 01, is caused to yield against the action of the springs I.I) until its movement with reference to the case a is arrested by the shoulders Zr, which are so placed as to cause said arrest when the tace ot the die to and that of the dies 7') and s are in substantially the same plane: it being understood that said movement. should be sullioient to permit a proper impression to be made by said dies 7) and s. The latter, bein located directly upon the minute-hand arbor, it is of the utmost importance that provision should be made to protect. said arbor from shock or undue stress, not only during the time of n'iaking an impression, but. at all other times. Should the dies 7) and a tend to protrude too far when the 40 movement of the plate u is arrested by the 'plane common to that oi the other dies,

,7 against the springs m, therel'iy yiehftingly maintaining the watch case in a normal po sition. The tact that the annular die :0 is normally held. in a plane below that of the hour and minute marking dies, not only serves to protect the latter from ii'ijurious contact when the device is not in use, but, by its out 'ard moven'ient, tends to prevent the ink from accumulating in the space be tween the annular die and the others and clogging the latter, thereby tending to stop the watch.

By placing the i'noving dies directly upon the minute hand arbor, i am enabled to greatly simplify the construction amt-reduce the cor-5t ol' the device while providing a very small compact. and etlective stamp.

liaving thus described my invention, I claim:

1. ln a. time-stam the crm'ibination oi a watch movement, hour and mimitemarking dies mounted upon the minute hand ar her at the back ot the watch, gears tor connecting said hour n'iarliing die with said minute hand arbor to cause an hourly rotation of said die, a dial stamping die. having hour and minute divisions, and means tor cushioning said lion and minute marking dies upon making an impression.

In a time-stan'ip, the combination ot a watch-movenient, hou r and minute marl in; dies mounted upon the n'iinute-haml arbor at the back of the watch, a dial stampinsi die having hour and minute divisions, said die being free to be moved in and out (ii a.

and. means for cushioning said last. named dies upon n'iakh'ig an ii'npression.

In testimony whereof, l have signed this specification in the presence of two subsrribing witnesses, this 29th day of lviay 1908.

Vv'iti iesses:
