PROVISIONAL SPECIFICATION.
Improvements in Scutchers for Cotton and the like.
I ALFRED BRADSHAW of the Albion Mills, Ashton-under-Lyne, Overlooker do
hereby declare the nature of my said invention to be as follows:-
These improvements refer to the beater bars employed in scutchers to form the
segmental grating or grid between which the dust &c. passes or escapes during the
scutching of the cotton fibre. Hitherto these bars have been mounted separately in
the segmental grooves or circles affixed to the inside of the framework and thus have
had to be adjusted separately.
Now this invention consists in providing means whereby all the beater bars are
connected to a single actuating rod and thus can all be moved together and adjusted
simultaneously and with proportionate openings between the said bars-wider at the
top and gradually closing in more and more towards the bottom bar. In performing
my invention I provide one of the axles of each beater bar with an arm of pro-
portionate length according to its position, and the extremity of which is jointed or
slotted so as to embrace a pin or stud projecting from the side of the actuating rod
hereinbefore mentioned. The lower end of the actuating rod is in turn connected by
a suitable connecting rod to an eccentric mounted in a bracket and the spindle or axle
of which eccentric passes through the side of the framework and is there provided
with a lever handle or hand-wheel conveniently disposed for operating the eccentric.
By now turning the eccentric more or less upon its axis a proportionate motion will
be simultaneously imparted to each of the beater bars-according to the length of its
actuating arm (connecting it with the actuating rod hereinbefore described) and then
by screwing up a single set-screw in the eccentric bracket I an enabled to affix the
said eccentric in position and by the same movement to lock all the beater bars in their
relative positions simultaneously.
In this manner I effect not only a saving of all the time hitherto occupied in
adjusting the beater bars but am also enabled to adjust the said bars whilst the
scutcher is in motion.

COMPLETE SPECIFICATION.
Improvements in Scutchers for Cotton and the like.
I, ALFRED BRADSHAW of the Albion Mills, Ashton-under-Lyne, Overlooker 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:-
1
These improvements refer to the beater bars employed in scutchers to form the
segmental grating or grid between which the dust &c. passes or escapes during the
scutching of the cotton fibre. Hitherto these bars have been mounted separately in
the segmental groove or circles affixed to the inside of the framework and thus have
had to be adjusted separately..
Now this invention consists in providing means whereby all the beater bars are
connected to a single actuating rod and thus can all be moved together and adjusted
simultaneously and with proportionate epenings between the said bars-wider at the.
top and gradually closing in more and more towards the bottom.
In performing my invention instead of mounting the ends of the beater bars a, a
го

page_text: so as to be clamped fast by the set screws b. b as heretofore I mount the ends of each
of the bars in the brackets c. c as illustrated so as to be capable of turning therein as
upon an axis and 1 provide each beater bar with an arm d. of proportionate length
according to its position and the outer extremity of which arm is jointed or slotted so
as to embrace a pin or stud e projecting from the side of the actuating rod f. The
lower end of this actuating rod is in turn connected by a suitable connecting rod g
to an eccentric / working in a bracket (shewn dotted in Fig. 1), affixed upon the
outside framework of the scutcher and the spindle or axle of which eccentric passes
through such framework and is there provided with a hand-wheel j conveniently
disposed for operating the eccentric.
By now turning the eccentric more or less upon its axis a proportionate motion
will be simultaneously imparted to each of the beater bars-according to the
length of its actuating arm, and then by screwing up a single set screw k in the
eccentric bracket I am enabled to affix the said eccentric in position and by
the same movement to lock all the beater bars in their relative positions
simultaneously.
To more readily adjust the beater bars, I provide the hand wheel ; with an index
finger or pointer and to the frame-side I affix a segmental index m, so that by
observing the position of the pointer 1, the bars can be adjusted to the greatest
nicety.
In this manner I effect not only a saving of all the time hitherto occupied in
adjusting the beater bars but am also enabled to adjust the said bars whilst the
scutcher is in motion.
Having thus 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 improved combination and arrangement of mechanism for facilitating the
adjustment of all the beater bars in a scutcher simultaneously, substantially as berein-
before described and illustrated on the accompanying drawing.
