In the accompanying drawings: Figure Il is a vertical longitudinal central section through e. drewber appliance, illustre-ting an application of my invention; and, Fig. 9i, a vertical trensveree section on the line of Fig. l.

Under certeinstructnrel conditions, es in tanks, end'locomotives on which certain de -signs 0ic stoking mechanism are epplied,

drevvber pins cannot be inserted from above '.5

the drawbar, and it therefore becomes necessary to adopt some means 'to prevent tliem, when inserted from below, from accidentally dropping down and out of the drevvber..
