RuGGLHys ROTARY sHEARs.-A new tool, known by
the above designation has been lately Introduced for
cutting hi ct metal AID which is ma in sizes adapted
10 tho thin timed sheets or TO the haIfinch
boierplae. One straight and one circular cutter are
enpo, Cd the latter being revolved and slowly moved
forward by tie ai6 of belt acting Ga pulley at one
extremity Of the machine The knives or cutters Of
this machine are sat thai their edges do not come
completely into contact, but only sufficiently near to
ensure the seperati of the sheet. 1t Is 70 md ia
practice with the ordinary lever shears that the cut
invariably peccdes The point Of absolute contact Of
the knives while it falls behind the point where the
latter begin TO press upon the metal. AL sheas com
pei the patclts to slide past each other in the act Of
separation and II il found that the cohesion Of the
metal is Cestroyed II fairly commences thus
10 slide 40 that absolute contact Of the cutting
edges in Ruggless shears would be worse than u5e-
lees. In practice the edges set at distance equs
TO half tle thickness Of the metal to be cut and the
sheets divided with a degree Of accuracy and of
smoothbtss unsurpassed b. any system yet devised.
RLPIAcING CARS oS TRACK S. Park Co1p esq
Of Milwaukee, patented in June last a device for
moving cars, Which, although operating slowly and by
man-pow@ alone, appears to he decided improve.
ment Oh tie usual process for putting on track
again efter a railroad accident. Our first impression
was decidedly unjust, it appearing to possess little
novelty but in practice it has since been demon
srated 10 work with more ease certainty and rap iy
than any other III we except the practice on some of
the coal railroads of jerking tie wrecks unceremon
ously ont OF the way, prefeuing to ssh few csrs
rather tban detain another train for sim gle moment
Coons apparatus consists Of hand SCREWS 30 newhat
like scew jacks, which are made readily applicable
to a common rail- by slipping the clamp oa over the
ends go Il at by placing rail transversey under each
truck ard apply ing the a. each side the car
may be safely lifted without guys, and entirely sup
ported The rails. 10 this situation suitable
small rOttrs being prev ously provided between the
swing beam and the rail, the car may DO readily
moved si6etse by rofe and a small wlndlass fitted
on an tho Of each. The great difficulty arising from
the Opposition of the trucks to swivel about on their
ceners IS completely avoiaed by this proce.s but in
be required by the cicqmsi ances it may he given by
bending he rail before scicwug up. The invention
is exhibition az the Ibutyfst street depot of
The Hudson River road.
ADAMS, CAR-srRING "A most compact, cheap, elias
tic and evidently durable spring, has been lately
patent by Mr. Adams Of this city, AID is row in
course Of successful experiment 70 more of our
principal railroads. The material s steel and cast
iron, and The whole is designed 70 unite the valuable
properties of the steel elliptic with the compacne5s Of
tbs rubber 4pIIg.
NJ a. employs simply discs circular pieces Of
cast steel, between which he lays circular plates o.
cast iron The latter are alternately convex aud con-
cave; tia. first thick 81 the edge and next thckcst
in the midc e, the whole being confined within
of cast iron. THIS the weight of the car is continually
striving 10 bend each ate into slightly dishiDg form,
and the elasticity an strength proportioDsd 70
The degree Of curvature that they may be compressed
10 fair bearing before the plate Of steel will be so
much distorted as to receive permanent "se,. In
case however such ali event should oc ,ur aud thSt
one or OF the plates in series should become
permanently dshed, the only result will be 10 carry
the csr somewhat sitter until at proper time the
springs can be removed when few skllfd bows
bring il into its original hst condition.
One great point in this spring ia the ease with which |
it msy be ightened or strengthened at pleasure to
adapt to any kind of csr or to any situation desired
ghe case which is merely cyliader open st the
base msy be made to cor tain stiff or easy spring by
iucIessitg diminishing the number OF steel discs be-
tween each alternate cast iron pate The springs |
now in use ae about five inches in diameter outside
the and siV inches hiCh when extended. A
