English Abstract

A bio catcher has a comb or rake like device attached to the front of a boat and which can be adjusted to more selectively collect a variety of bio matter, most notably aquatic plants. The device can either push away plants, collect those just at the surface or collect several inches below the surface. Additionaly, a trimmer can be fitted in front of the comb to cut the plants that will then be collected by the comb. In combination with a flat bottom boat and a movable propeller requiring very little depth to operate in, it is possible to use the device in as little as 6 inches of water.


French Abstract

Ramasse-plantes aquatiques muni d'un dispositif ressemblant à un peigne ou à un râteau fixé à l'avant d'un bateau pouvant être ajusté de manière à recueillir de façon plus sélective une variété de matières biologiques, plus précisément des plantes aquatiques. L'appareil peut soit repousser des plantes et ne recueillir que celles qui se trouvent à la surface ou recueillir des plantes sur une profondeur de plusieurs pouces sous la surface. De plus, il est possible de fixer des ciseaux à l'avant du peigne pour couper les plantes qui seront ensuite recueillies par le peigne. En combinaison avec un bateau à fond plat et une hélice amovible pouvant fonctionner en eau très peu profonde, il est possible d'utiliser cet appareil dans aussi peu que 6 pouces d'eau.

Field of the invention ;

The invention relates generally to skimmers and collectors but more
parkicularly to a
collector of aquatic plants and related bio matter on the water surFace.

Background of the irwention :

A number of inventions decribe riettings and other such catch-all collectors
designed
to collect water surface borne debris but they are often designed for trash
and such
debris. Other systems are really underwater weed wackers and have a rather
aggressive approach to the elimination of aquatic plants and can produce
severe
collateral damage.

There is therefore a need for a less aggressive device to handle the removal
of
aquatic plants on or below the surface of water.

SUMMARY OF T'HE fINVEN71ON

The present invention d'ssdoses a comb or rake like device attached to the
front of a
boat and which can be adjusted to more selectively collect a variety of bio
matter,
most notably aquatic plants. The device can either push away plants, collect
those
just at the surface or collect several inches below the surface. Additionaly,
a trimmer
can be fitted in front of the comb to cut the plants that will then be
collected by the
comb. In combination with a flat bottom boat and a movable propeller rquiring
very
littie depth to operate in, it is possible to use the device in as little as 6
inches of
water.

The foregoing and other objects, features, and advantages of this invention
will
become more readily apparent from the following detailed description of a
prefen-ed
embodiment with reference to the accompanying drawings, wherein the preferred
embodiment of the invention is shown and described, by way of examples. As
will be
realized, the invention is capable of other and different embodiments, and its
several
details are capable of modifcations in various obvious respects, all without
deparbng
from the invention. Accordingly, the drawings and description are to be
regarded as
illustrative in nature, and not as restrictive.

DETAILED DESCRIQ _Z'ION OF THE PREFERRED EMBOD{MENT

A bio catcher (10) is attached to the front of a boat (12) by way of a frame
(14). A
threaded adjustment (16) with a handle (18) can adjust the height of the
skimmer (20)
and both the threaded adjustment (16) and the skimmer (20) are related by way
of an
armature (26). The height of the skimmer (20) can be adjusted from below the
wateriine (22) as in fig. 1, or at the water iine as in fig. 3. The skimmer
(20) has a
plurality of bottom tines (24) along its bottom and side tines (24') along its
sides,
wherein the side tines (24'), situated on each sides of the skimmer (20) are
used for
containing the aquatic plants within the skimmer (20) until they are dumped
off.
Moreover, different configurations can be given to the skimmer (20) to more
selectively collect a variety of aquatic plants by way of changes in length or
spacing of


CA 02473650 2006-06-05

the tines (24). Once collected by the tines (24), the plants are contained by
a screen
(60), which forms an integral part of the bio catcher (10) and which lets
water pass_
The bio catcher (10) can push away plants as in fig. 6; go very deep as in
fig. 4; be
positioned for emptying the skimmer (20) as in fig. 5; fior pushing aquatic
plants or
debns as in fig, 6 , so as to dear a path or pushing bundles of precut plants
so as to
direct them towards the shore or any other suitable location for disposal.
Fig. 7
iiiustrates a configuration suitable for riding the boat (12) without using
the bio catcher
(10), Skimmer moving means (54) are provided for moving the skimmer (20) from
one configuration to the next, generally in the form of a geared electric
motor but
various means such as hydraulically or pnematically actuated means oould be
used
as well.

In the event of hard to manage aquatic plants, an optional firimmer attachment
(30)
can be removably attached in front of the skimmer (20) at a depth and angle of
attack
adapted to the cutting needs of the plants at hand_ The trimmer attachment
(30) is
inspired in shape and function to a hedge tiimmer and is comprised of a
trimmer pivot
and height adjustment means (56) and a trimrner actuator (58), which can be
any
suitable actuating means known in the art.

To cover a larger area with each boat (12) pass, a side skimmer (40) can be
installed
on at least one side of the boat (12), preferably both sides. The side skimmer
(40) is
deployed from a non use configuration as per flg. lb to an intermediate pre
use
conf'igurafion as per fig. 9a by rotating around a vertical pivot (50) so that
the side
skimmer (40) runs parallel to the side of the boat (12), and then into an in
use


CA 02473650 2006-06-05

configuration with an angled deployment as per fig_ 8 by rotating around a
horizontal
pivot (52) wherein a rod (42) for each side skimmer (40) positions the side
skimmer
(40) into a seleGted angle of deployment, which contributes to collecting and
maintaining large bundles of aquatic plants for moving to shore for disposal.
When the
skimmer (20) is in emptying mode as in fig. 5, the boat (12) can ride on top
of the
disposed bundle of aquatic life and the movable propeller (54) can be lifted
ou#, as in
fig. 7c, so that the bundle (not shown) is kept together for later pick-up
along with
other bundles scattered in the area. After the area is cleared, the bundles
are moved,
contained by the side skimmer (40) the screen (60) and, of course, the skimmer
(20).

A single figure which represents the drawing illustrating the invention.
