It is worth while that every approach to the factoryworker should be carefully considered from his stand-point, so that the things which he should understand areunderstood in their proper relation. New Type Returnable Container for Differentials ANEW type of returnable container suitable for usein shipping five differentials has been developedby the Forest Products Laboratory of the U. S. Depart-ment of Agriculture. The new container was perfectedafter two experimental types had failed to withstand thesevere test to which the boxes were subjected. This new container is not only so constructed as toprevent damage or breakage of any kind, but also pro-tects the differentials from dirt, dust and construction of this crate was as follows. Longitudinals—1% x 1% x 36 in., Southern yellowpine. Spacing blocks—2% x 3% x 10% in., Southernyellow pine. The longitudinals are nailed to spacerswith 2-16d cc. box nails at each intersection. Bolts at. the four corners are V2 x 11-in. machine bolts. A cover-ing of 3, 16-in. 3-ply birch is used. Three-ply material is used for covering because it ismuch more durable under rough handling than single-ply material. Practically any species can be used in thiswood covering, but hardwoods, such as black ash, softor silver maple, red gum, sycamore, white elm, hickory,beech, birch, oak, white ash, or rock elm, are preferable. Four pieces of a 4% x 36-in. size, and two pieces,size 9 x 32 in., are required to cover the crate. The cover is nailed on with large headed nails. Six-penny cement coated box nails are best to use withplywood of the hardwood groups, but special largehead nails are advisable if any of the softer woods areused: This crate was developed by the Forest ProductsLaboratory at the request of a large manufacturer ofdifferentials, and can be built as described at a cost ofabout $3. A similar crate, built along slightly modifiedlines, can be made at a cos
