PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Conveying or Elevating Materials.
I GEORGE PAULIN of Lion Cement Works West Thurrock in the County of Essex
Engineer do hereby declare the nature of this invention to be as follows:-
The object of my Invention is to provide a simple durable and efficient apparatus
for conveying or elevating materials in which apparatus many of the objections
applying to ordinary apparatus of this class are obviated.
According to my Invention I provide a tube or cylinder which is mounted at con-
venient intervals in bearings so that the said tube or cylinder can be rotated therein
by any suitable motor antifriction rollers being provided in the said bearings for the
tube or cylinder to run upon if desired. On the interior pheriphery of this tube or
cylinder form or fix so as to rotate therewith a helical web or blade or female screw
extending from end to end of the tube or cylinder. The tube or cylinder is of a length
and is situated in a horizontal vertical or angular position so that it extends from the
place from which the material is to be conveyed or elevated to the place at which it is
to be delivered. The bearings being external great facility is given for lubrication
and there is moreover no danger of the material conveyed being contaminated by
lubricant.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Conveying or Elevating Materials.
I, GEORGE PAULIN of Lion Cement Works West Thurrock in the County of Essex,
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 :-
The object of my Invention is to provide a simple durable and efficient apparatus
for conveying or elevating materials in which apparatus many of the objections
applying to ordinary apparatus of this class are obviated.
According to my Invention 1 provide a tube or cylinder which is mounted at
convenient intervals in bearings so that the said tube or cylinder can be rotated
therein by any suitable motor, antifriction rollers being provided in the said bearings
for the tube or cylinder to run upon if desired. On the interior periphery of this
tube or cylinder I form or fix so as to rotate therewith a helical web or blade or
female screw extending from end to end the tube or cylinder. The tube or
cylinder is of a length and is situated in a horizontal vertical or angular position
so that it extends from the place from which the material is to be conveyed or
elevated to the place at which it is to be delivered. The bearings being external
great facility is given for lubrication and there is moreover no danger of the material
conveyed being contaminated by lubricant.
Figure 1 of the accompanying drawing represents in vertical longitudinal
section and Figure 2 in plan an apparatus constructed according to my Invention
illustrating what I consider the best way of carrying it out in practice. A. is the
tube or cylinder mounted in bearings of which two are shewn at B. B. They are
provided with antifriction rollers bb upon which the tube or cylinder A. rests. The
straps of the bearings have a web which enters a groove a in the tube or
cylinder A. to guide it. The tube or cylinder A. is provided with any suitable
means for rotating it. I have shown for this purpose a bevel wheel C secured to

page_text: On
the tube or cylinder A. with which engages a bevel wheel D on a shaft provided
with a driving pulley d over which passes a strap from any suitable motor.
the interior periphery of the tube or cylinder A. is formed or fixed the helical web
or blade or female screw A' extending from end to end of the said tube or
cylinder A. E is a hopper by which the materials to be conveyed are introduced
the said materials entering the tube or cylinder A. and as it and the helical web
or blade or female screw A³ within it rotate the said materials are moved along
to the other end of the tube which is situated at the place where the materials are
to be delivered and at this place the materials are eventually discharged from the
tube or cylinder A. The said tube or cylinder may be of any suitable length or
there may be several lengths, one length delivering the materials into the next
succeeding length either directly or by means of a hopper.
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 :-
1. In apparatus for conveying or elevating materials a tube or cylinder provided
with a helical web or blade or a female screw secured to or formed in one with the
said tube or cylinder and means for causing both the tube or cylinder and the helical
web or blade or female screw to rotate together substantially as herein before described.
2. An apparatus for conveying or elevating materials the said apparatus being
arranged or constructed as hereinbefore described and illustrated in the accompanying
drawings.
