Fig. 4 shows some strong points indraw-gear practice, that are worthy ofimitation. There is a 7 x i7^^-inch oakfiller, abutting against the rear draft lugsand body bolsters, and securely bolted tothe draft timbers, making an ideal job to and center plates of that type are popularwith many carmen, for the reason that thesteel pins will come out of a ruction inbetter shape than will the cast-iron centerplates, when the latter are made withshouldered bearing faces, and thus receiveall the shock. This difficulty was sup-posedly met when the steel plates were in-troduced; such plates now stand up allright, but the shear on pins is nothelped any by contact with the thin mater-ial of the plates, as made at is no doubt that this trouble wouldbe greatly relieved if both plates were. Fly- -i resist end shocks and save the draft-rigextending, as it does, from drawbar todrawbar on the center line of strain.
