catches a notch or lug on the iron rods, whilst tbe other is balanced by tbe 
weight of the feed-board. The setting is so delicate that any considerable 
pressure on the feed-board, side-boards, or bonnet depresses the end of the lever, 
thereby raising the opposite end clear of the lug, and thus removing the resist- 
ance to the springs which drive out the rods and slide. The action is very rapid, 
and when the slide has reached the opposite side and come in contact with 
the woodwork below the bonnet, safety is insured. The only element of risk is 
the possibility of the hand or foot being caught by the slide, when the conse- 
quences would be serious. The price is 3/., exclusive of fixings. It will be 
understood that the feed-board is so hinged that any pressure on any part of 
the apparatus, cover, &c., relieves the catch. 
The other guard similarly noticed was shown by P. and H. 
P. Gibbons, of Wantage, and is the invention of E. VV. Pamplin 
and Co. It is described as an improved combined hood and 
platform, and safety-drum shield. The following illustration, 
which shows the guard open for work, will enable the reader to 
understand the mechanism : —

ITie apparatus comprises an adjustable hood a, which is suspended on pivot 
pins in.sertetl in the bearing standards n. The lower end of the hood is 
attached by means of light connecting-rods, c, to liiugcd pivots on the feed- 
boaid, D, and the latter is liung on a trenutlus. A self-acting flafj-board, e, 
is also attached by means of an adjusting chain to the hood on the inside, and 
the " flap-lx)ard " is provided with a toothed rack, F, liaving a small hand 
chain, k', attached as shown. A short connecting link, K, joins the feeding 
board to a ratchet-wheel, g, into the teeth of which an adjustable spring is
