CRATE.

Application filed November 8, 1923. Serial No. 673,420.

The present invention relates to crates and its general object is toeconomize in the use of lumber and at the same time to increase the rigidity and strength of the crate.

A further object of the invention is to provide a crate so constructed for the'specific purpose of packaging automobiles for export shipment in such manner as to reduce the displacement of the package to a minimum.

In the drawings, which illustrate a preferred form of crate embodying the invention Figure 1 is a plan view of the bottom.

Figure 2 is an end view of the bottom.

Figure 3 is a side view of the bottom.

Figure 4: is an inner View of one of the sides.

Figure 9 is a view looking at the lower edge of the end.

Figure 10 is a longitudinal section of the assembled crate.

Figure 11 is a section on the line 1111 in Figure 10.

The bottom, the ends, the sides, and the top of the crate are constructed as separate units which may be secured together to complete the crate. The bottom is formed by longitudinally extending beams or sills 1 to serve as skids and are laterally spaced apart and secured together by a plurality of longitudinally spaced transverse bars 2. The skids are further secured together at each end by transverse bars 3 and l, the outer bars 4 being somewhat shorter than the bars 3 so as to expose surfaces 5 of the skids at the several corners of the crate. A. plurality of longitudinally extending boards 6 are fitted together and secured to the under surfaces of the bars 2, 3 and 4, the under surface of the flooring formed by the boards 6 being above the level of the under surfaces of the skids 1. Longitudinal rails or runners 7 are secured to the respective skids 1,

preferably in abutting relation to the ends of bars 2 and are inset from the outer edges of the skids. As shown in Figures 1, 3 and I 10, I prefer to reinforce the transverse tie bars 2 with cleats 2 nailed or otherwise secured to the rails 7.

Each of the ends of the crate is made u of vertically disposed boards 8 fitted together, the boards being secured together by a transverse member 9 at the top of the end,

a transverse member 10 near the bottom of the end but above its lower edge, and a diagonal brace 11. At its opposite ends the end unit is provided with a vertical post 12 which extends downwardly to the bottom The top of the crate'is formed by longitudinally extending boards 23 fitted together and secured together by transverse members 22.- When the top is in position in the assembled crate it is also supported by cross bars 21 resting on cleats 18 secured against the inner faces and below the top edges of the longitudinal members 16 at the upper edges of the side units. The bars 21 and the bars 22 preferably alternate with each other. I

For the purpose of carrying out the specific object of packaging automobiles for ex port shipment blocks 19 are secured to the skids l toward one end of the crate and the blocks are provided with suitable fastening devices, such as bolts and straps 20, for securing the ends of an automobile axle on the blocks.

In the construction of the crate the bottom, side, end and top units are separately constructed as described, and then assembled to com lete the crate. In the assembled crate the ottom ends of the posts 12, with which each of the end units is provided, rest on the exposed surfaces 5 of the skids 1 at the several corners of the crate, the sides of the lower ends of the posts bearing against the ends of the transverse bars 4 and the ends of longitudinal rails 'Z. The lower transverse member 10 of the end unit rests on the upper face of the transverse bar 4 and aids in ac cepting loads that may be placed upon the top. of the crate to transmit such loads to the bar a'and thus to the skids 1 where they are absorbed. Reinforcing corner braces or cleats 10 may be used if desired. In the assembled crate the lower longitudinal members 15 of the side units rest on the outer portions of the upper sides of the skids l and bear against the outer faces of the Ion. gitudinal rails 7. The ends of the upper 1011-, gitudinal members 16 of the side units. rest on the upper ends 13 of the posts 12 where they enter recesses 13, while the ends 14 of the side units may preferably overlap the ends 12 of the end units falling flush with the outer side thereof as will be understood. The top unit, formed by the; boards 23 and cross bars 22, rests on the upper edges of the side units and the end units and is further supported by the cross bars 21 which rest on the cleats 18 secured to the side units thus placing any load falling upon the top unit upon the vertical side and end units. The several units are securely nailed and spiked together and in addition to the parts described various cleats may be used as'desired.

Itwill be noted that the completed crate is provided on its underside with skids which form the supporting base of the crate and which prevent injury to the floor of the crate if the crate bedragged along a pier or the floor of a building. The skids are securely and rigidly tiedftogether and the end unit-s and side units, are directly supported by the skids themselves. Furthermore the. side units', are also supported by the posts of the end units, thus effecting not only the additional support and strengthening of the sides but also the bracing of the ends and the tying of all of the units together on the skids. It is: advantageous to have the boards of the side units vertically disposed because they can all be secured together and support ed by the longitudinal members 15 which rest on the skids and by the longitudinal members 16 which rest on the posts of the end units and because great stresses will be successfully resisted by the wood in' the direction of its grain length. Similarly iti's advantageous to have the boards of the end units vertically disposed because they can all be secured to and supported by the lower transverse member 10 which rests on the transverse bar 4 supported on the skids. It is also of advanta e to have the boards. of the floor and top of the crate extend longitudinally because they can be secured to the several trans verse bars, thus increasing the strength and rigidity of the crate.

The crate illustrated is specially designed for packaging automobiles for export shipment. For such shipment the wheels and top of the automobile are removed, the wheels usually being hung on the sides of the crate and the top usually being secured over the engine hood. The entire weight of the rear end of the car is supported on the blocks 19 on which the ends of the rear axle rest and to which the axle is secured by the fastening devices 20. The running boards and fenders extend outwardly over the rails 7 and the longitudinal members 15 and only slightly clear the inner faces of] the side boards let while the braces 17 are arranged to clear the slopes of the fenders. The top of the back seat just clears the top of the crate and the ends of the car 'just clear the ends of the crate. The construction of the crate as described makes it possible thus to package the car with very little clearance without sacrificing, butrather increasing, the strength and rigidity of the crate as compared with crates usually used for the pur pose. Of course, the freight on export shipments of this character is-computed by dis placement and the present invention has effected a very large saving in freight payments by exporters of automobiles and at the same time has increased the strength and safety of the package.
