Wire Ropeway.

Mr.. EDIToR, The system of transporting
material by means of an endless travelling wire
rope has been well and thoroughly tested during
the past ten years (lO) under a variety of circum-
stances which have proved its economy, simpli-
city and advantages.
The Endless Ropeway'' introduced in the
year 1871 by Mr.. Hallidie has been in operation
for ten years 00) and proved itself in every way
the most reliable, economical and simple mode
of conveying material of all descriptions that
can be conveyed in reasonable sized packages.
The principles of its operations will bear the
s~trictest criticism, and an examination of the
same by skilled and scientific mechanics will de-
monstrate the great advantages over the many
methods now in operation for similar purposes.
Its mode of operation may be briefly summed
as follows IAN endless wire rope is supported
ut intervals of from $50 feet or more on grooved
wheels or sheaves. which are secured to the
ends of cross rms elevated on suitable posts or
towers about sixteen (l6) feet above surface OBJ
structions of the ground. The bights of the
endless rope are placed around end sheaves, or
grip pulleys, placed horizontally, one at each
extremity of the line.
The endless rope is thus passed around hori-
zontal end sheaves or grip pulleys, and is sup
ported between these end sheaves ut proper inter
walls, on beaming sheaves of such proportions that
the friction is reducad to a minimum. The office of
the end or grip pulley is to transmit power to or
from the endless rope, So that the rope cannot
slip in the grooves of the pulley and the speed
of the rope can be regulated byit. The conyeyers
or carriers used for moving the material, the

the material to be moved and attached to the
rope by means of steel clips of peculiar form at
distances regulated by amount of material to
be removed.
1t will be seen that when the rope is set in
motion, either by gravitation or other motive
power, the rope moving mt an uniform rate of
speed of about two hundred (20O) feet per min
ute. IL will carry with 1t the conyeyers, which
can be loaded as they pass, and at the point of
of discharge are unlOaded automatically.
In the adaptation of this system for trans
porting canes, that portion of the line required
for loading, is brought to within easy reach of
the persons who place the canes in the contain
ers as they pass. BY placing the containers
fifty (50) feet npart-each containing two hun
dred (2OO) pounds there will be delivered every
minute eight hundred $500 pounds or twenty
four (24) tons per hour, or two hundred and
forty (24Oi tons in ten (l0) hours.
When the point of discharge is lower than the
point of loading the ropeway will run by gravi-
tation if the angle of descent exceeds eight o.
degrees.
Special necessities exist for the use of the
Hallidie system in all countries where the
obstacles TO railroads or other methods are diff
cult to overcome. or when a cheap and certain
line Of transport is required TO work at all times
and is not effected by heat, cold, or rains. 4

approaching You the other is receding you, and
can be so arranged, moving in any direction,
turning any angle and virtually serving the same
fssOse as two ~ miles of any other means of
ro~peTa&tion. In other words, in a mile of
in length. Id, the rope is in reality too miles
