Application filed .TulylO,

' This, invention relates to strainer and cover constructions for receptacles. Although the invention is capable of use in connection with various types of containers, it is particularly adapted for use in connection with milk pails, during the milking operation and during the process of treating the milk after the same has been taken from the cows.

It is anobject of this invention, therefore, to provide an improved strainer and cover for receptacles. 7

It is more specifically an object of this invention to provide such a strainer and cover which may be adjustable to fit receptacles of different sizes.

Still another object of the invention is to provide a strainer and a cover adapted to lit the tops of varioussized pails having upwardly flaring surfaces.

These and other objects of the invention will more fully appear from the following description made in connection with the "accompanying drawings, wherein like characters refer to the same or similar parts throughout the several views, and in which .-Fig. 1 is I applied to a pail, a portion of the pail being broken away;

In the drawings, an upwardly flaring pail 6 of standard construction is illustrated i having an outwardly extending roll 7 formed at itsupper end, a bales and ears 9 t0 Which the baleis se'curedf An arcuately shaped. strip 1O composed of flat resilient sheet material is provided having a plurality of spaced apertures l0 'shown as substantially horizontally extending slots formed adjacent one end thereof and a tongue 1O at its other end formed as shown cutting a slot partially across the strip adjacent the end 10". Theupper edge of strip 10 has a roll 1O formed thereon extending from one end of the strip to within ashort distance from the other end thereof.

a perspective view of the device 1926. Serial No. 121,640. I

A stiffening rod 10 is secured in theroll 10 and projects outwardly therefrom at one end and terminates short of the other end of the roll. An arcuate strip 11-, also composed from flat resilient sheet material, is provlded, having spaced apertures 11 adjacent one end, shown as being substantially trans-- yerse slots, and a projecting tongue 11 at 1ts other end, the tongue 11 being shown as pro ecting longitudinally from the end of the strip 11. V

Strip l0 being of resilient material may be circularly bent as shown in Fig. 1; the tongue 10 may be upwardly bent to the dotted position shown in Fig. 5, and the tongue engaged with any one of theapertures 10 the projecting end of the stiffening rod 10 fitting within the opposite end of the roll 10 as the two ends of the strips are olned. It can be seenthat by placing the tongue 10 in the different apertures 10 the diameter of the band or ring formed by the strip 10 when the ends are joined may be considerably varied. The two ends of the strip may be rigidly secured together by bending the tongue 1 0 downwardly from the dotted position, as shown'in Fig. .5, to the position of the tongueshown, in full lines in Fig. 5. The ends of strip 10 having been oined to form a band of suitable. diameter, the same may be'placed with its outer surface against the inner surface of a container or pailsuch as'the pail 6, the roll 10 of the band abutting the roll 7 of the pail, or if no roll or bead is provided on the pail, the roll l0 abutting the top edge of the pail. Due to the, arcuate formation of the strip 10, as the ends of the same are joined to form a band, the band will be given an upwardly flaring shape so that the whole outer surface of the band will contact the inner surface of the pail adjacent the top thereof. The strip 10 will form the outer band of the strainer and cover. i

The ends of the strip 11 may now be joined bycurving" the strip to form a rough circle and inserting the tongue 11 in one of the apertures 11 the outer diameter of the inner band so formed being made by proper adjustment of the tongue 11 in the aper-, tures 11 to approximately equal the inner diameter of the outer band 10.- The ends of the stripll Inlay be secured by bending the tongue 1 1 touthe dotted position shown in Fig. 4e, inserting the tongue in one of the apertures 11 and reversely bending the material is placed to extend somewhat below the outer band 10 with portions thereof contacting the sides of the band at all pointson its lower inner circumference The inner band 11 may now be inserted within the.

outline of the outer band 10 on top of the portions of the flexible sheet member 12 which cont-act'the inner surfaces of the outer band, and the co operating inner surface of the outer band and theouter surface of the inner band will securely clamp the straining member 12 in operative position.'

The band 11 being formed from an arcuate strip will have upwardly flaring surfaces so that the outer sides of the band will closely conform to the inner surface ofthejouter band. The strainer and cover may be assembled before or after the outer band is positioned one receptacle or pail, but is preferably assembled before the outer band is seated on the receptacle.

If desired, either or both of the tongues 10' and 11 instead of being first outwardly bent from the main body portions of the bands as the ends of the two bands are joined, may be inwardly bent. The, ends of the bands will then be joined at opposite sides thereof from the joined sides shown in the drawings. The position of tongue 10 adjacent the end of the band 10 may be varied if desired. Various types of apertures andjton ues may be formed on the strips 10 and 11 fi when the ends of the strips may be secured together. 7 i 3 Thefdevice when applied to a pail will provide a strainer which can be used at the time a cow is milked to strain the milk and keep all sediment falling from the cows andotherwisev blowing about from falling into the milk. If the milk from the cow is bloody or gargety, this will be indicated on the strainer member. The quality of'the milk will accordingly be increased by use of thepresent invention. as sediment that would otherwise fall into the pail wouldd1ssolt e to a. certain extent in the milk and the value of the milk would accordingly be decreased. There will be no opportunity for the milker' to get his hands into the pail while the cows are being milked, and accordingly drier and cleanli'er milking will be accomplished. The

strainer and. coverwill notget in the way ofthe milking operation.

Preferably cheesecloth is used for the straining member 1 2 and this cloth can be readily removed for cleaning b simply dissemblingt-he two bands 10 an 11 an 7 ing the straining member 12 from theouter band whereupon the same may be readily washed. If wire mesh is used for the strainthevsame has been run through a separator.

This cooling process is usually accomplished by allowing the pails of milk to stand in .cold water for some length of time and allowing milk to be exposed to the airto take out all the animal heat frorn the milk. With the present device the pails 'may be 0on veniently placed in water andthe device will provide a cover over the pails which will prevent the milk from becoming fouled and yet will permit the access of air to the milk.

The device will alsohavehigh utility for use in other connectionsthanin milking or in treating milk. l

It will, ofcours'e, be. understood that various changes may be made in the form, details, arrangements and proportions of the various parts without departing from'the scope of the present invention which, gen erally stated, consists in the matter shown and described and set forth in the following claims.
