WApswoE1H's SFrT-BATLyG tUE-BoAT.-Mr Dan
Tel Ws,sworih Of NewBedford has been recently
exhibiting in tie Fast River e-boat Of bis inyen-
ton for which he claims the property Of freeing tsel
of water in case Of shipping SEQ. Mr.. Wsdsworth's
boat Is handsome cliDch-buit structure, with more
depth and sheer than q common whaeboat, and pro-
vided with alright chambers extending along the
sides, end quite cspacious one be ow the floor or
deck This deck or platform is OF such hight as 70 be
always al or above the level Of the water outside and
several passages are constructed making q communi-
cation between the interior above this deck and the
water outside. 1t is in fact decked boat with very
shallow and empty hold. Covers are provided, by
which these openings, which serve as scuppers, may
be closed If desired. On loading the gunwale with
men md receiving quantity Of wa err the whole
rapidly discharged. The seli-rghtng property pos
By some boats of this kind consider to be OF
roby greater practical importance than self
baiing; but the latter may be Of great value, pro-
yided the former is not sacrificed to attain it.
MooRE's CoAL-HoLE CovER.-Mr. Frederick II.
Moore of Boston patented in April last rather siugu-
lar improvement on The covers of the ordinary coal
hole in our sidewalks, designed to prevent the posi-
bty Of cideDts eitherfrom children falling through
then when n open fer G few minutes or from pedes-
tria1s stumbling over them when loosely fixed.
Moores cover is not exactly removable aid only TO
limited degree liftabe. The upper surface resembles
the OF G. in general use but is under surface is
armed with three vertical rods which descend
though ears in the sides Of the seat. The cover il
provided with ring LET into its top TO form conyen
e1t handle and the hole is opened by raising the
cover bodily to hight Of about three feet, in which
position ii is sustained by catch spring and the
coal or wood to be thrust in sidewse between the
three rods The coal-boe when open resembles half
constructed panot cage an Establishment which may
not he considered particularly ornamental in front of
city mansion, but is decidedly so than the very
AMEs's CoFYIsG MAcHISE.-Mr Nathan Ames of
Saueus, Mas, is the inventor OF "polygraph, or
machine for writing several copies at the same time
The device is simple and ingenious, and consists
mainly Of light wire levers connected together that
whatever motion is given TO one will be com nunicated
TO the others with exact precision In the specimens
now on exhibition at the office of ID. Sheppard, Esq.,
in Wal-st., only two copies are produced, but the
seme principle applies to the production of any num-
Der desired. pen-hande is connected by flexible
Joint the extremity of lever, and the effect is
produced by movement precisely like ordinary
writing. Common gold pens are moloyed, aud ink
il taken at intervals in the usual way, a sufficient
number Of inkstands being suitably located for sup
plying both or all the pens by the movement
All the praccaldificulties ae admirably surmounted
and pefect copies produced with the utmost ease
DE GUIsoSs STORM AscHoR-Mr. Richard V. De
Guinon of Brooklyn has patented within a Few weeks
last passed, very simple and obvious improvement
on or rather attachment to the common ships anchor,
de signed TO give it better holding power in muddy
or quicksapdy bottom. The chief characteristic of
an anchor like that of the misers SOUL is it, tenacious
hold on things of earth, and siDgularly enough
its seadfast character in this respect has made il
since the days Of st. Paul an emblem of the chris
tians hope II is from its form, weight and area
alone that il derives this character, the mud
" look being one Of those devices which cannot
well be attended 70 and guided by hand when al
work in its bIiny bed. The ordinary form has been
found by both theory and experiment best adapted to
JenetIate and hold in every variety OF bottom. The
Aukes are armed with broad thin palms, but these
canrot with safety be extended beyond cert4n de-
gree from the increased liability TO damage in case of
being TANNED and twisted among rocks. In short, the
present anchor is a compromise between the forms
bts adapted TO a rocky or tough cayey bottom and
that best formed 10 hold in loose and treacherous
earth NJ. De Guinons invention makes the anchor
Unstable by adapting il TO receive two very broad
shove-ike plates Of thin wrought iron with conven-
lent fastenings that they may be attached or dis
connected at pleas ure forming when in place an in
mense scrsper, somewhat resembling expanded
umbrella. Experiment only can decide whether this
device will or will not accomplish the greatNesdera-
tum of holding in bad anchorage butt certainly PROM
ises well, and the inventor has taken the precaution
to patent il in several foreign counties. The attach
meIts are held in place by the aid of collar the
shank, a strap passing round the point of the auke
and by several bolts which pass through projecting
ears on their joining edges. The place OF these bolts
nigh; probably be better supplied by clip ring as
making far stronger connection, but this is all mat
ter Of unimpoTtant detail For an anchor weighing
600 lbs the attachments are to be three fourth inch
thick st the center Fourth inch thick at the eIte
rior edges, and weigh with their asenings 400 lbs.
Several braces extending from suitable points in their
surfaces 70 point near the head of the shank con-
tribute very much to strengthen the structure and
additional rope chain is attached to an eye at the
4 4. Il.
any material which il may bring up from the bottom
