Specification of Letters Patent.

Patented Dec. 5, T915.

Application filed March 25, 1916. Serial No. 86,671.

To all whom it may concern: I

Be it known that I, CHARLES E. ARCH- BALD, a citizen of the Dominion of Canada,

'and residing at New Brunswick, in the county of Middlesex and State of New filersey, have invented certain new and useful Improvements in Machines for Inking Ribbons; and Ido hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification and to the reference numerals marked thereon.

invention relates to a machine for inking ribbons andis particularly adapted for impregnating or saturating multi-color ribbons for typewriters.

One of the objects of the invention is to provide means for thoroughly and uniformly applying inking materials of different colors upon opposite sides of a ribbon in such a way that the colors will not run or mix, although they are applied immediately adjacent each other upon the ribbon.

A further object of the invention is to provide means whereby various widths and thicknesses of ribbon material may be successfully run through the machine and impregnated oicoated with a plurality of colors upon adjacent surfaces of the ribbon fabric.

Another object of the invention is to provide means for preventing the flow of the inking material of one color into that of the other while the ribbon is being saturated.

Togthese and other ends the invention consists in certain improvements and combinations of parts all as willbe hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings, Figure 1' is a top plan.

view of a machine embodying one form of my invention; Fig. 2 is a side elevation of the machine; Fig. 3 is a sectional v1ew taken on line aa of Fig. 2; Fig. 4c is a sectional view taken on line b-b of Fig. 1; Fig. 5 is an enlarged detail sectional view takenlongitudinally of the ribbon supporting shaft shown in Fig. 3; Fig. 6 is a sectional view taken on line cc of Fig. 1; Fig. 7 is an elevational view illustrating the support for the supply roll of ribbon and the adjustable means connected therewith for taking care of ribbons of different widths adapted to be run through the machine; Fig. 8 is a sectional elevation taken on line d-d of Fig. 1, and Fig. 9 is an enlarged detail sectional view through one of the adjusting screws shown in Fig. 8. for regulating the height of the partition dividing the lower roller into separate inking mediums.

Similar reference numerals throughout the several views indicate the same parts.

Referring more particularly to the drawings, 1 represents the base or bed of the machine which is supported by standards 2. Mounted upon the bed 1 at each side thereof are frames 3 slotted at 4 to receive the upper and lower roller supporting bearings 5 and 6 respectively as clearly shown in Fig. 4. J ournaled in the bearings 5 are the reduced ends 7 and 8 of the shaft 9 which carries the top roller 10. The bearings 5 are held against upward displacement by means of cross bars 11 secured by bolts 12 and adapted to close the upper ends of the slotted frames 3 as shown in Fig. 8. In the bearings 6 are journaled the reduced ends 13 and 14: of the shaft 15 which carries the lower roller 16 which comprises the spaced sections 17 and 18, the latter being shown preferably integral with the shaft 15 while the former is adapted to be positioned thereupon and held against turning by a key 19. Screwed upon the threaded portion 19 of the shaft is a locking nut'2O for holding the section 17 against longitudinal movement. The roller sections 17 and 18 are provided with annular grooves 21 and 22 respectively on their inner faces which are adapted to receive the rings or washers of felt or other yieldable material 23 as shown in Fig. 4:. Between the sections 17 and 18 of the lower roller and the felt washers 23 is placed a partition 24, the purpose of which will be hereinafter explained.

Mounted upon one corner of the bed of the machine is an upri ht support 25 secured to "the bed by suita le bolts 26. Upon the frame 3nearest to the support 25 is bolted or otherwise secured an arm 260 in which is 'journaled at 27 one end of a shaft 28, the opposite end of which is journaled in the top of the support 25. Secured upon the shaft 28 is a gear 29 adapted to'mesh with a gear 30 on the end 7 of the shaft 9 which carries the upper roller 10 and also a fly wheel 31. The gear 30 also meshes with a gear 32 on the end 13 of the shaft 15 which carries the lower roller 16. The shaft 28 is provided with an'idler 33 and a pulley are 34 adapted to be driven by a; belt, (not shown) for operating the gear 29 to actuate the gears 30 and 32 for driving the rollers: 10 and 16 respectively. A belt shifter 34 is slidably mounted in a bearing 35 on the arm 26 for shifting the belt upon the pulley and the idler. On the outer end of the arm 26 isa bearing 36 in which is journaled a shaft 37 carrying a pulley 38 upon which a belt 39 is mounted, the belt being driven preferably by a pulley 40 mounted upon the shaft 28. The shaft 37 carries a spool 41 upon which the ribbon 42 is adapted to be wound as it is fed between the rollers 10 and 16 from the supply roll 43, which is rotatably mounted upon a removable pin 44 carried by the upright supports 45 slidably mounted on a shaft 46 supported by suitable brackets 47 seated on the bed or base 1. In order that supply rolls of different widths may be used to carry various widths of ribbon material the supports 45 are slidably mounted upon the shaft 46, the lower ends 48 and 49 of the supports each having threaded engagement with oppositely threaded portions 50 and 51 respectively of,

a shaft 52 rotatably mounted upon the brackets 47, one end in a bearing 53 and the other in a sleeve 54 slidably mounted in a bearing on the opposite bracket 47 as shown in Fig. 7. A hand wheel 55 is provided for rotating the shaft 52 to cause the oppositely threaded portions 50 and 51 of the shaft to move the supports 45 either toward or away from eachother as may be desired according to the width of the supply roll 43. As the ribbon 42 is adapted upon leaving the roll 43 to pass behind and engage the rotatably mounted shaft 46, guides for the ribbon at this point, are provided in the form of circular projections 56 extending inwardly of the supports 45 as shown in Fig.

7. The end of the shaft 52 opposite the hand wheel 55 is rotatably mounted in the sleeve 54 and extends therefrom into rota table engagement with an arm 57 and is provided with a groove 58 into which projects one end of a screw 59 seated in the arm 57 whereby the arm 57 is secured in rotatable engagement with the shaft 52. The lower end of the arm 57 carries a hand wheel 60 having an extension 61 in threaded engagement with one of the brackets 47, a collar 62 being mounted upon the extension to maintain the latter in proper position upon the arm. By turning the hand wheel 60 the shaft 52 and the supports 45 thereon may be moved bodilv in either direction to prop erly aline or adjust the ribbon carrying supply roll 43 with respect to the partition 24 mounted between the sections 17 and 18 ofthe roller 16. A somewhat similar ribbon adjusting means is mounted immediately in front of the rollers 10 and 16 which comand adjustably prises a pair of arms 63 extending forwardly from and secured upon the upper ends of the frames 3, as shown in Fig. 1. The arms 63 are adapted to rotatably support a shaft 64 one end of which is threaded to receive a thumb nut 65 rotatably mounted and secured in theforward end of one of the arms 63 and adapted to be turned to move the shaft 64 transversely of the machine to properly aline or adjust the ribbon 42 with respect to the partition 24 and 'the rollers 10 and 16. The shaft at the end opposite to that which receives the thumb nut 65 is reduced as shown at 66 in Fig. 5 and is provided at this point with a sleeve 67 tightlydriven upon the reduced portion and adapted to slide therewith in the arm 63 opposite the thumb nut 65 when the shaft 64 is moved in opposite directions by the thumb nut. The sleeve 67 is split or slotted at 68 and a stud 69 carried by the arm 63 engages the sleeve within the slotted portion 68" to prevent the turning of the shaft 64.

In order to provide means for receiving and guiding ribbons of various widths upon the shaft 64, I provide right and left hand carried by the frames 3. By turning the thumb nuts 70 the guides 73 may either be moved toward or away from each other to accommodate ribbons of different widths, the guides being free to slide upon the roller 74. The spool 41 on the shaft 37 is slidably mounted thereon and may be moved to line up with the guides 73 and supply roll 43 when they have been properly adjusted with respect to the partition 24 and rollers 10 and 16; In placing the ribbon in position upon the machine to be saturated or impregnated with the inking or other material the ribbon supply roll 43 is positioned between the supports 45 upon the pin 44, the free end of the ribbon being carried over the shaft 64 between the guides 73 and over the roller 74 down in front of and between the rollers 10 and 16 and thence to the spool 41 to which it is secured and upon which it is wound when the machine is set in operation by shifting the belt from the idler to the driving pulley 34. Beneath the roller 16 is movably mounted a divided pan or tray 75 adapted in the present instance to hold inking materials of two colors. the tray being divided by the adjustable partition 24. upon opposite sides of which the roller sections 17 and 18 revolve with their lower edges projecting into the inking material plates 78 and prevent the transverse displacement of the pan. The side plates 78 are provided with upwardly extending front and back arms 81 and 82 respectively, which are adapted to support cross bars 83 and 84, which have their ends secured to the arms 81 and 82 preferably by means of the screws 85. The pan is provided longitudinally thereof with. a grooved bar 86 extending along the bottom and up the end walls of the pan as shown in Figs. 4: and 8. The grooved bar 86 may be either cast integral with or otherwise secured in the pan. The partition 24 is adapted to fit snugly in the groove of the bar to prevent the mixing of the inking material in the opposite sides of the pan. The partition 24 is made adjustable up and down in the groove by means of screws 87 secured to the partition at 88 and extending through thumb nuts 89 having reduced portions 90 extending through and rotatably mounted in the cross bars 83 and 84 as shown in Figs. 8 and 9. The thumb nuts are held against displacement by means of nuts 91 which are riveted upon the extension 90 at the bottom side of the cross bars 83 and 84. The partition 24 is thus made adjustable vertically with respect to the roller 10 and pan 75 sothat the distance between the top of the partition and the underside of the roller 10 may be delicately adjusted to suit the different thicknesses of ribbon material that may be run through the machine and at the same time exert suliicient pressure upon the ribbon on both sides of the axis of the rolls to prevent the flow of the ink from one side of the ribbon to the other as the sections of the lower roller carry the ink to the ribbon. The partition 24 is carried upwardly a considerable distance in front of the roller 10 as indicated at 92 and also slightly above the bottom of said roller in rear thereof as indicated at 93 in Fig. 8. This is done to overcome any tendency of the ink to flow or spread across from one of the bottom roller sections to the other at this point, as might be caused by capillary attraction or otherwise. The front ortion 92 of the partition is carried up higher on the roller 10 than the rear portion 93 and is intended also to prevent anv splashingof the liquid across fr m one of the lower roller sections to the other which might be caused by the tendency of the revolving roller to throw the ink upwardly on this side of the machine. The portion 93 is carried up in contact with the ribbon approximately to the point where the ribbon begins to leave the lower surface of the roller 10 which is high enough to prevent any of the ink upon opposite sides of the partition from spreading or flowing across from one of the roller sec'tionsto the other at this point. The partition 24 is of very narrow width and is preferably adjusted vertically with respect to the top of the lower roller sections to such a degree as to extend thereabove a very limited amount whereby a slightly greater pressure is exerted upon the ribbon between the partition and the upper roller than between the upper and inking roller. The result is that the ribbon upon leaving the rollers is thoroughly and uniformly saturated or impregnated with the two colors upon opposite sides of its center, the inking material being prevented by the partition from mixing upon the ribbon? By reason of the adjustability of the roller section 17 the colors may be applied so close together that no uninked space will be visible between them, or if desired, said roller sections may be adjusted to space the colors apart sufiiciently to produce a visible uninked space between them,

The bearings 5 of the upper roller 10 are preferably secured at the top of the frame members 3 by screws 94 extending through the cross bars 11 into the bearings. The lower bearings 6 upon which the pan or tray 75 is suspended are movable up and down in the slottedframes and are supported by rods 95 slidably mounted in the frames as shown in Fig. 4C. The rods are threaded on their lower ends at 96 to extend through the short arm 97 of a lever pivoted at 98 to a bracket 99 secured to the bottom of the base or bed 1. The other arm 100 of the lever is provided with an extension 101 having a series of notches 102 which are adapted to receive the looped end 'of a rod 103 carrying a weight 10-1- which serves to force the lower roller 16 in position to compress and hold the ribbon 42 in contact with the upperroller 10. The weight 104 may be adjusted upon the lever arm 101 to secure any pressure between the upper and lower rollers which may be found desirable, the shaft 15 at the same time being supported in parallelism to the shaft 9. The rod 95.may also be adjusted upon the lever arm 97 by loosening the jam nut 105 and turning the handle 106 on the bottom of the rod. I

Pivotally mounted upon clamping screws 107 on the cross bar 84' are plates 108 which carry at their forward ends vertically disposed scrapers or guards 109 adapted to be positioned upon the end faces of the upper its pivot by means of a set screw 113 as shown in Fig. 2.

While I have shown one embodiment of my invention I do not wish to be limited to the detail construction of this mechanism as the same may be readily modified without departing from the spirit of my invention,

1 nor do I'wish to limit myself to the use .of

the machine for applying compounds of only two colors to fabric material or to the use of inking typewriter ribbons, as it will be understood that the machine is adaptable for use in connection with other classes of work.
