Definitions

  • This invention relates to six-wheel trucks for railway cars and among the objects are:
  • angular journal actions are dependent and interdependent on a coordinating member connected thereto in such a manner that the several journals assume a position relative to the track contour which aflords the least resistance to the movement of the truck in either direction and are simultaneously held or locked in those (varying) positions which are governed by the track contour; also in means combined with: the several journal members of the truck that will functionate in the same manner on the central member and differently on the end members-with respect to the direction of the truck movement on the track; the pivoting centers of the end journal members located on the far side of the adjoining journals and such other matter and methods of operation as hereafter set forth or claimed.
  • This application discloses the same sub ject matter as our application for U. S. LettersPatent Serial No. 205405, filed December 4th,, 1917, which became abandoned through failure to prosecute within the statutory time.
  • Figure 1 is a top view of the truck with the coordinating member shown in full with the arms and the pivoting centers of the end journal members shown in dotted lines; Fig.
  • the wheels, journals and journal boxes 1, 2, 3, respectively, are all Master Car'Builder standards and said boxes are attached to and governed the journal members 4,.5, 6, each member being provided with pedestals that fit over the journal boxes 3, in the usual manner.
  • the pedestals at the ends of each of the members 4, 5 and 6 are joined together respectively by frames 14, 15 and 16, preferably formed integrally with said pedestals.
  • the middle frame 15 has two pins 8-8 rigidly supported therein and the end frames 14 and 16 are each provided with an arm 13, preferably formed integrally therewith.
  • the end of each arm 13 is bifurcated, one prong. extending over the middle frame 15 dand the other prong extending thereun er.
  • Both prongs are provided withholes for the reception of one of the pins 8 and each pair of prongs is mounted on the pin 8 which is remote from the end frame of which the prongs form parts.
  • each end member is pivotally connected to the middle member upon the pin 8 which is remote from the corresponding end member.
  • the outer sections thereo are joined together by tongue and groove bearings 9, whose radius lines, dotted on Fig. 1, extend across the central member to the pivoting point of the end member thus attached.
  • the end journal members 4, 6, are pivoted to the far side of the central member 5, to prevent any tendency of the journals buckling one on the other, which is likely to occur if the same are pivoted. between each other. Furthermore, the said pivoting centers produce a more concentric relation with the oscillations of the coordinating member 10 on its trunnions and the pivoting centers 8 of the end journal members, 4, 6.
  • equalizing springs can be inserted between the journal boxes and the pedestals thereof and body springs between journal members 4, 5, 6 and the coordinating member 10 which is set forth in additional patent applications.
  • journal and coordinating members are made of cast steel in one piece and after being machined at their bearing surfaces,. are ready for assemblmg, without use of tools, nuts, bolts, etc.
  • As the two end journal members 4, 6, are placed in proper relation to the central member 5, when the pins 8v areslipp'ed into position and the coordinating member placed over all with the trunnionsl-l in their counter .bearings and the pedestals 12 over the central member 5, which secureslthe whole together in working condition.
  • Thesaid arrangement forming modern interlocking construction that pro-.
  • the trailer member 4 is retained at right angles to the track to keep the oscillating point of coordinate member 10 in the 'center thereof in order to hold the several members in correct relation to properly take the curve, without suddenly jerking the car body and load toward the center of curvature of the track when the king pin reaches the-radius thereof, see Fig. 4.
  • the members 4, 5, 6, occupy the position shown in Fig. 5, in which position they are operated on the curve with the least resistance thereto and the center member 5 is held in that position by the coordinating member 10 during the traverse of the same, which when terminated the pilot member 6 takes the straight track at right angles thereto the other members responding accordingly, but vice versa when the direction of movement is reversed.
