Abstract: The present invention discloses a new and useful clamping arrangement for use in an upstanding drapery manufacturing device including frame means; a vertically adjustable trolley means; reference means defining a horizontal reference plane adjacent the lower end of the frame means and carriage means upon which are mounted marker means and cutter means for horizontal movement with respect to the upstanding frame along the reference means.The improvement provided by the present invention comprises combining with such present device an elongate clamping means located adjacent the lower end of the frame to secure the lower end of a length of fabric as it is being marked and/or cut. The clamping means provided includes an elongate clamping base secured to a transverse support member adjacent the lower end of the frame, an elongate clamping bracket pivotably connected to the clamping base to close on a clamping bar to secure the lower portion of a length of fabric.

Abstract: A brush mowing attachment to be secured to a tractor including a bracket assembly, for example a yoke adapted to be secured to the tractor, an extendable retractable outrigger arm arrangement connected to the yoke by pivot means located below the body of the tractor where the pivot means permits the outrigger arrangement to be selectively pivoted in a horizontal and a vertical plane, where the outrigger arrangement is adapted to carry a mower device and be selectively extended outwardly from the tractor and retracted toward the tractor, including means to selectively raise and lower the outrigger arrangement. Also, the outrigger mower device can be adapted for pivotal movement in a vertical plane.

Abstract: A pair of thermoplastic workpieces are spin welded by placing one element in a non-rotatable, reciprocable clamp. Another workpiece is press-fit onto the first workpiece and the clamp is shifted toward a continuously rotatable collet having radially inwardly closable jaws. A mandrel extends from the collet and projects beyond the jaws to guide the workpieces between the jaws. The mandrel is axially inwardly displaceable by the workpieces, with inward movement thereof being yieldably resisted by a spring to insure that radial shoulders on the workpieces are in abutment. When the other workpiece is positioned between the jaws, the jaws are closed radially into driving contact with such workpiece to substantially instantly rotate the latter at the speed of the collet relative to the one workpiece. Frictional heat thus generated melts the interface between the workpieces. When the other workpiece is released from the jaws, it adheres to the one workpiece.
