To allen/110m it may concern.'

Be it lmown that L. GEORGE E. GRIFFIN, a citizen of the United States, residing in the borough of Brooklyn, `city of New York, in

'the county of Kings and State of New York,

lmechanism, known as a column skipper" or jumper, comprising-a set of stops carried by a rack on the carriage and set to correspond in number and position to the columns of the tabulation to be written; and

key-controlled means to release the carriage and cooperating with the column stops on the carriage'to arrest the czm'riage at a selected column position, which"r setting may involve the skipping of one ormore columns or column stops before the carriage is arv rested. i

The invention also provides, in combination with the column-selecting mechanism, a decimal tabulator comprising a set of stops on the carriage; and key-controlled stops c0- o'perating "with the carriage stops to arrest the carriage at a desired decimal position in the columnl to which the carriage has been brought by the column-selecting mechanism.

I provide a. tabulating mechanism, the carriage stops and key operated parts of which may be used, either as a column selecting apparatus, by means of which the carriage may be skipped to a desired column; or as a decimal stop mechanism by means of which the carriage may be jumped to a desired decimal position in a column. In the structure hereinafter described, the carriage stops are of two kinds, one or the other of which may he exclusively employed in connection with the key operated means according as to whether the mechanism is to be used as a i column .skippcr or selector, or as a decimal tabulator. Also the column-selecting and the decimal-sclecting features may be combined, and both kinds of carriage stops may be employed at the same time and be governed from a single set of keys. Each key may control some one colurnn -selectuig stop and also some one decimal tabulator stop. said key having the same movement, both in direction and degree for both ur-- pos. The keys each having a marking rom l, .2, 3, etc., to indicate the column tobe selected by the key when the key is operated as a column selecting key; and the kevs have also each a marking to indicate the decimal stop controlled from the key when the key is used as a decimal selecting key. A k'ey may be operated to bring the carriage to a selected column position, and the same or another of the keys, according to the decimal desired, may then be operated to jump the Y carriage from the selected column position to the desired decimal position in that column.

Another feature of the invention is to provide a mechanism in Which the columnselecting key operated parts are relieved of the weight of the stop device which coperates with a stop on the carriage in arresting the latter. The column selecting keys set certain devices so that the same, when set, may be struck and actuated by the carriage, and when so actuated by the carriage may operate the movable stop which is to arrest the carriage at the selected column.

Another feature of the invention is a universal or single stop controllo/l from each of the column selecting keys 0n the carriage and adapted to be moved into engagement with the carriage to arrest the latter in the different column positions, depending upon which column key is operated.

The first column stop key may be operated to give the carriage a column to column movement where no column skipping is desired, or in which any other key representing a column already passed may be repeatedly used for column to column advance of the carriage during the rest of the line.

Column-selecting stops adjustably mounted on the carriage rack comprisetappets of different lengths arranged to project progressively to different distances from the rack. Interponents, which may be in the form of pivoted arms or pawls, are mounted on a movable support, the interpon'ents arranged in a series which extends at right angles to the carriage rack and are projectable selectively by means of a series of key-actuated plungers into the path of said tappets. lVhen a selected interponent is projected by depressing the corresponding key, the carriage is released and runs forward until the tappet corresponding to the projected interponent strikes the latter and swings its support to project a counter-stop into the path of said tappet, and thereby brings the carriage to rest at the column position correspending to the actuated key. ln addition to the column-selecting stops on the carriage rrack, decimal stops may be placed on the rack and may be intercepted by the said fplungers. rllhus the carriage may be brought to any selected column position 'by actuating the corresponding ltey of the series, and then brought to the desired deci* mal position in the column by actuating the key corresponding to the desired decimal positiou.

Other objects and i'eatures tion Will presently appear.

Fig. l() is a detail perspective vieu1 similar to Fig. S except the parts are 'in normal position and the carriage rack is omitted. Fig. ll is a detail per- Spective View showing the connection of the. universal stop to the paivl carrying frame. Figl2 is a detail vien1 in front elevation showing the stop setting mecha ism atvthe time the same is engaged by one of the collps. power-driven carriage l', which is partlylyshown in Fig, l, and which carries the platen and other parts (not shown), is mounted in a Well known manner 'to have lonitudinal movement on a rail 2, supported in the .main frame 3 of the machine. The carriage is driven from the usual spring drum 3' shown in dotted lines (Fig. l), and its letter feed movement is controlled by an escapement mechanism comprising a pinion e (see ig. 2)- Which engages the escspement rack 5 on the carriage. The escapene'nt racjl is supported from the carl-rlag by means of arms 6 pivoted at 7, one

ment with the pinion 4. One of the arms 6 I is extended beyond the pivot 7 to carry a release key (not shown) for rocking the arm to lift the rack out ot engagement with the pinion, so that the carriage may be moved free of the control of the escapement mechl'llSm.

llhe present machine is especially adapted for tabulating Work, and to this end comprises:` a mechanism for releasing the carriage from f the escapement Wheel so that the carriage may be thrown from column to column by the drum spring; a system of stops adjustably set on the carriage of the machine according to the column positions in the-talfbulation; and a system of key con- Y trolled stop plunger-s coperating with the fixed adjustable stops on the carriageto 'eelectahd stop the carriage at a desired column or decimal position in a column when the carriage is released from the escapement wheel.

T he column stops are shown at 10, engag ing the teeth of airaclt A1l which is attached by means or brackets l2 (see Fig. 9) to the carriage frame, so as to be movable with the carriage. The rack 1l has an upper and lower toothed tace, and the stops 10 are shaped so as to engage the rack above and below, and to tit between the teeth of the rack so as to be held by 'the latter against displacement. To position the stops, the same are forced onto the rack from the rear. The column stops 10, (see Fig. 3) are shown tappets ci' different lengths, the first tappet being shown as the shortest, and the length of the tappets progressively increasing from left to right.

For engaging any particular stop or tappet to arrest the carriage at the desired column, there is mounted in the tabulator frame 13 secured to the mainl frame,-a series of vertically movable plungers 14, each of which at its lower end engages with one of a number of keys 15 pivoted at 1G to the main frame and comprising a linger-piece 17' in. the keyboard. rlhe finger-pieces 17 are each marked from No. l to No. 10, from left to right. The plungers le, near their upper ends, have each a forwardly extending arm 18 (see Figs. 3, 6 and 10) and each the plunger teeth LMO (see Figs. 3 and 3.0)`

may be alined perpcndicularly to the line of increment of the rack 1l. The distance of the teeth Q0 irom the rack 1l, therefore, in' creases for each succeeding column plunger,

and this increase in distance. corresponds to the increase in length of the column stops 10.

The column stop representing the irst column is of sutlicient length to extend'into alweer the plane of the tooth 20 of the first plunger, the stop of the second column is of suffcient length to extend into the plane of the tooth 20 of the second plunger, etc. Each,of the plunger teeth 20 forms a column-selecting device to coperate with one of afseries of spring pawls or interponents 21'so that when any particular plunger is thrown up by its appropriate key l5, it engages its spring pawl 21 and forces the latter into the ath of all the column stops 10 which are ofpsuflicient length to reach from the rack to the plane of the pawl so lifted. The interponent 21 thus operated is therefore presently engaged by a column stop 10 and acts to arrest the carriage.

The pawls 21 are mounted to swing independently of one another on a rod 22 as a pivot. The rod 22 is carried by a plate 23 on a bracket 25 secured to the tabulator frame 13. There is attached to each pawl 21 one end of a coil spring 26, the other end of which is attached to the bracket 25, whereby each of the pawls is held down against its respective plunger tooth 20 and is returned to normal position after being operated.

The plate 23, on Whichthe pawls are pivoted, is not rigid with the bracket 25, but is carried on or formed with a sleeve 27 supported. on a pin 24 in the bracket, so that the plate 23 with the pawls may swing bodily on the pin 24 as a pivot when a stop 10 driven by the carriage strikes any pawl. The sleeve 27 also carries an arm 28, the end of which engages in a hole 29 in a universal plunger 30.

when lifted, its 1 cal movement in the tabulator frame 13, and per end enters the path of movement of th same stop 10, which by means of the pawl has thus moved the plunger 30. Vvlhen, therefore, upon operation of one of the plungers 14, a pawl 21 is lifted and is struck by a column stop 10, the pawl so struck is forced back, and swings the plate 23 on its pivot 24, causing the arm 28 and the universal plunger 30 to be lifted in front of the stop. When this stop 10 has moved with the pawl a sufficient distance7 it strikes the plunger 30 (see Fig. 12) 'which it itself has lifted, and thus arrests themovement of the carriage. The plunger 30 therefore acts to lstop the carriage no matter what plunger 14 is operated. It will be noted that the plunger 30 is not moved by the keys 15, but is operated by the force of the moving carriage. As the' burden of stopping the carriage therefore does not fall upon the key-operated pawls 21, these latter may be light and small, and are not subject to injury or appreciable wear. The plunger 30 on the other hand, not being operated from the keys, may be as heavy `and substantial as esired. y The universal plunger 30 moves ina guide plunger 30 is mounted to have verti- 31 on the tabulator fr'a'me. It is held normally depressed, and is returned to normal position by a coil spring 32. The particular pawl 21 which was lifted, is swung down by its spring 26 as soon as the column key is released, the ends of the pawls 21 being so shaped as to be readily disengaged from the column stops. When the operated pawl is thus released, the spring 32vreturns the universal plunger, the latter, by engagement with the arm 28, returning the plate 23 and the pawls 21 to the position from which they were forced by the impact of the carriage stop.

Simultaneously with the operation of any plunger 14. the carriage is released from the escapement rack in order that it may be thrown by the spring drum 3a to the column position determined by the particular plunger operated. The means for releasing the carriage is well known, and is as follows: Each plunger has a shoulder or tooth 34 which projects below a universal bar 35 carried on arms 36 fast to a rock shaft 37. Also fast to shaft 37 is an arm 38 connected by a link 39 to a lever 40 pivoted at 41 to the main frame. On the end of the lever 41 is a bearing pin 42 for the roller 8 on which the carriage escapement rack 5 rests. lVhen therefore any plunger 14 is lifted by its key lever 15 the tooth or arm 34 on that plunger engages the universal bar 35 to rock the shaft 37. and through arm 38, link 39, and lever 40. to lift the roller 8 with the rack, so as to disengage the latter from the escapement pinion 4. A stop bar 43 determines both the upward and downward movement of any plunger 14 which may be operated. A coil spring 44 on the rock shaft 37 returns the latter, and all the parts connected thereto, to normal position when the key 15 is released. The spring 44, acting through the universal bar 35, may serve to return the plungers to normal position, and the plungers on returning to normal position will return the keys to normal position. lVhen the key is released and the spring 44 acts, the rack 5 falls back again into engagement with the escapement pinion, and the machine is ready for letter feed at the new column.

In the operation of the invention as above described, the keys 15 act as column stop keys, any one of which may be depressed, and the carriage thereby released and caused to jump to the column position controlled by the particular key operated. If, for instance, the key N o. 5 is depressed, the No. 5 plunger 14 and the No. 5 pawl 21 will be operated. The No. 5 pawl 21 is so far from the rack 11 that the first four column stops 10 cannot reach it, and consequently pass by it, as the carriage is impelled to the left by the drum spring. The No. 5 stop 10, however, is long enough to reach the No. 5 pawl 21, and on striking it causes the universal plunger 30 to be thrown up to intercept the No. 5 col umn stop 1,0 and thereby stop the carriage. The No. 5 key l5 is then releasedto bring theca-rriage again under the control of the escapement mechanism, and the parts being returned to normal position by' their` several springs, the letters or other characters in the column are written in` the usual manner. lf thereafter, it is desired to' jump from column No. 5 to column No. 7, for instance, the column No. 7 key is depressed. lf, however, column No. G is the next column desired, the column No. G key may he depressed, or any of the keys of the previous columns may be depressed in lieu thereof, because the column No. @stop 10, being long enough to engage the column No. (3 pawl 2l, must necessarily engage any operated awl 2l which is nearer the rack il than the llo. 6 pawl. lt follows therefore that where no column 1s to be lskipped the column No. l key l5 may be used -for every column advance of the carriage throughout the line; or any other key may be repeatedly used which represents a column already reached by the carriage,

The plungers i4 have been described in connection with the column stops l() and with certain other parts going to make up a lcolumn skipping' mechanism. The plungers 14 are, however, adapted to subserve another and different purpose. rlhey are adapted to serve as the ,decirnal. stop pliingers or counter-stops of a decimal tabulator. lll/'hen the machine is to be used in the latter capacity, the column stops l0 may be discarded, and a set of stops 45, such as shown in Fig.. 4, employed instead ot the stops 10. The' stops 45 engage the rack l1 in the same manner as the stops l0. The stops 45 are, however, all of the saine length and do not extend beyond the rack ll in such manner as te engage anyo the pawls 2l. They project somewhat below 'the rack, so that whenever a plunger 14 is elevated, the upper end 46 of the plunger is projected into the path of the stops 45 to torma counter-stop for said stops. lllhen a plunger i4 is thus operated, and the carriage is released and moves to the leit with the stops 45, the lirst stop 45, to reach the bank of plunger stops 14, 4engages that plunger which has been ele- \'ated,' and so arrests the carriage. `rlhc plungers 14,:1re spaced one Jtrom the other the regular letter feedv distance, so that'each plunger 14'1`nay represent a decimal position in the column. The plunger 14 to the extreme left represents the decimal point position andthose to the right of it, the position for the unil, the ten, the hundred etc. According, therefore, to which of the keys 15' is operated, the carriage will he arrested by a stop 45 at some one selected decimal position in the next column. The key ends 7,in addition to having a column marktiona Linnea@ ing for use in 4connection with the column stops l0, have also adecimal marking (see Fig. 6) for use in connection with the stops 45. lllhen only the stops 10 are used, the ends 46 of the plungers 14 have no funcand in order that these ends 46 may not engage the stops l() and thus prevent column skipping, the stops l() are cutaway as at 48 to form openings through which the end 46 of the elevated pluiger 14 may freely pass during the movement of the carriage. W henonly the stops 45 are employed, the plunger arms 18 and pawls 21 have no function. lt true. that every time a plunger is operated, there is also operated a pawl 2l. The stops 45 do not however reach the pawl so operated, and consequently-the universal plunger 30 is not lifted at such times.

rl`he mechanism has beenedescribed as a column skipper and as a decimal tabulator. lt may be operated to combine both these functions. ln other words, the carriage may not only be jumped to any predetermined column position by means of the key having the suitable column number, but it may thereafter be jumped-from the said predetermined column positionto any desired decimal position in fthe column by means oi the key with theY proper decimal number. forms of stops are used. rllhe markings en the scale 50 (see lfipg. 3) are ten to the inclr 'ber of points to tne left of the stop 45 for that column, to permit the stop 10 to engage its puwl 30 hefoe the stop 45 reaches the position of the extreme right hand plunger 14. -The stop 10 will therefore arrest thev carriage with the stop 45 in such position that thereafter aniv of the plungers may be selected to cooperate with the stop 45 in determining the decimal stopping position of the carriage for that column. ln Fie'. 3 the universal i'ilunger 30 is shown in alinemeit with the decimal p'oint plunger stop terminal 4o. tha s to say, nine points to the lett of the eXtreme right hand plunger 14. stop 45 used in conjunction with a stop if.) should therefore be positioned at least nine points to the right of the latter stop. Of course, where the matter to be written such that the higher decimal positionsV are not needed, then the distance between the stops i0 and 45 may he. accordingly reduced'.

`Wheu the mechanism is used as a combined column-skipper and decimal tabulator, the decimal stops 45 are only used at certain of the columns for which the col umn-selecting stops lOare set, as for example, one or two of the columns at the n such use of the machine, hoth and throw the universal plunger'A right-hand side of the Work-sheet. As the preceding column stops 10 therefore have no associated decimal stops 45, they may perform their normal functions of columnselecting devices. In other words, when the two sets of stops are combined, the keys 15 may be selectively operated to bring the carriage by a single movement to any columnar position to the left of or including the first column with which a decimal stopy is used. The same or a second key l5 may then be operated to bring the carriage to the required decimal position in the column. Obviously the decimal stops 45 might also be used for columns at the right or intermediate positionson the work-sheet without interfering with the normal action of the stops l0 as column-selecting devices for other columns 'where the stops 45 are omitted.

This invention is of particular advantage in machines with carriages taking a very wide work-sheet. On such sheets, such as certain vtypes of insurance reports, it is sometimes desirable to `group ordinary description in certain columnsnear the left of the work-sheet, and valuations in one or two at the right of the sheet. These valuations should be so positioned that they may be footed, and they are most easily so positioned by means of a decimal tabulator. For such Work therefore, a column selector is equired over the first part'of the run of t e typewriter carriage, while a decimal tabulator is re uired over the end portion of the travel o? the carriage.AA The present invention meets such a requirement with a single set of keys.

Where the two stops are used, two key operations are seen to be sometimes necessary, the first by a key to select the column, and the second by a key to select the decimal position in the column. One operation of a column key will not: however suffice to cause the carriage 'to ...skip a column for which there is a stop 45 on the rack 1l, because although the stop 10 of the column to be skipped will, by virtue'of the opening 48 pass the end 46 of the plunger operated, yet the stop 45101? the column to be skipped will not pass the end 46 of the operated plunger, but will en age that plun er and stop the carriage. pon a secon operation of the selected column stop ke the carriage will pass to the next column. If this next column is the selected column, the carriage will be arrested there by the universal plunger 30; or iJE not the selected column, then by the stop 45 of that column, in which latter event the selected column key is again operated, until in this manner the carriage is finally brought to the proper column.

The sto s 10 and 45 have shoulders 51 behind whit the scale plate 50 rests (sce 1), in such manner as to lock the stops on the rack ll. The scale is carried on arms 52 pivoted at 53 to brackets 54 carried by the rack ll, so that the scale may be swung up to permit of the positioning of the stops.

he structure'hereinshown and described Iis susceptible of a variety of modifications within the scope of the invention. The form of the stops, the arrangement of the stops, and the stop-operating mechanism may all be modified by one skilled in the art to meet any particular requirements. The most important feature of the invention is the adaptability of the mechanism to both column skipping and decimal tabulating purposes.
