and Lithographic Printing Machinery.
ALEXANDER HERVEY SEGGIE Broughton Market Edinburgh Scotland Engineer
do hereby declare the nature of my invention for IMPROVEMENTS IN SELF DELIVERY
APPARATUSES FOR LETTERPRESS AND LITHOGRAPHIC PRINTING MACHINERY to be
as follows:-
The Self Delivery or Flyer cylinder of the machine is made to roiate in bushes
guided in slots in brackets bolted to the side frames and which also carry the
Impression Cylinder. A horizontal shaft is carried on hearings at top of brackets; on
it are fixed two balanced cranks or dises with pins connected with Flyer cylinder by
means of links. A worm wheel keyed on horizontal shaft is worked by a worm keyed
on another shaft carried in bearings on brackets and terminating with a hand wheel
at any convenient position within reach of the attendant. The centre of the horizontal
shaft is placed relative to the centre of slot so that the link is as nearly as possible in
line with it during the lifting and lowering of the cylinder.

I, ALEXANDER HERVEY SEGGIE Broughton Market, Edinburgh, Scotland, 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:
The Self delivery or Flyer Cylinder of the machine, is made to rotate in bushes,
guided in slots in brackets, holted to the side frames. A horizontal shaft is carried in
bearings, at top of these brackets and on it are fixed two balanced cranks or dises
with pins connected with the Flyer cylinder bushes by means of links. A worm
wheel keyed on horizontal shaft is worked by a worm keyed on another shaft carried
in bearings on the brackets and terminating with a hand wheel at any convenient
position within easy reach of the attendant. The centres of the horizontal shaft are
placed relative to the centres of the slots so that the link is as nearly as possible in
line with them during the lifting and lowering of the cylinder.
The following description explains the nature of the invention with reference to the
accompanying drawings.
Fig. 1. is an end elevation and Fig. 2 is a longitudinal elevation. A is the
Impression cylinder. B is the Flyer cylinder rotating in bushes guided in slots in
brackets GG. The horizontal shaft is carried in the bearings at the tops
of the brackets, on it are keyed two balanced cranks or discs D) D with pins
connected with the bushes of Flyer cylinder by means of the links H H.
A worm wheel E keyed on horizontal shaft is worked by a worn F keyed on another
shaft I. At the end of shaft I is keyed a hand wheel K within easy reach of the
attendant. The centres of the horizontal shaft C are placed relative to the centres of
the slots in brackets G G so that the links H H are as nearly as possible in a line
with the centres of slots during the lifting or lowering of the Flyer cylinder B. By
turning the worm shaft IF in the one or the other direction the Flyer cylinder can
be raised or lowered as may be. By this arrangement of lifting gear a more than
ordinarily simple and speedy means of raising and lowering the Flyer cylinders of
Printing Machines is obtained and as the lifting gear is self sustaining the Flyer
cylinder will remain suspended in any position between the two centres of the lift
without the introduction of stops or catches.
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,
The use and employment of a Lifting Gear operated in the manner and for the
purpose drawn and described.
ALEXANDER HERVEY SEGGIE.
