Planing. - A machine for re-shaping worn loom shuttles comprises a planing-cutter 3 for dressing the sides and a grinding- disk 4 for re-shaping the ends, and a support for presenting the shuttles to the planing-tools. In the construction shown in Fig. 1, the shuttle W is supported by its pointed ends between a pair of brackets 11 carried by a slide 10 whereby it is traversed in contact with the cutter. The slide 10 is mounted in a transverse slide 8 actuated by a handle 9 to feed the shuttle to the cutter. A member 16 adjustably clamped to the slide 10 has its ends 16', 16" upstanding at different angles to its base, and either end is secured in contact with the shuttle to prevent it from rotating and to hold it at the required angle. The height of the shuttle is adjusted by a hand-wheel H. In the construction shown in Fig. 4, the cutter 21 is cylindrical and cuts the shuttle from above, the shuttle being held at the required angle by an interchangeable plate 20 mounted on a vertically adjustable bracket 19. The Specification as open to inspection under Sect. 91 (3) (a) describes also a further modification, in which the plate 20 is mounted on a crank which is rotated to set the plate against the shuttle and is then clamped. This subject-matter does not appear in the Specification as accepted.
