Improvements in Toggle Plates for Stone Breaking and Ore
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 plates made in the following manner of cast iron or any
suitable material for the purpose of connecting & adjusting the jaws of stone
breaking & ore crushing machines.
I first make a plate of any suitable length or width which I will call No. 1
through which I put one or more bolts & on the top of this plate I put another
similar plate of any suitable length or width which I will call No. 2, in this No. 2
plate I put one or more holes through which the bolts in No. 1 plate are inserted
& screwed up, by putting the holes in No. 2 plate it is permitted to slide upon No. 1
plate & so lengthened or shortened as required for the purpose of adjusting the
jaws of the said stone breaking & ore crushing machines. When desired length is
attained the said bolts are screwed up.
I also make a plate in one piece which I will call No. 3. of any suitable material,
that is one plate cast upon the other the distance of " or more which forms a neck,
in this way the plate can be made of various strengths to suit the stone or ore the
machine has to break, this plate is not adjustable so to adjust the jaws another plate
of a suitable length is inserted.
I also make an adjustable plate similar to No. 3 which I will call No. 4 in the
following manner.-I put one or more holes near the end of No. 4 plate then I
make another similar plate to No. 2, which I will call No. 5 through which near
the end I put one or more bolts the said bolts are inserted into the holes of No. 4
plate which will then slide upon No. 5 plate & so lengthened or shortened as
required. My object for inventing these plates is to prevent serious breakages in
stone breaking or ore crushing machines, so that if iron or any foreign matter gets
between the jaws of the said machines these plates will instantly give way & do no
injury to machines.

COMPLETE SPECIFICATION.
Improvements in Toggle Plates for Stone Breaking and Ore
Crushing Machines.
I SAMUEL MASON of Brandon Street 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 :-
This invention relates to toggle plates for stone breaking & ore crushing machines
made in the following manner of cast iron or any suitable material for the purpose
of connecting and adjusting the jaws of the said stone breaking & ore crushing
machines.
Firstly I make a plate of any suitable length and width Fig. 1 in drawings,
through this said plate I put one or more bolts, and on the top of plate Fig. 1 I put

page_text: another similar plate of any suitable length and width, Fig. 2 in drawing, in which
I put one or more boles, through these holes the said bolts in No. 1 plate are
inserted & screwed up. My object in putting holes in No. 2 plate is so that
it may be permitted to slide upon No. 1 plate & so lengthened or shortened as
required for the purpose of adjusting the jaws of the said stone breaking & ore
crushing machines, when desired length is attained the said bolts in No. 1 plate are
screwed up.
Secondly I make a plate of cast iron or any suitable material Fig. 3 in drawings,
it will be seen one plate is cast upon the other any suitable distance to form a
neck, in this way I make the said plates of various strengths to suit the stone or
ore the machine has to break, this plate is not made adjustable so to adjust the
jaws another plate of a suitable length is inserted.
Thirdly, I make a plate similar in construction to No. 1 & 2 & which is also
adjustable see Fig. 4 & 5 in drawing. No. 5 plate is made to slide upon No. 4
plate when the jaws of the machines are required to be adjusted. My object for
inventing these plates is to prevent serious breakages in stone breaking & ore
crushing machines that is if iron or any foreign matter gets between the jaws of
the said machines, these plates will instantly give way & do no injury to machine.
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,
First. The construction & use of toggle plates for the purpose hereinbefore
described & illustrated by Fig. 1 and 2 in drawings.
Second. The construction & use of toggle plates as illustrated by Fig. 3. in
drawings.
Third. The construction & use of toggle plates as illustrated by Fig. 4 & 5
in drawings.
