I, SAMUEL MASON of Belgrave Road Leicester in the county of Leicester Engineer
do hereby declare the nature of this invention to be as follows:-
I make a frame similar to that known as the Blakes, at the back of which I place a
crank or eccentric shaft which gives an oscillating motion to a vertical lever which is
connected to the crank or eccentric shaft at the upper end by a link. In or near the
centre of the said vertical lever I place a shaft which takes its bearing in the frame of
machine. I also place at the bottom of the said vertical lever 3 or more grooves made
of malleable iron or steel in which works my patent adjustable toggle. This is made
in two parts so that one slides on the other & are fastened together by bolts which
gives movement to the swing Jaw suspended by a shaft at the top of the frame. In
the said swing Jaw I also put 3 or more grooves so that I can give different lengths
of stroke or movement by means of the said, adjustable toggle-At the front of
machine 1 place a fixed Jaw so when the said swing Jaw is actuated by the vertical
lever it crushes or breaks the stone-When the ordinary toggle is used 1 adjust the
bottom of the said vertical lever by a screw or wedge piece in the bearings of the
frame This invention dispenses with toggle or wedge blocks also one toggle plate &
takes very little power to work it.

I SAMUEL MASON of Belgrave Road Leicester in the county of Leicester Engineer
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
I make a frame similar to that known as the Blake at the back of which I place
two arms for a crank or eccentric shaft to work upon see No. 4 which gives an
oscillating motion to a vertical lever see No. 5 which is connected to the crank or
eccentric shaft at the upper end by a link see No. 6, in or near the centre at the lower
end of the said vertical lever I place a shaft which takes its bearing in the frame of
the machine. I also place in the bottom of the said vertical lever three or more
grooves made of malleable iron or steel see No. 7 in which works my adjustable
toggle see No. 8 Fig. 2 this is made in two parts so that one slides upon the other &
is fastened together by bolts this gives movement to the swing jaw suspended by a
shaft at the top of the frame. In the said swing jaw I also put three or more grooves
so that I can give different lengths of stroke or movement by means of the said
adjustable toggle at the front of machine I place a fixed jaw so when the said swing
jaw is actuated by the vertical lever it crushes or breaks the stone, when the ordinary
toggle is used I adjust the bottom of the said vertical lever by a screw or wedge piece
in the bearings of the frame-This invention dispenses with the toggle & wedge blocks
also one toggle plate although the machine can be worked with a wedge block also
toggle block see Fig. 3 Nos. 9 & 10.
Having now particularly described the nature of my said invention & in what
manner the same is to be performed I declare that what I claim is-
1. The vertical lever as shown in Fig. 1, 2, 3 & 4. No. 5.
