draining table (figure 3), any 

 undesirable portions were 

 picked out and discarded. 

 Four men were necessary for 

 the operation. One man con- 

 trolled the flow and raked 

 the viscera down the sloped 

 table (sloped approximately 

 6 inches in 8 feet) to the 

 second man (figure 4)» viho 

 sacked the drained material 

 (figure 5). The filled sack 

 was passed to the third man, 

 vrtio knotted the top of the 

 polyethylene bag and wire- 

 tied the outside burlap bag 

 (figure 5). The secured 

 sack was then placed on the 

 elevator (figure 6). The 

 fourth man hand-winched the 

 loaded elevator (six sacks) 

 up to dock level, removed 

 the sacks, and returned the 

 elevator to the platform. 

 The fourth man also made up 



15 feet long, from the 

 surface of the dock to

By means of shields 

 (figures 1 and 2) install- 

 ed at the rear of the Iron 

 Chinks, the viscera were 

 diverted through a grate 

 in the floor of the can- 

 nery into a wooden chute 

 (10 by 10 inches by 60 feet) 

 installed underneath the 

 cannery floor. The viscera 

 were carried down the chute 

 by water from the sprays on 

 the chinks onto the drain- 

 ing table. A series of 

 trap doors installed in the 

 chute was used to control 

 the rate of flow. As the 

 viscera from the three 

 chinks, with much excess 

 water, flowed onto the 



Figure V-3. Draining table. Viscera 

 flow onto and are raked dovm the 

 sloped table; the water falls through 

 the openings. One of the trap doors 

 to control the rate of flow is lo- 

 cated at the end of the chute (right
