tion or element 16 at the right of which and coaxial therewith is the supplemental or or tube 16? on which the tally platen section 17 is rotatably mounted. To the right-hand end portion of said sleeve 16 is operatively connected the line. spacing ratchet wheel ARTHUR w. SMITH, ornnw YORK, N. ,Y.', nssronon 'roj'nniviineron 'TYPEWRITE part or dividedplaten comprising a main sec-' 1 8 of the main platen section. At its right hand 'endj-the tally'i platen section 17 has fixedtofilt a platen head which (is formed peripherally with gear teeth, thus. constituting said head aspur gear wheel l9 rigid with the section 17. 'Arranged (at :the right I of the gear 19 is alknurled ann'ulus or paper V feed ng device 20 which is fixed to the right hand end portion, of'the tube or sleeve 1 6 and s thereby connected 'to turn .atall times with the. platen section, 16, said annulus being of substantially the same diameter as said platen section. To the right of the annulus 20 is'a spur gear wheel '21 which is adapted to "turn freely on thea'foresaid tube, thejgea'r 21 havingteeth corresponding wvith' thewgear wheel 19. To the right ofthe gear wheel 21 and fixedly connected therewith is a'ratchet wheel 22 which correspondswvitli the ratchet wheel 18 which i is contiguousto it atthe right, It will be understood,:however, that the ratchet wheel 22 is adapted to turn loosely on the tube 16%. Paper.fee'dingdevices of the usual Remington construction comprising pressure rollers23 and; 24/cooperate with the main platen i J section; and additional paper feeding dev ces, comprising short roller; sections, the

forward one-25 whereof is indicated in Fig;

controlled bythe usual releasing lever (not shown) which controls" the pressure rollers 23 and '24.. j In the present instance no feed ,roller's are proyided for cooperation withthe platen section17. It will. be understoodthat the main. platen section and its feedingde- 1, cooperate with, tlie annulus 201 and are vices are adapted to feed a Inain'sheetwhich is or may be arranged;insuperposed .relationship with the tally sheet or strip that is fed over the tally platen, and that in the case of a long main' shee which hasa'inar gin extending rightward beyond the tally .p latenpthe annulus 20 and its'pressure rolls cooperate wlth the right-hand marginal portion of said mam sheet to ass1st the main platen section and its feeding devices't'o feed said sheet evenly and truly. I

The tally strip mechanism is mounted on a supporting frame comprising upright arms 26 and 27 and a connecting cross bar 28. Said support may be mounted on the cross rod 12 of the'pla-ten frame and fixed to said rod near the'right-hand end thereof so that the rotary holders for the tally work sheet which are mounted on said frame are above the tally platen section 17. The d-elivery roll holder or tally strip spool 29 is mounted on a rod or shaft 30 and the other tally strip spool or receiving roll holder 31 is mounted on a rod or shaft 32 below the delivery holder, the shaft32 bearing ro; tat-ably in the arms 26 and 27. Arranged between the right-hand end of the roll holder 31 and the supporting arm 26 is a pinion which-is secured to the shaft 32 as by a pin 3a passing transversely through the hub of said pinion and through said shaft. Outsidethe arm 26 a similar pinion 35 is mounted on the outwardly projecting end of the shaft 32 and is suitablyvfixed thereto,

The extreme end portion of-the'shaft, indi 'cated by 32, maybe reduced in diameter and flattened at oppositesides to receive a short crank arm 36 which is formed with a hole having two stralght opposite sides that fit over the portion 32, said crank arm being secured inplace by'a headed screw 37 A- smaller screw 38 passes through the outeri end of the crankarm and is threaded into 7 the pinion 3-5, thus fixedly connecting said! pinion with the shaft 32. The pinions 33 and 35 are respectively connected through pinions or idlers 3'9 and 40 with the gear wheels 19 and '21, said idlers being preferably mounted to, rotate loosely on the frame rod 12. It will be observed that two parallel trains of gear devices are provided, said trains being arranged at opposite sides of the annulus 20 and that said trains connect the ratchet wheel 18 with the receiving roll holder 31 and the tally platen section 17,

The parts heretofore described correspond or may correspond, except for minor differences, with the construction disclosed in 'Clio B. Yaws-said prior application, Serial No. 762,1H. There is one difierence of importance, however, between the present construction as thus far described and said prior construction, namely, no tally feeding devices are provided for cooperatively engaging with the tally platen section in the present instance, the tally being advanced or; fed by the turning of the receiving roll holder 31 on which the tally strip or righthand work sheet is wound. The turning of the tally platen section 1'? simultaneously with the turning operation of the roll holder 31 through the gear "connections between the two parts facilitates the advance movement o f the tally strip which doesnot have to drag over a motionless platen section or paper support. Said platen section turns as thetal'l'y strip advances but this turning of the tally platen section does not, properly speaking, result in a feeding operation of the tally. The two platen sections or work sheet supports and the tally receiving holder are adapted to be actuated by novel line spacing devices comprising sets of nisms operative by a single hand piece or actuator, these devices being controllable by novel controllingmeans including a preventive device so that either the main platen section 16 may be advanced alone and independently of the other platen section and the roll holder 31, or on the other hand, the section 16 together with the tally platen section and the holder 31 may be turned or line spaced together. Spring mounted roller 'detents 4-1 and 12 cooperate respectively with the ratchet wheels 18 and 22 to maintain them and the parts respectively connected and controlled by them in adjusted positions follow-mg and between lnie spacing operations. The sets or trains of paper advancing mechanisms aforesaid comprise pawls or pawl members 43 and i l arranged side by side and adapted for cooperation respectively with the ratchet wheels 18 and 22, said pawl members being loosely suspended from a bearing in the formof a headed shouldered screw "or stud 45 which is'fixedly secured by a nut 46 to a radial supporting arm 47 which is loosely mounted on a sleeve 48 fixed tothe right-hand end plate 10 of the platen'fr'ame and concentric with the platen axle 14 which passes through it. The two pawls. are loosely confined. between the head of thescrew 45 and the arm 17 but are spaced leftward away from said arm by the hub portion 43" of the pawl member 13. The mounting of the pawl members 43 and 1 1 comprising the arm 47 is like that of the face "of the pawl member 13 and then is bent leftward forming a shoulder 49, the shoulder portion extending partly overthe front edge of the pawl member 4st. The extreme upper end portion of the spring is bent backward and e'ngagesvin a hole 51 in the pawl member 14. The tendency of said spring is constantly to press said pawl member 44 rearward and when it is free toexa "ert its pressure it will move said pawl member until the limit of such movement is reached as determined by the engagement of the shouldered portion 49% of the spring "withthe'frontface of the pawl member 43.

The independent movement of the p member 44 under the influence of the spring is, however, controlled and regulated b 1 vices hereinafter dQSCIlbQd. I

'Forward said housing the rock sh'aftis shaped to provide a downwardly extending hand-piece, handle,

Said devices comprise a linger 6S w1th the front face whereof the pin 67 is adapted to cooperate; This' finger' 58 thev details of which clearlyiappearin 7 F 1g. 4,'1s preferably inadeof sheet metal and is curved to conform"generallyto the curve ofthe platenfiand theline spacing aerallyleftward from" the lower end ofthe g.

ratchetwheels Ite utends upward at the front the annulus 20 and the gear wheel 21 and itslower end is bent' 'aroundand fixedly secured. to a squared rock shaft '69,

, a. r 1 bon strip yfiand the tally strip 71 11). some this rock shaft. being the same as is usually provided on the Remington machine for supporting the right-hand paper ,finger.

The usual paper finger is replaced in the present instance by the finger 68 which not .only exercises a controlling function on the pawl member 44 but also is adapted to act as a paper guide to properly direct the right-hand marginal bill sheet into cooperation with the annulus 20. The rock shaft 69 that supports said finger 68 is rotatably mounted, the left-hand end portion of said 'rockshaft bearing in a bracket 70- screwed to the front of the platen frame bar 11,

(Fig. 1) while the right-hand end portion of said rock shaft bears in the righthand endbar l and rojects slightly outward beyond said end liar. The projecting end portion has fixed to it by a screw 71 a rearwardly extending crank arm 7 2 to the free end of which is anchored the lower end of a coiled draw spring 73, the upper end of said draw spring, being anchored to one of the platen shift devices 9. Said draw spring tendshconstantly to swing the crank ,arm 7 2 upward, this upward movement being limited by a stop pin 74 projecting outward from the end bar withwhich stoppin the crank arm is normally in engagement as shown in Fig.3. The action of the spring 73, it will be understood, tends to turn the upper faces of the rock shaft 69 forward and to swing the finger 68.. forward so that said finger 1s normally mainta ned away i from the annulus as shown 1n said Fig.

affect the associate work sheet or tally strip.

It will. be understood that the spring 49 opposes the spring 7 3 and tends to swing the pawl member 44 inward toward its ratchet wheel but the spring 4-9 is considerably weaker than the spring 73 so that it is not effective to overcome the latter.

in order to overcome the spring 73 and render the spring 49 effective to swing the pawl member 44 into a normal position such that it will act on its ratchet wheel when the hand-piece G4 isactuated, devices are provided for automatically swinging the finger or preventive device 68 rearward so as to render it ineffective and cause it to release the pin 67 andthe pawl member 44. Said devices operate automatically] duringv travcling movements of the carriageor'platen mally inclines forward and downward as shown in Fig. 3 and is adapted to cooperate with a stationary cam member or actuating device 7 6 which is shown in detail in Fig. 2. Said cam member is formed with slots 77 which receive screws 7 8 bywhich the cam member is adjustably secured to the top plate of the machine. Said cam member is ,providedwith a rearwardly off-set portion 79, the right-hand end of whichis inclined downward as indicated at 80, forming a cam which is in the path of the finger 75. This camis so arranged that the finger 75 will engage with it when the traveling carriage has moved so far to the left that the lefthand portion of the platen section 17 has entered the printing field or been brought opposite the point at which the type bars strike when actuated. After the fingerengageswith the inclined face 80 farther leftward movement of the carriage will cause "the finger to ride up over said face onto the off-set portion 79 and this action of the finger will turn the rock shaft 69 .and swing the finger 68 toward the platen, bringing the parts to the position shown in Fig. 5. This movement of the finger 68 withdraws it from the pin 67 which leaves the pawl 44 free to be swung rearward by its spring 49 until arrested by the contact of the off-set portion 49 with the front face of the pawl member 43 as shown in Fig. 5. With the pawl members. thus positionedan actuation of thehand-piece 64 will effectively actuate both pawl members, causing them to cooperate with their respective ratchet wheels and simultaneously advance both platen sections and also the tally receiving roll holder, thus advancing or line spacing both the main and tallyvwork sheets. The offset portion 79 isof such length that it will operate through the finger/75 to render the pawl member '44 operative so long as the tally strip remains in the printing field and until the end'of the carriage travel toward the left is reached. When the carriage is retracted the finger75 will movebackward along and over. the off-set portion and down over the incline 80 and the snring 73 will become effective to swing the finger or preventive device 68 forward to the Fig. 3 position where it will maintain the pawl member 44 in inoperative position.
