Improvements in Type Writing Apparatus.
"
I, MARSHALL ARTHUR WIER of 3 Palace Grove, Upper Norwood, in the County
of Surrey, Engineer, do hereby declare the nature of the said invention for
IMPROVEMENTS IN TYPE WRITING APPARATUS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying sheets of drawings and to the
letters and figures marked thereon:-
This invention relates more especially to type writing apparatus of the kind for
which I applied for a patent on the 10th day of March, A.D. 1885 N° 30S0, but
part of the said invention is applicable also to certain other type writing apparatus.
The improvements constituting the present invention relate to the flexible type
printing bands employed in my aforesaid type writing apparatus, and to appliances
for printing music by means of such apparatus or by other type writing apparatus
to which the said improvements may be applicable.
The improvements in the flexible type printing bands consist as follows:-In the
specification of my aforesaid application for Patent N° 3080, I have described a
type band of indiarubber having the printing type formed or moulded with the
said band, or metal type secured to the said indiarubber band as a base. Now
instead of the indiarubber band I employ a band made of a woven fabric, such as
ordinary tape for example, and I attach to the said woven band metallic type made
of ordinary type metal by casting the said type in open moulds and applying to
the back thereof, while still in a molten state or before the metal sets, the tape to
which the type is to be attached; by pressing the tape down on to the back of the
type the metal is forced through the spaces between the threads of the fabric, and
by then lightly hammering or pressing the parts of the type so pressed through
the fabric, the type becomes rivetted firmly to the tape. Fine wire gauze or
perforated metal may be substituted for the tape. Or 1 make the band of any
suitable flexible material, sheet metal or leather for example and I rivet the type
thereto by rivets cast on the type passing through holes in the flexible band aud
rivetted over at the back of the latter, or by rivets passed through both type and
band. Or if the type and band be made of metal that can be soldered or brazed,
that method of attachment may be employed. The flexible band may also be
formed of a chain of suitably shaped links, or of pieces of metal or other material
hinged together. According to another modification the band may be made of a
strip of flexible metal, such as copper or steel, on which the type may be formed or
raised by means of punches, or by pressure, after the manner of what is known as
"repoussé" work. I sometimes arrange two rows of type on the band and mount

page_text: the printing pad (which in this case is preferably of a cylindrical form as herein-
after described) so that it may be raised and lowered alternately in such manner as
to bring the surface of the pad or cylinder opposite to either the upper or the lower
row of type as desired, the face of the sliding printing block being in this case flat
instead of curved as hereinafter described.
The improvements in the devices or appliances for printing music consist of the
arrangements shown in the accompanying Drawings in which Figure 1 is a plan
of my aforesaid type writing apparatus with my present improvements applied
thereto, Figure 2 is a side elevation of same, Figure 3 a partial section on line 1—1
of Figure 1, Figure 4 a section on line 2-2 of Figures 1 and 2 and Figures 5
and 6 detached views, to an enlarged scale, of parts to be hereafter described.
The type writing apparatus shown is in all material respects similar to that
described in the specification filed with my aforesaid application No. 3080, but the
flexible type band A may be made as therein described, or as hereinbefore
described, and is made wider in order to include the stems of the musical notes
when such are required; and the end of the sliding block V, which presses the
type band A against the paper W on the printing pad W1, is curved to correspond
with the shape of the latter, which is shaped as a segment of a cylinder. This
printing pad W₁ is pivotted loosely at W8 so that its surface can be oscillated by
the lever handle W in order to bring any required part of the paper W on the
printing pad W. opposite to the type on the type band A the spring catch W13
serving to hold the printing pad in the desired position. The paper W to be
printed on is ruled with the staff lines in the usual way and is carried between the
pressure rollers W2 W3 W4, and over the surface of the printing pad W¹ as shown
in dotted lines in Figures 2 and 3, being held fast between the rollers W2 W* and
the roller W3 by the spring arms Wo W7 on the ends of which the said rollers Wa
and Ware mounted. The paper W is wound on or off the rollers W, W³, W by
means of the handle W19 W is a segmental scale which is connected to the
printing pad W by the hooks or pegs Wo so as to partake of the same movement
as the printing pad W¹. On the segmental surface of the scale W° are ruled a
series of lines corresponding to the staff lines and leger lines of the music paper,
the leger lines being distinguished from the ordinary staff lines by being coloured
W11 is an index
red or dotted, or having some other distinguishing characteristic.
pointer fastened to the carriage C and traversing along over the scale W° as the
carriage C is moved to and fro in front of the latter. It will now be understood
that the paper W can be adjusted on the printing pad W₁ so that any one of its
staff lines or leger lines, or the spaces between them will stand opposite the type
on the type band A when, by the movement of the handle W, the corresponding
line or space on the scale W is brought to the point of the index pointer W, and
that thereby the printing of the note or sign on the desired line or space on the
paper can be secured with great precision. Or I sometimes employ a printing
cylinder round which the ruled paper is wound once round, and fastened by means
of elastic bands or otherwise, in such manner that the space between the top and
bottom pairs of staves, when in position on the cylinder, shall be equal to the spaces
separating the other pairs of staves on the paper. By this arrangement the scale W9,
the rollers W2 W3 W and printing pad W₁ may be dispensed with, the staff lines on
the paper itself serving for a scale to the index W" and the printing cylinder as a
printing pad.
The action of the apparatus is as follows: The ruled paper being accurately
adjusted over the printing pad W₁ the carriage C is placed opposite the part of the
paper where the note or sign is to be printed, the slider D is then moved along the
carriage C until the pointer O points to the note or sign on the scale or index
plate Pit is desired to print on the paper, this motion of the slider D brings the
part of the type band A which carries the note or sign corresponding to that
opposite to which the index O has been set, in front of the sliding block V and
opposite to the printing pad W₁; the handle W³ is then, or previously, operated so
as to bring the required line or space on the scale W to the point of the index W",

page_text: and thereby the corresponding line or space on the paper W opposite the note or
sign on the type band A; the pin L is then pushed down through the hole in the
plate I corresponding to the note or sign on the scale or index plate P opposite to
which the pointer O had been brought, and the hinged plate H is thereby depressed
drawing down the link U, turning the bell crank lever T on its fulcrum, and
thereby forcing outwards the sliding block V against the pressure of the spring V².
This movement of the block V carries the part of the type band A. which may be
in front of it against the paper W on the printing pad W¹, printing the desired
not or sign thereon.
It will be seen that there are two rows of notes and signs marked on the scale
or index plate P; the printing type corresponding to one of these lines of notes or
signs are carried on one part of the type band A, and the printing type
corresponding to the other line of notes or signs is carried on another part of the
type band A.
When it is desired to print notes or signs which are shown on the
second line on the scale P, the cross slide D³ is placed in the position shown in
Figure 1, so as to engage with the type band A on the side of the carriage C next
the scale or index plate P, and in that case the pin L takes into the second row of
holes in the plate I. When it is desired to print notes or signs which are shown
on the first line on the scale P, the cross slide D³ is moved so as to be disengaged
from the band A on that side of the carriage and to engage with it on the other
side thereof, and in that case the pin L takes into the first row of holes in the
plate I. In order to prevent the cross slide D³ from becoming disengaged from the
band A, except when desired, the spring latch f provided on the slider D
the latch portion holding the cross slide D³ in position. When it is desired to shift
the cross slide D³ out of gear with one portion of the band, and into gear with the
opposite portion, the slider D is drawn along until the pin g on the frame: C comes
in contact with the tail of the spring latch f and forces the latter out of position,
when the cross slide D³ can be shifted as desired, and on moving the slider D away
from the ping the spring latch will again act to retain or lock the cross slide D³ in
its new position. In some cases I employ a narrow slot instead of a series of holes
in the plate I with any suitable arrangement of ratchets or recesses and spring
pawls for guiding the slider D into position opposite the required letter.
The inking of the type band may be effected by means similar to those described
in the specification of my aforesaid application for Patent No.. 3080, but when the
band is comparatively wide as in the case of music writing, I prefer to employ two
inking rollers X X turning loosely in bearings in the carriage: these rollers are
covered with felt or other material capable of absorbing the ink which is applied to
them from time to time as required, and they are arranged to press and roll lightly
against the surface of the type on the type band A as the latter is moved by the
slider D, or instead of the rollers XX stationary inking pads or brushes may be
employed.
The carriage C may be made to traverse automatically along in front of the paper
each time a note or sign is printed, so as to give the necessary spaces between each
note or sign by means of the traversing apparatus shown in the sectional Figure 4,
in a manner similar to that described in the specification of my aforesaid application
No. 3080, but when printing music, in which the spaces. vary considerably, it is
generally found preferable to move the carriage C by hand, or by pressing down
the key R¹ as many times as will produce the required traverse by the action of
the pawl R on the feeding rack or indiarubber strip S.
For the purpose of ruling the lines indicating the value of the notes in music of
lower denomination than crotchets (commonly called the tails) I employ the
apparatus shown in Figures 1, 2 and 3 and, to an enlarged scale, in Figures 5
and 6. This apparatus consists of a frame a in which are mounted series of rollers
or discs 6 turning freely on their centres in the frame a, each series varying in
number according to the number of lines or tails required to indicate the value of
the notes; for example, a single roller or disc for a quaver, two rollers or discs for
a semiquaver, and so on. An inking roller c turning loosely on the centre of the

page_text: frame a, and in contact with all the series of rolls or discs, supplies the same with
ink. The apparatus is secured to the carriage C by a thumb screw d in such a
position that any one of the series of rollers or discs may be made to bear, when
the apparatus is pressed down by the finger, on the paper and the carriage C being
then moved laterally to the required distance the rollers or discs will roll on the
paper and trace one, two, three or more lines in connection with the notes,
indicating their value in the usual way. When these lines are to be drawn
obliquely on the paper it is only necessary to place the ruling apparatus at the
required angle in relation to the curved printing pad W₁, and then when the
carriage C is traversed laterally the angular position of the rollers or discs causes
the said pad W¹ to rotate slightly at the same time, and the lines drawn then stand
obliquely on the paper. The rotation of the pad W¹, by this action of the rollers or
discs, is facilitated by properly counterbalancing the pad W₁ on its centre. The
required series of rollers or discs is brought into action by slackening the thumb
screw e and turning the frame a round on its axis till the required series of rollers
or discs is brought opposite the paper, and the thumb screw e is then tightened so
as to prevent the frame a from turning.
When the type band A is made non-elastic, or only slightly elastic, it is desirable
in some cases to insert in it, at some convenient point, a spring or other elastic
medium to enable the sliding block V to carry the said type band A forward into
contact with the paper W without unduly straining the said band.
It is obvious that the appliances above described for enabling music. to be
printed may be applied to type writing apparatuses other than those forming the
subject of my aforesaid prior application for a Patent No. 3080; for example, they
may be applied to the well known "Remington" type writer, or to others acting
in such manner as to admit of the application thereto of the aforesaid music
writing or printing appliances.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
First In type writing apparatus the employment of flexible type printing
bands composed of woven or perforated material, flexible metal, or chains having
type secured thereto, or of flexible metal on which the type are formed or raised
by means of punches, or by pressure, as herein before described.
Second-In type writing apparatus the appliances for writing or printing music,
consisting of the curved or cylindrical printing pad moveable about a centre in
combination with means for holding the paper on the said pad, the curved index
mounted on and moveable with the said printing pad, and the index pointer
mounted on the printing carriage, the whole arranged, combined and operating
substantially as herein before described and illustrated in the Drawings hereto
annexed.
Third In type writing apparatus the employment of a double row of type on
the printing band in combination with a printing pad or cylinder so mounted that
its surface may be brought into line with either of such rows of type, substantially
as herein before described.
