An adjustable leg support assembly that includes a cross brace slidably mounted on a center support and projecting laterally therefrom to opposed ends spaced from the center support. An upper clevis is slidably mounted on the center support above the cross brace. A pair of legs each have one end affixed to the upper clevis, a lower end and a center portion affixed to associated ends of the cross brace. An attachment arrangement is selectively mountable at the upper end of the center support for attachment of structure to be supported. The upper clevis may be adjustably affixed to the center support such that the attachment structure on the center support is adjustably positionable with respect to the lower ends of the legs.

An automatic indexer a portable sheet bending brake having a first longitudinally extending member forming a clamp surface, a second longitudinally extending member movable with respect to the first member for clamping sheet material against the clamp surface, and a third member pivotally coupled to the second member for bending sheet material clamped between the first and second members over a bending anvil on the forward edge of the second member. The indexer includes a pair of slides having means for mounting the slides parallel to each other and spaced from each other lengthwise of the clamp surface on the bending brake. A pair of carriages are each slidably disposed on one of the slides, and a bar extends longitudinally between the carriages for engagement with an edge of sheet material inserted between the first and second members of the sheet bending brake. The carriages are resiliently biased toward the clamp surface of the sheet bending brake, and means are coupled to the carriages for relating distance between the anvil to the edge of sheet material in engagement with the bar. This distance is either a direct measure to the edge of the anvil for forming indexed bends, or an offset distance with respect to the anvil for indexing the sheet material for a cut employing a manual slitter that cuts the material at a predetermined offset distance from the anvil edge. Thus, the indexer automatically squares the cut or bend to the edge in engagement with the indexer, and automatically positions the bend or cut with respect to the anvil edge as controlled by the indexer.

A portable saw table comprising a saw track pivotally supported on a saw table. An improved lightweight plastic protractor and indexer plate are rotatably mounted with respect to each other by an improved pivot mount. The pivot mount comprises a plurality of lobes received in a complementary recess in the indexer plate in a spline-like engagement providing strength and rigidity to prevent flexing to ensure accurate pivotal movement. The improved protractor is guided by a gib mounted on the indexer plate for smooth pivotal movement. The plastic protractor includes indicia to indicate the degree of angular movement and the plastic indexer plate includes a window for viewing the indicia. In one form, the protractor has an angled portion with indicia and the indexer plate has an angled magnifying sight lens for easy viewing of the adjustment angle. A hollow material stop is provided to accommodate workpieces of varying thickness. U-brackets hold the saw shoe plate to the saw slide and a spring loaded saw stop prevents the saw slide from sliding past the ends of the saw tracks. Additionally, an adjustable leg assembly is provided for adjusting the height of the saw table and is removable therefrom.

Portable saw table

A portable saw table comprising a saw track pivotally supported on a saw table. A protractor is mounted on the saw track and an indicator-indexer plate is mounted on the saw table. A hand operated locking mechanism is provided. The saw table includes laterally extensible side members and longitudinally extending end members.
