Appliation led April 27, 1906. Serial No; 314,027.

6l State of New York, have invented certttin new and useful Improvements ,in Tv eis a specification.

My invention relates to typ'ewritinv mai Tating mechanism for such machines. I

My invention has for its principal obJect lo provide an improved coluninq'umpeiy or means for quickly and conveniently bringing the carriage to any selected one of a plurality of column positions, intermediate desired.

In the accompanying drawings, Figure 1 .20 is a front to rear vertical sectional view of the mechanism. Fig. 3 is a to ,plan viewof the machine. Fig. 4 is a ragrnentary front elevation of partof the mechanism, parts' of the main framebeing Shown 'in vertical section. Fig. 5 is a view of' part of- 430.1the mechanismv in horizontal section on the line mof Fig. 6. Fig; 6 is a fragmentary View of'part of the mechanism in vertical section substantially-cna line y-.-f1/ of Fig. 5.

ln the several views'l have shown only so much of a typewriting'machine as is necessary to illustrate my invention and parts have been omitted'or! broken or shown .in section as has been found convenient.

- 'My invention is ap licable to typewriting l*JI'he mainframe of Ithe machine shown in the dravvingscoinprises side plates' l that are connected together at the rear by a back plate 2 and at the front of the machine -by 'a front plate 3 and a. ke'yof said side plates is formed togetherncartheir upper ends by ties 6 and which support a top plate v'i'. Posts'loi` brackets 8 rising `from said top plate support a .statienar-yg' carriage .rail 9 having formed in .its oppositeedges grooves or race ways for anti-fi'iction balls or rollers 10 which coperat-e' with rails 11. of a carriage.

which the i'olloiving4 positions being skipped or passed, if-

'the carriage be moved toward lratchet clutch 4teeth on the pinion 23 and. l

ends in brackets 29 and -3() Saidcarriage comprises end pieces 12 in which is pivoted the shaft of a roller laten 13. The carriage rail '9 is inclined rownward'toward the front of the machine at an angle of about 45. The lower forward rail 11 has secured theretoa feed rack 14 that mesheswith two gear wheels 15,'and 16both loosely mounted on a naled at its front and rear ends respectively in frame plates 18 and 19 depending from the top plate 7 The gear-Wheel 15 is operatively connected in any suitable manner with a spring 2O co'xfiled Within a barrel-or drum 21 which is yalso mounted on the shaft 17;

and. this spring acting tlirough'said gear wheel l'drives the carriage in letter space feed direction. f

Themotion' of the carriage under the iinpulse of the spring 20 is controlled-by any suitable cscapement mechanism comprising an escapernent Wheel geared to a shaft 22 which is jou'rnaled at its ends in the frame plates 18 and 19. Said shaft has mounted thereon a pinion 23 with freedom to rotate on the shaft but held against motion longitudinally of `saidshat, said pinion meshing with the gear wheel 1G. Said pinion 23 or its hub has its rear-face formed Wit-hra-tchet clutch teeth that adapted to mesh withl like teeth formed mythe forvard end of a col-lar 24 that is loosely mounted on the shaft 22 and the rear end of which is connected by a tooth and slot connection with a collar 25 that is fastv on or integral with the shaft 22. The collar 24 is yieldin'gly pressed into shaft 17 which is jouiu;

engagement with the hub -of the pinion 23 by a spring 26 compressed between flanges- "of the collars 25 and 24. The construction issuch that when the shaft 22'is held against rotation the carriage is held against tion under the impulse ofthe spring20; i' Aif the righitg* he thefcollar 24 slip past one another.

In order to release ythe carriage from its eseapement mechanism it is only necessary to-force the collar 24 ytoward the rear of 26. To this end said collar is fo'imedwith a peripheral groove into end of an arm 27 of a vertically disposed rocking member 28 that is 'vote which" extends the me themachine against the tension of its spring limit-said claims. tofthe precise form of eeific forme( -of the stops 34 has its lower fork or arm projeetingtoward the front of thMmjachine s. engagement with stop arms or teeth 36 pro-A l l 3i' that rigidly Amounted on a vertical shaft 38, the u per end of which is journaled in claims I have also referred to said stop" tmfrecited the claims.

Ward the front of the machine from'the frame plate 19. It will .be evident that 1f the arm Q7 be pressed toward the rear of the machine the carria e will heI released from its escapement mecianism.

A column stop bar 31 is mounted on the carriage, being suspended bylarms 32 from a rod that joins the side plaies 12 'of the carriage near the upper rear ends'of said plates. The arms B2 hang sul'istantially. vertical and the stop bar 31 is situated just hack ofI and nearly on a level with the top plate 7, Said stop bar 31 is formed on its upper and lower faces with transverse notches a letter space distance apart and columnstops 34 are adapted to be mounted on said stop bal'. Said column stops are of furcated construction and are adapted to he .slipped on to the bar from the rear, the forks of the stops enihracin{g` said bar and fitting into the notches formed in said bar. As shown in the present instance, each of said stops has riveted to one sidethereof a plate spring 35 that is adapted. to enter the notch on the lower side of the bar and by its resiliency to cause a frictional engagement between the stop and the edge of the notch so as to prevent accidental displacement of the stop from its position on the bar. Each slightly in advance of the-bar 31 and theseprojoctingjarms are 'adapted to come into jecting from a rotary toothed stop member the top p ate' 7 'and the lower en d of which projects through the back plate 2v and vis ]ournaled in 'a bearing' 39 secured to said hack plate.

In theoperation of the machine this toothed stop member is opposed to the column stops'B-t'v andl in some ofthe claims I have accordingly referred to said columnstops astabulator stopsand to the rotary stop member .as a counter-stop' Inasmuch this counter-stop comprises a plurality of arms or teeth', each of which in itself is a stop, 'I have also in some of the claims re ferred lto said-rotary stop member asfa com-v 'poundA counter-stop and -in some' of 'A the arms-or teeth asa set of counter-stops. doV not mean these expressions, howeverftol counter-stop or set" of counter-stops shown in this case, bu-txl regard "the x referredftei-faS-fing i distinctly recited/ 11i s'aid climsf--Iln- .thel

ot rotation, that is to say, to the axis of the vertical shaft 38, and some lof the claims are limited to a construction in which the faces of the di'erent stops have this relation; but

is not necessary that the faces of said'stops be thus related., As far as I am aware it is broadly `new to provide a plurality of carringe stops each mounted on a rotary. meml ber that-is rotated hy the carriage to bring one oranother of said stops to operative position, whether or not said stops be Situated on the rotary member in such relative positions that a plane at, right an les to the "axis of said rotary member woul vintersect the, faces of the stops. It will also be observed that the faces-of these several stopsBG lie in planes that intersect one another. In the present instuncethese planes intersect substantially in the axis of the shaft 38.

The column stops or tabulator stops 34 and the counter-stop or set of counter-stops are normally out of coperative relation and means are rovidedfor establishing' a cooperative r'e ation between these two sets of stops. As shown in the present instance, one of these sets of stops is n ormall out of the path of the other, but is mova le into .the

. path of theother, and in the present instance it is the counter-stop or set of counterstos thatis thus made movable.- To this en the shaft 38 ismade movable up and down in itsLbearings. i

The upward motion of, the shaftv 38 is limited by the contact of the toothed member 37 with the upper bearin ofthe shaft, and vits downward motion 'is limited-by a collar 40- making Contact with .the bea ing 39. The shaft normally stands in its lower position, sh'ovvn in F-ig.- 1,. withthe teeth. 36 out ofthe 'path of the column Sto sfvfbutsaid shaft is adapted to be raisedllto bring saidteeth into the path of said'stops b 'means that will resently be described.'

Each of the key levers 52 has pivoted to its vforward end at a key stein Sti that ext-ends upward through a suitable opening in the key-hoard plate 4. Yl`ahulator keys 57 are mounted on 5 the upper ends o'l' the stems 5t.

in the present instance the levers l52m-e arranged side by side and close together throughout thegreater part ot their length, hut near their rear ends all ot' the levers ex 0 cept the tirst are formed with otl'set bends as shown in Fig. 3 in order to space the stop portions 51 of said levers a suitable distance- 'apalt At their forward ends the levers 52 are preferably heut, as shown in Fig. 3, so 5 -as to bringr all of the keys 57 into a straight line fore and aft ot the machine. lhe rear ends ol the key levers 5i). are guided in vertical slots ltormed in thevplate 48.

The construction is such that when any of said key7 levers is operated hy de- ,prer-:sing the appropriate key 57, the unil) versai har is elevated, the shait 07 is 'rocked toward the rear otlv the machine and the shaft 38 is raised hy the arm (Bti, thus bringing thestop teeth 3G into the path of the column stops Bt.

- yIn order to release the carriage when av As shown` tahulator key .is depressed the rock shaft (S7 has mounted thereon a depending arin 7l which is adaptedto engage a cross piece 72 formed on the lower end of an arni 725 that projects downward' froin'a short rock shaft 74 thaty is pivoted onpivot screws threadcd through thearlns of a hrackel i't secured to the under side of the hack plate 2. The

roch shaft T-l has an arm t7 projectingr up- \\'ardly therefrom and adapted to engage the 'l'ront l'aee ol the a-rm 2T. the end ot' which lies in the peripheral tgroove in the collar ill, The eonst rn'etion is such that when the shaft t?? is roeked hy any of the tahulator keylevers the arm 2i' is pressed toward the rear olE the machine and the clutch teeth on the collar "Jf are moved out. of engagei'nent with the eorres|mnding clutch teeth on thehul) o'l the pinion 23, thus freeing:Y the carriage; from the restraint of the eseapement and permitting it to niove under the impulse of its driving spring 2t). In orderv to avoid releasing the carriage before the arms 36 are raised into the path of the column stops, there is lost motion between the arm Tl and the eross-piece 72, as indicated in Fig. 1. The stop teeth 3i) are so' designed that each ol? the column stops 34 in passing said stop piece engages one of said teeth and turns the `rotary stop member a units distance, thus bringing the next succeeding tooth 3(3.into positionl to he engaged hy the next succeedingvcolunni stop 34 and turning the shaft 3th The shaft. 38 and pinion 42 will draw the har 44 toward the left'until the shoulder .50 is arrestedl hy the stop port-ion 5l of thc operated key lever. IlE the first, key leveren ,I

the right has been depressed the har i4 will he arrested aft-.orso slight a motion that the lirsty column stop will he arrested by the first -ar|n 3U, lf the second key lever has been operated the shoulder .50 will be arrested when the second tooth 36 is struck l-)y the second column stop 34, and the carriage will stop at the second Acolunnrposition. If the third or fourth key lever is operated thc carriage will he arrested 'hy thc third ori'oui-th' column stop and at. the third or fourth column position.v

.l'n order to prevent backward rotation of the sha't after it has heen partially turned hy one of the column stops and before the next arm 3l; is engaged by the next succeeding columnV stop, a detent `78 `is t mounted inthe lug 45 just above the raek bar 44, the disposition of the parts being such that when the shaft, 38 is in its elevated'position the pinion 42 is in engagement with the detent 78; but when-the parts are in their norinalv position said pinion isi out, of engagement, with said detent. The detent 78 consists of a squared plungerseated .in a suitable openingl in the lug'lt and having a. rounded stein 79 thatfits into a round hole in said lug. The stem 79 is hollow, as shown in Fig. 5, and a spring 80 is= seated in said stem and compressed between the detent 78 and the inner end of the 3 hole in which the stem 7 9- is seated. The

spring 80 tends to press the deten't toward t e front of the machine, its motion being limited ,by the plate 47 as indicated in Fi 5. The outer end of the detent 1s ma e square and lits into a square opening so as to prevent rotation;' and the end of the detent is formed as shown in Fi 5 with an edge that is adapted to enter -t e space betweenstwo teeth of the pinion 42. Said edg f has-'an abrupt face adapted to prevent bac ward rotation of said lpinion and an inclinedl face which renders t e detent lmovable by -a tooth of the pinion when the shaft is turned by a column stop.

A being indepen entl The operationof my tabulator or column jumper willnbe understood 'from the forego- 1n description. Any desired number of co umn stops 34 may be placed on the bar 31 and suitabl located thereon, the stops adjustable along said bar. I'it 1s desire to brin the carriage to the third columnl osition, or example, vthe tabulator key mar ed 3 I will be depressed,

-this key being connected with the third key lever 52 from the-left; The rear end of the lever 52will velevate the universal bar 70,4

thus rocking the shaft 67 and elevating the shaft 38 and releasing the carriage by the arm 71 engaging the cross piece 72. The elevation of the shaft 38 has brought the arms 36 into the path of the column stops and has also brou ht the pinion 42 into en agement with ytle detent 78. The first coumn stop will strike the first arm 36 and will move this armout of the path' of the sto s and the next succeeding arm into the pat of the sto s, rotating 'the shaft 38 a units distance, in w ich position it will be retained by the detent 7 8: The second stop will strike the second arm 36 vand willmove it and the shaft 38 in the same manner, thus turning said shaft" 38 a second units distance and bringing the shoulder close to the operated key lever., 4The third column sto therefore, will beunable to turn the

sha t

38 and 50 will be arrested by the third stop arm 36. When the key is released the sleeve 24-will move toward the front of the machine, bringingfits clutch teeth again into engage'- ment with the clutch teeth on the pinion 23, thus retaining the carriage in the position where it has been arrested. The shaft 38 will drop to its lower position, thus' bringing 4the armsv 36 out of the paths of the stops 34 and leaving the carriage free to move either way without interference vby saidv f arms 36. The-pinion; 42 will escape from the detent 78 xand the spring 61 will restore ,the bar 44 toits normal position in which it is arrested by a pin 81 projecting from said Vbar and'engagingthe plate 48. In this position the lirst arm 36 isw'ih the position Ashown in Fig. 2, that is to'say, it in .such position that when the shaft 38 1s again column keys but it will be obvious that any i desired number maybe provided. If, in the :present construction, it is desirable -to use more vkthan four column stops the carriage can be brought toany column beyond the fourth by a plurality of operations of the keys. For example, if it is desired to bring the carriage to the seventh column position, this' can be done by operating the fourth column key, thus'bringing the carriage to the fourth position and then operating the third column key which will result in the carriage being-arrested .by the seventh column stop. By reference to Fig.4 it will be seen that' the shoulder-50 will move a short distance before it will be arrested by 'the first column key so that when this key is operated 4the first arm 36 moves alittle to the left under the impulse of Kthe column stop .and whenvthe key 1s released the stop returns to its normal position. This, taken together with the fact that there is a slight lost motion in the connection between the carriage and its escapement mechanism, will insure that'the stop 34'will come to rest to the left of the arm 36 so that in case the tabulator is operated twice without any intervening operation of the escapement, the column stop rst arrested will have passed to a position where it will not interfere-with the`second raising of the' shaft 38. 1

The escapement mechanism may be of any suitable sort. xIn the present instance, I have showna small universal barV 84 mounted on a lever 85 andv situated near thev printing point in position to be struck by a -contact portion 86 of the type bar 87 1ivh'en the latter is thrown up to print.` The lever 85 #on whichthe universal bar is mountedis pivoted at 88 to a bracket 89 secured to the front face of the frame plate 18. In said bracket there is journaled a shaft 90, having at its lower end a skew pinion 91, meshin with a gear wheel 92 mounted on the sha 22.` At its upper end, the shaft carriesa single tooth 93 that is .controlled by feed dogsf94 on` the lo'wer end of the lever-'85. The construction is such that when the universal bar 84 is struck by vany type bar, the lever 85 is oscillated and the toctli is-teni leased, permitting the shaft 90 to makeondl complete rotation, thus imparting letterspace feed to the carriage.

It will be observed that my column Jumper is of such construction that it is not necessary to make any difference between theA different column stops A34 as has been usual A heretofore 1n column` jumper mechanisms.

A column is selected'notby-selecting a col-1A by registering, or, inl efi'ect,`connting, or

tion 'with the carriage and escapenienbnief-h I stop, etc.

keeping tally of the column stops as they pass the rotary member 37. The first key arrests the Erst stop that reaches said rotary member, the second key arrests the second arrest the third column stop. the secondv key will be depressed instead of the third. It will be obvious that this counting or registering of the column stops may be effected by means differing greatly from that here shown. As far as I am aware this principle is .broadly new in tabulator mechanism and my claims are intended to cover broadly all tabulator devices made in accordance with .said principle. i v

lVhen the carriage is at its extreme righthand position the column or tabulator stops all face the counter-stop, and in the present instance vin which said column4 stops are mounted on the carriage, the column or tabulator sto which is then next to or Which .pruxiinatey faces thecounter-,stop is the first stop from the left end of the stop bar. l't. will be 'understoodtha/t thecolumn or tabiilator stops /niay be made to coact suc? cessively .with he counter-stops as theA carriage travels.A toiv'ard lthe le it. andthat by pressing the properkey a tab latorfstop bel-l liindi'iorlin the present instant` tothe right f' of, th/atpi'hi'ch proximately faces said coun.-l

t'er-stop,"mayl'bc made to coact with. said counter-stop to effect the arrestof the carriage after it is released from the step-by- .step feeding mechanism and before it is otherwise nisin.

Various other changes besides those indicated in the body of the specification may7 be made in the detailsof construction and arrangement without departing from my invention.
