512 THE COLLIERY GUARDIAN. March 7, 1913 when the jaws are moved, or allowed to fall, into contact with the cable. Fig 1 is an elevation of, say, the back part of the clip with the clipping lever in position; fig. 2 is an e e elevation of, say, the front part of the clip; fig. 3 is a section showing the positions of the parts when the clip is open; and fig. 4 is a section showing the positions of the parts when the clip is closed. (One claim.) 15443 (1912). Iwiprovemcnts in Safety Mechanism for the Winding Gear of Coal Pits and the like. J. F. Staley, of The Laurels, Exhall, near Coventry, Warwickshire, and C. F. Jackson, of The Gables, Bedworth, Warwickshire.— This invention relates to safety mechanism of the type in which a pair of rotating screws are driven from the winding engine and carry travellers which are adapted to actuate the steam valve and brake mechanism through the medium of trip mechanism in the event of overwinding, winding in the wrong direction, or excessive speeds. The apparatus is extremely simple, and it can be reset in a few seconds by the engineman alone, which is an important festure. This is accomplished by providing a single weighted steam valve and brake operating lever which is held out of operation by a single tripping arm, which is tripped directly by the travellers in the case of winding in the wrong direction, and Figs Fi&f FlG2 -Ca -fl is actuated by a pivoted lever of a special type in the event of overwinding, whilst by pivoting the lever referred to to the collar of a governor the same trip lever is moved if the governor collar rises too high owing to excessive winding speeds. Apart from extraneous connections between the weighted lever and the steam valve and brake mechanism, there is only a single operating lever and a single trip device, which results in simplicity and cheapness of manu- facture and ease of resetting. Fig. 1 is a side elevation, fig. 2 a plan, and fig. 3 a transverse vertical section. (Four claims.)
