Improvements in Machinery for Printing or Stamping Advertisements
or Names on the Outside of Pencils and Pen Holders.
THOMAS EDWIN EDWARDS, 26ª City Buildings CHARLES KEIZER, CHARLES
WILLIAM KEIGHLEY, 18 Regent Road, Engineers, and ALBERT TOMLINSON WRIGHT,
17 Water Street Solicitor, all of Liverpool, 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 machinery for printing or stamping advertisements or
names longitudinally upon the outside of pencils, and the like, constructed in such a
manner that a number of pencils can be placed in a round rack or holder which is
arranged to be intermittently revolved on a table.
In the table is a hole in the path of the pencils, through which the pencils fall one
at a time as the rack revolves, and are caught and carried down to a printing chamber,
to be printed on their surface, and after being printed fall out; or in place of the
pencil holder being placed above the printing chamber; it may be arranged under it
and the pencils gripped and drawn up into the printing chamber, the whole of the
operations necessary for the carrying out of the above being performed continuously
and actuated from the main driving shaft, which is proposed to be driven by power
in any usual manner.
To enable our invention to be properly understood we will proceed to fully describe
the same with aid of the accompanying drawings.

This
A, are the pencils held in a rack composed of three discs A¹ A* A* having a ring
of suitable holes near their edge for the pencils to pass through these discs are held
and revolve upon a vertical stem A projecting from a table B, connected to the
frame C, of the machine, upon this table the bottom disc A lays and revolves.
disc has ratchet teeth on its periphery, to enable the rack to be intermittently rotated
by means of a spring pawl D, passing through a guide in stud D' and pivotted to a
pivotted lever D2 which is pivotted to rod D³ connected to an eccentric worked by
driving shaft E, of machine. This shaft is revolved by a gear wheel E¹, gearing with

page_text: a pinion E on main driving shaft E. Through the table B, is an opening or hole F,
made in the path of the pencils through which a pencil falls at each movement of the
rack and into a receiving tube G, held under table B and true with hole F. This
receiving tube is carried at its other end by a sliding cross-head G', moving moving on
vertical guide rods G' the lower end of this tube extends into the printing chamber H,
through the cover H. Over the tube G is a sleeve tube G³ having upper and lower
collars G G. Round this tube G³ inking composition is cast thus forming an inking
roller which is free to revolve on tube G." This roller is fed with ink in the usual way
from a ductor and distributing rollers (not shown in drawings). At the end of the
tube G, are pivotted two pendant hooks I having one of the upper corners I¹ cut off
to form angle flats for the bottom collar G to rest upon when in the position shown
by dotted lines in fig. 6, and to enable the hooks to be held apart while the tubes G, G³
and G are moving up out of the printing chamber, to the position shown in fig. 3.
The inking roller tube G is capable of a slight longitudinal motion on the tube G
which allows the pendant hooks I, I, to be readily opened or closed. The inking
roller tube is kept pressed on top of the hooks by means of the coiled spring K
Figure 6.
When a pencil drops into the tube G, it rests upon the points of the hooks I,
and is so carried down into the printing chamber II, by the downward movement of
the tube and is there released by the spreading of the hooks when they come upon
the tapered outside of the exit nozzle J, as is shown by dotted lines in fig. 6. The
tube G, with pencil inside after it has been let down by means that will be hereafter
described into the printing chamber H, ascends as soon as the pencil has been
released, and to prevent the points of the hooks from taking hold of the pencil the
hooks are held apart by the collar G of the tubes, resting upon the angle flats 1' the
hooks are drawn into their normal position by passing through the hole in cover l'
ready to support the next pencil that falls into the tube. The receiving tube G is
operated as follows: The cross-head G' is connected by a link K, to one end of a lever
arm K the latter being pivotted at its other end to the frame-work of machine.
The lever arm K is formed with a yoke K2 having projecting flanges K³ on outside;
in the yoke K² is a curved slot K through which passes the working shaft E, carrying
a cam K which acts between the flanges K to operate the lever arm K and
consequently giving the tube G. an up and down movement with periods of rest at the
top and bottom of its stroke; When the tube G and the parts it carries are in the
position shown at figures 2 and 3, the pencil rack is rotated a step to enable a pencil
to fall through the hole F, into tube G. Referring to figures 4 and 7 L are the
printing dies carried in die plates L' working in slots or guides L in top H' and
bottom H2 of chamber H, towards the centre by a partial rotation of the chamber H,
by the swinging arms L³ passing through side of chamber H, forcing the die plates L',
towards the centre. These swinging arins Ls are connected to a pivotted support L
held by points Le (fig. 7). On the shaft E, is a cam O, having on its periphery a
recess 0³, and a notch O and a side stud 0. The periphery of the cam O acts upon
a side stud N', attached to the pivotted lever N, and the side stud 08 upon the top of
lever N, which operates the inking of the dies and the printing as follows:-
Attached to the lover N, is a rod P, suitably guided and having a rack P¹ near bottom
this gears with a pinion P2 on short shaft Ps carrying a bevel wheel R, at its other
end which gears with a rack S, attached to the side of chamber H. When the tube G,
and its accessories are at the bottom of their stroke, that is in the printing chamber
the notch O' on the cam O, comes over the side stud N on lever N. and the weight M,
falls a short distance rotating the printing chamber and pressing the dies on to the
inking roller. The weight is then lifted to its highest position by the periphery of
the cam O, the inking roller and tube are raised out of the printing chamber, leaving
a pencil behind. As soon as the tube G, and its accessories are clear of the dios, the
notch O, of cam O, allows the side stud N' of lever N, to fall in, thereby enabling
the weight M, to force down the rod P, which partially rotates the chamber H, as
described and pressing the inked dies on to the surface of the pencil, the weight M,

page_text: ·being again lifted, and held by the side stud 0³, until the periphery of the cam O,
comes upon the side stud N. After the printing the pencil is let out through the
outlet nozzle J, by the sliding forward of the door J¹ actuated by the bell crank
lever Joperated by a trigger catch J' on bottom of rod P.
By reference to fig. 4 it will be seen that the arrangement shows six dies so that a
pencil can receive simultaneously six longitudinal impressions or printings on its
surface. If desired a less or larger number of dies could be arranged.
The travel of the dies L, are provided for to suit pencils of different diameter, by the
adjusting nuts L'.
It is found in the printing of flat sided pencils that it is advisable to secure the
pencils after it is left in the printing chamber, so as to hold it with the flat sides
truly facing the dies, for this purpose the arrangement shown in figures 9, 10, 11,
is used, this consists of two sliding rectangular shaped plates, sliding in a
dove-tail groove, Y, in plate Y having projecting pegs which pass through
curved slots 22 in plate X, the partial rotation of the plate X in the direction of
the arrow, by the rod X brings the ends of the plates %, towards each other by
means of the curve slots acting upon pegs Z thereby gripping the bottom of
the pencil under J; the plate X is connected to a rod V attached to a spiral spring V
the free end of which is bent at right angles to be caught by the triggor V2 to hold the
plate sufficiently long to secure the pencil while being printed.
This trigger is then lifted by the downward movement of rod P' by the side
stud P when the plate X is drawn back to its normal position by means of the spiral
spring V, which causes the two. plates % to be moved back, thereby releasing the pencil
and allowing it to drop out on the forward movement of the door J¹.
To assist this rest to be given to plate X the rod X' is connected to it by a slot the
rod being operated by the crank on shaft. In place of the pencil rack being at the
top of the machine making it advisable to use the pencil gripping device, illustrated at
figures 9. 10. 11. The pencil rack may be placed under the printing chamber, and
the pencils pulled up into the printing chamber, and after printing drop out as before
described. The arrangement to enable this to be done, is illustrated at figures 12. 13.
14. 15. 16. The pencil holder or rack shown in these figures is composed of a top
dise a middle disc and a bottom C³ the latter being attached to the tube
pedestal this rack is carried on central pin or pivot D on a sliding plate. B' which
is moved to bring the pencils in a line under the tube G, to enable nippers G at end
of this tube to grasp a pencil. The manner of working of the arrangement shown at
these figures is as follows: The spiral spring A' is first unhooked and the sliding
plate B drawn out a pencil rack full of pencils is put on the central pin or pivot. D' on
which the rack revolves, this plate 13 with the rack full of pencils is then pushed back,
and the spiral spring A re-connected. This plate B has a reciprocating movement
given it by a bell crank lever E3 pivotted to the side frame, having a side arm E
which engages bottom of pin 14 and the spiral spring A. The lever E³ is actuated
by the bottom end of rod P pressing on the arm E as the rod P, descends.
The nippers G7 at the bottom of the tube G are kept closed by an india rubber
ring or other suitable spring G and are opened by means of the small double
cam H³ (fig. 13) on the bottom of a rod H passing down the inside of tube G.
This rod His partially revolved in one direction by means of the lover J' operated
in one direction by connecting rod (K') hell-crank K and notched cam: 0*, secured on
shaft E, (fig. 15) and in the other direction by the spiral spring №2. A key way
is cut on the upper part of rod H to engage a key I' fixed in lever J' so that
the rod H may be free to slide up and down as the inking roller is raised or
lowered.
Suppose a pencil to have been drawn up into printing chamber H, the weight M,
falls operating the parts to stamp the pencils as has been described, and the bottoni
of rod P, presses down arm of lever moving the sliding plate B¹ by the
arm E. Directly this takes place, the point 0' of periphery of cam O' passes the
side bearing stud K³ on lever K7, the lever is drawn into the position shown by

page_text: dotted lines by the spring N partially turning the rod H to open the nippers G³
by the action of the double cam 11 on end of rod H so that the pencil falls out.
The weight M previously described is now being raised-an the spring A draws
the sliding plate B' back. On the backward movement of the plate B₁ the pawl Fª
engages the ratchet teeth A moving the rack one step and bringing a fresh pencil
under the centre of the machine to be gripped and drawn up into printing chamber as
described. When the weight M, is up the inking roller descends as before described
the nippers G7 being held open by the cam H³ till they are over the pencil when the
side stud on cam O engages the lever (K) and moves it into the position shown in
drawing, thereby turning the rod El and cam H and allowing the nippers G7 to close
on the pencil. The holes in the pencil rack for the pencils to pass through to be
held can be made of the form to correspond with the sides of the pencils so as to keep
them from turning to enable them to be properly drawn into the printing chamber to
be stamped on their flat sides.
When round pencils are being stamped, the turning in the rack is in material.
