Abstract: A braking system for an in-line roller skate includes a brake actuator arm pivotally mounted on a support shaft extending through the rearmost wheel of the skate. Brake pads are connected to a first segment of the brake actuator arm and extend behind the rear wheel. The brake actuator arm is continuously biased to maintain the brake pads, which are tire segments, out of engagement with the skate support surface. An upwardly directed force applied to the brake actuator arm by the skater pivots the arm relative to the in-line roller skate and brings the brake pads into contact with the skate support surface.

Abstract: A bicycle having conventional foot pedals with driving rotating cranks connected to a load is improved with arm pedals. Preferably, each foot pedal forms the point of attachment of a line under tension. The line from each pedal passes upwardly from the pedal to a seat sheave in the vicinity of the seat. Thereafter, the line from the pedal goes forwardly to a forward sheave mounted on the front of the bicycle frame. From the forward sheave the line runs rearward to a second seat sheave and dead ends at a point of attachment on the opposite pedal. Hand pedals are connected to the line from each pedal in that portion of the line between the seat sheave and the forward sheave. Operation of the hand pedals is synchronized with the traditional foot cycling motion of the foot pedals. Upward stroke of the foot pedals is assisted with tension in the connected running rigging from both hand pedals.
