r' Referring to theadcoinpanying drawing ..by numerals it will be, seen that the funnel comprisesthe usual flared upper end I hav ing the spout 2 fixedly mounted upon and 55. extending from the lower; portions thereof. The flared end 1 may be'provided with a ring 3 which will allow the same to be carried from place to place or supported as desired.v i t A band 4 is mounted upon the spout 2 adjacent its lower end, while a supporting bracket '5, is carried upon the spout 2 adjacent the flared end 1 0f the tunnel. The :band 4 has the parallel extensions 6 between which the bell'crank lever 7& mounted so as [tob epivotally secured bymeans of the pins, Aflat plate 9 is formed integral upon the bell crank lever 7 and it isadapted to support the leather washer 10 by means of the rivet 11. This bell. crank lever 7 is mounted upon the extensions 6 of the band 4:,.-.sothat whenswung in one direction the plateQ :willhold the leather Washer in firm engagement with thelower end of the spout 2 for, preventing the passage of liquid throughthe funnel.

The bracket Shae an elongated U-shaped portion 12, and in, this U-shaped portion 12 there extendsthe operating rod 13. This rod 13 is bifurcated at its lower end, as shown at 14, so as to embrace the bell crank l i er 7 whereby a pivotv pin 15 may be passed through the bell crank. lever and through the bifurcated end so as to pivotally secure 'the rod to the bell crank, lever. An abut- .ment washer 16 is positioned upon the rod 13-and against this abutment washer 16 the coiled spring 17 is adapted to bear. It will .1 be seen that this coiled spring is positioned upon the rod13 and bearsat one end, as hereinbefore set forth,'upon,the washer 16 ndat its oppositeend; upon the shoulder portion 18 of the rod 13. This action of thespring will hold the washer 16 in en- ;gagement'with the U-shaped portion 12 of the bracket 5, and will, therefore, exert a ;downward pressure upon the rod 13. The rod will in turn exert a downward pressure upon one end of the bellcrank lever so as to normally cause this lever to swing the washer 10 into engagement with the lower end of the spout 2' for cutting off the passage of liquid through the funnel. The up- ;per end of the rod 13 is provided with an aperture 19 so asto receive the ring 20,

whereby when so desired the rod 13 may be pulled upwardly for compressing the spring and swinging the bell cranklever for mov- '1 ingthe leather Washer 10 c from engagement with the spent 2;

In order to 'retai'nthis rod in a setposi- ,-',tion while a vessel'is being filled a trigger a 21 is provided which passes through the opening 22 formed in the. block 23. This block 23 has the tongues 24: extending from its side edges, and this block is carriedbetween the side portions of the U-shaped portion 12 of thehracket 5. The tongues 2% are passed through the U-shaped portion and in this manner support the block 23. It will be noted that this block 23 is held in a slanting position of approximately -l5, and will in this manner cause the trigger 21 to eX- tend at this angle also. This trigger 21 is provided with a head 25 at its inner end, and against this head the coiled spring 26 carried upon the trigger 21 will bear. The opposite end of the coiled spring, however, will bear upon the block 23 and will in this -manner normally urge the trigger 21 in one direction. The outer end of the trigger 21 is pointed, as shown at 2'7, and is adapted to fit within one of the notches 28 formed upon one side of the rod 13. As long as this trigger member 21 remains in a position so as to hold the pointed end 27 within one of the notches 28 it will be seen that the rod 13 will be held as shown in Fig. 2, so as to allow the bell crank lever to retain the washer 10 from engagement with the spout thereby liquid may be passed through the funnel.

lln order to retain this trigger in its position for retaining the coiled spring, compressed while the operating elements are in a set position av yoke 29 is passed through the trigger 21 and has its end portions 30 journaled to the side portions of the U- shaped portion 12 of the bracket 5. A finger 31 extends from one of the ends 30 and terminates in an eye 32 to which the eye 33 of the float strand 34 is secured. The float 35 is slidably mounted upon the float strand 34, which is adapted to fit so snugly upon the float strand 3% as to pr vent its accidentally slipping along this strand. Beneath this float 35 and upon the lower end of the strand there is carried a weight 36. This float strand 34; passes through the guide link 37" which has its inner portions bent to form the pivot pin 15. In this manner it will be seen that the float strand will he held from swinging from side to side when liquid comes into engagement with the float 35 and, there fore, an upward pressure will be exerted upon the strand 3%. This action will cause the strand to swing the outer end of the finger 31 upwardly and therefore will cause the ends 30 of the yoke to pivot for swinging the yoke outwardly. This action upon the part of the yoke will move the trigger 21 from engagement with the rod 13 and will, therefore, allow the spring 17 of the rod to swing the leather washer by means of the bell crank lever into engage ment with the spout "for cutting 01% the dew of liquid. It will be noted that the spring 26 will also urge the trigger 21 inwardly, but it is intended that the strength or resiliency of the spring 26 will counteract the retarding action of the weight 36. It will be seen that by the use of the weight 36 and the spring 26 the trigger member may be more readily set than if the same were not used.

A sleeve is mounted upon the flared end 1 of the funnel and comprises a primary section 37 and an auxiliary section 38. The primary section is. soldered, as Shown at 39 to the flared end 1 of the tunnel and is provided with a plurality of depending slots 40. The auxiliary section 38 is provided withupwardly extending :slots &1 and through these slots there extend the adjusting bolts 12. When so desired, the bolts may be loosened so as to allow the section 38 to slide upon the section 371, thereby allowing the section 38 to extend downwardly for a. considerable distance. When the funnel is in use, the section 38 may be positioned upon the receptacle being filled, thereby supporting the tunnel for preventing any'of the supporting strain to be imparted to the operating mechanism of the funnel. In this way the operating mechanism is free to operate. without inter ference. It will, of course, be noted that the

sections

37 and 38 are cut away from their side portions adjacent the operating elements of the funnel, as clearly shown in Fig. 1 so as to allow these elements to elliciently. operate when necessary.

From the foregoing description it will be seen that a very simple and eflieient funnel has been provided which may be set by the moving upwardly of the rod 13 by pulling upon the ring 20. At this time the'fioat strand 3 may be urged downwardly so as to *cause the finger 31 to swing the yoke 29 for moving the trigger 21 into engagement with the rod 13 so as to rest withinone of the notches 28. At this time the passage through the spout 2 will be unobstructed. The tunnel may then be positioned so as to allow the spout to extend into a vessel "to be filled and the liquid may then be passed into the funnel. As the liquid begins to rise within the vessel it may continue to do so until it comes into engagement with the float 35. The force uponthe float, however, will cause the same to lift the rod for swinging the yoke by means of the finger as hereinbetore set forth. This action will cause the trigger to disengage the rod and allow the rod to cause the bell cranklever to swing the washer 10 into engagement with the lower end of the spout 2 so as to prevent the further passage of liquid into the vessel.

From the foregoing description it will he seen that a very simple and eflicient tunnel has been provided which will remain in a set position when desired, but which will operate for cutting off the flow of the liq uid therefrom when it is desired to prevent the over-filling or over-flowing of the vessel into which the liquid is being dispensed.

What is claimed is:

In a device of the class described the combination of a funnel having a closure means, a bell crank lever connected to said means, a spring pressed rod connected to said bell crank lever, whereby said rod will be normally urged in one direction, a bracket provided with a U-shaped portion mounted upon said funnel, a spring pressed trigger mounted upon said bracket and releasably engaging said rod, a yoke pivotally supported upon said U-shaped portion of the bracket and engaging said trigger, a finger extending from said yoke, a float strand connected to said finger, a float mounted upon said strand, whereby when said rod is lifted by said float, said finger will swing said yoke, causing said trigger to be moved from engagement with said rod, whereby said rod will swing said bell crank lever for moving said closure means to a closed position and at a predetermined time.

In testimony whereof I hereunto afiix my signature.
