MENTS IN WOOD PRINTING MACHINES
Year: 1886

page_text: I, JOHN COLLIS, No 12 and 14 Ironmonger Row, Saint Luke's, in the County of
Middlesex, Engineer, do hereby declare the nature of my invention for IMPROVE-
MENTS IN WOOD PRINTING MACHINES, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention consists of a machine with automatic adjusting cylinder, inking
and feeding arrangement in the manner as hereinafter described and shown in the
accompanying drawings.
This machine is provided with two principal cylinders, an upper and a lower
one; the upper one "A" Figure 3 which carries the lettering or type on the one
half "a" of its circumference, the other half "a1" acting as the inking slab.
This cylinder is provided on its ends with cams "b and b 1."
The cams are so shaped as to rise the inking rollers on to, and guide them
over the lettering or type, and lower them on to the inking slab as the cylinder is
revolving.
"
There are five inking rollers "d, d1, d2, d3, and d 4," of which "d3 and ₫ 4”
have besides a rotary a reciprocating motion which is effected by the fork " C
which is operated by a crank “c1" and a cam "c2" geared from the shaft of the
cylinder "A."
An ordinary adjustable ink feeder and ductor roller “e," is placed in a suitable
position near the cylinder "A"
The ink is transferred from the ductor roller on to the inking slab by a vibrating
roller "f" fitted in an adjustable frame "f1." The vibrating motion is given to
the roller by the cams "6 and 61" on the cylinder "A" and returned by a lever
and weight "f2." The lower cylinder "B" is an adjustable one, carried in box
bearings "g and 91" sliding in the side frames "m and m 1" and fitted with half
bearings "h and h1" carried by spiral springs " and 1" which rest on the
adjusting screws "k and k1" in the box bearings; the box bearings are carried on
an adjusting arrangement as follows:-
On the lower cross bar which connects the two side frames, are two carriage
brackets" and 1," see Figure 3, fitted with a cylinder "n" carrying a hand
wheel" 1."

page_text: The cylinder "n
" is screwed with a right and left handed thread inside, into
which two screws " o and ol are fitted. These screws are provided with wedge
blocks "p and p1" on to which rest the lower end of the box bearing which forms
a counter part to the wedges, which latter rest in the frame "m."
This lower portion of the box bearing is fitted with the adjustable screws
"k and k1" which carry the springs.
"
"

Adjustment is effected by turning the cylinder n by means of the band
wheel "nl" to the required direction by which the wedge blocks "p and pl
are pushed outwards or withdrawn by means of the right and lefthanded screws
"o and o 1" attached to the wedge blocks.
"
In case of differences of pressure on either end of the cylinder, this may
be adjusted by the adjusting screws
k and k 1." The final adjustment according
to the variation in the material to be treated is automatically effected by the
springs " and i 1."
The cylinders "A and B" are geared together by ordinary gear wheels. In front
of the cylinders "A and B" is fitted a table, see Figure 1, which automatically
adjusts itself according to the position of the adjustable cylinder by the carrying
bars "," Figure 1 to which the table is fixed. The carrying bars rest with the
one end on the box bearings "g and g 1" and are hinged to the crossbar “8” at the
foremost end of the frame.
"

In the centre of the table is fitted a slide "t" which is connected to a lever " 33
this is connected to a box rod "v" which carries a roller "v1" which works on a
cam "w" which is bolted to an adjusting collar "w1"; this is keyed to the shaft
of the cylinder "B."
On the slide "t" is bolted an adjustable plate "x "to which a piece of wood may
be fitted suitably shaped to suit the class of work to be done, such as barrel
heads etc.
The feeding slide "t" is held back by the action of the cam in connection with
the lever."u" and the box rod "v." When the cam releases the lever the slide “t”
is pulled forward by the springs "y and y 1" and by this the material is fed in
between the cylinders "A and B."
The spring "y1" acting on the lever "u" and the spring "y" connects the
lever "u" and the feeding slide "t."
The ductor roller "e" is operated by an adjustable disc and an ordinary ratchet
as shown at "&" Figure 2 and Figure 5.
Motion is given to the machine by pulleys fixed to a shaft carrying a pinion.
This pinion works in a spur wheel which is keyed to the shaft of the
cylinder "B,"
The gear wheels are indicated in Figure 1 by dotted lines.
The corresponding letters in the different figures refer to the same part or parts
of the machine.
Figure 1, is a side view of the machine.
Figure 2, is a plan of the machine, with the roller "d4" removed. .
Figure 3, is a partial cross-section.
Figure 4, is a view of the box rod and cam for feeding arrangement.
Figure 5, shows the adjustable disc and ratchet by which the ductor roller is
worked.
Figure 6, is an end view of the cylinder "A" with the cam and the vibrating
roller with its frame and counter-weight.
Figure 7, is a view of the fork and crank by which the two inking rollers
"d3 and d 4" receive the reciprocating motion.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
:-
