Application filed January l7,

To all whom it may concern:

Be it known the-t1, HARRY S. ll'lcConMAon, a citizen of the United States, residing inN ew York, in the county of New York and State of New York have invented certain new and useful Improvements in 'llypeJVriting ,Machines, of which the following is a specification.

This invention relates to type-writing machines in which, in addition to the usual linespacing mechanism for the revoluble platen, there is provided an auxiliary mechanism, usually at one end of the platen,for feeding a paper ribbon around the platen indepencl tionary. Such strips are employed for the purpose of recording the amounts of successive bills as the latter are written upon the main portion of the platen. During the writing of the bill the talley-strip remains stationary, and when. the bill is completed the operator copies the amount thereof onto the (Valley-strip, so that the latter at the end of the day may show the total amount or business transacted.

The principal objects of one portion of my invention are to provide improved means for holding the paper ribbon or tally-strip and to mountthe same in such a manner that they will he out-of the way (f the operator, so as not to interfere or obstruct the placing of wide sheets in the machine or the manipulation of such wide sheets.

The ribbon I carry upon two spools. The delivery-spool I place behind the papershcll', which is usually provided in rear of the platen. In this position said. delivery-spoo cannot possibly interfere with the operator in inserting or manipulating the wide sheets. The receiving-spool I place close to the shell to be well'out' ot the way of the operator s hands while he is handling the wide or I carry the paper ribbon be tween said spools over a platernwhichl. prelerably make of far. smaller cross-section than the main plz'tten, thereby giving clearance for said receiving-spool, the flanges of the latter overlapping the end of the main laten. Hence a very compact, simple, an inexpensive paper-ribbon mechanism is secured, and the operator is not bothered thereby when inserting, adjusting, or withdrawing the l prefer-to wind it by means ofa ratchet-wheel connected to thereceiving-spool and to opcrate the ratchet-wheel by-a pawl which is attached .to" the mechanism which is usually providedforreleasing the rolls which press the wide sheets against the main platen to feed the sheets therearound. Provision is made for adjusting the auxiliary platen relatively to the types, so that its printing-surface maybe brought into exact alinement or flush with the printingdine on the platen, and hence perfect type impressions obtained on the paper ribbon. Said deliveryspool is preferably mounted on a hinged frame, so

that at the end of the day it may be swung forwardly of the paper-shelf, so as not to be in the way of the cover which is usually placed upon the machine.

Another feature of the invention relates to means for securing accurate sidewise gaging of the main sheets. I provide a scale BX- tending along said paper-shelf andattach. to the paper-shelf a pair of side guides for the sheets, with means to clamp the guides. Each of the latter is provided with an index to cooperate with said scale to set the guides thereby.

Other fee ures and advantages will hereinafter appear.

part of the s etr agihg means.

- A cylindrical p aten 1 isrevolublymount' ed, by means of an axle 2,in the ends3 ofya platen-frame, .;prises a paper-shelf 4, inclining upwardly vvand rearwardly laten to aid in the introduction of sheets which usually carries or comfrom the rear side of. the

into'the machine. In said Underwood ma- 5 are mounted on harsh to aten is rotated by a Front and rear pressure-rolls 9 10 serve. to

press the sheets a amst the platen; the pressure being applie by means of-springs 11.

'A rock-shaft 12 has means [to re case said rolls, said means being well known and requiring no description. The rock-shaft 'is' 13 to a lever 14, pivoted at '15 upon an endof the platen-frameand rovided with a finger-piece 16, so that upon e ressing said" finger-piece the pressurel "re s 9 10 are withdrawn from the laten tn permit the ready insertion or with rawal of sheets ofaper. .Thelowerportionof the paper-she f4 curvesforwardly and upwardly around the platen'at- 1?: to guide the paper. The parts so ,far described are in common use on said Underwood type-writing machine. At the right-hand end ofthe mairi 'platen 1 I mount an auxiliary platen 18, whichis fixed to the platen-frame in position to be written upon by the types 5. Over this auxiliary platen is carried a paper ribbon or tally-strip 19 froma delivery-spool 20 to a receiving-spool 21. The receiving-spool 21 is supported upon a fixed rod 22, which in said machine .usually extends from one end of the platen-frame to the other and carries front paper-guidin fingers. T .(Not shown).

The auxiliary p aten 18 may be in the form ofa segment of acylinder, as illustrated,

and its surface may consist of rubber similar to the usual surface of. the platen 1, and in the form of the invention illustrated said seg- ,ment consists of a portion carved out from such a cylinder, as 1, the rubber facing being backed up b a seimenti23 of the wooden platen 1 is usually secured.

The auxiliary platen is mountedbetween a pair of plates 24 25, which are loosely mounted upon the platenaxle 2. Also mounted upon said-axle is a pair of arms 26' r 27 ,con between said plates. and extending backwardly and upwardly to the rod 22 to be held thereby agamst rotation about the axle $2, surface of the auxiliary pia'mn view illustrating the same as, appliedto aj aper-shelf. Fig. Qillustrates a chines like the ainst the front side of.

paper ribbon e: rubber facing of the 18 is curved a little eccenti'ically to the platen-axle 2 and adjustable about said axle to rotate different portions of said segment into the printinlg field to adjust the segment to thet pes. t will be seen that the printing-su ace of 18 is capable of considerable 11 and downadjustment while remaining the printing field, and hence there maybe resented to the types that portion of saidsurface which is exactly flush with the surface of the main platen 1. This provision of adjusting the auxiliary platen relatively to the ty nderwood, where the t pabars' are caused to strike against an anvi 28,

es is of importance in mawhereby they are arrested and the ty es are caused to spring backward 'to st ri e the platen. --The plate 25, Fig. 2, has a curved slot 29, and a screw 30, passing through said slot, is threaded into the arm 26 to secure the segl mental platen 18 where it is adjusted? he plates 24 ers rigidly connected by posts 31', 32, and 33, and a paper-guiding shield 34 extends across from one late to the other beneath the spgment to gui e the paper ribbon 19' forward v and upwardly to said segment,- said shield forming approximately which the spool 21 turns,- said shaft fitting loosely upon the 'rod 22. The'spool21 has a metal bushing) 38, which is attached to said hollow shaft y a set-srew 39. The spool flanges .40 are secured u the platen 1, as seen at Fi 4, t e auxiliary platen 18 being sufficient small in crosssectionto give the required flanges 40 or to the aper wound upon the spool 21. The latter 1s -confined between the arms 26 27.

Upon the outer end of the shaft 3754s fixed a ratchet-wheel 41, operated by a awl42,

pivoted at 43 upon the upper end 0 the link 13, which forms part of the mechanism that clearance to the on the spool 21 in any suitable manner an overla the end ofreleases pressure-rolls 9 10, Fig. 3, so that i whenever the pressure-rolls arereleased to ermit a main sheet to be withdrawn anda esh one inserted the ratchet-wheel 41 is ro tated by the pawl and the paper ribbon 19 iven a line-feeding movementgaccordingly. bus the line-feeding is. effected ,without at tention on the part of theoperato'r, and the liability of his failing 'to'feed the strip between entries thereon is avoided. Said spool 21 draws the paper forwardly from the s ool 20 and over a tubularpart 44, formeda ong flange 50 to confine the roll therod 22. The spool sleeve or core slipped upon an axle or holder 'Within said recess the upper edge of the paper-shelfv t, and thence down to the shield 3 and forwardly around the same and 'upto the auxiliary platen 1S and thence baclrwardly to 'wind upon the spool 2-1. To preyent overthrow of the latter, a brake 45-is suitably secured upon 46, which is secured by a screw 47 to the rear end of an arm 18, which extends hackwardlv and downwardly from. the top of the papersheli' The axle 46 may carry a flange -19,

and the spool 20 may carry a cor'iperating' 51 of paper rihhon. Upon the hub 52, secured to the flange 5 0, may he provided a yielding spring-finger 53, fitted in a slot 54 in the hub and projecting down into, a groove 5.5,forxned in the end of the axle 46, thereby releasahly holding the spool 20 upon the axle. i

. The arm 4-8 is attached to the outer end. of

a pintle 56, whereby the arm is hinged upon the plateri-iranle to turn from the full-line to the dotted-line position at Fi 2, thereby swinging the delivery-spool 20 from aposition of use back of the paper-shelf to a position of disuse forward of the same. Said pintle is rcvoluhly supported in a bushing 57, secured Within the tubular part of rim 44 of the paper,

shell. At its outer projecting end said hushmg 57 is diagrammatically recessed at 55 to receiyje the arm 48 and lockthe same against rotation. A 'compression'spring 59:, surrounding the inner end of the pintle, hears at one end against the bushing 57 and at the other end against a cap GOJproyided upon said pint-lo to hold the arm. 48 yieldingly in order to "turn the arm, it is pulled out frolntlie tull -line to the dotted line position at Fig, 5, and uponfhe ing swung to the dottedline position at Fig. 2- the spring 59 draws the arm again into said recess. 1

Along'the papenshel'l 4t extend two long slots 61 62, through which project roan Wardly lugs 63," riveted at {'34 upon the hacks of a pair of paper-guiding plates 65, which lie upon'thc front side of the paper-shelf. The outer edges ofsaid plates are bent np at cc 6? to form opposite gages for the side edges oi the Wide sheets of paper introduced into the These gages, may he adjusted.
