Application led August 17, 1910. Serial No. 577,575.

Beit known that I, HERBERT H. STEELE, a citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a s' ecification. c l

y invention relates to ribbon mechanism for type-writing machines and has for its object the provision of improved mechanism of the character stated.

`More specifically, one object of my invention is to provide improved' devices whereby the use of the ribbon may be dispensed with at will, whenever it is desired to write a stencil or-mimeograph sheet or for any other purpose. v

Another object is to provide improved means for using the ribbon variably. i

ToY the above and other ends, my invention consists in the features of construction,

combinations of devices and arrangements of parts hereinafter described and particularlv pointed out in the claims.

My invention may be adapted to various lrinds of writing' machines but I have preferred to show it as applied to a. Monarch typewriter.

In lieu of the usual vibrator having a single cross pin I provide a vibrator having two cross pins or points of connection for the operating lever. ySaid operating lever is supported .on a spring pressed slidable frame which may be moved back and forth to enable the operating lever to be connected with one or another of the cross pins on the vibrator. The operating lever is adapted to be variably actuated. When it is connected with the upper cross pin on the vibrator, it is adapted to lift the vibrator at printing operation to some extent but not far enough to bring any portion of the width of the ribbon opposite the printing point. Consequently the types will coact directly with the stencil or other work sheet.l Under another and greater actuation the operating lever when connected with the upper cross pin would, if not prevented, throw the vibrator far enough to present the ribbon to the types, but I provide a stop adapted to co-act with the operating lever to prevent the vibrator from being thrown far enough to bring the ribbon into the path of the types, this stop being preferably connected vertical sectional view showing more operating lever and its variable actuating` devices.

My invention will be more specifically described 1n connection with the accompanying drawings wherein- Figure l is a vertical front to rear sectional view of a Monarch typewriting machine embodying my invention, only so much of said machine being shown as is necessary to a clear understanding of said invention.

Fig. 2 is a longitudinal sectional view of a part hereinafter termed a spring plunger, and its mounting. Fig. 3 is a fragmentary particularly the operating lever, the slidable frame supporting the same and the con-v nected stop, the relative positions corresponding with those of Fig. 1. Fig. 4 is a plan view, partly in section, showing the operating lever, the slidable frame or support therefor and the connected stop in the same relationship as in Fig. 3. Figs. 5 and 6 are views corresponding with Fig. 4t but showing different relations of the parts. Fig. 7 is a. plan view partly in section of the manual devices for controlling the variable actuating mechanism for the operating lever. Fig. 8 is a vertical side view, partly in section, of a modification.

tReferring to Fig. l, th'e main frame of the machine comprises a baseportion l1 from -which rise posts 2 supporting a'top plate 3.

Key levers 4 are fulcrumed on a plate 5 located within the base at the rear thereof. Each key lever is provided with a restoring spring 6 and'is connected in the usual or any suitable way with a type bar (not shown) having the usual or any suitable construction and mounting.- The type bars when actuated are adapted to swing upward and rearward and to cooperate with the front of a roller platen 7 diagrammatically illustrated herein.l The platen is mounted on a carriage (not shown) to which it is connected by a band 8 on the spring drum 9.

Let-tervspace movements of the carriage are controlled by escapement devices comprising vertical link 14y with a'central arm 15 of a universal har frame pivoted at 16 in the sides of the base 1, said'v framecarrying a universal bar 1 7 which underlies the key- 19 one at eachside of the machine above the' top plate and forward of the platen. Each l.spool is `supported on a Vertical shaft 20 which .carries at its lower end a beveled pinion 21 meshing with a beveled pinion 22 carl ried at the forward end of a horizontal shaft 23'bearing in stationary lugs 24 and having fixed at its rear end" a beveledv pinion 25.

yThe two pinions are adapted to mesh al-l ternately 'with associate driving pinions secured on a power or driving shaft 26. Said shaft receives rotary motion from the spring drum `9 when the latter turns vto draw the carriage in 'printing direction, the connection between the spring drum and lche power shaft comprising lntermeshing pinions l27 and 28.

The spool turning or ribbon feeding mechanism above brieiiy described is like that of the Monarch typewriting machine but any other suitable ribbon feeding mechanism may be employed if desired..

Midway between` the ribbon spools the ribbon is threaded through a vibratory ribboncarrier or vibrator 30 which may be of any suitable' construction but is of the usual construction, as shown in Fig. 1, except that' instead of aI single'cross pin the stem of the v vibrator is provided with two cross pins 31 and32 arranged one above the other and about fg apart. The Vibrator is adapted to be vibrated up and down on a stationary,

vertical guide 33 by suitable devices including a member or operating lever 34, the -forward end whereof is slotted, as indicated at 34,

. to coperate with the cross pins 31 and 32.

described in detail.

The mounting of the operating lever 34 is of novel construction and will presently be The rear arm of said operating lever is connected with actuating devices, being formed longitudinally with a slot 35 which receives an actuating lpin 36 projecting laterally from the top of a link 37 said link lextending downward and being pivotally connected at its lower end with the arm 15 of the universal bar frame.

It will be understood that when a key lever 4 is actuatedy the universal bar frame will be swung downward, lowering the link4 v37 and causing it to swing the operating lever 34 to raise the ribbon carrier and the printing portion of the ribbon. It will be further understood that the. extent of movea toothed. escapementz member 10 and feed dogs 11a-nd 12, which dogs are supportment ofthe ribbon carrier `may be varied by varying the actuating devices, thisA bein accomplished by swinging the link 37 a out its pivotal connection with the arin 15, thus changing the position of the actuating pin .36 in the slot 35. A draw spring 38 connects thelinks 14 and 37 and tends constantly to swing the link- 37 rearward about its pivot. .The movements of the link 37 are controlled `by a member 39 (Figs.. 1 and 7) which is slidably mounted on the power shaft 26v and A ribbon 18 is wound on horizontal spools is' connected to receive rotary movement from said shaft. The member 39 comprises three working faces 40, 41 and 42 which are connected by cam surfaces. The faces 41 and 42 are different in diameter but are both concentric with the shaft .26 while the face 40 is eccentric thereto. A hub- 43 extends -rightward from the member 39Vand; .is formed'with al circumferential4 groove 44 which is looselyengaged by a vertical'forke'd arm 45 lixed to the left-hand end of a slide rod 46. Said slide rod is supported-on stationary lugs 47 which also provide bearings for i the shaft 26. Fixed to the right-hand end of the rod 46 is a pin4 48 which 1s engaged by the slotted arm Aof a bell crank lever'49 having a fixed fulcrum 50. A link 51 extending forwardbeneath the top plate connects the other armjof the bell crank 49 with an armof a second bell crank 52 which is pivoted vat 53 to the underside of the top plate near v t-he .front of the machine and has an arm `54 extending forward through a slot 'in the right-hand front plate 55. ,The forward end. of the arm- 54 isl rovided with a linger piece 54aby which the ell crank 52 ma be swung on its pivot, thereby operating ft rough the described connections to slide the rod 46 back and forthin its bearings and vary the position of the member 39` lengthwise of the power shaft 26, thus bringing one or another of the working .faces 40, 41 and 42 into coperation with the link 37.

` As is well understood, the eccentric face 40 is employed when a uniform ribbon is'in use so as to vary automatically and progre'ssively the throw of the ribbon .carrier and obtain a crosswise feedin of the ribbon at the same time that it is' ed lengthwise. In the drawing a two-color ribbon 18 is illustrated, said ribbon being divided lengthwise into fields a and b which may, for example',

be respectively black-land red. With such a;

ribbon it is usual to set the actuating devices in predetermined relationships by employing the faces 41 and 42. When the working face 42 is in operation the link 37 will be maintained normally inthe full line .position of Fig. 1, the pin 36engaging the slot'35 near the fulcrum ofthe operatlng lever. If at this time the lower cross pin 32 is lengaged with the operating lever 34, then the printing-'portion of the ribbon will be no1-many i maintained in the Fig. lposition and at printing operation will be lifted so as to present the lower field b opposite the printmg point on the platen. As long as the actuating link is normally held set by the face 42 the ribbon will always be thrown so as to present the lower field b to the types. The positioning member may be shifted by manipulating the finger piece 54* so as to bring the working face 41 into use and then the llnk 37 will be drawn back by the spring 38 to the dotted line posit-ion in Fig. 1 and at printing operation the vibrator will be lifted only far enough to present the upper field a to the types. It will be observed that as thus far described the operation does not differ materially from that of other twocolor ribbon mechanisms heretofore known. In order to provide for the ready Connection and disconnection of the operating lever with the cross pins 31 and 32, said lever and its fulcrum are slidably mounted. The fulcrum pin 56 of the lever 34 is supported on a block 57 which is fixedl to a slidable U-shaped frame or member 58 and projects down from the central portion of the body thereof. Extendin forward from the ends of the body of the rame 58 are parallel end arms 59 '(Figs. 4 to 6) which are formed with longitudinal slots 60. Said slots receive headed screws 61 threaded into the under side of the top plate and serving to slidably support the frame 58 against the under side of said top plate. Pairs of pins 62 and 63 arranged at opposite sides of the screw 61 limit the back and forth sliding movements of the plate or slidable member 58. A draw spring 64 isl connected at one end to a pin 65 on the frame 58 and at the opposite end to a stationary pin 66 depending from the top plate. Said draw spring constantl ward anti7 normally maintains the rear ends of the slots 60 in engagement with the limiting or stop pins 62." When in normal position the frame 58 maintains the operating lever 34 so that it will engage with the vibrator through one of the cross pins. When the frame 58 is slid rearward against the spring 64 said frame carries with it the operating lever 34 which disengages' from the vibrator and enables the latter to be shifted up and down or .re-adjusted so that when the frame 58 is permitted to slide back to normal position the operating lever will engage with the other cross pin on the vibrator.

The means for manually controlling the sliding movements of the frame 58 comprise devices which are shown in detail in Fig. 2, and will nowbe described. The end arms 59 terminate at their forward ends in downward vertical extensions 67 into each` of which is screwed a socket or bearing 68 extending horizontally forward and terminating in a flange 69. The bearing 68 is tends to pull the frame 58 forbearing members 68 are integral with the frame 58 and that when the linger pieces 73 are against the flanges, as shown in Figs. 2 and 4, then pressure applied to either finger piece will causerearward movement .of the frame. The bearing members 68 pass through slots a in the front plate 75, as shown in Fig. 4, so that the back and forth movementsr of the frame 58 and bearing members 68 are not obstructed. The plungers 71 are adapted to coperate with a three-armed lever 76 pivoted at 77 to the under side ofthe top plate forward and somewhat tothe left of the position normally occupied bythe fulcrumy block 57. The lever 76 comprises laterally extending arms 78 and 79, the arm 78 being formed at its end with a downward extension 80 which lies in the path of the left-hand plunger 71 while the arm 79 is formed with a similar extension 81 in the path of the right-hand plunger. The third arm 82 of the threearm lever extends forward and terminates in' a downward extension 83 which is adapted to coperate with the upper edge of the forward arm of the lever 34, serving as a stop to limit upward movement thereof. A flat spring 84 is secured at 85 to the under side of the top plate and underlies the arm 82 which it frictionally engages. The function of this spring is to maintain the threearmed lever in the positions to which it may be swung back and forth under the action of the plungers 7 'Supposethat the parts are 'in the relationships shown in Figs. 1, 2 and '3 and that it be desired to dispense with the use of the ribbon for the purpose of writing a stencil sheet or for some other purpose, the operator first presses the righthand finger piece 73. By reference to Fig. 4 it will be noted that I at rthe beginning of the operation the righthand plunger 71 is in contact with the extension 81 on the lever 76 and that the stop 83 is out of the path of the lever 34 and consequently in inoperative position. As the linger piece `73 is pressed in the frame 58 is slid rearward, carrying with it the operating lever 34 and at the same time the three-armed lever 76 is swung on its pivot 77, moving the stop 83 over and into the the extension 80 against the left-hand i du plunger `71.' As soonas contact between-the extensionl 80 and the associate .plunger takes place, `rearward movement; of said plunger V1s arrested and it is foroedforward in its bearing and compresses -its spring 74, causingA the finger piece 73 to move forward away from the associate ange 69 which at arrested by the stops-63 engaging the Efor# ward, ends of the slots 60. `At .thistime the arts will be in the siti-onV shown in Fig. 5, rom -which it wil -be observed that the operating lever 34 has been-disconnected from the cross pin 32.I Consequently the vibratorA may be lowered until the cross in 31 is opposite the sllotB/iv of the' lever,a er which the'right-hand finger piece 73' 'may b1: released, -permittin `the spring -64 to restore the frame 58 'an the operating lever-to normaly position, the'elot l34l of said lever now` being engagedfwith the cross pin '81, thus giving it a new point yof J'connection with the vibrator andlowering the' normal position of the latter. During the return of the frame 58 and operatin lever to normal osit-ion4 the three-armed: ever 76 'will 'not e fafected but will be maintained in the `Fig.=-5 position bythe friction spring 84.- .39

As "the 4frame, 58 'moves forwardit carries with it the vleft-hand bearing -68 but-'does noi-affect the associate spring plunger 71, although the spring-of said plunger grad` ually 'expande until the ian'ge y69yrengages with the buttonor finger p1ece73. When the parts arev re-arrested' by `the stop 62 they will be in the normal position shownin Fig.

6. It will be understoodthat during the movement ofthe parts vfrom the -Figl to the Fig. 5' position and back .from the Fig.

5 position to lthe Fig.' 6 position, the'link .37 `will not-be affected. Iniorder to preventobstruction of the rearward movement of the leverl 34 by vthe actuating-pin 36 the' slot 35 is extended forward as indicated at 35, said extension; moving back relatively vto the actuating pin when` the frame 58 .is

pushed in or rearward. It willfbe seen that the operating lever has a. single normal position while the vibrator has two'normal positions; further', that the' change in normal 'relationshi between vibrator and operating lever is eli) Y 3 7 and other actuatingdevices. If now any printing keybe voperated the lever 34 will receive its greatest extent of movement,

since the link 37 is in itsforward position;

but-the upward movement of said lever-will be limited by the stop 83 which. will arrest the lever and vibrator before the printing lportion of the ribbon has reached the print- *lng point. In the present instance, the arrest ofthe lever 34 checks the downward movement of the link 37 and universal ybar 1-7 and limits the depression 4of lthe key.

to some: extent but the' ribbon'aopposite ected independently of the linkstead Iof being mountedon a fixed leven so that the same ie prevented from throwing the associate typebar far enough to the .printing point, although of course .the stop member or three-armed lever 76 to Athe Fig. 4 position where said stop is inoperative. .This is accomplished by pressing in the left-handkeyv or finger plece 73 to the limit -of its rearward movement and then ,letting o, permitting-thel` parts to be restored .by t e spring 64:` .As 'a preliminaryp'however, to Ive-setting the stop 83 in inoperative'position, the o erator -must readjustthe positioning member 39 by manipulating the `finger piecei 54a so as to bring the opera-ting' face 41 linto the plane in which the link 37 swings,thus permitting the draw spring 38 to draw said-link back fto the rear of the Aslot 35 as shown by the ldotted line in :.Fig. 1. -The parts -are so `proportioned thatwhen-fthns setthe link '37 lifts the vibrator and printing portion of the' ribbon not farenough to bring the .printing point, the resultubeinggthat-the types, when actuated, willstrikeover the .-topedge of the ribbon and-will eontactdirectlywith the stencil sheet-.or other-work sheet. I

It willrbe lnoted .that the mechanism including'the 4sto -83 and associate parts oonstitutessafety evices which. insure that the ribbon cannot be liftedA to the printing point by'the actuating devices when the 'vibrator is normallyv set in its lowermost osition with the operating lever 34 connecte therewith at the upper connecting point or cross` thestop 83..' The spring plungers provide connections between the frame 58 and the three-armed stop member whereby the stop member-is automatically moved, set or o erated ywhen .the frame is o erated to d1s' connect the operating lever om the vibrator, said frameconstltuting means for changing the relationshi between said vibrator and its operating ever.

'Various changes may be made in my invention and parts of the same may be used .without other parts, all without departing from the scope of said invention. An example of such changes-is shownA in Fig.- 8

wherein the vibrator 86 is provided as beforewith two cross pins 87 and 88, but inide said vibrator coperates with a 'plvoted guide-such as is shown in my pendlng atp; plication Serial No. 571,150,1iled July 9 1910.' The movable part-89 of said guide is pivotalysupported at 90 ito the fixed part 91 of said guide and is adapted to be swung on said pivot 90 so that the ready disengagement of one cross pin and t-he engagement of the other cross pin with the operating'lever may be effected. The operating lever 92 has a slot 93 at its forward end to engage with the cross pins. `Said lever is iu crumed at 94 to a lug or post txedto and depending' from the top plate 3. The rear arm of the lever 92 is formed with'a slot 96 for engagement with the actuating lilik (not shownl. The post 95 is extendeddownward below the lever 92 and has fulcrumed to its lower end at 97 a stop lever 98 which extends forward below the lever 92 and is provided at its forward end with a slotted opening 99 which is at the same distance normally below the slot 93,' as is the distance between the cross pins 87 and' 88, namely,l about 335-5. The lever 98 is provided with an upward extension 100 offset laterally so as not to interfere with the lever 92. The upper end of the extension 100 is adapted to co-act with the under side of the top plate 3 and serves as a limiting stop.

When related as in Fig. 8 with the lower cross pin 88 engaging the slot 93, the parts will operate during the printing movements as in the ordinary construction, the stop lever 98 remaining inoperative. When, however, the vibrator 86 and the guide part 89 are swung about the pivot 90 to disengagetlie pin 88 from the slot 93 and rengage the pin 87 with said slot, the pin 88 will engage the slot 99, thus connecting the levers 98 and 92 to the vibrator. The result will be that through the actuation of the printing keys the lever 98 will be swung upward and if the actuating link is adjusted to throw the lever 92 far enough to present the ribbon to the types, then the stop 100 will contact with the top plate and will arrest the vibrator before the ribbon has been moved into the printing field. If the operating lever 92 receives a less extent yof movement from the actuating link, such that it will not lift the ribbon into the'printing field even if not prevented, then the stop 100 will not come into play. In other words, said stop is proportioned and arranged so that it will only come into action when withoutJ it theribbon would be presented to the types.

Various other changes may be effected without departing from my invention.k y WhatI claim as new and desire to secure y by Letters Patent, is zl. In a typewriting machine, the combination of a ribbon vibrator, an operating .lever connected normally directly therewith,
