The deck and shell riveter illustrated in Fig. 3 at-■ tracted a great deal of attention, as probably one of the mostimportant of recent improvements in ship building glance at the engravings makes the construction clear andshows the convenience of the device. A long stroke riveteris so mounted in the end of a U-section beam that it may in any direction to reach a rivet. By means of an. Fig. Riveter. adjustable block, the beam is clamped at the middle of itslength and the end of the beam opposite the riveter has asupport in the form of a rod with a number of grooves wherebyan adjustable support of this end may be had by means ofa latch. This device renders it easy to reach a large numberof rivets with one setting of the central support. The costis from one-half to one-third of that of hand work. It isdone: by ordinary labor and renders ship builders independentof riveters unions. Other manufacturers of pneumatic tools were also well rep-resented at the Paris Exposition, notably the Q. & C. Com-pany, the Standard Pneumatic Tool Company and others, thosementioned having been in competition for the official Chicago Pneumatic Tool Company received from the Inter-national Jury of .\wards a gold medal, and a second gold medalwas awarded to Mr. Boyer as collaborator and inventor of thetools, giving the two gold m
