PROVISIONAL SPECIFICATION.
Improvements in Machinery for Rubbing Leather into a Round
Section for Boot Laces, Machine Bands, and other purposes in
which Round Leather is required.
I, CHARLES HENRY AVERILL of the Leather Lace Works Vincent Parade
Balsall Heath in the County of Worcester Leather Merchant and Leather Lace
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention consists in employing two or more eccentrics which work upon a
top and bottom shaft the bottom shaft being worked by an arrangement of cogs
from the top shaft.
To these eccentrics are attached arms carrying plates working one over the
other the under plate being made slightly concave on its face and the upper one
convex.
Thus when the shaft is set in motion the eccentrics cause the plates to slide
backwards and forwards one over the other and the leather having been placed
between them is rubbed into a round section. The leather to be operated upon
may be passed into the machine either from the front or from the back.
Both the upper
& lower plates may move or the one plate be stationary.
Suitable springs are placed under the bottom plate in order to form a pliable bed
or if preferred the springs may be attached to the upper plate and the pressure
upon the leather is varied as required by tightening or slackening the springs.
A similar result may be obtained by using a cranked shaft instead of the
eccentrics and attaching the arms to the cranks.
This machine will be of great advantage in forming any round substances of
leather such as boot laces, machine bands, driving reins dog slips & collars and
such like.

SPECIFICATION.
Improvements in Machinery for Rubbing Leather into a Round
Section for Boot Laces, Machine Bands, and other purposes in
which Round Leather is required.
I, CHARLES HENRY AVERILL of the Leather Lace Works, Vincent Parade
Balsall Heath in the County of Worcester, Leather Merchant and Leather Lace
Manufacturer, do hereby declare the nature of this invention 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 annexed drawings and to the
figures and letters shewn thereon:-
Similar letters of reference relate to similar parts in the figures.
This invention relates to the above named machinery and consists in employing
two or more eccentrics which work upon a shaft or shafts supported by bearings
upon the machine.
To the eccentrics are attached arms carrying plates which work the one over the
other the under plate being slightly concave on its face and the upper one convex.
These plates are finely corrugated or roughened in the direction of their length in
order to obtain a good grip of the leather when being rubbed.
When the shaft or shafts are set in motion the eccentrics cause the plates to slide

page_text: backwards and forwards the one over the other and the leather lace, thong, or
other article being made is placed between the plates and is rubbed into a round
section..
Both the upper and lower plates may move or the one plate be stationary,
suitable springs may be placed under the lower plate in order to give a pliable bed
or if preferred the springs may be connected to the upper plate and swinging frame
that carries the same and the pressure upon the leather can be varied and adjusted
as required by tightening or slackening the springs by means of screw nuts or other
"suitable method.
When heavy work is being turned out and extra power is required. I attach
under the table of the machine a second shaft carrying eccentrics and supported
by bearings, in this case a toothed wheel will be fixed upon the upper shaft and a
corresponding toothed wheel upon the lower or second shaft; these toothed wheels
gear into each other, the machine may be driven by any suitable driving power,
by a band from the driving wheel, upon the upper shaft, or from a driving wheel,
upon the lower shaft, the action will be the same in either case, the driving wheel
may be upon any convenient part of the shaft either outside the frame of the
machine or within the same.
Similar arms as the first are connected to the second set of eccentrics; these arms
being attached to the under plate, so that by the use of two sets of gearing, double
power is obtained where extra pressure is required.
In this case the under plates will be supported, and may slide to and fro, upon
the bed of the table, which is cut out for that purpose.
Figure 1, is a front, or end view, of the machine.
Figure 2, a side view, of the same.
Figure 3, is a front,, or end view, shewing the double set of gearing.
Figure 4, a side view of same.
A are the supports of the machine, B, B1, the eccentrics upon the shaft C,
D, D are the arms attached to-the-upper plates E, E, F, Fare-the-lower-plates
either stationary or moveable, G G springs to give the pliable bed; H-is-the
frame, or support of the upper- plate, attached to a moving bar I, having:bearings
upon the upper portion of the machine, these bearings can be adjusted by screw
nuts J, JK is the wheel upon the, shaft over which the driving band K¹ passes,
to actuate the machine.
Operation. The leather-to-be-operated-upon is_passed into the machine, either
from the front, or from the back, between the upper, and lower, rubbing-
plates EF. EF, the plates as before stated being corrugated receive the
leather, and the backward, and forward, motion of the plates, roll,_or_rub,_the
leather into a round section.
Referring to Figures 3 and 4, in which the two shafts and double arrangements
of gearing, is illustrated B, B1, are the second pair of eccentrics, upon the
shaft C, B, D, are the arms attached to the lower plates F, F, which in
this case may be moveable the same as the upper ones, L, is a cog wheel upon
the shaft C, gearing into the cog wheel L', upon the upper shaft C, M, is a
wheel.upon the shaft C', to which the driving power may be connected instead of
the upper wheel K, if preferred.
Springs may-be-used-or-not,_in_connection with the upper, and lower, plates if
required, to give extra pliability. These are not shewn, as they will-be-applied
in a similar manner to that set forth in Figures 1, and 2; and the description
relating to same.
The operation of the machine in this case, will be precisely similar to the first
described, except, that double power, and pressure, can be obtained in nubbing, the.
leather, when heavy work is being turned out.
As an alternative,, to the above method, of using rubbing plates, I can when
desired, use in the place of the upper plate; or plates, a barrel, or banrels, or
rollers, which can be made to revolve or turn in a concave under plate, the leather
will be received in the same manner and rolled, or rubbed, into a round section.

page_text: may
Or instead of using eccentrics upon the shaft, or shafts, of the machine, I
when preferred obtain a similar result of working by the use of a cranked shaft
or shafts.
By the use of my machine, great advantages are gained in turning out rounded
substances, or articles of leather, such as boot laces, machine bands, driving reins,
dog slips, and collars etc.
'
I wish it to be understood, that I do not confine myself to the herein specific
details of construction, as I may as occasion may demand, vary the same without
departing from the main principle of this my invention.
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,
First. The general arrangement, and combination of the various parts, shewn
in Figures 1, and 2, or any mere equivalents thereof, constituting my improve-
ments in machinery for rubbing leather, into a round section, substantially in
manner as herein more fully set forth and specified.
Second. I claim, the general arrangement, and combination, of the various parts
shewn in Figures 3, and 4, or any mere equivalents thereof, constituting my
improvements in machinery for rubbing leather into a round section, substantially
in manner as herein more fully set forth and described.
