Improvements in Rotary Proof-printing Presses.
1.I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 improvement is designed for taking proof impressions from a galley of type
and its object is to ink the type upon the galley by the passage of the press over it,
and at the same time to automatically feed a strip of paper over the type and take 'an
impression of the latter on the said strip.
In the accompanying drawing :-
Figure 2 is a plan or top view of a proof press embodying my improvement.
Figure 1 is a vertical section of the same taken on the line xx, of Figure 1.
Similar letters of reference designate corresponding parts in both the Figures.
In carrying out my improvement I employ a carriage A, in which carriage are
and
journalled an axle A', and an axle A2. Upon the axle A are mounted wheels A³,
upon the axle A² are mounted wheels A. Upon these wheels the carriage "may"
be moved along. The inner periphery of one of the wheels A³ is provided with
a gear As. A designates an inking roller which may be covered with com-
position as is usual. This roller is journalled in the carriage A and is provided
at one end with a gear wheel A', which meshes with the gear A upon the wheel: A³.
When therefore the carriage A is moved along, rotary motion will be imparted to the
inking roller A
In contact with the inking roller: A is a distributing roller A³ mounted to slide
upon a shaft A' also journalled in the carriage A. This roller is in frictional contact
with the inking roller A and when the latter is rotated the distributing roller is also
rotated. It caused not only to rotate but to have a longitudinal movement along
the surface of the inking roller by means of a reverse screw. A10 upon the shaft A in
a well known manner.
B designates a roller also journalled in the carriage A, upon which is wound a strip
of paper of suitable width B. The strip of paper as unwound from the roll B passes
beneath an impression roller C. The impression roller C is journalled at its ends in a
swinging frame D, which frame is hung upon the carriage A at b; so that it may be
moved freely up and down. E designates springs of which there are two, one upon
each side of the machine, which springs are secured near one of their ends upon a
rod e extending between the side portions of the carriage A and at their other ends
extend beneath projecting portions el upon the frame D. These springs operate to
maintain the frame D, normally. in such a position that should the machine be passing
over a galley of type no impression would be taken. In order to have an impression
the frame D is pressed downwardly by hand and I have shown a handle F upon the
frame D for this purpose.
Assuming that now the machine is being passed over" a galley of type, the
wheels A³, A will rest upon the imposing stone. If now the handle F be pressed
downwardly it will cause the paper B₁ passing beneath the impression roller (to
be brought in contact with the type. If then the machine be moved along with
the inking roller A¹ in advance, the type will be inked and the frictional contact
of the paper B' with the type caused by the impression roller C will cause said paper
to be fed forward off from the roller B and to receive an impression from the
inked type.

page_text: I have shown secured upon the carriage A, a plate G, over which the paper B
will pass to the impression roller C. This plate is loosely secured near its lower
end to the frame D by means of screws d passing through suitably formed slots
in the plate G. When the frame D and the impression roller are swung down-
wardly, the plate G, will be caused to give slightly. The slot connection with the
frame D admits of this. Forwards of the impression roller C and extending between
the side portions of the carriage A, I have shown a bar H which bar constitutes a stop
for preventing a too extended upward movement of the frame D. This bar may be
rotated so as to bring different angles of the bar into position where they will
variously limit the upward movement of the frame D.
Upon the frame is pivotally hung a cutter I, and upon the frame is a plate I
between which and the cutter the paper B¹ will pass when being delivered from the
machine. The width of the cutter I is such that when it has been swung downwardly
in its outer edge will meet the edge of the plate I. The paper B¹ having been
clamped between the cutter I and the plate I', may be torn straight across. Normally
the cutter I is maintained out of contact with the plate I' by means of a spring J
secured near one end upon the frame B and bearing at its other end against the
cutter I.
It will be seen that by my improvement I very readily accomplish the taking of
galley proofs not only in that I ink the galley but that I also take the impression
upon a continuous sheet of paper, all by one operation.
Having now particularly described and ascertained the nature of my 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.. In a proof press the combination with a carriage mounted upon wheels, of an
inking roller rotated during the movement of said carriage, a vertically movable
impression roller, and a paper roller adapted to feed paper beneath said impression
roller; substantially as specified.
Second. In a proof press the combination with a carriage mounted upon wheels, of
an inking roller journalled in said carriage and rotated during the movement thereof,
a frame hung upon said carriage, an impression roller journalled in said frame and a
paper roller adapted to feed paper beneath said impression roller; substantially as
specified.
Third. In a proof press the combination with a carriage mounted upon wheels of
an inking roller journalled in said carriage and rotated during the movement thereof,
a frame hung upon said carriage, an impression roller journalled in said frame,
springs acting to elevate said frame and impression roller and a paper roller adapted
to feed paper beneath said impression roller; substantially as specified.
Fourth. In a proof press, the combination with a carriage mounted upon wheels, of
an inking roller journalled in said carriage, and rotated during the movement thereof,
a frame hung upon said carriage, an impression roller journalled in said frame, a
cutter mounted upon said frame, and a paper roller adapted to feed paper beneath
said impression roller; substantially as specified.
