IMPROVEMENTS IN ELEVATORS AND CONVEYORS."
Year: 1880

page_text: LETTERS PATENT to John Stanhope, of Liverpool, in the County of Lancaster,
Master Mariner, for an Invention of "IMPROVEMENTS IN ELEVATORS AND
CONVEYORS."
PROVISIONAL SPECIFICATION left by the said John Stanhope at the Office
of the Commissioners of Patents on the 16th March 1880.
_JOHN STANHOPE, of Liverpool, in the County of Lancaster, Master Mariner.
"IMPROVEMENTS IN ELEVATORS AND CONVEYORS."
The said Invention relates to apparatus for elevating bulk cargo, grain, salt,
small coal, and like substances from the holds of ships or places where it is necessary
to elevate from various depths, or to various heights, and for conveying such
substances on the level or along an incline when the distance between the points
of reception and delivery varies. The objects are to construct such apparatus in a
more simple, durable and efficient manner than has heretofore been done.
The Invention consists essentially in employing an endless band or its equivalent,
either plain or fitted, formed, or provided with buckets, trays, or like appliances,
passed around pulleys or rollers moveable in pairs longitudinally, in such manner
that during one part of its length the said band or its equivalent bends back on
itself. In practice each pair of pulleys.o
or rollers is held in position in a box,
frame, or stretcher, and the said boxes, frames, or stretchers are free to be longi-
tudinally adjusted by means of screw, rack and pinion, or other suitable appliances.
Motion is given to the said endless band or its equivalent by power applied to one.
or more of the carrying pulleys or rollers. Two or more of the said elevators and
conveyers may be combined together, and they may be held or secured in position
by trestles, stanchions, standards, bolts, or in any other suitable manner.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed

The Invention consists essentially in employing an endless band or its equivalent,
either plain or fitted, formed, or provided with buckets, trays, or like appliances,
passed around pulleys, rollers, or wheels moveable in pairs longitudinally, in such
manner that during one part of its length the said band or its equivalent bends
back on itself. In practice each pair of pulleys or rollers is held in position in a
box, frame, or stretcher, and the said boxes, frames, or stretchers are free to be
longitudinally adjusted by means of screw, rack and pinion, or other suitable
appliances. Motion is given to the said endless band or its equivalent by power

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a back view; Fig. 2, a side view, and Figs. 3, 4, 5, and 6, detail views
of an elevator constructed in accordance with my Invention; A, B, are upper and
lower boxes, frames, or stretchers. The upper box, frame, or stretcher A is
provided with two pairs or sets of carrying wheels 2, 4, secured to and free to
rotate with the shafts 5, 6; 7, 8, are guide rollers or pulleys for directing the lead
of the endless chain of buckets H. The course of the buckets H is further con-
trolled by the pins 9, which move between the guide pieces 10. The lower box,
frame, or stretcher B is also provided with two pairs or sets of carrying wheels 1, 3,
secured to shafts 11, 12; 13, guide rollers. The lower box, frame, or stretcher B is
free to slide on the upper box, frame, or stretcher A, and is maintained in position
by the rope or cord 14 secured to the barrel E. The barrel E receives motion
through worm and wheel gearing 15 attached to A. in order that B may be raised
or lowered at pleasure. The box, frame, or stretcher A is held in position by the
cross bars 16 resting on the ship's decks G. The said boxes, frames, or stretchers
are preferably constructed of a metal framework filled in with wood; D, shoot
from elevator; C, chain wheel secured to the shaft carrying the wheels 4, over
which the endless chain of buckets H passes. Motion is given to the said chain
wheel, and with it to the endless chain of buckets, through a chain actuated by a
steam winch or any other suitable motive power; K, Fig. 6, shows the construction
of the wheels 1, 2, 3, and 4; F', screw shaft tunnel. Two elevators A, B, A', B¹,
are here shown connected together and driven from the same chain wheel c. It
will be obvious that only one elevator may be used, that belts or bands may be
used instead of buckets, and that the details of construction may be varied without
departing from the essential features of my Invention.
Fig. 7 is a diagram, and Fig. 8, a view partly in section of a conveyor for steep
gradients constructed under my Invention; 1, 3, 2, 4, are the pairs of wheels in
each box, frame, or stretcher; 7, guide roller; H, endless chain of buckets; A, B,
boxes, frames, or stretchers. The said boxes, frames, or stretchers are supported at

page_text: each end on any suitable carriers, and one or both of the wheels 1, 4, receives or
receive motion from any suitable power. The grain or substances to be conveyed are
fed to the endless chain of buckets from an elevator by hand or in any convenient
manner. For conveying substances in a nearly horizontal direction, bands or belts
are substituted for the endless chain of buckets.
Fig. 9 is a front view; Fig. 10, a side view, and Figs. 11, 12, and 13, are detail
views of a modification of duplex elevator and conveyor, constructed under my
Invention; A, main box, frame, or stretcher; B, sliding legs or auxiliary box, frame,
or stretcher; C, driving wheel; D, shoot; H, endless chain of buckets; 1, 3,
carrying wheels in B; 2, 4, carrying wheels in A; L, conveyor actuated through the
gearing I from the chain wheel c; F, screw shaft tunnel; 16, carrying or supporting
pieces. The same letters denote like parts to those described in the preceding
Figures.
Having now described and illustrated the said Invention, and particularized
the same in such manner that others will be enabled to carry my improvements
into effect I claim,―
First. Constructing elevators and conveyors, substantially as set forth.
Second. Constructing elevators and conveyors with endless chains, bands, or
belts led round pulleys, rollers, or wheels in moveable boxes, frames, or stretchers,
substantially as set forth.
Third. The parts A, B, H, and 1, 2, 3, 4, arranged, combined, and operating
substantially in the manner and for the purposes set forth.
In witness whereof, I, the said John Stanhope, have hereunto set my
hand and seal, this Seventh day of September, in the year of our Lord
One thousand eight hundred and eighty.
