drum at the side which carries the ring H, and they are all free to slide in guides formed to receive them in the end of the drum. They are further connected to the drum by coiled springs g', and adjusting screwed hooys 9., which are passed through lugs cast on the boss of the drum and made fast by nuts 98, and it is by the tension of the springs g that the radial wedges are drawn inwards, and thus caused to secure the bars C in position; the con. tact surfaces of each wedge and wedging bar are ribbed to prevent the wedge from slipping back. It will now be understood that as the bers are pressed forward to secure the books of silk waste, the wedges will follow up the motion of the bars, and the ribbed contact surfaces of the wedges will effectually secure every advance made by the barg.

To facilitate the release of the books for the purpose of replacing them by others an adjustabla cam-shaped bar K is fixed to the inner face of one of the side frames for the purpose of thrusting out the radial wedges G as they are severally brought roand in contact therewith. This bar acts upon the wedges after the books of silk have passed under the operation of the several endless bands of dressing surfaces, and thus unlocks the wedge bars C', leaving them free to be slidden back endwise, and thus re. move the clamping pressure from the books. In order to ease the friction of the radial wedges against the bar K, the bars are fitted with bowles at their inner ends, as shown at fig. 1. To effect the automatio release of the wedging bars an inclined plane L is fixed to a bracket on the main framing in such a position as to act upon the ends of the wedging bars, and slide them back towards the side of the machine where the weighted incline D is situated. The books of dressed silk may then be taken out and replaced by books of silk requiring the like operation.

MANCHESTER BOILER ASSOCIATION. THE last ordinary monthly meeting of the executive committee of this association was

( held at the offices, 41, Corporation-street, Manchester, on Tuesday, January 8, Hugh Mason, Esq., of Ashton-under-Lyne, vice-president, in the chair, when Mr. L. E. Fletcher, chief engi. neer, presented his report, of which the follow. ing is an abstract :-During the last month 333 engines have been examined, and 577 boilers, as well as one of the latter tested by hydraulio pressure. Of the boiler examinations, 388 have been external, 7 internal, and 182 entire. In the boilers examined 79 defects have been discovered, 7 of those being dangerous. During the past month there have been seven explosions, by which five persons were killed and fifteen others the explosion had occurred, in order to report to débris scattered in every direction, the dismantled injured. On referring to the following statement him thereon, when, on making an examination, moulding at the top of the chimney stack showing of explosions it will be seen that the highest pro.
