RUBBER MONTING Fon can BODIES.
Application led April 6, 1927. Serial No. 181,842.
The present invention relates to rail car designs wherein the car body is carried upon a plurality of trucks in a well known manner and a suitable construction is provided enabling the desired pivotal movement between body and trucks to takeplace. In designs of this character it is necessary that a connection of a positive nature be provided between these elements so that the stability ot the car body will be preserved under all conditions of operation. The danger of excessive sway is apparent, and rough and uneven tracks and curves require constructions which will resist, successfully, the strains which tend -to disturb the equilibrium of the car body.
Although the above conditions must be considered, it is also highly desirable to interpose a shock cushioning means between the truck and car body to eliminate the objectionable metallic rail-joint click which 1s transmitted through the perfect metallic circuit direct from the rail comprising the wheels, journal bearings, truck, bolster, center plate, and car Hoor. In addition to performing the above function, a cushioning means of this character has other advantages which contribute to improved operation and include the smoothing out of irregularities in acceleration due to differences in application of power between the trucks where there are several driving trucks for each car. This quality also results in smoother operation where several cars are coupled together, since unequal draft forcesbetween the trucks of different cars will be absorbed by the cushioning means.
An object of the present invention is to provide an improved non-metallic and yielding connection between the trucks and car body of a rail car which will serve to ab- Sorb deleterious vibrations and shocks and prevent their transmission to the car body, without weakening the connection or impairing its adaptability to service ot this character.
A further object is to provide a connection of this type between the bolster and car trame which serves to cushion the car` body in the above manner but does not increase the side-sway of the car or disturb its qlilibrium at high speeds or on rough road Other objects of the invention will appear as the description proceeds and reference will now bel had to the accom anying drawings fpr a more detailed description thereof, wherein:
Figure l is an elevation, partly in section showing a proposed form of the invention and taken on the line 1 1 of Fi ure 2.
Figure 2 is a section taken on t e line 2--2 of Figure 1 and looking in the direction of the arrows.
Referring particularly to the drawin a represents the truck bolster and a t e bolster plate having a vertical cylindrical flange a2. A circumferential groove as extends about the surface of the flange to enable the body bolster plate to be movably secured to the truck bolster plate in a manner to be described later. A. bearing late atis provided in the recess within the ange a2 and carries the weight 'of the body upon the truck.
The body bolster is shown at b and the bolster plate at b. This bolster plate is'not integral with respect to the bolster and carries a bolt b2 which engages the groove as to prevent the two bolster plates from being separated while permitting relative rotary movement therebetween. A. cylindrical flange b3 is formed on the plate b and bolt b2 is2 carried by this ange as shown in Figure In the center of bolster plate b a downwardly extending stub shaft b4' is formed and carries the weight of the body. Bearing plate a* receives this member and in this manner, means is provided for turning one element with respect to the other.
A. seat a is formed on bolster and is similar in outline to the bolster plate b with which it co-operates. At the edges of the seat and bolster plate are formed vertical webs c and b5, respectively. These webs prevent excessive jellying of the cushioning element d which is carried between the seat and bolster plate. This cushioning element is composed ot' rubber or other suitable yielding non-metallic substance and has formed therein spaced grooves d which are adapted to permit uniform flow of the rubber under load. The cushioning block is formed with a central aperture d2 to conform to the recessed portion in the stub shaft b4'.
At suitable points in the seat, cushioning element, and bolster plate, aligned apertures c2, b are formed to receive through bolts e. Thermoid washers e are provided under the l bolt heads and within seats e. These compression and the entire structure consti.-
tutes a rugged connection ha-ving a cushioning eiect which absorbs the high frequency .low amplitude vibrations and somewhat dampens the heavier shocks to provide a more quiet ride andmateria-lly increase the usual life of the car body.`
The construction set forth herein is highly effective in preventing nosing of the car in rounding a curve', since the connection eliminates toa great extent, the jerking ofthe car body. Although the invention has `been set forth specifically and described as embodied in the drawings, it is not to be limited save as defined inthe appended'claims.
What I claim is: i
`1. In a mounting for a bar body, a truck, a bolster plate engaging thevtruck," vertical web on the bolster plate at its edge 4`to form a seat, a car body; a seat thereon andformed with vertically depending edges, non-metallic yielding cushlgning means, and means to secure the bolster plate to the body through the cushioning means rwhereby the latter is placed under a degree of compression inde# pendent/of the weight of the car body.
2. In a mounting for a car body, a truck, a bolster plate engaging the truck, a vertical Webon the bolster plate at its edges to form a seat, aca-r body, a seat thereon and formed non-metallic with vertically depending edges, a block of yielding' cushioning means formed to be received in the seats, rooves in the block, and means to secure t efbolste'r ,plate to the body through the cushioning means whereby the latter is placed under compression.
, 3. In a mounting for a car body, a truck, a bolster plate engaging the truck, a `vertical lweb on the bolster plate at its edges to form a seat, a car body, a seat thereon and formed with vertically depending edges,non metallic yielding cushioning means, cooper. ating apertures in the seats and cushioning means, bolts received by the apertures to secure the elements together and place the cushioning means under compression and means associated with'the bolts to prevent a metal -to metal contact between the bolster plate and car body. j
4. In a mounting for a car body, a truck, a bolster plate engaging the truck, a vertical web on the bolster plate at its edges to form a seat, a car bod a seat thereon and formed `with vertically epending edges, non-metallic yielding cushioning means, lco-operating apertures in the seats and cushioning means, bolts received by the apertures to secure the elements together and place the cushioning means under compression, said bolts being of a size to permit a clearance between apertures of the seats and the respective bolts, and non-metallic washers carried by t-he bolts to prevent a metal to metal contact between the olster plate and car body.
5. In a mounting for a car body, a truck, a bolster plate engaging the truck, a vertical web on the bolster plate at its edges to form a seat, a car body, aseat thereon and formed with vertically depending edges, non-metallic yielding cushioningmeans, co-operatng apertures in the seats and cushioning means, bolts received by the apertures to Secure the elements togetherand place the cushioning gneans under compression, said bolts being of` a size to permit a clearance between apertures of the seats and the respective bolts, grooves in 'the cushioningblement to permit the particles thereoif to flow when placed under compression, and non-metallic washers carried by the bolts to prevent a metal to 'metal contactbetween the bolster plate and fcar body.
