An Auxiliary Car CouplerBY NORMAN McCLEOD In placing cars on tracks leading into industrial plants incities, considerable difficulty is often experienced becausesome of the curves are so sharp that the ordinary couplers donot have sufficient clearance to make the sharp turns withoutfouling. Handling cars with a link between the knucklepins is not satisfactory and the majority of emergency switching. They are made to fit the contour of the standardcoupler as shown in the detailed drawing of the head. Itwill be noted that a flange is provided at the top of the cast-ing. This prevents the head from slipping down through thecoupler with which it is engaged and holds it in the properposition while switching. The rod connecting the heads is.

It is not intended for handling long cuts, althoughseveral cars can be switched with the coupler if occasionrequires. 2^ ^ fT q» if* r i& r l^3i-j--#- Both EndsThus fcTM- t*1
