Abstract: An apparatus for repairing articles, such as jet skis, and including a pair of rings which are disposed in a parallel, spaced relation and connected together by a group of braces of adjustable length. Each ring is provided with a pair of flats, and the flats on one ring are oriented with the flats on the other ring. A support member extends generally chordwise across each ring, and is provided with a recess or cradle, and the ends of the water ski are received within the respective recesses. A clamping member, such as a rachet take-up belt, is associated with each ring and clamps the end of the jet ski against the respective support member. The jet ski in an upright condition is clamped to the respective support members and the rings are then manually rotated to invert the jet ski and enable the lower surfaces of the ski to be worked on. Engagement of the flats with the supporting surface maintains the rings in a position such that the jet ski is upright or inverted.

The upper and lower casings have radially movable pieces with clamping members thereon. A synchronous moving unit moves the movable pieces relative to the upright post to define a distance which is equal to a radius of curvature of a curved plate that is to be clamped and drilled by the device.

Abstract: A tube end preparing apparatus for precisely preparing the ends of tubes, including bent tubes. The apparatus includes a reference mechanism, a tube clamping mechanism, a cutting mechanism, and cutting head control mechanisms. The reference mechanism and tube clamping mechanism combine to precisely locate a flow tube with respect to defined reference indicia. The entire locating and clamping process not only provides accuracy and symmetry in aligning and clamping the flow tube relative to the desired reference indicia but can be accurately repeated with speed. The cutting mechanism includes a rotating cutting head mounted for longitudinal movement on a carriage. A control system controls the feeding movement of the carriage as the cutting head nears the end of the flow tube. A first stop mechanism causes a plunger to contact a micro-switch to stop the longitudinal movement of the carriage. A second stop uses a hard stop to prevent the carriage from overtravel due to momentum.

Abstract: A vacuum chuck particularly suited for use with optical fibers includes a V-shaped channel provided with "hold-down" suction and extending across the middle of a plane surface for placement of an optical fiber. The V-shaped channel is formed by abutting chamfered edges of two metal, solid rectangular jaw blocks. Slots along the abutting sides of the jaw blocks extend away from the chamfered edges to form passages for applying suction to the V-shaped channel for retention of the fiber therein. The passages are centered in the channel and the suction drawn through them pulls the fiber directly down into the V-shaped channel for precise centering therein. The top surfaces of the jaw blocks form a plane surface which extends laterally onto the shoulder of a support base. The generally planar surface facilitates placement and visual confirmation of the alignment of the fiber thereon and further permits mechanical securing of the fiber by tape or other means so that suction is not continuously required.
