Improvements in Stone Breaking and Crushing Machines.
I, SAMUEL MASON of Brandon Street Leicester in the County of Leicester
Engineer do hereby declare the nature of this invention to be as follows:-
My invention consists of improvements of parts used in stone breaking &
crushing machines as hereinafter described. The said invention is a toggle boss
or bearing of any suitable size & material on the top of which 1 put a projection
or nose piece.
In or near the centre of the said toggle boss or bearing I put an eccentric or
cam shaft which when revolved gives motion to a lever, the said lever imparting
a backward & forward movement to a swinging jaw which is used for breaking or
crushing stones or any other substances. The said toggle boss or bearing I make
in halves which are fastened together by means of bolts or screws, in the bottom
half of the said toggle boss or bearing I put a moveable & adjustable bearing
which is regulated by means of one or more wedges or screws so that when the
bearings & eccentric or cam shaft wears the said moveable & adjustable bearing
is kept up to the said eccentric or cam shaft by means of the said wedges or screws
& so gives longer wear, saves time & prevents friction.
Dated this 17th day of December 1896.
