A Practical Electric Vacuum Cleaner 



II. — The construction of the motor was explained 

 last month. Now comes the housing problem 



By L. E. Swindell 



THE shoe is constructed of black sheet 

 iron 1/16 in. thick. The necessary 

 dimensions are given in Fig. 10. The 

 patterns should first be cut out of cardboard 

 and then traced on the sheet iron to obtain 

 the best results. The parts are cut out with 

 a pair of tinner's snips. They are then as- 

 sembled as in Fig. II. A little study will 

 show how they fit together. The holes 

 shown indicate where the parts are riveted 

 together. After riveting, all the joints are 



soldered to add to the rigidity and make the 

 fan-case airtight. Where the edges of the 

 shoe touch the floor, U-shaped pieces of 

 thin iron are used to enclose them. These 

 are soldered in place. If desired, a rotary 

 brush may be placed inside the shoe, which 

 will materially aid in picking up lint, 

 thread, etc., from the floor. On each side 

 of the fan-case is a projecting piece of 

 ^j-in. iron rod % in. long, which fits into 

 a hole in the lower end of the handle.
