  • Patent number: 5749323
    Abstract: A slat for forming a flooring structure for a hog pen and particularly the area under the sow in a farrowing crate is rectangular with side edges which abut side edges of adjacent slats to align the slats in a row. Each side edge has tabs projecting outwardly to interlock above or below tabs on the next adjacent slat to prevent lifting of the slats. The slats have slots parallel to the end edges. The tabs at the side edges are arranged with spaces therebetween so that when abutting slots are formed between the slats which are at right angles to the slots in the slats. Each slat has a rib along its end edges raised from the upper surface with that rib being defined by an inner edge which is at right angles to the upper surface and a smoothly curved top edge and gradually inclined outer side so that the piglet can lie on the rib without discomfort but can gain purchase against the inner side to push inwardly onto the slat for suckling.

  • Patent number: 5709631
    Abstract: A stationary exercise support apparatus for a wheelchair comprises a frame with a pair of horizontal rollers across the frame onto which the wheelchair can be rolled to sit cradled between the rollers. Rotation of the rear wheels of the wheel chair thus drive the rollers while the wheel chair remains stationary on the frame. The wheelchair is held in place by a pair of guide wheels mounted inside the rear wheels of the wheelchair on a support plate behind the rear roller so that the wheelchair is prevented from side to side movement. The wheelchair is held against forward movement off the cradling rollers by a third roller positioned forwardly of the front roller which can be raised and lowered by a handle at one side to a lowered position in a common horizontal plane with the first two rollers in which the wheelchair can roll off the cradled position to a raised position preventing forward movement of the wheelchair.

  • Patent number: 5640926
    Abstract: An adjustable feeder includes a first arrangement which acts as a dry feeder and provides two vertical slides (31) each on a respective side of a hopper (22) which is simultaneously vertically adjustable by straps (41) at the ends of the hopper. In a second arrangement the same adjustment system is used with a shelf type feeder so that the shelf (60) can be adjusted between a lower position for small animals and a raised position for large animals and the slides (31) can move vertically to accommodate the change in height of the shelf (60) and to adjust the distance of the slides (31) from the shelf (60) to control the feed flow.

  • Patent number: 5092271
    Abstract: A heating pad for example for animals particularly piglets in a farrowing crate comprises two vacuum formed sheets which lie parallel one on top of the other with a shallow compartment therebetween. A pipe where heating fluid passes into the compartment through the lower sheet and wraps around a number of projections in the lower sheet which extend from the lower sheet up to the under surface of the upper sheet. The pipe is of a flexible elastomeric type resistant to corrosion so that the pad is thus heated by a warm liquid such as water which provides a very simple economic device resistant to damage.
