PROVISIONAL SPECIFICATION.
Improvements in Conveyors and Elevators and their Parts.
I, CHARLES HUNT, of Windsor Street Gas Works, Birmingham, in the County
of Warwick, Civil Engineer, do hereby declare the nature of my said invention to
be as follows:-
My invention has for its object improvements in conveyors and elevators and their
parts and is for the purpose of simplifying their construction so as to reduce
friction and minimize the weight of the parts and further to provide for the rapid
and cheap exchange of those parts which are the most liable to rapid wear as also
for such wear.
This is especially necessary for conveyors and elevators used for
the transmission of coke or its refuse as the constant grinding and friction is excessive
but my invention will likewise be applicable to the transmission of coal or other
matter.
My conveyor or elevator buckets are so constructed as to require no lateral
assistance as regards their strength and whenever it is practicable to do so, having
regard to the other parts, I cast or otherwise form parts or portions of the links
upon the back of the buckets conveyor plates or pans, or in other words construct
the buckets conveyor plates or pans so as to form links of the chain itself or
projections may be cast upon certain of the links to mount into corresponding
recesses in the back of the buckets or conveyor plates or pans rivets or bolts
passing through to secure them together thus ensuring accuracy and firmness. The
front of the buckets when used as elevators are so formed at each end with recesses
as to receive removable fronts which may be exchanged from time to time when
considerably worn and the exposed edge of such exchangeable part may be
specially cast or formed to withstand the rubbing action. The chain is formed
from malleable cast or other suitable metal and the eyes of the links are so designed
us to form sockets and journals upon which all the strain and wear takes place,
the bolts or pins passing through them merely holding the parts together. These
links are formed with a plate connecting the two bosses and a feather or plate
rising from the same to stiffen the parts and the links may be made with two
sockets or two spigots or with one socket and one spigot and this equally applies to
the bucket when the bucket is so mounted as to form a link in the chain. The parts
may be so brought together that the sprocket wheels carry the weight of the
buckets near each side of their centres or the links may project at each end of the
buckets in urder that the buckets 'may be so.designed und shaped as to fall between
the sprocket wheels which enables them to act as conveyors as well as clevators but
in the latter case the buckets have to be designed to carry the whole lateral weight
of tlie lond which will often be found to be the most economical mode of construction
and the steadiest in practise. In mounting the apparatus whether for conveyors
or elevators a simple mode is to fix one girder or beam upon which the axles of the
spocket wheels are mounted the wheels working upon the ends of the axle on each
side the beam and project sufficiently above it to allow the specially formed buckets
to lie between them without reaching the beam.

I, CHARLES HUNT, of Windsor Street Gas Works, Birmingham, in the County
of Warwick, Civil Engineer, do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My 'invention has for its object improvements in conveyors and elevators and
their parts and is for the purpose of simplifying their construction so as to reduce
wear and tear and minimize the weight of the parts and further to provide for the
rapid and cheap exchange of those parts which are the most liable to rapid wear as
also for such wear. This is especially necessary for.conveyore and elevators used
for the transmission.of coke or its refuse as the constant grinding and friction is
excessive but my 'invention will likewise be applicable to the transmission of coal.or
other matter.
"
My conveyor or elevator buckets are so constructed as to require no latteral
assistance as regards their strength and whenever it is practicable to do so having
regard to the other parts I cast or otherwise form parts or portions of the links
upon the back of the buckets conveyor plates or pans or in other words so construct
the buckets or conveyor plates or parts so as to form links of the chain itself or
projections may be cast upon certain of the links to mount into corresponding
recesses in the back of the buckets or conveyor plates or pans rivets or bolts
passing through to secure them together thus ensuring accuracy and firmness. The
front of the 'buckets when used as elevators are so formed at each end with recesses
so as to receive removable fronts which may be exchanged from time to time when
considerably worn and the exposed edge of such exchangeable part may be
specially cast or formed to withstand the rubbing action. The chain is formed
from malleable cast or other suitable metal and the eyes of the links are SO
designed' as to form sockets and journals upon which all the strain and wear
takes place the bolts or pins passing through them merely holding the parts
together. These liuks are formed with a plate connecting the two bosses and a
feather or plate rising from the same to stiffen the parts and the links may be made
with two sockets or two spiggots or with one socket and one spiggot and this
equally applies to the bucket when the bucket is so mounted as to form a link in
the chain. The parts may be so brought together that the sprocket wheels carry
the weight of the buckets near each side of their centres or the links may project
at each end of the buckets in order that the buckets may be so designed and shaped
as to fall between the sprocket wheels which enables them to act as conveyors as
well as elevators but in the latter case the buckets have to be designed' to carry the
whole latteral weight of the load which will often be found to be the most
economical mode of construction and the steadiest in practice. In mounting the
apparatus whether for conveyors or elevators a simple mode is to fix one girder or
beam upon which the axles of the sprocket wheels are mounted the wheels working
upon the ends of the axle on each side the beam and projecting sufficiently above
it to allow the specially formed buckets to lie between them without reaching the
heam.
In order that my invention may be clearly understood and be more easily carried
into practical effect I have appended hereunto two double sized sheets of drawings
upon which my invention is illustrated with exainples of its application which will
enable others to apply it to other cases met with in practice.
Figure 1 is a side elevation showing my invention applied for elevating coke or
other matter from the recesses or pit P and showing the sprocket wheel W
supported by the axle X on the centre beau Y..
Figure 2. is a front elevation of the unner ortion of Figure 1.

page_text: Figure 3 is a back elevation of a bucket having a link A formed upon´it që oast
with it thus making the bucket itself one of the links.
Figure 4 is an end elevation and section of Figure 3.on the line 12 of Figure 5
and looking to the right.
:
Figure 5 is a sectional plan of the bucket B shown by Figure 3.
Figure 6 is a part section and part side elevation of two of the links A brought
together in working condition.
די
Figure 7 is a plan of the two links A shown-by the previous Figure 6.
Figure 8 is a side elevation showing a very simple and cheap construction of
elevator with the buckets forming two links connected at each end by links A.
Figure 9 is a front elevation of the buckets and links shown by Figure 8.
Figures 10 are side view and cross section of the sprocket wheel.
Figures 1 and 2 show an elevator with buckets B attached thereto each bucket
having two links similar to A' attached to it by peans of rivets or bolts passed
through the holes a, a, and corresponding holes in the buckets. The connecting
links A of which there may be any required number between each bucket, are
formed with a journal a at one end and a socket a³ at the other end as shown in
the larger details of Figures 6 and 7 where two links are shown brought together.
The pin portion a³ enters a³ and forms the joint so that all the wear and strain is
taken up by the links themselves, the pin a' only requiring to keep the parts
together by means of the split pin as or other equivalent modes such as bolts well
known. These links are generally made from cast metal but they may be stamped
or otherwise forged. It will be noticed in the instance shown that the link A' only
differs from A in having its web a prolonged sufficiently to carry the holes a for
connection to the bucket B or to the conveyor as the case may be only in the case
of conveyors they would be designed to suit their flat position and the matter to be
conveyed. The links A' may however be cast or formed upon the buckets B
either at the end or a double or single one at or near the centre as shown by
Figures 3 4, and 5. On the other hand a very simple elevator may be constructed
by forming projections on each side of the buckets B as illustrated by Figures 8
and 9 when it is only necessary to pass over the links A with-in this case-their
double sockets that is a socket a³ at each end, when the whole are seamed together
by a pin passing right through the buckets and studs and links or short bolts or
pins may be used, but even in this case the wear and strain is not upou the pin or
bolts. Even in the case of these Figures 8 and 9 there may be any number of
intermediate links A used so as to make the buckets or conveyors any pitch. The
sprocket wheels W and W have hollows w' into which the sockets a of the links
take thus avoiding unduely sharp teeth which are liable sometimes to foul.
spocket wheel W is shown in clear detail at Figures 10. Where much wear has to
be provided for in buckets B1 form them so as to receive a renewable front b
which is bolted rivetted or otherwise fastened by such like flanges as 6' and rivets b³.
These renewable fronts may only continue a part of the distance down or at the
lip and they may be thicker and harder at that portion so as to better withstand
the rubbing and wear. In the example of the elevator shown by Figures 1, and 2
either the wheel W' or W2 may be then driven but I make no claim to the mode of
driving. It will be evident that the webs and other parts of the links A may be
formed to any sections and configuration to serve any particular purpose for which
they may be required. In the case of conveyors the receptacles may be made from
flat or dished plates with side flanges only or both side and end flanges and these
may be secured to the links such as A' or links may be cast or formed on their
ends or underneath and it will be evident that such receptacles or troughs or
carriers would be designed to suit the matter to be conveyed.
