Abstract
Abstract A rigid sawbuck assembly to be supported by four lengths of lumber such as 2×4's which form foldable "X" shaped legs. An elongated axially extending cross bar axle extends between two pairs of juxtaposed metal plates, a pair of which are at each opposite end thereof, journalled on said pipe for rotation. The plates are attached to the lengths of lumber and include lugs on the inner plates of each pair extending from the side edge into the path of rotation of the side edge of the outer plate of each pair to serve as a stop. A cross brace is attached between the lower portions of the innermost legs so that said sawbuck is rigid, foldable, compact and can be stored. Because of the flat plate structure, 2×6's or other sizes of lumber may be used for the legs.

Claim 1
Independent Claim
224 words
Hardware for assembling a rigid saw buck from four lengths of 2"×4" lumber adapted to form two pairs of "X" shaped, foldable legs said hardware comprising: an elongated metal pipe-like cross bar axle of predetermined length having a pair of removable lock means, each at an opposite end thereof and having a pair of collars each fixed thereon at a spaced distance inwardly from one of said lock means; two pairs of elongated flat, planar metal plates, each pair at an opposite end of said metal pipe cross bar axle between one of said lock means and one of said collars, and having registering holes therein journalled on said axle for rotation thereon; the two plates of each said pair being juxtaposed to each other and the inside plates of each said pair having at least one integral lug extending from at least one side edge thereof into the path of rotation of the outer plate of the pair to serve as a stop when said plates are in "X" configuration; said plates each having screw holes for screws for attaching each of said plates near the top of one of said lengths of lumber; and at least one cross brace adapted to extend axially between the lower portions of the two said lengths which are attached to the inside plates of each pair.

Claim 3
Dependent Claim
41 words
Hardware as specified in claim 1 wherein: the opposite ends of said elongated metal, pipe-like cross bar axle are threaded; and said removable lock means comprises a pair of threaded caps, each threaded on one of the ends of said axle.
Claim 4
Dependent Claim
42 words
Hardware as specified in claim 1 wherein: each said inside plate of each pair of flat planar plates includes one of said integral lugs projecting into the rotational path of the outer plate of the pair on each opposite side edge thereof.
Claim 5
Dependent Claim
44 words
Hardware as specified in claim 1 wherein: the outer plates of each pair of plates are free of lugs and the inner plates of each pair, each have a pair of lugs, each on an opposite side edge thereof and at different heights thereon.
Claim 6
Dependent Claim
36 words
Hardware as specified in claim 1 plus: a pair of brackets affixed to the central portion of said cross bar axle; and an upward opening trough extending axially between said brackets and supported on said brackets.
Claim 7
Dependent Claim
41 words
Hardware as specified in claim 1 wherein: said cross brace is a metal pipe with a flanged base at each opposite end thereof adapted to be affixed to the lower portion of the inside face of the inner legs by screws.
Claim 8
Dependent Claim
154 words
A rigid saw buck having a pair of foldable "X" shaped legs at each opposite end thereof, said sawbuck comprising: a metal pipe, cross bar axle having two pairs of flat, planar metal plates journalled, each proximate an opposite end of said axle, for rotation thereon; the two plates of each pair being juxtaposed and each plate of each pair being affixed to a length of 2"×4" lumber near the top thereof to form said "X" shaped legs; one plate of each pair having at least one integral lug projecting from the edge thereof into the path of rotation of the other plate of the pair as a stop when the plates of the pair are in "X" configuration; collar means on said axle for maintaining said plates and legs at a predetermined distance apart; and lock means at the opposite ends of said axle for retaining said plates and legs on said axle.
