the yoke, and that through bolts 20 extend through the several arch bars and through the hollow vertical members 8 of the yoke with a top arch bar, a lower arch bar and as clearly seen in Figure 4.
Thus it will be seen that the yoke so enters into the truck construction that it. becomes a part thereof in order that it may carry the journal box 12 and, ineffect, make a connection between the box, and'the frame generally. A very considerable number of the coil springs 10 may bev interposed as seen in Figures 2 and 8, because of the facility of providing thenecessary seats for them by reason of making the top memberl of the yoke of sufficient area to provide such seats, while a like number of seats for the springs are formed around the projections 11 on the box itself. 7
This multiplicity of coil springsbetween the truck as a whole and the journal boxes affords an excellent spring equipment for the springs is to vibrate rapidly and to yield to very minor as well as to major shocks. As I have ositioned' and situated this class of journal box and yoke, I produce a very desirable spring equipment and am enabled to use springs made of rods of comparatively small diameter Without any risk of the springs tending to topple over by reason of the weight upon them.
. The vertical guidance, of the journal box by the yoke and the secure seating of the springs to the box and yoke are factors which prevent the springs from toppling over sidewise but rather keep them in a vertical attitude so that they respond quickly to jars. I 7 Any conventional journal plates or bushings 22 may be employed betweenthe journal 23 and the Figure 3. j
I prefer also to form the lower cross member 6 ofthe yoke in'the manner shown in 'Figures3 and 7 so as to constitute a seat 24 for the lower arch bar 3 to prevent. any lateral shifting of the yoke at its lower end with respect to this arch bar.
, Thus it will be observed that I have provided a combination of a yoke, journal box and springs,and acombination of yoke and arch bars of the truck which comprise a structure that is rigid and strong and yet in which the journal box has freedom of vertical movement while being amply ,se-
' cured and properly guided. I
It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to r V varying conditions and uses.
7 Having thus fully described myinvention,
The natural law of these coil or helical.
ournal box 12' as seen in what I claim as new and desire to secure by Letters Patent, is: r
1. In a railway car truck, the combination an intermediate arch bar, of a yoke secured to all of said bars and positioned between the top and intermediate bars and the lower bar and having vertical members forming guides, a journal box mounted in'the yoke and guided vertically and laterally thereby, and springs interposed between the top of the yoke and the top of the journal box.
2. In a railway truck, the combination with the arch bars thereof, of a yoke comprising a casting forming upright hollow members constituting guides and transverse members, a journal box slidingly mounted between said upright members andguided thereby, through bolts extending through the hollow members of the yoke and securing the barstothe yoke, and helical springs mounted between and attached to the upper part of theyoke and the top of the journal box. v
3. In a railway truck, the combination with an upper and an intermediate arch bar, the one resting on the other, and a lower arch bar, of a yoke positioned between the lower bar and the intermediate bar and having hollow upright portions which form guides,through bolts passing through the several bars and said hollow members and having nuts to secure the parts together, a
journal box having vertical surfaces fitting against two sides of either hollow member, the upper face of the box and the lowerface of the upper member of the yoke having circular shoulders forming seats for springs, and coil springs titted about said shoulders and locked between the box and that part of 1 the yoke. Y
4. In a railway truck, the combination with a yoke comprising a casting having cross members and hollow vertical members,
of a journal box having right-angled vertical.-
guiding surfaces embracing two sides of-the vertical members, and coil springs positioned between the box and the upper part of the yoke and having a connectionwith each of them. 7 e v In testimony whereof, I afix my signature.
THOMAS ELLIOTT.
