Improvements in Feeding Gauges for Printing Machines.
I, WILLIAM ARTHUR WORRALL, of Clifton Lodge, Queen's Road, Watford,
Process Engraver, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in connection with feeding gauges for
use with printing machines, and has for its object to provide an arrangement
which will be suitable for cylinder, platten, lithograph and other machines, and
which will feed the paper accurately.
The gauge I propose to employ has a double action giving a movement from
the side towards the centre of the sheet and at the same time a pushing down
action towards the bottom gauge.
According to one arrangement an eccentric movement is employed, the eccentric
completely revolving or only turning through a part of a circle. A triangular
frame is employed one arm of which is provided with a slot and clamp or thumb
screw fitted to this slotted arm fastening the frame to the feeding board. On
the front of the frame a movable support carrying the gauge is fitted, this support
working on a screw pivot. The body of the gauge is carried by this support and
underneath this part a knife is placed having a curved rib at its rear side. This
curved rib and the front edge of the knife are placed eccentrically to the pivot,
and the curve may be of any suitable form preferably not circular.
The position
of the gauge and consequently the movement of the blade or knife is adjusted
by a long thumb screw passing through bearings in the support so that the gauge
can be moved to any required position with great accuracy, altering the eccentricity
and the movement imparted to the paper.
To operate the device a jointed arm or lever is employed pivoted at one end
to the rear part of the frame. The other end of the jointed arm is connected to
the head of the screw, and to operate the device a rod is employed fitted to the
arm close to the joint, this rod being connected to the finger rod of the machine
or other working part. On moving the rod up the two parts of the arm are drawn
together pulling over the gauge turning it round its pivot and causing the eccentric
to push the paper forward at the same time pressing it down towards the fixed
gauge.
According to a modification instead of employing a pivoted eccentric a sliding
gauge is employed. This sliding gauge is fitted to a pivoted segment. The frame,
which may be formed from a single straight arm is furnished with a triangular or
segmental termination to one end of which the adjustable segment or aran is
pivoted. The adjustable arm is provided with a curved extension concentric with
the pivot, this portion being slotted and furnished with a thumb screw by which
the arm can be secured to the frame. Owing to the slot the arm can be fixed at
any desired angle. The gauge and knife bear on the side of the arm, and slide
upon the edge, the gauge being connected to the frame by a spring which will
withdraw it to its uppermost position when released. The rod pulls the gauge
down, this action moving the paper in the same manner as the eccentric above

page_text: described, and the extent of the motion can be accurately regulated by the position
of the arm.

Improvements in Feeding Gauges for Printing Machines.
I, WILLIAM ARTHUR WORRALL, of Clifton Lodge, Queen's Road, Watford,
Process Engraver, 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 connection with feeding gauges for
use with printing machines, and has for its object to provide an arrangement
which will be suitable for cylinder, platten, lithograph and other machines, and
which will feed the paper accurately.
The gauge I propose to employ has a double action giving a movement from
the side towards the centre of the sheet and at the same time a pushing down
action towards the bottom gauge.
According to one arrangement an eccentric movement is employed, the eccentric
completely revolving or only turning through a part of a circle. A triangular
frame is employed one arm of which is provided with a slot and clamp or thumb
screw fitted to this slotted arm fastening the frame to the feeding board. On
the front of the frame a movable support carrying the gauge is fitted this support
working on a screw pivot. The body of the gauge is carried by this support and
underneath this part a knife is placed having a curved rib at its rear side. This
curved rib and the front edge of the knife are placed eccentrically to the pivot,
and the curve may be of any suitable form preferably not circular. The position
of the gauge and consequently the movement of the blade or knife is adjusted
by a long thumb screw passing through bearings in the support so that the gauge
can be moved to any required position with great accuracy, altering the eccentricity
and the movement imparted to the paper.
To operate the device a jointed arm or lever is employed pivoted at one end
to the rear part of the frame. The other end of the jointed arm is connected to
the head of the screw, and to operate the device a rod is employed fitted to the
arm close to the joint, this rod being connected to the finger rod of the machine
or other working part. On moving the rod up the two parts of the arm are drawn
together pulling over the gauge turning it round its pivot and causing the eccentric
to push the paper forward at the same time pressing it down towards the fixed
gauge.
According to a modification instead of employing a pivoted eccentric a sliding
gauge is employed. An adjustable arm or bearing is pivoted to the frame and the
sliding gauge is adapted to slide upon it. The adjustable arm or bearing
is provided with a curved extension concentric with the pivot, this portion being
slotted and furnished with a thumb screw by whch the arm can be secured to the
frame. Owing to the slot the arm can be fixed at any desired angle. The gauge
and knife bear on the side of the arm, and slide upon the edge, the gauge being
connected to the frame by a spring which will withdraw it to its uppermost position
when released. The rod pulls the gauge down this action moving the paper in

page_text: the same manner as the eccentric above described, and the extent of the motion
can be accurately regulated by the position of the arm.
Referring to the accompanying drawings Fig. 1 is a view showing the arrange-
ment for a cylinder printing machine and Fig. 2 is a section of the gauge and
knife, Fig. 3 is a similar view showing the arrangement for a platen machine
and Fig. 4 is a section of the gauge and knife. Fig. 5 is a view showing a modified
arrangement.
In the arrangement illustrated in Fig. 1 a triangular frame A is employed, one
arm of which is provided with a slot a and a thumb screw is used for attaching
to the feeding board. A movable support b is mounted on a screw pivot b¹ upon
the frame A and upon this movable support bis arranged the gauge and the
knife d. This gauge and the edge of the knife are placed eccentrically to the
pivot b. The curve is of any suitable form other than that shown but is prefer-
ably not circular. In order to adjust the position of the knife d upon the movable
support b, a long thumb screw e is passed through a bearing e' upon the support b
and is prevented from moving longitudinally by means of collars and then
passes through a screw-d support 62 attached to the plate 3 to which are attached
the gauge and knife d. It will thus be seen that by turning the screw e the
plate 63 is moved relatively to the movable support b so as to adjust the position
of the gauge c and the knife d thus regulating the eccentricity of the gauge and
knife and the movement imparted to the paper.
In order to operate the device a rod f is pivoted at f¹ to the frame, and is con-
nected at to the rod g which is pivoted at g' to the movable support b. To the
rod f is pivoted at 3 the rod which is connected to any suitable working part
of the machine.
On moving this rod h up, the rod f is moved over operating the rod 9 and pulling
the gauge over on its pivot b¹ and causing the eccentric to push the paper forward,
at the same time pressing it towards the fixed gauges.
In the modification illustrated in Fig. 3 which is more particularly applicable
for platen machines the gauge c is fitted to slide upon the movable portion b and
is adjustable thereon by means of the pinion i operated by means of the double
lever and pivoted upon the movable portion b. This pinion i gears with a
rack attached to the knife c so that as the pinion i is turned the gauge c is inoved
to and fro thus effecting the required adjustment.
In order to operate the knife, the curved lever k pivoted at k¹ is employed. This
is operated from any suitable working part of the machine and at its other end
is pivoted with a slot in which works a pin upon the movable support b so that
as the lever k is vibrated, the gauge c is turned up through a suitable angle, so
as to push the paper forward and also towards the fixed gauges.
In the arrangement illustrated in Fig. 3 instead of the pivoted eccentric a sliding
gauge is employed. This sliding gauge and knife are fitted to slide upon the
adjustable arm m. The rod o is operated from a suitable working part of the machine
to pull the sliding gauge and knife down against the action of the spring n
moving the paper in the same manner as the eccentric above described.
The spring n serves to return the gauge and knife to the upper position. Stops p, pl
are provided to limit the up and down motions.
is pivoted
In order to adjust the position of the gauge and knife the arm m
at n' to the frame A and at the other end is provided with a curve section m³ and
thumb screw m³ for retaining in position when adjusted.
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:
(1) In a feeding gauge for printing machines, the arrangement of mechanism
whereby the paper is pushed forward into correct side register and also towards
the fixed gauges substantially as described.
(2) In a feeding gauge for printing machines the employment of an eccentrically

register and also towards the fixed gauges substantially as described.
(5) In a feeding gauge for printing machines an eccentrically arranged gauge c,
adjusting pinion i, and rack 3, and lever so arranged that when the lever k is
operated from the machine, the gauge c is caused to move eccentrically upon the
pivot band push the paper forward into correct side register and also toward the
fixed gauges substantially as described.

adjusting sector m³, spring n and lever o operated from the machine so that the
gauge and knife are caused to slide upon the arm m and push the paper forward
into correct side register and also towards the fixed gauges substantially as
described.
