TYPE-WRITING MACHINE.

"To all whom'it may concern V 7 Be it known .thatI, A'Lrneo G. F. KUnowgsnr, a'subject of'the Emperor of Germany,

but having taken out his first but not his final United States naturalization papers,

residing in Brooklynborough, in the county of Kings, city and State of New York, have invented certain new'and useful Improve- V ments in Type-WritingMachines, of which I 1O the following I is a specification.

My invention .relates to typewritingimachines, and is herein disclosed as applied to tally-strip devices on an Underwood stand ard' typewriter." Such devicesare usually used for preserving" a tally-strip record of itemson sales sheets, bills, etc-., and usually include'a holder both for the tally-strip itj self and for the carbon paper which makes,

often put into-thefh'ands' of people entirely [this feeding may be made inefiective by the simple ad ustment of a finger-piece. I'have also found it possible to make each casting off of the usual feed rolls effective to feed along thetally strip, and to make this feeding ineflective at will by the mere adjustment of another finger-piece.

Ihave also found it ossible to make a very simple mechanism accomplish this by providing a single pawl which may be con .nected to either the line-space lever or the casting-01f lever, or to' both. Other features and advantages will hereinafter appear.

orline-spacedevice shall be effective to feed the tally-strip. 1 a V 1 In the usual Underwood typewriter carriage, a platen 1 is fast on an axle 2 which is journaled in the end plates 3- and 4 of the platen frame of the typewriter. carriage and is provided at its ends with the knobs 5 by which.

.it may be'rotated. The typewriter carriage also includesthe usual front-and rear feed .rolls 6 and 7 which are journaled in frames.

f 8 and 9 pivo-ted on a shaft 10, and are normally pressed against the platen by springs 11, so that when the work-sheet 12 is placed on the usual paper table 13 behind the platen, it may be passed down onto theapron 14 into the'bite 0f the rear feed rolls 7 and thus may be fed around the platen by rotating the platen, since the front and rear 7 located a tally-strip device which includes a pointed spindle 24, on which is mounted a roll of paper 25 adapted to be-used as a tallyfeed rolls hold it against the platen.

The carriage includes the usual line-space lever 15'whiohis pivoted at 16, so that when itis thrown to the right, the bell crank eX- tension 17 thereof strikes the turned-up end of a slide 18 to-drive said slide-rearwardly, causing the usual pawl 19; to engage the usual line-space wheel 20 which is fast on the platen axle 2 and thereby rotate the platen. I

be varied by the usual handle 21, and the The amount .of this rotation may end of the rotation is limited by the usual stop 22, against which a lug 23 on the pawl 19 strikes when it reaches the limit of its throw.

At the right-hand end of the carriage is strip. The free end ofthis paper is carried down across the paper table 13 beneath the platen and up in front of the platen until its leading edge reaches a winding roll 26, said roll comprising a spring 27 under which the leading edge of said strip 25 may be caught. In the part of the platen occupied by the tally strip 25, there are no pressure rolls 6 01: 7, and the sectionof the platen around which said strip passes is free to turn on" the platen shaft 2, thus allowing the section 28 of the platen to be turned around freely by the tally-strip 25.

In order to movethe tally-strip 25 along at the operation of the line-space mechanism, if such movement is desired, the roll frame supporting the mandrel 24. Near the outer end of the shaft 29, thereis'fast a.

ratchet wheel32 which is adaptedto be engaged by a pawl 33, said pawl being adapted to be driven at every operation of the line-- space lever 15' To effect the drive of. the Fig. 17 is a perspective view of the devices for determining whether or not the feed roll pawl 33, the slide l8'of the line-space mechawhich extends from oneendto the other :of the carriage, and said shaft includes a rock nism is adapted to rock a long rock shaft'34 i arm 35 which may drive the pawl'33. 1 To effect this driving, said rock arm 35 has piv oted thereto a plunger 36provided with a slot 37, so that the plunger. may slideovera guiding pin 38, with the result that when the platen, the plunger36 moves forward the line-space lever 15 is moved to line-space;

and strikes a pin 39, on an oscillating plate 2 40 on which the pawl:33 is pivoted. 1 The:

plate 40 is journaled on the shaft29 so that i the pawl 33, when driven as above described,

will engage with -and rotate the ratchet wheel .32 and thereby carry. around the V I winding roll 26.. r 1

The connections between the shaft 34 and the slide 18 includea 411which ispivoted thereto andalso to arock'arm 42 fast to the shaft 34. and dependingther'efrom.

This rearward motion of'the slide. 18- turns the rock arm 42 rearwardly, whilethe upstanding rock arm;35;at the opposite end of said shaft turns forwardly and drivesfithe slide 36 forwardly, effecting the turning of the winding reel in. a manner described. The I jshaft;34.is 'journaled in upstanding ears 43 and 44 forming part: of brackets mounted on the usual cover plates 45 and-46 on the end pieces of the typewriter carriage, and

This connection includes the slide54' which "is adapted to underlie a forward extension 55 of the plate 40. I The main part of the slide 54 lies clear of the plate 40; but, a turned-up back to its normal position, shown in Fig. 8. r

and 7 are cast off. For this purpose, it is I connected to the usual casting-off fingerpiece-49 which is pivoted at 50 an'd which casts ofi the feed rolls by. rotating the usual 125 i lu'g '56 on said slide underlies the 'very front end ofgthe' plate 40, while'the'lowenend 'of which connects the usual link 58 of the castfio ing-ofl connections to the a usual arm 59 {which is operated by 'the "finger-piece 49. *The connections "are =such that' the throwing down of the finger-piece 49lifts the slide 54 and thereby-raises the front-end of the plate 40,-thus"drawing down therear end-thereof together withthe pawl 33' and rotating the windingroll 26. l

" On'throwing back the finger-piece 49, a

spring'60 draws'the plate-40 to nornialposition, thus throwing the pawl 33'back toits normal position. 'pawl' 33 is held clear of the ratchet-32 by In this position, the

' afixedcam-61 formed by a downward pro- 7 'jectionof-.'the cover plate 46, (Figs. 4 and 17), said pawl having adownward exten- '"sion 62 comprising a pin 63 which, in its 'normalposition, lies against the front face 'of's'aidcam. "The rearward-throw of the plate by the spring islimited by a stop 64 which is formed as a downward extension of said plate and strikes} against the front side of'a rod'65 within the typewriter carriage. I

" "If it'is desired to cause the line-space lever 15 to be ineffective on the winding roll 26, .a finger-piece 66 maybe thrust rearwardly,

thuscarryingrearwardly a slide67 on which it, is formed, said slide having mounted V therein the headed pin 38 which'forms a guide for the slide 36. This carries the pin 38 into the position shown in Fig. 12,- in

which position the slide 36 is unable to strike the pin 39 because thepin 38 holds it clear of the pin39; therefore the operation of' the line-space lever at this time willbe without eli'ect on the plate 40, and conse I ""quently without eflect 0n t e n g ;reel 7 In the same way, if it is desired to make the operation of'the casting-off lever'49 ineffective on the winding reel- 26, a .fingerpiece 68 may be pulled; forwardly into the position'shown in Fig. 11, in which positionthe guiding pin 69 which guidesithe' slide54,

by riding in the slot 70 thereof, carries the slide in front-of theend of'the plate 40, thus making said slide ineffective onthe plate 40, and therefore ineffective on the 'Winding roll 26. The slides 67 and 68 are? shown .in their normal positions in Figs.

space mechanism and the roll casting-off mechanism to be effective on the winding roll 26.]

Inorder' tomake sure that the slide 36 will; not slipfree of the, pin 39,"the end of said slide isforked, asseen at Fig. 7, so

q that 'if'the slideengages the pin 39 at all,

it will positively be'kept from slippingto either side of the-pin. For the same reason the front extension of "the plate 40 has, a v Tdownwardlyturned cam face 72, which has the slideis'pivotedto the usual pivot 57 V a tendency to cam the slide 54 rearwardly into the bend between the cam face 72 and the main part of the plate 40, thus preventing the slide 54 from slipping free therefrom. The spring 60 is anchored in a downwardly projecting arm 73 fast to the bracket on thecover plate '46, thuskeeping the spring concealed within the end plate of the typewriter carriage.

roll 25 iscarried, is adapted to be thrust inthrough the wall 31 of the tally-strip device through the center. of the roll 25, and is long enough to extend beyond'the wall 30,'in which position it thrusts aside a catch 74 in theform of a slide- This catch (Figs. 9, 10 and 13) hastwo sides 75 and 76 ;over end 78 by which it is adapted to be pressed down against the tension of a spring 79, which normally holds the catch 74 in its j. upperposition. The catch 74:is guided'by its two sides 75 and '76 in a hood 80 having tenons 82, which engage and aline within slots cut in the wall 30, said 'tenons also 'nal for the mandrel 24. In orderto hold the mandrel 24 at the proper place, the sides 75 and 76 of :the catch 74 engage in a circularslot 84 cutin the surface of'the' mandrel 24 and in which the sides 75 and 76 seat themselves when the catch 74 is lifted upward by its spring 79. The knurled righthand extension 8501 the mandrel 24 is large enough toprevent the mandrelifrom'slipping too far when inserted into the opening 86 in the wall 31 in which it is journaled.

In order to make it impossible for the roll 25 to be wrongly placed on the mandrel 24, said roll 25 hasa core 87, which extends entirely out to one end 88 of theroll while terminating short of the opposite end there- --'of. When the roll is to be insertedin the tally-strip device, an end plate89, having a tightly when theroll is inserted so that the core '87 bears against the margin of the opening in'the spider.- When thus inserted, a hub in the form of a boss 93 on the end plate 89 bears against the wall 31. The mandrel passes through the end plate 89, the core 87 openingin the spider 91, and out until it engages'and is caught by: the catch 74. The spider 91 has its outlying spring ends bent s shaped toeatch in openings in 1 an end plate 94 which has a hub in the form of aIboss 195,. said .hub adapted to engage theboss-bushing 83 and to be fastened thereto by a set screw 96.

I The windingroll 26 may include a wooden body 97, which is held by a set screw 98 to 7 its shaft 29. Said shaft is j ournaled in-the end walls and 31-, and to hold it in position,vit is provided with a shoulder 99 bearing against the inside of the end wall 30,

' and it is also provided with a collar .100 outside the end wall and lying closely against f saidflwall, said vcollar being .held to the shaft 29 by. a set screw 101 Inorder to roll 26.

1" spring catch 27 lies inan axial slot 104 on said roll, andsaidspring is hinged at the opposite side of said roll at 105, Figs. 3 and 5, with the result that the arcshaped portions of the spring extending around to the hinge point furnish sufiicient springiness to holdthe main'partof the spring in its slot 104, to thereby clamp the leading edge ofthe tally-strip. In order to make it easy'to raise the spring catch, a 'finger-hole 107 is' .7 cut out :of the winding roll; paper used with these tallyrstrips is often in the form of a single-rolled strip having two colors. In order to'make sure that the typist shall insert thisrolled strip correctly on its pointed mandrel or spindle shaft 108, it

' is provided with a core 109 which extends entirely out to the left-hand side110 there-V "of, but terminates short of the right-hand sidelll, The right-hand side 111 is adapted to 'receivethe hub of 'a flange plate 112,

and, for this purpose, the wooden core is,

providedfwith two axial openings 113,-either one of which may engage a pin 114 which Said flange plate 112 is providedwith an outwardly-extending hub 115; which bears against the plate 31 and which also forms V the support' for a detent116 which'is adapt- V projects endwardly from the face of the fiange for the purpose 'ofentering one or the other of the 1h0les113, thus compelling the flangeto revolve with the roll.

ed to lock the flange plate 112 to the mandrel 108, so that the two revolve together; The

detent 116,'Figs.' 9 and 14, is seated in a bore r 117, and is pressed inwardly by a spring 118,

so that when in the proper position, said detent is adapted to enter into a kerf 119 in the mandrel 108, and when thus seated, the

V mandreland the flange turn asa unit. The spring 118 encir'cles'the hub 1151and is held 1n place'by a pin 120, which extends across a cut-away segment of the-hub:115.

The carbon The outer end of the mandrel 108 has suit '7 ably attached thereto a crank handle 121, by

which it may revolve and the adjustments are such that when a carbon roll is inposition on the mandrel 108, the turning of the handle 121 will cause the detent 116 to'seat V itself so that the carbon roll will turn with the handle. V 7

The end .110 of the carbon roll bears against a spider spring 122, which may be substantially like the spring 91, and bears against a flange plate 123, which is mounted like the plate' 94 on a hub 124, and held by a setscrew 125 to the internal extension of a hub 126; This hub includesa latch 127 like the latch 74 and the otherparts may be substantially. identical so that the mandrel 108 maybe released from the latch 127 whichv normally holds itbydepressing the upper end of thelatch. Y r While the paper roll 25 and the carbon roll turn freely on their shaft or, mandrel, the winding roll 26 is fast to the shaft by the setscrew 98. V

In order to guide and protect the slides 67 and68 from dust, and toprevent parts, paper, vetcQ, from catching therein, they, are beneath a cover plate 129, whichis formed 46 at'theiright-hand end ofthe carriage.

The slides are also guided by fixed pins 130,

which are embraced by slots 130 on the slides. V. i

. as a bent-over upper extension of the cover j In order to enablethe machine to have the broadest possible utility in aiding the oper-' ative to position work-sheets thereon,'it is provided with an adjustable leading end 7 gage 131, formed as an extension of a plate 132, said plate being adjustable, by screws 133, which pass through slots in said plate and enter into brackets 134.7 and 135, which are slidably mounted on the rod 65, which is found in many Underwood typewriter carriages; The plate 132 is not only provided with the end gage 131, but alsoincludes a slde gage 137 at the right-handside' thereof of the tally-strip, said gage 137 usually being adjacent the edge of the tally-strip.

The plate 132 is adjustable longitudinally of the carriageto enable the side gage 137 to be positioned at the right position and to hold it properly. positioned. The brackets 134 and 135 are provided with bent-over extensions 137*, which are also perforated to embrace the rod 65, and where bent over,

which may' be used for adjustingra worksheetwhich is to be partly or entirely clear are providedwith springs 138, which frictionally bear against the rod, thus taking up lost motion and preventing rattling. The side gage 137 maybe positioned longitudinally of the carriage to correspond with the letter-spacesthereof, and, for this purpose,

the rod 65 is provided with teeth 139, which r are adapted tojbe engaged by a tooth 140,

pivoted on the gage 137 and adapted. to be swung into and out'of said teeth by a finger piece 141, forming an extension of said tooth.

A second side gage142, lying on the paper table 13, may be'also used for positioning elther the same or a separate work sheet,

said side gage being formed as aturned-up edge of a plate 143, which lieson said table,

form an adequate bearing for thefipart 28.

where it abuts against the main part of the platen, and thus avoid the usual sagging. of split platens, the axle 2 ofthe platen is provided with a sleeve 148,. which is held fast to said axle by a set screw 149,.said sleeve ex tending within the part 28 ofthe platen and forming a broad solid bearing for a hollow sleeve 150, which is screwed fast to the wooden core 151:0f the part 28 of the platen Y latter, this structure serving to facilitate jasstiffness is materially added to by thegirderlike structure formed by the cores 159 and and is also supported therefrom by a collar. 147. The .sleeve 148 hasalso bearing thereona hollow sleeve 152, which forms a support for the main part of theplatem'being provided with a collar153, which engages the usual wooden body 154 of the platen, said hollow sleeve also having atthe opposite end a flange extension155, through which passes a screw156 entering the wooden core 154, thus holding saidncore fast tothe sleeve 152; the sleeve 150 having 'asimilar flange and screw, and'als o a collar 147 at theend opposite the flange, both fast to. the core. The sleeve 148 compels the sleeve: 152 i to turn with it, because the former has a lug 156, which closely fitsan axial slot in the sembling. The part 28 of the platen has its wooden core 151 slightly spaced awayfrom I the core of the mainpart of the platen, so that there is :a slight .open space 157, be-

tween, the two .parts of: the platen face, this being bridged over by abutting ex-H tensions 158 of the usual rubber surface of the platen. It. willbe seenthat the short sleeve 148, strengthens the platen at the critical sagging. point, without materially adding to theweight of the structure, The

152 in their coiiperation with their respec tive cores 151 and' 154, through their collars and flanges; yet this enables the sleeves 150 and 152 to be comparatively light.

The frame which vcomprises the side pieces 30 and 31 supportingthej roll 26, etc., is adaptedtobe swung either into nearly upht p i ion, which th no mal position.

shown in full lines in Fig. 15, or thrown down either forward or backward into nearly horizontal position, shown in dotted lines in said figure. This enables the rolls to. be swung down when the machine is not inuse, thus reducing the height of the ma-,

chine and enabling it to fitrin anordinary cover, ortoj occupy an ordinary typewriter desk, into the body of which it may slide when the cover of said. desk is pulled into horizontal position. In order to permit this,

the'side- pieces 30 and 31 are journaled on the shaft 29, which shaft in turn is journaled in brackets 159. v

The brackets 159 are formed as turned-up extensions of a plate 160 which extends between them, thus giving rigidity to the structure. Fast to the right-hand bracket 159 is an extension collar 161, on which the side piece 31 is journaled instead of directly on the shaft 29. This collar 161 iscircular except at a point near the bottom. but

slightly in. front of the bottom, at which, point a hollow 162 (Fig. 4) is cut into it,

which hollow is adapted to fit a detent roller 168, said roller being journaled very 'loo sely in openings 164 (Fig. 9), both in the down.-

ward extension 1650f the side wall 31 and also in the-upturned extension 166 of saidwall, which is spaced therefrom and lies against the end of the collar 161. .Theroller 163 is pressed strongly a ainst the collar 161 by a broad flat spring 16 which throws the roller 163 into the hollow 162, when the roll frame is in'the proper operating position.- The frame, however, may be swung from,

said position bypressureof the hand,'thu s forcing the roller 163 to ride out of its hol- I low and ride in the circular face of the col: lar 161. i

In order to prevent the brackets 159 from turning on the rod 65, the shaft 29 is journaled in a fixed bracket 168 fast on the end of the typewriter carriage frame. It will be seen that the broad'face of the end of the collar 161 bears against the upturned extension 166, which, in'turn, bears against the broad face of the ratchet wheel 32, andthis ratchet wheel also bears against the bracket 168 with the broad face. These faces, therefore, adequately steady the. frame in 006p eration with the two bearings on the rod 65 furnished on the two brackets 159.

In addition to the paper table 13 and the apron 14 for the main part of the platen, the

separately revoluble part 28sthereof has a guide them down under and up in front of the platen. This apron is thus made in one piecein order to secure a perfectly smooth" surface for the tally-strip 25 and the carbon sheet thereof to go around together. It is: held somewhat tightly to thebrackets 159 by screws 170 (Fig.16), which pass through a turned-up extension 171 of said paper table just outside of each bracket 159.

1 The paper table 13 and'apron 1 1 of the 'main platen extend clear out to the righthandend of the carriage, and the auxiliary paper table 1 69 lies inside of these and is slightlyshiftable on its screws 170, thus allowing the auxiliary table 169 to be swung either against the platen to allow a work sheet to pass behind with the utmost freedom, or else to be swungaway from the platen to allow its tally-strlp and its carbon I strip to be threaded through the platen.

' In order, to prevent the separately-revoluble part 28 of theplaten from endwise rmovement,it is provided with a hub 172 bywhich itis journaled on the platen axle 2,

1 said hub bearing against the inside of the end plate 3- of the platen frame. The main part of the platen is prevented from slipping in the opposite direction by means of the usual hub 17 8, which bears against the adj acent end plate of the platen frame. In

order-tokeep the two parts of the platen suflic-ientlyand accurately spaced from each other, to protect the overhanging portion of the rubbersurface 158, thesleeves 150 and l52jare provided with short hubs 174:, which have narrow bearing surfaces and therefore turn with little friction oneach other.

Variations may be resorted to within the scope of the invention, and portions of the :improvements may be used without others.

Having thus described my invention, I.
