Pour spout construction

Claim 2

A pouring spout including a multi-sided hollow body, a hollow outwardly tapering prong carried by and projecting outwardly from one side of said body, said one side of said body having an opening formed therein communicating the interiors of said prong and body for rapid flow of granular material from within the interior of said prong into the interior of said body, said body defining a discharge opening remote from said prong, closure means shiftably supported from said body and rapidly movable into and out of positions closing and opening the discharge opening, said prong including side walls extending outwardly from said body and converging toward a pointed outer end of said prong, spring means operably connected between said body and closure means yieldingly biasing the latter toward its closed position, and operator means shiftably supported from said body and operatively connected with said closure means for movement of said closure means between its open and closed positions upon shifting of said operator means relative to said body, said prong being in the form of a multisided pyramid, two adjacent sides of said prong being defined by the sets of corresponding legs of a plurality of side-by-side V-shaped teeth spaced along said prong and progressively increasing in size outwardly from said body.

Claim 3

The combination of claim 1 including elongated tine means extending along the upper apex portions of said inverted V-shaped teeth, the end of said tine means adjacent said body being pivotally supported therefrom for oscillation about a horizontal transverse axis and including a tab portion projecting into said body through an opening provided therefor, the portion of said tab projecting into said body being engageable by said operator means for oscillating said tine means in response to back-and-forth shifting of said operator means.

Claim 4

A pouring spout including an upstanding elongated hollow body, a hollow outwardly tapering prong carried by and projecting outwardly from one side of said body, said one side of said body having an opening formed therein communicating the interiors of said prong and body for rapid flow of granular material from within the interior of said prong into the interior of said body, the lower end of said body defining a downwardly opening discharge opening, closure means shiftably supported from said body and rapidly movable into and out of positions closing and opening the discharge opening, said prong including side walls extending outwardly from said body and converging toward a pointed outer end of said prong, at least one of said prong side walls having at least one opening formed therethrough, spring means operably connected between said body and closure means yieldingly biasing the latter toward its closed position, and operator means shiftably supported from said body for back and forth oscillating movement relative thereto between active and inactive positions and readily engageable from the exterior of said body, connecting means operatively connected between said closure means and said operator means for movement of said closure means between its open and closed positions upon shifting of said operator means between its active and inactive positions, respectively, said connecting means including an elongated longitudinally reciprocal rod extending lengthwise in said body, connected at its lower end to said closure means, and connected at its upper end to said operator means, wherein said prong is generally in the form of a three-sided pyramid, at least two sides thereof having at least one opening formed therethrough, wherein said two sides of said pyramidal prong are defined by the sets of corresponding legs of a plurality of inverted V-shaped teeth spaced along said prong and progressively increasing in size outwardly from said body, the third side of said prong closing the space between the legs of the outermost inverted V-shaped tooth.

Claim 5

A pouring spout including an upstanding elongated hollow body, a hollow outwardly tapering prong carried by and projecting outwardly from one side of said body, said one side of said body having an opening formed therein communicating the interiors of said prong and body for rapid flow of granular material from within the interior of said prong into the interior of said body, the lower end of said body defining a downwardly opening discharge opening, closure means shiftably supported from said body and rapidly movable into and out of positions closing and opening the discharge opening, said prong including side walls extending outwardly from said body and converging toward a pointed outer end of said prong, at least one of said prong side walls having at least one opening formed therethrough, spring means operably connected between said body and closure means yieldingly biasing the latter toward its closed position, and operator means shiftably supported from said body for back and forth oscillating movement relative thereto between active and inactive positions and readily engageable from the exterior of said body, connecting means operatively connected between said closure means and said operator means for movement of said closure means between its open and closed positions upon shifting of said operator means between its active and inactive positions, respectively, said connecting means including an elongated longitudinally reciprocal rod extending lengthwise in said body, connected at its lower end to said closure means, and connected at its upper end to said operator means, wherein said prong is generally in the form of a three-sided pyramid, at least two sides thereof having at least one opening formed therethrough, wherein said two sides of said pyramidal prong are defined by the sets of corresponding legs of a plurality of inverted V-shaped teeth spaced along said prong and progressively increasing in size outwardly from said body, the third side of said prong closing the space between the legs of the outermost inverted V-shaped tooth.

Claim 6

The combination of claim 3 wherein said closure means comprises a door extending across the lower end of said body and hingedly supported at one marginal portion from a corresponding marginal portion of said body for swinging about a horizontal axis.

Claim 7

The combination of claim 4 wherein the upper end of said body defines an upwardly opening bore opening inwardly into the interior of said body, said operator means comprising a push button reciprocal in said bore and projecting outwardly of the upper end thereof, the upper end of said rod being anchored to said button.

Claim 8

The combination of claim 5 wherein said button and the upper end portion of said body include coacting button and body portions defining limits of shifting of said button relative to said body.

Claim 9

The combination of claim 6 wherein said spring means comprises a compression spring disposed about said rod between said button and one of said body portions.

Claim 10

The combination of claim 2 wherein said two sides each have a plurality of parallel slot-type openings formed therethrough.

Claim 11

The combination of claim 2 wherein the juncture between adjacent pairs of sides of said pyramid define sharpened outer edges.

Claim 12

The combination of claim 3 including elongated tine means extending along the upper apex portions of said inverted V-shaped teeth, the end of said tine means adjacent said body being pivotally supported therefrom for oscillation about a horizontal transverse axis and including a tab portion projecting into said body through an opening provided therefor, the portion of said tab projecting into said body being engageable by said operator means for oscillating said tine means in response to back-and-forth shifting of said operator means.
