Improvements relating to Sheet Adjusters for the Delivery Tables
of Printing Machines.
We, WILLIAM HENRY SPELMAN, of the Clarendon Rooms, South John Street,
Liverpool, Printing Works Proprietor, and THOMAS EDWARD DELAFONS, of 23, Teilo
Street, Liverpool, Printers' Engineer, do hereby declare the nature of the said
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 apparatus for adjusting sheets of paper as they are
delivered on the delivery tables of printing machines by the gate or flyer of the
machine, so that an even pile is formed.
Apparatus according to this invention is illustrated in the accompanying drawings,
in which Figure 1 is a plan and Figure 2 an end view.
The delivery table, A, has formed in it four grooves a, which radiate at right
angles to each other. Within such grooves are disposed rods b, c, d, e, three of
which are moveable whilst the fourth rod, e, is fixed. Adjustably clamped to the
rod e is the stationary back board or gauge f, whilst the board g is mounted on
the moveable rod b. On the rods c and d are clamped the flanged brackets h and i.
The sheets of paper, as they are delivered by the flyer, fall within the space bounded
by the boards f, g, and the brackets h, i, and are beaten or knocked up against the
stationary board f by the board g and brackets h, i, to which motion is imparted as
follows. A tappet lever j is mounted in the bracket k on the side of the table next
to the flyer shaft. Swivelled to the lower end of said lever are two links 1, whose
free ends are slotted so as to hook over a pin m on the bracket b¹ of the rod b. The
free end of the lever j is depressed by a tappet or roller on the flyer shaft each time
the flyer delivers a sheet. The lever j, as it is depressed, thus withdraws the
board g from the pile of paper, and the return or beating up motion is derived from
the spring g¹. Upon the rod b are formed two inclined surfaces n, which abut
against and push apart the rods c and d when the rod b is withdrawn by the lever j.
The return movement or beating up motion of the rods c and d and the brackets h, i,
is derived from the springs h¹, ¹.
It will thus be seen that as the rod b and board g are withdrawn by the tappet
lever j, the rods c, d, and brackets h, i, are also pushed apart, these movements just
preceeding the delivery of a sheet by the flyer. As the flyer rises, the lever ; is
released, and the board g and brackets h, i, are caused, by means of their
springs g¹, h¹, ¹, to knock up against the pile of sheets on the table.
By lifting the connecting links from the pin m, the lever j is disconnected from
the rod b, whereby the apparatus can be entirely and instantly placed out of gear
when required.
The boards f, g, and brackets h, i, are each adjustable upon their rods, so as to
accomodate different sizes of sheets.
It will be noted that the beating-up motions above specified are performed
by springs. In this way is obviated a disadvantage attending those machines
wherein the beating-up boards are pushed against the paper pile by rigid rods and

page_text: levers, namely the liability of fracture to such rigid connections when a rigid pile of
several reams is being dealt with.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we would here state that
we are aware that it is not new to actuate beating up devices from a flyer shaft and
by springs, and we declare that what we claim is:=
1. Sheet adjusting mechanism wherein motion is transmitted from a flyer shaft to
beating-up devices by a tappet and tappet lever such as j, the latter being coupled to
such beating up devices by slotted links, such as l, engaging with a pin, m, whereby
the said lever and beating up devices may be readily placed out of gear by
uncoupling said links, substantially as described with reference to the drawings
hereto annexed...
2. Sheet adjusting mechanism wherein the carrier rod of one of three beating-up
devices is formed with inclined surfaces against which the ends of the carrier rods
of the other two beaters abut, whereby as the first carrier rod is withdrawn the said
inclines force apart the other carrier rods, the return or beating up motions of said
devices being effected by springs, substantially as described with reference to the
drawings hereto annexed.
-
3. The arrangement, combination, and disposition of parts, forming sheet adjusting
mechanism, substantially as described with reference to the drawings hereto
annexed.
