Improvements in Butter Workers.
A communication by HANS JACOB ANDERSON and FRANK BROWN FARGO, both
of the Village of Lake Mills, in the County of Jefferson and State of
Wisconsin, United States of America, Manufacturers.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors 6 Lord Street, Liverpool and 6 Bank Street, Manchester,
both in the County of Lancaster, and 323 High Holborn in the County of
Middlesex, 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 improvements in butter workers of the class in which
the butter is worked in a revolving drum, by means of rollers between which it is
repeatedly pressed, and the buttermilk or other liquid therein is thereby eliminated
therefrom.
The invention is embodied in the novel construction and assemblage of the butter
worker and its various parts.
In the accompanying drawings
-
Figure 1 is a front elevation of the complete butter worker;
Figure 2, a central horizontal section of the drum and a top plan view of
mechanism therein and related thereto, parts being broken away to exhibit other
portions of the apparatus; and
Figure 3, a transverse vertical section centrally of a portion of the drum and
mechanism.
The frame, A, is of suitable size and form for supporting the operative
mechanism. The cylindrical drum B is closed at its rear end, and is provided
with a gudgeon C having its bearing in a suitable box therefor on the frame.
At its front end, the drum is supported and rotates on idle wheels D D, journaled
in suitable boxes therefor fixed on the frame. The drum is revolved by means of
a driving shaft E journaled in the frame, the driving shaft being provided with a
pinion splined thereon, meshing with an annular rack G on the front end of the
drum. The driving shaft is provided with fast and loose pulleys H and H¹ on
which the belt runs from the power supply. An idle bearing wheel I, mounted on
the frame, bears against the rear end of the drum at its periphery and is adapted
to hold the drum up to the pinion F.
The front end of the drum is partially closed, being closed annularly inwardly a
distance from the periphery, leaving a central circular aperture for putting the
butter into the drum and removing it therefrom. This circular opening to the
drum is further partially closed by the side boards K K, secured detachably to
the frame in the plane of the annular partial end L. These idle boards, at their
outer lateral edges, are fitted to the inner circular edge of the partial end L, and
the drum revolves around them. Buckets for elevating the butter in the drum by
its revolution are provided, consisting of the boards M M extending from one end
to the other of the drum projecting inwardly from near the periphery obliquely
to the radii, being preferably inclined forwardly inwardly in the direction of the
rotation of the drum. These buckets M, by the revolution of the drum, carry the
butter from the lower part of the drum upwardly to above the rollers N N¹, on to
which rollers the butter drops from the buckets when they have reached the top
of upward limit of their travel in the revolution of the drum. The rollers N N¹
are journaled in suitable arms therefor, projecting into the drum from the main
frame A, and are provided, at one end, with gear wheels meshing with each other,
one of which wheels meshes with the gear wheel O on the shaft E. These

page_text: rollers N N are corrugated and are arranged substantially parallel to each other
at a little distance apart in the same horizontal plane and at a right angle to the
axis of the drum. They are so arranged that they revolve in opposite directions,
inwardly downwardly, when the drum is rotated in such direction (to the right)
as to elevate the butter on the buckets.
To provide for increasing or diminishing the distance between the rollers N
and N to adapt them for better working a larger or smaller amount of butter,
the journal of the roller N' at one end is supported in an elongated bearing P, in
which it is movable from and towards the other roller, whereby the distance
between the rollers can be increased or diminished limitedly as desired, there being
sufficient play of the journal of the roller at the other end, in its bearing, for
this purpose. For conveniently moving the roller N¹ toward or from the roller N,
a rod or bar R is pivoted at its inner end on the journal of the roller N', and is
adapted to be moved endwise by the operator, thereby correspondingly moving the
end of the roller N¹. The notches S on the bar R are adapted to receive
therein a pin or catch S₁ on the frame, to lock the bar and roller in position.
Inclined boards T, secured to arms projecting from the frame into the drum,
form, with the inclined removable board T', a hopper adapted to catch and convey
the butter or any fragments thereof on to the rollers N N', as they fall from the
buckets M. A detachable inclined board U, supported on the frame below the
roller N, and projecting into the aperture in the drum, is adapted to catch and
convey into the drum any outwardly flying portions of the butter or milk as they
fall from the rollers.
For conveniently removing the butter from the drum when it has been
sufficiently worked, a detachable apron V is provided, adapted to be inserted
through the aperture in the front of the drum below the rollers N and N¹, to
the rear of the drum, for receiving thereon the butter as it falls from the rollers.
This apron V is provided with a hook or hooks W, near its edge, adapted to be
caught on to pins on the roller-supporting arms near the rear end of the drum,
whereby the apron, resting at the front end on the supports for the board U,
which has been removed for this purpose, forms an inclined way, down which the
butter readily slides out of the drum. A number of apertures Y Y, provided in
the rear end of the drum or in its periphery or both, is adapted to permit the
escape of the buttermilk from the drum as it revolves.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
•
1. In a butter worker, the combination, with a revoluble drum partially open
centrally at one end, and buckets secured to the drum on the inside about its
periphery adapted, by the revolution of the drum, to elevate butter thereon, of two
pressure rollers geared to each other, supported in the drum centrally on a suitable
frame therefor, which rollers are arranged parallel and near to each other, and a
driving shaft to which the drum and one of the rollers are directly geared
severally, substantially as described.
2. In a butter worker, the combination, with a revoluble drum partially open
centrally at one end, and buckets secured to the drum on the inside about its
periphery and adapted, by the revolution of the drum, to elevate butter thereon,
