Improvements in Landing Nets.
We ARTHUR THOMAS ALLCOCK, Engineer and DAVID SLATER, Fishing Tackle
Maker both of Newark upon Trent in the County of Nottingham do hereby declare the
natare of our said invention to be as follows:-
Our Invention has for its object Improvements in what are known as Collapsing
Rings for Landing Nets" and refers particularly to the method of securing the sides
of such rings to the handle, so that they may be taken apart for convenience of carriage,
when not in use.
To carry out our Invention we form beyond the screw, which serves to attach the
net to the handle, a square or polygonal shank terminating in a projecting head,
which is made with two inclined recesses forming an inverted wedge.
Upon the square shank is a sliding collar having a pocket or recess on either side
corresponding to the recessed faces on the head. A nut on the screw can traverse the
collar up the shank. The two sides of the ring are formed of flexible material such as
wood, whalebone, or steel, and they may be either jointed together in the centre to
form a balloon shaped ring, or have their outer ends fastened together with a cord or
wire to form a triangular shaped ring, in any of the usual methods.
The inner ends of the sides fit and drop into the pockets or recesses formed for them
on the sliding collar, and are further held by the recessed faces at the wedge shaped
head.
Upon screwing up the nut the sliding collar is forced towards the head, and the
sides of the ring sliding up the inclined faces of the head are expanded and pressed
outwards, until the whole forms one rigid frame.
When the nut is unscrewed the collar and sides slide down away from the head and
the whole arrangement collapses. The sides can then be withdrawn from the head
and collar and folded up with the net for packing away.
In a modification of this arrangement the collar with its two pockets or recesses for
the sides may be made fast to the shank, and the wedge shaped head made to slide
towards it. The screw and nut in this case being on the outer side of the shank from
the handle.
For large and heavy nets we joint the two recessed armis, forming the wedge shaped
head, to the shank, so that they may turn in a horizontal direction parallel with the
sides of the net. Stops are formed on the sides of the net against which the jointed
arms bear, so forming a toggle joint; which, upon the nut being screwed up expands
the sides of the net in a powerful manner, and avoids friction, as the sides have not to
slide in the recesses of the head.
Another modification of our Invention is to allow the ends of the flexible sides
to rest directly upon a recess made for them in the nut that screws on the shank,
instead of resting upon the sliding collar as previously described. In order to
prevent the sides from turning with the nut, when it is screwed up to expand the
net, we form flanges on the two sides which clasp both the shank and the wedge
shaped head.
When the sides.are nearly screwed up by the nut to their fully expanded position
pins on the wedge shaped head take into slots made for them in the flanges of the
sides and securely lock them fast.
In lieu of having recessed faces for the sides the wedge shaped head may be made
with inclined slots passing through it in the direction of the shank. The ends of the
sides are pushed through these slots and rest upon a nut or collar working on the
screw of the shank. The slots in the head are made wider than the thickness of
the sides to allow them to expand horizontally, but are of the same depth, so that
the sides are firmly held in them in a vertical direction.

COMPLETE SPECIFICATION.
Improvements in Landing Nets.
We, ARTHUR THOMAS ALLCOCK, Engineer, and DAVID SLATER, Fishing tackle
maker, both of Newark upon Trent, in the County of Nottingham, do hereby declare
the nature of our said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
Our invention has for its object Improvements in what are known as "Collapsing
rings for landing nets," and refers particularly to the method of securing the sides of
such rings to the handle, so that they may be taken apart for convenience of carriage,
when not in use.
In the accompanying sheet of drawings Figures 1 and 2 illustrate one part of our
invention.
We form beyond the screw S, which serves to attach the net to the handle H, a
square or polygonal shank A terminating in a projecting head B, which is made
with two inclined recesses and forming an inverted wedge.
Upon the square shank A is a sliding collar C. having a pocket or recess c and c¹
on either side corresponding to the recessed faces band on the head B.
A nut D, on the screw S can traverse the collar Cup the shank A. The two
sides E and E¹ of the ring are formed of flexible material, such as wood, whale
bone or steel, and they may be either jointed together in the centre, as shown in
dotted lines at F to form a balloon shaped ring, or have their outer ends fastened
together with a cord or wire G to form a triangular shaped ring, in any of the usual
methods.
The inner ends of the sides E and E' fit and drop into the pockets or recesses c and.c¹
formed for them on the sliding collar C and are further held up by the recessed
faces and of the wedge shaped head B.
Upon screwing up the nut D, the sliding collar C is forced towards the head B, and
the sides E and E¹ of the ring sliding up the inclined faces 6 and 6 of the head B
are expanded and pressed outwards, until the whole forms one rigid frame.
When, as shown in Figure 2, the nut D is unscrewed the collar C and sides E
and E' slide down away from the head B, and the whole arrangement collapses.
The sides E and E¹ can then be withdrawn from the head B and collar Cand
folded up with the net for packing away.
In a modification of this arrangement shown in fig. 3 the collar C with its two
pockets or recesses c and d may be made fast to the shank A, and the wedge
shaped head B made to slide towards it. The screw S₁ and the nut D. in this
case being on the outer side of the shank A from the handle H.
For large and heavy rings for nets we use the arrangement shown in Fig. 4. To
the shank A. we joint the two arins B and B, which are made with recesses b and b¹
at their outer ends, so that they may turn in a horizontal direction parallel with the
sides E and E¹ of the ring. Stops e and e¹ are formed on the sides E and E¹ of the
ring, against which the jointed arins B and B¹ bear, so forming a toggle joint, which
upon the nut D being screwed up expands the sides E and E¹ of the ring in a powerful
manner, and avoids friction as the sides E and E¹ have not to slide in the recesses b
and b¹.
Another modification of our invention shown in Fig. 5. is to allow the ends of the
sides E and E¹ to rest directly upon a recess made for them in the nut D. of the
screw S, instead of resting upon the sliding collar previously described. In order to
prevent the sides E and E from turning with the nut. D. When it is screwed
up to expand the ring, we form flanges of and f¹ on the two sides, Ezand E¹ which

page_text: clasp both the shank A and the wedge shaped head. When the sides E and E¹
are nearly screwed up by the nut D to their fully expanded position, projecting
pins p and p take into slots made for them in the flanges f. and f¹ of the sides
E and E and securely lock them fast.
In Figure 6. in lieu of the wedge shaped head B having recessed faces for the
sides E and E it is made with inclined slots 0 and 0₁ passing through it in the
direction of the shank and handle H. The ends of the sides E and E¹ pass through
these slots and rest upon a nut or collar D working on the screw S.--The slots O
and O are made wider than the thickness of the sides E and E to allow them to
expand horizontally, but are of the same depth so that the sides are firmly held in them
in a vertical direction.-On the nut or collar D being screwed up the sides E and E¹
are pushed up the inclined slots O and O' and expanded to form a rigid frame.
In some cases the nut D may be dispensed with, the ordinary nut in the handle H
being sufficient to move the sliding collar towards the wedge shaped head B.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. Expanding the rings of landing nets by causing the ends of their sides to slide
up over a wedge shaped head, as shown in Figures 1. 2. 3. 5 and 6.
2. Expanding the rings of Landing nets by means of the toggle joint as shown in
Fig. 4.
3. The combination of the wedge shaped head B and sliding collar C. for the
purposes set forth and described.
