Improvements in and Apparatus for Feeding Elevators and
Conveying Machinery.
MAURICE GRAHAM, Cawder House, Poplar Avenue, Edgbaston, Birmingham
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and apparatus for feeding elevators
and conveying machinery.
My improvement consists in attaching to the receiving hopper, boot or feeding
end of the elevators or conveyors-either directly or indirectly by means of fun-
nels or spouts--a chamber or measuring box which has a circular drum revolving
upon an axle or pivot inside. This drum is preferably in the form of a revolving
cylinder but may be of any shape to suit the detail. This revolving chamber may
be divided into one or more compartments or divisions either longitudinally or
transversally.
The drum being in a case which has an opening at the top for receiving the
material and also an opening at the bottom for allowing the material to fall out
of the chamber.
These openings at the top and bottom of the case, chamber, or box are provided
with slides or valves.
The apparatus works as follows:-
When the material falls through the top opening it falls then into one of the
compartments or divisions provided in the revolving chamber or drum.
The drum is then turned round on its axle or pivots and another compartment
is ready to be filled with material. As the first compartment reaches the bottom
door, the material falls out and this empty compartment travels in the revolution,
to the top again to receive another supply of material, and again emptying itself
at the bottom door or opening.
The revolving drum when working may have only one compartment or division,
or as many as desirable, and these receive a charge or supply of material when
passing the top opening and deposit it when passing the bottom opening. The
compartments have adjustable slides and doors and frames for varying the quantity
of material for each compartment.
The speed of the drum revolving also regulates. the supply.
It will be understood the foregoing is given by way of illustration and that
the shapes, materials, and parts or combination of parts of the apparatus may be
varied in many ways within the scope of my invention.

I, MAURICE GRAHAM, of Cawder House, Poplar Avenue, Edgbaston, Birmingham,
in the County of Warwickshire, 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 improvements in and apparatus for feeding elevators
and conveying machinery.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a vertical section of the measuring box and hopper.
Fig. 2, is a side elevation of the measuring box.
My improvement consists in attaching to the receiving hopper boot a or feeding
end of the elevators or conveyors, either directly or indirectly by means of funnels
or spouts, a chamber measuring box which has a circular drum e revolving upon
an axle d or pivot inside. This drum is preferably in the form of a revolving
cylinder but may be of any shape to suit the detail. This revolving chamber or
drum c may be divided into one or more compartments or divisions e either longi-
tudinally, or transversally. The drum being in a case which has an opening f
at the top for receiving the material and also an opening at the bottom for
allowing the material to fall out of the chamber.
These openings at the top and bottom of the case, chamber or box are provided
with slides or valves.
The apparatus works as follows:-
When the material falls through the top opening f, it falls then into one of the
compartments or divisions e provided in the revolving chamber or drum c.
The drum is then turned round on its axle or pivots, and another compartment
is ready to be filled with material.
As the first compartment reaches the bottom door, the material falls out and
this empty compartment travels in the revolution to the top again to receive
another supply of material, and again emptying itself at the bottom door or
opening.
The revolving drum when working may have only one compartment or division,
or as many as desirable, and these receive a charge or supply of material when
passing the top opening, and deposit it when passing the bottom opening. The
compartments have adjustable slides and doors and frames for varying the quan-
tity of material for each compartment.
The speed of the drum revolving also regulates the supply. It will be under-
stood the foregoing is given by way of illustration and that the shapes materials
and parts or combination of parts of the apparatus may be varied in many ways
within the scope of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
:―
1. In an apparatus for feeding elevators, the combination and arrangement of

page_text: the various parts of mechanism as above described in this specification for the
purpose specified.
2. In an apparatus for feeding elevators, the combination of the various parts,
substantially as herein described and according to the accompanying drawing.
Dated this 25th day of October 1898.
