Improvements in or relating to Shoots for the Delivery of Flour,
Grain, or other Pulverized or Granular Materials, or the like.
We, DANIEL HALL and JAMES HENRY KAY, both of Stockport Road, Ashton-
under-Lyne, in the County of Lancaster, Tin-plate Workers, do hereby declaro the
nature of this invention to be as follows:-
This invention relates to the construction of means for delivering flour grain or
the like, such as formed the subject of Letters Patent No. 21,497 granted to ourselves
and dated September 29th, 1896.
The principal object of this invention is to render the shoot and its adjuncts
more applicable to the delivery of flour or the like in large quantities without fear
of overflow, or waste.
Instead of providing the shoot with a horizontal projecting bottom chamber or
recess open at the front, as before described in the Specification of our Letters
Patent above named, we form the bottom semicylindrical in cross section so that the
bottom of the shoot curves downwards and outwards and then upwards again,
forming a kind of trough well or bin open at the front and about twice the width of
The front of the shoot
the depth of the shoot and as long as the shoot is broad.
is stopped sufficiently short of the bottom and brought forward to allow of the
application of a hinged and pocketted door or cover similar to that described in the
Specification of our former patent. And from the lower edge of the front of
the shoot to the centre of the curved bottom we form a curved slide or groove at
each side of the shoot the central point of this curve being nearest to the back of
the said shoot.
The upper half (or more) of this curve is backed by a similarly curved plate or
partition leaving an opening at the bottom of the shoot accessible from the
doorway of the trough or bin, when the door is let down on its hinge.
A curved plate or damper can slide in the curved slides or grooves and is provided
with suitable handles, and a spring rod passing through a convenient bracket fixed
to the curved partition above named and provided with teeth or notches engaging
with this bracket so that the opening beneath the lower edge of the partition can
be entirely closed or fully opened or opened to any desired extent.
A suitable foot or casting is provided to support the bottom of the shoot from the
floor.
The shoot itself is made of oblong, rectangular form wider than it is deep, and
one or more internal ribs are formed in its length by making the shoot of two or
more lengths of-sheet metal the edges of which are bent inwards one bent round
the other. This will strengthen the shoot very much and will afford means for con-
necting the front and back of the shoot together by transverse tie bars or rods,
without external bolts and nuts or rivets.
These tie bars or rods will furthermore assist any one who cleans the shoot to
climb up inside it and will also assist in breaking up the flour or the like in the
shoot and preventing it from binding together.
When the flour reaches the bottom of the shoot it will be guided and assisted to

page_text: flow outwards into the outer part of the trough or bin by the curve of its bottom
plate, and by the curve of its damper if the same is partly closed.
The partition and damper being curved allow a maximum of space in the outer
part of the trough or bin for the insertion and manipulation of the scoop for with-
drawing the flour.

Improvements in or relating to Shoots for the Delivery of Flour,
Grain, or other Pulverized or Granular Materials, or the like.
We, DANIEL HALL and JAMES HENRY KAY, both of Stockport Road, Ashton-
under-Lyne, in the County of Lancaster, Tin-plate Workers, 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 the construction of means for delivering flour grain or
the like such as formed the subject of Letters Patent No. 21,497 granted to
ourselves and dated September 29th, 1896.
The principal object of this invention is to render the shoot and its adjuncts
more applicable to the delivery of flour or the like in large quantities without fear of
overflow, or waste.
Our invention will be readily understood from the following description on
reference to the accompanying drawings which illustrate the manner in which we
prefer to carry our invention into practical effect.
Fig. 1 is a vertical section of a flour shoot made according to this invention.
Fig. 2 is a horizontal section through the line A-B on Fig. 1, and Fig. 3 is a
similar section through the line C-D on Fig. 1.
Instead of providing the shoot a with a horizontal projecting bottom chamber
or recess open at the front, as before described in the Specification of our Letters
Patent above named, we form the bottom semi-cylindrical in cross section (as seen
at a Fig. 1) so that the bottom a¹ of the shoot curves downwards and outwards and
then upwards again, forming a kind of trough, well, or bin, open at the front and
about twice the width of the depth of the shoot a and as long as the shoot is broad.
The front of the shoot a is stopped sufficiently short of the bottom a and brought
forward at a² to allow of the application of a hinged and pocketted door or cover
b similar to that described in the Specifiation of our former Patent, (c being a
sliding catch or latch to secure the door when closed). And from the lower edge of
the front of the shoot a to the centre of the curved bottom a¹ we form a curved
slide or groove d at each side of the shoot, the central point of the curve of these
grooves being nearest to the back ax of the said shoot a (see Fig. 3).
The upper half (or more) of this curve is backed by a similarly curved plate or
partition a³, leaving an opening at the bottom of the shoot accessible from the
doorway of the trough or bin a when the door bis let down on its hinge.
A curved plate or damper e can slide in the curved slides or grooves d and is
provided with a suitable handle f, or handles, and a hinged or spring rod g passing
through a convenient bracket h fixed to the curved partition a³ above named, and
provided with teeth or notches g' engaging with this bracket h so that the opening
beneath the lower edge of the partition a³ can be entirely closed or held fully
opened, or opened to any desired extent.

page_text: A. suitable foot or casting i is provided to support the bottom a¹, or each side of
the bottom, of the shoot a from the floor.
The shoot a itself is made of oblong, rectangular form (see Fig. 2) wider than it
is deep, and one or more internal ribs at are formed in its length by making the
shoot of two or more lengths of sheet metal the edges of which are bent inwards
one bent round the other as shewn detached and enlarged at Fig. 2. This will
strengthen the shoot very much and will afford means for connecting the front and
back of the shoot together by transverse tio bars or rods k, without external bolts
and nuts or rivets.
These tie bars or rods will furthermore assist any one who cleans the shoot to
climb up inside it, and will also assist in breaking up the flour or the like in the
shoot and preventing it from binding together.
When the flour reaches the bottom of the shoot it will be guided and assisted to
flow outwards into the outer part of the trough or bin by the curve of its bottom
plate a', and by the curve of its damper e if the same is partly closed.
The partition a³ and damper e being curved allow a maximum of space in the
outer part of the trough or bin a for the insertion and manipulation of the scoop
for withdrawing the flour.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The combination with a delivery shoot of a curved trough or bin suitably
supported at the lower end thereof and open at the upper front part, being pro-
vided with a suitable door or cover and a curved internal position and curved
sliding damper substantially as hereinbefore described.
2. A delivery shoot having an internal rib or ribs at front and back so that the
bars or rods can be applied to the shoot without external bolts or nuts and rivets
substantially as hereinbefore described.
