Definitions

  • ABSTRACT Anegg incubating tray having egg cells arranged in a diagonal manner so, that 48 cellsare located CARRIER United States Patent [191 Levin [541 not; INCUBATING TRAY WITH RACK AND on each tray. Each cell is surrounded by six upwardly disposed,
  • the rack on which the carrier is placed consists of a metal rack having an end which is shaped to accomodate the carrier of this invention and includes the normal end members bent over so that they do not interfere with the present carrier and the addition of an L-shaped extending member so as to properly hold the carrier in position.
  • This invention relates to egg incubating and particularly to an egg incubating tray, the carrier on which a group of them are positioned and the rack on which the carrier is placed in the incubator.
  • the projections because of the layout of the egg cells, form a square-like pattern. This does not conform to the general round shape of the egg, and can presentproblems during incubation. Moreimportantly, the horizontally disposedprojections surrounding each egg, that is, projections 45 in Thelig, are concavely rounded. This provides two rather sharp points at each end of the projection. These points will dig in and .canbreak the eggs.
  • the concavity must be exactly the same shape as the curvature of the egg for these projections towork, and since in the usual case, the egg will be slightly different in shape than the concavity, the two points will act as spears andtend to rupture the egg.
  • the carrier for the tray shouldprovide for the proper circulation of gases through and around the egg trays and the racks'on which the egg trays are posi tioned in the incubator should be constructed in such a manner that it can accomodate the present size egg trays.
  • a carrier is also provided to hold three interfitting trays.
  • the carrier is constructed to provide the maximum gas circulation.
  • the carrier then fits on a rack which consists of a novel construction whereby a conventional rack has the end members bent away and an extension added on so that the carrier will fit completely on the rack.
  • the object of this invention is then to provide incubation egg trays having a maximum amount of egg cells for a set size, that is 48 egg cells instead of 36. It is a further object to provide an incubating egg tray having shock absorbing means for holding and cradeling the eggs so that there is the least possible amount of breakage.
  • a still further object of the invention is to provide a novel carrier which permits the maximum circulation of gases around three interfitting egg trays.
  • A'still further object of the invention is to provide a rack by altering a conventional rack to accomodate the carrier.
  • FIG. 1 illustrates a prospective view of an egg tray.
  • FIG. 2 illustrates a top plan view of an egg tray.
  • FIG. 3 illustrates a bottom plan view of an egg tray.
  • FIG. 3a illustrates a single egg cell.
  • FIG. 4 illustrates a stacking arrangement of the egg trays.
  • FIG. 7 illustrates a carrier and rack and shows their interfitting arrangement.
  • an egg tray is provided with substantially increased egg holding capacity.
  • the structure inclues eight rows of cells. Each row is offset by half the width of an egg cell from the cells in the adjacent row. In other words, taking the row shown on the extreme left in FIG. 2, the cells in that row are offset by half the width of a cell from those in the row immediately to its right. The same pattern exists in all eightrows of the cells. This permits cells to be provided without one egg contacting another.
  • the eggs will be positioned as shown in FIG. 6 so that the greater circumference on one egg will not interfere with the greater circumference of the egg adjacent to it in the next row. For example, as shown by the dotted lines in FIG.
  • each of the 48 egg cells has six verticalprojections surrounding it. Four of these projections 4, are positioned at an angle of about 30 and are isoceles triangles in shape and tapered so that the base 6 is much thicker than the tip 7 to provide for flexibility thereby providing shock absorbing'qualities. When an egg is placed into a cell these projections have to flex so as not to injure the egg. The same shock absorption has to take place if a tray is moved during incubation.
  • the tips of the'projections are also rounded to avoid sharp points.
  • the tray itself is moulded or otherwise formed out of plastic or other strong material so that it comprises one integral section of material.
  • Struts 18 are positioned sothat they define the rows of egg cells.
  • Ribs 20 are then positioned between egg cells in the same row to interconnect struts 18. It will be noted that as shown by FIG. 3, rectangular open areas are formed by these struts and ribs. These areas correspond with the egg cells and thereby provide for free flow of gases throughout the incubation chamber.
  • each of these supports is a small recess 56 and also a short strut adjacent to the opening 58 to reinforce the areas surrounding the supports.
  • the supports are provided so that, as shown in FIG. '4, the egg comprised of two short members 26 and 27 which are at about an angle of 30 with respect to struts 18 and a straight strut parallel to 18, 28. This latter strut 28 has a reinforcing section 30 to strengthen it.
  • These struts form a jagged structure so that one tray can interfit with the next as shown in FIG. 5, and as will be described in more detail hereinafter.
  • Projections 4 are positioned on struts l8, and projections 12 are positioned in the cantilevered manner aforementioned, on struts l5 and 16.
  • each egg cell contains four horizontal projections. These consist of projections 32 which extend from ribs 20 and projecthe rib 20 between the first and second cells in the trays can be stacked on each other. When they are thus stacked, the tips 54 fit into the recesses 56 so as to provide for a secure stacking arrangement. It will be appreciated that the length of supports 52 is such'that they are longer than the maximum length of the eggs, as shown by dotted lines 53 so that they do not permit the eggs in one tray to contact and possibly rupture the" eggs in the next tray.
  • the two jagged edges 29 and 31 of the egg tray are designed so that the one egg tray can interfit with the next to form a continuous egg tray. This is especially important for conserving space.
  • the egg cells in one tray, tray 60, the lower tray in FIG. 5 interfit with the cells in 61 so that the same diagonal pattern of cells is continuous between egg trays.
  • the vertical projections 4 and 5 at the edges of each tray do not actually support the eggs in the adjacent trays, they do contact each other to provide increased support and strength to the tray and also so that the least amount of space is used.
  • struts 27 contact each other and struts 28 form almost a substantially straight line between the two trays. This also strangthens the trays and also leads to a substantial reduction in space. In fact, the construction is such that there is almost no lost space.
  • Carrier 62 comprises a rectangular frame 64 preferably made of metal or other strong material;
  • frame consists of two longitudinal L-shaped members 66 and 68 which interconnect by means of two short L-shaped members 69 and 70 to form a rectangular configuration.
  • Two short flat bracing members 72 are positioned between the horizontal sections of members 66 and 68 to further hold them together. These members curve slightly upwardly at their ends 74 to overlap the horizontal sections of channels 66 and 68.
  • These members are eight in number, six of them (76) being positioned proximate the center of the carrier and two 78 and 80 being positioned proximate members 66 and 68. This will leave the entire bottom of the carrier substantially open so that there can be a free flow of gases around the egg trays during incubation.
  • a handle 82 which is substantially rectangular in shape and being slightly bent outwardly to provide for easy grasping. It includes an L-shaped section 84 which is attached to the tray, a vertical member 86 extending therefrom and a C-shaped grasping section 88 connected to a vertical member 86. The other side of the handle includes an L-shaped member 89 connected to member 89 and also to grasping section 88 and including a section of metal 92 connected thereto.
  • projections 12 are positioned in a cantilever manner so that, as shown in FIG. 6, the tray or especially straight edges 45 and 47 of the tray will contact the inner surfaces 65 and 67 of the carrier. Cantilever projections 12 will then extend so that they rest on top edge 63and e 61- of members 66 and 68 and do 'not take up space in the inside of the carrier itself. This conserves the available space so that the maximum amount of egg cells can be provided in the trays.
  • the carrier will then fit into a rack 94 also shown in FIG. 7.
  • Rack 94 includes two L-shaped longitudinal members 96 and 98 and a single L-shaped bracing member 100 which interconnect the two members 96 and 98 at one end thereof.
  • This member 100 includes two extending sections 102 and 104 to which members 96 and 98 are connected by welding or other suitable fastening means.
  • the other end of the rack includes a horizontally disposed flat member 108 which connects the horizontal parts of members 96 and 98 together and is fastened thereto by welding or other suitable fastening means.
  • Two upright members 110 and 111 are fastened to the outside of members 96 and 98. These upright members are planer and each has a projecting triangular tab 112 and 113 with a bolt 114 and 115 respectively extending therefrom.
  • the vertically extending portion 120 of member 116 extends outwardly beyond the outer edge 109 of section 108. Vertical section 120 then projects upwardly at a distance from the outer edge 109 of section 108.
  • the conventional racks have sections 112 and 113 bent inwardly and do not have member 116 and therefore cannot accomodate the carrier and trays shown herein.
  • the rack shown herein solves this problem. i
  • An egg tray comprising a plurality of parallel struts a plurality of ribs interconnecting said struts to define a plurality of parallel rows of egg cells, said ribs being positioned between said struts to longitudinally offset the cells in one row by half the distance between the ribs from the egg cells in the proximate row six tapered vertically disposed projections mounted around said egg cells on said struts and said ribs to aid in supporting an egg and act as a shock absorber for the egg, and
  • the egg tray of claim 1 wherein there are eight parallel rows of egg cells with six cells in each row.
  • the egg tray of claim 4 including four vertically disposed cylindrical supports two of which are mounted in two rows proximate the: two rows which are positioned on the rows proximate rows in the center of the tray, said supports are tapered and disposed along the straight edges of said tray.
  • leading edges being disposed the same radial disdisposed parallel to said londitudinal members and connecting said laterally disposed members so that the rectangular area is unobstructed to permit the free flow of gas around said trays during incubation of eggs therein.
  • a rack for a carrier which is adapted to hold egg trays comprising two longitudinally disposed L-shaped support members having first and second ends a laterally disposed end member interconnecting first ends of said longitudinally disposed members a laterally disposed flat support member interconnecting said second ends of said longitudinally disposed members, and
  • an L-shaped stop member having two flat perpendicular sections, a first section connected to said laterally disposed flat support member and a second section extending upwardly therefrom and away from said laterally disposed flat member.
  • the rack of claim 11 including two upright members fastened to the second ends of the two longitudinally disposed L-shaped support members, each of said upright members having a projecting tab which is perpendicular to the member, each of said tabs extending away from the other.
