TYPE-WRITING MACHINE.

Tdtzll whom 2'?) may concern Be it known that .1, Jason Farr-an, citizen 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. v

My invention relates to ribbon mecha: nisms for typewriting mach'ines and its principal object is to provide improved mechanism of the character specified. A

More specifically the object of my raven-i tion is to provide ribbon stop mechanism which is separate from the ribbon throwvarying mechanism, thus permittino" both said mechanisms to 'be independenti y. and; accurately adjusted; and also to provide a ribbon stop mechanism capable of being set, adjusted or shifted; positively to limit the! throw of the ribbon under the action" of the ribbon vibrating-means, which stop mechanism shall be automatically set or adjustedf by the striking of the space key or any of l the printing keys after adjustment of thei throw-varying means, or in other words,l shall be set or adjusted during the operationi of the machine for Writing-which includes. spacing as well as printing. l

To the above and other ends my invention: consists in the features of construction, combinations of devices and arrangements of; parts hereinafter described and particularly} pointed out in the claims. g

In the accompanying drawings, Figure ll is a fragmentary vertical front to rear sectional view of a Monarch typewriting ma chine embodying my invention. Fig. 2 is a horizontal sectional view taken below the top plate and showing parts of the actuating, throw-varying and stop devices for the ribbon. Fig. 3 is a front elevation partly in section oi the stop devices prior to a resetting operation. Fig. 4 is a corresponding view showing the stop devices reset, some parts shown in Fig. 3 being omitted. from Fig. 4. Figs. ii to 8 are operating views,

Figs. 6 and 8 to Fig. 4. Fig. Sis a perspec tive view of parts of the ribbon actuating and stop devices.

The frame of the Monarch machine as appears from Fig. 1 comprises a base 1, posts .2 and a top plate 3, above which is supported an end'wise movable platen l diagrammatically illustrated, said platen being mounted in a traveling carriage (not shown) which is connected by a band 5 with a spring drum 6 so that said carriage is constantly impelled leftward, its movements in this direction being controlled by letter space feeding devices which comprise an escapement Wheel 7 and cooperating dogs 8 and 9 supported on a dog rocker ill connected by a link ll with an arm 12 on a universal bur frame 13 pivotcdat l3" andwhich carries a universal bar 1 1. Said universal bar underlies a set of printing key levers 15, each fulcrumed on a plate 16 and provided with a restoring spring 17. Pivoted at 18 to each key lever is a sub-lever l9 slotted at its lower end to cooperate with a, fixed abutment 20 and connected at its upper end by a link 31. with a type bar 22 pivoted on a hanger 23 secured to the front face of a shiftabletype bar segment l -l, the type bars cooperating withthe front face of the plateni,

The universal bar frame and hence the links l1.and 42 connected thereto are in a Monarch machine also operated by a space bar or key 140 attached to a lever frame 150 fulcrumed on a crossbar 151 and provided at its rear end with contact screws 152 which bear upwardly against a forward extension oi the universal bar frame so that when the space key 140 is depressed the universal bar frame is caused to descend with the links 11 and 42 in the same way as when the key vices which comprise beveled gear; wheels 33 and 33 in such manner.that :when the spring drum turns to advance the carriage in printing direction rotary movements will or transverse movements of said link.

be communicated to the driving shaft 31.

Said driving shaft is movable endwise in a known manner to alternately connect with the beveled gear wheels 29, thus driving the ribbon spools in alternation and feeding the ribbon longitudinally back and forth from one spool to the other.

' A ribbon 34 is wound on the ribbon spools 25 and midway between said spools is threaded through the slots of a vibratory ribbon carrier or vibrator 35 which is slidably supported on an upright guide 36 and normally n:aintains the ribbon. below the printing point. The lower end or stem of the vibrator is pivotally connected at '37 with an operating lever 38 having a fixed fulcrum 39. The rear arm of the operating lever has a slot 40 with which engages an actuating stuid 41 projecting laterally from the top of an actuating link 42 pivotally connected at its lower end-to the arm 12 of the universal bar frame. A coiledspring 43 constantly urges the link 42 to swing rearward on its pivot and the swinging movements of the link are suitably controlled by a stationary guide 44 which prevents lateral The spring 43 codperates with a link-con-fl troller 45 to set the link 42 so itSytQ vary thenormal location of the stud 41 relatively to the fulcrum 39 and thereby alter the extent of throw communicated to the opcrat= ing lever 38, vibrator 35'and the printing portion of the ribbon. The controller 45 is slidablymounted on the driving shaft 31 but is connected to turn therewith, and said controller is provided with three operative faces 46, 4'7 and 48 (shown in Figs. 1 and 2) which are adapted to cooperate with and control .the position of the link 42. The face' and 47 are circular and are concen iq with the axis of the shaft 31, the face 46 aving a larger diameter than. the face 47 ,and cooperating with the link 42 to set it asfimFig. 1 so as to'communicate the greatest throw to the operating lever and ribbon 34 and thus present the lower portion or field b of the ribbon to the types. The operative faces are connected by inclined or cam faces so that by sliding the controller 45 along the shaft 31 the operative faces may be caused to engage at will with the link 42.

Then the lesser circular face 47 is moved-- into operative position the link 42 will be drawn rearward by the spring 43 to engage said lesser face 47 and thereby will positionthe actuating stud 41 at the rear end of the slot 40 so as. to operate the lever 38 and vibrator 35 to the least extent vibrating the ribbon only far enough to present the upper widthwise portion or printing field a to the types. The ribbon fields a and b as herein shown are of different characteristics or colors, the ribbon 34 as illustrated being what is commonly termed a two-color ribbon; but v of course a ribbon having uniform characteristics throughout may be employed, in which case the operating face 48 of the controller is preferably made use of to automatically vary the throw of the ribbon progressively or step-by-step, giving it what is commonly called-the cross feed or' snake feed, awell known characteristic of the Monarch machine. The dperative face 48 is eccentric to the axis of the shaft 31 and at one point has a radius equal to that of the face 46, decreasing until the radius equals that of the lesser face 47, the .con struction being such that when the eccentric face is in use it coiiperates with the spring 43 to move the link 42 back and forth along 90 the slot 40 so that the ribbon will be given its greatest extent of throw at one time. and thence its throw will gradually decrease until its least extent of throw is reached, after which it will again increase, and so forth. y The sliding movements of the controller 45 on the shaft 31 are controlled by operatfling devices which comprise an upright arm 49, the lower end of which is bifurcated to loosely en 'age in the grooved collar portion 45.' of the controller and the upper arm of winch is provided with a hub 50 which is secured to the inner end of a slide rod 51 supported on the right-hand lug 32 and on an additional lug 52 depending from the top I plate. Slidable movements of the rod .51

are limited bystop collars 53 and 54 which cotiperate with the sides of the lug 52. l The outer or right-hand end of the slide rod 51 carries an upright pin 55 which is engaged by the forked arm of a bell crank 56 having a fixed pivot 57 and connected by a forwardly extending link 58 with a second bell crank 59 having a fixed pivot 60. The bell crank 59 has a spring arm'61 which extends forward through a cut-away in the right-hand frontplate 62 and is provided with a finger piece or key 63 and is formed with a tooth or depression 61 which cotiperates with notches 64 in the top edge of the plate 62. The tooth 61 and the notches 64 act as detent devices to maintain the spring arm 61 .and the devices controlled thereby present any one of its operating faces to said link so that thereafter as the carriage the link 42. The link is thus re-set at will Y bracket a sto soas to vary the ribbon vibrator devices. The parts thus far described are or may be of the construction commonly found in the Monarch machine.

In order to limitpositively the upward movements of the vibrator so as to restrict; the printing to predetermined lields of the ribbon, I provide stop devices which co-act with the operating lever, said stop devices being variable to correspond with variations in the ribbon actuating or throwing means and being automatically set by the printing keys, a preliminary operation of certain of the stop devices prior to the resetting of the stops proper being performed automatically by operation of the key (33 that controls the throw varying devices. The stop devices proper are supported on a frame or bracket which, as appears in Fig. l, is L-shaped in vertical cross section and is secured to-the under side of the top plate in rear 0.f,,the vibrator by screws 66, being formed with a vertical slot 67 to permit of the passage and operation-of the lever 38. The front and rear parallel upright portions of the bracket 65 provide bearings for a rock shaft 68 which has secured near its forward end and behind the front vertical portion of said member (ll). As best appears in Fig. 9 said stop member comprises upwardly extending slightly diverging arms 7 0 and 71 unequal in length, which at. their tops are bent inward toward each other providing overhanging stops numbered respectively 72 and 73, these stops being directed to cotiperate with the top edge of the operating lever 38 at dilferent points in its path of travel and a short distance behind the vibrator. The operating lever vibrates up and down in the space between the stop arms and 71. The lower end portion'of the stop member 69 below the rock shaft 68 is provided with two notches 74 and 7 5 with which coiiperate a spring detent 76 secured by a screw 7 7 to the bracket 65. The notches and cooperating spring detent 76 provide detent devices which maintain one or another of the stops 72 and 73 in operative position over and in the path of the operating lever 38.

The stops 72 and 73 are rendered operativc by devices which automatically turn the rock shaft 68 to and fro, said devices comprising a rocking lever 78 which is secured to the rear end of the rock shaft 68 forward of the rear vertical portion ofthe bracket 65. The lever 78 is substantially horizon tally disposed and its oppositely disposed Larms terminate in upright extensions 79 and S0. Actuating devices are provided for acting on these extensions to rock the shaft 68 .back and forth and swing one or another of fthe stops 72 and .73 to operative position. Said devices comprise horizontally disposed fingers or actuators 81, 82 and 83 which are I fixed to and extend forward from a slide bar 84. Said slide bar is horizontally disposed and its inner or lefthand portion is slidably supported in a bearing block 85 suitably Zfixed to the link 42 somewhat below the ';upper end thereof. The block 85 is formed with a vertical slot in which the slide bar 84- is' seated, and with a connecting horizontal slet 86 which provides a passage f er the yactuators Si, 82 and 8;- when the bar 84 is yslid endwisc. Said actuators are bent or pit-set near the slide bar 8 so as to clear the lower front portion of the block 85 and iregister with the slot. 86. By sliding end- ,wise the bar Ell-one or another of the actu- =iators may be brought over the upward extensions on the lever 78 so that thereafter when the link 42 is lowered by one of the printing keys the stop carrier or rocker com- ,prisi'ng the elements 78, 68 and 69 may be ,roeked or reset to reset the stops proper.

; Endwlse sliding movements of the stop controller, comprising the slide 84 and the }actuators thereon, are obtained by connerting said controller with the slide. rod The right-haul end portion 87 of the bar 84 is bent upward and is provided with a 5 vertical slot 88 which receives a pin 89 fixed 1 to and extending horizontally forward from ,the hub 50. The construction is such that i when the slide rod 51 is slid in and out by operating the key 63 the stop controller is correspondingly slid or moved endwise through the block 85 without moving the link 42 which supports the same; but when i the link 42 is o erated by the rioting keys 1 the stop controRer will he carried bodily up and down with the link (with possibly, on occasion, a slight pivotal motion around the ipin 89) transversely of the direction of the sliding movement of the controller 84:, this bodily up and down movement being guided in part by the pin 89 but taking place independentl of movement of said pin and the ;parts with which the same is connected. 1 Also when the link 42 is swung fore and aft longitudinally of the operating lever the stop controller 84 will participate in this f movement without variation in its relation- 5 ship with the link, but this movement of the lcontroller will move it lengthwise of and inde endently of the pin 89. The actuators on t e controller are of such length that I they will never be carried backof the plane 1 of the lever 78.

l Assuming that the parts are in the relaextension 80, rocking the lever 78 and tionships shown in Figs. 1, 2, 3 and 9 it will be observed that the link 42 is engaged with the operating face 46 and that the stop 72 overlies the operating lever while the actuator 82 overlies the extension 80 on the lever '78. If now the space key or one of theprinting keys be operated, it will depress the universal bar 14, pulling down the link 42, said link carrying bodily with it the slide bar 84, causing the actuator 82 to push down on they through it the rock shaft 68 and the stop member 69 to the position shown in Fig. 4,

in Whichposition the stop carrier or rocker comprising .the stop member 69 and the lever 78 will be held or maintained by the Y position carries the lower stop 72 out of spring detent 76 and the coiiperating notch 174, said detent ridi'n N out of the notch 7 5 and lntothe notch This swing of the stop carrier from the Fig. 3 to the Fig. at

operation and swings the upper stop 73 intot-he path of the advancing operating lever 38, which lever will be arrested in its up-' ward swing after it has moved the vibrator i upward to present the lower ribbon field 5 to'the action of the types. The stop 73 positively arrests the operating lever and vibrator so that overthrow of the ribbon is prevented. It will be understood that the stop 73 will remainset inv theoperative or inward until the link controller 1-5 has been Fig. 4 position during and unaffected by subsequent operations of the printing keys, until it may be desired to change ribbon fields. Supposeit be desired to shift from the lower'ribbori field to the upper ribbon field a,'the operator pushes the key or finger piece 63 leftward until the lever arm 61 reaches theldbtted line position 3 in Fig. 2, in whichposition the lever arm will be arrested by the tooth 61 cotiperating. with.

the middle'inotch. 641. During this movement of the key and lever arm the connected parts will move correspondingly and the bell crank 56 will move the slid e'rod 51 slid along the. shaft 31 to bring the operating face 47 into cotiperation with the link 42, said link being thereby reset so that the stud 41 will be at the rear end of the slot 46 in position to communicate the least extent of throw to the operating lever and-vibrator. During this slidin movement of the link controller 4.5, the pin 89 will acton the stop controller 8 to slide the same inward on its bearin block 85 and to reset it in the position shown in Fig. 5-. This movement of the stop controller moves the actuator 82 out of register with the extension 80 and brings the actuator 81 directly over or in register with the ar1n or extension 79, so that if now a printing key be depressed the link 42 moving downward will cause the actuator 81' to operate on the extension 79 notc es to reset thestop carrier or rocker in the Fig. 6 positlon, swinging the stop 72 into the path of the upwardly moving operating lever 38. The result will be that when the operating lever has been swung up so that the vibrator will present the upper field a to the types, said operating lever and vibrator will be arrested positively by the stop 72,

thus confining the printing to the ribbon field e and preventing overthrow.

Whenever it may be desired to make use of the ribbon cross feeding mechanism, as when a plain or uniform ribbon isto be used, the finger piece 63 is pushed leftward to reset the arm 61." in the dotted line position indicatgd by th'eletter z in Fig. 2, the train of connected'devices operating to slide the link controller 45 inward and reset it so that the eccentric operating face 48 is in engagement with the link 42. This resetting of the link controller 45 operates through the pin 89 to reset the slide bar 84; in the Fig.7 position from which it. will be observed that theactua'tor 83 has been brought overithe extension or lug '80 so that when the next printing key is operated the stop carrier or rocking frame will be reset in the Fig.8 position, bringing the stop 73 into the path of the-operating lever 38.

It will be borne in mind that the stop'73 limits the extreme upward movemen'tof the operating lever, and consequently the progressively increaslng and decreasing movefnenfis communicated to the operating lever f'due' 'tothe variable action of the eccentric face 48 on the link 42 will not be'interfered with.

The series of operations above described may, of course, be reversed and in fact the mechanism may be set at any time in any one of its operative positions to bring about desired results.

By my present invention it will be seen that I provide ribbon vibrating or actuat ng devices variable or settable to ibrate the ribbondifferent extents and ribbon stop devices which are auton'latically variable by a different operation from that by which the vibrating devices are varied, the stops being thus varied toco'rrespond with-the variation in the extent of the vibrating or throwing incomes ing; that the stop mechanism comprises a stop controller or setting devices Which are variably set indiniendcntly o? the stops proper, these latter being on a stop carrier adapted to rock or rotate bacl; and forth Wi'ien the sctlable stop controller is operated by the first printing key which may be depressed after the resetting of said stop controller; that the Work of resetting the stop is done by the first printing key, and that the actuation of subsequent printing keys does not all'ect the stops. it being, necessary to reset the controller before a printing key will again become eliective to reset the stops; that; inthe present instance the stop controller til isscttable by hand through the same train of mechanism which operates to reset the ribbon vibrating mechanism to vary the throw of the ribbon; that the particular vibrating device which is rcset in the present instance is a link 42; that said link provides a support for the stop link at printing operation but is settable to vary its normal relationship with the link; and that this variation in normal relationship is effected independently of the stop carrier and also of the ribbon carrier or vibrator.

Various changes may be made Withoutdeparting from the spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent, is

' the operation of the printing keys.
