Sleep in Hot Water to Rest 

 Your Nerves 



SLEEPING in a bathtub full of wa- 

 ter kept at blood temperature is 

 claimed by some physicians to give the 

 required amount of rest in half the time 

 that sleeping in bed requires. In other 

 words, four hours sleep in a bathtul) 

 filled with water at the proper tempera- 

 ture — and always maintained at that 

 temperature — will result in the exact 

 amount of restfulness that eight hours 

 in bed will give. 



The explanation is that warm water 

 completely relaxes the nerves, which or- 

 dinary sleep does not necessarily do. The 

 most difficult part of this treatment is in 

 maintaining the water at a constant tem- 

 perature, and for the purpose of accom- 

 plishing the result, a middle-western 

 manufacturer has recently brought out 

 on the market a thermostatic water con- 

 trol apparatus, which, as its name im- 

 plies, maintains the water at any desired 

 temperature. 



In practice, the patient climbs into a 

 bathtub filled with water, his head pro- 

 truding through a hole in a rubber blan- 

 ket, which is strapped around the edges 

 of the tub. Water constantly flows in 

 at one end of the tul), and out at the 

 other. 



For the harried business man. who 

 complains that his working day is too 

 short, such a sleeping couch as this 

 should have a distinct appeal. He should 

 be willing to rest four hours at least. 



Here is a system of heat regulation that 



makes it possible to sleep in a bath that 



is always at the same temperature 



With this invention, telephone, line work 



is as comfortable as sitting or standing in 



the shop would be 



A Machine Which Climbs Poles 



A POLE or stack-climbing appara- 

 tus in which the pole or stack 

 climber sits comfortably wdiile elevating 

 or lowering his position, as the work 

 progresses, by a simple arrangement of 

 clutches, has been constructed and put 

 in use by a young telephone lineman in 

 Arizona. The climber (the machine, not 

 the man) consists of two parts, an upper 

 and a lower. The mechanism in the up- 

 l)er part contains clutches which grasp 

 the pole firmly, being manipulated by 

 ropes from the seat below. 



To climb the pole, the lineman or 

 stack-climber takes his seat as far above 

 the ground as possible in order to ex- 

 pedite matters. The clutch mechanism 

 is pushed upwards as far as he can 

 reach ])y means of a wooden pole. The 

 clutch is then set, and with a rope and 

 ])ulley arrangement, he elevates the seat. 

 V,y continually repeating this operation, 

 I)ushing the clutch box upwards as he 

 progresses, he literally crawls to the top 

 of the pole or stack.
