TYPEJJBITING MACHINE.

' To all whom it may concern citizen of; the United States, residing in Brooklyn, in the county of Kings and State of New York haveinvented certain new .and useful Improvements in Type-Writing Machines, of which the following is a speci- 'ficatiom' 3 English-language.

- or'more characters, which has recently been devisedjfor this purpose bycertain aut'horir' ties. [The lettersfor characters forming this alphabet are not herein 'illustrated,because the machine -is also 'adaptedfor writing other 'languagesthan Ghinese-f The machine Provision is also made for moving is illustrated; as'adapted for writing a single case, both capitals and small 1e'tters;:no case shiftin'g' meclianis'mbeinglshown.' f

It is customary in writing ordinary Chinese characters to place'themone' below another, beginning at the top of the. page, the line of writing reads down the page; and this plan will be continued in connection with the new Chinese alphabet referred to.

This invention provides for the Worksheet to be moved vertically at the operation of the type-l(eys, so that the alphabet characters will beivrit'ten onthe work-sheet one below another, the top of each letter or alphabet character being adjacent to the bottom of the next letter or alphabet character,

in contradistinction to theiisual' method of writing letters side by side as in English. the 'work sheet laterally for making spaces between the vertical lines of writing. According to the Chinese custom, the writing begins at the right-hand inarginof the \vork-she'gt and proceeds line-byline toward the left hand margin. 7 v

In carrying out the invention in its present form,.the worksheet is placed upona revoluble cylindrical-platen, which extends in a direction at right angles to the line of writing; and at the successii-"c type he strokes, the platen is caused-t0 rotate to ad for alphabets not provided ,withso that showing a part ofthetrainlof gearsiwhi controls the rotation of the platen, and a showing a release key for said carriage.

'vancethe sheet so that theoperation of 'the keys causes the line of print to proceed from the top to the-bottom of the sheet. 1"]? Preferably a. spring jisjemployed to r0 tate the platen-for this purpose, and -an es" I ca pement or letter-feeding meehani'sin Loon-'- trols the rotation otth'e plateneifected means of said spring. 1- Upon the conclusion of a line of writing, arhandle is drawn down 7 for the purpose of rotating the-platen-ba-ek I to initial position for beginning. anew line of writing and at the same time, the platenrotating spring is re-wound.

The platen is preferablymounted iipona left toright to make. the spaces between carriage which is moved; step bys t p from the'lines; and this line-feeding mechanism is preferably-operated by the .sa- 'ne halndle which rotates the platen backwardly to'begin anew line of writing, so that immediately-.'

after said handle is operated,- the writing-oi jthesucceeding line may be'begum Ais'epa rate key is also provided for line-spaeiilg the platen whenever desired.-

which ermitsthe line-spacingmovementof the platen carriage without disconnecting the platen from its driving springgo'rfrom its escapement mechanism.

Other features" and advantages inafter appear.

In the accompanying drawing s, Figure is a side elevation of the platencarria 2 is a front view of a spring-barrel which rotates the platen and an escapeinent wheel which is fast to said barrel;. this figure also. showing the type keyecontrolled -dogs which embodying the present improvements. Fig. I 4 is a detail sectional elcvationof devices for automaticall line-feeding the carriage during the backward revolution of the platen to begin a newline of writing. Fig. 5 is a rear perspective view of a train of gearing which controls the letter-feeding rotat-ion of. the platen. Fig. 6 is a side elevation of some of the members seen in Figs. .4 and 5. Fig, 7 is a perspective view of the line-feeding dogs,' showing particularly a [cutaway 83 in the ribbon-controllinguni-' .ve'rsarl bar. frame which isoperatedby the type-keys, and which by reason of said outrear part of the machine.

The drawings show anUnderwood frontstrike typewriter', which is used for con-- .venience in illustrating the. invention; said typewriter being however substantially away is prevented from operating said linefeeding dog's. Fig. 8 is a plan of the typeoperating keys and levers, and some ofthe' gears w'hich'control the operation of the platen.

Fig. 9 is a rear elevation of the modified for the purposes of the invention.

Alphabet keys 1 are mounted upon levers 2, fulcrumed at 3 and having returning springs 4; the levers having in-andsslot connections at 5 with bell cm s 6, which have pin-and-slot connections at 7 with type bars-8,- carrying alphabet types 9 to swing upwardly and rearwardly to strike upon the frontside of arevoluble platen 10; the type bars being mounted upon a' curved fulcrum rod 11: The types '9 are intended for writinga foreign language, and correspond with foreign alphabet characters or letters on keys 1, which areillu'strated diagrammatically at: Fig. 8. Theplaten is not made to shift up and down, the machine being intended for-use in writing foreign-languages which donot have sets of both capital let- 'ters and lower-case letters; but the invention is not limited to the, use of a single case of types.

The types strike through a ribbon 12, h

which is normally below the printingv point, but which is lifted up at every type stroke to cover the printing point; there being' for this purpose heels'13 provlded on the type bars to engage a segmental universal bar 14, which forms'part of a frame 15, that is moun'tedto' be driven rearwardly by theheels 13 on the type bars 8; said universal bar at its rear end having arms 16 pivoted to the upper ends of upstanding arms 17, which are fast to'a rock shaft 18;

-- the front of the universal bar frame 15 being supported in the usual manner, and

. a spring 19 returning the universal; bar

frame 15 after actuation. Upon this universalbar frame 15 is fixed a slotted actuator 20 to engage a pin 21 upon the ribbon vibrating lever 22, which is pivoted at 23 upon the machine frame; said lever 22 carryi'ng at its forward end an upright slide 24 to' which is threaded the ribbon 12; for as the universal bar is driven back the slide or vibrator 24 is thrown up' together with the ribbon, and hence the types make inked impressions .upon the Work sheet 25 which is carried around the platen 10.

As each character is printed, the paper is fed up, the platen 10 being revolved step-- by-step for-this purpose. This rotary letter or character spacing movement of the I which extends a rock Shaft 32- fast thereto; 0 4

the rocker-31 being confined between ears 33, 34 fixed upon theframe work and seiving as bearings .for the rock shaft 32. This shaft is elongated and at its ends is journaled in bearings 35, 36; and it has at its ends a forwardly extendingpair of arms 37, which are connected at their forward ends by a rod 38,, which forms a second universalba'r, and is pressed by a' spring- 39 up against the under sides of the key levers 2. g I

l/Vhenever any key is depressed to operate its type, the universal bar 38 is depressed, and the dogs 29, 3Q are vibrated-forwardly;

the escapement wheel 28' not beingl'et off 9 at. this time, but the limber dog 29 being drawn to the right at Fig.9 by means of a spring 40, so as to be in position to engage the next tooth of the escapement Wheel 28.

Uponthe release of the key from pressure 0 after the type impression is made, the spring 39 returns the universal bar 38 and the dogs 29, 30permitting the escapement wheel 28 to advance one step and the spring 26 to rotate or drive the platen a corre- 5 sponding distance. I

The train of gearing between t. spring I barrel 27 and the platen may comprise a bevel gear 41' fixed onthe spring barrel,

a bevel pinion '42 in mesh therewith .and 11a.

mountedupon avertical shaft 43, a-bevel pinion 44 on the upper end of said shaft,- a bevel pinion 45 fixed on a horizontal shaft 46 which is journaled in the machine frame,l

and a gear 47 fixed upon shaft 46 and meshing with-a long barrel pinion 48 which is journaled by means of gudgeons 50 upon brackets 49 fixed upon the machine frame.

This barrel pinion 48 may engage either of two pinions 51,52, both of which are fast 12o upon a horizontal shaft 53 extending from end to end ofthe platen frame or carriage 54. By means of intermediate pinions 55, 56, the pinions 51, 52 are connected to pinions 57 ,58, fixed upon the axle 59 of the platen 10, and forming part of the gear train leading from the spring. barrel 27. The platen frame orcarriage 54' is mounted to move endwise for linespacing; and x' 'hen either pinion 51 or 52 moves out of mesh aspring 26" ('Fig'.

with thei barrel pinion 48, the other pinion always remains in mesh with pinion 48, so that'a positive connection is maintained be- "tween the platen and the spring barrel 27 and its escapement devices, and hence the writing, the operator grasps a'handle 63',

pivoted at 64 on the right-hand side of the machine frame, and throws the same downwardly from the dotted-line-position at Fig. 3 to the full-lineposition at Fig. 5, thereby both rewinding the spring 26 and revolving the platen 10 backwardly to initial position;

the limber dog 29 beingswiveled at x 65 (Fig. 2) in a] manner common in type- 7 writing machine s,- to permit the backward revolution of the letter-feeding escapement wheel 28. The-handle or arm 63 is con nected tothe spring barrel 27 by means of a sector166, extending rearwardly from the pivot 64, and meshing with a bevel pinion G7, to which is fixed a pinion 68, meshing with a gear 69 on the spring barrel 27.

It will be seen that the. foregoing alphabet character or letter-feeding mechanism is effective to rotate the platen at every key stroke, regardless of the position of the platen carriage,.so that the writing of vertical lines on the work-sheet may proceed until the: same is filled.

A non-printing word-spacing key or bar 70*,inay be arranged across the machine in front of the keyboard, and its levers or supports 7O may extend back parallel with the type-key levers,.and actuate the umversal'bar 38 at every depression of key 70*; and these levers 70 may, if desired, be curved at 7 0 'to clear the bell cranks 6.

After the completion of any vertical line of writing, a key 71 may be pressed back for line-feeding the carriage 54, which slides upon horizontal rails 72, 73 in the same manner as the paper carriage of said Underwood typewriting machine. This key 71 permits the carriage to be drawn along by a spring barrel 74 (Fig. 9), which is connected by a strap 7 5 to a pm 76 on the carriage; said strap passing over a pulley 77 and forming a return loop, so that the spring barrel 74 draws the carriage from right to left, as seen at Fig. 9. \VllK'll lS a rear view. V'ewed from the froat of the mach ne, the carriage is drawn from left to right at the line-spacing opendimi. This is useful for languages like Chinese and others, where the first vertical line of writing is made at the right-ham? side of the work-sheet or page, and in which "the second line of vertical writing is placed at the left of the first 'line of writing, and so on until the page is filled. 1

A rack 78 is connected to the carriage to mesh with a pinion 79, to which is connected an escapement wheel 80, which is controlled by dogs 81, 82, which may be constructed and operated in a manner to resemble the letter-feeding dogs of said Underwood tyilewritin-g .machine, with the exception that they are not operated by the letterfeeding mechanism of the present machine; the universal bar frame 15 being cut-away as at 83' (Fig. 7) to avoid striking these dogs 81,82. p At the completion of a page of writing, the carriagemay be pressed back to the left,

th'us rewindin'g the spring barrel 74; the

escapement wheel being connected to the pinion 79 by means of pawls 84 (as usual in the letter-feeding mechanism of said Underwood machine) to permit right to left movement of the carriage while the escapement wheel 80'remains stationary.

, The carriage may be released to be set to different line positions, by depressing a release key 85.0n the carriage, which is connected' to a bail 86 pivoted at; 87 on the carriage and having thereon the line-feeding rack 78, which by depression of the key is lifted from the pinion 79. Said linefeeding key 71 may be mounted on the forward end of a stem 88, to press rearwardly a lever 89, the latterpivoted at 90 upon the framework, and at its lower end connected to a link 91, whichextends rearwardly to an arm 92 pendent from a horizontal rock shaft 93. At its inner end said rock shaft carries an-upstanding arm 94, which, when the key 71 is pressed back, engagesthe feeding pawl or dog 82 to press the latter and the pawl or dog 81 rearwardly; and upon release of said key 71, a spring 95 returns the same,

and a spring 96 returns the dogs 81 and 82 I to normal position, thus permitting the escapenient wheel 80'to feed one step, together with the platen carriage 54. and thus effect a line-feeding movement of the work sheet 25. By manipulating said key 71, the open ator may make as many spaces as desired between the vertical lines of writing; or the carriage-release key may be used for the same purpose. Also depending from the rock shaft 93 is an arm 97, seen best at Fig. 4, which is provided for enabling the platenrotating arm or handle (33 to effect automatically a line-feeding movement of the platen carriage. Said arm 03, for this purpose. is fast upon a horizontal rock shaft 98, which at its inner and carries an arm or dog 99, to engage a pawl or trip 100, which is pivoted at 101 upon the lower end of said arm 97, and is normally held by a s .)ri-n g 102 against a stop 103 on said arm 97; the pawl having a shoulder 104 to engage said gages and drives the pawl 100 and the arm 97 bodily forward; these parts turning about the shaft 93 as if they were made in v one piece, and causing the arm 94 on said shaft to swing rearwardly to operate the line-feeding dogs 81, 82.

Preferably, before the conclusion of the 'down or driving stroke of the arm 68, the

point of the dog 99 escapes from the pawl 100, so that at any time thereafter the key 71 may be operated to perform its line-feeding function wholly independently of the said dog 99 or of the arm 63; the latter, of course, remaining in itsdepressed position until the types are again operated andthe .platen rotated for letter-feeding; said arm 63 gradually rising during the writing of the next vertical line on the work sheet.

During the return stroke of the arm 63 and the dog 99, the dog engages and idly rotates the pawl 100 about the pivot 101; and after the dog passes the pawl, the latter is snapped back to normal position by its spring 102.

Certain of the type keys, as for instance key 1, are silent, that is, they are capable of printing but incapable of causing the work-sheet to be character or letter-spaced, these keys being used for accenting or for building up alphabet characters, or for other purposes. The lever of each such silent key 7 is arched upwardly at 70, Fig. 3, to clear the second universal bar 38, so that said key lever cannot operate the alphabet character or letter-feeding dogs 29, 30. Its type bar, however, is provided with the usual heel 13 to operate the first universal bar 14 which controls the ribbon-vibrating mechanism, so that the ribbon is thrown up to cover the printing point although the paper is not fed.

Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my, invention, I claim:
