The manner of using the structure described
above will now be explained with reference to
Figs. 3 through 10.
As indicated in Fig. 3, it is usual to employ
two arch members 48 and 49, and three invert
members 50, 5| and 52. Fig. 3 shows the posi
tion of the traveler and the trolley beams when
the concrete has been poured around the arch
‘member 49 and the invert member 52 disposed
adjacent the heading 53. This concrete for the

lowers the trolley beams, but the hoists 45 can
be taken up to maintain clearance between the
invert forms 59 and 52.
The next step is to advance the traveler to the
position shown in Fig. 8. When in that position, 20
the invert form 59 is lowered into place, the rear
edge being secured to invert form 52, and the for
ward edge being supported on a'bulkhead 59. In
