Abstract: This invention is an all gear continuously variable transmission that is non-dependent on friction. It can me be used in high torque applications. It offers a steady and uniform output for a steady and uniform input. It allows a co-axial input and output thereby by using a planetary gear system the output can be made continuous from forward to reverse. This uses a “scotch-yoke” mechanism to convert rotational motion to a linear reciprocating motion. The linear distance of this reciprocating motion-“stroke” is changed by altering the crankpin location of the scotch-yoke mechanism. This reciprocating motion is converted to a rocking motion by using a “rack and pinion” and later converted to a unidirectional motion via a One-Way-Bearing. A set of non-circular gears are used to achieve a steady and uniform output. It employs a very simple mechanism to change the ratio between the input and output of the transmission.

Abstract: A variable stroke crankshaft assembly includes a drive shaft surrounded by a sleeve. A crankshaft is disposed inside the drive shaft with the longitudinal axis of the crankshaft offset from the longitudinal axis of the drive shaft. A gear projecting outwardly from the crankshaft through a window in a drive shaft engages angled gear teeth on the inner surface of the sleeve allowing sliding movement of the sleeve relative to the drive shaft to rotate the crankshaft. A crankpin is attached to the crankshaft but offset from the rotational axis of the crankshaft. Rotational movement of the crankshaft with respect to the drive shaft thus pivots the crankpin with respect to the rotational axis of the drive shaft creating a crank stroke that may be varied by sliding the sleeve back and forth.

The lost motion mechanism also has a snow pack plate separably connected to the crank and linkedly connected to the drivepin for permitting the crank to rotate to a second predetermined position upon reversal of shaft direction in the event that a snowpack condition on the vehicle window prevents the wipers from moving to a full depressed park position.

Abstract: A variable length crank arm in a windshield wiper system provides a depressed park position for an associated wiper blade when the direction of rotation of a drive motor is reversed. The crank arm relies on an eccentric driver to vary its length between a first length and a longer second length. When the eccentric driver is rotated in a first direction to wipe the windshield, a spring loaded pin keeps the eccentric driver rotatably fixed to an output arm with the crank arm consequently at the first length. The spring loaded pin also engages a cam slot in a cam plate, the cam plate rotating freely with the output arm and the eccentric driver in the first direction. To move the blade to the depressed park position, the direction of rotation of the drive motor is reversed. This causes the cam plate to become rotatably stopped, with the now stationary cam slot forcing the pin out of engagement with the output arm.

Abstract: A windshield wiper system incorporates a depressed park mechanism that stores a wiper blade in a depressed, park position. Actuation of the motor in one direction moves the blade out of its park position and into an operative position where it reciprocates through a predetermined wipe pattern. De-actuation of the wipe system then repositions the blade in its depressed park position by simply reversing rotation of the motor and altering the effective length of the drive link assembly.

Lock pins in the connecting rod bore are selectively engageable with the sheave bores to fix the sheave to the connecting member.

Abstract: An exercise machine with a seat and two adjustable cranking mechanisms is disclosed. The first cranking mechanism has rotatable hand grips for grasping by the user's hands while the second cranking mechanism has rotatable pedals for engagement by the user's feet. This second cranking mechanism is located at a position vertically below the location of the seat, allowing the exerciser to use his or her body weight when pushing downwardly on the pedals. Additionally, each cranking mechanism is selectively adjustable to a plurality of exercise positions. This makes the machine adaptable to all exercisers regardless of their size and shape and permits the user to selectively vary the exertion required during the exercise.

Abstract: An exercise machine with a seat and two adjustable cranking mechanisms is disclosed. The first cranking mechanism has rotatable hand grips for grasping by the user's hands while the second cranking mechanism has rotatable pedals for engagement by the user's feet. This second cranking mechanism is located at a position vertically above the location of the seat. Therefore, the exerciser may not use his or her body weight when exerting pressure on the pedals. This machine exercises virtually all of a user's muscle groups, however, the configuration of the seat vertically below the second crank mechanism results in a particularly strenuous activity for a user's hamstrings. Additionally, each cranking mechanism is selectively adjustable to a plurality of exercise positions. This makes the machine adaptable to all exercisers regardless of their size and shape and permits the user to selectively vary the exertion required during the exercise.

Abstract: To allow compact design of a wiper system equipped with a wiping angle varying assembly which comprises an actuating motor, an eccentric cam member provided in a path of transmitting the movement of the output end of a wiper motor to a wiper arm, and a control unit for activating the actuating motor so as to move the eccentric cam member and thereby change the range of angle of the wiping movement by altering a configuration of a linkage structure provided between the wiper motor and the wiper arm, the control unit is adapted to activate the eccentric cam member with such a timing that the force transmitted through the linkage structure from the wiper motor to the wiper arm tends to assist the force produced by the actuating motor to move the eccentric cam member in the required direction. Thus, the requirement of the power output of the actuating motor can be reduced, and the actuating motor can be substantially reduced in size.

Abstract: A pedal crank has a throw adjuster comprised of two triangular frames in opposed relationship to a common triangular base that is variable in length. A pedal crank is formed with a peak of a proximal triangular frame attached to a crank axle and a peak of a distal triangular frame attached to a pedal axle. A fixed side of the proximal triangular frame is attached rigidly to the crank axle and a floating side of the proximal triangular frame is attached rotationally to the crank axle. A fixed side of the distal triangular frame is attached rigidly to the pedal axle and a floating side of the distal triangular frame is attached rotationally to the pedal axle. The fixed side of the proximal triangular frame and the fixed side of the distal triangular frame are attached to opposite ends of the common triangular base. Both sides of both triangles are attached pivotally to the common triangular base that is variable in length with a screw shaft, a fluid-operated cylinder, or other length-adjustment means.

Abstract: A windshield wiper apparatus for a vehicle includes a rotatably supported main shaft to which a wiper arm is secured, a main lever secured to the main shaft, a cam member arranged eccentrically about the main shaft, a plate turnably supported on the main lever, a subordinate lever having one end arranged about the cam member and another end connected to the plate, an arm turnably supported on the plate and having a joint to which a wiper drive mechanism is connected, and a turnover spring arranged between the plate and the arm for holding the arm at a predetermined position. If the wiper arm is moved by wind force during operation at high vehicle velocity, this motion is compensated for by adjusting the oscillation sweep of the arm in such a manner that the wiper arm will reverse direction at its normal upper reversal point. The wiper arm is thus prevented from striking the vehicle pillar, without reducing visibility through the windshield.

At the beginning of each step, the velocity of the carriage is zero. In the further course, it rises to a maximum at a crank angle of 90.degree., and drops back to zero at the end of the step. In this way an especially gentle and rapid motion is made possible. The crank pins may each be mounted on its own shaft, or they may be mounted together on a common shaft with an offset of 180.degree..
