Specification of Letters Patent.

Patented Feb. 4, 1913.

Application filed May 18, 1911. Seria1No.627,916.

To all whom it may concern. Be it known that I, Hnnnnn'rjH. STEELE,

' citizen of the United States, and resident of Marcellus, in the county of Onondaga and tate of New York, have invented certain new and useful Improvements-in Ty Writing Machines, of which the following is a specification.

-'My invention relatesto devic' for feeding and controlling the paper of typewriting machines and its general object is to provide improved devices of the character specified. Another object of the invention is to provide novel means for coupling and uncou pling the sections or sectional platen. Another object is to provide novel means for cuttingt'he 'paper.

Other objects wiilhereiuafter appear. To the above ends thy-invention consists in the features of construction, combinations of devices and arran 'ements of parts hereinafter described an particularly pointed out in the claims. I

My invention is applicable to typewriting I machines generally but is shown herein as gitudinal sectional view of the platen, Fig.

i 4 is an end view ofthe platen and the devices for connecting the sections, thereof.

said devices being shown inoperative posi tion. Fig. 5 is a front elevation of said devices. Fig. 6 is an end View showing the operated position oft-he throw-off devices for certain of the paper controlling elements.

As appears from Figs. 1 and 2, the main frame of the machine comprises posts 1 sup porting a top plate 2 from which rise standards 3 to which are secured grooved track -ways 4 connected throughanti-friction'balls 5 with a' slide or rear bar 6 comprised in a platen frame or,- carrier which further inparts of a divided or clu des' end bars 7 and 8. The end bars provide bearings for a platen axle 9 on which are mounted end to end-the two sections or parts of a divided or sectional platen. The left-hand platen sectioncomprises a core 10 and a sheath 11 and has operatively con nected to its left-hand end the usual or other suitableline spacing ratchet wheel 12 with which the ordinary line spacing devices, comprising a .pawl 12 and aconnected lever device 12 provided with a finger piece or line spacing handle 12, are adapted to cooperate. As appears from f Fig. 3 a platen head 13 provided with a hub 14 is secured to the right-hand end of the core 10' by wood screws 15, said platen head being overlapped by the sheath 111-. A set screw 14 in the hub 14 cooperates with the spindle or axle 9 to secure the platen head 13 thereto. The right-hand platen section comprises a core 16 and a sheath 17. A platen head 18 is secured by wood screws 19 to the left-hand end of the core 16, said platen head abutting the platen head 13 and:

being overlapped by the sheat 17, the end whereof abuts the sheath 11 so that the two sheaths provide a practically continuous writing surface throughout the entire length of the divided. platen. -The platen head 18 is'recessed as indicated at 20 to receive the hub 14'; and said platen head bears on a tube. or sleeve 21 which surrounds the axle 9 and at its left-hand end abuts -gainst the hub 14. Said sleeve 21 extends right-Ward through the end bar-8 and is held in fired relationship therewith by aset screw Secured -to the right-handend of the core 16 by wood screws 19 is a platen head 2-3,

said platen head being provided with a hub 24! and bearing on the hub 25 of a toothed wheel 26,.the platen 23 and the wheel 26 bev ing secured together by a set screw 27. Thehub 25 bears on the sleeve 21, thus providing a bearing for the right-hand end of the platen section, the construction being such that the right-hand platen section is adapted toturn on said sleeve but is prevented from endwise movement by the hub 14 at one end and the end bar 8 at the other end. the outer tire of the wheel 26 cotSperat-ing for this purpose, with said end bar. A

the screws 37 pass.

gal

toothed wheel 28, similar in construction to and having the same number of teeth as the toothed wheel 26, is provided with a collar 29 which is secured by a set screw 30 t3) the platen axle 9 to the right of the sleeve 21. Beyond the wheel 28 the usual. platen finger wheel 31 is secured to the end of the axle 9. As appears from Fig. l the teeth 26 of the wheel 26 are beveled at their ends while the spaces or notches 26* between said teeth are square or rectangular. The same is true of the teeth 28ta'nd the notches 28 therebetweenv of the wheel. 28. The teeth 26" and 28 correspond in number with the teeth of the line spacing ratchet wheel 12.

It will be understood that there is normally no connection between the two platen sections so that when the left-hand platen section. is turned or rotated the right-hand plat/en section will not be affected. in order to prevent the right-hand. platen section from being accidentally turned because of friction with the moving parts or otherwise, I provide means which normally holds the right-hand platen section positively against rotary movements. Said means comprises a looking or pawl member 32 provided with a hub 33 bearing on a rod or rock shaft 34 mounted on the platen frame at the rear of the platen and which is or may be the usual releasing rock shaft for the feed rollers. At its upper end the member 32 is provided with a tooth beveled at its ends to pass readily between the teeth26" and engage with the openings 26 in the wheel 26. The lower arm or portion of the member '32 is broadened, the rear edge 36 of this lower portion being substantially upright. Secured to the lower arm of the member 82 b screws 37 is a slidable member 38 forms with a slot- 39 through which the stems of The upper end of the member 38 connected by a coiled spring 40 with a pin all on the member 32, said spring tending constantly to hold the member 38 up in the Fig. 1 position, the upward movementbeing limited by the engagement of the lower end. of the slot 39 with the lower .screw 37. The lower end of the mom her 38 is bent or turned laterally as indicatcd at 42 to provide a broad tooth-like portion, the upper edge portion whereof is adapted to cooperate with the teeth of both thewheels 26.and 28, the length of this edge portion being greater than the distance between the wheels as will be understood from Figs. 2 and 5.

' Normally the connecting device 42 is inoperative and the locking tooth operative as shown in Fig. 1, the parts maintained in this position by a spring 44 which, as shown in Fig. 5, is coiled around the rock shaft 34: and engages at one end in a notch 45 in the hub 33, the opposite end of said spring being engaged in a collar fixed to the rock shaft 34. A collar t7 cured to the; rock shaft 34 of the member 232, spring 4% to prevent undue endwise' movement of said member while permitting it to rotate freely on the shaft 34.

Means are provided which operate auto; matically during endwise movement or travel of the movable element or carriage to render said connecting device operative, the result being that the two platen sections are automatically connected so that they will turn together whenever the right hand platen section is in the printing field, that is, whenever any portion of saidtion is opposite suitably seat the outer face cooperates with the the printing point. In the present case the means referred to comprise a fixed bar or camming device 48 which is arranged above the to late at the rear of the platen and eXt-encFs ibngthwise thereof. The bar 48 is provided "with ears 4-9 which are secured by screws 50 to the top plate. The right-hand end portion of the bar 18 is curved rearwardly as indicated at 51 to provide a cam which isadapted to engage with the ed e 36 durin leftward movements of the platen, the cam bar 48 being so arranged that its cainming face 51 will coiiperatc with the edge 36 just prior to the right-hand platen section reaches the printing point. The cam o1 forces the edge 36 forward, swinging the member 32 on the rod 34 to the position shown in Fig. l and the member 32 will remain in its forward position, the edge 36 riding along the front face of the bar 48 as long as the right-hand platen section isl within the printing field. The swinging movement of the member 32 withdraws the tooth 35 from the wheel or device .26 and forces the broad tootlrlike portion 43 into engagement with both the teeth of the wheel 26 and the teeth of the wheel 28, thereby connecting the two wheels. The part43 is partly engaged before the tooth 35 is entirely disengaged, thus prc venting accidental displacement of the right-hand platen section. Since the wheel 26 is rigidly connected with the right-hand platen section and the wheel 28 is rigidly connected through the shaft 9 with the lefthand platen section, the devices doinprising the part 42 and the wheels or oonnectible devices 26 and 28 thus connect the two platen sections so that if the left-hand platen section be line spaced, the right-hand section will be correspondingly line spaced at the same time. The line spacing'operation will be limited by the arrest of the sliding member 38 by the stem of the upper screw 37 cooperating withthe upperend of the slot 39; and in the present instance this cooperation and the consequent arrest of the platen will ta'ke place after platen seca single line oil.

the time when ios spacing-move nent. In other; words, the parts are so constructed that the all of the items are on a single sheet or tally through only a single line space .distance.

Thereafter the two platen sections will be locked or held from rotation and before additional line'spacing of either platen section may be obtained the platen must be moved endwise toward the right until the edge 36 has entirely disengaged from the bar as, permitting the springs 44 and 40 to restore the member 32 and the slidable device 38 thereon to the normal positions shown in Fig. 1. This provides a check to undue advance or spacing of the right-hand platen section and is useful in some classes of work.

My improvements in divided platens, as hereinbefore described, are particularly useful in connection with those kinds of commercial billing work wherein a series of bills or invoices are being written and a record is being kept of certain data from each bill. For example, the bill sheets may be written on the left-hand platen section while the totals of each bill may be written on a continuous sheet or tally strip which is fed around the right-hand platen section. It will be understood that the usual or suitable paper guiding and feeding devices may be employed in connection with the lefthand platen section, said devices comprising a paper table 52 and feed rollers 53 and 54; In writing tally strips it is common to write the debits in black and the credits in red and heretofore when a single tally strip has been employed the debit and credit totals were both written thereon so that the strip contained mixed records, some of the items being debits and some credits. It fre- I quently happens that the debits and credits are posted by difierent persons and wheni strip, one clerk, say, the credit clerk, must.

wait before he can do his work until another has finished. To overcome these other ob-Q jeetions, I provide a tally strip wide enough f for two columns to be written, one a debit; and one a credit column; and I further proi vide means for automatically dividing this; strip longitudinally after it has been written upon, so that when the different sections of; the tally strip are severed, the credit items will be onone strip or section and the debit f items on another. In carrying out this feature of .my invention, in'the present instance, I provide a continuous work sheet or tally strip 55 which is wide enough for two columns of figures and is wound upon a spindle or holder 56 having reduced end portions 57 seated in slots 58 in the upper end portionsof parallel plates 59. Said plates are connected just forward of the tally strip roll by a cross rod 60 and the plates and cross rod constitute a bracket or supporting frame which is detachably:

35 mounted on the platen frameerfca'niage.

The lower front portions of the plates 59 are providedwith hubs or bosses 61 which are bored out to fit over a supporting rod 62 arranged above and lengthwise of the platen and supported at its ends in the end bars. The rod 62 is preferably the usual paper finger supporting rod found in the Monarch machine. The lower rear portions of the plates 59 are provided with slots 63 which engage with the rock shaft 3d. The hubs 61 are suitably secured to the rod 62 in a way which'permits ready detachment of the roll supporting frame 59, 60. Above and forward of the rod 62 the plates 59 have projections 59 to which are secured by screws 64: a cutting bar or plate 65 and a guide plate 66, these two plates having downwardly bent end portions which embracethe plates 59 and receivethe screws 64.. The cut-ting bar overlies the guide plate 66 and there is a slot or opening 67 between the cutter bar and guide plate through which the tally strip is adapted to pass.

The upper edge of the cutting bar is beveled as indicated at 68 (Fig. l) to provide a cutting edge. downward and forward toward the platen and terminates in tongue-like portions66 The guide plate 66 extends:

which end close to the platen and cotiperate therewith to guide'the tally sheetupward away from the platen and into the slot 67's., As appears from Fig. 2 the rollsupporting frame 59,60 is secured at the rear of the right-hand platen section sothat the unwound portion of the tally strip 55 isdrawn frgm the front of the roll down behind the righthand platen section and upover the front thereof, passing over the. guide 66 and through the slot .67. The ordinary paper feed rollers or other suitable devices may be employed to coiiperate'with the righthand platen section at its lowerand rear sides to feed the tally strip toward the front. At the right-hand platen section and above the printing lineI provide paper feeding devices or pressure rolls 69. These rolls are .arranged in pairs, the rolls of each pair being supported on flanged portions of a sleeve 70, the two sleeves 70 being spaced apart and adapted to rotate on a rod. 71 extending l-en "thwise of the platen. Said rod has reduce threaded ends and is secured by nuts 72 to arms 73 and 74 which curve over the topbf the platen and are provided at their rear-ends with hubs numbered respectivelyl75 and 76, said hubs bearing on the rod 62. A spring 77 is coiled around the rod 62 and is hooked atone end over the arm 73, theother end of said spring being secured to a collar 78'fixed to the rod 62. The spring constantly urges the pivoted frame or bail comprising therod 71 andarms 73, 7 4 toward the platen and maintains thepressure rolls 69 in spring-pressed engagement with the right-hand platen section and 2.
