' MILK-STRAINEB ATTACHMENT. 1 I i if Application filed July 21,

To all whom itma i concern: 1 Be it'known that I, Gus'rav P. LAGEMANN, a citizenofthe United States, residing at Luverne, in the county of Rock and-State of Minnesota, have invented certain new and useful Improvements in Milk-Strainer Attachmeiits, of which. the following is a specificat-ion. I f This invention relates to strainers and supportingnieans therefor, and has for its primary object the provision, in a manner as hereinafter set forth, of 'a strainer which may be suspended entirely within illiGdilOUtl]. of a receiving vessel. I

' Another object is the provision, in a manner as hereina'ft'er set forth, of a strainer so constructed as to obviate the liability of an overflow-through deposits of sediment upon the'soreen in the bottom thereof.

Another object of this invention is to pro vide a device ofthis character including a tubular body converging toward the foraminous discharge end and with means for suspending the body within va receptacle and maintainingthe same in vertical position therein. Still another object is the provision of'a strainer and supporting means therefor, which will be strong, durable and inexpensive to manufacture.

The invention will be best understood: from a consideration of the following; detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding that the invention isnot confined to any strictconformity with the showing of the drawings, but may be changed and modified, so long as such changes and modifications mark no material departure from the salient features ofthe invention as expressed in the appended claims.

In the drawings: Figure 1 is a side elevation ofa portion of a milk can, partly in section, and showing the device embodying this inventionapplied thereto. I j

Figure 2 is a top plan View of the invention.' m

Fig. 3 is a vertical transverse section of the same taken on the line 33 of. Fig. '2, and p I I p Fig. i is a view showing a modification of the attaching means. I

Referring now tothe drawings in detail, wherein like numerals of reference indicate 1923. Serial- No. 653,049.

corresponding parts throughout the several nular upper, portion 2, a conoidal shapedintermediate portion 3 and a dependinganiiular lowerportioni, of less diameter than the upper portion, preferably formed in one piece, although it is'obvious that three seciinished article.

A portion of the intermediate portion, extending from the lower edge of the upper tionsinav be fitted together vto form the portion to the upper edge of the lower p'or-I tion, is removed and across the opening thus formed is secured a section of copper gauze screen 5, of the type commonly used in milk strainers. The lower edge of this screen contacts with the usual straining screen 6,

stretched across the lower part of the porti on 3, at is iunctui'e with the lower annular portion.

Provision, is made for suspending the strainer in a can, by attaching to the upper portion '2, of the strainer, a plate member 7 of less width than length, and slightly curved transversely to. conform to the curve of the strainer, which plate is of sufficient length to contact with a goodly portion of the innersurface of the can neck. as shown in Fig. 1, and has its upper edge curved over to form a hook 8, which is positioned over the edge ofthe neck of the can, as shown. Connection may be made between the support and strainer by rivets 9, or other suitable means.

In Fig. 4c, is shown modification of the supportingmeans for the'strainer. Here a support is provided for the strainer which may be easily removed, should itbe desirable to do so, and it comprises a frame preferably of wire, having two spaced leg meme bers 1010 which may be bent in appropriate places at 11 and 12, to conform to the shape of -the funnel which they are to support. Each of the legs, at one end, is

bent to provide hooks 13, which engage the :;lower edge of the funnel, and at a distance upward equal to the height of the funnel each leg is bent inward as at 14, downward and back upon itself as at 15, to form, a.

hook, the back bent portion passing up and back over the portion 14, and extended 0utward forming thel orizontal portion 16,

where a down bend is made as at 17, to form a second hook 18, opposite the first. This second hook, like the first, is formed by bending the material back upon itself and as shown it passes up and along the under surface of 16, until it abuts 10, where it extends straight down, leaving 10 at 11, but

continues down about half the length of the leg" 10, when it is bent laterally to form the curved brace 19, which separates the two leg members and the two sets of hooks.

It will be seen from the above paragraph that a support may be had for any size strainer, which will be easily applied, and easily made to conform to the shape of the strainer body, by simply bending the legs 10, at the proper points, to fit the curves in the strainer. The portion 19, serves as a brace and support, as does 7, in the other form, the body of the strainer in both in stances being held free from one side of the can neck and independent of the size of the neck.

Having thus described the invention, what is claimed as new is 1. A device of the class described, co1nprisinga tubular body converging toward the discharge end and with a foraminous closure at said discharge end, a supporting member attached to said body at its larger end and extended upwardly into a hook adapted to engage over the rim ot a receptacle and extended downwardly and adapted to bear against the inner face of the adjacent wall of the receptacle, and thereby support the body in vertical. position.

2. A device of the class described, comprising a tubular body converging toward the discharge end and with a foraminous closure at said discharge end and with a portion of one side of foraniinous material merging into tae toraininous closure, a sup-- porting member attached to said body at its larger end and at the side opposite to the foraminous side portion, and extended upwardly into a hook adapted to engage over the rim of a receptacle and extended clownwardly and adapted to bear against the inner face of the adjacent wall of the receptacle, and thereby support the body in vertical position and spaced from one wall of the receptacle.
