Improvements in or connected with Hand Worked Printing
Machines.
I JOHN GOUGH of 30 Kirby Street, Hatton Garden, London, Printers' Engineer
and Machine Maker, 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 :—
This invention relates to a machine for printing from engraved plates and like
surfaces, the operation of inking and wiping the engraved plate being automatic and
under control of a hand wheel by which the printing is effected.
The invention is shown in the annexed drawings.
Figure 1 a perspective elevation.
Figure 2 plan of stop gear.
The machine consists of a base A affixable to a table, said base A is grooved and.
fitted with carrier B upon which the engraved plate it is desired to obtain
impressions from is fixed in any suitable manner.
At the extreme end of an arm a
projecting from the carrier B is fixed an inking or ductor roller E which during its
inward movement rubs the surface of the brush G and supplies it with a sufficient
quantity of ink that is in turn imparted to the surface of the engraved plate fixed
upon the carrier, B. F is a pad and b is a narrow strip of paper passing from the.
reel cover a guide roller & beneath the before mentioned pad F, thence under, over,
and around the various guide rollers d', d', d, to the receiving reel c¹ which is at
every outward movement of the carrier B caused to revolve a portion of a
revolution by means of the stud e, weighted lever K, paul f, and ratchet wheel f¹
affixed to the' reel c'.
By this means, a clean or dry piece of paper is interposed between the engraved
plate and the pad. F to more effectually remove the superfluous ink from the surface
of the engraved plate during its inward movement beneath the pad after having been
inked by the brush G at its extreme outward travel. The necessary movement of
the carrier B and ductor roller E is obtained by turning the wheel H secured to
the end of the screw 9 which forces down the stamp h; the quadrant M is also
turned by the pin i engaging in a hole of the collar S which is in a piece with the
quadrant M and by means of the gear wheels N, P, shaft j, wheel C gearing with
the rack D the semi-rotary movement imparted to the wheel H by the handle k is
transmitted and converted to the rectilinear movement of the carrier B. In order
that the carrier B may be at rest and immovable during the printing operation, the
quadrant M is disengaged from the pinion N and the concave part 1 of the plate Q
fits against the convex surface m of the boss S, thereby locking and preventing any
accidental movement of the gear wheels N, P, C, rack D, and carrier B during the
descent of the stamp upon the paper to be printed that is inserted between said
stamp and the engraved plate upon the carrier B. The motion of the hand
wheel H is limited by the projection into which the pin i is dropped coming into
contact with the stop n. I and J are two powerful springs to counter balance the
weight of the stamp. To prevent any undue shock damaging the first entering
tooth of the quadrant M, a lug R is provided and adapted to abut against the
plate Q at the instant the quadrant M is about to engage the pinion N as
epresented at Figure 2, which shows the plate Q, and lug R, pinion N and
uadrant M just engaging to operate the rack D in the manner before described.

roller E inks the brush G, the stud e moves the lever K over a distance determined
by the pin L which intercepts the return movement of the lever K, thus allowing
it to have a greater or less movement depending upon the position of the pin L in
the series of holes g. The movement of the weighted lever K turns the reel C¹
and causes same to draw the paper from the reel C and expose a clean or dry
surface under the pad F. The outward movement of the carrier is continued until
the engraved plate is inked by passing, under the brush G. On the reverse move-
ment of the wheel H, the carrier returus under the stamp, the plate being wiped in
passing by the strip of paper b to remove the superfluous ink. The quadrant M is
now disengaged from the operating gear N, P, C, D, and the carrier and plate is
stationary and locked in the manner before described. The paper to be printed
is placed upon the engraved plate and the stamp descends to give the necessary
pressure to effect this object. The strip paper d is purposely led away from the
reel to allow of the ink upon same drying before finally being wound upon the
reel. When the reel c' is full, its position is taken by the then empty reel e and
vice versa.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The hand operation printing machine with the several parts arranged in the
manner shown in the annexed drawings and acting in the manner and for the
purposes described.
2. The arrangement of stop gear shown at Figure 2 of the drawings for
preventing motion of movable parts while the press head is lowering and giving the
impression as set forth.
