Stripped of His Clothes by a 

 Projecting Cutter 



THE collection of clo- 

 thing shown in the 

 picture is interesting 

 only as an illustration of 

 how close a careless work- 

 man can come to a serious 

 accident and yet get off 

 practically unscathed. 

 The man in question was 

 cutting an elongated hole 

 in a die block with a cut- 

 ter projecting about 

 three- sixteenths of an 

 inch. 



While the drill press 

 was in motion, the elbow 

 of the workman, who was 

 leaning on his work, came 

 in contact with the cutter. 

 The cutter caught his 

 sweater and stripped him 

 of practically his entire 

 clothing, consisting of 

 sweater coat, street coat, 

 overalls, vest, shirt and 

 undershirt. 



The beneficent Provi- 

 dence that watches over 

 even the criminally care- 

 less saw to it that he 

 escaped with only a dis- 

 located shoulder.

Saving Coal by Feeding a Fire 

 with Hot Air 



OUR fuel bills are high 

 because we get so 

 little heat from the coal 

 we burn. If we could 

 take out of a piece of 

 coal all the heat that 

 Nature has stored up 

 in it for us, our coal 

 bills wouldn't bother 

 us. As it is, we waste 

 most of the coal we 

 burn. Half the heat 

 goes up the chimney 

 and most of the gases 

 arising from a hot bed 

 of coals will not burn 

 because the fire isn't hot enough to make 

 them combustible. 



To eliminate this unnecessary waste 

 Charles W. Huse, of Gary, Indiana, has 

 invented an air-feed, or auxiliary draft. 



wTiich Introduces heated air Into the firebox, 

 thus giving a perfect mixture of all the 

 gases and forcing the 

 flames to all parts of the 

 firebox. The air Is ad- 

 mitted through an air- 

 Intake equipped with 

 handles and a regulating 

 shutter. It Is taken to 

 the firebox through a 

 tube. A nozzle on the 

 inner end of the tube 

 distributes the heated air 

 over the flames. 



When the furnace Is 

 being fired the door as 

 well as the tube is swung 

 around to one side out of 

 the way; or the tube can 

 be raised, lowered, or 

 turned in any directon. 

 Thus, in banking a fire 

 for the night, the nozzle 

 of the tube is turned up- 

 ward by means of the 

 handle, allowing the heat- 

 ed air to pass through the 

 flues of the boiler or 

 furnace. 



The nozzle is made of 

 a specially prepared metal 

 which will stand excessive 

 heat even when the air is 

 not passing through It. 

 The heat supplied by 

 the furnace after the In- 

 device is greatly in ex- 



stallation of the 



cess of the amount given out be- 

 fore, even though only one-half 

 the usual quantity of coal 

 be used. The saving, there- 

 fore, is obvious. 



The air-feed, 

 or auxiliary 

 draft, which 

 introduces

The tube as well as the door may be swung 

 around out of the way, or it may be raised, 

 lowered, or turned in any desired direction
