The demand which led to the design of the third typewas for a light drawbar applicable to the customary citycar or light trailer, which would readily intercouple withthe drawbars of the Nos. 21 and 11 type now in use onheavy interurban cars, as well as with the Nos. 5 and 5^2heads largely used in city service. To meet this demandthe No. 27 head was designed. This is a medium betweenthe Nos. 11 and 21 heads and the Nos. 5 and $]/2 heads, isextremely light, weio-binp; but 40 lbs., and the pins and links.
