WALTER J. BARRON, YORK, N. Y., ASSIGNOR TO REMINGTON TYPEWRITER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YORK."

mmwm'rme MACHINE.

To all wii om it may concern;

Be'it known that I, WALTER J. BARRON,

citizen of .the United .States, and resident of the borough of Brooklyn, city of New enabling predetermined widthwise portions York, in the county of Kings and State-of New York, have invented certain new and useful Improvements in Type-Vriting Machines, of which the following is a specifithe character specified.

More specifically one object of the invention is to provide improved meansfor en abling the ribbon to be used throughout substantially its entire width in that class of machines wherein the ribbon is vibrated at the printing operation and more especially in machines which 'employ a shiftable platenp Another object is to provide means for of the ribbon to be employed at will in ma,-

chines of the character referred to thus providing for the use of a two-colorrlbbon- -or one having a plurality of-w1dthw1se fields differing in character.

consists in the features of construction, 'combinatio'ns of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

. In the present embodiment of my' invention I- provide a vibrator which is formed with a slot, theiupper edge of which is stepped, thus enabling the vibrator to be taken up at different po1nts by the oper ating lever inthecourse of its movement. Said operating lever is pivoted to vibrate toward and from the printing point and .is

' also pivoted to swing widthwise of the direction of its, vibratory movement,. the swinging movement being controlled by hand operated means and enabling theopcrating lever togbe normally positioned opposite one or another of the steps on the vibrator.

Both the vibrator and the opcrating lever which engages with it are supported on fixed parts of the machine buttheir actuating or vibrating devices are shifted automatically, when the platen'is shifted to change case, by novel devices which are operated by the platen shifting frame.

To the above and other ends my invention Specification of Letters-Patent. Patented Feb. 20, 1912. Application filed Ianuary 26, 191 1. ,Serial No. 604,780.

Fig. 5 is a perspective view of the handcontrolled means for swinging the op'eratng lever. Fig. 6- is front view in vertical section of the mounting of the operating lever. Fig. 7 is a face view of part of 'a ribbon, showing the courses orpaths followed by the types. I

As appears from Figs. 1 and.2, the main frame of the machine comprises "abase 1, posts'2 and a top plate 3; Abovethetop plate are fixed trackways t cooperating through. anti friction rolls. 5 with a. truck 6 connected by links -7' to a platen frame- 8, which carries a'rotary platen 9. A roller 10 mounted on the platen frame runs on a shift rail 11 mounted on uprights 12 con- .nected by a cross rod or bar 13 from the ends of which depend arms 14 pivotally connected at-theirlower endswith s iftkey levers 15, which whensoperated, raise the shift frame and shift the platen frame and platen on the truck 6 to change case: The truck and platen frame togetherconstitute'a carriage which is urged leftward by a spring drum (not shown), the leftward step-by- "s ep movements of the carriage being controlled by feeding..dev iiws-avhich comprise a rack 16 on the carriage and meshes with a pinion 17 operatively connected with a toothed escapement wheel 18 with which cooperatefeed dogs 19 and 20 mounted at the top of a pivoted dog rocker $21. The dog rocker is connected by a link 22 with an arm 23 fixed to a rock shaft 24:, said rock shaft having crankarnis .25 connected by links 26 to a universalbar 27 underlying a set of key levers 28. -Each key lever is connected by a link 29, le'ver'30 and second link 31 with a type bar 32 pivoted on a hanger 33 secured at the front of a stafiimary segment "'34. "The type bars are Eirmlarly' arranged and are adapted to 006perate with the front face of the platen.

-. 'Ribbon'spools 85, (shown in Figs. 1 and 2) are vertically disposed, one at each side of-the machine, forward of. the platen and belowthe top plate. Each ribbon spool is supported on a horizontal shaft 36 which carries at its rear end a bev'eledgear 37 adapted to mesh with a beveled gear 38 on a driving shaft 39, which is connected with the spring. drum in a lmown manner so as to receive'movements therefrom, and is shiftabie endwise so as to connect in alternation with the ribbon spools and feed the ribbon longitudinally back and forth.

The parts heretofore described are comv.mon to the No. 10 Remington machine with which I have preferred to show my invention as associated, although it is to be understoodthat various features of invention may be employed in connection wit-h other forms of writing machines.

The ribbon 40, which in the present case is divided into longitudinal fields a and b of different characteristics or colors, is

' or vibrator which comprises upright paralguided from the spools over guides 41 and directed inward and rearward toward theprinting face of the platen, being threaded through slots in a vibratory ribbon carrier lel arms 42 connected at their lower ends by' a plate-like body portion -43 which is olfset rearward, as indicated at 43, and ex tends downward behind the type bar segment 34, providing a stem 43". The stem v43 has twovertical guide slots 44 which cooperate with lieaded'guide screws 45 secured in the rear face of the segment 34.

A coiled spring 46 connects the elf-set portion 43 with the segment 34 and tends constantly to pullthe vibrator downward, normally maintaining'the 0111p 1' ends of the slots 44 in contact with th: guiding screws 45, thus retaining the printing portion of the ribbon below the point. I Just below the off-set 43 thefstem 43 is formed with the slot 47, the lower edge of which is horizontal, the upper edge being cut to provide'a plurality of engaging devices or steps numbered respectively 48, 49,

50, 51 and 52. The slot 47 receives the forward end portion of an operating lever 53 fulcrumed at 54 on a rotary member, device or sleeve 55 which bears on a headed shouldered screw 56 that screws up into a lug 3 on the top plate 3. The mounting of the operating lever is best shown in Fig. 6. It will-'be understood that .said operating lever may swing up or down in a vertical plane about the pivotal center 55 and may also swing laterally or transversely of the vertical plane about the axis of the screw or fixed bearing 56 as a center. The rear arm ofthe operating lever is constantly ment with the upper edge 59.

urged upward by a coiled spring 57 which is anchored to a pin 58 on the top plate and normally maintains the forward end portion of the operating lever in contact with the bottom horizontal edge of the slot 47. The

upper edge 59 of the rear arm of the oper atinglever is slightly curved and said rear arm terminates in an upright finger or The actuatinglink is adapted to be moved.

forward and backward toward and away from the fulcrum 54 of the operating lever by devices which operate automatically when the platen-is shifted so as to increase the throw of the vibrator when the platen is in upper case position and lessen the throw when the platen is restored to lower caseposition. Said devices comprise aswin ing lever 63 shown detached in Fig." 4.

3, is pivoted at 64 to the sleeve 55 below the fulcrum 'of the operating lever. The lower end of the swinging lever is provided with 'a rearward voifset 65 formed with a slot 66 through which the actuating'link 62 passes.

aid swinging lever, as appears from Figs. 1 and- The upper arm ofithe swinging lgver is provided with a forwardly curved nose '67. Adapted to cooperate with said nose is a cam edge 68 which forms the rearward termination of an arm 69 fast on the shift rod 13. In lowercaseposition the cam 68 coiiperates with the nose 67 to maintain the swinging lever, as in Fig. 1, thus locating the link 62 in its rearmcst position, the roller '61 being farthest from the fulcrum 54 so that the least extent of movement will be communicated to the operating leverat.

printing operation. -When, however, the platen is shifted upward-as in Fig.3, the cam 68 cams the nose 67 rearward, swinging the lower arm of the lever 63 forward and correspondingly swinging the'link 62 so that the roller 61 will operate nearer the fulcrum 64 and communicate a greater extent 1 of throw to the operating lever so as .to compensate for the-increased throw necessary to elevate the ribbon to cover the print-- ing point on the shifted platen. As stated, the edge 59 has, a slight curvature.

center of the curve is co axial with the cen-- ter about whicl-Qthe linkhfi2 swings so that the forward/,and backwa d. movements oi the roller 61 alo'ngits traclf 59 will not affect the operating'lever.

It will be understood that at printing op- The ,erations the printing keys actthroughthe the same and present the ribbon to the print ing point on the platen. The point at which the vibrator will be picked up will depend on the step on the vibrator which the operating lever underlies. For example, when the operating lever underlies the step 48, it

. will be closely ponnected with the vibrator and the latter will start to lnove when the operat ngdever starts; while if the operating lever underlies the step 51 the operating level will move a considerable distance before it acts on the vibrator. Thus it will be seen that by locating the operating lever under one or another of the steps the extent of throw communicated to the vibrator and the ribbon will be varied at will. In order to so locate the operating lever I provide devices which cooperatewith said lever to' swing it transversely of the vibrator on the bearing screw 56. Said devices, as best appears from Figs. 2 and 5, comprise a slide bar 70 which terminates at its inner end in an upright portion 71 formed with an open vertical slot- 72 which receives and controls the forward end portion of the operating lever 53. The left-hand portion of the slide bar 70 is guided on a fixed bracket 73 and the right-hand-end of said slide bar is piv- Y otally connected at 74 with an upright crank will be observed that the pointer-has the double functions of an'indicator and a stop device. The upper edge of the slide bar.

arm 75 which is pivoted at the rear end of a 'rock shaft 76, the latter bearing in a fixed lug T7 and extending forward and through the right-hand front corner post 2, terminating in a-knurled finger button or key 78-.

Forward of the corner post the rock shaft 76 is provided with an upright pointer 79 which cooperates with indicating

marks

80, 81 and 82 formed on an indicating plate 83 secured to the corner post. A-swinging stop 84is adapted to co-act with the pointer to limit the leftward turning movements of the rock shaft and connected parts but said stop may be swung upward and out of operation so as to permitsaid pointer to co-act with a fixed stop orforwardly extending stud 85, the stud 85 permitting further left-. ward movement of the pointer and rock shaft than does the movable stop 8%. It

70 is provided with a series offnotches 8G whiclnare engageable by the free end of a spring detentST secured at 8S,to the frame of the machine. By turning the key-or button 78 the rock shaft may be rocked to and fro, sliding the bar 70 in and out and swinging the operating lever laterally so as to lovibrator and ribbon.

cate'it beneath one or another'of the steps on the vibrator. There are four operating steps on the vibrator and an additional step 52 which is so located that itwillnever be reached by the operating lever during-its swing and so will provide for allowing the vibrator to remain quiescent during printing operations when it is desired to operate the typewriter for stencil or mimeograph work. The cooperating

detent devices

87 and 86 will maintain the' slide bar and connected parts in set or predetermined positions so that the slotted guide 71 maybe set at will to confine the operating lever between the walls of the guide slot 72 to predetermined paths of. up and down vibration. As stated, there are four steps on the vibrator with which the operating lever co-acts to lift the VV'hen the lever coacts with the step 51 the lost motion will-be greatest and the vibrator will be elevated to its least extent so that the types will follow a path w (Fig. 7) along the upper portion of the ribbon field a. lVhen, as shown in Fig. 2, the operating-leveris located be neath the step 50 the vibrator and ribbon will be elevated to a slightly greater extent and so as to cause the-types toprint along the lower portion of the printlngfield win the path represented by the dotted line in Fig. 7. correspondingly, when the operating lever is

locatedoppositethe steps

49 and 48 the vibrator and ribbon will be elevated so as to present respectively the upper and lower portions of the printing field b to the types and cause said types to follow the paths indicated by the dotted lines 1 and 2 in Fig. 7. Thus it will be seen that I- provide for making use of the ribbon in four parallel paths,- thus thoroilghly exhausting the printing surface.

Each of the color indicating marks corresponds to two set positions of the operating lever. hen the operatinglever is operated under the step 51 the pointer 79 will be in contact with the stop 84'so that ordinarily itwill not be possible to throw the operating lever out of operative relationship with the vibrator. lVhen it is desired to render the operating lever i'noperative,-as for niimeographing purposes or the like, thestop Si is thrown out and the'finger' key 78 turned to bring the pointer or stop 79 into engagement with the stop 85, thus moving the connected parts so as to reset the ope 'i ating lever under the step 52. In the opposite" direction or toward the right the movements of the hand operated parts are limited'by a stop 89 with which the pointer 79 isfadaptedfto conta'c'tj.-

It will be observed. that by my "present invention I provide a vibratoi' which has a single normal position but which is adapted to be vibrated or thrown a 'pliirality of different extents for both the lower and upper case positions of the shiftable platen by improved devices which comprise an op erating lever having a double movement, one a vibratory movement and the other movement transverse of the vibratory movement, the transverse movement changing the normal relationship between the operating lever and the vibrator so that the throw of the lever may be varied The operating lever is shittable to vary the throw of the vibrator and the actuating link is shittable to vary the throw of the operating lever. In other words, there is an element t 6., the operating lever, which is shittal'ile to vary the ribbon throw and which in turn is actuated by devices which are themselvesshiftable to vary the throw. My invention pro vides improved and simplified means for obtaining a comparatively large number, four in the present case, of paths of use \vidthwise of the ribbon so to thoroughly exhaust the ink therefrom.

Various changes may be made without dcparting from my invention.
