PROVISIONAL SPECIFICATION.
Improvements in Bins for Granular or Pulverulent Material, and in
Receptacles for Transferring such Material from said Bins to
other Bins or Receptacles.
I, LEON CAMUS of 15 Rue des Halles, Paris, France, Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention has reference to improvements in bins for granular or pulverulent
material capable of readily flowing from one vessel to another by gravity, as for
examples powdered coal, and grain of various kind, and in receptacles for conveying
such materials from said bins to other bins or holders at a distance, the object being
to enable material of the kind mentioned to be discharged from the bins into the
said receptacles and subsequently from these receptacles into other bins or
receptacles without loss and without causing dust.
A bin according to my invention is made of suitable material such as wood or
sheet metal of determined capacity, of rectangular prismatic or other form in cross
section terminated by an inverted truncated pyramid corresponding to the section
of the box, and the lower and smallest base of which forms the discharging orifice.
This orifice is closed by a flap or disc operated by a lever, and allowing of
regulating the discharge of the material enclosed in the box.
Below this orifice there is placed a pail or other receptacle (hereinafter called a
receptacle) also provided with a lower opening and regulating discharge plate and
forming an intermediary between the bin hereinbefore referred to, and the bin or
other receptacle at a distance to which the material is to be transferred.
After the receptacle is placed under the opening of the bin, the flap or disc of
the latter is opened and the material allowed to run into the receptacle and when
the latter is full, the discharge aperture in the bin is closed by operating the
lever.
The pail is then removed and placed over the receiver into which the materials
are to be discharged; the plate or disc closing the opening of the receiver is caused
to oscillate, and the materials fall into the receiver without having made any dust,
and without losses of materials during the transport of the same having been
incurred.

COMPLETE SPECIFICATION.
Improvements in Bins for Granular or Pulverulent Material, and in
Receptacles for Transferring such Material from said Bins to
other Bins or Receptacles.
I, LÉON CAMUS of 15 Rue des Halles, Paris, France, Engineer, 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:-
My invention has reference to improvements in bins for granular or pulverulent
material capable of readily flowing from one vessel to another by gravity, as for
examples powdered coal, and grain of various kind, and in receptacles for conveying
such materials from said bins to other bins or holders at a distance, the object
being to enable material of the kind mentioned to be discharged from the bins into
[Price 8d.]

page_text: the said receptacles and subsequently from these receptacles into other bins or
receptacles without loss and without causing dust.
In order that the nature of this invention may be clearly understood, reference is
had to the accompanying drawings in which
Fig. 1 is a vertical section of a bin according to this invention; and
Fig. 2 is a sectional plan thereof.
Figs. 3 and 4 are respectively a vertical section and a plan of a receptacle
according to this invention.
Fig. 4 is a detail view thereof.
Fig. 5 is a part plan illustrating a modification.
Referring to Figs. 1 and 2, Ä is a bin made of wood, sheet metal, or other
suitable material, of rectangular form in cross section, of a capacity accurately
determined, and capable of serving as a means of controlling the supply of the
substances. The lower end of this bin is of inverted truncated pyramidal form, the
upper part corresponding to the section of the upper part of the bin and whose
smallest part i.e. the lower one, constitutes the discharge opening B. The bin may
however be of other form than that shewn, and the discharge opening, instead of
being located in the bottom, may be formed in one of the sides. The opening B is
controlled by a pivotted flap or as shewn by a sliding plate C adapted to be
operated in any suitable manner as for example by means of a rod a connected to a
lever provided with a handle c located underneath the bottom of the bin which is
carried by uprights or panels D arranged at two or three sides of the bin, but
which might be replaced by feet or other suitable means of support. The lever b
thus operates beneath the bin and its movement is not in any way hindered. When
the handle (Fig. 2) is moved to the right there can be placed below the opening B
a receptacle of any suitable kind. When the plate C is moved from below the
opening B, the handle e occupies a position in front of the receptacle, and it is no
longer possible to withdraw the latter without closing the opening and without
obviating in consequence, loss of material. The plate C may be maintained in its
closed position by an automatically acting spring or by a counterweight.
When the granular or pulverulent material is to be merely transported, any kind of
receiver or receptacle may be placed under the opening B, but when it is desired to
transfer it from a bin such as hereinbefore described to another bin without loss
and without causing dust, a receptacle is employed of the construction illustrated
on a larger scale in Figs. 3 and 4.
This receiver F may advantageously be of cylindrical form, though it may be of
any other suitable form in cross section. It is formed or provided internally with
a conical hopper H at the lower end of which is a discharging opening H. This
opening is closed by a sliding plate, or as in the example shewn by a metallic disc I
connected to a lever J which can be turned about a pivot d by means of a handle K.
This disc is normally kept in the closed position by a counterweight or spring. In
the example illustrated I have shewn a coiled spring L which is compressed when
the handle K is moved to open the disc. Instead of this arrangement any other
suitable arrangement might be used as for example that shewn in Fig. 5 in which
the closing spring is carried by the lever J and acts against the inner surface of a
part of the wall of the receptacle F.
Below the opening H' is a tubular part M designed to receive or engage with a
conduit of a diameter corresponding to the said tubular part for the purpose of
conducting the material to a required place. When the receptacle is to be
charged with material from the Ein A it is placed under the opening B of the bin
which is then opened. The material then falls from the bin into the receptacle
fills it, and then ceases to flow on account of the diameter of the opening B being
smaller than that of the receptacle and of the proximity of the receptacle to the
bottom of the bin. The plate C is then moved into its closed position and the
receptacle removed, and conveyed to the place where it is to be discharged
The disc I at the bottom of the receptacle is then opened to the required extent
The discharge of the material being regulated, or arrested, as desired. The

page_text: material will have thus been transferred from the bin A to a vessel at a distance
therefrom without causing dust and without loss.
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 :-
1. The improved construction of bin as hereinbefore described with reference to
and shewn in Figs. 1 and 2 of the drawings annexed, for holding granular or
pulverulent material of the kind mentioned, the said bin having a pivotted flap or
sliding plate such as C whereby the discharge of material from the bin to a
receptacle below can be effected without loss and without the production of dust as
set forth.
2. The improved construction of receptacle hereinbefore described with reference
to and shewn in Figs. 3, and 44, or modified according to Fig. 5, for transferring
granular or pulverulent material of the kind mentioned from a bin such as referred
to in the preceding claim, to another bin or holder, the said receptacle having a
sliding or pivotted disc or plate such as I whereby the discharge of the said
material from the said receptacle to a second bin or holder below it can be
regulated and be effected without loss and without the production of dust as set
forth.
