uiuTEo stares EDY/JARD BERNARD HSS AND LEX/VIS CARY MYERS, 'OF
ASSIGNORS TO ROYAL TYPEWRITER CQMPANY, HIC., 0F NEW?" BRO To all whom t may concer/n Be it known that we, EDWARD BERNARD Huss and Lnwis CARY MYERS, both citizens of the United States, residing in Brooklyn, county oi Kings, city and State of New York, have invented certain new and useful improvements in Typewriting Machines, of which the following is a specification.
The application for this patent is a division of our application for patent tiled Jan nary 13, 1921 No. $6,924. That application shows al1 the mechanism of a complete typewriting machine. The invention claimed herein relates particularly to a novel ar rangement of certain parts of the mecha? nism oi' the typewriting machine whereby it is simplied and made small, compact, light and portable, but strong and durable, and whereby writing in such small machine may beat all times plainly visible.
ln carrying out our invention we employ 'sheet metal and drawn stock to a very large extent in the construction of thelmachine, in order to make the mechanism both strong and durable, as well as light and' compact. lNe use the full number ot' keys in the key board, arranged in four banks, as in most standard machines. Efficient mechanism is provided for shifting and locking the platen for upper and lower case printing.
lnasmuch as the height of the new ma-y chine is considerably less than that of the standard Royal machinedthe printing point on the platen has been placed considerably above a horizontal line drawn through the axis of the platen and the ytype segment has been inclined rearwardly and 'arranged' obliquely with reference to the horizontal plane et the machine in order that the line ot print may be properly presented to the eyes or' the operator. This involves a new arrangement of the mechanism for connecting the key levers to the type bars in order 1 K v ,typewr1ting machine with our impr that the latter may be properly moved from their points of rest to the printing point.
As in the Royal machine, we employ a unitary platen carriage. systemv and the gnfncral construction of the margin rail, center stop, estapement and ribbon driving mechanism is similar, but the arrangement el' some oi these mechanisms has been some- Specicaton of 'Jetters atent,
movementot the carriage. Thus what changedE mounted and actuated plane oblique to the hm key levers, and the type in a tan-shaped field, i. theinner ends of the type is considerably smaller t which the 't e carryin, hars are disposed wher The contraction and mechanism in the new' nu; all interference of one part the transmission of power keys to the type bars, which is though a diiiicult feature in a cor able full-standard key board avoided,
rllhe key levers are Conner bars by flexing connectit a tensile strain on the type b them to the printing' poiY tu' or accelerated velocity as they ap printing point. These connections i i en the type bars and the key levers are made 75 between the linger pieces wherl power is applied and the fulcra of the il said levers are provided with eater is projecting rearwardly from the iunioru which engage a universal bar that eo uls the 80 ke Y levers when acting upon the un'.y bai arel of the first order and when ac'I type bar mechanism are oi `the seco o, order.
inasmuch as the type bars in the ner' chine are operated by tensile et tween the key lovers and the as these connections are way, the machine is not inn tion as is the ease in machines at sion and lateral strain ai. A connections.

Figure 12 is a detail sectional view of the bracket which supports the worm shaft of the ribbon mechanism and some ot the stops for limiting the vertical movements of the carriage.
The base frame A ofthe machine is made of a thin, light but stout and strong sheet metal. Separate front' top plates A2 are employed and they are secured in place at a5. The frame serves as a base support for all of the mechanism and a casing for portions thereof. The top plates A2 serve as a dust shed for parts of the mechanism.
The segment B to which the type bars C are pivoted is of cast metal and it may be here stated that this member is the only one in the machine which is cast, all other parts being of the lightest possible character. This part is made particularly strong and rigid inasmuch as it sustains a large number of type bars which must be pivotallv mounted in such manner as to be moved with the greatest accuracy and precision toward and from the printing point on the platen. The segment serves to support other parts of the mechanism as will be hereinafter described.
It will be observed that the segment is arranged at an oblique angle to the horizontal, this angle being obtuse to the plane of the key levers, as indicated in Figure 8. rThe segment is formed with a curved rib b which provides a striking surface for the type bars intermediate their ends and en'- sures' the impact of' the type at the proper point withoutundue penetration of the material to be printed upon.
The type bars C are thin, light and strong,
being made of sheet metal, preferably corrugated as indicated at c. rIheir inner ends are disposed in slots b cut in the lower portion'of the segment and they are pivoted to a curved rod or wire b2 at the inner end of the slots. V
The type carrying ends of the type bars rest on a support C" suitably cushioned and so ldisposed asnto normally hold the type bars atan obtuse angle to the plane of the segment, but in this case the arc of the support is materially greater than that of the inner -bearing points of the segment. In this way the pivoted ends of the bars may be brought clse together while the outer ends thereof may be spread so that the type carrying ends ot the bars may not interfere. In this way also space is provided in the neighborhood of the segment for accommodating certain parts of the mechanism.
' It will be observed that the front part of sheds A2 and in front of the support C is closed by a bridge piece A3 which is attached to the front plates in the manner indicated at al". The u per part of this bridge piece is curved in tie manner shown and it has a downwardly extending portion a (Fig. 3) which reaches to the type bar support H and covers the mechanism immediately in rear of it. In this way the dust plates A2 and the bridge piece A3 serve to protect to a very large extent parts of the mechanism. It will be observed that the type heads are covered by the bridge piece A3 and furthermore that the curved middle portion of this bridge piece is below the top plates A2 so that the platen and parts immediately below it are distinctly visible.
It will be also observed that while the mechanism in the rear part of the machine is obliquely arranged, the parts in the 'front of the machine, excepting the type bars, are shown arranged horizontally. The top plates A2 are arrangedin a true horizontal plane and the ribbon spools R whose shafts extend through the plates A2 are arranged horizontally somewhat below the line ot print and they lie above the top plates or dust sheds A2.
The type bars C are normally-held on their rest or are returned thereto by individual lsprings c2 attached to a flange c3 of the rest and to the type bars near their inner ends in front of and above their pivots.
The key board contains the standard number of type keys, viz, forty-two` arranged in four rows or banks and it lalso contains keys K, K', K2 for' operating the carriage shift, back space and margin release mechanism. Each of the forty-two key levers E is of the first order fulcrumed on a common Arod e, `its front portion being connected to a type bar'between-the tulcrum and the finger piece while the rear part of the levbr is extended rearwardly from the fulcrumand operates on a universal bar F. Each key lever, therefore, when operating on the universal bar is of the rst order, but when operating a type 'bar it is of the second order, inasmuch asl at this time the weight is situated between the lever and the fulcrum.
nimeer.
-g to the rear ends ot' the short bent links (fr pivotally mounted on a coini'non rod gf which is supported in a frame H. Each link (it is connected by a link g2 to a corresponding key lever E. ln order that the levers G may be placed close together to economize space. the links are connected with the levers at different distances troni their pivots, as shown in Figure 3.v
The rear ends of the key levers move diierent distances, inasmuch as the levers are of different lengths. Therefore the rear ends ot' these levers are inclined at dilerent angles and in such manner as to give to the universal bar the same movement whichever key is operated.
The means described for connecting the key levers to the type bars afords a HeX- ing connection between these members and a tensile strain is imparted through the links g from the key levers to the 'type bars. Furthermore, the connections are such that the types approach the printing point with an accelerated movement, which is at first comparatively slow when the keys are first touched and they rapidly increase in speed as the depression of the keys continues. lnasmuch as the platen is arranged in an obliquely disposed carriage and the printing point is above the horizontal plane of the axis of the platen, the connections between the key levers and-the type bars are such as to give the required movement to them.
The arrangement of the type bar operat? rear row ot the key board are each connected to one of the longer links 'G by a.
link 1,1 extending upwardly from the cor-A responding key lever, the points ot connectionV ot the link y to the link G and to the key lever being such as to aiford the desired extent of depression of the finger piece a" of the key lever to throw the corresponding type bar to the printing' point. The next longer key levers whose finger pieces .frz are in the second row from the rear in the key board, are also each connected to a link G by a link i/Z but the point of connection of the latter link to the link G is nearer the fixed axis about which thelink (i moves ythe same touch.
are each connected to one of the shorter.
lront links tl as shown .in Figure 3 by a link gf?. .lfhe distances trom the axes ot these shorter links (i and from the aires of the corresponifling key levers at which the connections ot' the vertical links are made are such astio atlord a depth of depression ot the finger pieces, the same as that tor the finger pieces ir', in the two rear rows and also ot substantially 'the same touch.
Each lever carrying a finger piece ai* in the :trent row ot' the key board is connected to one ci the shorter front links by a vertical link je/ The connection ot the latter link to the front. link G is nearer the fixed axis thereotl than is the connection between the key levers ot the third row and such axis. The finger pieces al* of the lower row in the key board have the same extent of depression as the others and'substantially As the front links G are made alternately long and short, the staggering of the ends of the links with reference to a straight, transverse lineaitords ample room 'for the hooks, by which the links g and y', y2, fy, y* are attached to the links G so that in the operation of the machine one cannot interfere or collide with another. Each front link G is of elbow shape, its lower front end being bent upwards. The point of connection of the t pe bar link g to the corresponding link (z is thus made at a higher point than heretofore. In this way we are enabled to reduce to some extent the height of the machine and parts ot' the mechanism are made to so co-operate to effect the full throw of the type bars. Furthermore, the requisite clearances are obtainedbetween moving and stationary parts Y The platen Z is mounted in a carriage, the side pieces l) ot which are shown in the drawing. These sides are connected by' a sheet metal rail Z supported lby a sheet metal carriage shift rail L having downwardly extending legs Z (Figure il), the lower ends ot' which are pivotally connected with the trout ends ot links Z2, the rear ends oi3 which are pivotally connected with the sides of' the base trame of the machine. The tront ends ot' the carriage lifting levers L2 are pivotally connected with the shift rail at 2*. while the rear ends ot these levers are' secured to a rock shat't Z kmounted to turn in the, machine traine.
lt will be observed that'thc carriage traine is arranged obliducly. 'lille rails li have their opposite surfaces rearwardly and downwardly inclined at a slightangle and in order to adjust this angle, ,the pivots of the links Z2 are made adjustable as indi cated in F ig. 8. As there shown, each link Z2 is connected by.a screw Z6 to a sleeve or spacer Z7 and is free to turn thereon. The spacer extends through a slot Z8 in the side of the frame A and has a iattened portion Z9 therein. The spacer carries a nut Z1 between which and ythe sides of the frame a washer l is interposed. Each of the links Z2 is mounted in this way and by these devices the inclination of the carriage may be adjusted. The rock shaft Zcarries a rearwardly extending arm m connected with a vertically arranged coiled spring m, attached to the lower portion of the base frame and which serves to, in a measure, counterbalance the weight of the carriage and to assist in elevating it. By the de- -vices described, the carriage may be given adjustments by which the printing point ot' the platen may be slightly varied in order that the type bars may properly abut the ridge I) on the segment and that the type may strike the platen at the proper point and with suitable force.
There are anti-friction ball bearings in-v terposed between the railsl and L of the kind commonly used in the Roya-l machine and the rails Z, L are held properly connected by guiding plates m2. The rails Z, L are made of light but'tough and strong sheet metal, bent to the required shape.
In order to Jfurther support and guide the carriage, we provide a guide bar M5 which is secured to the sides of the base frame in a machine and this bar (3o-operates with a roller m3 and a pinmtcarried by an arm mi projecting upwardly and forwardly from the :trame N of the escapement mechanism.
In order to shift the platen carriage for upper and lower case printing, we employ a shift key K pivoted at 0 (Fig. 6) to a frame il in which the key levers are arranged. rPhe lever K has an upwardly projecting arm o5 connected by a link o to the lower end ofan arm o2 extending downwardly from one of the lifting levers L2. The link 0 is provided with adjusting devices 03 by means oi which its length may be changed and its front end is formed with a loop o4l which engages a pin o on the lever in order that the lever may have a slight movement before moving the rod and the lifting lever L2 connected therewith. By
depressing the nger piece K, the lever may he operated to elevate the carriage for up per case printing and hold it as long as the finger of the operator is held ou. 'the key. YVhen it is desired to hold the carriage in an elevated position tor printing a plurality ot' capitals. a lever tl may be depressed which serves to lock the carriage sluit key.
T he mechanism shown at O2 for 'thus locking the shift key is of'well known construction and need notbe described in detail. Suffice it to say that when this key is depressed, it holds the carriage in upper case position until the shift key is operated to release it.
In order to lock the carriage 1n lower case position, we employ a latch P (Fig. 6)
in the form of a vbell crank lever of general L-shape. Itis pivotally mounted at p and its upper end Vcarries an arm p which engages an ear Z15 which projects forwardly from one 'of the legs Z of the carriage sup-.
port. 'The rlatch P is normally inclined from its lower end upwardly and rearwardly andfthis upward, rearwardly extending portion of thelever is connected with a spring p2 attached -to the base frame.
The latch P is connectedfby'a link p3 with the upper end of thearmfo5 of the lever K and when the shift leverfi's operated, the f latch .P is first released from the carriage and then the shift lever serves to` raise the carriage to the desired extent. It will be observed that the link p3 isl connected to the latch in rear of its pivot-and when the shift key is operated, the latch is turned quickly to release the carriage and before the shift key can operate. Furthermore, it: will be seen that the latchl is so located and mounted that its upper front portion does not at any time come in contact with the frame J in front of it. The. lower portion of thelevcr K isy provided with an extension 01 which drum- Q housed in a suitable casing. The
spring'drum is carried by an armg on av bracket Q4 secured to the left-hand side of the base frame and this bracket serves to support parts of the ribbon operating mechanism.,
1n order to control the transverse movement of the carriage, appropriate escape ment mechanism is provided. T indicates a rack bar supported on arms t pivoted to the side platespf the carriage at t. As the mechanism for releasing the rack banfrom its operating pinion forms no part of the present invention, the detail of this mechanism is not illustrated. The plinion- S with which'the rack bar T engages is connected with a ratchet wheel S controlled by escapement mechanism indicated at U, (Fig. 5) but inasmuch as this mechanism is similar to that in the standard Royal machine, it is not shown indetail and need not be further described except to say that by reference particularly to Figure 5 it will be observed that the escapement mechanism is obliquely arranged in' a manner similar to the arrangement of the type barsegment and the carriage release. t may be said, however, that the escapement rocker u is pivotally mounted in a frame N. The rocker is oper.- ated by a lever T2 pivoted at t5 to an arm t extending forwardly from a bar A 'secured to the middle portion of the rear part of the machine frame. The lever T2 engages a roller t7 on a downwardly extending spring arm t1 ot' `the rocker. As `the lever T2 is oscillated, the rocker is correspcndingly moved and operates the escapement mechanism.
The lever T2 is operated by an arm f projecting from the universal bar F. The arm f of the universal bar is connected with lthe lever T2 by a link ft, the length of which may be varied byV the devices f5. 1t will be observed that the universal bar is arranged horizontally or nearly so instead of vertically as in many prior constructions. In this way it is adapted to a frame of small height or size and it is also adapted to be operated directly by the extensions of the key levers and the space levers. Tt will be observed that the key levers when operating on the universal bar are ot the first order and there is-no mechanism interposed between the key levers and the universal bars. This affords a compact, small and efficientl construction.
it will be observed that the frame N of the escapement mechanism has a bracket a in which is mounted a set screw a. This screw is adapted to engage the top of the flanged rear portion of the base frame when the carriage is returned after being raised. The screw thus acts as a back stop for the carriage, arranged centrally of the machine,l
and this stop co-operates with other stops An2, n4 at the front of the machine. The stops n2, n.3 on the right-hand side of the machine are carried by a bracket fw to which the back space lever is pivoted, while the.
stops n?, 1r of the left-hand side of the machine are carried by the bracket Q4 which supports the spring drum and parts of the ribbon mechanism. By these devices, the oblique movement of the carriage is accurately controlled. The set screws a2, 11.4 arrest the downward.movement of the carriage by engaging the shift rail L while the screws n3, a5 arrest its upward movement,
being arranged to abut against arms fn. on
the downwardly extending legs Z ot the shift rail. Y
An arm N2 extends from -the escapement iframe N and projects downwardly and rearwardly therefrom, its lower end abutting against an adjusting screw N3. This arm is arranged longitudinally of the machine and as shown is formed integrally with the seca-pement trame The arm serves'to steady the carriage and prevent it trom tilting or moving forwardly. It will be understood that the escapement trame N is connected with and supported by the lower shift rail L', as shown in Figure This connection is similar to'that in the Royal standard machine. Inasmuch as the carriage overhangs its front supports and as the carriage is a lloating carriage being supported at the front by the shift rail which is in turn supported by the swinging links and levers, there is-a tendency for the carriage to sag, but by means of the brace arm N2 in co-operation with the front supports of the carriage, this tendency is obviated as by means of the set screw N3, a torsional strain can be imparted to the sub-frame of the carriage which will cause it to maintain itsproper oblique arrangement without any material change. The set screw N3 extends through the back frame and through the tie plate A* as indicated in Fig. 5. In this way we provide what may be termed an aligning arm, which extends from the shift rail or carriage support to a rigid abutment.
The drawings show some of the mechanism ol' the typewriting' machine which is not herein particularly described as it forms no part of the present invention, and some features of which are claimed in other copending applications.
The platen Z, it will be understood, cooperates with the paper table-Z' which may be of any suitable kind. The ribbon R passes'trom spool to spool R around guides r past a type guide R2 and may be suitably guided by a vibrator or other suitable ribbon guide V.
The drawings show, Fig. l, a margin release key'li, but the mechanism connecting this key with the margin release lever is not shown.
Figure l of the drawings also shows a handle K5 for controlling the operation of lthe ribbon mechanism, which mechanism is claimed in another co-pending application, but inasmuch as part of this mechanism is herein shown and inasmuch as part of the vibrator mechanism is also shown, it willi be briefly described.
As shown in Figure 5, the vibrator V extends downwardly rom the type guide and is pivotally connected at 't' with a bell crank lever 7() pivoted at 7l to the escapement iframe N and having a downwardly extending arm 72 pivotally connected at 73 with a downwardly and rearwardly extending arm 7a, having a rear edge provided with two parts T5 and 76 adapted to engage a pin T7 carried by the lever T2, which as before explained is actuated by the universal bar. Each time that the universal. bar is actuated the arm T4 is turned on its pivot 73 and coi'-, respondingly moves the bell` crank lever l() which in turn actuates the vibrator. The
