Patented Apr. 22, 1941 1 Claim.

This invention relates to miik strainers, and

aims to provide an improvement whereby the operation of straining milk to free it of sediment and solid impurities is made more efficient, economical, and sanitary. Time also is saved by the utilization of this improvement, by permitting the milk to pass through more rapidly without having to jar the strainer, which might break the cotton filter and let sediment through, thus resulting in rejected milk.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-numbered parts in the accompanying drawing.

Referring briefly to the drawing, Figure 1 is a front elevational view, partly in section and with parts broken away, of a strainer mounted on a standard funnel and provided with this improvement.

Figure 2 is a plan view of the same.

Figure 3 is a perspective view of the strainer with the improvement or attachment secured thereon.

Referring in detail to the drawing, the numeral It] indicates a standard funnel having the The strainer l2 comprises a cylindrical wall Hi from which a frusto-conical neck I 4 depends, the latter having an opening !5 at its bottom. A reduced cylindrical wall I6 depends from the bottom of the neck [4 around the opening I5. A disc H, of small mesh perforated metal, covers the opening l5 and serves to catch coarser sediment in the milk poured into the strainer from the top.

The bottom opening 18 of the wall It is adapted to be covered by a cloth disc l9, this cloth being an extra fine weave cheesecloth, a fine weave nainsook, or a proper weave muslin. A ring 20 having an up-turned flange 2|, is adapted to clamp the cloth disc l9 against; the

bottom peripheral edge of the wall Iii. Thus it is impossible for any milk to pass around the A diametrical cross rib 22 is integral with the ring 20 and therefrom, at right angles thereto, a semi-disc-like fin 23 projects downwardly.

The wall Hi of the strainer 12 is provided with a pivoted handle 24 for carrying the same in inverted position. When the ring 20 has been secured in place, the handle 26 is swung into the position shown in Figure 1, and serves as a look, by its contact, at two diametrically opposed points, as shown, to prevent loosening of the ring or the cloth disc H3. The latter may be removed and replaced with a new disc of cloth as often as desired. The spaced and notched wings 25 serve to support the strainer l2 firmly above the funnel I0 and at the same time permit the exit of air therebetween.

Obviously, modifications in form and structure may be made without departing from the spirit and scope of the invention.

I claim:

In a device of the class described having a depending cylindrical wall, an arched handle having its ends pivotally secured at diametrically opposite points to the outer side of said wall, a horizontal ring adapted to be secured against the lower periphery of said wall, said ring having a peripheral flange'extending upwardly at right angles t'o-said'ring and adapted to engage the outside of said wall,'a strainer cloth or the like serving to lock said ring against said lower pe ripheral wall.

CONRAD WARE.
