PROVISIONAL SPECIFICATION.
Improvements connected with Endless Conveyers for Coals and
other materials.
I, SAMUEL POTTS, of Greenfield, Hamilton, in the County of Lanark, North
Britain, Engineer, do hereby declare the nature of this invention to be as follows,
that is to say :-
My said invention relates to endless conveyers such as are used for conveying
coals or other materials in cleaning or separating or other machinery. The
conveyers referred to consist of plates connected together and moved along by
means of endless chains, the series of plates and chains passing round polygonal
drums or pulleys which, or some of which, are driven and act on the endless
chains with sprockets or teeth. Owing to the sizes of the drums the coals or
other materials have a considerable distance to fall at the end of a conveying
stretch, where the conveyer passes round and under the drum, and the coals or
materials become broken in an undesirable manner; and it is the object of the
present invention to prevent the breakage thus occasioned.
In carrying out the invention an inclination is given to the conveyer at the
end of a stretch by arranging two drums, an upper one at the main level and a
lower one placed at a suitable distance from the upper one so that the conveyer
may have the desired inclination between them; and just beyond the lower drum a
guide plate is arranged to receive the coals or materials as they pass off the
conveyer in the inclined direction, the inclination making them move in that
direction, and allowing of the receiving guide plate being brought quite near the
point at which they leave the conveyer.
The conveyer plates are arranged to overlap each other; and each overlapping
edge may lie in a rebate or sunk part in the edge of the next plate. With this
arrangement of the conveyer plates the receiving guide plate may have its edge in
contact or nearly so with the conveyer plates just above the lower drum. The
overlapping parts and the rebates are made so that the guide plate will not catch
as the conveyer plates pass under its edge.

COMPLETE SPECIFICATION.
Improvements connected with Endless Conveyers for Coals and
other materials.
I, SAMUEL POTTS, of Greenfield, Hamilton, in the County of Lanark, North
Britain, 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, that is to say :-
My said invention relates to endless conveyers such as are used for conveying
coals or other materials in cleaning or separating or other machinery.
The conveyers referred to consist of plates connected together and moved along
by means of endless chains, the series of plates and chains passing round polygonal
drums or pulleys which, or some of which are driven and act on the endless chains
with sprockets or teeth. Owing to the sizes of the drums the coals or other
materials have a considerable distance to fall at the end of a conveying stretch,
where the conveyer passes round and under the drum, and the coals or materials

page_text: become broken in an undesirable manner; and it is the object of the present
invention to prevent the breakage thus occasioned.
In carrying out the invention an inclination is given to the conveyer at the end
of a stretch by arranging two drums, an upper one at the main level and a lower
one placed at a suitable distance from the upper one so that the conveyer may have
the desired inclination between them; and just beyond the lower drum a guide
plate is arranged to receive the coals or materials as they pass off the conveyer in
the inclined direction.
The conveyer plates are arranged to overlap each other; and each overlapping
edge may lie in a rebate or sunk part in the edge of the next plate.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing a simple and convenient arrangement embodying
my improvements.
Figure, 1, is a small scale diagram showing the delivery end of the conveying
apparatus and parts connected therewith.
Figure, 2, is an enlarged vertical longitudinal section of the delivery end of the
apparatus.
Figure, 3, shows a modification of certain details.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
As shown in the drawings the conveyer referred to consists of a number of
plates, A, which overlap each other and extend across the apparatus. These
plates, A, have eyed snugs, B, on their undersides and are connected to a pair of
endless chains, C, by the snugs and by rods, D, which pass through holes in the
links of the chain, C, and through the eyes of the snugs, B. Alternate single
links of each chain, C, pass at the main level of the apparatus between guide
snugs, E, on the surface of a pair of polygonal drums, F, placed one at each side
of the apparatus on a shaft, G, which is carried in bearings in the main framing, H,
of the apparatus.
A suitable inclination is at the delivery end given to the series of plates, A, and
chains, C, forming the conveyer by causing them to pass from the drums, F, to
and round a second pair of similar drums, J, the shaft, K, of which is mounted in
bearings in the framing, H, at a suitable lower level than that of the upper
drums, F, so that the conveyer may have the desired inclination between them.
The lower drums, J, are driven by any suitable gearing (not shown) and move the
endless chains, C, by sprockets or teeth, L. Just beyond the lower drums, J, a
guide plate, M, is arranged to receive the coals or materials as they pass off the
conveyer plates, A, in the inclined direction; the inclination of the conveyer plates
at that part making them move in that direction, and allowing of the receiving
guide plate, M, being brought quite near the point at which they leave the
conveyer plates. With this arrangement of the conveyer plates the receiving
guide plate, M, has its edge nearly in contact with the conveyer plates, A, as
they pass round the lower drums, J; the guide plate being however sufficiently
clear for the conveyer plates not to catch as they pass under its edge.
From the guide plate, M, the coals or materials pass on to the ordinary screen
bars, N, after leaving which they pass (by preference) as shown in Figure, 1, on to
one end of an endless delivery band, P, the outer end of which can be lowered by
suitable mechanism into any desired position, the dotted lines showing the outer
end of this band, P, as lowered into a truck, Q. The delivery band, P, can be
adjusted so that the coals or materials will have the least possible drop into whatever
receptacle is placed for them.
In Figure, 3, is shown a modification in which the overlapping part of each
plate, A, enters a rebated or recessed part of the next plate, so as to form a con-
tinuous flush outer surface when two or more plates are in line. With this
modification the receiving guide plate, M, may be placed very close to the plates, A,
at the inclined part of their course as shown.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :
The improved combination and arrangement of the parts of and connected with
endless conveyers for coals and other materials substantially as hereinbefore described
and as shown in the accompanying drawings.
2. The arranging of the delivery ends of endless conveyers for coals and other
materials with a downward inclination substantially as and for the purposes
hereinbefore described
