Abstract
Abstract Gang saw for edger having boss saw which is a cluster of two or more circular saws at fixed spacing. Boss saw is mounted on rotatable shaft with additional saw, saws being independently slidable along shaft. Movable diverter can be aligned with selected saw of cluster so that cluster itself can be used alone as gang saw to produce lumber of fixed width. Fast conversion to gang saw to produce lumber of different width from that produced by cluster.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
255 words
A gang saw having a boss saw and at least one additional circular saw (402), the saws being mounted on a rotating shaft and being adapted for motion of translation along the shaft, wherein a. the boss saw (401) is a cluster of at least two circular saws (401.1, 401.3) spacing between the saws of the boss cluster being fixed; the two saws being an outside saw (401.3) adjacent the additional saw, and an inside saw (401.1), b. a fixed diverter c. means (411, 412.1) to move the additional saw axially of the shaft, so as to alter its spacing from the boss cluster, d. means (411, 411.1) to move the boss cluster axially of the shaft, the additional saw moving equally therewith, so that any selected saw of the boss cluster can be aligned with the fixed diverter, e. a movable diverter (408), f. means (415, 416) to move the movable diverter to align it with the additional saw at a particular spacing from the fixed diverter, constructed and arranged so that a cant having a width somewhat greater than the spacing between the fixed and movable diverters is trimmed to a width according to that spacing, and is also cut longitudinally to produce at least two pieces of dimensioned lumber when the inner saw of the cluster is aligned with the fixed diverter; and so that either the trimmed cant or the dimensioned lumber can be produced at will according to which saw of the boss cluster is aligned with the fixed diverter.
Claim 2
Dependent Claim
255 words
A gang saw having a boss saw and at least one additional circular saw (402), the saws being mounted on a rotating shaft and being adapted for motion of translation along the shaft, wherein a. the boss saw (401) is a cluster of at least two circular saws (401.1, 401.3) spacing between the saws of the boss cluster being fixed; the two saws being an outside saw (401.3) adjacent the additional saw, and an inside saw (401.1), b. a fixed diverter c. means (411, 412.1) to move the additional saw axially of the shaft, so as to alter its spacing from the boss cluster, d. means (411, 411.1) to move the boss cluster axially of the shaft, the additional saw moving equally therewith, so that any selected saw of the boss cluster can be aligned with the fixed diverter, e. a movable diverter (408), f. means (415, 416) to move the movable diverter to align it with the additional saw at a particular spacing from the fixed diverter, constructed and arranged so that a cant having a width somewhat greater than the spacing between the fixed and movable diverters is trimmed to a width according to that spacing, and is also cut longitudinally to produce at least two pieces of dimensioned lumber when the inner saw of the cluster is aligned with the fixed diverter; and so that either the trimmed cant or the dimensioned lumber can be produced at will according to which saw of the boss cluster is aligned with the fixed diverter.
Claim 3
Dependent Claim
112 words
A gang saw as defined in claim 1, wherein the boss cluster has more than two saws (eg. 401, 402, 403), and wherein there are at least two additional saws (eg. 402, 403), and g. means (eg. 411, 411.1, 411.2) to alter the spacing between the additional saws h. means as aforesaid to move the boss cluster, the additional saws moving therewith, constructed and arranged so that dimensioned pieces can selectively be produced from the cant in a maximum number equal to the total number of saws minus one, the number of pieces and their dimensions being determined by depth of the cant, spacing between the saws, and position of the diverters.
Claim 4
Dependent Claim
30 words
A gang saw as defined in claim 2, and means (416) to move the movable diverter independently to a position of alignment with a selected saw of the boss cluster.
Claim 5
Dependent Claim
44 words
A gang saw as defined in claim 3, wherein the means to move the boss cluster so that a selected saw of the cluster is aligned, as aforesaid, with the fixed diverter includes; a boss cylinder (411-B), and an independently operable additional cylinder (411-A).
