Improvements in and relating to Machines for Printing Music.
I, HENRY HARRis Lake, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows :-
This invention has for its subject an improved machine by means of which notes
and the various signs employed in music can be printed upon transfer paper, the
staves having been previously produced upon the said paper which serves, after the
whole operation has been terminated, to effect a transfer upon stone or upon zinc in
the ordinary manner.
The improved machine comprises a cast-iron bed or frame provided with two
guides upon which a chariot can be displaced horizontally from the front to the rear
by means of a screw. This screw is turned by hand, the amount of the displace-
ment being controlled by an index which is fixed to the said chariot and placed
above a scale forming one piece with the frame of the machine.
The said chariot carries a second chariot which may be displaced from right to
left upon the guides on the former in order to effect the displacements necessary for
suitably spacing along the staves the notes, signs and characters employed in music.
This movement is effected very accurately by means of a lever which is caused to
engage at the desired moment by means of a pawl with a toothed wheel keyed upon
a shaft.
This shaft, which is grooved longitudinally and supported by brackets
fixed to the chariot, carries a sleeve which may be displaced upon it in the
longitudinal direction, but turns therewith. The said sleeve is made in one piece
with a helicoidal pinion gearing with a similar second pinion keyed upon a screw
traversing a nut which is secured upon the second chariot. When in this arrange-
ment the aforesaid wheel is turned by means of the lever the screw turns at the
same time and causes the second chariot to advance from right to left.
In order that the forward movement shall always be exact I employ a disc
provided with holes into which are introduced pins against which the levers strike.
For controlling the displacements of the second chariot in the transverse
direction the latter is provided with an index passing over a scale fixed upon the
first chariot.
Upon the second chariot is provided a third chariot adapted to slide rearwards,
this movement having for its object to place the notes at the proper height upon
the staves by means of the device hereinafter described.
On the second chariot is fixed a guide having a slide adjusted upon it and
connected by a small rod to the left hand extremity of a graduated rule the right
hand extremity of which is attached by another similar rod to the second chariot.
On the other hand the third chariot carries a fixed second graduated rule, and
upon these rules can be displaced two runners articulated one upon the other.
Outside this the second chariot is provided with a plate in which are formed
sufficiently deep grooves representing the stave with its supplementary lines. Into
these grooves is introduced a spring finger fixed upon the aforesaid slide. It is
sufficient to raise the finger and to push by hand the slide and consequently the
third chariot for bringing the finger into the groove corresponding to the desired
note.
By displacing the runners upon the graduated rules the length of the rearward
movement of the third chariot may be varied according to the size of the staves.

page_text: On the third chariot is mounted a turning disc made in one piece with a toothed
crown, with which engages a pawl fixed to the third chariot so as to keep the disc
in accordance with the inclination which has been given it.
This disc is covered with a thin sheet of india rubber for rendering the pressure
more gentle, and carries the sheet of transfer paper upon which the notes are to be
printed. The said sheet is pierced on the right and left hand side by two points
fixed to the disc, and is held in its place by hinges which turn down upon it.
The mechanism for displacing the paper having been described I will now proceed
to describe the printing mechanism.
At the rear part of the bed or frame of the machine is a bracket in the form of
a swan's neck carrying the printing mechanism possessing as its principal part a
wheel upon the periphery of which are engraved in relief the musical signs, the
same signs being repeated upon the flat part of the rim for guiding the operator.
The said wheel, whose axis is fixed to a slide, is turned by a handle for placing the
desired sign perpendicularly. This wheel is held in its place by means of a pawl
carried by the said handle and adapted to engage with the notches in a crown fixed
upon the slide above referred to.
This slide moves vertically in a box fixed upon the said bracket by means of a
pedal placed under the machine and which, being connected to a rod, causes a lever
to oscillate upon its supports. By pressing the pedal the operator causes the said
slide to descend, and when the pedal is released a counterweight causes the slide to
rise again.
The supports carry a lever having four arms connected to the above-mentioned
lever. Upon the extremities of these four arms are articulated four vertical rcds
which act in the following manner.
When the pedal is pressed down the said lever and also the four arms are caused
to oscillate. The connecting rod acts first and as it descends throws to the left the
articulated index which serves only to indicate the point where the impression is to
be made. Directly afterwards two of the four rods act upon the articulated heel-
pieces of arms and move forwards the inking roller below the wheel of the printing
mechanism for inking the type placed at the lowest part. As the two rods
continue to descend they escape from the heel-pieces of the said arms, and the
inking roller, under the action of the springs, moves quickly rearwards upon the
inking table.
During this time one of the connecting rods always causes the said slide to
descend, so that the wheel of the printing mechanism will finally print a sign upon
the sheet of paper carried by the disc.
The operator takes a sheet of paper upon which staves have previously been
drawn with transfer ink, and places it upon the disc. He then turns over the
hinges, and having disengaged the pawl he regulates the inclination of the disc in
such a manner that the staves shall be perfectly parallel with the transverse motion
of the said disc. After this he pushes the chariots below the wheel of the printing
mechanism and turns the shaft for moving the point of the paper where the
impression is to commence exactly below the index, which is effected by pressing
down the pedal. He then actuates the lever for shifting the paper laterally, pushes
the slide so that the finger enters the groove in the rule corresponding to the
desired note, presses down the pedal in order to print the second note, and continues
in the same manner.

page_text: The improved machine comprises a bed or frame A provided with two guides a¹
upon which a carriage B can be displaced horizontally from the front to the rear
by means of a screw b.
The said carriage B carries a second carriage C upon which is permanently fixed
a plate D; the carriage C being adapted to slide rearwards in guides c.
Upon the plate D are placed the sheets to be printed; a Bristol board or a sheet
of gelatine pasted upon the said plate renders the pressure more gentle.
The sheets of transfer paper are ruled with vertical lines placed one millimetre
apart from each other, every tenth line being thicker; these lines guide the.
operator for placing the notes along the staves.
I place upon the plate Da sheet to be printed, placing its left edge below the
hinge K taking care to make one of the lines on the paper correspond with the
edge of the hinge which is tightened by means of screws k, the same operation takes
place on the right, and when the paper is fixed on both sides I lower the rod k¹,
which, entering the channel ", finally stretches the
paper.
On the left of the plate B is a small carriage E fitting upon the guide F and
adapted to slide on it; a copper plate e of suitable form is fixed by its thin part
below the left side of the said carriage E and forms one piece with it; on the part
which protrudes are engraved deep and sufficiently broad lines representing to a
very large scale a stave and its accessory lines. A spring placed above the
plate e and fixed upon the carriage B is provided below with a tooth which enters.
one of the notches in the plate e; a pointer fixed upon the guide F indicates to
the operator the notch into which the tooth is to pass.
Three branches of a parallelogram G G G (Figure 3) are fixed one on the
right upon the carriage B, one on the left upon the carriage E, that which connects
them carries a slide y pivoted upon a similar slide placed on a fourth branch G
of the parallelogram fixed below the carriage C; the two branches which have
slides are graduated for regulating the extent of the displacement which takes
place upon the carriage C and the plate D according to the size of the music to be
printed.
This parallelogram is the apparatus which permits of automatically placing the
notes at their value upon the stave; in fact when with the lever H, the extremity h
of which is connected to the copper plate e, I cause the forward or backward
movement of this plate and the carriage E to which it is attached this carriage
which carries one of the branches of the parallelogram moves the latter which in
its turn moves the carriage C; this carriage places below the printing wheel, the
plate D and the sheet which it supports at the place which the desired note is to
occupy.

page_text: All the movements which take place upon the lower part of the machine having
been explained I will now proceed to describe the printing mechanism.
Upon two feet I (Figure 1) is fixed a large guide J; on this guide is provided
a carriage L which is moved upon the guide by the screw M which by means of
return movement and gear wheels is actuated by a counter N placed on the
frame A stops regulate the movement of the counter which can be actuated
either by hand or automatically by means of a pedal placed below the table; in
this case the parts o are connected to the lever of the counter; their pivot is placed
at Q, and to the part o' is connected a rod which passes to the pedal; a spring R
moves the lever back to its original position.
If the part o¹ is prolonged I may provide a handle by which the movement may
be effected by hand and more rapidly.
Upon the carriage L moves downwards a slide S carrying a wheel T on which
are engraved in relief the musical notes and the letters necessary for producing the
music and the words at the same time.
The handle which serves to turn this wheel is hollow; a rod placed in the
interior will at the least pressure raise a pawl one of the extremities of which can
engage with the notches in a wheel U placed behind the wheel T and fixed on the
slide S; the notches in the wheel U are equal in number to the signs engraved on
the wheel T. On the sides of the carriage L are placed two arms V between
which can move a rocking lever X provided with two arms Y and Z; the first
which is longest must, when movement is imparted to the rocking lever, cause
the pointer y to deviate horizontally with its connecting rod y; a cam attached
to this connecting rod determines the said movement; afterwards the arm Z will
cause the downward movement of the slide S carrying the wheel T. In the
articulation of the connecting rod t provision is made for lost time, in order that
the movement may take place only after the roller will have passed below the said
wheel; this is effected in the following manner :
To the rear of the carriage L is fixed an arm 1 the lower extremity of which
carries an ink table 2; on the ink table is a train of rollers 3 the first of which
must only pass below the wheel T and ink the sign to be printed; its axis is very
long and extends beyond the train on the two sides; the part which projects has
notches which enable it to be displaced in order that the same part may not pass
consecutively upon the lines to be inked and may not be deteriorated; a screw a
passes into a notch and fixes the ink roller in its place while allowing it to turn ;
the others serve only to distribute the ink upon the table.
The upper part of the piece I is traversed by two shafts 4 and 5; the shaft 4
on the left carries a lever arm 6 which attached to the train of rollers; a cam 7
which rises without producing any action forms part of this arm; upon the shaft 5
is fixed another cam 8 which bears upon the cam 7; when the latter is lowered by
the movement hereinafter described it moves forward the arm 6 which pushes the
train of rollers until the first roller has passed below the wheel T; at this moment
a pin 9 placed at the extremity of the arm 10 encounters a fresh cam 11 forming
part of a similar lever to the lever 6 and moves the train of rollers to the rear.
For setting all these parts in motion I use a rod or tail-piece 12 fixed to the
rocking lever X; upon this tail-piece is fixed at its middle part a sleeve 13 having
a rod 14 which is pivoted to the lever 15 fixed to the shaft 5. At the extremity
of the rod 12 another sleeve 16 carries also a rod 17 connected so that it can slide
to the rocking lever 18 pivoted upon the points 19,-19; an arm 20 provided with
a handle moves forward in front of the machine within reach of the hand. If this
arm 20 is lowered the rear part of the rocking lever is raised, and in its turn raises
the rod 12; the latter first lowers the arms Y and Z, but only the former produces
its effect at once, at the same time the arm 15 drawn by the rod 14 lowers the
cam 8 which afterwards acts upon the cam 7 and moves the rollers forwards; the
pin 9 of the arm 10 immediately encounters the cam 11 and throws backwards
the train of rollers; then the wheel T is lowered and one of its musical signs is
printed.

page_text: A spring concealed in the material of the carriage L and slide S serves to raise
the wheel, being greatly assisted by the weight of the rocking lever.
This latter, provided for the convenience of women who do this work may be
advantageously replaced by a pedal arranged under the table when the work is
done by a man.
The wheel with type engraved in relief may be replaced by a wheel provided
with cavities or recesses into which is introduced movable type either of printer's
metal or of engraved steel each fixed by a screw and capable of being changed at
will when worn or deteriorated.
With type of tempered steel I can stamp in intaglio a plastic material enabling
typographic stereotyping to be effected, and with type engraved on the spot I can
directly stamp a metal for copper print.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is
First. The improved machine constructed and arranged substantially as herein-
before described.
Second. The mechanism for enabling the notes to be automatically put in their
place upon the stave.
Third. The employment of pedals for printing or stamping music on any material
which is suitable for that purpose.
Fourth. The employment of an automatic counter for regularly spacing the notes
when it is necessary, and the disengaging device for the said counter.
Fifth. The employment of transfer paper ruled vertically which enables the
notes to be very rapidly placed in the vertical position while working in the
direction of the stave.
Sixth. The employment of a wheel carrying a series of type or two alphabets,
capitals and small letters, with a handle for enabling the connection to be effected
at will.
Sevench. The employment, in a machine for the above described purpose, of a
device for inking by means of rollers.
Eighth. The employment of a system of pincers and a stretcher for fixing the
paper, substantially as described and represented in the drawings.
