  • Patent number: 11254017
    Abstract: A mechanical positioning structure includes a first positioning mechanism, a fixing post arranged through a central axis of the first positioning mechanism, a first driving mechanism, a second positioning mechanism rotationally arranged on the fixing post and coupled to the first driving mechanism, a second driving mechanism, and a platform. One end of the first driving mechanism is fixed on the fixing post. Another end of the first driving mechanism is slidably arranged on the first positioning mechanism. The second driving mechanism is arranged on the second positioning mechanism. The platform is arranged on the second driving mechanism. The first driving mechanism drives the second positioning mechanism to move on a surface of the first positioning mechanism and rotate the second positioning mechanism around the fixing post. The second driving mechanism drives the platform to move on the second positioning mechanism.

  • Publication number: 20130269458
    Abstract: Drive structure is provided for connection between an actuating assembly of a circuit breaker and linkage structure for opening and closing a movable electrical contact disposed in a volume of insulating material in a pole assembly. The drive structure includes a drive lever constructed and arranged to connect with the at least one actuating assembly. A drive shaft has first and second ends, with the first end being removably coupled to the drive lever so that rotation of the drive shaft rotates the drive lever. Seal structure is disposed between the drive lever and the actuating assembly such that the drive shaft can be removed from the drive lever without disrupting the volume of insulating material.

  • Patent number: 7717103
    Abstract: An arrow rest assembly is connected to an archery bow so that an arrow rest is: (i) positioned to support the shaft of an arrow nocked and ready for drawing or drawn and ready for shooting, (ii) positioned to support the shaft of the arrow during an early portion of shooting of the arrow by the bow, and (iii) to allow substantially unimpeded passage of the fletching of the arrow during only the latter portion of shooting of the arrow by the bow. The arrow rest assembly exerts only substantially negligible force on any cable of the bow when the bow is drawn.

  • Patent number: 7018181
    Abstract: A piston pump assembly with a rotatingly driven swashplate in driving relationship with a rocker arm and piston engaged with one end of the rocker arm. A spring urges the rocker arm and piston into contact with an annular ring carried by a bearing in the swashplate. The spring may be a separate leaf spring or may be formed integrally with the rocker arm. The rocker arm engagement with the piston uses a spherical ball-joint-like surface. The contact between each of the rocker arm and piston and the annular ring utilize spherical surfaces on the rocker arm and piston, with an elongated footprint on the rocker arm and a circular footprint on the piston. The piston is allowed a slight radial play in operation.

  • Patent number: 6415912
    Abstract: The driving mechanism has a drive shaft which rotates a driving block. A cam is mounted for rotation to the driving block and is received in a slot of a follower. As the cam rotates, it rolls backwards and forwards in the slot and causes the follower to rotate. A connecting rod is affixed to the follower and is rotated by it. The connecting rod rotates about an axis parallel to, but offset from, the axis about which the drive shaft rotates. The rate of rotation of the drive shaft is unvarying whereas the connecting rod rotates at a varying rate. A crank is affixed to the connecting rod and imparts reciprocating motion to the tray. A link can be substituted for the cam.

  • Patent number: 5934158
    Abstract: A differential drive mechanism comprises a cage (1), which is rotatable about an axis (3) and represents the input, two coaxial output shafts (12, which are rotatable in respect of the cage (1) about the axis (3), a coupling (4) which is connected eccentrically through two output shafts (12) to transmit relative contra-rotational movement between them by connections which permit relative rotation of the coupling (4) and the output shafts (12). The eccentric connection of the coupling (4) on the ouput shafts (12) includes a respective eccentric hole (9) in the inner end (10) of each output shaft (12) in which the associated end (6) of the coupling (4) is received. The ends (6) of the coupling (4) have a part-spherical engagement surface. A slipper (8) affording a complementary part-spherical internal surface is received in each eccentric hole (9) and each engagement surface is in engagement which a respective complementary internal surface.

  • Patent number: 5495779
    Abstract: A differential gear is disclosed in which neither the clutching device which connects the output elements to a bearing block, which is set rotating by means of a drive element, nor the output elements, include a toothed rim. Each of the two output elements is provided with one connecting link having connecting points which lie eccentrically to the axis of rotation of the output element and which connect with the clutching device. The clutching device includes a coupling link, which is mounted in the bearing block so as to rotate around an axis, which extends perpendicularly to the axis of rotation of the bearing block between the two output elements.

  • Patent number: 4750094
    Abstract: A self-contained device which simulates the appearance of an operating alarm system actuating component is disclosed. The device has a face plate similar to face plates for key operated or switch operated alarm systems. The face plate also has a light mounted thereon and a self-contained power source for illuminating the light. The device can be mounted to the exterior surface of a building or doorjamb and actuated, such as by a key operated switch, so that the device simulates the appearance of an operating actuating component for a real alarm system.

  • Patent number: 4291591
    Abstract: Motion transmitting apparatus includes a case member, a pair of coaxial shaft members, and a pair of shuttle members. The members rotate about the shaft axis in unison as a differential mechanism, with differential action between the shaft members provided by oscillation and reciprocation of the shuttle members in opposite directions relative to another axis perpendicular to the shaft axis. Grounding the case member causes this opposite oscillation and reciprocation of the shuttle members to provide a reversal of the direction of rotation of the shaft members.

  • Patent number: 4161137
    Abstract: A rocker wheel jack is arranged on a compact frame so that the driving mechanism is placed below the rocker wheel. The mechanism is adjustable so as to vary the spacing between it and a drive wheel. The rocker wheel is adjustably spaced from the drive wheel. A pitman connects the drive wheel and the rocker wheel. The pitman connections to the wheels are further adjustable radially to the wheels. Thus a jack is provided with a possibility of multiplicity of adjustments and a minimum of vertical space and of weight for the jack. The complete unit is readily movable. The driving mechanism is readily accessible for repair or replacement. An oil level sensor is provided in the well with connections transmitting its output to the R.P.M. of the jack.
