These Are the Trapeze Artists 

 Among Telephone Poles 



TELEPHONIC com- 

 munication has be- 

 come so much a part of 

 our everyday life that 

 the new camps springing 

 up number telephones as 

 among the first military 

 necessities. 



In equipping Camp 

 Gordon, near Atlanta, 

 Ga., the telephone wires 

 had to be swung across a 

 long, newly made rail- 

 road cut. Speed was 

 imperative. Instead of 

 making a detour, pole- 

 less, aerial cross-bars 

 were placed in position, 

 held secure by guy wires 

 fastened to poles run- 

 ning at right angles to 

 them. 



Four hundred tele- 

 phones will be installed. 

 The plant needed to con- 

 nect these telephones 

 with the exchange is 

 large enough to do credit 

 to a fair-sized town. 



is cut out to conform to the shape of the 

 top of the coat displayed and of the be- 

 holder's chin. Thus the man looking in 

 the window sees himself 

 wearing the suit on dis- 

 play. 



Crossbars held in position by 

 wires attached to poles at the

How Would I Look in That Suit?

PERHAPS you

 how you v.'ould '♦■■^♦^ 

 look if you were wearing 

 it. Charles H. Mac- 

 Questen, of Bloomfield, 

 New Jersey, has devised 

 the means of gratifying 

 your curiosity. His de- 

 vice consists of a support 

 for a suit which is dis- 

 played in a show window 

 at a height which would 

 correspond with the 

 height of the average 

 man. Behind the clothes 

 he has placed a mirror

Steel Wheels Are Be- 

 coming Popular 



THE tendency to sub- 

 stitute steel for 

 wood in the manufac- 

 ture of wheels for auto- 

 mobiles and heavy 

 trucks is not due to any 

 desire to economize in 

 the cost of the wheels, 

 but is largely the result 

 of the scarcity of good 

 wood. In Europe, the 

 wooden wheel has long 

 been replaced by the 

 steel wheel on trucks. 



The most widely used 

 wheel in England today 

 is made from sheet steel. 

 It is stamped in two 

 parts. These are after- 

 ward welded together by 

 an acetylene flame. 

 The finished wheel looks 

 almost exactly like a

From three to 

 six bolts are used, 

 according to the 

 size of the wheel. 

 These have cap nuts. 

 The outer nave plate is 

 a loose fit on the hub, so 

 that the wheel can be 

 pulled off easily when 

 the nuts are removed. 

 The wheel can be sup- 

 plied with a demount- 

 able rim if desired, but 

 there is very slight de- 

 mand for such rims in 

 England.
