    Abstract: A skate structure including a cylindrical braking member mounted on a transverse horizontal shaft. A radially extending bolt is countersunk into the shaft and extends upwardly through a slot in the toe of the skate's foot plate. A groove in the foot plate above the slot receives a nut and prevents the nut from turning during tightening of the bolt, which threadably passes through the nut. The braking member is firmly received in a downwardly and forwardly extending socket which communicates with the slot.
