JAMES
DIXON ASQUITH, Morley, near Leeds, in the County of Yorkshire,
Machinist, do hereby declare the nature of this invention to be as follows:-
The object of my Invention, is to produce an improved wrought iron pulley.
In the pulleys of that class, the arms are fitted into the boss in most cases, and
the reverse ends of the arms are then rivetted to the rim.
The strain put upon them by a belt, and also the vibration often caused in driving
the pulleys, have a tendency to loosen the arms both from the boss and the rim,
and in cases when this occurs, the pulleys have to be removed from the driving
shaft, and have to be repaired.
In carrying out this Invention, a metal boss is used in one or two parts, and also
a metal rim in one or two parts as required. On each side of the boss, a required
number of slots are made corresponding to the number of arms to be put in the
pulley. These slots run down the sides of the boss from the outer to the inner
edge. A required number of metal castings in the form of a T are fixed to the
under side of the pulley rim by bolts or by other means, being put in such a
position that each casting comes directly opposite a pair of the slots that are in the
boss. I do not confine myself to castings in the form of a T, as I can use other
shapes. The arms of the pulley are made preferably of flat bar metal, of such a
width that they fit into the slots in the boss. The required number of arms are put
into the slots in the boss, on both sides, being therefore in pairs; bolts are then
put through the arms on one side of the boss, then carried through the boss, and
through the arms on the other side of the boss, and nuts are then screwed tightly
upon the bolts, and the boss and arms are thus kept in a very firm position. The
reverse ends of the pairs of arms are fixed one on each side of the lower part
of the T castings, and bolts are put through the arms and castings and firmly
secured by nuts, as is done with the boss and arms.
It will be obvious that in this Invention, in cases where an arm or a casting
should become loose, it can easily be tightened again or replaced, without the
necessity of removing the pulley from the shaft.

JAMES DIXON ASQUITH, Morley, near Leeds, in the County of Yorkshire,
Machinist, 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 :-
The object of this Invention is to produce an improved pulley.

page_text: Figure 1 shows a side view of the metal boss of the pulley, having a number
of slots in it.
Figure 2 is a sectional view of the boss of the pulley.
Figure 3 is a view of a T casting to be fixed to the under side of the rim of
the pulley.
Figure 4 is a view of an arm.
Figure 5 is a view showing the manner of fixing a pair of arms to the T casting,
and also to the boss.
Figure 6 is a view of one side of the pulley showing the various parts, as bolted
together.
In carrying out this Invention a metal boss A, in one or two parts is employed,
having a required number of slots a¹, these slots running down each side of the
boss A, and corresponding in number to the number of arms to be put into the
pulley.
A metal rim B in one or two parts is used, and to the inner or under side of this
rim B a required number of T castings C, are fixed by bolts or by other means, being
put in such positions that each T casting comes directly opposite a pair of the
slots a that are in the boss A.
A number of arms D, made preferably of flat bar metal, of such a width that they
fit into the slots a¹ of the boss A, are used in pairs. One end of the arms D are put
into the slots a³, and bolts d', are then put through the arms D, on one side of the
boss A, then carried through the boss A, and through the arms D on the other side
of the boss A, and nuts are then screwed upon the bolts. The reverse ends of the
arms D, are fixed one on each side of the lower part of the T castings C, and
bolts d², are put through the arms D, and T castings C, and secured by nuts, in a
similar manner as the boss A, and the arms D, are secured together.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is:
In driving and other Pulleys, the employment of the boss A, having a required
number of slots a¹ upon each side; the T castings C in combination with the rim B;
the loose arins D, the bolts d', and the bolts d²; the whole of the said parts being
fastened together, and forming a Pulley, as described.
