the tube F around and stick it through the keyhole. Few burglars

** A Homemade Water Motor [66]
By MRS. PAUL S. WINTER

with a washing machine, and the question that arises in the mind
of the householder is how to furnish the power to run it
economically. I referred this question to my husband, with the
result that he built a motor which proved so very satisfactory
that I prevailed upon him to give the readers of Amateur Mechanics
a description of it, hoping it may solve the same question for

A motor of this type will develop about 1/2 hp. with a water

smaller pulley. Fig. 1 is the motor with one side removed, showing
the paddle-wheel in position; Fig. 2 is an end view; Fig.
