Improvements in Hard Waste Breaking Machines.
We ABRAHAM ROBERTSHAW of the firm of A. Robertshaw and Sons, Manu-
facturer, and JAMES SCHOLES KAY, Hard Waste Breaker, both of Mytholmroyd
in the County of York do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to be able to reverse the feed rollers in hard waste
breaking machines without having to stop the machines.
Upon the side or horizontal shaft of a hard waste breaking machine for each feed
roller we attach two mitre or bevel wheels, one of which (when the feed roller is in
motion) gears with a similar gear wheel on the ordinary carriage, this carriage
carries a friction wheel which drives, by means of a friction pulley all the gearing
of the various feed rollers; upon wishing to reverse the rollers, the ordinary lever
now used, operates the carriage which brings the gear wheel upon the carriage into
gear with the other gear wheel upon the side or horizontal shaft, at the same time
bringing the friction wheel into contact with a second friction pulley, and so
immediately reverses the motion of the feed rollers.

COMPLETE SPECIFICATION.
Improvements in Hard Waste Breaking Machines.
We ABRAHAM ROBERTSHAW Manufacturer of the firm of A. Robertshaw and
Sons and JAMES SCHOLES KAY, Hard Waste Breaker, both of Mytholmroyd in
the County of York, 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 our invention is to be able to reverse the feed rollers in hard waste
breaking machines, without having to stop the machine.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of part of a hard waste breaking machine with our
improvements applied.
Upon the side or horizontal shaft A, of a hard waste breaking machine B in
any suitable position, we fix two mitre or bevel wheels C and D, a gear wheel E,
upon the ordinary carriage F, gears with the wheel Cupon the horizontal shaft A,
and is driven by means of the ordinary friction wheel G, receiving its motion from
the friction pulley H, on the cylinder shaft H' of the breaker, so driving the
horizontal driving shaft A, which by means of the gear wheels M and J operates
the various feed rollers for feeding the waste through the breaker.
Upon wishing to reverse the feed-rollers from any cause, the ordinary lever K is
operated moving the carriage with gear wheel E into gear with the other wheel D
upon the horizontal shaft A, simultaneously bringing the friction wheel G into gear
with the second friction pulley L, which immediately reverses the motion of the
horizontal driving shaft A, and by means of the various gearing the whole of the
feed rollers throughout the machine.

page_text: This friction pulley L is operated from the cylinder shaft N by means of
pulleys P and P1 and band or strap R or in any other suitable manner."
The cylinder shafts H' and N are driven by means of pulleys S and strap or belt,
from the main driving pulley or shaft.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In hard waste breaking machines, the use and employment of gear wheel D
and friction pulley L or their equivalents operated as and for the purposes, such as
shown and described.
