Abstract: An automatic gear shifting device for multi-speed bicycles. According to the invention, the device comprises a centrifugal force gear shifting mechanism which is controlled by the pedaling cadence of the rider. Pedal crankshaft speed is transferred to a main unit which contains an axially mounted drive shaft. Flyweights which are pivotally affixed to the drive shaft by an inner sleeve engage the housing thread members once a rider pedals outside of a predetermined cadence range. Engagement of the threaded members causes the inner sleeve to move one position. A cam follower affixed to the inner sleeve thereafter causes rotation of an outer ring, the outer ring having upshift and downshift cable attached to it. Movement of the cable causes rotation of a cable drum which is pivotally mounted to a derailleur. Movement of the cable ring drum causes the derailleur to shift gears. Also provided is a means to adjust the cadence range.

Abstract: A method and apparatus are provided for printing individual metal body blanks, from which three piece container bodies are formed, in a multi-colored image on an individual body blank basis. Individual body blanks are cut from a sheet and fed in two parallel streams to the rotating impression cylinder of a multi-color off-set litho press. The body blanks are secured to the impression cylinder using mechanical clamps and magnets and are rotated sequentially past a number of inking unit/ultraviolet lamp pairs. As each color ink is applied by an inking unit, it is immediately cured by an adjacent ultraviolet lamp before the body blank is transported to the next inking unit.

Abstract: An easy opening can and key combination, wherein the can has a circumferential score encircling the can body beneath the double seam attaching the body to the end member, the key comprising a handle having a jaw at one end with inner and outer jaw elements embracing the seam, the outer element extending below the seam and having an end alignable with the score in a position such that when the handle is pressed downwardly it swings about the seam and the outer jaw member ruptures the score whereupon the tool is swung laterally and slightly upwardly separating the upper portion of the can from the body.

Abstract: Apparatus and method for implanting a sizing disc into an open unshirred end of a shirred tubular casing wherein the sizing disc has a larger periphery than the unstretched inner periphery of the unshirred end of the casing.

Abstract: This disclosure relates to a machine for receiving can bodies and automatically outwardly expanding the same to a decorative predetermined contour. The machine includes special transfer means for positioning can bodies on and removing can bodies from supports moving in a convex arcuate path, the transfer device including a turret member mounted for rotation about a fixed axis, a plurality of article carriers pivotally carried by the turret member for movement therewith in a generally circular path, and control means for controlling the contour of a portion of the generally circular path to be coincident with a portion of the arcuate path.

Abstract: An improved can end trimmer provides for positioning a trimming knife on a rotating spindle in a manner such that it may be adjusted to proper alignment with another knife by means of a spacer fitting. The invention further allows for the removal or replacement of the trimming knives without the necessity of alignment adjustments.
