FUNNEL.

Specification of Letters Patent.

Patented May 20, 1919.

' Application filed July 30, 1917 Serial No. 183,572.

To all whom it may'cohcerh:

Be it known that I, FLoYo I-I; GUSTAFS N,

a citizen of the United States,and residing at Mead, in the county I of-S'aunders and State of Nebraska, have invented certain new and-useful Improvemen-ts in-Funnels, of which the following is a specification' My invention relates to funnels, and more particularly to self-closing funnels, adapted to be used in filling receptacles, and which will close, or cut off the supply of liquid from the funnel, when the receptacle becomes filled.

An object of my invention is to provide a device of the above mentioned character which will automatically close and cut ofi' the supply of liquid to the receptacle when the receptacle is filled.

Another object of my invention is to provide a device of the above mentioned character which may be closed and raised from the receptacle by the same operation.

A further object of my invention is to provide a device of the above mentioned character having associated therewith a valve rod provided with a stop, to prevent the downward vertical movement of the same after the valve has descended to its open position.

A still further object of my invention is to provide a device of the above mentioned character which is strong and durable, inexpensive to manufacture, and easy to operate.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming part of the description, and wherein like numerals are employed to designate .llke

parts throughout the same,

Figure 1, is a vertical sectional view of the device.

Fig. 2, is an enlarged sectional view looking down into the funnel, and is taken on line 2-2 of Fig. 1.

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 1, designates the funnel of the ordinary type and is provided with the usual spout 2. Arranged in the funnel above the spout is a plate, or valve seat 3, which is circular, and is provided with ears or tabs 4. This valve seat is also provided with a central opening 5,

said opening being bridged by a piece of material 6, which is provided with an opening inthe-center thereof to form a guide for the valve rod 7 The valverod is provided with a finger ring 8, at the top end thereof, and is also provided with a flattened portion -.9, the purpose of which will be hereinafter set forth. Arranged upon the lower end of this valve rod is a valve 10, which is preferably formed of cork. The body portion 1, of this funnel is provided with splits or openings adapted to receive the ears or tabs 4: of the valve seat. After these cars have been inserted through said openings they are bent up and lie flush with the outside of the funnel. The flattened portion 9 of the valve rod 7 is arranged ashort distance above the valve 10, in order that the valve 10, when in lowermost position, will not engage the walls of the spout. These constructions are necessary, in that, when the liquid is permitted to flow from the body portion, into the spout 2, through the openings 5, the liquid will have a free passage around the valve 10.

In use the spout of the funnel is inserted into the receptacle to be filled. It will be seen that the weight of the valve rod will carry the same downward until the flattened portion thereof, comes into engagement with the edges of the central opening in the bridging member 6. When in this position the liquid is then poured into the body portion of the funnel and is permitted to run through the openings 5, around the valve 10, down the spout and into the receptacle. In the spout 2, the buoyant valve will begin to rise with the water level and the valve 10 will be forced against the under side of said valve seat, thereby closing the openings 5 and cutting off the supply of liquid into the receptacle. The forefinger of the users hand is then inserted through the finger ring 8 of the valv e rod, and the funnel is then lifted from the receptacle. By raising the funnel in this manner, it will be seen that the valve 10 is in close engagement with the under side of the valve seat 3 thereby keeping the surplus liquid in the upper part of the funnel.

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that various changes in shape, size, and arrangement of parts may be resorted towithout'departing from spirit of the invention or the scope of the-subjoined claim.

. Having thus described my invention, what body part and spout and having a central opening, said plate being of the same diametrical size as the portion-of the body part to which it is secured whereby theplate spans the opening to the funnel, a bridging strip spanning'said central opening and" provided with: a central apertur a: valve rod s cured to the lower end of said rod for engagement with theunderside of said valve 29 plate for closing the central openingtherein. In testimony whereof I afiix my signature in presence of two witnesses.
