I have never found a Triple Lock Schematic. But the Mod 24 .44 spl Schematic found here at Gunparts:
Smith & Wesson 24 Revolver Parts, Schematics | Gun Parts Corp.
is almost as good with a few revisions that I've listed with correct part names and photos below :

#1 Extractor Rod – TL difference: the Knob is removable for disassembly and part # 4 extractor rod collar (the seat for large extractor spring) is integral with the rod, not a separate part.
# 2 Center Pin - TL difference: part #3 ctr pin spring mounts on the rear end of the ctr pin because it is spring tensioned to the front (that's the reason there is no 'divot' in the recoil shield to cam the ctr pin forward when closing the cyl). Note: instead of integral collar on the ctr pin, the triple lock ctr pin has a tiny 'E' style spring clip and washer.
#3 Center Pin Spring
#4 Extractor rod collar (the seat for large extractor spring) is integral to the ext rod on the TL.
#5 Extractor spring
#6 Gas ring – press fit in front of the cyl.
#7 Cylinder
#8 Extractor alignment pins, press fit
#9 Extractor assembly, often referred to as the extractor 'star' or 'ratchet'.
#31 Yoke (called crane on Colt DA revolvers) – the TL 3rd or middle lock cam plate is mounted in the front of the yoke with a screw.
#66 Locking bolt – TL difference: the TL front & middle locking bolts are one piece including a spring, plunger, and cross pin; the lower leg (middle lock bolt) being much longer to contact the cam plate in the yoke. It's retained by a hole plug (cover) at the front of the shroud and two pins thru the ext. rod shroud instead of just one as shown below.
All the other parts of the TL are the same part names and listed at the link above (although not necessarily interchangeable with the TL due to slight dimensional differences). The post war hammer block safety parts do not exist in the TL and the Micro Click target sight shown is of course different from the TL style pre war sight.
