PALLET;

Appucaaon aieanay 1s', 1927; Serna No, 192,230.

My invention relates to palletslused in. con nection with the manufacture of cement blocks, concrete tiles, clay tiles and hollow tiles.

As is well known, during the course ofthe manufacture of such blocks, the latter, after being molded, are placed upon separate pallets and the latter then placed upon a con veyor which carries them through a` drying oven. After emerging from the latter, the pallets with the blocks are removed and stacked up and allowed to stand and permit a further drying out and curingof the blocks.

As a large number of palletsfmust be used, it is essential that they be made at small expense and at the samev time be of' sufficiently stable construction to successfully withstand continuous usage and also withstand the warping action ofthe heat.

Pallets have heretofore been made of sheet metal, but necessarily of material so thin that it easily warps and bends so that the floor of the pallet becomes uneven and unsuitable for supporting the soft molded block before it is dried or hardened. Such metal also rusts as a result of its contact with the wet concrete.

They have also been made of wood, but in a manner such that the use of long nails was resorted to for securing the end members to the floor, which often resulted in splitting such members, with consequent Waste and increased cost of manufacture. When such nails were employed, they also frequently failed to prevent warping of the floor.

i The object of the invention is to produce a wooden pallet, easily assembled or disassembled, the method of vand character of the construction of which will be simple, will obviate the necessity of using nails, which will resist warping to the greatest possible degree, and which is reversible.

My said invention therefore consists of a wooden pallet construction hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various forms in which the principle of my invention may be employed.

In said annexed drawings:

Figure l represents a planof a pallet em F bodying my invention.

\ fasteningy the parts together.

ln the embodiment of my invention as` Fig. 2 represents a front elevation.

Fig.l 3 represents an end view.

Fig. t represents a perspective view of oneof the floor members.

Fig. 5 represents a perspective view of one of the end members.

Fig. G represents one o the boltsused for illustrated, the pallet includes a wooden floor l, four wooden end members 2 all of the same size and shape, and two fastening parallel with each other andi havingv 'their inner longitudinal edges separated from eachother by a rectangular space 4r.

The opposite faces of `each wooden endk portion of the floor members are rabbeted to form oppositely disposed transverse surfaces 5, 5, converging inwardly of the floor members as shown in Figs. 2 and il, forming transverse shoulders 5-5.

The inner ends of the end members 2 are beveled as at 2, Fig. 5, and engage the rabbet surfaces and the shoulders 5', Fig. 2, the inclination being such as to cause the end members to be perpendicular to the floor.

Each end member 2 is provided with a central vertical hole 6, and through each pair of alined holes and between the floor members l-l, passes a bolt 3 provided with a .nut 3. These bolts and nuts therefore hold and draw the end member lirinly to the seats formed by the rabbet surfaces. T he inclined form of the latter, and the shoulders 55 prevent the end members from becoming displaced by turning about the bolts, so that a very secure and firm joint is formed between these members and the floor.

The outer end of each end member is preferably provided with a central recess 7 which permits the ends of the bolts to be removed from the extreme end plane of said members so that they will not interfere with the placing of the pallet upon a flat surface. These recesses also allow the operator to insert his hands beneath the pallet for lifting same olf the conveyor or other support, as will be understood.

The space l permits of access of air beneath the floor, whereby the drying-out process is facilitated, as will be understood. By separating the two floor members, the

(lli

necessity of providing holes in them for the bolts, is obviated.

It will be seen from the above const-ruction, that the pallet parts may be readily assembled Wit-hout injury to any such parts, or disassembled for replacement of any one or more of the latter. Also that each pair of end members and its bolt clamps the end portions of the fioor members tightly and prevents them from warping.

Furthermore it will be seen that since the end members are all alike, the structure in both faces of the door is symmetrical and the device hence reversible.

That I claim is:

l. A pallet consisting of a floor composed of two members separated from each other at their inner edges; members at each end of said floor extending transversely of and from opposite faces thereof; a single bolt extending through each pair of oppositely disposed members and between the said two floor members; and a nut for securing said bolt in place.

2. A pallet 'consisting of a floor; members at each end of said floor extending transversely of and from opposite faces thereof;

and means for securing said end members to the floor; the end portions of the latter being provided With inwardly converging abbot surfaces, the inner ends of the end members being beveled to fit such surfaces.

3. A pallet consisting of a floor; members at each end of said floor extending trans versely of and from opposite faces thereof; the end portions of said iioor being provided with inwardly converging rabbet surfaces, the inner ends of said members being formed to it such surfaces; a Isingle bolt passing through each pair of oppositely disposed end niembers for securing same to said iloor; and a nut for securing said bolt in place.

Li. A pallet consisting of a floor composed of two members separated from each other by their inner edges; members at each end of said floor extending transversely and from opposite faces thereof; the end portions of said floor members being provided with inwardly converging rabbet surfaces, the inner ends ofsaid end nien'abers being formed to fit snch surfaces, a single bolt passing through each. pair ot oppositely disposed end members and between said floor members for securing same to said floor members; and a nut for securing said bolt in place.
