To all whom t may concern.' l

Be it known that I, FREDERICK LIQUORISH, a subject of the King of Great Britain, and resident of 71 Laurel road, Leicester, England, have invented certain new and useful Improvements in or Relating to Spouts or Pouring Devices for Petrol-Cans and the I Jike, of which the following is a specification.

This invention relates to spouts or pouring devices more particularly designed for expeditiously transferring liquids such as petrol and the like from cans or containers into the storage tanks of motor vehicles and the like.

The invention refers to the type of spout comprising a tube adapted to be temporarily. attached to the usual screwed neck or'nozzle fitted to an ordinary can or container.

In further describing the invention reference will be made to the accompanying drawing wherein'- y Figure 1 is an exterior View of the spout. Fig.- 2 is a longitudinal sect-ion of the same. Fig. 3 is a cross section taken on the line a-a of Fig. 2.

The spout of the present invention consists of a tapering tube 1, the largest end 2 of said tube being approximately straight while the smaller or outlet end 3 is bentlor curved as shown in Figs. 1 and 2. The larger end 2 of the spout is adapted to be temporarily attached to the usual nozzle or neck on the can or container and for this purpose said larger end is provided with a union 4 by which the spout may be screwed to said nozzle. This union or coupling 4 is preferably screw-threaded attwo different diameters 5 and 6 so that the spout may be applied to varying sizes of can necks or nozzles. The union may be of `any other suitable typeadapted toclasp or otherwise"l attach the spout to a can. n

Formed through the top ofthe tube 1 and located at or near the larger end 2 of same is a vent hole 7 which permits the entrance of air into the can when the spirit is being poured out. By preference one vent is provided band this is located in close proximitav to the connecting coupling 4 so as to admit the air as near as 'possible to thec'an. The interior of the top of the spout where the vent is formed may or may not be, but preferably is, fiuted or channeled longitudinally at 8 (Figs. 2 and 3) so that as the spiritl or liquid lows through the spout the air passes along the channel in an opposite direction t0 replace the liquid in the can.,

In the operation of the spout, the r`entrance of air through the venthole 7 prevents leakage of thc spirit or liquid through `said hole, and a fcor or partition 9 is lobular body 1 in -any convenient manner and extends along the straight and wide portion 2 only of the tube, thus leaving the narrower bent or delivery -end of the spout of the full area for the flow of t-he spirit therethrough. rlhe fioor is open at both ends so that in the eventy of any of the liquid passing on to the top of the floor into the air passage, such liquid inay'run along the upper side of the fioor and pass off the forward end thereof to rejoin the liquid fiowing through the spout underneath the floor. Should the spout be fiooded above the floor orpartition 9, then the channeled or fluted interior 8 of the spout will still provide an inlet passage above the liquid for the air.

In use, the pouring device is screwed directly on to the container and as soon as the latter is tipped over the liquid will pass out through the lower passage 11 and filtering screen 14. The vliquid will, however, only flow so long as air is admitted into the container, which air (under normal circumstances) passes into the container through the vent. hole`7 and upper passage 10. The floor 9 Yis employed for the twofold purpose of separating the irl-'going current of air from the outgoing `stream of liquid and of preyenting the liquid from passing out "through the vent hole 7. When the con-A tainer is first inclined a small amount of liquid may'pass through the upper passage, but as soon as .normal conditions are reached, the in-going air will prevent furthier quantities of water from passing through the upper channel. Furthermore, the floor 9 extends along the upper part of the device for a distance sufficient to prevent any liquid from returning through the upper passage and of escaping through the vent hole. The object of the fluted portion '8 is to increase the cross-sectional area of the upper passage so as to allow the in-going air to pass into' the container should said passage become partially flooded during the preliminary stages of the pouring operation. The vent hole 7 may be covered by a rose or perforated dome or-cap 12 on the exterior of the tube 1 and the small or outlet end 3 of the spout may be provided with a detachable screwed ring 13 or equivalent means adapted to hold a filtering' sci'een 14 over said outlet end to iltelor strain the liquid as it passes therethrough. l

The filtering screen may consist of a dlsk 14 of gauze or the like. j

The spoilt may be furnished on the outside near the oiit-letend 3 with a lip 15 or similar projection so that yWhen the spout is in use said lip or the like may be rested on the tank. The said projection is located preferably a. little distance from the outlet end so that the latterwill project a short distance in the tank. When the level of the 'spirit or liquid in the tank rises above the outlet end of the spout the sound caused by the falling liquid will cease and it may be thereby ascertained that the tank has re-` ceived Va suflicient quantity. By this arrangement the' spout may be employed to lill a tank in the dark.

Claims.

1. A spout or pouring Adevice comprising a tube provided with an air inlet at its rear end and a partition in said tube also at its rear end and extending beneath said airinlet, said lpartition being shorter than said tube-and dividing the interior thereof into two 'relatively short 'channels and a common ,outlet channel, said short channels communicating, at their exit ends, with said outlet channel and said partition being sulfi-` cie-ntly short to cause the air which passes over it to pass around its front end and beneath it to the rear ofthe spout.

2. A spout or pouring device comprising a tube provided with an air inlet at its rear .end and a longitudinal recess projecting outwardly beyond the inner surface of said FREDERICK LIQUORISH.
