2 Claims. (Cl. 248120) This invention relates generally to pallets of the type adapted for use in warehouses, and more particularly to certain improvements therein for rendering the same especially applicable for the storage of large and heavy articles, such as, mattresses, bed-springs and the like, stacked on edge 5 flush with the upper surface of the pallet to render upon the pallet so as to facilitate individual selecthe same capable for use as a conventional pallet. tion of any one of such articles from a group Other objects of this invention will appear more thereof. fully hereinafter.

2 the purposes aforesaid which is characterized by the provision of side extension arms which are readily disposable in vertical position to support large articles stacked on edge upon the pallet and as readily disposable in horizontal position In accordance with the present invention, the pallet is provided with one or more pivoted arms 14 upon each side thereof, the pallet illustrated being shown as provided with two such arms upon either side. Each of said arms I4 is pivotally mounted upon a side cleat ID with its pivoted end disposed between a pair of adjacent cross boards II by means of a suitable hinge [5, such as is shown in Figure 5. Each of these hinges I5 is provided with a pair of angularly related arms lB-ll hingedly secured together by a pin l8, the longer arm l6 being bent, as at l9, so that the outer portion 20 thereof may be swung into a position parallel to but ofi'set from the arm H or into a position extending at right angles thereto. The arm "of each hinge is adapted for securement to the inner face of each sidemost cleat III, while the outer portion 20 of the hinge arm i8 is adapted for securement to one of the side arms I4, all as shown most clearly in Figures 3 and 4.

Each of the sidemost cleats ill, in the regions of securement of the hinges I5 thereto, is notched, as at 2|, to provide an inclined surface 22 against which the inner portion 23 of the hinge arm l6 may rest when the hinge is swung into the position shown in Figure 4, it being noted that when the hinge is swung into this position the side arm extension I4 extends vertically and is restrained from outward movement beyond the longitudinal side edge of the pallet by the fact that the inclined surface 22 of the hingereceiving notch 2| serves as a limiting stop for the hinge arm IS.

The side arms ii are each of a thickness equal to that of the cross boards H so that when the former are swung into their lowered positions (as shown in Figure 2 and at the left of Figure 3) they lie substantially flush with the upper surface of the pallet. The length of each side extension arm I4 is preferably such that when in its lowered position its free end rests upon the central longitudinally extending cleat III.

The side extension arms I4 are preferably made of wood, but they may be formed of any other suitable material, such as metal, in which event they may be of a thickness and width substantially less than those of the cross boards ll. While in the construction illustrated, the side extension arms are arranged in opposed pairs so that the free ends of each pair commonly rest upon the central cleat l0, it will be understood that these arms may be arranged in staggered relation so as to provide for greater length of each arm and so increase their vertical extent for higher side support of articles stacked on the pallet.

It will be understood, of course, that the present invention is susceptible of various changes and modifications which may be made from time to time without departing from the real spirit or general principles thereof, and it is accordingly intended to claim the same broadly as well as specifically as indicated by the appended claims.

What is claimed as new and useful is:

'1. A pallet comprising spaced parallel cleats, spaced parallel cross boards connecting said cleats and collapsible supporting members hingedly mounted on opposite sides of the pallet upon the end cleats thereof in the space between cross boards and adapted alternatively to lie in the horizontal plane of said cross boards in the spaces therebetween or to extend upwardly therefrom.

2. A pallet comprising spaced parallel cleats, spaced parallel cross boards connecting said cleats and collapsible supporting members hingedly mounted on opposite sides of the pallet upon the end cleats thereof in the space between the same adjacent cross boards and adapted alternatively to lie in the horizontal plane of said cross boards in the spaces therebetween with the ends of said members resting" upon the upper face of the center cleat in said space or to extend upwardly from said plane.
