COMPLETE SPECIFICATION.
Improvements in Conveyor Apparatus.
1, WILHELM HUDEL, of Schönbach, near Herborn, Wiesbaden, in the Empire
of Germany, Millwright, 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 consists of improvements in apparatus for conveying or shifting
meal and other similar substances, whereby an apparatus is produced which is
distinguished from apparatus of the kind heretofore in use by the fact that the
screw or worm is so connected with the casing or cover that both rotate together,
whereas in conveyors hitherto used the screw is adapted to rotate within a fixed
casing or cover. As, however, in such cases, the screw does not accurately fit the
casing or cover, it necessarily follows that some of the substance (meal, for example).
lodges in the joints and spaces, which consequently afford harbouring places for all
kinds of vermin, and this is more especially the case when the screw is adapted to.
turn in a square or polygonal casing or cover.
Such appliances are therefore objectionable on hygienic and other grounds, and
the object of this present invention is to so construct the apparatus as to prevent
any such retention of the meal or other substance in the joints or corners.
In the accompanying drawing,
Figure 1 is a longitudinal section of a portion of an apparatus constructed in.
accordance with this invention,
Figure 2 is a transverse section on line x-x of Figure 1.
Figure 3 illustrates in longitudinal section an arrangement in which a multiple
screw is employed, and
Figure 4 is a transverse section on line y-y of Figure 3.
In the arrangement illustrated in Figures 1 and 2, a is the shaft on which the
screw bis mounted. This screw b is surrounded by a casing or cover c on which is
a suitably arranged pulley d, for the purpose of enabling the whole apparatus to be
set in rotatory motion.
The substance is introduced through the inlet E. This inlet, as may be seen in.
Figure 1, is introduced into the ends of the casing or cover c, and is adapted to
remain stationary whilst the casing or cover c, with the screw b, is rotated. The
screw traverses the inlet E as shewn, and thus removes all the meal therefrom to
the interior of the rotating casing or cover c.
If, instead of a single screw b, two such screws b' b2 (see Figure 3) are employed,
a second similar inlet E' is provided, as shewn in Figure 4. This inlet is also
fixed, and is made to surround the casing or cover, the opening e' in the casing or
cover (which opening is indicated by partly dotted and partly full lines in
Figure 3) being of a spiral form corresponding with the screw. By this means the
meal or other substance can only fall into the proper compartment formed by
means of the separate screws, that is to say, the meal or other substance intro-
duced at the inlet E is kept separate from that introduced at the inlet E¹.
The different sorts of meal or other substances are thus conveyed through the
apparatus independently of one another; a result which it is impossible to attain
by means of the appliances heretofore in use. It is obvious that as many inlets
can be provided as there are screws and different sorts of meal to be acted upon.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
First. The improvement in apparatus for conveying or shifting milled, ground,
or other similar material, the distinguishing feature of which is that the screw or
worm is so connected with the casing or cover that both rotate together,
substantially as described.
Second. In couveying apparatus of the kind herein described the arrangement
of a multiple screw, so that several sorts of meal or other substance may be
conveyed independently of one another, substantially as described.
Third. In conveying apparatus of the kind herein described the arrangement of
an inlet E,arranged to deliver into the casing or cover c, with or without other
inlets surrounding the sides of the said casing or cover, with openings in the
casing or cover corresponding in shape to the screws, for the purpose of enabling
different sorts of substances to be acted upon independently of one another,
substantially as described.
Dated this 8th day of September 1896.
