The vibratory movement of the comb-lay for beating up the filling is produced by the action of the cranks upon the toggle connections; and the upward and downward movement of the lay, to produce the entrance of the comb into the warp and its withdrawal therefrom, is produced by the action of the lever upon the grooved cam. The comb, d, is constructed of teeth, which are secured together by a bolt passing through them, and which have their bases of dovetail form to enable them to be secured between a dovetail lip, on the lay, and a dovetail clamping plate, secured to the lay by bolts.
[Fig. CXXIV.] illustrates the method of lifting the journals from below. The journals, of which there are four, are arranged to work in upright fixed guides on the loom framing, d, e, f, g, and are operated by treadles, which are arranged in pairs below, each journal being connected with one pair of treadles by two rods at its opposite ends. These treadles are operated by cams for each pair of treadles and each journal.

[Fig. CXXV.] represents the top view of the “fixed guides” containing the journals. This loom is provided with ten shuttle-boxes, (seven for the revolver, three upright), for each side, and built by the Furbush Machine Company, being a combination of their older carpet loom known as the “Murkland,” and the “Duckworth Carpet Loom.”
