Application filed lpril 22, 190. Serial No. 425,455.

To all whom t may concern:

Be it known that l, Geenen it. lai'ru, citizen of the United States of Annales, a resident of the eity, county, and State el' New York, have invented certain new and useful Improvei'nents in Triax-ginal-Stop vices for 'Twelfth-ners, o which the follow-- ing is a specification.

This invention relates to marginal stopsY for typewriter carriages, by means ot' which the length ot' the lines are regulated,

of the margin or both sides in the superior manner to be more fully described hereinA after and pointed out in the claims.

In the accompanying drawings, l`igure l is a front elevation of an ordinary typewriter carriage to which my marginal stops are applied, parts being eut away to better show the mechanism beneath. Fig. Z is a plan View of the same. Fig. 3 is a trans verse section through the machinelor the purposeof showing how one ol the stops is oerated from the key-hoard. Fig. e, a rear e evation of the same iti whieh dotted lines show the changed position of the parts, when the mechanism in the preceding figures is thrown into action. Fig. 5 is a detail, pen speetive View of one of the stops. Figs. il and 'i' are inverted detail views of the inan- `ually adjustable stop mechanism showing the parts in different positions.

The carriage 10 is mounted to slide and tilt on a horizontal rail 11 at the rear, and may loe driven hy any suitable means whieh it is not thought neeesary to show because such means are common and well understood, and form no part olf this inventioii.

19 represents an `ordinary cylindrical. platen. In front ofthis )laten and below its axis is located a long, horizont-al ratchet bar 13 pivoted at its opposite ends in arms 34. This bar is provided With a rearwardly extending handle 14 at its right-hand end by means et which it can he turned on its longitudinal axis when shitting theearria lingers er hold 18 which hold and guide the writing paper on .the platen through the aetion or a spring 15 coiled around the rah/filet har. 13 aal; the el' the 4and it 'anged so that the width l the length of the hues eau a laelied to the arm and the free spring is )ar il. 'lhese paper guiding and end te the l holding lin gers lf3 are made integral with me stops 18 and l5', the lioriner limiting l leit lo right, and the latter limiting it from the lengti ol the trin of the carriage from right lo loft, whereby any desired width of marginal space maylie loll upon either side es alle nag Cach' stop held in sliding adjustment ou tirera et liar lil by means et a rectangular. sleeve Z-l whieh embraces the hai'A theliottom et" the sleeve a pawl l? is )riveted at 1T so that` its upturued end will. engage aT vertical ratchet 1G on the trout thee etuthe spring-aetuated ratchet bar 13.

Sis the carriage. moves from right to lett, when writing, il, earries the stop 18 along with it until the stop Einnes in Contact with a releasahle stop or hull'er Jlate 20, as seen in dotted lines in. Fig. l, which stops it aty any predeterinined Point thereby limiting the length of the line and allowing the space desired on the righlfhand side ot the page. `ll'hen it is necessary to prolong the lint` he- Lvond its normal lengtl'i in order to eomjlete a wei-il or i'or other reasons, the butler-plato 2O is made to yield to the Contact et the Wl', and to ne carried along' with the Stop stop lt'lOlll required distance. yl'his result is .'herl through the medium ot' a 'stop or hul er rehaising device Consisting olf a hey-lever 30, l'ulerumed at lll, (Fig. il) which lever when de ressed pulls down with it a vertieal delent har the. upper end et which acts; as a detent to holdl the builer plate 2() and stop the carriage normally in the position shown in l'ull lines in Fig. 4', so that (he plate will serve as a bull'er whirh cooperates with the stop 1H in stopping the progress olfthe carriage. 'The withdrawal ot this detent bar 25 releases the hullierqilate 20 which is then carried along longitudinulli7 ly the carriage the required excess distance, as shown :in dotted lines in Fig. 4. rl`he huil plate is secured to the vertical wall Z1 or tonplaie 22, hy screws 225 which hrough hm'izonlal oblong slots Q-'l havequal to the additional travel required. a spring lor retraeting the huiles-plate wh i the step and the carriage L new line. rlhe are tiroi "nt ...rar sis'ts the butlerllll() tlm right-hand ends plate 2O ttimugli tlie medium si ai cushion ing spijtig 28, the fr@ endl @f which bears against the edge of Recess 26 in 'the topplate 22, @n tha opposite side 0f the datent, liar 25 is a @am 2S sitzmtecljust belw its upper @ml and normally battling against the edge of tlite top-plate 'llflin tl'te datent bai" is pulletltlwn by .key-level' 30, this @am 29 `Slitltes fiwa'itl and. uiitlr the pltite 22, as seen in dotted lines, tlm-mela); the end the tlfatailt lizu pmjecting alim-' 1 the plate enough to tilt. :further: advance of tlm butler-plate 2t by mining in Contact with a Shoulder 29 farther hazel: 0n the un der sidi; of the plate $10 at the limer and of a recess 20 which i'eceives'tlia and 0f the (latent bar. @Vllen the cariage is fetunecl to start a new linfa, the stop 1S ieleases the butler-plate 2C', which plate is then returned by the i'eti'acting spring 27 until stopped at. of slots 2l, theieby liliM the detent 225 which is automatically forced up :mtl itetumecl te its original position by i s riin 32 actitig rectly upon the under sitle 0I i'eleasing keylevezr 30.
