ISIONAL SPE IFICATION.
An Improved Machine for Preparing Leather Soles, which is also
applicable for other like purposes.
Wo RICHARD LLOYD JOHN MASON YATES, and Louis ALLEN KNIGHT all
of Globe Works Stafford in the County of Stafford, General Engineers, do hereby
declare tho nature of our said invention to be as follows:-
Our invention has for its objeut, an improved machine for preparing leather
soles, which is also applicable for other like purposes by which we cau crimp a
leather sole along its whole length or leave intermediate spaces plain and the other
portions crimpled.
In carrying our invention into practice we mount a fluted brass roller in flexible
bearings in a suitable frame or standard and underneath this fluted roller a plain
roller is mounted in sli ling bearings so as to allow it to move up and down and this
we accomplish by two cains or eccentrics working underneath the slide bearings of
the plain roller mounted on either end of a spindle and operated by a lèver.
The fluted and plain rollers are caused to revolve in opposite directions by
suitable gearing driven by hand or steam power.

An Improved Machine for Preparing Leather Soles, which is also
applicable for other like purposes.
We RICHARD LLOYD JOHN MASON YATES, and LOUIS ALLEN KNIGHT all
of Globe Works Stafford in the County of Stafford General Engineers do hereby
declare the nature of our gaid invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
Our invention has for its object an improved machine for preparing leather soles
which is also applicable for other like purposes by which we can crimp a leather
sole along its whole length or leave intermediate spaces plain and the other
portions crimped.
In carrying our invention into practice we mount a fluted brass roller in flexible
bearings in a suitable frame or standard and underneath this fluted roller a plain
roller is mounted in sliding bearings so as to allow it to move up and down and
this we accomplish by two cams or eccentrics mounted on either end of a spindle
working underneath the slide bearings of the plain roller and operated by a
lever.
The fluted and plain rollers are caused to revolve in opposite directions by
suitable gearing driven by hand or steam power.

page_text: In order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto two sheets of drawings upon which
we have illustrated our improved leather preparing machine.
Figure 1 is a front elevation of our leather preparing machine.
Figure 2 is a plan view of Figure 1.
Figure 3 is an end elevation of Figure 1 showing the driving mechanism.
Figure 4 is a sectional end view taken through the line a. b. on Figure 1.
In carrying our invention into practice we mount the brass fluted roller B in the
frame A in the sliding bearings b and band on the top of these bearings we fix
the coiled or other form of spring which can be adjusted by means of the
handles and so as to regulate the tension on the roller B when the machine is
in operation. Also mounted in the frame A underneath the roller B is a plain
roller D in the sliding, termed at each end of the spindle which is mounted in
bearings and d and these bearings rest upon the cains
or eccentrics f¹ and
fixed bearings. Attached to the end of this spindle is a lever f for operating the
roller D.
The machine is driven by a driving belt passing over the pulley H which is
fastened on one of the ends of the roller B or the machine may be driven by hand
power. Also fastened onto the same end of this roller are the spur wheel and
the pinion wheel which gear into the pinion wheel and spur wheel h' respectively
which are mounted on one end of the spindle S revolving is suitable bearings, fixed
in the extended portion a¹ of the frame. Fixed ou one end of the spindle K is
another spur wheel which gears into the pinion wheel A and on the other end of
this spindle the pinion wheel is fixed gearing into the spur wheel mounted on
the end of the roller D which transmits motion to the said roller. By placing the
fluted roller at the top it prevents the stain which is squeezed out of the leather
from marking the sole when it is being operated upon.
The action of the machine is as follows:-
The leather sole to be operated upon is first placed between the rollers and then
the lever is pulled down which action lifts the bottom roller up against the top one
by means of the cama f' and f" and squeezes the leather sole. The machine is then
set in motion which cause the top and bottom rollers to revolve in opposite directions
thereby drawing the leather sole forward and impressing the ribs or flutes onto the
leather. These impressions can be made at intervals or along the whole length
of the sole as desired by lifting up the lever which action separates the bottom
roller from the top.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improved machine for preparing leather soles and such like purposes
consisting essentially of the top fluted roller such as B mounted in flexible bearings
and the bottom roller such as D mounted in sliding bearings and operated by means
of two cams such as ¹ and for their equivalents in the manner aud for the
purpose substantially as hereinbefore described and shown on the accompanying
sheets of drawings.
