A method of using the jerk string device to move duck decoys 48 on a jerk line 38 connected to the elongated slider 20.

A linear powered input device that utilizes linear input from a user and converts the linear input rotational energy to perform work. The linear input is generated by lever arms having a slotted attachment at a pivot point that allows a free end of the lever arms to move linearly rather than in an arcuate path. The lever arms are connected to a power transmission mechanism that wraps around one or more drive wheels having one-way bearings mounted on one or more output shafts. The output shafts can be connected to any type of auxiliary device to perform the desired work. Output wheels may be mounted on the output shafts and operatively connected by a transmission link that allows linear motion of any lever arm in any allowable direction to cause the output shaft to rotate in the same rotational direction so as to receive continuous input.

A rotary to linearly reciprocating motion converter includes a case, a closure member engaging an opening of the case to dispose a pinion gear rotatably coupled to the closure member, the pinion gear having half the diameter as an interior ring gear of the case, and further includes a pinion shaft connected to the pinion gear on a first side of the closure member and to an inboard end of a crank arm on a second side of the closure member, the outboard end of the crank arm having a force transfer member aligned with a point on the periphery of the pinion gear. Rotation of the closure member relative to the case results in the force transfer member moving in a linearly reciprocating mode. The force transfer member may be coupled to a conveyor to reciprocate the conveyor as the closure member rotates.

An accelerator device includes an inner housing, a pedal lever, an urging member, and an actuator. The inner housing is supported to the outer housing by a support member. The pedal lever is rotatably supported to the inner housing in response to a stepping operation. The urging member urges the pedal lever in a closing direction. The actuator can drive the inner housing in an opening and closing directions of the pedal lever.

A digital display and a digital time device are provided, which includes a housing, a drive assembly, display assemblies and a mainboard assembly. The housing is provided with seven windows arranged to form the shape of the character “”. The mainboard assembly is fixedly connected to the housing and is located behind the windows. Seven curved grooves are provided inside of the drive assembly. The display assemblies include display sheets and pull rods. One end of each pull rod is fixedly connected to the display sheets. The display sheets are slidingly connected to the mainboard assembly. There are seven display assemblies. Each pull rod is slidingly connected to the curved grooves in one-to-one correspondence, and each display sheet is one-to-one correspondence with the windows. The present invention can achieve many advantages, such as low power consumption, great waterproof, strong moisture resistance capabilities and high stability.

A drive unit for motor vehicle applications, in particular motor vehicle closing devices. The drive unit comprises an electric motor and at least one drive element driven by the electric motor. In addition, an actuation lever that cooperates with the drive element is provided. The drive element and/or the actuation lever are advantageously designed to be able to rotate about an axis. A rotatably mounted intermediate element is provided between the drive element and the actuation lever. According to the invention, the intermediate element is in the form of a friction-reducing rolling element.

The present disclosure relates to the technical field of olive picking machines, in particular, to a double-swing-rod mechanism and a fruit picking machine using same. The double-swing-rod mechanism includes a supporting main body used for rigidly supporting a fruit picking machine, a rotating shaft component connected to the supporting main body, two conical gears that axially rotate around the rotating shaft component, two swing rods movably connected to the two conical gears respectively to achieve a swing effect, and a drive gear movably connected to the supporting main body.

A universal driving device includes a sun gear rotatably provided; a ring gear disposed on a rotation plane coplanar to a rotation plane of the sun gear and provided so that a rotation shaft of the ring gear is movable relative to a rotation shaft of the sun gear; and a gear train engaging the sun gear to the ring gear and configured to allow a relative motion between the rotation shaft of the sun gear and the rotation shaft of the ring gear and define a continuous power transmission state between the sun gear and the ring gear.

A knife drive assembly for use in a harvesting header may be mounted near the center line of the cutter bar of the header. Mechanical power from the power unit behind the header (typically the combine power output shaft) may be translated for application to two knife assembly sections in the cutter bar at the front of the cutter table. Movement of the two knife assembly sections with this apparatus can be fully synchronized and 180 degrees out of phase, to maximize cutting effectiveness and minimize vibration of the header. The unitary drive assembly may allow for rapid repair and manufacture, and the size and weight of the knife drive assembly may represent a significant weight and balance advantage over the prior art.
