page_text: I, JOHN FREEMAN of 22 Landsdown Terrace, Beeston Hill, Leeds in the County of
York, Engineer do hereby declare the nature of this invention to be as follows:-
My invention has reference to cylindrical type printing machines.
The object is first to provide a means whereby what is known as the "flyer and
taking off cylinder" may be moved away from the main cylinder during the time of
making ready or when large "posters" are being printed which cannot now be done
when such flyer and taking off cylinder are in their operating position on the
machine.
According to my invention I make the arms carrying the flyer and taking off
cylinder in two parts, and attach a chain or other suitable cord to each end of such
armis and to a pulley or disc mounted above the same. When the flyer and taking off
cylinder are required to be moved out of the way I wind the chains or cords onto the
pulleys or drums and thus lift the arms, carrying thereby the flyer and taking off
cylinder clear of the work.
For the purpose of throwing in or out of gear the type cylinder and thus stopping or
starting the same at any given time, I provide on the ordinary incline bar a movable
catch actuated by a hand lever. This lever may be brought into operation for the
проп
purpose of bringing the catch into gear, thus causing the incline to act the
relieving apparatus in connection with the cylinder wheel and thus throwing the type
cylinder out of motion.
Hitherto the operator has to pass underneath the machine to operate the throwing
in or out motion of the double rolling apparatus of the same machine. To obviate

page_text: this inconvenience I employ a hand lever on the arm in connection with the double
rolling apparatus. In connection with this arm is provided a short incline thus by
the action of the lever thereon in one direction, the apparatus is thrown out of gear,
and by moving such lever in the opposite direction the incline is set at liberty and
the apparatus thrown in gear ready for the operation of double inking.
I raise each inking roller separately, or any number of such inking rollers together
by means of inclines on sliding rack or racks actuated by suitable pinions, this being
of great advantage to the operator as he can thus increase or reduce at pleasure the
strength of the colour being printed.

page_text: Improvements in Printing Machines.
I, JOHN FREEMAN of 22 Landsdown Terrace, Beeston Hill, Leeds, in the County of
York, Engineer, 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 cylindrical type printing machines.
The object is first to provide a means whereby what is known as the "flyer and
taking off cylinder," may be moved away from the main cylinder during the time of
making ready," or when large "posters" are being printed, which cannot now be
done when such flyer and taking off cylinder are in their operating position on the
machine, and secondly to a means for throwing in or out of gear the cylinder, and
thus stopping or starting the same at any given time, and thirdly to obviate the
inconvenience of the attendant having to pass under the machine to operate the double
inking or rolling apparatus.
Figs. 1. 2. 3 and 4 are side elevations of various parts shewing my improvements.
A is the framework of the machine, between which is mounted the cylinder B in
ordinary adjustable bearings C. According to my invention I make the arms D
carrying the flyer E and taking off cylinder F separate, or in two parts, and hinged
or carried on studs or shaft G, within the brackets H, and I attach chains J and K or
other suitable cords to the free ends of such arms and to pulleys or discs L, mounted
on a shaft M above the same, in suitable bearings N. When the flyer E and taking
off cylinder F are required to be moved out of the way and clear of the work, I wind
the chains or cords J and K onto the pulleys or drums L by means of the handle O,
the rotary motion being transmitted to the pulleys or drums L through gearing P,
and when the flyer and taking off cylinder are lifted out of the way into position
shewn at Fig. 2, they are retained in such position by the pawl Q and ratchet
wheel R, such ratchet wheel R_being provided on the handle shaft S. When the
flyer E and taking off cylinder F are again required, the pawl Q is relieved from the
ratchet wheel R and the arms D lowered again into position shewn at Fig. 1.
For the purpose of throwing in or out of gear the cylinder B, and thus starting or
stopping the same at any given time, I provide on the ordinary incline bar T, shewn
at Figs. 3 and 4, a moveable catch U actuated by a hand lever V through an arm W
provided with runner X. This lever V may be brought into operation for the purpose
of bringing the catch U into gear with the hinged catch Y attached to the upper part
of the loose slide bar Z, as shewn at Fig. 3, thus causing the incline 1 to act upon
the ordinary relieving apparatus in connection with the cylinder wheel 2, and thus
throwing the cylinder out of motion. The required lift for the incline 1 is transmitted
thereto from the ordinary cam 3, through runner 4, lever 5 and lower bar Z.
Hitherto the attendant has had to pass under the machine to operate the throwing
in or out motion of the double rolling or inking apparatus of the same machine. To

page_text: obviate this inconvenience I employ a hand lever 6 on the arm 7 in connection with
the double rolling or inking apparatus. In connection with this arm 7 is provided a
short incline 8 on the double rolling bar 9, thus by the action of the lever 6 in one
direction the apparatus is thrown out of gear, as shewn at Fig. 4, and by moving
such lever downwards or in the opposite direction, the incline 8 is set at liberty and
the apparatus which is of ordinary construction is thrown in gear for the operation of
double rolling or inking.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The arrangement of apparatus for removing the flyer E and taking off
cylinder F clear of the work, substantially as and for purposes herein set forth.
2nd. The arrangement of apparatus for throwing in or out of gear the cylinder B,
substantially as herein-set forth.
3rd. The arrangement of apparatus for throwing in or out of gear the double
rolling or inking apparatus, substantially as herein set forth.
