To cllwhom 'it may concern.' x

Beit known that I, ALnXANDnRT. BROWN,

:l citizen ofthe UnitedV States, and resident of Syracuse, lin the county of Onondaga and Statel of New York, have-invented certain new and useful Improvements 1n Type- 4 AVVritin Machines, of which the following is may be set by direct reference tothe paperl in the machine without necessity for the use of any scales. l

To these and other objects which will a ear hereinafter m invention consists in certain features of construction and com.-y

'hinations and arrangements of'parts, all of vwhich will be I. fully set forth herein and particularly pointed out in the claims.

strike 'typewri'ting' machine, only so `much of said machine being shown, however," as-,is necessary to illustrate my invention. 4 y,

y ln said drawings, Figurel is a front to rear vvertical sectional view' of the typewritf ing machine'having my invention embodied.

therein. Fig. 2 is a front elevation of the same. Fig. 3 is a rear elevation of the same. i

F io'. 4 is a bottom view ofthe same. y

fn all the views parts h'ave been omitted and in some of them partsare shown broken away or in section. l l

My invention is applicable to typewriting machines generally. The main frame of the machine shown in the drawings comprises side plates 1 having cast integral therewith corner posts 2, the posts on each side of vthel machine' being connected together near their upper ends byan integral'bar 3. The side plates are connected together at theirtops by a top plate 4 secured tothe upper ends of the posts 2'and at the base of the machine the side plates are lconnected by a. back plate 5, a. front plate (S and a plate 7 through openings in which the stems of the printing keys project. The'l top plate has for a further Tobject to. provide means whereby the column *sto-ps an openin 8 4throl'igh which the type bars stri-ke, sai opening being` closed across theront by a cross barl 10 cast integral with' the top plate. A At the rear of the openn 0 '8 the top plate is formed into' a dust shieldy 11 to protectthe type bar bearings from dust and grit falling upon the front face of the laten. I have hot deemed it necessary to illustrate the type action in this case, as, so 4far as the present invention is concerned, said type'action may be of any suitable construction.

Standards 12 rising from the top plate 4support a stationary carriage rail 13 set at an inclination upward and toward the back of the machine and having in its` opposite edges grooves forming ball races for antifriction balls lat-which cooperate with rails 15 and 16l forming parts of the carriage. Said rails are connected at their ends to end pieces 17 which support the axle or vshaft 18 of the roller4 platen 20. 0n the -ends of l said platen axle are mounted theusual iinger Wheels 21. The precise manner in which the platen is mounted in the carriage is inlmaterial so far as the present invention is concerned, .but it will be seen by reference to Fig. 1 that the shaft 18 restsin notches in In the accompanying drawings I .havel shown my invention applied to a front' the end pieces 17 of the carriage and by reference to 'Fig 2 it will be seen that ythe-.shaft is journaled in a platen vframe and 'coi-nprlses end bars- 22 connected together beneath the platen-by a longitudinally exlending rod 23. This rod supports a paper apron' y24 which at its forward edge carries the 4platen and carriage scale 25.

have not been fully shown for the reason that the -ward and rear ends respectively in frame )lates 31 and 32 constituting parts of a These parts rame secured to and depending from the top plate. The gear Wheel 27 is connected 'in any suitable manner with a spring 33 mounted in -a spring drum 34 concentric .'with the shaft 30 and this spring and gear drive the carriage toward the left. The motion of said carriage is controlled by the gear wheel 28 which meshes with a pinion 35 rotatably mounted on a shaft 36 journaled at its ends in the frame plates 31 and 32.4 The rear face of the pinion 35 'is formed rotate with said shaft bya tooth 38 that` with ratchet clutch teeth as shown in Fig. 1, said clutch teeth normally meshing with corresponding teeth on a sleeve 37 slidably mounted on the shaft 36 kbut impelled to plays in a corresponding slot in the sleeve 37; Said sleeve 37 is pressed toward the front of the machine by a spring (not shown) The construction is such that when said sleeve is in its normal position with its clutch teeth in engagement with the clutch teeth on the pinion 35, the carriagewillforce the shaft 36 torotate when said carriage moves toward the left, but saidcarriage may be drawn toward the right without rotating the shaft 36, the ratchet clutch teeth yielding when the motion is in this direction. The

'sha escapement may be of any suitable construcesca ement wheel may be mounted on the 36 or` geared to said shaft and the formed as shown in Fig. 1 with a peripheral groove into which projects the end of an arm '40 (Figs. 1 and 2) said armprojectiug from orforming part of a vertlcally disy posed rocking member 41 pivoted at its uppositions shown in more accessible position for the per and lower ends .in brackets 42 projecting toward the front of the machine from the frame plate 32. vSo far as my invention is concerned, however, the carriage may be fed and therelease be effected by any suitable means. Y

The tabulator vmechanism comprises one or more column stops l43 which are mounted on and are adjustable longitudinally of a rackor column stop bar 44 which at its ends .is mounted on arms 45 depending fromthe upper rear part of the carriage, so that the bar 44l hangs at about the level of the top plate. The arms 45 are so mounted on the carriage as to be capable'of swinging Vto the otted .lines in Fig. 1, or still further to the positions shown in Fig. 2 so as to bring the stop bar or rack 44 to a urpose of adjusting the stops and also in or er to bring said stop bar to a position where the sto s can be adjusted with direct reference to t e paper in the machine without the necessity for referring to any scale. This may be brought about by any one of a variety of constructions, but I prefer the construction shown in the drawings. As shown, the arms 45 are mounted on a rock shaft 46 to which said arms are rigidly securedgby pins 47 passing through the hubs of the arms and through the shaft. Said shaft 46 passes through the end pieces 17 of the carriage with reedom to rotate therein, and the arms` 45, contacting with the inner faces of said end pieces, prevent longitudinal motion of the shaft. Said shaft 46arms 45`and bar 44 constitute a swinging frame that normally stands in the position shown in Fig. 3 and shown in full lines in Fig. 1.` In o rder to hold the frame' in this position a Hat spring 48 is secured by screws 50 to the upper carriage rail 15 and said s ring presses up against the under side o -t e hub of one of the arms 45. This hub is formed with a nose 51 so'that when the swinging frame is in its normal position the spring pressing'against this nose tends to hold it in normal position, but by the time the frame has been swung to the position shown in dotted lines in Fig. 1 the spring either becomes neutral or tends to throw the frame still farther toward the front of Ithe machine. l

The motion of the swinging frame under the impulse of the spring 4 8 is limited by stop lugs52 formed on the arms 45 contactin with the rear face-of the upper carriage rail 15. The rack or stop bar 44 isof the usual construction, that is to say, it is substantially square in cross section and is formed 'on two opposite sides with a series ot' cross cuts or slots spaced a letter space distance apart and the column stops 43' are made of U-shape so as to straddle the bar and so as to be inserted in any desired pair of these opposite slots. In Fig. 3 I have shown the rear face of the bar graduated with graduations corresponding to the cai'- riage and platen scale 25, but in some instances these graduations may be omitted. It will be noted that in the normal position of the bar the numerals of the scale are invcrted, Vso that sai-d numerals are in the proper position to be read when the bar is swung to the position shown in dotted lines in Fig. 1.

The cooperating tabulator stops consist in the present instance of the upper ends ot' a series of upstanding bars 53' having the form shown in Figs. 1 and 3. The upper ends ol these bars come up behind' the top plate iwhere they are guided in suitable slotsI formed in a guide plate 54, which plate is horizontally disposed and is secured by screws 55 to the under side of the rear i'lange of thetop plate. The bars 53 are curved toward the front of the machine and then downward so as to pass in front of the rear frame plate 5. bringinr the lower ends ot' said bars inside ot' the Jase ot' the machine. Each of said bars has its lower end pivoted at 56 to the rear end of the right-hand branch 57 ot one of a series of yoke-shaped frames; each of which comprises besides the tion 'attheextreme right, this being the re.

asses? arm or branch 57 a yoke bar 5K8 and a. lefthand branch orl arm`7 59. These yoke frames are nested asshown yin Fig. 4 and they are all -pivoted on a rod 6lV mounted inears 62 depending from a cross barwhich at itsends is secured by screws v64E tofbrackets 65 projecting inward'from theside plates 1.

In order 'tot space the yoke frames apart the' arms 57 thereof have washers 66 strung on the rod 61 between the several arms. f One purpose of the yoke frames is tol give wide bearings yfor the arms :E7-which are in eiiect lever` arms. 1 Another purpose of these yoke framesis to""reverse the'order of the kkeys with y'relation toy the denomination stops.

Denominational tabulators as ordinarily constructed'heretofore have usually had the keyi'corresponding to the decimal point at the extreme left of the series of keys andthe key corresponding to the highest denominaverse of lthe order of the digits and decimal point as actually written on the aper. lt is desirable to'make lthe order fo" the keys the reverse to that just recited so as' to bring said keys into the natural order in which the numbers arewritten. To this end the keys are connected with the left hand branches 59 of the yoke frames, these branches being larranged in the reverse order to the branches 57 to which the stops are connected.

The tabulator keys 67 are arranged in or near the keyboard of the machine, being disposed in a-transverse' rowVba/ck ofand a little above the rear row of printing keys.

i Said keys 67 have long vkey stems 68,1said cured to the arms 59' by rivets 72.

' operated. e5`

stems, as shownfi'mthe resent instance, being lmade of sheet metag and thekeys consisting of the forwardly bent upper ends of the stems. Each of the key lstems 68 is piv' oted at`70 to the'forward` end of a lever arm 7l, the rear enti of which -forms part of or is rigidly secured to me of the branches 59 of the nested yoke fr" mes. Asshown in the present instance, the'lever arms 71. are se,- 'lhe arms 7l have their forward vends disposed'in any properly with-thel arms 59. The lever arms 71 he beneath the yoke frames as shown in Figs. 1 and 4, the rear'end ol each of 'said arms extending upward 'to the point'whcre' it is connected with the zii'nfill.v A; sp'ace is thus lett. between theseveral yoke bars .i8

and the several lever arms 71 so, thatwhen any key 1s depressed and its corresponding` yoke bar 58 is alsodepressed there-is space enough forkthe downward motion of said yoke bar without strikingthc lever arms-71- com1ected`with those Ikeys that have not been y lt will be perceived that Aeach key is con;

z the correspondin 4andspace the two plates apart.

.that the rear 'end of the arm 57 has a tabulator stop connected therewith. Each of'the arms 57 ist'herefore in effect a rearwardly extending arm of a 'lever of the first order, lever arm 71 being the -forwardlyvextendmg arm of the same lever. The construction is such that when any key 67 is depressed the corresponding stop bar n53 is elevated vertically into the path of the column stops 43. Itv will also ybe perceived that these levers of the first order are crossed, each one crossing all of the others so that the rearwardly extending arms'of said levers which 'are connected with the stops areal`- ranged in an order the reverse of that of the forwardl extending arms which are connected wit i. the keys.

The -tabulator stops and their connections are restored to and retainedyin normal position bya series of leaf springs 73 which press downward on .the upper edges of the arms 57. l As shown in the present instance these springs are formed for convenience as fingers Flower edges bent toward the rear of the machine -to form upper and ylower-flanges nected with a lever arm 7l which is rigidly f 81` and 82 which contact with the plate 76 The key stems come up between the plates 78 and 76 and are guided'in suitable notches cnt'` 'in the flanges 81 and82, as shown in Fig. 1.

The edges of these notches prevent motion of the key stems toward the right or left and the bottoms of the notches prevent motion of the key stems toward the front -ot the -machine Motion of saidkey stems towalrd the rear vof the machine is prevented yby a rib 83 struck up from the plate 76 and plate 78'toward the rearv or by -formedeither bybending the lower edge, of 4the -bending the lowenedge of the plate 76 toward" the' front. The guiding devices` fjust" described are preferably arranged to coperate with the key stems having their `flat sides toward theI front and rear of the machine, but below said guiding ldevices said key stemsl are twisted through y about a quarter turn so as to connect properly with the lever arms 71.' lt will he .seen v that the denomination stops and their keys and connections are all built into the machine but all of these parts are very readily detachable from the machine. The keys anil A, the key stemsy with the bars 53' may be revmoved by removing the screws 65 Which seenre the `bei' 68 in pleee- With these t'Wo parte freed 'from vthe framework ,then thie entire part of themeclianism may be dropped ont ofthe .rneehine from below enfl the guide/Plate 54 may be rleinoved, if Ldeslred, by removing the screws 55. 1-here will thne renieininthe machine none of the tabulato'r mechanism excepty the swinging rack'which is'not ordinarily removed from the machine. When themabulator mechanism is removed from the'm'achine a plain plate of sheet metal may be, substituted for the plate 7 G, for the sake of appearance, if

desired. The denominational values of the several-keysare indicated'b'y numerals or 'other Characters printed orotherwiee iin: pressed on the front face of the plate '78 as Indicated in Fig. 2 Where it will be seen that these keys are arranged in their natural order instead of in the reverse order as has been usual heretofore.- l

In order to release the carriage` when any tabulatorrke is depressed, a universal bar 84 iS Provi ed, Serri' universel ber lying across all of the- arms 57 and 59 near -the rear ends thereof. I-prefer'to arran e .the

universal bar across both .the armsli 59 so that said universal bar will be properly operated in case there should be any yielding in the .voke'frernes when e keyie -depreeeed as `there is more resistance offered to the operatien of the universal bar than v Athere-is'to the operation'of" the tabulator Stopv itself Seid universel ber is eer'rieri .by'srins S5 mounted on einheit 86 the@ .iS Jn'onnted in enreor luge 87 Projeoting )from theend pieoe .5 v.ofthe mainframe! @ne of .the irme 85 has Proieeling downwelrrily therefrom a lever orne 88 irhieh' iS dried to'coperete ,with n, eroSS nieoe'or Wrist pin 8 0 vprojecting from'a lever arm 91 lwhich in turnl projects from a or' short rock ehn-ft 92: pivoted'in eers 93 Proieieting troni the Iframe piece 5'. An arm 94' projecting upward from 'the rockshaft' or hub 92 has its upper end Standing J'nenin front of the arm 40 of the carriage release device. The construction 'is such that `when 'any tabu# lator key is operated the universalfbar 84 is raised and the arm 94 is moved toward the .reen of the rneehine,l Carrying with it the arm 40 and the' sleeve 37 and moving the clutch teeth on said sleeve. out of eilgge' ment with the clutchteeth on the pinion 35. thusreleasng the carriage and when said key is releasedl the sleeve-37 is pressed toward.

the front yof the machine by its spring, bringing the clutch teeth again into engage` ment and thus restoring .the C21-Triage to the control of -the escapement. yIt will, of course, be understood that by the same depression of the key one of the bars 53 is moved vupward ifnto the path of the column stops ,to arrest the carriage.

The construction of the arts is such as to make it convenient to a just the column stops A3 by ldirect reference to the paper itself. The manner in which this may be done is illustrated in Fig. 2whereasheet of paper 95 is shown inplace in the machine and having lines 9,6 ruled thereon definino' columns. The rack 44 is swungv forward towardthe fronty of the machine and the paper thrust beneath vand 4behind it between the arms 45. The column stops are'tlien set on theJ rack or bar 44 to corres ond with thel lines 9.6 asshown in Fig. 2. s here shown one of these lines happens to come at the sixth letter space vrosltion on Ithe/scale 25, anotherat the fortietll, another at the sixtyrst and another at the sixty-ninth letter ispace position. Another column stop is 'shown in the act of being inserted at thc thirteenth letter space position, although there is no ruled line on the paper at this position. It-Will, of course, be understood that the stops may be set by reference `directly to the paper whether there be ruled lines or not.

@In Fig. 3 the column stops are swung back tol theiroperative osition and set as shown in Fig. 2. In this figure it Will-be seen that the column-stop corresponding 'to' letter space position forty has just been arrested by the denomination stop Acorresponding tothe decimal point, which brings letter-space position fort-y to the printing point, asshown in Fig. 2. The arrangement is such that when any column stop isset as shown in Fig. 21at acertain let` shown ter' space position they tabulator key Aand dei .nomination Stop eorresponding .to the dechimal point Will'bringthat letter space position of the peper to the Printing Pointlf will be obvious that ,by movin' .thedenolni nation stops one lway or the 051er any other one lorf said stops might be arranged to bring the point at which the column stop is set to the -printing point.

'In case the tabulator is used yfor writing 'amounts in UnitedStates money, the entire series of denomination stops might be moved two letter spaces toward the right-hand oi the operator, or toward the left as seen in Fig. l3,*With the result that when any tabulator key was depressed and the slun in United States money was written, the units of cents would come to the point on Vthe paper at which the column stop had been set'. As far as I am aware it is broadly new to pvlOYldc any means for bringing the paper in the machine into such relation with thc tabnlator stops as to enable the operator to set'said stops by direct'reference to the paper and wish certain of my claims di rected to this feature to be lunderstood as i and arrangement It will be understood, dff course, that the;

swinging rack is useful in itself aside from the setting of the stops: directly by vthe paper. `The rack bar 4,4 as shown in the present case is provided with a' scale corresponding to the platen scale 25 and the be set by reference to this scale if stops may preferred. Even when the stops are set in this manner the swinging rack feature makes the setting of the' stops a much more convenient opera-tion than it has usually been heretofore.

I contemplate a construction in which arms similar to the arms 45, support a bar on which are mount-ed the margin and line lock stops. ,This' construction is claimed specifically' in another a plicatin of'mine,

tiled June' 10th,'l907, l erial No. 378,271,

but. some ofthe claims of the present case' are intended to be broad enough lto cover said construction. In other words, some of the claims in the present case are intended to be broad enough to cover not, only tabulator stop mechanisnnbut also other forms of carriage stop mechanism.

It will be understood that my invention comprises features which are of use inde- [lendently-or. in other relations than those here shown, and also that various changes may be`made inl the details o-f construction my invention.
