Title: Apparatus for guiding fabrics into stentering machines, mangles, or the like
IPC: D06C3/04
Filed: 1923-03-10
Abstract: 217,296. Durrant, G. March 10, 1923. Tentering.-Fabric is guided into tentering- machines, mangles, &c. by a pair of reciprocating tentering-clips which are adapted to engage the selvages and move away from the centre of the fabric when they are travelling towards the machine to be fed, and to move towards the centre of the fabric on their return movement, means being provided for opening and closing the clips, for adjusting the distance between the clips to suit the fabric being fed, and for adjusting the angle between the paths of travel of the clips and the fabric. The base of each clip is slidably mounted on rods f, Figs. 1 and 2, secured to a bracket e angularly adjustable on a bracket c. The brackets c are slidable on a rod b and are adjusted by a spindle a having right and left hand screw threads engaging in nuts d on the brackets. Each clip is reciprocated on its rods f by a link k operated by a crank-arm i on a spindle rotated by bevel gearing h, m from a shaft n. Each clip has a spring-controlled gripper q, Fig. 3, provided with a projection r adapted to enter a slot s in the clip base when the selvage of the fabric moves from beneath it. When the clip approaches the machine to be fed, an arm X on the clip engages a part 6 on the bracket e and is thereby moved inwardly to open the clip by a rod v pivoted to links t arranged in front of the gripper. At the same time, a catch 2 engages a projection on the upper part of the lever X. On the return movement of the clip. the catch 2 is raised by a piece 5 on the bracket e and allows the gripper to fall into operative position to re-engage the selvage of the fabric.
