Abstract
A blocking device for an overhead conveyor having a combined limit stop and shock absorber which acts to define the end positions of a drive device which moves the blocking device between an operative and an inoperative position. The combined shock absorber and limit stop device comprises a body having two parallel plungers sliding in parallel bores of the body, the bores being linked at their closed ends by a passage having a restrictor throttle therein, the interior passage and the chambers are filled with oil which, upon its passage through the restrictor throttle, when one of the plungers is depressed, dissipates energy causing the depression and also serves to push out the other plunger ready for a subsequent depression when the device moves from one position to the other.
