In the frame a are carried the horizontal driving shaft b and the vertical or central
shaft c as well as the small cylinder d (made of vulcanite or the like) which cylinder
is provided with a perforated lid or cover and catches in the boring e, of a plate f
resting on the frame.
By means of the bevel gearing g g' the movement of the horizontal driving shaft
is transferred to the vertical shaft on top of which an eccentric is affixed. Over
this eccentric is placed the loose shell i, which, in this present instance has nine
tooth arms, Fig. 4. In the main frame a sit the pins aº, of which, in the present
instance there are ten so that while the shaft with the eccentric makes one turn the
tooth shell has been kept back by one tooth and consequently the touching points of
pins and teeth are not always the same.
The movable disc is firmly connected with the shell i.
The shell receives through the turning of shaft c a motion which is eccentric
relatively to sbaft c, inasmuch as the centre point of the shell describes a circle round
the shaft C, and the shell receives moreover a turning motion round its own axis.
This combined motion of the shell is transferred to disc in a corresponding manner,
so that the relative motion of any point in the disc forms a series of loop like curves
round the centre of the disc.
A body lying between the fixed disc fand the movable disc k such as for instance
the substance for a pill, will therefore necessarily travel in the manner indicated and
describe a passage which is characterised thereby that the pill substance, while moving
forward in the turning direction passes from the middle towards the periphery
is then sharply turned from the periphery inwards and so on.
Fig. 5 shows this loop like road of the pill substance on plate f..
At the turning points 7 the pill quantity which has hitherto travelled-over a part
of-the curve which would tend to make a cylindrical rolled mass, is-turned-over-head
as it were and now rolled on again in this new direction, the several rapidly pro-
gressing curve formations caused by the action of discs fand k having the effect of
gradually making the pill substance take the desired ball shape, and falls ultimately
through the outlet m.
The curved line for producing the ball shape need not necessarily be just as shewn
in Fig. 5, the "loops" may be smaller or larger, broader or narrower, turn inwards or
outwards, the principal thing being the continuous alteration of direction and gradual
forward-travelling which depends upon the formation of imaginary loop.curves.

page_text: The disc k is, as explained, firmly connected with the shell i but in order to be
able to make pills of various size with the same machine the plate k must be
adjustable relatively to the plate f which adjustment is done by means of screw n
which sits in the covering disc or nave k° of plate ko, finding its support in shell i.
A gauge n° shows on a scale the adjustment of the disc in order to produce pills
of any desired diameter.
For the purpose of gradually squeezing out the pill compound serves a ramrod o,
which by means of a convenient feed contrivance presses a sufficient quantity of
pill dough out of the cylinder d for forming the pill.
The feed contrivance may as in drawing, conveniently consist of the screw or
pin o', attached to the ramrod and which is prevented from turning by means of the
guide piece o².
The feed wheel p which sits on the box o³ provided with internal screw thread receives
its movement from an eccentric p¹, by means of the eccentric rod p² and the click
lever p³. The two latter have slits in which a pin is adjustable in order to determine
the feed stroke.
The hand wheel p° serves to actuate the feed mechanism.
The feed arrangements just explained as well as the contrivance now following
are of no vital importance to the invention and may be modified in various ways.
The wheel Fig. 3 is the actuating wheel of shaft b on this latter sits as already
explained above the driving wheel g which carries an eccentric go, that moves the
aring which is affixed to the rod 9.
On the end of the pin opposite to that on which the arm q sits is fixed the cutter ",
the edge of which moves periodically over the opening d° of the press cylinder, thus
cutting off the portion of pill dough which has passed out of the opening which is
then caught by the plate k and rolled into a pill.
The flaps, turning on hinge a° serves to fasten and conveniently remove the
cylinder d.
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. A machine for making pills, in which the pills are rolled between two discs
of which one is fixed the other turnable excentrically and arranged in such a manner
that it makes a turning motion round the eccentric body in addition to the movement
round its own axis.
2. In such machines the arrangement for adjusting the distance between discs
consisting in a screw which is affixed directly or indirectly to the one disc, at the
same time being supported, directly or indirectly, by the other disc.
3. In such machines the arrangement consisting essentially in a shell surrounding
the eccentric body firmly connected with the movable disc, in connection with a
convenient contrivance for turning the shell around the eccentric body.
4. In such machines the arrangement consisting essentially of a fill cylinder
with exchangeable perforated cover through which the pill substance is squeezed being
periodically separated by means of a cutter or the like.
5. In such machines the arrangement for cutting off the pill substance escaping
through the opening in cover, consisting of an eccentric moving a bar to which the
cutter is attached..
6. In such machines the ramrod actuating mechanism consisting essentially in an
eccentric in connection with tooth wheel and lever, all substantially in the manner
as and for the purpose described.
