French Republic, for the Invention of "IMPROVEMENTS IN THE MODE OF AND
APPARATUS FOR REMOVING CINDERS, SCORIA, CLINKERS, AND OTHER WASTE
MATERIALS FROM STEAM AND OTHER SHIPS."
COMPLETE SPECIFICATION filed by the said Gilles Louis de Maupeou
d'Ableiges at the Office of the Commissioners of Patents on the 7th August
1878.
GILLES LOUIS DE MAUPEOU D'ABLEIGES, of Cherbourg, in the French Republic.
"IMPROVEMENTS IN THE MODE OF AND APPARATUS FOR REMOVING CINDERS,
SCORIA, CLINKERS, AND OTHER WASTE MATERIALS FROM STEAM AND OTHER
SHIPS."
This Invention has for its object to provide for the removal of cinders, scoria,
clinkers, and other waste materials proceeding from boiler furnaces or other sources
on board ship, and consists,―
Firstly. In the reduction of such materials to a fluid state by their disintegration
and admixture with water, preparatory to their expulsion overboard.
And, Secondly. In the mechanical arrangements by means of which such reduction
and expulsion may be effected, and which are composed of four essential elements,
viz., a crusher or disintegrator, a mixer, an extractor, and a motor.
In the arrangement shewn in Figures 1 to 4 of the accompanying Drawings, the
crusher is composed of two rolls A, A', Fig. 3, mounted on parallel shafts and con-
nected by the gear wheels B, B¹. These rolls may be either plain, corrugated, or
to othed, according to the nature of the materials to be operated on.
T is a hopper
for the introduction of the materials which, falling between the rolls A, A¹, are
crushed by them and passed down to the receiver C, Fig. 2.
The mixing is effected by jets of water injected into the hopper T through the
orifices D, D, Fig. 3, into the receiver C, through the orifice E, Fig. 2, and into the
free space round the plunger G at the point F.

page_text: The incorporation of the materials with the water is facilitated by the screens V, X,
in the receiver C.
The extractor is composed of a pump with a plunger G, Fig. 2, provided with
caoutchouc sucking and forcing valves H, I, Fig. 2. This pump takes up the fluid
mixture from the receiver C, and delivers it into the receiver K, the upper part of
which forms an air chamber. The consistency or degree of fluidity of the mixture
is necessarily variable according to the nature of the refuse to be ejected, but as a
general rule, one part in volume of the solid materials, to, say, ten parts of water,
will be found a good working proportion.
In order to check the scoring action of the materials on the plunger G, the
packing of the latter is composed of two leathern collars F, L, separated by an
annular space through which a thin stream of water admitted at F during the
suction stroke flows round and washes the surface of the plunger. The valves H
and I are set at the lower part of the apparatus so as to secure constant washing,
and prevent the accumulation of residues at that point.
The pump is connected with the shaft of the crushing roll A by a connecting rod
of which the action is sufficiently shewn in the Drawings.
The motor consists of a steam cylinder P, Fig. 2, the piston rod of which acts
directly on the plunger, while the connecting rod O gives rotary motion to the shaft
of the crushing roll A. In order to secure due regularity in the working of the
apparatus, a fly wheel R is mounted on the shaft A¹, which runs at the highest
speed. The outer part of this fly wheel is connected frictionally with the nave so
as to relieve the strain on the shaft in case of sudden stoppage. A hammer may be
employed to break up the larger fragments of the materials before their admission
to the hopper, to facilitate their passage through the crushing rolls.
Figure 5 represents a modification of the arrangements above described, of which
it comprises the essential elements.
In this modification, the crusher A is composed of a horizontal disc, surmounted
by radial partitions, and keyed on a vertical revolving shaft B. The materials
thrown into the hopper as in T, Figs. 2, 3, fall on the disc A, in the rotation of
which they are projected and broken up against the casing of the apparatus. The
mixing is effected by jets of water admitted through the annular pipe C, C.
The extractor is composed of a centrifugal pump D, connected with the vertical
shaft of the crusher, and motion may be given to the apparatus by a simple driving
pulley, as shewn in the Drawing.
Having now described and ascertained the nature of the said improvements, and
the manner in which they are or may be carried into effect, I would have it under-
stood that I do not confine myself to the details of construction and arrangement
above laid down, as these may obviously be modified or replaced by other mecha-
nical equivalents without deviating from the principle or main features of my
Invention, but what I claim and desire to protect by Letters Patent is, the disinte-
gration and incorporation with water of cinders, scoria, clinkers, and other waste
materials derived from furnaces and other sources on board ship, and the expulsion
.therefrom of the resulting mixture, the said operations being effected by means of
disintegrating, mixing, extracting, and motive apparatus, constructed and operated,
substantially as herein set forth and shewn by the Figures of the accompanying
Drawings.
In witness whereof, I, the said Gilles Louis de Maupeou d'Ableiges, have
hereto set my hand and seal, this First day of August, in the year of our
Lord One thousand sight hundred and seventy night
