Specification of Letters Patent.

Patented Feb. 5, 1907.

To atlwhbmiit may concern.-

Bejit known that I,- JOHN. A. WHERRY, a citizenjo f'the United States, residing in N ew Orlea'nain theparish'of Orleans and State of Louisiana, haveinvented certain new and useful Improvements in Type-Wri ting Ma chines; of which the following is a specification.

This-invention relatesto the ribbon-vibrating devices of type-writing machines.

'flhe-object of the invention isto provide simple, inexpensive, and easily-a plied and ftlng. the

,to cause the type impressions to bemade ialongl eitheredge of the ribbon, especially iwhere the edges are differently colored. "According to my invention I substitute for the single-piece ribbon-carrierwhich is usual inthe Underwood and otherwritingmachines a ribboncarrying member comprising two parts, the lower of which engages theusual vibrating lever and the upperof which carries the ribbon andslides up and down upon the roller to bring diiierent edges .of the ribbon over thepr'inting-point, the extent of throw of the ribbon at the type-strokes being the same in all cases. Upon. said ribbon-carrying member I provide a third part, which is adjustable to effect the shifting of the upper or ribbon-carrying part, and this third member is controlled by means of a finger-piecemounted upon the framework, so that by moving the fin er-piece in either one direction or the other t e ribbon is shifted to "bring one color or the other into use.

'Other features and advantages will heroin.- .aft or appear.

Int-he accompanying drawings, Figure 1 is a rear perspective view of a part of the U derwood front-striko type-writing machine rovided with my improvements, the arts eing adjusted to bring the lower color- Jand of the ribbon over the printing-point. Fig. 2 is a view of the lower of the two parts, which together form the ribbon-carrying member.

.justment seen at Fig- Lower-case and upper-case types 1 and 2 are mounted upon bars 3, pivoted upon-a rod 4, to strike against the front side of a platen 5. The bars are mounted in a segment 6, connected-to a framework 7 and having a type-guide 8, the" type-bars having heels 9 to )ush rearwardly a curved universal bar'10, ixed upon a horizontal moving frame-11, the latter having anarm 12slotted to engage a wrist 13 provided upon a forwardly-extending lever 14, which vibrates up and down at every type-stroke. Said lever is mounted upon a bracket 15, secured u on a rail 16. Upon said rail runs a roll 17,- elon ing to atraveling frame, (not shown,) which carries the platen 5. Said rail and platen-frame are shiftable up and down with the platen to enable the diil'erent types 1 and 2 to print.

per color-band 1S and a lower color-band 19 is threaded through eyes 20 in a ribbon-carrier (designated generally as 21) and provided with a vertical shank 22, which is inserted in a socket- 23, formed upon the upper end of a stem 24 so that said ribbon-carrier can slide up and down upon said stern. At its lower end the latter is detachably pivoted at 25 to the forward end of the vibrating lever 14-.

One link 26 of a toggle is pivoted at 27 to the stem 24, and the other link 28 is pivoted at 29 to the shank The links are pivoted togetherby means of a pin which is formed with a profecting eye 30, whereby the toggle may, be opened, as at Fig. 4, or closed, as at Fig/'1. Through said eye loosely extends a vertical finger or bar31. bent down from a horizontal rod 32, sliding in a guide-piece 33 upon the framework, provided at its outer end with a finger'pieco 34, whereby the rod may be slidden endwise or in a direction at right angles to the direction of movement of whereby the lower color-band 19 of the rib- TOO bon is caused to cover the printing-point at the type' strokes, Fig. 6. When, however,

'- 'said -finger-piece is thrustin, the toggle is opened, Fig. i, andtherihbon-carrier 2-1 is brought down until guide-ears 35, formed thereon to impress the type-guide 8, are a1- rested by contact with the top of the socket :23, whereby the ribbon-carrier'is brought to 7 its lowermost position and the upper colon band18 is caused to overlie the printing point'at the type-strokes, Fig. 5.

, 1 .It' will be seen that the device 26 28 comniunicates movement during the type-strokes from the reciprocating part 14 to the ribboncarrier 21 and is adjustable relatively to both,

said carrier and said reciprocating-part, so as to shift sa d carrier either toward or away from said reciprocating part to cause different portions of the ribbon to overlie the printpoint, that the device 2628 is adjustable re ativel'y to both the ribbon-carrier 21 and the stem 524 for shifting the carrier upon the stem, that either the stem 24 or the lever 14 'may be regarded as a support for the ribboncarrier 21 as well as for the toggle 26 28, that the finger-piece 34 is stationary or inactive during the type-strokes, but is connected to means for effecting relative shitting move ments of the parts 21 and 24. It will be seen that atFig, 1 the point of connection of the carrier 21 to the reciprocating part is higher than at Fig. 4.

- adjustab Variationsmay be resorted to within the scope of my invention, and portions of my improvements may be used Without others.

Having thus described my invention, 1 m 1 1. The combination of a ribbon-carrier, a part which reciprocates at the type-strokes, and a device communicating movement from said reci rocating part to said carrier, and lb relatively to both said carrier and said reciprocating part, so as to shift said Lcarrier either toward or away from said reciprocating part to change the point of connection of the carrier to the reciprocating art, and cause difierent portions of the rib on to overlie the printing-point.

: 2. The combination of a ribbon-carrier,- a stem upon which said carrier may slide, a reclprocating part actuating said stem, and a device between said stem and carrier, and adjustable relatively to both for shifting said 4 carrier upon said stem, was to cause ditier- '55 4. The combination of aribbon-carrier, a

reciprocatingsupport upon winch the carrier is mounted, and a toggle connecting said support to said carrier for \shifting the latter upon the support, so as. to cause differentportions of the ribbon to overlie the printingpoint, and a finger-piece upon the framework and connected to said toggle.

5. The combination of a ribbon-carrier having a shank, a reciprocating stem having a socket to receive said shank, Iinksforming a toggle connected to said shank and stem for sliding the shank within thestem, and a stop for limiting the shifting of theshank at.
