This Invention has for its object to provide portable and efficient apparatus or
appliances which shall be capable of raising and elevating grain or other substance
suitable for being moved by means of an endless band or chain and buckets from
one floor to another of a warehouse, from out of the hold of a ship, and for similar
purposes, where various heights of lift are required, and consists essentially in
employing in combination two or more boxes or frames, I prefer two, containing
each an endless band or chain of buckets, in connecting the said boxes or frames
together so that they shall be capable of being caused to move or slide in and out
one on the other, and in so connecting the endless bands or chains by driving gear
that when one band is driven all the others are set in motion.
The operation of the apparatus or appliances is as follows:-A box or frame
having a shoot attached is secured in any desired position, say, over the hatchway
of a ship. A second box or frame is then connected thereto at the side, and allowed
to dip into the grain or other substance it is desired to elevate. A third box or
frame may be attached to the second if desired. The endless band or chain in the
top box or frame is caused to move by means of a driving belt, say, from a steam
winch; the said endless band or chain gives motion at its lower end to a shaft and
pulley gearing into a driving, chain passing around pulleys between the two boxes
or frames. Motion is communicated from the said endless chain to the endless band
or chain of buckets in the second box or frame through a shaft and pulleys.
Motion would be communicated from the second to a third box or frame in like
manner.

The second and third or lower box or boxes are fitted with raising and lowering
gear for causing them to slide one over the other. The said gear may consist of a
block and tackle attached to any convenient securing agent. By this means the

"IMPROVEMENTS IN APPARATUS OR APPLIANCES FOR ELEVATING GRAIN, SALT,
SMALL COAL, AND THE LIKE,"
This Invention has for its object to provide portable and efficient apparatus or
appliances which shall be capable of raising and elevating grain or other substance
suitable for being moved by means of an endless band or chain and buckets from
one floor to another of a warehouse, from out of the hold of a ship, and for similar
purposes where various heights of lift are required, and consists essentially in
employing in combination two or more boxes or frames, I prefer two, containing
each an endless band or chain of buckets, in connecting the said boxes or frames
together so that they shall be capable of being caused to move or slide in and out
one on the other, and in so connecting the endless bands or chains by driving gear
that when one band is driven all the others are set in motion
The operation of the apparatus or appliances is as follows -A box or frame
having a shoot attached is secured in any desired position, say, over the hatchway
of a ship. A second box or fraine is then connected thereto at the side, and allowed
to dip into the grain or other substance- it is desired to elevate A third box or
frame may be attached to the second if desired. The endless band or chain in the
top box or frame is caused to move by means of a driving belt, say, from a steam
winch. The said endless band or chain gives motion at its lower end to a shaft
and pulley gearing into a driving chain passing around pullies between the two
boxes or frames. Motion is communicated from the said endless chain to the
endless band or chain of buckets in the second box or frame through a shaft and
pullies. Motion would be communicated from the second to a third box or frame in
fike manner.
When the endless bands or chains are in motion the lowermost band or chain and
buckets scoops up the substance or material to be raised, and elevates and delivers
it to the second band or chain, which in its turn elevates and delivers it to a third
band, or to a shoot, as desired.
The second and third or lower box or boxes are fitted with raising and lowering
gear for causing them to slide one over the other. The said gear may consist of a
block and table attached to any convenient securing agent By this means the
lower box or boxes, frame or frames may be raised and lowered at pleasure, whilst
the top box or frame remains stationary.
Figs. 1 and 2 are longitudinal views, partly in section, of apparatus or appliances
constructed under my Invention. 1 is the upper box or frame suspended by the
ring and rope 2 over the hatchway of the ship or vessel; 3 is the lower box or
frame free to slide in the guides 4, and held in position by the rope 5; the endless
chain of buckets 6 in the upper frame receives motion from the pulley 7; the
endless chain of buckets 6 gives motion to the pulley 8, which in its turn gives

page_text: motion to the endless chain 9; the endless chain 9 gives motion to the two pullies 10
on the lower box or frame 3; the pullies 10 give motion to the endless chain of
buckets 11 When in operation the grain, salt, small coal, or the like is first lifted
by the lower buckets 11, and delivered through the shoot 12 to the upper buckets 6,
which in their turn deliver through the shoot 13 on to an endless band, or as
desired.
Figs. 3 and 4 are longitudinal views, partly in section, of a further modification of
apparatus constructed under my Invention Here the upper box or frame 14 is
secured over the hatchway by the carriers 15; two lower boxes or frames 16 are
used, one on each side of the upper box or frame 14; the two lower boxes or frames
16 are attached to the sliding frame 17, which is free to move up and down the
box 14; 18, driving gear; the upright shaft 19 is geared to the horizontal shaft
and wheel 20 by the sliding wheel 21. Instead of the two lower boxes or frames 16
being on opposite sides of the upper box or frame 14 they may with advantage be
on the same side.
It will be obvious that three or more lengths of sliding frames or boxes may be
employed, and that various styles of driving gear may be used without departing
froin my Invention.
Having now described and ascertained the nature of the said Invention in such
manner that others will be enabled to carry my improvements into effect, I
claim,―
First. The improvements in apparatus or appliances for elevating grain, salt, small
coal, and the like, substantially as set forth.
Second. Employing two or more boxes or frames containing endless chains or
bands of buckets, free to slide one on the other, for the purposes set forth.
Third Driving one endless band or chain of buckets from another when such
endless bands or chains are contained in boxes or frames free to slide one on the
other.
In witness whereof, I, the said William Paulsom, have hereunto set my hand
and seal, the Twenty-seventh day of February, in the year of our Lord
One thousand eight hundred and seventy-seven.
