发明名称 Centrifugally cast pole comprised of a reinforced resin for supporting a light or the like upon an end thereof
摘要 A reinforcement for a centrifugally cast, synthetic resin pole comprises a woven wire cloth interposed between a mat and an inner layer of a fibrous material. The mat is permeable to the synthetic resin and has a specific gravity lower than the specific gravity of the synthetic resin so that when the pole is fabricated, the mat and the entire reinforcement float on the synthetic resin and are ultimately disposed in the interior of the pole wall. Means for securing a lamp or the like to the pole, such as set screws or collar bands, penetrate the pole only to the woven wire cloth so that further penetration is prevented when the pole is swayed and any wobble or play between the lamp and the pole is avoided.
