PROVISIONAL SPECIFICATION.
Improved Conveyors for Grain, Coal, and other materials.
1 HARRY MASON KETTELWELL 352 High Road Kilburn in the County of
Middlesex Engineer do hereby declare the nature of this invention to be as
follows:
My invention consists in making conveyors for carrying grain coal &c. with one
or more simple ropes chains or bands, part of the same being made to travel along
in a trough or channel which contains the material to be conveyed, the other or
return part of the ropes, chains or bands being carried on guide or supporting
rollers where found necessary.
In some particular cases I can make the return part of the ropes &c. to run in a
second trough or channel, thus forming another conveyor carrying in the opposite
direction.
In my conveyors, the friction between the ropes chains or bands and the material
is the means whereby the same is carried along instead of being pushed along by
scrapers or flights attached to chains &c. as is the case in the ordinary chain con-
veyors at present in use.
I use ordinary wire, hemp or other ropes, the flat belts or bands I employ are
of leather steel or other suitable material and sometimes twist that part of the
band which lies in the trough or channel, so as to prevent wear and give greater
conveying power.
The ropes, chains or bands are carried over suitable pulleys or wheels at the
ends, the same being used to transinit motion to the ropes or bands in the
ordinary way.
Where necessary I arrange tightening gear such as stretcher screws at the bearings
or weighted pulleys over which the ropes, chains, or bands pass.
The troughs are of the ordinary rectangular or half-round section and I some-
times make the bottom of same with longitudinal hollows or grooves so as to keep
the ropes chains or bands the required distance apart, & entirely empty trough.
At the end of the troughs I provide a stop plate or fork through which the

Improved Conveyors for Grain, Coal, and other materials.
I, HARRY MASON KETTELWELL, of 352 High Road, Kilburn, in the County of
Middlesex, 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 consists in making conveyors for carrying coal grain or the like
with one or more simple endless bands chains or ropes, part of the same being made
to travel along in a channel trough or the like which contains the material to be
conveyed, the other or return part of the bands chains or ropes being carried on
guides or supporting rollers where found necessary.

Fig. 1 is a longitudinal section of a metallic channel or trough.

Fig. 3, is a longitudinal section of two troughs one above the other.
Fig. 4, is a transverse section on line C D.
Fig. 5, is a transverse section of a grooved wood trough.

Fig. 7, is a longitudinal section of a grooved channel with a hinged stop plate.
Several of the figures are broken off for want of space.
Like letters refer to like parts throughout the views.
In some particular cases I can make the return part of the ropes to run in a
second trough or channel as in Fig. 3, thus forming another conveyor carrying the
material in the opposite direction.
In my conveyors the friction between the bands h ropes or chains and the
material is the means whereby the same is carried along instead of being pushed
along by scrapers or flights attached to chains or the like as is the case in the
ordinary chain conveyors at present in common use.
I use ordinary hemp, wire or other ropes , flat belting or bands h of hemp,
leather, steel or other suitable material; and I sometimes twist that part of the
band which lies in the trough or channel a as in Fig. 3, so as to prevent wear and
to give greater conveying power.
The bands chains or ropes 6 are carried over suitable pulleys or wheels e in the
centre or at the ends mounted on shafts, one or more of the same being used to
transmit motion to the ropes or bands in the ordinary way. The driving pulley d
may be fixed on either shaft at the ends of the channel a as in Figs. 1, and 2.
Where necessary I arrange lightening gear, such as stretcher screws 9 at the
bearings as in Fig. 1, or weighted pulleys over which the bands chains or ropes
pass as in Fig. 3.
The troughs with openings are of the ordinary rectangular or halfround section
and I sometimes make the bottom of same with longitudinal hollows or grooves as
in Figs. 5, 6, and 7, so as to keep the bands chains or ropes the required distance
apart and to entirely empty the trough a.
At the ends of the trough and at outlets I provide a stop platej fixed to trough
or pivoted to bearings with a lever k, or a fork through which the bands or ropes
pass so as to clean the material off same or a brush or brushes c for a similar
purpose.
If preferable the channel or trough can be made to enclose the whole of the
belts as well as pulleys and other gear at the end so preventing dust; and the
conveyor or conveyors may be fixed in an inclined position.
It will be understood that the foregoing is given by way of illustration and that
the shapes materials and parts may be varied in many ways within the scope of my
invention.
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 :-
1. In a conveyor for grain coal or the like, the combination of the channel or
trough a endless chains or ropes & pulleys e brushes c stop plate and adjustable
shaft with stretcher screws g and shaft with driving pulley and shoot f
substantially as herein described and according to Figs. 1, and 2, of the accom-
panying drawing.
2. In a conveyor for grain coal or the like, the combination of the double channel
or troughs a with openings or shoots with twisted endless flat belting running
over pulleys e with a weight, brushes c and stop plate ; for carrying the material
in the opposite direction, substantially as herein described and according to Figs. 3,
and 4, of the accompanying drawing.

page_text: 3. In a conveyor for grain coal or the like, the combination of the channel or
trough a with hollows or grooves at the bottom, and lever k stop plates and
brushes c for cleaning chains, belts or ropes, substantially as herein described and
according to Figs. 5, 6, and 7, of the accompanying drawing.
