The larger of the two engages with the hookin the usual way, and the smaller open link tits in the linkslot of the knuckle and requires the use of a coupling buffers used on British carriages and goods wagonsmaintain the vehicles at the proper distance. The Drop Test as a Means of Showing RelativeStrength of Draft Gears Irwcrdinijs of the Western R,i. Club. 1000, p. 160. Mr. R. P. C. Sandersons paper on the above-named subjectdetails some tests made by the A., T. & S. P. R. R. Theweight of the drop was the usual lbs. A number of dif-ferent draw gears were subjected to experiment, with vary-ing results. Mr. Sanderson is emphatic in saying that thelug or turndown lip on the yoke or pocket to grip the shoul-der of the coupler is an absolute necessity. He also main-tains that the breakage of yokes demonstrated that nothi
