 The Brainless Drink-Mixer. 

 It Never Makes a Mistake 



IT is said that an efficient drink- 

 mixer is a rarity because it 

 is practically impossible for a 

 man to make two drinks, com- 

 posed of the same ingredients, 

 taste alike. But with the drink 

 mixer invented by Nicholas 

 Jacovatos, of New York city, 

 the mixing is done automatically 

 and carelessness is eliminated. 



His drink mixer resembles an 

 ordinary ice-water cooler. In the 

 interior are a number of compart- 

 ments holding different flavors 

 or liquids. The compartments 

 are filled through tubes which 

 extend to the outside, avoiding the incon- 

 venience of lifting the cover to replenish 

 the supply. One side of each compart- 

 ment rests against a chamber containing 

 ice, which keeps the contents at a con- 

 stant temperature. 



To obtain a mixed drink, 

 the operator turns a lever, 

 which causes a valve con- 

 nected with it to mesh first 

 with one compart- 

 ment and then with 

 another, until the 

 several liquids which 

 make up the desired 

 concoction have all 

 been released into 

 the glass.

HILE all the western world is 

 echoing the slogan " Do It Elec- 

 trically," and pulling down old ma- 

 chinery in order to install 

 new devices requiring fewer 

 operators, China is still 

 employing the man- 

 power tread-mi lis 

 shown in the 

 accompanying illus- 

 tration. Here men, 

 women and children 

 take turns keeping 

 the mill going and 

 thus pumping water 

 into the reservoir 

 seen at the left of

A Floating Match-Safe Made from 

 a Shaving-Stick Container 



CERTAIN brands of shaving sticks 

 come in strong metal containers 

 which may be converted into useful 

 match-safes for the camping outfit. These 

 boxes hold fifty matches, which are enough 

 for the use of one man for two weeks. 



Although the cover fits well, the match- 

 safe will not be waterproof unless a strip 

 of adhesive plaster is wound around where 

 the cover joins the box.
