Abstract: Disclosed herein is an outboard motor including a power head having an engine, a propulsion leg extending downwardly from the power head, an input shaft housed in the propulsion leg and driven by the engine, a drive shaft housed in the propulsion leg, a propeller shaft in the propulsion leg and drivingly connected to the drive shaft, and a propeller mounted on the propeller shaft. The outboard motor also includes a transmission for drivingly connecting the input shaft and the drive shaft, the transmission being housed in the propulsion leg above the propeller shaft and selectively and alternatively driving the drive shaft in forward and reverse directions and providing two forward speeds.

Abstract: The device is so designed as to be cheap enough to be sold in large numbers and is particularly simple, compact and has a very low power consumption. It comprises a hydrokinetic converter and a gear mechanism having two forward speeds established by means of two pairs of pinions. It is completed by two clutches and a free-wheel disposed in the converter which provide the connection with the two input elements of the mechanism. These two clutches are actuated by a single slidable plate which moves as a function of parameters such as the speed of the vehicle or the load on the engine. The two clutches are disposed on opposite sides of the plate and one clutch is connected in parallel with the free-wheel.

Abstract: In a farm tractor of four wheel drive type, a speed change device for a power takeoff shaft projecting from a rear portion of a transmission case for driving a work implement attached to the rear end of the tractor is mounted in the rear portion of the transmission case, and a main shaft to receive output of the engine, a pinion shaft for driving the rear wheels and a transmission shaft for driving the front wheels are mounted in the front half of the transmission case with minimum spacing between the three shafts. This arrangement permits the transmission case to be compact in the vertical as well as transverse directions and provides a large space in the tractor underbelly for attaching a work implement.

Abstract: Apparatus for controlling the closing limit of a carburetor throttle valve in a motor vehicle engine. The apparatus comprises a vacuum-actuated device for varying the closing limit of the throttle valve in dependence upon the vacuum applied thereto; a vacuum line connecting the vacuum-actuated device with a source of intake manifold vacuum downstream of the throttle valve; a solenoid valve arranged in the vacuum line for controlling the vacuum transmitted by the line; and an electrical circuit for controlling the solenoid valve in dependence upon the gear shift position of the vehicle transmission.

Abstract: A two-speed power take-off drive having interchangeable output shafts for selectively reciprocating a cammed shaft for biasing elements shifting a clutch collar for the two-speed operation.

Abstract: A speed change mechanism for a transmission comprises a main shaft provided with a plurality of power transmitting gears, and a propelling speed change gear system and a power takeoff speed change gear system supported on the opposite sides of the main shaft in parallel thereto. Each of the propelling and power takeoff speed change systems includes a speed change shaft freely rotatably carrying a suitable number of speed change gears meshing with the power transmitting gears on the main shaft at all times. The speed change shaft accommodates an axially slidable speed change rod which, when moved, forces pins outward or inward radially of the shaft to couple the speed change shaft to the corresponding speed change gear or disconnect the shaft from the gear. The freely rotatable speed change gears are held against axial movement, while axially slidable engaging members which are otherwise provided between the adjacent speed change gears are eliminated.

Abstract: Additional propelling power for a bicycle is provided by mounting the bicycle seat to reciprocate in an up and down direction and converting this motion into rotary motion by a ratchet gear. Rotation of this ratchet gear takes place when the seat moves down under the weight of the bicycle rider, a compression spring returning the seat to its up position when the rider lifts his weight from the seat. The motion of the ratchet gear is imparted to the rear wheel of the bicycle through a gear train which amplifies the rotary motion and further which may be provided with a gear shift mechanism for varying the number of rear wheel rotations imparted for one down stroke of the bicycle seat. The auxiliary seat drive is provided in addition to the conventional pedal drive sprocket and chain arrangement normally provided on bicycles.
