COMPLETE SPECIFICATION filed by the said George Haseltine at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 17th September 1874, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Buildings,
London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
MACHINERY FOR RAISING OR ELEVATING COAL AND OTHER HEAVY MATERIALS," and.
have petitioned Her Majesty to grant unto me, my executors, adminis-,

page_text: trators, and assigns, Her Royal Letters Patent for the same, and have
made solemn Declaration that it has been communicated to me from
abroad by John Lemuel Bates, of the City and State of New York,
United States of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the said Invention, and in
what manner the same is to be performed, in and by the following state-
ment, reference being had to the accompanying Drawings forming a part
of this Specification.
This Invention has for its object the raising or elevating of coal or
other heavy material from the ground or out of boats into trucks or
carts, or on a conveyer, so that the material may be moved any desired
distance from the place of hoisting, and it consists,-.
First. In making the elevating channel in two parts, one sliding
within the other telescopically, so that the mouth of the channel may
be brought in contact with the material to be raised. The object of
the said Invention is to obviate the necessity of lowering the whole of
the elevator to the material, thereby saving considerable in the altitude
of the machine and in power, as the material is raised only the
necessary height.
It consists, Secondly. In so pivoting the buckets or shovels to two
endless chains, that as they come out at the lower end of the channel
they are pushed under the material before they begin to risc, imitating
as nearly as possible the motions of a shovel used by hand. The
shovels or buckets are raised in the telescopic channel by means of.
wheels and pulleys at the top of the machine, and they discharge their
loads as they pass over the discharge pulley to come down for a fresh
load. In travelling from the top of the machine to the lower end of the
elevating channel they pass under tightening pulleys, so that they are
kept taut in the channel whatever the height of the moveable part
may be.
Thirdly. In having the elevating. channel, chains, and other parts
carried by a hollow vertical column which is supported in bearings in
such a manner that the whole of the elevating mechanism may move in a
about the third of a circle, thereby allowing the mouth of the elevating

page_text: Fig. 1 is a central sectional elevation through the mme.y, y, Figure 4,
shewing the elevator as in operation; Fig. 2 is plan of the same.
Fig. 3 is a side elevation showing the clevator closed up as when not
in use, and Fig. 4 is a sectional view of the elevating telescopic channel
through the line x, x, Figures 1 and 3 drawn to an enlarged scale.
a represents the vertical column supported by the framework b, which
is erected on the boat or dock c; through the column a passes the
vertical shaft d, to the lower end of which is keyed the bevel wheel d¹,
meshing into the wheel d² fastened to the horizontal shaft d³ to which
the motive power is applied by means of the pulley d*.
At the upper end of the vertical shaft d is also secured the bevel
wheel e which operates the wheel e' secured to the horizontal shaft e³,
the said shaft e² having bearings in a forked frame f which is secured
firmly to the top of the column a. At the upper end of the frame f
bearings are provided for the two shafts g and h upon which run loosely
the drums g¹ and h¹.
: To the shaft e³ are keyed the two chain wheels i, i, which work the
two endless chains j, j, whereon the buckets or shovels k, k, are pivoted.
The upper end of the elevating channel has bearings on the shaft ġ
at either side of the drum g', and it is free to partly rotate, allowing
the lower end of the channel a motion to or from the column a, so
that the lower end of the elevating channel may be pushed into the
coal or other material to be raised as the operation proceeds, the column a
at the same time being an axis upon which the channel is allowed to
move in about one-third of a circle..
The elevating channel is made in two parts, the lower part ♬ sliding
up the outside of the upper part 7. The transverse section of the channel
is rectangular in shape with the front left open, and in the sides are

page_text: formed grooves or recesses *, *, in which the chains j,], work as shown
in Figure 4.

but
The buckets or shovels k, k, are made of sheet metal with the sides
bent up at right angles, and are shown with the back part left open,
for some purposes it would be preferable to close the back also. They
are pivotted to the two endless chains j,j, near the bottom, and the front
parts of the sides are cut in a circular form with the centre of the pivot
forming the centre of the circle; the object of cutting the sides in this
manner is to allow the pins j', j', on the chains j, j, to control the
motion of the bucket as they swing on their pivots in passing over the
various pulleys, also to hold the buckets or shovels in a horizontal
position as they travel up the elevating channel 1, l'..
Upon power being applied to the driving shaft the chain wheels i, i,
revolve and carry the endless chains j, j, with the buckets or shovels k, k,
over the various guide pulleys. As the chains j,j, leave the wheels i, i,
they pass down under the tightening pulleys m, m, which have bearings
in the frame m³, the other end of the frame m¹ being pivotted to the
casting n which is secured to the hollow vertical column a. From the
tightening pulleys m, m, the chains j, j, pass over pulleys o, o, running
on studs projecting from the frames o¹, o', which are fastened to the
channel ; as the chains j, j, with the buckets k, k, pass over the
pulleys o, o, the buckets come in contact with the piece o² fastened to
the back of the channel and are thereby turned to pass down at the
back of the channel 7 front foremost until they reach the pulleys p, p,
at the bottom of the channel where they are turned again into a
horizontal position and are pushed out under the material to be raised;
in leaving the pulleys p, p, and moving up the elevating channel they
carry up a certain quantity of the material and pass over the drum g' to
the discharging drum h¹, in passing over which they dump their
loads into the chute r. After leaving the drum ¹ they pass to the
driving chain wheels i, i, and so on. The guards is provided to prevent
the catching of the buckets k, k, in the gear wheel e¹. The chains and
buckets as they pass down at the back of the channel
from the coal or other materials by the guard sheath t.
are protected
The clevating channel is pushed out into the material to be raised,
which is represented by u, by means of two rods v, v, one end of each of
them being pivotted to the frames o', 'o', on the channel 1, the other

page_text: ends are slotted and fit over the shaft v¹ which has bearings in the
casting n; a chain v² is fastened to the shaft v¹ and the rear ends of the
rods v, v. When the shaft v¹ is turned the rods v, v, with the channel is
pushed out and held in position by a pawl on the casting n catching
into a ratchet wheel vs fast to the shaft v¹. To hold the channel ¹ down
into the coal or other substance u two rods w, w, pivoted to tho
rods v, v, at w' pass up alongside of the forked frame fand are controlled
by the pinions z fastened to the shaft z¹ which has bearings in the
frame f; the said pinions mesh into racks cut in the edge of the
rods wo, w; a pawl z prevents the turning of the pinions z, z, and keeps
the rods w, w, and the channel down. The shaft ¹ and pinions z, z,
are also used for raising the channel into the position shown in
Figure 3.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,-
First. The telescopic elevating channel 1, 1, made in two or more
parts in combination with buckets or shovels attached to endless clains,
as herein set forth and for the purposes specified.
Second. The buckets or shovels k, k, pivotted to the endless chains j,j,
in combination with the guide piece o² and pulleys p, p, substantially as
set forth and for the purposes specified.
Third. The telescopic elevating channel 1, 1, in combination with the
vertical column a, as herein set forth and for the purposes specified.
In witness whereof, I, the said George Haseltine, have hereunto
set my hand and seal, this Seventeenth day of September, in
the year of our Lord One thousand eight hundred and seventy-
