HAMILToxs QUARrz-C RI UsHER-Another contribution
has been ADDED the machines which our various con-
gomeraes of rock and metal have called into existence
Mr. james Hamilton of this City has recently constructed
at the Novelty Iron Works QuartzC Crsier apparently
superior in several respects any of its predecessors 1t
has been set in motion the Atlantic Forge where we
have had opportunity Of seeing it in operation In the
construction of this crusher Mr.. H. who is well known
the author of several other valuable Inventions has taken
ihe bold step Of compelling the rock to yield at once
Many or perhaps all Of the crushers already introduced
oIolatc the material by the weight alone OF heavy
mars or by the weight combined with the percnssve et-
feet Of its descent that weight rolls over and tumbes
sb, ut on the Jumps of unit; they are finally disine-
grated. In this machine there is alternative Until
the rulverzaton has reached certain degree of fnsness
Tie reduction of the ny Is certain the results
Of ony Of tho laws of geometry. This bold feature IN
wolves the possibility Of immense strain on the cast
ngs but the proportions such as to provide against ITS
excess cs also TO withstand and overcome IT, however Sc
we're.
The machine consists of but two principal parts which
we will term respectively crusher anu cradle. Ihe
roller or crusher nearly cynd al in FORM anu Is par
tiGly Ievoyed rocked by means OF strong a. m winch
rise om IFS upper side. This crusher is confined IN
cradle Of nearly the sumo form but Of somewhat greater
damoer and fits co,ey at tie ends, So that none OF the
material shoy eed in nas It's O the bottom except ny
the legitimate method Of grinding between the chilled and
corrul ated surfaces of the crlsher and s bed Inc
cru or crushing cylinder is about two feet in diameter
and w feet long and provided witha stout wroughtron
shaft the journals Of which carried in boxes IN the ends
the cradle. These boxes are Tree 20 move up aod oo"

top but diminish nothing at the bottom and the form 0

inch tie whole The cradle supplied with water
by pipe, and the fine material IL continually washing out
through holes the center of the base, the par
TICKS being separated by wire cloth IN the usual way and
subjected to a repetition Of the process.
In This machine the resistance Is comparatively steady
limited quantity Of the broken material u admitted On
each side every oscillation and the machine goes at lts
work with a oarnes,nc- and zeal well worthy of general
imitation. The difference in steam power required 10 ac-

in the amount of friction and collateral resist

tm, Hamilton may be safely considered far in advance
oi ol previous efforts.
