. Railway mechanical engineer . Fig. 1—Hydraulic Press for Removing Coupler Yokes old hydraulic wheel press that has outlived its usefulness as such,and which is used for removing the yokes from couplers, isshown in Fig. 1. The yoke bears against a forked head in theoutboard housing, and the plunger of the press pushes againstthe body of the coupler, thus shearing the coupler yoke Fig. 2—Dies for Forming the Lips on Coupler Yokes The method of forming the lips on the end of the coupler yokein a bulldozer is shown in Fig. 2.

The yoke, having been bent,is anchored to the bed of the bulldozer within the arm, A. Asthe head of the bulldozer travels forward, the rollers B forcethe arms A against the yoke, thus forming the lips. The plungerC shears the lips to the proper length. Both operations are per- formed with one stroke of the head. The arms A are held in theopen position by the springs D. The machine used for riveting the coupler yoke to the coupleris shown in Fig. 3. It is a pneumatic riveter set into the floor
