Our invention relates to textile machines, and
more particularly to an electrically operated stop
motion for a warping or beaming plant,
One object of our invention is to improve upon
the electrically operated stop motion for warp
ing or beaming plants as now ordinarily made.
Our invention consists in certain novel features
of an electrically operated stop motion as will be

or drop needles not shown in Fig. 1. The control
needles or drop needles are diagrammatically in

row of such needles is arranged on each of the
twenty arms 32a, 32b, 32c, . . . 3% of the frame
