Patented Sept. 10, 1907.

To all whom it may concern:

Bo it known that I, CHARLES H. SHEPARD, a citizen of he United Statcs, and a. resident of the borough of Brooklyn, city of New York, in the county of Kings and Statc of New York, have invented certain new and useful Type-Writing Machines, of which the following is a specification. i

This invcntion relates to tabulating mechanisms for volition is to provide a tabulsting mechanism co1npris-' ing a few simple ports compactly arranged upon the top plate of a typowriting machine, and having at the forward part of the top plste convenient finger-piece for controlling both the den minatiomdetcrmining mcch' anism and thc carriage releasing deviccs.

Othcr objects will hereinafter appear.

My invention consists in certain combinations of dc vices, features of construction and arrangements of partsnll as will be fully hereinafter set forth and par ticularly pointed out in the appended claims.

In the accompanying drawings, Figure l is a side olevation, partly in scction, of a Remington No. 6 typewriting machine, showing my improvements applied therzto, Fig. 2 is a plan of the upper portion of the machine. Fig. 3 is a front elevation of a portion of the tabuleting mechanism, the parts being shown in normal position. Fig. 4 is a view similar to Fig. 3, but showjustcd to thc'hnndrcds position and the carriage feeding rack as released from its pinion. Fig. 5 is a plan of the denomination stop, the slidoway therefor, and a cam whcrchy said step is actuated, the parts being shown in normal position. Fig. 6 is a front clcvation of the parts shown at Fig. 5. Fig. 7 is a view similar to Fig. 5, but showing the adjustment of the denomination stop which is cll'octcd by a movement of the finger piece to the position shown at Fig. 4. Fig. 8 is a side elevation of the parts shown at Fig. 7 Fig. 9 is a rear view of a bracket which is fixed upon Lhc front portion of the top plan of the machine, for supporting certain of he moving parts. Fig. i0 is a pcrspcctive view of a rack and imlcx forming part ofthe denomination slop incchouism. Fig. 11 is a pcrspccfive View of a column siop rack and its appurtenances. Fig, 12 shows details of a cam plate and gear. Fig. 13 is a cross section of a co? In the sevcrnl views, portions of the machinc arc omitted or hrekcn :1 way to more clearly rlisciosc ihc in vcntion, and similar purl-s arc dcrignalcd by similar numerals of reference,

The framework of the machinc compriscs n hnsc 1. comer posts 2 and iopplatc 3. A plains 4 is jonrnalcd in a frame 5, which travcls across said in]! plnlc,

said frsme having a roll (3 to run upon a shift. mil 7, and

being connected in rcsr at 8 by a rleuhlc hinge to u truck 9, which is provided with guide rolls 10 running upon a fixed rail 1]. The truck is connectcd by a roarwaxdly extending arm 12 to a slccve 13, which slidcs upon a third rail 14. The carriage as a whole is propelled by a spriug harrcl 15, which is connected by a ssrap 3G and arm 17 to the truck 9. The letter iced mechanism comprises a rack 18; fixccl upon arms 19, which are hinged at 201.0 the truck, and also a pinion 2i will] which said rack is in mesh hut from which it may he liftcd by a swinging movcmcnt upon the hinge 20. The pinion is suitably connected 1.0 an cscapement wheel 22. Thc type imprcssions are made by types 23, carried upon pivoted balls; 24, which arc connected hy rods 25 lo levers 26, having keys 27. Bencath the ho lcvcrs is arranged a transucrsc universal 7 0 bar 28, hung by rods 29 upon branches 30 of a (log rocker frame 31, which is pix-o1 erl at 32 in a brackct 33, and carries both a locding dog 34 and a dctent dog 35, and is also provided with a rcturuing spring 36. As the parts shove montiom-(l are in common use in said Remington machine, itis not deemed necessary to do scribe them more fully.

The tabulating mechanism comprises a hack 3?, arranged at the front of the top plate, a pinion 38 in mesh with said rack, a rcarwnrdly extending shaft 39 upon which said pinion is fixed, above] pinion 49 secured upon the rear 0nd of said shalt, a hovel gear or scgmcnt 41 in mesh with said bcvcl pinion, a can; plate 42 fixed to said hcvcl gear, a (lcnomination stop 43 controlled by said cam plate, and a. column locating step 44 a1'- ranged upon the truck or carriage.

The rock 3?, which cxtcnds horizontally and parallel with the run of the carriage, is slidably supported upon a fixed bracket 45, by means of forwardly projecting screw studs 46 and 47, (.hc furmcr oi which works in a. slot 48, and thc latlcr in a slot 49, said slots being formed in suirl bracket and cxlcnding longitudinally thereof, whcrchy snidrack is cnuhlcd to move cndwisc in a right linc. 'lo cffccl this movcmcnr, a handle 50 is pmvidcd l'nrwmdly of and paralicl with the rack, and having a fingcr piccc or key 5; at ils righi-hand end. Said handle is PlVUlUll by a hill; 52 iii its lciL-lmnd end (see Fig. 2} upon the rack slud 47.

Thc shaft 39, which carrics ihc pinion 38 at. ifs forwanl cm], is hm'izmnully jnnrnnlcd in from and rear homing plcccs 53 and 54, lhc iormcr of which is sccurcd upon thc lop philc by screws 55, which also pass down ihrough ears 56 and 57 hirmcd upon the hraclict 45 and .nval'l'gcd hcnculh the lwzirin g 53, whcrchy both the lug m] the hmcket' nrclsm-nred upon the top-plate. The bracket 45 is provid'n'il however, with on additional fastening screw 58. fifhc rear lug or hearing 54 is fastened by scrowsfiil.

. position shown ip dotted lines at Fig. 6, to a position The hcvcl pinion 40 curried at the rear mid of the shaft 559, incshcs with u toothed Btgliltnt 4], which is pivoted upon u vertical stud (it! (see Figs. ti and 12), which has n shoulder til, and whose lower end 62 is tapp d into the top plate, The hub of the segment is designated as [S3, and is formed with a bore large enough to rcccivc a hub (34 plUYlllOtl upon the cam plate 42. the bore of the cam plate lmh being adapted to fit upon the sl ud tit! and the two hubs being forced or otherwise secured rigidly togcthcr, so that tlf train plate and segment may lll l\t' as one piece. A cup s row (55 is tapp d into the upper end of the stud. to prevent the plate and The cam plate is horizontally in ranuctL and providcd with an eccentric slot tit; {see Figs, 5 and T), and also with a working edge or face I57, which is parall l with said slol. At its inncr cud said slot has a short stroight cum portion tits.

Working in thislot to, 68, is a vertical pin 69, which is fixed in and projcctsupwardly from a stop carrier 70, the latter b ing arrangcd beneath the cum plate and fitted to slide longitudinally in a box or trough 7], the said denomination stop 43 being formed integrally with said carrier and projecting upwardly therefrom] in position to be engaged by the working edge 67 of the cam 42, the engaging face of said stop being beveled to [it said edge, 33 illustrated clearly at Fig. 7. The box 7] extends in a dirctiou parallel with the run of the carriage and is fastened to the top plate by one or more screws 72. The box is constructed with parallel sides 73, between which is placed a long block 74, forming the bottom of the box (see Fig. 8), said sides and block being fastened together by horizontal rivets The block has parallel inclined faces 76, which match correspondingly inclined faces 77, formed upon the stop carrier, so that by an cndwise movement of the stop carrier, it may he lifted or rammed up from the normal rom from lifting.

where the nose. of the carrier may ride upon the horizontal surface 78 of the block and the heel of the can ricr may ride upon a horizontal surface 79 also formed upon said block. In the position shown at Fig. 6, the stop 43 is below the path of the colurr n stops 44 upon the carriage; but at theinitial movement of the cum plate 42, the stop carrier is forced endwise by the straight portion 68 of thccnm plate slot,and during said cndwise motion is forced upwardly by the inclined faces 76, 77, thereby being projected into the path of said column stops.

The extent of movement of thc carrier 70 to the right after the dcscribod lifting movement thcrcof dcpcnds upon the extent of rotation of the cam 42, and this in turn depends upon tlieaumunt of rotation imparted to thc shaft 39 by the rack IiT when the latter is slid to the right by the finger piece 5!. 4

To facilitate the positioningof thcsaid denomination stop. an index 80 is sccurcd upon thc stud 4ti(lig,ltl) and ascrii-sofgraduat ions is provided upon an inclined plati- HI which is formed integrally upon the bracket 45 at lllt' righthand t'lltl thcrcof. Divisions are placed upon said scale at such int rvals that a. movcnn-nt of l the index from ourdivision to the next col'i'cspolnls' with the movcmcnt of llll' denomination stop 13* thri ugh nu interval 1 ual to a letter-feeding movement of Ihc ciirriagc. 'l'hc said sczilc divisions, beginning I at th lcft, arc dI-sigmttcd respectiv ly as "l", l

10". 100", 1000", 10,000K 190,000". mi 1,000,000; and when the pointcu tit) stands opposite any of said gruduattions, the dcnominution stop is in position for arrosting thc carriage at the proper point for beginning the writing of a number having rhiindi outed denomination.

The hub 52 of the handle 50 is pivoted upon thcstud 7 so that the handle may be depressed for the purpose of swinging downwardly L111 arm 82, which has a forwardly projecting pin tlii working in t1 longitudinal slot. 8 1 formed in said arm, said slot having a working face or edge 85, wronged at such an inclination that a uniform downward movement of the lever may impart a. uniform nmvemeut lo the arm H2 irrespective of the longitudinal position of the lmcr. in other words, a given downward throw of the lever, when it is adjusted to the extreme right will impart the some extent of downward movement to the arm 52 as when the lever is adjusted to the extreme left notwithstanding that there is it change of relative positions between the pivot 47 of the lever and the pin 83 This is due to the fact that there is a lost motion which occurs between the inclined face 85 of the slot in the lever and the pin 83 when the lever is in the right-hand position as indicated in Fig. 3. It will thus be seen that the gradual inclination of the edge 85 compensates for the different positions of the lever in its adjustment from left to right or vice versa and that the change of leveruge on the pin 83 is compensated for in this way and a uniform motion is imparted thereto, Said arm 82 is fired upon the forward end of a rock shaft 86, which extends parallel with the shaft 39 and is journaled ttt its forward end in the lug 53, and at its rear end in the hen-mg 54. Upon said rear end is carried an upwardly projecting rocker arm 87, to the upper end of which is connected by a screw 88, the left-hand end of a thrust link 89, whose right-hand end extends downwardly and is pivoted at to the depending arm 91 of a hell crank, which is pivoted at 92 upon a bracket 93 fixed upon the forward end of a bracket 94, which usually supports both the carriage feeding pinion 21 and the cscapmuent wheel 22. The horizontal arm 55 of snid bell cruuk carries atits free end a roll 91L whose normal position 'is just be neath the carriage feeding rack l8, so that an inward thrust of the link 89 may, by rocking the, hell crank lift the rack out of mesh with the pinion.

The column stops 44 are adjustably mounted upon it horizontal rack or bar which is designated generally as U7, and upon the lower face of which are cut teeth 98. The upper portion of the rack is provided with opposite (love-tail grooves 9!) whereby the ruck is duluchahly supported at one end upon it bracket It)", and ut the other end upon above mentioned arm 12 formed upon the carriage truck. The bracket ltlt) is dovc'tailcd at ltll to match the grooves on the rack, and is secured upon the carriage by scrcvvs ltlZ, The arm I2 is similarly dovoduilod at ltlil. At its left-hand end the rack is provided with :1 handle ltl'l, whereby it may be drawn outwardly :uld discugagcd from the carriage whereupon the column stops may be arranged at any desired intervals alone said rack. 'lhc latter miry lhon he relnountcd upon the iarrii uc, a vertical stop plate I05 boiuu lixod upon the farther side of the arm l2. for the rack to abut against uhcn it is slid ondwise to position. The rack is provided with a central longituother.

50 which corresponds 20 Fig. ,4. Then the button 51 is pushed downwardly to dinel slot or opening lUG. to receive upverdly proiecl; l in line with the slidoway 71, so that the pros-sure oi the ing centrally arranged, opposite fingers l0? provided upon the column stops 44, said lingers being separated a t 108 to enable them t he sprung slightly towards each The slot lllli is formed with downwardiyand inwardly converging inrlinoil Walls for coaetion with the lingers, the narrow portion of the said slot communicating with the notches between the rack teeth 98, and th tins of the spring fingers being preferably rounded 10 and arranged close together so that they may be inserted tinnigh u notcli upwurdiy into the opening 106 whereupon the stop may he pushed to its seat, the tingers their d! verging or springing outwardly to fit the converging mil-ts of said opening, so as to sustain the (olin in stop The fing rs are prelerably formed inletime stop rock pulled out of file machine, WllUllllPUl] the stops 44 are inserted at any desired lIIl-UTVlLlS between tlie ieoth 98 of the rack The latter is then remounted trpon the carriage and pushed into position against the stop plate 105; whereupon the paper carn'age is pushed to the righthand of the machine and then the paper to be written 011 inserted in the: usual manner. By means of the bptton 5 and the handle 50 the rack 37 is drawn towards t l 1e right, until the in dex 80 registers with a'division upon the scale 81 ('orresponding with the denomination of tlie'numbor to be written. If the denomination is hundreds, the rack is moved until the index occupies the position shown at Fig. 4. During this movement, the pinion 33, shall 39 and bevel pinion 40 are rotated, time him parting a rotary movement. to the bevel gear 41 and earn-plate 42. Said own-plate acts upon the pin 69, which projects upwardly from the denomination stop carrier, and forces both the pin and the carrier towards the right, or in a directionopposito to the letter lending movements of the paper garriage. At the iniiiel portion of the sliding movement the denomination stop carrier is elevated by the co-eetion of the inclined loco; 76 and 7 7 whereby the denomination stop =13 is brought into position for engagement with a column stop. It

ill be perceived that this upward movement of the @op 43 is in a direction transverse to the run of the carri e. As the rotary movement of the cam plate continues, the stop carrie r 70 is slid towards the right E Ennlll the position illustrated at Figs. 2 and 8 is reached, the position ol the index 80, at

vibrate the lever and the arm 82, \vliereb the shaft 86 is rocked and the arm 87 vibrated pushing The link 89 to the right, swinging the hell crank arm 9] rtndelw vating the arm 95 and roll 96, and lifting the carriage #15 ca nhplato, the pivot of the latter being substantially Carriage and stop against the cam plate is upplic-(l in a suhstantially radial direction, and hence is ineffective to rotate the plate upon its pivot. The carriage being thus arrested, the button 51 is permitted to rise under [he influence of a. returning spring 109 roiled about the shaft 86, and an independent spring 111 on the hub 52 the link 89 being at the some time drawn to the left by thrrookcr arm 8?, and the carriage feeding rack 18 being hence permitted to drop into rongagenu-nt with its pinion. It will be understood that at this time the carriage is still detained by the denomination stop 43, and hence there is no danger of u nus-stop or spurious feeding movement of the carriage Preferably the parts are no proportioned that the carriage is arrested at :1. point slightly to the right of its proper printing posliion, so that when subsequent disengagement telqos pleoe between the denomination stop and the carriage stop, there may be a slight drop" of the carriage, whereby it is brought to its proper printing position. Aftcr the upward movement of the finger pieee ill, the lultor is allowed to return to its normal posllion to the loll. through the pinion 38 and rack 37, under the inlluoucu of n npring l'lll (oiled about the shaft 39, which also returns the segment 41 and cam plate 42 to nor null position During Hilltl return of the cam plate the ecoentrio slot (56 therein works upon the pin 68 and draws the stop carrier to the left. when it drops to its normal position. Then the type keys arc operated to imprint the desired number upon the paper. The

operation of positioning the denomination stop and reloosing the carriage is repeated for every column upon the page.

Many changes may be made within the scope of the invention, parts of which may he used without others.
