7 Claims. (Cl. 87-12) `V'My invention resides in the field of nets, such as the nets used in fishing and trapping, tennis, badminton, volley ball and other outdoor games. The knots used in these kinds of nets vary quite widely depending upon the type of use to be made of the net, the material from which the strands of the net are made, the conditions under which the net will be used, the strength necessary in the net necessitated by its application, and vother factors. Various knots found suitable for one type of use are totally inappropriate in other fields in that they fail to stand up to the ,requirements of that particular activity.

- Possibly the most important factor in nets involving their over-all utility, other than the material from which the strands of the netV are made, is the knots used, in that ineffective or inappropriate knots can render the net inefficient if not useless and possibly dangerous.

With the advent of new and improved mal--l terials that can be used lin the strands of the net, the conventional knots are on occasion .inappropriate in that efiiciency of a knot is ofttimes directly predicated upon the particular material being'used.

Therefore, the primary object of my invention is a new and improved knot to be used in nets of all types and description wherein the knot is economical from the standpoint of the cost of the machinery necessary to .produce the same.

A further object of my invention is a new and improved knot to be used to secure two strands of lines or twine together so as to acquire a firm and tight connection between the two, regardless of whether the lineis'made of conventional material, such as cotton or linen or, one of the'- new materials, such as nylon.

Other objects will appear from timev to time` in the ensuing specification 'and drawings, in

which:

Figure l is a plan view of a section of a net employing my new knot; and v Figure 2 is a detail view of my new knot showing one ofthese knots in an expanded or loosened condition.

In Figure l, a section of net N is shown as composed of a plurality of strands vertically disposed, such as denoted by reference numerals l0, [2, |4, |0, l8 and 20. These strands are woven into a net, -by conventional net-making machines, so as to .be knotted together at equally spaced intervals, such as by a knot K, so that a regular symmetric pattern is formed from the strands to produce an even well-balanced net. Any one of a large number of knots can be used to connect the various strands together, and I have invented a knotfor thispurpose which is far more efficient than conventional knots in extensive use at the present time.

, One of my new knots is shown in Figure 2, and represents the connection of strands |8 and 20. Strand 20 has been formed into a loopil which is acquired by laying one of its legs a over the other leg b which reverses upon itself so that the legs a and b leading away from the loop Z in the same manner that they would have been if the loop had not been formed. By over-looping the legs, the loop is provided with unintertwined sub-loop s.

Strand l8 is formed in a loop t whichhas a' strap portion r residing between the legs a and b of the strand 20. Leading away from the strap portion r` area pair of legs c and d, the leg d extending up through the sub-loop s in strand 20, as shown in Figure 2. The legs c and d cross to form a loop t in the strand, the cross occurring that the legs a and b of strand 20 approach the loop t .in strand 18 from opposite sides and cross one :another while passing through said loop. The leg a of strand IB which lies on top of thef leg bA which first crosses outside of the loop t; must also lie on top of the leg b at the second;v

crossing within loop t.

While I have described other cross, a leg leading away to the upper left,

and such, it should be understood that these` terms are purely relative and are variable depending upon how the knot is orientated and they have been only for purposes of description and illustration in Figure 2. V

I have found that this particular type of knot is extremely effective when used in combination with 'threads or strands of nylon. When nylon' was first used in nets of various types, it proved,

not satisfactory' in that the knots conventionally used with'other materials would not hold nylon,

' and for several years, the production of nets of nylon was hindered due to the fact that the 2knots used would not form a sufficiently tight connection.

The explanation for this can probthe legs, strand and loop'by relative terms, such as, one leg residing' o n top ofthe other, one cross being above the ably be derlved from the inherent characteristics of nylon material when formed in the threads of nets, but for purposes of my invention, the explanation of the slipping phenomena of nylon is unimportant.

When I state that this new and improved knot is particularly efiicient when used with nylon, I do not wish to be restricted to this particular material in that my new and improved knot has proven to be extrernely efiicient when used with materials that have been employed in net-making for years, such as linen, cotton and the like.

While I have illustrated and described one form of my invention, it should be understood that I do not wish to be restricted to the particular embodiment shown and described in that my invention is susoeptible of numerous changes and modifications without departing from its essentialtheme, and the hereinabove description and disclosure should be interpreted as only illustrative or diagrammatic of my invention eSSential characteristics and should not be interpreted to re- Strict the Same except as by the appended claims.
