Abstract
Lever-mounted brake pads are applicable to two non-swiveling wheels at the rear of a hand truck. The pads are normally spaced away from the wheel treads by return springs. A foot pedal at the front of the truck is operable between two positions, one of them being a 'brake off' position, and the other being a 'brake on' position. Cranks are connected to the pedal and have links and cables associated with them and with the brake pad levers whereby the pedal, operating through the cables, is useful to either simultaneously apply both brakes in one pedal position, or simultaneously release both brakes in the other pedal position. The return springs keep the cables taut when the brakes are off. An over-center arrangement on the cranks and links, together with an appropriately positioned stop in the 'brake on' pedal position self-energizes to keep the brakes on until intentionally released.
