Patented May 5, 1925.
rnmw OSCAR- EL ER, or rRorHE'rs'rowN; ILLINOIS.
Application flied Fehrnary 23; 1923. Serial at; 621,827.
To" all wfto m' it may concern 4 Be it knownthat 1 FERRY 01 Hunter, a citizen of the Uni-ted- States, residing at Prophetstown, in the county of VVliitesidc and State of Illinois, have invented new and? useful 1 nprovements" inf Strai1'rers,.of which the following is; a specificat on.
This invention relates to ,stra1ners for removing impurities and foreignmatter from milk orot-her liquids:
The object is to provide straining means for this purpose which may be applied 0 bottles; cans of other receptacles-having their, necksprovided with the necessary" threads and of the proper diameter, all of the parts of the strainer being separably" held to the mouth of the reoeptaclein such manner as to prevent accidental displacement and to fibrous material used in the device, when the same has become saturated or clogged with accumulations, and to" cleanseall the parts of the strainer in order to maintain the same in a sanitary condition.
A full and complete understanding of the invention may be obtained from a consideration of the following'detailed description, taken in connection with the accompanying drawing forming a part of this specification; it being understood that while the drawing shows a practical form of the invention, the latter is not confined to strict conformity with the showing thereof, but may be changed or modified, so long as such changes or modifications mark nomaterial departure from the salient features of the invention, as specifically pointed out in the appended claims.
Referring to the drawings, in which similar'reference characters designate cor responding parts throughout the severalfig- Fig. 1 is an inverted, longitudinal section through the mouth of a receptacle having the improved strainer applied thereto.
Fig. 2 isa horizontal sectional view, taken on the line 22 of Fig.- 1, and looking in the direction indicated by the arrows.
Fig. 3 is a top plan view of the perforated ca i Vhile the improved strainer has been shown in the drawing,v
mouth of a glass or porcelain reeeptacl'ein the form of a bottle or jar, it is'to be understood that the same may be used in connection" with an ordinary metalmilk can, or
as applied to the any other similar receptacle, where it is de-,
sired to strain or filter liquid of any lrind' capable, of being accumulations in this manner.
freedof foreign matter or' In the drawing, there is illustrated a portion' of a jar or bottle 1', which may be formed of any suitable material and having its open end cut off square, as at 2, to providea mouth, and also to act as a bearing surface for the reception of the straining elements. This flat surface" 2 in the event the device is used on a metal can, may be formed by an inturiied flange, as will be easily understood v r The outer surface of the reduced ne'ck'por tion 3' of the receptacle, is provided with threads 4, formed in an appropriatemanner depending on the ina'terialconiprising' the receptacle, said threads extending substan tially one-half the" length of the neck.
Adapted to he threaded one are neck of tlie receptacle, is a li'n'etalliccap 5 formed of some noncorrosive metal, and comprising a fiat cover plate 6 having its peripheral margin formed into an integral, threadedflange 7 of substantially equal height with the height of the threads on the neck of the bottle, the marginal edge of the flange being rolled into a strengthening bead 8 to pre vent distortion of the same.
The flat cover 6 is provided throughout its area with a plurality of perforations 9, with the exception of a continuous imperforate margin 10 located adjacent to the flange as at 11, between the base of the flange and the beginning of the threads thereon, for facilitating the turning on or off of the cap in the usual manner.
A wire gauze strainer 12 formed of suitable non-corrosive material, and made circular to correspond in diameter, with the outer edge of the flat surface 2 at the mouth of the bottle, is adapted to rest on said flat 7, which has its outer face fluted,
surface, and has its outer end embedded in a lead or solder ring 13 to prevent unraveland undue dlStO1t-1011 rial, capable of arresting and holding the smaller particles or impurities. The cap 5 is then applied to the mouth of the receptacle and screwed tightly thereon, when the imperforate margin clamps and compresses the absorbent material between the same and the flat end of the neck of the receptacle, the gauze being interposed therebetween. By this arrangement, the outer edges of the gauze and cotton provide a gasket between the outer edge of the neck and the top or cover.
li ith this arrangement, it will be seen that it is impossible for any of the contents of the receptacle to pass around the marginal edge of the absorbent material, but is forced to pass straight through the same, the wire gauze arresting the larger particles and sustaining the absorbent material from the inside, while the cover plate 6 of the cap supports the said material on the outside and allows the flow of'the liquid contents from the container without interference.
The fiber of the cotton or other material is thus held in position for the perforated portion of the cap on one side and the screen on the other, thus avoiding the formation of channels or gulleys through the cotton by the flow of the liquid, as the said fibers can not move nor beforced apart to form such openings.
From the foregoing it will be seen that a simple, cheaply manufactured, sanitary filter or strainer has been provided for straining milk or other liquids and Which may be readily applied in position on the mouth of a bottle, jar, can or other receptacle, and that the same may be readily removed therefrom for the purpose of cleansing the same or for replacing the absorbent material, every part of the strainer being capable of thorough cleansing.
What is claimed is In combination with a receptacle having an exteriorly threaded neck, with the open end of the neck fiat, a circular gauze disc bearing against the flat end of the neck and extending to the outer edge thereof, a circular layer of absorbent material placed over the gauze disc and extending to the outer edge thereof, and a detachable cap having a peripheral threaded inturned flange for engagement with the neck of the receptacle to clamp the outer edges of both the gauze disc and absorbent material to the flat open end of the neck, said cap having its cover plate perforated except around the margin where it is opposed to the fiat end of said neck, whereby the imperforate portion of the cover plate engages and holds the outer edges of the gauze disc and the cotton against the end of the neck, said disk and absorbent material forming a gasket between the neck and the imperforate portion of the cap so as to prevent the liquid contents from passing around the marginal edges of said disk and absorbent material.
In testimony, that I claim the foregoing as my own, I have hereto ailixed my signature.
PERRY OSCAR HELLER.
