Y., as ' ~ Signor to William Platts Kellett, Bronxville, NY. Application October 4, 1935, Serial No. 43,477 9 Claims. The invention relates to articulated cars par ticularly applicable to the economical transpor tation of freight or goods in container lots and more particularly to improvements in brake ap~ 5 plying equipment therefor. The principal objects of the‘invention are to provide a simple but effective means operable from one of the car sections for uniformly ‘ap plying the brakes on both car sections and to 10 provide a brake-connecting means between the respective sections which will permit wide rela tive displacement of the car sections with the minimum effect on the braking equipment. The principal feature consists in the provision 15 of an articulated ?exible brake equipment oper able from one of a pair of car sections and hav ing an operative connection between the respec tive sections which is guided in special relation to the longitudinal vertical centre plane of the 20 car sections to e?‘ecti'vely brake the wheels of both‘sections of the car under varying conditions of load and position. In the accompanying drawing Figure 1 is a diagrammatic elevatio-nal view of an articulated 25 car to which the present invention is applicable. Figure 2 is a plan view of the coupled ends of the car sections, one section having the deck (Cl. 188-34) coupling such cars with a permanent ?exible coupling as shown but not claimed herein to thus provide a full length car having four, compara tively uniformly distributed wheel supports throughout its length, distinct advantages may OX. be achieved. ' In the structure herein illustrated a car com prises two sections A, B, each having a suitable frame l carrying suitable journal guides in which the axles of the wheels 3 are mounted equi~ 10 distant‘from each end. The frame 5 as. herein shown is preferably a unitary casting having a longitudinal box-like centre 4 with lateral arms 5 extending outwardly therefrom to support any desired form of superstructure carrying a deck 15 6, which will be provided with suitable guides and means for supporting the removable goods containers 1. ’ One end of each of such car sections A, B, is provided with any suitable form of draft rigging and the adjacent ends of said sections are per manently connected in an articulated manner by a draft rod 9 which may be suitably spring buffed. It will be understood that a car constructed in two sections connected together as described will be adaptable to» carry individual loads and removed showing the bare frame. such loads will, because of the arrangement of Figure 3 is a diagrammatic plan view of the wheel supports, be uniformly supported and the 30 articulated car showing the preferred form of ' articulated car will be free to ?ex vertically and ‘ 30 ?exible brake equipment. , horizontally intermediate of its length. Figure 4 is an enlarged plan detail of the sup A suitable braking equipment is provided on port for the ?exible brake coupling‘ arranged ‘each of the sections A, Home of which will be between the articulated car sections. directly connected to an operating brake cylin 35 Figure 5 is an enlarged elevati'onal detail of der and the other is connected through a ?ex the structure illustrated in Figure ll. ible connection to operate in unison therewith. ' The customary practice in American carbuild Referring particularly to Figures 3, 4 and 5, ing is to support a long and very heavy frame the car section B is provided with brake beams ‘between transverse bolsters carried on massive 52’ and is coupled to the operating lever [4, 40 trucks and as the lengths of ‘cars have increased, which is in turn operatively connected with the these frames have become exceedingly cumber main lever iii connected to‘ the brake cylinder some‘ and many extremely expensive forms. of l6 and brake wheel ll.

Cars .of one side of the longitudinal centre. half length are‘ in common use in Great Britain The car section A is provided with brake beams 50 and Europe and these dispense with the use of 22 and 2S operatively connected to an operating the extremely heavy and. expensive trucks. It is" not considered desirable practice to adopt the use of the individual short railway “wagon” 55. as above referred to for manyreasons but by lever M‘ which has connected thereto extending lengthwise of the car and coupled at the inward end to the chain passes; around a pulley 25 mounted on a rod 25 which is it which an angle 55 t2 2,123,423 bracket 21 arranged on the inward end of the operating with said ?exible member for operating car section A in a position offset from the centre the brake mechanisms of the respective cars si line a distance substantially equal to the offset of the pulley 20 and bracket 2|, the chain ex~ tending in a horizontally and transverse direc tion between the two. pulleys. The pulleys 20 and 26 are journalled on pins multaneously, said ?exible member having spaced portions supported on opposite sides of the said centre plane by the guide pulleys of the respec U! tive car sections with the intervening portion be tween the guide pulleys disposed in a plane trans 20’ and 26’ which are secured in a pair of bars ‘i versely of the said centre plane. 2.
