two spaced upright struts I2 and I3 forming eye

The adjacent links consist of side bars I4 which
overlap the link II and are pivotally connected
thereto by a rivet I5 which may be locked in the
side bars against turning, the rivets finding a
bearing seat in the curved portion I6 at the ends
of eyelets adjacent the oblong slot. With this
construction, the alternate block and side bar
links may be connected to form an endless chain,

The projections on the two half flights arek
apertured as at 23 and 24 so that when assembled,
locking means, such as bolts 25 and 26 may pass
through them to secure the assembled flights
from sudden movements which might serve to
disengage them. As illustrated herein, the pro
jections I8 on the Hight halves are spaced apart
50 by a pair of washers 21 through which the bolts
25 and 26 pass and the bolts of course are re
tained by suitable nuts 2B.
By making the separate cross flights of identi
cal construction, interchangeability of flights is
possoble and the user of the conveyer need only
stock one type, making for economy, ease of
manufacture and simplicity in replacement.
Also it will be noted that the forces exerted
against the face of the conveying member are
transmitted to the sides of the` chain link, where
they are divided and brought into opposition with
themselves and made to bear on the sides of the

special devices or links. Thus, without discon
