CHARLES o. DEAN, OF SHERMAN, TEXAS.
IMPROVEMENT IN ROTARY CHURNS.
Specification forming part of Letters Patent No. 1 7,521, dated February 20, 1877; application filed
September 5, 1876.To all tLwhom it may concer n:
Be it known that I, CHARLES C. DEAN, of
Sherman, in the county of Grayson and State
of Texas, have invented certain new and use-
ful Improvements in (Churns ; and I do hereby
declare that the following is a full, clear, and
exact description thereof, which will enable
others skilled in the art to which it apper-
tains to make and use the same, reference be-
being had to the accompanying drawing,
which forms a part of this specification, and
in which-
Figure 1 is a perspective view, partly in
section. Fig. 2 is a vertical section. Fig. 3
is the dasher and gear-wheel, detached; and
Fig. 4 is a plan view of the gear-wheel.
Similar letters of reference indicate corre-
sponding parts in all the figures.
This invention relates to churns; and it
consists in the arrangement, within a square
wooden box, of a rotating dasher or paddle,
and the mechanism for driving the same, the
various parts being constructed, arranged,
and operated in the manner hereinafter more
fully shown and specified.
In the drawing, A is a square wooden box,
which forms the body of my improved churn.
It has a cover, E, closely fitting, which may
be either hinged or'attached to it, when in
operation, by any suitable device. The sides
of box A, indicated in the drawing by a a,
have upon the inside dovetailed grooves b b.
In the bearings thus formed I sink a shaft,
B, which is secured in its position by slides c
a fitting in the grooves b b. Shaft B carries
the dasheror paddle-wheel C, which, as shown
in the drawing, consists simply of two per-
fotrated boards, d, crossing each other at right
angles. Shaft B also has the gear-wheel D,
which, as shown in Fig. 4, has, on its inner
surface, two grooves, e, crossing each other
at right angles. Thus, when the wheel D is
slipped upon axle or shaft B, the grooves e
will fit upon the edges of the dasher C, time
result of which is that these parts are fixed
very solidly in their relation to each other-
an object of great importance when the entire
working mechanism is made of wood, which,
in the construction of churns, is far preferable
to metal, on account of its non-liability to rust
or corrode.Between the box A and its cover E, I ar-
range, in suitable bearings f f, a shaft, F,
projecting, on one side, outside the box, where
it has a crank, G, and having, inside the
box, a drive- wheel, g, that engages with
gear-wheel D of the dasher. The cover E of
the churn must, of course, be high enough
to admit of the drive-wheel y being freely re-
volved.
The operation and advantages of my im-
proved churn will be readily understood from
the foregoing description. After pouring the
cream into box A the shaft F, with its attach-
ments, is adjusted, and the cover E is put on
and locked. The crank G is then rotated,
when the drive-wheel g, by engaging with
gear-wheel D, will rotate the dasher, which,
as before said, may be of any suitable con-
struction.
As soon as the butter is done the cover E
and shaft F are removed, when the dasher
may be easily taken out by simply removing
slides o e. The contents may now be poured
out, and the churn cleaned and put away for
future use.
It will be observed that in my improved
churn all the gearing is on the inside. This is
a feature of great importance, as, by this ar-
rangement I entirely avoid the use of lubri-
cants.
Myimproved churn ismadeof wood through-
out, anid, owing to the peculiar construction
and arrangement of its operating parts, which
have already been fully described, it is cheap,
easily operated, and cleanly.
Having thus described my invention, claim
and desire to secure by Letters Patent of the
United States-
The shaft B, having dasher or paddle-wheel
C, in combination with the wooden gear-wheel
D, having grooves e, substantially as and for
the purpose hereinbefore set forth.
In testimony that I claim the foregoing as
my own, Ihave hereto affixed my signature in
presence of two witnesses.
