WILLIAM GREEN HERBERT, of Liverpool, in the County of Lancaster. "IM-
PROVEMENTS IN APPARATUS FOR LOADING SHIPS AND VESSELS, PART OF WHICH
IS APPLICABLE TO OTHER PURPOSES."
The main object of my Invention is to provide simple, durable, and efficient
apparatus in part self acting for transferring from flats or lighters to ships or
navigable vessels, and loading such vessels with salt, coal, grain, or cargo suitable
for being raised or lifted in buckets, boxes, trucks, or similar receptacles; a
secondary object is to so construct buckets, boxes, trucks, or similar receptacles
used for raising materials or substances, that their contents shall be freely and
entirely discharged when required.
My Invention is carried into practice as follows:-First, a large or suitable
carrier has fitted and secured to the deck thereof a stage or platform. On the said
stage or platform is fitted a second stage or frame free to be revolved or turned
horizontally. The said upper stage is so constructed as to project over one or both
sides of the barge or carrier when in transverse position.
Second. The projecting end or projecting ends of the upper stage or frame is or
are fitted with vertical guides, on which guides, shoots, or hoppers are so fitted as to
be capable of being raised or lowered by means of screw rack or other suitable
gear.
Third. The said upper stage is fitted with a shaft or shafts driven by any suitable
power, such as a steam or hydraulic motor. The said motor is located or the power
is applied at any convenient position on the barge or carrier or on the lower or
upper stage. The connection between the power and the shaft or shafts is by
means of belting, toothed wheels, or the like.
Fourth. The shaft or shafts above mentioned are provided with a drum or
drums or pulley or pulleys, over which pass cords, ropes, or chains secured at each
end to buckets, boxes, trucks, or like receptacles.
Fifth. Buckets or receptacles generally in which materials or substances are
raised and which are intended to automatically discharge their contents are con-
structed with the back narrower than the front and with the bottom sloping

constructed with side or overlapping pieces so as to form a shoot when allowed to
fall.
Sixth. Catches and automatic opening and closing appliances are provided for
opening and closing and retaining in position the falling fronts of buckets or
receptacles employed under my Invention. The said appliances are of any well
known, usual, or desired construction.
Seventh. The buckets or receptacles are guided in their ascent and descent by
means of guide rods or their equivalent.
Eighth. Buckets or receptacles for raising or lowering materials or substances,
and which require to be guided in their ascent and descent are so guided by means
of the raising and lowering cords, ropes, or chains. Two or more such cords, ropes,
or chains, are attached to each bucket or receptacle and are led at suitable distances
apart over one, two, or more drums or pulleys.
Ninth. Shoots, endless hands, or other conveyers or elevators are used in com-
bination with apparatus under my Invention to carry away to any desired place
the contents of the buckets or receptacles after being discharged.
Tenth. To prevent the barge or carrier from being tilted or caused to lean to
one or other side when a ship is being loaded, beams, bars, girders, or steadying
pieces are secured to the barge or carrier so as to rest on the deck or take hold of
the flat or lighter from which the ship or vessel is being loaded.
