Improvements in Machines for Producing Pastilles, Tablets,
Briquettes, and other Pressed Goods.
I, HERMANN BÖHMKEN, of Spenerstrasse 23, Berlin, in the Empire of Germany,
Merchant, 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:-
The object of the present invention is a machine for pressing pastilles or tablets,
bricks and the like out of suitable material, allowing at the same time of covering
the product in a layer of other material.
The annexed drawing represents the object of the application in a form fit
for producing pastilles or the like for use of apothecaries, confectioners, and the
like.
Fig. 1 is a front view of the machine.
Fig. 2 shows the same from the right, the fly wheel being partly broken
away.
Fig. 3 is a side view from the left, part broken away, and the work and form
table being shown in section of the linea a of Fig. 4.
Fig. 4 is a plan view of work and form table the latter being partially broken
away in order to show the recesses of the work table.
Fig. 5 is a side view of Fig. 4.
Fig. 6 is a perspective view of the form table.
Fig. 7 an under view of a part of the latter showing the displaceable valves and
the ring groove in which the same are put.
In a frame a is journalled a crank axle b, put into rotation from a fly wheel d
by means of gear c. By an eccentric e on the shaft ba press stamper 9 guided
in the frame is moved up and down. The work table is formed by a plate f
cast on frame a. This plate at the spot, lying exactly vertical under the press
stamper is provided with a perforation into which from below, a short stamper h
rises, surpassing slightly the surface of plate f and whose lower end rests directly
on the frame a. Its purpose is to discharge the plate from the stamper pressure.
On the work table rests the form table i. It is provided with a line of holes j
of exactly the same diameter as the lower end of the stamper g, and they
move exactly between the stampers g and h when the form table revolves round
the pink. The form table is provided on its circumference with as many teeth
as there are holes j. Round the pin k an arm m is moved the knee of which
goes through a slot u of the work table. In the upper part of arm m is seated
under spring pressure a dog n which gives the advancing movement to the form
table when the arm m goes to and fro. Diametrically opposite the one end
position of arin m there is arranged a pawl n' influenced by spring pressure pre-

page_text: venting the form table from following the backward movement of the arm m.
The arm m receives its movement by an eccentrically placed bolt o at the end of
the shaft and which by means of draw rods and angle levers moves the arm.
The
movable form table i has at its under side an annular groove p, lying directly
under the perforations j. In this groove hinged valves q are arranged closing the
perforations. At one place r, the stationary work table is provided with a
perforation allowing the valves q to open and let the finished pastille drop down.
In order to ensure the pushing out of the pastille, there is arranged above r
and connected with stamper g a second stamper g¹. Opposite stamper 9 there is
arranged on the work table and lying tight against it with its open lower side a
funnels serving for introducing the materials to be pressed. Beside the funnel
two powder boxes t are arranged on a common shaft, receiving a shaking move-
ment from a disk having several indentations on its circumference and moved
by means of levers and connecting rods as shown―
The working of the machine is as follows:-
The right hand powder box t drops a small quantity of powder contained therein,
into the perforation as it passes; on the passing of the perforation underneath
the funnel, it is filled with the material to be pressed and the surplus is smoothly
scraped off. The filled form goes then under the second powder box t which strews
powder on the surface. It then comes under stamper g where the pastille is
pressed, and by the next further movement it is pushed out by the stamper g¹.
Of course thé described machine in a larger size can also be used for pressing
coal-cakes, or briquettes, bricks and the like.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is
1. Mechanism for producing pressed-cakes, pastilles, and the like of any form
of more or less plastic material having a movable form or mould plate i arranged
above a stationary table f, and having its form openings near the toothed cir-
cumference of plate i and which can be brought, by means of an arm m whose
dog n is influenced by a spring, one after the other under the shaking boxes of
the funnel leaning tight on the face of the plate, and which after folding down
of the valves q lying in the ring groove of the form plate, closing their openings,
allow the press-cakes formed by means of a forming stamper g moved from the
driving shaft, to be pushed out under the influence of a second pushing out
stamper g through an opening arranged on the table f.
2. In the mechanism described in Claim 1 the arm m going in a guiding
slot u through the work table, movable round the axle k of the form plate i, in
which is arranged a dog n pushed out by a spring, and pressing against the
circumference of the form plate for pushing the latter forward intermittently
by engaging teeth on the same.
3. In the mechanism described in Claim 1 the annular groove on the underside
of the form plate t in which closing valves are arranged which are movable each
on an axle and which close the form openings j and allow in folding down in
the finished press-cakes to pass out.
4. In the mechanism described in Claim 1 one or more powder boxes t tat
the sides of the funnel above the form openings of form plate t, which are connected
with a lever operated by a tappet disk seated on the principal shaft b giving
the powder boxes a shaking movement by the revolution of the disk v.
5. In the mechanism described in Claim 1 a bolt n¹ arranged on the work
table and pushed towards the centre by a spring preventing the form plate
moved forward intermittently by dog m going backward to follow the former,
and holding the form table in the positions in which the filling of the form
openings and the formation as well as the pushing out of the pastilles takes
place.

perforation of the work table f opposite the movable stamper 9 serving as counter
seat to the movable stamper g.
