DATING-STAMP.'

To alliohom "it may concern:

Be it known'that I, ALEXANDER D. JosLiN,

'a 'citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and. useful 1mprovement in Dating'Stamps, ofA which the vfollowing is a speciication.

This invention relates to stub cutting dating stamps, and is an improvement ing ratchets upon the ribbon spools, pawls' for actuating Asaid ratchets adapted to be thrown into and. out of action alternately by reversing disks connected together by a rod working transversely through the heus-- ing-'of the stamp, the disks being locked'in their two positions byaspring pin entering sockets in the side face oi' one of the disks.

-Thedisks each carry a projecting tooth adapted to lift one of the ratchet actuating pawls from its acting position, andwhen the disks are reversed lbyjgiving them a partial turn ontheir axes, they lift one of the pawls out of acti-on andlower the Aother into action. The pawls are supported each upon one of duplicate levers 'arranged transversely of-the mechanismand united together at the center I of, the machine and to a vertical rod de.

pend-iV g from 'and pivotally attachedt'o the Another 'feature of the invention is .a "spring'depressed' pin at the rear of the stamp designed .to hold the. housing when raised and prevent its di'oppin,`g,'arid also adapted to lock the drawer which receives the sevl ered stubs 4when the housing. is shut down,

. the drawer bein lof the stamp an to belocked automatically when the-housingis down.- The date wheel adapted to enter the base locking `keys or I steps or terraces so that they are more-easily operated separately than where all 'are at one level.

portion which contacts with'the wheel date characters projecting slightly below the surrounding pai't which contacts with the slationary or unchanging part of the printing characters, and this center' portion is adapt-- ed to yield vertically, while the surrounding p orton is adapted Ato tip butis otherwise rigi The nature of my improvements, as well as the details of the construction thereof, are more fully set forth below and illustrated' in the accompanying drawings, in which drawings- Figure l is a-longitudinal vertical section of' the stamp. Figs. 2,3 and 4 are sections upon the lines 2 2, 3 3 and 4--4 respectively of Fig. 1. Figs. 5 and 6 are sections upon the lines 5.'5A and G-G respectively of Fig. 3'.

In said drawings, 7, 7 represent the base or Imain trame of the machine, and 8 is a housing carryingthe ribbon spools and pivoted to the main frame by a pivot 9 sothat its forward end can be. raised 'at any time. The platen which makes the impression is carried in the striking arm 10 which is also 4supported upon said pivot 9 and is provided with a knob 11 whereby it may. be struck in giving't-he impression. 'It is also provided with a llifting spring 12adapted to maintain it in the raisedposition. It also carries a knife 13 for' severing the stubs coacting 'with a blade 14 in tliebase of the machine which is by preference constantly impelled toward knife 13 by springs as sent forth in my Patent No. 939,513. The striking arm` is also connected to .the ribbon mechanism by a device'whereby that mechanism is ac- Y tuated at each'operation of the arm, as will be described below. p y

-' The'platen is made in two parts, an outer part l---adapted to Contact with the stationary partof the printing plate; that is the part containing the permanent characters which do ynot need to be 'changedor ad-A j'usted, anda central part 1GA adapted tof make the *impression of the datecharacters. part 15 fitting a correspondingly shaped recess in the head "ieee bei ico `vertical direction independently o the suri rounding part 1.5. It is secured upon a bolt 1S passing through the spherical projec tion l? of the part l5 and into a recess 19 formed in the striker head. Surrounding the bolt 18 is a rubber cushion 20 resting upon the bottom of the recess 19 and confined on the bolt by a nut 2l, Above the central platen 16 is a ,spring 22 surrounding the bolt 1S and confined between the center platen lG and the top of the recess in platen l5 in which said central platen is inserted so that platen 1G may yield slightly in a ver-A tical direction,I und the outer platen 15 can yield to pressure on any of the outer portions of it by reason of the spherical contour of its top b-ut it is otherwise rigid.r These features ofthe platen are adapted to secure even impressions and the central portion is adapted to yield readily in case the type wheelcharacters should happen' to be out of exactalinement, or depressed,or raised above those ot' the surrounding die plate. The bolt 18 serves not only to hold the center platen 1G but also the outer platen as Well. s

The ribbon mechanism is provided )Vith spoolsO arranged one at each side of the printing mechanism and moving the ribbon transversely across the printing devices. T he spools' each carry a ratchet 3l and these ratchets are operated by pawls 32 so as to move the ribbon step by step at each operation of the stamp. rlhe pawls are supported' upon levers 33 which areduplicates of. each other and extend transversely in opposite directions from the center of the machine. Thelevers are united to each other at their meeting ends and are also pivotally united to a vertical bart which is supported by a pin from a depending projection 36 attached to the underside of the strikingl lever 1Q. But one of the pawls '32 operates its ratchet at one time and this is due to the fact that they are controlled as 1 to their operative position as follows Upon the axesof the ratchets 3l and adjacent to 'each of ythem isv a disk. 37. which disks may appropriately be called reversing. disks. Each disk is'providedwith a flange 38, a portion of which is cut and is bent outward so as to form a lifting ringer 39, each adapted to move under'and lift one of the pawls 32.v The disks are connected together by a yoke or bar 40 extending transversely from one to the otherU and 'compelling them to move harmony and to the same extent. An operating handle41 is inserted in the \ange ofone of the disks andl serves as a means of imparting a partial turn tothem.

By cutting away the an'gcs of disks 37 as described, I am enabled to givethe actuatiiig pawls and also the holding pawls 42 which are pivoted to a stationary part of the," c5 housing as shown, accessto theirrespect-ive .Wound on one spool.

ratchets so that the latter can be operated. The lifting fingers 89 not only hold the actu atingpawls out of act-ion, but they also act tu prevent wear upon the points ot' those pawls by rubbing on the uncutportions ot' the ianges during the movements received while they are in their non-acting positions. The uncut portions et' the flanges also support the holding pawls during the periods of non-action. When the disk carrying the handle is operated to reverse' the ribbon, the movement carries a lifting finger under one of the actuating pawls and a portion of the uncut flange under the holding pawl at the same vside of the machine with the actuating pawl and the same movement allows the actuating and the holding pawls at the opposite side of the machine to drop into' acting position on their ratchet. 'In other words, a partial turn of the reversing disks lifts the pawls at one side out of action, and at the same time drops the two pawls at the other side into action. To lock the reversing disks in their two positions I provide a spring pressed pin G0 movable toward one of the disks and two socketsv Gl in the side :tace of the disks adapted to receive said pin. It will be understood that with .each stroke imparted to the press a feeding movement of the ribbon will take` place and the mechanisin described permits avery easy reversal of the feeding mechanism., The advantage ot aA reversible feed such as that shownvisf that it secures an equal. Wear oruse of the ribbon whereas with the usual form of rib bon winding automatically only one Way the passage of the ribbon over the plate and date characters increases in speed as it-,is

Being so easily reversible, I avoid excess of the ribbony on either spool and add greatly to the life of the ribbon besides'securing more uniforml impressions.

Under the hub 43 of the striking arm surrounding the pivot` 9 is located a spring by its spring 45 so that when the striking arm and housing are raised the pin will enter the recess 46' in said hub and lock' the arm and housing inthe raised position. Thepin when not entered in the recess 'also eX- tends 'downward through the base into the drawer space 47 so that in that position it Afor this purpose the drawer top is provided with a downwardly' inclined guide 7'0 at its pressed fpin 4A. This pin is pressed upward i 'extends through an opening in the spring Y "inner 'end as shown, adapted to lift the pin 44 when the' drawer is being closed. At the ,same timethe drawer is'absolutel'y locked against opening without such raising of the arm and housing. The

(printing characters .which are. permanent an do not need to be changed arefojrmedup'on the die plate 50 yand the -date characters are f'formed. upon the wheels 51. These wheels are 'locked in I position by keys 52 hinged at 53 and havin operating devices 54 at their outer ends.

V'arrange these keys 'in'two separate banks or terracessov as to give plenty of room for the ingers of thepoperator in fmaking adjust-z ments of the wheels. Byv thus separating the operating ,ends 54' I avoidwdanger of v'operating more than one key when it is de-V l sired to operate onlyyone. The date wheels are all mounted' upon 'a shaft 55 driven by a train -`of three pim'ons 56, 57 and'58 the'latter'upon an adjusting shaft 5 9. This gear-- ing is located atthe outside of the base but it is almost entirely 'covered by the housing when the-latter' is down.' .The adjusting" shaft as will be noticed is located below the housing-and this permits rme to give the ribbon spools a large amount of room.

I show at'z an adjustable gage against which :the forwaid edge' of the stub of the ticket may be positioned preparatory to the stampingand severing operation. This gage is located within the housing and isenytirelyv concealed from View when the machine is in operative' position. It consists of 'a plate 62 with a turnedfup forward edge and a slotted 'extension extending rear- Wardly,the limbs of the extension passing at opposite sidesof the member 34 and. receving between. them the attaching screw '63 which is entered in the .under surface of the housing. The turned up front edge of lthe gage extends into close Contact with an outstanding roof 64 formed in one piece with the housing and located in a plane above that of the incoming ticket and extending forward to the knife. The gage is an en` tirely separate device, and adjustable without regard to said roof but itis adapted to Vintercept without fail any ticket 'inserted above the printing mechanism.
