I This earlier Miller (who we believe was a cousin of Ezra jMiller, the inventor we are speaking of) showed two hookswith a single bevel, but each pivoted in a bumper-box ofold and well-known construction. The hooks were sepa-ated not by a sidewise motion as in the 1863 Miller patent,but by an up-and-down movement. Fig. 2 is taken fromthe 1854 patent of Miller, showing the parts partly insection. that they were forced to couple and remain coupled bythe springs Z) Z*. If no buffers or bumper-boxes wereused, then the two ends of each hook would strike the. Fig- 3. JONES COUPLER, 1855- cavity in the opposing hook, and a buffer would be thusformed. The patent of E. L. Keeler, No. 24,938, dated Aug. 2,1859, showed two hooks disconnected from any couplingor bumper-box. The hooks were separated by rotating Vol. LXI, No. 9 ] ENGINEERING JOURNAL. 402 them.
