Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed March 11, 1912. Serial No. 682,941.

I zen of the United States, and resident of Newark, in the county of Essex and State of'New Jersey, have invented certain new and useful Improvements in,:Type-Writing Machines, of which the following is a specification.

, out the necessity of inspecting index de- My invention relatesto typewriting machines and more particularly to means for controlling rotative movementsof the platen for billing and like purposes.

The main object of the invention, generally stated, is to provide eflicient mechanism by which rotative movements of the platen may be readily effected, and the extent thereof dete'rmined with mechanical accuracy to properly introduce work sheets in the machine without burdening the mind of the operator with calculations, and withvices, etc.

Other objects of my invention, considered from a more'specific point of view, are to provide a construction in which the platen may be rotated by means of a spring to bring a work sheet into position to receive the first wrlting line, for example; to lock a hand actuated device or crank arm, by

which the platen is controlled, against operation until the platen has been operatively 1 movement of the platen takes place; to pro-- Q40 connected therewith; to automatically release said lock when operat-ir e connection betweenthe hand actuated device and platen is effected; to lock said hand actuated device against return movement under the power of its spring so that a work sheet may be properly inserted before the return vide eiiicient means by whiclnan incomplete rotation of said hand actuated member is operative to effect more or less than a single rotation of the platen as may be desired; and to provide means wherebyasingle continuous stroke of a member is effective to "automatically release the lock which holds the hand actuated device against movement. to operatively connect said device with the platen and to more sa d dev1ce and thus turn the platen a predetermined distance.

- To the above, and dther ends which will hereinafter appear, 1n invention consists in the features of construction, aa'rangements of parts and combinations of devices set.-

forth in the following specification and particularly pointed out in the. appended claims.

I have only shown so much ofa typewrit- V ing machine as may be necessary to arrive at an understanding of my invention in its embodiment therein.

In the present instance I have shown my invention embodied in a Monarch machine, although it will be understood that the invention may be embodied in various styles of ty'pewriting machines in which rotative platens'are employed.

The top plate 1 of the machine is supported by corner posts 2, and uprights or brackets 3 are secured to the top plate. These brackets-constitute supports for 0ppo-sitely grooved fixed guide rails 4 in the oppositely grooved faces of which anti-friction balls or rollers 5 are received. A guide bar 6 is rovided with oppositely grooved rails? w iich likewise receive anti-friction balls or rollers 5- in the groovedfaces thereof. This guide bar constitutes a rear cross bar of a carriage from which project for wardly extending endbars or

plates

8 and 8 apertured to provide journal bearings the crown teeth 13 of a line spacing wheel 14 fixed to one end of the platen or forming part of one of the platen heads. A spring pressed detent roller 15 is pivoted on a leaf sprin 16 fixed by a screw 1.7 to the carriage and his (letent roller bears against the line spacing teeth. Any suitable number of line siacing teeth 13 may be provided on the line spacing wheel. In the present instance I have assumed that the line spacing wheel is provided with thirty-three teeth, the number most commonly used;

The construction thus far described coir stitutes part of the ordinary equipment of the Monarch machine.

"In the present instance the platen shaft 9 at its right-hand end terminates a short dis tance beyond the outside of the'end plate 8 as shown in Fig. 6, and the various devices which constitute part of the billing mechanism are in the nature of an attachment which may be readily connected to and disconnected from the machine; operative connections between said devices and the platen being effected through the right-harn'l end of the platen shaft!) as represented in lug.

6. Thus an extension piece 18 is apertured at one end to receive the right-hand end of the platen shaft and a set screw 19 is receired in a tapped opening in the extension piece and bears at its inner end against the )laten shaft to effect a positive connection. between the extension and the platen shaft. The outer end of the extension piece 18 receives a finger wheel 20 secured to the extension piece by a set screw 21 received in a tapped opening in the hub 22 of the finger wheel and hearing at its inner end againstthe extension piece to fixedly connect the finger wheel with said extension. A segmental stop carrier which is designated as a whole by the reference numeral 23 is shown in detail in Fig. 3. This carrier is in the nature of a bracket which is provided with an arm Q24 that extends toward the end plate 8 and terminates in a foot piece 20 by which themember 23 is secured to the end plate Siodthe carriage with the aid of a headed s rew 26. A second bracket arm is also pro-titled with a foot piece '27 secured by a screw 28 to the end plate 8. The member .23 is apertured at 29 to receive the extension 1Swl1-ich passes freely therethrough. The body portion of the member 23 bears against a shoulder 30 formed by an enlarge- Y linewith the body portion of the flange between two adjacent openings 34. A scale 35 extends along one edge of the segmental flange and each index mark of the scale applies to one of the openings, alternate index marks applying-to adjacent openings of the same series. .Thus in the present instance sixty-six openings 33 and 34 have been provided and there are siXty-six'index marks on the scale. It will be understood that by, this arrangement. a comparatively fine adjustment along the scale may be provided, and the adjusted part may be secured in its adjusted position in the openings 33 or 34 without the. necessity of making the openings so small that they might be ineffective to properly secure the adjusted part in position. The part 23 has been referred to as a stop carrier and its purpose, or one of its'purposes, is to provide means by which an arresting stop may be adjustably secured thereto. A stop carrying arm 36 is aperhired at its lower end to receive a reduced bearing portion 37 of the platen shaft extension 18 as shown in Fig. 6. The upper end of this stopcarrying arm is provided with an overlapping portion 38 which ex in- Figs. 2 and 6. This portion 38 of the stop carrying arm is apertured to receive twospring pressed locking bolts 39 and 40. Each bolt is provided with a flange all against which an expansion spring 42 bears, the upper end of' each spring bearing against a bottom wall of a recess in which the spring is contained. A plate 43 is apertured to receive the bottom end of the looking bolts 39 and 40 and to provide a bearing surface for the flanges 41. This plate is connected to a stem 44 which in turn is connected at its upper end to a finger piece 45 by which the plate -13 maybe lifted to disengage either of the locking bolts which happens to engage any one of the locking openings 33 and 34. It will be understood that the staggered arrangement of these openings enables but one of the locking bolts ata time to effect an engagement in an opening. Thus if the locking bolt 39 is in engagement in. an opening 34 then the bolt 40 will be maintained disengaged and will be held againstthe face of the seginent on the metal intermediate the two adjacent openings If on the other hand,

thelocking bolt 40 engagesin an opening 33 then the bolt 39 will not-register with an opening 34 and it will be maintained against tlie fac'e of the segment and out of locking' i the direction of the length of saidarm and towarchand from the axis of the plateni' rh contractile spring 49 is connected at one" end to a pin 50 which projects from said slide and at its opposite end-to 'a pin 51 which projects from' the stop carrying arm 36.

This spring exerts a force to normally maintain a slide at the end of its movement to-' ward the axis of the platen as represented in Fig; .1; An arresting stop 52 projects laterallyfroin theslide 46 and is knurled at the outer end portion thereof, as indi- -w.ill hereinafter more clearly appear.

cated at 53, to form a finger piece by which the slide 46 may be moved towardthe free end of'the stop carrying arm against the power of the spring 49. for purposes which It will be-seen therefore that the stop 52 is an adjustable stop which may be turned with the stop carrying arm 36 around the axis ofethe platen to any one of SIXlIY-SIX' posit ons indicated on thescale 35, and-may be retained in itsadjusted position by one orv the other of the locking bolts 39 and 40 en.- gaging in a corresponding opening in the segmental. stop: carrier or support second fixedstop 54 projects laterally from one side of the stop carrier 23 to effect an arrest of the forward rotative movement of the platen as will'hereinafter more clearly appear. 1

A hand actuated device or crank arm 55 is apertured at 56 (see Fig. 7) and has a small hub 57 projectingfrom one side thereof. This. hub is received on the reduced portion 37 of the platen shaft extension 18 and is free to turn thereon. The outer or free end of the crank arm is provided with a.

laterally extending .finger piece or handle 58 by which the crank arm may be manipulated. This crank arm 55 is arrested in its sition clears the usual margin stops 59 during the travel of the carriage and in't-he dotted line position clears the'usiial ribbon I spools 60 and their holders 31. In no posi tion therefore of the handle. or crank arm between the limits of its extreme rangeofj movement does it interfere with any of tlil parts of the typewrit-ing machine proper, I nor does it at anytime extendto'apoint below the upper surface of the topplate'.

It follows therefore that the crank arnilf nayf at all times --be"; nianipulated irrespectivefof I the position of the carriage in its line of f travel. c a

Multiple gearing is provided intermediate this crank arm and the platen for effecting 1 a greater extent of movement of the platen than is given to thegcrank arm. Thus in the present instance the construction is suchthat a complete movement 'ofthe crank arm through about 120 from the full line tothe dotted line positions shown in Fig. 1 is effective to turn the platen through the multiple gearing a distance corresponding to sixty-six line spaces or two complete revolutions of the )platen it having been assumed that the platen is provided with the line spacing ratchet wheel having tllll't-Yqtlll'lifi teeth. the crank arm is effective to transmit 'two complete revolutions to the platen.

Means are likewise provided which are Therefore a'third of a revolution of" operable at will to etlect an operativecon nection between the crank arm and platen through the intermediate train of multiple gearing. Thus it will be seen that a plate or disk 62, the outline of which is best shown in dotted lines in Fig. 5 and in full lines in I Fig. 9. is provided with ears 63 aperturedw for the reception of headed screws 6% which pass through spacing sleeves 5 and are rceived at their threaded ends in tapped openings (S-l (Fig. 3) in the stop carrier 23. By this means the plate 62 fixedly connected to the stop carrier. This plate (32 is apertured centrally for the reception of the greatest reduced portion 66 of the platen shaft extension 18, the shoulder formed,

by the junction between the parts co and 37 of said extension bearing against the plate 62.

From an inspection of Figs. 5 and 9 it will be seen that the plate 62 is provided with an internal segmental rack, or seginentally arrangedrack teeth 67. which constitute a fixed rack with which a pinion US meshes. This pinion is carried by a spindle 69 received in a bearing opening T0 in a;

carrier 71, which isshown in detail in Fig. 8. This carrier is apertui'ed at T2 for the} reception of thesmallest reduced portion ill, of the platen'shaft extension 18. said car- 'rier being free to turn on said extension.

The carrier is also tapped iltllISVGlStl) as indicated at '7 3 for the reception of a screw 74 which extends throughthe carrier. as shown in Fig. 6, and has its inner end 45 seated in an opening 76 (Fi 7 in the crank arm 55. The carrier is thus connected by the screw 74 for rotative movement wlth the cra'nkarm whereas the pinion 68 receives a bodily movement with the carrier and 'cra1ik arm.

'est reduced portion of the platen shaft extension 18. The pinion 78 is provided with wahub on which is fixed an arm 79. The

length of this arm is such that it extends out-wardlybeyond the periphery of the plate for disk 62. It will be understood therefore that a rotative movement of the crank arm 55 is effective to transmit a rotative movement to the spindle 69 as well as a bodily movement thereof around the axis of the platen shaft, and that this movement is transmitted to the pinion 77 and from the pinion 77 to the pinion 7S. and that the arm 79 receives a=rotative movementcorresponding to that of the pinion 78. This rota-tive movement of the arm '79 is in the same direction as the crank arm 55 but. is at a higher rate of speed, so that, for example, a movement, of the crank arm from the position shown in Fig. 1 to that indicated in Fig. 5 is effective to move the arm 79 in a corresponding direction from the position shown in Fig. 1 to that represented in Fig. 5; The outer end of the arm 79 has a pawl or engaging device 80 pivoted thereto by a headed screw 81.. This pawl has an engaging in a 82 adapted to be received in any of the thirty-three openings or notches S3 in the periphery of a wheel or disk 8%. A spring 85 is fixed at one end. as at 86. to the pawl or engaging device and at its opposite or free end bears against a projection 87 which extends from the arm 79. The tail of the pawl extends beyond the pivot 81 and is provided with a laterally projecting pin 88 for purposes which will hereinafter more clearly appear. It will be. understood that the force of the spring 83 is effective to' force the engaging nose S2 of the pawl toward the axis of the platen and to seat said engaging nose in any of the locking recesses or openings 83 in the disk 8-1. with which it registers. The disk or wheel 8+ has a hub 89 tapped to receive a screw 90 which bears at its inner end against the platen shaft extension 18 to fixedly connect the wheel 8 to rotate with the platen. It

will be understood therefore that when the paw-180 engages the wheel 8t. an operative connection is effected between the crank arm and the platen through the train ot intermediate multiple planetary gearing; the

in Fig. 1.

crank arm being connected to the gearing -j at one end of the train and the arm 79 and pawl 80 being connected to the op osite end 1 of the train of gearin It will a so'be' un- 5 f ged from the wheel 84 the crank arm 55 is d1sconnected from the platen and a move derstood that when t e pawl 80 is disenment of the crank arm at this time is ineffective to transmit movement to the platen.

I have provided simple and efiicient means whereby an operative connection can be effected between the "crank arm 55 and the platen, and have also provided means whereby this connection must necessarily be effected before movement can be transmitted to the crank arm. Thus itwill be seen that a releasing or controlling device, which is designated as a whole by the reference numeral 91. is in the nature of a lever of the first order ivoted to the crank arm on a shouldered pivot screw 92. This lever extends in the general direction of the length of the crank arm and is provided at its outer end with a laterally extending cated in Fig. l, for example, is operative to engage the finger piece 58 on the c "ank arm so that a further forward movement of the finger piece 93 is effective to carry the crank arm 55 with it around the pivotal axis of the platen. A leaf spring 94 is fixedly con. nected at one end, as at- 95, to the lever 91 and bears at its free end against a pin 96 which extends laterally from the crankarm 55. This spring tends to maintain the lever 91 in its normal position witlrreference to the crank arm as shown in Fig. 1. From an inspection of this figure it will e seen that the lever is limited in its movement to the normal position by a pin 97 which projects laterally from the-crank arm 55. The lower end portion 98 of the lever 91 is ar- "anged substantially in an arc of which the axis of the platen is the center. This arm is bent laterally to provide a contact edge which cooperates with the laterally "projectingpin 88 on the tail of the pawl 80 when the parts are in the normal positions shown It will be understood that the power exerted by the spring 9i is greater than that exerted by the pawl actuatmg spring so that when the parts are in the normal posit-ion, shown in Fig. l the lower end of the lever 01 will bear against the pin 88 and maintain the pawl S0 ,..against the pressure of its spring 85 and out of engagement with the wheel Set. It will be seen therefore that a forwarlmovement exerted on the finger piece 93, when the parts are in turn the lever 91 around its pivot 92 and to effect a rm'n'emcnt of the lever independentlv of the crank arm. This movement of the lever is efi'ective'to more the engaging the normal. positions. will. be effective to a portion 98 of the lever awayfrom-the axis oftheplaten and to the position represented Fig... 4.

This movement of the contact Qar'm'QS enables the spring 85 to effectan enzagernent of the pawl 80 with the Wheel 84.

"llnsfengagement will take place no matter at what line space position the platen has been arrested in, since there are as many engagmg notches 83 (thirty-three in the present instance) as'there are teeth in the line spacing-wheel, so thatat any line space pop platen one of the notches 83 will be brought into register with .ithe e'ngaging nose 82 of the. pawl 80.

sitlon of arrest of the In order to insure a'proper operative conn'ection being eflected between the crankarm 55 and the platen, by releasing the pawl 80 and effectln' an engagement between-gsaid pawl and it ie wheel 81 before motion is transmitted to the crank arm 55, I have provlded means for locking the crank "arm .against'movement until the crank ,arm has: been operatlvelyconnected with the platens These means. in the present instance 00m prise a locking latch 99 which is in the naturenof'an angular lever pivoted at 100 on the crank arm 55, and provided with an engaging nose 101 which is adapted to engage one end102 of the segment. 32, when the parts are in normal position, as shown in Fig. 1.

From an inspection of Fig. 2 it will be observed that the engaging portion of the locking pawl 99 is oil-set from the body portion thereof. This is in order that the engaging portion of the pawl may cooperate with the end 102 of the segment when the parts arein normal position, or may ride along the upper face of the segment when the locking latch is moved to the releasing position and the crank arm is shifted from its normal position, as will be understood from an inspection of Fig. l. The control of the locking latch is anton'laticallv effected through the actuation of the controllinglever 91. Thus said lever provided Witlia laterally projecting pin 103 which extends through a slot 104 (see Figs. .2 and 7) in the crank arm This pin likewise extends through a slot 10$) (see Fig. 4-) to effect an operative connection between the and and the controlling lever 91. It will Be understood therefore that when theparts are inthe normal positions represented in "Fig. 1, the handle or crank arm is locked against actuation by the latch 99,- the spring 94 of the actuating lever at this time main- 'taining such engagement through the con nection between the lever and locking latch,

'VVhen, however, the lever 91 is movedindependently of the crank arm from the [i01- sition shown in Fig. 1 to that indicated in Fig. 4, an operative connection bctweenthe crank arm and the platen is effected in the manner hereinbcfore described This same movement of the lever 91 is effective to move the 1atch99 to the position shown in Fig. 4.-, thereby releasingit from locking engagement with theend 102 of the segment 3 2. When the finger piece 93 on'the controlhng lever reaches the position shown in Fig. 4, said finger piece engages the finger piece 18 on the crank arm 55 and a further continuous movement of the finger piece 93 is effective to carry the crank arm 55 alon with the lever 91 around the axis of the platen, as shown in Fig. 5. This movement of the parts is effective to bring the locking latch or pawl 99'over the segment 32 which prevents a return movement oft-he lockin latch toits normal position with reference to the crank arin'55, and also'prevents a' restoration-of the controlling lever 91 to its normal position \vit-lrreference to the crank arm 55. "It-followstherefore that the rela-, tionfof the locking latch 99 *and lever 91 relatively to the crank arm as the parts are shown "inflFig. 5 for example, is main "tained throughout the forward and back- \\'ard"strokes ofthe crank arm and until its normal position shown in Fig. 1. When thisrposition has been attained the locking latclr-will again engage the end 102 of the segment, and the movement of the locking latch'which effects such engagement enables the controlling lever 91 to be restored to its normal position relatively to the crank arm, and enables the pawl 80 to be automatically released from engagement with the wheel crank arm from the platen. 5

I have hereinbefore pointed out that the crank arm is limited in its fOlfWlll'dvtlIltl bacluvard movements by the coiiperation of the crank arm with the forward and rear stops 52 and 51 'i'espectively. The crank arm 55-is provided at its forward edge with a lmok-likcimember lOti having a cam face 10?. As the crank arm is moved forwardly from its normal position the can] face 107 is eventually brought into engagement with the stop The effect of this engagement operative connection with upwardlj' 40 which stop and edge of the crank arm; 55Pabnts the stop 52 and fnrther forward movement of the crank arm is .arrested. At the Same time. the hook 100 engaging the stop \vill prevent a resuch time as the crank. armrhas returned to is to cam the stop. together with the plat 84, thereby automaticallydisconnecting the positions shown in this figure the forward I Thus it will be seen that a coiled spring 10.8

is secured at its-inner end by a screw 109 to the carrier 71 by which the

pinions

68 and 77 are carried. The opposite end of this.

spring is fastened to a hook-like member 110 carried by a drum or casing 111, the diamo eter of which corresponds. substantially to the diameter of the disk62. The drum is I open atboth ends and is seated at one end in the peri hery of the disk, preferably by an interloc ing engagement with the ears 63 which project therefrom Headed screws 112 are employed to fasten the drum to the disk 62 In this manner the outer end of the sprlng is maintained fixed,.whereas the inner end thereof 18 connected to the carrier 3 71 of the planetary gearing. The force of this spring is exerted through the carrier 71 and the train of multiple gears to turn the crank arm 55 around the axisof the platen to the normal position where it engages the stop 54 as shown i Fig. 1. The power of the s ring is also exerted to effect a forward rotative movement of the platen through the tendency of this s'prin to rotate the arm 79, pawl 80 and the w eel 84 which is en- 40 gaged by the pawl, it having been previousl explained that t e wheel 84 is osi-' tive y connected vith tl e platen. It W1 1 be understood moreoiltpr' that the act of connecting the pa 'l 80 with the wheel 84 is 5 likewise efiecti exto operatively connect the spring with th platen and to render the powerof the spring effective to return the crank arm to its normal position after it has been moved forwardly to wind the 50 ,spring.

The operation of the construction for condensed billing work, for example, is as follows: The parts being in the normal position shown in Fig. 1, the operator will in- .55 troduce the condensed record sheet, bill sheet andinterposed carbon sheet together into the machine in the usual manner and will turn the platen forwardly a line space distance at a time until the bill sheet has reached a position to receive the first line of writing. The extent of this, movement maybe assumed to be twenty-five single line s acesror to correspond totwent -five teeth ofthe line s acing ratchet whee The operator will t en set the stop 52 to the position indicated by the index mark which p'roc'eed to write the bill' or'; invoice, which reproduced throughtheinterposed carbon on the record sheet Yik fter 'the bill has been j completed .the operator will line space, say; twice in order to 'efl'cct a proper space on the record slice-t between'the copy ofithe'last tlsi'posltlonyand the "operator may then;

written bill and the beginning of the nexi' to be reproduced on the record sheet The written bill sheet may then "be removed without disturbingthe carbon or record sheet-.

i he operator may then grasp the handle 93 is effective to operatively connect the crank arm with the platen and to release the locking latch 99 whichholdsthe crank arm 55 against movement. When the finger piece 93 engages the finger piece 58 on the crank arm the two

members

91 and 55 will move together until the parts; are arrested by the engagementof the crank-arm with the stop 52; The etfect of this engagement is to brin about an automatic locking of the crank arm against return movement and against the power of the spring 108. -The forward movement of the

members

91 and 55 in the manner just described is efiective' to wind the spring 108 and to produce a. rearward rotative movement of the platen through the multiple gearing, a distance corresponding to twenty-five line spaces. A. new invoice or bill sheet may then be intro? and move it forwardly. The first portion 1 of this movement, as hereinbefore explained,

duceo, both hands of the operator being free to effect such an introduction of the bill sheet by reason of the fact that the crank arm is locked against return movement by the engagement between the stop 52 and the hook 106. As scenes the 'new invoice sheet has been introduced the operator may release the stop 52.from engagement with the hook 106' and the power exerted by the spring 108 will be efi'ective to return the crank arm to normal position and to 7 turn the platen forwardly a distance of twenty-five line spaces to bring the last introduced 'bill sheet to a proper position where it may receive the first line of writing. The restoration of the crank arm under the power of the spring 108 is effective, when, the crank arm reaches normal position, to automatically bring about a reengagement of the locking. latch 99 with the end 102 of the'segment and to automatically efiect a disengagement of the pawl 80 with the wheel 84. At this'tlme the platen is free to be rotated indefinitely independently of the stop mechanism and independently ofthe billing devices -as ,a whole, the onlypart of the billing mechanism turning with the platen at this time being the Wheel 84; all other parts of the billingmechanism remaining at rest. This enables the operator to proceed with the writing of the last, and properly introduced bill sheet, and When this is complete and has been copied, through the interposed carbon on the condensed record sheet the bill sheet may be removed and a new sheet introduced in the manner hereinbefore described. Y

I haverreferred herein to the fact that the platen isnormally free" to be rotated indefinitely. By this and like; expressions-I mean that normally there is no positive obstruction to limit the rotative movement of the platen, although the usual spring detent 1516 is employed and normally bears against the line spacing ratchet wheel.

From the foregoing description it will be understood that the construction i'ssuch that successive billing sheets may be quickly and accurately introduced and properly positioned with reference to the condensed record sheet with but little effort on the partof the operatorand that there is nothing to burden the mindof-the.ope'ator with in effecting the introduction of successive bill sheets in proper position'relatively to the condensed record sheet and in proper position to receivethe first line of writing on each of the bill sheets. Thus'after the adjustable stop 52 is once set it is merely nee-- essary to pull the handle 93 forwardly by a single continuous stroke when the platen will be turned rearwardly the requisite distance to receive a new bill sheet and the release of the stop 52 from engagement with the crank arm enables the platen to be rotated forwardlv the requisite'distance to introduce thebill sheet and properly position it with reference to the printing line to receive the first line of writing. These operations'may be continued indefinitely or until a condensed record. sheet is filledand a new bill sheet. condensed record sheet andinterposed carbon sheet may be introduced and written upon as before.

Various changes may be made without departing from the spirit and scope of my invention.
