PROVISIONAL SPECIFICATION.
Improvements in Speed Cone Pulleys.
I, PETER AUGUSTUS RANSOм, of Hyde Road Engineering Works, West
Gorton, Manchester, in the County of Lancaster, do hereby declare the nature of
this invention to be as follows: :-
This invention relates to speed cone pulleys or what are sometimes known as.
step-cone pulleys.
Heretofore such pulleys have been usually made of cast iron in which case
they are made whole in one casting, but sometimes a number of independent.
wrought iron pulleys of different diameters have been placed side by side on the
shaft so that they could be used as a step-cone pulley.
According to my invention I construct a speed cone pulley having wrought.
iron or steel rims and spokes, and a long undivided cast boss or hub, common
to all the rims. I may make the pulley whole or in halves as may be required, and
in the latter case I may secure the halves together by bolts in the well known
manner. In some cases I cast the boss with splitting plates in the manner ordinarily
adopted for split cast pulleys.
I prefer to round the edges of the rims so as not to cut or injure the belt.
With pulleys constructed as above described, there is no chance for the belt to
creep up the side of the steps as is the case with some cast speed cones as usually
made.

Improvements in Speed Cone Pulleys.
I, PETER AUGUSTUS RANSOM, of Hyde Road Engineering Works, West
Gorton, Manchester, 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 :-
This invention relates to speed cone pulleys or what are sometimes known as
step-cone pulleys.
Heretofore such pulleys have been usually made of cast iron in which case
they are made whole in one casting, but sometimes a number of independent
wrought iron pulleys of gradually increasing diameters have been placed side by
side on the shaft so that they could be used as a step-cone pulley..
According to my invention. I construct a speed cone pulley having wrought iron
or steel rims and spokes, and a long undivided cast boss or hub common to all the
rims.
Referring to the accompanying drawings
Figure 1 is a longitudinal central section of a pulley constructed according to my
invention.
Figure 2 is an end view of one half of the pulley.
A is a long cast boss; B, B are wrought iron or steel rims independent of
each other but secured by the arms C, C to the boss A which is common to all

page_text: the rims. The rims C, are of gradually increasing diameter and thus form a
step-cone pulley. The arms may be secured to the rims and to the boss in any
well known manner. The boss is preferably cored out larger in the centre as
shown so as to bear on the shaft at each end only. I have shown a split pulley
the two halves of the boss being secured by bolts D in the usual manner. The
halves of the rim are secured by plates E and bolts or rivets F. In some cases
I cast the boss with splitting plates in the manner ordinarily adopted for split cast
pulleys.
I prefer to round the edges of the rims so as not to cut or injure the belt.
With pulleys constructed as above described, there is no chance for the belt to
creep up the side of the steps as is the case with some cast speed-cones as usually
made.
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 :-
A speed cone pulley constructed substantially as described with reference to the
