BENJAMIN 1 mm m FRANK n. LAUGHLIN, on Kansas em, mrssounr,

- Be it knownthat W,.BE-NJAMIN Hans and 'FRANK D. LAUenmN, citizens of the. United States, residingat Kansas City, inthe county of Jackson and State-of Missouri,

have invented certain new and useful Improvements in -Printer-Tables tor Registers 'and'the-like; and we do declare the, follow ing to be "a fu]l,-clear, and exact description of the inventiomsuch as will enable others skilledr in the art to which it appertains to make and use the same, referencebein'g had tothe accompanying drawings, and' to the letters and figures of reference marked thereon, which form apartof this specification. 1

.Our invention relatesvto printer tables for "register or like machines, and particularly for machines' of the type shown in our apphcationfor, patent for accounting machine,

filed August 7th, 1916, Serial No. 113,656, or

which this application is a division.

. In machlnesof the character-stated, com- 'prising register and printing mechanisms,

type-for printing the entries made in the machine must be carried in substantial prOximity to the operating parts in order to form a compact machine, and consequently the paperstrip and-the inked ribbon, with their operating parts, forming the printer unit must be located so close to the mainportions of the machine thatit isinconvenient to remove the strip-afterthe record is made, or read the strip prior to its removaL' In machines of this characterthe printer unit is also usually assembled with the other operating mechanism within a closed case, in order to prevent access to the record-and operating parts by unauthorized persons.

- It is the object of the presentinvention' to provide a separate printer unit which may be assembled in properrelation'to the type and operating mechanisms, but capable of easy removal-to a pogitiongr 'vhere therecord can be conveniently anda usedportion of the strip removed", the-invent n hat of the larly contemplating the printer unit within the maimase and its swinging-travel through a door opening to expose the record strip for observation and? removal, of the used portion of the strip.

In accomplishing the above other oh I jects of the invention, we have provided im- YASSIGNOBS ro nuromarrc nooxxnnrmo REGISTER column, I cI'rY, nrssoum, aconronarron or DELAWARE.

Referring more in detail to the drawings, by numerals corresponding to thoseusedfor likepartsinthe parent case: o

. 1 designates a case within which the reg- Pivotally mounted on said pin 98 is one .end

of-an elbow lever 100, theother end-of which is pivotally mounted on, a pin 101that con nects the free end of the arm 102 keyedion the control shaft 43. Also keyed on the ycontrol shaft ar'e levers 105, which control Fig. v11 i a detailelevation of the the selecting bars 70, wher'ebypositioninf of the registerand type carriers is efiec'te .I- have also illustrated the type sectors 111, wh1chare carried on arms 109' pivoted on studs 110 carried by the machine frame and having pinand slot connection 129 -130 i with the selecting bars 70, whereby the type the.present description, as reference maybe .made to the parent case for full descrlptlon sectors are moved to and from functional position upon movement of the bars.

Hammers 142, set'table from the mam crank shaft 21 and throwable by the spring 193, serve to strike the type in the sectors to efieet printing at a proper period in the operation ofthe main machine.

We have limited description of the parts in the main machineto avoid prolixity in of the construction and operation of such parts. Attention is, however, called to the fact that there is no fixed connection between the main. operating and printing parts that would interfere with the free movement of the table as presently, de-

scribed.

Mounted on and extending inwardly from-the side wall of the case 1, adjacent one edgeof the door opening, is a boss 570 and mounted on said boss and on the bottom of thecase are facing pins 569, having point bearings engaging built up bosses 568 on an arm 567 ,of the table 18 forming unit.

Mounted in the front end of the table are spacedframe plates 572 573-and rotatably the supporting element of the printer mounted between said plates is a platen 134: over which the inked ribbon 132 is run, the

said plate carrying a guide 57.4: for properly locating the ribbon over the platen. The platen is carried on a shaft 575 that extends 'beyondtheplate 572, and fixed on the shaft is a ratchet wheel 576.

' Pivotally mounted on a bearing 577 on an ear 578 that extends downwardly from the frame plate 148, which carries the printing hammer mechanism is a bell crank lever 579, the upper arm of which is adapted for engagement with a stud 580 on a crank arm 581 that is fixed to the shaft 13. The lower arm 583of said bell crank lever is adapted for engaging a boss; 584-on the forward which, in turn, is connected with the plate 573 so that-the paWl'isyieIdingIy urged to its locking engagement with the ratchet. With this mechanism, with each movement ofthe main crank shaft the platen is advancedtopresent constantly changing positions to the type. v

, Rotatably mounted in the front ends of the frame plates 572-573 is a shaft 589 carrying a roller 590 and fixed to the roller is a grooved wheel 591 for carrying the belt 592 whlch runs over the wheel 591 and over a wheel 593 which is fixed to the platen, so that when the platen is advanced the roller 590 is also advanced. The belt 592 is of spring construction in order to afford variance in the speed at which the roller 590 is revolved, for the reason that the roller takes up the printed web during the operation of the machine, and as the diameter of the web roll varies, while that of the platen remains fixed, there must be slippage between the parts in order to compensate for the variance in speed at which the take-up roller is advanced as the diameter of the roll increases.

Interposed between the roller 590 and the platen is a tension roller 595 beneath which the web 133 is passed during its travel to its take-up roller after running over the platen, the said tension roller being mounted on stub .shafts 596 in slots 592 in the frame plates 57 2-573, the said shafts having springs 599 connected therewith and with the frame plates in order to constantly urge the roller downwardly and maintain a tension on the, traveling web. I

Located at opposite endsof the platen are yoke brackets 600 and rotatably mounted in said brackets are ribbon drums 601-602, having suitable tensioning devices 603 and provided with gear wheels 604-604'.

Extending transversely across the frame beneath the web strip, and rotatably mounted in the frame plates 572573 is a shaft 606. The shaft 606 carries a gear wheel 608 which meshes with the gear wheel 605 that is fixed to the platen so that the shaft is rotated with the platen. The said shaft 606 is provided with pinions 609 610 which are adapted for-meshing with the gear wheels 601604' on the respective ribbon drums. The gear wheel 608 is slidably keyed on the shaft 606 and held in mesh with the gear wheel on the platen by a tooth 613 on the frame plate 572, and the'said shaft 606 is rotatably mounted in the wheel'608 and its hub 612. The hub 612 is provided with a longitudinal slot 612' for receiving a pin 614 on the shaft 606, 'so that the pin and slot connection will induce rotation of the shaft though permitting longitudinal -movement of the shaft in the gear wheel. The shaft 606 is of'such length that when one of the pinions on the shaft is in mesh with its re- .spective'toothed wheels on a ribbon drum,

the other pinion will be out of mesh with its toothed wheel so that the ribbon drums are driven independently. The shaft may, however, slide in its bearings to reverse the engagement .of the pinions and the direction of travel of the ribbon drum, and as the shaft'is driven for either engagement from the same point in the same direction, and as both of the pinions engage the toothed wheel on the ribbon drums at the inside of the drum axis, the drums are driven in opposite directions The shaft 606 has s aced pe-a ripheral grooves 615-616 adapted for re.-

atransverset-ro'ugh 619 for seating a roll I of web strip and the roll is preferably ar-' ranged so that it will feed from the bottom and thereby provide friction that is proportionate to the weight of therolland is sufficient to prevent slack in the, record web during its feed to theprinting mechanism. To properly position the table 18 and latch it against accidental displacement, we

provide a latch 660, which is preferably ward a'stop pin 663 on the bottom of the table by a spring 664. The other lever arm, 665, has a camend 666'adapted to engage a stud 667 on an inner frame late 36, to

displace the lever andlautomatlcally locatethe notched portion 668 in position toseat .the stud 667 when the table is returned to the inside of the case, the notched portion of the lever being so located and shaped that it will hold the table locked, but permit manual operation of the leverto release the table. a

Assuming the parts to be constructed and assembled as described, with the printer table located within the case of the machine, the operation is as follows:

Upon each operation of the crank shaft struck against the t 'pc to effect the impression through the in ed ribbon onto the paper strip. The return of the crank shaft to original position eifects an engagement of thestud 580 with-the operatin arn'r-of the bell crank lever 579 which us 8 thelever downwardl onto the roc in 1mg, 585 and lifts t e ratchet awl, a vancing' the 7' platen. and, because 0 the belt connection between the platen and; the paper strip take-up roll."advancing'the' latter to move the strip" forwardly and thereby present a fres'hsurface for the next impression,- the advance of the paper strip being the same-in each instance irrespective of the diameter of thetake-up rollbecause of theset cons nectionin the conn'ecting'belt,

mechanism for mg mechamsm.

-V This operation may be continued throughout the day, or for any period, but when the strip is to be taken off or observed for anypurpose, the operator unlocks the door 19 to expose the interior of the case and releases the table by operation of the latch 660 and swings the table out through thedoor opening so thatthe printing on the strip- .may be observed or torn off and removed.

The table may then be swung back intothe case and locked automatically, as previously described.

' "Vhenevcr thestrip is advanced, the inked ribbon is also advanced to present a fresh surface to the; type throu h the gear- 6045-609, the direction 0 travel of the gearing being determined by the position of the oke latch 617, which ma .be shifted manua ly'whe travelof the rib n is to bedesire to secure by Letters-Patent, is{- pivoted beneath the table on a stud 661 and 1 has a handle arm 662 yieldingly urged tonently mounted printer unit movab e as a unit with respect to the register mechanism and comprising strip forwarding mechamsm, operable by the register mechanism when the unit is in functional position.-
