COMPLETE SPECIFICATION.
Machine for Charging Gas Retorts.
I, CHRISTIAN EITLE, of Stuttgart, 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 ascertained in and by the following
statement:-
5 This invention has for object to facilitate the charging of the retorts of gas
works, to reduce the expense thereof, and to do away with the hard manual labour
now necessary for this purpose.
In gas works the handling of the vessels for charging the retorts or the direct
shovelling in of the coal is very arduous for the workmen who are also liable to be
more or less dangerously burnt. The retorts cool owing to the slowness of the work.
They are not charged evenly consequently the bed of coal is uneven and unfavour-
able for the process of distillation, the coal chiefly at the back being frequently
drawn out without having been properly utilised.
By means of this invention the aforesaid disadvantages are removed at the same
time prolonging the life of the retorts as the machine does not come in contact with
them.
With the machine the whole of the charging operation may be easily and quickly
performed by one man.
In the accompanying drawing
Figs. 1 and 2 are respectively a side and a back elevation of the machine of this
invention.
Figs. 3 and 4 are separate views of the charging apparatus.
Fig. 5 is a sectional view of some retorts.
A is a casing in which a drum a carrying wings b rotates so as to impel the coal
supplied to it into the retort to be charged. Wings 6 first impel the coal to the back
of the retort then with the continuous supply of material, adjustment of the
height of casing A and regulating the velocity of wings small and large coal is
so delivered towards the front of the retort that in the whole length of this latter
the bed of coal is formed of perfectly equal depth which may be such as desired, it
being characteristic of the machine that the bed of coal will not exceed a height
greater than the upper surface of the outlet of casing A, all that is required being
o adjust the height of this latter according to the desired depth of charge. B is a
hopper for the reception of the charge of coal which passes thence to the end of a
evolving open spiral or worm c so that this is not pressed down with the whole weight
f the material. The spiral c winding easily through large and small coal delivers it in
roper quantity to casing A and revolving wings b. The quantity of coal periodically
elivered by spiral c is in proportion to the pitch of the same.

Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An apparatus for charging gas retorts consisting of casing A in which drum a
rotates and by means of wings & feeds coal into the retorts; spiral or worm in
immediate communication with wing drum a to the end of which spiral, coal is
supplied from hopper B and periodically delivered to wing drum a as also the
controlled differential velocities of wing drum a and spiral c produced from fly
wheel d through spur wheels f', 2, 3, 4, and bevel wheels g, g', substantially as
described and shewn.
2. In combination with the apparatus referred to in the preceding claim of the
movable frame or carriage provided with the means for raising and lowering the
said apparatus with platform D and for moving the said frame substantially as
described and shewn.
Dated this 7th day of November 1890.
