JULIUS A. ALEXANDER, OF SULPHUR SPRINGS, TEXAS.
IMPROVEMENT IN CHURN-MOTORS.
Specification forming part of Letters Patent No. 206,520, dated July 30, 1878; application filed
June 5, 1878.To all whom it may concern:
Be it known that I, JULIUS A. ALEXANDER
of Sulphur Springs, in the county of Hop-
kins and State of Texas, have invented cer-
tain new and useful Improvements in Churn-
Motors; and 1 do hereby declare that the fol-
lowing is a full, clear, and exact description
thereof, which will enable others skilled in the
art to which it appertains to make and use the
same, reference being had to the accompany-
ing drawings, which form a part of this speci-
fication, and in which-
Figure 1 is a front elevation; and Fig. 2 is a
top view, showing the brake and operating
mechanism.
Similar letters of reference indicate corre-
sponding parts in both the figures.
This invention relates to powers for operat-
ing churns; and consists in an improved con-
struction and arrangement of parts, having
for its object to produce a churn-motor which
may be readily regulated to roun fast or slow,
as circumstances may render desirable, sub-
stantially as hereinafter more fully described.
In the drawing, A is the motor, which is
supported upon uprights a a, above the churn
B. Thie motor A consists of a series of inter-
meshing gear-wheels and pinions, operated
by a weight, C, cord D, and drum E, in a man-
ner well understood. The weight C consists
of several parts or sections, C (' C' C , by
means of which its weight may be increased,
and the speed of the machine thereby in-
creased or decreased, at will.
F is a vertical shaft, journaled in brackets
b b, which project from the face-plate of the
motor, and has a pinion, c, keyed upon it,
which meshes with a bevel-wheel, i, operated
by the mechanism of the motor A and weight
C. To the top of shaft F is secured a hori-
zontal pulley, e, and its lower end termi-
nates in a sleeve or socket-piece, f, having a
thumb-screw, g. The dasher-staff Gis inserted-
into sleeve f and secured by the screw g, so
that it will rotate with shaft F.
H is a rod, which passes throughbearings h
Il' on the face-plate of the motor, and has a
screw-thread at one end, which works in the
screw-threaded bearing h. Its other end is
passed through a coiled spring, i, one end of
which impinges upon the bearing I', while its
other end abuts against the brake-plate k, plyiv-oted upon the end of rod H, and which pro-
jects into the motor through a slot or opening,
1, in the face-plate. m is a crank, by which
the brake-rod II may be turned and worked
forward or backward in its bearing-plates.
I is a fly-minder or fan, secured adjustably
upon the dasher-staff G- by a thumb-screw, n,
and op q are the rotating dashers, which are
secured in a similar manner upon the staff G,
so that one or more sets of dashers, each con-
structed with from one to five double blades
or wings, may be used, according to the quan-
tity of milk to be churned. The churn B is
secured in ring-brackets B' B', which are se-
cured adjustably upon an upright, K1 as shown.
From the foregoingdescription, taken in con-
nection with the drawing, the operation of my
invention will be readily understood. To set
the churn-dasher inmotion, the motor iswound
up in the same manner as an ordinary clock,
when the weight C will at once start it in mo-
tion, and its speed may be regulated either by
removing sections from or adding them to the
weight, or by adjusting the brake H k, the
plate k of which is provided with a roller,
which bears against the brake-drum of the
motor. When the brake is released by turn-
ing rod H, by means of its crank mi, the ten-
sion of the coiled spring i will immediately
release the brake-plate and roller from the
brake-drun o.
By means of the pulley e upon the top. of
shaft F, the motor may, if desired, be used to
run a sewing-machii ne or other light machinery
besides the churn.
JIaving thus described myinvention, I claim
and desire to secure by Letters Patent of the
United States-
A churn-motor consisting of the adjustable
weight C, operating-cord D, motor A, having
a brake -drum, and screw-threaded rod H, hav-
ing coiled spring i, and brake-plate k, pro-
vided with the friction-roller p, all constructed
and combined to operate substantially as and
for the purpose herein shown and specified.
In testimony that I claim the foregoing as
my own I have hereto affixed my signature in
presence of two witnesses.
JULIUS A. ALEXANDER.
