Such an arrangement may be necessary and advisable where the cou pler moves a-great distance laterally, such as in K passenger train cars. The object of such `con the railway car is upon a curved track. 20 struction, is to ,limit the distortion of the springs Another object of the invention is to provide a as excessive and frequent distortions may cause »resilient means in a carrier for supporting the fatigue of the metal and breakage of the spring. outer end of a coupler at a desired elevation dur The .distance two couplers are out of alignment ing service movements of the car, but which means permits downward and/or lateral move ment ofthe coupler when an additional live load is applied such as when two coupled cars are pulled over a track elevation, hump, vertical curve in the track, or around a curve, and wherein said and Will still couple iscalle'd the coupling range. Throughout `the specification, wherever the lterm “coupler” is used, it is understood to mean a y carrier, when free to do so, will return the coupler Also in the modiñcations of the invention some of the elements'rolksome rock and some do both to its normal height and simultaneously to a position at least adjacent the center of the car Within coupling range. Another object of the invention is to reduce the standard railway car coupler wherein no provision is made for the coupler to rotate around its longi tudinal axis. s simultaneously, therefore, applicant has used in Athe speciiication and claims the word “rock” , (and derivations thereof) with the understanding service stresses in the coupler by `providing a; that, for the purpose of describing the invention, resilient coupler carrier thereby permitting the theterm includes a rocking and/or rolling action. outer end of the coupler to move vertically so In the drawings: that the center line of coupled couplers will be Fig. 1 shows the striking casting of a railway nearer a straight line, thus reducing the resultant car withy my device appliedthereto. force in the coupler shank.
