THE FIRST EQUALIZERS. Harrisons first equalizers were madeof cast iron, very heavy and clumsy andwere hung above the frame just as theyare now in 8-wheeIers, the ends bearingon round pins that went down and restedon the top of the box. Mr. Harrisons The engine built upon this order wasknown as the Gowan & Marx (), which became one of the mostfamous, locomotives ever built. The engine was of the eight wheeltype, and in order to properly distributethe weight, the rear axle was placed underthe firebox, just as it is now placed undersix and eight coupled engines. Theboiler had a Bury dome firebox 5 feetdiameter. Two-inch tubes 9 feet longnearly filled the cylindrical part of theboiler. The cylinders were i2jjxiS inches, and.

This device madeit possible to use any number of drivingwheels on the roughest track, and to that time, the most useful im-provement made on the locomotive en-gine. EQU.\LIZERS DISCREDITED. The other builders condemned the useof more than one pair of driving wheels,and did not, for some time, credit theequalizer with any merit. Mr. Baldwinsaid he could not see how the enginewould curve without slipping some of thedrivers, and he thought it impossibleto maintain all four wheels exactly thesame size and thought them complicated;but their good points were forced uponhim by their service, and, in 1845, hebought the patent of Mr. Campbells8-wheeler, and that of the equalizer ofEastwick & Harrison, and at once turnedout his first class C engin
