Description

ing carried by said head over which said member operates and means for supplying fluid under pressure into said fixed cylinder.
3. An elevatorincluding a support, a vertically movable platform, a bracket on which said platform is mounted, a pair of telescopically arranged cylinders, one being fixed to and upstanding from said support and having its upper end-open and the other bein movable and working over said xed cy inder, a head closing the'upper end of the movable cylinder, bearings carried b said bracket and running on said movab e cylinder Which forms a track therefor, a frame carried by said head, sheaves carried by sai frame,'flexible members operating over said sheaves and connected at one end t9 the plat.- form and at their other ends to an anchor and means for supplyino' fluid under pressure' body and having its 'upper end open, a cylinder telescoping over the fixed cylinder and movable relative thereto and having its upper end closed, bearings carried by and movable With said movable cylinder, a platform support, a platform carried thereby, bearings carried by the platform support and movable along said movable cylinder, flexible members having connection at one end to the platform and at their other ends to a fixed anchor and operative over the bearings carried by the movable cylinder and means carried by said body fory introducing fluid under pressure from-saidcontainer into said fixed cylinder.
' 5. An elevator including a portable body, a fluid container carried thereby, a cylinder upstanding from saidv body and having its upper end open, a cylinder telescoping over the fixed cylinder and movable relative thereto and having its upper end closed, bearings carried by and movable with said movable cylinder, a platform support, a platform carried thereby, bearings carried by the platform support and movable along sa1d mov- `able cylinder, Hex-ible members having connection at one end of the platform and'at their other ends to a fixed anchor and operative over the bearings carried by the mov- -able cylinder and'means carried by said body with said movable cylinder, a platform support, a platform carried thereby, bearings carried by the platform support and movable along said movable cylinder, vflexible members having connection at one end to the platformand at the other ends to a fixed anchor and operative over the bearings carried by the movable cylinder and means carried byv said body for introducing fluid under ressure from said container into said' fixedp cylinder, said means'comprising a pump having a suction line leading from said container and a fluid pressure line leading into the fixed cylinder and a valve contro lled branch line leading from the fluid pressure line into said contamer.
7. Anfelevator including a truck body, telescopically arranged cylinders, the lower -end of one being fixed to said body, a head closing the upper end of the other cylinder,
a frame fixed to said head, load supporting n means a f xible member one end of which is attached t said, body and the other` end of' Which is attached to said means, a bearing carried by said frame and over which the flexible `member operates, and means for' introducing fluid under pressureinto and for relieving the Same from said cylinder.
In testimony whereof I have signed my yname to this specification.
