Abstract: 584,583. Refrigerating. MATTISON, F. W., and TURNER, H. J. Jan. 5, 1945, No. 489. [Class 29] [Also in Group XXVIII] A gravity-operated refrigerating machine comprises two cylinders 14 fixed to a horizontal shaft 10 and each containing a heavy piston 15 so that, as shown, the right-hand piston compresses refrigerant fluid and forces it through a needle valve 17 and an expansion valve 18 to an expansion coil 19 surrounding the shaft. The other piston sucks the refrigerant from the coil through a non-return valve 22. When the pistons reach the lower ends of the cylinders, which may take six hours, the shaft 10 is turned through 180‹ by a handle 25 and the action is repeated, the refrigerant flowing in the opposite direction. Springs 23 assist the descent of the piston which is compressing the fluid and cushion the descent of the piston which is sucking fluid into its cylinder. Rubber bellows 24 prevent leakage of fluid. A detent 26 retains the shaft 10 in position. The coil can be fixed and connected to the cylinders by flexible pipes. The shaft may be turned by trip gear controlled by a descending weight. An additional notch may be provided for the detent to hold the shaft in an inoperative position with the cylinders horizontal.
