 Distilling Water for the Household 



FOR the housewife who wishes to 

 be sure that her family is drinking 

 perfectly pure water, the new home 

 water still is most important. It is made 



of copper and lined 



throughout with tin, 



as this metal is un- 

 changed by distilled 



water. The device 



consists of three 



drums, one upon the 



other. The bottom 

 .iTrone is the boiler, the 



middle one is the 



reservoir for the dis- 

 tilled water, and the 



upper one is the 



condensing chamber 

 above which cold water is placed to 

 cause the steam which rises from the 

 boiler to condense. 



To obtain distilled water, the boiler 

 and cold water chamber are filled and 

 the still placed on the stove. The dis- 

 tilled water falls into the reservo'r (mid- 

 dle drum) through a water seal (L). 

 This seal is an important improvement 

 over the ordinary still because it confines 

 the steam from the boiler, thus increas- 

 ing the pressure in the condensing cham- 

 ber and giving twenty-five per cent more 

 condensation with the same amount of 

 heat. The distilled water may be drawn 

 ofif at any time through a faucet, and 

 the water in the cooling chamber al- 

 lowed to flow from a faucet into the fill- 

 ing aperture of the boiler to replenish Serving Table Attached to Range

hole in the rod and as the crank is turned 

 the wire will be wound on the rod in an 

 even layer. Each piece of wire gives a 

 coil, closely wound, 4" long. Remove the 

 end of the wire from the hole and the 

 coil will slip off the rod. When the coils 

 are stretched over a frame of wood so 

 that they are 6" long the adjacent turns 

 of the coil will no longer touch. In this 

 way one can wind 120 coils in one after- 

 noon. 



A Home-made Paper Baler 



HOW to dis- 

 p o se of 

 waste paper is a 

 problem that is 

 often presented 

 to the city dwel- 

 ler. The accom- 

 panying sketch 



shows how accumulated paper may be 

 baled in a simple apparatus. Use 

 a strong wooden box about 22"x28"x30", 

 and strengthen the corners with angle 

 irons. Saw the ends apart diagonally, 

 and by means of two step hinges join 

 the two halves together. 



Two baling wires should be hung 

 from the inside of the box. Paper 

 placed in this box can be pressed down 

 until a bale weighing from 40 to 50 lbs. 

 is produced.- After the bale is wired, it 

 can be easily removed and taken away 

 by the junk man. 



Making an Electric Toaster 



MANY experimenters wish to make 

 resistances for electric toasters and 

 heaters but are at a loss to know how to 

 wind the resistance coils for it. The fol- 

 lowing method of winding the coils of 

 wire will be found practicable. The wire 

 used should be about No. 22 (B. & S.) 

 iron wire, such as is used in basket mak- 

 ing. Remove the handle from a hand 

 drill and fasten the drill in a vise so that 

 the crank can be revolved freely. Put a 

 3/16" rod, 5" long with a 1/16" hole 

 through one end in the chuck. Cut the 

 wire into about 10' lengths and put one 

 end of a piece of the wire through the

 table that 

 can be attached 

 to the range will 

 save much time 

 for the housewife 

 in the kitchen. 

 Referring to the 

 drawing, the 

 board is attached 

 to the stove by 

 means of braces and rivets. 



To the right of the shelf is the hot 

 water boiler. A faucet may be installed 

 in the boiler above the shelf. 



Well seasoned wood should be used, 

 and covered entirely Avith a layer of 

 sheet copper.
