PROVISIONAL SPECIFICATION.
Improvements in Roller Hardeners for the Manufacture of Felt.
I WILLIAM GAINES BYWATER of Sweet Street Foundry, Leeds in the County
of York, Machine Maker do hereby declare the nature of this invention to be as
follows:-
The present improvements consist in reducing the number of driving shafts &
wheels which are used in the roller hardeners as at present constructed, and so
obtaining greater simplicity, and requiring less driving power. The machine as
at present constructed is generally driven as follows. First a main driving shaft
extending across the machine, which drives a shorter shaft placed at right angles
to it, by means of a larger bevel wheel driving a smaller one, and then a larger
spur wheel on the shorter shaft driving a smaller wheel on the excentric shaft
which is in a line with the shorter shaft. And in machines in which an excentric
shaft is used on each side, they are connected by means of bevel wheels and a
shaft which is immediately over, and in a line with the main driving shaft.
In these present improvements I propose to dispense with the present main
driving shaft, the shorter shaft, and the wheels which gear them together and to
the excentric shaft, and utilize the present shaft which connects the two excentric
shafts, as the main driving shaft.

COMPLETE SPECIFICATION.
Improvements in Roller Hardeners for the Manufacture of Felt.
I, WILLIAM GAINES BYWATER of Sweet Street Foundry Leeds in the County
of York, Machine Maker, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The present improvements consist in reducing the number of driving shafts and
wheels which are used in the roller hardeners as at present constructed, and so
obtaining greater simplicity and requiring less driving power. The machine as at
present constructed is generally driven as follows. First, a main driving shaft
extending across the machine which drives a shorter shaft placed at right angles to
it by means of a larger bevel wheel driving a smaller one, and then a larger spur
wheel on the shorter shaft driving a smaller wheel on the excentric shaft which is
in a line with the shorter shaft. And in machines in which an excentric shaft is
used on each side, they are connected by means of bevel wheels and a shaft which
is immediately over and in a line with the main driving shaft.
In these present
improvements, I propose to dispense with the present main driving shaft, the
shorter shaft, and the wheels which gear them together, and to the excentric shaft,
and utilize the present shaft which connects the two excentric shafts, as the main
driving shaft. In order that this invention may be better understood and carried
into practical effect, I have added a sheet of drawings illustrative of the same of
which the following is a description.
Fig. 1 is a front elevation of the machine.
Fig. 2 is a plan of the same.

page_text: into a number of excentrics corresponding with the number of rollers B. These
shafts Care driven by means of bevel wheels D and main driving shaft E to which
the driving pulley is attached. A worm G is fixed on the driving shaft E and
gears into a worm wheel H and through the wheels J, shaft K and bevel wheels L
gives rotary motion to the rollers A. Thus rotary motion is given to the rollers A
and a to and fro motion is given to the rollers B from one driving shaft E, which
arrangement gives greater simplicity in constructing such felt hardening machine,
and requires less horse power to drive it than hitherto.
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―
The method of construction by which one driving shaft E is made to give rotary
motion and a to and fro motion to the rollers in a felt hardening machine
substantially as herein set forth and described.
