�THE necessary power to drive small machin- ery in the repair shop may be obtained by the use of a wind- motor as shown. Such a motor may also be used to operate pumps and electric genera- tors for charging stor- age batteries. The device is easy to con- struct and is inex- pensive, the material being obtained from any hardware store. The driving connec- tions, such as the beveled gears and hangers may be ob- tained from old, dis- carded machinery, chine will furnish piece of 13i-in. pipe will serve for the main shaft, the length depending on the position in which the motor is set in the roof; the buckets, how- ever, should be at least 4 ft. above the roof to obtain the best results. One method of transmitting the power from the motor is shown in Fig. 1. However, the builder may choose any meth- od that will bet- ter suit his pur- pose. The object of the drawings is to show the con- etruction of the motor and in-

stallation of the buckets at the proper angles, as shown in Fig. 2. The construc- tion of the cross-arms may be readily un- derstood from the il- lustration. The meth- od of fastening the buckets to the arms is shown in Fig. 3, using plates, Fig. 4, on the inside of the buckets. The pat- tern for the sheet- iron to form the buckets is shown in Fig. 5. Mark out the sheet as indicated by dotted lines and then cut it out, which will _ allow for a 3^-in. lap. Next shape the sheet as shown in Fig. 6, and punch the hole to receive j/^-in. bolts. The buckets are then bolted to the cross- arms, using the plates. Fig. 4, on the inside. The cross arms and buckets are now complete.
The bearing to receive the main shaft is made of a piece of pipe 3 in. in diameter with both ends threaded to re- ceive ordinary pipe caps. Drill holes 1^ in. in the cen- ter of the caps, to receive the shaft. The com- pleted bearing is fastened to one of the rafters as shown in Fig. 1. The shaft is run
