ABSTRACT:
This invention concerns an improved bottle jack. The invention comprises in combination, an improved bottle jack having a handle, fluid, and pump means and the improved bottle jack comprising the following. A base with the pump means being operatively connected to the base. An anchor rod having a lower anchor rod end and an upper anchor rod end being located opposite the lower anchor rod end, the anchor rod being located proximate the pump means and being pivotably connected to the base at the lower anchor rod end, the handle being pivotably connected to the anchor rod at the upper anchor rod end. A spring collar yoke being removably and pivotably connected to the handle and to the pump means, the spring collar yoke being located proximate the upper anchor rod end, the spring collar yoke being capable of concentrically enclosing the pump means. Finally, a compression spring being removably and operatively connected to the base at the lower spring end, the compression spring being removably and operatively connected to the spring collar yoke at the upper spring end to align the compression spring, the compression spring concentrically enclosing the pump means, the compression spring being capable of vertical translation as the handle is vertically translated between an upper position and a lower position as loads on the handle are transferred to the pump means and as the pump means reciprocates and as the compression spring returns the handle to the upper position.
