COMPLETE SPECIFICATION.
Device for Consecutively Delivering Equal Quantities of Granular
or Pulverized Materials from a Receptacle.
I, HEINRICH BLANKE, Engineer, Proprietor of the Firm of Blanke & Rast,
Manufacturers of Leipzig-Plagwitz, Germany, do hereby declare the nature of
my invention and in what manner the same is performed to be particularly
described and ascertained in and by the following statement :-
The present invention consists of a device for consecutively delivering equal
quantities of granular or pulverized materials from a receptacle and also of
suitable means in connection with such receptacle to shake or agitate the contents
of the same and thus to render it possible to extract the whole of the said
contents.
And in order to render the present Specification more easily intelligible reference
is had to the accompanying drawing in which similar letters of reference denote
similar parts throughout the several views:-
Fig. represents in side elevation partly in section and in sectional plan one
form of carrying out my invention,
Fig. 2 shows a modified form in sectional side elevation and detail sectional
plan,
Fig. 3 a part transverse sectional elevation of a further modification,
Fig. 4 part sectional elevation and plan of a modification and
Fig. 5 a plan of a modified form of a device for shaking or agitating the contents
of the receptacle.
The device illustrated in Fig. 1 consists of a receptacle a at the bottom a¹ of
which is arranged a guide casing communicating with the said receptacle by
means of an opening. In this casing is guided a rod d having handle ff and
carrying a chamber c. At the front end of the casing is an outlet opening i
whilst the said chamber c is provided with a rearwardly extending cover fadapted
to close the opening i when the chamber c is pulled forward, the bottom of the
said chamber is formed by the bottom of the guide sleeve or casing b. A spring d¹
serves to normally hold the chamber c under the opening the bottom of said
chamber being closed by the bottom of the casing.
The device operates in the following manner :—
When the chamber c is in its normal position under the opening of the
receptacle a, the contents of the latter will fall into and fill the same, on pulling
the said chamber forward by means of rod d and handle ff, it will be brought
over the opening of the casing and the portion of granular or pulverised material
contained therein will find exit at the opening i to the receptacle being closed by
the rearwardly extending cover f. Obviously on repeating the operation the
same quantity of material will be extracted from the same at each movement of
the chamber c.
Fig. 2 shows a modified construction in which two chambers c¹ and c 2 are
employed being arranged to turn in a casing on a central pivote by means of a
lever arm extending through a horizontal slot in said casing. A cover c3 to
which the said chambers are fitted closes the opening i to the receptacle whilst
The
the chambers are being turned to come alternately into communication.
pivot v may be made to extend upwardly through the bottom of the receptacle and
be provided at its upper end with stirrer arms as shown. This device is double
acting as will be evident one chamber being filled whilst the other is emptying.

page_text: In Fig. 3 a vertically rotating drum having depressions n to receive the material
is adapted to rotate on a pivot m and bring the said cups or depressions_n
consecutively under the opening i of the receptacle and empty the same at the
opening of the drum casing 1. A suitable lever may be keyed to the spindle m
in order to rotate the drum.
Thus
In Fig. 4 a casing is mounted on one end of a flat lever p having an arm s
and pivoted to the bottom of the receptacle at o. Beneath the casing bottom the
chamber is covered for a part of its stroke by a suitable housing u.
when the said casing is in communication with the opening i of the receptacle its
open end is closed by the casing u. On throwing over the lever P the said
casing with its contents is brought out of the casing u and the opening i closed
by the arms. As soon as the chamber rleaves the casing u the contents are free
to fall out of the same.
In order to shake or agitate the casing so as to render it possible to extract
the whole contents from the same, the receptacle a (Fig. 1) is pivoted by means
of suitable lug aa and pivot u' to a support d d so that its centre of gravity is
helow the pivot and its lower rim consequently rests against the said support d d.
On pulling the handle ff to operate the chamber the lower end of the receptacle
will be raised from the support d d, and on releasing the handle the said receptacle
will fall back striking the support and shaking or agitating the contents.
In Fig. 5 another form of agitating device is shown according to which the
receptacle a is mounted in suitable bands g g on the support ad and may be
turned in the same being returned suddenly on release by a spring / h fixed at one
end to the receptacle and at the other to the support d.d.
These shaking or agitating devices may be employed in connection with any of
the modifications described.
Other suitable shaking or agitating devices may also be employed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is :-
A device for consecutively delivering equal quantities of granular or pulverised
materials from a receptacle, and for suitably agitating said receptacle consisting
(1.) Of the arrangement of one or more chambers c and of inlet and outlet
openings so that the said chambers may be slid or rotated from the inlet to
the outlet and back alternately each emptying the material taken up from the
receptacle at the outlet at each movement substantially as described.
(2.) Of means for imparting a swinging or rotary movement to the receptacle
to shake or agitate the contents of the same in the manuer substantially as
described.
