COMPLETE SPECIFICATION filed by the said Charles Wallace Hunt
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 21st November 1873, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
WALLACE HUNT, of West New Brighton, County of Richmond, State
of New York, United States of America, send greeting.

page_text: Fourthly. The peculiar construction of the counterpoise weight and
manner of hanging the same, and the connection of the same with the
wheels and pulley upon the secondary rails for the purpose of accumu-
lating a surplus force to carry back the unloaded car to its place of
loading, and of regulating and adjusting the action of the car upon
the weight so as to avoid shock and liability of injury from too much
or sudden strain.
Fifthly. To the manner of securing the end of the rope, which after
being carried in opposite directions over the pulley which operates
. the weight, raises the weight, and permits it by its fall to return
the empty car to its place of loading, and prevents any slack of the
rope...
Sixthly. The safety friction band or block upon the lower end of
the track to prevent the car from going off the rails in case of breaking.
the rope, and an adjustible friction device upon the rails when the car is
loaded for holding it securely while the loading is going on.
Seventhly. A moveable cam, to the end of which a rope is attached
so as to form an endless rope passing over pullies at either end of the
line of travel of the car to permit the dumping of the car at any point
where the cam may be fixed.
Eighthly. To the device for locking and unlocking the moveable
sides of the car, whereby the sides are locked and held fast by the
contents of the car when loaded, and are automatically unlocked by
a cam suitably arranged for the purpose, and the doors swung open
3 by the weight of the contents, and the load discharges itself.
And, Ninthly. To the peculiar construction, arrangement, and com-
bination of a track gradient with the car thereon, an endless rope
and pullies, and devices for operating the car, being a modification
of my Invention and improvement above referred to, but for the same
> object.
In the Drawings accompanying my Specifications Figure 1 is a
side elevation of my improved track, carriage, rope, and weight;
Figure 2 is a similar elevation showing some additional parts not
shown in Fig. 1, and other parts more in detail; Figure 3 is an end
elevation of Figs. 1 and 2.

page_text: are secondary parallel rails under the main track, which form a track
upon which traverse back and forth a pair of wheels d', d, and their
axle, and carrying the pulley d between them. Upon this axle of wheels
d', d', is one end of the vibrating rod or arm e, and the other end is
jointed to the weight g; this weight is constructed of a triangular shaped
frame, as shown in the Drawing, and at one angle z it is hinged to
the arme at another angle to the fixed upright beam s, and the lower
angle is filled with sufficient weight of iron or other material sufficient
to form a counterpoise to draw back the empty car after it has
descended the track and deposited its load. The rope B is connected
with the weight by carrying one end of the rope over the pulley d³,
and bringing it round under the pulley backwards and securing it
to some point at the forward end of the secondary rails d². The
other end of the upper part of the circuit of the rope after passing
round pulley 6 is passed over pulley d, and brought downwards and
backwards to the opposite or after end of the secondary track d², and
is then secured. Thus it will be seen if the rope B is put in motion
so that the upper portion of its circuit is carried towards the lower
end of the track its action upon the pulley d will necessarily draw
the wheels d', d', and the axle backwards on the secondary track in
an opposite direction, and thus by means of the arm e will raise
the weight g, and continue to raise it so long as the rope continues
its motion in the same direction. And this effect is always produced
by the operation of the loaded car descending the track by means
of the block or cam v which is set and secured upon the rope B in
such a manner and position that the cam v coming in contact with
the block in front of the car on which the rope slides, but through
which the cam v cannot pass immediately upon such contact, it takes
the movement of the car and carries with it the rope to which it
is attached, and thereby raising the weight, as above described. As
soon as the car is unloaded the weight begins to act slowly at first
and increasing in rapidity of its fall causes the empty car to move
backward towards the place of loading. The cam should be placed
at such a position upon the rope that it will not travel back as far
as the car itself travels, but will leave the car shortly before it gets
up the incline, the car then proceeding to its place of loading by
the momentum given to it by the falling weight, and the action of
the rope upon the cam v. The weight must have sufficient gravity
and length of movement to overcome the weight of the empty car

page_text: The pulley should be near the place of loading, so that the person
standing near the place of loading can readily move the rope so as to
adjust and fix the cam in at any desirable point for unlocking and
opening the sides of the car by the arm upon the car (hereafter described)
coming in contact with the cam.
Upon the track A is placed the hinged friction block 8, shown in side
view in Fig. 5, and top view in Fig. 7; the hinge is shown at 9; the loose
is forked so as not to interfere with the rope B; when the car is at its
place of loading it stands directly over the friction block, and the block
is so placed that the car slides easily over it. Under the loose end of the
block is placed an eccentric wheel 10 (Fig. 5) fast upon the shaft,
having its bearing in the sides of the track; to this shaft is attached a
crank handle by which the eccentric is turned. When the eccentric
is turned so that its larger regement is uppermost, it raises the loose end
of the friction block so that it passes against the under side of the solid
projection block fixed between the wheels of the car, and holds it while
it is receiving its load; when the car is to start the crank is turned so
that the friction block falls, and the car being released from the pressure
of the block 8 is free to move upon the track.
Figures 6 and 7 show a side and top view of a friction and safety
block (7) at the opposite extremity of the track, which the projecting
block of the car may slide and the car be thereby arrested without
shock by passing over its upper surface in the event of the car getting
loose from the rope.
In Figure 10 is shown a track which is intended to operate for the
same purposes as above set forth, but with a more simple apparatus for
operating the counterpoise weight. In this plan there is a drum u over
which the endless rope B is wound in such a manner that the movement
of the rope caused by the descent of the car winds up upon the pro-
jecting shaft t of the drum a rope e¹ to which is suspended the weight g¹.
The operation of this plan is obvious without further description.
The car W (Figs. 1, 2, 3,) is constructed with a bottom of two fixed
equal sides rising to a pretty sharp angle at their intersection as seen
in Fig. 3.
The sides of the car are composed of two parts, one fixed, the other
movable. The lower half of the sides of the car swing outwards when
discharging the load, and inwards when the car. is to be. loaded, being

page_text: hung by suitable hinges to the upper fixed part of the sides of the car.
Along one of the swinging leaves near its lower outer edge is placed the
vibrating rod 1 (Figs. 3) which is held by and turns in eyes of bolts
fixed in the swinging leaf. The ends of this rod 1 are extended beyond
the ends of the car each way, and their projecting ends 3, 3, are bent at
nearly right angles to the rod, and have at their ends cycs or rings.
Upon the opposite swinging leaf of the car towards the lower outer edge
at the corners are two bolts having eyes or rings in their projecting
heads. Fastened to the eyes of 3, 3, and through the eyes of the bolts
in the opposite leaf a rope or chain 2 is passed, the rope passing entirely
around the car. The ends of the rope are fastened to the arms 3, 3, so
that the swinging leaves or doors are when closed made fast to each
other and not to the car by this rope. Upon the rod is fixed the
vibrating arm C, in such a manner that when the arm c is downwards
the rope will be always strained so as to draw together and hold closed
the swinging leaves of the car by means of the projecting arms or
cranks 3, 3, to which the rope 2 is fastened, and which cannot turn
downwards by reason of the arm C pressing against the side of the leaf,
but when the end of the arm C comes in contact with the cam in the
arm C is pushed upwards and outwards whereby the arms or cranks 3, 3,
are turned upwards, and the rope 2 being thus released from the strain
also releases the leaves, and the pressure of the load opens the doors and
the load is immediately discharged by its gravity. The cranks being
then turned downward to the position for closing the leaves the car is
again ready for its load.

fall, and its descent by means of the rope B automatically draws and
sends the car back to the place of loading, when swinging sides of the
car being again closed it is again loaded and the operation thus
continuously carried on.
The modification of my Invention and apparatus herein-above referred
to, as represented in Figures 11 and 12 in the Drawings is constructed,
arranged, and operated as follows:-The track is shown at A, A,
supported upon trestles a, a. The inclination of the track is gentle at
the beginning where the load is taken, and gradually takes a more rapid
descent until it approaches the place of discharge, where the track is
upon a straight level or nearly so, a continuous or endless rope B, is
carried from one end of the track to the other, and passes round the
grooved pulley 6 at the place of loading, and the grooved pulley c at tho
place of discharge, which pullies are upon axles having their bearings in
the tracks. This rope B has its two ends connected and fast to the
opposite ends of the link d. Upon this link is a running grooved
roller d', which is supported by and rolls upon the grooved strip or
offset d upon the side of the intermediate horizontal rail A². The link
d has a straight projecting arm fixed to it, which passes and slides along
and against the side of the intermediate rail, and prevents the roller d'
from coming out of the groove or way made by the grooved strip d².
The rope also slides over this grooved way.
.
The roller is so arranged and connected with the counterpoise
weight hereafter described, that when the weight is at rest and at its
lower point of descent, the roller is in the same vertical line with the
weight. To the link dis hinged the lifting rod, or rope, or chain e, and
at its lower end is suitably secured to the vibrating bar f, upon which
the weight g is adjusted, at the lower end of the vibrating bar is hinged
to a bearing firmly fixed in ground. The rope B passes under the car or
wagon, and slides through a block or guide h secured to the forward end
of the car. Upon the rope B is placed the block or cam i, and by means
of a slot in the side of the cam, and a ferule k upon its tapered end, it is
made adjustiable upon the rope, and capable of being fixed at any desired
part of the rope. This block or cam i must be placed upon such part of
the rope B that the loaded car in descending the track will come in
contact with the cam, so as to set the rope B in motion at such a point
