12 Claims.
This invention relates to railway journal boxes and comprises all of the features of novelty herein disclosed. An object of the invention is to provide an improved driving connection between a wheeled axle and a driven shaft such as that of a generator mounted on the journal box. To these ends and also to improve'generally upon devices of the character indicated, the invention consists in the various matters hereinafter described and claimed. In its broader aspects the invention is not necessarily limited to the specific constructions selected for illustrative P poses in the accompanying drawings in which Fig. l is a vertical sectional view through the outer portion of the journal box and appurtenances.
Fig. 2 is chiefly a horizontal section, parts being broken away.
Fig. 3 is partly a section and partly an end view of Fig. l to smaller scale, parts being removed.
Fig. 4 is a perspective view of a coupling.
Fig. 5 is an end view of a driving member.
Fig. 6 is chiefly a central section of the driving member.
Fig. 7 is a sectional view of a splined sleeve.
Fig. 8 is an end view of the sleeve.
Fig. 9 is a view similar to Fig. 1 showing a modification.
Figs. 1 and 2 show the outer portion of a railroad journal box or axle housing I0 containing a raceway sleeve I2 for two rows of roller bearings H running on an inner raceway sleeve I6 pressed on an axle 18. The box has a pad on the top supporting the usual equalizer plate 22 and the sides of the box have the usual pedestal flanges 24. At the end of the sleeve I2 is the usual oil collecting ring 26 which delivers oil to a pan 28 on a cover 30, the pan delivering oil to passages on a thrust block 32 which is centrally perforated and clamped against a transversely extending end wall 34 of the box by a flange on the ring 26. The axle is free to shift axially to engage the thrust block.
The end wall 34 of the box which extends crosswise of the axle has an opening in line with the axle center and a flanged bushing 36 is pressed into the opening. A driving member in the form of a sleeve 38 is journalled for rotation in this bushing and its inner end has a series of teeth or splines 48 for driving engagement with more elongated internal teeth or splines 42 formed on a sleeve 44 which is pressed in the axle. The axle end of driving sleeve 38 is no larger than its journalled portion so that it can be withdrawn or inserted endwise through the bushing 36. Welded on a seat at the outer end of the sleeve 38 is a projection comprising a cross arm 46 having driving pins 48 entering radial slots 49 in a spider or coupling plate 58. shouldered pins or studs 52 with square heads enter slots at 90 from the pins 48 and are carried by enlargements on the ends of an arm 54 whose hub is keyed to a shaft 56 and locked by a nut 58. The shaft 56 is illustrative of any driven or driving shaft in approximate alignment with the axle and having a loose connection therewith through a flexible coupling. The shaft is shown as the driven shaft of a generator and is journalled near its inner end in a ball bearing 60 carried by an extension 62 of a generator casing 64. This generator is of known kind and its casing has a flange 66 fitting in an adapter plate 68 which is removably bolted on the end of the box. The flange 66 is secured to the adapter by a clamp ing plate 59. The adapter, generator and its driving means are removable from the box in which event a cover 18 indicated in broken lines in Fig. 2 is bolted on the box in the place of the adapter.
The end of the generator shaft 56 abuts against a plunger comprising a round nut 12 which is threaded on a bolt I4 extending through a coil spring 16 contained in a bore in the driving sleeve 38. The spring bears against the nut l and reacts against a shoulder on an internally projecting portion 18 of the driving sleeve 38. The head of the bolt lies in a recess of the driving sleeve and is adapted to engage the projecting portion 18 to limit outward movement of the plunger. In use the plunger engages the generator shaft and the spring reacts on the internal projection 18 of the driving sleeve 38 to hold the arm 46 against the flange of the bush-- ing 36. Thus endwise shifting of the axle will not tend to move the driving sleeve 38 to the right. The splines in the sleeve 54 are longer than the splines 48 on the driving sleeve '38 so that there is always driving connection. even when the axle moves endwise. Thus power from the rotating axle drives the generator shaft from which current may be extracted in the usual way to control brakes on the car or for other purposes.
Fig. 9 shows a modification wherein a box projection 80 extends outwardly a considerable dis tance from the end wall 82. The end wall has a flange or circular boss supporting a long bushing 86 which provides a bearing "for a driving sleeve 88 containing a spring pressed plunger 98 similar to that of Fig. 1, the driving sleeve 88 being elongated and driven by a slip connection with the axle in a similar way. A cross arm 92 secured on the driving sleeve has enlargements for driving pins 94 engaging a spider or coupling plate 96 similar to the spider 50. The spider may have the same kind of connection to the generator shaft as in Fig. 1 and the generator casing may be mounted in a similar adapter. The pins 91 are formed on studs 98 threaded. in the enlargements and are or may be the same studs which are threaded into the end of the axle in other kinds of journal boxes for direct connection of the axle with the coupling plate or spider. Such boxes however are not closed at the front or outer end.
