Abstract: A support for mounting a camcorder, a motion picture camera, or the like on a boat mounted pylon holding a tow rope to an object such as a water skier automatically tracks movement of the water skier. A clamp fastens to the pylon and holds a rod extending upwardly offset from the pylon. A turning stand is mounted for panning rotation above the rod. A platform is pivotally mounted for tilting on the turning stand and can rotate with the turning stand. The platform is located at a level above the pylon. A guidance arm extends rigidly from the platform over the tow rope in an axial direction for attachment thereto at a location spaced from the pylon. The platform can pan in response to lateral movement of the tow rope.

Abstract: A portable work station provides support for an article to be used by a person occupying available funiture. The work station has a base adapted to fit beneath the person. Preferably, the base has an axis of rotation and extends laterally therefrom. The base can rotate from an upwardly facing position on one side of the axis to an inverted position on the opposite side. An adjustable arm has a common axis of rotation with the base and extends laterally therefrom to a remote end. The base and the adjustable arm can rotate independently of each other or can be interlocked in a fixed relationship relative to each other so that the base and the arm extend in perpendicular planes. An article supporting portion is connected to the remote end of the adjustable arm. The article supporting portion can be positioned for holding the article and the portable work station can be positioned for either right or left handed applications.

Abstract: A snelled fishhook case has a spool and a sleeve that fit coaxially together, each being rotatable relative to the other about the common axis, with the sleeve positioned about the spool. A radial opening in the sleeve and an axial slit in the spool can be aligned in registry to provide radial access to a spool cavity that receives the whole hook portion of a snelled fishhook. An annular space is defined between the spool and the sleeve and extends axially opposite the sleeve opening. The leader portion of the snelled fishhook can be wound or unwound about the spool in the annular space covering the spool slit.

Abstract: A tool for pulling a speed reduction unit from a drive shaft includes a puller plate that has outwardly extending flanges adapted to be placed in a groove formed in the internal surface of a tubular mounting sleeve of the reduction unit so that, when a threaded rod is threaded through the plate to extend into the sleeve and the inner end of the rod abuts the end of the drive shaft on which the tubular sleeve is mounted, continued threading of the rod into the mounting sleeve causes the plate to react against the wall of the groove and force the mounting sleeve and the reduction unit carried thereby off the drive shaft.

Abstract: Two eccentric weights of a vibrator are mounted, respectively, on two coaxial shafts, one of which is a hollow shaft mounted on the other shaft. The two shafts can be connected for rotation in unison, and can be separated for relative rotation to alter the angular relationship between the weights. Mechanism is provided to alter the angular relationship between the weights while both shafts continue to rotate. The hollow shaft and the other shaft are connected, respectively, to one end of two beveled gear trains which can rotate as a unit about the axis of the shafts. By changing the angular relationship between the gears at the other end of the gear trains, the angular relationship between the eccentric weights, and hence the stroke of the vibrator, can be changed.

Abstract: Adjacent links of a chain are releasably locked together by a pin, which is inserted through the pivot joints of the chain. The pin has spaced apart shoulders which engage the outer surfaces of the outer links at the pivot joints when the pin is fully inserted in the links. The pin has a front end which is compressible to permit passage of the forward locking shoulder through the inner and outer links of the chain.

Abstract: A two-mass heavy duty vibratory machine has a frame in the form of a box-like cage in which a working member, such as a screen, is received. In one embodiment of the disclosure, the frame is resiliently mounted on a stationary support surface and the working member is resiliently suspended from the frame. In another embodiment of the disclosure, the working member is resiliently mounted on the stationary support surface and the frame is suspended from the working member. In both embodiments, an exciter is mounted on the frame at a location outside the frame and spaced from the working member.

Abstract: There is disclosed a multi-lane destacking machine in which stacks of nested articles in each lane are fed, one at a time, through an opening to drop to a shuttle platform. A clamp mechanism grips a stack on the shuttle platform, and the platform is retracted. A stripper mechanism, which has sharp, pointed edges on stripper arms to penetrate the interstice between the bottom article and the article nested therewith, advances to dislodge the bottom article of the stack onto a surface in front of the retracted shuttle platform. When the shuttle platform is advanced to again support the stack upon release of the clamp mechanism, the previously dislodged article is moved from under the stripper mechanism into a discharge lane by the shuttle platform. When the stripper mechanism is retracted, the stripper arms, which are normally biased toward each other, engage a stationary stop to spread apart.
