398,539. Guiding and supporting shuttles in looms. SHIMWELL, O., Gawsworth Old Hall, Gawsworth, Chester. March 16, 1932, Nos. 7794 and 8081. [Classes 142 (ii) and 142 (iii).] Reeds; shuttle and like guards ; shuttle races ; shuttles.-The shuttle is controlled during its flight by means of blades, fingers or the like which are rigidly mounted on the slay and are adapted to pass between the warp threads, the blades causing the shuttle to ride upon the slay, without touching the warp threads, and against the reed but permitting the shuttle to be withdrawn by lateral movement on displacement of the reed. In the construction shown in Figs. 1 and 2, the shuttle d is formed with an undercut groove g to accommodate correspondingly shaped blades m on a rigidly mounted sole plate k, an additional set of fingers q being provided to hold the shuttle against the reed and reduce the pressure of the pointed blade-ends m<1> on the shuttle. Alternatively an ungrooved shuttle may be held clear of the warp threads by projections k<1>, Fig. 4, against which it is held by arms 25 carried by a hinged plate 26 or by projections on the reed dents engaging a correspondingly shaped recess in the shuttle. Two or more fabrics or plies, looms specially designed for.-In the application of the invention to looms for weaving two connected superposed fabrics, which can be cut to produce warp pile fabrics, an additional set of blades is provided on the slay cap to guide and support the upper shuttle. In a modification for looms for weaving two separate fabrics, the upper shuttle is supported on a second shuttle race constructed similarly to the lower one. Shuttle-boxes.-The shuttle can be withdrawn from the box by turning a handle y, Fig. 8, and withdrawing locking bolts x from eye bolts w to permit the turning back of a hinged wall t.
