THE WORLD'S ADVANCE 



A MANGLER WITH A SAFETY 

 GUARD 



One of the most dangerous features of 

 a laundry is the mangling machine, which 

 is used for pressing flat pieces. The 

 mangier consists of two iron rollers, 

 heated from the inside. The danger 

 arises in the fact that the laundry worker, 

 in feeding towels, napkins and other flat 

 pieces between the rollers, becomes care- 

 less, and the fingers, or sleeves are drawn 

 into the rolls and a serious accident 

 results. 



Among the various new appliances to 

 be given a trial in the "safety first" move- 

 ment of Cincinnati's new $4,000,000 

 hospital is a mangier in which safety is 

 obtained for the laundry worker in the 

 form of a little steel fence running along 

 the entire length of the big roller. This 

 arrangement effectively prevents fingers 

 or sleeves from being accidentally drawn 

 into the machine. All laundry machines 

 in the new hospital are carefully screened 



and cog wheels guarded so that the possi- 

 bilities of accident are minimized. Near- 

 ly $30,000 was spent by the city of Cin- 

 cinnati to safeguard this laundry. 



STEEL REINFORCING IN CON- 

 CRETE 



Steel is always to be preferred to wood 

 for reinforcing concrete, as both steel 

 and concrete adhere together satisfactor- 

 ily. Steel has also the advantage over 

 wood in that it does not swell or shrink 

 under the influence of moisture. It is 

 also known that the safe working stress 

 in long lea'f yellow pine is about 1,200 

 pounds per square inch, while the safe 

 working stress for mild steel is 1,600 

 pounds per square inch. 



While wood is claimed to be quite sat- 

 isfactory by some who use it for this 

 purpose, there is considerable contro- 

 versy in this matter. It would seem that 

 for big concrete work the steel reinforc- 

 ing should unquestionably be used. 



A Little Steel Fence Along the Entire Length of the Roller Prevents the Worker's Fingers from 

 Being Caught in the Mangle or Ironing Machine.
