ABSTRACT:
For producing a copy in settable material such as plastic of an object, for example for repairing one side of a vehicle such as an automobile, truck or boat to correspond to the shape of the other side, a tracer mechanism is provided which is secured on one side and a copying mechanism on the other side, the two being connected by a plurality of flexible tubes. On the tracer side there is a frame on which is longitudinally slidable a carrier in which is secured a tube with a piston slidable therein, and a support connected to the piston. Secured at their ends in the support and slidable through openings in the carrier are a plurality of tubes, in each of which is slidable a piston connected to a spline which extends below the support. The free ends of the splines carry a shaping member formed of flexible material. The support on the tracer side is provided with wheels which roll on the surface to be copied.
On the copy side, there is likewise a frame on which a carrier is slidable, the other end of the support tube being secured in this carrier and being connected to a support through a reversing mechanism. Likewise, the spline tubes pass slidably through the carrier and their ends are connected to the support. On the copy side, there is likewise a flexible shaping member connected to the ends of the splines which are in themselves connected through the reversing mechanism to the pistons in the spline tubes.
Arrangements such as suction cups are provided for mounting the frames on the tracer and copy sides.
