PROVISIONAL SPECIFICATION.
Improvements in Conveyers for Transporting Coal and other
Materials.
I, FRANCIS LEY of Vulcan Iron Works, Derby, Engineer, do hereby declare the
nature of this invention to be as follows:-
⑆-
Convoyers for transporting coal and other materials are commonly made of an
endless chain having plates fixed to its links and passing over two pulleys. The
plates sometimes simply abut against each other and sometimes they overlap, but in
both cases there are spaces between the adjacent plates at the places where the
chain passes around the pulleys, the result being that the material is apt to drop
through.
According to this invention I make the plates to overlap each other, and 1 curve
the overlapping parts to a suitable radius, so that the plates still remain in contact
even when the chain is hent as it passes around the pulleys.

COMPLETE SPECIFICATION.
Improvements in Conveyers for Transporting Coal and other
Materials.
I, FRANCIS LEY of Vulcan Iron Works Derby Engineer do hereby declare the
nature of this Invention and in what manner the same is to be performed to he
particularly described and ascertained in and by the following statement :-
Conveyers for transporting coal and other materials are commonly made of an
endless chain (or chains) having plates fixed to its links and passing over pulleys.
The plates sometimes simply abut against each other and sometimes they overlap,
but in both cases there are spaces between the adjacent plates at the places where
the chain passes around the pulleys, the result being that the material is apt to drop
through.
According to this Invention I make the plates to overlap each other and I curve
the overlapping parts to a suitable radius, so that the plates still remain in contact
even when the chain is bent as it passes around the pulleys.
In order that my said Invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annoxed.
DESCRIPTION OF THE DRAWINGS.
Invention.
Figure 2 is a transverse section of the same.
Figure 3 is a side elevation of some of the parts drawn to a larger scale.
a is the frame. b the supply hopper. cc the chain pulleys and d d the chains
all these parts may be constructed as heretofore; ee are the carrying plates, they
are bolted to lugs on the links of the chain; and their peculiarity is that they are
bent at their edges so as to render them at these parts concentric with the joint pins
of the chain and so that one plate overlapps the other. The overlapping ends lie
in contact or nearly so as is clearly seen in Figure 3. This figure also shows the
positions which the carrying plates take when passing around the pulley, notwith-
standing the deflection of the chain from the straight course the carrying surface still
remains continuous.

page_text: Having now particularly described and ascertained the nature of my said Inven
tion, and in what manner the same is to be performed 1 declare that what I
claim is :-
A conveyer for transporting coal and other materials in which are carrying plates
socured to a chain or chains passing around pulleys and in which the carrying plates
overlap and are bent at their edges so as to render them at this part concentric with
the joints of the chain substantially as described.
