To all whom 'it may concern:

Be it known that I, Care B. YAW', citizen of the United States, and resident of Arlingv ton, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates especially to what is commonly termed tally strip mechanism for typewritmg machines, and its object, generally stated, is to provide improved devices of the class specified.

To the above and other ends, my inventi n consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

The accompanying drawings show one form of my invention as a plied to the platen frame or carrier of a o. 11 Remington typewriting machine.

Figure 1 is a fragmentary top plan view of the platen and platen frame or carrier with my invention applied thereto. Fig. 2 is a fragmentary front elevation bf the righthand. end portionof the same. Fig. 3 is a vertical sectional view taken transversely of" the platen and looking toward the ri ht. Fig. 4 is a view corresponding to,-Fig. 3 ut showing some of the parts in difi'erent relations, other parts being omitted. fragmentary detail end view of the tally strip line spacing devices. Fig. 6 is a fragmenta sectional view taken on planes represente by the broken line as in Fig; 3 and lookin in the direction of the arrow at said line. ig. 7, is a. transverse sectional view of a lat-en showing a modified construction of in ing device for the tally strip. Fig. 8 is a fra entary faceview of the platen show-n in ig. 7, parts being brokenawa Theplaten frame or carrier'o theNo. 11

Remington machine is mounted ona carriage (not shown) and is com "os'ed of a'rear bar 1, side or end bars 2 an 3 and a cross 7 bar '4 connecting the end bars below the platen 5, the axle 6 whereof bears in the said end bars (Figs. '1 td ,4). At its ri lit-hand rend, the platen. is provided with t e usual line spacing ratchet wheel 7 with; which a roller detent 8 coiiperates. line spacing pawl-9 is mounted on an arid-10 pivoted to the platen axle 6. The, aw'lii'is caused to engage with the teeth of eratchet wheel and Fig. 5 is a turn the platen by hand controlled line spacing devices including a forwardly extending link 11. Angular arms 12 are secured to the cross bar 4 and provide bearings at their upper ends for a rock shaft 13, said rock shaft also bearing in the end bars 2 and 3. The rock shaft supports the rear end of a paper apron 14 that extends forward around the under side of the platen and is formed with openings through which the sections composing the front and rear feed rollers 15- and 16 are protrusive to contact with the platen or the paper thereon. The feed roller shafts are supported at opposite ends of arms 17' pivote at- 18 on three-armed members 19 supported on a rod 20 secured to the angular arms 12. Each member 19 has an upwardly extending arm 19 which is engageable b a finger 21 secured to the rock shaft 13. aid members 19 also have downwar extendin arms 19 con'ne'cted to draw springs 19". T e rock shaft 13 near its lefthand end is provided with an arm or finger The parts thus far referred to are common to the No. 11 Remington machine and need notbe further described. V The tally strip devices to which my "pre out invention more especially relates. are

supported on aframe or bracket 23 rovided wit two downwardly extending ranches or fingers 23 which receive screws 24 whereby the bracket is detachably secured to the end bar 3 (Figs. 1 to 4). From its points frame 23 extends upwmrdand forwardsover the top of the platen and inward or leftward toward the middle thereof, so that the tally stri rolls which are supported at the upper endortion of said frame or bracket are'dis above the laten and somewhat tor-the" ieft of its rig t-hand end. These tally stri rolls are shown in detail in Fig. 6. The elivery roll 25, which is the lower roll and is arranged somewhat to the rear of the receiving roll, isjournaled ona rod or arm 26 which isdetachably secured by a. nut 27 t0 the bracket 28 and projects horiof attachment to the end bar the supporting zontal'ly inward therefrom. A sto or cross arm 28 is suitably secured to the left-hand end of the rod 26 and the roll. is )ressed against, the stop by a coiled sprin 9 surrounding the rod 26 at the right 0 the roll, said 001 ed spring acting against a Washer 30 which contacts with the end of the roll. The construction is suchthat the washer 30 and cross arm 28 exert sullicient friction against the ends of the roll to revent it from rotating too freely and unwmding the tally strip to an unnecessary extent. The roll or core iece 25 is shown solid and may be of wood, ut of course may be otherwise constructed and of different material if preferred. The upper or receiving roll for the tally strip is shown as comprising a hollow tubular body 31 having end pieces or plu s 32 and 33 suitably secured in its enc s. These plugs areperforated to receive a rod or arm 34 which pro'ects inward parallel to the rod 26 and is et-achably secured to the bracket 23 by a nut 35. A nut 36 at the inner end of the rod 34 revents accidental detachment of the receiving :"011 and hand. The tally strip 38 is wound on thedelivery rollor core piece 25 and, as shown in Figs. 3 and 4, is led down from the back of the roll 25 around the platen and upward at the'front of the receiving roll to which the free end of the telly strip is or may be attached by a finger or clip 39 which is suitably secured to the tubular part 31 by a rivet 40 and extends len hwise of said tubular portion from whic it is only slightly separated. An arm or rod 41 is detachahly secured by a nut'41 to an extension 23 of the bracket 23. Said rod 41, which is shown as hexagonal, extends inward parallel with and below the rod 26'and has a reduced cylindrical portion 41" which provides a hearing fora combined support and guide in the form of a flanged spool 42. This spool is prevented from being accidentally detached from its hearing by a nut 43 and rovides a support for an end less transfer band 44 which is or may be an ink ribbon. The endless inklug band is hung on the spool 42 and-extends downwardly therefrom around the platen which it partially surrounds inside the tally strip 38. The tally strip and the inking band are preferably of substantially the same width, and the tally strip overlies the inking band which is interposed between said tally strip and the surface of the platen.

'a feeding of the inking ban Preferably the platen sheath is cut away to provide a shallow circumferential groove or depression 45 which receives the inking band and tally strip so that where these elements hug the platen they do not project beyond the surface thereof. This construction enables the wide work sheet or invoice (not shown) to extend widthwise through substantially the entire length of the platen and, over the tally stri and inking band without being caused by the latter elements to bulge at the lace where said invoice passes over them. t also enables the-invoice or bill sheet to be line spaced by the regular line spacing devices w thout line spacing or otherwise afl'ectin 'th'e tally strip. \Vhe'n, on the other han the tally strip is line spaced or fed lengthwise it is not impeded by the invoice sheet which overlies it. A. spring arm or detent 46 is secured by a screw 47 at the rear of the arm 41 and extending upwardly therefrom engages the teeth of the ratchet wheel 37, Wh10l'l ratchet wheel, it. will be recalled, is into ml with the tally strip receiving roll. T e' detent 46 and ratchet wheel 37 cooperate to maintain or hold the tally strip receiving roll in positions in which it may be adjusted. The delivery tally strip roll, it will be recalled, is frictiohally controlled. The consequence is that slack in the tally strip between the rolls is prevented and the tally strip is a]: ways taut. .VVhenthe tally strip is ad'- vanced either'forward or backward it slips or slides over the band 44 which is not advanced by these movements of the tallystrip. The engagement of the inking strip. or band 44 with the depressed face of the' platen is, however, sufliciently ti ht to cause if when the platen is turned for line spacing or other purposes. Because of this frictional feeding of the inking band by the platen during line spacing movements thereof, it will: be understood-that different portions of the inking band will receive the impact of'the' printing types for the different numbers written on the invoice and tally strip. Means are preferably provided for autonmtically advancing or line spacing'the tally strip, these means in the present instancev heing' actuated by the operation of the releasing arm 22. Said means com rise an arm 48 which is pivotally mounte, on the rod 34 at the right of the fiange34" against which it is maintained by a. washer 49.,

-Pivoted on a screw 50 carried by't-he free end of the arm 48 is a pawl member 51 hav-. ing a hub 52 which bears on the screw 50. The member 51 is provided with a pawl tooth 53 which is normally maintained in, engagemm t with one or another of the teeth of the ratchet wheel 37 by a coiled, spring 54, said spring surrounding the hub, 59 and having one of its endsspflin-na L. o f,

arm 48 and the other o'f its ends secured to the pawl member 51. At the side of its pivot opposite the pawl tooth 53, said pawl member 51 is provided with a laterally disosed finger iece 55. By depressin this nger piece the pawl tooth may he disenaged mm the ratchet wheel 37, permitting ackward and turning movements to be given to the. tally strip receiving roll by and. An actuating link 56 has 1ts upper end pivotally connected by a shouldered screw 57 to the arm 48 and extends downward and rearward behind the platen, the lower end of said link 56 being pivotally connected at 58 to a crankarm 59. Said crank arm extends upward and rearward from the rock shaft 13 to which rock shaft it is suitably secured in fixed relation. The rock shaft restoring spring 23 normally maintains the crank arm 59, link 56 and arm 48 in the positions shown in Figs. 3 and 4. When at the completion of the writing of an invoice, the release arm 22 is pushed rearward, turning the shaft 13 rearward and 2 releasing the 'feed rolls so that the invoice may be readily withdrawn, an automatic advance ofor line s acing of the tally strip will be effected. he rearward turning of the rock shaft 13 turns the crank arm 59 to which pulls the link 56downward, thereby swin ing the arm 48 and causing'the pawl mem er'51 to advance the ratchet wheel 37 and tally stri receiving roll a single space.

The norma positions of the feed rolls,

{ the release arm 22 and connebted parts, in-

4 of thefbody of the invoice and durin thereafter w .ties are operated a ouble lmprint of eachthe line spacing thereof, the tally stri wi 1 not" be written upon, her will its re ation with the, rintin point be changed. Ihe writing of the ho y of the invoice, of course,

0 is effected through the usual inking ribbon (not shown). .When the total or other megnoranda "is 'to' be printed on the tally strip; the depressed .portion 45 of the platen is brought opposite the printing point .and

ien the rinting instrumentali- 'ivill take lace. .The invoice will be printed m'as usual through'the main or ordinary ink-ribbon while the back of the tally strip 0 will reeeive iinpi'ints from, the underlying aukiliaryinking ribbon 4:4. The tally stri employed is of tissue or, other thin material so thatthe im rints made 011 the back there bf may easily e read through the telly strip 5 from the front, When theinking hand'44,

. and the tally strip has been exhausted it may readily be replaced by a fresh inking band.

In Figs. 7 and 8 I have shown another form of inking device for the tally strip,

which form may replace,if desired, the inking band 44.. In the modified con truction the platen 5 is depressed eirciunfcrcnthilly, as indicated at 60, and at the sides of the depression are formed slightly deeper grooves 61. An inking hand or strip (314 is wound one or more times around the depressed surface of the platen at (50 and the side edges of this inking band are fastened in the grooves 61 in any suitable way as by pins 63. It will he noted in Fig. that the. heads of these pins 63 are below the printing surface of the inking band (52. it will also be seen that this modified inking hand is in fact an endless band which will be turned with the platen when thclattcr is line s aced. When the exposed surface of the in ring band is exhausted, the used por- -tion may be disconnected from the platen and unwound until a fresh portion is ex posed, the used portion being cut oil and means for automatically line spacing the.

tally, strip; and also that, broadly speaking, an endless inkin ribbon is not new. Aeeordingly it wil be found that I do not claim these mattersbroadly in the accompanyin claims but only in combinations which 0 early distinguish from the prior art.

Various changes may be'madc without dc parting from the spirit of my invention.

\Vhat I claim as new and desire to secure by Letters Patent, is

1. In a t pewriting machine, the combination of a pl aten, paper feeding devices 006 erative therewith to feed a work sheet, a tal y strip s u porting device, an inking band interpose between the tally strip and said platen, said inking band being independent of said paper feeding devices, means for advancing said tally strip independently of saidplaten, and means for turning the platen in line spacing direction and thus automatically advanein said inking band independently of the ta 1y strip.
