In the drawings forming part of thisv specification, Figure 1 is a longitudinal sectional elevation of a front. strike writing machine embodying my improvements; one type action being shown in printing position, and the platen being shownlin `full hnes iii position vfor writing' lowercase-let ters, and in dotted lines at upper-case position. Fig. 2 is a detail rear elevation of the hell-ringing and line-locking mechanism. Vig. 3 is a sectional front view of the ma chine. l `igwfl is a plan of an adjustable stop for regulating the. margin at the left-hand side of the paper. Fig. 5 is an end elevation and Fig. 6 a plan of'a three-part adjustable tappetused in sounding an alarm and in successively locking the keys. Fig. 7 is a front view of the machine, showing the carriage tilted up to expose the underside thereof` and give access to the adjustable margin-governing tappets, the ribbo'n spools, and the carriage-spring tensionladjusting devices. '5, U1 f Throughout the views like parts are identilied by like signs.
The framework of the machine comprises.
side walls and rear walls forming a basev 1, and a depressedtop plate 3. Forwardly eX- tending type bars l are pivoted at their rear ends upona curved fulcruurrod 5 mounted in a segment 6, and stri ke rearwardly against aplaten 7. -The segment is radially slotted at 8 to receive the type-bar hubs; Each `type-bar is provided with a lower-case type 9 and an upper-case type 10, the latter being uppermost when the type bar is in printing position, although this relation may be reversed within the scope of certain features of my improvements, and the type-bars may be otherwisemounted. The type-barsmay be operated by any suitabe means, as for instance pull-links 11, extending rearwardly and downwardly from they type "bars, pendent levers l2 connected between their ends atl 13 to said links, a horizontal rod 14 whereon said 4levers are fulcrumed at their` v upper ends, horizontal links 15 connected at l 16 to the lower ends of said levers and exino tending forwardly, and key-bearing bell' upon a ltransverse rord 17 arms 18 connected .at`i519 A arms v bearing the keys 2l.

'The platen 7 may be mounted by means of an axle 25 upon a carriage 2G, which may vbe of any suitable construction, but preferably comprises upper land lower bars 27 and 28, the former provided in its underside with a longitudinal lgroove 29, and the latter in its upper side ,with a longitudinal groove 30; 'these bars being connected at their ends by upright bars 31 and 3,2Aformed integral therewith. An integral'plate or bar 33 vprojects forwardly from said connected bars, and at/its ends is formed with upright arms 34 and 35 in which the platen axle 25 is journaled. Embraced by the grooved bars 27 and 28 is a rail 36, set on edge and provided in its top and bottom edges with grooves 37 and 38, which are provided with bearing balls 39, whereon the vcarriage runs.
A feeding-in roller 40 may be mounted in rear of the platen upon links 4l rising from ears 42 on the upper carriage-bar 27; and
, said links may be provided with rearwardly extending lugs 43 for receiving legs 44 of a paper-shelf 45. From the front side of the plate 33 may project forwardly and upwardly extending arms 46, upon whose for- Ward ends is fixed a platen scale 47 provided with an apron 48 upon its rear side contiguous to the platen; the upper edge of said scale -being below the printing line upon the platen, and the scale and 4arms taken together forming a bail which is provided with hinge pintles 49 engaging ears 50 formed upon said plate 33. One or more pressure rollers 51 may be mounted upon an axle 52 mounted at its ends in said arms 46 aboutmidway of their length. Springs 53 are provided for pressing up said arms and roller, and springs 54 for the rear pressure roller` arms. A paper-guiding apron 55 may curve from the rear pressure roller beneath the platen to the forward pressure roller. Paper-guiding fingers 56, extending upwardli7 -in front of the platenand platen scale, and terminating at their upper ends at the top side of the platen, may be adjustably mounted at their lower ends upon a horizontal rod 57 mounted in arms 58 projecting forwardly from the carriage plate the plate 3:5, causing the fingers 5G to hug the platen, and preventing accidental dis' placement thereof along the rod 57. So far .as certain of iny present improvements arev concerned, however, other carriage mechanism may be adopted. Said groovcd rail 36 forms part of a movable fraaie, wher-eb;y the paper carriage is enabled not only to runl in letter-feeding direction, but also to move in a direction transverse thereto. This frame comprises, in addition to said rail (which ma)v be otherwise formed in some cases) rearwardliv extending integral arms G5, which are united yat* their forward ends by said rail, and a -bar (56, which unites said arms between their ends and is .integral therewith. Said arms are extended rearwardlyT from said bar Gli. formingcars 67 and (SS. which are hinged by pintles 69 inl bosse-s 70 and 7i which project inwardly from the tops of the side walls of the framework 1. The carriage together with its sup` porting frame may be swung or tilted up about said hinge, so as to expose the linderside of the carriage, as at Fig. 7. Said supporting frame may, however.l bc otherwise formed and otherwise movably supported within the scope of my improvements.
In the rear of the type bars and below the platen and carriage is mounted upon an axis or shaft 7 a pair of ribbon spools T6 and 77, said shaft being transverse and horizontal and parallel with the hinge 69 ofthe hinged carriage frame. and said spools beingV arranged on edge and side'by sidet The shaft 7 .5 is journaled upon 4and transxes the lower end of a downwardly directed arm or hanger 78 integral with the bar 66, of thc carriage frame, and having bosses 79 and S0 for suitably supporting said shaft. It will be observed that when in normal position the ribbon spools are inaccessible to the operator, buttliat ywhen the hinged frame is tilted 'upf-to the Fig. 7 position, said spools are brought to an'accessible position. for convenience in examining or adjusting or attachingt-he ribbon. or of detaching or replacing the spools, etc. yThe depressed portion of' the top plate is preferably cleft. as at 81, to make room for the spools, which in normal position dip below said depressed lV shaft 75, being retained by thumb-nuts 89 and,90; and colla-rs 91 and 92 may be xed uponthe shaft, against which the thumbnute mayb'ind the spools; lone spool being v bound by its nut while the other is left loose,
whereby the ribbon may wind back and forth from spool to spool. Other suit-able spool-1nomit-ing` and rotating means' maybe employed.
From one `epool the ribbon 93 is led forwardly and upwardly, as at 94:, then across the printing' point at the front side of the platen, as at 95, and then back down in front oit' the platen, as at 96, and thence back ito the other spool. At the front side of the platen are provided ribhon-g ,'uidin,9,n arms 97 and 98, formed at their upper ends with reversely inclined tipa` 99,100, the angle of each tip being about 415 degrees, for properly conducting` the ribbon across the printing point or field between itsl ascending,r and descending portions. Said arms 97 and 08 form part ot a ribbon vibrator, being connected at their lower ende by a cross-arm 101, whereby they are sup ported upon a bent arm 102, which extends bacliwardly beneath the carriage rail 3G, and at its rear end is pivoted by means ot a trunnion 1053 upon the forward end of an arm 10i project-ing forwardly from t-he frame arm' 7S and integral therewith. By this vibrator, the ribbon may -be lifted at each type-impression, as will be understood from Fig.v 1, to cover the printing point, and then depressed to uncover the saine; and since the vibrator is mounted upon the hinged traine, it is' carried up with the latter when tilted, thus vFacilitating the -reeving of the ribbon from the spools over the guidingarins 97 and 98. The invention f is broad enough to cover the construction of speciei andjvibrating devices, wliether they' are mounted upon an independently hinged trane from the hinged carriage frame or not, So as to be ewung'up with the la ttcr it desired, or so as not to ,swing up therewith. Said ribbon-yiln'ator is operatively connected to carriage-feeding mechanism als-o mounted upon. the hinged carriage-sulfiporting traine and cooperating with a rack 1011 on the carri said feeding' mechaninm comprising upiigl'it detent and feedingr doge M107' and 1tl8`, the latter normally in engagenient with the rack. The rack is mounted upon the rear endsof hinged arms 10S) and 110, the latter bein.g prolonged forwardly ot its hinge and provided with a; deprensihle carriagereleaae key 1.11. The dogs are n'iounted upon one, end ot a, roel-Shatt 112.
journaled in a bose 113 formed upon an arm 11.4; directed upwardly and forwardly from the Shifter-traue bar GG; and said shalt at its other end is provided with an oi'ierating arm 115, which at ite rear end is pivot-ed at 116 to a pendent link 117, wherel'y the arm is operated; said'pivot 11G being noru'ial ly v SubStantially, coincident with-the axis of the vhinge 69,01? the carriage 'supporting frame. no that the operation of the eacapenient mechanism is substantially the same whether the frame is in normal position or shifted up to Write capital letters. At its lower end saidlink is pivoted at 118 to the Iforward end of a rocker-arm 119, which projects forwardly from a horizont-al transverse roc-kshaft 120. Auniversal bar 121 is mounted upon the tops of a pair of arms 122 which ris'e from said rock-shaft, and lies in rear of the levers 12 of the type-actions, so as to be operated thereby, as at Fig. 1 the described universal-bar. :tra me beingr provided with a returning springr 123.
The connection between the ribbon-vilnat` ingr i'ueelnuiiem and the escapeztent mechanism consists of a. link 124, whose upper end is p ivoted to a forward extension 125 of the dog-rocker arm 115, and whose lower end is pivoted to a short arm 120 of the ribbon vibrator. -Iy this means, whenever the doigrof-lter is vibratcd by the keys, the vibrator is elevated to cause the ribbon to cover the printingr point; and upon the return ot the carriage-teeding;r mechanism to normal position, Said vibrator drops to permit the ribbon to uncover the printing' point.
The carriage may be propelled b v a Spring-barrel.12T, lying horizontally and mounted upon the lower end ot a stud 12S dependingF from the hinged earriagc-irame: a strap`129 beingattached to the barrel and caught upon a hook 130 upon the carriage bar 28. A ratchet wheel 131 and pallet 132 are provided for adjusting the tension of the spring, the former having a linger-piece 5%?, and the latter a. finger-piece 134, both of which in normal position project down- `\\'ardly," the ratchet-wheel and pallet. being mounted below the spring' barrel. When the carriage is tilted up, as at Fig. 7, access is given to therat'ehet wheel and pallet'. thu:-l jlacilitatiirg the adjustment ot the spring'. ly mounting; the spring barrel aml thel rarriaie-t'eeding nuahanism upon the hinged trame. the latter is permitted lo swing' freel)1 up and down. without liability ot deranginn' the carriagre-contlplling devices, which always preserve their proper relation to the carriage.
A\t each stroke of the carriage eseapemcnt mechanism the ribbon is 'ted by means: of the pa wl S5. -the latter beinjil pivoted at itv rear end lo the top ot a rock-arm 1235 tixed upon the univerSal-bar shaft 120.
llretorably advantage is also taken of the iuuginp; ot tht` carriage-nupport` to enable the latter to be shifted up and down to enable diilerent types to print. oru'ially the carriage and phten are in tlul towermos-'t position. as. iu full lines at. Fig'. l. thereby enablingthe lower-case types; 9 to print:
li\`hile,..by. elevating; the carriage and platen,
yadjustable stop,
.key is returned as indicated by the dotted circle 7, the uppercase types 10 are enabled to print. The downward movement. of the carriage is limited by an adjustable stop 136, threaded forwardly through an arm 137 cast upon the rear wall of the machine framing; the ribbon-spool bearing arm 78 of the hinged carriage-supporting frame being prolonged below the ribbon-spool shaft, as at 138, to bear against said adjustable stop. A shift-lever 139, bearin .a key 140, projects forwardly and upwarc ly from a transverse horizontal rock-shaft 141; journaled in the side walls, of
the base, and about midway of its length said shaft is provided with an upright arm 142, from which extends rearwardly a link 143, whose rear end has a sliding bearing at 144 in the upper portion ofrsaid cast arm 137 Said link is provided with a lug 145, adapted to catch a nib 146 formed upon a hook-shaped stop 147pivoted at 148 to the lower portion of said iibbon-spool carrying arm 78 in rear of the spool shaft. By de- 'pressing the shift key. the shaft 141 and arm 142 thereon are rocked, pulling` forwardly the link 143, and by means of the lug 145 and nih 146 swinging the stop down, until said nib is arrested by a stop pin 149. Continued movementfof the key, rock-shaft, arm and link then swings the frame arm 78 forwardly and the frame and carriage upwardly about the hinge v69, until the parts are arrested, with the platen in the dotted line position, b v the contact ofthe hook-stop 147 with the upper end of said cast arm 137 (which of course may be provided with an if desired.) After the capital type or types are written, the shift to normal position by a the hinged frame and car- A spring 151 lifts spring 150, while rlage return by gravity.
`,tlie"l1ookstop 147 until it is again clear of 137. so that the upper end of said cast arm to interfere it may not contact therewith with the upward tilting movement of thel carriage to the Fig. 7 position. During such tilting movement, the arm thereon are swung forwardly away from their cooperating' parts mounted in the machine base; so that at any time the'carriage may be given either a limited movement for writing capitals. or a tilting movement to expose the underside thereof. y
To provide for writing a line of capitals, I pivot at 152 upon said arm 137 a cam plate whose forward edge, which is eccentric to the pivot, is adapted to engagea bearingpiii 154 projecting from the frame arm extension 13S. so thatr by swinging said cam plate upwardly about its pivot, said arm is driven forward and the hinged frame and carriage elevated to the proper point for writing capitals. For operating said ani plate. I pivot thereto at 155. below thepiyot 152, the rear end of .a pull-link 156, which wardly 7S and parts extends to the keyboard and is there pivoted at 157 to the upper end of a rock-arm 158,
mounted upon a horizontal transverse rock shaft 159 mounted between the walls of the framework. t the left-hand side of the keyboard an upright lever 160 is fixed upon said rock shaft, so that a forward movement of said lever may lift the ca1nplate 153 to set the carriage to upper-case position. Forward and rear stops 161 and 162, the'former preferably adjustable, may be provided for said lever; and a double-acting spring 163, adapt-ed to bear against a pin 164 fixed upon tpe lever, may hold the leveragainst either s op.
The margin governing mechanism, by which term is meant devices which either positively limit the travel of the carriage or warn the operator that the end of the line is approaching, or both, includes a rack 170, mounted beneath the carriage, being attached by screws 171 to the bottoms of arms or ears 172 depending from the carriage plate 33. Said rack is provided with a series of teeth 173, for enabling the tappets or 'stops to be fixed at Adifferent. positions, according to the width of the left-hand or right-hand margin desired on the page of writing. The means for limiting the return movement of the carriage, and thereby regulating the left-hand margin on the paper, com rises a box-like slide 174, fitted upon the rac r and seen at the left-hand of Fig. 7, and also at Figs. 1 and4, and having formed thereon a stop 175,y projecting upwardly from the slide, and in position to contact with the forprojeoting end of. an arbor 176 mounted in the carriage-guiding rail 36 about midway of the length thereof, thereby, to arrest the carriage. Said slide is provided upon its underside'with, a pawl 177, having an upwardly projecting tooth 178 r insertion in any of the notches in the rack,
so that any desired. width of left-hand-mar' gin ymay be secured. The pawl is provided with a handle 179. and a spring 180 for pressing the tooth 17 8 into engagement with the rack. By withdrawing the tooth, the slide and stop may be slid freely along the rack in either direction. The pawl is pivot-ed vertically. upon the slide at 181. The rack is provided upon its underside with a series of graduations 182, and the lefthand edge ofthe slide 174 may be adapted to cooperate with said when said edge coincides with any graduation on the scale. the first letter of the line of writing will fall beneath the corresponding graduation on the platen scale 47. It
will be observed that normally said slide, as
graduations, so that well as other tappets upon said rack, are in an inaccessible position beneath the carriage, while the scale 182 is out of sight; but. that upon tilting up the carriage, as at Fig. 7,
the seule is brought into full View, ,and read) aeeess is atl'orded to 'tl'ievfslide and its pawl. it'or adjusting the same lo'ngthe rack. Se far as this feature of my improreinentsis concerned, any suitable rack and otherparts ot margin-governing mechanism may be adopted. within the scope of my invention. The novel features erta-innig to the i'i-iargifi-f governing details lherein shown are,\.`ho\'v= ever, preferred. l' 1 yf A bell 183, in rear ofthe rail 36,'is hungby# a strap 184 upon the bar G6 of the hinged" earriagre-supportingr traine; and 'a elapper 185 is horizontally pivoted at 186 upon the rear side of said rail, normally resting upon a stop 1ST. Ihevelapper is litted by anfarin 198. having u long bent linger 180 underlyine' the elapper, and secured by lrivets ,1510 upon a head 191 formed upon the rear projet-ting end of the arbor 171i, so that by ro tation of the arbor. thearin"lSS rises and littsgthe elapper. It will 'be observed thatD the arbor extends horizontally through bosses 192 and 193 formed upon the `rear and Al'ront sides ot' theurail, whereby a" long bearingr is given, to avoid binding. For rotating the arbor to lift the bell-chipper, a tappet- 1'91- is mounted upon a slide 195 mounted upon the rack 170 and resembling the slidel l-l. Said tappet extends rearwardly (Figs. 5 and G) from the top of a standard 196' rising troni the forward edge of the slide; said standard elearingr thev forward end ot the arbor ITG, but said tappet being in position to engage a pallet 197 projecting upwardly troni the tip of the arbor. During` the letter` 'feeding movement. of the carriage, the tappe-t engages the pallet and rotates the arbor. lifting! its arm and the bell-clapper. until the t'appet passes -over the pallet. thereby releasingl the saine, and lthe bell-chipper being lei't unsupported, AFalls and strikes the bell, y to notiiyY the operator that the end of the. line is at hand. The slide 19:3 is provided i with a pawl 19S. haring a meh-engaging tooth IJl and a spring 200. whereby it ma)v be adjusted along the raelc, to regulate the l rifrht-liand maigrin upon the paper.
["or loelfing the tvpe-aetions or otherwise rendering the keys inel'l'ective to operate the types. l provide. prei'eiabl)v upon the belleoutrolling slide 193. a tappet 201, a short distanee to the right of tappet 104. which liesl elose. to the upper side ot the slide, but proieets .suilieientliv therefrom to engag a pallet 2112 provided upon the, underside of the arbor 17V. wherelrv the arbor is rocked in the opposite direet'ion to that already deseribed. therebyr produein; no elileet upon the bell-elaplwr. but swinging into effective position a tumbler JOI-. projecting upwardly trs vhe head 191 ot thefarbor, and preferable-integral with the arni 188. Said tuinbleil thus brought dii-eetl;v beneath an extension "l0-l projeeting forwardly from the 'ating farm 195 lot the carriage-feeding4 and :iblain-vibrating ineelnlnisin, thus preve tin'g' operation of said meehanism and hen'ee ofthe iniirersal-bar-and the type aetiois. sideotI sa-nl extension 201, as seen clearly at Fig. Q. in which position it maintained by a spring 205, coiled around a reduced portion of the arbor between its ends; said spring being of light tension, and overb'l- .aneed bythe weight fof thev beltcla per, whereby ,the arbor is returned in one irec tion b the spring` and in the other direction by the weight ot' the elapper. Said arbor 1113 is slidably journaled in said carriageguiding rail. and its head 191 isengaged by the, Forli'ed lower end of a rock arm 20G, fixed upon a rook-shaft 207 journaled at? its end portions in brackets 208 projecting l-roui the rear side ot said rail,.and provided at' its tips with buttons Q09. whereby it may beturned. 'By this means th arbor may be drawn rearwardly to a sniiicient extent to enable it to elear the tappets or stops mounted upon ythe raek 170, thereby enabling a. few nliore letters to be added at fthe end of the line, or enabling the carriage to run farther upon itsl return stroke.l so that thetirst part ot the succeeding line may be Written in the lett-hand margin upon the paper. A spring 2n) is provided upon the shaft 207, for returningI the shaft, together With the arbor, to normal position.
seeond or final keyloeking tappet 211 ma)Y be t'ornied upon the slide 195, at the right of the first line-locking tappet-20l, this tappet operating in the same Way as the ta ppet 201, and prevent-ing the writi ol any more letters at the end of the line. ln lsome eases, however. this tappet may be omitted. The slide 195 may be of suilicient length to areonnnodate the three described tappets, or it desired each may be mounted upon a separate slide. Upon its underside the slide may be recessed, and the edge 212 ot: the reeess may serve as an index to eooperate with the scale on the margin-gage rar-li. tor setting the slide to ring the bell or loel; the. line at any desired point.
.Ear-h of the tappets, as well as the sto 175, is preferably formed upon its rear si e with an oblique tace, as 213 and 214, which di-ufinrr the usual carriage movementseam back the arbor against the tension of the spring-.210, out ofthe path of the tappets or stops. so that the latter are ea'ch efeetive in only one direction.
.lt will further be observed that the rod 57, whieh supports the collars 59, fromwhich extend the paper-guiding fingers 56, is mounted in a relatively inaccessible position below the platen scale and upon the underside ot the carriage, so that when the earringe, is in normal position, it is diilicult to reach the collars to slide them along the Normally said tumbler stands at one 470 irs rod; but that when the carriage is tilted up, said collars are more accessible, and their adjustment facilitated. l lVide variations may be resorted to with- 1n the scope of myinvention, and portions of my improvements may be used without, others.
