Description
Writers, of which the' following is a speci-` iiCatiOn.
@En STATES PATENT ,OFF-WE GEGRLGEBNPEILTONOF `o`ri`oneiirownl,` KENTUCKY;
Nrn-warren..
To-aZZ whom 'tfmaynoncemr i L. Be itlmown that 1, Grosor E. PEI-.Tom a citizen-.of the United States, .residing Vat Georgetown, in the "county of Scott and State of Kentucky, have invented certain new, and useful..Improvementsj in Type- This invention relatesto improvements in typewriters and more particularly:` to the ribbon mechanism thereof.
One of the objects ofthe presentinvention` is to provide an improved ribbon mechanism whereby the full width of the ribbon may be utilized and it is designed more particup larly as an improvement overV the 'construction used in the Underwood machine and illustrated, for example, in patent to W. E.
Barnard, No. 1,041,722, dated October 22, 1912.
A further object is' to provide a simple Y and practical ribbon mechanism whereby the ribbon may be positioned with respect to the line of impact of the type so that when multicolored ribbons are being used in either entire red, entire black, or a combination of these colors appear in the impressions. 1f, however, a single `colored ribbon is used then the full width of the ribbon may be employed.
These and other objects will be more apparentfrom the description hereinafter set forth when taken in connection with the ac! companying sheet of drawing illustrating one of various possible embodiments-of the invention. In this drawingFigure 1 illustrates in perspective such parts of vthe ribbon mechanism on an Underwood typewriter machine as is necessary to understand the invention, and showing the parts in position for utilizing one edge of theribbon. Fig. 2 is a front elevation of a part of the ribbon shift mechanism in a different position, while Fig. 3 shows the same parts in a third position.
'As is well known Vto those familiar with the typewriter art a ribbonguide 5 is actuated on the impression of each key to `move vertically upward into the path of travel of the type bar whereby the ribbon indicated at 6 is interposed between the type and the 1 paper at the instant of impact. This ribbon i guide is pivotally mounted at 7 to one end of an arm 8 ypivoted to the frame at 10 and actuated by a member 12 supported, from a universal bar frame 13 whereby it moves i :SPCGflatin of Letters Patent.

fore and aftwith respect toV the `machine at each impression. This member 12 is of general` U-shapeda construction` in horizontal cross-section, one arm of which is provided with a slot 14 in staggeredrelation with respectto an oppositeslot 15.
- Between these slotted arms isa member 17, as shown more clearly in Figs. 2 and 3, provided witha pin 18 at one side, adapted to coact with the slotted 4arm`14, while. on the opposite side is a compound pin 20 provided with an o'set extension 21 `adapted to coact withthe slot 15 in the position shown in Figs. 2 and 3, according to the extent of lateral movement given this member. This movement is accomplished by means of a link 22 connected' at one end to the member 12 as shown in Fig. 1, while its opposite end is pivotally connected at 23 with an arm 24 mounted on a rock shaft 25. This rock shaft is provided at its forward end with the usual oscillating arm (not shown) which, .when moved eitherto the right or left will cause a corresponding movement of the member 12. By moving this arm to half way position the parts occupy the relationshown in Fig. 3.
As the part 12 has la fore and aft horizontal'movement and the part 17 is moved relatively vertically at each actuation of the universal bar, it will be seen that the throw given to the ribbon guide 5 is controlled by the engagement of the pins 18, 20 and 21 with the slots 14 and 15. Thus the pin 18 in engagement with the slot 14 will permit- `writing on one edge of the ribbon 6 While engagement of the `pin 2() with the opposite slot controls the impressions upon theopposite edge. lThe pin 21 on the slot 15 however will insure the ribbon beingengaged lalong a medial line, and in this manner the scribed, in combination, a ribbonguide. a
universal bar associated Vtherewith adapted to move the ribbon guide vertically at each actuation of the type, a pairof 4coacting I y portions arranged in ydifferent horizontal planes, One orn said portions having a third part lying in a still diiierent horizontal plane whereby any one oi' said three portions may coact with slots in the other member to provide a different path o' engagement between the type and the ribbon. v
2. 'In a mechanism of the character described, in combination, a ribbon guide, a universal bar, intervening mechanism therebetween adapted to convey motion from the universal bar to the ribbon guide to interpose vthe ribbon between the type and the platen, said'inechanisin including a slotted member associated with the universal bar,
and a member provided withopposte and laterally projecting pins adapted to coact with the slots in said member, one of said pins having two `parts lying in diierenthori- Zontal planes, and means for moving the sliding member relatively to said pins whereby one or the other of said pins may be brought into engagement with the properv slot to control the path of impressions along any one ofthree desired portions of the ribbon.
In testimony whereof I aiiiX my signature in the presence of two witnesses.
