Abstract
Abstract A printing sheet gripping device is disclosed which is attached to the rear edge portion of a printing saddle. The printing sheet as used herein includes the yieldable sheet-like material type, such as a synthetic resin printing sheet. This printing sheet gripping device permits the ready gripping of the printing sheet without removing the saddle from the printing cylinder. This simple operation is enabled by use of the gripping device of a novel construction which consists essentially of a gripping member and a holder, said gripper being adapted to assume a released or open position, when forcing the holder against the saddle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
A printing sheet gripping device affixed to a printing saddle comprising: a. a holding member slidingly attached to one end of said printing saddle, b. a gripping member slidingly attached to the same end of said printing saddle as said holding member; c. a first biasing means between said holding member and said printing saddle to bias said holding member away from said end of said printing saddle and toward said gripping member; d. a second biasing means between said gripping member and said holding member to bias said gripping member toward said holding member, and e. gripper opening means engaging said holding member such that movement of said gripper means overcomes said first biasing means and moves said holding member toward said end of said printing saddle and away from said gripping member.
Claim 2
Dependent Claim
134 words
A printing sheet gripping device affixed to a printing saddle comprising: a. a holding member slidingly attached to one end of said printing saddle, b. a gripping member slidingly attached to the same end of said printing saddle as said holding member; c. a first biasing means between said holding member and said printing saddle to bias said holding member away from said end of said printing saddle and toward said gripping member; d. a second biasing means between said gripping member and said holding member to bias said gripping member toward said holding member, and e. gripper opening means engaging said holding member such that movement of said gripper means overcomes said first biasing means and moves said holding member toward said end of said printing saddle and away from said gripping member.
Claim 3
Dependent Claim
82 words
