SPECIFICATION forming part of Letters Patent No. 453,798, dated June 9, 1891.

Application filed June 23, 1890. Serial No. 356,435. (No model.)

- a citizen of the United States, residing at Bridgeton, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements'in Funnels; and I do hereby declare the following to be a full, elear,and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same. v

Myinvention relates to an improved funnel ot that class in which vents are provided in the nozzle for the escape of air while liquids are being poured through the funnel into a vessel.

My il'iv cntion consists in the combination of a funnel having seats or lugs arranged interiorly within the body thereof and a removable strainer seated within said funnel and having a spring-flange bearing upon the illterior seats or lugs, which operate to hold the strainer against displacement, all as will be hereinafter more fully described and claimed.

To enable others to more readily understand my invention, 1 will now proceed to a v detailed description of the same in connection with the accompanying drawings, in which Figure I is an elevation of the funnel embodying myinvention. Fig. II is a transverse sectional View through the body of the funnel above the joint between the nozzle and body on the plane indicated by the dotted line a: a", of Fig. I. Fig. III is an elevation of my preferred form of funnel having the body' and nozzle made of longitudinal sections. Fig. IV is a vertical sectional view through the funnel shown in Fig. III, and Fig. V is a tran sverse section on the line y y of Fig. III.

Like letters and numerals of reference denote corresponding parts in all the figures of the drawings. f

A designates my imprmed funnel, which comprises the tapered body 1) and the nozzle a. The body and nozzle maybe made of separate pieces and connected together by the.

joint 0 in the ordinary manner; but as a better and cheaper manner of making the funnel I prefer to construct it in longitudinal sections 12 S,which may consist of two, three,

or more, each section forming a part of the body and nozzle of the funnel.

The device constructed as shown in Figs. I and II has its round nozzle flattened on one side to form a vent d, which vent extends longitudinally of the nozzle and into the body Z) to apoint about or above midway of the length of said body, which is advantageous, as it provides for the escape of air should the funnel be placed in a vessel having a mouth of greater diameter than the cross-sectional 'area of the nozzle.

The preferred form of the funnel shown in Figs. III and IV has its nozzle provided with a plurality of flat sides and forming a series of vents, and the nozzle in the cross-section preferably has the forin of a triangle, as shown and described in a prior patent issued to me'February 8,1887, and numbered 357,476.

The sections 1 2 3 of the funnel extend from the top of the body to the lower end of the nozzle, each section forminga part of the body and nozzle. The parts of the section which form the body of the nozzle are each made segmental in cross-section, and the lower parts of said section that form partof the nozzleare flattened. along their side edges through the body of the funnel by bending the same to form flanges and interlocking and soldering the flanges together, thus forming longitudinal seams; but in the nozzle the sections are united by soldering, instead of interlocking the flanges, thus forming continuous smooth seams. The segmental portions of the sections form the body, which is circular in cross-section, and the flattened lower portions of said sections form the triangular nozzle, as shown. The upper end of the funnel is finished and the ends of the joints between the side sections 1 2 3 concealed by an annulus or ring 7, which is bent or curved to extend inward ashort distance.

In connection with my improved funnel I employ a strainer'lO, which is adapted to be fitted within the body of the funnel and to be held therein by means of lugs 11, formed interiorly within the f unn el. In order to provide lugs which shall be sufficiently strong and not easily broken and without weakening the funnel, I stamp or press the lugs through the,

The sections are united together ICO locked scams which unite the sections of the I funnel, and these lugs are preferably tapered and have their lower ends made broad to pro- Vide a bearing-surface against' which the screen impinges or bears. To permit the screen to be readily adjusted or fitted within the funnel below the lugs and to remove the screen when desired, I form recesses 12 (one, two, or more) in the .edge of the screen by indenting or forcing the edge inwardly. The screen can be readily sprung or forced into position within the body of the funnel and below the lugs therein, which lugs operate to firmly secure the same in place; but to remove the screen from the funnel it must be turned so that one of the lugs enters one of the recesses, after which the screen will readily drop out of the funnel when it is inverted, or it can be removed by hand. I

A funnel constructed as contemplated by my present invention can be readily and easily cleaned, as the absence of the joint between the body and nozzle of the funnel provides a smoothsurface, which facilitates the cleaning of the funnel. I

Changes in theform and proportion of parts can be made without departing from the spirit or sacrificing the advantages of my invention, andI would therefore have it understood that I reserve the right to make such modifications as fall within the scope of my invention.

No claim is herein made to the funnel made of longitudinal sections, each section forming a part of the body and nozzle of the funnel and extending from the point of the nozzle to the top of the body, the sections being joined together by longitudinal seams, nor to the nozzle formed with the flattened side or sides, as these features form the subjectanatter of a separate application filed by me on the 19th day of March, 1888, Serial Nov 267,645.

Having thus fully described my invention, whatl claim as new, and desire to secure by Letters Patent, is-

1. In combination with the. funnel having within the intrior of its body the inwardly projecting lugs, a strainer having a springfiange, which is adapted to pass downward over and be locked in place by said lugs, substantially as described.

2. In combination with the funnel provided with the i iwardlyprojecting'loekinglugs, and the strainerhaving a spring-flange, which is thus adapted to pass downward over and to be locked in place by said lugs, and is provided within its edge with notches that when caused to coincide with said lugs will operate to release said strainer and permit of its removal, substantially as herein shown anddescribed.

3. The combination of a funnel provided with the retaining-lugs, which are arranged interiorly within the body of the same, and which lugs are stamped or pressed from the seams which unite the sections of the funnel together, and a "strainer provided with a spring-flange, which is adapted to pass downward over and be locked in place by the said lugs, substantially as and for the purpose drserib'ed.

In testimony whereof I aliix my signature in presence of two witnesses.
