We, ELLIS GRABER, of 9, Hollybank Terrace, Tunbridge Wells, in the County
of Kent, Machine Ruler, and LEWIS HEPWORTHI, of 16, Beltring Road, in the
town and county aforesaid, Master Printer, do hereby declare the nature of this
invention to be as follows:
-
This invention relates to an improved construction of that type of ruling
machine set forth in our prior Patent No. 11858 of 1894, and it consists of cer-
tain improvements hereinafter more particularly specified whereby the machine
is made more perfect.
According to this invention motion is imparted to the reciprocating and rotat-
ing tables by means of power gear which consists essentially of a shaft mounted
in suitable bearings and adapted to receive motion from any convenient source
of power, of a second shaft geared with the first axle by means of spur gearing
and of a main shaft adapted to operate the reciprocating and rotating tables,
the said main shaft being driven from the second shaft by means of a strap
The driving
and coned pulleys so that its speed may be varied as desired.
motion is imparted from the first shaft to the spur gearing by means of a cone
or other suitable clutch operated by a treadle lever so that the machine can be
instantly started and stopped..
Instead of mounting the stops or cams for lifting the pen beam on the recipro-
cating or rotating tables they are mounted on the main shaft, and as this shaft
is speeded to give one revolution for each reciprocating or revolution of the table
as the case may be, a cam is used for controlling the fall of the pen beam instead
of a fly or its equivalent.
Motion is imparted to the reciprocating table from the main shaft in the fol-
lowing manner: On the main shaft is a disc face cam adapted to impart motion
to a rocking quadrant by means of a suitable link, the cam being such that it
gives a quick return to the table and a pause at the termination of each travel
of the table before its motion is reversed. The rocking quadrant carries a rack
which gears with a fast and loose pinion on an axle extending across the width of
the machine. On this axle is mounted a drum round which and round an idle
pulley or drum at the front end of the machine and over a suitable tensioning
pulley or drum is a band or belt preferably of the positive driving type. This
belt passes through a hole in a bracket fixed to the underside of the reciproca-
ting table and is adapted to be clamped therein to lock the table to it in any
desired position by means of an eccentric or cam locking device operated from
the front end of the table. The link conveying the motion from the cam on the

page_text: main axle to the rocking quadrant is adjustably connected to the said quadrant
so that the arc through which it moves can be varied according to the length of
travel it is desired to give to the reciprocating table.
Motion is imparted to the rotating table from the main shaft in the follow-
ing manner: On the main shaft is a spur wheel which gears with a spur pinion
on a short axle mounted transversely on the frame carrying the rotating table
which axle gears with the vertical axle of the said table by means of bevel gear-
ing. A certain number of teeth of the spur wheel on the main shaft are cut
off or omitted for the purpose of giving the table a pause at the end of each
revolution and the number of the remaining teeth is such that one revolution
of the main axle causes the rotating table to travel slightly more than a com-
plete revolution so as to ensure making a perfect joint of the lines of circles and
other figures. During the pause the table is caused to rotate backwards just
the amount it has travelled over the complete revolution by means of a bell
crank lever actuated by a cam on the main shaft and acting on the table through
an adjustable projecting piece thereon which also on the backward rotation
of the table comes into contact with a stop carried by the frame of table, the
construction being such that the stop allows the projecting piece on the table
to pass by it when the table is rotating in a forward direction. To check the
momentum of the rotating table just before it reaches the end of its rotation a
brake preferably of the strap and drum type is employed on the intermediate
axle the brake being put into operation by a suitable cam on the main shaft.
When the rotating table is in use the fast and loose pinions on the second axle
for imparting motion to the reciprocating table is disengaged so that the said
axle receives no motion from the rocking quadrant.
The arm operating the device for controlling the flow of ink from the reser-
voirs to the pens is operated by an adjustable cam on the main axle through
suitable connections, the construction being such that the ink can be caused
to flow or cease at any part of the travel or rotation of the table.
To enable wavy or sinuous lines and polysided or figures of a shape other than
round oval or the like we mount the pen slide in the pen beam so that it is free
to move transversely therein, motion being imparted to the said slide in the fol-
lowing manner --In suitable bearings at the rear of the pen beam is mounted
a transverse slide which carries a pin adapted to engage with a vertical slot
in a light frame connected to the pen slide so that while the said slide causes
the pen slide to partake of its oscillations the beam carrying the pen is free to
rock on its pirots. Motion is imparted to this slide from an axle mounted at
right angles to it by means of a disc carrying an adjustable crank pin which
carries a block adapted to engage with a transverse slot formed in an enlarge-
ment in the said slide. Motion is imparted to the axle carrying the crank disc 4
from the second axle for imparting motion to the reciprocating table through
any suitable train of gearing which will give any desired number of recipro-
cations to the pen slide during one reciprocation or rotation of the table as the
case may be. When this device is used with the rotating table motion is imparted
to the second axle from the intermediate axle of the rotating table through a 4
suitably arranged axle and bevel gearing.
In order to facilitate the removal of the sheets of paper after they have been
ruled we use a wiper for lifting one corner of the top sheet of the pile imme-
diately the ruling is finished and just before the paper grippers lift. This wiper
is operated by a cam on the main shaft through suitable mechanism, and with 5
it is used a finger adapted to engage with the next sheet of the pile immediately
the corner of the top sheet is lifted and to hold it firmly until the grippers again
engage with the sheets of paper.
The paper grippers and the stencil holder are operated by means of a rising
and falling bar arranged along the side of the machine and having a parallel 54
motion imparted to it by means of a cam on the main shaft, the said bar operat-
ing the grippers and stencil holder through the medium of a curved lever,

page_text: thus providing for their operation whatever the length of the travel of the
table may be without any further adjustment.

Improvements in and relating to Ruling Machines.
We, ELLIS GRADER, of 9, Hollybank Terrace, Tunbridge Wells, in the County
of Kent, Machine Ruler, and LEWIS HEPWORTH, of 16, Beltring Road, in the
town and county aforesaid, Master Printer, 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 improvements in that type of ruling machine set
forth in our prior Patents Nos. 11858 of 1894, and 5394 of 1895..
In order that our said invention and the manner of carrying the same into
practical effect may be fully understood we will more particularly describe it
making reference to the accompanying drawings in which Figure 1 Sheet

Throughout the views similar parts are marked with like letters of reference.
According to the present invention motion is imparted to the reciprocating and
revoluble tables X and X', respectively by means of power gear instead of by

page_text: hand. Mounted in suitable bearings carried by the frame of the machine is a
shaft 1 on which is fixed a pulley to which motion is imparted by means of
a belt from any convenient source of power. On the shaft 1' is loosely mounted
a spur pinion 2 which gears with a spur wheel 3 on a second shaft 4, which
shaft communicates motion to the main shaft 5 which carries the operating
mechanism for imparting motion to the reciprocating and rotating tables by
means of coned pulleys 6 and 6" and a driving belt as shown whereby its speed
of rotation may be varied. The spur pinion 2 on the shaft 1 is coupled to the
said shaft when it is desired to set the machine in motion by means of any suit-
able form of clutch 7 brought into action from the front end of the machine by
means of a treadle lever 8 carried by a rocking shaft 8ª mounted in suitable
bearings in the frame. The rear end of the treadle lever 8 is connected with a
second rocking shaft 9 by means of a link 9" and the rocking shaft is connected
with the clutch 7 by means of the usual forked lever 10. The clutch 7 is con-
trolled by any suitable spring to withdraw it from the spur pinion 2 immediately
the foot is removed from the treadle 8. To enable the machine to be run without
the operator continually keeping his foot on the treadle 8 the rocking shaft 8
is capable of being operated and locked in position by means of lever 10 pivotted
to the frame and connected with the said rocking shaft by levers 10°, 10° and
connecting link 11 as shown by Figures 1 and 8.
The pen beam A is lifted i.e. rocked on its pivot a by means of one or more
cams 12 carried by a disc 13 on the main shaft 5. This cam acts on the striker
14 connected to the pen beam A by clutch mechanism A' as specified in our
prior Patent No. 5394 of 1895 through the medium of a lever 15 pivotted to the
frame of the machine and connected with the striker 14 by a link 16. As the
shaft 5 is speeded to revolve once for each reciprocation or rotation of the table,
as the case may be, the fall of the pen beam as well as the lift thereof is con-
trolled by the cam 12 to which end the cam is so shaped as to keep the pen
beam lifted during the required period.
Motion is imparted to the reciprocating table X from the main shaft 5 in
the following manner:-On the main shaft 5 on the opposite side of the machine
to the cam disc 13 and coned pulley 6 is a face cam 20 adapted to impart motion
to a rocking quadrant 21 pivotted at 22 to the frame of the machine by means
of a link 23, the cam being such that it gives a quicker movement to the quad-
rant in one direction than the other and a slight pause at each end of the stroke
before its motion is reversed. The link 23 carries a roller 24 with which engages
the groove 20 of the cam 20 and it is guided at its forward end by a slot 25 in
it engaging with the shaft 5. The other end of the link 23 is connected to
the quadrant 21 by means of a stud pin 26 the position of which is adjustable
in a slot 27 in the quadrant so that the point of connection of the link may
be varied to give the reciprocating table X any desired length of travel. The
rocking quadrant preferably has an extension arm 17 carrying a weight 18 to
balance it. The face of the quadrant 21 carries a rack 28 which gears with a
pinion 29 loosely mounted on a shaft 30 carried in suitable bearings on the
frame of the machine. This pinion 29 is capable of being connected to the shaft
30 carrying it by means of any suitable form of clutch. On the shaft 30 is
fixed a drum 31 round which and round an idle pulley or drum 32 at the front
end of the machine and over a suitable guide pulley or drum 33 mounted near
the periphery of the drum 31 is a band 34 of any suitable type but preferably
of the positive driving type. The band 34 passes through a elot 35 in a bracket
36 fixed to the underside of the reciprocating table X and is adapted to be
clamped therein to lock the table to it in any desired position by means of a
gripping piece 37 guided in the bracket 36 and acted upon by an eccentric 38.
This eccentric is mounted on a shaft 39 which extends to the front end of the
machine where it carries a lever 40 or its equivalent whereby it can be rotated
to actuate the eccentric gripping device.
The nipping bar B of the device for controlling the flow of ink from the reser-

page_text: voirs to the pens as specified in our prior Patent No. 5394 of 1895 is operated
by a cam 43 adjustably mounted on a disc 44 fixed on the main axle 5 through
a lever 45 pivotted to the frame of the machine a link 46 connecting this lever
with another lever 47 pivotted at 48 to the frame of the machine the other end
of which lever engages with an arm 49 mounted on the rocking shaft 50 carry-
ing the nipping bar B and capable of sliding laterally thereon so that it can
be taken. out of engagement with the lever 47 when it is desired to entirely
stop the flow of ink. The necessary pressure on the nipping bar B is obtained
by means of a weight 51 adjustably mounted on an arm 52 carried by the said bar.
The arm or lever w operating the paper grippers w and the stencil holder-
when such is used-which are constructed as specified in our prior Patent
No. 8050 of 1896-are operated by means of a rising and falling bar 54 carried
by two arms or levers 55 and 56 pivotted to the side of the frame of the machine.
The arm or lever 55 carries a second lever 57 forming a bell crank lever. The
free end of this arm 57 carries a roller which engages with a cam 58 on the
main shaft 5 which is timed to operate the arm or lever w during the pause
of the table at the forward end of its travel. By this construction the movement
necessary to operate the grippers and the stencil holder is imparted to the arm
or lever wat whatever point the table stops at without any further adjustment.
The revoluble table consists essentially of two parts a platen or table X'
mounted on an underframe 101 which carries two studs 102 at points diametri-
cally opposite to one another, and a wheel-shaped frame 103 having two placed
diametrically opposite slots 103. The frame 103 carries a sleeve or hollow
axle 104 adapted to fit over a hollow stud axle 107 carried by a foundation
frame 106. This foundation frame carries also a ring shaped frame 108 having
a groove 109 the outer wall 110 of which is cut away for about half its circum-
ference. This ring shaped frame 108 has three bars 111 each having a slot 112
and it is attached to vertical pillars of foundation frame 106 by means of suit-
able screws or bolts passing through the said slots 112 which provide for the
ring shaped frame 108 being placed eccentric with the hollow stud axle 107 when
it is desired to give to the revoluble table the necessary movement to rule oval
elipses or polysided figures.
If the ring shaped frame 108 is placed concentric with the stud axle 107 as
shown in Figures 16 and 17 the revoluble table will simply rotate about the
centre of the stud axle 107 thus allowing for the ruling of circles or segments
thereof, but if the ring shaped frame 108 is moved so as to be placed eccentric
with the stud axle 107 the revoluble table will receive an elliptical movement
through the aggregate motion derived from the groove ring 108 the slots 103°
in the frame 103 and the studs 102 carried by the frame 101.
The sheets of paper may be held down on the revoluble table by hand but
are preferably secured by means of clamps 115 which may also serve to hold
the stencil for the purpose of masking the paper where a line is not to be ruled.
The clamps 115 are carried by studs 114 fixed in tubular sleeves 116 by means
of lock nuts 114 so that they may be turned in any direction. The sleeves 116
slide in suitable bearings 117 in the table and are connected by a flat bar 118
on the underside of the table. This bar 118 is operated to lift the clamps by a
rod 119 mounted in and passing through the centre of the stud axle 107. The
lower end of the rod 119 engages with the end of a lever 113 pivotted to the
frame of the machine and engaging with the periphery of a cam 120 mounted
on the main shaft 5 so that the rod 119 and with it the bar 118 carrying the
clamps is periodically raised, thus allowing the sheets of paper on the table to
be removed therefrom after being ruled.
.
1.
The clamps 115 are kept in contact with the sheets of paper on the table by
means of a spring controlled axle 121 engaging the bar 118 through a plate
arin 122. Motion is imparted to the revoluble table X. from the main
shaft 5 in the following manner:-On
shaft 5 is
spur wheel 78 which gears with a similar wheel 79 carried by an axle 80
to
the main
a

page_text: mounted in a suitable bearing 81 on the underframe 106 of the revoluble table.
On the axle 80 is a bevel wheel 82 which gears with a bevel wheel 105 on the
sleeve or hollow axle 104 of the frame 103 of the revoluble table. A certain
number of the teeth of the spur wheel 78 on the main shaft 5 are cut off or
omitted for the purpose of giving the table a pause at the end of each revolu-
tion and the number of the remaining teeth is such that one revolution of the
main axle 5 causes the revoluble table to travel slightly more than a complete
revolution so as to ensure making a perfect joint of the lines of circles and other
figures. During the pause the table is caused to rotate backwards just the
amount it has travelled over the complete revolution by means of a bell-crank
lever 84 pivotted to the frame 106, one arm of which is actuated by a cam 85 on
the main shaft 5 through a lever 85 pivotted to the frame of the machine and
the other engages with a projecting piece 86 on the frame 103 of the rotating
table. To stop the table at the desired point in its backward rotation a spring
controlled pawl 87 pivotted to a bracket 88 engages with the projecting piece 86,
the arrangement being such that the pawl 87 allows the projecting piece 86 on
the frame 103 to pass by it when the table is rotating in a forward direction.
To check the momentum of the revoluble table X just before it reaches the
end of its rotation a brake preferably of the shoe and drum type is employed
on the intermediate axle 80, the brake shoe SS or its equivalent being operated
to bring it into contact with the drum 83 on the axle 80 by a cam 89 on the
main shaft 5 acting through a lever 89 pivotted to the frame of the machine.
As a modification the axle 80 may be arranged vertically in which case it
would receive its motion from the main axle 5 by means of bevel wheels and
impart motion to the sleeve or hollow axle 104 by means of spur wheels. In
order to increase the speed at which the machine may be worked without pro-
ducing undue shocks to the table when starting the wheels 82 and 105 may be
made elliptical, the arrangement of the wheels being such as will give a slow
motion to the table at starting and stopping and an increased speed during the
other part of each revolution.
To enable wavy or sinuous lines and polysided or figures of a shape other than
round or oval to be ruled the gripping attachment of the pen beam A is slackened
to allow the pen slide D to slide or move transversely therein, motion being
imparted to the said slide in the following manner:-Beneath the pen beam A
is a light frame 60 the forward ends of which are fixed to the underside of the
pen slide by means of bolts or screws 60°. This frame is adapted to slide trans-
versely by means of suitable rollers 61, 61° on transverse bars 62 and 62ª carried
by the pen beam A. The rear end of this frame carries a stud 63 which engages
with a vertical slot 64 in a frame 65 forming part of the oscillating mechanism,
the arrangement being such that the pen beam A is free to rock on its pivot
at the same time that an oscillating movement is being given to the pen slide.
The frame 65 is carried by a bar 66 sliding in bearings carried by a transverse
frame 67 fixed to the frame of the machine. Motion is imparted to the sliding
bar 66 by means of a crank disc 68 the pin 682 of which carries a block 69 which
slides in a transverse slot 70 formed in an enlargement 66 of the sliding bar 66.
The crank disc 68 is mounted on an axle 71 which is geared to another axle 72 at
right angles to it by means of a pair of bevel wheels 73 and 74. The axle 72
receives its motion from the axle 30 through a train of spur gearing so arranged
that any
desired number of reciprocations can be imparted to the pen slide during
one reciprocation of the table X or rotation of the table X as the case may be.
A suitable train of gearing is that shown in Figures 12 and 13, Sheet No. 8
of the accompanying drawings. On the axle 72 is a group of spur wheels 90
so mounted as to be capable of being moved transversely thereon and locked
thereto by means of a set screw 91 or its equivalent. On the axle 30 is a spur
wheel 92 which gears with the smaller of a double spur wheel 93 mounted on
stud axle 94 carried by the frame of the machine. On this stud axle is pivotted
an arm 95 which carries a spur wheel 96 gearing with the larger of the double

page_text: spur wheel 93 and adapted to be put in gear with one or other of the group of
spur wheels 90 on the axle 72.
When the mechanism for imparting an oscillating movement to the pen slide
is used with the reciprocating table X motion is imparted to the axle 30 by fixing
the pinion 29 to it, but when the mechanism is used with the rotating table X¹
the shaft 30 receives its motion from the sleeve or hollow axle 104 of the
frame 103. carrying the said table by means of an axle 97 mounted in suitable
bearings 98 carried by the frame of the machine and carrying, at its forward
end a bevel wheel 99 gearing with a second bevel wheel 100 on the sleeve or
hollow axle 104 and at its rear end a bevel wheel 101 gearing with a similar
wheel 102 on the axle 30.
