    TRANSMISSION MACHINERY AND HOISTS. Pamphlets dealing with the Fencing and Safety Precautions for Transmission Machinery (Safety Pamphlet No. 1)* and with the Protection of Hoists (Safety Pamphlet No. 2)* have been already issued, and they should be consulted with respect to the safeguarding of ‘* mill gearing ’’ and hoists in cotton mills. The Agreements require heavy overhead main driving belts and ropes | to be guarded underneath, but this does not apply to the belt driving a mule nor to the rope race in the engine house. It 1s net intended that these belts and ropes should be left unguarded. In case of mule belts an efficient guard at the back of the head- stock (Fig. 22) affords protection for the belt also; as regards the rope race it is usual to fence the platform, giving access to the ropes, with strong posts and rails, and this is generally sufficient, to protect the ropes also. ‘The Agreements also require that metal fasteners are not to be used for overhead belts, unless the belt. itself is fenced. SPINNING MACHINERY. Mules.—So far as the cotton trade is concerned the Agreement amplifies the Secretary of State’s Regulations for Self-Acting Mules (Appendix I.) and details the improvements which experience has shown to be necessary in guarding backshaft scrolls, faller stops and draw band pulleys. ! The Regulations require that the following parts of a Mule shall be securely fenced ‘‘as far as it is reasonably practicable ’’ :— (i) Backshaft serolls; carrier pulleys; draw band pulleys.— The Agreement requires that ‘‘ The guards for middle backshaft scrolls shall be fitted with flanges to protect the intake of the bands and the side of the scroll. The guards for the middle draw band and carrier pulleys shall be either fixed to the bottom creel board or be so fastened otherwise that they cannot readily be knocked aside. The side pieces of the guard shall be extended inwards far enough to completely guard the nip between the band and the scroll.’’ In order to carry this into effect, a small Committee was appointed to draw up a Specification for these guards to embody the points agreed upon (see Appendix III.). Such specification was necessary owing to the serious accidents: which occurred on mules that were considered to be “‘ guarded.”’ Many of the old guards only partly covered the scroll (Fig. 4), left the projecting gib-headed (or lip) key unprotected, and were easily displaced (Fig. 5). A large number of makers (Appendix. IV.) have designed guards which comply with the Specification; which have been approved. Some of these are shown in Figs. 6. Ae Candid aw, ie, The Regulations apply to all draw band pulleys whether below the scroll, in the mule gate, or on the frame ends. Those below * Prices 3d. and 6d. respectively may be purchased through any Bookseller, or directly from H.M. Stationery Office at the addresses on the cover of this. pamphlet.
