Abstract: A fuel-saving traveling system for an internal combustion engine-driven vehicle has a one-way clutch in the drive train allowing the wheels to overrun the engine.

Abstract: A hand tool having a motor rotating a drilling bit is made more useful by a power transmission collar. An auxiliary tool, such as a riveter, scheduled for use selectively during intervals between drilling operations, is powered by the electric drill. The auxiliary tool has a driven member with a well adapted to receive the bit. A power transmission collar is secured to the bit near the chuck of the drill. The collar has self-guiding spiral surfaces and pin-engageable surfaces. The driven member has a socket featuring a single pin toward which the spiral surfaces guide the collar to the pin-receptive surface for the power transmission connection.

Abstract: A clutch comprising a pair of spring loaded shoes and a drum, somewhat like brake shoes and a drum, applies and removes loads upon an automatic transmission. As the motor speed picks up, the shoes are flung outwardly under centrifugal force. When the speed is great enough, the shoes grip the drum and turn it. The drum drives the automatic transmission. Under runaway conditions, the drum is rotated by the load acting through the transmission. When the load drives the drum even faster than the motor rotates the shoes, slippage occurs in the clutch and the motor is relieved. This way the transmission may be shifted up or down at any speed. The clutch utilizes one or more shoes with a relative high coefficient of friction on one side and a lower coefficient of friction on the other side. A driving notch within the clutch directs the higher coefficient lining on the shoe to drive the drum and directs the other lower coefficient lining when the drum is rotating faster than the motor, such as in a runaway condition.

Abstract: A bicycle having front and rear wheel caliper brakes each being connected by a cable to a linkage including a swingable cam element which is normally disposed in the path of travel of a cooperating cam member mounted for movement concentrically about the pedal axle whereby the cam element through its swingability is removed from such path during forward pedaling action and is lockingly engageable with such cam member upon back pedaling action. In the latter condition force is applied to the linkage for effecting a pull upon the cables to effect braking operation. The cam members are so related to the pedal cranks that when engagement with the cam element is effected one pedal crank will be downwardly directed whereby a support stand carried upon the associated pedal may cause such pedal to swing to present the support stand for engagement with the support surface.
