Abstract
A safety glove for use with a meat cutting machine that has a gripping roll and an elongated skinning blade utilizes a glove shell having hollow thumb and finger elements, and a hand compartment. The glove is comprised of a flexible insulation material and has a battery and wireless signal transmitter mounted thereon. First and second wires extend from the battery and the transmitter and these wires are wound around each other and have a layer of insulation on the outer surfaces thereof. The wires are embedded in close proximity to each other within the glove shell by virtue of being wound around each other so that if the glove is cut with an electroconducting instrument, such as the blade of the skinning machine, the wires will be electrically connected together. This occurs either through direct contact of the wires with each other, or by contact of each wire with the skinning blade, whereby the transmitter will be energized and will transmit a wireless signal to a receiver on the machine which is programmed to immediately stop the rotation of the gripper roll. The wires are formed into a plurality of loops which extend around the thumb and finger elements as well as the hand com…
