DEVICE FOR STRAINING LIQUIDS.
SPECIFICATION forming part of Letters Patent No. 752,019, dated February 16, 1904. Application filed May 13, 1903. Serial No. 156,995. (F0 model.)
To all whom, it may concern:
Be it known that I, J osnrn H. ADWEN, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Devices for Straining Liquids, which improvement is fully set forth in the following specification and shown in the accompanying drawings.
My invention relates to strainers generally, but more particularly to a class of cheaplyconstructed and inexpensive straining devices to be once used and thrown away. These cheap strainers are designed, among other things, to be used for straining remnants of fluids of any kind, including oily or viscid fluids, such as varnishes, paints, oils, andthe like used in painting, liquids and fluids common to the drug trade, &c. These strainers each comprise two sections or plies of thin material in the form of sheets, preferably of some fibrous substance, as paper, the sections being made either single or two joined at their edges in a pair, as may be found convenient. The sections are all alike as to their outer forms or perimeters and each having a series of corresponding openings formed through it. In constructing these strainers the meeting faces of two of the sections are first sized with an adhesive substance, and a thin sheet of porous or finely-perforated straining material, as cotton-cloth or its equivalent, through the meshes of which the liquid may pass, is then placed upon one section to cover the openings therein. The two sections are placed evenly together and so as to coincide with the sheet of straining material between them and in contact with their sized surfaces, the whole being pressed and dried, and when ready the body is given a conical form and used commonly with a cup having a perforated bottom.
The inventionis hereinafter more fully described, and particularly pointed out in the claims, reference being had in this specification to the accompanying drawings, forming a part thereof.
Figure 1 is a plan of a double sheet or section going to form the body of the strainer, with the sheet of straining material placed thereon. Fig. 2 shows the device after the two sections of the body are folded to inclose the sheet of straining material. Fig. 3 is aplan of the completed strainer placed in the hold- 'ing-cup ready for use. Fig. 4|: is a vertical axial section of the holding-cup, showing the conical strainer in side elevation. Fig. 5, drawn to an enlarged scale, is an axial section at one side of the strainer drawn to show more clearly the relative positions of the associated parts. Fig. 6 is a plan of a section made single. Fig. '7 is an axial section of a part of the holding-cup and associated part of the strainer, showing one of the catches for holding the strainer.
A B in the drawings are two corresponding end sections or parts of a single piece or sheet of suitable material, as paper, celluloid, or the like, these sections being alike and adapted to fold one upon the other along the dotted line a to form the body of the strainer. Each part A B is formed with a central circular opening I) and four, more or less, sectoral openings 0, concentric with the central opening 2'), there being a narrow ring it between each series of sect-oral openings and the central openings and a broad ring or band 2 outside of each series of sectoral openings, as shown in Fig. 1. The peripheries of the bodysections A B are preferably made polygonal in form, as shown in Figs. 1 and 2, the middle dotted line a constituting a side common to both figures.
C is a sheet of straining material, it being usually cheese-cloth, filtering-paper, or similar substance adapted to have the liquids pass through it. The two meeting faces of the sections A B are covered with .glue or other adhesive liquid and folded one upon the other, the straining-sheet C being between them, all being pressed into one solid body, as shown in Fig. 2. In thus forming this flat body the straining-sheet is placed in a manner to cover all the openings 7) and c 0 c 0 through the sections A B, the sections being accurately in position one upon the other, so the openings therein shall register one with the other, as
shown.
For the purpose of giving the strainer a conical form, as shown in Fig. a, a side of each section A Bis primarily correspondingly 1 0 cut away at cl 0, the radial bars f f and g g being brought to overlap, as shown in Figs. 3
and 4:, in completing the strainer, said bars being secured together by some suitable and well-known means, as glue or stitching. Thus constructed the funnel or body is in the form of a hollow truncated cone with the sheet of straining material between the overlying conical walls, forming an inclosure for the liquids. The frail sheet 0, being inclosed between the protecting frames'or sheets of paper A Bone on either side-renders the whole body sufficiently strong and durable for the temporary use and purpose intended, the device thus composed being inexpensive, and a strainer having been once used is discarded and replaced by a new one when other straining is to be done.
In constructing the sections A B to form the body of a strainer it is immaterial and amere matter of convenience whether they are primarily formed in pairs, joined, as shown in Fig. 1, or singly, as shown in Fig. 6. In either case, the sections are all alike and placed one upon another, as stated, in forming the body of the funnel.
With this straining device and as an essential part of the whole I employ a cup or holder D, Fig. 4:, preferably of sheet metal, to receive within it and hold the conical body while in use. This cup is formed with a large central opening is through its bottom plate to avoid the adjacent part of the funnel when in the cup, and the dimensions of the latter and of the funnel are such that the broad band 2' of the latter meets and rests against the upper edge of the cup, as shown. This form and the arrangement of the parts causes all parts of the straining-cloth to be held safely away from the adjacent parts of the cup, and on account of this the cup is not smeared with .any liquid or substance being strained at any time and so may be used indefinitely for straining all kinds of liquids, the funnel only being.
rendered useless and thrown away after being once used.
The holding-cup D is provided with simple wire catches Z Z, Figs. 3, 4, and 7 having their free ends turned inward to meet the upper edge of the funnel when in place in the cup, and also with a yielding spring-catch m, secured to the outer surface of the cup and reaching upward through an opening 72 in the handle 0. These three catches Z Z and m are about equally spaced around the mouth of the cup so as to engage the upper edge of the strainer at three points, the yielding catch m enabling the strainers to be readily inserted into and removed from the cup as they are used.
What I claim as my invention, and desire to secure by Letters Patent, is
1. A device such as described, consisting of a sheet of straining material, as cloth, held between body-sheets, as of paper, placed one upon the other, the body-sheets each having a central opening and a series of openings around the central opening, said central openings' and the openings of the two series being alike in both body-sheets, the sheet of straining material covering all of the openings of both body-sheets, the whole being bent to form an inclosure for the liquid.
2. A device for straining liquids, the same being a truncated conical hollow body formed of two thicknesses or sheets of paper, and a sheet of straining material between the paper sheets, the conical body having openings the body, and a cup or holder for the conical body having an opening through the bottom to clear the adjacent part of the conical body, and catches on the cup for engaging the conical boc y.
4. A device such as described, consisting of a hollow conical body in two overlying parts having openings through its sides, and a sheet of straining material between said outer and inner parts of the body, and a holder for the conical body having an opening at the bottom, and catches on said holder for engaging the upper edge of the conical body,said catches being equally spaced around the conical body, one being elastic and having spring action.
In witness whereof I have hereunto set my hand, this 4th day of May, 1903, in the presence of two subscribing witnesses.
JOSEPH H. ADWEN.
