PROVISIONAL SPECIFICATION.
A Feeding Machine, chiefly designed for Feeding Ore to Crushing
Mills, Stamps, and the like.
I, WILLIAM JOHN GILBERT, of Lynton Villa, Tehidy Road, Camborne, in the
County of Cornwall, Mining Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a machine or apparatus chiefly designed for feeding ore
to crushing mills, stamps and the like but also applicable for feeding other
materials to machines in which they are treated.
My apparatus comprises a framework preferably of wood and mounted upon
small wheels or rollers and preferably running upon rails so that the apparatus can
be moved from place to place. In this frame I mount a receptacle for the material
to be fed, the bottom of the said receptacle being inclined to cause the said
material to gravitate towards a discharge opening. In conjunction with this
opening is a sliding-door having fixed upon it a rack with which engages a
pinion mounted upon a shaft carried in suitable bearings upon the frame, the
said shaft having a hand-wheel by means of which it may be operated to raise
or lower the door for regulating the size of the discharge opening. Below or
in proximity to the discharge opening I fix a roller (which may be either plain
or fluted or otherwise roughened) in such a manner that as the said roller
rotates it will draw the material out of the said receptacle between itself and
the lower edge of the sliding door, and below this roller is a plate or shoot
for directing the material to be discharged to the point at which it is to be
delivered. This roller is preferably rotated by the following means, that is to
say, upon the shaft carrying the same is fixed a wheel with which engages a
gripper or clutch pivoted to one end of a rod, the other end of which is connected
with a lever adapted to be acted upon by a knocker in such a manner as to
move the rod carrying the gripper or clutch to rotate the drum and then
release it to allow the said gripper or clutch to move back. In connection with
the said gripper or clutch is a screw for regulating the movement of the said
clutch.

COMPLETE SPECIFICATION.
A Feeding Machine, chiefly designed for Feeding Ore to Crushing
Mills, Stamps, and the like.
I, WILLIAM JOHN GILBERT, of Lynton Villa, Tehidy Road, Camborne, in the
County of Cornwall, Mining 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 a machine or apparatus chiefly designed for feeding ore
to crushing mills, stamps and the like but also applicable for feeding other
materials to machines in which they are treated.
In the accompanying drawing,-
Figures 1 and 2 are elevations at right angles to each other of my improved
feeding machine; and,
Figures 3 and 4 are views illustrating a detail of my invention.

page_text: My apparatus comprises a framework a of wood or other suitable material and
preferably mounted upon small wheels or rollers b, band running upon rails c, c
so that the apparatus can be moved from place to place. In the frame a
I mount a receptacle or hopper d for the material to be fed, the bottom of the
said receptacle being inclined to cause the said material to gravitate towards a
discharge opening e. In conjunction with this opening is a sliding-door f having
fixed upon it a rack g with which engages a pinion h mounted upon a shaft i
carried in suitable bearings upon the frame, the said shaft having a hand-
wheel by means of which it may be operated to raise or lower the door for
regulating the size of the discharge opening e. Below or in proximity to the
discharge opening I fix a roller k (which may be either plain or fluted or
otherwise roughened) in such a manner that as the said roller rotates it will
draw the material out of the said receptacle between itself and the lower edge
of the sliding door, and below this roller is a plate or shoot for directing the
material to be discharged to the point at which it is to be delivered. The
roller is advantageously. rotated by the following means, that is to say, upon
the shaft m carrying the said roller is fixed a wheel n having flanges o, o with
which engages a gripper or clutch p movably connected to one end of a rod q,
the other end of which is connected with a lever r adapted to be acted upon
either directly or through the medium of a rod & by a knocker such as t so as
to lift the rod q carrying the gripper or clutch to rotate the wheel and the
drum and then release the said rod to allow the said gripper or clutch to move
back under the action of a weight such as q' or by its own gravity.
In Figures 3 and 4 the clutch p is represented as being composed of two
flanged plates u, u fixed to a block upon the lower end of the rod g, the said
flanges being so arranged that when the clutch is moved up, for instance to the
position indicated by the dotted lines, the flanges o, o of the wheel n will be
gripped between the flanges of the plates u, u and the block in a well known
manner, thereby rotating the said wheel n in the direction of the arrow Figure 3.
As the rod g again drops the flanges of the clutch will slip along the flanges
of the wheel.

In connection with the said gripper or clutch is arranged a screw w for regulating
the downward movement of the said clutch.
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. In a machine for feeding ore to crushing mills, stamps and the like and for
similar purposes, the combination of a hopper on a movable frame, an adjustable
door adapted to regulate the size of the opening in the front of the said hopper
and a roller for causing the flow of material from the hopper, substantially as
described.
2. In a machine of the kind referred to in the preceding claiming clause the
combination with the feeding-roller of a gripper or clutch such as p adapted to be
operated through the medium of suitable rods and levers to impart motion to the
said roller, substantially as described.
3. The improved machine for feeding ore to crushing mills, stamps and the like
and for similar purposes, constructed and arranged substantially in the manner
hereinbefore described and illustrated in the accompanying drawing.
