This invention relates to a can pouring spout and has for an object to provide a can pouring spout which may be attached to and through the outlet of a can containing a liquid such as may be used in a household or a garage.

A further object of this invention is to provide an attachable and detachable can pouring spout which may be attached to and detached from cans such as one or five gallon cans, or even smaller ones, such as used in households for fruit juices or other liquids irrespective of Whether the can is initially provided with a prearranged outlet or whether the can is adapted to have outlet holes punched therein as by a nail or awl. v

A further object of this invention is to provide a can pouring spout which may be attached to a canat any location at which there may be an existing outlet, or at which it may be desired to form an outlet.

Afurther object of this invention is to provide an attachable can pouring spout which has a closeable lid whereby the contents of the can may (be temporarily sealed against evaporation or contamination While the spout is left in attached position.

A further object of this invention is to provide an attachable spout which may be detached from the can and readily 1re-attached to the same or another can without necessitating the use of tools.

With the foregoing and other objects in View as will hereinafter become apparent, this invention comprises the constructions, combinations, and arrangement of parts hereinafter set forth, disclosed and shown on the accompanying drawings. In these drawings:

Fig. 4 is a sectional view on line 4 3 of Fig. 3.

Fig. 5 is a view similar to Fig. 3, showing. a

different form of attaching means especially suitable where there is a large preeformecl opening of this invention.

Figs. 9, 10 and l1 are section views on lines 9 9, IG-ID and II-II ofFig. 8. f

There is shown at I0 a representation of a can of any size such as generallyr used for liquids of any nature whether oil, `gasoline,`or home supplies. As here shown, the can ID has had' a pair of holes I2 and I3 punched in diagonally opposite corners thereof, one. hole I2 serving as a liquid outlet, while the otherhole I3 acts as an air hole. f

The spout Hl of this invention consists ci an y elongated funnel-shaped member i5 having a pouring gauge I6 depressed'sbetween the opposite side walls Il. A lid vI8 is hinged as rat I to the back wall 25 of the spout and is provided at its forward end with a depending spring tip 2l adapted, in closed position, to extend beneath the pouring lip l@ as shown in Fig. 3, to hold the lid I8 in closed position. The inside of the lid I8 may be provided with a gasket member 22 which may cooperate with the edges of the walls of the spout to seal the same when in closed position.

The bottom of the spout has a horizontal fioor 23 through which extends the opening 26 for the liquid II to enter from the opening I2 of the can iii. A perforated gasket 25 is secured to the bottom of the fioor 24 by any suitable cement so that when the spout I4 is secured to the can I by any one of thefastening means hereinafter described, the gasket 25 serves to prevent leakage between the spout and the can, and insures that the liquid II will flow through the spout I to the pouring lip I6.

In the form of the invention shown in Figs. 2, Sand 4, the fastening means for securing the spout on the can consists of a comparatively small boring screw 26 terminating in avertical stem 21 which ends in a nger loop 28. Surrounding this boring screw 2B is a spiral-shaped spring 30 having a large end 3i of a diameter somewhat larger than the opening. 2d in the spout floor 23, while its smaller end 32' wound about the stem 2T of the boring screw 2t.

In operation,the spout I d is placed over any suitably located pouringhole IZpin the can Hl. With the lid 2| in raised position, the boring screw 26 is inserted through the hole 24 of the spout floor 23 through the hole in the gasket 25 and threaded through the opening I2 in the can I 0 to bring it to the position shown in Fig. 3, the diameter of the screw portion of the boring screw 26 being greater than the diameter of the opening I2, so that one of the whirlsv of the 'spring 2s win extend beneath the edge er the opening I2 in the can I0.

It wiii be noted from Fig. 2 that the iehgth of the spiral spring is substantially equal to the length of the boring'screw 26", and as above noted the diameter'of the end 3| of the spring 36 is the spiral spring 30 will be comparativelyyie'ld--.

sisting of a pair of parallel arms 56 fastened together by a tie member 51 having oppositelyV extending fingers 58 above the cap 54. The lower ends of the arms 56 are provided with spring coils 60 and have upwardly and outwardly extending f legs 6| somewhat similar to the construction of the conventional safety pin. The upward ends of the legs 6i have inwardly turned feet 62 endable. As a result thereof, it will be obvious that I. the spiral spring 30 under compression will 'push the floor 23 of the spout I4 downwardly against the gasket 25, and thus against the top ofthe can I0 while the boring screw 26- will hold itinV this position against accidental separation.

To pour thecontents of liquid il imm the can 16 the spring top 2l of lid Il willbe `pulled forwardly by ones nger, permitting the lid yIB to be raised and the, liquid to be poured `from the opening I2, the spoutfioor opening 24, and out through the pouring lip i6. If only part of the contents'of the can `lll are to be used, the lidflS :may be closed and held in :closed position by the spring top 2|, thus preventing the evaporation -or contamination of the liquid through the pouring hole while any other suitable means may be used to close the air hole I3.

@In Figs. 5, 6 and '1 the invention'is shown lasy applied toa can 35 having a pre-formed threaded openingv 36 of a .substantial diameter `that is greater than the diameter of the opening such as I2, as formed by a punch or an awl. In this form, the spout 31 is identical in construction with the spout i4. The difference between this l :form of the invention and the formalready described is substantially in the fastening means alone. The fastening means in this form consists of ra spider 38 having a roof 39 provided with depending legs 40 terminating in feetu4l so spaced that they will abut on the top of the floor 23 of the spoutv31. A coiled spring `i12 has arms 43 extending through perforations` 44 in the spider roof n 39 and terminating in outwardly flared feet 45. i y v In operation, .the spider feet 4l may =or may not bepermanently secured to the floor l,23,Vas desired.` In either case, to attach the spout V31 to a can 35 having apre-formed opening 36 `of substantial size, the arms 43 .are pressed toward eachother by ones ingers which may pass between the spider legs to hold the coiled ,spring 3 outwardly flared legs 45 sufficiently close together so that 'they may pass through the aperture in the pre-formed opening 36. Whens uiiic'iently` far inthey are released and vthen will extend ing in upturned toes 63. Also extending down through the cap 54 between the arms 56 is a releasing device consisting of a linger loop 64 having a stem 65 slidably passing through the tie member 51 and secured to a second and slidable tie memberl 66. Also secured to this tie ,member 66 is a. loop 61 extending around both legs 6I, the diameter of loop 61 being at least slightly less than the diameter of the opening through the pre-formed can outlet 36.

y To attach the spout in operative position it is only necessary to push the arms 56 through the opening 23 of .the floor spout 52 and then through the gasket 5I :and opening in the preformed outlet 36'. The :legs 61 will yield in VWardiy due to their coiled springs'l! until the feet 62 are beneaththeidges of lthe opening ofl the outlet 36'A and will be 'heldin this position against further expansion byV the upwardly .extendmg toes 63, thuslockingthe spout in oper ative position. To release the spout when desired, the finger loop 64 is grasped Aand raised vertically causing the releaser loop .61 to bend the Vieee si toward eachother, withdrawing the feet V62 from beneath `the redges of the .opening until they canv pass through the opening, .thereby detaching the spout. The compression spring 153;

serves to hold the spout 5,0 in operative position below the edges of the perforation underneath the top of the can 35 Vholding the spout 31lin operative position just as in the previous form Inthe spout 50, shown in Figs. 8 to ll inclusive, the details of the `spout are substantially fidentical except that the gasket 5l beneath the spout floor 52 is shown as somewhat vlar-ger so that it may take care -of :pre-formed-Ycan "holes '56 -of varying diameters. u

In this form a compression coiled spring ,53 iis i vprovided beneath va cap 54 with ione endl Iof the through the cap 54 is a locking @device 155 con-f and at the same time serves -to keep the cap M Vsufficiently spaced from the spout door` 52 so .that

the liquid .Il in the :can my pourvfrieely therefrom.
