A New or Improved Method of and Means for Feeding Sheets of
Paper to Printing Machines, Specially Designed for Use in
Connection with Double Revolution Perfecting Machines
1, FREDERICK PAYNE, of the firm of Payne and Sons, of Atlas Works, Otley
Yorkshire, Machine Makers, do hereby declare the nature of this invention to be as
follows:-
:-
My invention has reference to a new or improved method of and means for feeding
sheets of paper to two-revolution perfecting machines, or to one-revolution perfecting
or other descriptions of printing machines where applicable, the object of such
invention being to enable the machine to be driven at a higher rate of speed, to secure
a more accurate feed, and to reduce to a minimum the liability of damage being done
to the sheets of paper in the transfer thereof from the feeding board to the impression
cylinder by the "grippers" employed for that purpose.
In order to carry out my invention when used in connection with a two revolution
perfecting machine, I make use of the ordinary inclined feed board or table which is
provided with ordinary "smoothers" for holding, steadying, or guiding the sheets of
paper as they are drawn from the said table. Mounted on a rod or bar extending
across the machine and placed immediately under the end of the table are a number
of gauges whose ends project a little above the surface of the table and against which
the attendant places one edge of the sheet of paper to be fed to the machine. Above
the first impression or inner forme cylinder place a rocking shaft supported in
suitable bearings at each side of the machine, upon which are mounted two or more
arnis extending to near the upper surface of the first impression cylinder, the
extremities of the said arms carrying or having cast thereto a square or other suitable
form of rod or bar having a number of india rubber rings or rings composed of any
other suitable material, placed at short distances apart thereon, or instead of employing
rings the said bar may be covered or coated with india rubber or other suitable
material. The extremities of the said arms also support a second rod or bar upon
which is mounted a number of "grippers." Motion is given to the rocking shaft by
means of rods or levers operated by cam or tappet driven by or from any suitable

rotary part of the machine, and consequently gives a reciprocatory curvilinear motion
to the arms mounted the reon. Spiral springs are also employed to steady the working
of the parts. Friction bowls are connected by short arms to the rod carrying the
grippers," so that as the arms and parts connected therewith move forward towards
the feed board, the said bowls come against and ride upon inclined or cam surfaces
formed on the ends of levers pivotted to the framework, which cause the "grippers"
to open and pass under the sheet of paper on the feed board, and at the same time the
table is caused to rise a little by means of rods operated by cams tappets, or other
suitable means, so that the paper is raised clear of the gauges and the arms having
reached the extent of their movement in the forward direction, the action of the bowls
upon the cams or inclined surfaces causes the "grippers" to close against the india
rubber rings and hold the edge of the paper securely between the said "grippers"
and rings. The arms now commence their return movement, the parts being so
arranged and timed with respect to the velocity of the first impression cylinder and
the position of the "grippers" thereon that when the said " grippers open at a
position at the top of the cylinder, the edge of the sheet of paper held by the
grippers on the rod supported on the oscillating arms is brought under the
grippers" in the cylinder, which then close and carry the paper forward, but
the grippers" carried by the oscillatory arms do not immediately release their hold
upon the paper when the grippers" on the cylinder close, but retain their hold for a
short distance, when the friction bowls previously mentioned come against and ride
upon inclined or cam surfaces, thereby causing the "grippers" connected with the
said arms-to open and release their hold upon the paper, which is now taken round by
the K
grippers on the cylinder, and after receiving the first impression is taken
partially round again and delivered to the second impression or outer forme cylinder
in the ordinary way. By the means above set forth, 1 am enabled to dispense with
the turnover or half circular movement of the "grippers" on the cylinder and to take
the paper from the feeding apparatus by causing the said grippers to simply turn a
part of a revolution on their axis, whereby "back lash or vibration thereof, which
has hitherto been caused by the momentum given to the said "grippers" by the
turnover movement and the velocity of the cylinder, and the consequent failure of the
grippers to hold the paper is obviated, whilst the method of taking the paper from
the feed board and delivering it to the first impression cylinder allows the machine to
be driven at an increased rate of speed, without tearing or otherwise damaging the
sheets of paper, as is the case under the present system of feeding.

Although I have described my improved feeding apparatus in connection with a
two revolution perfecting machine it will be understood that the same apparatus can
be used for feeding sheets of paper to one revolution perfecting machines or to other
descriptions of printing machines where applicable.

Paper to Printing Machines, Specially Designed for Use in
Connection with Double Revolution Perfecting Machines.
I, FREDERICK PAYNE, of the firm of Payne and Sons, of Atlas Works, Otley,
Yorkshire, Machine Makers, 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 has reference to a new or improved method of and means for feeding
sheets of paper to two revolution perfecting machines, or to one revolution or other
descriptions of printing machines where applicable; the object of such invention
being to enable the machine to be driven at a higher rate of speed, to secure a more
accurate feed, and to reduce to a minimum the liability of damage being done to the
sheets of paper in the transfer thereof from the feeding board to the impression
cylinder by the grippers employed for that purpose.
In order that my invention may be better understood, I will now make reference to
the accompanying sheets of Drawings, wherein Fig. 1 is elevation of such parts of a
two revolution perfecting machine as are necessary to shew the application thereto of
my invention.
a is the framing of the machine, the first impression or inner forme
cylinder is the second impression cylinder, and d the usual inclined feed board or
table arranged in the ordinary manner. e are gauges, of which there may be any
number, arranged at the bottom end of the inclined feed board. These gauges are
attached to a rod suitably mounted, extending across the machine, the said gauges
being made with a projection or ridge g for the lower edge of the sheet of paper to
rest against. On the rocking shaft are fastened, by set screws or other means two
or more vertical arms i, sufficiently long to extend near the upper surface of the first.
impression cylinder. At the furthest "extremity of the armis I fix a bar or rod j
having thereon a number of rings composed of indiarubber or other suitable
substance. At the extremities of the said arms i is another rod or bar upon which
is mounted a number of ordinary grippers m (see Fig. 3) so that when oscillatory
motion is given to the rocking shaft through the intervention of connecting rods
and cams
the vertical arms and grippers m are caused to oscillate, or have a
pendulous motion, to and from the inclined feeding board d, as shewn in Fig. 2, for
the purpose of receiving the paper and carrying it to the first impression cylinder b.
Fig. 4, (sheet 2) is an enlarged view of the improved parts.
I will now explain how my improved apparatus operates, and how paper to be
printed upon is removed from the feeding board d onto the first impression cylinder.
Immediately after the edge of a sheet of paper is resting against the ridge of the
gauge e, the feed table d is caused to rise a little distance by means of vertical rod p
and bell crank lever, operated by revolving cams, by which means the edge of the
paper is raised clear of the gauges, by which time the arms i will have reached the
extent of their forward movement as shewn in Fig. 2, so as to allow the grippers
thereon to seize the paper. During the time the arms are advancing towards the
feed board the bowl will be riding upon the cam or inclined surface formed on the
front end of the bell crank lever or finger u, the effect of which is to open

page_text: the gripper m ready to receive the paper, and when the rod p rises to lift the feed
board, the camined surface of the bell crank lever u is lowered whereby the pressure
is removed off the bowl to allow the grippers to close and seize the paper and hold or
nip the edge of the said paper against the indiarubber or other yielding surface on
the bar, the oscillating arms i-then commence their return movement, the parts
being so arranged and timed with respect to the velocity of the first impression
cylinder and the position of the grippers to thereon, that when the grippers which
lave hold of the paper are made to open by the bowl a working underneath the
hent end of the bell crank lever 3, causing the grippers to release their hold of the
paper, but only to be taken hold of by the grippers we connected to the first impression
cylinder whereby the paper is taken around and passed over the forme, and afterwards
taken to the second impression cylinder c in the ordinary manner. The free end of
the bell crank lever y is placed into position to be acted upon by the bowl x at a
given time by the movement of the connecting rods when the grippers require to
he opened for releasing their hold upon the paper. It must be understood that whilst
the cam surfaces u and y are employed to open the grippers at a given time, they are
closed in the ordinary manner by a spiral spring passing around the little axles which
carry the grippers.
By the means above set forth I am enabled to dispense with the turnover or half
circular movement of the grippers on the cylinder and to take the paper from the
feeding apparatus by causing the said grippers to simply turn a part of a revolution
on the axis, whereby the "back lash" or vibration which has hitherto been caused by
the momentum given to the said grippers by the turn over movement and the velocity
of the cylinder, and the consequent failure of the grippers to hold the paper is now
obviated, whilst the method of taking the paper from the feed board and delivering it
to the first impression cylinder allows the machine to be driven at an increased rate
of speed without tearing or otherwise damaging the paper in taking it from the
machine, as is now the case.
Although I have described my improved feeding apparatus in connection with a
two revolution perfecting machine, it will be understood that the same form of
apparatus can be used for feeding paper to one revolution perfecting machines, or
to other descriptions of printing machines where applicable.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is
Firstly. The employment of one or more grippers in combination with the bar j
attached to a pendulous lever arm for receiving paper from a feeding board and
transferring such paper to a printing cylinder all arranged and operated substantially
as shewn and described.
Secondly. In combination with a pendulous leyer arm carrying grippers and
horizontal bar 1, the employment of friction bowls which are operated by cam
surfaces for opening the grippers in manner substantially as herein shewn and
described.
Thirdly. The use of hinged gauges in combination with a paper feeding board for
supporting the edges of the sheets of paper.
Fourthly. The means substantially as heroin shewn and described for raising the
feed board for the purpose of placing the edges of the paper above a supporting gauge
arranged as shewn and described.
