" Knock- Down " Truss System Introduced

A new system of manufacturing roof trusses-allowing them to be disassembled and shipped flat, then re-assembled easily on the job-has been introduced by Component Engineering Co., Lake Oswego, Oregon.

This unique "knock-down" principle, reguiring only a carpenter's hammer for reassembly at the job, is made possible by the use of a patented metal connector plate, applied by pressure at the initial manufacture, then taken apart, leaving the plates still attached to the truss members.

The trusses are assembled on a laree jig, allowing a maximum truss of 40 -x or two smaller trusses to be manufactured simultaneously. An hydraulic press, exerting pressure of 60 tons, moves over the truss and presses the preplaoed CECO truss plates into the members.

As soon as the trusses are removed from the jig, they are knocked down and banded flat for shipping. Company officials claim that an average truck and trailer load of knocked-down trusses will total about 400, whereas an average truck, especially fitted out to carry assembled trusses, will hold only 45 or 50 built-up trusses. The savings in freight costs are obvious.

At the receiving point, the truss€s are reassembled by placing the members in the correct positions and securing the plates with a few holding nails. No job-site jig or special equipment is required.

They emphasize that the trusses cannot (Continued on Page 82)

Jerry Lewis, the big builder

-without driving a nail, he's building a huge pile of Weldwood paneling prospects for United States Plywood dealers on his spectacular new 2-hour "Jerry Lewis Show"

This great show is co-sponsored by United States Plywood. It's a'new idea in TV'programm'ing. Jerry Lewis f,as the scope- to p_lgy many roles-serious, siy, satiiic, wildly hilarious.
