IMPROVED "TAKING OFF' APPARATUS FOR PRINTING MACHINES.
Year: 1879

page_text: LETTERS PATENT to John Esson, of Johnson's Court, Fleet Street, in the City'
of London; Printers' Engineer, for the Invention of "IMPROVED "TAKING OFF'
APPARATUS FOR PRINTING MACHINES.".
Sealed the 12th September 1879, and dated the 14th March 1870.
PROVISIONAL SPECIFICATION left by the said John Esson at the Office of
the Commissioners of Patents on the 14th March 1879.
JOHN ESSON, of Johnson's Court, Fleet Street, in the City of London, Printers'
Engineer. "IMPROVED TAKING OFF' APPARATUS FOR PRINTING MACHINES,"
This Invention relates to a special arrangement of apparatus for "taking off"
the sheets of paper from cylinder printing machines, whereby each sheet in suc-
cession is received from the cylinder between tapes and pushed on to a board
without hand labour, the tapes moving intermittently and the driving rollers
continuously.
According to my Invention I fix a bracket on each of the main cylinder bearings
by screws to carry a double set of parallel faced rollers over which tapes psss; one
of the rollers of each set is driven one by a gut band from the main shaft to move
its set of tapes, the other by a distinct gut band on the first of the second set from
a whorl on the first roller of the first set. The first named roller works the lower
tapes and is kept continually running while the main shaft rotates, as is also
the first roller of the second set, the two first rollers of each set being free by a
slackness given to the tapes while the type table moves in one direction, the other
rollers and the tapes standing still the while. On the type table moving in the
reverse direction the tapes become tightened and the printed sheet as it leaves the
cylinder is taken hold of by the "taking off" tapes and delivered.
The speed of the rollers is in proportion to that of the cylinder, that the tapeš
carry the paper away without a drag or the liability of tearing the sheet.

page_text: One roller of the pair nearest the delivery end of the apparatus is adjustable
around the other to determine the angle at which the sheet shall be delivered.
The above describes the apparatus when fixed to a stop motion machine with
upper delivery, but it is applicable to all single and double cylinder machines in
which a type table is used.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Esson in the Great Seal Patent Office on the 13th September
1879.
JOHN ESSON, of Johnson's Court, Fleet Street, in the City of London, Printers'
Engineer. "IMPROVED TAKING OFF' APPARATUS FOR PRINTING MACHINES."
This Invention relates to special arrangement of apparatus for "taking off"
the sheets of paper as printed from cylinder printing machines, whereby each sheet
in succession is received from the cylinder between tapes and pushed on to a board
without hand labour, the tapes moving intermittently and the driving rollers
continuously.
According to my Invention I fix a bracket A, which is represented in the annexed
Drawings, Figure 1, on each of the main cylinder bearings B of a stop motion
machine, or to the tape brackets of a perfecting machine by screws to carry a double
set of parallel faced rollers C, C, D, D¹, over which tapes E, E, F, F, pass; one of
the rollers of each set is driven, one, C, by a gut band Ġ from the main shaft H to
move its set of tapes F, F, the other roller D, by a distinct gut band I on the first
of the second set from a whorl on the first roller of the first set. The first named
roller C works the lower tapes F, F, and it is kept continually running while the
main shaft H rotates, as is also the first roller D of the second set, the two first
rollers of each set being free by a slackness given to the tapes by the opening in
the cylinder being nearest the table while the type table moves in one direction and
the cylinder K is stationary, the other rollers C¹, D', J, and the tapes E, F, standing
still the while.
On the type table moving in the reverse direction for the type to be reinked, the
tapes E, F, become tightened and the printed sheet as it leaves the cylinder in the
direction shown by the arrow on Figure 1, is taken hold of by the "taking off"
tapes, and delivered by the tapes on to the board L automatically in a superposed
manner, as shown; side guides M, M, being fitted on the board to ensure a level
piling of the sheets.
The speed of the rollers is in proportion to that of the cylinder that the tapes
carry the paper away without drag or the liability of tearing the sheet.
One roller of the pair nearest the delivery end of the apparatus may be adjust-
able, to determine the angle at which the sheet shall be delivered. The above
describes the apparatus when fixed to a stop motion machine with upper delivery,

page_text: as in Figure 2, but it is applicable to all single and double cylinder machines in
which a type table is used.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim,-
The combination of parts forming a taking off apparatus, to be attached by its
brackets to the main cylinder bearings of a stop motion printing machine or to
the tape brackets of a perfecting machine, as described, and whether to the stop
motion cylinder printing machine, shown in Figure 2 of the Drawings, or to any
other printing machine in which a type table is used, as set forth.
In witness whereof, I, the said John Esson, have hereunto set my hand and
seal, this Thirteenth day of September, in the year of our Lord One thousand
eight hundred and seventy nine.
