I, GUY SAMUEL FRAZEY, of Jersey City, in the State of New Jersey, United
States of America, Gentleman, do hereby declare the nature of my said inven-
tion for "IMPROVEMENTS IN DEVICES FOR MILKING COWS AND STRAINING
AND COOLING MILK, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention consists in certain devices to be used in milking cows, in a strainer
and receiver connected therewith; in a pail adapted to receive said straining and
milking devices; to secure the ventilation of the contents of said pail, all in con-
nection with a pan to secure either deep or shallow setting, and in a case or box
adapted to receive said pails for the purpose of cooling the milk therein and
raising the cream.

A represents my improved pail or can. The strainer B is shown as of funnel
shape but it may be of any other desired or convenient contour. This vessel B, is
provided in its upper portion with a strainer or sieve C, of gauze or other suitable
material through which the milk first passes, and in its bottom with another
strainer a, which may if desired be of finer mesh than the other strainer C, in
order to secure a more perfect straining of the milk. Below this lower strainer a,
is situated a cup shaped valve b, which is eccentrically pivoted within the neck of
the strainer B, upon suitable journals; said valve while the strainer and can remain
Price d I

page_text: in upright position tilts downward at an angle from the horizontal as shown in
figure 1, and thus permits of milk flowing therein to overflow down into the can,
but should the can at any time be tipped or upset the milk therein in its endeavour
to escape from the can will press against the depending portion of said valve and
force it to a horizontal position and thus close the exit, thereby preventing the
escape of the milk from the can. f, represents an eye to which the lower end of a
rod is attached. This rod extends outward and upward as shown to permit of the
valve b, being readily turned thereby in either direction as desired. This rod how-
ever may be dispensed with if desired as it is not essential to the working of the
cup valve which is automatic in its action. The valve b, is provided with a cup rim
in order that any dirt accidently passing through the strainers may settle therein.
The strainers and other parts of this device are all readily removable in order that
they may be easily cleaned or repaired. d, represents a ventilating tube attached
to the outside of the strainer or receiver as shown, whose lower end connects with
an opening in the side walls of said receiver and strainer. The object of this tube d,
is to allow of the animal heat having free vent to and from the lower end of the
receiver and from the can during the process of milking. The tube extends upward
a sufficient distance to prevent the milk on its passage downward rising above and
flowing out of the top thereof. To the upper end of a tube e, in the top of the
vessel B, is attached the lower end or neck of a bulb shaped teat receiver D, of
rubber, leather, or other suitable elastic material; there may be either one or more
of these tubes e, and teat receivers attached to the straining vessel B, as desired;
I do not limit myself to the employment of any specific number of either. This
teat receiver D, has at its top a circular orifice g, within which the teat of the cow
is inserted; in one side of the valve is circular or other shaped opening h, through
which when the teat of the cow is inserted the hand of the milker is passed for the
purpose of grasping the teat and drawing the milk. The orifice h, has a flap
extending therearound and the opening h, is made so small that on the insertion
therethrough of the milker's hand said flap will tightly embrace the milker's wrist
however small it may be, thereby entirely excluding communication through said
opening h, with the outer atmosphere while said bulbs are in use.
By the use of these bulb shaped teat receivers the milk in its passage from the
cow to the can A, is not subjected to any poisonous or deleterious odors that may
be adjacent. Thus the milk is not liable to become contaminated in its passage
from the cow to the pail or can as would be the case were it allowed to pass
through the surrounding atmosphere. Moreover any dust or dirt flying around
cannot by any possibility reach the milk as it is by this apparatus entirely isolated
from contact therewith. These bulbs furnish, moreover, a protecting covering to
the hands of the milker which is very advantageous in cold weather and as the
material of which these teat receiving bulbs are constructed is soft and pliant the
edges of the orifices g, will close against the teats in a similar manner to that in
which the mouth of a calf would and as the milker's hand will be warm and the
warmth therefrom be confined within the bulbs the compression around and warmth
imparted to the teat while milking with this device will conform very nearly to the
impression produced thereon by a calf when sucking; therefore the cow will be
induced to give milk more freely by the use of this device than would be the case
were these characteristics absent.
The strainer a, is as shown in figure 2, of the drawing held in place by two
wedge shaped tubes; the straining material being first placed over the top of the
inner tube and the outer tube then slidden telescopically over the inner one thereby
securely holding the strainer in position and stretching it tightly.
The pail cover has an upwardly extending tube j, which the neck of the straining
vessel B, fits. In the side of the pail is a window of glass or other transparent
material, through which the height of the milk can be ascertained. E represents
the cover of the pail or receiver which has upwardly and downwardly depending
flanges 1, 2, as shown having notches around the top flange allowing water to be
distributed over the submerged part of the cover.

page_text: The upwardly extending tube has a cap 1, having ventilating openings in the top
to which is pivoted a perforated rotating disc m, in order that communication
between the interior of the can and the outer air may be unimpeded or entirely
prevented as desired. n, represents a strip of stout material preferably wood placed
across the top of the pail cover and resting upon the rim 1, thereof and forming a
seat upon which when milking the person may sit without bending the cover, the
weight of such person being thus evenly distributed around the edges of the cover
and the sagging down thereof and of the pail prevented; the rim 1, holds about
one-half to one-inch of cool water while the cream is being raised.
ọ, represents an inner circumferential rim or flange in the pail A, supporting a
pan F, which may be of any desired depth, about one-half of the depth of the pail A,
being the most desirable; if desired two or more of such pans may be employed
each of less depth than F, said pans in such case being placed the lower one upon
the rim or flange o and those above resting upon those beneath. Such duplication
of the pan F, is advantageous as thereby the volume of milk can be divided so as
to increase the surface to which the cream can rise and the distance to which it
must rise is less than when only one pan is used. When it is desired to use two or
more pans the flange o, would be placed at or near the bottom of the can. The
pan F, has on one side a straight portion p, having a hole or opening q, through
which the excess of milk flowing into said pan will flow to the enclosing pail. By
forming one portion of the pan with a flat surface the flow of the milk through the
hole q, to the pail A, will be free and unimpeded; this hole will be closed by a
slide valve to prevent cream or milk from pouring through when being skimmed or
being removed. A loop or handle is provided on the inner face of the pan F, by
means of which said pan can be raised and lowered. 8, represents a window in the
side of the pan, the pan is placed within the pail with said window opposite the
window k, by looking through said windows the height of the cream can be readily
ascertained. It is well known that the caseine and other qualities contained in
milk that it is desired to extract therefrom for use in butter and cheese making are
obtainable more readily and in larger quantities by means of the shallow setting
method than by the deep setting, and that butter and cheese manufactured from
milk subjected to shallow setting is superior to and brings a higher price in market
than do similar articles produced from milk subjected to deep setting owing to the
added richness of the product of the shallow setting method. By my improvements
I am enabled at will to readily employ either of these methods by a very simple
and efficient arrangement and at a cost not exceeding that at which deep setting
alone is ordinarily accomplished.
When shallow setting is desired the pan F, is placed within the pail A, with its
bottom resting upon the flange d, the cover E is then applied and the strainer B,
placed upon the tube j. The milk is then passed through said strainer either as it
is drawn from the cow or by pouring it therein down through said tube j, into the
pan F, the excess beyond its capacity flowing through the orifice therein to the
enclosing pail. When deep setting is desired the pan F is dispensed with and
the milk allowed to flow directly into the pail through the strainer and tube.
While this pail and pan can be readily used either with or without a suitable
straining device still it is my intention to use the same in conjunction therewith,.
and also in conjunction with the arrangement for cooling the milk and raising the
cream therein here-after described.
G, represents a box or case of any suitable shape to adapt the same to receive
one or more of my milk cans. In the form shown in the drawings the box is
adapted to receive three of such cans, the box being divided into the requisite
number of compartments by transverse strips t, and the lid or cover H, is shown as
formed in three independent hinged sections each having on its top a box I within
which is placed ice; the number of these boxes may be increased or diminished and
the lid may be formed of more or less sections. Each box I, has a cap or cover J,
which may either be hinged thereto and secured by any suitable retaining device
or it may consist of a cap adapted to slide across upon said boxes as desired.
"

page_text: ..
Perforations u, are formed in the bottoms of the boxes I, through which the water
from the melting ice drops upon the cans beneath; by increasing the area of these
perforations u, the water will not only drop upon the tops of the cans but alsó
within the box surrounding the cans.
At the inner ends of the box G, are transverse ledges or gutters v, which are
recessed at their top inner edges as shown at w, to receive and support the
perforated tubes x, on the bottom of the ice boxes. When the sectional cover H,
is closed the end tube sections x, will rest within such recesses w, and also within
the recessed or depressed portions y, in the strips t, and connect together_thus
forming continuous tubes through which the water can flow from the pipe K, at
one end of the box to the other end thereof.
K represents a pipe or tube through which water from any convenient source is
supplied to the tubes x. The water entering such tube is cooled in its passage
under the ice boxes, a small portion of this water and that resulting from the
melting of the ice trickles down through the perforations in said tubes, but the
main portion of the water passes along said tubes to the gutter at the opposite end
of the box G, from whence it flows through the pipe L, to or near the bottom of
the box. An overflow opening z, is formed in or near the end of the box A, at
which the water enters, through which the surplus is discharged thereby ensuring
a constant circulation of water within said box and the rapid cooling of the milk
and raising of the cream in the cans placed therein.
•
The cans are placed within the box with the ventilator tube d, to one side of the
perforation in the ice boxes in order that the perforated disk m, may remain open
to allow of the escape of the animal heat from the milk. To remove the can from
the box G, the cover H, is turned back the perforated disk closed and the can tilted
slightly to allow the water that has collected within the rim to flow off through
the notches therein; the can can then be removed without disturbing the others
or changing the temperature in any perceptible degree or exposing the surface of
the milk not ready to be removed or skimmed. If desired a slit may be formed in
said rim near the bottom or from the top to bottom thereof guarded by a sliding
shutter or valve by sliding which upward the water within the rim can readily
flow off.
