TYIPE-NRITING MACHINE.

Application filed August 21,

To all whom it may concern:

Be it known that I, JOHN H. BARR, citizen of the United States and resident of Syracuse, in the county of Unondaga and State of New York, have invented certain new and useful. improvements in Typell riting Machines, of which the following is a specification.

lily invention relates more particularly to the ribbon mechanism of typewriting niachines and has for its main object the pro vision of improved means for controlling the vibratory movements of the ribbon under the operation of the printing keys in order to vary the widthwise portion of the ribbon presented to the types.

A further object of my invention to provide ribbon controlling means of the character specified which is particularly applicable to typewriting machines in which a shifting platen is en'iployed, the ribbon controlling means operating in either position to which the platen may be shifted.

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.

iify invention shown herein as applied to a machine essentially resembling the No. 10 Remington typewritingmachine but the nature of the invention is such thatit may be readily adapted to other styles of writing machines.

In the accompanying drawings, Figure 1 is a rear elevation partly in section of a Remington No. 10 typewriting machine embodying my invention parts of the machine being omitted and parts broken away. Fig. 2 is a vertical front-to-rear central sectional view of said machine. Fig. 3 is a fragmentary side elevation with parss in section illustrating some of the'parts shown in Fig. 2 as they appear when the platen is shifted. Figs. 4 and are fragmentary operating views as seen from the left-hand side of the machine. Fig. 4 showing the parts in operative position when set for presenting the upper field of the ribbon to the types; and Fig. 5 showing the corresponding operative posi Specification of Letters Patent.

1911. Serial No. 845,210.

As appears from Figs. 1 and Z, the main frame of the machine comprises a base 1, corner posts 2 andwa top plate 3 which supports stationary rails t on which runs a can riage truck A. platen 6 is mounted in a platen frame 7 which is supported on said truck by links 8 so that said platen frame can be shifted up and down to change case. Said platen frame comprises a cross bar 10 on which is journaled a roller 11 that is adapted to run on a shift rail 12 supported by upright arms 13 rising from a transverse bar 14 which is supported by upright rods 15, each rod being pivoted at its lower end at 16 to a shift key lever 17 which is operated by a shift key 18. The platen normally stands in its lower case position as shown in Fig-.- 1 but may be shifted upward by depressing either of the shift keys 18.

Fig. 3 shows the platen in shifted position. The rail 12, cross bar 14 and uprights 13 and constitute a shiftable "frame for controlling the shifting movements of the platen. Printing key levers 19 are provided with keys 20 and are connected by links 2.1 with sub-levers 22, said sub-levers-in turn being connected by links 23 with front-strike type bars 24 mounted on hangers 25 secured to a stationary segmental support 26. A universal bar 27 underlies the key levers and is supported on arms 28. depending from crank arms 29 which project rearward from a transverse rock shaft 3O pivoted at its ends in the sides of the base. Projecting from said rock shaft near its middle is an arm 31 which is connected by a link 32 with certain of the escapement devices (not shown). Ribbon spools 33. are supported one at each side of the machine below the top plate on shafts 34, and a ribbon 35 is wound on said spools and led upward therefrom through openings in the top plate, thence over stationary guides 36 and through slots formed in the head of a ribbon vibrator 37 arranged about centrally between said stationary guides. The means for turning the spools in alternation to feedthe ribbon longitudinally are not herein disclosed but are preferably of the ordinary constriiction found in the Remington machine.

tion of the parts when set for the lower rib.- As clearly appears from Figs. 2 and 6, hon field. Fig. 6 is a perspective view of the the vibrator is elf-set rearwardly below its ribbon vibrating andcontrolling mechanism. head and is provided with 3. depending stemlike portion 38 which is guided in slots in a bracket 39 secured to the rear of the type bar segment 26, the construction permitting free up and down vibratory movements of the vibrator 37. Secured to the stem 38 is a rearwardly projecting stud 40 through which the vibrator is connected with novel vibrating devices and means for regulating the same now to be described. The'stud 40 is formed with a groove which is engaged by the forked end of a laterally extending horizontal lever 41 fulcrumed at 42 on a bracket 43 secured to the cross bar 14. The opposite arm of the lever 41 is connected by a vertically disposed link 44 with the horizontal arm of an operating member of bell crank 45 fulcrumed at 46 to a bracket 47 secured by screws 47 to the transverse bar 14, said bracket shifting withsaid bar when the platen shifting frame is actuated. The downwardly extending arm of the bell crank is formed with oppositely disposed arcuate slots 48 and 49, the slot 48 opening rearward and being nearer the axis of motion or fulcrum 46 than is the slot 49, which latter slot is closed at its rear end and open at its forward end. The slot 48 is engaged by a lateral stud or headed pin 50 fixed to the rear end of a link or actuator 51 pivotally connected at its forward end 52 to an upright arm 53 secured to the rock shaft 30. Similarly the lower slot 49 is engaged by a headed pin or. stud 54 extending laterally from a link or actuator 55, the forward end whereof is pivotally connected at 56 with the crank arm 53. It will be observed that the connecting point 56 is nearer the axis of gaging in a cam slot formed in an extensionmotion of the rock shaft 30 than is the connecting point 52.

In order to connect the links 51 and 54 alternatively with the bell crank 45 a hand controlled coupling device or connector is provided which in the present instance is in the form of an arm 57 pivoted at 58 to an extension 45 of the bell crank 45. The arm 57 lies close to the left-hand face of the bell crank and extends horizontally rearward from the pivot 58. Said arm is provided with a finger or engaging device 59 which extends downward and is adapted to co operate with the front-of the stud-onengag ing device 54. The rear end of the arm 58 terminates in an upwardly extending finger or engaging device 60 which is adapted to-cooperate with the side of the stud or engaging device 50 when the downward finger 59 is in inoperative position as shown in Figs. 5 and 6. An upwardly extendln-g link 61- connects the coupling devi'ce 57 with the rear arm of a lever 62 fulcrumed at 63 on a boss or projection 64 on the bracket 47. The forward arm of the lever 62 terminates in a rounded finger 65 and said finger en 66 of a slidable bar 67, said cam slot coinslidable stop bar heretofore employed in the Remington machine. The stop bar 67 is formed with uide slots71to cotiperate with screws 72 which screws enter the transverse bar 14 and retain the bar 67 against the rear face of said bar 14; The slide bar 67 is or Figs. 1 and maybe provided with upright stop portions or fingers 73 and 74 and are adapted to cooperate with the stud 40 to limit the vibraf tory movements of the ribbon vibrator.

- The slide bar 67 is provided at its lefthand portion with a vertical slot 75 throu h controlled devices'for moving it back and forth longitudinally. Said devices include.

a stud 76 which projects into the slot 75 which the bar 67 is connected with manual I from the upper end of a crank arm 77 to.

which said stud is secured. The crank arm is fixed to the rear end of a horizontally disposed and forwardly extending roekshafta finger button or key 81 by which the shaftmay be given rotary ments to cause the stud 76 to slide the bar 67 back and forth.

The construction is such that though the key 81 is mounted on the frame of the ma chine and the bar 67 is on the shift frame; ,the pin and slot connection 76 and 75 permits shiftin movements ofthe bar independently of and without obstruction from the key and the parts fixedly related there-v to. A finger or ointer 82 secured to the rear of the finger utton 81 is adapted to cooperate withindicating marks on the front ofthe plate 80 to indicate the position of the controlling mechanism for the ribbon vibrat-.

ing devices. In one of the plurality of positions in which this controlling mechanism may set the ribbon is adapted to vibrate to such an extent as to present only its upper field or half to the types atprinting oporation while when the control mg mechanism is set in another position the vibrating mechanism will give a greater extent-of throw to the vibrator at printin operation and so as to present the lower fie d or .stripe of the ribbon to the types. This will be more clearly understood from the following explanation of the mode of operation of my invention. J

. My improvements are particularlyada'pted for use with a two-color ribbon, and ac-.

cordingly I have illustrated the ribbon 35 as divided ll. gitudinally into two-fields of different characteristics or colors, the-upper orena? field a, for example, bein black and the lower field 6 red. the parts are in the normal relationship shown in Fig. 1, 2 and 6. in these views the platen is shown in lower case position and the coupling device or controller 57 is shown set in its upper position with the finger 60 in. operative engagement with the stud 50 thus rendering the link-or actuator 51 operative on the bell crank 45. The con troller 57 is held up in the position described by the link 61 which in turn is controlled by the lever 62, said lever 62 having its finger 65 engaged with the dwell '69 of the cam slot, thus maintaining the forward end of the lever in its lower position and the rear end thereofraised in upper position. If

- now one of the printing keys be depressed it will operate on the universal bar 27 to lower the latter, causing the rock, shaft 30 to turn on its axis and swinging the arm rearward or in the direction of the arrow in Fig. 6. This movement of the arm will push the links 51 and 55 both longitudinally rearward and the motion of the link 51 will be transmitted through the stud 50 to the finger and thence to the bell. crank 45, swinging the downward arm of said bell crank rearward and lowering the horizontal arm thereoflpulling down the link ell and through the lever 41 raising the vibrator 48, the parts being so adjusted that the vibrator will be lifted far enough to present the lower ribbon field b to the types. During this movement the stud 54 will play idly in the slot l l hen the vibrator has reached the printing position above described the bell crank and associate parts will be in the position illustrated in Fig. it will be understood that during the movement from the Fig. 1 to the 5 position the link 61 willswing about its pivotal point of corn nec'tion with the lever 62 a center but this so nearly coincides with the pivotal axis of the bell crank lever that the relationship of the link 61 and arm 5'7 with the bell crank 45 is substantially the same in the normal and operative positions. Upon releasing the printing key the ribbon vibrating mechanism will be restored to normal position by gravity and the usual or other suitable restoring springs.

Assuming that it be desired to write on the upperor black field a of the ribbon the operator turns the button or key 81 so as to cause the stud 76 to act on the slide bar 67 and slide it inward or toward the middle of the machine until arrested by the engage ment of the ends of the slots 71 with the screws 72. If then the key 81 be released the slide bar and the connected parts will be retained set inthe new position by reason of the frictional engagement of the slide bar itself with the rear fate of the transverse bar 14:; During the inward sliding movei: Let it be assumed that ment of the bar'67 the cam or inclined slot 68 will act on the finger to raise the latter and causeit to engage with the dwell 70 which is at a greater elevation than the slot portion 69, the result being that the forward arm or" the lever 62 will be raised and the rear arm depressed, thereby lowering the link 60 and swinging the arm 57 downward ated, causing the arm to swing rearward,-

the movement of said arm will be transmitted to the bell crank 45 through the lower actuator or link The relationship and adjustment of the parts is such that a less extent of movement will be transmitted to the bell crank by the lower link, and the vibrator will in consequence not be lifted or vibrated so high as previously but to a lesser extent and with the result that the upper ribbon field a will be presented to the types. During this movementthe stud 50 will play idly in the slot 48. The operated position of the parts when set in this relationship is illustrated in l ig. 4. lily improvements have the advantage over prior known constructions of simplicity and case and certainty otpperation and are nu'ticularly adapted for use with a machine of'the shitting platen variety since the-relationship of the parts of the ribbon vibratingaud controlling mechanism is not'substantially effected by the shifting of the platen. This latter advantage will be best understood from a comparison of lfigs. .2 and which respectively show the parts in lower and upper case positions. In shifting from lower case to upper case it will be seen that the bracket or support l7 will shift upward with the shifting platen frame and platen and will carry with it the bell crank 45 and the parts supported thereon including the arm 57, link 61 and lever (i2. Since the slide bar 67. lever 4-1 and Vll)1 or 3? also shift with the platen the relationship of the vibrator and the train of devices for actiuib ing and controlling the same down to and including the bell crank 45 and controller 57 will be the same subsequent to the shift as before. The rock shall: 30 and arm 53 of course are not effected by the platen hi t't and the only change in the train of ribbon devices which does take place is that the two links 51 and 55 will swing upward on their respective pivotal connections 52 and 56 from positions a little below the horizontal to corresponding position slightly above the horizontal. I The action of the links on the bell crank 45 will not be substantially e ffected by the shift;

Various changes may be made without departing from the spirit of my invention.
