PROVISIONAL SPECIFICATION.
Improvements in or relating to Printing Machines.
We, Jons ELLIOTT and ROBERT ELLIOTT of Steel Croft Foundry, Otley, in
the County of York, Printers Engineers, do hereby declare the nature of this
invention to be as follows:-
።
This invention relates to improvements connected with the sheet delivery
apparatus of letter press cylinder machines especially those of the kind known as
the Wharfedales," whereby the apparatus and its adjuncts above the cylinder
may be caused to occupy less space than heretofore, and offer less obstruction to
the operator or printer, the manipulation also being rendered easier.
When printing fine book and cut work upon cylinder machines the printer is
often occupied for days together in making ready on the forme bed and also in
patching pieces of paper on to the surface of the cylinder to make up for any
defects there may be in the block or type to be printed from; it is therefore
desirable that the forme bed and cylinder should be clear all round to allow of the
work being done as speedily and readily as possible.
In carrying our invention into effect we prefer to connect the delivery apparatus
with the cylinder stand or main frame of the machine by at least two jointed levers
on each side adapted to operate as a parallel motion, a horizontal shaft preferably
connecting one of the levers on each side.
Various devices may be employed for operating this mechanism but a convenient
one is constructed as follows
1
A swivel nut is secured in a suitable place upon one of the two shaft connected
levers and a long screw passes through this and carries at one end a bevil or mitre
wheel adapted to engage with a corresponding wheel upon a horizontal shaft
operated by a hand wheel; or the second bevil wheel may be formed upon the
hand wheel itself. The screw may be supported in a swivel bearing and the action
is as follows
11
Upon turning the hand wheel the screw through the intervention of the bevil
wheels is caused to revolve turning the mut and causing the lever to which the
nut appertains to turn upon its centre of motion. This has the effect of operating
the whole parallel motion and raising the delivery apparatus away from the
cylinder to the full length of the levers, the screw adapting itself to the change of
position due to the radial path of its nut.

COMPLETE SPECIFICATION.
Improvements in or relating to Printing Machines.
We, JOHN ELLIOTT and ROBERT ELLIOTT of Steel Croft Foundry Otley, in
the County of York, Printers Engineers, 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 :-
This invention relates to improvements connected with the sheet delivery
apparatus of letter press cylinder machines especially those of the kind known as
the Wharfedales," whereby the apparatus and its adjuncts above the cylinder

page_text: may be caused to occupy less space than heretofore, and offer less obstruction to
the operator or printer, the manipulation also being rendered easier.
When printing fine book and cut work upon cylinder machines the printer is
often occupied for days together in making ready on the forme bed and also in
patching pieces of paper on to the surface of the cylinder to make up for any
defects there may be in the block or type to be printed from; it is therefore
desirable that the forme bed and cylinder should be clear all round to allow of the
work being done as speedily and readily as possible.
Our invention will be best understood by reference to the accompanying drawing
which is a side elevation of the necessary parts of the machine constructed to carry
it into effect. The machine generally is an ordinary Wharfedale " cylinder
printing machine and the drawing shows what is necessary to the elucidation of
our present invention.
A represents a portion of the framing, B the printing cylinder and C the framing
of the delivery apparatus which is placed above the printing cylinder. Upon each
side of the delivery frame C are pivotted two links D and E. The levers D are.
merely pivotted on each side at D' to the frame C and at D2 to the main frame A.;
the levers E are merely pivotted at each side at E¹ to the frame C, but at their
other ends are keyed or otherwise secured to a shaft E which traverses the
machine and has bearings in the frame A. and carries one link E at each end.
The link E carries a swivel nut F through which passes the screw G provided
with a head at its upper end to prevent the nut working off. At its lower end
the screw G is carried in a sleeve bearing, not shown in the drawing, and adapted
to turn about the centre H of the hand wheel 1. This centre may either be a shaft
or the boss of the wheel. Upon its lower end the shaft G carries the mitre or bevel
wheel which engages with the corresponding wheel K concentric with the hand
wheel and which may be formed upon the boss thereof or separately secured upon
the shaft H if such be employed. The sleeve keeps the wheels J and K in gear in
their proper relative positious and allows the wheel J and screw G to move as
required radially about the centre, H. The thread of the screw G may be either a
right or left hand, in the drawing the latter is shown, as that with the arrangement
shown would allow of the hand wheel I being turned by the operator in the
direction most convenient to him.
The operation is as follows:-The combination of the frame C and links E form
a parallel motion by which the delivery apparatus can be raised from its normal
position as indicated by the dotted lines in the drawing this movement is effected
in the following manner. By turning the hand wheel I the bevel wheel K is
revolved and gearing with revolves the screw G this causes the nut F to ascend
and carries the link E with it. The link E being fixed to the shaft E² raises
similarly the link E at the other side of the machine and in so doing lifts the
delivery apparatus with which the links are connected; the links D at cach side of
the machine are operated by the frame C and merely turn upon their centres so as
to keep the delivery apparatus in its proper position as it rises. The dotted lines
in the drawing indicate the elevated position of the delivery apparatus and also the
ultimate position of the screw G showing the nut F raised to the full limit permitted
by the head G of the screw G. The delivery apparatus is returned to its normal
position by reversing the direction of movement given to the hand wheel I. When
at its highest limit the delivery apparatus is out of the way of the printer who can
then conveniently get at the printing cylinder.
It will be observed that modifications can be made without departing from the
spirit of this invention, for example, we have previously described the turning of
the screw Gas being effected by the hand wheel I but it will be understood that so
long as the requisite rotary movement is imparted to the screw G it is immaterial
whether a hand wheel or other means be employed for the purpose. Also instead
of the nut F being connected with the link E it might be connected with an
independent arm secured to the shaft centrally or otherwise.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
1. In a cylinder printing machine the combination with the delivery apparatus
of a parallel motion substantially as and for the purpose described and illustrated
in the accompanying drawing.
2. The combination with a cylinder printing machine of a delivery apparatus
whose only connection with the machine is a series of links substantially as
described and illustrated in the accompanying drawing.
3. The combination with a printing machine and its delivery apparatus of links
such as D and E, nut F screw and bevel wheels J and K substantially as and
for the purpose described and illustrated in the accompanying drawing.
4. The combination and arrangement of parts constituting the complete printing
machine delivery apparatus substantially as described and illustrated in the
accompanying drawing.
