ARRANGEMENTS FOR LOADING LOGS ON WAGGONS, SLEDS, AND CARS 



The loading cable runs over a swivel loading block suspended from the tip of the boom so as to 

 hang centrally over the empty to be loaded. The two hook tenders hold the "Martin" loading hooks 

 to the faces of the logs. The pull of the cable inserts the hooks securely, and the machine either throws 

 the log, by impact and timely dropping, directly 

 into position, or else lays it to rest quietly, 

 as if it were a baby, into a secure place on 

 the car. A top loader handling a light cant- 

 hook helps in adjusting the load. When a 

 change of loading site is desired, powerful, 

 ratchet-driven chains, at the will of the en- 

 gineer, are set in motion by a clutch lever, 

 revolving the axles of the wheels as the chains 

 pass over them. In the pineries, one engineer 

 and three colored helpers load, with a McGif- 

 fert, 100,000 feet b. m. of logs per day. 



(b) Self- propelling, car-spotting log 

 LOADERS, WITH SWINGING BOOM. The Ameri- 

 can log loader (manufactured by the American 

 Hoist & Derrick Co., St. Paul, Minn.), Models 

 "D" and "E," is a self-propelling locomotive 

 crane, with swinging boom, strong enough 

 to push or pull a few loaded cars. It spots 

 its empties by swinging them, by a turn of 180 degrees of the crane, bodily from behind to the front. 

 The machine is useful also in moving and in laying track. 



(c) Non-self-propelling, non-car-spotting log LOADERS WITH SWINGING BOOM. The American 

 log loader, models "C" and "G," (manufactured by the American Hoist & Derrick Co., St. Paul, Minn.), 



The "Martin" grip hook, adapted to light as well as to heavy logs. 



American log loader, self-propelling type, spotting its own empties by swinging them from the rear to the front. 



and the Barnhart log loader (made by the Goodyear Lumber Co., Buffalo, N. Y.) belong to this class. 

 The wheels of the American travel, under its own steam, over a steel rail track laid by the machine 

 in sections directly on the bolsters of the cars to be loaded. The Barnhart requires rails permanently 

 fastened to the bolsters. The boom is a swinging boom, capable of swinging in a circle (American) or 

 in a semi -circle (Barnhart), thus picking up logs from the right or from the left rapidly by means of a 

 cable running from the Martin hooks at the log ends, over a sheave in the boom tip and then over the 

 drums of the engine. The machine leaves the empty, on which it stood when loading, after finishing the
