Abstract: 9983. Rivera, J. S. April 28. No Patent granted (Sealing fee not paid). Type-case machines for writing music; typecarriages; keyboards.-The machine comprises a type-case arranged over a paper-carriage, the typecase carrying a series of key-operated type-levers and being moved longitudinally for characterselection. In the arrangement shown a type-case 7 is mounted on rails 5 and is provided with twentyeight transverse rows of eight keys 8, each transverse set of four keys at the front operating four typelevers A, B, C, D, Fig. 3, with a common printing point on a line under the front of the keyboard and each transverse set of four keys at the rear operating a similar set of four type-levers with a common printing point on a line under the centreline of the keyboard. The type-levers A, B, C, D in each set are of graded lengths and each consists of two side levers through which the keys pass. The keyboard is divided into three transverse divisions a, b, c, which are used respectively for the lower, middle, and higher registers, and each transverse division consists, as described above, of two longitudinal sections. Division a of the keyboard consists of eight transverse rows of keys representing from left to right notes arranged in an ascending order, the notes being repeated in all the keys of the same transverse row, white and black notes with and without stems alternating. The keys in the rear longitudinal section are used for printing mordents. Division c of the keyboard consists of eight transverse rows of keys representing notes for the higher register, the keys being arranged in the same manner as those in division a. Division b of the keyboard consists of twelve transverse rows of keys representing notes for the middle register, sharps, flats, measures, and other signs, some of the keys in the rear longitudinal section being used for printing mordents. This division is also provided with keys 76 for use as described below in ruling. The required note is printed by sliding the typecase until the transverse row of keys containing the note is in a position, with respect to the stave, corresponding to the pitch of the note. If the note is on one of the four front keys, this key is then depressed, but if the note is on one of the four rear keys it is necessary before depressing the key to adjust the sheet, in the manner described below, so that the part of the sheet which is to receive the note is brought under the printing point of the four rear keys. For use in setting the type-case, this is provided at the front with a series of hinged pins each arranged opposite one of the transverse rows of keys, each pin being adapted, by sliding the type-case, to be brought into engagement with one of a series of fourteen registering-holes formed on a scale, not shown, the holes being the same distance apart as the lines of the stave. The scale is secured to a carriage 25 which is mounted on rails 23 and is normally held stationary by a clamping-screw 27. After the printing of one @ave, the carriage 25 is moved and then re-clamped in position corresponding with the desired position of the next stave, this position being determined by a pointer 49 and a scale 22. The type-case is provided with a rack 17 which gears with a loose pinion 36 on the carriage 25. For printing words, the type-case described is replaced by a similar type-case carrying ordinary types. Paper-carriages; sheet-clamping arrangements.- The carriage 3 consists of a flat bed mounted on rails 2. The sheet is secured by corner-clamps 54 which are drawn downwards by springs and can be raised to release the paper by operating eccentrics. Letter spacing mechanism ; carriage - releasing arrangements.-(1) For feeding the paper-carriage through a space of two, three or four millimetres there are provided three keys 65<a>, 65<b>, 65<c> adapted to impart different throws to a lever 66 connected to a lever 69 which carries a pawl engaging a ratchet geared to the carriage. (2) The pawl is connected to a rod 73 which can be pushed inwards to release the carriage. (3) For moving the carriage backward to bring the sheet under the printing point of the rear longitudinal section of the keyboard, a rod 74 is pulled forward. This rod is formed at the end with a rack which can engage the ratchet referred to above. Ruling-devices.-( 1) The stave is ruled by means of a ruling-wheel which is pressed against the sheet while the carriage is being pushed inwards. This ruling - wheel and an inking-roller therefor are carried by a lever which is pivoted in the carriage 25 and is normally held raised by a spring, the carriage being provided with a key-stem which engages the lever and is depressed to bring the ruling-wheel on to the sheet. (2) The type-levers associated with the keys 76 carry ruling-wheels for marking strokes on the stems of notes, these strokes being ruled horizontally. These ruling-wheels are inked by rollers. Ink-ribbons.-The type-case carries two inkribbons which extend along the printing lines and are apertured to permit of the passage of the ruling-wheels associated with the keys 76. The ink-ribbons are mounted on spools 13, 14 but are normally stationary.
