PROVISIONAL SPECIFICATION.
Improvements in the Delivery Apparatus of Printing Machines.
I, THOMAS GALLOWAY DAWSON, of the firm of William Dawson & Sons, of
Ashfield Foundry, Otley, in the County of York, Printer's Engineer, do hereby
declare the nature of this invention to be as follows:-
:-
This invention relates to an improved method of mounting the sheet delivery
apparatus on "Wharfedale," and similar kinds of letterpress printing machines,
whereby the apparatus and its adjuncts above the cylinder occupy less space, are not
so much of an obstruction to the operator or printer, also easier and more economical
to work than hitherto.
When printing fine books, and cut work on cylinder machines, the operator, or
printer, is occupied sometimes for days together in making ready, or patching pieces
of paper on the surface of the cylinder to make up for any defects or irregularities
there may be in the blocks or type to be printed from hence it necessary that the
surface of the cylinder should be clearly accessible all round to allow of this work
being done as rapidly as possible.
:
In carrying out my improvement, 1 mount the delivery apparatus on two sliding
bars placed in an upright position, one at each side by preference within the frame of
the machine.
These bars are supported on levers fixed horizontally on a shaft placed across the
machine, and on this shaft opposite to the levers is placed a weight to counterpoise
the weight of the upright bars and delivery apparatus fixed on the ends of the said
bars.
The apparatus may be moved up to the required height, or down by a handle, which
may be placed on the cross shaft or other convenient position. When moved to the
highest point, the apparatus is entirely out of the way of the operator, or printer,
and the sheets when in this position can be taken off by hand if

COMPLETE SPECIFICATION..
Improvements in the Delivery Apparatus of Printing Machines.
I, THOMAS GALLOWAY DAWSON, of the firm of William Dawson and Sons, of
Ashfield Foundry, Otley, in the County of York, Printers' 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:
This invention relates to an improved method of mounting the sheet delivery
apparatus on "Wharfedale" and similar kinds of letterpress printing machines,
whereby the apparatus and its adjuncts above the cylinder occupy less space and are
not so much of an obstruction to the operator or printer; also easier to work and
more economical in construction than hitherto.
When printing fine books and cut work on cylinder machines, the operator or
printer is occupied sometimes for days together in making ready or patching pieces
of paper on the surface of the cylinder to make up for any defects or irregularities
there may be in the blocks or type to be printed from hence it is necessary that the
surface of the cylinder should be clearly accessible all round to allow of this work
being done as rapidly as possible.

page_text: In the accompanying sheet of drawings,
"Wharfedale" printing
Fig. 1. represents a side elevation of such portions of a
machine as are required to explain my invention which is added thereto;
Fig. 2. is a plan or a portion of the delivery apparatus.
Fig. 3. an enlarged end view of one of the arms of the delivery apparatus, the
reciprocating sleeve therein is in section, and
Fig. 4. an enlarged sectional detail of the end of the operating arm for giving
motion to the sleeve and flyer.
The cylinder A. shafts B. flyer C. and carrying tapes D. of the delivery apparatus
are of the ordinary construction, receive motion from the impression cylinder E. to
which no claim is made, and are carried by side plates F. attached to two upright
sliding bars G. within the frame H. of the machine.
The upright sliding bars G. are cach provided with a link J. for connecting same
to the respective levers K. secured to horizontal shaft L. extending across the
machine, and on the said shaft projecting in the opposite direction is one or more
weighted levers M. for balancing the weight of the upright sliding bars G. and
delivery apparatus fixed at the top of the same.
The sliding bars G. are kept in an upright position by passing through suitable
guides N. and may be moved up or down by a handle P. attached to one of the sliding
bars G.
When moved to the highest position, the delivery apparatus as shown by dotted
lines is entirely out of the way of the operator or printer, thereby giving free access
to the surface of the impression cylinder E. for enabling the operator or printer to
correct any defects or irregularities there may be in the blocks or type to be printed
from, so that a correct and even impression may be obtained.
In order to operate the flyer C. for removing the sheets from the carrying tapes D.
one of the side frames of the delivery apparatus is extended at Q. on which is
placed a sleeve R. having a toothed rack S. secured in the bottom portion
of its interior and with which gears a pinion T. secured on the end of the flyer
shaft.
On the ordinary shaft U. is secured a cam V. which on rotating, operates the
lever V on its fulcrum pin, so that when the top end is connected with the sleeve R.
the latter reciprocates on the curved portion Q. of side frame, the toothed rack S.
causing the pinion T. and flyer shaft to revolve a portion of a revolution, and the
flyer C. to move the usual distance for removing the sheets from the carrying tapes D.
to a delivery board placed in any convenient position.
The connection between the reciprocating lever V and the sleeve R. is
accomplished in the following manner-In the top end of the said lever a hole is
bored for the reception of a stud W. and spiral spring, which is compressed between
a shoulder formed on the stud and the bottom of the said hole, the stud being
retained therein by means of a small screw at Y. and when operating the sleeve, the
end of stud engages with a hole bored in the underside of sleeve by which it is caused
to reciprocate.
On lowering the distributing apparatus to the position shown by full lines for
removing the sheets, on the sleeve R. coming in contact with the end of stud W.
"the spiral spring allows it to yield until the end of stud is opposite a hole bored in
the underside of the sleeve, when the compressed spring forces the stud outwards,
thereby connecting the sleeve R. with the reciprocating lever V1 by which the flyer
is operated in the manner as before described.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a printing machine the sheet delivery apparatus placed above the impression
'cylinder and made to move in a straight line towards or from the impression cylinder
for the purpose as hereinbefore set forth.

page_text: 2. The combination of a sliding sleeve R. with the flyer C. and lever V' substan-
tially in the manner and for the purpose hereinbefore described.
3. The combination of the delivery apparatus with the upright sliding bars G.
levers K and M. and shaft L. substantially in the manner and for the purpose herein-
before described.
