Abstract
An apparatus for converting expended thermoplastic material, specifically empty plastic bottles, into artificial rocks, by placing the empty thermoplastic bottle in the apparatus between two sliding carriages, on each of which a rock has been mounted; and each carriage attached to a hydraulic jack, which, when the handle is pumped, moves the carriage toward the bottle which has been heated to malleability by heat lamps mounted above and sideways to the bottle, and the said heated, flexible bottle is squeezed between the two rocks mounted on the carriages, and then the bottle is rotated and the process repeated to give the bottle a rock shape. The rock shape may be further altered using a portable heat gun.
Claims1
An apparatus for converting an expended plastic bottle into a rock comprising:
- (a) two separate carriages onto each of which a real rock is mounted,
- (b) each said carriage mounted on rollers and attached to a hydraulic jack,
- (c) each said hydraulic jack moves back and forth by means of a handle mounted on the jack to push said rock containing carriages back and forth,
- (d) a turntable mounted in between the two said carriages for placement of a plastic bottle,
- (e) a heat source to melt the plastic bottle to a malleable point, comprising two heat lamps mounted on each side of said turntable, each of which has a switch to turn it on and off,
- (f) each said heat lamp connected to the electric source by a flexible electric line.
