In erecting the Municipal Bridge over the Mississippi River at St. Louis, sand boxes were 

 used for camber blocking in the place of the usual timber camber blocking. 



The threads of pins should be protected by pilot nuts and pilot points when driving. Details 

 of standard pilot nuts are given in Table 99, Part II, and of standard pilotpoints in Table 100, 

 Part II. 



RIVETING. Field rivets may be driven by hand or with pneumatic riveters. Before 

 driving the rivets the parts to be riveted must be drawn up by means of erection bolts so that the 

 holes are fully matched and the surfaces of the metal are so close together that the metal from the 

 rivet will not flow out between the plates. The holes are brought in line and matched by the use 

 of drift pins, Fig. 7 and Fig. 17; care should be used not to injure the metal with the drift pin. 

 If the holes will not match they should be reamed. A gang for hand riveting consists of four 

 men, (i) a rivet heater, (2) a bucker-up, (3) a rivet driver, and (4) a man to catch and enter the 

 rivets, to assist in driving and to hold the rivet set (snap). The hot rivet is thrown by the rivet 

 heater with rivet-pitching tongs, Fig. 1 1 ; the rivet is caught in a bucket or keg and is put into the 

 rivet hole with the rivet-sticking tongs, Fig. II. The rivet is then bucked-up with a dolly, Fig. 9 

 or Fig. 10, and is upset with a rivet hammer, Fig. 7. After the rivet is upset to fill the hole a rivet 

 set (snap), Fig. 7, is held over the upset rivet and a few blows with the riveting hammer completes 

 the work. Field rivets are ordered with enough stock to furnish metal to fill the hole and to 

 form a perfect rivet head. If the rivet is too short, either the hole will not be filled or the rivet
