PICKLING CRATE Filed Aug. 21, 1955 I Char/es I/Vabson INVENTOR.

Patented Jan. 5, 1937 UNITED STATES PATENT OFFICE PICKLING CRATE Charles G. Watson, Austintown, Ohio Application August 21, 1935, Serial No. 37,152 2 Claims. (01. 266-7) This invention relates to crates.

The principal object of this invention is to provide a pickling crate such as is used in the conveying of metal sheets and in immersing the same in a pickling vat. While crates for carrying sheet metal are known to the art it is desirable to construct a crate which is relatively light in weight, yet extraordinarily strong for conveying and lifting heavy loads of sheet metal.

A still further object is to provide cross beams formed of two oppositely disposed plates. Each plate is sheared and stamped so as to form a semi-V-shaped member between the shearings. The two plates are then placed so that a beam is constructed by placing the bottoms of the semi-V-shaped members upon each other and welding the same together.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:--

Figure 1 is a top plan view of the crate.

Figure 2 is an enlarged detail view in perspective showing more clearly the assembled structure of the crate.

Figure 3 is a detail perspective view showing a section of the beam in order to more clearly illustrate the manner in which the oppositely disposed plates with semi-V-shaped members are assembled before welding.

Figure 4 is a cross section taken on line 4-4 of Figure 2.

Figure 5 is a cross section taken on line 5-5 of Figure 1.

By referring to the drawing it will be seen that there is provided a crate having a pair of oppositely disposed side frame members I. Between these frame members I, at desirable intervals, there are positioned a plurality of cross beams 2 spaced apart and preferably welded to the inner surfaces of the side frame members I. 50 For convenience in lifting and conveying the crate there are provided lugs 3 spaced apart on the outer sides of the frame members.

By referring to Figure 2 it will be seen that there is shown an I bar 4 placed upon one of 55 the lugs 3. These I bars are used for the purpose of attaching lifting means such as a crane.

By referring to Figures 2 and 3 it will be seen that the beams 2 are constructed of a pair of oppositely disposed plates 5, each plate having a plurality of stamped sheared portions forming 5 semi-V-shaped portions 6. It will also be seen that the beams 2 are constructed by placing the apexes of the semi-V-shaped portions in contact with each other and then securing as shown in Figure 4 by a weld 1. 10

By referring to Figure 2 it will be seen that this structure, when completed as above described, provides a beam of maximum strength, yet of minimum weight. In the construction of the beam 2 the X-shaped truss formation formed by 15 the semi-V-shaped portions 6 is formed from material sheared in the plates 5 and is an integral part of the same.

By referring to Figure 2 it will also be seen that the upper plate 5 is provided with a spacer memher 8, provided with a plurality of notches so that when sheets are loaded upon the crate they are held apart when supported by means of spikes 9 which pass through openings l0 and II in the upper and lower plates 5. 25

It will also be seen that in order to hold the spacer member 8 in a proper position upon the upper plate 5 there is provided a pair of oppositely disposed lugs [2.

It is understood that the pickling crate above described may be made of any suitable material, but is preferably made of Monel metal.

I claim:

1. In a pickling crate, a pair of oppositely disposed side frame members, a plurality of cross beams spaced apart and welded to inner sides of said frame members, a pair of plates forming each of said beams, and sheared and stamped semi-V-shaped portions on said plates, apexes of said semi-V-shaped portions welded together making the plates integral with each other in forming said beam, lugs spaced apart on outer sides of said side frame members for carrying and lifting said crate, a spacer member on upper plate provided with notches for holding sheets of metal in spaced relation to each other, a plurality of spikes for supporting said sheets of metal, substantially as described.

2. In a pickling crate, a pair of oppositely disposed side frame members, a plurality of cross 5 beams spaced apart and welded to inner sides of said frame members, a pair of plates forming each of said beams, and sheared and stamped semi-V-shaped portions on said plates, apexes of said semi-V-shaped portions welded together making the plates integral with each other in an X-shaped truss formation, lugs spaced apart on outer sides of said side frame members for carrying and lifting said crate, a spacer member on upper plate provided with notches for holding sheets of metal in spaced relation to each other,

a plurality of spikes for supporting said sheets of metal, a pair of oppositely disposed lugs for holding said spacer member in proper position, substantially as described.
