IMPROVEMENTS IN STRAINERS FOR MILK AND OTHER LIQUIDS
Year: 1885

page_text: COMPLETE SPECIFICATION:
I JOSHUA L. ABELL, of 128 State Street Chicago, in the county of Cook and.
state of Illinois in the United States of America, Manufacturer, do hereby declare
the nature of this invention for "IMPROVEMENTS IN STRAINERS FOR MILK AND
OTHER LIQUIDS" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The object of my invention is to construct a strainer for milk and other liquids
that will not clog, but, will deposit the silt in a receptacle away from the screen
thus making it self-cleaning.
In the drawing, a is the body of the strainer into which is passed a cylinder b,
so as to project a short distance into it so as to form an offset or shoulder at i,
within the bowl a. Upon said cylinder is attached a strainer d, either conical as
shown at e or convex as indicated by the broken line d. Said strainer may also
be made flat, or even concave, and still answer the purpose though not so well.
As shown in the drawing it is an upward pointing cone composed of a screen, or
screens, c, surmounted by a solid apex e. The entire drawing being a central
vertical section of the strainer also shows the lower part of the screen in the form
of a parabola, but said base of the screen may also be made flat or inclined like
the sides of a flat cone.
Upon the bowl, or body a, is placed a funnel f, having a discharge pipe g, either
as a short pipe which, preferably, is made tapering towards its discharging end, or,
as a simple opening. Said discharge pipe: terminates near the base of the apex e,
of the cone.
When liquids are poured into the funnel e, the pipe 9, concentrates the
disebarging fluid against the sides of the screen of the cone c so as to pass the
liquid through it while the solid matter will glance off and fall down on the base
or depression h, of the strainer from which it will be washed off over the sides of
the cylinder b, and fall into the recess or pool i; there; by a well known law of
hydraulics; where the fluid is quiet, and therefore most favorable for the deposit
of suspended solids, it will deposit its solid matter.
The main current of all the liquid that fails to pass through the screen passes
outward in the direction indicated by the arrow, from this the deposit of the solid
matter is formed as it rises upward and flows back towards the screen; most of the
liquid passing laterally through the upper part of the screen when the body a, is_
filled to near the base of the cone d.

page_text: The motion of the fluid down the conical screen c, is more favorable to cause the
revolving motion of the fluid as indicated by the arrow.
The apex e of the cone is made solid for convenience in construction. It may be
a continuous screen if preferred.
The cone or screen is also made so as to be removable from the cylinder in the
same manner as a slip-cover, and under said screen, and so as to be held between
the contact surfaces of the cylinder and cone may be placed a cloth for the still
more complete straining of liquids.
The essential features of my invention are the bowl a and cylinder 6 projecting
for a short distance into the bowl a, so as to form a pool or recess i, on the outside
of the cylinder, and a screen covering the end of the cylinder either in the form of
a cone as shown, or a convex surface as shown by the broken line d, or in any of
the other forms, as already mentioned.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st A device for straining milk and other liquids, consisting of the bowl a,
cylinder b, and strainer c. Said cylinder covered by the strainer c projecting into
the bowl a, to form the shoulder or pool i upon the outside of said cylinder,
substantially as specified.
2nd The bowl a, cylinder b, projecting into said bowl so as to form a pool i
around the outside of said cylinder. Said cylinder being covered by a strainer, in
combination with the funnel f, substantially as specified.
3rd The bowl a, cylinder b, projecting into said bowl so as to form a pool i
around the outside of said cylinder, said cylinder being covered by a strainer in
combination with the funnel f, provided with a pipe 9 substantially as specified.
4th The bowl a cylinder b, projecting into said bowl so as to form a pool i,
around the outside of said cylinder, said cylinder being covered by a conical and
upward pointing strainer c, having depressions h, at its base, in combination with
a funnel f, having a discharge pipe g, substantially as specified.
5th A device for straining milk, and other liquids, consisting of the bowl a,
cylinder b, and removable strainer c, covering the end of the cylinder b. The
cylinder and bowl being united so as to form the pool i; substantially as specified.
