page_text: Improvements in Mixing Machines.
I, JAMES FRAZIER, of Hamilton, Ohio, U.S.A., Inventor, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to provide means for mixing substances, in which
the amount of mixing can be readily regulated, and further, to provide means for
ensuring a continuous and even feed of the substances.
The machine comprises a suitable hopper having parallel sides, by preference,
and a vertically arranged shaft journalled therein and adapted to be rotated by
suitable gearing.
A disc is mounted on the shaft, beneath the hopper, and supports a cone having
projections on its surface, and which tends to throw the substance being mixed
towards the periphery of the opening in the lower part of the hopper. The size of
this opening is capable of being regulated by means of a sleeve fitted on the lower
part of the hopper and capable of being raised from or lowered towards the top
surface of the disc, by screws and handwheels or the like, so as to permit the sub-
stance being mixed to be emitted more or less rapidly according to the amount of
mixing required.
•
A suitable receptacle is arranged beneath to disc to catch the mixed substance,
and from which it may be conveyed through openings as required.
Agitators, consisting of arms, are secured to the shaft to ensure a continuous
flow of the substance to the hopper and to assist in the mixing.

I, JAMES FRAZIER, of Hamilton, Ohio, U.S.A., Inventor, 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 machines for mixing various substances, such as bran,
meal, middlings, sweepings etc.
The object of the invention is to provide a machine of the kind in which the
amount of mixing can be readily regulated; a continuous and even feed of the
D

page_text: substance to be mixed ensured; which will not choke; which can be driven from
either side; which can be made to discharge at various convenient parts; which
can be regulated to discharge any desired quantity in a given time; which will
discharge all that enters the hopper; which requires little power and space;
which works with a slow motion, though rapid in its operation; which will not spill
or waste any of the ingredients to accumulate beneath the machine; which, being
built of metal, its parts will not warp and get out of order; and which is light,
strong, and durable.
Reference being had to the drawings hereunto annexed:-Figure 1 is a vertical
section of a mixing machine constructed in accordance with my invention, and
Figs. 2 and 3 are detail views of two of its parts.
The machine comprises a framework 1 consisting of four standards 2 supporting
an annular band 3.
A hopper 4 is supported by screws 5 within the band 3, and extends above and
below the same as shewn.
Beneath the hopper is an annular pan or receptacle 6 secured to the standards 2
by screws 7, and having any desired number of discharge openings 8, closed by
plates 9, secured by screws 10, or other suitable means.
A shaft 11 is journalled in a bearing 12, supported by arms 13 extending across
the hopper and also in a step 14 depending from the underside of the pan 6. This
shaft is capable of being rotated by bevel wheels 15 and 16; the latter being
mounted on a shaft 17, journalled in the standards 2, and carrying a pulley 18 at
either end, and a collar 19 which can be adjusted by a set-screw 20, to enable the
longer end of the shaft to be adjusted in such manner as to project to either side to
carry the pulley 18; the set-screw 21 in the bevel-wheel being also loosened to
enable the shaft to be slid through it or for the wheel to be adjusted on the
opposite side of the bevel-wheel 15, to reverse the direction of the shaft 11 if
desired.
The shaft 11 carries any number of agitators 22, to ensure a proper feed
of ingredients in the hopper, and a conical shaped agitator 23 having wings 24.
This agitator is supported by and fits around a concentric ridge on a disc 25,
mounted upon the shaft 11 and having scrapers 26, on its underside, resting in
the pan 6.
A sleeve 27 is slidingly fitted on the lower part of the hopper and has a flange or
lugs 28, in which screws 29 are threaded; the screws being rotatably supported by
brackets 30 on the framework, in such manner that endwise movement of the
screws is prevented.
In operation, the substance to be mixed is placed in the hopper 4, is stirred by
the agitators 22, and falls onto the agitator 23; the wings 24 on which, tend to
force it in a downward direction onto the disc 25 whence it falls into the pan 6,
and is carried by the scrapers 26 over the discharge apertures 8, from any desired
one of which it is discharged, when one or more of the plates 9 are removed.
The amount of the mixing is regulated by the rapidity of the discharge, which
is governed by raising the sleeve 27 away from the disc 25 by means of the
screws 29, or lowering it towards the same."
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:-
:-
A mixing machine comprising a framework supporting a suitable hopper; a
pan supported beneath the hopper, and having discharge openings capable of being
opened and closed as required; a shaft journalled centrally within the hopper and
pan agitators carried by the upper part of the shaft; a conical shaped agitator by
the lower part thereof; a disc carried by the shaft beneath the hopper, and having
a concentric ridge upon its upper surface, and scrapers upon its lower surface; a
sleeve slidably fitted to the lower end of the hopper; means such as screws for
adjusting the sleeve upon the hopper vertically; a shaft adjustably journalled in

page_text: the framework to carry a pulley at either end; and means, such as gearing, adjust-
ably mounted on the shaft for imparting rotary motion, in either direction, from
said shaft to the vertical shaft first referred to; all substantially as and for the
purposes herein before described, and illustrated in the drawings hereunto annexed.
