WRITING-MACHINE.

Application filed September 23, 1918. Serial No. 255,326.

To all whom it may concern.

Be it known that I, ROBERT J. ORR, a citizen of,the United States, residing in the borough of Brooklyn, in the' county of Kings, city and State of New, York, have invented new and usefullmprovements in Writing-Machines, of which the following is a specification.

This invention relates to writing Ina-- chines, and particularly to machines for writing musical notations, and it is the object of the invention to provide a writing sible to write or print not only the notes or characters representative of different tones, but also all of such signs as are commonly used in the different parts of musical oom position:

It is a further object of the invention to provide in a machine of this character a platen to carry the paper upon which the music characters and signs are to be impressed, said "platen being mounted in a carriage to have to and fro longitudinal movement with the necessary mechanism to advance the carriage with the platen step by step letter space distances in the usual manner in typewriting machines, and to adjust or line space the platen at will either forwardly or backwardly predetermined distances equivalent to one or more degrees of the music staff within. a single octave or a multiple of octaves to collect and properly arrange the diiferent parts of a musical composition in the form of a score.

It is another object of the invention to provide in a Writing machine of the present.

commercial type of machine mechanism to line space a platen at will either forwardly or backwardly distances representative of one or more degrees, or multiples thereof, of a music staif, and to substitute for the characters of the i pression making devices representative of written speech characters representative of musical notation.

It is a further object of the invention to provide in a machine ofthis character a paper shelf or table to eatendlongqtudn nally of and above the writlng line of the laten, and means to hold the paper firmly in contact with such shelf to facilitate the characters when sweeping lines are desired,

such as braces, and slurs or lines representatlve of expression as crescendo, diminu-- endo, &c.

It is a still further object'of the invention to provide a templet for use 'in connection with the paper shelf for the manual writing of lines of expression, such as slurs or the like, and other musical signs, in connection with the mechanically written characters.

It is'a further object of the invention to provide an improved lay out for a keyboard for machines for writing musical composition so arranged as to be adapted for writing machines in which the impression making devices carry two characters or Iportions of different characters adapted 1 to e compounded or built up in writing a single music character, and to show the relation of the music characters to the music staff to guide the operator and facilitate operation. 1

Other objects and advantages will hereinv after appear.

While the present invention relates par ticularly to a'machine adapted for the writing of musical composition the invention is applicable to any of the well known commercial typewriting machines utilized for the production of vwritten speech by substituting for the characters representative of written speech impression making devices or characters representative of written music, and as an illustration of an embodiment of the invention the invention has been shown in connection with a typewriting machine of the well known Underwood make, only so much'of the mechanism of snot 'nachine bein shown as is essential to an understandlng of the invention.

Fig. 21 is a plan view of the templet to be used in connection with the paper shelf for manually producing music signs in coning frame at the forward end, as shown at 24, being supported by a roller 25 upon a rail 26. Type carrying bars 27 to strike rearwardly against the front of the platen, as shown in dotted lines in Fig. 1, are fulcrumed upon a wire 28 in slots of a segment 29, and are actuated by levers 30 carrying at their forward upturned ends finger keys 31. A heel 32 on the typeb'ars as they are moved to printing position engages with and moves a universal bar 33, said bar forming a part of and actuating feeding devices (not shown) to advance the platen carriage step by step in letter space direction upon the actuation of the typebars. The typebars each carry two impression making characters, and to position the platen so that the writing line of the platen is in position to receive either of said characters the platen frame is arranged to be capable of assuming an upper and lower position. For this purpose the rail 26 supporting the front portion of the platen frame is fixed at opposite ends to a pair of carriers 35 secured to I a rod 36 fulcrumed at its ends in the ma-.

chine frame F. To move the carrier 35 and thereby shift the rail with the platen to the upper position there are provided two levers 37 the actuation of either one of which levers operates to raise the rail with the carriage. The levers are fulcrumed as at 38 and extend to the front of the key-board and have finger keys 39 at said ends with designations representative of said levers. (Figs. 2 and 3). The rear end of each lever has an arm 40 to engage the rear of the carriers 35 below the carrier supporting rod 36. As the finger key end of said levers is depressed the lever arms 40 are moved forward and the carriers 35 moved to raise or lift the rail and thereby the platen to its upper position. Means are provided to retain the platen shifting mechanism in position with the platen in its upper position, but as such mechanism is well known a detail description and illustration of the same is not deemed necessary.

The paper, shown in a general way at P, to receive the impressions upon the platen from the impression making devices is guided between feed rollers 41, 42 and the -platen and around the platen by a table 43 extending between the ends of the platen frame.

The. foregoing description is of mechanismwhich is common in the Underwood typewriting machine, and while the invention is illustrated and will be described in connection with this type of writing ma chine in which the platen is adapted to assume two different positions, an upper and 1 a lower position, and normally maintained resentative or equivalent of one or more degrees or diatonic sounds above or below the initial note, and in order to meet the re: quirement of modern musical composition the mechanism is adapted to adjust or line space the platen either forwardly or back wardly a single or a multiple of degrees withina single octave or a multiple of octaves thereby enabling the operator to collect and properly arrange the different parts of a musical composition.

. To line space the platen forwardly or backwardly a single or a multiple of diatonic sounds or degrees to raise or lower the tonethere is provided a shaft 45 rotatably supported in two pairs of hangers 46, 46' fixed to the platen shiftrail 26 to extend rearwardly therefrom, and the shaft retained in said hangers by blocks 47 a to engage over the wheel hubs andi'releasably connected to the hangers as by screws passing through erforations in said blocks and threaded into the hangers. The shaft is also journaled at its ends in bearings 48 (Fig.3) secured in the platen frame ends. To rotatably support the shaft in said bearings one end has an integral head 49, and a head 50 in the form of a collar (Fig. 20) is removably secured to the opposite end of the shaft as by screw threading thereto, and locked thereto by a set screw 51 (Fig. 11) thraaded into portions of the collar and the sha t.

The shaft 45 is geared to the platen by gears 52 mounted at opposite ends of the shaft to rotate therewith, and each gear having a hub portion 53 whereby they are journaled in the bearings 48 with the ends of the hubs abutting against the inner sides of the heads 49, 50 of the shaft 45. The gears are retained in the bearings by set screws 54 threaded into and passing through the gear bearings and engaging in annular grooves 55 in the gear hubs (Fig- 4) for a purpose to be hereinafter described. The

gears 52 mesh with pinions 56 having a hub whereby they are journaled in bearings 57 secured in the platen frame ends and held against axial movement by set screws 58 threaded in and passing through saidbearings to engage. in annular grooves 59 in the pinion' hubs. (Fig. 4).. The pinions 56 mesh with teeth formed on heads 60 secured to the ends of the platen.

A pair of toothed or ratchet wheels 60, 61 are mounted on the shaft 45, said wheels having hubs extending from opposite ends and whereby the shaft 45. is journaled in the hangers 46, 46'. The shaft 45 is adapted to participate in the longitudinal to and fro movement of the platen carriage. However, the wheels 60, 61 do not participate in this movement but are mounted on the shaft to rotate therewith. For this purpose the shaft has a flat portion 62,, and the bore of the ratchet wheels is shaped to correspond-with the cross sectional shape of the shaft. To" prevent longitudinal movement of the ratchet wheels with the shaft the hangers 46, '46 'are so arranged that one of the hangers 46 will abut against oneside of the ratchet wheel 60 and the other hanger 46 will abut "against a shoulder 63 formed on the wheel hub. Similarly the wheel 61 isprevented from participating in the longitudinal movement of the shaft 45 by one of the hangers 46 abutting against one side of the ratchet wheel 61 and the other hanger 46 abutting against a shoulder 64 formed.

on the hub of said wheel.

To advance or line space the platen forwardly the ratchet Wheel 61 is rotated LIP-- wardly as viewedin Fig. 3 or in thedirection of the arrow shown in Fig. 18, and to retract or line space the platen backwardly the ratchet wheel 60 is rotated downwardly as viewed in Fig. 3 or in the direction of the arrow shown in Fig. 17. To rotate said wheels 60, 61 a pair of ratchets or pawls 66, 67 are pivotally carried by extensions of rings or collars 68, 69 (Fig. 19) carried loosely on the enlarged portions of the hubs of the wheels 60, 61 and located in the spaces between the respective pairsof hangers 46, 46. I The ratchets have pallets to engage the teeth of the ratchet wheels and the ratchets are so arranged, as shown in Figs. 17 and 18, that as movement is imparted to the ratchet 66 it will move the wheel 60 in a direction" to retract the platen, and as movement'is imparted to the ratchet 67 it will move the gree of advance of the be thrown into engagement with the teeth of the ratchet wheels and moved upward to impart movement to said wheels, this upward movement of the ratchets being permissible due to the loose connection of ,the rings 68 on the hubs of'the wheels, and that this movement of the ratchet wheels will be varied in accordance with the upward movement'of the slides. As the slides are returned, and thereby the ratchets, laterally bent lugs 66', 67 of the ratchets will engage with a beveled portion 68 of the extensions of the rings 68 to which the ratchets are connected. and cause said rings with the ratchets to. move to initial position.

As stated the platen is adapted to be ad vanced or retracted predetermined distances or degrees equal to a single diatonic sound, or a multiple thereof, represented by the ledger lines and spaces of the music staff. For actuating the ratchets to advance or retract the platen such predetermined distances select ve means are provided,

comprising two sets of levers, one set of levers (Figs. 1, 2, 3 and 5) 75, 75 75 and-75 being adapted to raise or hit the slide 70 variable distances to actuate the ratchet 66 to rotate the wheel 60 to retract the platen predetermined distances, and the other set of levers 76, 7 6 7 6 and 7 6 being adapted to raise or lift the slide 71 variable distances to actuate the ratchet 67 to rotate the wheel 51 to advance the platen predetermined distances. Each of the levers 75, 7 5, 7 5? and 7 5 has a finger key 77 connected thereto with the numeral characters 1, 2, 3 and 4 reading from left to right (Fig. 2) and indicative of the degree of retraction of the platen upon the actuation of the respective levers; while each. of the levers 76, 7 6*, 76 and 7 6 has a finger ke 78 with the numeral characters 1, 2, 3 an 4 reading from the right to the left and indicative of the deplaten upon the actuation of such levers.

The slide actuating levers are fulcrumed between their ends upon a rod 78 fixed atv its ends in arms 79 extending forward from vertical posts 80 having shouldered lower ends whereby they are slidably mounted in a cross-bar 81 of the framework and secured at their upper ends to ears 82 depending from the shift rail 26 for a purpose to be hereinafter described. The levers are maintained in spaced relation upon the rod 78' bycollars 83. The forward ends of the levers carrying the finger keys extend through gage slots 85 in a transverse plate 84 secured to the forward ends of the arms 79. These slots 85 are of varying length to regulate the depression of the respective finger key ends of the respective levers and thereby control the raising or lifting of the slides 70, 71 and the. movement im arted to the ratchets 66, 67. The rear en s of the levers are of hammer head shape, as shown at 87, (Figs. 1, 5 and 17,) with the depending portion elongated and the upper edge engaging with the bottom of the slides rounded and arranged so that they normally engage with the bottom of the slides slightly in the rear of the longitudinal center of the slides, but as the levers are actuated the hammer head of the levers moves to a position forward of the longitudinal center of the slides thereby equa zing the shift of the hammer head. Springs 88 mounted on the rod 78 operate to return the levers. The elongated lower ends of the hammer heads serve as guides to. maintain the levers in proper position in the bracket in relation to the slides.

The upper ends of the slides 70, 71 slidably engage in and are guided in openings in guides 90 in the form of a yoke mem- 92 depending from each of the hangers 46,

and each arm of the other guide yoke being secured to a lug 92 depending from each of the other hangers 46. The slides 70, 71 have opposite laterally extending projections 93 to engage over theconnecting portion of the guide yokes to limit the downward movement of the slides, and for a. further urpose to be hereinafter set forth. The slides are returned. to initial position by light springs 94 coiled about the slides and con- 10d fined between collars 95 secured to the slides and the connecting portion of the yoke guides 90.

To adapt the platen advancing and retracting devices as above described to a writing machine in which the platen is arranged to assume two positions, an upper position and a lower position, as by shifting the platen frame by the shift rail 26 as hereinbefore described, and. maintain the platen advancing and retracting means in operative relation with the platen the posts .80 carrying the-lever supporting rod carrying-arms 79 and thereby the levers are connected to the depending ears 82 of the shift rail whereby as the rail is raised or lowered the lever mechanism will be moved therewith. It will also be obvious that as the shaft 45- carrying the ratchet wheels and actuating means therefor is carried by the 1 shift rail such mechanism will also be shifted with the rail, and the slides 70, 71 will also be shifted therewith by the engagement of the projections 93 thereof with the guide yokes 90. It will thus be seen that as the shift rail is moved to what is commonly termed the upper case position the lever mechanism, slides and the platen advancing and retracting means actuated by the slides are lifted therewith as a unit, and as the 1 rail is again lowered such mechanism will be lowered with the rail as a unit.

In operation the blank music paper ruled natures of key and time are printed by actuating the proper key levers for such characters when the writing of the composition or the notation is proceeded with. It is to be =understood that during the writing of the foregoing as the impression making devices are actuated the carriage feeding devices are operated to advance the carriage step by step letter space distances. Should it be desired to raise or lower thetone of a succeeding note one degree the lever actuating the platen advancing or retracting means carrying the numeral character 1 is depressed and the proper music notation printed or written. Should it be desired to raise or lower the tone of the succeeding note two,

three or four degrees, or multiples thereof, either of the levers carrying the numeral characters 2, 3 or 4 is depressed which will advance or retract the platen two, three or four degrees when the music notation is printed, and so on until the music score has been composed or compiled.

To facilitate the manual writing of music signs in connection with the mechanically written characters or music notations, a pa-.

per shelf or table 98 is provided to extend along and above the platen, said shelf inclined downward and forward toward the platen with the leading edge of the shelf above the line of writing on the platen. This shelf is preferably made of sheet material with the side edges bent up right angles to provide guide ledges 98' for the side edges of the paper. The rear longitudinal edge of the shelf is downwardly curled or curved as at 99 to engage over studs i00 carried by brackets 101 secured to and projecting upwardly from the platen frame ends, said studs extending inwardly from the platen frame ends and parallel with the platen. By so mounting the shelf it is adapted to be adjusted to throw the leading edge thereof into or out of engagement with the platen. To maintain the writing sheet in contact and flat against the shelf as it is fed by the platen and feed rollers 41, 42 rollers 102, shown as two in number, are provided to engage with the top of the pa er shelf. These rollers are carried by resi ient arms or fingers 103 mounted on a rod 104 extending longitudinally above the shelf and rotatably'supported at its ends in the shelf ledges 98. To maintain these fingers in position on the rod to yieldingly urge the rollers 102 against the paper shelf, the rod has a flattened portion 105 with which the free ends of a bow spring member 106 carried by the fingers is adapted to normally engage. By this arrangement the fingers may be rotated on the rod independently of each other to throw either one or both ofthe rollers into or out of engagement With the paper shelf, and to adjust the fingers along the rod.

To throw both of the fingers simultaneously out of or into engagement with the paper shelf a finger lever 107 is secured to one end of the rod outside of a shelf ledge 98', this finger. lever being made of resilient material to operate as a detent to retain the rod and fingers in position with the rollers in or out of engagement with the paper shelf. For this purpose the finger lever has a protuberance 108 extending laterally thereof toward the shelf ledge and when the rollers are in engagement with the paper shelf engages in a perforation in the shelf ledge, and when the rod is adjusted to position with the fingers held in position with the rollers out of engagement with the paper shelf said protuberance engages with the top of the shelf ledge. To prevent throwingthe roller carrying fingers too far back an ear 109 is bent laterally from the shelf ledge to serve as a stop for the fingerlever.

To facilitate the manual writing of music signs on the paper shelf in conjunction with the mechanically written music notations there is provided .a templet 110 of transparent sheet material, such as celluloid, (Fig. 21, Sheet 2). This templet is provided with elongated curvilinear edges of regular or irregular form to serve as guiding edges for the writing of slurs and the like, and at the. left hand end with a curved edge a facilitate the writing of braces to connect staffs. One' of the longitudinal edges is provided with a graduated scale representative of spaces of music notation. This templet is placed over the paper on the paper shelf after the mechanically writ-. ten music notations have been impressed thereon and used to mark on the sheet slurs and the like to tie or connect such music notes as it is desired.

As stated it is an object of the invention to provide an improved layout for a key-- board for use in connection with writing machines for the writing of musical composition. For this purpose the usual standard finger key arrangement of commercial typewriting machines is utilized, and shown as consisting of forty two keys connected to impression making devices operating levers and arranged in four alined banks 111,112,

113 and 114. In addition to these keys there the fourth bank of keys the keys for the platen advancing and retracting levers 77, 78 are arranged. These keys are eight in number, the four keys 77 at the left carrying thenumeral characters 1, 2, 3 and 4 reading from left to right, and the four keys 78 at the right carrying numeral characters 1, 2, 3, and 4 reading from right to left, and said characters being indicative of the increment of movement imparted to the platen, either forwardly or backwardly, and such movement being equal to the number of diatonic degrees of the music staff to which 'the platen will be adjusted upon the actuation of such keys. Each of the keys of the banks of keys 111, 112, 113 and 114 carry two music notation characters which are applied directly to the key or are on a tablet which is applied to the keys and are indicative of the characters which will be produced upon the actuation of the keys. In this connection it is tobe understood thatvin the mechanism for writing music notation silent key mechanism is utllized, that is mechanism in which the platen carriage feeding devices will not" be operative upon the actuation of such finger key, thereby permitting the writing of compound music characters. For instance, in' writing the treble clef, in consequence of the large size thereof such character is divided horizontally, the key carrying the lower portion of such character being connected to silent key mechanism and as such key and the connected impression making device are actuated the platen carriage feeding devices are not actuated with the result that when the upper portion of such character is printed which is carried by another key actuated mechanism such por tion of the character will be printed directly above and in conjunction with the lower portion and thereby building up the character. Before writing the upper portion of such character the key 77 carrying the numeral character 4 is depressed thereby retracting the platen four diatonic degrees andpositioning the platen to receive the upper portion of the treble clef character in proper relation to the lower portion which has been printed.

The second bank of keys 112, which is the first in importance, are connected to impression makin devices for the common music notes on t e lower case and which are indicated on said keys; on the left of said bank of keys the note stems extend upward while on the right the stems extend downward. This up and down arrangement of duplicate stems and characters is for the purpose of assisting the operator in'memorizing their positions and to expedite operation. The indications for the characters of the upper case characters follow the same principle.

The third bank of keys .113 and the second in importance are connected to impression making devices for producing simple characters, and such characters as may be compounded or built up, with most of the characters which may be compounded at the right of such bank for operation by the right or dexterous hand. This latter principle in the arrangement of the characters on the keys is repeated in the first and fourth banks of keys. The key at the extreme right in the third bank of keys is also connected tosilent key mechanism. r

The first bankof keys, and thethird in importance carry characters Q representative of simple abbreviations and others that may be built up or compounded.

In the fourth bank of keys, and the fourth in importance, certain of the keys carry 'on the lower case numeral characters representative of appl ing the fingers to the keys or strings of di erent instruments and which are printed upon the actuation of said keys, and other keys of said bank contain special characters and characters to be compounded or'built up. Certain of the keys in the upper case carry numeral characters representative of time and other keys special characters. The third key-from the right in said bank carries the indication of the lower por tion of the trebel clef and is connected to silent key mechanism.

Each of the keys also have five parallel horizontal lines and four spaces between said lines representative of the nine diatonicl sounds'or degrees of the music staff, and two parallel perpendicular lines, and the characters are so located on the keys with relation 2 to said horizontal and perpendicular lines to indicate the position the printed characters will assume on the paper upon theactuation of the respectivekeys with the platen in normalposition and the paper adjusted on the platen with the first line of the staff in register with the platen scale.' In said position of thesplaten and paper the lower case characters will be printed or reproduced on the music paper between the first and second spaces or the first and third lines of the staff in accordance with the size of the character. To raise the tone of a note or, the position of a character indicated by the key gage horizontal lines one,- two, three or four diatonic tones or degrees, or a multiple of suchdegrees, the platen line spacing keys 77 are actuated; to lower the tone or the position of a character one, two, three or four diatonic tones or degrees, or a multiple thereof, the platen line space keys 78 are actuated. The perpendicular position of the notes or characters on the music paper indicated by the perpendicularlines on the keys is changed by the actuation of the platen carriage feeding devices upon the actuation of the impression making devices, The space bar, tabulator key, or back. spacer rey.
