CHARLES P. IACOWITZKY, OF CORPUS CHRISTI, TEXAS.
IMPROVEMENT IN THE PROPULSION OF VESSELS.
Specification forming part of Letters Patent No. 14G,009, dated Doemaber 30, 1873; application filed
Anugust 23, 1873.To all whom it may concern:
Be it known that I, CHARLES P. IMACOW-
ITZKY, of Corpus Christi, in the county of
Nueces and State of Texas, have invented a
new and useful Improvement in Vibrating
Propellers, of which the following is a specifi-
cation :
Figure 1 is a detail longitudinal section of
my improved device. Fig. 2 represents an ar-
rangement of the device to adapt it to produce
a continued action of the paddles upon the
water, and for attachment to a line of boats.
Fig. 3 shows the mode of pivoting or suspend-
ing the paddles.
Similar letters of reference indicate corre-
sponding parts.
lMy invention has for its object to improve
the construction of tle device-for which Let-
ters Patent No. 135,994 were granted to me
February 18, 1873, so as to make it simpler in
construction, more convenient in use, more
readily adjusted and controlled, and more
effective in operation.
The invention consists in the combination
of the sleeve or socket, made smooth upon one
end, and threaded upon the other, and the
square rod, with the arms, the sliding frame
or plate, the rack-bar, the gear-wheels or seg-
ments, and the pivoted paddles, as hereinafter
fully described.
A represents the piston-rod of a steam-en-
gine, which rod is secured to or connected with
an arm, B. The arm B passes through a slot
in the bottom or side of the vessel, through a
slot in the sliding frame or plate G, and is rig-
idly attached to or formed solid upon the rack-
bar C. The rack-bar C is securely connected
with and slides upon the plate or frame G. The
teeth of the rack-bar C meshintothe teeth of the
small gear-wheel or segment of a gear-wheel,
D, attached to or formed upon the base of the
paddle E, so that the said paddle may be pro-
jected andwithdrawn by the movements of the
said rack-bar C. The paddles E are pivoted
to the sliding plate or frame G, so that they
may be carried back and forth by and with
said frame or plate in its movements. To the
sliding plate or frame 0 is rigidly attached an
arm, F, which projects upward parallel with and
at alittle distance from the arm B. H is a sleeve
or socket, which has a screw-thread formedupon one-half of its length, and the other half
is left smooth. The smooth part of the sleeve
II passes through a smooth hole in the upper
part of the arm F, and the threaded part screws
into a screw-hole in the upper part of the arm
B. The sleeve H has flanges, nuts, or other
stops upon its ends and center, to limit the
movements of the said sleeve Hin said arms B F.
By this construction the arm B and rack-bar
C will be first moved to adjust the paddles, and
the rack-bar, paddles, and arms will then be
moved together to make the stroke. I is a
square rod, which passes through a square
hole formed longitudinally in the sleeve IT.
By this construction, by turning the sleeve H
by means of the square rod I, the arms B F,
the sliding frame or plate G, and the rack-bar
C will be so adjusted, with respect to each
other and the piston-rod A, that the paddles
E will be projected upon the forward or back
stroke, as may be desired. The square rod I
is turned to adjust the paddles E by a crank,
J, a screw, or other convenient device.
If desired, two or more sets of the arms B F,
sliding frame G, rack-bar C, and paddles D E
may be applied to the same boat, the arms B
being connected by an endless chain, which
passes around pulleys pivoted to fixed sup-
ports attached to the boat. In this case, one
of the arms B is attached to the upper part of
the said endless chain, and the other to the
lower part. By this arrangement one set of
paddles will be projected to operate upon the
water at each movement of the piston-rod A,
so as to keep a set of paddles always operating
upon the water. In propelling a train of boats
theyareplaced end to end, and in line with each
other, and are connected by endless chains,
which are operated by the piston, as hereiu
before described. In this ease all the boats of
the train, or only a part of them, may be pro-
vided with one or more sets of the propelling
device, as may be desired.
An engine and set or sets of the propelling
device may be placed at each side of the boat;
and made entirely independent of each other,
so that they may work together or separately,
thus greatly facilitating the operatioi of turn-
ing and guiding the boat or boats. The rack--
bar C may, if desired, be made double, so as to
operate two sets of paddles. The paddles
