Stevedore, for the Invention of "IMPROVEMENTS IN AND CONNECTED WITH
APPARATUS OR APPLIANCES FOR ELEVATING AND TRANSPORTING GRAIN, SALT,
SMALL COAL, AND THE LIKE"
Sealed the 5th March 1880, in pursuance of an Order of the Lord Chancellor, and,
dated the 2nd September 1879.

PROVISIONAL SPECIFICATION left by the said William Poulsom at the
"
the Office of the Commissioners of Patents on the 2nd September 1879..
WILLIAM POULSON, of Liverpool, in the County of Lancaster, Stevedore.
IMPROVEMENTS IN AND CONNECTED WITH APPARATUS OR APPLIANCES FOR
ELEVATING AND TRANSPORTING GRAIN, SALT, SMALL COAL, AND THE LIKE."
The said Invention relates more especially to apparatus or appliances for which
I obtained Her Majesty's British Letters Patent, No. 3429, of the year, 1876, and
has for its main object to render the action of such apparatus or appliances more
effecient and trustworthy in their operation. Parts of the said Invention are also
applicable to elevators of any ordinary or desired construction.
First. To obtain an elevator which shall have lightness and strength so combined
that such elevator shall be capable of being easily moved from place to place, and
yet possess sufficient rigidity to prevent flexure or disarrangement of the parts
whilst being handled. I construct the said elevator of angle iron framework
combined with wood to form the sides, and I connect the elevator buckets to
peculiarly constructed chains (hereinafter described).
Second. To enable the elevator buckets and chains to be cheaply and lightly
constructed and to facilitate repairs I make use of a chain, each link of which is
constructed with a hook in such manner that the chain is made up of links hooked
together. The links are made both plain and with projections or pieces, to which
the buckets are attached. The buckets are constructed of thin sheet metal, and
are fitted at each side with one or more pins or bearings which fit in or on the
projections or pieces on the links above mentioned. The above construction of
parts allows of buckets being placed any desired distance apart, and also permits of
the easy removal and repair of any damaged portion.

page_text: Third. To allow of elevators being made to occupy small space, and to ensure
that the contents of the buckets shall be deposited at the desired times, I fit such
buckets with projecting rollers or pins which take into grooves formed in the frame-
work of the elevator, such rollers or pins and grooves serving to guide the buckets
in their descent and ascent and to give the requisite tipping motion when necessary.
By the above means I am enabled to freely discharge buckets when the elevator is
in a perpendicular position, or leaning slightly in the opposite direction to that in
which the discharge takes place, and I am further enabled to make the said
elevators to occupy much less space by leading back the grooves after they have
passed around the wheel or wheels at the top.
Fourth. To ensure that the grain or substance being elevated shall be discharged
into the receptacle at the top of the elevator, when such elevators are used on board
ship, I fix the buckets on the interior of the chain and place the discharge shoot in
the centre of the elevator close beneath the said chain at the top.
Fifth. I employ elevators constructed as above described in combination, sub-
stantially as set forth in Her Majesty's British Letters Patent, No. 3429 of the
year 1876, granted to me.
Sixth. When the elevators are used in combination, as mentioned under the
above fifth head, I fit the upper elevator with a drum and cords or chains, which
are attached to the framework carrying the lower elevator or elevators, and I give
motion to such drum preferably by means of a worm wheel and, screw, so that the
lower elevators may be raised and lowered at pleasure.. The said lower elevators
discharge into a shoot within the upper elevator..
Seventh. I carry the discharged grain or material away from elevators by means
of travelling chains, fitted with trays or bags of canvas or like material, and I so
connect such travelling chains and their carrying framework to each other by
means of bevel wheels, straps, links, or other means, that the said travelling chains
and their framework may be raised, lowered, and placed at any desired angle, and
lengthened or shortened at pleasure.
The chains herein mentioned are continuous and work around pulleys or wheels,
which latter are driven by power in any convenient manner.
Eighth. In order to be able to easily bring the grain or material from various
points to the bottom of the elevator I gear an endless chain or band to one of the
totating wheels of the elevator, and employ such endless chain or band to give
motion to scrapers or equivalent devices.
The said elevators may be applied over the hatchway of ships or vessels and
receive motion from a steam winch, or they may be permanently attached to a flat
or lighter, or adapted to a travelling carriage or truck, or they may be fitted in
warehouses, on quays, or other suitable places.

" IMPROVEMENTS IN AND CONNECTED WITH APPARATUS OR APPLIANCES FOR
ELEVATING AND TRANSPORTING GRAIN, SALT, SMALL, COAL; AND, THE LIKE."
The said Invention relates more especially to apparatus or appliances for which
I obtained Her Majesty's British Letters Patent, No. 3429 of the year 1876, and³
has for its main object to render the action of such apparatus or. appliances more
effecient and trustworthy in their operation. Parts of the said Invention are also
applicable to elevators of any ordinary or desired construction.
First. To obtain an elevator which shall have lightness and strength so combined
that such elevator shall be capable of being easily moved from place to place, and
yet possess sufficient rigidity to prevent flexure or disarrangement of the parts
whilst being handled. I construct the said elevator of angle iron framework
combined with wood to form the sides, and. I connect the elevator buckets to'
peculiarly constructed chains (hereinafter described).
.).
Second. To enable, the elevator buckets and chains to be, cheaply and lightly
constructed and to facilitate repairs I make 'use of a chain, each link of which is
constructed with a hook in such manner that the chain is made of up of links hooked
together. The links are made both plain and with projections or pieces, to which
the buckets are attached. The buckets are costructed of thin sheet metal, and are
fitted at each side with one or more 'pins or bearings which fit in or on the pro-
jections or pieces on the links above mentioned. The above construction of parts
allows of buckets being placed any desired distance apart, and also permits of the
easy removal and repair of any damaged portion.
..
Third. To allow of elevators. being made to occupy, small space, and to ensure
that the contents of the buckets shall be deposited at the desired times, I fit, such
buckets with projecting rollers. or pins which take into grooves formed in the
framework of the elevator, such rollers or pins and grooves serving to guide the
buckets in their descent and ascent, and to give the requisite tipping motion when
necessary. By the above means I am enabled to freely discharge buckets when the
elevator is in a perpendicular position, or leaning slightly in the opposite direction
to that in which the discharge. takes place, and I am further enabled to make the
said elevators to occupy much less space by leading back the grooves after they
have passed around the wheel or wheels at the top.
Fourth. To ensure that the grain or substance being elevated shall be discharged
into the receptacle at the top of the elevator, when such elevators are used on board
ship, I fix the buckets on the interior of the chain and place the discharge shoot in
the centre of the elevator close beneath the said chain at the top.
Fifth. I employ elevators constructed as above described in combination, sub-
stantially as set forth in Her Majesty's British Letters Patent, No. 3429 of the
year 1876, granted to me.
Sixth. When the elevators are used in combination, as mentioned under the
above fifth head, I fit the upper elevator with a drum and cords or chains, which
are attached to the framework carrying the lower elevator or elevators, and I give
motion to such drum preferably by means of a worm wheel and screw, so that the
lower elevators may be raised and lowered at pleasure. The said lower elevators
discharge into a shoot within the upper elevator.
Seventh. I carry the discharged grain or material away from elevators by means
of travelling chains, fitted with trays or bags of canvas or like material, and I so

page_text: connect such travelling chains and their carrying framework to each other by
means of bevel wheels, straps, links, or other means, that the said travelling chains
and their framework may be raised, lowered, and placed at any desired angle, and
lengthened or shortened at pleasure.
The chains-herein mentioned are continuous and work around pulleys or wheels,
which latter are driven by power in any convenient manner.
Eighth. In order to be able to easily bring the grain or material from various
points to the bottom of the elevator I gear an endless chain or band to one of the
rotating wheels of the elevator, and employ such endless chain or band to give
motion to scrapers or equivalent devices.
The said elevators may be applied over the hatchway of ships or vessels, and
receive motion from a steam winch, or they may be permanently attached to a flat
or lighter, or adapted to a travelling carriage or truck, or they may be fitted in
warehouses, on quays, or other suitable places.
Fig. 1 is a side elevation, partly in section, of apparatus or appliances illustrative
of the eight heads of my Invention.
First & Second Heads. a, angle iron framework; b, wood sides; c, chain con-
structed of links, hooked together by the hooks c¹; c², projecting pieces formed
with the links, to which the thin sheet metal buckets & are attached by the pins c,
see Fig. 2.
Third Head. The buckets & are fitted with rollers f, which take into grooves g
in the framework of the elevator. The said grooves g are caused to curve round
the wheel, carrying the chain as shown at gl, so as to obtain a good angle for
tipping, and at the same time allow of the elevator being made as narrow and
compact as possible.
Fourth Head, see Section Fig. 3. The buckets & are secured on the interior of
the chain c, and the shoot i into which they discharge is placed in the centre of
the elevator close beneath the top carrying wheels j. The grooves g are here made
double, so as to obtain a proper motion of the buckets at the top. The said buckets
are pivoted to the chains, and are held in perpendicular or other position by the
means of the rollers f moving in the said grooves g.
Fifth Head. The elevator / is combined with the elevators 7, substantially in the
manner set forth in Her Majesty's British Letters Patent, No. 3429 of the year
1876, granted to me.
