Improved Apparatus for Making Up Cachets for Medical Purposes
and the like.
I, ACHILLE CHOAIN, of 43, Rue d'Idalic, Brussels, in the Kingdom of Belgium,
Pharmaceutical Chemist, 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:-
"
My invention relates to apparatus for making up cachets for medical
purposes. The principal object of my apparatus is to be enabled to make up a
considerable number of cachets of different sizes and thicknesses; the apparatus
also comprises a plate of a certain thickness, serving as a funnel for pouring
the powders into the cachets. Further, the apparatus contains a plate carrying
small cylinders hollowed out to a certain extent and fitting into each hole, and
serving for slightly compressing the powders contained in the cachets; this
compression is effected uniformly at one stroke by slightly pressing on the
upper part of this plate which is fitted externally with a flat or other spring.
This plate also serves for ejecting all the cachets at one stroke when they are
finished.
The apparatus consists essentially of four plates, namely:-
The lower plate serving to determine the thickness or depth of the cachets
and which is indicated in Figure 1 in dotted lines and marked with the letter A.
This plate, which is full and quite level, is therefore under the plate B which
receives the cachets in its holes tt; we have shown by way of example two sizes
of holes but it is obvious there can be any number of different sizes corre-
sponding to the various diameters of cachets to be made. Plate A is fitted in
its lower part with a piece C having the shape of a double T or otherwise;
this part is provided with four stops, or a larger number if desired; these
stops T are in the form of a curved flight of steps so that by shifting the knob E
more or less the support guides S fixed to the plate B are made to receive the
stops T at m, m', m (Fig.2),—according to the number of depths desired,-that
is to say, the object of this operation is to remove the plate A more or less away
from B for the purpose of obtaining cachets of different depths.
Plate I (Fig. 5) folds down on plate 1) (Figs. 3 and 4) by means of hinges H' ;
this plate is fitted with the cylinders n, n', already mentioned, and in its lower
part with some fastening arrangement V, shown by way of example in dotted
lines; in its upper part, in the middle, there is also a handle, also shown in
dotted lines.
The plate D folds down on plate B on hinges H; this plate which is of a
certain thickness and constitutes a kind of funnel arrangement, is provided
with holes corresponding to those in plate B.
These different plates are connected with each other by springs R (Fig. 3)
of any suitable kind, fixed towards the axes and, moreover, the plate I is fixed
by means of a spindle which has a certain amount of play in grooves arranged
in the hinges fixed on the plate D, for the purpose of obtaining the compression
movement already referred to.
In the accompanying drawings,—

of Figure 5.
The apparatus is worked as follows:-Seize the knob E and set it according to
the depth or thickness of the cachets to be made, take the cachets and put
them into the holes of plate B, then lower plate D down on plate B; the
margins of the cachets will then be covered up and held fixed, the central part
of the cachets only being visible; fill the cachets with the powders or sub-
stances, which should be put over the holes of plate D which serve, in a
manner, as funnels; then also lower plate I in order to compress the substances
contained in the cachets slightly and uniformly; this uniform compression is
effected by slightly pressing on the upper part of the apparatus, the upper plate I
of which oscillates by means of the springs already mentioned. This operation
having been performed, first remove plate I and then plate D), then take the
upper parts of the cachets and place them into the lower part of plate D so
that the hollow part faces the hollow part of the cachets in which the sub-
stance is contained; then slightly moisten the edges of the wafers which are
to serve for closing the cachets underneath, with water applied with a brush,
and immediately afterwards let down plate D on plate A, and all the cachets
will be sealed at one operation. Now wait a moment, to ensure good closing
of the cachets, then raise plate 1) so as to bear against plate I, and as all the
cachets are contained in plate 1) they will be expelled simultaneously by the
small cylinders of plate I. Take up all the cachets and the apparatus will
again be ready for action.
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. The hercin described apparatus for making cachets of any desired number
size and thickness; and in which the edges of the wafers can be moistened all at
once with a brush, the powder being uniformly compressed, the cachets being all
scaled up at once,
and expelled from the apparatus all at one stroke.
2. In apparatus for making cachets, an arrangement which permits adjusting
the apparatus for different depths or thicknesses of cachets to be made, and com-
prising a full, plane plate worked by a knob and which can be set at various
distances from a fixed plate.
3. In apparatus for making cachets, a plate provided with holes of different
diameters, substantially as and for the purpose set forth.
4. In apparatus for making cachets, a plate of a certain thickness also provided
with holes corresponding to those in the plate claimed in Claim 3 and serving as
a kind of funnels as well as for covering and holding down the edges of the wafers.
5. In apparatus for making cachets, a plate fitted with small hollow cylinders
of a certain height, and the diameters of which are slightly less than those of
the corresponding holes in the plate claimed in Claim 4, which serve for com-
pressing the contents and ejecting the cachets from the plate.
6. In apparatus for making cachets an arrangement of springs to ensure uniform
compression.
7. Apparatus for making cachets substantially as herein described.
