COMPLETE SPECIFICATION.
Improved Apparatus for Conveying Light Granulated and Fibrous
Substances and the like.
We, JOHN FRANCIS WHITE and JOHN HURRY, both of 168, Thornton Road,
Bradford, in the County of York, Engineers, 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 that is to say:-
It relates to apparatus for conveying light granulated and fibrous
substances such as saw-dust, wood-chippings, cotton, wool and the like
and consists in constructing and arranging said apparatus so that said substances
may be received by same, as they are being produced, or as they leave any of the
varied machines by which they have been treated, and conveyed to other machines
or to other parts or places wherever and as desired.
In carrying our invention into effect we follow the method of constructing
and arranging the apparatus hereinafter explained and as illustrated by the
accompanying sheets of drawings, wherein :-
Fig. 1 is a sectional elevation illustrating our improved apparatus as applied
for conveying substances to the several rooms of separate buildings.
.
Figs. 2 and 3 are sectional side elevation and end view of a certain part of our
apparatus hereinafter described the same being drawn to an enlarged scale.
Figs. 4 and 5 are side and sectional end elevations of a blower or fan which
forms part of our improved apparatus.
Fig. 6 is a drawing in detail of a modification hereinafter explained.
To attain the object of cur invention, when our apparatus is to be used in
connection with a machine producing or treating the substance that has to be
conveyed, as is the case when sawdust, wood chippings or the like are being
produced, or when cotton or other fibrous substance is being treated by any of
the well known classes of machines to which it is subjected, or when wool has
been discharged from the machine in which it has been washed (the discharging
end of which latter may be taken as being represented at a Fig. 1), we arrange
the receptacle to receive such substance or wool which is then drawn through
the fan or blower c (constructed as hereinafter described) to be further forced
by the current of air circulated by said fan c, along the conduits & to be deposited
in any of the rooms or places wherever it is desired to be carried.
When the conduits d are laid in several rooms or places as at e, f, g or to lead
from one building h to the roomis km of another building into any one part or
place of which rooms or buildings it is desired to carry the substances to be
conveyed, we mount switches p p (constructed as hereinafter explained) at any
positions where the conduits lead in two directions, and to these switches p we
attach chains, cords or the like so that by arranging said chains,. cords or the
like to lead from said switches into proximity with the machine as at a or
otherwise to lead to such a position as to bring them immediately under the
control of the operative, it will be seen that such operative may move said
switches so that the substance being conveyed may be conducted to any part
desired.

page_text: We construct the fan or blower to have an opening at c¹ for the ingress of
the substance to be conveyed and this we are enabled to effect by mounting the
blades on their shaft which is supported on the opposite side of the
opening by the bearings thus the current of air started in motion by
the rotary blades el enters by the opening e¹ and passes out by the opening
carrying with it the substances that have to be conveyed. The blades care
of the shape shown and by being mounted as described, cause the substances
being conveyed to follow the proper course and not to interfere with the actions
of the shaft or the bearings in which it rotates.
The switches are constructed by having a hinged plate p₁ formed to fill the
cavity, in which it is mounted, in both directions as is shown in full lines as
well as in broken lines Fig. 2.
The plate is hinged at 7 and by its arm g may be forced through the retracting
of the spring into the position shown by broken lines Fig. 2 in which case the
current would travel in the direction of the arrow e, while by the chain or cord s
being secured to the arm t the operative may move said plate into the position
shown by full lines of the same figure in which case the current would follow
the course indicated by the arrow ¹.
The plate is pivotally mounted in such a position within its casing as will
enable it to close and open the course for the current of air as desired, in some
cases the pivotting of this plate being in the position shown by Fig. 2, in
others it will be in the position shown by Fig. 6.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is; -
1. Apparatus for conveying substances the same being constructed and
arranged to operate substantially as herein specified.
2. In apparatus of the class described, fan or blower and switch mechanisms
the same being arranged to operate substantially as herein set forth.
