Model of horse gear
- c. 1891
Model (scale 1:8) of horse gear, on wooden base
The model represents a compact and portable horse gear of the type once widely used for driving light machinery, particularly on farms. The horse connected by traces to the swingle tree at the end of the arm, walks in a circle. The motion of the arm is transmitted to a horizontal shaft (over which the horse must step) by a bevel gear. Outside the horse track is an arrangement of spur gears to increase the speed so that the belt driving the machinery may run at a convenient speed. The connection between the central gear and the multiplying gear was made with universal joints for ease of setting up.
