[Fig. 985.] shows part of a cross section, to explain minutely the mode of winding upon a single bobbin.
[Fig. 986.] is the plan of the parts shown in [fig. 985.]; these two figures being drawn to double the scale of [figs. 983.] and [984.]
A, A, [figs. 983.] and [984.] are the end frames, connected at their tops by a wooden stretcher, or bar-beam, a, which extends through the whole length of the machine; this bar is shown also in [figs. 985.] and [986.]
B, B, are the creels upon each side of the machine, or bobbin bearers, resting upon wooden beams or boards, made fast to the arms or brackets C, about the middle of the frames A.
D, D, are two horizontal iron shafts, which pervade the whole machine, and carry a series of light movable pulleys, called stars, c, c, ([figs. 985], [986.]) which serve to drive the bobbins E, E, whose fixed pulleys rest upon their peripheries, and are therefore turned simply by friction. These bobbins are screwed by swivel nuts e, e, upon spindles, as in the silk engine. Besides the small friction pulley or boss, d, seen best in [fig. 986.], by which they rest upon the star pulleys c, c, a little ratchet wheel f, is attached to the other end of each bobbin. This is also shown by itself at f, in [fig. 987.]
