Improvements in Apparatus for Stirring Thick Liquids or
Doughy Substances.
I, REINHOLD HANDEL, Manufacturer, of Leipzig, in the Kingdom of Saxony and
German Empire, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The Invention hereinafter described refers to apparatus for stirring thick liquids,
or doughy substances, and has the following advantages over the present form of like
apparatus.
First. The stirring blades can be applied and adjusted at pleasure to any suitable
kind of vessel.
Second. The dough or thick liquid can be scraped off the upper rim of the vessel.
Third. The vessel can be so connected to the apparatus that the stirring blades will
not break the vessel when in action.
A stirring apparatus according to this invention is represented in the annexed sheet
of drawings in which
Figure 1 is a side elevation, Figure 2 is an end elevation and Figure 3 is a plan of
the apparatus.
Figures 4 and 5 are details of the arms for holding the vessel.
Figure 6 is an elevation of the crosshead for carrying the stirrer arms.
Figure 7 shows the clamp device for connecting the stirrer arms to the cross-head.
Figure 8 shows a hook covered with india-rubber for holding the vessel to the
arms.
The apparatus is constructed and consists as follows:
To the vertical rod d there is attached a clamp device e by which the rod d can be
held at any height and adjusted as desired and fixed to the top of a table as shown in
Figure 1, at the upper end of the rod d there is a clamp by which there is connected
to the rod d a horizontal arm h, this arm or bracket is provided with bearings g in
which a shaft 6 runs. On one end of the shaft b there is a turning or fly wheel a and
at the other end a bevel toothed wheel c. At the end of the bracket there is a
bearing in which runs the crosshead i. The top of the crosshead is provided with a
bevel toothed wheel c¹ which gears into and is worked by the bevel wheel c on the end
of the shaft b. Attached to the cross-head i there are three arms which are formed
as shown in Figure 6, these arms are provided at the lower ends with the clamp devices k,
these clamps consist of the pieces 7, (which have on their outer side a groove) and
the clamp rings z which have a square hole n and are tightened or brought up to
the arms by the screws and nuts m. These clamp rings z receive the shafts of the
stirrers. The arms are jointed to the crosshead i so that they can be adjusted in
their spread and can, if necessary, be tightened up to the cross-head by their connecting
screws.
On the rod d between the clamps e and f there is a clamp o which can be
adjusted and which carries two arms p connected to the clamp o as shown in Figures
and 5. The vessel is held between these arms as shown in Figure 3.
When the apparatus is used, the three stirring wings or blades are placed in the
clamp rings z at the required height and are fixed by tightening up the thumb
screw m. The three stirring rings are set in such a manner that their lower ends touch
the inner surface of the vessel at different parts and then they are set in motion by the
fly_wheel a through the shaft b and the bevel wheels c, c' and the crosshead i.
The two hinged arms p attached by the clamp o to the rod d are provided to prevent
the breaking of the vessel through the continuous striking of the stirrers against the
vessel.

page_text: The vessel is held to the arms p by the hooks s, see Figures 3 and 8, owing to the
spring of the arms the vessel is kept perfectly and securely tight by placing the
clamp o lower down on the rod d.
By means of the stirrers placed at different heights all the parts of the thick mass
are brought relatively in contact with them, and consequently also with the
atmospheric air, and it is evident that the work of stirring and striking off the dough is
done much better and quicker with this machine than it could be done by hand labour.
The machine can be worked by any suitable power.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed; 1 declare that what I
claim is
1. In an apparatus of the type herein described for stirring, the arrangement herein
set forth, consisting of a cross-head i, having arms or stirrers r, that rotate with the
crosshead, said arms having a swinging or rocking movement thereon, and clamp
rings fitting in the grooved supports 1, and provided with thumb screws m, ; sub-
stantially as described and shown in the drawings.
2. In a stirring apparatus such as claimed under claim 1, the arrangement of the
rod d, with the clamp contrivance fat its upper end; the arm or bracket h, on which
the shaft is carried, provided at one end with the fly wheel a, and at the other with
the bevel wheel c, which gears into the bevel wheel c¹ on the crosshead and the
arrangement of the two clamp devices o, e one of which, the clamp o, serves to hold
the vessel containing the substance to be stirred by means of adjustable arms pp, and
the other, the clamp e, which serves to fix the apparatus to a table or other object;
substantially as described and shown in the Drawings.
