Abstract
Abstract Apparatus for transferring labels from a magazine to containers and including a transfer drum rotor having a series of peripherally located shafts with label transfer pallets swingable therewith and control mechanism for turning the shafts, the shafts and pallets being pre-assembled in adjustably fixed relation and the shafts having parts which interlockingly key with a complementary keyed part on the drum, whereby one shaft and pallet assembly is removable as a unit from the drum for replacement by a substitute shaft and pallet assembly, the shaft of which has a similarly keyed part which interfits with the complementary keyed part on the drum. Keying of the shaft to the drum is desirably accomplished by a bushing which is adjustably clamped to the control mechanism and which has a socket which constitutes the keyed part of the drum.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
In apparatus for transferring labels from a magazine to containers and including a transfer drum rotor having a series of peripherally located shafts, pallets swingable with said shafts, and control mechanism for turning said shafts to impart swinging motion to the pallets, the improvement comprising pre-assembled pallets and shafts in adjustably fixed relation, said shafts having keyed parts, said drum having complementary keyed parts for coaction with the keyed parts of said shafts, whereby one shaft and pallet assembly is removable as a unit from the drum and is replaced by a substitute shaft and pallet assembly, the shaft of which has a keyed part which interfits with a complementary keyed part on the drum, said keyed parts comprising interfitting sockets and tongues having complementary noncircular configurations.

Claim 3
Dependent Claim
12 words
The invention of claim 1 in which said configurations comprise complementary polygons.
Claim 4
Dependent Claim
