Improvements in Squeezing and Rolling Machines.
I, EDUARD WEILER, of 23º, Englischestrasse, Charlottenburg, Berlin, in the
Empire of Germany, Manufacturer, 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 :-
This invention relates to improvements in squeezing and rolling machines
operating upon brass, iron, or steel, and has for its object to gear or drive the
former jaws positively by means of toothed segments whereby the machine is
rendered reliable in action and the material is operated upon uniformly.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a front view and Fig. 2 a side view of the machine.
Fig. 3 a plan of a former jaw.
Figs. 4 & 5 are side views of the former jaws in a closed and open position
respectively.
Figs. 6 & 7 are plans of two modified former jaws.
The construction and mode of working of the machine is as follows:-
m is the frame of the machine in which one or more pairs of former jaws a, b, of
the same or different calibre are mounted. Fig. 1 shows two pairs of former
jaws a, b, of equal calibre secured on the shafts c & d mounted in the frame of
the machine. The lower shaft d is furnished with a crank lever e which is
connected with a driving gear by means of a rod f and moved to and fro
thereby.
If motion is imparted to the shaft d and thereby to the former jaw b, by
means of the lever e, the two pairs of toothed segments 9 & h, arranged on each
side of the former jaws a & b, unroll and effect a mouth like opening and closing of
the former jaws a & b. In Fig. 1 the former jaws on the left side are shown in an
open position when the unrolling of the toothed segments 9 & h towards the back
has been accomplished, whilst on the right side the toothed segments have unrolled
towards the front and thus the former jaws completely closed.
The side view of the former jaws in these two positions, are shown enlarged in
Figs. 4 & 5, Fig. 4 showing the former jaws closed and Fig. 5 open.
g
Owing to the positive or geared movement of the former jaws through the
toothed segments & h which correspond with the form of the calibre, the material
is operated upon thoroughly uniform, an equal pressure being exerted on the
material everywhere.
It is evident that the shape of the calibre of the former jaws may be such
as deemed necessary. Figs. 1, 3, 4 & 5 show the same conical & Fig. 7 round
in shape; but they may also be formed triangular, polygonal, or otherwise.
Fig. 6 is a former jaw of conical calibre with cylindrical projection † which is
specially used for the production of carbolic acid bottles. To retain the necessary
opening in the projection free of obstruction a mandrels is provided, which
may be secured to the machine in any suitable manner, shown in dotted lines,
Fig. 6.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is-
A saucezing and rolling machine of suitable calibre characterized by driving the

page_text: former jaws (a & b) positively by means of gearing (g & h) corresponding with the
calibre of the former jaw and arranged at the sides thereof.
