Improvements in Means or Apparatus for Drying Grain and other
Materials.
I, SAM SMITHSON of Brides Cottage, Heckmondwike, in the County of York,
Drysalter, 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 my invention is to construct apparatus for drying grain and other
materials, without in any way injuring such materials, and at the same time being
of such a form that the operation of drying is much simplified.
In the accompanying drawings Fig. 1 is a side elevation and part section, and
Fig. 2 a cross section through AB Fig. 1.
For the above purpose I provide a metal drum A, partially closed at each end B
and C, having projecting bosses D and E. On these bosses are fixed their
respective V pulleys F and G.
The drum A is supported through the V pulleys F and G, on small runners H
and I, which are mounted on the brackets J and K attached to suitable supports M
and N. The drum A is caused to revolve on the supporting pulleys or runners H and I
through bevel gearing P actuated from some convenient motor.
The heat for producing the drying operation within the drum A is supplied from
a suitable stove or furnace, such heat passing into the drum A through flue R and
hollow boss E, and after passing through such drum A, the waste heat is conducted
away through hollow boss D, box U, and thence to chimney V.
For the purpose of feeding the material into the drum A I provide a hopper W
which conducts the material put into it to a central receiver or tube X. From this
tube X such material is pushed forward into the drum A by means of the piston Y,
actuated from some suitable motor.
In order to prevent the material being drawn away from the drum A by the
aforesaid chimney V at the end B, I provide a network or perforated disc Z, such
network or perforations being so small as to allow only the smallest and useless
particles to pass off with the waste heat.
In order to agitate the material whilst the drum A is revolving, I provide the
shelves 2 fixed longitudinally in the drum A. and a slight angle, such angle being
given for the purpose of imparting to the material whilst the drum is revolving, a
movement in the direction of the outlet 3, from which the material passes as it is
dried, onto the floor or other convenient receptacle.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The arrangement and application of revolving drum A, with its agitators or
shelves 3, and parts connected therewith, actuated or operated, substantially as and
for purposes herein set forth.
2nd. The arrangement of hopper W, in combination with tube X and piston Y,
for feeding the material into the drum A, substantially as herein set forth.
3rd. The means or method of transmitting or conveying the required heat for
the drying operation, substantially as herein set forth.

page_text: 4th. The general arrangement, construction, and combination of the various parts
forming the means or apparatus for drying grain and other materials, substantially
as herein set forth.
