Threaded to'the portion 2 is a spout consisting of an upper section '3 and'a lower sec: tion 41, said sections'beiug tubular in shape, being spaced ashort distance apart, and being connectedby two or more comparatively I The upper end of the lower section 45is provided with a 'cone-' shaped wall having a centrally disposed opening 7 therein for a purpose to be hereinafterdescribed. ,The upper'section 3 has disposed therein a screen 8 which acts as a strainer when liquid is passing through the funnel. j

Extending transversely across the body'l at the lower end thereof is apartition 9, the latter being soldered orotherwise secured tothewalls of the body and being provided with apertures 10 whioh'are preferably three in number arranged in alinement with one another. Extending transversely'across the body 1 at the upper end thereof and secured 13. Carried by the housing 13 and extending transversely ofthe body- 1 is alplate 15. This plate 15 is disposed'a short distance above the partition 9 and is providedfwith openings .16 arranged directly above the other two openings 10 of the plate 9.

F ulcrumed between its ends intheupper portion of the housing "13 is a lever 17, one

arm or end of which is connected by a rod 18 to a valve 19. This valve 19 isinthe form of a plate which fits tightly against the partition 9 over'the two'end holes 10. This plate is provided witha central opening 20 to provide for the reception of the cylindrical portion 14 of the housing 13. Extending upwardly from the valve plate 19 and projecting through the apertures 16 in the plate 15 are stems 21 which serve to guide the valve plate. The other end or arm of the lever 17 is connected to a rod 22 which extends through the bottom of the body 1 and entirely through both sections of the spout, said rod, extending through the aperture 7 aforementioned whereby it is guided. The lower end-of the to the wall of the same by screws or rivets rod 22 is threaded to provide adjustable mounting for a float 23 which it carries. The float is disposed in the lower section 4; of the spout and has a vertical movement in the same.

The bar 12 is provided with an opening 24, and through this opening projects a handle 25 carried by the lever 17. By means of this handle 25 the lever may be rocked from one position to another to close or open the valve 19. On one side of the housing 13 isdisposed a series of graduations 26. By these graduations 26 the amount of liquid disposed in the funnel may be determined;

The parts are normally in the position shown in Fig. 1 of the drawings, the weight of the float 23 overbalancing the weight of the valve 19 so as to hold the latter in opened position. lVhen the funnel is being used and liquid is being pouredinto the same the valve 19 will remain in its uppermost position to allow the liquid to pass through the openings 10 in the plate 9 and into the upper section 3 of the spout. lVhen the liquid in the receptacle which is being filled rises into engagement with the float 23, the latter will consequently rise and through the medium of the rod 22 will rock the lever 17 so as to close the valve 19 and out off the flow of the liquid. Hence the receptacle will not be filled above a predetermined height. In view of the fact that the float 23 is adjustable upon the rod 22 the automatic closing of the valve may be regulated so that the receptacle may be filled to different heights.

If it is desired to measure a quantity of liquid before allowing the same to pass through the funnel, it is only necessary to engage the operating handle25 and shift the lever 1'? so as to close the valve 19. The

quantity of liquid poured into the body of transversely across said body at the lower end thereof and being provided with a valve seat, a bar extending transversely across said body at the upper end thereof, a housing supported within said body upon said partition and said bar, a valve disposed upon "said seat, a float disposed in said spout, a

lever fulcrumed within said housing, and rods connecting said float and said valve with said lever whereby said valve is closed when said float is occupying its uppermost position.

2. A funnel comprising a body and a spout, said body having a valve seat therein, a housing supported in said body and havingan opening in the upper side thereof, a valve disposed upon said seat, a float disposed in said spout, a lever fulcrumed intermediate of its ends within said housing, rods connecting the opposite ends of said lever with said valve and said float respectively to close said valve when said float is in its uppermost position, and a handle formed integrally with said lever and projecting laterally from the intermediate portion thereof through the opening in said housing, whereby said valve may be manually operated.

3. A funnel comprising an inverted coneshaped body, a spout carried at the lower end of said body, a partition supported within said body and extending transversely across the lower end thereof, said partition being providedrwith a pairof openings therein disposed on opposite sides of the center portion thereof, a housing supported within said body, a plate supported by said housing and spaced a slight distance above said partition, said plate having apertures therein alined with the openings of said partition, a valve plate disposed beneath said plate and movable toward and away fromsaid partition and positioned so as to close the openings therein, guide pins projecting upwardly from said valve plate and extending through the apertures in the first mentioned plate, a float movably mounted in said spout, a lever fulcrumed in said housing, and rods connecting said float and said valve plate with said lever whereby said valve is closed when said float is occupying its uppermost position.

In testimony whereof I have hereunto set my hand.
