Abstract
The deflection beam is mounted independently of the tensioning beam to permit raising and lowering of the deflection beam when mounting a warp beam on the loom. The deflection beam is mounted on a support which is secured to a support beam via a detachable clamp connection. A pivotally mounted roller lever which rides on a cam track on the support is used for raising and lowering the support and deflection beam.
Claims11
In a loom, the combination comprising
- a frame having means for mounting a warp beam thereon;
- a tensioning beam mounted on said frame for imparting tension to a plurality of warp threads passing from a warp beam;
- a deflection beam mounted on said frame upstream of said tensioning beam relative to the warp threads passing from the warp beam;
- and
- means mounted on said frame for moving said deflection beam to adjust said deflection beam independently relative to said tensioning beam.

In a loom, the combination comprising
- a frame having means for mounting a warp beam thereon;
- a support arm mounted on said frame;
- a tensioning beam mounted on said support arm for imparting tension to a plurality of warp threads passing from a warp beam;
- a deflection beam mounted on said support arm upstream of said tensioning beam relative to the warp threads passing from the warp beam;
- and
- means for adjusting said deflection beam relative to said tensioning beam, said means including a support having said deflection beam mounted thereon and being selectively rotatably mounted relative to said support arm, a cam track on said support and a movably mounted roller lever for movement along said track to raise and lower said support releative to said support arm.

In a loom, the combination comprising
- a frame having means for mounting a warp beam thereon;
- a support arm mounted on said frame;
- a support beam mounted on said support arm;
- a tensioning beam mounted on said support beam for imparting tension to a plurality of warp threads passing from a warp beam;
- a deflection beam upstream of said tensioning beam relative to the warp threads passing from the warp beam;
- and
- means for adjusting said deflection beam relative to said tensioning beam, said means including a support secured to said support beam for relative rotation thereto, said support having said deflection beam mounted thereon and a fulcrum coincident with the axis of said support beam.

In a loom, the combination comprising
- a frame;
- a wrap stop motion mounted on said frame;
- a warp beam mounted on said frame for supplying warp threads to said warp stop motion;
- a tensioning beam mounted on said frame above the axis of said warp beam and between said warp beam and said stop motion for imparting tension to a plurality of warp threads passing from said warp beam to said stop motion;
- a deflection beam mounted on said frame above said axis of said warp beam and between said warp beam and said tensioning beam to deflect the warp threads passing from said warp beam to said stop motion;
- and
- means mounted on said frame for moving said deflection beam to adjust said deflection beam independently relative to said tensioning beam and permit raising of said deflection beam away from said axis of said warp beam without raising said tensioning beam.
