PROVISIONAL SPECIFICATION.
Improvements in Stone-breaking and Crushing Machines."
I SAMUEL MASON of Brandon Street, Belgrave Road Leicester in the County
of Leicester Engineer do hereby declare the nature of this invention to be as
follows:-
My invention consists of improvements in a class of machine known as a breaker
or crusher for breaking up stones & other substances which is operated upon by
means of a moveable jaw suspended upon an axis-the said moveable jaw is vibrated
in proximity to a fixed jaw which crushes the stones & other substances fed
between them. The said vibration to the moveable jaw is effected by means of
a lever which takes a bearing upon a shaft at one end, the other end taking its
bearing upon a toggle boss which is oscillated by means of an eccentric or cam
shaft. An adjustable toggle plate is placed between the back of the said moveable
jaw & front of the said lever which is lifted & lowered any suitable distance by
means of the said toggle boss to give the required vibration to the said moveable
jaw. The adjustmeut of the jaws is effected by means of the said adjustable toggle
plate, & the return motion of the said moveable jaw is ensured by a rod or spring
in the ordinary way.

COMPLETE SPECIFICATION.
Improvements in Stone-breaking and Crushing Machines.
J SAMUEL MASON of Brandon Street 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 :-
My invention consists of improvements in a class of machine known as a breaker
or crusher for breaking up stones & other substances which is operated upon by
means of a moveable jaw No. 1 in the accompanying drawings suspended upon an
axis No. 13.
The said moveable jaw No. 1 is vibrated in proximity to a fixed jaw No. 3
which crushes the stones & other substances fed between them. The said vibration
to the moveable jaw No. 1 is effected by means of a lever No. 5 which takes a
bearing upon a shaft at one end No. 18 the other end taking its bearing upon a
toggle boss No. 15 which is oscillated by means of an eccentric or cam shaft No. 14.
An adjustable toggle plate No. 4 with sliding nose piece No. 6 is placed between
the back of the said moveable jaw No. 1 & front of the said lever No. 5 which is
lifted & lowered any suitable distance by means of the said toggle boss No. 15 to
give the required vibration to the said moveable jaw.
The adjustment of the moveable jaw No. 1 is effected by means of inserting or
taking out the liners No. 17 of different thicknesses between the said adjustable
toggle plate No. 4 & sliding nose piece No. 6. The return motion of the said
moveable jaw No. 1 is ensured by a rod & spring No. 11 in the ordinary way.
Having now particularly described & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is―
1. An apparatus for breaking or crushing stones or other substances, the

page_text: combination with the jaws between which the stones or other substances are
crushed, of a lever lifted & lowered by means of a toggle boss acted upon by an
eccentric or cam shaft, & operating the moveable jaw through the intervention of
an adjustable toggle plate as hereinbefore. described & illustrated in the accom-
panying drawings.
2. The arrangement & combination of parts for the purpose of breaking or
crushing stones or other substances as herein before described & illustrated in the
accompanying drawings.
3. I would observe I do not claim the several parts separate & apart from each
other, but what I consider novel therefore I claim the coinbination & arrangenient
of parts in the manner for the purpose hereinbefore set forth & described &
illustrated in the accompanying drawings or any mere modifications thereof.:
Dated this 9th day of September 1892.
