Abstract

22,211. Warner, J. S., Warner Engineering Co., and Mountain & Gibson. Oct. 20. Locomotive railway vehicles.-To minimize the disturbance to railway and tramway vehicles, and more especially that due to transverse irregularities of the track, the body is supported by links from a "major" truck frame turning about a king-pin, the major frame being in turn supported by links from a " minor " frame pivoted about the same or an adjacent king-pin. A third frame may in some cases be interposed. Fig. 1 shows a single-axle bogie having the body a suspended by links d from the V-shaped major frame e, adapted to turn about the king-pin j. The major frame is supported, through springs f, by links g swung on the minor frame h, which is supported by the axleboxes with or without the interposition of springs. Fig. 5 shows a double-axle bogie having a major frame e and a pair of minor frames h, all pivoted to the body by the king-pin j. The major frame may be in two parts corresponding to the minor frames h, and in this case the minor frames h may each be pivoted to the major frames by a separate king-pin instead of by the king-pinj. Restaurant cars, or carriages for transporting long pieces of timber &c., may be carried by a pair of these double-axle bogies at each end, each pair being connected by, for example a third X-frame or double V-frame upon which the body is mounted by centre bearings or by links as above described. The wheels on any one axle may be arranged to rotate independently of each other.
