  • Patent number: 4013873
    Abstract: An electrical heating farrowing pad of rigid plastic walls is adapted with shielding for either overhead supported outlets or side supported outlets along the floor of the farrowing pen. The shielding includes a tubular elbow fitting having one arm securely fixed between the rigid plastic walls of the farrowing pad, the elongated electric cord extending through the fitting. The electric cord is passed through an elongated tubular connector until the male plug extends from one end of said connector. The opposite end is aligned with the vertical arm of the elbow fitting and coupled to said arm to shield the cord for an overhead outlet. Alternatively, the horizontal arm of the elbow fitting is cut along a bias and a complementary bias cut is formed on the end of the tubular connector so that the shielding extends along the floor for connection to a side supported outlet.
