Claim 11

A device for fixing a form saddle on a rotary press form cylinder, said device comprising a. hook means mounted in said form cylinder to grip a portion of said form saddle for holding saddle in place on the form cylinder when the hook means is in a clamping position. b. said hook means applying a force on the saddle in only a substantially radial direction with respect to the form cylinder when the hook means is in the clamping position, c. hook mounting means including a spindle having a surface on which said hook means is disposed, d. said spindle being located inside the form cylinder and rotatable about its axis in a displacement range between a clamp producing position and a hook means return position to carry the hook means into and out of the clamping position, e. means for rotating said spindle from outside the form cylinder to move the hook means into and out of the clamping position, and f. a first stop means located on the spindle and a second stop means located on the hook means, g. said first and second stop means being located with respect to each other to come into contact when the hook means does not reach the clamping position thereby preventing the spindle from reaching the clamp producing position.

Claim 12

A device for fixing a form saddle on a rotary press form cylinder, said device comprising a. hook means mounted in said form cylinder to grip a portion of said form saddle for holding saddle in place on the form cylinder when the hook means is in a clamping position. b. said hook means applying a force on the saddle in only a substantially radial direction with respect to the form cylinder when the hook means is in the clamping position, c. hook mounting means including a spindle having a surface on which said hook means is disposed, d. said spindle being located inside the form cylinder and rotatable about its axis in a displacement range between a clamp producing position and a hook means return position to carry the hook means into and out of the clamping position, e. means for rotating said spindle from outside the form cylinder to move the hook means into and out of the clamping position, and f. a first stop means located on the spindle and a second stop means located on the hook means, g. said first and second stop means being located with respect to each other to come into contact when the hook means does not reach the clamping position thereby preventing the spindle from reaching the clamp producing position.

Claim 13

A device for fixing a form saddle on a rotary printing press form cylinder, said device comprising: a. hook means mounted in said form cylinder to grip a portion of said form saddle for holding the saddle in place on the form cylinder when the hook means is in a clamping position, b. said hook means applying a force on the saddle in only a substantially radial direction with respect to the form cylinder when the hook means is in the clamping position, c. said hook means has a hook shank portion, a body portion which includes a circular bore hole and has a displacement range between the clamping position and a resting position, d. hook mounting means located inside the form cylinder to carry the hook means into and out of the clamping position, e. said hook mounting means including a spiNdle having a portion with an eccentric cross-sectional shape; f. said eccentric portion passing through said bore hole in frictional contact therewith, g. said spindle turning about its axis in a displacement range between a clamp producing position and a hook means return position, each of the spindle displacement positions being located beyond the hook means displacement range.

Claim 14
