THE WORLD'S ADVANCE 



at hand, for all the threading can be 

 done better in the enginee lathe. 



The workshop should preferably be 

 spacious; a barn or carriage house is 

 excellent. It is very likely, however, 

 that the place to be used for the final 

 housing of the car will have to answer 

 the purpose. While the author may be 

 accused of using chestnuts, still, it seems 

 advisable to repeat the time-worn story 

 of the chap who built his boat in the 

 cellar and then had to tear out the side 

 of the house in order to get his handi- 

 work to the water. The moral of this, 

 as applied to our workman, is not so 

 much that he could not get the car out 

 of the cellar, but why build it there 

 when he would only have to provide a 

 place subsequently for its storage? If it 

 is necessary to build a garage of some 

 sort, far better it is to build the house 

 before starting the car. 



Constructional Features 



A brief inspection of the drawings will 

 disclose the fact that this is essentially a 

 car without springs. The construction 

 is so simplified through the elimination 

 of the conventional spring that the loss 

 of this important member is believed to 

 be justified. At the same time, if the 

 complications arising through the intro- 



duction of semi-elliptic springs, particu- 

 larly at the steering gear, can be tolerat- 

 ed, the builder is by all means advised 

 to insert them. As it appears in the 

 drawings, however, the car has certain 

 spring qualities inherent in its construc- 

 tion. The members which support the 

 weight of passenger, body and engine, 

 are struts of ash and obviously they 

 form springs in themselves. The body 

 and hood of the car stiffen the struts to 

 such an extent that they bend only at 

 points near the center. 



The wheels are of the standard motor- 

 cycle type or even substantial bicycle 

 wheels, if the latter are the more readily 

 obtained. Steering is accomplished 

 through the usual knuckle arrangement, 

 which has many advantages over the 

 method in which the entire front axle 

 turns. The drive to the rear wheels is 

 by means of belts which are arranged in 

 such a manner that they may be tight- 

 ened through the agency of idlers con- 

 trolled by a convenient lever. Braking 

 is accomplished by tightening a piece of 

 steel cable around a pulley affixed to the 

 hub of each of the rear wheels, the 

 brakes being applied by a foot pedal. 



The differential gear was omitted 

 owing to its complexity and not through 

 lack of recognition of its great impor- 

 tance. The narrow tread of our car,
