PROVISIONAL SPECIFICATION.
Improvements in Machine Rollers for Rolling Leather and other
like Materials, also applicable to Wringing and Mangling
Machinery.
I, CHARLES WHITFIELD of Kettering in the County of Northampton, Engineer
do hereby declare the nature of the said invention to be as follows:-
The object of this invention is so to mount the top roller bearings in this class of
mechanism that the pressure of the springs or weights shall only be exercised upon
the top roller during the actual rolling operation and shall discontinue and be
removed therefrom the instant such operation is completed.
In performing my invention and whereas in rolls employed for rolling leather and
other like materials a pair of side rods are employed for each top bearing I carry
the same upwards through the top plate and suspend them therefrom by means of
adjustable lock nuts. I also provide additional lock nuts or sleeves upon the
length of the said rods to press upon the top bearings whilst their lower extremities
are connected to a cross-bar or block fitting loosely into a suitable recess formed in
the frame side. This cross-bar in turn is connected by a single central rod with
the spiral volute or other spring or weighted lever employed for imparting the
required pressure.
As applied to wringing and mangling machines instead of suspending the rod
which connects the top roller bearing to the spring or weighted roller as heretofore
I carry the same upwards through a top plate and suspend it therefrom by means
of an adjusting nut or pair of lock-nuts.
In this manner I am enabled to leave a little play between that part of such rod
which rests upon the top bearing and the top bearing itself and thus I ensure that
the top roller will have to lift a proportionate distance before, the pressure of the
springs or weights come upon the rollers as aforesaid.

COMPLETE SPECIFICATION.
Improvements in Machine Rollers for Rolling Leather and other
like Materials,, also applicable to Wringing and Mangling
Machinery.
I, CHARLES WHITFIELD, of Kettering, in the County of Northampton, Engineer,
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 :-
The object of this invention is to so mount the top roller bearings in this class of
mechanism that the pressure of the springs or weights shall only be exercised upon
the roller during the actual rolling operation and shall discontinue and be removed
therefrom the instant such operation is completed.
In order that this invention may be more readily understood and carried into
practical effect I have hereunto annexed a sheet of drawings illustrative of my
improvements and will now proceed to describe the same with the assistance of the
various figures and letters of reference marked thereon.
Fig. 1 is a front elevation of a machine for rolling leather and
Fig. 2 is a transverse sectional view of one of the frame sides on line a-b.

page_text: In accordance with my invention and as applied to rolls for rolling leather and
other like material a pair of side rods A. A. are employed for each top bearing B. B
which are carried upwards through the top plates C. C. and suspended therefrom
by means of the adjustable lock nuts D. D.
I also provide additional lock nuts E. E upon the said rods to press upon the top
bearings whilst the lower extremities of these. rods are connected to a block
or cross bar fitting loosely into a suitable recess formed in the frame-side.
F
This cross bar in turn is connected by a single central rod G with the volute
spring H or other equivalent means for imparting the required pressure, the tension
of which spring is adjusted by the nut I.
By so mounting the top bearings it will be seen that the pressure of the springs
during the rolling operation is on the top roller bearings B. B, but as soon as such
operation is completed the pressure is instantly removed and transferred to the
top plates C. C.
Instead of the lock nuts E. E. a pair of tubes or sleeve pieces J. J. might be
employed (as shewn in Fig. 3) which bear against the top bearing and extending
upwards are rather shorter in length than the distance between the bearing and the
lock nuts D. D. as illustrated.
These tubes or sleeve pieces operate in a similar manner to the lock-nut arrange-
ment, for when the rolling operation commences the rising up of the top roller
bearing will cause such tubes to press against the lock-nut D. D and bring the
pressure of the spring into play.
As applied to wringing and mangling machines instead of suspending the rod
which connects the top roller bearing to the spring or weighted roller as heretofore
I carry the same upwards through a top plate and suspend it therefrom by means
of an adjusting nut or pair of lock-nuts.
In this manner I am enabled to leave a little play between that part of such rod
which rests upon the top bearing and the top bearing itself and thus I ensure that
the top roller will have to lift a proportionate distance before the pressure of the
springs or weights come upon the rollers as aforesaid.
Having thus particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is.
1st. In machines for rolling leather and other like materials the employment of
side rods A. A. cross bar F, lock nuts D. D. and E E, central rod G, and volute
spring or other equivalent mechanism all mounted and operating substantially as
and for the purpose herein before described and illustrated on the accompanying
drawing.
2nd. The improvements in wringing and mangling machines substantially as set
forth.
