geared locomotive, suitable wheels es- 

 pecially constructed for the purpose, 

 taking the place, on the axle, of the 

 main driving wheels. These wheels 

 are covered with an endless chain or 

 sectional metal belt which is forced 

 to revolve by the revolution of the 

 driving sprocket wheels. The greater 

 portion of the weight of the boiler 

 and locomotive rests on the revolving 

 sections of the metal belt, which are 



be turned in any desired direction by 

 the man piloting the hauler, with a 

 lever purchase wheel similar to the 

 guiding wheel on an automobile or 

 an ordinary brake wheel on a car. 



The hauler is not confined to for- 

 ward motion alone, but can be re- 

 versed as quickly as any locomotive 

 of this type, and may be guided by 

 the runnered sled into any desired po- 

 sition. That it is a practical suc-

armed with teeth or calks, these be- 

 ing set into the sections transversely. 

 The calks are driven into the ice road 

 by the weight of the machine, thus 

 giving the hauler its traction or fric- 

 tion power for starting and keep the 

 heavily loaded sleds in motion. The 

 front end of the hauling engine rests 

 on the center beam of a movable sled, 

 which is so constructed that it will 

 run forward or backward, and may

 The rate of speed which can be main- 

 tained with a load of trailers (cou- 

 pled log sleds) is from five to seven 

 miles an hour. It is confidently ex- 

 pected that this hauler will be able 

 to handle ten pairs of loaded log sleds 

 on each trip when the roads are in 

 good condition, each pair of sleds car- 

 rying 10,000 feet of logs B. M. (log 

 scale).
