PROVISIONAL SPECIFICATION.
Improvements in Friction Gearing for Speed Cones.
We, JOHN DOWNHAM, of Barnbrook Iron Works, Machinist, and JAMES
GARSIDE, of 1 Dawson Street, Draughtsman, both of Bury, in the County of
Lancaster do hereby declare the nature of this invention to be as follows:-
-
Our object is to provide an improved means of communicating motion from one
speed cone to another.
This we accomplish by placing between the cones upon a suitable shaft, or
bearing, a friction wheel of suitable size which can be moved upon the shaft or
bearing to any suitable position upon the cones, for giving any desired rate of
speed, by a screw or other suitable means.

Improvements in Friction Gearing for Speed Cones.
We, JOHN DOWNHAM, of Barnbrook Iron Works, Machinist, and JAMES
GARSIDE, of 1 Dawson Street, Draughtsman, both of Bury, in the County of
Lancaster 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 :-
Our object is to provide an improved means of communicating motion from one
speed cone to another.
This we accomplish by placing between the cones upon a suitable, shaft, or
bearing, a friction wheel of suitable size, which can be moved upon the shaft or
bearing to any suitable position upon the cones for giving any desired rate of speed,
by a screw, or any other suitable means.
Referring to the drawings sent herewith, which give a side view of the best way
of applying our improved apparatus :-
a indicates a suitable speel cone, revolving on shaft 6 in bearings c, beneath this
is placed a similar speed cone d revolving on shaft e in bearings f. Between the
cones a and d is placed the friction wheel g, rotating on bearing or boss 9 2 which
slides upon hollow shaft h within which is a suitable screw h 2 working in a socket
or thread formed in boss 9 2. The hollow shaft is rigidly fixed upon frame i
by means of bosses or bearings k.
By means of the handwheel 3 the screw can be rotated, and the friction
wheel g moved along the parallel surfaces of the cones a and d so as to bring
varying diameters into communication and so give any desired rate of speed.
The shaft e and bearing fare formed to slide upon frame i so that the cone d
may be withdrawn (by means of a screw or other suitable apparatus) from contact
with friction roller g, when it is desired to stop the motion.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1st. The combined apparatus, substantially as described and shown, herein before
and in the accompanying drawings, for the purpose set forth.
2nd. The use of of a friction wheel or roller for communicating speeds between
speed cones, substantially as described and shown hereinbefore and in the
accompanying drawings.
