To all 7117710717. it 7724/,7 (ion/own.-

Be it known that I, lVILLmM COX, a subject of the I'Cing of Great Britain and inland, and residing at 31 Dcrmcdy road. licwisham, Lcndcn, .lflngland, have invented a c i new and useful Driplrss Spout for T and the Like, of which the following is a specificaticn.

This invention relates to improvements in those capillary devices employed with teapotspcuts, bottlfs, and the like,with the object of preventing a drop of water or other fluid from rolling down the outside of the containing vessel.

The object of the present invention is to provide an improved device of this type applicabl to to acts and the like.

The inven vn consists in providing a capillary passage ceiniminicating with the inteitr' of i the X ssC-l and with the exterior oi the Eli at point bCloW the pouring edge, such that the drop remaining after pouring gravitatrs into the capii v passage.

The invention also comprisfs the improved forms of this device llf rcinafter (lTSC/iliXd, and illus ted in the accoinpanymg drawings, in

wh i e hlfigurcs 1 and 2 are side and front elevations, respectively, cta clawshap1d piece of metal for attachment to the spout or lip of a liquid-ccntainer, Fig. 1 being a section on the line A A oi Fig. 1. Fig. Sis a sectional side (i lieu of a spout, showing a metal claw-pitce attached ther to. Figs. t and. 5 are l'rcnt and side clevaticni-i, rcspmtivrly, of a wire beak l'cr attachmtnt to the spout. Fig. 6 is a stcticn on the line B B of Fig. 5. Fig. 7 is a secticnal view of the spout, showing the beak, according to Figs. 1 and 5, attached the 8 and 9 are sccticn and .l'rcnt view s, respectively, of a t ,i the invcntitn in which the capillary groove is formed in the spout itself.

An essential to this invention is hot from the print whe e the capillary-passage meets namely, to .have gravlty assisting the capilthe exterior of the spent the capillary passage should sink below a horizontal line drawn thrcugh its point of contact with the exterior of the spout. This is CSSCDtiJl, so that the drop gravitatcs into the capillary passage, and its Wt ight thus assists instead of counteracts the cepillinity.

According to one form I provide a suitable attachment to the vcss'il, as shown in Figs. 1 and 2, in which a claw-like or hooked piece of metal 6, having on its inner curve a capillary groove f or a slit,is slipped on the spout, as shown in Fig. 3. The claw-like piece is placed over the edge of the spout or lip and pressed down, its pcint or hooked end 9 tak ing a position and gripping on the under side of the lip of the spout, and thereby catching the drop of liquid which travels to the end 9 and then ilows by means of the capillary passage from the point 9 down the spout into the vessel when the vessel is brought to the upright position or returned to its usual position. It will of course be understood that if the capillary lilm or column of fluid be severed, say, at or near the top of the lip or spout the drop will not be returned down the inside of the spout. It will be seen that the drop gray'itatcs into the capillary passage.

Instead of forming tlc capillary device in the manner above described it may be made of wire bent and arranged for capillary action to take place in tire manner liereinbcfore referred to. Tie wire may be bent to the form slown in Figs. 4 and 5 and passed down the spout, being ltcld in position by the spring-pressure of the wire bearing against as spout. Tito wire is bent double to form a hook or beak h in side elevation, the legs it being spread sli htly to a narrow V form in front elevation. 'lie portions j and j of the wire forming the hook are close together, so t at capillarity may take place wlten tlre wire is wettcd during the pouring out of the liquid, tie capillary passage starting from a point in tic exterior of tie spout below the pouring edge. The mode oi'- operation of this device is practically tlte same as that described wi reference to Figs. 1 and 2; but I 'iind in practice that its operation is better tI'an tie claw-shaped device, and it is the best form at present known to me. In all cases, however, the beak should fall below a horizontal line drawn from the point of contact with tie exterior ol the spout, so as to obtain tie el'l'cct aimed at in this inventionin Figs. 8 and 9, where the spout is formed with a lip or enlarged edge m, in which is provided a curved capillary groove Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A pouring-spout, a capillary passage as sociated therewith into which the drop left after pouring gravitates, said passage leading from a point outside the pouring-spout below the pouring edge to the interior of the spout.

2. A teapot-spout having a member provided with a capillary passage leading from a point below the pouring edge to the interior of the spout said passage being arranged to fall below a horizontal line drawn from its
