A Fuel Economizer 



A CONSIDERABLE portion of the 

 heat from the ordinary home fur- 

 nace escapes, by way of the flue-pipe 

 "and chimney, into the open air. Conse- 

 quently, if this wasted heat could be 

 diverted into the rooms of the house, 

 less coal would be required ; and more 

 heat could be pro- 

 duced from the coal 

 used. The device 

 shown in the illustra- 

 tion, which should be 

 installed with the 

 heating system, con- 

 sists essentially of 

 two pipes of sheet 

 metal, one enclosed 

 within the other. The 

 inner pipe is the flue ; 

 and the outer enclos- 

 ing pipe, which 

 should be 4'' or 5" 

 wjjf\j larger in diameter 

 than the inner pipe, 

 carries the air from 

 the cellar up along 

 the hot flue pipe. The 

 air enters the outer 

 pipe by way of the opening at A; and as 

 the air rises, it absorbs the heat from the 

 flue. Directly above the floor on each 

 story, a register is installed in this outer 

 pipe; and the hot air, which is ordinari- 

 ly wasted, is thus used to heat the rooms. 

 The outer pipe should be led into the 

 attic, where it terminates, and a ring 

 should be placed over its open end to 

 prevent the entrance of dust and par- 

 ticles of wood into the device. The in- 

 ner pipe, of course, enters the chimney 

 in the usual way. To increase the ef- 

 ficiency of the outer pipe, it is advisable 

 to cover it with a layer of asbestos, 

 which insures the escape of the heat 

 only at the registers on each floor. 



Helping to Kindle Fire Wood 



SMALL kindUng can be fired quickly 

 if the wood is dipped in a hot solution 

 of two quarts of tar and six pounds of 

 resin. When this is cool, fine sawdust 

 and powdered charcoal should be added 

 until a thick consistency is obtained. 

 This mixture should be spread in a layer 

 one inch thick over the kindling wood.

 A Remedy for Sagging Doors 



THE ten- 

 dency o f 

 heavy swinging 

 garage or barn 

 doors to sag can 

 be rectified by 

 proper bracing. 

 Two i^"" iron 

 rods are fitted 

 diagonally in-' 

 side the doors 

 from the lower 

 outer corner to the hinge in each upper 

 corner. Tlie rods are bent in the shape 

 of an eye at one end and threaded at 

 the other. The eye is bolted to the 

 hinge while the threaded end is passed 

 through the flange of an L-shaped iron 

 cleat held down by a lug. A nut which 

 holds the rod in the cleat serves as a 

 turnbuckle for raising the door to its 

 original position. 



Pouring from Lipless Jars 



LIQUIDS are 

 likely to be 

 spilled when 

 pouring from a 

 vessel that has 

 no lip. If a glass 

 rod is held 

 against the rim 

 it conducts the 

 liquid where it 

 is required and 

 with care not a 

 drop need be 

 lost. 



Waste Heat Warm.s Water 



THE wasted 

 heat from a 

 small gas heater 

 can be put to 

 work, warming 

 water for house- 

 h o 1 d use. A 

 small stove pipe 

 should be led 

 from the top of 

 the heater and underneath a hot water 

 tank placed in a horizontal position. A 

 section of eaves trough to cover the pipe 

 in its contact with the tank will save 

 much heat.
