le it known thet we, MA'RsnMAN W. HA- znn end Bronnen W. Untis, citizens ot the United States, end residents oi New York, N. Y., end Rutherford, New Jersey, respectively, hef-'re invented e nei/xT end useful linproveinent m' in itype-liriters, of which the iollo'iving is e speciiicetion.

The present invention provides e typeo Writer construction which though simple and .cheep is nevertheless edepted to the menofecture oi typewriting mechenism or ma.- chine of ehoient end reliehle operation.

The nesent typewriting rnechine relates to t, thet class Which employ e so-celied type Wheel or type carrier, selectively shiitehle through various ongles by the manipulation oli the lreys of the key hoord. The type cerrier of the present machine is shown pro-- vided with e double row of types corresponding to upper and lower type fonts, ineens essoceted with the carrier enabling the latter to be mhnuelly shifted so that that row oi types normally beyond the plane of the printing point may he 1Drought into alinement therewith. G'bviously; however, the type carrier may support e. greater or lessnumber of rows of type.

@ne of the most important features of the '.30 present invention relates to the construction and mounting of this type carrier and of the mechanism combined therewith, whereby the selective angular movement and ultimate positioning of the carrier is accomplished. This mechanism embraces stop devices which comprise meens sssocieted with the key levers end moved to a, position hy the opere.- tion of the letter, such the-t content with the y positioned stop mechanism is mede adjacent e0 to it-hetype cerrier; the illustrated machine includes a series ot stops shiftehle into en operative position lying in or immedietiely contiguous to the line passing through the printing point. Such s. location for the positioned stops is enventegeous in that it tends to prevent the vibration oi the type cerrier when y/the letter comes to rest ,with the selected type et the printing point, thus holding: the type end consequently the type carrier hrm 5,0 end motionless in its printing position et the time ol" the impression. To the seme end, that is, for the purpose oiE minimizing the ci"- fects ol resilience in the ports and securingr it meximurn rigidity, the type csrrier is designed to trevel in e guide wey provided for Specification of Lettere Potent.

it. -The present construction is thus clearly distinguished from those in which the type carrier stop mechenisni is on the opposite -side ol the type carrier exis, possessing edvantages thereover in that the type carrier may he inode longer und hence embrace a, greater n umher of types in e row than is customarily present.

lThe present invention also includes en independent stationery anvil es contredistinguished from those constructions in Which the type carrier guide performs such function.' y

Another feature ol the invention relates to le, simple forni olt supporting treme lor maintitining the type carrier and its associated me -hunismy es well as various other operetive parts, in their iessenihled positions.

'These various features together with others entering into the present invention are illustrated in the drawings accompanying tlieprescnt specification in which hodying the present improvements.

A'suitehle supporting frame is provided for assembling' ond holding,V the various erts oi' the mechanism. ln the form thereo here shown, it comprises e hase piece 2 forwardly from which extends en open rectangular treme 3 defining the space for the key hoerd (comprising the usual keys ut the end of key levers.) Prel'erelily the side pieces el of the treme 3 are suhstentielly of the contour indicated in. Fig. 2, the inclined upper edges correspondingl to the inclined plone of the key system form ation und constituting` side guards for the key hoord. Oi course, the frame with the various perte, standards, etc., thereof, may, when desired and convenient, he cest in one piece, or such parts may he seperote sind independent from :each other and fastened together.

lrected upon the bese plete 2 is o supplemental ironie 5 comprising e cross plot c 5 on Wiichere erected posts 6 :it whose upper ends is plete 7. l A. guide for the type carrier is designated Figure 1 is e pleo 'View of e typewriter emis o. detail plan View of the type carrier, itsy project upwardly ing uponthe edge-oi?. an openingin the supV -plementary frame late 5', through which said portion'lSis slic able. Guide ins 14, 14 rom the, upper p ate 7 and register wlth openings in the arms 10, 10 of thetype carrier guide. Extending lengthwise o the'arcshapedportion 9 of the said guide is a guide slot (the guide may be in two parts to form such slot) along which'arni ,16 is adapted to travel. Arm 16 together anaxially extending portion at its free o end (oonstitl'iting` .the type carrier proper) are preferably made in one integral piece designated by l17. Said axially extending portlon, or type carrier proper is here niade 1nl sect/91,' like form and its arin 16 `is pivotally' l mounted `at 18 upon portion S of the guide so asgto turn about an axis coinciding with the' axis of the are shaped portion of' the guide.

- 'The uid-el slot in the latter serves to define ltypes Athere may be a'row of upper'font types the p ane of the angular travel of the carrier and the walls of the slot' prevent the dis placeu ment. of the carrier sector axially of its axis ol movement. l

left of the printing 'derstoodf therefore, t iat the cross bar 3S at arnr located beneath the carrier Vguide and whose shalt is suitably journaled in parts of the machine framing substantially coincident with the axis about which the carrier turns.'

This flier arin carries a pin 27 which enters an opening in the arrn of the type carrier, causing the latter' to inove in unison with the ino'venients oi' the arin. The arin may be swungtoward the right or toward the left from its centrahposition (in which central position in alinenieiit` with the' ty. e' anvil it is indicated in Fig. 1) through t e i`ns'trumentality oi operating levers 29 and 30. These levers 29 and 30 are secured to res ec 'tive rock shafts 31 and 32, journalet in"- proper bearings which are secured to the supplemental frame 5 and each carries at 'its upper end a pin 33. When' the ther arm is in itsy central position, theseapins lie against the opposite sides oan enlarged portion 34 ofthe llier arni 25 at 'pointsy somewhat forward of the ilier arin axis, thus tendingr to position the arin in its correct central position. .Upon the backward niovenient of either ol the said operating iev-ers, (effect-ed by means which will be presently described esl the pin-33 thereon is brought into contact with the wall or edge oi" a laterally elongated ortion of the iiier arm and throws the utter to the right or the left, as the case may be, positioning the selected type on the ty e carrier at the printing point. Between t ie 4' portions 31 and 35 ol the arni at each side is an inwardly extendingnotch, substantially as indicated, to allow the pins on the operat` ing levers l'reedonr ol' movement. The rock shafts 31 and 32 are returned after actuation and release, by suitable springs '36, inter0 posed between radial pins on the respective f shafts and portions'of the 4machine frame; thls backward motion ot the rock shalt (through the contact oi the pin on the opel-at'- l ing lever extending therefrom with theedgo ol the portion 31 of the ilier arin) returning the [lier arm to its central position.

lt is evident that .the flier arirn inust be swung througlr diilerent angles in order to bringl selected types in the row thereof on the type carrier cmisecutively to the printing;

For thls purpose each rock shaft 311.

point. and 32 is provided with a corresponding arm 37 which carries at its vlree end a cross bar 38 lying over the key levers, the cross bar 38 for the actuation of the shalt 31 extending laterally above the key levers to the right of the printing point ,while the cross bar forg'the actuation of the rock shaft 32 is similarly;V positioned with respect to thevkey levers at thc.

one side of the machine is a substantial `du- (designated withoutdiscrimination by 39),

of that at the opposite side 'thereol ,struction 'eenige are iulcrinned intermediate their ends and suitably mounted to conline then to a. nioveincnl in the planes ol the respective levers. ln the construction here illustrated, each of .the lrcy levers has its lower edge notched,

such notch fitting over a knife edge or l'nlcruni har rl0 (one or more) secured to the base plate of the suppl rting` frame, and the. several lgley levers being located in the spaces between parallel guide pins. Two series ol such pins are shown, one 4l on one leole the fuicruin bar and another on the other side thereol these pins being` close together to prevent the Vibration. oi the levers.

@ne of the important features oi the invention to the stop mechanism conend tho positions which the stops assume in. controlling the position ol the typev carrier when turned by the depression ol" a in this instance the respective stops,- in the forni of let bars, are each adapted to be shifted to its stop position by n the depression eta key, there being a stop stop. i

'bar e3 cor espornlingg,y to each key or key lever. The series olystop bars are mounted to move vertically in appropriate slots or lquille ways in plates 7 and '5, these guide ways being disposed in an are just within and below the portion oi" the type carrier guide. The radins ol' this is such that, when a stop is elevated and its upper end thrown across the path of the lli-er arno. 25, contact of the latter will be made with the stop adjacent to the pin 2? ci the arm, that very close to the type carrier. lvibration ol" the arni and the carrier in conseqin-nice ol the arin striking the projected stop is thus niiniinized and the de pressed low holds the arm tightly against the torni, since such lforms answer every purpose and gnideways therefor are cheaply niadeh slotting being' cheaper than drilling,

Motion is transmitted from the inner' end ol each hey lever to its corresponding stop bar by the inipingement ol' the upper edge of the former against the lower end ol'A the har, it beingr observed that the lower ond portions ol the stophars as well as the inner ends of the key levers are of such conformation, or are so bent, as to cause the proper copcration ol' nach key lever with its associated stop har. bloopers (1:3, -fl are scoured in position lo retain the stop bars in their guide slots and confine their nim/ement to a longiludinal or f A in ai endent ol' the type carrier guide located ist behind the type carrier and in the plane ot' movement ol' the type haxnnnr, the anvil being lixedly sccnred to the upper plate ol the machine traino.

should bc slated that while the arni lli jpe carri@ is closely, though, slidably7 to the guide slot in the guide7 the axietonding portion ol the type. carrier is indei' ie stop are of preferably flat' l l i i 'along which said arin spaced at a suiicient distance from the outer or convex lace ol' the guide as to permit vthe location of the anvil between such face and the type carrier proper. rl`his is indicated in Fig. el in which the dotted curved lino between the full lines representing the outer faces of the guide, and the typo carrier proper corresponds to the inner or concave face of the latter. The anvil is rigidly al'lixedto plato 7 comprised in the supportingr frame of the machine, the outer end ol" theanvil being upright, position aforesaid in the plane ol vibration oi the t \'p -,-haininer and innnediately behind the types on the type carrier which have been brought by the operation of the machine successively into position for printing.

lt will be noticed that the key lever system comprises substantially parallelly disposed key levers, the lulcrun'i bar or bars of the key levers being straight bars and the inner ends of thekey levers being bent to properly cooperate with the lower ends of the stop bars, as aforesaid.
