Definitions

  • the honeycomb member comprises a center wall and a plurality of walls extending on both sides of the center wall to provide cell portions on both sides of the center wall, the surface of the center wall in each cell portion being formed with a depression of greater depth in the center than adjacent said plurality of walls, and said plurality of walls having a greater thickness adjacent the center wall than at their outer edges.
  • honeycombs made of wax or artificial material similar to wax have already been developed to avoid these disadvantages.
  • the wall height of these honeycombs is only partially made artificially so that the bees themselves build these partial walls to their full extent.
  • These honeycombs, which are intended only for the honey chamber have the disadvantage of being made of a material which, as in the case of natural honeycombs, is very fragile, so that attempts have also already been made to increase the firmness of such honeycombs by reinforcing or strengthening them with some other material.
  • these honeycombs are of only limited use in practice as the skins which are left behind when the bees hatch out gradually narrow the cell chamber so that eventually the honeycombs become useless and have to be replaced.
  • honeycombs made of sheet metal which are produced with a reduced wall extent, (somewhat more than half the full extent), so that the bees build the wall up to its full extent with their own wax.
  • a reduced wall extent (somewhat more than half the full extent)
  • honeycombs are unsuitable and that they have not been adopted.
  • One reason for this may have been that the production of such honeycombs is very complicated and extremely expensive, but the main reason is that the bees reject this material.
  • honeycombs in which, instead of there being a center wall with double-sided cells, there are cells provided only on one wall.
  • Such honeycombs can be produced from plastic, light metal, pressed material or similar.
  • Such honeycombs in which the full extent of the cell walls is made of artificial material are intended solely for making honey in, and can only be used as such.
  • Plastic honeycombs with full cell wall extent basically have the disadvantage that the skins left behind by the bees, when they hatch out, gradually narrow the cell chamber. The removal of these skins is extremely difficult, and in practice, cannot be carried out. Therefore, these honeycombs eventually become useless and have to be replaced. A further difficulty occurs in such honeycombs because the bees cannot dispose of their surplus wax.
  • Honeycombs made of plastic material with cells arranged on both sides of a center wall are provided in which the cell wall height is one-third to one-half of the full height of the cell wall in order to make the bees build up the honeycombs to the full height of the cell wall with their wax.
  • the honeycomb is molded from plastic material and the floor of the cell is provided with a depression, which increases radially inwardly.
  • This invention also provides a mold form for producing such honeycombs, in which the fixed mold part and also the movable mold part for each individual cell is provided with a separate mold head which operates independent of the other mold heads and is loosely mounted.
  • the fixed mold part comprises an ejection device which is connected to part of the mold heads on the fixed mold part.
  • a honeycomb member of synthetic plastic material for use in producing a honeycomb, which comprises a center wall and a plurality of walls extending on both sides of the center wall to provide cell portions on both sides of the center wall, the surface of the center wall in each cell portion being formed with a depression of greater depth in the center than adjacent said plurality of walls, and said plurality of walls having a greater thickness adjacent the center wall than at their outer edges.
  • the extent of the plurality of walls be reduced (preferably about one-third to onehalf of the full cell wall extent 12.5 mm), that the cells be injected of plastic, that the cell walls taper, and that the surface of the center wall for each cell portion have a depression increasing from the plurality of walls to the middle.
  • the depression in the cell is preferably arcuate, for example, shaped hemispherically. However, it can also be formed in such a way that, in crosssection, it is shaped like a channel, whereby the side walls are inclined at an angle of approximately 45. The angle should be between 30 and 60 and the floor is parallel to the center wall.
  • the bees send their feeding juice or their milk into the center of the depression if it has a deeper depression in the middle..Thus, the hatched maggots are able to find food in their immediate vicinity.
  • the plastic honeycomb which is provided with a reduced wall extent, according to this invention.
  • the skins and the cell walls consisting partly of plastic, partly of wax are heated to the extent that the wax melts and the skins are exposed.
  • the latter can then very easily be removed mechanically, e.g., by means of a brush, so that afterwards the original honeycomb can be used again to its full capacity.
  • the tapering form of the cell walls simplifies the removal of such skins and this is decisive for the use of the plastic honeycomb in the breeding chamber.
  • a mold for producing the honeycombs may consist of two detachable mold parts which are movable in relation to each other.
  • the two mold parts are constructed with the sides facing each other in such a way that they form the center wall with depressions and the cell walls of reduced extent.
  • the one mold part which is rigidly connected to the machine receives the elements which form the single cells, and preferably consists ofa row ofledges each of the width ofa cell. Bolts for displaced cells are inserted into bores in these ledges so that when a large number of ledges are placed in a row, the honeycomb structure of the mold part is obtained.
  • the bolts, which are inserted, are fixed to the ledges, and the head of the bolt, which determines the cell form, has a ring-shaped stop at the point of transition to its shaft, so that when the ledges are shifted these bolts are also shifted with them.
  • the mold elements which form a unit with the ledges or are otherwise directly connected with the ledges have ejection members which are used together to eject the ready molded product. In so doing, all the ejection members of the fixed mold part are moved together against the molded product and also together raise it from the fixed mold part.
  • the counter mold part is likewise constructed of single elements or bolts whose heads have a form which corresponds to the formof the cell.
  • the lateral walls of the cell-forming walls of the bolt heads are formed somewhat more tapered than on the fixed mold part, so that the molded product can be separated more easily from the movable mold part.
  • the individual elements or bolts are here screwed singlyonto the frame part of the movable mold part.
  • a considerable saving in weight of the honeycomb according to the invention can be achieved because the frame of the honeycomb itself is omitted with such plastic models and, instead of it, a spacing and suspension device may be used, which also preferably consists of plastic. Such a spacing device guarantees a constant distance from the next honeycomb, so that the path between two adjacent honeycombs is kept free for the bees.
  • the spacing device consists of two parts separated from each other, one part being prescribed for one side of the honeycomb and the other part for the other side of the honeycomb.
  • the suspension device preferably forms a unit with the spacing device; the former is likewise divided so that the combination of spacing device and suspension device consists of two symmetrical parts for each honeycomb, which are arranged on both sides of the honeycomb with each being symmetrical to the center wall.
  • This arrangement is selected so that there is the advantage that a member is prescribed for each side of the honeycomb which comprises, for example, projections which can be inserted into corresponding honeycomb cells for support.
  • the arrangement can also be selected so that these two members are screwed together through the honeycomb or connected with each other by means of rods or something similar.
  • the actual spacing elements are here formed in the shape of spacer members which extend from the honeycomb and operate in conjunction with corresponding spacer members belonging to the spacing device of the adjacent honeycomb. In this way there is the guarantee that the spacing device can easily be put together and also easily taken apart again.
  • the suspension device is molded as a projecting nose in the case of a special embodiment onto the corresponding members of the spacing device, whereby the nose projects from side edges of the honeycomb so that the suspension of the honeycomb on projections in the hive provided for that purpose is guaranteed.
  • Both of the parts of the suspension device which are provided for one honeycomb, one on each face thereof, are connected with each other when in use, whereby the two parts of the suspension device are prevented from moving away from each other.
  • FIG. 1 is a cross-section of a part of a honeycomb

  • a plurality of cell walls 2, 2 are formed which taper away from the center wall 1.
  • the inner surfaces 3 of walls 2, 2' are preferably formed hexagonally, but they can also have a circular cross-section.
  • center wall 1 are, in a hexagonal arrangement of the cells, provided with a depression, whereby there are preferably provided planar center parts 4 and inclined surfaces 5, which run from the center part 4 to the point where they are met by side wall surfaces 3. These surfaces are inclined at an angle between 30 and 60, preferably about 45 to the center parts 4.
  • the surfaces 4' of the center wall are formed hemispherically, whereby the cells themselves can either be circular or hexagonal.
  • Decisive for the form of the surfaces of center wall 1' is the fact that the surfaces each contain a relatively deep depression in which the bees deposit the feeding juice so that there is the guarantee that the young maggots are certain to find their food.
  • FIG. 3 there is shown a iew of the arrangement of the cells according to FIG. 1, whereby the cell form is hexagonal.
  • the exterior limit 6 ofthe molded synthetic plastic honeycomb is, as the honeycomb is rigid in itself, made without a frame. Three sides ofthe exterior side beneath, can be formed here so that the incomplete cells are open outwards, whereas the upper side 7 is, for practical purposes, formed so that the incomplete cells, as shown at 8, are sealed at the end of the molding process. However, it is also possible to keep the incomplete cells of the side 7 of the honeycomb open.
  • a spacing and suspension device is shown as a whole at 9 in FIGS. 4 and 5 and consists of members 10, 11, 14 and 12, 13, 15.

  • the spacing and suspension device is shown on reduced scale.
  • This arrangement shows one of the narrow sides of the honeycomb.
  • the members 10 and 11 are formed for example as plastic ledges which are connected with spacer fingers 16 and 17 which are resilient and cooperate with corresponding opposite members 18 and 19 on the next honeycomb.
  • One member 11, corresponding to the member 10 comprises corresponding spacer fingers 18 and 19.
  • projections 20 are formed which snugly fit within a cell and which are arranged at such a distance from each other that they correspond to a multiple of the distance between honeycomb cells.
  • the members 10 and 11 can be inserted into the cells and 6 jections can in addition comprise further arrangements of some kind which guarantee a hold in the cells. e.g., a connection with the floor of the cell which is represented by the center wall 21.
  • the members 10, 11 include extensions l4, 15 for example at their upper ends and preferably running flush with the upper edge. These extensions 14, 15, extend from the side edge of the honeycomb. Thus noses are formed on which the honeycomb can be hung up on the interior of the hive.
  • a device 22 can be provided which connects the two adjacent projections 14 and 15 with each other.
  • the device 22 is likewise preferably a plastic member. which can snap into place by means of projections in recesses on the upper side of the projections 14 and 15. Alternatively, a tongue and groove joint or some other known type of fixture can be selected.
  • FIGS. 6 and 7 there is shown a simplified embodiment of a spacing and suspension device 23.
  • the members 24 and 25 are here connected to each other by means of screw connections 26 and hold the honeycomb 27 between them.
  • handles 28 are provided in this embodiment which are intended to simplify insertion into a hive. Otherwise the structure of this spacing and suspension device 23 is similar to the one described in connection with FIGS. 4 and 5.
  • FIG. 8 in diagram and in cross-section, the mold for injection-molding the plastic honeycomb according to the invention is shown.
  • This mold consists of a mold part 30 firmly fixed to the machine and a mold part 31 which is movably connected with the machine and which can be removed.
  • the mold part 30, which is firmly fixed to the machine part consists of a framelike formation 32, on which mold heads 33, aligned with each other and arranged at a distance from one another, are provided (FIG. 9); furthermore, the fixed mold part 30 comprises bores 34 and an ejection device 35 to which the ejection members 36 for the mold heads 33 are mounted by means of screw connections.
  • shafts 38 carrying mold heads 39 aligned with each other and arranged in the manner shown in FIG. 9.
  • the shafts 38 are fixed to the part 32 by means of screw connections 40.
  • the movable mold part 31 similarly comprises a frame part 41 formed with bores 42. In these bores, shafts 43 are received by bolts 44 which, at their front end have mold heads 45 for forming the cells of the plastic honeycomb.
  • the shafts 43 with the bolts 44 are fixed to the mold part by means of screw connections.
  • the taper of the side walls 47, 48 of the mold heads 45 is made somewhat greater than the taper of the side walls 49 and 50 of the mold heads 39, so that a removal of the molded product 51 from the mold is simplified.
