IMPROVEMENTS IN PRINTING MACHINES
Year: 1868

page_text: LETTERS PATENT to Philip Henry Hancock, of 107, Tachbrook
Street, Pimlico, in the County of Middlesex, and Joseph Paxton
French, of No. 6, St. Andrew's Terrace, Wandsworth Road, in
the County of Surrey, for the Invention of "IMPROVEMENTS IN
PRINTING MACHINES."
Sealed the 21st August 1868, and dated the 24th February 1868.
PROVISIONAL SPECIFICATION left by the said Philip Henry Hancock
and Joseph Paxton French at the Office of the Commissioners of
Patents, with their 'Petition, on the 24th February 1868.
We, PHILIP HENRY HANCOCK, of No. 107, Tachbrook. Street,.Pimlico,,
in the County of Middlesex, and JOSEPH PAXTON FRENCH, of No... 6,.
St. Andrew's Terrace, Wandsworth Road, in the County of Surrey,.
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN PRINTING MACHINES," to be as follows:-
The improvements relate to means for facilitating the removal of the
sheets after printing thereon in cylinder printing apparatus.
At the time of rotation of the impressing cylinder for the delivery of
the sheet after printing the edge of such sheet is caught or drawn

page_text: between the surface of a small nipping roller and a series of endless
tapes supported between a small roller near the impressing cylinder and
one at a distance therefrom adapted to afford surfaces of tapes for the
receipt of the sheets as delivered. The correct position of these tapes is
preserved by the aid of other guide rollers with which the tapes move
in contact. Each sheet is carried forward by these tapes on to and so
as to be in part supported by a series of arms lying between the tapes
and affixed to an axis of motion. These arms have adjustable stops
applied to them to regulate the position of cach sheet as it passes thereon,
and when a sheet is fully on these arms they move or turn over with
their axis so as to lay the sheets on a table for accumulation or
otherwise. Motion is given to the tapes and to the upper nipping roller
by other tapes which pass partly round the impressing cylinder, one at
each end thereof, thence in necks formed in such nipping roller to
one of the rollers of the bearing tapes so as to give an accelerated surface
motion to that nipping roller and the required motion to these tapes
for a quick delivery of the sheets alternately with the alternate rotation
of the impressing cylinder in opposite directions. The arms on which
the sheet is carried by the tapes are actuated in the traverse motion
of the inking table by a stud therefrom entering the forked end of a
lever which also actuates a segment of teeth taking into another segment
or series of teeth carried by the axis of the arms.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Philip Henry Hancock and Joseph Paxton
French in the Great Seal Patent Office on the 24th August
1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, PHILIP
HENRY HANCOCк, of No. 107, Tachbrook Street, Pimlico, in the County
of Middlesex, and JOSEPH PAXTON FRENCH, of No. 6, St. Andrew's
Terrace, Wandsworth Road, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of February, in the
year of our Lord One thousand, eight hundred and sixty-cight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Philip. Henry Hancock and
Joseph Paxton French, Her special licence that we, the said Philip

page_text: Henry Hancock and Joseph Paxton French, our executors, adminis-
trators, and assigns, or such others as we, the said Philip Henry
Hancock, and Joseph Paxton French, 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 miglit make, use, exercise and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN PRINTING MACHINES,"
upon the condition (amongst others) that we, the said Philip Henry
Hancock and Joseph Paxton French, our executors or administrators,
by an instrument in writing under our or their hands and seals, or
under the hand and seal of one of us or them, 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 Philip Henry Hancock and Joseph
Paxton French, do hereby declare the nature of the said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof,
that is to say:-
The improvements relate to means for facilitating the removal of
the sheets after printing thereon in cylinder printing apparatus.
At the time of rotation of the impressing cylinder for the delivery of
the sheet or sheets after printing, the edge of such sheet or sheets is
caught or drawn between the surface of a small nipping roller and a
series of endless tapes supported between a small roller near the impress-
ing cylinder and one at a distance therefrom adapted to afford surfaces of
tapes for the receipt of the sheets as delivered. The correct position of
these tapes is preserved by the aid of grooves or necks in one of the rollers,
or it may be by other guide rollers with which the tapes move in contact.
Each sheet is carried forward by these tapes on to and so as to be in part
supported by a series of arms lying between the tapes and affixed to au
axis of motion. These arms have adjustable stops applied to them to
regulate the position of each sheet as it passes thereon, and when a sheet
is fully on these arms they move or turn over with their axis so as to
lay the sheets on a table for accumulation or otherwise. Motion is
given-to-the-tapes-and-to-the upper nipping roller by other tapes

page_text: on to the table i, as shewn; the blue lines j represent sheets. Motion
is given to the rollers c and f by means of the tapes k, k, which pass
partly round the impressing cylinder and thence partly round those
rollers c and f; 1, indicates a stud projecting from the traversing
inking table and taking into the fork of the lever m so as to cause
that lever m to move on its fixed axis of motion m', and in so doing
to actuate the arm n by means of the link o, one end of which is
by the stud o connected to the lever m whilst the other end thereof
is by a stud n connected to the outer end of the arm n. The arm n
is affixed to an axis n² to which is applied a segment of teeth 223 which
take into the teeth of a wheel affixed on the axis so as to give
motion to that axis and the desired motion to the arms h, or the
desired motion to the arms h may be obtained by cam or eccentric
applied on the driving or other suitable shaft acting through intermediate
gear.
Having thus described our Invention and means which we adopt in
carrying the same into effect we would have it understood that we do
not confine ourselves to the precise arrangements of parts as shown and
described, as the same may be varied, and in place of the tapes d, d,
cords or elastic bands may be employed also, although we have only
referred to single sheets being delived by the cylinder to be taken
by the tapes d and arms h, two or more of such sheets of the same or
different sizes may be similarly taken side by side at the same time,
but what we do claim is, the adaptation or combination of means acting
in manner and for the purpose substantially as described.
In witness whereof, we, the said Philip Henry Hancock and
Joseph Paxton French have hereunto set our hands and seals,
this Twenty-first day of August, in the year of our Lord One
thousand eight hundred and sixty-eight.
PHILIP HENRY HANCOCK. (L.S.)
