v. DIEU POURING SPOUT Filed Sept. 6. 1922 S M m w W Victor Dz'cu A TTOR/VE VS Patented Dec. 4, 1923.
UNITED STATES VICTOR DIEU, OF MINERAL WELLS, TEXAS.
Application filed September'6, 1922. Serial No. 586,487.
To all whom may concern:
Be it known that L VICTOR Dino, a. citizen of the United States, and a resident of Mineral Wells, in the county of Palo Pinto and State of Texas, have invented certain new and useful Improvements in Pouring Spouts, of which the following is a specification.
My invention relates to improvements in pouring spouts and it consists substantially of the construction, combination and arrangement herein described and claimed.
An object of the invention is to provide a spout for pouring milk and other liquids from tin and other cans, suchspout comprising the combination of a puncturing'head which has integral fluid and air passages, the only operation required for its application being to push the head into the tin and give it a quarter turn.
Other objects and advantages will appear in the following specification, reference being had to the accompanying drawing, in which v Fig. 1 is a side elevation illustrating the improved spout applied to a container with a. tin top,
Fig. 2 is a central vertical section thereof,
Fig. 3 is an inverted plan view of the construction in Fig. 2, showing how the uncturing member curls back the tin an provides spaces upon which the shoulders of the head are wedged when the spout is given a quarter turn,
Fig. 4 is a view similar to Fig. 2 showing the spout in the pouring position, and
Fig. 5 is a detail perspective view of the spout.
The spout 1 comprises a flange 2 which joins the pyramidal puncturing head 3 .through a neck 4. The head 3 has a transverse aperture 5 which communicates with the fluid and air passages 6 and 7 respectively so that when the receptacle R is tilted as in Fig. 4, fluid will flow out of the passage 6 and air will flow in at the passage 7 so as to take the place ofthe displaced fluid.
Each of the aforesaid passages has a cover 8 and 9 respectively, each of which is suitably hinged at 10 and 11 respectively, on adjacent parts of the spout. The purpose of these covers or lids is to close the receptacle when in the upright position (Fig. 1 thereby not only protecting the remaining liquid from dust and dirt, out also preventing the entrance of flies and other insects which may be around. vUpon tiltin the pouring position (Fig. 4) the lids 8 and 9 fa 1 open by gravity so as to provide a free egress for the iquid and also a free ingress for the air.
In operation, the point of the pyramidal puncturing head 3 is pressed through the tin cover 12 of the receptacle R, whereupon the corners 13 will out the metal and the flat sides of the head'will cause it to curl out- Wardly and under, as at 14 in Fig. 3. The entire spout 1 is now given a quarter turn so that the shoulders 15 will move around upon the curled portions 14 which act as bases upon which the shoulders are wed ed in said quarter turn. In order to provi e a cushion and seal the opening through the cover 12, a rubber or other gasket 16 is mounted around the neck 4. The distance between the flange 2 and the. shoulders 15 must be sufficient not only to accommodate the gasket 16 but also the curled over bases 14 the receptacle into It is to be observed, particularly in Fig. 5, that'the shoulders 15 are slightly rounded when viewing the spout in the plane of one of the sides of the head 3. This rounding of the shoulders makes it easier to approach the curled bases 14 when giving the spout the quarter turn which is necessary to seal it in place on the cover 12.
While the construction and arrangement of the improved pouring spout as herein described and claimed, is that of a generally preferred form, obviously modifications and changes may be made without departing from the spirit of the invention or the scope of the claims.
I claim 1. A pouring spout made of a single piece of material comprising a head at one end for puncturing a metallic cover and having an opening extending transversely, a passage in communication with the opening for the -egress of liquid, another pamage in communication with the opening for the ingress of air, and means associated with the respective passages adapted to close them when in a non-pouring position.
2. A pouring spout comprising ahead for puncturing a metallic cover and having an opening, a passa e in communication with the opening for t e egress ofliqu1d, another passage in communication with the opening for the ingress of air, and means pivoted adjacent to the outlet of each passage adapted to close them when the spout is in a non-pouring position and to open them when the spout is in the pouring position.
A pouring spout comprising a puncturing head adapted to curl back the metal from theopening as said head is forced into a metallic cover, shoulders formed on said head which are rounded to more readily ride upon saidcurled-bac-k metal when the spout is given a partial turn, means carried by the spout to seal the opening when thus turned, a liquid passage in the spout in communication with an opening in said head, and an air passage also in communication with said opening for the ingress of air in a pouring operation.
4. A pouring spout comprising a flange, a neck pendent therefrom, a puncturing head attached to the neck, compressiblemeans fitted on, the neck beneath the flange, rounded shoulders formed at the juncture between the head and neck to facilitate wedging the head against curled metallic portions of a cover and compressing the compressible member to form a tight joint, a liquid passage formed in the spout communicating with an opening in the head, an air passage formed in the spout also communicating with said opening in the head, and closure means for the outlet ends of said passages.
5. A ouring spout consisting of one piece having one end formed into a pyramidal puncturing head with a transverse opening, a passage for pouring liquid branching in one direction and having communication with said opening nearest one end, and another passage for the ingress of air branching in the opposite direction and having communication with said opening nearest the other end.
6. A pouring spout comprising a head having sharp edges adaptin it to a piercing function and provided witi an opening of liquid and air, a shoulder situated above the plane of the opening, a washer carried beneath the shoulder permitting making a seal at the place pierced by the head, diverging air and liquid passages having communication with said opening to permit air to flow in as liquid flows out, and covers hinged adjacent to the outlets of said passages in a manner to cause them to move back from said outlets by gravity when the spout is in a pouring position.
7. A pouring spout consisting of one piece having one end formed into a pyramidal puncturing head with a transverse opening, a passage for pouring liquid branching in one direction and having communication with said opening nearest one end, another passage for the ingress ofair branching in the opposite direction and having communication with said opening nearest the other end, a shoulder on the spout situated above the transverse opening, and a washer carried by the spout adapted to engage the shoulder and make a tight joint with the surface which the puncturing head is adapted to impale.
