Improvements in Tip Wagons or Carts for Conveying Slag or other
Materials.
I, CONSTANT BOCHкOLTZ of Weilerbach near Echternacherbrück in the
German Empire, Engineer, do hereby declare the nature of this invention to be as
follows:
My invention relates to improvements in transport-carts for slags, in which the
cart can be tilted to either side; and the object of my invention is, firstly to empty
the cart when containing liquid slag by tilting slightly the platform of the cart;
secondly to empty the cart when containing solid slag by lifting the cap, and tilting
the platform of the cart as much as to cause the slag to slide down.
In order to make my invention more clear, I refer to the accompanying
drawings, in which similar letters denote similar parts throughout the different
views.
Fig. 1 is a side view of the cart, partly in section.
Fig. 2 is a front view of the frame of the cart, partly in section.
The cart consists principally of three parts; firstly of the under-frame with the
axles and wheels; secondly of the upper-frame with the platform and cap; and
thirdly of the lifting- and tilting-device, arranged between the under-frame and the
upper-frame of the cart.
Two axles 33 bearing the four wheels, support the iron-frame A forming a
rectangle. The frame A is constructed of [-iron and provided with stays, to
increase its resistance. Couplings and buffers are secured to the frame A. in the
well-known manner.
Three bearings B are attached to the frame A, supporting a shaft n; this shaft n
lies in the midst of the frame A, rectangular to the axles 3, and is provided with
three excentrics i, which support the upper frame B₁ B2 by the bearings h. The
three bearings are firmly attached to the upper frame Bi B² and they sit loosely
on the excentrics of the axle n. One of these bearings h is adapted to be coupled
with the axle n by the coupling H; and after having coupled the axle n with the
inner bearing h the upper frame B₁ B2 may be tilted by turning the axle n by means
of the cog-wheel E and screw a, arranged firmly to the axle y.
The upper frame is kept in a horizontal position by the bearings h and by four
supports c, two at every side of the under-frame; two and two supports are firmly
connected with shafts r, which are attached to the under-frame A by bearings. By
means of the shafts two supports can be moved aside at the same time. In order to
secure the upright position of the supports c they are provided with projections q,
adapted to be held by rods D; these rods are attached to a cross-piece m, having
its place at one end of the axle n.
The iron frame B¹ B² of the upper part is covered by a platform P, forming the
bottom of the cap F. The cap F is fastened to the platform P by means of projec-
tions g, pins a and wedges. The hooks 2 serve for raising the cap by means of a
crane or the like. A tap-hole w closed by a door bis arranged at one side of
the tap.
The working is the following:
The cart loaded with slag may be emptied by two different methods, according to
the liquid or solid state of the slag. Having liquid slag in the cap no considerable
inclination of the platform is necessary to empty the cap. At first the tap-hole w
is opened and the liquid slag flows out. In order to remove the residues of the
liquid slag covering the bottom of the cap, the platform P is inclined at first by
lifting it with frame B1 B2, and then tilting the platform so that it gets the position

page_text: illustrated by the line M M. The lifting of the platform is effected by the
eccentrics as before described.
Having solid slag in the cart, the cap F must be lifted at first by means of the
hooks; then the supports C are released from the rods D at one side, and by
turning the shaft r bearing these supports C the platform P hangs free at one side.
Now the platform P is easily to be tilted by hand without any effort.
In order to bring the empty platform again into its normal position the platform
with its frame B¹ B2 is coupled with the shaft n by the coupling H, then the shaft n
is turned by means of the screw-wheel E and worm ; the platform regains its
normal position which allows the supports C to be raised for the purpose of holding
the platform.
Having transported great quantities of liquid slag, the inner space of the cap
will be diminished by cooled slag; for removing that cooled solid slag the cap must
be lifted and the platform tilted as before described.
The improvements before described may be applied to all transporting cars.

COMPLETE SPECIFICATION.
Improvements in Tip Wagons or Carts for Conveying Slag or other
Materials.
I, CONSTANT BOCHкOLTZ, of Weilerbach near Echternacherbrück, in the
German Empire, Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:―
My invention relates to improvements in transport-carts for slags, in which the
cart can be tilted to either side; and the object of my invention is, firstly to
empty the cart when containing liquid slag by tilting slightly the platform of
the cart; secondly to empty the cart when containing solid slag by lifting the cap,
and tilting the platform of the cart to such an incline as will cause the slag to
slide down.
In order to make my invention more clear, I refer to the drawings sent in with
Provisional Specification, in which similar letters denote similar parts throughout
the several views and in which ;-
Fig. 1 is a side view of the cart, one half in section.
Fig. 2 is a front view of the frame of the cart, one half in section.
The cart consists principally of three parts: the under-frame with axles and
wheels, the upper-frame with the platform and cap, and finally the lifting and tilting
device, arranged between, the under and upper frame of the cart.
Two axles 33, bearing the four wheels, support the iron-frame A having the
form of a rectangle. The frame A is made of C-iron and provided with stays, to
increase its stability. Couplings and buffers are attached to the frame A in the
well-known manner.
These bearings B are bolted to the frame A, supporting a shaft n; this shaft n
lies in the midst of the frame A at right angles to the axles 3, and is provided with
three cams, which support the upper-frame B1 B2 by the plumber-block h. The
three plumber-blocks h are firmly bolted to the upper-frame B' B' and sit loosely on
the eccentrics of the shaft n. One of these plumber-blocks h is adapted to be
coupled with the axle n by the clutch H; and after having geared the axle n with
the inner bearing the upper frame B1 B2 may be tilted by turning the shaft n by
means of the worm-wheel E and endless-screw a, arranged firmly to the spindle y.
The upper frame is kept in a horizontal position by the plumber-blocks h and by

page_text: four pillars c, two on each side of the under-frame; two and two of the pillars are
firmly, connected to spindles r, which are pivoted to the under-frame A by sockets.
By means of the spindles r two pillars can be moved aside at the same time. In
order to secure the upright position of the pillars c they are provided with nozzles q,
adapted to be held by rods D; these rods are attached to a cross-piece m, mounted
at one end of the shaft n.
The iron frame B' B² supports a platform P, forming the bottom of the cart.
A removable cap F is fastened to the platform P by means of lugs g, pins a
and pegs. The hooks cast to the cap serve for raising the cap by means of a
crane or the like. A tap-hole w closed by a door bis arranged at one side of
the cap.
The working is the following:
The cart loaded with slag may be emptied by two different methods, according to
the state of the slag being either liquid or solid. If the slag be liquid no consider-
able inclination of the platform is necessary to empty the cap. At first the tap-
hole wo is opened and the liquid slag flows out, and in order to remove the residues
of the liquid slag covering the bottom of the cap, the platform is brought to an
incline by lifting it with frame B' B2, and then tilting the platform so far, that it
comes into the position illustrated by the line M M. The lifting of the platform is
effected by the cam heretofore described.
If the slag be solid, the cap F must be lifted up at first by aid of the hooks z;
then the pillars C are released from the rods D on one side, and by turning the
shaft carrying these pillars C the platform P will overhang on one half side and
the platform P may be easily tilted by hand without any effort.
In order to bring the empty cart back into its normal position the frame B¹ B2 is
coupled with the shaft n by the clutch H, then the shaft n is turned by means of
the worm-wheel E and endless screw ; the platform regains its normal position,
and again the pillars C are set upright to support the cart.
Having conveyed great quantities of liquid slag, the capacity of the cap will be
reduced by cooled down slag adhering to the sides, in order to remove these solid
pieces of slag, the cap must be lifted and the platform tilted as before described.
The improvements before described may be applied to carts of all kinds.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A tilting cart, consisting of the under frame (A) and the upper frame (B¹ B²)
both connected by the shaft (n) with cams (i) and by the supporting pillars (c) with
holders (D) and provided with a tilting device, consisting of a clutch (H), worm
wheel (E) and endless screw (a), the upper frame (B' B²) bearing the cap (F)
provided with tap-hole (w) and secured by the lugs (9) and pins (a) to the frame,
for the purpose as described.
