RICHARD BROOK, 11 Disraeli Terrace, Hunslet, Leeds, Pattern Maker, I do hereby
declare the nature of my invention for BREAKING STONE AND CRUSHING ORE &c.,
to be as follows:
.
An improved Frame with bearings for the Butt Jaw Stocks and Crank Lever
Shafts, I fix both swing Jaw Stocks to form a butt-binge on one shaft to hang in
the centre of the top of Frame, at the bottom of Butt Jaw Stocks there is a series
of Toggle groves, a long Crank Lever with a series of Groves, at the Crank end,
and one ordinary Toggle on each side of Crank end of Lever, the other end at the
bottom of the Butt Jaw Stocks, a Spiral Spring to each Butt Jaw Stock for Draw-
back Motion, a connecting Rod at horizontal end of Lever, the other end with a
crank or excentric, with Fly Wheels and Driving Pulley attached, in the end of
frame and Butt Jaw Stocks, I insert loose Jaw faces in halves..
RICHARD BROOK,

page_text: series of toggle groves, a long Crank Lever with a series of groves at the Crank end,
and one ordinary toggle on each side of Crank end of Lever, the other end at the
bottom of the Butt Jaw Stocks for Draw back Motion, a connecting Rod at
horizontal end of Lever the other end with a Crank or Excentric, with Fly Wheels
and Driving Pulley attached, in the end of Frame and Butt Jaw Stocks I insert
loose Jaw faces in halves.
My arrangements are as follows, an improved Frame, Fig. 1. A with bearings
Fig. 2. B for the Butt Jaw Stocks Shaft C, In the centre of the top of Frame A,
and in the centre of bottom of Frame A, are bearings Fig. 3, D for the Crank end
of Lever Shaft Fig. 1, E. I fix both swing Jaw Stocks Fig. 1, F F to form a Butt
Hinge G on one Shaft Fig 2, C to hang in the centre of top of Frame A, at the
bottom of the Jaw Stocks Fig. 1, F F there is a series of Toggle Groves H H.
I employ a long Crank Lever I the Fulcrum in the centre at the bottom of the
Frame A the Crank end of Lever J at right angle the other end of the Lever I
horizontal. I employ one ordinary Toggle K on each side of the Crank end of the
Lever J at right angle, The Toggles K K at an angle in a series of Groves H H
the other end of Toggles K K at the bottom of the Butt Jaw Stocks F F in a
series of Groves H H by changing the Toggles K K from one Grove H to the
others it regulates the motion of the Machine, I attach a spiral spring L to each
Butt Jaw Stock F for the draw-back Motion, I couple a connecting Rod M at the
horizontal end of the Lever I which terminates with end of the Frame A, the other
end I couple with a Crank or Excentric Fig. 2, N with the arrangement of the
Butt Jaw Stocks Fig. 1, F F Toggles K K and long Lever I the Crank end J
moving right and left it must consequently take less power, by my arrangement
of the Butt Jaw Stocks F F they bring the Mouths of the Machine Fig. 2, 00 80
close together which by preference may be fed on one side of the Machine and
deliver the double quantity of material on the other Fig. 3, P. in the end of the
Frame A and Butt Jaw Stocks F FI insert loose Jaw faces Q in halves, in Butt
Jaw Stocks F F and Crank Lever J I insert renewable Toggle Groves H H or in
the ordinary way with a series of Groves H H.
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,
(1.) The combined Machine as a Stone Breaker or Ore Crusher, as hereinbefore
described.
(2.) By my arrangement of the Frame and Butt Jaw Stocks to form an hinge,
the Spiral Spring to each Butt Jaw Stock for the Draw-back Motion, as herein.
before described.
(3.) By my arrangement of the Long Crank Lever with a series of Groves, and
Butt Jaw Stocks with a series of Groves the Mouths are brought closer together as
herein before described.
