Improvements in the Construction of Milk-pails.
We, HENRICK KRISTIAN BORCHGREVINK, of Number 1021, Lake Avenue, and
JOHN FRANCIS JOHNSON, of Number 1025, Lake Avenue, both of the City of Racine,
in the County of Racine and State of Wisconsin, United States of America,
Manufacturers, 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:-
a
This invention has for its object the construction of a milk-pail designed to
receive the milk from the cow while the operation of milking is being performed,
while at the same time dirt, hair, and other refuse matter is kept out of the con-
tents of the pail, and the milk cooled and aerated, and to these ends, the said
invention consists, primarily, in providing the said milk-pail with a closed funnel-
shaped top, projecting downward into the pail, a screen in the bottom of said
pail-top, continuous closed band or collar rising from said pail-top,
and a removable sieve or screen suspended from said band or collar, with
the upper edge of the frame of said screen making a close fit with the top edge
of said band or collar; secondly, in the addition of a dirt-collecting cup pivotally
suspended from the closed top, just beneath the screen in the bottom of the latter,
so that said cup will always maintain a horizontal position; and finally in various
détails of construction and combination of parts, all as more fully explained here-
inafter, in connection with the accompanying drawings, and subsequently claimed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a partly sectional view of the upper part of one of the said improved
milk-pails."
Figure 2 is a plan view of the suspended dirt-collecting cup and milk-cooler
and aerator looking downward from the line 2-2 of Figure 1.
Figure 3 is a detail side elevation of said last named part, looking toward the
center from the line 3-3 of Figure 1.

Referring to the drawings, A represents the pail or receptacle for the milk,
which pail may be of sheet-metal, if preferred, with a rolled and strengthened
upper edge, a, as shown. B represents the top of the pail, comprising an annular
flange fitting just within the top of the pail, united, as by a bead c (which rests
on the top of the edge a) to an obliquely disposed upward and inward projecting
flat ring d, which in turn is united to a downward projecting obliquely disposed
flat ringe which inclines all around toward the center, in the shape of an inverted
truncated cone or funnel top, the central hole being fitted with a sieve or screen,
preferably a wire sieve f. We have shown these parts bc, d, e, as if they were all
pressed or stamped out of a single piece of sheet-metal, but if preferred they may
be made of separate pieces or strips soldered or seamed together. A vertical band
or collar
is soldered or otherwise secured to the described top, just about the
junction of the rings de, and preferably has an upper rolled, seamed or beaded
edge h, which may be stiffened with a wire as shown, if desired. C represents a

page_text: sieve or strainer, formed of an inclined annular strip of sheet-metal, with a wire-
screen bottom i, and having its upper edge preferably bent over outwardly as
shown at j, so as to fit over the rolled top h, of the collar g.
DD are ears, riveted or otherwise secured to the part of the top, for the recep
tion of the ends of the bail E. F F are hangers, preferably of wire, secured oppo-
site each other, as by solder, to the underside of the top B, and having preferably
open hooked lower ends, as best shown at k, Figure 3, for the reception of pintles
or trunnions m m, which have preferably downturned ends n n, and which project,
opposite to each other, from the edge of the annular oblique band o. This band
is in the shape of an inverted truncated cone or funnel-top, also, but its central
opening is united to a cup G, instead of to a screen section, and the upper annular
edge of the band o is preferably formed with a vertical edge p. H 1 are the ears
and bail on the pail A.
The operation of the device will be readily understood from the foregoing
description of its construction taken in connection with the accompanying draw-
ings. The pail is preferably held between the knees of the milker, in the usual
way, that is, tilted or inclined towards the animal, and the milk is directed within
the sieve C, striking and passing through the screen-bottom i, without spattering,
and falling within the conical part e of the top B and through the lower central
screen thereof, into the suspended flanged cup Go, and over the edge thereof
into a pail A. By reason of the described manner of suspending the said cup G 9,
the latter always remains in a horizontal position, irrespective of the angle to
which the pail has been tilted, and the milk, after passing through the two screens
named, escapes over the edge 7 of the cup in a clean pure condition, the small
heavier particles of dirt which have passed the screens dropping into the cup G
and the lighter of the said small particles being arrested by the described edge p
of the suspended device Go as the milk flows over, and gradually settling back
into the cup G, the said milk being further cooled and aerated in its described
passage. The amount of dirt, hair, and other refuse matter which is thus arrested
and kept out of the milk is astonishing and the milk does not require filtering
before use.
The several parts of the device may be very readily taken apart for cleansing
and the removal of the dirt and other refuse substance collected thereby. The
sieve or screen C can be quickly slipped from the top B, and the latter from the
pail A, and to remove the dirt-cup and aerator Go, it is only necessary to push
the latter upward to free it from the hooked ends of the hangers F F, to which
position it can be quickly restored, by a turn of the wrist, as the said hooked ends
of the hangers are preferably on opposite sides thereof.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is;
-
1. In a milk pail, the combination with a funnel-shaped top adapted to tightly
close said pail and projecting downward into the pail, of a screen in the bottom of
said pail-top, a continuous closed band or collar rising from said pail-top, and a
removable sieve or screen suspended from said band or collar, the upper edge of
the frame of said screen making a close fit with the top of said band or collar.
2. In a milk-pail, the combination with a closed funnel-shaped top, projecting
downward into the pail, and having a screen in its central bottom portion, of
hangers projecting downward from said top on each side of said central portion,
and a dirt-collecting cup, pivoted to said hangers and swinging free from contact
with the pail or top, so as to always maintain a horizontal position.
3. In a milk-pail, the combination with a closed top provided with a screen
in the bottom portion thereof, of a dirt-collecting cup pivotally suspended from
said top, so as to always maintain a horizontal position, and having an annular
inclined flange for cooling and acrating the milk as it flows over the edge thereof.
4. In a milk-pail, the combination with a closed funnel-shaped top, provided

page_text: with a screen in the bottom thereof, of a band or collar rising above said top, a
removable sieve or screen supported by said band or collar, and a flanged dirt-
collecting and milk-cooling cup pivotally suspended from the under side of said
top.
