PROVISIONAL SPECIFICATION.
An Apparatus for Loading and Unloading Ships, and for Conveying
Goods in Mills and Warehouses and the like.
JOHN COCHRANE Junr. 35 Lochend Road, Leith, Scotland, Plumber and
JAMES PRINGLE COCHRANE 35 Lochend Road Leith Scotland, Clerk, do hereby
declare the nature of this invention to be as follows:→
This invention relates to appliances for loading and unloading ships and for
conveying goods in mills and warehouses and consists of 2 longitudinal girders
having a revolving drum or roller running transversely at each end. The ends of
the drums are furnished with spindles which run in bushes fitted into the girders.
An endless band of stout canvas or other suitable material revolves round the
drums or rollers and extends from end to end of the girders. Friction rollers are
furnished at short distances to assist the revolving band of canvas and run in
bushes fitted in the girders. The bushes of one of the drums are fitted into slides
and furnished with a screw and eye in order to shorten or lengthen the distance
between the drums when the canvas shrinks or stretches. The drum at the
opposite end is supplied with handles for man power and with a pulley for steam
power while a brake is fitted on the spindle of the drum for regulating and
controlling the speed.
The apparatus is furnished with 2 or more adjustable trestles or bearers for
raising and lowering it to the desired height and it is also fitted with wheels fitted
to each girder to make it portable and be moved about from place to place.
The endless canvas band is supplied with ribs and studs to grip the goods and
prevent them sliding.
The apparatus works by gravitation by laying the goods on one end raised
slightly higher than the opposite one, thus allowing the endless band of canvas to
convey them down and be self acting, or the goods can be conveyed to a higher
level by the application of the man or steam power as above described.
The appliance is made in various lengths and breadths according to particular
requirements.

COMPLETE SPECIFICATION.
An Apparatus for Loading and Unloading Ships, and for Conveying
Goods in Mills and Warehouses and the like.
We, JOHN COCHRANE, Junior, Plumber, and JAMES PRINGLE COCHRANE,
Clerk, both of 35 Lochend Road, Leith, North Britain, 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 apparatus for loading and unloading ships and for
conveying goods in mills, warehouses, and other places, and consists of two
longitudinal girders having a revolving drum or roller running trausversely at each
end. The ends of the drums are furnished with spindles which run in bushes fitted
into the girders. An endless band of stout canvas or other suitable material
revolves round the drums or rollers and extends from end to end of the girders.
Friction rollers are furnished at short distances to assist the revolving band and
run in bushes fitted in the girders. The bushes of one of the drums are fitted into
slides and furnished with a screw and eye in order to shorten or lengthen the

page_text: distance between the drums when the canvas shrinks or stretches. The drum at
the opposite end is supplied with handles for hand power, and with a pulley for
steam power, while a brake is fitted on the spindle of the drum for regulating and
controlling the speed.
The apparatus is furnished with two or more adjustable trestles or bearers for
raising and lowering it to the desired height, and it is also fitted with wheels fitted
to each girder to make it portable and be moved about from place to place. The
endless canvas band is supplied with ribs and studs to grip the goods and prevent
them sliding. The apparatus works by gravitation by laying the goods on one end
raised slightly higher than the opposite one, thus allowing the endless band of
canvas to carry them down and be self acting; or the goods can be conveyed to a
higher level by the application of the hand or steam power as above described.
The apparatus is made in various lengths and breadths according to particular
requirements.
In order that our invention may be properly understood and readily carried into
effect, we have hereunto appended two explanatory sheets of drawings in the
several figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a front elevation of the apparatus.
Figure 2 is a plan of the same.
Figure 3 is a detached view of the toothed wheel and endless chain attached to
the band.
A are the two longitudinal girders, while B are the revolving drums or rollers
at each end thereof, on which the endless band C of canvas or other suitable
material is carried. D are the friction rollers which assist the revolving of the
band C. E are the handles for operating the rollers or drums B carrying the
band C on which the goods F are placed. We may also provide a pulley G, shown
in Figure 2, so that the goods may be conveyed by steam or other power in place
of hand power. L is the brake for regulating and controlling the speed, the lever l
for controlling which when not in use lies back on the side of the girder as shown
in dotted lines Figure 1. The distance between the drums is increased or
diminished by means of the adjusting screw P in the case of the canvas stretching
or shortening. The girders A rest on two or more adjustable trestles or
standards H which can be raised or lowered as may be found necessary by means
of the rack and pinion I. J are wheels fitted to the girders A, so that the
apparatus can be more easily conveyed from one place to another. K are the ribs
or studs which grip the goods to prevent them sliding. We also provide a pawl
and ratchet wheel O between girder and brake in order to keep goods at a standstill
when necessary, as shown in Figure 2.
In carrying our invention into practice the goods F are placed on the travelling
band C, and one end of the apparatus being raised slightly higher than the other,
the goods are carried down on the endless band by means of gravity; or they can
be conveyed to a higher level by haud or steam or other power as already described
and shown on the drawings.
In place of having the endless band entirely of canvas and revolving on the
rollers as described, we may have an endless chain M connected to each side of
the band, which gears into a toothed wheel N fixed to each end of the roller close
to the girders so as to prevent the cloth slipping round on the end rollers when the
goods are being conveyed to a higher level, as shown in dotted lines Figure 3.
In some cases, such for instance as loading or unloading ships the upper trestle
or standard is dispensed with, and this end of the girders would rest on the deck of
the ship.
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 :-
The general arrangement and combination of the parts of the apparatus for

page_text: loading and unloading ships and for conveying goods in mills, warehouses and other
places substantially as described and illustrated on the accompanying sheets of
drawings.
