ROBERT L. MoGQY, OF SERGEANTS BLUFF, IOWA.

FUNNEL.

Application filed October 18, 1.913.

To all whom it may concern:

Be it known that I, ROBERT L. MoOoY, a citizen of the United States, residing at bergeants Blufii, in the county of VVoodbury and State of Iowa, have invented certain new and useful Improvements in Funnels, of which the following is a specification.

This invention relates to funnels of that type in which suitable means are associated therewith for cutting ofl communication between the funnel and the receptacle with which the funnel is engaged as soon as a predetermined height in the receptacle has been reached.

An object of this invention resides in the provision of a device which may be advantageously used with the ordinary type of funnel now in use although a funnel having a straight discharge spout is preferable in view of the fact that a straight spout will allow for the float to extend into the vessel a suflicient distance to cause it to rise with the liquid and at the same time prevent the float from binding in the spout as is very often the case where a device of this character is used with a tapering spout.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring to the drawings Figure 1 is a longitudinal sectional view of a funnel constructed in accordance with my invention;

Fig. 2 is a detail fragmentary view showing the valve used in the present invention in a closed position; and

Fig. 3 is a detail longitudinal sectional view of the float used in the present invention.

In the drawings wherein is illustrated the preferred embodiment of this invention, a funnel 5 is provided which is of the ordinary inverted cone-shaped type having issuing from the apex thereof a suitable discharge nozzle or spout 6 which in the present instance is of a uniform diameter throughout its length for a purpose which will subsequently appear. Mounted in the funnel 5 adjacent the apex thereof, is a plate 7 which is preferably of a circular configuration conforming to the configuration of the inner periphery of the funnel, having an Specification of Letters Patent.

opening formed in the center thereof and a valve opening 8 arranged between said central opening and the inner periphery of said funnel.

Goncentrically mounted in the spout 6 and extending upwardly into engagement with the plate 7 is an elongated cylindrical housing 9 the one end 10 of which is open and the opposite end partly closed by a flange 11, said end 11 snugly engaging with the lower or inner face of the plate 7 and being provided with a central opening in which is engaged one end 12 of the tube 13, said tube 13 being likewise of a cylindrical configuration but of a diameter smaller than that of the diameter of the housing 9. The end 12 of the tube 13 is flared outwardly and lies in engagement with the inner face of the upper end 11 of said housing 9, while a portion of said tube adjacent the flared end 12 thereof isdepressed outwardly as indicated at 14 providing an annular flange which engages with the upper face of the plate 7 adjacent the central opening thereof through which the tube 13 extends. Upon reference to Fig. 1 of the drawings it is seen that the tube 13 extends upwardly to a point adjacent the upper marginal edge of the funnel 5 serving not only as an air tube for emitting air coming from the receptacle which is being filled but at the same time providing a guard for facilitating the operation of the float rod 15 which is mounted therein.

Fixedly mounted on the one end of the rod 15, is a float 16 which in the present instance is-formed of sheet metal and is preferably of a cylindrical configuration conforming to the contour of the inner periphery of the housing 9 in which said float is slidably mounted, the opposite end of said rod 14: extending beyond the upper end of the tube 13. Fixedly engaged with the rod 15 adj a cent its upper end is a strap 17 pivotally engaged with a rock shaft 18, said shaft extending through an opening 18 in the housing 9 and having engagement approximately midway its ends with a depending finger or arm 19 the latter extending from the inner face of the plate 7 Pivotally engaged with the opposite end of said rod'18 is a valve rod 20 which has mounted on the upper end thereof a valve 21, said valve rod extending through the opening 8, said valve 21 adapted to close said opening when the float 16 is elevated in the housing 9.

In operation the spout or discharge nozzle 6 of the funnel 5 is placed in a receptacle in the usual manner, and the float 16 arranged in the housing 9 in a position as shown in Fig. 1, in which position the valve 21 will be disengaged from its seat, thereby establishing communication through the opening 8 of the plate 7 and hence through the spout 6 of the funnel. The liquid is poured into the funnel 5 and allowed to flow through the opening 8 and through the spout 6 into the receptacle which is associated with said spout, in the ordinary manner. As soon as a predetermined height has been reached in the vessel, the float 16 will be ope 'ated in the housing 9 in a vertical or longitudinal direction causing the shaft 18 to be rocked for closing said valve 21 on its seat, so as to disconnect or close communication between the funnel and the receptacle, any surplus liquid being held in the funnel can be readily dispensed therefrom into the supply tank if so desired. To dispense the surplus liquid the upper extremity of the rod 15 is depressed-and the contents may thus be allowed to flow from the funnel. To maintain the valve 21 in closed position the extension of the rod 15 is grasped by the attendant and a slight pull imparted thereto, consequently, securely holding the valve to its seat through the medium of the rock shaft 18 and the valve rod 20. During the operating of the float 16 in the housing 9 air coming from the receptacle which is being filled will be allowed to escape through the housing 9 and tube 13 so as to in no way prevent the free operation of the device. In order to open the valve 21 when it is desired to again use the funnel pressure is exerted on the upper end of the rod 15 causing the float 16 to again take the position as shown in Fig. 1.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in details of construction, proportion and arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is 1. In an automatic funnel, a valve arranged in the body of said funnel, a concentric float housing in the spout of the funnel, a float movable in the housing, means for connecting the float with the valve for closing the same at predetermined periods,

and an air tube arranged concentrically of the funnel and the housing and communicating with and secured to said housing, said connecting means extending through the air tube and above the same to facilitate the gripping of the same for holding the valve in a closed position.

2. In combination with a funnel having a spout, a plate fixedly arranged in said funnel adjacent the apex end thereof, said plate provided with a central opening therein and an opening adjacent said central opening, a housing concentrically mounted in said spout and extending upwardly therethrough ii'ito'engagement with the inner face of said plate, an air tube passing through the central opening of said plate and having engagement with the upper end of said housing, a float operatively mounted in said concentric housing, the upper end thereof ex tending through said air tube, and a valve engaging over said second mentioned opening and having connection with said float as and for the purpose set forth.

3. The combination with a funnel having a. spout, said spout being of a uniform diameter throughout its length, a plate fixedly carried in said funnel in proximity of the apex end thereof, said plate provided with a concentric and an eccentric opening, an elongated cylindrical housing concentrically mounted in said spout, one end thereof being partly closed and the opposite end open, said partly closed end extending upwardly through said spout and into engagement with the inner face of said plate, an air tube centrally mounted in the funnel, the one end thereof extending through the concentric opening and having engagement with the partly closed end of the housin a float movably mounted in said housing, a rod, the one end of which is in engagement with said float and the opposite end extending through said air tube to a point above the same to facilitate gripping thereof, a rock shaft fulcrumed at a point eccentric on said plate, the one end being in engagement with said float rod, and a valve closure pivotally carried by the opposite end of said shaft for closing said eccentric opening when the float is operated, as and for the purpose set forth.

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

ROBERT L. MOCOY.
