Grading Machine Does Work of 125 Men 



It digs to grade and loads six 

 hundred wagon loads in a day 



This machine reduces road grading and the construction of good roads to 

 an economical and scientific basis. It does the work of a large road-gang 



NOT SO long ago a huge machine 

 made its appearance on a Milwau- 

 kee street which had to be graded. 

 The machine had creeper feet in front that 

 reminded one of the tread of a tank on the 

 Western Front, and in the rear a roller. 

 There was a huge wheel on its front which 

 tore up the dirt precisely to the depth 

 wanted — no more and no less — with the 

 relentlessness that never could be equalled 

 by hand shovels. 



If you want to know more about the 

 Turbine Street and Highway Grader, look 

 at the accompanying picture. The dig- 

 ging is done by a rotating cylinder on 

 which are mounted twelve buckets. 

 Rooters on the cutting edge of the buckets 

 lift up the dirt and tumble it back into 

 the buckets. As the cylinder turns, the 

 dirt is dumped on a belt-conveyor, which 

 extends at right angles from the side of 

 the grader and drops the material into a 

 waiting wagon, truck or car. 



Almost everything about the machine is 

 adjustable to suit the conditions en- 

 countered. Thus the conveyor can be ad- 



justed to load on either side of the grader. 

 The cutting cylinder or wheel can be ad- 

 justed vertically to make it cut from one 

 inch to two feet deep. Cuts are five feet, 

 seven inches wide. While the digging 

 wheel is in action, the entire machine 

 moves forward at any of three speeds ac- 

 cording to depth of cut and character of 

 material which is being excavated. 



The creeper tread on which the front 

 part of the grader is supported does away 

 with planking and prevents settling. But 

 if settling should occur, it is easily enough 

 detected by sighting along the grade 

 sticks and corrected by elevating the cut- 

 ting cylinder or turbine. The two sets 

 of creeper treads have separate controls 

 which makes it possible to make short 

 turns when necessary. 



When it is realized that the utmost 

 capacity of hand-shovel labor is five 

 wagons a day and that the Turbine 

 Grader can easily load six hundred wagons 

 and even more a day, the possibilities of 

 the machine become apparent. It does the 

 work of 125 men at a great saving of cost.
