This machine has been designed for use of the wheel makers for facing off the sides of the spokes near the hub, to secure a true bearing for the flanges when pressed in. By this method, the position of the spokes and dish of the wheel are not changed when the flanges are forced up and each spoke is properly supported by the flanges, making a true and substantial job. The frame is cast in one piece with cored center. It is of neat design and very strong, occupying 2 feet x 4 feet floor space. It is fitted with a quick-acting tail stock operated by a ratchet lever. The right-hand tool-rest is attached to it and moves with the tail stock, so that it is always in proper position, requiring no adjustment when once set for a certain size wheel. Both tool rests can be adjusted in any direction for different sizes of wheels.
A friction pulley is used to drive the machine. It is instantly started when the operator's foot is applied to the pedal, which can be reached from either side of the machine. When the pressure is removed from the pedal the momentum of the wheel is immediately checked by an automatic brake. Its capacity is sufficient to receive wheels 60 in. in diameter and smaller with hubs of different diameter up to 14 in. long. The speed of the friction drive pulley is 180 turns per minute, and it has 12 in. diameter, 4 in. face, requiring a pulley on the main line with 4 in. crowning face.
