Abstract

A tray for depositing objects in a container utilizes a generally planar member which presents a pouring and sorting surface. The surface has a pair of longitudinally extending converging edges with an outlet opening in the member between the edges for allowing objects to gravitate from the surface. Sidewall structure encloses the surface and extends along the converging edges to cooperate with the member in presenting a pouring spout for directing objects to the opening. A lip projects from beneath the plane of the member and can be placed over an opening in a container to hold one end of the tray, and also facilitate pouring of objects into the container. The lip is located beneath the outlet opening in the member and an extension of the sidewall structure cooperates with the lip to present a funnel extending from the outlet opening. When the member is placed on a surface the lip presents a supporting leg which holds one end of the member in an elevated position to facilitate sorting of objects. The end of the member opposite the lip is of a width sufficient to present a stable base for the tray.

Primary Examiner-Richard A. Schacher Att0mey-Lowe, Kokjer, Kircher & Bowman [57] ABSTRACT A tray for depositing objects in a container utilizes a sorting surface. The surface has a pair of longitudinally extending converging edges with an outlet opening in the member between the edges for allowing objects to gravitate from the surface. Sidewall structure encloses the surface and extends along the converging edges to cooperate with the member in presenting a pouring spout for directing objects to the opening. A lip projects from beneath the plane of the member and can be placed over an opening in a container to hold one end of the tray, and also facilitate pouring of objects into the container. The lip is located beneath the outlet opening in the member and an extension of the sidewall structure cooperates with the lip to present a funnel extending from the outlet opening. When the member is placed on a surface the lip presents a supporting leg which holds one end of the member in an elevated position to facilitate sorting of objects. The end of the member opposite the lip is of a width sufficient to present a stable base for the tray.

7 Claims, 7 Drawing Figures 12. 1 I I V f1 10 SORTING AND POURING TRAY This invention relates to apparatus to facilitate sorting of objects and then pouring of the objects into a container.

In the workshop as well as in certain industrial applications, it is often necessary to sort different objects which have become intermixed and then to pour certain of the objects into a container. Also, it is often necessary to select certain objects from a mixture of objects, and then to pour the remaining objects back into their usual container. While elaborate and expensive sorting apparatus does exist, it is impractical to employ this apparatus in many applications. Although others have provided sorting trays to permit manual sorting of objects, such trays have amounted to no more than mere surfaces upon which to place the objects while they were being separated.

It is therefore an object of the present invention to provide tray apparatus having a sorting surface and which presents a depending lip that fits over the edge of a container to allow objects to be poured into the container with increased speed and without danger of spilling the objects.

An aim of this invention is also to provide tray apparatus which allows objects to be poured into a container with great accuracy because of the lip which depends from the surface of the apparatus, and which greatly facilitates sorting of objects on the surface be cause of an incline which causes lighter objects to gravitate to one end of the apparatus.

As a corollary to the above aim, an object of this invention is also to provide tray apparatus having a surface for sorting objects wherein the surface is supported by a tripod base which offers great stability and reduces the danger of tipping the apparatus and spilling objects from the surface.

Still another object of this invention is to provide tray apparatus for sorting objects and then depositing the objects in a container, which is adaptable to objects of widely varying size and configuration such as nuts and bolts, and B-Bs.

Still another one of the objectives of my invention is to provide tray apparatus for sorting objects and then depositing the objects in a container wherein the sorting surface has elongated converging edges and a sidewall along these edges permits elongated objects to travel along the sidewall and become oriented in parallel relationship thereto, whereby the objects will readily move through an opening located between the converging sidewalls and the opening will not become blocked with objects extending across it.

Still another object of the invention is to provide tray apparatus as above described wherein the sidewall structure is disposed at an angle extending outwardly from the sorting surface whereby a plurality of trays can be stacked one on top of the other.

FIG. 6 is a fragmentary, bottom plan view of the modified form of the invention shown in FIG. 5; and

FIG. 7 is a fragmentary, vertical cross-sectional view of the modified form of the apparatus.

Referring initially to the embodiment of the invention which is shown in FIGS. l-4, the tray apparatus is designated generally by the numeral 10 and includes a polygonally configured member 12 which presents a generally planar pouring and sorting surface 14. Surface 14 is characterized by opposed converging side edges 16 and 18 which converge on one end of member 12.

Enclosing surface 14 is a peripheral side wall structure designated generally by the numeral 20 which is integral with member 12 and extends above the horizontal plane of surface 14 to facilitate retention of objects located on the surface. As best illustrated in FIG. 2, sidewall structure 20 is inclined away from surface 14 thus allowing a number of apparatuses 10 to be stacked one inside of the other. It will also be appreciated from viewing FIG. 2 that sidewall structure 20 is generally rounded as it merges into surface 14, thereby eliminating right angle corners between the surface and the sidewalls which would obstruct movement of objects along the surface adjacent the sidewalls.

Extending upwardly from side edges 16 and 18 are converging

segments

22 and 24 of structure 20. The converging segments of sidewall structure 20 terminate in spaced relationship adjacent the end of member 12 to provide an outlet opening 26 from surface 14.

Segments

22 and 24 cooperate with surface 14 between edges 16 and 18 to define a pouring spout for directing objects to opening 26.

Extending below the plane of member 12 at outlet opening 26 is an integral depending lip 28 which is adapted to be placed over the edge of a container such as 30 in the manner illustrated in. FIG. 4. Integral depending

extensions

32 and 34 of

segments

22 and 24 respectively extend along the'edges of lip 28 to cooperate with the latter in presenting a funnel extending from opening 26. As illustrated in FIG. 3, when apparatus 10 is placed on a horizontal surface 36 pouring and sorting surface 14 will be inclined at an angle relative to the horizontal because of depending lip 28. This facilitates sorting of objects placed on the surface since very light objects will have a tendency to gravitate to the lower end of the surface, while heavier objects will remain at the elevated end. Furthermore, it is to be noted that member 12 has its greatest width at the end opposite lip 28 and this end of greatest width presents a stable base when apparatus 10 is seated on surface 36. There is, therefore, very little danger of apparatus 10 being tipped over and objects being spilled from surface 14 because of the stable tripod effect from lip 28 and the base end of member 12.

After objects in the tray have been sorted on surface 14, if it is desired to deposit certain of the objects in a container such as 30, lip 28 is placed over the container opening as illustrated in FIG. 4, and the entire apparatus 10 is tilted toward the lip to cause objects to gravitate into the container. Since lip 28 holds the tray in perfectly aligned relationship relative to the container opening, only one hand is required to hold apparatus 10 and a person's other hand may be utilized to retain or remove any objects which were sorted from the objects being poured into the container. Subsequently, those objects which have been held back may be poured into a separate container. Manifestly, this completely eliminates the need in many instances to remove one group of sorted objects while the other group is poured into a container. Because of the longitudinally extending converging side edges 16 and 18, and their

adjacent wall segments

22 and 24, large objects such as bolts on surface 14 will first gravitate toward

segments

22 and 24 and will become aligned generally parallel to edges 16 and 18 as the objects gravitate toward opening 26. This assures that the objects will pass through the opening and will not become lodged crosswise in the opening to block the same.

Referring now to the modified form of the invention which is designated generally by the numeral 110 in FIGS. -7, it is seen that apparatus 110 includes a member 12 which presents a generally planar pouring and sorting surface 14 which is enclosed by sidewall structure designated generally by the numeral 20. Apparatus 110 differs from the apparatus described above in that an outlet opening 126 is provided in surface 14 at the end of member 12 toward which

segments

22 and 24 converge. Also, extending below the plane of the member 12 is a depending lip 128 of generally arcuate configuration. Furthermore,

segments

22 and 24 of sidewall structure merge into a generally arcuate segment 38 which provides a shield immediately adjacent the outlet opening. Segment 38 also extends below the plane of member 12 and merges into lip 28 to cooperate with the lip in presenting a funnel extending below the outlet opening.

The modified form of the invention is particularly useful in sorting and pouring small objects with rounded surfaces, such as 8-85, which tend to gravitate from the apparatus 110 with great speed. Because of the shield presented by segment 38 and the enclosed funnel beneath opening 126, such objects are directed into a container without gravitating from the confines of the apparatus as the tray is tilted toward one end.

From the foregoing description it will be apparent that a greatly improved apparatus for the manual sorting and pouring of objects is provided.
