When by reason of rust, corrosion, or any other agency, the shell of the kitchen boiler is punctured, the problem of stopping the leak should not cause Handy Man any worry. A little device like that shown above can readily be made, and it will effectually and permanently close the hole. It consists of a square-headed brass machine screw, with head flattened and pierced to receive a pin. whereby it is pivoted between the walls of a channelshaped brass bearing piece. The opposite end of the screw is fitted with a leather washer, a broad metal washer slightly cur to fit the contour of the boiler, and a nut.

Fig. 282 - Patch for the kitchen boiler.

The illustration shows how the device is applied. The puncture is enlarged sufficiently to admit the bearing piece. The latter is swung into alinement with the screw and passed through the hole. The overhanging part of the bearing screw should be longer, and hence heavier, than the other portion, so as to make the bearing piece swing to a vertical position as soon as it clears the inner surface of the boiler shell. The screw will then be retained by the bearing piece, and the nut can be screwed up to clamp the leather against the outer surface of the shell. This done the projecting part of the screw can be cut or filed off.
