Improvements in connection with Feed and Delivery Boards of
Printing Machines.
We, WILLIAM HENRY DAWSON and ALLAN PARKER DAWSON, of Ashfield.
Foundry, Otley, in the County of York, and JAMES STOTT of the same place,
Printers Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in connection with feed and
delivery boards such as are used on that class of printing machines known as the
"Wharfedale and has for its object, the combination with the feed board of
certain mechanism so arranged that, a perfect register of each sheet is automatically
obtained in a manner that, the speed of the machine may be increased and thus
proportionately increase the output; also to combine with the delivery board
such mechanism as will ensure of a perfect register of the sheets as they are
delivered.
in carrying out the above, we secure the feed board in the manner as hitherto,
and mount to the front edge of same next to the cylinder, a reciprocating lay
having two or more fingers with stop flanges for adjusting the sheet, after it is fed
to the machine. Before the sheet is received by the grippers of the impression
cylinder, the before mentioned lay is automatically moved by a tappet or the like
into a certain position, the reciprocating lay coming in contact with the edge of the
fed sheet, adjusts it to a predetermined position suitable for the grippers of the
cylinder to take hold of same; the sheet being moved to the requisite side
register by a plate operated at or about the same time as the front lay, by a bell crank
lever or other suitable connection. After the grippers take hold of the sheet, the
front lay is moved away from the cylinder by the return movement of the operating
mechanism.
For steep inclined feed boards, the front lay may be hinged to the feed board
and the reciprocating motion to and from the cylinder dispensed with, the lay
being kept in contact with the feed board when required by a spring or the like,
and clear of the cylinder when required by a bowl rotating in contact with the
cylinder or the like, or by a reciprocating bar in connection with the said lay;
and when the cylinder is in the position for the board and lay to receive the sheet, it is
fed thereto and the board raised such a distance that, the end of the lay is projected
into the recess of the cylinder, the flanges at the front edge of the lay supporting
the sheet until the grippers take hold of the same.
The side register may be accomplished as before described, or a fixed side lay
may be utilized with either arrangement of front lay.
When the edge of the sheet is received by the grippers of rotating cylinder, the
front lay is automatically moved clear of the cylinder by the before mentioned
bowl or reciprocating bar.
The delivery board is provided with a number of slot holes, in two or more of
which may be fitted adjustable plates, operated to and from the centre of the
board, the said plates standing vertically from the face of the board and actuated

connecting same to the before mentioned plates.

Improvements in connection with Feed and Delivery Boards of
Printing Machines.
We, WILLIAM HENRY DAWSON, and ALLAN PARKER DAWSON, of Ashfield
Foundry, Otley, in the County of York, and JAMES STOTT, of the same place,
Printers Engineers, do hereby declare the nature of this invention and in what
manner the same is to he performed, to be particularly described and ascertained
in and by the following statement:—
This invention relates to certain improvements in connection with feed and
delivery boards, such as are used on that class of printing machines known as the
"Wharfedale" and has for its bject, the combination with the feed board of
certain mechanism so arranged that, a perfect register of each sheet is automatically
obtained and in a manner that, the speed of the machine may be increased and thus
proportionately increase the output; also to combine with the delivery board
such mechanism as will ensure a perfect register of the sheets as they are
delivered.
In explaining this invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents the plan of a feed board with the registering apparatus
arranged according to this invention.
Fig. 2 is a side view of the same and Figs. 3 and 4 are enlarged details.
Fig. 5 represents a modified arrangement of the front lay reciprocated by an
oscillating lever.
In carrying out the above object we secure the feed board A. in the manner
as hitherto, and mount to the front edge of the same next to the cylinder, an
oscillating lay shaft or bar B. having two or more lay fingers C. provided with
stop flanges C against which the sheets are laid when fed to the board A.
Before the sheet is fed and received by the grippers of the impression cylinder,
the before mentioned lay stop fingers C. are moved outward to a position somewhat
as shown by Fig. 4 by the operation of bars D. through the reciprocation of the
levers E. secured on oscillating shaft F', the stops D' on the bars D. operate
the bell crank levers G, the stops H' on bars H. draw the said bars and side
register plates P. away from each other; the bars H. H. being connected together
by springs S.
On the retreat of the before mentioned bars D. and by the contraction of the
springs S, the lay stop finger flanges and the side register plates P. move and
adjust the sheet to its predetermined position for the grippers of the impression
cylinder to take hold of same. The front edge of the feed board A. is then raised,
and the fingers C. secured to lay shaft or bar B. supported in the ordinary manner
allow the Hanges C to lower and clear of the cylinder as hitherto, thus bringing
the front edge of the sheet into position for the grippers of the impression cylinder
to take hold of the sheet, after which the feed board is lowered and the front
lay fingers C. moved outwards on the return movement of the levers E. and
oscillating shaft F.
In case the bell crank levers G. are connected by pins to the bars D. and H,
then the springs S. may be dispensed with, the motion of the bars and side register
plates P. being then positive.
The lay stop fingers C. may be operated by an oscillating lever J. mounted cu a

page_text: stud at J, the said lever reciprocating the lay fingers C. to and from the
impression cylinder, the arm K¹ projecting under feed board' A. keeps the feed
board and fingers C. in their required positions in relation to each other. The feed
board A. when the sheet is fed to the grippers is raised and lowered in the
ordinary manner.
For steep inclined feed boards, such as shown by Figs. 6 and 7 representing side
elevations, the front lay shaft or bar B. may be hinged to the feed board A. and
the oscillating or reciprocating motion of the shaft or bar B. and fingers C.
dispensed with, the lay fingers C. being kept in contact with the feed board, that
is the upper surface of the lay fingers C. are kept lineable with the face of the feed
board by springs L. or the like and clear of the cylinder at the required time by a
small bowl or pulley M. rotating in contact with the impression cylinder or the
like, and when the cylinder is in the position for the feed board A. and lay
fingers C. to receive a sheet, the edge of the fed sheet rests upon the flanges C
The front edge of the feed board is then raised such a distance that, the flanges C¹
of the lay fingers are projected into the recess N. of the impression cylinder for the
grippers K. to take hold of the front edge of the sheet, the small bowl or pulley M.
being in the recess N. allows the upper face of the fingers to remain lineable with
the feed board as shown until the grippers take hold of the sheet, then the said
pulley M. on coming in contact with the circumference of the cylinder causes the
ends of the flanges C¹ to be moved away out of the recess N. and clear of the
cylinder.
The small bowl or pulley M. may be dispensed with and the shaft or bar B.
with fingers C. operated by bars D. and levers E. in the manner as before
described. On the bars D. moving in the direction of arrow, the ends of finger
flanges C fall away from the cylinder, the motion of said bars compressing the
spiral spring L. which forces the fingers back to their normal position on the
reversal of the motion of the said bars.
The side register may be accomplished as before described with reference to
Fig. 1 by connecting the same with the bars D.
The arrangement of delivery board is shown in plan view by Fig. 8 and in side
elevation by Fig. 9 which also shows a portion of an ordinary flyer. The delivery
board Y. is provided with a number of slot holes Q. opposite to which, on the
underside of the board are mounted bars R. supported by suitable staple brackets
in a manner that the bars will slide easily through same, or grooves may be formed
in the delivery board for the reception of the said bars to which in either case are
attached adjustable plates T, the ends of the bars being kept in contact with a
compound central cam U. by springs connected to the bars which may be either in
tension or compression, so that on the operation of the central cam U. by the
reciprocating bell crank lever V. and connections, the bars R. and plates T. are
forced outwards for the reception of the sheet, after the delivery of which, on the
return of the central cam U. the before mentioned springs force the bars R. and
plates to their normal position.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is
1. A printing machine feed board A. shaft or bar B. lay fingers C. and bars D.
combined with the levers and mechanism in connection for operating the same,
all arranged substantially in the manner and for the purpose as hereinbefore set
forth.
2. A printing machine feed hoard A. shaft or bar B. lay fiugers C. and bars D.
combined with the levers and operating mechanism, all arranged substantially in
the manner and for the purpose as hereinbefore described.
