An Improved Butter Worker.
I, WILLIAM WILSON HORN, of the Firm of Horn & Son, of 151 Strand, London,
Middlesex, Patent Agent, do hereby declare the nature of this invention, (a
communication to me from abroad, by Alma A. Foster, of Pomeroy, Ohio, United
States of America, Inventor,) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This my invention relates to an improved machine for working butter, and has for
its object to provide a machine of simple and durable construction, in which the
butter as taken from the churn may be placed and its position automatically shifted
while rolling pressure is brought to bear thereon.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar letters and figures of reference indicate corresponding
parts in all the views.
Figure 1 is a plan view of the machine. Figuro 2 is a front elevation of the
machine having the front flange of the trough cut away. Figure 3 is a central
vertical section through the machine. Figure 4 is a side elevation of the gearing
detached; and Figure 5 is a partial side elevation of the frame and trough, the latter
being shown in position thereon in positive lines and as lifted off in dotted lines.
The frame of the machine consists, essentially, of four or more uprights 10,
connected at the top, with the exception of the front, by horizontal cross-bars 11, and
near the bottom at each side by rearwardly-inclined side bars 12, which side bars
project beyond the front, and are in turn connected by a cross-bar 13 at the pro-
jecting ends and a second cross-bar 14 at the rear of the forward uprights. Upon
TD011

page_text: the inclined side bars of the frame trough adapted to receive the butter is supported.
This trough is essentially triangular in general contour, being curved at the outer or
wider end, and straight at the inner or contracted end. The trough consists of a
bottom 15, having vertical side and front flanges 16 and 17, and also a rear flange 18.
In the rear flange 18, at or near the centre, a suitable aperture is made, in which a
faucet 19 is introduced, and between the centre and the rear end flange of the trough
a curved transverse partition 20 is secured concentric with the front flange, in which
partition a series of vertical slots or openings 21 is produced to permit any liquid
placed in the trough with the butter or extracted from the latter to pass out into tho
compartment A at the rear of the trough, from whence it may be drawn through the
faucet 19. The rear flange 18 is preferably made of greater depth than the front
flange 17, and the sides 10 are preferably of such depth that when in the frame their
upper edges will be on a level, in order that the trough may be filled with water
when so desired. The forward compartment B of the trough is provided at the centre
with a longitudinal rigidly-attached strip 22, forming a portion of the auxiliary or
working floor, the sides of which central strip of the auxiliary floor are inclined from
the front in the direction of the rear, whereby the inner end of the strip is narrower
than the outer end, and to each side of the central strip 22 corresponding strips 23
and 24 are respectively hinged, which side strips 23 and 24 virtually constitute
wings, and are each adapted at times to maintain a perpendicular or essentially
perpendicular position as shown in Figure 2.
The outer side of each of the wings 23 and 24 is provided with an upwardly-
inclined flange 25, to the outer face of which flanges, at or near the centre, a bracket-
arm 26 is rigidly secured by bolts, staples, or otherwise, for a purposo hereinafter
stated.
The bracket-arms may be fitted in suitable recesses produced in the outer face of
the wing-flanges 25, or the side-flanges 16 of the trough may be recessed to receive
them in which latter event the brackets are simply attached to the outer face of the
wing-flanges. The hinges employed are preferably of such a nature that when the
wings are elevated to the perpendicular position there will be no visible space
between the contiguous edges of the wings and the centro strip of the working-
floor.
The working-floor, it will be understood, includes the central strips and the wings
and essentially fills the entire space within the forward chamber B of the trough.
The forward edges of the wings, and likewise the rear edges are preferably metal
bound, as shown at 27 in Figure 2.
It will be observed that as the supports 12 of the trough are inclined when the
trough is placed in position thereon it will be inclined also from the front to the rear.
In order that the trough when placed upon the supports may not slip under the
action of the roller, hereinafter described, cleats 28 are placed upon the cross-bars 14.
near each end, which cleats have bevelled inner ends to fit snugly against the inclined
sides of the trough, and similar cleats 29 are placed upon the upper face of the
inclined side bars 12, having bevelled inner faces, which clamp the sides of the
trough near its forward end. Thus the trough is wedged to place in the direction of
the rear, and to prevent a forward movement cleats 30 are secured to each side of the
trough adapted for contact with the rear side face of the cleats 28, as shown in
Figure 5. Thus while the trough may be lifted vertically upward and disengaged
from its support it is rendered incapable of moving laterally in the slightest degree.
Upon the working bed or floor of the trough a tapering roller 31 is held to roll
essentially from side to side, the periphery of which roller is preferably corrugated or
ribbed. This roller is detachably attached to a horizontal arm 32, pivoted at one end
to a cross-bar 33, located at the top and to the rear end of the framo a slight distance
from the rear cross-bar 11, as best shown in Figure 1, and the manner of connecting
the roller with the arm is as follows: At each end of the roller one end of a post 34
is pivoted, the upper ends of which posts are engaged by a clamp 35, each of which
clamps is swivelled upon the lower end of a rod 36, the upper ends of the rods being
threaded and made to pass upward through threaded apertures in the pivoted arm 32.

page_text: By reason of the inclination of the trough when in working position the rear rod is
longer than the forward one. The clamps are attached to the pivotal posts of the
rollers by means of pivotal pins or bolts, and the rods 36, when detached from the
roller, may be screwed upward out of the way, and to facilitate this movement a
ferrule or sleeve 37 is secured to each of the rods between their ends. The arm 32 is
guided in its lateral movement upon the frame by means of a block 38, having side
arms, which block is held to slide in recesses 39, formed in two spaced transverse
bars 40, secured to the upper side bars of the frame at or near their centre, as shown
in Figures 1 and 2. The upper end of the block is provided with a circular
projection which extends through and has movement in a longitudinal slot 41, formed
in the arm 32. Upon the upper extremities of the forward uprights of the frame the
ends of a yoke 42 are secured, and in the said yoke the forward ends of shafts 43
and 44 are journalled one at each side of the centre, as best shown in Figure 1.
These shafts are carried rearward in opposite directions, and are journalled at their
rear ends in suitable bearings 45, attached to the rear upper cross-bar of the frame, as
shown in Figure 3. These shafts have attached thereto, respectively, a pinion 46
and 47, the pinion upon the shaft 44 being located near the rear cross-bar 11, and the
pinion upon the shaft 43 near the parallel and adjacent cross-bar 33, upon which the
rear end of the arm 32 is pivoted. Upon the forward end of the shaft 43, within
the yoke 42, a crank-arm 48 is rigidly secured, the outer extremity of which crank-
arm is connected with the bracket 26 of the wing 23 of the trough by a
chain 49. A similar crank-arm 50 is secured to the forward end of the shaft 44,
which crank-arm at its outer end is attached by a chain 51 to the bracket of the
wing 24, as hest shown in Figure 2. The roller-carrying arm 32 is preferably
provided with a friction-roller 52, capable of contacting with the under side of the
forward member of the yoke 42.
The mechanism by which the shafts 43 and 44 and the roller-carrying arm 32 aro
manipulated consists of three gears of equal size, 53, 54, and 55, journailed between the
rear cross-bars 11 and 33 of the frame, which gears operate in connection with the
pinion 46 and 47. All the gears 53, 54, and 55 are placed in the same plane, and
the side gears are made to mesh with the centre gear. The side gear 53 is provided
upon the rear face with a toothed segment 56, the teeth of which segment are in
horizontal alignment with the teeth of the gear. The centre gear 51 is provided with
two toothed segments 57 and 58, one being located upon each side, the end of one
segment being essentially in alignment with the centre of the opposite segment and
the side gear 55 is provided with a toothed segment 59 upon its forward face, as
illustrated best in Figure 4.
The segments 56 and 57 are adapted to alternately mesh with the pinion 47, and
the segments 58 and 59 with the pinion 46, the object being to so rock the shafts 43
and 44 at stated intervals that their crank-arms 48 and 50 will be carried first to a
vertical position and then to their horizontal or normal position. The gear 55 is
secured upon a short longitudinal shaft 60, the inner end of which shaft extends
through the rear central guide-beam 40, and to the forward end of this shaft one
member of a crank-arm 61 is secured, the other member being journalled in the
opposed or forward guide-beam 40, as shown in Figure 1. This crank-arm 61 is
connected by a pitman 62 with the slide-block 38, connected with the arm 32. The
train of gearing is set in motion through the centre gear 51, and to that end the
spindle of the said gear is carried rearward through the cross-beam 11 of the frame,
and a crank-arni 63 is secured to the outer end of the spindle.
In operation as the crank-arm 63 is revolved the segment 56, meshing with the
pinion 47, elevates the wing 24 of the working-table of the trough, and the revolution
of the gear 55 causes the roller-carrying arm 32 to travel over the butter in the
direction of the opposite wing, and as the wing 24 is brought to the perpendicular
position illustrated in Figure 2, and slightly past the perpendicular, the butter upon
said wing is thrown upon the centre strip 22 of the working-table, to be pressed by
the roller upon its return. Immediately upon the release of the pinion 47 by the
segment 56 it is engaged by the segment 57 upon the central gear, which throws the

page_text: crank-arm 50 back to its normal position, enabling the wing 24 to drop to its normal
position upon the floor of the trough. At the same time the arm 32 is carried over
upon the centre strip 22 in the direction of the wing 24 just dropped, and the
segment 58, contacting with the pinion 46 elevates the wing 23, and as said wing is
brought to a position slightly beyond the perpendicular it deposits the butter just
rolle upon the central strip, and in the revolution of the gear 55 the segment 59
thereon contacts with the pinion 46 immediately after its release by the segment 58,
and the crank-arm 48 is restored to its normal or horizontal position to permit the
wing 23 to drop, and this movement is continued as long as desired, or until the
butter has been sufficiently worked.
It will be observed that the milk, water, or other liquid contained in the butter
will pass through the slots 21 in the partition 20 of the trough into the rear
chamber A.
The trough may be removed at any time by disconnecting the clamps 35 from the
posts pivoted to the roller 31 and screwing the rods 36 upward in the arm 32.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination with a trough having an auxiliary bottom or working-table
comprising a central fixed strip and wings hinged at each side of the same, of a
reciprocating arm, a roller carried by said arm adapted for contact with the working-
table, shafts capable of being alternately rocked, crank-arms secured to said shafts, and
a connection between the crank-arms and the wings of the working-table, substantially
as shown and described.
2. The combination, with a trough provided with an auxiliary bottom or working-
table consisting of a central rigid strip and wings hinged to each side of the said strip
