Herewith is a sketch of a tressle which may be readily taken down and stored away in some small corner of the shop, writes W. E. Morey in the "American Machinist."

A Folding Trestle 315

The top bar or rail A is provided with grooves near each end, formed by nailing strips of wood on each side as shown at a a a. The legs, one of which is shown at B, has a space b at the top which is a pretty close fit over the top bar, and the strips on each side of the top bar are a close fit on the upper end of the legs. This trestle is not so useful in the machine shop, possibly, as in some other lines, but its collapsible feature is perhaps worthy of your attention. It is certain that the old form of trestle is a very unhandy contrivance to store awav when not in use.
