Abstract
Abstract This manufacture is a sawhorse, so designed that one will perform tasks that are difficult, if not impossible, with two traditional sawhorses. Parallel but separated backs support wide materials for sawing, cutting, or drilling. Narrow materials are supported by the legs and contained between the backs. Kerfs in the backs are aligned to permit forty-five and ninety degree cuts when the backs are used as a miter box. The legs are constructed to hold tools used in the construction process. The sawhorse assembles and disassembles without tools, and it stores and transports flat.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
148 words
A saw horse comprising two essentially vertical, trapezoidally shaped plate-type legs, connected to two parallel horizontal backs, spaced substantially apart, said connection being accomplished by opposing matched notches on said legs and backs, said notches being of sufficient depth to provide stability in the longitudinal direction of the backs and to provide a fixed dimension between the backs for the insertion of lumber and to provide a vertical space between the top surface of the back and the top edge of the legs, said backs having kerfs cut at commonly used angles in construction at the same depth as that existing between the tops of the backs and legs, and having holes cut perpendicularly to the longitudinal direction of the backs supporting removably positioned nails at a depth from the top surface of the backs generally sufficient to enclose and support lumber for mitering in the said kerfs.
