Application filed May 23, 1905. Serial No. 261,864.

To all whom it may concern.-

Be it known that I, FRANK A. YOUNG, a

' citizen of the United States, and a resident of so much of guide-bracket being Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writ y invention relatesrlbbon vibrators, guides, main ob ect is tomore especially to or-carriers; and its readily may be easily and withdrawn or removed.

'T the above and other ends the invention resides in the features of construction and combinations and arrangements of parts hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is an enlarged fragmentary perspective'view of the upper part of a type-writing machine and showing said machine'as is necessary to clearlyillustrate my invention, art of the ribbon-guide bracket speedily hon-vibrator embodying my invention. Fi 3 is an enlarged front elevation of the ribboncarrier detached.

In the drawings, 1 represents the top plate of the machine, above which is suitably mounted a platen 2. A vibrator guidebracket 3 is secured by headed screws 4 to lugs 5, depending from the top plate, said provided'with two vert1callydisposed' parallel arms 6, the rear sides whereof are formed with longitudinal grooves or 'guideways 7. An ink-ribbon 8 printing-point and is has its ends secured to a pair of ribbon-spools, (not shown,) one at each side of the machine above the topplate and forward of the platen, and-said spools are designed to be turned by an y suitable ribbon-feeding mechanism in order to feed the ribbon back and forth from spool to spool. The central portion of that part of the ribbon which extends across the machine between the spools in front of the platen is preferably normally maintained below the printing-point and is during printing operation moved to cover the thereafter moved back to again uncover the printing-point. This to and fro or'vibratory movement of the rib-,

7 provide a ribbon carrier or vibratorin which the ribbon may be and expeditiously threaded or engaged andfrom which it integral with said slide. being bro en away. Fi'g. 2 is an enlarged side elevation of a rib- 15, the front and rear faces of the finger 15 be-- are in the same transverse save for the offset point or end of the guard bon is controlled by a vibrator, guide, or carrier, which is preferably made of sheet metal and com rises a stem 9, a cross-head 10 at the top of the stem and consisting of arms extending laterally and upwardly from the stem, and a pair of slides 11, carried at the ends of the cross-head. The two side arms composing the cross-head are folded back on themselves at 12, and the slides 11 are thereby turned toward each other and engage the guideways 7 in the guide-bracket 3. The

. lower portions of the slides extend below and wardly and outwardly extending guard-finger 14 and an upwardly and inwardly extending guard-finger 15. The finger 14 is suported from the upper end of the slide 11 the bend or root a of the finger 14 being preferably The downwardlyexten'ding guard-finger 14 is preferably considerably longer than the upwardly-extending finger and is through the greater part of its length substantially parallel with the inner wall or edge of the guidin lower end the finger 14 flares or bends outwardly or sidewise, as indicated at 16, so that its lower end is slightly outside of or beyond the end of the upwardly-extending finger 15, which latter throughout its length is or may be parallel with'the inner edge of the slot 13.

he flare or offset 1 6, as best indicated in Fig. 2, is bent or directed rearwardly, so that the lower end of the finger 14 is also slight offset and isbehind the upper end of the gei' upper part of the vibrator and those of the ing inthe same planes. The arran ement is such that there is a slight clearance 0th outwardly or laterally and tween the free ends of the guard- fingers 14 and 15. The Walls of each guiding-slot 13, it willbe noted, are composed of members which plane throughout,

or finger 14, and this end 16 is offset outside or beyond the retaining-wall of the slot of which the finger 14 forms a part. It will further be observed that the combined lengths -slot 13. Near its from front to rear. be-

IOO

of each pair of associate guard-fingers exceed the length'of the slot 13 of which theyform a part. 'lheguiding-slots 13 are shown diagonally arranged, diverging from the top to the bottom, this construction being preferred, since it overcomes the objectionable slack at the lower edge of the ribbon commonly found where vibrators having parallel slots are employed. I do not desire, however, to be limited to the particular arrangement of the slots shown in the drawings. Any other angle of inclination may be used or the slots may be parallel, if desired. The lower end of v the stem portion 9 of the vibrator is provided with a pivot-pin 17, which isengaged by the slotted forward'end of an operating-lever 18,

which is actuated in a known marines-to cause the ribbon to cover and uncover the printing-point. Theufper ends of the slots 13 are closed by the bend'sor roots at of the doWnWardly-projecting fingers 14, and hence the ribbon cannot fly or jumpout of the vibrator during the operationvof the printingkeys.

Referring more particularly to Fig. 3 of the drawings, the inner edge of each slot 13 is indicated by the reference-letter b; the opposing edges on the fingers 14 and 15 by the let ters c and (1-, respectively; the lower orinner edge of the laterally-disposed free end of the finger 14 by e; the outer edge of the upwardlyprojecting finger 15 by f; the passage-way etween the fingers 14 and 15 by g, and the mouth of said passage-way by h. It will be noted that the edges f of the fingers .15 are directed inwardly toward the center of the v1brator,so that in the preliminaryo eration of threading the ribbon when the atter is bent around the fingers 15 the ribbon is given wide mouth or entrance 7!.

a tapering shape by the inclined edgesf. The flaring end 16 of each finger 14 is so disposed with relat on to its associated finger 15 that the edges 0 and f of said fingers form a lateral passage-way g, which is obliquely disposed to the main slot 13 and has a comparatively When the ribbon having been drawn taut against the fingers 15 is subsequently moved upward, it is directed toward the main slots 13, which it is caused to enter by the overhanging fingers 14- by reason of the inclined or flaring edges e of the latter, which tend to deflect or. guide the u per edge of the r bbon easily and smoothly through the passage-way g and thence into the slots 13. When the ribbon has once been brought into the comparatively wide mouth h of the passage-way g and is moved upwardly,

it is inevitably guided into its Plot 13.

In order to thread the ribbon in the slots in the vibrator, said ribbon is passed down between the laten and the vibrator until the top edge of t e ribbon is below the free ends ribbon just beyond or outside of the o1 the'guard-fingers 14. The portions of the ardfingers are then bent or curved forwar until they are beneath the ends of the fingers 14, considered from the front of the machine. The ribbon may then be moved upwardly and passed readily into the slot 13 between the ends of the'guard- fingers 14 and 15, and

after its upper edge has contacted with'the top of the slot the lower portion of the ribbon may be drawn in and over the lower guardfingers 15 until the ribbon is completely threaded or engaged in the vibrator-slots.

Preferably in inserting the ribbon it is drawn r taut against the outer edges of the lowersaid ribbon.- When completely threaded in v the vibrator, the ribbon, it will be noted, passes in front of the guard- fingers 14 and 15 and thence diagonally through the slots 13 and behind the wings 11*. In order to withdraw the ribbon from the vibrator, itis only necessary to liftthe lower edge of said ribbon upward until it is just above the free ends of the fingers 15, whence .it may readily be slipped out of the slots through the openings between the ends of the guard-fingers The fingers or hook-like members 15 are comparatively short, so as to necessitate but slight buckling or creasing of the ribbon When, it is threaded oru'nthreaded. The hooks 15, itwill be understood, serve as a support for the lower edge of the ribbon.

To engage or disengage the ribbon with the guide or vibrator has heretofore usually been tedious and difficult and has necessltated a protracted handling of the ribbon, thereby resulting in soiling the fingers of the operator to a considerable extent. employment of my resent invention, however', the operation 0 threading or 'unthreading the rib on in the vibrator may be readily By the and expeditiously accomplished with slight handling of the ribbon.

I have illustrated my invention as applied to a front-strike type-writing machine resembling in its construction the Monarch type-writer and have not, therefore, deemed it necessary to show and describe those parts of the machine which are not necessary to a complete understanding of my invention.

It will be understood, however, that the invention may be embodied in other forms of writing-machines employing a ribbon-guide of the class described or of any other description, for it willbe understood that in so far as the main features of my invention are concerned it is immaterial whether the ribbonguiding device vibrates or reciprocates or whether it .-be normally fixed against such movement, although I prefer to employ my novel ribbon-guide in a machine wherein it is reciprocated to cover and uncover the printing-point during the operations of the keys and leave the last letter exposed when the parts are in normal position. It is further to be understood that various constructional changes may be efiected within the scope of my invention.
