PROVISIONAL SPECIFICATION.
Improvements in or relating to Paper Machines.
1, CHARLES ROBERT SEDDON of 285 Rochdale Road, Bury in the County of
Lancaster, Manager, do hereby declare the nature of my said invention to be
as follows:-
This invention refers to improvements in or relating to paper machines and is
designed to produce a differential motion whereby variable lengths of shake may
be produced by shake rail without stopping or interfering with length of stroke
from connecting rod, which gives a constant motion to end of lever for operating
shake. This I carry into effect by mounting the lever for operating shake in an
adjustable fulcrum mounted on a screwed spindle in a suitable fixing, and which
may be lengthened or shortened by means of a hand wheel or its equivalent while
the machine is working, thus allowing of the shake being altered to the greatest
nicety according to the class of paper being manufactured. The adjustable
fulcrum is of such a form as to allow of the oscillating movements of the shake
lever, and is provided with means for locking the saine in position after being set.
The shake rail is provided with a lever pivoted to a fixing mounted on the floor or
otherwise.

COMPLETE SPECIFICATION.
Improvements in or relating to Paper Machines.
1, CHARLES ROBERT SEDDON of 285 Rochdale Road, Bury in the County of
Lancaster, Manager, do hereby declare the nature of my 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 refers to improvements in or relating to paper machines and is
designed to produce a differential motion whereby variable lengths of shake may
be produced by shake rail without stopping or interfering with length of stroke
from connecting rod, which gives a constant motion to end of lever for operating
shake. This I carry into effect by mounting the lever for operating shake in an
adjustable fulcrum mounted on a screwed spindle in a suitable fixing, and which
may be lengthened or shortened by means of a hand wheel or its equivalent while
the machine is working, thus allowing of the shake being altered to the greatest
nicety according to the class of paper being manufactured. The adjustable
fulcrum is of such a form as to allow of the oscillating movements of the shake
lever, and is provided with means for locking the same in position after being set.
The shake rail is provided with a lever pivoted to a fixing mounted on the floor or
otherwise.

page_text: A is the shake of a paper machine; B the shake lever, and C the connecting
rod for operating the shake lever B from an eccentric or crank operated from any
convenient position. The lever B is attached to the shake A of the paper
machine by the centre D, and is mounted in the adjustable fulcrum E. The latter
is disposed on the screwed spindle G mounted in the fixing H. The upper end of
the screwed spindle G is fitted with the bevel wheel I in which gears the bevel
wheel J on the shaft K mounted in the fixing L on the upper side of the fixing H.
The shaft K is rotated in either direction by the hand wheel M to raise or lower
the fulcrum E according to the amount or length of motion to be given to the
shake A according to the class of paper being manufactured. After the desired
amount or stroke of shake A has been determined upon the adjustable fulcrum E
is locked in position by the nut N. If desired the lever B may be attached to
the fixed fulcrum D as in Fig. 3; the differential motion of the shake A being
effected by the sliding fixing E mounted on the screwed spindle G in the end of
the shake rail A.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what. I
claim is :-
-
The respective combinations and arrangements of apparatus for operating and
giving a differential motion to shake rail of a paper machine, substantially as
described and as illustrated in the annexed drawings.
