A valuable addition to any shop medicine cabinet is the tourniquet. A device that will answer the purpose of the tourniquet can be made from an ordinary clothespin and a piece of binding tape, about 3/4 in. wide and 14 in. long. To stop the bleeding from a wound on a limb, pass the tape around the injured member between the wound and the blood supply. Pass the tape through the slot in the pin, wind the ends around the pin two or three times to prevent slipping, then turn the pin to draw up the tape tightly until the flow of blood is stopped.
Mechanical Aid to Singers
Procure a large cigar box, of the square variety, and three ordinary drinking glasses with very thin walls and of different sizes, and place them in the box, as follows: Space them evenly, and drive three brads close to the circumference of each glass bottom, so that the glasses will have to be forced in between them. To prevent the glasses from touching the wood place a one-cent piece under each one.
A fourth glass is used, but from this the bottom must be removed. This can be done by saturating a string, or piece of yarn, in kerosene oil, wrapping it once around the glass near the bottom, then lighting it and allowing the string to burn out. The glass is then quickly dropped into cold water, which will remove the bottom.
A hole is cut in the cover of the box to receive the bottomless glass from the upper side, so that its lower edge will be flush with the under surface. Cut a slot, 3 in. long and 1/8 in. wide, in the cover near the back side.
To use, close the cover and at a distance of about 1/2 in. from the glass in the cover, or mouthpiece, sing into it. The glasses will impart to the voice a peculiar tone delightful to hear.—Contributed by J. B. Murphy, Plainfield, New Jersey.
Model Boat with Aerial Propeller
Procure or make a small model boat, 12 or 18 in. long, and place in the hold one or two cells of dry battery. Make a small platform in the stern and mount on it a small battery motor with the shaft parallel with the length of the boat and in the center. Directly above and parallel with the motor shaft run a shaft—a hatpin will do—in bearings fastened to the deck. Attach a drive pulley directly over the pulley on the motor and belt it up with a cord or rubber band. Purchase or make a propeller blade and attach it to the rear end of the shaft. A switch can be located on the deck for controlling the motor.—Contributed by Geo. B. Riker, Ft. Wayne, Ind.
