Definitions

  • the purpose of this invention is to provide environment friendly moulded weights for angling and to give an account of the process of manufacturing such weights.
  • Weights of various kind have since long been used within the field of angling. There has been a wide range of uses. The material that has dominated the weight-market during modern times is lead.
  • the reasons for making weights out of led have principally been the high density of lead, the uncomplicated process of production, and its relative inexpensiveness.
  • the increase in knowledge has given rise to a great number of new angling methods, amongst others the so called artificial fly-spinning and also various kinds of bottom-angling with natural baits, this development having caused a drastical increase in the demand for lead-weights.
  • US-A-3 834 059 bears reference to a weight made of watersoluble concrete, which dissolves as it is lowered into the water.
  • Bottom-angling is carried out by way of permanently attaching a weight to the end of the angling-line so that it becomes possible to throw the weight relatively far out into the water together with hooks attached to the angling-line by the weight, baited with natural baits or artificial baits such as flies or special lures.
  • the purpose of bottom-angling is to reach the bottom, as a multitude of different species of fish are disposed to both live and search for food there, using the whole of the tackle, including the weight and baits.
  • Bottom-angling is usually pursued in still waters such as lakes and seas, and is a very common fishing method all over the world.
  • bottom-angling It is a prerequisite for bottom-angling that the weight is durable and does not dissolve in contact with water since the whole of the tackle, due to the floating capacity of the angling-line and some baits, would float to the surface without its weight. The purpose of bottom-angling would then be lost.
  • a factor that can prove troublesome in bottom- angling is that the angler rather often has his weight or bait stuck in the uneven bottomstructure. This being so , the angler is all too often compelled to pull off the angling-line, which not seldom means that the whole of the tackle, including weight and baits, is left on the bottom, hereby causing the previously mentioned environmental pollution which in part is composed of remaining lead.
  • the weight should be of a fair size.
  • a large weight made out of the material known to the context signifies that the weight will be too heavy for use. Therefore there is a demand for a comparatively large weight, with a not too high density, which is made of an entirely environment friendly material.
  • Artificial fly-spinning can very easily be campared to bottom-angling, the difference being that artificial fly-spinning most often is prosecuted in streaming waters.
  • the tempered concrete used for angling-weights according to the invention is based on sand, gravel, water, limestone, harmless minerals and, when needed, plaster.
  • Tempered concrete is in this context an unexploited material with the optimal qualities for functioning as an angling-weight. Since tempered concrete can be manufactured from nature ' s own harmless matter, the material in no way harms nature neither in the short nor long term. Moreover, tempered concrete is very easily moulded, inexpensive and also very hard and durable, which constitutes a material that works very well as angling-weights.
  • tempered concrete as material for making angling-weights
  • the fact is emphasized that it lies in the nature of tempered concrete to allow for great variety when it comes to the weight in relation to the size of the weights.
  • the tempered concrete is suitable for the making of both large, light weights and large, heavy weights, et cetera. This constitutes a multitude of new possibilities as regards the use of these weights within angling.
  • An important factor in the making of concrete weights to be used in bottom-angling and artificial fly-spinning is. as previously indicated, that the tempered concrete in use must be hard and strong and must by no means dissolve in contact with water during fishing.
  • the tempered concrete must therefore burn, or temper as we usually designate the process, before the weight can be considered ready for use. Tempering is best carried out in two steps: The first step being that the weight is left to temper in its mould for some time. For how long depends on which mixture of concrete that has been used. A recommended time-span could be 24 hours. This first step of the tempering-process is a prerequisite of allowing for the weight to be lifted out of its mould. The second step consists of the concrete weight being stored for three to seven days after the actual production process, so as to obtain a high degree of hardness and strength. This should take place in humid conditions. Under humid conditions, tempered concrete obtains the greater portion of its hardness the first seven days after the actual production process and continues to temper even a while thereafter.
  • Figure 1 shows an example of an angling weight in accordance with the invention.
  • the main body of the weight is marked a, while b shows a reinforcement-wire and c indicates the loop that is formed by the reinforcement-wire outside the very weight and that is to be attached to the angling-line.
  • Figure 2 displays a double mould for casting two angling-weights in accordance with the invention.
  • the bodies of the mould are marked a, the hinges between the bodies are marked b and the moulds themselves are indicated by a c.
  • Figure 3 shows a variant of the mould in figure 2. Apart from the terms already provided by figure 2, the d indicates the loop by which the completed weight is to be attached to the angling-line.
  • Figures 4 and 5 show examples of different ways of designing the angling-weight in accordance with the invention.
  • the weights shown are of low density, while 5b and 5d depict weights with high density.
  • Figures 6 and 7 demonstrate various ways of reinforcing the angling- weight in accordance with the invention.
  • Figure 8 indicates how large the replenishment-opening (a) of the mould should be in proportion to the diameter of the weight.
  • the main body of the weight is moulded from tempered concrete.
  • a wire is best used (Fig. 1 .b,c) made of steel, iron, copper or any other bendable material.
  • the thread protrudes from the moulded body partly to function as a line-attachment (Fig. I .e.) and partly as reinforcement for the weight (Fig. 1 .b.).
  • the shape of the weight (Fig.4.) and the density of the tempered concrete can be varied. For instance, small and relatively light weights (Fig. 5. a.) can be moulded, as well as small and relatively heavy weights (Fig.
  • the tempered concrete can, for instance, contain sand, water, limestone, harmless minerals and, when needed, plaster and pebbles or gravel.
  • What type of metal or what material is used in the wire dependens on what kind of weight is intended.
  • a large weight of high density may need a wire of an extra thick and thus extra heavy material.
  • a small weight of low density may need a wire of an extra thin and thus extra light material, wherefore the choise of material for the wire is left open.
  • the weight can, as an example, be cast in a two-piece mould (Fig. 2. and 3.) out of material suitable for a particular tempered concrete- mixture, such as metal, plastic, wood, plaster, cheramics, silicon or an other material.
  • the mould can be composed of two parts (Fig. 2. a. and 3. a.) which are smeared with a suitable lubricant, e.g. vegetable oil, and are held together by, for instance, hinges (Fig. 2.b. and 3.b.) .
  • the shape of the weight is thereby determined by the shapes of the two cavities in each half of the mould (Fig. 2.c. and 3.c).
  • the wire that is to function as the reinforcement and as the attachment for the angling-line is placed in grooves on one half of the mould (Fig. 3. a.). These grooves also function as funnel/replenishment-openings for the mould. In this manner the wire protrudes from the main body as reinforcement (Fig. 3. c.) to form an attachment for the angling-line outside the mould (Fig. 3. d.).
  • moulds can also be used. People in general may, when making a smaller number of weights, well use disposable moulds of tempered clay or cheramics (to be used once or twice). Under the assumption that the moulds are thoroughly smeared with a suitable lubricant, i.e. vegetable oil, it works spectacularly to cast weights in an open mould consisting, for instance, of a mould-body with open hollows corresponding to the intended size of the weights. The hallows are then filled with the appropriate concrete-mixture in which a reinforcement-wire with a loop is attached.
  • a suitable lubricant i.e. vegetable oil
  • Example 1 A weight weighing 60 grams +/- 2 grams cast of concrete-alloy with a density of 2 500 kg/m3 can, for instance, depending on the shape, obtain the measurements 12,5 x 12,5 x 80,0 mm (Width x depth x height).
  • the optimal concrete-alloy as used for cast angling-weights should contain relatively small pebbles/fine gravel and should be mixed a relatively large quantity of water to begin with, this is then pressed out from the mould together with air during the moulding process.
  • the optimal mixture could, disregarding its density, be compared to what is known in the concrete business as semi fine-concrete and fine-concrete.
  • a tempered concrete mixture was made and moulded as is described in example 1.
  • the result being a concrete weight with the expected density of 3 500 kg/m3.
  • the strength proved to be excellent.
  • a tempered concrete mixture was made and moulded as described in example 1. The result being a concrete weight with the expected density of 4 500 kg/m3. The strength proved to be excellent.
  • the wire can be moulded into the main body in various ways (Fig. 6.). This mainly depending on what requirements are set for the strength of the fastening of the wire.
  • the experiments stated below show examples of various ways to fasten the wire and how strong these fastenings are:
  • the wire was moulded straight into (Fig. 6. a.) three main bodies with different densities in accordance with examples 1 to 3.
  • the strength proved to be insufficient for the weight with density of 2 500 kg/m3 in accordance with example 1, but excellent for the weights with the densities 3 500 kg/m3 and 4 500 kg/m3 in accordance with example 2 and 3.
  • Example 7 In this experiment the wire was moulded in the shape of an elliptical ring
