STOCK-BOX. A I

To all whom it may concern;

Be it known that I, WILLIAM PL.

MOND, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Stock-Boxes, of which the following description, in connection with the accompanying drawing, is a specification.

This invention relates to boxes and in particular to boxes used in manufacturing establishments for transporting manufactured articles from one portion of the plant to another, said boxes being practically trays having no tops but permanently open for the deposit of articles therein and so as to be easily emptied. It has been found that boxes used for this purpose deteriorate very rapidly in use owing to the severe treatment which they experience, especially when metal articles are dropped therein, or if the box is emptied by tilting it. It is the objoct of my invention to provide a stock box which will stand an almost unlimited amount of abuse and which at the same time is. not expensive to manufacture.

A feature of my invention is a box comprising pairs of mutually overlapping, opposed side and end members, whereby the collapsing of the side and end members toward each other is prevented, and bolts joining the opposed members of each pair, the top being open and the bottom being easily removable when worn or broken.

The drawing is a View in perspective, with portions broken away, of a box constituting a preferred form of the invention. V The box comprises two side members 10 and two end members 11. The end members are rabbeted at 12 to receive the side pieces 10. It is thus impossible for the side or end members to collapse toward each other. The end and side pieces are channeled at 13 and 14 respectively. Lock rods 15 and 16 are mounted in these channels and extend through the sides and ends of the box.

Angle irons 17 are mounted upon the cor- Specification of Letters Patent. H 23, Application filed September 18, 1915. Serial No; 51,444.

for the corners. The; .rods 1.'O l' etie .bOltSprlfi, 16 are about midway of the height of the box and their ends pass through the angle irons substantially at the mid-length thereof. Therefore when the box is set up it has strong corners although there is but one rod or tie bolt extending through each wing of each angle iron. The tension of the tie rods is applied to the angle irons only at the mid-length of the latter, but that tension is distributed by the upper and lower portions of the angle irons to the upper and lower corner portions of the box to strengthen those portions without employment of other fastening means. The side members 10 are channeled at 19 for the reception of the ends of the bottom boards 20. These bottom boards, when worn or broken, may be easily replaced by new sections after simply removing two of the angle irons and setting one of the side members 10 aside without disassembling the ends 11 from the other side member, and without removing any of the tie rods.

It will be clear that this box is fastened together by four bolts only and that it may be readily knocked down and packed in small compass. It will be clear that the four steel bolts 15, 16 and the angle irons 17 will support the box without injury un der stresses which would wreck a device fastened with ordinary nails and screws. It will be observed also that the bottom of the box exerts a much stronger bracing effect upon the four vertical members than would be true of a bottom which was nailed or screwed to the vertical members since all the distorting stress exerted upon the bottom by the vertical members of the box is a crushing stress without any tendency to split, and the bearing surface communicating stress between the vertical members and the bottom is a maximum. The same is true of the reaction at the corners of the vertical members, where the side and end members mutually overlap. Any attempt to distort the box can result only in a compressive stress upon the vertical members at the corners. There is no tendency whatever to tear the vertical members since all the tensile stresses in the box are taken by the four steel rods. It is contemplated that the vertical and bottom members of the box will be made of wood and it is well known that this material exhibits greater resistance to a bottom for the box removably mounted in compression than to tension. said grooves, a single metal angle plate e111- Having described my invention, what I bracing each corner, anda single adjustable claim as new and desire to secure by United tie bolt extending along the inner face of 5 States Letters Patent is each wall member and passing through an 15 A Wooden box comprising pairs of opangle plate at each corner substantially midposed single Wall members, one pair having Way of its length.
