  • the securing means are lugs which push engage into slots.
  • the lugs may be bifurcated and such as to be resiliently compressed on entering the slots and resiliently spring back when reaching the end of the slots.
  • the fan cowl and/or the channel-shaped members are made of plastics material and the securing means integrally formed therewith.

  • the arrangement of the invention is particularly suited for fitment to a range of radiator sizes, since it is only necessary to provide channel members where the push-engagement parts are spaced from the bottom of the channel members by varying depths, so that whatever radiator size the channel members are fitted over, the push-engagement parts lie at the same spacing from each other, corresponding to the corresponding parts on the cowl, which can therefore be common to the range of radiators.

  • the cowl assembly for the fan (not shown) consists of a cowl 7 of plastics material and channel members 8, 9, also of plastics material.

Description

  • This invention relates to a cowl assembly for a fan of an automobile radiator.
  • Hitherto, such cowls have been secured to radiators by means of bolts passing through the cowls, which bolts screw into nuts welded to the radiator casing. Alternatively, if the radiators had header tanks of plastics material, the header tanks carried special mouldings which could be attached to the cowls.
  • This invention provides a cowl assembly for a fan of an automobile radiator, the assembly comprising a fan cowl; a pair of channel-shaped members for fitting over opposite ends of the radiator; and securing means on the fan cowl and on each channel-shaped member such that the fan cowl can be secured by push-engagement to the channel-shaped members whereby when the channel-shaped members are fitted onto the opposite ends of the radiator the fan cowl can be secured thereto and thus mounted on the radiator.
  • The arrangement of this invention eliminates the need for nuts to be welded to the radiator, or for plastics header tanks to have special mouldings.
  • Advantageously the securing means are lugs which push engage into slots. The lugs may be bifurcated and such as to be resiliently compressed on entering the slots and resiliently spring back when reaching the end of the slots.
  • Advantageously the fan cowl and/or the channel-shaped members are made of plastics material and the securing means integrally formed therewith.
  • The cowl may be provided with an additional set of securing means arranged on an axis at right angles to the first set, and spaced apart by a different amount to these. With this arrangement the same cowl and same channel-shaped members can be used on radiators of different height, the first set of securing means being appropriate for one radiator height and the differently spaced set being appropriate for a radiator of a different height.
  • In any case, the arrangement of the invention is particularly suited for fitment to a range of radiator sizes, since it is only necessary to provide channel members where the push-engagement parts are spaced from the bottom of the channel members by varying depths, so that whatever radiator size the channel members are fitted over, the push-engagement parts lie at the same spacing from each other, corresponding to the corresponding parts on the cowl, which can therefore be common to the range of radiators.
  • A cowl assembly for an automobile radiator fan, constructed in accordance with the invention, will now be described by way of example with reference to the accompanying drawing, which is a perspective view of the cowl assembly on the radiator.
  • The radiator forms part of the engine cooling system in the usual way, and comprises header tank 1, 2, tubes 3 extending between them, and corrugated finning 4 packed between the tubes. The sides of the radiator are defined by channel shaped side pieces 5, 6.
  • The cowl assembly for the fan (not shown) consists of a cowl 7 of plastics material and channel members 8, 9, also of plastics material. The channel members 8, 9, are shaped to fit closely over the channel shaped side pieces 5, of the radiator. The channel members 8, 9 are integrally formed each with a pair of bifurcated lugs 10, 11. The cowl has slots 12, 13 to receive the bifurcated lugs.
  • The lugs 10, 11 and the slots 12, 13 are so located and dimensioned that, when the channel members 8, 9 have been fitted over the side pieces 5, 6 of the radiator, the vertical spacing between them (as seen in the drawing), corresponds exactly to the vertical spacing of the slots 12 and 13 in the cowl. Consequently, the cowl can simply be pushed so that the slots pass over the lugs in order to attach it to the radiator.
  • As each lug enters its associated slot, the two parts of the lug are pushed towards each other, and then spring back when the ends of the lug have reached the other end of the slot. The channel members are now secured to the cowl, and the cowl is consequently secured to the radiator. Sideways movement of the channel members along the side pieces of the radiator is impossible due to friction between the parts.
  • The cowl has a second set of slots 14, 15 arranged on a horizontal axis as seen in the drawing, and these lugs are faced apart by about two inches more than the slots 12, 13, the purpose of this is so that the same cowl can be used with the same channel members on another radiator which, in its vertical height, is about two inches bigger than the one illustrated in the drawing.
  • It will be apparent that the method of attachment of the cowl to the radiator is in any case easily adaptable to radiators of different sizes, in that the cowl can remain the same but the channel members 8, 9 need only have a different depths between the position of the lugs 10, 11 and the base of the channel members.
  • If desired, as an additional precaution for preventing movement of the channel members 8, 9 along the side pieces 5, 6 the side pieces could be formed with studs which engage the channel members, or the channel members could be provided with projections which engage the fins 3.
  • If desired, the slots 12, 13 could be provided on the channel members 8, 9 and the lugs 10, 11 could be provided on the cowl. Also, the channel members 8, 9 could be shaped for fitting over the header tanks 1, 2 instead of over the side pieces 5, 6.
