TABULATING Mncnamsir non ADDING-'naam To all whom, it may concern Be it vknown that L'JOHN J. CHAPIN, a

citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a certain new and' useful Improvement in Tabulatin Mecha nism for Adding-Machines, of whic the following is a specification:

The invention relates to adding machines or other recording. machines which' are adapted to produce tabulated work upon p aper supported in a laterally shiftable carriagesuch e. g. as that commonly employed in adding-machines and typewriting machines wherein the paper overli s a .roller platen.

The chief object of the present invention is to provide for automatically shifting the carriage in columnar positions without regard to any regular-order orrsuccession of columns. Thus the operator of the machine tabulating a miscellaneous collection or series of items can by the mere depression of a selected Vkey cause the carriage to automatically'move to any columnar position within the range of its capabilities, whether such columnar position is in advance of others or is one precedent to that lastI occupied, and if the carriage in moving from one columnar position to another is required to pass one or more intermediate columnar positions it will travel the whole distance .backward or forward automatically without requiring repeated manipulation of a key or other controlling device, the movement however extensive being continuous as distinguished from a step by step movement. It is obvious that an arrangement of this sort will provide for more readily and expeditiously tabulating miscellaneous items which do not occur in regular order as related to the succession of columns across a sheet of paper. v

With the above and incidental objects in view the invention consists incertain novel features of construction and combinations of arts the essential elements whereof are recited in the appended claims, and the prel ferred form of embodiment of which is deform part of this specifcatlon.

scribed in'detail hereinafter and illustrated in full in the accompanying drawings which Of saiddrawings Figure 1 represents an adding machine of the -well knownBur- Specincation of Letterarastent.

It will be unnecessary todescribe the adding machine proper which is not vitally concerned in the o erations of the tabulating ,mechanism o the present invention. The `latter is notv dependent upon the presmechanism though of course*v in practice it would necessarily be employed with some sort of recording devices. It will suice therefore to merely point out a few of the well known elements ofv the'addin machine lpfloper which is herey shown as o the well own vBurroughs type, The usual keys forI setting up amounts are designated by the so lstill different condition is re resented,

l'. The roller-platen is designated by the numoral 17 and occupies the'usual position at therear of the machine being carried by-a 2 'laterally Ashiftable carriage 2 running u'pon roller bearings of a bracket 3secured to the. f rame work of themachine. The shifting Y `of this `'carriage is done by amotor through w lofthe medium of friction clutches and-revers'- gearing. In the present 4instance an electric'motor iscoupled lto a' worm /and Y Y the latter engages a worm wheel 6 secured to a 'shaft 7 whichis journaledin. side arms 8 Y of'a bracket 8 on theback ofthe machine vframe. Clutch disks9 and 9* have grooved s yhubs 10 and lotsliding upon said'shaft and g pins 1 1 and 11a sliding in collars A. 12' and 12'* which; are fast-withthe shaft Y and consequently rotate said clutch disks constantly.' v The latter are faced with friction rings 13 and 13" which confront clutch' v disks 14 and"`14 loose upon the shaft and Vsecured respectively to the hubs ofv bevelk gears 15 and 15". Springs 16 and 16B,jsur' rounding the shaft between the disks ofthe two` clutches tend to force them apart -and do so normally as illustrated in Figa, so

l A fthatno movement is imparted tothe gears and-15%,. These gears both mesh with a 1 'bevel gear 17 secured to the lower end of a vtending portions 3'* shaft 18 jeurnaled in arms .8 and 8i of the bracket 8 'and carrying at its upper end a spungear pinion 19 inmesh withthe rack '20 on the carriage 2.

andl -rearwardly ex- Be'tweengdepen alli the end pieces of the fixedbracket there extends a rock shaft 21 which carries spaced along it a series of tabator stopA ,fingers 22 lrallydisposed as p v t by turn- -ingth'e shaft 21 more or less on or another of theselngers may bebrought inte effective position, which, under Athe organization' here shown, is the upright'` position "ch the near end Yfinger occupies in Figs. and 2.

It will be obvious t at the carriage moving either direction will be stopped by the encounter of one ortho other of these pieces 23 with the empfnger 22 which is occup the effective position and furthermore tlyamg I a the vengagement of such finger between the tw pieces 23 will -msure 'a -stable columnar position of the machine.

These keys surmount stems 26 sliding through the familiar keyboard plates 212 and 213 and` al'so sliding through a specially entering portlons ofthe framework of the v At its rear end this'bar 31 has` rack teeth 33 in its upper edgeengaging a gear wheel 34. secured to the left-hand end of the shaft 21. The rear inclined-edges of the cam projections-30 are graded in angularity and so likewise are' the front inclined edges of said cam projections, so that the keys act'with uniformly increasing effect to shift'the bar 31. Thus said bar having been v moved all the way forward bydepression .of .the 6 key as represented in Fig. 1, the. 5.

key will move the bar backward the least distance, or what may be considered a unit of movement. The 4 key will move it twice as far, the 3 key three as far and so on,

and of course the stop projections 22 will be positioned accordingly. inclined edges of t e cam projections lare concerned, whereas if the bar' has been ,Here the forward shifted allthe way rearward by depression of the 1 key, then of course the 'rea-r inclined edges of the cam projections will be brought Y 4' below the rollers 29 respectively and conditions are reversed inthat movement of the bar lessens as the keys 25 extend rearward. Thisv means of course that therearincline'd edgesl of fthe camrejections are reversed as tov relative an arit4 'as compared with the series of front inc ined edges of said cam projections. At the bases of the projections rounded sockets 33-are formedfor the rollers 29l .to seatin thereb insuring an exactpositioning of the shiftab .e bar and consequently of thev tabulator projectlon 22 which is tocontrol the position of kthe carriage. To guard against any shiftin of the .v

bar 31 when the keys are diseugage there from, a series of saw teeth 34 are formel` 1n 1g. 1 and engaged by a sprinheld pawl` 35, thefen agement of whose V-s saw teleth 34 causes suicient friction to prevent accidental shifting ofthe bar.

n is thought that. it win now be perfectly 1 selected key 25 which act results through the aped nose with i Aone or another of the notches between` the p medium of the device above described, in disengaging one finger 422- from the stop pieces 23 and bringing another of the stop fingers 22 into line with said stop pieces so that when the carriage moves one way or the other one of these stop pieces.; 23 will wipe past the newly positioned stop finger and the other stop' piece will abut against such finger which will then be confined be# tween the stop pieces and will hold the c'ar.-

riage against movement in either direction.

25 end of the said bar 31 (see Figs. 1 and 1*).

The rear end of this bar 38 is upturned as shown in Fig. l1 and pivotally connectedto the upstanding arm of a bell crank lever 40 which is pivoted upon the screw 32 occupying the slot at the rear end of the bar 31. .The rearwardly-extending arm of this bell crank lever 40 engages under a' roller 41 on the end of the horizontally-extending arm of another bell crank lever 42 workin -in a plane at right angles to the bell cranlever 40, see Fig. 3, this bell crank lever 42 being pivoted at 43 to the back of the machine. A

latch lever 44 of bell Fcrank form is pivoted at 45 to the downwardly vextending arm' of 4`0 -the bell crank lever 42A and has a catch shoulder 46 normally engaging a pin 47 on the upper arm of a clutch closing lever 48 pivoted in a bifurcafed post onM one of the `bracket arms 8a and forked to embrace the' 45 sleeve or hub l0 of the clutch disk 9, the fork having pins or studs occupying the groove 25 through the medium of devices. described. Besides the rollers 2S)4 -left until itencounters the l 21 is rocked in a direction to carry a higher cated by the arrow in Fig. 2 and so the result of closlng the clutch as above described will be to propelthe carriage to the left as the machine would be viewed from the front, which of course means to the right as the machine is viewed from the rear as in Fig. '3. If at the-.time of depressing one of the tabultor keys 25 the carriage is not at the extreme columnar position illustrated in Fig. 3 and is to move to a columnar position farther to theleft than it is occupying at--the time the key is depressed, then the effect will be simply such as above described, that is to say, the tabulator stop finger 22 which has been holding the carriage at a certain columnar position :will be disengaged from the carriage and the latter will move on to the newly set stop finger whether it be the next one on the shaft 2l or a stop finger farther on. However, if the new columnar position which the carriage is to occupy is farther to the right than the columnar position it already oc-4 cupies, then obviously something further is required to take place for the carriage must necessarily shift the other way. According to the present invention as here carried out, the carriage wouldnot immediately shift in the reverse direction, under the circumstances 'just mentioned, but would first travel to the extremevof its movement left- Ward and then automatically reverse and travel back to the newly positioned sto finger. It is obvious that when the sh'a t numbered vcolumn stopfinger out of effective position and bring a lower numbered column stop vfinger into effective position, the carriage is necessarily released forV movement leftwardunobstructed by a column -stop finger since the stop pieces 23 are already leftward of the newly positioned 4column stop finger. Thus rocking of the shaft 21 4in the direction of the arrow, Fig. 2, disof said hub. It follows from the form and f arrangement ofparts just above described, that depression of any one of the keys 25 50, causes a forward thrust ofthe bar 38 and lconsequently upward movement of the'rear- Wardly-extending arm of the bell crank v40 and corresponding movement of the hori- Hzontally-extending arm of the bell crank 4 2 55 and consequent swinging of. the downwardly extending arm of the latter bell crank in a direction to cause thelatch lever v 44 to voperate the clutch lever 48 and force p i, the clutch disk flinto frictional engagement. 60 with the companion clutch disk 14. This will. obviously result in propulsion of the carriageby the motor in a direction or# dained by the gearing connections hereinbefore descrlbed. Themotor-drlven worm '65 5 rotates constantly in the direction indi-- engages the sixth'` column stop finger from 110 the carriage and leaves the latter freeI to move farther leftward, the newly positioned column stop finger being located to the rightv so that it necessarily awaits a return movement of the carriagein order to perform its function of locating the carriage in a new columnar position. The arrangement for automatically reversing the movement ofthe carriage under control of the. tabulatolrkeys, is of the fol- 12o lowingl description: The before-mentioned lever 44 is pivotally.connected-at its upper -end `with a bar 50 which extends horizontally and has an upturned end v50a standing in the path of movement of a plate or finger 52 secured to and depending from the righthand end of the carriage. The'result is that when the carriage is released under such circumstances as above mentioned so it movesy beyond the lastl columnar position', this plate 130 equipped rwith studs or pinsv occupying the or linger 52 strikes the upturned lend of the tappet bar 50 disengaging the latch lever 44 groove of said hub. A spring 54 'applied to this lever tends to swing it in a'direction to close the clutch but is normally restrained by a latch lever 55 which is ivoted to' the arm 8d of the bracket 8 an has. a catch shoulder 56 engaging apin 57 operating lever 53. The upper end ofthe jlatch lever 55 ispivotally connected to the tappet bar 50. Consequently, when said bar is shifted as before described it not only disengages the latch-lever 44 from the clutch operating lever 48, but also disengages the4 latch4 lever 55 from the clutch operating lever 53. The catch vshoulder '56 of this latch lever 55Y is elongated as compared with the catch shoulder 46 of the latch lever `44 forthe purpose of delaying the release of the clutch operating lever 53'V until after the clutch operating lever 48 has been released thus insuring that the clutch shall open before the carriage returning clutch closes. Fig. 5 illustrates the congitglcm whenthe carriage is about to start In order to provide for the opening of the. carriage returning clutch Jwhen. it' has fully performed its function,

` lever 53 is operatively connected with the bell crank lever 42 so that upon ease of the tabulator key and consequent returnto normal o`said bell crank lever 42 b its spring 42, the said clutch operating ever will be swung back to itsoriginal positiony opening the clutch. Tof'this end a ever 6.0 is pivoted to a portion of the bracket 8 and coupled on opposite sides of its pivot with two'links 61, 62, the former coupled to the downwardly extending arm of the bell crank 42 and the link'62 slotted to enga e a stud at the upper end of the clutc ever 53. (The slot provides j for the' reliminary movement of thelever and resulting from depression of the tabulator key, without such movement agecting the clutch lever or being interfered with by the latter). It

Ycolumnar positions, there should be no auytomatic line spacing in the sense of linesp'acingvwithout intervention by the operator. On the contrary it is desirable that line spacing vshall occur only as predetermined by the operator since the last. item in the horizontal series may occur at any columnar position. To this end a special key is provided for the operator to use whenever he has filled out one horizontal line and desires tostart another. In this connection it may be stated furthermore that it is preferable that the line acing take lace in the same operation whic prints the st item of a new horizontal line, rather than in theoperation which prints the last item in the preceding horizontal line. There isless likelihood of a failure to line space if the construction of the machine provides for the line spacing being done' in connection with the starting of a new horizontal line,

"for of course the operator would be more likely to think of the necessity for line spacing when 'starting a new series of items than when completing a series by the printing of an item at any one of a number ofA columnar positions. .Therefore the line spac' mechy Bresent machine is m fied as compared wit line spacing mechanism heretofore used in this class of machines, so as to provide for line spacing durin the forward pull of theoperating han e instead Aof during the return movement thereof.

'los

Referring to Figs. 1, 6 and 7 the reference numeral 60* designates a line spacing lever similar to that ordinarily employed in these machines, thesame ca a rollen-60" at `its forward'iid andbeingpcoupled at its rear end to a .slide 6,1' arrangedto recipro cate verticall'yon the back. anel of the machine and vibrating a bail .The latteris secured to a rock shaft63 hich has anarm 64 connectedby a link '65 with a'pawl-carlryngarm 66 loose on the laten shaft 67 and carr g a spring-hel pawl' 68. .A- whlexl 69 is secured to the platen and fthe pawlis adapted to act upon said ratchet wheel upon such movement 'of the lever 60 as would ordinarily take .place when the handle ofv 'the machineis-pulled forward.-

(Thisisthe reverse of the usual when movmcef .da 1m1- es gef. 1j

. of the operating handle, the pawl takes effect to turn the platen). An adjustable shield is here shown for regulating the extent to which the pawl 68 will turnv the roller platen.

In order to provide for controlling the effectiveness of the line spacing mechanism so that it will act or not accordingto the election of the user, a modified form of cam for co-acting with the lever 60 is employed.

Ordinarily the roller 6()b occupies a cam slot of a cam piece secured to the rock shaft 100 so that in every operation of the machine vthe lever 60 is vibrated. In the present instance there is a cam piece 121 yfastened to said shaft 100 but instead of having such a cam slotitl has an interior edge 121a .corresponding only with one side of such slot, and is opened out in the center and formed with an opposite interior edge 121b whichis concentric with the shaft 100. A spring72 applied to the lever 60 tends to rock the same so as to effect line spacing as governed by the cam edge 1212L upon oscillation of the shaft 100 produced by forward pullv of the operating handle. However, said spring is normally prevented from so aii'ecting said lever 60a and in consequence the concentric edge 121'J travels in contact with the roller 60h and there is no movement of said lever 60a. This restraint of the latter -isv effected through the medium of an arm 73 secured t0 the same shaft 60 to whichithe said lever 60 is secured, see Fig. 7, said va`rm having a pin 0r stud 73" at its upper end (Fig. 6) normally engaged with a latch arm 7 4. The spring 7 2 is directly applied to a forward branch of.

the arm 7 3 and obviously tends to rock the latter rearward and the lever 60a correspondingly so asto effect the line spacing.

Said spring being attached at its opposite .end to the latch arm 74 also serves to enforce key against the` stress of said spring will disengage the latch arm .74 from the stud 7 3 and so free the arm 73 and lever 60a.' v

To avoid having to hold the key down throughout the operation, a latch is provided for detaining the arm 74, .said latch being in the form of a lever 78 having a catch shoul? der 7 8a adapted to engage a stud 74* onf/the arm 74, as illustrated by dotted lines in Fig. 6. A ,spring 79 applied to the lever78 enforces the engagement. A downward extension ofthe latch lever 78 having a curved rear edge for engagement with the 'stud 74,

parts in operation. 4

It will be obvious from what has been 73, will preserve the proper relation of above explained that when the key 77 is depressed and the machinethen operated the a rearward rocking of the cam piece 121 will be accompanied by a rocking of the lever 60* and a turning forward of the roller platen. Then of course with lthe return of the operating handle the forward rocking of Said cam piece will retract the pawl. To rovide forme-locking of the lever 60 at t e conclusion of the operation, the latch lever 78 is extended upward for engagement with a stud 80 carried by the familiar vibratory amount key restoring bail 202. A

To provide for having the linel spacing mechanism operate repeatedly as when single column work may be in progress, the key stem 76 is formed with La notch 7 6 adapted to engage under the upper keyboard plate 219, the lower keyboard plate 213 bein slotted to permit the necessary rearwar movement of the key stem. A comparatively light spring 81, applied to the key stem 76, prevents the notch from so engaging with the upper keyboard plate 212 unless the operator forcibly thrusts the key rearward after'full depressing it.
