Abstract
Abstract A conveyor for assembling apertured workpieces adapted to be received one within another, comprising a conveyor chain with external and internal links, pivotally connected with one another, each connection including a bushing sleeve having an axial duct therethrough, a cylindrical assembling mandrel extending through the axial duct of each bushing sleeve, the mandrels being displaceable in relation to the links of the conveyor chain, each mandrel having a tail portion at the upper end thereof, the tail portions of the mandrels being adapted to extend through the apertures in the workpieces being assembled, each mandrel having at least two radially projecting splines extending longitudinally thereof, the internal shape of the axial duct within each bushing sleeve being complementary to the shape of that portion of the mandrel, which is adapted to extend through this axial duct.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
A conveyor on which apertured workpieces are received one within another for assembly on the conveyor, said conveyor comprising: a plurality of internal links; a plurality of external links; a plurality of bushings interconnecting respective pairs of external and internal links of said conveyor, said bushings having axial ducts therethrough with radially projecting splines extending in the axial direction of said ducts; a plurality of cylindrical mandrels having splines extending longitudinally thereof, each mandrel including a longitudinal portion of external shape substantially complementary to that of said axial duct of said bushing; each of said mandrels further including a tail portion adapted to extend through respective apertures provided in said workpieces being assembled; said mandrels being at least partially received within said axial ducts of the respective of said bushings, and being in splined engagement therewith so that said mandrels are rotatably coupled with said bushings while being axially displaceable relative to said links of said conveyor.
Claim 2
Dependent Claim
157 words
A conveyor on which apertured workpieces are received one within another for assembly on the conveyor, said conveyor comprising: a plurality of internal links; a plurality of external links; a plurality of bushings interconnecting respective pairs of external and internal links of said conveyor, said bushings having axial ducts therethrough with radially projecting splines extending in the axial direction of said ducts; a plurality of cylindrical mandrels having splines extending longitudinally thereof, each mandrel including a longitudinal portion of external shape substantially complementary to that of said axial duct of said bushing; each of said mandrels further including a tail portion adapted to extend through respective apertures provided in said workpieces being assembled; said mandrels being at least partially received within said axial ducts of the respective of said bushings, and being in splined engagement therewith so that said mandrels are rotatably coupled with said bushings while being axially displaceable relative to said links of said conveyor.
Claim 3
Dependent Claim
33 words
A conveyor as claimed in claim 1 wherein each said mandrel comprises two longitudinally spaced, projecting portions of different diameter, said tail portion being on the free end of the outer projecting portion.
Claim 4
Dependent Claim
23 words
A conveyor as claimed in claim 2 wherein said splines on the mandrels extend along the length thereof inclusive of said projecting portions.
Claim 5
Dependent Claim
19 words
A conveyor as claimed in claim 1 wherein said tail portion and two longitudinally projecting portions have stepwise-increasing diameters.
Claim 6
Dependent Claim
21 words
A conveyor as claimed in claim 1 wherein said bushings have opposite ends both of which project beyond said external links.
