We, CAROLINE SPILSBURY Pocock of 66 St. Ann's Hill, Wandsworth,
Surrey Gentlewoman and ALFRED WILLMER POCOCK of the same address
Engineer do hereby declare the nature of this invention to be as follows:-
We provide a type carriage of a cylindrical form to hold the types which
carriage is supported over the paper by guides along which it can travel in the
direction of the staff lines. The types are moveable vertically in the cylinder and
are kept in position by springs. The types are brought into position for printing
by turning the cylinder and are then pressed down upon the paper by a presser
which also locks the cylinder for the time being. The paper is secured by suitable
clips or pins to a board which is capable of motion at right angles to the direction
of the staff lines and which is guided in a parallel path by suitable guides or
parallel motion.
The movement of the board is effected either directly or by means of a lever
screw or rack and pinion. The spacing of the characters is effected by the traverse
of the type carriage along the guides by means of rack work and tooth gearing or
any other suitable method. The staff lines are ruled by any suitable pen or roller
which may be fixed to the type carriage or to another carriage moving on the same
guides. The types are inked by pressing against an inking roller or pad or by any
suitable method. A pointer is attached to the type carriage to indicate where the
type will print.

Improvements in Music Type-writers.
We, CAROLINE SPILSBURY POCOCK, Gentlewoman, and ALFRED WILLMER
Pocock, Engineer, both of 66 Saint Ann's Hill, Wandsworth, in the County of
Surrey, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and-by
the following statement:-
We provide a type carriage of a cylindrical forn to hold the types which
carriage is supported over the paper by guides along which it can travel in the
direction of the staff lines.
The types are 'movable vertically in the cylinder and are kept in position by
springs.
The types are brought into position for printing by turning the cylinder and are
then pressed down upon the paper by a presser which also locks the cylinder: for
the time being.
The paper is secured by suitable clips or pins to a board which is capable of
motion at right angles to the direction of the staff lines and which is guided in a
parallel path by suitable guides or parallel motion.
The movement of the board is effected either directly or by means of a lever
screw or rack and pinion.
The spacing of the characters are effected by the traverse of the carriage along
the guides by means of rack work and tooth gearing or any other suitable method.

Figs. 7, and 8, are a section and plan of carriage showing another method of
"making the types so as to avoid the necessity of using a spring to raise each type.

£
A is the carriage carrying the type, B and B are the guides supporting same,
P is the presser which presses the type down onto the paper and at the same time
locks the cylinder by passing down one of the slots cut therein. The presser is
raised by the spring S contained in the handle.K. K is the handle for turning the
cylinder and pressing down the presser. This handle turns loosely in the socket of
the presser P and carries round the cylinder by means of the pin H which is
screwed into the spindle attached to the cylinder. The pin H works in a slot in the
handle K to allow of the vertical movement of the handle. The presser P works
between two collars C C¹ on the handle. D is the board or table for carrying the
paper which is secured to it by, the clips E and E' which can be raised by pressing
the boss X the said clips are kept down by the springs X and X².
The board rests on supports F F F F and is guided by the guide G which works
in slots cut in the projecting pieces L L'.
The said board is moved by the lever M which is pivoted to the frame at M' and
presses between two cheeks N N attached to the guide G.
The carriage is moved along the guides by means of the thumb levers O and R
where upon being pressed down move the rod T the rocking lever T' and the lower
rack T which latter being engaged by the pawl T3 attached to the carriage moves
the carriage.
The rack T rod T and thumb levers O and R are brought back by the spring T¹
attached to the rocking lever T' and the frame.
The two thumb levers are employed for giving different spacing and are so
arranged that if one is pressed the carriage is moved a certain distance which if the
other is pressed the carriage is moved greater or less distance.
Several thumb levers might be employed and so a longer variety of spacing be
provided for.
The carriage is prevented from moving back with the return action of the
rack T2 by the pawl V₁ which is also attached to the carriage, engaging in the
fixed rack V.
.
To move the carriage back the pawls are pushed out of gear with the racks by
the lever Z which has 2 pins upon it to engage the pawls. The carriage can then
be pushed back along the guides.
For convenience a projection may be put upon the carriage which pushes the
lever Z when the carriage is tilted back.
The exact place where the type will print is indicated by a mark upon the
pointer or index plate W which lies over the paper and moves with the carriage.
The types are inked by pressing over the inking roller Y on their descent towards
the paper.
The type characters are cut on the lower end of the spindles a, a, a.
These
spindles work through holes in the plates in the cylinder and are kept up by the
springs S S. The spindles are kept from turning by the pins in their upper ends
taking into the slots in the cylinder. The type character which is cut on the bottom

page_text: of each spindle is indicated by an engraved character under the corresponding slot
on the cylinder.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a music type writer, the combination of the type carriage moving along
over paper in the direction of staff lines with the table for carrying paper moving
underneath type carriage at right angles to direction of staff lines for purpose of
printing music, substantially as herein described and according to the accompanying
drawing.
2. In a music type writer, the combination of the lever M thumb levers O and R
rod T rocking lever T¹ lower rack T pawl T spring T₁ fixed rack V pawl V¹ and
the carriage A, substantially as herein described and according to the accom-
panying drawing
3. In a music type writer, the combination of a movable board or table D the
boss X springs X and X2 with the clips E and E', substantially as herein described
and according to the accompanying drawing.
