Prominent in this respect as ais, perhaps 10 other
more deserving qualities, may be named stone
dressr machine for removing the material or IN fast
for planning the surface by alternately and very rapidly
"peckiDg" tbereat with q tesies OF chisels. The
cbises sie ragged side by side, go that their edges
make continuous line, and are touched at their backs
by cams or teeth s stout hoizonta cyiin er. The
store is fed up on a movable bed or table aud the
reduction progresses at rapid rate. In case Oh
breakage OF other injury to toe chise 1t Is immed-
a,ely rep aced and the machine appears really one Oh
IA most practicable for the purpose which has yet
been introduced. Ore of the sze lately at work
in Canada is Represented as cutting surface six feet
long in ore minute the breadth OF the cutting ecges
being two feet.
Btamble's automatic grain-scale attracts the next
largest group of visitors. The whole apparatus as e.
hibi,ea includes in fact al elevator 10 continual y
carry I'D the grain to reservoir bin, as well as the
me assuring apparatus for letting it down. The inst
process, the eievatpg requires steam power but the
latter the uIng, does not, the wnole movement
being effected in this BY the gravity OF he de-
scendiI grain. This machine weighs of the grain,
indicating the amount by dial, and may be set to
weigh any desired number Of bushe g. stopping itself
when the number i. completed. The whoe at ar
is extremely simple, containing no cello ,te members
except in the scale.beam where the weight is indi
Gated The quantity weighed at each draft ls three
bushels, and five rsfts taken per minute so that
il is practicable to weigh of with accuracy nine hun
dred burhes per hour.
The point wherein this scale differs from all other
attempts by the and other inventors Is in check
ing tie flow of grain before the weight Is completed.
II has been fouAd that large stream OF grain rushing
with rspidty into any scale, exers considerable
force by its momentum in addition to its gravity and
j, is difficult to calculate and compensate for this IN
hueuce. The present scale receives the grain in a
large stream until the proper weight is nearly attained
then by closing the principal gate and receiving
small stream finishes the operation with all the nicely
desired.
rope machine by the Troy Patent Cordage COM
papy proposes to manufacture all kinds of cordsge
and email rope without the necessity OF extending the
strands before laying them together. The necessity
for great length in rope manufact res Is directly and
indirectly, great of annoyance, but the pre-
else point in which this differs from other attempts to
avoid the evil is somewhat obscure Suffice that the
machine lays up cordage in excellent style, putting
strsight rope in the center if desired
The cordsge mace on the machine exhibited con-
tans ole hundred and niDetytwo strands, al equally
cd. The ropes raade on the machine vary In
size from small cords up TO ono and quarter inshes
in diameter.
pair of ponderous machine punches and shears,
from Erie, Ps., are among the best mschinlse and
boiler makers' tools they include an attachment
80 convenient and servicesble as to add much to their
value. This is slight handle for stopping, or rather
for starting the motion. The toggle levers which work
the punch are Of such length that wedge-like piece
is required to nserpose between them and the head OF
the punch in order to render the movement effective.
A smsK hand-lever con 'rols this wedge, keeping it
constantly Withdrawn except when touched by the
operstor The result is that the workman takes q
much time as be pesies in adjusting the metal to be
punched instead Of placing it hurriedy and often
impeifectly as in the old PLAN The same system is
applied to the shears, although there appears to be
less absolute necessity for occasional delay cutting
than in punching.

some fifteen ortwenty inches square which is furnished
for the purpose by the manufacturers.
There is much smaller show Of pumps than usual
in fact the long arrays Of rotary and other devices
for this purpose which formerly transformed this por.
ton of the Crystal Palace into miniature leave Of
" the vinds,' seem to have entirely disappeared and
there are scarcely pumps enough in the Building to
supply one water cure establishment Even the steam
