Report on Miscellaneous Implement Awards at Derhy. 623 
A and D can only be hooked together at the angle shown in the 
illustration ; and as the belts run with the open or grooved side 
outwards, it is impossible for the belt to become detached until 
it is taken off the pulley. 
Fig. 22 shows the method of attachment to the belt by the 
sprigs. It will be evident to those who have to do with leather 
or other belts that this simple fastener is most useful and 
efiective, the process which is often so tedious being now 
rapidly performed ; and as the belt can be taken from its work 
to any convenient place whilst the attachment is being made, 
there is much less risk of accident to the operator than when the 
fastening had to be made whilst the strap was in working 
position ; whereas now the hooking of the two ends together at 
the place of work is but a momentary operation and compara- 
tively free from danger. The attachment is very simple and 
easily made. All that is necessary is that the plates should be 
set on the belt square and true to the edges of the same, and 
that the edge should be cut away so as to leave the groove C 
clear. These fasteners run from 1 inch to 6 inches by ^-inch 
gradations, and are priced from 18s. to 78s. per gross. 
A second fastener for stronger belts, suitable for actuating 
from 10- to 100-horse power, described as Bachmann's Patent 
Crocodile's Mouth Belt-fastener, was exhibited. The nature 
of this contrivance will be readily understood by the following 
Figs. 23 and 24. — Illustrations of Bachmann's Patent Crocodile's Mouth 
Belt Fastener.

illustrations : — Fig. 23 shows the under side of the belt, with 
fastener fixed ; Fig. 24 shows the upper side. The mode of 
attachment is by sprigs, just as in the detachable fasteners. 
Sizes range from 3 to 6 inches, and prices from 10s. to 20s. 
per dozen. Like all the other exhibits of Francis Ley, the 
material is malleable cast-iron of excellent temper and quality.
