Patented Dec. 15, 1931 UNITED" STATES PATENT OFFIE FUNNEL FOR LIQUIDS Application filed December 26, 1929, Serial No. 416,569, andin Great This invention relates to improvements in filling funnels for liquids of the kind provided, inside the upper end of the outlet or neck of the funnel, with a float-actuated signal for giving an indication when the hotwater bottle, oil lamp or other receptacle with which it is used is full of liquid.

The present invention has more particular reference to funnel fitments of the above kind of the unshrouded type in which a signal and a float are connected, respectively, to the up per and lower ends of a wire which is guided Within the neck of the funnel. Heretofore in I, this type of fitment the wire has been mounted 13 so that it can move only vertically or axially in relation to the funnel, its movement being controlled either by mounting it in a long guide sleeve or else by providing an additional guide at the lower end of the float.

Now according to the present invention I provide a fitment adapted to be'inserted in any shaped funnel for liquids and, in particular, in those funnels the necks of which are tapering, said fitment to be aflixed in the funnel or inserted separately therein as a movable fitment for the purpose of indicating when receptacles for liquids are full, and consisting of a support or cross-bar bracket with a guide-hole therein for the passage of "'a thin rod or wire connecting an indicator, and a narrow float, the said support being so constructed that the iii-poured liquid will impinge direct upon the said float and the diameter of the guide hole being large relatively to that of the rod or wire so that the said float will swing loose with the rod or wire to which it is attached within the neck of the funnel.

In one convenient construction the improved fitment may consist of a cross-bar bracket, a short narrow tube or wire with a guide-hole, a thin rod or wire, a small indicator in the nature of a little flag or ornament, and a narrow float. The said cross-bar bracket has in its centre a hole over which hole the short narrow tube or wire with a ide-hole is fixed to act as a guide to the iiger and give a hole to the fitment and enable it to be slipped in and out of the fun- I101. The said rod or wire passes through Britain February 7, 1929..

the short tube or wire with a guide-hole-and? through the'hole in thesaid cross-bar bracket, the small indicator being at, the upperend of the rod or wire'and the narrow float being at the lower end of the rod or wire. The said hole in the cross-bar bracket is sufficiently large to permit the thin rod or wire which passes through it to swing loose, thus enabling the narrow float attached to the lower end of the rod'or wire to swing loosetoo, whilstthe saidtube' or wire witli'a guidehole, being quite short and of the same diameteras the said hole in the centre of-the cross-bar, bracket, alsopermits of the looseswinging of the rod-or wire and float. By-being narrow this short tube or wire with a guide-hole does not obstruct the liquidwhen it is poured into the funneli The cross-barsof the said bracket are quite narrow and'thin to enable the iii-poured liquid to impinge direct on the float and pass unimpeded'into-the funnelneck and receptacle. Onecross-barof the bracket is bent in a downward direction at its extremities to enable the fitment to A grip the inner sides of: the upper end of' the narrow outlet or neck of the funnel from where it can be removed andreplaced as desired, or in which it can be thus fixed per manent'ly. When the said fitment is inp0-- sition the small indicator restsonthe top-of so the-short tube or wire with a guid'e-hole-immediately above the funnel-neck or outlet. The saidfloat by being narrow'can be insert-- ed in any shaped funnel forliqnids and,in particular, in those funnels the necks of which are tapered, the narrowness of the float also enables it to have freedomof action with the rodor wire to which it is attached when swinging loose within the neck of the 4 funnel. The said indicator prevents thesaid rod' or wire from falling through the short tube or wire with a guide-holein the said cross-bar bracket.

In the functioning of the fitment thefunnel is placed in the opening inthe receptacle and the liquid is poured; into the funnel: This liquidimpingeson the float and, pushingit down, automatically adjusts it. To ascertain whenthe receptacle is full an occa sional pause inthe pouring-in of theliquid is made when, if the liquid has risen sufiieter of the neck whereby it may rock freely ciently high in the receptacle to begin to enter in the neck and greater than the diameter of the funnel-neck, the float rises and slightly the guide ring whereby it may abut the under pushes up the small indicator. When the side of the ring. 5 liquid has penetrated sufliciently into the In witness whereof I have hereunto signed 7 funnel-neck from the inside of the receptacle my name. and a further pause in the pouring-in of the DOROTHY BLANCHE MILLER. liquid is made, the float agan rises and, by reason of its buoyancy and the fact that it is 10 loose-swinging, shoots or bobs up and strikes 75 the cross-barw bracket, which final rise at the float and indicator signifies that the receptacle is full.

The present invention is more particularly 7 1 described with reference to the accompany- 80 ing drawings, in which Figure 1 is a perspective view of the crossbar bracket portion of the fitment; and

Figure 2 is a sectional side elevation show- 9; ing the fitment applied to a funnel inserted 85 in the neck of a hot-water bottle.

As shown, the reference letter A indicates the funnel and F a hot-water bottle. The cross-bar bracket D (Figure 1) has in its centre a hole C over which is afiixed the short I 90 narrow tube T. The reference letter H indicates the thin rod or wire, whilst B indicates the indicator which, when in its lowest position, rests on the top of the tube T just above the outlet or neck of the funnel. E indicates 95 the narrow float.

The float E, being narrow and swinging loose, does not interfere with the pouring-in of the liquid, but the funnel outlet could, if desired, be expanded to expedite the filling 100 of the receptacle. 7

What I claim is 1. An attachment for funnels comprising a bracke to fit in the funnel at the upper end 40 of the neck thereof, said bracket providing '105 large open spaces for the flow of a liquid and provided at its center with a guide opening and a short tube around said opening, a float, an indicator, and a stem passing loosely through the central guide opening in the 11o bracket whereby it may rock in said opening, the float being secured to the lower end of the stem to be housed in the neck of the funnel and rock freely therein, and the indicator being secured on the upper end of the stem 1 above the bracket.

2. An attachment for funnels comprising a bracket to flt in the funnel at the upper end of the neck thereof and consisting of wires disposed in angular relation, the outer ends of some of the wires being turned downwardly and a guide ring connecting the inner ends of the wires, a stem passing loosely v through the guide ring, an indicator on the 60 upper end of the stem of greater diameter Q than the guide ring adapted at'times to rest on the guide ring, and a float depending from the lower end of the stemto be housed in the neck of the funnel, the diameter of the 5 float being appreciably less than the diaml3:
