Maidstone, Engineer, and Alfred Allnutt, of Loose, near Maidstone,
Paper Manufacturer, both in the County of Kent, for the Invention of
"CERTAIN IMPROVEMENTS IN MACHINERY EMPLOYED IN AND FOR THE MANU-
Sealed the 12th December 1865, and dated the 13th June 1865.
PROVISIONAL SPECIFICATION left by the said William Alonzo Millington
and Alfred Allnutt at the Office of the Commissioners of Patents, with
their Petition, on the 13th June 1865.
We, JONATHAN ALONZO MILLINGTON, of Sandling Road, Maidstone, Engineer,
and ALFRED ALLNUTT, of Loose, near Maidstone, Paper Manufacturer, both
in the County of Kent, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN MACHINERY EMPLOYED IN AND FOR THE MANU-.
FACTURE OF PAPER," to be as follows:-
This Invention relates generally to machines used by paper makers for
cutting sheets of paper of any desired length, and to effect which an adjustable
reciprocating motion is necessary for delivering any required length of sheet
to the action of the cross-cut knife, and has reference more particularly to a
Patent granted to Moses Clark, of Saint Mary's Cray, Engineer, and George
Bertram, of Edinburgh, in the County of Mid Lothian, North Britain, Engineer,
bearing date the 23rd day of July, A.D. 1857, numbered 2021, and also to
improvements we have made upon a paper cutting machine, for which Letters
Patent, bearing date the 10th day of November, A.D. 1849, numbered 12,836,
were granted to Charles Edward Amos, of the Grove, Southwark, in the

page_text: County of Surrey, Engineer, and Moses Clark, of Saint Mary's Cray, in the
County of Kent, upon referring to the Specification and Drawing at Sheet 2
of the last above-mentioned Patent.
With reference to the working of this machine we would remark that unless
the centre of the crank arm shaft, the centre of the crank arm pin, and the
centre of the adjusting pin on the lever marked f, on the Drawing aforesaid,
employed to regulate the length of the sheet, are kept in a correct line with
reference to the excentrics that work the grips and grip rollers when crossing
their centres, it is impossible for the machine to work correctly, and in prac-
tice we have found it essential to the proper working of the machine that the
three centres aforesaid be fixed in a straight line when the aforesaid eccentrics
are crossing their centres. The working of the aforesaid grips or clamps and
grip rolls has hitherto been rendered quite inaccurate whenever the adjusting
pin or the lever f aforesaid has been moved from the point on which it was
first fixed. We propose by this Invention to remedy this defect by introducing
one or more levers either above or below the present reciprocating lever
employed to govern the length of the sheet; and further the connecting rod
which now acts on the adjusting pin aforesaid we propose to dispense with,
and to connect to the additional lever above-mentioned this said lever, to be
supported by a fulcrum suitably placed. Thus by keeping the aforesaid pin
fixed at any given distance from the fulcrum of its respective lever we
ensure a proper and correct motion alike corresponding with the motion of
the grips and clamp aforesaid, and the delivery of the paper. This being
effected we simply impart motion to the present adjusting lever by means of
a connecting rod working either from a moveable or a fixed pin in the afore-
said additional lever in an upward or downward direction, as the case may
be, to the moveable pin in the lever f aforesaid, that now regulates the length
of the sheet. By the above means we are enabled to adjust the length of the
sheet with the present lever without deranging or altering the relative angles
of revolution of the aforesaid excentrics and crank arm.

Patent, bearing date the Thirteenth day of June, in the year of our Lord
One thousand eight hundred and sixty-five, in the eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Jonathan Alonzo Millington and Alfred Allnutt, Her special licence
that we, the said Jonathan Alonzo Millington and Alfred Allnutt, our
executors, administrators, and assigns, or such others as we, the said
Jonathan Alonzo Millington and Alfred Allnutt, our executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "CERTAIN IMPROVEMENTS IN MACHINERY EMPLOYED IN AND FOR
THE MANUFACTURE OF PAPER," upon the condition (amongst others) that we,
the said Jonathan Alonzo Millington and Alfred Allnutt, our executors or
administrators, by an instrument in writing under our, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Jonathan Alonzo Millington and
Alfred Allnutt, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say:-
This Invention relates generally to machines used by paper makers for
cutting sheets of paper of any desired length, and to effect which an adjustable
reciprocating motion is necessary for delivering any required length of sheet
to the action of the cross cut knife, and has reference more particularly to a
Patent granted to Moses Clark, of Saint Mary's Cray, Engineer, and George
Bertram, of Edinburgh, in the County of Mid Lothian, North Britain, Engineer,
bearing date the 23rd day of July, A.D. 1857, numbered 2021, and also to
improvements we have made upon a paper cutting machine for which Letters
Patent bearing date the 10th day of November, A.D. 1849, numbered 12,836,
were granted to Charles Edward Amos, of the Grove, Southwark, in the
County of Surrey, Engineer, and Moses Clark, of Saint Mary's Cray, in the
County of Kent, upon referring to the Specification and Drawing at Sheet 2
of the last above-mentioned Patent.
With reference to the working of this machine we would remark that

page_text: unless the centre of the crank arm shaft, the centre of the crank arm pin, and
the centre of the adjusting pin on the lever (marked f on the Drawing afore-
said), employed to regulate the length of the sheet, are kept in a correct
line with reference to the excentrics that work the grips and grip rollers when
crossing their centres it is impossible for the machine to work correctly, and
in practice we have found it essential to the proper working of the machine,
that the three centres aforesaid be maintained in a straight line when the
aforesaid excentrics are allowing either the grip or grip rollers to act on the
paper, or are disengaging the grips from the paper alternately. The working
of the aforesaid grips or clamps and grip rolls has hitherto been rendered
quite inaccurate whenever the adjusting pin on the lever f aforesaid has been
moved from the point on which it was first fixed. We propose by this Inven-
tion to remedy this defect by introducing one or more levers either above or
below the present reciprocating lever employed to govern the length of the
sheet. And further the connecting rod which now acts on the adjusting pin
aforesaid we propose to connect to the additional lever above mentioned, this
said lever to be supported by a fulcrum suitably placed; thus by keeping the
aforesaid pin fixed at any given distance from the fulcrum of its respective
lever, we ensure a proper and correct motion alike corresponding with the
motion of the grips and clamp aforesaid and the delivery of the paper.
This being effected we simply impart motion to the present adjusting lever by
means of a connecting rod working from a fixed pin in the aforesaid additional
lever in an upward or downward direction, as the case may be, to the movable
pin in the lever f aforesaid that now regulates the length of the sheet.
By the above means we are enabled to adjust the length of the sheet with
the present lever without deranging or altering the relative angles of revolution
of the aforesaid excentrics and crank arm; and in order to explain our said
Invention as completely as possible, we now proceed to describe the best
means we are acquainted with for carrying the same into practical effect,
reference being had to the illustrative Drawing accompanying these Presents,
and to the numeral figures and letters of reference marked thereon respec-
tivaly as follows •

page_text: ing the length of the sheet to be cut; I a vibrating lever connected at one
end by a rod at K to the nut 6 of the lever G, and at the other end by a long
rod at L to the crank at C; M vibrating lever for working the cutting knife E.
The other parts of the machine are arranged and actuated as described in and.
by the Specification and Drawings of the Patent of the 10th November,
A.D. 1849, No. 12,836, above referred to. We would here remark that if
desirable the pin in the crank arm at C may be made adjustable, and the pin
in the nut 6 be made stationary. The operations of the above improvements
are as follows:-Having adjusted the nut and pin 6 in accordance with the
length of the sheets of paper to be cut, upon motion being imparted to the
crank arm at C such motion will be transmitted by the rods and lever
I, K, L, to the drum lever G, which said lever will advance the drum and
paper thereon the required distance, the grip will then hold the paper whilst
it is being cut by the knife E. By these improvements the position of the
nut may be altered to cut sheets of different lengths without having to alter
and adjust the other parts of the machine as was heretofore required, by
which considerable saving of time will be effected.
l
Having now fully described and set forth the nature and object of our
said Invention for "Certain Improvements in Machinery employed in and for
the Manufacture of Paper," together with the best means we are acquainted
with for carrying the same into practical effect, we would remark in con-
clusion that we do not intend to limit or confine ourselves to the precise
mechanical arrangements above described and represented, as the same may
be varied so as to produce a similar effect; and we hereby declare our Inven-
tion to consist in and we claim as follows:-We claim the altering of the
adjusting pin of paper cutting machines (as for example the pin at 6) without
deranging or altering the other working parts of paper cutting machines so as
to be able to cut sheets of paper of different lengths as above stated.
In witness whereof, we, the said Jonathan Alonzo Millington and
Alfred Allnutt, have hereunto set our hands and seals, this Eighth day
of December, in the year of our Lord One thousand eight hundred
and sixty-five.
