The accompanying cut shows something new in the line of a foot-power sterile soap machine for use in operating rooms.

It consists of a cylinder and plunger, operated by foot power, applied to a ratchet wheel acting upon the arm of the piston by a double-thread screw, which forces the plunger into the cylinder. There are two blank screw caps that go with each cylinder. The plunger, cylinder and contents are sterilized before using.

The machine is taken from the bracket and the plunger removed from the cylinder; then the cylinder is filled with green soap and the blank caps are screwed on either end. The filled cylinder and plunger are then sterilized. After sterilizing the blank caps are taken off, the plunger is adjusted and the machine is placed in the bracket ready to operate.

The machine is made in three sizes, each containing ½, 1 or 2 pounds
