We JOSEPH RICHMOND and WALTER WHITING both of 30 Kirby Street, Hatton
Garden, Middlesex, Engineers, do hereby declare the nature of our said invention
to be as follows:-
This invention relates to certain detail improvements connected with printing
machines and in which a type carrying cylinder has a reciprocating circular motion
and also a down and up motion at the end of each reverse circular travel, the first
motion being for inking and ink distributing purposes, the other for giving the imprint
and for being cleared from the paper.
The cylinder is carried by an excentric shaft which when turned in a certain direction
will prevent the imprint being given.
The inking and ink distributing rollers are carried by end discs which move down
and up with the cylinder but have a reciprocating circular motion over the cylinder
and type in the reverse direction alternately.
According to this invention the cylinder has a flat surface, called the type
back, formed on its periphery and on which flat surface the chase containing
type is fixed, the remaining circular portion of the cylinder forming an inking
surface.
The ends of the spindle passing through cylinder, extend through bearings which
rise and fall in suitable channels provided for them in the side frames of the machine,
such rising and falling motion being obtained by means of connecting rods actuated by
cams or cranks on a countershaft beneath.
This rising and falling motion imparts a motion to the cylinder about its axis by
means of toothed segments attached to the cylinder spindle gearing into racks fixed o
the side frames, such racks and segments being so arranged as to arrest the rotation or
the cylinder at the time when its type back is immediately in register with the
stationary platen of the machine.
In combination with the above are two discs one at each end of the cylinder and
which revolve or reciprocate on the cylinder spindle but move in a reverse direction to

page_text: that in which the cylinder moves, thus obtaining very considerable inking surface for
the rollers to travel over. These discs have radial grooves formed in them into which
fit and slide crossheads, held in their position by spiral springs and free to move in
and out radially to the extent allowed by the springs and guides. These crossheads
carry the ends of the inking rollers which are held in close contact with the whole of
and "give" to the uneven periphery of the cylinder .by means of the lateral play
allowed them by the spiral springs on the crossheads.
Some of these rollers have screw threads cut on their spindles which fit nuts formed
in the crossheads thereby causing a crossways motion of the rollers while they are
revolving. These rollers are known as distributors.
Ink is conveyed to the cylinder by means of a roller receiving a vibratory motion
from a "path cam
22 fixed to the side frame.
By means of the spindle passing through cylinder being made excentric in the centre
when the cylinder revolves on it, the amount of distance between the type back and
platen may be varied and regulated.
The pressure is adjustable from below.

Improvements in or Connected with Printing Presses.
We, JOSEPH RICHMOND and WALTER WHITING, both of 30 Kirby Street, Hatton
Garden, Middlesex, Engineers, 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 certain detail improvements connected with Printing
Machines and in which a type carrying cylinder has a reciprocating circular motion
and also a down and up motion at the end of each reverse circular travel, the first
motion being for inking and ink distributing purposes, the other for giving the imprint
and for being cleared from the paper.
The cylinder is carried by an eccentric shaft, which when turned in a certain
direction will prevent the imprint being given.
The inking and ink distributing rollers are carried by end dises which move down
and up with the cylinder but have a reciprocating circular motion over the cylinder
and type in the reverse direction alternately.
According to this invention, the cylinder has a flat surface ca.led the type
back formed on its periphery and on which Hat surface the chase containing
type is fixed, the remaining circular portion of the cylinder forming an inking
surface.
The ends of the spindle, passing through cylinder, extend through bearings which
rise and fall in suitable channels provided for them in the side frames of the machine,
such rising and falling motion being obtained by means of connecting rods actuated
by cams or cranks on a countershaft beneath.
This rising and falling motion imparts motion to the cylinder about its axis by
means of toothed segments attached to the cylinder spindle gearing into racks fixed
on the side frames, such racks and segments being so arranged as to arrest the rotation
of the cylinder at the time when its type back is immediately in register with the
stationery platen of the machine.
In combination with the above are two discs, one at each end of the cylinder and
which revolve or reciprocate on the cylinder spindle but move in a reverse direction
to that in which the cylinder moves, thus obtaining very considerable inking surface
for the rollers to travel over. These discs have radial grooves formed in them, into
which, fit and slide crossheads held in their position by spiral springs and free to move
in and out radially to the extent allowed by the springs and guides. These crossheads
carry the ends of the inking rollers which are held in close contact with the whole of
and "give" to the uneven periphery of the cylinder by means of the lateral play
allowed them by the spiral springs on the crossheads. Some of these rollers have
screw threads cut on their spindles which fit nuts formed in the crossheads, thereby
causing a crossway motion of the rollers while they are revolving, these rollers are
known as distributors.
Ink is conveyed to the cylinder by means of a roller receiving a vibratory motion
from a "path cam" fixed to the side frame.

page_text: and platen may be varied and regulated:
The invention will be understood by reference to the annexed drawings.
Figure 1 is a front or feeding end of the machine.
Figure 2 a transverse section.
Figure 3 an end elevation.
Figure 4 is a perspective elevation of the same machine, except that the balance
weights are above the frame instead of being below the take off table, as at
Figure 3.
A, A, are two side frames held at their respective distance apart by transverse beam
or girder B, said beam or girder forming the platen of the machine.
C is the cylinder having a pocket D for the type and chase. The cylinder C is
carried by an eccentric E and by means of the bell crank, or other lever the degree
of pressure can be regulated for the imprint or the cylinder be raised sufficiently to
prevent the imprint taking place, said lever being under the care of the workman who
feeds the paper into the machine from the table G.
The eccentric E is carried by the shaft H which has near its outer ends a segmental
toothed wheel I, as seen in Figure 3, and also a pinion J, seen at Figure 2. The
segmental wheel I has a block K forming part of it and when the cylinder is raised
by the crank dises Land rod M, the block K is lifted from between two cheeks N of
the upper frame P, this being forked as indicated at Figure 3. Simultaneously with
the block clearing itself from between the two cheeks N, N, the teeth of the
wheelcome into gear with the racks Q. Q, and as the lift continues, causes the
cylinder to rotate in one direction.
Simultaneously with the rotating action of the cylinder, the pinions J, J, gear into
the racks R, R, said racks being on the opposite fork to that of the teeth Q.
The two pinions J, J, are in connection with discs S which carry the inking
rollers T, T, so that during the rise of the cylinder and shaft H the cylinder rotates in one
direction and the discs and inking rollers in the other direction, the rollers being in
contact with the periphery of the cylinder during their travel for distributing the ink
over the cylinder and on to the type during such rotation.
As the cylinder is brought down by the crank discs L, L, a reverse rotation of the
cylinder and dises take place and by the time the last tooth of the segmental wheel I
are disengaging or going out of gear, the block K takes its position between the two
checks N, N, and which truly registers the position of the cylinder and type for giving
the imprint.
U, U, are counterpoise or balance weights and levers to the rods M, M, and the
cylinder and discs.
V is a director roller against which at each lift of the cylinder an inking roller W
is caused to come into contact, said roller W being on a lever, the opposite end of
which rides in a cam groove X for dabbing the ink which it took from the roller V
onto the cylinder C. This director roller is rotated by the band and pullies Y from
the prime moving shaft Z.
This shaft Z carries a pinion which gears into the spur wheel a for giving the
necessary up and down motion to the rods M, M.
The spur wheel a is on a shaft by which the crank discs L are carried and this
shaft has a couple of cams c, d. The cam c governs the movement of the lever e
which is in connection with a stop or register pin which has to be lowered from
above the platen B when the sheet of paper which has been printed has to be
removed from beneath the cylinder.
g
The cam operates the lever g and this through the knuckle levers h, h, when
the lever is riding on the cam d keep two rollers i, i, clear of the paper while being
fed and during the printing but when the cam is freed from the lever g, said lever
and also fall to bring the two rollers i, i, into contact with other rollers j, j, which
are driven by the band seen at Figure 1, so that the paper becomes nipped
between the rollers i, j, and from the rapid rotation of J it is drawn from under the

page_text: cylinder to fall upon the take off board upon which they lay themselves in super-
posed order due to the angle given to the board 7 which may be a complete board, or
formed of a series of battens, as at Figure 1.
m is a hand lever for throwing the main strap to and from the fast and loose
pulley n for stopping or starting the machine.
pis a similar hand lever for throwing the clutch in and out of gear when the
printing appliances have to be stopped without interfering with the main driving
shaft Z
The lever F is of the bell crank form and according to the degree of pressure
required for printing the lower arm of the lever is adjusted in a quadrant race r, the
lever being affixed on the eccentric but should it be necessary to suddenly stop the
actual printing the Workman or the Attendant who feeds the paper has only to shift
the lever handles to bring a stop against the lever F which alters the position of the
eccentric and consequently prevents the cylinder going down its full distance.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. In a Printing Machine a type carrying cylinder C of the form shown at
Figure 2 of the annexed drawings with a portion of its periphery forming a pocket
for the type and chase, said cylinder having an up and down motion and a rotatory
motion in conjunction therewith as described.
2. Providing a Printing Machine cylinder with a segmental wheel and block as
and for the purposes described.
3. In connection with a Printing Machine cylinder having a rise and fall and
rotatory motion as above set forth, the end discs carrying the inking or distributing
rollers which have a rotatory motion simultaneously with that of the cylinder but in
the reverse direction as described with reference to the annexed drawings.
4. The combination of the parts forming a Printing Machine as described and as
shown in the annexed drawings.
