Sealed the 27th June 1879, and dated the 31st December 1878.
PROVISIONAL SPECIFICATION left by the said David Payne and Frederick
Payne at the Office of the Commissioners of Patents on the 31st December
1878.

"IMPROVEMENTS IN PRINTING MACHINERY."
This Invention relates to printing machinery in which the oscillatory motion of
the cylinder is derived from the type table or bed, and our improvements are
equally applicable to machinery constructed on this principle, having either one or
two cylinders.
Our improvements consist in constructing such machines so as to accomodate the
stroke or movements of the type bed to the length of surface required to be printed,
and this we effect by means of an ordinary moveable crank, which communicates
motion to the type table so as to move the same the distance necessary for giving
the impression, and releasing the printed sheet previous to the commencement of
the return movement of the table. As it is necessary to bring the grippers opposite
the feed board whatever the size of the sheet may be, we effect this by mounting
the cylinder and wheels upon the shaft in such manner that they may be moved
independently of each other, and so that the grippers, which are fixed to one part
of the surface of the cylinder may by turning the cylinder be brought opposite the
feed board, and when properly adjusted, the wheels and cylinder are secured firmly
together by bolts and nuts passing through slotted grooves provided for the purpose.
By these improvements we are enabled to utilise the whole of the surface of the
cylinder for printing upon, and to dispense with all provision for moving the grippers
upon the cylinder, where such has hitherto been necessary.

"IMPROVEMENTS IN PRINTING MACHINERY."
This Invention relates to printing machinery in which the oscillatory motion of
the cylinder is derived from the type table or bed, and our improvements are equally.
applicable to machinery constructed on this principle, having either one or two
cylinders.
Our improvements consist in constructing such machines so as to accomodate the
stroke or movement of the type bed to the length of surface required to be printed,
and this we effect by means of an ordinary moveable crank, which communicates
motion to the type table, so as to move the same the distance necessary for giving
the impression, and releasing the printed sheet previous to the commencement of
the return movement of the table.
As it is necessary to bring the grippers opposite the feed board whatever the size
of the sheet may be, we effect this by mounting the cylinder and wheels upon the
shaft in such manner that they may be moved independantly of each other, and so
that the grippers, which are fixed to one part of the cylinder may, by turning the
cylinder, be brought opposite the feed board, and when properly adjusted, the wheels
and cylinders are secured firmly together by bolts and nuts passing through slotted
grooves provided for the purpose.
By these improvements we are enabled to utilize the whole of the surface of the
cylinder for printing upon, and to dispense with all provision for moving the grippers
upon the cylinder where such has hitherto been necessary.
In order that our Invention may be more fully understood, we have hereto
annexed two Sheets of Drawings illustrative thereof.
Fig. 1 is side elevation of a machine constructed and arranged according to our
Invention, and Fig. 4 is plan view of same; A is the travelling wheel, which is
connected by moveable crank B and connecting rod C to the driving wheel D. The
travelling wheel runs on the rack rail E, and gives reciprocating motion to the type
table F in the usual manner. G, G¹, are the cylinders provided with grippers H
for holding the sheet when the same is fed to them from the feed boards J. These
cylinders are caused to rotate by the wheels K on their axes gearing with the rack
L on the type table. In practise it is desirable that the rotation should not be
continued beyond the time actually required to produce the impression, which will
of course depend upon the length of sheet to be printed, and in a single cylinder
machine this can be regulated by means of a moveable crank alone, but in a double
cylinder machine every alteration in the length of sheet necessitates the grippers
being placed in different positions upon the cylinders, in order that as soon as one
cylinder has completed its impression, and the return movement is about to com-
mence, the second cylinder and grippers shall be in the proper position with regard
to the feed board to receive a sheet.
In order to effect these changes in the relative position of the grippers, we mount
either the wheels K or the cylinders loose upon their shafts in such manner that
they may be moved independantly of each other, so that the grippers, which are
fixed to one part of the cylinder may, by turning the cylinder, be brought opposite
the feed board, and when properly adjusted, the wheels and cylinders are secured
firmly together by bolts and nuts, as shewn in Figs. 2 and three, the latter view being
a section of cylinder and wheel. The end of the cylinder is slotted at N for the
reception of a bolt M, which passes through the wheel K, and the cylinder and
wheel are then secured firmly together by the nut P, which screws on the bolt.
Having now described the nature and particulars of our Invention, and shewn
the manner in which the same is to be or may be performed or put into practice,

page_text: we would have it understood that we claim as our Invention the construction and
combined arrangement of the wheel K and cylinder G, for the purpose substantially
as herein shewn and described.
In witness whereof, we, the said David Payne and Frederick Payne, have
hereunto set our hands and seals, this Twenty-sixth day of June, in the year
of our Lord One thousand eight hundred and seventy-nine.
