Claim 4

A lift saddle for holding irregularly-shaped workpieces such as vehicle transmissions, comprising a base plate having substantially parallel front and rear edges and a pair of substantially parallel side edges extending substantially at right angles to said front and rear edges, a front arm and a rear arm forming a first pair of arms and a second pair of side arms slidably mounted on said plate for independent movement transversely respectively to said edges, means fixing the adjusted position of each of said four arms with respect to said plate, and upwardly extending means fixed to each arm for engaging a workpiece to be lifed, the inner ends of one pair of arms overlapping those of the other pair when all arms are in their inner positions.

Claim 5

A lift saddle for holding irregularly-shaped workpieces such as vehicle transmissions, comprising a base plate having substantially parallel front and rear edges and a pair of substantially parallel side edges extending substantially at right angles to said front and rear edges, a front arm and a rear arm forming a first pair of arms and a second pair of side arms slidably mounted on said plate for independent movement transversely respectively to said edges, means fixing the adjusted position of each of said four arms with respect to said plate, and upwardly extending means fixed to each arm for engaging a workpiece to be lifted, and tubular spacers carried by the underside of said plate and engageable with the pad of a lifting jack, said spacers being in non-obstructing relation with said arms.

Claim 6

A lift saddle for holding irregularly-shaped workpieces such as vehicle transmissions, comprising a base plate having substantially parallel front and rear edges and a pair of substantially parallel side edges extending substantially at right angles to said front and rear edges, a front arm and a rear arm forming a first pair of arms and a second pair of side arms slidably mounted on said plate for independent movement transversely respectively to said edges, means fixing the adjusted position of each of said four arms with respect to said plate, and upwardly extending means fixed to each arm for engaging a workpiece to be lifted, and tubular spacers carried by the underside of said plate and engageable with the pad of a lifting jack, said spacers being in non-obstructing relation with said arms.

Claim 7

A lift saddle for holding irregularly-shaped workpieces such as vehicle transmissions, comprising a base plate having substantially parallel front and rear edges and a pair of substantially parallel side edges extending substantially at right angles to said front and rear edges, a front arm and a rear arm forming a first pair of arms and a second pair of side arms slidably mounted on said plate for independent movement transversely respectively to said edges, means fixing the adjusted position of each of said four arms with respect to said plate, and upwardly extending means fixed to each arm for engaging a workpiece to be lifted, one pair of arms being engageable directly with said plate, the other pair being spaced from the plate by approximately the thickness of the first pair and having inner ends which overlap the inner ends of the first pair when all the arms are in their inner positions.

Claim 8

A lift saddle for holding irregularly-shaped workpieces such as vehicle transmissions, comprising a base plate having substantially parallel front and rear edges and a pair of substantially parallel side edges extending substantially at right angles to said front and rear edges, a front arm and a rear arm forming a first pair of arms and a second pair of side arms slidably mounted on said plate for independent movement transversely respectively to said edges, means fixing the adjusted position of each of said four arms with respect to said plate, and upwardly extending means fixed to each arm for engaging a workpiece to be lifted, one pair of arms being engageable directly with said plate, the other pair being spaced from the plate by approximately the thickness of the first pair and having inner ends which overlap the inner ends of the first pair when all the arms are in their inner positions.

Claim 9

The combination according to claim 4, further provided with spacer means for said last pair of arms comprising a pair of U-shaped members secured to the underside of said plate.

Claim 10

A lift saddle for holding irregularly-shaped workpieces such as vehicle transmissions, comprising a base plate having substantially parallel front and rear edges and a pair of substantially parallel side edges extending substantially at right angles to said front and rear edges, a front arm and a rear arm and a pair of side arms slidably mounted on said plate for independent movement transversely respectively to said edges, means fixing the adjusted position of each of said four arms with respect to said plate, and upwardly extending blades fixed to each arm for engaging a workpiece to be lifted, two of said blades being secured to the outer ends of said arms, major portions of said last-mentioned blades extending above their arms with other portions extending below the arms, the other two blades being secured slightly inwardly from the ends of thier arms and extending upwardly, and a safety chain extending between the outer ends of said two last-mentioned arms.
