I have shownmy inventibn as applied to Vaytypewriting machine generally resembling the well known Remington typewriter, but itis to be understood that the nature of the invention is such ,that it may be readily adapted to other` forms of writing machines.

I have furthermore shown a form of my in' 90 vention which is especially adapted for use with a narrow perforated strip or work sheet` of the style shown in Fig. 15, said strip being adapted to the preparation of car record tags for a car record apparat-us such as that shown and described in the patent to W. E. Beecham, No. 618,388, dated January 31st, 1899. It will be obvious however that the perforated strippof the character shownis only one of many forms of 100 work sheet/with which my invention may be employed.

ln the drawings the main frame of the machine comprises corner posts l which rise from a base (not shown) and which sustain a top plate 2. Arranged above the top plate is a platen frame or carrier composed of side bars 3 and 4, a rear bar 5 and afront bar 6. The front bar 6 has a bean' ing, block 7 suitably secured t-o it and said 1'10 bearing block has journaled on it a wheel or roller 8 which coperaties with a guide rail 9 carried on supports 10 which project above the top plate and are pivoted on the frame of the machine in the usual manner. I

The guide rail 9 is usually shiftable but in the present instance I prefer to maintain' its ends and said bar is slo-tted to receive downwardly extending arms 14 which are ivoted on said pins 13 and are connected 1n the usual manner by a cross rod 15 supported at its end by screw pivots 16 (Fig. 4), said screw pivots being adjustably secured in the forwardly project-ing side arms 17 of a carriage truck 18. The usual limit ing screws 19 in the sides of the carriage truck are in the present casev screwed in until the bars at each s ide engage the pin 13 projecting 'from the neighboring end of the rear har 5 of the platen frame so that said bar instead of being rotatable about the pivots 16 is held from shifting motion and maintained in a lixed relation with'the carriage truck. Said truck carries the usual wheels or rollers 20 which coperatewith a guide rail 21 supported on standards 21 rising from the topv plate. The platen carrier or frame and the carriage truck comprise, as is well understood, a platen carriage, butin the present instance said platen frame instead of being shiftable on the truck is held in a fixed -relation'therewith i but is capable of being swung upward about the pivots 13 in the usual manner to expose the writing.

J ournaled in the side bars 3 and 4 of the platen carrier is a platen axle 22 'rovided at its ends with the usual finger w eels 23. Said axle supportsa platen of novel construct-ion and illustrated in detail in Figs. 5, 6 and 7. The platen as herein shown is a divided one comprising two parts or-sections each rotatable about the same pivotal axis independently of each other. The left hand or longer sect-ion of the platen comprises an inner thin metal tube 24 which surrounds the platen axle 22 and which, at its lefthand end, has suitably secured to it, as by soldering, an annular plate or ring 25. Surrounding the inner tube 24 is a somewhat shorter metal tube 26 the lefthand end of which is soldered also to. the ring 25 and the right-hand end of which is soldered .to a similar but somewhat thicker annular plate or ring 27 which surrounds and is soldered to the inner tube 24. A platen head platen axle -place as by 28 is secured to the annular plate 25 by screws 29, said platen head beingi per'lorate;

eret roug to permit of the' passa e t of the platen axle 22 and aving a central boss or hub 30 which receivesra set screw 31, said set screw abutting against the and maintaining the left-.hand platen section in xed relation with' said axle. The'outer tube 26 receives a sheath or covering 32 of rubber. Seated within the right-hand end Jbf the 'inner tbey24 is a metal disk 33 which is suitably Asecured insoldering. A line spacinglwheel 34 is secured to the disk `33 by screws 35 which pass through theline spacingl wheel and take intothreaded openings in t e disk.

The line spacing wheel is depressed as in`l dicated at 36 for the sake of lightness and is provided with a hub 37 which receives a set screw 38, the ,end whereof abuts against 'the platen axle 22. The line spacing wheel 34 is provided with peripheral ratchet teeth 39, as clearl shown in Fig. 13, said teeth being space apart a line space unit in the usual manner. The inner end of the line spacing wheel is reduced as indicated at 37a to permit entrance into the inner tube 24 thereby forming a shoulder 40. Mounted upon the inner tube 24 to the left of the shoulder 40 is a shorter platen section which comprises a metal coreor tube 41, said core at its left end surrounding and being rotatable upon the right-hand end of the tube 26, the sheath 32 on said tu'be 26 being cut ott to 'afford a bearing for the core 41, as clearly shown in Fig. 6. Integral with the right-hand end of the core 41 is an annular plate-like port-ion or iiange 42 which surrounds and hears upon the inner tube 24.

Secured to the portion 42 by headed screws 43 is a line spacing Wheel 44, said wheel being bored out to 't over and bear upon the inner tube 24. As most clearly appears .in Fig. 13 the line spacing wheel 44 1s provided with peripheral ratchet teeth. Some of these ratchet teeth indicated by the numeral 45 are sharp-pointed and others indicated by the 'numeral46 have broad tops, crowns or faces. The teeth 45 alternate with the teeth 46. The core or tube 41 of the short platen section is provided with a sheath or cover 47. Rivets 48 pass radially through the cover 47 and tube 41 and their outer heads 49 projectfsome distance he-A yond the sheath 47 and are rounded so as to provide lugs or projections for engaging the work sheet in a manner presently'to he described. Six of said projections are shown in the drawings disposed about `centrally of the length of the short platen section and spaced equally apart, but the number of said projections, 1t is to be understood, may be greater or less than six.

It will be seen from an inspection of Fig. 6 that the short platen section is held in theme47- xed relation lengthwise of the long section,

being confined between the shoulder or face of the ratchet wheel 34 and the righthand' end of the sheath or cover 32. It will further be apparent that the short platen section may be given rotary .'or line space movement independently of and upon the long platen sectibn, and it will also be apparent that the long platen section may'be given a rotary or line space movement independently of the short platen section.

Means for communicating'line space movements to the two platen. seoti'ons will nowbe described.

As clearly shown in Figs.` 1 and 3 an arm 50.. projects downwardly and forwardly from the side arm 4 ofthe platen frame and pivoted to said arm at 51 is a line space actuating lever 52 of suitable construction, said line space lever having a forwardly and downwardly curving arm or handle 53 and an .upwardly projecting arm 54. A coiled restoring spring 55 surrounds the pivot 51 of the line spacing lever and tends to maintain the latter normally in engagement with a pin 56, which pin is removably secured on an arm 57 fixed to and extending forwardly and upwardly from the side bar 4 of the platen frame. As shown in Figs. 2, 4 and 'f 14, the limiting pin 56 is provided with an annular flange 58 which is received in a slot 59-formed in the arm 57, said flange 58 being maintained in its slot by alat spring 60 which is secured to the arm 57 by a headed screw 60 and bea-rs normally against the flange 58, the construction being such that the pin is held from casual endwise displacement. yPivoted loosely at 61 at the upper end of the arm 54 of the line space aotuating lever is a horizontally disposed and rearwardly projecting pawl arm 62, said pawl arm being provided with a pawl tooth 63. which normally rests on one or another of the ratchet teeth on the line spacing ratchet wheel 44, being maintained thereagainst by gravity. Below the pivot 61 the lever arm 54 is provided with a threaded opening which receives a shouldered scr-ew 64, said screw serving as a fulcrum for an angular pawl arm 65. tends upwardly from 'the fulcrum 64 and thence is bent rearwardly so as to lie substantially parallel with the pawl arm 62, said pawl arm 65 being provided with a pawl tooth 66. The pawl arm 65, as will be clearly seen from Figs. 2 and 4, lies to the right of the pawl'arm 62 being disposed at the opposite side of the lever arm 54, so that said pawl arm 65 is in position to coperate with the teeth of the line space wheel 34. rlhe pawl arm 65 is loosely fulcrumed on the screw 64 and tends to drop by gravity into engagement with the line space wheel 34. an angular pin 67, however, is secured to the top of the pawl arm 65 near its rear'or The pawl arm 65 ex-A free end, said pin extending upward from the pawl arm 65 and then being bent horizontally leftward so as to lie over and in the path of the pawl arm 62. In some positions of the line spacing devices the pawl arm 65 lengages operatively with the line spacing wheel 34, but in other positions of the parts the pawl arm 65 and the, line spacing wheel 34 arevheld from coperative engagement by means of the pin 67 coperating with the pawl arm 62. This operation of the partswill be more clearly understood from a subsequent explanation. An arm 68 extends upwardly from the side bar 4 of the platen frame and has secured to it a horizontally disposed and inwardly projecting pin 69 which serves as a limiting stop for the pawl arm 62. The rear bar 5 of the platen frame is provided near its right-hand end with a flattened or plate-like portion 70, best shown in Figs. 2, 3 and 4. A spring arm 71 is secured to the under side of the part by a headed screw 72, said spring arm extending downwardly and forwardly and being bifurcated at its forward end. The fingers 73 of the'bifurcated end are curled back on themselves to hold the axle of a detent wheel 74 which is received be` in engagement with the teeth 39 of the ratchet wheel 34. A spring arm 75, similar to the arm 71, is secured at the left of the arm 71 to the under side of the portion 70 by a headed screw 76, said arm projecting downwardly and forwardly and being bifurcated to provide fingers 77. The ends of the fingers 77 are curled back on themselves to provide bearings for the axle of a detent roller 78 which isreceived between the fingers 77, and coperates with the teeth of the ratchet wheel 44 to hold the latter, and with it the shorter platen section to which it is fixed, in desired position.

-Referring now to the paper feeding 'devices, hanger arms 79 are pivoted at 80 in lugs 81 rising from the rear bar 5 of the platen frame, as clearly shown in Figs. 2 and`5. The hanger arms 7 9 support at their lower ends arod 82 upon whichA is mounted a plurality of feed rollers 83, three of said feed rollers being shown. The feed rollers 83fmay be of suitable construction and are adapted to coperate with the longer or left-hand platen section in a known manner, being maintained in operative engagement with said platen section by fiat pressure springs 84 which are fixed to the under side of the arms 79 by` screws 85, the upper free ends of said springs 64 coiiperating with lugs 86 on the iear bar 5 of the platen frame. Above the arms 79 and forward of their pivots a feed roll release shaft 87 'extends from side to side of the platen frame in rear of the platen, said shaft being journaled in f the plate 90 to said platen frame.

cuss, them in greater detail.

the side bars 3 and 4. A paper apron 88 is provided at its ends with ears 89 which are curled around and loosely clasp the shaft 87 thereby pivotally connecting the paper apron with said shaft, said paper apron extending downwardly and forwardly and be vsaid paper feeding devices coperate with the longer platen section only. A combined guide and indicating plate 90 extends from side to side of the longer or left-hand platen section at the front thereof. Said plate 90 is provided with ears or tabs 91 which are perforated to receive headed screws 92 which take in threaded openings in the front bar 6 of the platen frame, thereby 'securing The upper portion of the plate 90 terminates in a straight edge 93 which serves as a line indicator in a manner presently to be described. Below the ears 91 the plate 90 is divided into two triangular ngers 94 which curve downwardly and rearwardly around the platen, terminating slightly in the'rear of the front edge of the paper apron 88 which is provided with the usual platen scale 95 (Figs. 2 and 5).

The paper guiding and controlling means for the shorter or right-hand platen section comprises rear and front I guide members designated generally by the ' respective reference numerals 96 and 97 and shown in detail in Figs. 8 and 9. The rear guide member96 may be made of twoI pieces of sheet metal soldered together, as shown. Said guide member 96 comprises a securing plate 98 which has an angularly disposed lip-like portion 99 provided with perforations 100. The lower end of the body portion of the securing plate 98 is bifurcated to provide guide fingers 101 and soldered to said guide ingers are corresponding guide ingers 102 of a guide plate 103. The guide plate 103 is provided with guideportions 104 which are formed from lateral extensions on the body of the guide plate 103, said lateral extensions being bentas indicated at 105 toward each other and over the guidev plate so as to provide guide slots 106. The rear ends 107 of the guide portion 104 are'curved up away from the body of the plate 103 and corresponding curved portions 1 08 extend from the top4 of the body portion 103 behind the ends 107. The p airs of curved ends 107 and 108 at each side provide a `wide mouthed entrance to the guide slots 106 as will be plainly seen from'Fig. 8. The rear guide' member 96 is secured to the under side of the plate-like portion on the platen frame byiheaded screws 109 (Fig. .4), which screws pass through the perforations 100 and are received in threaded openings in the portion 70. When iixed in position, as shown in Figs. 3 and 4, the rear guide member 96 extends downwardly behind the right-hand platen section in place to guide the work sheet over said section, the guide fingers. 102 pressing lightly against the surface of the shorter platen section at the sides of thc rivet heads or projections 49 and permitting said projections to pass between them Y as the platen section is rotated duringthe operation of the machine. r1`he guide fingers are sufficiently resilient to yield to let the work-sheet pass between them and the plateny section. The guide member 97 is made preferably of a single piece of sheet metal which is cut out and bent back upon itself to form guide fingers 110, a guide portion 111 and asecuring portion 112 terminating in an angularly disposedflip 113. The lip is formed with perforations through which pass headed screws 114 (Fig. 3), said screws being received in threaded openings in the i undern side ofthe kfront `bar 6 of the platen frame and securing the front ide member 97 in place. Said guide member, it will be noted from an inspection of 'Figs 3 and 4, is adapted to receive the work sheet or paper as it leaves the rear guide member- 96, the guide fingers 110 extending down from the front of the platen toward the ends of the rear guide lingers 102, pressin lightly against the platen and at their en s being curved away from the platen as indicated at 1103' (Fig. 3). The guide fingers 110 lie at the sides of the path taken by the hemispherical rivet heads or projections 49 so that the latter may pass between said guide fingers as t-he platen section is given rotary movement, vsaid guide fingers sheet to pass section. j

The carriage truck 18 is provided near its middle with a rearwardly projecting guide arm 115 which controls a reciprocatory spool 116, said spool being mounted upon a rear guide rod 117 fixed at the tops of standards 118 rising from the sides of the top plate 2 at its rear (Figs. 2 and 3). The left iang'e 119 of the spool 116 serves as a stop, which stop is adapted to coperate with a line stop 120 adjustably mounted on a toothed stop yielding to permit the work between them and the platen bar 121 which stop bar is journaled on the standards 118. A margin stop'122 isadjustably mounted on the stop bar 121 at the right of the line stop 120, said margin stop being provided with a stop lug 123 which is adapted to coperate with a stop arm 124 secured to the carriage truck y18 by headed screws 125. It will be understood that the carriage is constantly urged leftward on its track- ways 9 and 15 by =a suitable carriage top ,plate Iof the machi-ne by headed screws spring (not shownf) and that the machine is provided with suitable escapementdevices which coperate in a known manner, when the printing instrumentalities (not shown) are operated, to permit the carriage to be moved a letter space distance ata time by said carriage spring. The printing instrumentalities are' of suitable construction and preferably resemble those of the Remington machine, dieririg however in this respect that each type bar is in the present in` stance provided with one type 'instead ofi two, the character of work necessita-ting letters 'of one size only. 1t will also be understood that the lflange 119 of spool 116 cooperates wit-h the-line stop 120 -to limit thel movement of the carriage i-n `letter space directionand that the margin stop 122 cooperates with'the carriage stop 124 to llimit' the movement of said carriage in returndirection. The stop devices and the Acarriage feeding devices are of any suitable construc-` tion. Thestop devices shown generally resemble thoseof the Remington 'machine and .p 4the carriage feeding devices are preferably like the carriage feeding devices of the vRemmgton machine. Itis not deemed necessary to describe in detail these parts.

An indicator or pointerv '126 'of Suitable construction is secured lto the front 4guide rail 9 and said pointer coeperates with a scale plate 127 secured to arms 128 fixed to the front bar -6 of Ithe platen frame. The scale plate shown isl a' short one and is intended for use only with the short rightliand platen section which is wide enough for a line composed 'of only ten letters or so. This :feature of the 'construction will be more fully understood from subsequent eX- planations.

As-'has been stated the particular form of niy invention yherein shown is designed for use in writing 'car record tags or'cards. For convenience in preparing said cards they are supplied inthe form of a continuous strip 15. The strip is .perforated'tran'sversely at intervals, 'as'indicated at 130, thereby dividing it into sections 3131 which may be readily separated or torn apart from one another after -the strip has been 2fed through the machine and the tagsections or cards 131 have been written upon. Each tag sec,- tion or card is formed near one end with a round hole 132 by means of which the hards maybe hung "upon the hooks of ythe car record apparatus shown in 'the patent `to Beecham hereinbefore referred to. To 'facilitate the handling and manipulation of the continuous strip 129by the typewriter operator, said strip is wound upon a core or center and is mounted upon a roll holder which will now be described. A lit-shaped bracket 133 (Figs. 1 and'2) is secured tothe 134. The stem o'f the vbracket supports a fixed 'upright :post or spindle 135 which..

screw 141, which screwfas clearly shown 'in Fig. 16, passes through one 'of the bracket arms 138, thence through Ithe "contiguous flange 139, throughthe `bore of the wooden core 140 and through the 1opposite ang'e 139, the threaded and reduced end 141 of 'said screw being .received in a threaded 'opening in the other bracket arm 138. The construction is 'such that the parts" are connected together so that the core 140 andthe rolled strip `thereon may freely turn on the Abody portion of the screw 141 between 'the flanges 139. Rotary-movement-ofthe flanges 139 is preventedby screws 1112 which pass through one of the bracket arms 138 Iand screw into the contiguous 'flange 139. The free end of the rolled up strip 131 is 'passed outwardly over a piln 143 which is arranged between the flanges 139 a't the front of rthe roll holder and near the periphery thereof.

Referring now to the operation off the paper feeding devices, the free end of the strip 131 after being passed 'forward over the fpin 1413, as shown rin Fig. 1, is thenin convenien-t position for lbei-ng |introduced into the wide or spreading mouth of the rear guide member 96, formed by the two sets of op sitely bent end portions or 'ears 107v and 108. The end of the stri-p 129 is passed down through the slots 106 in the rear guide inferir ben/said guide being of `suflicient width to permit the strip to pass freely therethrough and lthe construction beine' such that said strip is properly positioned widthwise of the short platen section by said 'guide member. rlhe strip is forced by 'the ends of the guide fingers 102 against the cover 41 of the short platen section rand said lplaten section may vbe slightlyturned to feed the 'strip and bring one or another of the projections 49 irrto'engagement with 'the first of the holes 132 in the strip. Thereafter as said shorter platen section is 'given rotary movement the projections 49 thereon engage one after another ywith successive openings 132 in the paper strip, .protruding outwardly through said openings 132 and-fitting snugly therein. The paper strip is thereby positively connected with the platen section and longitudinal displacement of the paper strip in reerating'with said'line space wheel will tend to maintain said paper strip in proper position for printin between the openings 132. After being d'forward from beneath the uide fingers on the rear guide member 96 t e leading edge of the paper Strip 129 will pass between the'platen and the curved ends 110a of the guide fingers 110 of the front guide member 97, said ends 110 forming with the platen a sort of mouth or entrance for receiving the edge f the strip 129, said strip being pressed thereafteragainst the platen section by the guide fingers 110. yThe front and rear sets of guidel fingers tend to maintain the Astrip 129 pressed against the under surface of the platen and in engagement with the projections 49v as shown clearly in Fig. 3. The relation between the platen section and the operative part of the strip 129 is best shown in Fig.' 7. It is obvious that when the platen section is turned, the projections 49 at the lower part thereof engaging the sides of the openings 132 in the paper strip will force the latter to. move around with the platen without possibility of relative displacemont. By positively connecting the work sheet withthe platen as described I provide a paper feeding means which is'espe'cially efficacious for thick paper, cards, stencil sheets and thelike. It will be seen that I provide, in combination with a platen,- a means operating automatically to positively connect the platen with the `work sheet at varying points, so that a continuous Work sheet may be employed and s'o thata work sheet .may be held from displacement or disarrangement'whle in the machine and be positively fed forward as Jthe platen'section' 1s rotated. Preferablywhen the end of the paper strip isr introduced into the machine the conductors report or other record (represented in Figs. 2 and 14 vby the reference character 144) from which entries are to be made upon thev sections 131 of the strip 129, is also entered in the machine in position to be fed around with the longer or left-hand section of the platen, the feed rollers 83 and the paper apron 88 coperating with thef platen to feed the record 'sheet 144 forwardly around with the lon er platen section in the usual manner. A er the leading edge of the record sheet 144 passes the edge of the scale 95, on the paper apron,said recvord sheet will be guided by the fingers 94 of the indicating and guide plate 90 so that said record sheet will be fed around with the platen and will pass out of the machine in contact with the top edge ofthe line indicator 93, as will best be understood from a consideration of Figs. 5 and 14.

Referring now to the method of operating the devices generally, and more especially tothe operation of the'line l'space actuating mechanism' so. as to. turn the platen sections to feed the strip 129 and the record sheet 144, it maybe `stated that/in the present instance each line of the conductors report or record sheetk 144 furnishes data for writing two lines on each tag section 131, and the invention'as shown is' adapted therefore to line' space the shorter platen sect-ion twice for each line space movement. of lthe longer "platen section. For the purposes offmore clearly explaining the operation of the parts, it will be ,assumed that the tag strip has been fed into the machine in the` manner hitherto described, that the` first line of therst tag section to be Writ-ten has been written and that said tag section .has been thereafter line spaced once. Under vthese conditions the parts will be in the positions'shown in Figs. 1, 2, 3,4 and 14. In these figures the record sheet 144 is shown as it' appears after it has been-fed around with the longer section of the platen and so as to bring it to the position best illustrated in Fig. l14', wherein it will be noted ythe first line of writing on the record sheet lis in register with the line indicator 93, said line of Writing being' represented by the "cross marks indicated by the references a and. a, and the tag strip is in position for writing the second line of the first tag to be written from the data supplied by the latter part a' of the first line of the record sheet 144, it 'being assumed that the first line of. the first tag section has already been written from .-the data obtained from the first part @vof the first line on the record sheet 144 and that said tag section is nofwl in position to have its second line written. As has been stated the tag strip 129 is wide enough' for only ten letters or characters on the line. l Consequently lthe scale plate 127 is provided with a scale'having. ten points only. The carriage, it will be noted, is in position such that'the first point'on the scale plate 127 registers with the indicator or lpointer 126, andthe margin stop 122 and the carriage 'stop 124 are in 'engagement so that the carriage cannot be moved any farther to the right'. The second line-of Writing on the tag section now in printing position is next written in the ordinary manner by operating the printing instrumentalities entries being taken from the latter part of the first line of the record sheet 144.` As the elli line is written the carriage will be moved one letter space at a time leftward across the top plate in a known manner and if ten characters be written on the tag section, said carriage will be arrested by the engagement of the'left flange 119 of the spool 116 with the line stop -1.20. During the movement ot' the carriage across' the top fplate the roll holder will be turned slightly on its pivot 135 so that that portion of the tag strip 129 between the roll holder and the platen will not be bent or crumpled, nor will the free movement of the carriage be interfered with. llt will, of course, be understood that as the carriage is restored from left to right said roll holder will turn 0n vits pivot 135 sothat at the beginning of each line of writing the roll holder will be in the positio-n shown in Fig. 2. The second line of writ-ing on the tag section having been completed, the linev space lever is operated by pulling the' handle 58 forwardly, causing the pawl teeth 63 and 66 to colperate with the teeth of their respect-ive line space wheels 44 and 34 to turn said line .spa-ce wheels until the pawl 63 is arrested by .the limiting stop 6 9 and effecting a for- Ward feed ot both platen sections. The line space Wheels by `this operation are turned from the positions shown in Figs. l and to the positions shown in Fig. 10. The.amount of turning movement of the two line space Wheels differs because ot' the difference' in the distances their respectlve pawl arms are pivoted from the fulcrum of the actuating lever 52, the construction being such that a differential line space movement ot' the two platen sect-ions is effected by operating said lever'52. in Fig. 3 the initial position ci" the teeth on the line space wheels with which the pawls 63 and 66 engage is indicated by the dotted radial line b and the positions of the said teeth at the completion of the line space movement are respectively indicated in Fig'. 10 by the dotted radial lines o and al. For purposes of comparison the initial position of the engaging .teeth of said-line space wheels is shown also in Fig. 10 and marked b as in Fi 3. From an inspection of Fig. 10 it will be noted that the' line space wheel '34 has been movedthrough an angular distance measured by the anale inclosed between the'radial lines Zr-d, said distance being equal tothe space between two of the teeth 39. Consequently the longer platen section, with which the line snacewheel 34 is in fixed relation will alsol be turned through a distance equal to the space between two of the teeth 39. This movement will ,bring the second line of writing on the record sheet 144 opposite the lme indicator. 93.' By the same operation oi the line space actuating lever, the line space wheel 44 has been moved a distance measured by -move toward the front of the to-tur'n the smaller platen section, which is tiXedly connected with said line space wheel, far enough to bring to the printing pointthe rst lino on the tag section immediately following the tag section just completed. As soon as the actuating movement of the lever 52 has been completed said lever muy be released and will be restored by its spring 55 into contacting engagement with the limiting stop-pin 56. During this restoring movement the pawl Vteeth 63 will be swung toward t-he front of the machine from the position shown in full lines in Fig. 10 to the dotted line 4position of said pawl toothshown in Fig. 11. During this movement of the pawl tooth 63 it will slide over one of the pointed ratchet teeth 45 and partially over the y next preceding blunt er broad faced ratchet 'tooth 46, coming to a state of rest at a point near the middle of the top face ofsaid tooth 46 as shown by the dotted lines in Fig. 11. The pawl tooth 66 will machine along with the pawl tooth 63 and when `said pawl tooth 63 comes to rest in the dotted line position the two pawl teeth 63 and 66 will be in substantially the same plane longitudinal of the platen sect-ions. During its movement toward the front of the machine the pawl tooth 66 will move forwardly out of that opening between the teeth 39-which is immediately in front of the dotted line d 1n Fig. 11, and when it='comes to rest, the point of said pawl tooth will lie above the next preceding opening between the teeth 39 on the ratchet wheel 34. Said pawl tooth will not enter said preceding opening between the teeth 39, however, as will be understood from what follows. In its positionof rest as vshown by the dotted line position in Fig. 11 the point of the-pawl tooth 63 rests on the periphery or crown ot a broad tooth 46 of its associate ratchet wheel so that the lpawl 63 is somewhat elevated, being higher in the dotted line position of Fig. 11 than it was at the beglnning of the ico lll@

line'spacingr operation as shown in F ig. o. i

The pawl tooth 66 will he held up just above the periphery of its associaterv ratchet wheel 34 by `means of the connection or bent pin 67 which rises from the pawl arm and lies over the paWi arm 62 so that when the latter is elevated, as shown by thedctted line position of Fig. 11, the pawl arm 65 `and its associate -pawl tooth 66 will also he clevated. After the actuating lever 52 has been released and restored by its spring 55, carrying the pawl teethfto the positions Just described, the first line of the new tag sect-ion may be written, the datajfor said line being taken from, say the rst part of the second line on the record sheet, which second line, it will be recalled, is now in register with the line indicator 93. lVhen the'nrst line of the new or second tab has been filled in the carriage maybe restored from lett to right and theline space actuating lever 52 again operated.

The rst stage of the advance movements of the two pawl teeth 63 and 66 is shown in Fig. 11,- the initial position of the pawl teeth 63 being indicated in dotted lines. From a consideration of said figure it will be seen that the pawl'tooth63 Yfirst slides .over the y downwardly into broad top face of the ratchettooth 46 from the dotted line-position to the ull line position, in which latter position said pawl.

tooth is shown as about to slide down into the opening just in the rear of the active ratchet tooth 46. During this first part of the movement of the pawl tooth 63 the pawl tooth 66 will move to the position indicated in full lines in Fig. 11, and as it moves will be held out of engagement with its associate' ratchet wheel by the connecting pin 67. As the actuation of the 'lever 52 is continued the pawl tooth 63 will' move rearwardly-l and the opening or space between the ratchet tooth 46 and the ratchet tooth 45 and will, when fully engaged with saidopening, be operative on the front or radial face of the ratchet tooth 45. As the pawl tooth 63 starts to move downwardly into the opening or space between the teeth 46 and 45 the pawl tooth 66 will be permitted to move downwardly with it, but the parts are so proportioned that when the pawl tooth 66 starts to move downwardly its rearward movement will have been suiicient to carry the point of said pawl tooth past the point of the ratchet tooth 39 from in front' of which said pawl tooth 66 had started. The result is that the pawl tooth 66 will move downwardly intov that opening between thetooth 39 which is immediately in front of the dotted line a? in Fig. 11. The completion of the actuating movement of the lever 52 carries the pawls 63 and 66 from the positions shown in full lines in Fig. 11 to the positions shown in Flg. 12. As the pawl tooth 63 moves from the full line position in Fig. 11'to the position at which itis arrested by the stop 69 as shown in Fig. l12, said pawl tooth, engaging the front of the ratchet ltooth 45 as previously explained, will eiect a rotary movement vof the ratchet wheel 44, which rotary movement, it will be understood,.is measured by the difference between the angle inclosed between the radial lines d-c in Fig; 12 and the angle d-c of Fig. 11.' This movement corresponds to the distance from the top of the engaging tooth 45 to the top of the next tion shown in Fig.

preceding tooth and will serve to turn the smaller platen section through a corresponding distance so as to position the second tag section for writing the second line thereon. As the pawl tooth 63 moves from the posi- 11 in full lines to that shown in Fig. 12, the pawl tooth 66 will move from the position shownin Fig. 11 to that shown in Fig. 12. Comparing these two igures it will be seen that the pawl tooth 66 will simply slide down the inclined face ovthat ratchet tooth 39 which is in front of the dotted radial line d, and that when the pawl 63 is arrested by the stop 69 said pawl tooth 66 will have just fully engagedl with the opening or space preceding the line d, but will not have affected the line space wheel 34. Consequently ,during the turning of the shorter platen section to move the first line of the second tag section away from the printing point and to bring the second line of said tag section to the printing point, the longer platen section will remain motionless as will the record sheet 144. The operator may next'refer to, say, the last part 'of the second line on the record sheet, which line remains in register with the indicator* 93, for the data for writing the second line on the second tag. It will be apparent that when the actuating lever 52 is released by the operator and restored by the spring 55, the line spacing wheels and their actuating devices will be in positions, corresponding with those shown in Figs. 1 and 3. on the tag section has been written the line spacing operations above outlined may be repeated as often as desired, so as to-'enable the third and subsequent tag sections to be written. I

It will be apparent that at two successive movements or operations of the line space` actuator 52 theline space wheel 34 and the longer platen section will have been turned only once while the line space wheel 44 and .-the shorter platen section will have been turned twice. The distance, therefore, which the longer platen sect-ion has been turned corresponds to the angle between the lines b-d, and this is sufficient to move one line of writing on the record sheet out of register with the line indicator 93 and to bring the next .succeeding line into register with said indicator. The aggregate distance through which the shorter platen section will have been turned at two successive operations of the actuator 52 corresponds to the angular space between the radial lines b-c in Fig. 12. As has been explained, this aggregate turning movement of the shorter platen section is made up of two successive movements, one of which is measured by the distance b-c in Figs. 10 and 11 and is considerably greater in extent than is the other movement which goes to com- Consequently after the second line Loader? g plete the aggregate movement measuredby the 'lines 5 0. The reason for this diiterence in the movements will be understood from a. consideration of Fig. 15, wherein the lines of writingl on several tagsections.,

131 are represented by cross marks and indicated by t-he reference characters e, ftand g respectively. The line e may be considered as the line written while the line space,

wheels are in the positions illust-rated"in Figs. 1 and 3, this line 'being thel second line on one of the tag sections. The line f will then be the line .which is writtenwhen. the

line spacingwheels have been moved from the positions shown in F ig. 3 to that shown ip Fig. 10, said line f being the first line on the next succeeding tag section. The lline 57 which is the second line on said `succeeding tag lsection will be ywritten when the line spacing wheels have been moved to the position sli'ownin Fig. 12. YIt will be ap arentr from a consideration of Fig. 15`that it will be necessary, in order to get from the last line e-on one tag section to the irst line f on the next succeeding tag section, tomove the shorter platen section about threeA times as far as it is necessary to move or turn said platen section to get from the first to the second line on one of the tag sections.

It will also be seen that by providing the line spacing Wheellt with two sets of teeth and 4G of different dimensions and alternately arianged the mechanism is adapted so that the print-ing always, comes between the projections 49 and the latter are never brought into contact with the types.

I have described the longer platen section as 'serving in eiect as a copy-holder-which is .automatically actuated intermittently to` bring successive lines to position to be copied upon ythe 'work sheet or tag strip 129. It will be obvious, however, that the longer platen section may be employed as a platen in the ordinary way and that a work sheet may be fed around with said platen section in the same manner as the record sheet 14A.

-It will furthermore be obvious that though i I have shown` and described. the tag strip or work sheet 129 as' being given alternately varying extents of line space movement the parts may be constructed so vthat said tag strip need not be line spa-ced in this inanner nor need the work or record sheet on the loiigerplaten section be automatically line spaced at every other movement of the work sheet 129 as described.

It is. I believe, novel to provide a divided or sectional platen with a single line space actuator which operates a plurality of platen `sections together at one time and j which at another'time operates only certain l of said plurality of platen sections, while cert-ain other of said plurality lot' platen sections remain inoperative, the change being j automatically eliected and provision thus' work sheets cooperating `with the platen sections. 'l'his principle l therefore desire to claim` broadlv 'and withoutlimiting inythe' inanncr described to automatically po-I sition the record sheet, facilitates an accurate filling in of the tag strip or worksheet,

it'should be understood that `the operator lmay, if desired,` copy the data from the record sheet in' the ordinary manner and without introducing the record sheet into the machine.

I have shown my improvements, comprising the paper'fecding and line spacing deyiccs, as combined in a mechanism which facilitates the production of certainspecial work forms'. It is obvious, however, that my novel devices .instead `of being employed in combination may be made use of separately or in different relations from those being made for differential feeding ofthe shown and explained. It is furthermore to beiinderstood that from some aspect-s of my -invention t-he shorter platen section may be as a rotary device pro.

regarded merely vided with means such as described for positively engaging and feeding the Work sheet. Various changes may be made in the construction and arrangement of parts without departing from thespirit and scope of my invention.
