SPECIFICATION formngvpart of Letters Patent No. 1964,34@ dated d' i1 yApplicationfiled Miei-ch 25V 190i?.

To a/Z whoml it may concern:

Be it known that I, Joiiiv `W.BOOTH, a citi'-N zen of ythe United States, residing at lVash4 ington, Franklin county, Missouri, have in vented a certain new and usefullmprovement in Type-,Writing-Macbines, of 'which thefollowing is a full, clear, and exactvdes miption, such as will enable others skilled inthe art to which it appertains tomake and use the same, i

reference being `had 'to' the vaccompanying drawings, forming part of, thisfspeciiication,

-in whichfigure l. is .atop plan view of. theI ribbon.

"Fig, 3 is a fragmentary detail looking from above, the` ,rollers being shown in section, talren through the grooves thereof.- Fig d is afragmentary elevation, partly in section, of the inner end of .theribbonreceptorcle;` andllig. 5 is an endY elevation showing said inner end of thefvribbon-receptacle. l d r u rlhis invention relates `to type-writing mau mechanism of such machines.,

fdp object is to provide a typewriting machines, and more particularly to the ribbon i chine with. 'a ribbon mechanism fdr endless ribbons,y the storagereceptacle being of simple and convenient construction and the feeda rolls being so -locatedvvith respect to the re.- ceptacle that the incoming ribbon is engaged by first one roll and ,then the other fora considerable time after the ribbon enters the receptacle, whereby the ribbon -is evenly-laid in the receptacle in layers of substantially uniform length, thus storing the ribbon in the receptacle in such manner that it can be uniformly withdrawn from the receptaclea vlo these ends and also to improve generally upon devices of the character indicated the invention consists in the various matters hereinafter described and claimed' in the embodiment of the invention illustrated in the accompanying drawings the mechanism is shown as applied to an Under- -is driven in a given direction.

known, -lt will kbe apparent, however, that the present eclianism` can without departing from 'the spirit ofthis invention be applied to machines of other-types thani that illustrated'.

me'relyidle, rollers and the yguides 2. being p illustrated asr eyes orhoolrs in order` to cause the ribbontov travel linesatdiderent elevations, '.llhe ribbon-guides will of course be varied to suit the particular tppeof machine to which the present mechanism is applied.4

Ata suitable point' in its 'length the vribbon passes between suitabledriving-rolls 3, prefu erably constriictedof soft rubber or othermaterial,l b v means of which the Arolls can properly grip the ribbon, and it will bemanifest that asthese rolls are rotated the ribbon These drivingrolls receive their motion-from a suitable shaft Il, which can be operated b v the typebars in aV manner which is Well understood,

Asuch a' drivingshaftl being commonly applied to ribbon mechanisms and this shaft v being usuallyfoperated by the type-bars., As

here shown, vthe driving-shaft i is provided with a gear 5,-which meshes with a pinion 6 upon the shaft T, upon whichone of the driving-rolls il is amounted, saidshaft being preferably iixedly located-41. e., journaledin fired supports. A The sh ft 8, which carries the cooperating driving-roll., is provided with a pinion 9,'which meshes with a cooperating pinion l0 upon the said Vshaft 7, whereby through the connections indicated the gear 5 serves tofoppositely drive the said drivingn I, rolls, thus resulting in the desired feed of the ribbon. Preferably the shaft 8 is journaled `in the arms of a pivoted frame 1l, whereby v erabie pertion of its vribbonl to the other side of the recaptar/ie.v

ably held by a suitable spring l2 under tension against its cooperating driving-roll. Y The ribbon-receptacle 13 comprises a boxlikemember openat its inner end, the ribbon being contained Vin said receptacle. in layersv which extend across the sanne, as clearly shown in Figs. l and 2. The driving-rolls 3 project -for a considerable distance into the open end of said receptacle, and aoonsiderable portion of the peripheryof each of said guide-rolls within the receptacle is exposed to the incorning ribbon. Guide-arms le', projecting -inwardly from the side vweils of the lreceptacie, are received in circumferential grooves l5 in the drivingrroiis. ribbon having been initially laid in the receptace acts somewhat as a` spring and tends to press against the arms le and inner portiens oi. the driving-mils 3. [as ribbon is fed into tbe recep@ tacle by said roii's the incoming ribbon hugs the ernaoseciv peri naryof the inner portion of a roii, and is thus carried by said roiito' ward one sioe of tile receptace, the ribbon `being"property guided by 'the ap ropriate.

'out of the receptacle.

The mechanisin' 1s simple; in its construction and can be readily applied to the ma chimes now upontbe market.

l am aware lthat minor changes in the construction, arrangement, the several parts lof my device can be made and substituted Vfor, those herein shown and 'described without in the east departing from the nature and principle of `my invention.
