Claim 8

Dependent Claim 87 words

The apparatus of claim 1, in which said positioning means comprises a pair of blocks adapted to slide in a substantially horizontal direction, a pair of positioning pins, each pin disposed on a respective slide block, opposite one another, and a member adapted to move in a substantially vertical direction and coupled to each of said slide blocks, so that when said member is raised, said blocks and pins extend towards one another in the substantially horizontal direction, to contact and position the part upon the pallet.

Claim 9

Dependent Claim 80 words

The apparatus of claim 4, in which the pallet comprises a pair of bars movably disposed on the base and adapted to retain the part disposed thereon, a pair of steps on said base, each step disposed on a respective side of said hole, and means for urging the bars close to one another to retain the part on the pallet, said urging means comprising a pair of leaf springs, each leaf spring seated between a respective step and bar.

Claim 10

Dependent Claim 130 words

The apparatus of claim 1, in which said receiving and mounting means comprise a rotatable shaft rotatably mounted in a frame of said apparatus and adapted to rotate at discrete intervals, an indexing disc disposed upon said rotatable shaft, a plurality of said mounting heads disposed at discrete radial intervals about said indexing disc, each mounting head comprising a suction pin for drawing the part off a respective pallet, and a through-slide member engaged with a respective suction pin, said receiving and mounting means additionally comprising a support plate disposed on a rear side of said indexing disc and affixed to the frame of said apparatus, and at least one actuating slider slidably disposed upon said support plate and adapted to actuate the through-slide member to extend said suction pin.

Claim 11

Dependent Claim 24 words

The apparatus of claim 8, in which said actuating slider is adapted to engage a rear portion of said through-slide member at predetermined intervals.

Claim 12
