I, JAMES DOUGLAS DALLAS, of 10 Trevor Terrace Rutland Gate, London, S.W.,
Electrician, do hereby declare the nature of this invention to be as follows :---
My invention for improvements in apparatus for setting up type consists of apparatus
in which each type is liberated from a box, containing a number of each type of the
set in separate compartments, by depressing a corresponding key and is led by suitable
races or guides to a main race or guide from which the said type passes to its proper
position; the box and races being mounted on a carriage which is fed onwards on a
main frame after each type is deposited so as to leave the main race in the proper
position for depositing the next type.
In apparatus constructed according to my invention a number of each distinct type
is contained in a separate compartment of a box each compartment being so inclined
that the type slide down to its lower end at which is a hole through which the type
passes to a supplementary race leading to a main race. Normally the said hole is
covered by a small plate which prevents the passage of the said type to the race but on
the depression of a key corresponding to the said type an electric circuit is closed and
causes a solenoid in the said circuit to attract its armature or core which is attached to
the said plate and so causes a hole in the said plate to come opposite the hole in the type
compartment so that the type is free to pass to the supplementary race. When the
key is released a spring draws the small plate back to its normal position. Small
springs at the bottom of the main race and between which the type passes, absorb by
friction the momentum of the type and prevent its rebounding. There is a separate key
with electric circuit, type compartment, small plate and supplementary race for each
distinct type.
In order that the box containing the type and races may be fed onwards after each
type is deposited, the circuit of a large electro-magnet is arranged to be closed on the
depression of any one of the aforesaid keys and this electro-magnet thus attracts its
armature which through a pawl lever pivotted to the main frame acts on a rack attached
to the box which is thus moved onwards. The box is mounted on wheels running in

page_text: grooves in the main frame. The electro-magnet is fixed to the main frame and
connected to the circuits of the solenoids by flexible cords.
At the end of each line, the box is slid back to the position occupied when com-
mencing to set up the line by means of a small handle attached to the box and the
framework holding the set up type is slid forward on the main frame by hand so as
to bring it in position for receiving the type from the main race for setting up the
next line.

page_text: I, JAMES DOUGLAS DALLAS, of 10 Trevor Terrace, Rutland Gate, London, S.W.
Electrician, 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 :-
My invention for improvements in apparatus for setting up type consists of apparatus
in which each type is liberated from a box containing a number of each type of the
set in separate compartments, by depressing a corresponding key and is led by
suitable races or guides to a main race or guide from which the said type passes to its
proper position; the box and races being mounted on a carriage which is fed onwards
on a main frame after each type is deposited so as to leave the main race in the proper
position for depositing the next type.
In apparatus constructed according to my invention, a number of each distinct
type is contained in a separate compartment of a box, each compartment being
so inclined that the type slide down to its lower end at which is a hole through
which the type passes to a supplementary race leading to a main race. Normally.
the said hole is covered by a small plate which prevents the passage of the said
type to the race, but on the depression of the key corresponding to the said
type an electric circuit is closed and causes a solenoid in the said circuit to attract
its armature or core which is attached to the said plate and so causes a hole
in the said plate to come opposite the hole in the type compartment so that the
type is free to pass to the supplementary race. When the key is released a spring
draws the small plate back to its normal position. Small springs at the bottom
of the main race, and between which the type passes, absorb by friction the momentum
of the type and prevent its rebounding. There is a separate key with electric circuit,
type compartiment, small plate, and supplementary race for each distinct type.
In order that the box containing the type and races may be fed onwards after each
type is deposited, the circuit of a large electro-magnet is arranged to be closed on the
depression of any one of the aforesaid keys, and this electro-magnet thus attracts its
armature which, through a pawl lever and pawl acts on a rack attached to the box,
which is thus moved onwards. The box is mounted on wheels running in grooves in
the main frame. The electro-magnet is fixed to the main frame and is connected to
the circuits of the solenoids by flexible cords.
At the end of each line, the box is slid back to the position occupied when com-
mencing to set up the line by means of a shunt or compound wound electric motor,
connected to the spindle on which the wheels carrying the body of the typesetter are
mounted. The framework holding the set up type is slid forward on the main frame
by hand so as to bring it in position for receiving the type from the main race for
setting up the next line.
In the accompanying sheet of illustrative drawings: Fig. 1 is a sectional side
elevation of part of a compartment containing type, shewing the race with small
plate and electro magnet for passing the type. Fig. 2 is an enlarged perspective view

page_text: of the small covering plate. Figs. 3 and are front and side elevation respectively of
a part of the supplementary race and pointer for conveying the selected type to the
form. Figs. 5 and 6 are cross section and side elevation respectively of mechanism
for carrying forward the main frame when each type is deposited, and Fig. 7 is a
diagram shewing the electrical connections.
A number of each distinct type a is contained in a separate compartment 6 of a box,
each compartment being so inclined that the type slide down to its lower end at which
is a hole c through which the type passes to a supplementary race d. Normally the
said hole is covered by a small plate e which prevents the passage of the said type to
the race, but on the depression of a key f corresponding to the said type an electric
circuit is closed and causes a solenoid g in the said circuit to attract its armature or
core h which is attached to the said plate e, and so causes a hole i in the said plate to
come opposite the hole c in the type compartment, so that the type is free to pass to
the supplementary race d. When the key f is released, a spring; draws the small
plate e back to its normal position.
In order that the box containing the type and races may be fed onwards after each
type is deposited the circuit of a large electro-magnet k is arranged to be closed on the
depression of any of the aforesaid keys, and this electro-magnet then attracts its
armature which, through a pawl lever m, and pawl n, acts on a rack o attached to
the box, which is thus moved onwards. The box is mounted on whoels ? running in
grooves q in the main frame. The electro-magnet k is fixed to the main frame, and is
connected to the circuits of the solenoids g by flexible cords r.
At the end of each line the box is slid back to the position occupied when com-
mencing to set up the line by means of an electric motor s connected to a spindle t on
which the wheels p carrying the body of the typesetter are mounted.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In apparatus for setting up type:
a hole
1. Arranging each distinct type in a separate inclined compartment having
in its lower end through which the type passes into a supplementary race, the said
hole being normally covered by a small plate having a hole in it and being attached
to the armature or core of a solenoid so that, when a key corresponding to the said
type is depressed, an electric circuit is closed, and causes the solenoid to attract the
said armature and bring the hole in the said plate opposite the hole in the type com-
partment, and thus allow a type to pass from the inclined type compartment to the
supplementary race substantially as described.
2. Feeding forward the type box after each type has been deposited by means of a
rack and pawl connected to an armature actuated by an electro-magnet connected to
the circuit of the type keys in such manner that, on the depression of any type key
the current passes through the said magnet, substantially as described.
3. The arrangement and construction of apparatus for setting up type substantially
as described with reference to the drawings.
