PROVISIONAL SPECIFICATION.
Improvements in and relating to Conveyors, Elevators, and
the like.
I, GILBERT LITTLE, of 3 and 4 Lime Street Square, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in conveyors, elevators, and the like.
The object of my said invention is to construct improved means whereby the
buckets, trays and push-plates of conveyors, elevators, and the like are enabled to
be readily and satisfactorily secured to an ordinary pitch-chain, which can
therefore be used therein instead of the more costly chains having specially formed
links, that have hitherto been employed in such apparatus. Moreover the said
improved means are in themselves inexpensive, and do not need any preparation.
of the said buckets, trays or push-plates other than the provision of suitable bolt-
holes therein.
According to my said invention I cast or otherwise form a bar adapted to have
the bucket, tray, or push-plate directly bolted or riveted thereto and of sufficient
length to bear at its opposite ends upon the guides of the conveyor, elevator, or the
like; midway between the ends of the bar, I form one, two, or more lugs thercon,
adapted to embrace or to enter between the links of the pitch-chain in such a
manner that they may be securely attached to the said links by a bolt or by bolts
passed through holes in the links and the lugs.
The said bar can be made of malleable cast iron, or of any other suitable material,
and the aforesaid lugs are suitably re-inforced by stiffening-webs or by other
suitable devices.

COMPLETE SPECIFICATION.
Improvements in and relating to Conveyors, Elevators, and
the like.
I, GILBERT LITTLE, of 3 and 4 Lime Street Square, in the City of London,
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:
:-
My invention relates to improvements in conveyors, elevators and the like and
has for its object to provide improved means, whereby the buckets, trays, or
push-plates of such conveyors and the like can be secured to an ordinary pitch-
chain. I am therefore enabled to use in such apparatus an ordinary pitch-chain
instead of chains having specially formed links, that have been heretofore
employed.
According to my invention I provide a bar of suitable form to which the bucket,
tray, or push-plate is bolted or rivetted. Said bar is of sufficient length to bear
at its opposite ends upon the guides of the conveyor elevator or the like and
has midway between its ends one, two, or more lugs adapted to embrace or to
enter between the links of the pitch-chain to which they are attached by a bolt
or bolts.
In the accompanying drawings.

Figure 2 is a side elevation, shewing a portion of an ordinary pitch-chain having
a bucket secured thereto according to my invention.
Figure 3 is a side elevation, and
Figure 4 is a rear view, shewing how I attach a push-plate 'in a similar manner
to an ordinary pitch-chain.
Like letters of reference denote corresponding parts in all the drawings.
A, A are two links of the pitch-chain, B is the bucket or push-plate and C is the
bar used for connecting the bucket or push-plate to the pitch chain.
In Figures 1 and 2 the bar C is shewn as being a mere flat bar of such a length
as to bear at its ends C, C upon the elevator guides and the bucket B is rivetted
on the front of the bar by rivets D. The bar has one lug C equidistant from its
ends, which fits between the two links A, A of the pitch chain and is securely
fastened in position by bolts E, E which pass through the lug and both links.
When trays or push-plates are required to be fastened to the chain the bars may
be formed with extensions or flanges to which said trays or push-plates can be
secured. For instance in Figures 3 and 4 the bar C is provided with a flange and
lugs C³ to which the push-plate B is secured by the rivets D¹, D¹. The bar in
these figures is shewn fixed on the chain in a manner similar to that above described
with reference to Figures 1 and 2.
The bars may be cast or formed in any other suitable manner and are made of
malleable cast iron or other suitable material, and the lugs formed thereon may be
re-inforced by stiffening webs or other devices if desired.
By my invention I can as hereinbefore mentioned use ordinary pitch-chains
instead of requiring chains with specially formed links which are much more
costly.
The bars which I provide are themselves inexpensive and no preparation of the
buckets, trays, or push-plates is required other than the provision of suitable bolt-
holes therein.
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
For conveyors, elevators and the like, the means substantially as herein
described, by which buckets, trays and the like are secured to an ordinary
pitch-chain.
