The rear end of the machine is mounted upon two wheels. A trough, with a runner-like bow, containing some adhesive matter, is suspended upon each side of the row. A vibrating arm or beam, carrying wisps or brushes, is adjustably suspended form the farm, and as the machine is pushed along the row of plants the insects are shaken into the troughs, from which they are unable to escape.

The machine is supported upon two wheels, one in the rear of the other. The body is hopper shaped, with a pair of crushing-rollers at the bottom. At each side there are revolving-wings, which sweeps the insects into the hopper, and in addition to these there are two gathering-fingers, which support the vines during the passage of the machine.

"The Leyden jar and discharger. Its discovery is attributed to the attempt of Musschenbrock and his pupil Cuneus to collect the supposed electric 'fluid' in a bottle half filled with water. The bottle was held in the hand and was povided with a nail to lead the 'fluid' down through the cork to the water from the electric machine. The invention of the Leyden jar is also claimed by Kleist, Bishop of Pomerania." -Hawkins, 1917
