84 GOODYEAR ON GUM-ELASTIC. 



IMPROVED PORTABLE PRESERVING APPARATUS. 



The principal, if not the only objection which appears to 

 exist to the invention before described, is the difficulty attending 

 the re-shipment of packages. This has, however, led to an im- 

 provement upon this invention, which removes this objection. 



When this apparatus is made for transporting articles that 

 are not liable to be injured by pressure, the gum-elastic case is 

 simply a bag of caoutchouc fabrics, in two halves, the edges of 

 which are made of an elastic fabric. These bags are drawn 

 over and secured upon an iron or other metal band, as repre- 

 sented, plate , fig. 



When fruit or other articles which are liable to injury by 

 pressure, are to be preserved, and shipped or transported, these 

 bags are distended by a jointed metal or wooden frame, as rep- 

 resented, plate , fig. . By this arrangement there is no loss 

 of packages, as in the case of preserving articles in tin boxes. 

 In all cases the air is exhausted from these bags and receivers 

 with the force-pump, through a hose which is attached for this 

 purpose. The frame packed with the bags occupies httle space. 



STEELYARDS AND SCALES. 



The application of vulcanized gum-elastic to steelyards and 

 scales, particularly hay scales, is the invention of another. The 

 manufacture has not been established, but from the well-known 

 properties of this substance, there is little reason to doubt that 

 there will be economy and advantage derived from this applica- 

 tion to large scales. 



BAKERS' BELTING. 



At a very early period, and soon after the discovery of the 

 vulcanizing process, gum-elastic was successfully applied to the
