It is also to be noted by reference to Fig. 6, that
the upper run of the conveyor is the only working
run and in this illustration there is no bottom or
trough forming plate on the return run of the
conveyor, comparable to the plate 26. If it is
desired, however, to employ the return run as a

working run, this can be done by the simple ex

of a plurality of upwardly and longitudinally 10 pedient of providing a bottom forming plate

extending articulated overlapping plates 24 and

The side plates 24 and 25 not only act to
provide the articulated side walls of the trough

as side bars or side straps of the endless articu

3 of the drawings. Each of the chains il also
includes overlapping outer side bars or side straps
or plates 2l, and each link of the chain is thus ,_
formed by a side bar or plate 2'1 and a side plate
213 or 25. The side bars or straps 2ï have a much
less height than the side plates 22 and 25, as
clearly illustrated by reference to Figs. 4 and 6 of
the drawings.
The links of each of the chains Il also include
spaced pivot pins 28 which pivotally connect

scribed, particularly in connection with Figs. 3, 4
and 6.
The principal differences will now be
described.
First of all, the conveyor chains I’l are pivotally
connected near the bottom of the side walls 23
of the trough 2|, as Viewed during the working
run, rather than substantially along their middle
transverse axis, as in the case of the structure oi'

rollers |22» which are without flanges. Also, the
return or bottom run, as illustrated in Fig. '7 cf
the drawings, is illustrated as a working run, as
it is provided with a bottom plate |20 which co
operates vvith the articulated side walls 23 to pro

other obvious differences, it is to be understood
that the structure oi the conveyor mechanism
of Figs. 5 and 7 follows that of Figs. 3, 4 and 6.

chains i7 are preferably of the roller type in the

broader aspects, they need not be of this type.
