    to be by position or construction equally as safe as they would be if fenced. The unfenced wheel is shown in Fig. 24, a plated wheel in Fig. 25, but a much better type of guard is that illus- trated in Fig. 26, the guard being extended along the traverse of the rope to protect the nip between it and the wheel. ‘The open- ings in the face of the guard are left only large enough for the free passage of the rope and too small to allow a person’s hand being drawn in. There are other points of danger which are not covered by either the Regulations or by the Agreement and, as accidents are caused by neglect to provide safeguards for them, the following recommendations should be adopted :— (a) Faller wire brackets if placed too near to each other set up a guillotine action when the mule changes over. Finger room. (at least one inch) can easily be secured by seeing that the brackets are properly spaced on the faller rods. ‘The bosses on these brackets should be made so long that it is impossible to place two brackets too near together. (b) The draft wheels and other cogs on the front of the mule.—These wheels are inaccessible when the carriage is out, but not when it isin. Accidents usually occur owing to the operator slipping when piecing up. Guards sufficiently wide to prevent this should be fitted over the cogs as shown in Figs. 27, 28, 29. (c) The quadrant scroll is generally guarded, but the guard is often left too short and does not cover the nip between the scroll and the band. A short guard is shown in Fig. 18; a complete one in Fig. 26. (d) Many serious accidents have been caused by the | accidental movement of the starting handle while some ~ person was either cleaning or doing repairs between the carriage and the roller beam. This danger can to a large extent be obviated by a locking peg on the “‘ stang’’ or setting-on rod. A. suitable lock is shown in Fig. 30. ~ Ring and Throstle Frames.—The Agreement requires that :— (i) All cog wheels shall be securely fenced.—This includes (a) the wheels in the headstock, (6) the draft wheels, and (c) those driving the lifting gear. - (a) On the older types of frames the guards for the head- stock wheels were not carried low enough, leaving them easily accessible and causing frequent. accidents to workers when wiping the frame ends. Efficient guards are now made by all the well-known makers, and are illustrated in Figs. 31, 32.
