Cotton weaving: its development, principles, and practice . ame, A, mounted upon thevertical cylindrical rods B, which slide in appropriate earsor lugs cast upon the frame. Fig. 124 shows them indetail and detached from the frame ; in fig. 121 they areseen with their connections in their working position. 4th. The batten, A, fig. 125. The batten is somewhatlike the lathe or lay of the old hand-loom both in its con-struction, action, and function. It is composed of twoarms and the block called the cylinder. It has a semi-oscillating movement which would be best described by THE DEVELOPMENT OF THE SHEDDING MOTION. 195 saying that it is equivalent to the half of the movementmade by a clock pendulum. It derives its name from itsfunction of beating back the needles and so putting thehooks out of action as required. It is shown in the frontof fig. 121 with its cylinder, the horizontal block with thenumerous small perforations. This block is not solid buthollow, being built up of four perforated slabs. The battenis a principal feature of the Fig. 125. 5th. The cylinder, fig. 126. This, as just observed, isa part of the batten. Strictly speaking, it is a prism offour sides. Its function is to press back the needles whichgovern the hooks and so put them out of action when theirthreads are not required to be lifted for forming the has four faces, as will be seen from the sectional view intig. 126. It is so actuated as to make one-fourth of a revo-lution with every pick made by the loom, thus bringing itsdifferent faces in successive order into contact with theneedles. If the faces of this cylinder were without the 196 COTTON WEAVING. perforations shown, A a, at each impact every needle in thejacquard would be pressed back and every hook thrownout of action, not a single thread would be lifted, and con-sequently no shed would be formed. It becomes, therefore,a necessity to make the small circular holes in it in orderthat the needle-ends may enter, and the hoo
