The connecting link between the front and rear axle is made up of five pieces of ash which 

 furnishes the spring to ease the rider. Driving attachments are fastened to these pieces 



Then fasten the ends to a cross-piece on 

 the slats, spreading them out at the 

 bottom like the shape of an inverted V. 

 The steering wheel can be made, if de- 

 sired, or it can be purchased. A wheel 

 may be obtained such as is used in the 

 place of handlebars on a bicycle. This 

 is fastened to the end of the post. 



The steering is accomplished by an ar- 

 rangement of five pulleys of the drum- 

 cable variety. Four 2-in. pulleys are 

 placed under the frame; two on a ;^8-iri- 

 rod placed directly under the steering 

 post, and at the same angle as the post 

 over which the cable passes. The other 

 two are placed, one on each side of the 

 frame, outside of the slats. One of them 

 should line with the pulley next to the 

 post block and the other with its mate. 

 The drum la'ge pulley should be 3 in. 

 long and 3 in. in diameter, and it should 



be placed close to the top of the block on 

 top of the frame. It is fastened to the 

 steering post with a long wood screw, 

 which goes through a hole bored through 

 the center of the pulley, and a similar hole 

 drilled through the post. The hole in the 

 post should be a sliding fit for the screw 

 and the hole in the pulley should be a 

 tight fit. Fasten a 6-ft. length of wire 

 to one side of the front axle. Pass it 

 around the pulley under the frame to a 

 pulley on the shaft under the post and 

 then to the drum on the post. Wind four 

 turns around the drum, and run the end 

 down under the other pulley on the shaft. 

 Then pass it around the outside pulley and 

 fasten to the other end of the a.xle. 



The lamp was made from a large oil 

 can. The spout was removed and the 

 hole reamed out to receive the screw end 

 of a 12-candle-povver electric globe. The
