A J^-in. curved iron plate forms the hood of thefurnace, the ends being left open. The furnace is inexpensiveto build, and has been found to work very satisfactorily wherecity gas is used in the shops. HANDLING COUPLER YOKES The photographs show three machines used for coupler yokework at the Plattsmouth, Neb., shops of the Chicago, Burling-ton & Quincy. They are noteworthy because of the fact thatbut for their present use they would have been scrapped. An. 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 rivets.
