Abstract

305,512. Rhodes, C. J. Oct. 6, 1927. No Patent granted (Sealing fee not paid). Hollow-ware. - Machines for flanging car bodies and double seaming previously flanged ends thereto comprise one or more pair of oppose( chucks each formed in two parts, relatively dis placeable laterally to permit of flanging, mean: being provided to lock them concentrically during seaming. The chucks of a pair 'are rela tively movable axially and are rotated in the path of adjustable flanging and seaming rollers. Blank feeding and discharging means are provided. In a construction having three pairs of chucks, the chucks are carried by spiders 23, rotated by a casing 14, pinions 17 on the chuck spindles roll ing round a fixed sun wheel 18. The casing is rotated through reduction gearing 8 from a bel pulley. The two spiders are connected by splined sleeves 37 permitting adjustment at 40 according to the length of can body. The chuck, comprise two parts n., b one of which for exampli the part a is centrally secured to its spindle whils the other b is laterally displaceable, drive being maintained by a pin 29 on the part a engaging an enlarged hole in the part b. A conical ended sleeve 26 is secured by a pin passing through a slot in the chuck spindle to a central rod recip rocable by a roller 19 engaging a fixed cam track In the forward position the sleeve 26 locks the part b concentric with the part a. The chucks are advanced and retracted to grip and release the cans by axially moving the bearings by rollers 33 engaging fixed cam tracks. The flanging and seaming rolls 55 are adjustably mounted on bridges 50 spanning beams 48, 49 supported on opposite sides of the machine by pedestals at each end. The cans are supplied to inclined arms 57 from which they are taken by curved arms 58 rotating with the spiders and they are discharged at 59.
