it, purpose tolerably well when ia motion the pump
when at rest would be subject to continual leakage
or backward flow # the fluid. Mr. Ambrose rowerd
this City has invented and patented pump on this
principle designed for all kinds of ordinary uses, the
chef regularity of which is elastic coating around
the valve or the substitution of ball Of solid rubber
for the ordinary metallic This form Of valve has
been already employed for upward Of year With good
effect, and seems Likely TO prove itself a c,mpeh
remedy or tie evil above n ced. Tie form oil pump

hollow pluneors instead of pistons. Two OF these SUI
gle-aetg pumrs are placed side by side aud worked
alternately BY levers like an ordinary fire engine.

purposes, capable of saving more rapidly and with
much lees attendance than usual and delivering tho
sawed material at any point desired. The wood mv

BENDING SHIP-KEEEs--A newly invented machine
for converting aght timber into shipknoes has re-
Gently been tested in Boston. The trial, we believe,
proved beyond question the great utility of the inyen
ton. straight stick of white oak timber IL fed
long and 10 inches square, after being steamed was
placed in the machine and securely confined on tho
ere side by chain web, and the other by plat
Of non. An end pressure was then applied, andn
lC, minutes the stick was forced through circulu
mod, ond bent 80 that the ends we're at right
angles with each other. The operation was almost
noiseless, although the strain great that Tho
chain web was intensely heated. An examination
OF the timber bent showed no signs of breaking, but
the length Of the stick ON the inside of the was
shortened more than foot; in fact the ibers Of the
wood had been forced together and into each other,
that body of wood equal to IA inches OF the length
of se stick had disappeared. And this to without
weakening the timber in the least, but greatly strength
ening it. The value of the invention is shown by Tie
remark of q ship-builder who was present and vii
messed the bending Of the stick. He said he wouk
willingly pay s75 f. knee like the bent although
tie timber before bending cost less than IS. For
sticks can be easily bent in an hour. The nvenin
can be used for great variety of purposes, such y
the bending of AK. bows, plow-handIes, and whesE
&llits.
