COMPLETE SPECIFICATION.
A New or Improved Device for Moving Grain, Sand, or other
Loose Material.
I, JULIUS THEODOR KARL ESOHHOFF, of Harburg, in the Empire of Germany,
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 :-
This invention has for its purpose to provide a simple, cheap and durable device for
moving grain, coal, sand or other loose material, in the manner of the transport worm
and strap elevator, in an approximately horizontal direction.
Referring to the accompanying drawing,
Fig. 1 is a longitudinal section.
Figs. 2 and 3 are cross sections of the improved contrivance, which consists of a
tapering tube T being of circular or other convenient cross section and provided at its
extremities with pivots Z Z so lodged as to allow the tube to be revolved about its
horizontal axis. The device is actuated by means of a strap pulley or wheel R
provided on said pivots. The tube, corresponding to its length is provided with one
or more strengthening rings or hoops S, the outer surface of which is supported by
roller bearings (Fig. 3).
The material fed to the narrow end of the tube through a fúnuel F, is taken along,
when the tube is in rotation, owing to the adhesion of the inner sides of the tube, and
subsequently falls down again by its own gravity. Once in movement, the grain or
other material slides down the inclined plane, formed by the conic or tapering shape
of the tube at the bottom thereof, and leaves the apparatus at the broad end, the rim
of which is bent round outwardly.
The rim of the narrow end of the tube is bent round inwardly in order to obviate
any loss of material at the inlet.
The conic or tapering tube may be replaced by a cylindric or prismatic tube, the
axis of which gradually declines in the direction of movement.
For great distances, a convenient number of apparatus are so combined or super-
posed as to allow the material to fall from one tube into the funnel of the other until
it reaches its destination.
Considering its great simplicity in construction, the improved device is obviously
preferable to any other similar means, and the frequent disturbances attendant on the
use of the latter through injury to part of the contrivance, are almost excluded.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1) The application, for moving grain or other loose material in an approximately
horizontal direction, of a tapering tube T of suitable cross section adapted to revolve
about a horizontal or inclined axis, substantially as set forth.
2) The application for the purpose stated in Claim 1, of a cylindric or prismatic
tube adapted to rotate about an inclined axis, substantially as set forth.
3) The combination, for great distances, of a suitable number of the devices
embodied in claims 1 and 2, substantially as set forth.
Dated this 1st day of July 1889.
