We THOMAS MILLS MASON 15 Shaftesbury Avenue Leicester, JOHN HENRY
MASON 13 Shaftesbury Avenue Leicester & ARTHUR MASON The Elms" Lough-
borough Road Leicester in the County of Leicester Engineers trading as Mason
Brothers Engineers Brandon Street Leicester do hereby declare the nature of
this invention to be as follows:-
:-
The object of our invention is to provide a machine which shall be applicable
for both breaking all kinds of hard stones for Ballast & Macadam purposes also
for crushing & pulverizing other materials for concrete & grinding purposes.
We make a frame of cast iron or any suitable material in one piece or four
pieces bolted together, in the front of the frame we put a fixed Jaw & opposite
to the fixed Jaw we suspend in suitable bearings a swinging Jaw, through the
top of this swinging Jaw we put an eccentric shaft which when revolved by
means of a pulley gives a crushing & Granulating motion to the said swinging
Jaw, at the back of the said swinging Jaw we put three or more Grooves for
the purpose of giving different motions to suit the different kinds of material
under operation. We also put two other suitable bearings in the said frame at a
suitable distance & opposite the said grooves in the swinging Jaw, in these
bearings we put another Eccentric shaft & hetween this eccentric shaft & swing-
ing Jaw we put a Boss & at the front end of this Boss we put an adjustable plato
in which we put one or more slot holes of a suitable length to allow the plate to
be moved forward or backward for adjusting the said swinging jaw, the nose of
this plate is put into one or the other of the said grooves in the swinging Jaw
to suit the nature of the stone to be broken & when the bottom eccentric shaft
is revolved it moves the swinging Jaw forwards & backwards for breaking all
kinds of hard stones, the swinging Jaw is adjustable by means of the said plate
for breaking the 'material down to the size required, thus by our Invention any
kind of stone or ore can be operated upon for Macadam, Ballast, Concrete &
Grinding purposes by simply changing the driving wheels from one Eccentric
shaft to the other.

page_text: 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:-
Our Invention is to provide a machine which shall be suitable for both breaking

of cast iron or other suitable material in one piece or four pieces bolted together,
in front of the frame we put a fixed Jaw No. 1 in accompanying drawings &
opposite we suspend in suitable bearings a swinging Jaw No. 2, through the top of
this swinging Jaw we put an eccentric shaft No. 3 which when revolved by the
driving wheels O gives a up, down, backward & forward movement
swinging Jaw No. 2, & so pulverizes the material under operation.
to the
At the back of the said Swinging Jaw we put three or more Grooves which by
putting the nose of the adjustable Toggle plate No. 6 into one or the other of
these grooves, gives more or less movement to the said swinging Jaw No. 2 to
suit the material under operation.
We also put two other suitable bearings in the said frame at a suitable
distance and opposite the grooves in the said Swinging Jaw No. 2, and in these
bearings we put another eccentric shaft No. 4 and on this said shaft we put a
Boss or Bearing No. 5, and at the front end of this boss or bearing we put a
Toggle plate No. 6, and in this plate we put one or more slot holes of a suitable
length so when the bolt is unscrewed the said Toggle.plate No. 6, can be moved
backward or forward for the purpose of adjusting the said Swinging Jaw No. 2,
that is, so the material under operation can be broken larger or smaller as
required.
When the bottom Eccentric shaft No. 4 is revolved by means of the driving
wheels O, it moves the swinging Jaw No. 2 simply forward & backward which
is a suitable movement for breaking all kinds of hard stones for macadam or
ballast. So by this invention when hard stones are required to be broken the
driving wheels are put on the Eccentric shaft No. 4, & worked as Fig. and when
the material is required to be crushed or pulverized for concrete and grinding
purposes the driving wheels are put on the top Eccentric shaft No. 3, & worked
as Fig. 1.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The arrangement & combination of parts constituting the apparatus for
breaking also for granulating ores or other hard substances by simply changing
the driving wheels from one eccentric shaft to the ether as hereinbefore described
and illustrated by Figures 1 and 2 in accompanying drawings.
2. The adjustment of the swinging Jaw by means of a sliding Toggle plate
No. 6, as hereinbefore described and shown in accompanying drawings.
