I WILLIAM LAWIES JACKSON of Allerton Hall Chapel Allerton near Leeds in the
County of York Member of Parliament do hereby declare the nature of my
Invention for IMPROVEMENTS IN LEATHER SCOURING AND HIDE DRESSING
MACHINERY and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement reference being had to
the accompanying Drawings and to the letters and marks thereon:-
The object of my Invention is to produce a more uniformly sensitive pressure of
the sleekers and setting stones or tools, [which may also be readily reduced or
increased (on the hides or leathers)] of machines employed for leather scouring
and hide dressing than hitherto; and has reference more especially to a machine
entitled a new and useful machine which may be employed for scouring sleeking
or setting hides or leather for which Letters Patent were granted to Edward
Fitzhenry dated 10th September 1866 and numbered 2325.
In the above mentioned machine the sleekers and setting stones or other tools
are carried ench from the free end of a hinged arm and are pressed against the
hide or leather to be operated upon by means of curved flat springs. In practice
it is found that these flat springs are liable to be broken and do not allow of the
pressure being so readily adjusted as is desirable, nor with that degree of regularity
necessary for the perfect working of the machine.
Now in my Improvements I employ buffers between the rocker plate and the
hinged arms carrying the sleekers or setting stones. Such buffers may be formed
of spiral springs or india rubber of suitable quality, and are by preference inounted
on the adjustable rods through which motion is transmitted from the rocker plate
to the hinged arms carrying the sleekers or setting stones. The carriage or bent
flat springs employed in the hereinbefore mentioned machine may be used in
combination with the buffers though not necessarily so.
Other parts of the machine may be constructed in the manner described and
shewn in the Specification of Fitzhenry's Patent above mentioned.
And in order that my Invention may be more readily understood reference is
given to the accompanying Drawings and to the letters and marks thereon.

page_text: DESCRIPTION OF DRAWINGS
Fig. 1 is a longitudinal section and Fig. 2 an end elevation of the carriage of a
machine for leather scouring and hide dressing constructed in accordance with my
Invention.
a represents the frame or sides of the carriage which is or are mounted on the
slide bars b. c is the rocker plate which is hinged on the shaft or pin & the latter
fitting into bearings in the sides or frame a. By means of the connecting rod e
actuated from a rotating crank the carriage is caused to move backwards and
forwards on the slide bars and at the same time a oscillating motion is imparted
to the rocker plate. fare the hinged arms carrying the sleekers or setting stones.
These are connected to the rocker plate c by means of the adjustable bolts g. On
these adjustable bolts g I mount the buffers h which may be made of spiral springs
as in the Drawings or formed of india rubber or other like elastic material, i, i, are
the coach springs which may be used in combination with the buffers h though not
necessarily so.
Having now particularly described and ascertained the nature of my Invention,
and in what manner the same is to be performed I declare that what I claim is:
1° The arrangement and application of the buffers or springs h substantially as
and for purposes herein set forth.
2° The arrangement and application of the buffers h in combination with the
various parts forming the machinery for leather scouring and hide dressing
substantially as and for purposes herein set forth.
