I, CARL GUSTAF PATRIK DE LAVAL, of Stockholm, in the Kingdom of Sweden,
M.A., Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to means or apparatus for driving churns by steam according
to which the churn or its shaft is provided with a worm wheel gearing with a worm
attached to a steam turbine or a steam wheel. The worm and the worm wheel are
relatively such that the churn has imparted to it the required speed.
In the annexed illustrative drawings Figs. 1 and 2 represent an arrangement of a
vertically mounted churn driven by a steam turbine the views being at right,
angles to one another and Fig. 2 being a section. Figs. 3 and 4 represent a similar
arrangement with a horizontal churn the views being likewise at right angles to one
another and Fig. 4 being a section. The same letters designate the same parts in all
the figures.
a is the stand, 6 the churn (only parts of the stand and churn are shown in Figs. 1
and 2), c the shaft or axle of the churn, d a worm wheel, e a worm in gear with the
said wheel, fa casing surrounding the worm gear, g a steam turbine, a
casing in
which the steam turbine (or the steam wheel if such be employed) revolves, i the inlet
pipe for steam passing to the turbine, k the outlet for exhaust steam, a pipe for
escape of water of condensation from the casing 4.
When using the apparatus it is only needful to open a cock in the steam pipe
so much as necessary, when steam flows into the turbine or into the wheel, thus
putting it and the worm connected with it in rotatory motion, and the worm
imparts motion to the worm wheel and thus to the churn.

page_text: I, CARL GUSTAF PATRIK DE LAVAL M.A. of Master-Samuel's-gatan 14, Stockholm,
Sweden, Civil Engineer, 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 invention relates to means or apparatus for driving churns by steam according
to which the churn or its shaft is provided with a worm-wheel gearing with a worm
attached to a steam turbine or a steam wheel. The worm and the worm-wheel are
relatively such that the churn has imparted to it the required speed.
Referring to the drawings filed with my provisional specification, Figs. 1 and 2
represent an arrangement of a vertically mounted churn, driven by a steam turbine,
the views being at right angles to one another, and fig. 2 being a section. Figs. 3
and 4 represent a similar arrangement with a horizontal churn, the views being
likewise at right angles to one another and fig. 4 being a section. The same letters
designate the same parts in all the figures.
a is the stand, b the churn, (only parts of the stand and churn are shown in figs. 1
and 2), c the shaft or axle of the churn, d a worm wheel, e a worm in gear with the
said wheel, fa casing surrounding the worm gear, ga steam turbine, ha casing in
which the steam turbine (or the steam wheel, if such be employed) revolves, i tho
inlet pipe for steam passing to the turbine, the outlet for exhaust steam, la pipe
for escape of water of condensation from the casing h.
When using the apparatus it is only needful to open a cock in the steam pipe so
much as necessary,
when steam flows into the turbine or into the wheel, thus putting
it and the worm connected with it in rotatory motion, and the worm imparts motion
to the worm wheel and thus to the churn.
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:
The combined means or apparatus for driving butter churns, consisting of a steam
turbine or a steam wheel, the shaft of which is provided with a worm, gearing with a
worm wheel on the churn or on its shaft, substantially as described.
