following is a full, clear, concise, and exa-et.v

description, reference beinghad to thenccompari ying drawing, forming a part of this My inventionI relates to time stamps and automatic numbering devices. V

ln many places, such as record rooms, where documentsare recorded, it is necessary to indorse thereon the exact time when the document isfilevd for record, aud also to numerically numlr the documents so tiled.

One of theobuts ot' my invention is the combining' in a single compact stamp, meehnnism for pjrlning'lii'ne and an automatic numbering device. t l 4 .For the purpose of revealing my .inven-y tion, l. have worked out on-.` torni thereof,

which is illustrated in the accompanying drawings, in which the saine rei'crenceY cha-r- -acters are used to designatc'lilre parte in the several figures'. 'y Y The otlier 1iovel features of my linvention -will' appear from the following description 3o of my invention .als illustrated in said drawings, and partirnlarlypointeil ont in theappeniledciaims.

for the motor mechanism adapted to rest upon the table 4.

A central post or rod 9 is adapted lto reciprocate within asuitable bearing or aperture 10 4in the table 4, said rod carrying a downwardy extending portion 11, said por-A tion being ott' set 4to accommodate the relative sizes of the printing mechanism and numbering device, as shown in Fig. 1. suitable supporting plate 12 is provided, said-mechanisms being pivoted to the extended portion ll of the. rod 9, and the downwardly extending end of the support;

ing plate 12. Carried by the supporting` i plate 12 i-s a suitable hand e 13 or actuating the impression mechanisms, sai ing adapted to move the rod 9, and late 12, whenan iin ression is made` coiled spring lll :is isposed about the rod v9, between the table 4. and the'supporting plate 12,v and is adapted to retain the printing mechanism in normal position, the handle 13 being depressed against the power or' the spring 14 when, an impression is made.

A suitable shaft l5 is journaled between one of the downwardly. extending ends of the snpportinv plate 12,a.nd the extended end of the rod5 9, said shaft carrying a plurality oftyp wheels. I

n time stamps having a plurality of type wheels for printing time, it is desirable that the Wheels remain stationary and in position for making an impression, and that .said wheels bemovcd quickly and intermittently to vary the character of the impression adapted to be made thereby, in order to have the said wheels, at all times inl position for handle bemaking the proper impression, and that said employed for accomplishing thi relnt'ie intermittent movement ot' the type wheels, in

a system of cams and ratchet. wheels attached to said type wheels, said ratchet wheels being moved bye serie of pawls, said pawls being actuated by a second series of pawls adapted to ride upon, and follow the contour of said cams. A stationary shaft 16 is pivot-ed between the extended end 11 of the rod i), and the supporting plate 12, said stationary shaft heilig adapted to support Said ratchet actuating and cam riding pawls, said stationary shaft also supporting,

der; the type wheel 18

carrieslhe numeral.J

4, 5, 6, 7, 8, 9, (l, the type wheel 19v '1, 2 3, carries the numerals-1, 2, 3, 4, 5 0, 1` 2, 3, 4,

. '5, O, the type wheel 20 carries he numerals i, 2, 3, 4, 5, 6,' 7, e, 9,10, 11, 1 2, nie typo wheel 2l carries six A. M. characters, 11,1'- ranged consecutively, and six P. M. charac ters, arranged consecutively. T11/Q type wheel 22 carries the

numerals

1, 2, 3. 4 l, 6, 7, 8, 9,

` O, and the type. wheel 23 carries the folle ing blank spaces and numerals, blank 1, 2, 3, blank 1, 2, 3, blank 1, 2, 3.

The type wheel 1S is adapted to print the -nnits column of the minutes and the type wheel 1S) is adapted to print the tens column of the minutes. It will be seen, therefore, that when the type wheel 18 makes one revolution the type wheel 19 Should be moved one notch or to bring the next character upon Said Wheel in to printing position. The type wheel 2() is ada ted to print thehonr, consequently when tie type Wheel 1S) has made a half revolution the type Wheel V2() should be turned to bring the, next character thereon into printi'er position. The type wheel 21. which carries the indications 1\. M. and 'l). M. is moved one notch or to bring,r the next character1 thtreon into printing osltion, when thel type wheel 19 has movedhine revolution, thns )ringing one of the indications A. M. -or one of the iiidications ,1?. lll. into printing position every two hours.4 'The type Wheel 22 is adapted to print the units columny of the day of the month, the said Wheel being adapted to move to brin-g the next .character thereon 4into printing position when the wheel,` 21 has made one revolution, and the wheel 23 which printf@ the tens column ofthe day of the 'monthis moved 'to ,bring the -next character thereon into 'printing position when the wheel 22 is movedone revolution.

The shaft 15 is driven continuously by the` motor mechanism by means of the pinion 7, the idh` pinion 24 carried. by the stationary shaft. 1G and the pinion 25 carried by the shaft- 15. as shown in Fig. 3, Pivoted to the pinion '25 and adapted to rotate with Said pinion is a rain wheel. 21 shown in Fig. Il. A 0am riding finger or pawl 27, is pivoted to the stationary shaft 1(1,said pawl preferably having lwo arms or members adapted to en frage the am wheel 2G npon dian'ietrically opposite sides thereof and to oscillate there on as the cam wheel 26 is :notatedf An capement wheel .28, shown in Fig. is car-- ried by the shaft 15, said escapement wheel having a hollow interior arrangel eoncen trieally with the shaft 15, and preferably having a small-Hat coiled springfl dis posed within said hollow interior-one end. -of'said spring being attached to the eseapement wheel 28, and the other end thereof be ing attached to the shaft 15. U-shaped escapenient lever 30 is adapted to engage the periphery of the escapement Wheel 2S, the arms ,of the lever preferably engaging the wheel on diametrieally opposite sides there of, said escapennant lever being pivoted by .fneans of pins 31 to the cam pawl 27, the movement of the 4escapelnent'lever 8() being controlled by the oscillations of the cam pawl 27. The cam 32 and the type wheel '1.5 are pivobed to the escapement wheel 28.

A cam riding pawl 33 pivoted to the stationary 'Sharif 16 is' 'adapted to 'follow the Cantoni' of the earn 32, said pawl being; herl in engagement therewith' by the small coiled spring 34 preferably held in position by the plateor rod 17. Preferably iiorn'ied inteffral with the cani pawl is a. strip 35 exten( ingr longitudinally 'with thevshaft 15, the free end of said strip being pivoted to Said shaf asshown in 1Wg. 9.

The operation of so much oit-he printing' mechanism as has'been described, is fol lows: The `shaft 15 `is rotated continuously by pinions 7,' 24 and The ea'capement wheel 2S'is held rom rotation by the prong." of the escapement lever 30'.
