Improvements in and relating to Mixing and Distributing Appliances
for Fibrous or Granular Materials.
I, STEPHEN HULME, of 124, Swanston Street, Dalmarnock, in the County of
the City of Glasgow, Engineer, do hereby declare the nature of my invention
to be as follows:-
This invention has reference to and comprises improvements in and relating to
mixing and distributing appliances and consists of a centrifugal mixer and distri-
butor so driven by differential speed gear that the material which may be fibrous
material such as cotton or granular material such as wheat or any like material
or materials to be mixed and distributed, or simply distributed, can be delivered
at a varying distance from the centre by the varying speed of the distributor and
so deposit and build it up in an even manner.
In carrying this invention into practice the centrifugal distributor is mounted
on a vertical shaft driven by belt or other suitable gearing by any arrangement
of differential speed gearing which may be a pair of reversed conical pulleys
or rollers, one receiving motion from any prime mover and driving by means
of a belt the other which communicates motion to the distributor. The belt
may be automatically shifted along the pulleys by means of a forked lever
conveniently fulcrumed the bent end of which is provided with a roller and
acted on by a cam which may be of a heart shape or any other suitable form
and be driven by worm wheel gearing from the prime mover and a spring may
be used to give a reaction motion. The centrifugal distributor consists of a
curved appliance which may be of an approximately volute form somewhat
similar to the blade of a screw propeller and is mounted on the vertical shaft
near its one end, the distributor is also hollowed or curved on its front to
receive the material dropped upon it and the curve of this hollow varies from
one end to the other.
The material to be mixed and distributed is fed to the distributor from a
hopper above to which it is fed in any ordinary manner.

Improvements in and relating to Mixing and Distributing Appliances
for Fibrous or Granular Materials.
I, STEPHEN HULME, of 184, Swanston Street, Dalmarnock, in the County of
the City of Glasgow, Engineer, do hereby declare the nature of my invention
and in what manner the same is to be performed to be particularly described and

ascertained in and by the following statement in writing reference being made
to the accompanying sheet of drawings.
This invention has reference to and comprises improvements in and relating
to mixing and distributing appliances, and consists mainly of a centrifugal mixer
and distributer so driven by differential speed gear that the material, which may
be fibrous material, such as cotton, or granular material such as wheat or any
like material or materials, to be mixed and distributed, or simply distributed, can
be delivered at a varying distance from the centre by the varying speed of the
distributer and so be deposited and built up in an even manner.
And in order that my said invention may be properly understood I have here-
unto appended a sheet of explanatory drawings in which Figure 1 is an elevation
partly in section of the complete appliance with the cover removed from the casing
containing the differential motion gearing; Figure 2 an elevation of the
other side of the centrifugal distributer and Figure 2ª a section of same on the
line 1-1 while Figure 3 is an end view of the casing containing the conical belt
rollers and differential motion gearing:
In carrying this invention into practice the centrifugal distributer A is mounted
on a vertical shaft B driven by the belt C or by other suitable gearing by an
arrangement of differential speed gearing which is preferably a pair of reversed
conical pulleys or rollers D D1, the one D receiving motion from any prime mover
by the belt pulley D² and driving the other 11 by means of a belt D³ which com-
municates motion to the distributing device by means of the wheel gear-
ing d d d d³ and belt pulley d, which conveys motion by the belt C to the
pulley B¹, the belt C being carried to a pair of guide pulleys C placed to one
side..
The belt D³ may be automatically shifted along the pulleys D D¹, by means of
a forked lever, conveniently fulcrumed, the bent end of which is provided with a
roller and acted on by a cam which may be of a heart shape or any other suitable
form and be driven by worm wheel gearing from the prime mover, and a spring
may be used to give a reaction motion.
Preferably however the duplex arrangement of levers E E as shown is employed
these levers being fulcrumed on stud pins Ea within the casing F, and caused to
work in unison by means of the toothed quadrants E3 on their adjacent ends, the
other ends being provided with pins E4 to engage with the belt D³ to shift it.
The lever E is oscillated by the movement of the lever G fulcrumed on the
casing F and engaging with the end of the lever E by a pin G₁ on its end passing
through an opening in the casing. This lever G has an antifriction pulley G2 on
its bent over end which is acted on by the heart shaped cam H driven at a slow speed
by means of a worm screw I on the same spindle which carries the conical roller D,
a weighted lever G³ being employed to keep the roller G2 always in contact with
the heart shaped cam H. The cam H is rotated by the worm screw I turning
the worm wheel I¹ which is mounted loose on the spindle 12 and this wheel I¹
turns a toothed wheel keyed on the spindle I2 at the back of the fixed wheel I³
the pinion at same time rolling around the fixed wheel and this fixed wheel having
one tooth less than the wheel keyed on spindle, the latter is caused to rotate at a
slow speed. The spindle I2 is carried in the hollow trunnion of the fixed wheel I³
as a bearing, and the trunnion is secured in the bracket 15 by pinching screws.
The centrifugal distributer A. consists of a curved appliance which may be of
an approximately volute form somewhat similar to an arm of a screw propeller but
is preferably of the scoop form shown in the drawings Figures 1, 2 and 2* and
fitted with counterweight A' and is mounted near its larger end on the vertical
shaft B. The distributer is also hollowed or curved on its front to receive the
material dropped upon it and the curve of the hollow varies from one end to the
other.
The material to be mixed and distributed is fed down on to the distributer from
any hopper or like device above, to which it is fed in any ordinary manner.

page_text: Having now particularly described and ascertained the nature of my said in-
vention and in what manner, the same is to be performed I declare that what I
claim is:-
First. Mixing and distributing appliances constructed and arranged all sub-
stantially as herein described and illustrated by the accompanying drawings.
Second. The combination of the mixing and distributing device A and the
differential speed gearing all substantially as herein described and illustrated by
the accompanying drawings.
!
Third. In appliances for mixing and distributing material the differential speed
gearing constructed and arranged all substantially as herein described and illus-
trated by Figures 1 and 3 of the accompanying drawings.
Fourth. In appliances for mixing and distributing material the construction
and use of the distributing device A all substantially as herein described and
illustrated by Figures 1, 2 and 2 of the accompanying drawings.
