JAMES sT. EBERT, OF NEW ROCHELLE, NEW YORK.

AUTOMATIC'FUNNEL.

SPECIFICATION forming part 0f Letters Patent NO. 539,422, dated May 21, 1895. y

Application dled December 29, 1894:. Serial No. 533,236. (No model.)

To @ZZ whom it may concern-.-

Be it known that l, JAMES J. EBERT, a citizen of the United States, and a resident of New- Kadapted for sealing theneck of a bottle while the same is being filled; the objects of my'invention being to facilitate the work of filling bottles or other similar vessels, and to prevent overfiow and vconsequent waste of liquid While the same a're being filled. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure l is a vertical section showing my yimproved funnelfitted within the neck of a bottle. Fig. 2 is a side elevation partly broken away. Fig. 3 is a sectional elevation of a portion of a funnel fitted within the neck of a bottle, showing a slightly-modified construction. Fig. 4 is a side 'elevation of a portion of a funnel, partlyin section, showing another modification. Fig. 5 is a sectional elevation of a portion of a funnel, illustratinga further modification.

In the construction of my invention, an ordinary funnel bowl or body A, is provided at its lower or outletportion with a heavy metallic sleeve B, which slides vertically upon a funnel stem C. Within the said funnel stem O, and attached securely thereto is an air tube or vent D, through which the air from a bottle v passes while the same is being filled. This said air tube terminates at its upper end above the top line of the funnel bowl A, and at'its lower end at or near the bottom or outlet portion of the said funnel stem C. rlhe said funnel stem C is also provided with a stop c, adapted to rest upon the sleeve B, of the funnel body A, when the funnel is lifted from the neck of a bottle. Fluid inlet from the funnel body A to the stem C is effected by means of sleeve B, which rests thereon while a bottle is being iilled.

In the practice of' my invention, I prefer the construction as described above and illustrated in Figs. 1, 2, and 3, but it will be readily seen that slight modifications in construction may sometimes be desirable; as forinstance, the bottle closing device E may be ade] ustably securedto the stem C, as illustrated in Fig. 4, in which case, the latter is provided with an exterior thread c2, and the former with a threaded and grooved collar f, adapted to engage with the said thread and to receive the bottlel closing device E.

In Fig. 5, a further modification is shown, in which the bottle closing device E is shown attached directly to the sleeve B, in which case, the stem C must be provided with a collar g, adapted to engage with the neck of a bottle being filled and to prevent the funnel stem from being removed from the body, should the same be inverted.

The operation of my invention is as follows: When the tube or stem C, is inserted within the neck of a bottle to a sufficient distance to allow the bottle closing device E to come in contact with the upper portion of the said bottle neck and rest thereon, the funnel body A, and its sleeve B, will slide downwardly upon the stem C, until the sleeve B shall rest upon the ilange e', of the bottle closing device E, thereby opening the iiuid inlet d, and sealing the neck of the bottle being filled, by bending the said dange e., of the bottle closing device E, over and around the top portion of the bottle; whereby a perfectsealing of the bottle neck is effected without exerting any pressure upon the bottle closing device E, other than that supplied by the oombined weight of the funnel body, its contents and its sleeve B. The liquid is now allowed ICO to flow with perfect freedom until it reaches a level on a line with the lower end of the vent tube D, when further inflow is prevented by the rising liquid closing the vent. The funnel is then removed from the neck of the bottle by the simple act of lifting the funnel body, which slides upwardly upon the t stem C, until its sleeve B comes into engagement with the stop c. The fluid inlet has now been completely shut off, and no further outflow of liquid can be eected until the stem C is again placed within the neck of a bottle. and the funnel body is allowed to drop and open the iuid inlet.

Theoperation as above described applies to the constructions as shown in Figs. 1, 2, 3, and 4, but it will be readily seen that my invention applies equally to the construction as shown in Fig. 5, whereby the sealing of the neck of a bottle is effected by the same means, viz: the pressingof the flange e', of ay bottle` closing` device around and over the` neck of a bottle being filled.

It will be evident to those familiar with the art of filling bottles that my bottle closing device has advantages over any similar device heretofore used in combination with an automatic funnel; as by its use, I not only` eect a perfect sealing of the neck of a bottle, by bending the flange e over and around the neckof same, thereby covering any indentations which may be accidently formed thereon, but I effect such sealing by simply relying upon the pressure exerted by the weight of the funnel body and its sleeve B, thereby obviating the necessity of tightly pressing` the bottle sealing device Within the neck of a bottle, whereby instantaneous removal of the funnel from the bottle is prevented by the bottle closing device adhering to the neck of the bottle.

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

1. In an automatic funnel which comprises in its construction a bowl or body adapted to slide vertically, upon its tube or stem, the combination with a pliable rubber ring mounted upon and projecting outwardly from the said tube or stem, of au annular projec tion upon the lower end of the funnel body, adapted to engage said ring and bend the same over and around the neck of a bottle, substantially as shown and described.

, 2. A funnel tube having connected to it a vertically adjustable bottle closing device, comprising a metallic collar having an annular groove formed thereon, a fiexible ring, Sealed in said annular groove and having a flange formed integrally with said ring, combined with a sliding funnel body, adapted to rest upon the flange ofthe said bottle closing device, for causing the same to seal the neck of a bottle, substantially as shown and described.

3. A bottle closing device comprising a flexible ring having a flange formed thereon, combined with a funnel tube having fluid inlet at its upper part, and a sliding funnel body adapted to rest upon the said bottle closing device, for causing the same to seal the neck of a bottle, substantially as shown and dcscribed.

In testimouy that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 19th day of December, 189i.

JAMES J. EBER'I.
