not fixed, but has a pivot in each end, by means of which the bar may have a kind of 

 oscillatory motion on these pivots. Two frames of iron support this bar ; that in 

 which it oscillates being nearly vertical, but inclined a little towards the other needles. 

 Fig. 1165, which is a profile elevation, will serve to illustrate the relative position of 

 each bar to the other. The lower or horizontal frame, the ends only of which can be seen 

 in jig. 1161, under a a, appears in profile in jig. 1165, where it is distinguished by d. 

 The vertical frame at a is attached to this by two centre-screws, which serve as joints 

 for it to move in. On the top of this frame is the rib-needle bar at /, in jigs. 1155 

 and 1165, and one needle is represented in jig. 1165 at /. At g is a small presser, to 

 shut the barbs of the rib-needles, in the same manner as the large one does those of 

 the frame. At h is one of the frame needles, to show the relative position of the one 

 set to the other. The whole of the rib-bar is not fitted with needles like the other ; 

 for here needles are only placed where ribs or stripes are to be formed, the intervals 

 being filled up with blank leads, that is to say, with sockets of the same shape as the 

 others, but without needles ; being merely designed to fill the bar and preserve the 

 intervals. Two small handles depend from the needle bar, by which the oscillatory 

 motion upon the upper centres is given. The rising and sinking motion is communi-
