发明名称 Orchard lifts
摘要 An orchard lift apparatus including a bicycle-type seat upon which an orchard worker may sit, said seat mounted on an elongated pole passing upward through a sleeve and friction hemisphere, said hemisphere resting within a socketed bridge through which said sleeve passes downward, a cable, attached to said sleeve-hemisphere unit, extends downward, approximately parallel to said pole, and is wound or unwound by the worker, on a drum at the base of said pole, by means of foot pedals. Whereby, the worker may move upward or downward, and may change the attitude of the seat in any direction, two straight poles or tubes constitute the legs, angling inward in an upward direction, the above mentioned socketed bridge rigidly fastened to, and spanning across the tops of said pole legs. Two arms attached near the tops of said pole legs, extending forward for three or more feet, and coming together to provide support and fastening for a more or less vertical board, slat, or rod, which is positioned against any convenient branch or crotch in the tree to support the orchard lift at an appropriate angle.
