Abstract

Improvements in safety devices for elevators, which have a carrier jack designed to prevent any accidental fall of the piston carrying the load, characterized in that a crown is arranged around the piston with a slight play and kept fixed at two points of its periphery distant of an arc inferior to a semi-circumference, being such the thickness of this crown and the diametral game that the inclination of the crown in relation to the generatrices of the jack interferes, by interposition, the movement of the piston in the direction of descent; a means being arranged so as to, at will, maintain the said crown in a plane perpendicular to the axis of the piston, or let it take its oblique position interrupting the descent.
