  • Disc/cam type tipping mechanism for bucket conveyor
    Patent number: 5105933
    Abstract: A tipping mechanism for buckets carried by a conveyor or elevator. Each bucket 28 is attached to a chain 26 by a swing link 29 and each bucket carries a sector shape cam 30. As the buckets are carried around a sprocket 27 the cam 30 contacts a peg 31, so as to cause the bucket to progressively tip and empty. The movement of the buckets back to their horizontal position is fully controlled and is smooth by virtue of the contact between a French curve on the cam 30 and a cam surface 35 of substantially wedge shape located above or below the conveyor or elevator chain.

  • Method and apparatus for securing card-clothing to flats
    Patent number: 5095585
    Abstract: A method and apparatus for securing card-clothed tops to the flats of revolving flat-type carding machines is disclosed, which obviates the necessity for specialist machines used for securing clipped tops to the flanges of the flats. A special type of top clip is provided which, besides being preformed to engage with the bottom side of the top as is usual, also has an inward hooked formation along its upper longitudinal edge. In addition, various kinds of tensioning elements are provided, each of which is engagable with the hooked formations on the clips, and is resiliently loaded, so that in the assembled condition, it causes the clips to pull the top tightly into engagement with the flanges of the flat.

  • Production of shaped filamentary structures
    Patent number: 5081754
    Abstract: A method of producing a shaped fibrous fabric structure is similar to that described in the parent application, in that a continuous filament sheet is subjected to a needle punching action, segments are cut from the sheet and these segments are assembled to form an annulus, and then subjected to rotary motion under a reciprocating needling head and continuing to add segments to build up a stack of layers while at the same time continuing the needling action, and lowering the base of the stack relatively to the needling head. However, in a final step, one or more layers of segments are added to the top of the stack, and these are needled into the stack without lowering the stack. Furthermore, these additional layers are preferably made entirely of stapled fibers.
