Specification of Letters Patent.

@a'tenteai Jan. 5, mos.

To all whom it may concern:

Be it known that I, JACOB FELBEL, citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful improvements in Type-Writing Machines, of which the following is a specification.

My invention relates more particularly to the ribbon mechanism of that class of typewriting machines employing a vibratory ribbon carrier or ribbon vibrator which normally maintains the ribbon awayfrorn the printing" oint and is automatically'rnoved or car so to be thrown to bring the ribbon opposite the printing point when the printing keys are operated;

Rlhe main object or my invention is to provide means for varying the throw of the ribbon vibrator so as to bring different Width- Wise portions or fields of the. ribbon o posite the printing point on the platen at will My invention may be employed to especial.

advantage with ribbons which are divided into longitndinal fields having different characteristics or colors, but said invention may also be used with ribbons of uniform character thron hout in order to more thoroughly exhai st the ink from such ribbons.

To the above-and other ends my invention consists in the features of construction, coinbinations of devices and arrangements of parts hereinafter. described and particularly pointed out in the claims. 7 L

l have showniny invention as appliedto a Monarch typewriter wherein there is employed an operating lever that is connected at one armwitli the ribbon vibrator and at the other arm through an actuating link with a key actitateduniversal bar and lever."

In carrying out myinvention 1 fulcrum the operatin lever in a vertically movable ii lcri m bloc I or member, the vertical position of said block being controlled by a rotary device or earn member which is adirstable at will from the front of the machine,

' though it maybe operated as well from the side of-the machine or from any other point convenient vtor the 1 ser. The rotary device or cam member also gr ides and controls the actrating link which 'is adapted to be connectedwith the operating lever at one or another-of a pitrality of points disposed longitudinalsly of said link.

By means of the devices just briefly described I am enabled to control end vary the normal position of the operating lever, ribhon vibrator and therrbbon without chang ing the normal positions of the devices for actuating them, with the result that while the throw or amount of movement of the ribbon vibrator isalways the same, yet the points at which said movement begins and code may be altered so that different widthwise portions of the ribbon may be-presenied to the types.

While I have shown one form of my invention as embodied in a Monarch. machine it is to be understood that the varior s features of said invention in whole or in part may-be adapted to other forms of Writing machines.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of a typewriting machine embodying my invention, parts of the machine being omitted and parts broken away. Fig. 2 is a traginentary sectional view corresponding with Fig. '1 but showing various parts of the rib- I bon mechanism in different relations from those in which they appear in si rig. 1. Fig. 3 is a transverse vertical sectional view of the machine taken on a plane forward of the top plate, parts of the machine being omitted and parts broken away. Fig. 4 is an. enlarged perspective view with parts in section, the view showing parts of the'ribbon mechanism in the same relations in 'which they appear in 1. Fig. 5 is an enlarged detail sectional view of a parthere- I inal'ter termed a fulcrum member or fulcrum block, said figure also showing the,

mounting of said blockand a part of the operating lever for the-vibrator.

In the drawings, the base 1 of the machine is surmounted by corner posts 2 which in turn sustain a top plate 3. A front plate 4 extends across the front of the machine and is secured to the front corner posts by screws 5. Key levers 6 are iuicrunied on al 'ulc'rurn plate 7 1n the rear of the base and eachhey 'iever is provided with a restoring 'snringS.

A sub-lever 9 is pivoted at 10 to each key lever, said sub-lever being slotted at its lower end portion to cooperate with a hXed abutment 11 and beingconnected at its upper end by a link 12 with a type bar 13, said type bar being nivotally mounted in o. hanger is secured by a screw 15 to a segmental type bar support 16. The type bar 1 ing shaft 46, said driving shaft extending hangers are mounted in segmental series at the Iront of the segment 16 and thetype ends or said type bars are supported on a segmental type rest 17. The type bars are adapted to cooperate with the front lace of a rotary platen 18 mounted in a laten carriage comprisingside bars 19 an a rear bar 20. The top and bottom faces of the rear bar are formed with grooves to receive antifriction balls 21, said balls also cooperating with grooved guide rails 22 nxed to standards Z3 rising irom the top plate. A carrlage teed raclr 24 is mounted on the carriage and normally meshes with a feed pinion 25 I operatively connected with a toothed es-' capement wheel 26. Cooperative with the escapement wheel are escapement dogs 21 mounted at the top of a vibratory dog carrier or T00R81 28, said rocker having a horizontally disposed arm 29 which is connected by a link 30 with an arm or lever 31 projecting rearwardly irom about the middle of a rock shalt 32 pivoted 'on screw pivots 33 secured in the sides of the base. The rock shalt 32 and arm 31 are part of a universal bar frame which comprises in addition side arms 34 and a universalbar proper 35 eytendingirom side to side ofthe mar chinel beneath the series of Key levers and joining the side arms 34 and the central arm .anism of the Monarch machine.

bon spool is operatively connected with a 1 31. The universal bar frame is provided with the usual restoring spring (not shown);

The carriage is provided with a downwardly extending lug or pin 36 which is connected by a band or strap 3] with a spring drum 38 which tends constantly to draw the carriage leftward over the top plate. W hen the printing keys are actuated the escapement devices cooperate in a known manner to ermit the carriage to move leftward or in etter space teed direction a letter 'space: distance at a time.

, hibbon spools 39 are mounted above the top plate one at each side of the machine and forwardly of the platen, said ribbon spools receiving a ribbon 40 which, in the present instance, is shown as divided into two longitudinal fields or stripes a and b of different characteristics; that is to say, the field a may be of one color such as black and the field b of a diife'rent color, such as red for example, or the iield a may be impregnated with copyshown in the drawings being the usual mech- Each ribsmall beveled gear 41 which meshes with a beveled pinion 42 fixed to the front of a horizontal shaft 43, at the rear of which is a terior of said member is threaded to cotravel of the carriage in a letter space feed direction,- the connections comprising beveled gears '47 and 4,8, the former operativcly connected with the spring drum by the usual pawl and ratchet (not shown) and the latter mounted on the driving shaft and connected to the latter bythe usual pin and slot connection so that while the pinion 48 and the driving shaft always turn together, said driving shaft may be moved endwise without affecting said gear 48. The back and forth .endwise movements of the shaft 46 serve to connect one or another of the driving pinions 45 with its associate pinion 44 and thereby to turn one or the other of the ribbon spools 39 to wind the ribbon 40 thereon. That portion of the ribbon which extends between the spools passes through and is uidedby a vibratory ribbon carrier or rib on vibrator 49 which is supported and guided on the upright arms 50 of a guide bracket 51, said guide bracket being secured to the. top plate by screws 52. The lower end portion of the vibrator is bifurcated and the arms 53 of the bifurcated portion are curled or bent to receive and hold across pin 54 which works in the slotted forward end of an operating lever 55, the cooperation being such that the vibrator and its operating lever may always be moved freely relatively to each other. In the present instance the operating lever, instead of having a fixed fulcrum as is usual in (he Monarch machine, is fulcrumed on a fulcrum pin 56 which is carried by a fulcrum block, plunger or slide 57, the lattter, as best shown in Fig. 5, being cylindrical in form and being formed with a kerf or slot 57 in which the operating lever is received. The fulcrum block isprovided with an enlargement or head 58 which is received in an opening or depression'59 in a guide member 60, said guide member resembling a socket or a' hollow screw. The guide member is formed with an opening which receives the body ortion of the fulis provided with a slot or kerf 62, for a purpose presently to be explained, and the exbeveled pinion 44 meshing with a 'beveled o crate with a threaded opening in the top 65 driving pinion 45 fixed to a horizontal drivp ate 3, said member being preferably screwed down into said opening until a flange movements of the operating lever.

63 at thetop of the member contacts with the upper surface of the top plate. The flanged} is formed with nicks or slots 64 to receive a screw-driver or other tool by which the guide member may be readily turned for adjustment or. removal. At either side of the slot 62, the bottom portion of the member 69 is provided with cutaways or notches .65, said notches being oppositely disposed and being adapted to receive the projecting portions of the fulcrum pin 56 when the fulcrum block or plunger 57 is raised in the guide member 60, in a manner presently to be described. The shorter rear arm 66 of the operating lever has its top face 67 preferably-flat. As best shown in l ig. 5, the face 67 normally contacts with the'closed end of the slot-57 at the rear thereof so that bodily longitudinal movement communicated to the fulcrum block will also be communicated to the oper ating lever without affecting the normal relation of the latter and the fulcrum block. Forward of its fulcrum the operating lever is inclined downwardly so that it will not be in contact with the forward part of the closed end of the slot 57 during vibratory The arrangement is such that the fulcrum block serves as a stopffor the rear arm of the operating lever but not for .the forward arm. It does not act as a stop forthe forward end of the lever inorder that there may be no sudden. arrest of and shock .to the finger in the upward or printing movement of the lever. If desired, however, the lever may be stopped in its upward 'throw. I prefer, though, if any such stop he used that it be an adjustable one whereby the throw of the ribbon may be nicely regulated. Such a stop is shown in connection with Fig. 5 and consists of a lip 67 extending laterally from the shorter arm of the operating lever and a screw 67 b arranged in an arm 67 formed on i or attached to one fork of the bifurcated end of the fulcrum block 57.

In operation, when the operating lever is pulled down the lip strikes the point of the screw and limits the upward throw of the lever and the ribbon. 'lhese devices are operable in' both positions of the fulcrum block and the stop screw 67 may be adjusted to regulate the extent of the throw. Thus it will be seen that the upward movements of the ribbon vibrator and its operating lever may be limit ed for each field-of the ribbon so that there may be no overthrow of the ribbon,

-thus insuring the striking of the types on that field only which may be adjusted for use; \Yith a positive stop such as just (|e-,

scribed it is desirable to employ a yielding connection somewhere between the finger key and the stop, an example of which may be seen in my prior patent No. 674,312, dated May 14th, 1901. Adapted to engage with w the top face 67 are two laterally projecting actuating devices or lugs 68 and 69 formed i one above the other at the upper end portion of an actuating link 70, which link is pivotally connected at 71 with the central arm 31 of the universal bar or lever frame. The body of the link 70 is preferably round in cross sect-ion but the upper portion from which the lugs 68 and 69 extend is preferably square in cross section and is adapted to be reciprocated in a guide opening or slot 72 formed in the horizontal portion 73 of an t the underside of the top plate and suitably secured thereagainst.

to be raised or lowered in the guide member to vary the normal position of the operating lever 55 and ribbon vibrator 4-9, and the link is adapted to be switched or shifted to enable either of the engaging or actuating devices 68 and 69 to cooperate with the rear arm of the operating lever, the lug 68 engaging with the lever when the latter is normally in its lowermost position and latter is in its uppermost position. 'lhe preferred means for shifting the operating lever 55 and switching the link 70 will now be described in detail. Arranged below the fulcrum block 57 is a rock shaft 75, said rock shaft being journaled in arms or lugs 76 (1* ig. 3) depending from the under. side of the top plate, one near the right-hand side of the machine and one near the middle thereof. Armsor cam pieces 77 are provided with col' lar portions 78 through which the rock shaft '7 5 passes, said arms 77 being secured in fixed relat on with the rock shaft by pins or. rivets 79 passing through the collar portions 7 8 into the'rock shaft. lhe upper portions of the arms 77 are provided with cam slots 80, each cam slot having a dwell .81 at the rear end and a dwell S1 at the front end, each cam slot and its dwells proiiding a continuous opening which receives one of the projecting end portions of the fulcrum pin 56. Of course other projections or lugs on the fulcrum block, but not connected withthe fulcrum pin, might be employed to engage the cam slots if preferred. Arranged between the arms 77 is a curved cam late 82, said cam l plate being provided'wit ears or tabs 83 which are suit ably secured to the inner walls of the arms 77, as by rivets 84. -'lhe curved cam plate 82 is provided with angularly disposed cam slots 85 and 86 which are joined by a dwell 87, forming a continuous opening I which is adapted to receive the upper portion .tof the link 70 below the rear arm 66 of the l operating lever.

l It will he understood from what has been said and from an inspection of Fig.4 that the l arms or cam pieces 7 and the cam plate 82 The fulcrum block or plunger 57 is adapted the lug 69 engaging with said lever when the angular guide bracket 74, depending from which guides and supports the fulcrum in the front plate 4, the end of said IO( oint. P

constitute a rotary cam member and so port block 65 and the operating lever 55 and also guides the link 70. The rotary member, comprising the arms 77 and plate 82, is adapted to turn with the rock shaft 75 about the axis of said rock shaft as a center, in order to raise and lower the operating lever 55 and vary its relation with the actuating link 70. The de vices for controlling the position of the rotary member comprise a crank arm 88 having a collar portion 89, which is secured by a pin 90 to the rock shaft 75 at the right of the right-hand cam piece or arm 77. The crank arm 88 is pivotally connected at 91 with a push bar or rod 92, the front end portion of which passes through and bears in an opening being provided with a finger button 93. A spring detent '94 is suitably secured, as by a screw 95, to the back of the front plate 4 and cooperates with notches or depressions 96 and 97 to maintain the push bar 92 and through it the rotary member and the parts controlled'thereby in adjusted positions.

Referring now to the operation of the mechanism and assuming that the parts are normally related as illustrated in Figs. 1 and 4, it will be understood that when the universal bar frame is depressed by the printingkeys, it will draw the link 70 longitudinally downward, causing the engaging device or lug 68 to pull doun the rear arm 66 of the operating lever and to swing the forward arm of said lever upward, the latter carrying with it the ribbon vibrator 49. The parts are so proportioned that this upward movement of the vibrator will bring the upper field a of the ribbon opposite the printing It-will be understood that during this actuation of the operating lever the latter Will turn on the fulcrum pin 56 as on an axle, 'sai'd fulcrum in remaining motionless, seated in the dwel s 81 in the arms 77 and contacting with the rear closed ends of said dwells. When pressure on a finger key is removed the parts are restored to normal position by gravity and the usualrestormg springon the universal bar; but if desired the operating lever may have a separate returning spring. As will be apparent,-with the parts. normally related as in Fig. 1, the throw or upward movement of the vibrator will always be the same in extent and will always start from the same point, so that the ribbon will always be raised to the same height and the t e impressions will follow in a path alon t e upper field or portion of the ribbon an longitudinally thereof.

When'it is desired to make use of the lower field b of the ribbon, the button 93 is pushed rearwardly by the operator, causing the notch 86 to disengage from the detent 94 and the notch 97 to engage said detent, =The they join the dwells 81,

' ceases rearward movement thus communicated to the push bar 92 is equal to the distance between the notches 96 and 97 and suttices to swing the crank arm 88 from the position shown in Figs. 1 and 4 to that shown in Fig.

v2. The turning of the crank arm turns the rock shaft 7 5 and through it the rotary device comprising the arm 77 and the cam plate 82; this movement swinging said rotary device rearwardly to the position shown in Fig. 2. During the first part of the rearward swinging movement of the rotary cam device, the cam 85 will act on the link 79 to swing the upper end portion thereof leftward latter is at the rear end of the dwell 87, said link will have been swung far enough to the left of the o erating lever to disengage the lug 68 entire y from said lever. During this movement of the upper end portion of the link 70, the dwells 8.1 in thearms ercam pieces cooperate with the end portions of the fulcrum pin 56; and as said dwells are struck on ares the centers whereof are coincident with the axis of the rock shaft 75, the inlcrum pin will continue tq rernain at the same distance from said axis and consequently neither the fulcrum block 57 nor the operating lever 55 will be affected. The parts are so proportioned that the front ends of the dwells 81 will not reach the fulcrum pin 56 until after the leg '68 on the link 70 has been swung out of the path of the rear arm of the o crating lever. The earn slots are inc ined so that their forward ends where they join the dwelld 81 are'further from-the axis of rotation than are their rear ends where Conse uently the cams 80 next begin to acton the fulcrum pin 56 and will camthe latter away from the axis of rotation of the shaft 75, lifting the fulcrum block 57 u wardly in the bearing member (it), said fu crum block carrying with it the operating lever and the ribbon vibrator.

During the operation of the cam slots 80 on the fulcrum pin 56 the dwell 87 in the cam plate 82 will be in cotiperation with the link 70, so that the latter will remain unaffected.

When the ends of the fulcrum in 56,- how? ever, enter the dwells 81 whic are struck fromthe axis of the rock shaft 75 as a center,

the rear end of the cam slot 86 will be ready to cooperate with the link 70 and by the time the closed forward ends of the dwells 81 engage with the fulcrum pin the link 70 will have been cammed or swung by the cam coasts '5 slot 86 Iightvvardly back towards the operat: ing lever. After the disengagement, how: ever, of the actuating device or lug 68 on the link 70 from the operating lever, and prior to the subse uent .engagementof the link 70 with said ever, the cams 80 Will have acted in the manner described to lift the operating lQV-iI so that the latter Will enter the kerf or slot 62 and the fulcrum pin will enter the slots or cut-aways 65, and said operating lever will be in the position shown in Fig. 2.

Consequently, when the link 70 is cammed by the cam slot 86 back to normal position the rear arm of the operating lever will be above the lug 68 on thelink 70 and will be engaged by the upper lug or engaging-device 69 "on said link. The various parts will now normally be in positions illustrated in Fig.2, and it wi l be understood that the ribbon vibrator and the Working portion of the ribbon Will have been moved upward to an extent corresponding With the upward shifting movement of the operating lever and its fulerum. Ir", now the printing keys be operated the ribbon will be moved upward in the same manner as before and to the same ex.- tent, but the normal position or the point at which the upward movement begins havin' been altered the upper limit of movement 0 so said ribbon or the point at which its upward movement ceases will have been correspond.-

ingly altered. The arrangement is such that at this time the lower field b of the ribbon will be presented to the types and since the throw or extent oi' movement 1s always the same the types will follow in a path alongwill serve to bringl the upper old a. of the ribbon opposite t e printing point in the mannerhereinbefore described. i Various changes may be made within my envention.
