We SAMUEL RICHARDSON 69 Victoria Road Leeds in the City of York,
Yorkshire, Tin, Iron, Zinc, and Copper Plato Worker, and ENOCH WILKINSON
8 Lascolles Terrace, Roundhay Road Leeds, Co-operative Store Manager, do
hereby declare the nature of this invention to be as follows :—
In carrying out my invention we have the following objects in view.
1. To provide a suitable apparatus by which means flour can be transmitted from
one floor to lower floors and so designed as to keep the flour in a light and fluffy
condition and to prevent it forming a hard mass during its passage down the shoots.
2. And to construct it of sheet zino or other suitable material to prevent the
propagation of filth such as wood shoots encourage.
8. And to provide an easy means of opening the bin or receiver thereby
allowing it to be opened without any, undue exertion of the attendant.. And to.bo
constructed as follows.
Referring to drawings
Fig. 1 is a side elevation. Fig. 2 a front elevation without covers on bin showing
one bin open and the other closed.
Fig. 3 plan showing top of shoots & huppera.
Fig. 4 plan showing one shoot in section and one receiver in section.
a is the hopper in the shape of a rectangular box, into which the flour is placed
from the sacks, and aufficiently large to feed two shoots. There is also a lid to
cover up hopper not shewn in drawing. is a shield.round the ends and back,, to
prevent the flour from overflowing when emtied from the flour bags. c. c. are
triangular sectioned breakers stretching across the inside of the shoots, to split up
the flour and prevent it conjealing. d. d. d. are bearers about one third the dia. of
the shoot and strengthened by struts underneath to support the flour. e. e..are the
shoots built up in convenient lengths and diameters. ... shows how the. lengths
are joined together by one being made slightly taper to wedge into the other.
g. g. are the bottom. receivers or bins made with a sloping bottom & front to
prevent waste. hh are the, hand levers for opening sliding door, working on
centre ii and conected to the vertical conecting rod which slides through holes
in fixings k. k. therefore always keeping the rod in a vertical line.. Conecting rod j.
is in turn attached to the double lever or beam l: oscillating on centre.m. theu to
slide rod, n. which slides through socket o.
All the connections between the rods & levers are by pins working in slots in the
levers. The slide rod . is next attached by screws to the wood sliding door p.
which is bevelled at the bottom and tipped with zinc, to cut through the flour.
Q. Q. are corner pieces forming the groves in which the door slides, r. is the
opening in the bin to permit the flour being scooped ont when required. .. are
the guards to prevent any unnecessary motion of the levers h. h. t. t. are lids
hinged at uu. to cover up the bins when not in use. v. r. are handles on lids t. l.
Thus it will be seen from the forgoing description that when the flour is put in
the hoppers a. a. it falls upon the top breakers c. c. then on bearers d. d. d. sliding.
from one to another until it reaches the bottom breakers c. c. then is again broken
up and reaches the bin in a light condition.

An Improved Combined Flour Shoot and Receiver or Bin, and
Apparatus for Opening the Bin.
We SAMUEL RICHARDSON of 69 Victoria Road Leeds in the County of York
Tin Iron Zino and Copper Plate Worker and ENOCH WILKINSON of 8 Lascelles
Terrace Roundhay Road Leeds in the County of York Co-operative Stores
Manager 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 :-
The object of our invention is to provide suitable apparatus by means of which
flour can be transmitted from a higher to a lower floor, and during such transmission
to retain the flour in a light and "fluffy" condition, and to prevent it forming a
compact mass during its passage down the shoots or on reaching the bottom of the
bin, and further to provide easy means for opening the bin or receiver without
undue exertion on the part of the attendant.
And in order that our invention and the manner in which the same may be
performed may be more readily understood, reference will at once be had to the
drawings accompanying our Provisional Specification of which
Fig. 1 is a side elevation, Fig. 2 a vertical section and Fig. 3 a plan shewing the
top of the shoots and hoppers.
Fig. 4 is a plan shewing one shoot and one receiver in section.
a is the hopper preferably rectangular in shape into which the flour is emptied
from the sacks and which is sufficiently large to feed two shoots. The hoppor is
usually covered by a lid not shewn in the drawings.
bis a shield round the ends and back of the hopper to prevent the flour from
overflowing when emptied from tho bags or sacks.
ee are the separate lengths of the shoot or shoots and may be rectangular or
circular in section. ce are "breakers" preferably triangular in section, with the
apex upwards, placed in suitable positions, and stretching from side to side or end
to end of the shoot. These breakers are for the purpose of splitting up any con-
siderable body of flour which may be passing down the shoot in a compact body.
Where two breakers are provided, the one is placed at right angles to the other,
and where more than one breaker is provided they may be placed at other suitable
'angles (as viewed in plan) with respect to each other.
dd are side deflectors, each of which covers about one third the sectional area of
the shoot as seen in plan. These are for the purpose of breaking the fall of the
flour, and preventing it becoming consolidated on reaching the bottom of the shoot.
The various lengths of the shoot are joined together in a flour tight manner by
making the lower end of each length taper, as shewn at f,, so as to wedge tight
into the top of the next lower length.
9, 9, are the receivers or bins made with a sloping bottom and front so as to avoid
waste of flour: For this same reason the lowest deflector is so placed as to deflect
the fall of the flour towards the back part of the bin or receiver.
h, h, are hand levers centred at ii, for opening the sliding door. Theso are
connected to the vertical, rod j, which slides through the holes in the guides k, k.
The opposite end of the connecting rod is attached to one end of the double armed
lever, which is pivotted on the centre m, and the opposite end of the lever / is
connected by means of the slide rod n (passing through the guide o) with the
eliding door p. This door is bevelled at the bottom and tipped with zinc in order
to cut through the flour and make a tight joint. 9, 9, are corner pieces forming
the grooves in which the door slides. is an opening in the bin to permit of the
flour being scooped out when required. 8, s. are guards to prevent any unnecessary
motion of the levers h, h. t, t, are lids hinged at u, u, for the purpose of covering
up the bins, when not in use. Tv, are the lid handles.

page_text: When the flour is put into the hoppers, it falls first upon the top breaker and
deflectors, and afterwards on to the bottom breaker and deflectors, so that the
speed of its descent is checked, and any tendency to form a consolidated mass is.
prevented by the above arrangement, so that the flour reaches the bottom in a
light and "fluffy" condition.
We wish it to be understood that we do not limit ourselves to any particular
number or arrangement of the breakers and deflectors.
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. Qui improved combined flour shoot and bin substantially as herein set forth.
2. In connection with flour shoots the arrangement and use of either or both-
deflectors placed at alternate sides of the shoot-and breakers placed at intervals
across the shoot, for the purposes herein set forth.
8. The combination of a bin (or receivor) having a bottom sloping towards the
back of the bin with a shoot having a deflector so placed near the bottom of the
same as to direct the fall of the flour towards the back of the bin.
4. The combination of a flour shoot provided with either or both breakers and
deflectors, with a bin having a bottom sloping towards the back of the biu.
