Specification of Letters Patent.

Application filed November 9, 1912, Serial No. 730,350. Renewed January 28, 1915. Serial No. 4,964.

To all wk am it may concern-.-

Be it known that I, ARTH R W. SMITH, citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to tabulating mechanism.

One of the main objects of the invention is to provide denominational tabulating mechanism operative or effective during a portion only of the travel of the carriage and column selecting mechanism operative or effective only at another portion of the travel of the carriage.

- A further object of the invention is to provide key controlled tabulating mechanism including means operating automatically to enable the key or keys for such mechanism to operate in one instance for denominational selection and in another instance for column selection.

A still further object of my invention is to provide tabulator indicating means which are automatically shifted to bring different indices into use.

Another object of the invention is to provide tabulator mechanism which is operative at one time as a denominational selector and at another time as a column selector and to combine therewith tabulator indicating means which are automatically shifted as the tabulating mechanismis rendered e'fiective for one of said purposes instead of the other.

Another object of my invention is to provide a traveling tabulator stop which moves at a different rate of speed from the cartill another object of my invention is to provide a traveling tabulator stop, and means by which the speed of said stop may be varied relatively to that of the carriage.

A further object of my invention is to provide features of construction of the character specified which are applicable to existing forms of typewriting machines and to the tabulating mechanism embodied in such machines without modifying, or materially detail bottom plan view with parts in section, the view showing a part of the tabulator mechanism and the automatically actuated means for shifting the indicator. Fig. 3 is a fragmentary plan view of the machine with parts omitted and parts broken away. Fig. 4: is a horizontal sectional view of the machine with parts omitted, the section being taken on the line of Fig. l and looking in the direction of the arrows at said line. Fig. 5 is a detail fragmentary central transverse sectional view of one of the sprocket wheels and the adjustable means on which the wheel is mounted and by'which it may receive a bodily adjustment. Fig. 6 is a fragmentary detail front view with parts in section of the tabulator indicator and the means by which it is shifted. Figs.

'7. 8 and 9 are detail top plan views of three different sizes of driving sprocket wheels for the sprocket chain, which wheels are interchangeable on the driving shaft. Fig. 10 is a detail central sectional view of the sprocket wheel shown in Fig. -8 and the means by which it is detachably fixed to the driving shaft. Fig. 11 is a detail diagrammatic view showing the indicator and a modified arrangement of the shiftingmeans therefor. Fig. 12 is a face view of the indicator plate shown removed from its carrier. Fig. 13 is an enlarged detail fragmentary top plan view of the sprocket chain at the point of connection therewith of the traveling stop and showing a portion of the guide for the chain.

I have shown my invention in the presentinstance in a No. 11 Remington machine in which the invention may be readily emreference numeral 27.

gular levers 23.

bodied without modifying. or materially modifying the structural features of that machine as they now exist. It should be understood. however. that the invention may be embodied in various forms of typewrit-ing machines and that certain features may be employed without others.

The frame ofthe machine comprises a base 1. corner posts 2 and a top plate 3. A carriage -l (conventionally represented) is mounted on anti-friction balls or rollers 5 to travel from side to side of the machine over said top plate. The carriage carries a cylindrical .platen (3 and upwardly and rearwardly striking type bars 7 are adapted to strike against the front face of the platen.

Rearwardly extending bracket arms 8 are secured by screws 9 to the carriage and are connected at their rear ends to a column stop bar 10 provided with teeth 11 on the upper and lower sides thereof for the reception of column stops 12 in the interdental spaces between said teeth. Arms 13 are.pivoted at lto the carriage and are connected at their rear ends to a feed rack 15' which meshes with a feed pinion 16. This pinion is mounted on the forward end of an escapeme'nt wheel shaft 17 mounted to turn in a bearing 18 secured to the top plate of the machine. The rear end of the escapement wheel shaft carries an escapement wheel (not shown) with which the usual feed dog cooperates.

A series of tabulato'r keys 19 are provided with key stems 20 which are'guidcd in upper and lower guide plates 21 and 2; respec tively. Each key stem is operatively connected withan angular lever 23. the depend ing arm 2+ of which is connected to one end of a contractile spring whichhas its upposite end connected to the guide plate Each depending arm 24 is also connected to a rearwardly extending link 21') which is connected at its rear end to a tabulating stop device or member designated as a whole by the flach of these tabulating devices "27 is in the nature of a lever pivoted at 25' intermediate the ends thereof in a tabulator frame .29 fixed to the fran'ie of the machine. The upper end of each lever extends toward the front of the machine. as at 30, to form a denominath'mal stop which. when l'n'ojccted forwardly. is adapted to cooperate with one ofthe column stops 12. The denominational stops are projected through a guide comb 31 which is secured to the t'abulator frame 2'9. A universal rclc'ase bar 32 is connected at its ends to arms 33 which are pivoted at 34 on a pivot rod which also constitutes the pivot for the anrearwardly extending link is connected to each of the depending arms 33 and extends rcarwardly to a crank arm 36 to which it is pivoted. The crank arms 36 are fixed to and extend down- Wardly from a rock shaft 37 mounted for 'l'earwardly. thereby rocking the shaft.

pivotal movement in the base of the machine.

A crank arm 38 is also fixed to the rock shaft v This shaft is provided at its forward end with a pinion 4S and the rear end of this shaft has a bevel pinion 49 fixed thereto. In the normal positions of the parts the pinion 4 8 is arranged beneath the feed rack 15 of the machine and. out of mesh therewith. \Vhen. however. the frame 4; is rocked on its pivots the pinion 48 is thrown into mesh with the feed rack and the upward pressure -on the. feed rack is effective to disengage it from the feed pinion 16 to release the carriage from control of the escapement mechanism. .\t the same time the bevel pinion 49 is thrown into mesh with a cooperative bevel pinion 50. The pinion 50 is secured to the upper end of a shaft which turns the casing 51 and which is provided at its lower end with arms or blades which rotate within a fixed casing 52 secured to the top plate of the machine. Suitable material such as shot. for example. may be contained within the casing 52 so that the parts constitute a retarding device which is thrown into operation when the carriage is released from its esca 'iement mechanism and is moved from right to left under the power applied there to by the usual spring drum 53. This drum is connected to the carriage by means of a band 54 connected at one end to the drum and at its opposite end to an arm 55 fixed to the carriage.

It will be understood from the foregoing description that an actuation of the tabulator kc) l!) is effective to actuate the corresponding angular lever 23 t transmit move-, ment to the stop lever 27 which is connected therewith. thus moving the corresponding denominational stop 30 into the path of the column stops on the carriage. .\t the same time the universal release bar 3; is moved 3? and transmitting a forward rocking movement to the arm 39. which movement is effective to rock the frame 42. thus releasing the carriz'tge and throwing the car iage rctardcr into operation.

The parts thusfar described are the same as those embodied in the .\'o. 11 Remington machine except that in some instanccs the parts of the carriage construction have been conventionally represented. .\lorco\'er. the shape of the arm hasbecn slightly changed in order to acconnnmlatc itscl f to other parts ond away fronr the plate.

which have been introduced into'the machine. as will be hereinafter more fully explained.

A supporting plate 56 is fixed to the frame of the machine by supporting screws 57. These supporting screws are those usually employed in the machine for holding the key lever returning springs in place except that they are slightly modified to act as fastening devices for the supporting plate 56. Zach of the supporting screws 57 is threaded at its upper end where it is received in a tapped opening in a cross bar which forms part of the base of the machine. Zach screw is formed with a hexagonal or octagonal portion 5!) by which the screw may be threaded into the tapped opening in the cross bar. A spacing sleeve (30 surrounds the screw below the part 59 and against which the sleeve bears. The plate 56 has an opening through which the reduced threaded end 61 of the screw 57 extends. a nut (32 cooperating with the thread ed end (31 to secure the plate 56 in place. There are two of these screws 57. one at each side of the machine. and in addition to the usual .functions performed thereby they constitute means by which the supporting plate 56 is fixedly held in place. This supporting plate so constitutes a hearing or supporting member on which various parts of what may be termed the auxiliary tabulat-ing mechanism and the automatically actuated means for controlling the tabulator indicator are mounted. Thus. for example. the plate is tapped to receive a shouldered pivot screw 63 (Fig. i) which constitutes a pivot for a band or sprocket wheel (34. This wheel has a hub til which bears against the plate 56 and maintains the body portion of the wheel preferably spaced An endless band, which in the present instance is'in the nature of a sprocket chain 65. surrounds this sprocket wheel and also surrounds a secband or sprocket wheel 66.' The wheel (36 is mounted to turn on a pivot bearing (37 which is in the nature of an eccentric provided with a flange (38 (see Fig. 5) which overlaps the wheel 6 at the lower side thereof to hold the wheel 66 in place with the hub (39 thereof bearing against the supporting plate St). A screw it) extends through an eccentrically arranged opening in the bearing member or eccentric GT and is received in a tapped opening i'n-t he supporting plate 56. The head Tl of the screw is provided with a crank arm or linger piece 7; by which the screw may be turned to secure the eccentric in the rotative position to which it may be adjusted. It should be understood that the thickness of the eccentric 67 is such that when the head 71 is screwed up tight against it the screw will secure the eccentric against rotative movement but that the wheel (36 will be adapted to rotate freely on the eccentric. By this construction the eccentric tn' may he rotatively adjllsted'to any desired position on the screw To and secured by the screw in the rotative position to which it has been adjusted. Means are thus provided by which the wheel (it may be shifted bodily toward and away from the wheel (i-t in order to provide more or less slack in the sprocket chain ($5. as will hereinafter more clearly appear. The endless flexible band or sprocket chain also meshes with a driving sprocket wheel 73 which is detachably fixed to a driving shaft Tl by means which are clearly shownin Figs. 8 and 10. From these figures itwill. be observed that the upper face of the sprocket wheel 73 is provided with a circularly arranged series of radiating depressions 75. this portion of the wheel constituting in effect one section of a two-part clutch member. The other section of this clutch comprises a disk 76. the lower face of which is provided with circularly arranged radiating teeth 77 which are adapted to be received in the depressions T5 to effect an interlocking connection between the sprocket wheel 73 and the disk it This disk has a hub TS fixedly connected to the driving shaft by means of a pin T9. The-hub T8 is received in a bearing opening St) in the supporting plate 56. whereas the upper face of the disk To is adapted to bear against the lower face of the supporting plate .to prevent an upward displacement of the driving shaft 74 and the parts carried thereby. The

lower face of the driving wheel T3 is provided with a hub S1 against which a nut 5'! is adapted to bear to maintain the wheel 71, in such position that the teeth T7 will remain seated in the depressions T3. so that the driving shaft and wheel 73 are fixed to turn together. The out 9'. is received on the lower threaded end of the driving shaft and is provided with laterally projecting pins 83 which constitute a finger piece by which the nut may be turned to release the clutch. and

by which the nut when desired may be rc-' moved from the driving shaft to enable either of the wheels T3 or T3" shown in F gs. 7 and respectively. to be substituted for the wheel T3. The purpose of substituting one of these wheels for another will hereinafter more clearly appear.

The upper end of the driving shaft Tl extends through a bearing opening in the top plate of the machine and has a gear wheel 84 secured thereto. This gear has a long hub h l tapped to receive set screws 5 which hear at their inner ends against the driving shaft H to lixcdly connect the gear to the shaft. The lower end of this hub bears against the top plate to support the driving shaft and the parts carried thereby in place. The gear Si meshes with a rack St} which extends longitudinally of the carriage throughout the length thereof and is fixed by screws (Fig. 3) to the bracket arms 8 which support the column stop bar on the carriage. From an inspection of Fig. 3 it will be observed that the driving gear 84 and the driving sprocket 73 are of the same, or substantially the same;pitch so that with the employment of the sprocket wheel 73 a linear movement of the chain 65,. c0rresponding to the travel of the carriage, is effected by the movement-of the carriage.

A guide plate, designated as a whole by the reference numeral 87. is pivoted at 88 to the supportingplate 56 and extends at an inclination from its pivot to the driving sprocket, as shown in Fig. 4:, the guiding surface 89 extending in the general direction of the chain in its movement from one sprocket wheel 6.4 to the other sprocket wheel 66 but at a slight inclination to the chain. This guidemember is preferably made of sheet metal and is formed with a guiding surface 89 which extends at right angles from the body portion 90 of the guide. The body portion of the guide is bifurcated or slotted at 91 where it receives a shouldered thumb screw 92 which is threaded into a tapped opening in the plate 56. The shoulder 93 on the screw is adapted to bear against the body portion 90 of the guide and bind it against the suppmgting plate 6 in order to secure the guid e inany one of several positions to which it may be adjusted toward and from the a\is ot' the rock shaft 74. such adjustment of the guide being effected around its pivot 88. From an inspection of Fig. 1 it will be understood that when the guide 8'7 is maintained in place. the sprocket chain will be guided by the surface or'llange 89 and maintained againstmovement away from or out of mesh with the driving sprocket'73. \Vhen. however. the thumb screw 92 is released the guide may be moved away from the sprocket wheel. thereby enabling the sprocket chain to be deflected laterally away from the driving sprocket 73 and out of mesh therewith. lf necessary the eccentric 67 maybe turned to a llord suilicient slack in the chain to enablethis deflection of the chain out of mesh with the driving sprocket to be effected. It will be understood that when the chain is out of mesh with the driving sprocket the. chain'niay be moved longitudinally in order to efiect an adjustment of a traveling tabulator stop or contact device 94 which is car ried by the sprocket chain. The chain being disconnected from the driving sprocket in the manner described and a longitudinal movement of the chain being effected. it wil be understood that any suitable adjustment of the stop 91 relatively to the carriage may be ellected. From an inspection of-Fig. 13 it will be understood that the tabulator stop 94 is in the nature of a sheet metal plate which constitutes a part of one of the links of the endless chain and has an engaging or stop portion 95 and a projection 96 which overlaps a member 97 of an adjacent link. hen the parts are in the position shown in Fig. 13 the projection 96 will tend to resist a turning action of the stop 94 or a flexing of the chain at this point, as will hereinafter more clearly appear. This stop '94 is adapted to travel through a slot 98 'i'novement of the stop 9-1 when the latter is brought into cooperation with the stop members with which it co-acts. From an inspection of Fig. 13 it will be understood that the construction of the stop 94: is such that the projection 96 on the stop 9% cooperates with the member 97 of the adjacent link of the chain to resist a turning movement of the stop when the latter is brought into cooperation with the arresting means which cooperates therewith. The turning movement or iiexion of theadjacent link is resisted at this time by therear wall of the guide 99.

From an inspection of Fig. 3 it will be understood that those portions of the levers or stop devices 27 which constitute the denominational stops I50 arearranged at letter space intervals in the usual manner for denominational selection. The lower end portions of these levers 27, however, are fanned to effect a wider separation thereof, as indicated in Fig; 4. In the present instance the lower ends of the levers 27 may' be assumed to be separated at, say. four let-- ter space distances apart. These levers are received at their lower end portions in guide slots 101 in the supporting plate 56. said slots extending fore and aft of the machine to guide the lower ends of the levers 27 in the pivotal movement of said levers. The, plate 56 thus constitutes resisting means to prevent a lateral del'lectiol'i ot' the lovers when the tabulator stop 91' is brought into cooperation therewith. The lower engagingend portions of these levers are adapted to be mo\ ed *arwardly into the path of the traveling stop 94 and such engaging or a rresting portions of the levers may be regarded as stops, so that the levers constitute individually operable key controlled colun'm selecting stops and also constitute dentnninational stops.

From the foregoing description it will be understood that a depression of any of the tabulator keys 19 is effective to turn the corriage in the manner hereinbefore described.

The pivotal movement of the lever 21' thus elfeeted not only moves the denominational stop .30. formed as a part thereof. into the path of the column stops 12 on the carriage. but also moves the arresting portion at the lower end of the lever into the.path of the traveling stop 91. The construction and arrangement of the parts a re slu'htllat the column stops 1; are grouped at one end portion of. say. one-half of the colunm stop bar so that they are ell'ective for cooperation with the denomiuational stops at one portion only in the travel of the carriage: whereas the traveling stop H4 is not moved to a position where the column selecting stops are cooperative therewith until the carriage has reached another portion of its travel. where the denominational stops are no longer effective to coiiperate with the column stops 12. all as will hereinafter more clearly appear. It will thus be understood that at a given portion of the travel of the carriage, say. at the first half of its travel. an actuation of any of the tabulator keys 19 is elfectire to tlenominationally select in the various columnar lields determined by the adinstment of the column stops 12. and that, dllring. say. the second half of the travel of the carriage the column stops 1; are moved with the carriage beyond a position where the denominational stops can co-act therewith.

the geared connections between the carriage and said traveling stop) where an actuation of any of the tabulator ke vs is effective to interpose the lower end of the associated stop lever 27 in the path of the traveling stop SH. thus arresting the carriage through the cooperation of the stop lever and the traveling stop 94 in any one of several columnarfields determined by the particular tabulator key which has been actuated.

In order that the operator may at all times know whether the tabulator keys are effective for denominational or for column selecting work. I have provided a tabulator indicator and automatically actuated means by which said indicator may be shifted to bring one or another of two series of tabulator indices into view. depending on whether the keys are operative for denominational selection or for column selection. Thus from an inspection of Figs. 1 and 6, it will be observed that the front plate 102 is provided with an inclined portion 103 slotted transversely ofthe machine. as indicated at 101. to provide an elongated sight opening through which the tabnlator indices on a suitable indicator mav be displa ved to the view of the operator. A scale or index plate 105, which is shown in detail At this time. however. the traveling stop 91 has been brought to a position (by in Fig. 12. comprises in the present instance two series 106. 107 of index numerals. either of whichscries may he ln'o'ught into register with the sight opening 104. the other series at this time being hidden from the operators view beneath the body portion of the plate 103. The scale plate 105 is received in a sheet metal carrier 10$ which is turned over at its top and bottom edges. as indicated at 109. to receive the scale plate 105 and dctachably hold the latter in place. The carrier 109 is supported at its ends on levers 110 pivoted at 111 to the base of the machine and extending downwardly and rearwardly from their pivots. ()ne of these levers is connected at its rear end to a link 112 which in turn is detachablv connected at its rear end to a lever 113 of the first order. This lever 113 is pivotally mounted on the supporting platefit' by a headed shouldered screw pivot 114. the shoulder of which is adapted to bear against a disk 115. Intel-posed between the disk 11.3 and the supporting plate 56 is a leaf spring 116 which is bent to form a connecting portion at one end. as-.indicated at 117 in Fig. 4. The screw 114 passes through the connecting portion formed at the bent end of the spring and when the screw is tightened the end 117 of the spring is securely clamped between the disk and the supporting plate. although the lever 113 is loosely mounted to turn on the pivot screw between the head thereof and the disk 115. The free end of the spring 116 is bent to form an engaging portion 118 which, cooperates with the teeth l19-of a wheel 1:20 to provide a spring detent for the wheel. as will hereinafter more elearlv appear. The wheel 120 is mounted on a headed shouldered pivot screw 121 which is received at its threaded end in a tapped opening in the supporting plate. headed screw 12:2 projects laterally from the wheel 1:20 and the stem of the screw is received in a slot 123 formed in the lever 113 at the inner end portion thereof. The wheel 120 is shown in the present instance provided with six teeth and it is normally positioned, as indicated in Fig. 4. with one. of said teeth in the path of the traveling stop 94. During the movement of the carriage from right to left the tabulator stop 9-1 will bemoved in the direction of the arrow in Fig. 4. thereby bringing the stop into engagement with the real-most tooth of the wheel 120. This effects a turning of the wheel a single tooth space distance during the movement of the stop past the wheel. This movement of the wheel is effected against the pressure of the spring detent 116 andthe turning movement, of the wheel transmits its movement to the lever 113. thereby shifting the outer end of said lever toward the frontof the machine. This movement is elfective to turn the lever 110 to which the link is connected in order It will be understood that the indices contained between adjacent dividing lines 124 are adapted to register with one of the tabulator keys 19 so as to constitute an indicator therefor. \Vhen the indices 106, for example, are at the sight opening the indices between each pair of adjacent dividing lines 124 will register with one of the keys. As the parts are arranged in the present instance, and assuming the carriage is at the limit of its travel to the right, the denominational indices 106 will be exposed at the sight opening and the indices within each space on the. scale will be associated withthe corresponding key which they are intended to designate. Thus the decimal point will be arranged just in the rear of the first tabulator key to the left, whereas the numeral 1 indicating the units, will be in the rear of the second key and so on. When, however, the carriage reaches about midway. in the travel thereof the column stops will pass beyond a position where the denominational stops are cooperative therewith and the traveling tabulator stop 94 will be brought into coiiperation with the wheel 120 to turn it one step, or the distance between two teeth of the wheel. The effect of this movement is to actuate the lever 113, thereby shifting the indicator to bring the series of column selecting indices 107 into register with the sight opening and into register with the respective tabulator keys which the indices are intended to designate. as the wheel 120 has been turned in the manner described, the stop 94 is in a position to co-act with the lower ends of any of the levers 27 which may be projected to operativeposition. If, for example, the fourth tabulator key from the leftbe actuated, the lower end of the corresponding lever 27 will be moved into the path of the traveling stop 94 and the carriage will be released. As the carriage moves to the left the traveling stop 94 will be moved to the right until it has been arrested by the fourth lever 27, counting from the left, the stop passing the first three levers 27 without, being obstructed in its movement. The carriage will be ar rested therefore in the fourth columnar field determined by the actuation of the fourth tabulator key. A release of the depressed tabulator key 'reestablishes operative connection between the carriage and its escapement mechanism, the operator proceeds to write in the fourth column and when this is conpleted a tabulating operation may be effected to carry the carriage to the proper position to write in the next selected colum- As soon' portion of the travel of the carriage.

A clearer understanding of the invention and the purposes to be obtained thereby may he arrived at by considering the operation of the parts in connectionwith a blank of a specific character to be filled in with the aid of the tabulating mechanism, it being understood that "arious forms of blanks may be employed in connection with the mechanism but that the parts in the present instance are constructed, arranged and adjusted for use with a blank form such as is indicated,,for example, at A in Fig. 3.

In this'form there are provided six columns in which the manufacturers number,- style of the goods, a special number applied to the goods, the quantity thereof, a description of the goods and the date of delivery thereof may be written. These columns are indicated at a, b, c, (1, a and f. The column stops 12 having been adjusted as indicated in Fig. 3 to correspond to the positions of the columns where the items are to appear, the stop 94 having been properly adjusted, and the operator having moved the carriage to the right, will proceed at once to write the manufacturers number as 567 in the first column a. Anactuation of the decimal. key, (the same being indicated by the decimal mark on the indi ator) will bring the carriage to a position where the operator may proceed to write the word French or such other inscription as is to appear, in the second column b. The operator may then depress the tens of thousands key indicated by the index numeral 10,000 opposite the corresponding key. This enables the operator to write the special number 54035 in the third column 0. An operation of the tens key, indicated by its appropriate index mark, is effective to arrest the carriage to enable the operator to write the designation 20 under the heading Dozens in the fourth column d. An actuation of the decimal key will arrest the carriage in the position to fill in the proper inscription in the fifth column e under the heading Description In the present instance the term underwear describes the class of goods. After this term has been filled in the operator may depress the decimal key to enable column 7' under Delivery an automatic' actuation of the tabulator indicator will be effected, and at the time of completing the writing of the date the first five column stops 12 will be carried beyond the denomi national stops and the traveling stop 9-1 will have passed the wheel 120 and be in a position to coiiperate with any of the levers 27 which may be actuated. so that the parts are 110w in position for column selecting work. However, I have provided a sixth column stop 12 at the right-hand end of a series of column stops 12, and which column stop 12 is in the nature of a safety stop. The purpose of this stop is to insure a proper change of the automatically actuated tabulator indicator so as to be assured that the column selecting indices will be presented to the view of the operator before the tabulato'r keys can be operated for column selection. If the date be of an extent such as that indicated in the drawing, then the automatically operated indicator will be properly actuated before the completion of the date and the tabulator indicator will expose the column selecting indices before the writing of the date is finished. If. however; the date should occupy less space than that indicated in the drawings and the operator should complete the date before the carriage has arrived at a position to effect an automatic change in the tabulator indicator. then an operation of any of the first four or five tabulator keys would effect an interpositioning of the corresponding denominational stop in the path of the safety stop 12? to arrest the carriage and prevent its movement to a columnar field g to the printing point. This insures a change in the indicator being effected to present the column selecting indices to the view of the operator before the mechanism is capable of operation for column selecting work. If the safety stop 'should be brought into operation in the manner specified the carriage will still be positioned in the column f, although the tabulator indicator will be automatically changed to expose the column selecting indices. The operator may then proceed to select the desired columns and fill in the requisite numbers, for example, in thedesired columns under the proper headings. In the present instance the blank A contains indications at the heads of the next ten columns g of the sizes of the articles and corresponding indices are exposed at the sight opening 104. If, for example the order is for four dozen size 18 then the second tabulator key opposite the index numeral 18 will be depressed, ther'ebyarresting the carriage in the second column 9 where the numeral 1 may be. written. If

22 the order mcludes three dozen s1ze Y v 28 1 three. dozen size 40 and ten dozen size &) i ii, the fourth, seventh and ninth tabulator keys from the left will be successively actuated and the numerals 3 3 and 1O will be successively written in the respective columns determined by the actuation of said keys. It will be seen that the order contains ten dozen size dozen size 40 three dozen size 34 four dozen size 18 thus making a total ,three of twenty dozen as inscribed in the column (l of the blank. T heline having been completed the operator returns the carriage to the right. thereby moving the traveling stop 91- in a direction opposite that indicated by the arrow in Fig. 2, thus automatically actuating the indicator to expose the denominational indices instead of'the column selecting indices. The second and successive lines in the blank may be filled in in av like manner.

It will be seen that during, say, the first half of the travel of the carriage in each line of writing the tabulating mechanism is operative alone for denominational selection by the coiiperation of the denominational stops 30 with the column stops 12; and that at this time the denominational indices are exposed at the sight opening 101, whereas during. say, the second half of the travel of the carriage the tabulator mechanism will be operative for column selection alone and will be inoperative for denominational selection. At this time the tabulator indices 107 which aid in column selection are exposed at the sight opening 104 adjacent to the tabulator keys 19 which are now operative for column selection.

Should the character of the blank be such as to necessitate column selection at tlfe beginning of each line of writing and denominational selection at the last portion-of the travel of the carriage, this may be brought This is in order' the left-hand side of the series of stop levers QT and the link 11:? may be connected with the right-hand arm 110 instead otwith the corresponding arm at the left-hand side of the machine. 'lheeti'ect of this change in the.- disposition of the parts is to maintain the lowermost llldiccs 107 at the sight opening 104 during the first half of the travel of the carriage instead of at the last half of the travel of the carriage as in the previously described arrangement of the parts. 'hen the parts are arranged as shown in Fig. 11. the automatic shifting of the indi cator is not effected until the stop 9i has passed the series of stop levers 27 during, say. the first half of the travel of the carriage. During the first half of the travel of the carriage the operation of any of the levers 27 is effective to co-act with the stop 94 to arrest the carriage in the selected columnar field as determined by the particular tabulator key which has been actuated and which keys at this time are in the nature of column selecting keys. It will be understood that in these circun'istances the column stops 12 will he situated at the righthand end portion of the column stop bar instead oi at the left-hand endportion thereof so that they will not be brought into cooperative relation with the denominational stops during the first half of the travel of the carriage. But the column stop 1'2 will be brought into cooperative relation with a projected denominational stop after the stop SH has passed the stop levers '27 and has auton'iatically effected an actuation of the index scale to bring the denominational indices 106 into view at the sight opening 104. Moreover. it will be understood that by an adjustment ofthe stop 94 relatively to the carriage and by an adjustment of the column stops 12 to different positions along the column stop bar, the tabulator mechanism may be arranged to provide for denominational work throughout the extent of more or less of the travel of the carriage in each line of writing; and, of course. the number of columns in which denominational workmay be effected may be varied according to the number of column stops 12 employed.

I have provided means in the present instance whereby the width of each -column g7 selected by the column selecting mechanism may be varied. As shown in the present instance. with the use of the sprocket wheel 73. provision is made for writingas many as four characters in each of the separate columns t f A substitution of the larger sprocket wheel T3, shown in Fig. 7, for the wheel 73. makes provision for writing as many as three characters in each of the columns g, Whereas a substitution of the smaller sprocret wheel 73', shown in Fig. 9, for the wheel 73, provides for writingas many as five characters in each of the columns "g. These wheels, as previously pointed out, maybe substituted one for another by the means shown in Fig. 10 and the corresponding change in the width of each of the columns 1/ is provided for.

.\s hereinla-t'ore pointed out, the eccentric GT is eli'ective to afi'ord a bodily adjustment of the sprocket wheel 6 so that more or less slack may be provided in the sprocket chain (35. as may be required by the use of the different gears shown in Figs. T 8 and 9. Thus if the wheel T3 be employed instead of the wheel 73 an adjustment of the eccentric (31' will be required to shift the wheel 66 nearer the axis of the wheel (H in order to make provision for the employment of the larger sprocket wheel 73''. After the eccentric has been rotatively adjusted to the desired position it may be secured in this position by the screw T0 so as to maintain the chainsulliciently taut to assure its proper cooperation with the various sprocket wheels.

'In setting the parts according to the par-- ticular blank employed, the blank will be introduced into the machine. as shown in Fig. 3, and the carriage moved to a position where the tabulator mechanism has linished its operation as a denominational tabulator and is to begin its operation as a column selector. Thus in the present example the carriage will be moved to a position where the last written character in the column under the heading Delivery. is at the printing point. The sprocket chain will then be slackened to enable it to be disconnected from the driving wheel 73 or the -::lutch,ma v be released to enable the chain to be moved independently of the carriage. The chain may then be. moved longitudin ally to bring the stop 94 just to the right of the first ot' the column stop levers :27, counting from the left in Fig. l. The chain may then be rcengaged with the sprocket wheel 73 and the eccentric positioned to maintain the chain taut, or the clutch reengaged. If desired, an index mark may be employed on the supporting plate 56 to indicate the proper position of adjustment of the stop 94. After this adjustment has been attained in the manner set forth the operator may proceed to fill in the blanks, it being understood, of course, that the column stops 12 have been previously set according to the work to be performed through the cooperation of the denominational stops 30 with said column stops 12. In setting the stop 94. in register with the index mark on the plate. 56 in the manner pointed out above, it should be moved from left to right past the wheel 120 so as to shift the wheel and change the index. It will be understood that the spring detent maintains the wheel 120 in the rotative position to which it may be shifted around its pivot and is effective therefore to maintain the indicator in either of the two positions to which it may be shifted relatively to the sight opening 104:. lVhen the stop 9 L moves from left to right past the wheel 120, said stop shifts the indicator in one direction by If, on the other hand, the operator desiresv to employ the denominational stop mechanism to the exclusion of the column selecting mechanism, then the stop 94 may be adjusted to a position relatively to the carriage where it will not be brought into cooperative relation with the levers 27 or with the wheel 120 throughout the entire travel of the carriage. This may be readily done by moving the carriage to the extreme right, releasing the clutch which connects the driving wheel 73 with the driving shaft and moving the chain. longitudinally until the stop 94 is positioned to the right of the series of stop levers 27. The clutch may then be engaged but the travel of the stop 91L during the travel of the carriage will be such that it is never brought into cooperative relation with the stop levers 27 or with the wheel 120.

The tabulator'therefore as a column-selecting mechanism will be thrown out of use but will still be efiective for denominationa selection; A disconnection of the clutch by which the wheel 73 is connected to the driving shaft is in itself sufficient to render the mechanism inoperative as a column selector and to throw the automatically actuated -meahs for the indicator out of operation.

It will thus be seen that provision is made for the use of the tabulator mechanism, when desired, as a mere column selector which will afford a selection of any one of eleven columns under the control of-the ten tabu-- lator keys 19. These columns will occupy, when the wheel 73, for example, is in use, a space corresponding to 55 or more letter space positions in the travel of the carriage and the parts may bearranged to begin the columnar selection at any point in fthetravel of the carriage, depending on the relative adjustment between the stop 94 and the carriage. If, for example, the first of the series of columnar fields which may be selected with the aid of keysis to begin at 20, then the carriage will be moved to the po-. sition 20 as indicated'by the carriage scale. The chain will be released from conumns may be selected at will. During the carriage the second traveling stop 94 will trol of the driving sprocket and the stop 94 will be adjusted just to the right of the left-hand stop lever 27. The chain may then be re-connected with the driving sprocket and when the first column selecting key is depressed, the carriage will be arrested to write in the first column, beginning at the point 20 on the carriage scale, it being understood, of course, that at this time the column stops 12 and the safety stop 12 have been removed from the machine. Any one of nine succeeding columns arranged five letter space distances apart may be selected with the aid of the tabulator keys 19,

which at this time operate as column selecting keys.

, If desired, an additional stop corresponding with the stop 94 may be employed on the driving chain, which last mentionedstop will be brought into cooperative relation with the stop levers 27 after the first stop 94: has moved beyond or past said levers. By these means columns may be provided across the entire sheet and any of said colfirst half of the travel of the carriage the first traveling stop 94, will co-act with any of the levers 27 which may be actuated and during the second half of the. travel of the co-act with said. levers.- In these circumstances the character of the indices on the index plate will be modified so that both series of indices will be column designating indices, one series of which will be exposed 100 at the sight opening 101 during the first half of the travel of the carriage and the second series of which will accord with the headings of the columns which may be se lected at the second half of thetravel of" the carriage and an automatic actuation of the indicator will bring the second set of indices into view at thesight opening. in the manner hereinbefore described. lVhen the'tabulating mechanism is to'be 11 used exclusively as a denominational tabulator the stop 94 may be adjusted to a position where it will never come into contact with the wheel 120, as hereinbefore explained, or the link 112 may be disconnected 115 from the tubulator indicator so as to render the latter inoperative. In either event the tabulator indicator set'for denominational 111 ofthe indicator to maintain it against accidental displacement ineither of the positions to which it may be shifted.

- It will be understood from the foregoing description that the same key controlled devices 27 which are eliective at one period during the travel of the carriage as denominational stop devices, are effective during another period in the travel of the carriage as column selecting stops; that the same keys which control said devices 27 act in one case as denominational selecting keys and in the other case as column selecting keys; that the tabulator indicating mechanism' cooperative with said keys is automatically changed according to the purposes for which the keys are operative or effective, in one instance acting as denominational selecting keys and in the other instance as column selecting keys; that the construction is comparatively simple; that the means by which a column selection as well as a denominational selection may be effected and the means by which an automatic shifting of the tubulator. indices is obtained are in the nature of attachments which may be readily applied to existing forms of typewriting machines, such as the No. 11 Remington machine, without modifying, or materially modifying, the structural features of said machines as they now exist; that the construction is such that it may be employed for various characters of tabulating work, either as a denominational tabulator or as a column selector or as a column selector at one portion of the travel of the carriage and a denominational'selector at another portion of the travel of the carriage; that the construction lends itself readily to variation and arrangement of the parts in order to enable it to operate 'efl'ectively in connection with various styles of tabulatingwork; that various changes may be made in the construction and arrangement of the parts without departing from the spirit of my invention and that some of the parts may be used without others, depending on the nature of the work to be produced.
