Improvements in Conveyor Chains.
We, HENRY HACK, M.I.C.E., of the City Gas Works, Saltley, Gas Engineer,
and HENRY GILES, of Rose Cottage, Nechells Place, Saltley, Mechanical
Engineer both in the City of Birmingham, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to an improved conveyor chain link, and its object is to
produce a link of simpler construction and greater durability than those hitherto
in use.
We
In one method of carrying our invention into effect we cast the two sides of the
link together, connecting them by a bridge piece passing over the top of the links
between the bolts or snugs used to fasten the conveyor pans upon the links.
thus bind the opposing sides of our cast malleable link firmly together by a strong
plate extending throughout a considerable part of the length of the links. This
plate may in some circumstances extend over the whole upper surface of the links,
but we prefer to confine it to the central portion.
The links are made as is usual with the male and female end, and the narrow end
between the links is connected within the wide end of the next link by a strong bolt
passing through both links. This bolt has a shoulder to enable it to be firmly
pulled up and held at a proper distance at one end. A nut and cotter or cotter
alone are arranged at one end of the bolt and a head at the other. Washers are
placed under both nut and head. A roller bush is placed between the links upon
the bolt, and this bush engages with the sprocket wells of the sprocket wheels.
The bolts may pass through bushes within the respective ends of the link, and
these bushes may be square or part of their depth square and the remainder round,
BO as to prevent any change of their rotating in the ends of the link.
The bush which is intended to engage the sprocket wells may also be arranged
on the pin, so as not to rotate. One method of obtaining this result consists in
forming the bush with square ends or with one end square and the other end part
square and part round, which square or round ends fit in corresponding apertures
in the ends of the links.

We, HENRY HACK, M.I.C.E., of the City Gas Works, Saltley, Gas Engineer,
and HENRY GILES, of Rose Cottage, Nechells Place, Saltley, Mechanical
Engineer, both in the City of Birmingham 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 :-
Our invention relates to an improved conveyor chain link, and its object is to

page_text: produce a link of simpler construction and greater durability than those hitherto
in use.
Referring to the accompanying sheet of drawings;-
Figure 1 is a side elevation of our link;
Figure 2 is a plan and,
Figure 3 a transverse section on the line x, y, of Figure 2.
In one method of carrying our invention into effect we cast the two sides A A of
the link together, connecting them by a bridge piece C passing over the top of the
links between the snugs G carrying bolts used to fasten the conveyor pans upon
the links. We thus bind the opposing sides A, A of our cast malleable link
firmly together by a strong plate extending throughout a considerable part of the
length of the links. This plate C may in some circumstances extend over
the whole upper surface of the links, but we prefer to confine it to the central
portion.
The links are made as is usual with a male and female end, and the narrow
end H between the links is connected within the wide end as I of the next link by
a strong bolt B passing through both links. This bolt has a shoulder to enable it
to be firmly pulled up and held at a proper distance at one end. A nut and cotter
or cotter B2 alone are arranged at one end of the bolt. B and a head B' at the
other. This head may be square to prevent turning. Washers may be placed
under both nut and head. A roller bush E is placed between the links upon the
bolt, and this bush engages with the sprocket wells of the sprocket wheels. The
bolts may pass through bushes within the respective ends of the link, and these
bushes such as D may be square or other figure such as hexagonal or octagonal or
part of their depth square and the remainder round, so as to prevent any change of
their rotating in the ends of the link.
The bush E which is intended to engage the sprocket wells may also be so arranged
on the pin, as not to rotate. One method of obtaining this result consists in
forming the bush with square ends or with one end square and the other end part
square and part round which square or round ends fit in corresponding apertures in
the ends of the links.
The bridge piece C may be dispensed with and the link may then be constructed
with separate sides in all other respects in accordance with the drawings.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is ;-
An improved conveyor chain link constructed and operating substantially as
hereinbefore described and illustrated in the accompanying drawings.
