Giving Fords a Greater Pulling 

 Power for Heavy Loads 



ALTHOUGH in passenger car service 

 the Ford car generally has adequate 

 pulling power for all kinds of hills, there 

 are times when it is used as a delivery- 

 truck that still greater power at low 

 speeds would be advantageous. 



This device is inserted in the regular 

 Ford driving shaft just forward of the 

 rear axle and con- 

 sists of a small case 

 enclosing a series of 

 gears which are al- 

 ways in mesh. This 

 constant-mesh fea- 

 ture distinguishes 

 the invention from 

 the gears of the 

 average passenger 



car in which each gear is out of mesh 

 except when transmitting power. In the 

 device illustrated the gears, while always 

 in mesh and turning, transmit the power 

 only when they are locked to the shaft by 

 means of jaw clutches. These can be 

 slid into mesh with much less chance of 

 stripping than the gears themselves. 



The Ford car is operated as usual, 

 except when additional gear driving 

 ratios are required. Then the auxiliary 

 gearset control is operated to give three 

 additional ratios, one in low, one in 

 reverse and the third in intermediate 

 speed, thus giving the engine almost 

 double the flexibility. 



This auxiliary gearset gives a Ford more 

 reserve power on hills or with heavy loads 



The Motion-Picture Scene-Shifter 

 Enters the War 



POOR Fritz will never again believe 

 what he sees, or believe what he 

 thinks he sees. "When is a tree not a 

 tree," is going to become a more terrifying 

 conundrum to him every day. This is the 

 reason why: — Moving picture men are 

 going into the "camouflage" business. 

 Some of the recruits of a newly or- 

 ganized United 

 States Army corps 

 are experienced 

 motion picture men. 

 A full company has 

 been raised in the 

 Los Angeles studios 

 alone. Another 

 company stands 

 ready to be enrolled. 

 The men are eager to use their skill to 

 "make up" imitation cannons, tanks, ma- 

 chine guns and other grim actors for their 

 parts at the Front. 



A recent demonstration, held in one of 

 the great Los Angeles studios, revealed 

 the possibilities of "camouflage." The 

 wizards of illusion raised a village in the 

 twinkling of an eye; tore it down with 

 equal dexterity, and in an incredibly 

 short time substituted a startlingly perfect 

 "camouflage" forest. The fairy-tales of 

 our youth, in which genii and fairies raised 

 and removed castles by magic, seem to 

 bid fair to come true in these days of 

 seeming miracles. 



Two masterpieces in camouflage. The first is a sham "gun. " In the second, village, gun, 

 smoke, and all, are, for practical purposes, "of the stuff that dreams are made of"
