What One Gallon of Gasoline 

 Might Be Made to Do 



THE power of gasoline is generally rated 

 by the distance it will propel an auto- 

 mobile. But the same energy, if directed 

 to other and more varied purposes, will 

 milk three hundred cows, bale four tons of 

 hay, mix thirty-five cubic yards of cement, 

 plow three-fifths of an acre of ground, or it 

 will generate enough electricity to light a 

 large farmhouse for thirty hours. 



"Sweeping" out a joint of plumbing 

 with the new flexible wire device 



A Pipe- Cleaning Wire Which Worms 

 Its Way Around Bends 



TROUBLE with drain pipes which 

 continually clog up can very easily 

 be done away with by the use of a steel 

 cable devised by Jay H. Woolhiser, a 

 plumber of Elmhurst, Long Island. 



Unlike the straight steel cables which 

 cannot be pushed around a sharp bend, his 

 wire can wind around the worst of them, 

 cleaning out the waste while doing 

 so. The wire is made of thin, but 

 very elastic steel. This is wound 

 around in small loops placed very 

 close together. 



The end of the wire is slightly 

 bent, and this end is slanted away 

 from the direction of the pipe 

 bend. When the wire reaches 

 the bend it therefore catches. 

 The wire is pressed down into the 

 pipe a little further, and is then 

 suddenly turned. The wire end is 

 at once released and the wire 

 springs up into the bend. 



When the waste which is clog- 

 ging the pipe is reached, the wire 

 is kept turning. The bend of the 

 wire keeps the end swinging around 

 in a circle. It thus wipes around 

 the whole interior of the pipe. 



How to Take a Drink and Eat While 

 You Are Fishing 



THE fisherman need not lose any time, 

 from his sport in order to eat, but 

 may have his hands free for attending 

 to his needs if he is equipped with the 

 new fishing harness invented by Kenton 

 Drinkard, Beaumont, Texas. This harness 

 supports the fishing pole in the proper 

 position for the line to make a catch, 

 and the fisherman need "not hold his arms 

 in one position until they are cramped and 

 aching while he is waiting for a fish to 

 find his bait. 



The device includes a body belt having a 

 socket which receives the butt of the fishing 

 pole. A second socket on the belt supports 

 a bracket arm which extends part way 

 out under the pole and in turn provides a 

 support or rest for it. A body strap and 

 chain attached to this brace, affords all the 

 additional support necessary. Equipped 

 with this device the fisherman may en- 

 joy his fishing interruptedly. 



A belt fastened around the body is provided with a 

 socket into which the pole fits, leaving the hands free
