 �122 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 it.

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

��A SERVING 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.
