Improvements in Draw Nets.
1, GEORGE HUGHES, Patent Agent. of 23 Coleman Street, in the County of
London, (a communication from Fr. Schollhass, Merchant, of Bremen), do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The object of my invention is to construct draw nets in which the pole is replaced
by boards (hereinafter called "sheer boards") placed at an angle to the draw net
by particular methods of fastening, and which consequently move at an angle
through the water.
These sheer boards may be either simple boards connected with the draw line in
any suitable manuer (as by bowed pieces of iron) or they may consist of piping or
bent pieces of iron, under which are boat shaped supports to facilitate their
movement, and above which are Hoats to increase the buoyancy of the sheer boards.
In Figs. 1 and 2 of the accompanying drawings two different forms of sheer
boards are shown, and Figs. 3 to 10 show various ways of connecting the sheer
board with the draw line.
The sheer boards a can be connected with the rope t either as shown in Fig. 3
by a fixed rail supported by props 12 and 3 in the lugs c and d, or by the simple
means shown in Fig. 4, the rope being fastened on a bowe at about 3ds the
length of the bow from one of the ends attached to the board a.
In Fig. 5a fixed cross rail is provided which is kept at a distance from the
board a by four props 1, 2, 3 and 4, the rope being connected to the rail fat
the point where props 3 and 4 are attached.
Fig. 6 shows a similar arrangement but the rail is bent and connected with
board a by four props 5, 6, 7, and 8 situated in a line one behind the other, the
rope being fastened at the end of the rail 1.
t
Fig. 9 shows a similar arrangement to Fig. 5 with the difference that in place of
rail, a frame is used, being kept at a distance from a by the four slanting
props 1, 2, 3, 4, the rope being attached to one of the shorter sides of the frame/
In Figs. 1 to 9 the ground net is fastened direct, but in Figs. 7 to 10 use is made
of a spiral spring. Fig. 7 shows an arrangement of hanging to the ropes (by
props 1 and 2) a rail g on which is fastened the swinging lever h, to one end of
which the ropes t and are fastened, while the other end of the lever is held by a
spiral spring. The ropes t' and are passed through the long and narrow slots in
the sheer board, thus securing the angular position of it.
Fig. 10 shows a similar arrangement for the ropes t² and t³ of the ground net,
the rope being fixed at the meeting points of the props 1, 2, 3, 4 of these
props and 3 are twice the length of 2 and 4.
In Fig. 8 the fixing of the rope t to the rail g¹ is effected as in Fig. 3, while the
ropes are fixed to the ground net by a spring i leading through two holes in the
board direct to the ground net.
In place of the sheer boards, I may use pipes or tubes Fig. 1, which are
connected to the rope t by the props 1, 2, 3, and 4 while a boat shaped float y
having an upturned beak enables the contrivance to glide easily through the
water, and the body part is connected with by the rods 5 and 6 and is designed
by its greater buoyancy to counteract the weight of the piper and the boat shaped
part -
The part is preferably made of cork or other light material: or as
Fig. 2 shows, a beut iron sheet may be used which is hemined at the margin and

page_text: cutries a piece of cork or a hollow holy filled with air. A. bont like float ir is
fastened under a to facilitate the gliding of the metal sheet through the water.
The connection with the draw rope is made in the same manner as in Fig. 1.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improvements in draw nets whereby poles are substituted by boards, pipes,
or sheet from plates, which are floated vertically at the sides of the net, and kept
away from one another by the water acting on their surfaces which are placed at
an angle to the rope and to each other, their passage through the water being
facilitated by boat like floats under the boards or the like, the upper part of the
boards or the like being provided with light bodies, or with hollow structures filled
with air, in order to increase the buoyancy of the boards or the like, the whole
substantially as and for the purposes described in the above Specification, and
exemplified in the accompanying drawings.
Dated this 16th day of October 1895.
