PROVISIONAL SPECIFICATION.
Improvements in Stone Breaking and Crushing Machinery.
I, GEORGE LOWRY, of Tiffan, Ohio, United States of America, Mechanical
Engineer, do hereby declare the nature of this invention, to be as follows:-
My invention has reference to certain improvements in stone breaking and
crushing machinery.
According to my improvements a vertical shaft is fitted with, and fulcrumed
between two tapering heads, one beneath the other, so as to obtain a double action
rock breaker and ore crusher, the said vertical shaft has motion imparted to it by
belt or rope driving a pulley keyed to an eccentric which forms the bearing for the
lower end of the said shaft. The said belt or rope drives direct on to the said pulley
and without the intervention of a countershaft and outside driving pulley on the
countershaft. The said eccentric is provided with runners or wheels so as to
reduce friction upon the foundation plate of the machine, and to give an increased
speed of the machine.
The rotation of the said spindle causes the said heads to move round also, and
break and crush the material between themselves and tapering jaws or projecting
ledges upon the case of the machine. The top jaws are fixed and these along with
the top head are used for rough breaking, the lower jaws are adjustable by means
of screws, and these along with the lower head are used for crushing or breaking
the material to the required gauge, by adjusting the lower jaws or liner the fineness
of the crushing action can be regulated.
Beneath the lower jaws and head the case of the machine is made with a
projecting rim or ledge on which is fixed a casting forming the top part of the
shoot for discharging the broken or crushed material, a lower part or spout being
attached thereto for discharging outside the machine.
For oiling the ball bearing in the vertical shaft I provide a hole leading from the
top vertical shaft down the centre and out at the side into a recess provided in the
top head, down a groove on to the outside of the ball bearing.

page_text: According to my improvements a vertical shaft A is fitted with, and fulcrumed
at B (by a ball bearing R and head or support U) between, two tapering
heads C and D, one beneath the other, so as to obtain a double action rock breaker
and ore crusher.
. The said vertical shaft A has motion imparted to it by belt D¹ or rope driving
a pulley E keyed to an eccentric F which forms a bearing into which the lower
end of the said shaft A passes. The said belt D' or rope drives direct on to the
said pulley E through openings A' in the frame of the machine, and without the
intervention of a countershaft and outside driving pulley on the countershaft.
The said eccentric F is provided with runners or wheels G so as to reduce friction
upon the bearing H in the foundation plate H¹ of the machine, and to give an
increased speed of the machine. The motion of the said shaft or spindle A causes
the said heads C and D to gyrate or move to and fro, and break and crush the
material between themselves and tapering jaws or projecting ledges J and L
fixed in or upon the case M of the machine.
The top jaw J is fixed, and this along with the top head C is used for rough
-breaking. The lower jaw L is adjustable by means of screws N, through the
openings N', and this along with the lower head D is used for crushing or breaking
the material to the required gauge, by adjusting the lower jaw or liner L, the fineness
of the crushing action can be regulated.
Beneath the lower jaw L and head D the case M of the machine is made with a
projecting rim or ledge O on which is fixed a casting P forming the top part or
hopper of the shoot for discharging the broken or crushed material, a lower part
or spout P being attached. thereto for discharging outside the machine.
For oiling the ball bearing R on the vertical shaft A I provide a hole S leading
from the top of the vertical shaft. A down the centre and out at the sides into a
recess T provided in the head or support U down a groove on to the outside of the
ball bearing R.
My said invention is applicable for breaking and crushing stone, ores, and other
mineral substances.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A machine of the kind referred to having a vertical shaft A fulcrumed at B
between tapering_heads C and D, the driving or motion of the said shaft causing
the heads C and D to gyrate or move to and fro, and break and crush the material
between them and tapering jaws or projecting ledges J and L, such as shown and
described.
2. In a machine of the kind referred to, the combination of an eccentric F
provided with runners or wheels G and a driving pulley E secured to the said
eccentric, substantially as and for the purposes such as shown and described.
3. In a machine.of the kind referred to, the combination with the lower jaw L
of means to adjust such lower jaw or liner relatively to the lower head D so as to
regulate the gauge, such as shown and described.
4. In a machine of the kind referred to, the construction and arrangement of
hopper and shoot, substantially as and for the purposes shown and described.
5. The improved machine or apparatus as and for the purposes shown and
dasasihad
