' have invented'certain new and useful Improvements in Ribbon Attachments for. Sight-Viriting Type-,lYriters, of which the following is a specification.
One feature of ,my present invention relates to means for shifting the ribbon from a position'over the writing-point to a position which will permit the writing to be observed;
' fore been customary in front-strike machines,
.and to this end my invention consists in mounting the ribbon-spools in a front-stril e machine on horizontal axes and feeding the ribbon from one spool to another, with its greater transverse dimension extending horizontally instead of vertically, as has heretothe portion of the ribbon adjacent the printing-point being rotated or shifted from a hor zontal to a vertical position to bring it in front of the type each, time a key is depressed.
Another feature of my present invention relates to means for changi the throw or shift movement of the ribbon in order to present different portions of the ribbon over the striking-point for the purpose of economizing in the use of the ribbon or utilizing different portions of a polychrome ribbon; and to this end no invention further consists in providing shlftable means for rotating or swinging the ribbon in either of two directions, so that either of its two arallel edges may be presented upward when it is brought over the My invention further consists in combining with this shifting means connections through which the shifting or changing of the throw of the ribbon may be accomplished independently and manually, so that when the mechanism is set to throw the ribbon ina given direction this particular throw will continue to be imparted to the ribbon and the writin will be in a straight line on that portion 0 the ribbon presented by the'throw until the mechanism is again set to reverse the throw and cause the writing to take place in a straight line along a differentportion of the ribbon.
The invention further consists in combining with this means for setting the reversing mechanism a connection whereby the change or shift in the direction of oscillation of the ribbon will follow the shifting of the ribbon feed, so that when it is desired to employ the the reversing connections,
ribbon and then in a straight line on the other side of said line. My invention will be fully understood upon reference to the accompanying drawings, in which one embodiment of my invention is illustrated as a plied to a known. form of front-strike mac une. Y
Inthe drawings, Figure 1 is a vertical section of the machine from front to roar. Fig. 2 is a vertical section from side to side in a plane in front of the ribbon-guide. Fig. 3 is a detail horizontal section showing the means for shifting'the Ilbl)01l- 'llld6 through a rc--' versing connection to change the throw of the ribbon-guide. Fig. 4 is a detail side eke 'vation of themeans for turning the ribbon-. guide in one direction. Fig. 5 is a side elevation of the means for tul'nim the rib bonguide in the other direction. Fi 6 is a ver tical section-through the slide which throws the connecting-link into one or the other of Fig. 7 is a top plan view of the ribbon-guide and its connections. Fig. 8is a rear elevation of the means for throwing the ribbon-feed shift into and out of engegementwith the means for inyerting the throw of the ribbon, and Fig. 9 is a sectional view of the sai no.
Referring to Fig. 1, 1. roprrstints the print.
ing-platen, mounted on thepapor-carriago .2, fulcrulned at 3 and adapted to be moved upward or returned to its normal position by v the shifting-frame 4 for upper any lower case .wr1t1ng,- as is well known 111 machines of this class. Mounted upon the shift-frame 4, so
as to move with it and maintain constant rclation thereto is the ribbon-inter osin lover 5, fulcrumed at 6, connectedat 7 with a link 8 and engaged at 9 by a slotted arm .10,
mounted upon the horizontal sliding bar 11, which is actuated each time a key is depressed. 12 represents the ribbon guide,' which rests normally in horizontal position and receives the ribbon 1 3 fromthe spools 14', that turn on horizontal axes. In order that the ribbon may be presented over the print ing-point, the guide 12 is mounted on a leve r 15, consisting of two members fulcrumed at 16 in a supporting-arm 17 on the upper-case shift-frame 4, and lever .15 is swung upon its fulcrum 16 by the link .8 each: time a key is depressed; but the linl f8 is connected with enter a perforation in either of said arms. When engaged with the arm'25, the circularack sw1n s'until its shoulder 20 meets the 3 guide on its pivot 19 until its shoulder 20 strikes a pin 21, when the ribbon-guide, with the ribbon, will be in the position shown in dotted lines in Fig. 5, and further upward movement of link 8 will then throw the lever 15, with the now erect ribbon-guide, over to ward the printing-platen and in time to 'receive the stroke of the type. If the ribbon-' guide is to be arranged to oscillate in one di rection only, its pivot 19 could be arranged near one end thereof and the movement obtained through the lever 15 could be elimi-' nated. In otherwords, lever 15 is utilized to permit the ribbon-guide to be centrally pivoted and swing in either direction and thereafter move over to cover the printing-point.
To oscillate the ribbon in a direction opposite to that described with reference to Fig. 5, the pivot or shaft 19 is also provided with a pinion 22, Fig. 4, which is engaged by an arouate rack 23, pivoted at 24 and having an arm 25, that is en aged by the link 8 when the latter is move out of engagement with the arm 18. As will be seen from Fig. 7, the arms 25 and18 are spaced apart a distance to permit lateral play of link 8 between them, so that the pin 26, carried by said link, may
In .orderto determine the en agement of link 8 at 1ts upper end, a frictwri-retained slide 27 has a limited movement on the frame of the machine and has an elastic connection 28- with the link 8, so that when the slide occupies the position shown in full lines in Figs. 1 and 3 the link 8 will be drawn .into engagement with the arm 25, as shown in full lines in Figs. 4 and 7,-but when the slide is moved to the position shown'in dotted lines in Figs. 2 and 3 and in full lines in Fig. 6 link 8 will be thrown in the opposite direction and made to engage the arm 18, as indicated in Fig. 5. Slide 27 may be adjusted at will manually and independently of other operating parts of the machine by pressing the knob 29, Figs. 2 and 3, to one side or the other. The points of striking upon the ribbon will lie in straight lines parallel to the length of the ribbon and nearer one edge or the other, according to the direction in which the slide 27 is moved.
In order that the mot ement of the slide 27 may follow the manually-set ribbon-reversing device, the lever 30, which carries the dogs 31, movable alternately into engagement with the ratchet-wheels 32, carries an arm 33, extending upwardly from the fulcrum 34, and this arm 33 engages a lever 35, Figs. 1 and 3, fulcrumed at 36 and projecting forward ifito a bearing 38 on the slide27, so that each time lever 30 is rocked on its fulcrum the thro'wof arm 33-will transmit a movement to the slide 27 necessary to shift the connection between the link 8 and the arms 18 and 26.
In case it is desired to throw out theconnectionbetween the ribbon-feed shift and the means for inverting the throw of the ribbon, 1
so that themachine may be adapted either for this regular shift from one side of the ribbon to the other or for polychrome work at will, a flexible arm 39, Fig. 1, which swings with the lever 30 as a pin 40, which enters the arm 33, andwhich when withdrawn from said arm will permit the arm 33 to remain at rest while the lever 30 swings on its fulcrum to shift the ribbon-feed. In this case the re 'the lever 30 and the slide '27. That herein employed is merely for purposes of illustration. The polychrome ribbon of two colors a bis illustrated at 13 in Fig. 7. p
In describing myinvention I have used the I term horizontal in referring to the normal position of rest assumed by the ribbon to disclose the writing; but it is to be understood that this term is merely incidental to the use writing-machine selected for showinglth'e application of my invention. When t e stri mg-point is materially above the horizontal diameter of the paper-roll, the ribbons normal position of rest would preferably be ata corresponding angle to the horizontal, becoming substantially vertical in the'case of a downstrike machine The primary feature of the invention is to have the plane of the ribbon shift from a position substantially tangential to the paperroll or platen at the time of impact to a position substantially radial to the roll or perpendicular to the striking position after each stroke, while further features are to have the angular movement between these twojpositions take place on a'turning axis intersecting the ribbon, for which purpose the ribbon also has a swinging 'movement to andifrom the platen, tohave the oscillation take place in different directions in order to present different portions of the ribbon over the printing-point, and to provide means which-while causing the oscillation and presentation of sition at an angle to and removed from the tion.
