Abstract
In a chain disc-type compound dobby machine, flexible instruction receiving members are integrally fixed to supporting hooks for decreasing the weight and the moment of inertia of the moving parts so that the connecting and detaching action of the hooks may be securely and easily performed. Moreover the number of parts is reduced and the structure becomes simple while at the same time effecting a stable high speed operation of the dobby machine.
Claims9
A hook connecting apparatus of the chain disc-type as used in a compound dobby machine, comprising pivotally mounted supporting hooks, biasing means biasing said supporting hooks for pivotal movement in one rotational direction, reciprocally mounted hooks adapted to engage said supporting hooks, elongated flexible instruction receiving members each having one end portion secured to said supporting hook and an opposite end portion projecting from said supporting hook to thereby define a unitized pivotal structure having a flexible projection, and instruction means operable to engage said flexible projection of said flexible instruction receiving members to effect rotation of said supporting hooks in a direction opposite to said one rotational direction, said supporting hooks being biased in said opposite rotational direction by the engagement of said flexible instruction receiving members with said instruction means such that said flexible instruction receiving members are thereby operable to effect a biasing connection between said supporting hooks and said reciprocally mounted hooks.
