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.
