The massaging is accomplished by the alternat- 

 ing inflation and deflation of the attached tubes 



A Machine that Massages Your Pains 

 Away with Air 



AN air-operated massage apparatus 

 with action somewhat like a milking 

 machine has been devised by Frank and 

 Wilfred Shurtleff, Moline, 111. Elastic 

 tubes are attached to the inner portion of a 

 broad belt, and into these, flexible air-pipes 

 are led. Air is pumped through these pipes 

 by a pump driven by an electric motor. 

 As the tubes are alternately inflated and 

 deflated, they perform a constantly shifting 



or massaging action without discomfort to 

 the patient. The two pump-cylinders are con- 

 nected by a bypass with a valve to regulate 

 the pressure of air in the massaging tubes. 

 Belts of different sizes may be readily at- 

 tached to the apparatus, making it adapt- 

 able to a variety of treatments. 



Sleeping on a Mattress Filled 

 with Water 



ONE of the things needed by physi- 

 cians is a bed that can be heated or 

 cooled according to the needs of the 

 I)atient, and one that a patient can lie 

 upon for months, if necessary, without 

 getting bed sores. An inventor has filled 

 this want with what he calls a water bed. 

 The bottom and sides of the bed are' 

 built of galvanized steel, and the top is 

 made of rubbered canvas. When this is 

 filled with water it makes as soft a mat- 

 tress as any one could desire. A reser- 

 voir is stationed at the head of the bed, 

 which holds enough water to make the 

 pressure in the mattress the same at all 

 points. ' 



TKe reservoir will hold one hundred 

 pounds of ice for keeping the bed cool and 

 comfortable for typhoid fever patients or 

 for anyone in the summer time. 



Under the foot of the bed is an oil stove 

 which has a flue that runs under the center 

 of the bed to the head. This artificial heat 

 would be useful in case of a patient who was 

 suffering from surgical shock, hemorrhage, 

 chill or collapse. A thermometer is attached.

The temperature of the 

 water is kept under con- 

 stant control. Ice water is 

 used for fever patients 

 and heated water for suf- 

 ferers from shock or chill
