One of the more common forms is shown in figure 40. 
The hooks, A, are bolted to the side of the bucket and sup- 
port the bail. A one-half. inch band of iron, B, holds the 
bottom in shape, and forms a support for the hinge to rest 
upon.’ The bottom, C, has the axle, D, fastened to it by the 
strips, #. ‘The ends of the axle pass through the sides of the 
bucket and rest upon the band, B. The axle is placed to one 
side of the bottom, C, so that, when it is free to fall, it will 
hang vertically. The strap, /, extends just to the edge of the 
bottom, and is fastened to the same to protect it from be- 
ing torn by the latch, H. The latch is made of steel and is 
riveted to the bucket at the upper end. It is surrounded by 
a loop, K,in the band, B, which protects it and allows it to be 
drawn out, thus freeing the bottom, C. The height of this 
form of bucket is 45 feet, while the diameter is thirty-two 
inches.
