Improvements in Conveyors.
I, JOHN RUSCOE, of Hyde, in the County of Chester, Engineer, do hereby
declare the nature of this invention to be as follows:-
1
This invention relates to conveyors such as are used for conveying coal, coke,
grain or other materials..
In the manufacture of these conveyors whether of the pan or scraper type it has
hitherto been customary to form a chain of links of suitable construction and attach
either the conveyor pans or scrapers thereto the operative parts being this distinct
from the driving or actuating chains. This is objectionable in many ways more
especially in that a twisting strain is exerted with more or less leverage upon these
parts. This invention is designed to construct such conveyors with the operative
parts so attached or connected together as to obviate the use of the carrying chains
and to themselves take the place of the said chains thus imparting a central pull
along the whole length of the conveyor without the severe twisting strains at
present experienced.
In carrying out the invention in reference to tray or pan conveyors upon a
spindle I place or pivot two three or more brackets which are free to move
upon or rotate about the axis of the spindle and on each end of the spindle
either attached to it or free to rotate upon it I place a roller. I. prefer
at present to employ one central bracket and two side brackets on each spindle and
to these brackets the trays or pans are rivetted bolted or otherwise attached.
Between each pan or tray a similar spindle and brackets are placed and to these
the trays or pans are attached thus forming a joint or hinge between each. The
rollers and the ends of the spindles travel in slides or guides.
As applied to scraper conveyors which are constructed with a series of scrapers
working in the bottom of a trough the scrapers are formed with two wings or side
arms and with two longitudinally extending arms or links. The front and rear
arms are provided with journals or sockets to receive a spindle which passes through
and connects each pair together or the arms may be rivetted or otherwise attached
to brackets loose upon the spindle as above described. The ends of the spindles
are provided with rollers or the like to engage with the driving wheels.
Instead of sprocket wheels for driving the conveyors I employ driving wheels
with indents or recesses into which the ends of the spindles drop.
In addition to obtaining a direct longitudinal strain or pull through the operative
parts of the conveyor I am enabled by this form of scraper to convey the material
both as it advances and returns when required by employing a second channel
for the returning conveyor to work in. In such positions as no return conveyance
will be required rollers are provided at intervals to support the returning
conveyor.
The channels are provided with delivery apertures at the required intervals;
they may be erected singly or in pairs and the return may be carried either
above or below the principal conveyor.

I, JOHN RUSCOE, of Hyde, in the County of Chester, 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 :-
This invention relates to conveyors such as are used for conveying coal, coke,
grain or other materials.
In the manufacture of these conveyors it has hitherto been customary to form a
chain of links of suitable construction and attach the scrapers thereto the operative
parts being thus distinct from the driving or actuating chains. This is objectionable
in many ways more especially in that a twisting strain is exerted with more or less
leverage upon these parts. This invention is designed to construct such conveyors
with the operative parts so attached or connected together as to obviate the use of
the carrying chains and to themselves take the place of the said chains thus
imparting a central pull along the whole length of the conveyor without the severe
twisting strains at present experienced.
It will be fully described with reference to the accompanying drawings in which
as an example a coal conveyor is illustrated.
Fig. 1. Longitudinal section.
Fig. 2. Plan.
Fig. 3. Transverse section.
This conveyor is constructed with a trough A of the ordinary form in which the
scrapers B work along the bottom.
The scrapers B are formed with two wings or side arms b and with two
longitudinally extending arms or links C and D. The front arms C are each
formed with a forked journal or socket c and the rear arms each with a journal or
socket d the socket d of one scraper fitting into the forked socket c of the adjacent
one. A pin, spindle, rivet or bolt E is passed through the two sockets when
together thus connecting the scrapers B together in a long length or chain.
The scrapers B thus connected into a chain are passed over driving wheels at
each end of the trough. These driving wheels may be of any suitable shape or
construction to engage with the scrapers B but at present I prefer to make
wheels with sprockets in the ordinary way which engage with the inner end of
the fork c.
The scraper is connected into an endless chain with a second channel or other
support in the ordinary case the bottom channel would be used for conveying
material and the top one for the return empty chain but if desired the top channel
may be used for the conveyor and the bottom one for the return or they may be
used carrying a load each way.
The advantages I gain by this construction of conveyor are that I obtain a direct
longitudinal strain or pull through the operative parts of the conveyor and I am
enabled by this form of scraper to convey the material both as it advances and
returns when required by employing a second channel for the returning conveyor
to work in.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A conveyor the scrapers B of which are constructed with two side wings and
two longitudinal arms each provided with a socket by which it is connected to the

the next whereby a direct central longitudinal pulf through the scrapers is obtained
substantially as described.
3. A conveyor constructed and arranged in combination substantially as described
and shown
