TYPE-WRITER SPECIFICATION forming part of Letters Patent No. 631,144, dated August 15, 1899.

Application filed September 22, 1898. Serial No. 691,609. (No model.)

To all whom t may concern:

Be it known that I, GEORGE S. ANDERSON, a resident of the city of New York, borough of Brooklyn, in the county of Kings and State ofA New York, have invented certain new and usethe entire width of the ribbon forprinting.

The mechanism is such that a single ribbon can be used, or, if desirable, different ribbons can be used side by side to be alternately utilized in different parts of the work. For instance, if it is desirable to print part of the writing in one color and part in another my mechanism is adapted to accomplish this result. I have also provided an independent ribbon mechanism for multiple-copy work.

I have shown my invention applied to a machine adapted for writing in bound books; but it can be readily applied to other typewriting machines.

The general style of machine which I show is the Elliott it Hatch book type-writer; but my ribbon mechanism is diiferent inl many `particulars from that now used on that ma.

chine.

Figure 1 is a plan View of the machine, showing my mechanism for shifting the sin glo-copy ribbon mechanism. Fig. 2 is a side view of thatpart of Fig. l which comprises my multiple-copy ribbon mechanism. Fig. 3 is a side View in section on line X X of Fig. 1. Fig. 4 is an enlarged sectional View in perspective of the parts of the carriage of Fig. 1 which show my ribbon-shifting mechanism. Fig. 5 is a detail modification of the ribbon mechanism of Fig. 4, showing a single ribbon instead of the two ribbons of Fig. 4. Figs. 6, 7, 8, and 9 show a modified form of my invention. Fig. 6 is a plan view of the carriage and of the running-gear which supports the carriage. Fig. 7 is a sectional view on the line Y Y of Fig. 6. Fig. 8 is a perspective view of the carriage and ribbon mechanism Fig. 9 is a View of the ribbonof Fig. 6.

holder of Fig. 6 seen from beneath. Figs. 10 and 11 show a still different modification of my invention. Fig. 10 is a plan View. Fig. 11 is a side view. In this figure the platen is shown in section.

Referring particularly to Figs. 1 to 4, the two ribbons 1 and 2 are mounted upon the two ribbon-spools 3 in the usual manner. They are separated from each other by the disks 4 4. Both ribbons pass through the ribbon-guide 5 and are separated from each other in the ribbon-guide by the pins 6 6. The ribbon-guide is mounted on the plate 7 and is free to slide thereon. It is connected to the ribbon-shift-key lever 8 by the connecting-wire 9. The ribbon-shift-key lever 8 is provided with key 10 and is pivoted to the carriage by the pin l1 and held normally in a raised position by the spring 12. By pressing the ribbon-shift key the opposite end of the lever 8, which is attached to the connecting-wire 9, is moved to the rear, thereby presenting a new surface of the ribbon at the printing-point. Mounted on the upperbridge 13 of the carriage is the ratchet-bar 14, which is provided with teeth to hold the ribbonshift key in a plurality of raised positions. Normally the ribbon shifting key stands above the top of the ratchet-bar 14. The ratchet-bar is provided with four teeth to hold the ribbon widthwise in any one of the four dierent positions. When the key is in its normal raised position, the surface of the rear ribbon is presented to the printing-point near the back edge of the ribbon. When the shiftkey is fastened in the upper tooth of the ratchet-bar, the front surface of the rear ribbon is presented-to the printing-point. When the shift-key is fastened in the next to the bottom tooth, the surface of the front ribbon is presented to the printing-point near the back edge, and when the key is ,fastened in the IOO Fig. 5 also shows a pointer 15. This pointer extends toward the front of the machine and then is bent around, so as to point toward the rear of the machine directly in front of the printing-point. The ribbon-shifting key 10 can be depressed a distance below` the bottom tooth on the ratchet-bar 14 until it is brought into contact with the bridge 13. In this position the entire ribbon 1G is shifted back of the printing-point, so that the printing-point is exposed t0 View and the pointer 15 is directly in front of the printing-point and indicates the proper position of the letter on the printing-line.

In the modification shown in Figs. 6 to 9, inclusive, the mechanism for shifting the ribbon widthwise also comprises the shift-plate 17, which controls the direction of feed of the ribbon. In this modification the plate 18 is firmly screwed onto the shift-plate 17. The plate 18 is provided with the holding-face 19 and with the holding-face 20. Between these two holding-faces is an inclined or beveled part 21. 'Vhen the ribbon is feeding toward the left side of the carriage in the position shown in Figs. 7, and S, the ribbon-shiftingkey lever S is in engagement with the holding-face 20. W'hen it is desired to feed the ribbon in the opposite direction or from left to right, the shift-plate 17 is moved from its extreme left-hand position to the extreme right-hand position, slots 21 21 being provided in the shift-plate for this purpose. The shiftplate 17 is fastened to the carriage by means of screws 22 22, which are inserted through the slots 21 21, so as to hold the shift-plate in place on the carriage and also permit of its movement sidewise thereon to feed the ribbon both toward the left and right on the carriage. The shift-plate isv provided with suitably-actuated pawls 23 23, which alternately engage with the ribbon-spool ratchets 24 24 to feed the ribbon respectively toward the right and toward the left on the carriage.

As the mechanism for actuating the pawls forms no part of my invention, it need'not be shown or specifically described. As an example of actuating mechanism that can be used I refer to that now in public use upon` the book type-writer hereinbefore referred to. In that machine the movement of the shiftplate to one side engages the corresponding spool-ratchet with the corresponding pawls and causesa corresponding feed of the ribbon.

Then the shift-plate 17 is moved into its extreme right-hand position on the carriage, the holding-face 2O is moved out of engagement with the shifting-key lever S and the holding-face 19 is moved into engagement therewith. The beveled part 21 is provided so as to permit the shifting-key lever 8 to slide up the incline when the shift-plate 17 is returned from its right-hand position to its left-hand position on the carriage.

In the modification of Figs. G to 9 I have shown only a single ribbon; but of course the two ribbons of Figs. 1 to -l can be utilized, if

desired.V The ribbon guide 5 is mounted upon the plate 7 and is connected to the shifting-key lever 8 by the connecting-wire 92. The ribbon-guide is provided with lugs 25 25, which are bent up and folded around plate 7a, and thus connect the ribbon-guide with plate 7 and permit it to slide backward and forward thereon. The ribbon-guide is also provided with lugs 2G 26, which are merely bent upwardly on each side of the shift-plate 7, and in conjunction with lugs 25 25 prevent any lateral movement of the ribbon-guide upon the plate 7a. The ribbonguide is also provided with the pointer 15, which performs the functions of ribbon-guide and pointer of the construction shown in Figs. 1 to 5.

The dotted lines in Fig. S marked A B C D are intended to show the various positions to which the ribbon can be shifted widthwise for printing. The dotted line A shows the printing position of the ribbon when the shifting-lever 8 is in engagement with holdingface 20. The dotted line B shows the portion which will be moved to the printing-point when the direction of the feed of the ribbon is reversed and the shifting-key lever S is in engagement with the holding-face 19. In order to bring the printing-surfaces C and D to the printing-center, the ribbon-spools must be shifted on the machine, spool 27, Fig. G, being placed on the opposite side of the carriage on shaft 29 and spool 28 being placed on shaft 30. In any of these printing positions of the ribbon the depression of the shifting-key 10fl moves the ribbon entirely back of the printing-center, so as to expose the writing to view, and moves the pointer 15a rearwardly until it is just in front of the line of print. In this modification the ribbon is inserted in the guide from beneath, while in the construction of Figs. 1 to 5 the ribbon is inserted in the guide from above, slots being provided in the guide for the insertion of the ribbon. The insertion of the ribbon from above or from beneath is a mere question of convenience.

Figs. 10 and 11 showa still different modification. In this modification instead of having a plate with two holding-faces attached to the shift-plate, as in the modification of Figs. 6 to 9, there is a plate 1S, mounted on the carriage and pivotally connected therewith by screw 31. Mounted on the shift-plate 17n is a screw 32. The plate 18L is provided with a slot, through which screw 32 passes. Then the shift-plate 17 is moved sidewise on the carriage from the position shown in full lines to the position shown in dotted lines, the plate 18 is thereby forced to revolve above its pivotal screw 3l, so that its holding-face 20 is moved out of engagement with the shiftkey lever Si. The spring 12 then forces the shift-key lever 8b forwardly until it is brought into engagement with the fixed holding-face 19, which is fixedly mounted on the carriage. This last position of the xed key-lever is IOO IIO

, ing machines; but in such prior construction only one of the copies has been written from the ribbon and the remaining copies have been written from carbon-paper. The advantage which I secure by writing each of my copies from a ribbon is that I am thereby enabled to secure a number of copies of identical quality, ctc. For instance, I may use indelible ribbons for each copy, thereby securing a number of indelible copies.

In my construction I have shown mechanism for making two copies simultaneously; but the multiple-copy ribbon mechanism may obviously be arranged for printing an indenite number of copies .at the same tima-as, for example, by winding a number of ribbons on the multiple-copy ribbon mechanism and by inserting the sheet of paper for one copy under each of said multiple-copy ribbons.

Referring to Figs. l to 3, mounted independently at the rear of the main frame 40 are the lugs 4l 4l and at the front of the frame the lugs 42 42. There are two lugs 4l 4l-one at each side of the rear of the frame 40-and there are two lugs 42 42-one at each side of the front of the frame. The shaft 43 Vis mounted in the lugs 4l 4l andthe shaft 44 is mounted in the lugs 42 42. The shafts are free to revolve in their bearings in the lugs.

Shaft 43 is provided with the knurled wheel 45 on the right-hand side of the machine for revolving the shaft by hand, and shaft 44 is provided with hand-wheel 4G for the same purpose. By revolving the hand-wheel 45 in a right-hand direction, or in that in which a screw is driven into a piece of wood, the

multiple-copy ribbon 47 can be wound upon.

shaft 43. By revolving the hand-wheel 46 in a left-hand direction, or in the direction in which a screw is unscrewed from a piece of wood, the ribbon 47 is wound upon shaft 44. In this manner the ribbon may be shifted slightly forward and backward upon frame 40, so as to present different portions of the surface of the ribbon to the line of print. If the ribbon 47 were not thus moved forward and backward on the frame, the printing would always occur in lines across the ribbon, and so the ribbon would be worn out where the lines of print happened to come, while the remainder of the ribbon would not be used at all.

frame 40 this difficulty is obviated. I have also provided mechanism for alternately wind- By providing means for shifting the. ribbon slightly forward and backward on ing ribbon 47 on shafts 43 and 44 automatically. On the left-hand end of each of the shafts 43 and 44 are rigidly fastened the crankarms 4S and 49, respectively. The upper ends of these crank-arms are connected together by crank-shaft 50, so that when either one of the shafts 43 44 is revolved the shaft 50 will be moved simultaneously therewith. Depending from the frame 40 is the lug 5l, which is mounted on the left-hand side of the frame, about half-way between the front and the back of the machine. Pivotally connected with lug 51 is the ratchet-wheel 52. Pivoted to ratchet-wheel 52 is the cran k-shaft 53,which at its opposite end is connected to crank-shaft 50. Vhen the ratchet-wheel 52 is revolved continuously in one direction, the crank-shaft 53 moves crank-shaft 50 alternately forward and backward through twice the length of the radius from the pivot-center of ratchetwheel 52 to the center of connection of crankshaft 53 with the ratchet-wheel. Therefore the continual revolution of ratchet-wheel 52 in one direction moves the ribbon 47 Iirst backward step by step on frame 40 and then forward step by step on frame 40 alternately. Ratchet-wheel 52 is forced to move step by step in one direction every time the carriageframe 54 is moved toward the rear of frame 40. This is eected by means of pawl 55, which is hinged to the left-hand side of the carriage-frame 54. When the carriage-frame is spaced forward line by line on frame 40, the pawl 55 trips freely over ratchet-wheel 52; but when the carriage-frame is pushed backward on frame 40 for the purpose of writing a new sheet or page the pawl 55 engages with the teeth of ratchet-wheel '52 and partially rotates that ratchet-wheel, thereby imparting a stepby-step movement to the ratchet always in the same direction. The pawl 55 may be prevented f rom tripping out of the ratchet-wheel 52 when the carriage-frame is moved back- .ward by anysuitable means. I have provided pin 56, mounted on the carriage-frame, for this purpose; but any other suitable means may be employed therefor.

Having thus described my invention and without limiting myself to the precise details sh'own, what I claim, and desire to secure by Letters Patent, isi 1.
