' Patented Feb. 13, 1906.
lecl February 20, 1906. Serial No. 5.901. v
To (LZ/f w/tom it vnf/1,3' concern; Be it known that I, BYRON A. BROOKS, a citizen of the United States, and a resident of i the borough of Brooklyn, city of N ew York, l in the county of Kings and State of New York, have invented certain new mid useful Improvements in Type-VVriting Machines. of which-the following is a'specification.
The present invention relates, primarily, to the type-bar and shifting-platen mechan# ,isms of visible-writing machines.
One object of the invention is to pivot the type-bars sothat they will lie normally obliquely tothe hcrizontalplane of the machine i 5 and swingrearwardly and downwardly and strike the platen at a common point between the topmost and foremost portions pf the platen,V preferably about midway 'ofA the front uppermost quadrant of the cylindrical 2o platen. 'y
Another objectof the inventiony is to provide ty'pebars with two or more types and to shift the platen obliquoly to receive. the uppercase characters.
Other objects will hereinafter appear. y To these ends the invention consists of certain `features of construction and combinations of devices hereinafter more fully described, and particularly pointed out in the appended claims. i
rlhe preferred form of the invention is illustrated in the accompanying drawings, forining part of the specification, in which Figure 1 is a plan view, on a reduced scale, of a type-writing machine in which my improvements are embodied, there being but four type-bars shown, however, and the inking-ribbon and its operating mechanism and other parts being omitted. Fig. 2 is a cen jdral vertical longitudinal sectional view on a different scale and showing two typebars and' their operating mechanism, and Fig. 3 is asimilar view with-'the platen in shifted position.
The saine part will be found desie'nated by the same numeral of reference in al views.
1 designates a suitable framework or base: 2, side arms or risers at each side of the base; 3 and 4, supports for type-bar hangers, the said supports being in the form of segments of rings arranged to be concentric with the printing-point, the plane or planes of the segg scribed.
ments being inclined to the horizontal andv the said center or printing-point being at the l upper front side of the platen, hereinafter de'- 5 and 6 are standards'by which the supports 3 and 4, are connected with the sides and also with a cross-bar 7 of the base or frame 1;y S, overhanging` brackets secured to the top plate of the base 1 at the rear and projectin forwardly of the machine,'said brackets gbeing united at their overhanging ends by a cross-bar 9, to. which is secured a tubular bearing 10, extending longitudinally of the machine and at' about the same angle 'to the horizontal as that formed by the typebar supports 3 and 4'.'
11 and 11a indicate, respectively, front and rear rods or tracks for the carriage, said tracks being parallel and extending transversely of the machine and being supported;Y
respectively, by arms 12 and 12?,pro`ecting, respectively,from shafts 13 and 13*1L W ich are journaled in the brackets' 2 aforesaid. The arms 12 and 12a are equal in-length andA roject upwardly and forwardly of thel mac ine from their respective shafts 13 and 13a, and said shafts are arranged with the rear one hi her than the front one and parallel to each other, so that a plane passing through the axes thereof is parallel or substantially parallel to the planes of the type-bar supports 3 and 4.
14 indicates curved links pivotally connected 'at their ends with' the ends of thev corner, where it is provided with a ringer-key 18. The platen-carrier consists of a carriage 19, formed of end pieces 20', a front bar 21, and
an inverted-U shaped or channel bar 22 at the rear and three rollers 23,- oneof'said rollers being atthe front of the carriage and near the center thereof and the other two bemg at Vits shaft may be removed at will from the carriage. i Suitable sleeves 28 between the ends of the laten and the inner sides of the ends of t e carriage prevent endwise motion of v the platen independently of the carriage.
From the described construction; of the carriage -supporting f and carriage shifting mechanism and also the type-bar supports 3 and 4 it results that the platen is shifted. from lower-case to upper-case position in a direction which is parallel .or substantially parallel to the planes of the type-bar su ports 3 and 4. As will hereinafter more ful y ap ear, this direction of shift is parallel or s u stantially parallel to the plane of the faces of the two types on a type-bar when the ty es are at the impression-point, or, in ot er words, one of the platen and type-bar sup- 3.
port-members is constructed an arranged to shift obliquely in a plane coincident with or parallel to the oblique plane in which the type-bar pivots are situated.
The carriage is provided witha rackbar .29, extending lengthwise thereof and with its plane at an angle to the vertical, as indicated at Fig. 2. The rack 29 meshes with a broad pinion 30, fast on a shaft 31, which is jourvnaled inffthe bearin 10 aforesaid andis rovided vat its. rear en with'a ratchet-whee ,32. A Said ratchet-wheel may be loose upon the shaft and becofnnected therewith by means i of a pawl and ratchet in a well-known man? "ner, Feed and holding dogs 33 34, respectively, on a rocking dog-carrier arm 35 coact with the ratchet-wheel 32 in a known manner to govern the motions of the carriage. The arm 35 is carried by a rocker or shaft 36, journaled under the top of the basel, and the shaft is rocked or turned in one direction by a spring 37, fast at one endl to the shaft and bearing at its other end under the top of base 1 in suchwise that the arm 35 is moved rearwardly whenever the said spring 37 is per' mitted to rock the shaft The carriage is moved toward the lleft .by means of a spring` drum 38 and a strap 39, connecting the drum with an arm 40 on the carriage.
41 indicates `horizontal key-levers 'provided with iinger-pieces 42; 43,fa rod at the rear of the machine and secured to the base 1f' and against .which the key-levers bear by means of notches 44 in theirupper edges 45, s iral springs attached at their lower ends to the levers 41 and at their upper ends to bent ysienne' sembles a comb. v Theupward motion of i ne key-levers 41 is limitedby the bar 43 and a buffer or stop-bar 50 under the cross-bar 7 aforesaid. Each key-lever 41 is provided with an overhanging extension 51, which engages with the upper side of a universal bar 52, the distance between the Loverhang and the key-lever being such that the universal bar may be moved by any one overhang to the extent dueto the full depression of the corresponding key-lever without coming in contact with the top of any key-lever or-` the part connecting with fthe overhang 51. The universal bar 52 is connected with the shaft 43 by means ofarms 53 and jaws 54,'secured to the arms 53'by screws 55. Anupwardlypro'ecting arm 56 is attached to the univer- Sal ar and is pivotally connected at 57 with a forwardly and downwardly extending armfrcnt of rocker-'arm 35 aforesaid. 4
58, Which'is pivoted to a projection on the The type-bar hangers herein shown 'each I' comprise two parallel connected arms 59 and two parallel downward extensions 59a.. The
`hangers are secured to the supportsS and 4 by screws 60, which pass between `the arms 59 and enter threaded lioles in said supports, -V
the flat heads of the screws orgwashers thereunder bearing upon the top edges ofthe arms. Each hanger is provided at or near thebend thereof with appropriate hearings v61 for the coned arbors 62 of type-bars 63: The pivotal points ofthetype-bars 63 are in front of and below the levelgof the printing-point on the.
platen and the type-'bars'innormal positions flare upwardly and outwardly of the machine.
The arms 59 of the type-bar hanger may bev 'adjusted relatively -to each other, so as to' regulate the pressure 4of the bearings 61 IIO against thepivots 62 in any suitable Anf1anner," as by screws 64, which pass freely through the hole in onearm and engage a threaded hole in the other arm in a wellknown manner. angle of. each type-bar hangen'whicli is secured to the support 3, points. upwardly and its arms 59 project u wardly and rearwardly from the support an the extensions59 project vdownwardl and rearwardly, whilethe As shown in the drawings, 'the bend or ,j
point or angle o `each type-bar-hanger which is secured to the' support 4 points forwardly of the machineand thearms 59 thereof project frontwardly Iand, downwardly from the v support 4 and' VtheY extensions 59a project rearwardly and downwardly.4 In both cases the type-bar hangers are arranged radially with respect to the printing-point.
with a type-block 65, having two type or The type-bars 63` are preferably each .providedf' characters thereon, and each type-bar is provided'wi th a circular rack or toothed geared segment 66, and the arbor or axisl of motion 62 of the` type-'bar is eccentrically placed with respect to said gear or segment. The type-bar hangers are provided near the free ends of the extension 59a with bearings 67 for the coned arbors 68 of bell-levers 69.;
vOne arm 69a of each bell-lever 69 is provided with a curved rack-segment 70, and the arbor 68 is eccentric with respect to the center of the said segment 70. The eccentric gearing 66z-and 70, connecting the arm 69awith the lever,` 63, is soarranged that when thetype-baris in normal position'(s'eeFig. 2)' theleverage upon 'the type-bar is greatest and so that when the type-bar is in position in which its type impacts upon the platen the leverage upon the t Ype-bar is least. 4
Preferably the re ative radii of the gears66 and 70 are such that the type-bar swings through an angle nearly three times as-great as that through which the bell-lever swings,
though of course these proportionsfmay be varied to suit different cases or as may be desired. The arms 69b of the bell-levers 69 reject forwardly of the machine, (the keyevers 41 being pivoted 'at the rear of the Inachine,) but are radial with respect to the printing-point and are provided with two perforations 71 72. Connecting-rods 73 are ypivotally connected with arms 69b by means of said perforations 71 (or 72) and withv the key-levers 41. The type-bars normally lie against a padded sup ort 74 l,
The o eration oft 1e t pe-bar movement is as folows: Upon the dnpression of a key 42l the corres ending lever 41 is moveddownwardlyand t e arm 69b of the corresponding lbell-lever is pulled downwardly by the connecting-rod 73.` The upwardlyextending 'arm 69a of the bell-lever is moved forwardly of fthe machine, acting at that time with the maximum' of leverage upon the gear 66 and type-bar 63, thus securing an easy start, of e type-bar toward the rinting-point, and as the motion of the bel -lever is continued thespeed of the type-bar is lcontinually invcreased y(even though the 4bell-levershould continue to ,move ata uniformspeed) yuntil such `time as theJtype-bar strikes the laten, at which momentthe type-bar reac es its maximum speed.. On the release of the depressed key-lever the correspondingspring 45 raises the key-lever,and the 'lever' through the connecting-rod 73 reverses the direction of motion of the-bell-lever 69, land the belllever through the described gearing moves the type-bar away from the platen quickly. During .the vdepression of akey-lever 41 the universal lar 52 is drawn down. and the'arm 35 is drawn forward by the described connections -with the universalbar, thus bringing thev holding-dog341into engagement. with the escape-wheel 32.
,0n the release of the 'key the arm 35 is moved rearwardly by the spring 37 to bring the feed-dog into engagement with the ratchet-wheel 32, and the carriage is moved forward one letter-s ace distance by the spring-drum in the usualpmanner. Upon thedepression of' the upper-case key the tracks 11 and 11a are shifted from the position shown in Fig. 2 to that shown in Fig. 3 and the platen is moved in a direction parallel or substantially parallel to the plane of faces of the two types on the type-bar when the types are at the impression-point. The rack 29 remains in mesh with the gear 30, but slides axially of the gear to a position differ'- ent from that shown in Fig. 2.
It is observed that the type-bar is not upon a dead-center in any position in which it is moved by the toothed gearing described and that since the action of the gearing 66 and'7() is in the plane of the type-bar there is little or no side strain on the type-bars.- By the provision of the eccentric gearing for operating the type-bars it is possible not only to move the type-bars through greater angles even than ninety degrees, but also to get them to flare upwardly and outwardly of the machine to such an extent that the o erator when sitting innatural position, or t atassumed foroperating the keysof the machine, may see the entire line, of print upon the platen Without moving from such position. The line of print is upon the front and upper side of the platen in better view than 1f on top of the platen or at its front, it being assumed that the ribbon is automatically or otherwise removed from over the rintingpoint for the purpose of affording a c ear view of the written line. It is also observed that IOO since the arms 59 of the type-bar hanger are y parallel and that since the extensions 59a and arms 59 are at right angles to each other a 1 single screw 64 suffices for adjusting the pressures of the armsiand'extepsio'ns upon the pivots ofthe type-bar and of the bell-lever.
The rearward shiftin -movement of the platen-carrier 19 may be imited by set-screws 77, which enga e threaded holes in lu s or ears on the brac ets 2 and against whic the links 12`may contact or strike, while the normal osition ofthe platen-carrier may be dene by similar set-screws 78, en aging'with threadedholesin lugs'or ears on t e brackets 2 and contacting with links orl arms 12.
It will be observed that the machine contains a series of pivotedhorizontally-disposed ky-levers extending under an endwise-mova a laten mounted' on the'carriage and movab e transversely to the line of'travel thereof and obliquely to the horizontal plane of the machine, mechanism for moving ythe platen transversely at Will,a seriesof t e-bars pive carriage and tothe front ofthe machine,
oted in `nront. of the platen fan" below the` horizontal plane thereof or belowthe yhorizontal plane of its underside, and that said rails or tracks 1 1 and 11a, to each ofwhich,
type-bars are normally inclined away-fron. the platen toward the front of .the machine and provided with a pluralityof characters the"` laten-frame is inde endently hinged, ares `iftable .together obllquel other; The platen-frame returns to normal position-by gravity. The horizontal key-levers 41rare'r of the secondorder and extend side'by sid'ef'rearwardly from the keyboard beneath the'platen-frame and the type-oper# ating levers 63 Aand 69.4 VEach set of said type-operatingv levers ispivoted in an ob'- hquely-disposed arc or' segment. vThelinks 73 extend downwardly-and rearwardl fron the type-operating levers 69 to the `eyle` vers and'diver e or fan out at their lower ends because o? the latter taking up v"more room widthwise of the machine 'than the type-operating levers.
Furthermore, itA will be seen that eachrigid or sin le-piecevty e-'bar swings -on a sin le pivota centeran that the types are rigidly secured thereto andl face rearwardly When the bar isin the normal position.v
