Improvements introduced in the object of the main patent no. 230,292 for improvements in portable pneumatic elevators, essentially characterized by having provided a deposit of appropriate shape and size, located in the space that the arms leave each other, and, when these rise, by the force of gravity, lower the contained lubricant, by means of a tube integral with the piston rod and a connector or terminal that connects it with the upper part of the piston or working piston, forcing it to exit between its adjustment segments, in order to, in this way, without the need of other mechanisms, keep the working cylinder properly lubricated during its operation.
