COMPLETE SPECIFICATION.
Apparatus for Charging and Discharging Gas Retorts and other
Vessels.
We THEODOR KEETMAN of Duisburg on the Rhine, in the German Empire,
Merchant, and WILHELM BACH of the same place, Engineer, do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:—
This invention relates to an apparatus for performing the several operations
required for charging gas retorts and like vessels with material-coal for instance-
which it may bring from a distance and for discharging the same and carrying the
used or exhausted material to a place of deposit.
In the accompanying drawing
Figs. 1 and 2 are respectively a back and side elevation of the apparatus.
Fig. 3 a plan of a portion thereof, and Fig. 4 a horizontal section through
line A-B of Fig. 2.
A is a metal charging and discharging scoop corresponding to the shape of the
retort for introducing the coal and removing the coke. It is carried on a vertically
movable bed or rails B fitted with roller C upon which latter one end of the
scoop rests whilst the other end rests on a slide D that may be slid along bed B for
readily moving the scoop forwards and backwards. Underneath the slide D are
two screw nuts in which work two corresponding screw rods a, a¹. By turning
these the slide D is moved forwards and backwards. is a toothed wheel fixed to
scoop A. It engages with wheel c on square shaft d. This arrangement is for
turning round or tilting the scoop A. Bed B is guided in its vertical movement
by its ends in columns E, E¹. Such movement is brought about by connecting the
said ends through plates e, e, with slides f, f', so that when these ascend or descend
so also must B. Slides f, f' have an internal screw thread and are worked up and
down by vertical screw rods g, g', driven from shaft h through bevel gearing i, i¹.
The whole apparatus is carried on wheels k and may be run on rails / by operating
bevel gearing m, m¹ through shafts
n,
n¹.
Power for working the apparatus is transmitted from a motor by means of an
endless rope, or band o, running on pullies p', p³, p³, the first for moving the whole
apparatus along the rails, the second for raising and lowering bed B and the third
for the horizontal displacement and the turning round or tilting of scoop A.
The whole apparatus is moved along rails by operating lever q thus moving
through rod q' the excentrically located shaft or bolt 92 on which rope pulley pl
with friction wheel r attached or connected thereto, turns. 1, 2 are also friction
wheels and according as lever q is moved to the right or left the one or the other
of these is pressed against by friction wheel r. Friction wheel and toothed
wheel are mounted on shaft which carries toothed wheel 5. As however
wheel is also in gear with wheel on shaft which also carries friction wheel 1.
therefore with a connection between wheels and r¹ the wheel will be turned in
a direction the reverse of that obtaining with a connection between wheels r and ²
for as wheel r drives from left to right so also does turn from left to right but
if wheel drives wheel r from left to right and wheel in the same direction
wheel will turn from right to left. Wheel drives shaft n through toothed
wheels, s, and shaft n' is thereby set in rotation through bevel gearing m and
through similar gearing m¹ turns the carrying wheels k or causes then to travel
over rails 1. Consequently according as wheel is turned in the one or the other
direction, or according as friction wheel r is placed in connection with friction
wheel or so may the whole apparatus be moved in the one or the other

page_text: direction. For raising or lowering the bed B to adjust the position of scoop A an
arrangement similar to the one described for moving the whole apparatus is
employed. By operating levert and rod t¹ in connection therewith, the friction
wheel t² may be pressed either against wheel t³ or wheel thus driving toothed
wheels u, u', and shaft in the one or the other direction. This motion is
transmitted through bevel gearing i, ¹ to the vertical screw rods g, g', to which the
slides f, f, serve as nuts. Plates e, e, connect slides f, f¹, with bed B. F is a
crane the mechanism for working it being combined with the last described
arrangement. At nearly the lowest position of bed B one of the two slides f, f¹
strikes against a bolt w fixed in between levers w¹. At the end of w¹ opposite to
that of the point of oscillation there is attached a rope or chain o'. This runs over
pullies w³ ³, w. When slides f, f₁, descend to the bottom, one of them com-
mencing from the point where it strikes against bolt w carries the rope o' along
with it to lift scoop A and bring it on to bed B.
is
The horizontal displacement of scoop A or its introduction into, and withdrawal
from retorts, and like vessels, is effected through rope pulley p³ also mounted on an
excentric bolt or spindle and with a friction wheel a fixed to or connected
therewith, which may by operating lever a² be made to engage to the left or right
with friction wheels a³, or . Each of these is cast in one piece with a toothed
wheel and respectively fixed on horizontal screw rods a, a', provided the one with a
right hand and the other with a left hand thread. According as hand lever
operated the one or the other of rods a, a', will be driven direct by friction wheel ³
or and so as by the toothed wheels to drive the screw rods in opposite directions.
As the screw nuts in which the rods work are fixed to slide D, this is moved
forwards or backwards according as the lever a³ is operated. The means for auto-
matically turning over or tilting the scoop A. consists of the square shaft d provided
at each end with a stop piece y against which the slide D strikes in both of its end
positions. In this way the square shaft d has a tendency to move in the direction
of its length, being carried along by D when this comes against either of the stop
pieces y. Upon this movement taking place the square shaft d simultaneously
turned round by the action of screw thread y' and therewith also box y² and toothed
wheel c.
Without toothed wheel no tilting takes place. When this part of the
apparatus is to be worked the lever is moved on one side so that wheels a³, x²,
are set in rotation and the scoop A thereby introduced horizontally into the retort
to remove the coke therefrom. When scoop A has quite entered the retort lever a
is reversed, reversing the travel of the scoop and bringing this backwards_hori-
zontally until it attains its former position. Lever is now disengaged and
lever operated to drive the whole apparatus on wheels k to the place for unloading
the coke in scoop A and by another disengagement and operation of lever to the
place for loading coal into the scoop when levert is operated to lower bed B in
which movement the crane rope or chain o' with scoop carrier o² is raised, the scoop
set in the same lowered, released, charged with coal, hoisted and manipulated
inversely to the discharging operation.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. In an apparatus for charging and discharging gas retorts and other vessels
the arrangement by which a scoop is operated backwards and forwards mechanically
by means of an endless rope or chain or its equivalent for the transmission of power,
and the scoop mechanically turned over or tilted at the end of the backward or
forward travel of the same substantially as described and shewn in the drawing.
2. In an apparatus of the kind referred to in the preceding claim the combination
with the arrangement for charging and discharging, of an arrangement for raising
and lowering the charging and discharging scoop consisting of a pulley mounted on
a connecting and disconnecting shaft and driven by an endless rope or chain by
which pulley the desired direction of rotation may by means of friction wheels be

page_text: given to a wheel for communicating vertical motion substantially as described and
shewn.
3. In combination with the charging and discharging mechanism referred to in
Claim 1, the arrangement for moving the whole apparatus consisting of a pulley
mounted on a connecting and disconnecting shaft and driven by an endless rope or
chain by which pulley and by means of a friction wheel in connection with the
same the one or the other of two wheels may be driven which wheels are in
connection with each other through toothed wheels or their equivalent so that the
desired direction of rotation of the shaft driven by them may be given, the said
shaft communicating through bevel gearing, movement to the supporting wheels of
the apparatus, substantially as described and shewn.
