Specification of Letters Patent. Application filed July 9, 1904. Serial No. 215.846.

Patented Oct. 16, 1906.

To It whom it may concern:

Be itknown'that I, OSCAR WOODWARD, a citizen of the UnitedStates, and a resident of the borough of Manhattan, city of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements in Type-VVriting Machines, of which the following is a specification.

This invention relates to type-writing machines, and more particularly to the ribbon mechanism thereof.

One object of the invention is to provide an efficient lever-actuated means operable from the front of the machine, whereby any of a plurality of inking-surfaces having different colors or characteristics may'be readily brought to the operative position-,where it will coo erate with the types.

Anot er object of the invention is to provide means for indicating which one of the plurality of inking-surfaces is in operative position.

To the'above and other'ends, which will subsequently ap ear, the invention consists of the features 0 construction, arrangements of parts, and combinations of devices to be hereinafter more fully described, and articularly pointed out in the concluding c aims.

In the drawings illustrating these improve ments, Figure 1 represents the upper part of the left-hand end of a type-writ1ng machine, part of the frame being broken away to more clearly disclose my invention. Fig. 2 is a detail perspective view of the ribbon-spools and the guide or carrier. Fig. 3 is a top plan view of certain of the parts illustrated in Fig. 1

and showing the mechanism arranged for automatically producing the lateral feed within one color or section 0 the ribbon. Fig. 4 IS a similar view of the same with most of themcchanism omitted and showing the ribbon shifted for the use of the other color and the shifting-frame held by the locking-spring. Fig.5 is a side elevation, partly in section, of

the shift-lever and its sleeve-bearing and theforward supporting-arm. Fig. 6 is a top plan .view of a modification of the invention. Fig.

7 is a side elevation of the modification shown in Fig. 6.

The invention is shown applied to a No. 6v Remington ,machine; but it is to be underwheel 8, leaves it at rest. 8 carries on its hub a beveled gear9 and a.

stood that it may be adapted to other forms of writing-machines.

- Considering first Figs. 1 to 4, inclusive, 1

designates a carriage in which is mounted a platen 2, the carriage being arranged to travel above the top plate 3 from side to side of the 1 machine and being propelled'by a spring within the carriage driving drum 4 through the agency ofa strap or band 5. The drum 4 revolves freely on a supporting-shaft 6 and is provided onits front side with a pawl 7,

which engages the teeth of a ratchet wheel 8,

also loosely mounted on the shaft/6. With the feedin movement of the carria e 1 from right-to left the revolving drum am? its pawl 7 turn the ratchet-wheel 8 but when the car riage is returned to its starting-point the drum revolves in the opposite direction, and the pawl 7, failing to act upon the ratchet- The ratchet-wheel s ider 10, the gear 9 engaging a similar beve ed gear 11, mounted on the shaft 12.. The shaft 12 is employed in this class of type-writing machines as the means by which the ribbon-spools are alternatelywound to chan e the direction of longitudinal feed of the ribbon, and it is-not deemed necessary to more fully illustrate this feature of the construction, since it-is well know As best appears in Fig. 3, the beveled gearwheel 11 is formed integral with a sleeve 13,

which is perforated to receive a second sleeve 14, the-two sleeves being secured together by a set-screw. 15. The sleeve 13 is loosely mounted on the shaft 12 and is formed with a crank-arm 16, from which extends a pin 17,

parallel with the shaft 12. A crank-arm 18 is secured fixedly to the shaft 12 and is provided near its end with a slot or opening through which the pin 17 loosely passes,

This construction permits ofthe longitudinal movement of the shaft 12 independently of the sleeves 13 and 14, the beveled. gear 11, and the crank-arm 16, which are held against participation in saidmovement bybrackets 19 1'9, dependin from the top 'plate and through one ,of w ich the sleeve-14 extends.

The crank-arms 16 and 18, through the me-' dium of the in 17, rotate together, so that a rotation of t e gear 11 may be transmitted to position of the-latter.

The shaft 12, which extends from side to side of the machine, has. a beveled gear-wheel secured near its left-hand. end, which gear meshes .with a similar gear-wheel'21 on 'a shaft 22. T he latter shaft carries the ribbonspool 23 and is in turn sup orted in lugs 24, depending from the top p ate. It is to be understood that another and similar gear (not shown) is mounted near the opposite end of the shaft 12 for cooperation with the gear of the other ribbon-spool shaft 25, Fig. 2'.

The spider 10 is provided with several lugs 26.26, which project outwardly, and as the ratchet-wheel 8 and the spider 10 revolve they strike the outer end of a lever 27, pivoted on the shaft 28 of the ratchet wheel 28*, said shaft being supported in a bracket 29, depending from the under side of the top plate 3. The lever 27 carries a pawl 30, which engages with the teeth of the ratchetwheel 28, andas the lugs 26 26 strike the outer end of the lever they cause it to rise and fall, the pawl 30 playing in the teeth on said ratchet-wheel, and thereby causing it to slowly revolve and turn its shaft 28 and a worm 32 thereon. The worm 32 engages the worm-wheel 33 on a vertical shaft 34, mounted. in the bracket 29, and the shaft 34 bears at its upper end a cam 35, the latter having two steps 36 36 and aspiral face 37. The cam 35, though differing in detail from that shown inthe patent to Diss, No. 599,417, generally resembles the latter and its function is similar. It is therefore not deemed necessary to describe the cam and its operation at greater length.

The left-hand ribbon-spool 23 and the right-hand ribbon-spool 3S slide freely on the shafts 22 and 25; but each spool is caused to revolve with its shaft by means of a spline on the sl'iaft or by any wcll-knmvn or desired means. The ribbon 39 passes from the lefthand spool up and over a guide pin 40 and then over the type-basket to the right-hand 1ibbonspool. The guide-pin 40, Fig. 2, has its hearings in two cars 41- of a frame 42, and the latter has depending from its under side two fingers 43, which span the associated spool and controlits movement along the shaft 22. The frame 42 is carried by two supporting-arms 44 and '45, which are provided with sleeves 46 and 47, saidslceves being perforated to receive the pivot-posts 48' and 49, secured to the under side of the top plate. This method of mounting the supporting-arms affords an easy swinging movement, while the swinging ends of said arms are pivoted to different sides of the shifting frame 42 and cause it to move fore and aft of the machine during the swinging movement of the arms. This movement is imparted to the arms bymeans of the short arm 50, 'projec'ting rearwardly fromthe arm 44 near its 'pivot and having a forked end which carries a roller 51, designed to ride ordinarily over the face of the cam 35.

Integral with the sleeve 47, which carries the supporting-arm and projecting forwardly at about right angles to the said supporting-arms, is a shifting or switching lever 52, which terminates ina thumb piece 53,

the latter being close to the under side and front edge of the top plate 3. Seated in a depression or cup 54 just ,to the rear of the thumb-piece is a disk 55 for indicating the color or characteristics of the ribbon-field at the printing-point. A spring 56 is wound about the pivot-post 49 above the sleeve of the supporting-arm 45, and one of its 'ends bears against the, said arm, while the other end bears against the depending rim of the top plate. The spring 56, bearing against the arm 45, tends to force it "and the shifting frame 42, with its supporting-arm, rearwardly and to cause the roller 51 to ride on the face of the'cam 35.

The, forward end of the guide-pin 40 is threaded to receive the sleeve or nut 57, which is formedwith an. annular groove 58 for the reception of-the wedge-shaped end 59 of a flat spring 60, secured to the top plate-by. screws 61.

The shifting-frame 42 supports a ribbon guide plate 62 of the usual or any suitable construction, the other end of the said guideplate being provided with depending arms 63. which control the fore-and-aft movement of the right-hand ribbon-spool 38.

, The inking surface or ribbon 39 is provided with two fields 64 and 65. These fields may be inking-surfaces of two different'colors such, for instance, as black and redor they may have'different characteristics. Thus the field 64 may be copyingribbon, whereas 'the field or section 65 may be record-ribbon, though for convenience the sections will be referred to as of two different colorsblack and red. The black field 64, as here shown, has about twice the width of the red field 65. In Figs. 1 and 3 the ribbon is shown positioned so that the types 66 act on the black field or section of the ribbon, while in Fig.4 the red section is shown in operative position.

The operation of the mechanism will now be described. The revolution of the ratchet- Wheel 8 in the letter-space movement of the carriage from right to left causes the lugs 26 of the spider 10 to strike the free end of the lever 27, and the movement of the pawl 30 on the other end of the said lever, acting on the ratchet 28, causes the latter to revolve and with it the worm 32; The worm-Wheel 33 is turned by the rotation of the worm'32 and carries with it the-cam 35, the face of which 1 IOC IIC

spool.

erallyand shifting the spool 23 fore and aft of themachine alongthe revolving shaft 22. The frame 42, through the ribbon-guide plate 62 and the depending arms or fingers 63, carried thereby, shifts the right-hand ribbonspool 38 in unison with the left-hand ribbon- The action of the ca1n'35 shifts the black section of the ribbon laterally over the printing-center during the longitudinal feed of the ribbon and utilizes every portion of it in amanner well understood. The'relations of the parts during this operation are best seen in Fig. 3, inwhich figure, it will be noted, the

. shifting-lever 52, the thumb-piece 53, and the indicator 55 arecovered by the top plate of the machine. It is obvious, therefore, that Lwhen the indicator is covered the forward or black section of the ribbon is in thepath of the types. The camis of such dimensions that the fore-and-aft movement of the ribbon while the cam coacts with the roller 51 does not carry the front and rear edges of the black section or strip 64 outside the path of the types. I 7

When it is desired to write upon the rear field or red section 65 of the ribbon, the

- thumb-piece 53 is pushed to the left of the operator until the wedge-shaped end 59 of the Hat spring 60 engages the annular groove 58 in the nut 57. The parts will then be in the position illustrated in Fig. 4. The disk 55 will be exposed to the view of the operator, thus indicating that the section of the ribbon to which it corresponds is in the printing-field. The roller 51 no longer rides on the face of the cam 35and the shifting action of the ribbon fore and aft of the machine is dispensed with when the red section is in printing position. The operation of the cam-driving mechanism continues, but the roller 51 having been moved out of the path of the travel of the cam the ribbon-carrier is notafl'ected by it. When it is desired to again write on the black field, the thumb-piece 53 is pushed to the right, freeing the ribbon-frame from the locking-spring and again covering the in dieatingdisk.

In the modified. form of the device shown in Figs. 5 and 7 the shifting-lever 67, theindicator 68, and the thumb piece 69, instead of being formed integral with the arm 45 and sleeve 47, are shown as a separate piece.

This piece terminates at the rear in a split collar 70, which is adjustable by means of a screw 71, which passes through cars 72, with which the collar is provided. By this means the piece maybe attached to the sleeve 49, as it is ordinarily found in the machine,.without altering the construction of the latter in any respect, the split collar '70 surrounding or embracing the sleeve 47. During the operation of these devices it will be observed thatthe longitudinal feed of the ribbon in either direction is in no way interfered with,

touching the ribbon and from a convenient place at the front of the machine. When the ribbon is displaced by another style, the disk.

55 may be replaced by one corresponding to the rear section of the new ribbon either in color, by someword or symbol, or the like.

It is to be understood that I do not desire to be limited to the particular construction herein shown, but that various changes may be made without my invention.

By the term multicolored ribbon I mean two or more inking-surfaces having different colors or characteristics. e
