TELPHERAGE.

other system that can do this so economically, cheaply, and in a way 

 so thoroughly satisfactory a manner as telpherag-e. 



The nature of installation varies with the amount of material to t)e 

 carried, so that if the amount to l)e carried is small, the expenditure 

 need not l)e great. 



Apph'caf/'ons of tclpheriKje. — There arc few factories where the 

 installation of an overhead telpherage system would not prove a valu- 

 able investment. The question is often asked: Is telpherage suited for 

 carrying specitic articles? And the reply may be that it is adapted to 

 the conveying of the products of almost every kind of manufacturing. 



Fjg. 9.— In sewer or trench excavation the method of operation is as follows: The bucket has 

 attached to it a trailer wheel. The huckets and wheel are lowered into the excavation and the 

 bucket, when filled, is raised by the electric hoist so that the wheel of the trailer engages the gravity 

 rail. The load then passes by gravity to the place desired and is automatically dumped. This may 

 be along the line of excavation, for refilling the trench, or to the right or left, for unloading into 

 carts, or in connection with the telpher to any desired distance. The telpher has the (lexibility of a 

 trolley car. This method is a comliination of telpher and gravity lines, and the amount of work that 

 can be accomplished by it with the miniumm of labor is remarkable. 



In these days of consolidation of companies, factories cover immense 

 areas. The individual buildings are frequently large enough in them- 

 selves to utilize a tel})h('r liiH\ In many cases, on account of fire risks 

 or of convenience in matuifacturing, the buildings are widely se})arated 

 from each other, and yet constant communication is necessary. Over- 

 head telpherage, therefore, in manufacturing establishments is used 

 for carrying the law material, implements, and tini.shed products from 

 one part of the gi'ounds to another, from one building to another, or 

 even from one.part of a building to another part, moving raw material 

 from cars or vessels to the works and then taking the finished i)roducts
