  • the flexible hose or conduit 56 may have its free end connected to the domestic water supply for the bathtub or to any other source of fluid supply.
  • the valve member is lifted manually either by the control knob 58 or operating member 68 until the stop member or ring 66 limits such lifting movement by engagement with the valve body member 49.
  • This lifting movement positions the annular space 63 to provide communication between the water inlet 54 and the conduit 52 so that the fluid supply flows through the valve and into the working pres.- sure cylinder 46. Water under pressure entering .the working pressure chamber 46 will cause the reciprocal cylinder 22 to move upward on its supporting member 8 thereby raising the seat member 38 to any desired ele-.
  • vated position but preferably to a position which is above the rim of the tub. If the operator, or user fails to turn off the fluid supply, the reciprocal cylinder. 22 will be limited in its upward movement by engagement of-the arm portions 39 with the ends of the cross rod 18.
  • the apparatus may be designed such that it is not necessary to turn off the fluid supply to limit upward movement of the reciprocal cylinder 22 but the latter may be permitted to lift until the arm portions 39 stop its upward move-.
  • the seat member 38 and reciprocal cylinder 22 may now be swiveled or rotated on the supporting post 7 to move the seat member outward over the rim of the tub.
  • a patient or person desiring to bathe or be bathed now positions himself on the seat and maybe rotated laterally to a position overlying the inside of the tub or the tub recess.
  • the attendant if there is one, may then move the hand knob 58 downward as far as itwill go which positions the annular chamber 50 and the port 59 in registry with the conduit 52 thus communicating the pressure chamber 46 to the outlet conduit 65 which discharges the fluid in the pressure chamber 46.downward through'the tubular extension 65 into the tub.
  • the piston member 8 is rearwardly inclined relative to the general plane of the base 2 so that the applied forces between the piston member 8 and cylinder 22 will tend to be concentrated at the upper rear and lower front of the piston member 8 as indicated by the location of the bearing materials 27 and 33.
  • the tubular extension 65 When the patient has bathed or been bathed, the tubular extension 65 may be lifted either by an attendant lifting the knob 58 or by the patient operating the operating member 68. This upward movement will position the annular recess 63 in communication with the inlet 54 and with the conduit 52 so that fluid from the source of supply feeding through the conduit 56 will discharge into the pressure chamber 46 thereby lifting the reciprocal cylinder 22 and its attached seat member 38 and the person resting thereon.
  • the arm portions 39 engage the ends of the rod 18, the upward movement will be stopped and the seat may be swiveled outward over the tub rim and the patient thereon may be removed or may move himself off the seat member.
