Improvements in Wood-printing Machines.
I SIMEON LORD of 5 Bow Common Lane, in County of Middlesex, Engineer, do
hereby declare the nature of this invention to be as follows :-
My invention relates to that class of printing machines which are employed for
printing names of persons and goods or other matter upon lengths of wood previous
to their being made up into boxes, and the object of my invention is firstly to
enable the position of the type upon the printing cylinder to be more readily and
accurately adjusted in relation to the varying sizes of the lengths of wood to be printed
upon and thereby facilitate printing in two or more colours and secondly to enable the
lengths of wood to be fed to the machine in a more efficient manner than heretofore.
In carrying out the first part of my invention I mount the toothed wheel through
which motion is given to the printing roller loosely upon the shaft or axis thereof and
I fix this wheel in relation to its shaft or axis at the desired times by means of a
locking or clamping device or clutch keyed upon the shaft or axis of the printing
cylinder.
This clamping device consists preferably of a disc or arms through the extremities
of which are passed threaded bolts which are acted upon by nuts taking an abutment
upon the face of the disc or arms and the heads of the bolts are formed dovetailed to
fit and travel in a corresponding annular groove formed in the face of the toothed
wheel.
By these means the toothed wheel may by unscrewing the nuts be disconnected
with the shaft or axis of the printing cylinder when such cylinder may be revolved
to the desired position and again connected with the shaft or axis of the printing
cylinder by screwing up the nuts and thus the position of the type in relation
to the length of wood to be printed upon may be adjusted with the greatest
precision.
Or I may employ any other suitable form of clamping device or clutch capable of
readily connecting and disconnecting the toothed wheel with the shaft or axis of the
printing cylinder and admitting of the necessary fine adjustment of the parts in relation
to each other.
If preferred I may fix the toothed wheel upon the shaft of the printing cylinder
and mount the type upon a cylindrical frame encasing the type roller or cylinder
with capability of being revolved independently thereof and fixed in any desired
position in relation thereto.
In carrying out the second part of my invention I cause the sliding feed plate or
pusher to follow the length of wood right up so that in the event of the ordinary roller
feed failing in consequence of the introduction of a length of wood of less substance
than the machine has been set to feed the feed plate will still carry the length of wood
through the machine.
For this purpose I connect the sliding feed plate or pusher by means of a pin joint
with a pusher rod which passes through with capability of being fixed in a boss
formed on or carried by one end of a pusher lever the other end of which is mounted
upon a centre of motion carried by a bracket from the frame of the machine, or a
separate short standard fixed to the bed plate or floor.
The boss at the upper end of this pusher lever is provided with a set screw by
means of which the pusher rod may be fixed in any desired position in relation thereto
and the pusher lever is slotted for part of its length to give adjustment to one end of
a connecting rod which works upon a pin capable of being fixed at any desired position
in the said slot.

page_text: The other end of this connecting rod is pin jointed to one end of a rocking lever
which is mounted upon a centre of motion upon the frame of the machine and the
other end of this rocking lever is connected by pin joint with one end of a connecting
rod the other end of which is mounted upon a stud fixed eccentrically in the face of
one of the wheels of the machine.
By these means the position of the point of connection of the connecting rod with
the pusher lever and the consequent relation of such point to the axis of such lever may
be varied and thus the degree of motion imparted to the feed plate through the pusher
lever and pusher rod may be regulated at will.
In lieu of a single pusher lever I sometimes employ a suitable arrangement of levers
and links forming a parallel motion and thereby ensure the regular movement of the
feed plate or pusher.

Improvements in Wood-printing Machines.
I SIMEON LORD of 5 Bow Common Lane in the County of Middlesex, Engineer
.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 relates to that class of printing machines which are employed for
printing names of persons and goods or other matter upon lengths of wood previous
to their being made up into boxes and the object of my invention is firstly to enable
the position of the type upon the printing cylinder to be more readily and accurately
adjusted in relation to the varying sizes of the lengths of wood to be printed upon and
thereby facilitate printing in two or more colours and secondly to enable the lengths
of wood to be fed to the machine in a more efficient manner than heretofore.
In carrying out the first part of my invention I mount the toothed wheel through
which motion is given to the printing roller loosely upon the shaft or axis thereof and
I fix this wheel in relation to its shaft or axis at the desired times by means of a
locking or clamping device or clutch keyed upon the shaft or axis of the printing
cylinder.
This clamping device consists preferably of a disc or arms through the extremities
of which are passed threaded bolts which are acted upon by nuts taking an abutment
upon the face of the disc or arms and the heads of the bolts are formed dovetailed to
fit and travel in a corresponding annular groove formed in the face of the toothed
wheel.
By these means the toothed wheel may by unscrewing the nuts be disconnected with
the shaft or axis of the printing cylinder when such cylinder may be revolved to the
desired position and the toothed wheel again connected with the shaft or axis of the
printing cylinder by screwing up the nuts and thus the position of the type in relation
to the lengths of wood to be printed upon may be adjusted with the greatest
precision.
Or I may employ any other suitable form of clamping device or clutch capable of
readily connecting and disconnecting the toothed wheel with the shaft or axis of the
printing cylinder and admitting of the necessary fine adjustment of the parts in
relation to each other.
If preferred I may fix the toothed wheel upon the shaft of the printing cylinder
and mount the type upon a cylindrical frame encasing the type roller or cylinder
with capability of being revolved independently thereof and fixed in any desired
position in relation thereto.
In carrying out the second part of my invention I cause the sliding feed plate or
pusher to follow the length of wood right up so that in the event of the ordinary

. In the several figures like parts are indicated by similar letters of reference.
As the general features of the machine are well known and fully described in the
specification of Letters Patent granted to William Robert Lake dated the 1st day of
September 1880 No. 3547 I will only refer to such parts thereof as are intimately
connected with my improvements.
a represents the frame of the machine b represents the main shaft c represents the
under or platen cylinder and d represents the printing or type cylinder.
The main shaft 6 is mounted in bearings a carried by the frame a and provided
with fast and loose pulleys 6¹ upon one end thereof through which it is driven by
means of a belt from any convenient source of power and upon the same end of the
main shaft 6 is fixed a pinion b which gears with a toothed wheel c fixed upon that
end of the shaft c¹ of the platen cylinder c and motion is thus given to such cylinder.
Upon the opposite end of the shaft c¹ of the platen cylinder c is fixed a toothed
wheel which gears into a toothed wheel c' mounted upon a stud of fixed to the frame

page_text: of the machine and the toothed wheel c¹ gears into a similar toothed wheel c³ mounted
upon a similar stud c and the toothed wheel e gears into a toothed wheel d' adjustably
fixed upon the shaft d¹ of the printing cylinder d and motion is thus given to such
cylinder.
According to the first part of my invention I mount the toothed wheel d' through
which motion is given to the printing cylinder d loosely upon the shaft or axis d'
thereof and I fix this wheel d in relation to its shaft or axis at the desired times by
means of a locking or clamping device or clutch keyed upon the shaft or axis d¹
of the printing cylinder d.
Referring to Figures 1 to 6 the clutch or clamping device consists of two arms or
a portion of a disc e which is fixed upon the shaft d' of the printing cylinder d by
means of a key e' held in place by a collar e and set screw e³.
Through holes formed in the extremities of the arms e are passed threaded bolts e
upon which are screwed threaded nuts e taking an abutment against the face of the
arms e and the heads e of the bolts et are formed dovetailed to fit and travel in a
corresponding annular groove & formed in the toothed wheel da hole or way d
being provided through the back of the wheel to the groove ³ to allow of the
insertion of the bolts et into position.
By these means the toothed wheel & may by simply unscrewing or loosening the
nuts and without the necessity of moving the disc or arms e endwise upon the
shaft d¹ be disconnected with the shaft or axis d' of the printing cylinder d when such
cylinder may be revolved independently of the toothed wheel d in order to bring the
type plate d and type de into the desired position after which the toothed wheel d'
may be again connected with the shaft or axis d¹ of the printing cylinder d by
screwing up the nuts e and thus the position of the type de in relation to the length
of wood to be printed upon may be adjusted with the greatest precision.
I would have it understood that I do not confine myself to the precise arrange-
ment of parts herein before described as it is evident that I may employ any other
suitable form of clamping device or clutch capable of readily connecting and dis-
connecting the toothed wheel d with the shaft or axis d' of the printing cylinder
and admitting of the necessary fine adjustment of the parts in relation to each other.
I am aware that it has heretofore been proposed to form the toothed wheel d' with
a ring of holes in the face thereof and the arms e with corresponding pins or studs in
order to adjustably connect the printing cylinder with the toothed wheel the arms
in this case sliding in and out of engagement upon a feather upon the shaft d¹ but
such contrivance gave only a very coarse adjustment defined by the distance apart
of the holes in the toothed wheel and was difficult of manipulation whereas by means
of my invention I am enabled to obtain the finest possible adjustment with great
facility.
I am also aware that it has been proposed to employ a disc or arms sliding upon a
feather upon the shaft d' of the printing cylinder d and provided with a ring of teeth
upon the inner face thereof engaging a corresponding ring of teeth upon the outer
face of the toothed wheel but this arrangement also possesses the defects pointed
out with regard to the arrangement lastly hereinbefore referred to.
According to the arrangement represented at Figures 8 and 9 I fix the toothed
wheel dupon the shaft or axis d¹ of the printing cylinder d and mount the type
plate upon a semi-cylindrical frame d' partially encasing the printing cylinder d
with capability of independent revolution in relation thereto.
The semi-cylindrical frame or casing d' is at each end thereof mounted with
capability of revolution upon the shaft or axis d¹ of the printing cylinder d and has
fixed upon one end thereof a worm wheel d³ which engages a worm d carried by a
bracket d fixed on the shaft or axis d' of the printing cylinder d and which worm d
is provided with a square do to receive a key by means of which it may be rotated.
By rotating the worm d the semi-cylindrical frame or casing d together with the
type plate d may be revolved independently of the printing cylinder d and adjusted
to any desired position in relation thereto the worm wheel do and worm & forming an
efficient lock to fix it against accidental revolution.

page_text: Or in lieu of the worm wheel & and worm dany other suitable means may be
employed to attain the desired end.
The type plate d is fixed upon the printing cylinder d or casing d' by means of
screws and a filling plate d of similar thickness and meeting the type plate d³ is
similarly fixed thereon in order to render the acting part of the printing cylinder d
of one uniform diameter and thus enable it to obtain an efficient grip of the length
of wood to be printed upon and also to act as a stop or support to the type
plate d³.
In wood printing machines as heretofore constructed the sliding feed plate g has
been caused to deliver the lengths of wood f to be printed upon one at a time into the
grip of the cylinders or rollers cd the cylinder d being fitted with rings to grip the
wood and feed it forward and as the successful working of the machine has been
dependent upon such rings obtaining a proper grip of the length of wood it not
infrequently happened and more especially when printing upon two lengths of wood
placed side by side that in consequence of the introduction of a length of wood of less
substance than the machine was set to feed or of two lengths of unequal substance such.
thin length of wood was not properly carried through the machine and this resulted
in very imperfect printing.
Now according to the second part of my invention I give the sliding feed plate or
pusher g a greater range of motion than heretofore and thus cause it to follow the
length of wood fright up so that in the event of the ordinary roller feed failing the
feed plate or pusher g will still carry the length of wood through the machine.
For this purpose I form on or fix to the sliding feed plate or pusher ga descending
bracket g and I connect to this bracket by means of a pin joint gone end of a
pusher rod h which passes freely through a boss mounted with capability of
oscillation upon centres of motion carried by the forked upper end of a pusher
lever whilst the lower end of the pusher lever i is mounted with capability of
oscillation upon a centre of motion carried by a bracket or short standard a fixed
to the bed plate or floor.
The boss is capable of being fixed in relation to the pusher rod h by means of
collars and washers is the collars being held in place by set screws in order
to admit of the necessary adjustment of the boss upon the pusher rod h and in
relation to the feed plate g whilst between the washer and the boss i¹ a spring i is
interposed for the purpose hereinafter explained.
The pusher lever i is provided with a number of regulating screw holes iⓇ therein
adapted to afford adjustment to one end of a connecting rod ; which works upon a
pincapable of being screwed into and thus fixed in any one of such holes or in
lieu of the screw holes a long slot might be employed and the pin might be
clamped in position by means of a nut screwing upon the end thereof which in that
case should extend through the slot and project upon the opposite side of the pusher
lever i.
The other end of the connecting rod j is at pinjointed to the end of a lever k
which is fixed upon a rock shaft k* working in bearings in the frame a of the machine
and another lever k¹ also fixed upon the rock shaft is provided with a slot k³ in
which is adjustably fixed a pin upon which is mounted one end of a connecting
rod the other end of which is mounted loosely upon a stud e fixed eccentrically in
the face of the toothed wheel c so that as the toothed wheel c* rotates in the operation
of the machine a to and fro motion will thereby be communicated to the pusher
lever i and feed plate or pusher g.
By these means the position of the point of connection of the connecting rod j with
the pusher lever i and the consequent relation of such point to the axis of such
lever i may he varied and thus the degree of motion imparted to the feed plate g
through the pusher lever i and pusher rod may be regulated at will but I so
arrange the extent of traverse given to the feed plate gas to carry the length of
wood through the machine until the type has completed the printing and moved
clear thereof.
As the motion imparted by these means to the pusher rod is not sufficiently

page_text: C
regular to correspond at all points of its traverse with the surface speed of the
cylinders c and d I interpose the spring between the pusher lever i and the pusher
rod h in order to take up and give out any excess of motion and thus compensate to
some extent for such irregularity.
According to the arrangement represented at Figure 10 the end of the connecting
rod j is forked and mounted upon the ends of a pin j¹ fixed in a block j* sliding in a
vertical slot formed in the pusher lever i and a link ¿¹0 at one end mounted upon the
pin and at the other end upon a centre of motion controls the position of the
point of connection of the connecting rod with the pusher lever i and thereby further
assists to render the action of the feed plate g more regular.
In lieu of giving motion to the pusher lever i through connections from an
eccentric pin c in the toothed wheel c 1 may if desired employ an eccentric and strap
or a cam in order to obtain such motion as will be readily understood.
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 r
claim is.
