TABLE Filed March 16, 1931 2 Sheets-Sheet 2 Patented Dec. 13, 1932 UNITED STATES PATENTIOOFFICEF MIRON S. CANADAY, F ROCESTER, MINNESOTA, ASSIGNOR TO REID, MURDOCH & 00., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS TABLE Application filed March 16, 1931. Serial No. 522,829.;

The invention relates generally to tables and more particularly to a table for use in canning for unloading crates of the type disclosed in my copending application Serial No. 456,853, filed May 29, 1930.

Crates of the type disclosed in said application are used as containers for a load of filled cans while the contents are being processed in a retort, the crate suspended from an overhead carrier or hoist which is arranged to lower the crate into a retort and, after the processing in the retort, lift the crate out. The general object of this invention is to provide a new and improved table for use in transferring the cans from a crate to a conveyor after the crate has been removed from a retort and adapted to support or steady the crate while the cans are being removed therefrom.

Another object is to provide such a table having a pair of elevated skid members which act as a brake or support to steady a crate and keep it from swinging on the overhead carrier while it is being unloaded, and which is formed so as to direct the cans removed from the crate onto a conveyor belt passing in front of the table.

Further objects and advantages will become apparent from the following detailed description taken in connection with the accompanying drawings, in which:

Fig. 1 is a plan View of a preferred form of the invention.

Fig. 2 is a front elevation.

Fig. 3 is a section approximately along the line 3-3 of Fig. 2.

Fig. 4 is a perspective view illustrating the preferred form of the invention in operative relation to a conveyor belt.

For purposes of disclosure, I have illustrated in the drawings and shall hereinafter describe in detail a preferred embodiment of the invention, with the understanding that I do not intend to limit the invention to the particular construction and arrangement shown, it being contemplated that various changes may be made by those skilled in the art without departing from the spirit and scope of the appended claims.

In the form illustrated in the drawings,

being generally I the invention is disclosed as comprising a top somewhat rectangular in form and mounted onth'e upper ends of a plurality of legs 11 securedto the corners thereof. Bars 12 are preferably provided intermediate the legs and a plurality of braces 18 are attached between I the legs and the top for. the purpose of providing a strong and rigid structure.

The table is adapted to be positioned ad- 121061113 a conveyor belt 14, as illustrated in Fig. 4, and the top 10 thereof is formed so as to receive cans dumped from a crate 15 (illustrated diagrammatically in Fig. 4) and div,rect them onto the conveyor belt. In its exemplary form the top 10 is of uniformheight along its rear edge 16 and its side edges 17 are inclined downwardly toward the belt 14. The central forward portion 18 of the top is depressed so as to guide the cans towards and discharge them from the central portion of the front of the table. Thus, as illustrated the drawings, thetop comprises a central inclined trlangular portion 19 having its apex adjacent the belt and a pair of side portions 20 and 21 connecting with said central por- 5 tion and sloping upwardly therefrom.

In order to facilitate the unloading of a crate, means is preferably provided which will hold or steady the crate from swinging on its overhead hoist or carrier while it is being unloaded. Such a means is herein disclosed as comprising a pair of parallel transversely extending skid bars or members 22 secured at their opposite ends to the'side edges of the table top 10 and having raised horizontal central portions on which a crate may rest. As illustrated in Fig. 4, thesebars hold the crate in a position so that the cans may be readily discharged therefrom. With the type of Crete disclosed in said prior application, the entire forward portion of the tubular part of the crate swings outwardly so as to permit the cans to be discharged forwardly onto the table from which they roll or may be readily moved onto the conveyor belt 14.

The bars'22 serve effectively as a brake or support for steadying the crates while they are positioned above the table for the purpose of removing the cans therefrom, and the form of thetable top facilitates the transfer 1 of the cans onto the conveyor belt. Some of the cans roll down the inclined portions of the table and it is only necessary to push the others forwardly with but a slight effort to discharge them onto the belt. I

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

1. A table comprising, in combination, a top having an inclined central triangular portion with the apex thereof adjacent the front and lower than the rear edge thereof,.,

and a pair of triangular side portions connected to said central portion along its side edges and sloping upwardly therefrom, a plurality of legs for supporting said top, and a pair of parallel supporting members extending transversely of said top and secured thereto at the side edges, said members having elevated horizontal central portions for engaging and steadying a crate.

2. A table of the character described adapted to be positioned adjacent a travelling conveyor belt for unloading crates carried on overhead hoists or conveyors and comprising a. plurality of legs, a top carried thereon of substantially uniform height along its rear edge and depressed centrally so as to direct cans off the central portion of its forward edge onto said belt, and means extending upwardly from said top adapted to steady a crate while it is being unloaded.

3. A table comprising, in combination, a

: top having an inclined central triangular portion, and a pair of side portions connected to said central portion along its side edges and sloping upwardly therefrom, a plurality of legs for supporting said top, and means ex- I tending upwardly from said top and secured theretoadapted to engage a crate to steady it.

4. A table of the character described adapted to be positioned adjacent a travelling conveyor belt for unloading crates carried on overhead hoists or conveyors comprising a plurality of legs, atop carried thereon having a depressed forward portion arranged to direct cans off the forward edge thereof onto said belt, and a pair of parallel skid bars positioned above the top and secured thereto and adapted to steady a crate while it is "being unloaded.

Signed at Rochester, Minnesota, this 13th day of March, 1931.
