TYPE-WRITING MACHINE.

Application filed. January 15, 1915.

To all whom it' 'may concern:

Be it known that l, EDWIN E. BARNEY, citizen of the United States, and resident of llion, in the county of Herkimer and State of New York, have invented Acertain new and useful Improvements in Type- VVriting Machines, of which the following is a specification.

My present invention relates to ribbon mechanism for typewriting machines and its general obj ect is to provide improved mechanism of the character specified. More particularly one object of the invention is to provide new and improved means for varying the vibratory movement of the ribbon so that dierent widthwise portions or color fields may be employed at will; another object is to provide new and improved ribbon sto i devices; and a still further object is to pro de novel devices for dispensing entirey` with the use of the ribbon so as to facilitate, for example, the writing of stencils.

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

In the accompanying drawings,

ward, the views showing the parts in the different relationships in which they may be set.

As appears from Figs. 1 and 3 the main frame of the machine comprises a base 1, Iposts 2 and a top plate 3 which support fixed guide rails t, said rails cooperating through anti-"friction balls 5 with a carriage truck 6. A platen 7 is mounted in a platen frame 8 which is shiftably connected with the truck 6 by devices 9 so that said platen frame may be moved up and down to shift the platen and thereby change case. Said platen frame comprises 'a cross bar 10 on which is journailed a roller 11 that is adapted to run on a shift rail 1Q supported by upright arms 13 rising from a transverse bar 14 which in turn is supported on upright arms 15, each arm 15 being pivoted at its lower end at 16 to a lever 17 provided with a shift key 18. The platen normally stands in lower case position but may be raised or shifted t0 upper case position by` depressing either of the shift kevs 18 which thus control the shifting movements of the platen through the shift frame comprising the rail 12, cross bar 14 and pairs of arms 13 and 15. Printing key levers 19 are provided with keys 20 and are connected by links 21 with sub-levers 22, said sub-levers in turn being connected by links 23 with front-strike type bars Q4 mounted on hangers secured to a stationary segment or support 26. A universal bar 27 underlies the key levers and is supported on arms 2S depending from crank arms 2.9 which project rearward from a transverse rock shaft 30 having end pivots supported in the sides of the base. Projecting from said rock shaft' near its middle is an arm 31 which is connected b v a link 32 with certain eseapement devices (not shown) but which are preferably of the usual construction. Ribbon spools 33 are supported. one at each side ofthe machine. above the top plate on shafts 34 and a ribbon IE5 is wound ony said spools and fed upward therefrom through openings 236 in the lop plate.. thence over stationary guides 37 and through a ribbon vibrator. hereinafter described. arranged centrally between said guides. Wenns for turning the ribbon spools in alternation to feed the ribbon longitudinally back and forth operate on the shafts 34, whirh shafts bear in lugs 38 depending from the top plate `and extend fore and aft of the machine. The ribbon spools are supported on the front ends of these shafts while their rear ends carry beveled pinions 39 which are adapted to mesh with beveled pinions 40 mounted o n a ribbon driving shaft 41 bearing in stationary lugs 42, one pinion 40 being disposed near each end of said shaft. The driving shaft is connected through intermeshing beveled pinions 43l and 44 with a spring drum 45 in such a way that when the carriage comprising the truck 6 and platen frame 8 is drawn leftas best appears from Figs..4, 5 and 6, a

body portion 47 of sheet metal from which depends a narrow integral stem portion 48. The sides of the body portion are curled or rolled, as indicated at 49, to provide tubelike portions which receive upstanding wires 50, the upper ends whereof are bent to provide guide loops 51 through which the ribbon is threaded. The wires 50 are frictionally held in the tube-like portions 49, the

loops 51 and the printing portion of the ribbon which extends between them. The construction provides a vibrator which is simple and inexpensive, is light in weight, and affords a ready relative adjustment between the body and stem on the one hand and the head comprising the wires 5() on the other. The stem 48 at its lower end is curled around and pivotally supported by a pivot pin which is mounted on the forward end of a. horizontally disposed arm comprised in a ribbon operating member or icver frame 54, said frame further including laterally divcrging branches 55 and a central downwardly extending arm 56 terminatH ing in a rolled or cylindrical end portion 57. The branches 55 are curled around and frictionall)r hold a pivot pin 58 which is pivotally supported on a guide frame which is designated as a whole by the numeral 59. Said guide traine comprises two parallel side arms 6!) connected at the top and bottom by inn-gral er ss bars numbered respectively 431 and 62. Extending upward from the cross bar 62 are lugs 63 which are inclined rearward behind the rail 12 and receive screws 64 by which the guide frame 59 is fixed to said rail. The ends or sides of the cross bar 62 terminate in rearwardly bent ears 62 which are formed with bearing openings in which the projecting ends of the pivot rod 58 are journaled. The arms 60 in oline upward and forward in front ofthe rail 12 so that the cross bar 61 is at the front side of the platen. Said cross bar near its ends islcurved forward laterally and terminates in upstanding guide fingers 65 behind which the ribbon passes before it reaches the vibrator, said fingers pro` viding a guide for the ribbon in the vicinity of the vibrator and which remains stationary during vibratory movements of the vibrator and lever. Depending centrally from the cross bar 61 is a lug 66 which provides a support for a headed shoulder screw 67, said screw extending through an elongated vertical slot 68 cut in the body 47 Vof the vibrator. The sides 68 of the slot are formed by bending back the metal from the slot opening so as to provide smooth and comparatively wide surfaces for coperation with the sides of the guide screw 67. 1t will be observed that the guide frameV 59 which. is supported on the platen-shifting frame and shifts with the platen combines several functions, as it provides a pivotal support for the operating lever, a guide' for the vibrator and also guides for the portions of the ribbon which extend from the vibrator to the spools or more directly tothe stationary guides 37.

The operating lever and vibrator are adapted to be actuatedfby an actuator or lever member which is mounted to shift auton'latically when the platen, the vibrator and the operating lever are shifted, but to a less extent than these three elements. In other words, the actuator receives a differential shift. The purpose of this, as will more clearly appear from what follows, is to compensate as between the operatingleverv which shifts with the platen and the element from which the actuator itself receives motion and which does not shift at all. The actuator' or sub-lever, designated as a whole by the numeral 69. is vertically disposed behind the shift bar 14 and is preferably formed of sheet metal, its upper end portion providing a con'iparatively broad face 69 for copcration with the round end 57 of the operating lever. The lower end or arm of the sub-lever has a lateral slot 70 below which the metal bent or shaped, so as to provide at thc left-hand side a step or face 7.1` which is behind the surface or face 72 at thc right-hand side, said face 72 being in the general plane of the sub-lever. The two faces are adapted to copcrate separately with the rounded upper end of a key controlled oi'ierating finger or device 73 which as clearly shown in Fig. 1, rises from the crank arm 31 to which it is fixed by rivets 'being pivoted between its ends.

74. The sub-lever -69 is of the irst order, For this purpose about midway of its length it is provided at its side edges with rearwardly bent, perforated ears 7 which receive and bear rotatably ona pivot pin 76. This pivot pin is supported on a bracket, bearing member or slide, designated numeral 7 7, best shown in Figs. 4 to 7. Said member 77 comprises a horizontally dis- Josed body portion or slide bar proper 78 from the middle of which rises anupright portion 79 terminating at the top in a forwardly bent slotted lip 80 which receives the upper end of a guide finger 81 that is screwed or otherwise secured to the top of the bar 14. This guide finger serves as well to support the slide 77 and prevent it from pulling away toward the rear through'gravity. rl`he portion 79 is provided at its sides with rearwardly bent parallel ears 82 which loosely embrace the ears 7 and support the ends of the pivot pin 7 (3 which project` beyond said ears 7 The body portion 7 8 is provided near its ends with horizontal slots 83 which receive headed supporting and guiding screws 84, said screws being threaded int-o links orv arms 85 about midway of their lengths. Each link 85 is lpivotally supported at its inner end on a shoulder screw 86 which is threaded into the rear of the shift bar 14, the two screws 86 being close together and behind the middle portion of the slide. The outer ends of the links 85 are pivotally anchored at 87 to stationary supports or angular brackets 88 suitably secured to the under side of the top plate and inclining forward and downward therefrom. It will be understood that the outer ends of the links 85 have fixed pivots as distinguished from their inner ends which have shiftable pivots, being supported on the Aplaten shifting frame. The screws or supports 84 are fixed or supported at such points on the links 85 as to receive half the amount of shifting movement which the platen shifting frame comprising the shiftable bar 14 receives when one of the keys 18 is depressed. Consequently the slide 77 which is mounted or supported on these screws 84 wil-l, together with the sublever G9, be shifted differentially or to half the extent that the platen. together with the ribbon vibrator and operating lever, is shifted. In other words, when the operating lever 54 is shifted the full extent of the platen shift the sub-lever G9 which operates on said operating lever will be shifted only half as far and as a result of this the length of the load arm of the lever or .the distance from the pivot 7 6 to the point of engagement with the lever end 57 will be increased. However, the length of the power arm or the 'distance from the pivot 7 6 to the point of enas a whole by thehand front post 2.

`device or actuator 73 to the operating lever 54 through the sub-lever 69. In other words. since the finger 73 has a constant movement communicated to it from the action of the printingl keys on the universal bar, the operating lever 54 and ribbon vibrator will receive a corresponding constant throw or extent of movement in spite of the fact that the vibrator and operating lever shift to change case while the actuator 73 is nonshifting. This result is due to the fact that the device or element 69 which is interposed between the operating .fingers 73 and the lever 54 and transmits movement from one to the other has a differential or compensatory shifting' movement as contrasted on the one hand with the lever 54 which has a greater shifting movement and on the other hand with the finger or lever arm 73 which has no shifting movement. In lower case the links 85 incline downward from their pivots 87 so that they are at an angle below the horizontal lines adjoining said pivots. As a result, however, of the upward shifting movement the links will be swung up until they are at an equal angle above the horizontal line.

The slide 77 is so mounted that it may not only be shifted up and down with the platen butmay also be shifted sidewise at right angles to this movement so as to move the sub-lever back and forth from side to side and bring either one of the steps 71 or 72 opposite the finger 73 for the purpose of varying the ribbon throw and changing the ribbon fields. Also a further lateral movement may be communicated to the slide and sub-lever in order to carry the latter completely out of the field of operation of the finger 73. The means for thus laterally shifting the slide and sub-lever extend to the front of the machine and comprise, as shown in Figs. 1 to 4, a link or bar 89 which is pivotally connected 'at its inner end at 90 to a lug 78 rising from the left-hand end of the slide bar -7 8. The outer end of the link 89 is pivotally connected at 91 to a crank arm 92 rising from and fixed to the rear end portion of a rock shaft 93 that extends fore and aft of the machine at its left-hand side. The rear end portion of said rock shaft bears in an alignlar bracket 94 secured by screws 95 to the under side of the segment 2G, while the forward end portion of said rock shaft 93 bears in a plate 9G secured by screws 97 tothe left- Forward of said plate, the rock shaft is provided with a knurled button or finger piece 98. Behind the iinger piece a pointer 99 projects radially from the rock shaft and 'cooperates with indicati ated type bar.

ing marks vor devices 100 on the plate 96. The middle mark 100 corresponds to the upper field of the ribbon 35 which, in the present instance, is preferably a bi-coler ribbon, the upper stripe or field L being black and the lower field Z) being red. llVhen the pointer 99 is brought opposite the lowermost indicating mark as in Fig. 2 the shaft 93 will be turned so that the slide 77 and the sub-lever carried by it will be drawn to the position shown in Figs. 3, 5 and 8 with the forward step` 72 lopposite the finger 73. The slide and sul)- lever, together with the connected parts including the rock shaft 93, will be maintained set in this position by detent devices comprising a lug or rounded projection 101 on the rear face of the bracket 94. This projection is adapted to coperate in turn with three holes or openings 102 formed in a spring detent plate 103 screwed or otherwise fixed to the rock shaft 93 behind the bracket 911. In the present instance the rightlhand hole 102 is engagedl with the lug 101, thus fixing the rock shaft and through the crank 92 and link 89 setting the slide and the sub-lever in a predetermined position laterally of the finger 73 and the operating lever 54:. With the parts thus arranged, an actuation of one of the printing keys 20 will operate through the universal bar and connections to swing the finger 73 rearward. Normally the finger is slightly separated from the operating face 72 as shown in Figs. 1 and 6 so that there is a slight lost motion before the finger picks up said lever and swings it on its pivot, causing the upper arm of the sub lever acting on the operating lever to lift the vibrator and move it upward to interpose the ribbon in the path of the oper- The parts are so proportioned and arranged that this upward movement will carry the ribbon far enough to present the lower field b to the types; and so long as the parts remain set as described this throw of the ribbon will be constant for each actuation of a 'printing key with the result that the type impressions will follow a straight path` along and centrally of the ribbon field Z). lt will be understood that the shifting of the platen to upper case position and the consequent shifting of the parts, as illustrated in Fig. 5, will not affect the extent of ribbon throw which will be the saine as in lower case position. The ribbon vibrator will be shifted upward with the, platen and to the same extent, so that the nornml relationship between the vibrator and the platen will be the saine in upper ease as in lower case position.

lWhen il, is desired to use the upper field a of the riobon 35 the roelr .shaft 93 is turned thro h the finger button 9S until. the pointer is brought opposite the iniddle indicating mark 190.. The turning movement of the rock shaft acting through the crank arm 92 and the link 89 will shift the slide 77 laterally toward the right. As a result the sub-lever 69 `will be shifted rightward until -the operating face 71 at its lower end will be brought opposite the finger 73, as shown in Fig. 9. r:Ehe face 71, it will be noted, is in, a vertical plane somewhat behind or in rear of the face 72 so that as a consequence of thel resetting the initial lost motion between the finger 73 and the sub-lever will be increased, resulting in less movement being communicated to the sub-lever from said finger. The

face of the upper end 69" of said sub-lever is in a single vertical plane throughout its width so that its fore and aft relationship with the operating lever 54: will not be affected b y the lateral shift. The ribbon throw changing devices will be maintained set in their new positions by the detent devices 101 and 103. the lug or detent 101 being at this time lengaged with the middle hold in the detent plate 103. With the parts thus set an actuation 'of a printing key, acting through the finger 73, will as stated. communicate less movement to the sub-lever, and as a consequence less motion will be communicated to the operating lever and vibrator. The parts lare so proportioned and adjusted that this movement will raise the vibrator and throw the ribbon far enough to bring the upper field a opposite the printing point and into the path of the operated type bar. Since the throw will be constant as long as the parts are maintained thus set and whether the platen is in lower or upper ease position the type impressions will 'follow a straight path lengthwise of the field a and about fentrally thereof.

Should it be desired to dispense entirel \v with the use of the ribbon when the type bars are actuated, for the purpose of writing stencil sheets or for any other desired purpose, the finger button 9S isturued to bring the pointer 99 opposite the uppermost indicating mark [00. this resulting in a turning of the rork shaft and a consequent set-- ting thereof with the detent v)101 engaged with the left-hand detent hole V102. .\s a consequence the slide 77 will be moved to its extreme, right-hand position and the sul lever 69 will be carried rightward past the linger 73 and set as `shown in Fig'. l0. so that at printing operations the linger will move idly without all'eeting the subdever or ribbon vibrator1 these remaining quiescent and lnuintuiniug the ribbon below the printing point.

ln order to limit positively both the up und the down movements of the ribbon rar rier or vibrator when it. is vibratori during printing operations, .stop devices are pio ios body portion 105 which embraces the front and under sides of the shift bar 14'a11d is slidably mounted on said shift bar by headed screws 106. which pass through elongated slots 107 formed in the front wall of said body portion and are threaded into the front of said bar 14. Between the under side of the part 105 and the bottom face of the bar 14 is interposed a flat friction spring 108 (Fig. 7 the ends of which are bent downward and take into holes in the under side of the part 105. There may also be provided a leaf spring 109 secured as by screws to the under face of the bar 14 and having its free end pressing upward against the under part of the body 105. Connection between the supporting frame 104 and the slide 77 is provided by means of an angular finger 110 which extends upward and is then bent rearward from the righthand end portion of the body 105, as best shown in Fig. 4, said finger engaging loosely in a vertical slot 111 cut in a lug 112 rising from the right-hand end of the slide bar '78. The connection is such that the frame 104 is compelled automatically to slide lengthwise of the bar 14 whenever the slide 77 is shifted laterally but the frame 104 and the slide 77 may be shifted up and down differentially when the platen is shifted, the frame 104 participatingin the full extent of the platen shift 'while the slide 77 is shifted to a less extent. Rising t centrally from the body portion 105 integral arm 113 which is bent or ofi'- fmrward, said arm providing a support the stop device proper v114. lnaid stop device is adjustably secured to the arm 113 by pivot screws 115 which are threaded into the arm, and pass through elongated vertical slots 116 in the uprit l t body portion of the device. 114, thus `ing fine up and down adjustments o device 114 in as sembling the mechanism. From the body portion of the device 114 extend leftward two stop arms 117 and 118. The lower arml 117 is provided at its outer end with a depressed portion 119 while the upper arm terminates in a lug 120 which projects downward just to the right of the depressed end 119. The arms 53 of the operating lever extends forward between these two arms 117 and 118. said arms providing stops for positively arresting the operating lever and vibrator in both directions of their movements. Normally the operating lever engages with. the arm 117 which limits its downward movement and also maintains it in proper normal relationship with the platen when the latter is in lower case position, and also supports and raises the operating lever and vibrator' when the platen is shifted to upper case position. Preferably a spring tongue 121 is suitably secured to the under face of the arm 53 and is interposed at its free end between said arm and the stop arm 117 to act as a cushion between the parts and to eliminate noise. lVhen the sub-lever is set as in F ig. 8 to give the vibrator its greatest throw, the bottom edge of the stop arm 118 underlies the arm 53 which will contact with it at the end of the throw so as to insure the arrest of the printing portion of the ribbon with the field opposite the printing point. When the sub-lever is shifted to give the short throw of the ribbon, the stop device 114 is correspondingly shifted to bring the lug 120 over the arm 53, this lug being adapted to arrest the operating lever and vibrator at the completion of the short throw of the ribbonwith the upper field@J opposite the printing point. It will' be observed that while the stops for arresting the printing movement of the vibrator are 1n different horizontal planes, one above the other, the stop arm 117 Y is inthe same horizontal plane for both these throws, so that the normal position of the operating lever 'and vibrator is unaltered by the throw changing operation. However, when the sub-lever is shifted to the Fig. 10 position to provide for mimeographing, the stop device 114 will be automatically moved rightward far enough to bring the lower step 119 under the arm 53 which will drop downward by gravity to this lower position, carrying with it the ribbon vibrator and ribbon. The consequence is that when mimeographing, the printing portion of the ribbon is slightly lower than it is ordinarily the result being that sufficient clearance is insured for the types when they are thrown to the printing point and they are thus prevented from accidentally catching on the upper edge of the ribbon during mimeographing or stencil writing operations. The edge 122 lioining the lower step 119 with the arm 117 is inclined downward toward the left so that in moving the stop device toward the left and resetting the sub-lever in l a ribbon vibrator, an operatinglever, devices for actuating the operating lever comprising a second or sub-lever, and means :tor eil'ecting a relative shift between the two levers in order to vary the throw of the operating lever, such relative shift being brought about in the present instance by shifting the sub-lever laterally or `transversely of the operating lever 'through means extending to the Afront ofthe machine and terminating in a nger piece or button, as 98; that said sub-lever is upright and is slidable laterally and settable in predetermined positions to vary its effect on the operating lever and is also settable in a position where it is ineective on the operating lever; that the ribbon vibrator' brator, being substantially halt' that of the.

vibrator; that the sub-lever is an actuating device which is intermediatetlie shiftable ribbon vibrator and a non-shiftable keyoperated actuating device, viz., the finger 73; that the sub-lever is pivoted on a bracket which has a pin and slot connection with each of two links at points about midway of the lengths of the links, this construction affording a shifting up and down movement of the sub-lever simultaneously with the links and vibrator' and also permitvting a lateral sliding movement of the sublever and its bracketi independently both of the links and the shiftable platen; and

vthat ribbon stop devices are provided including variable stops to limit variable movement of the ribbon toward the printing point as well as to vary its point of arrest during movement in the opposite div rection.
