, is necessary or desirableto provide means bottom of the car of a universal wheel or pulley 36, wh ch guide is shown in Figures for holding the wheel in a substantially vertical plane, while' permitting it to swing in a horizontal plane. One form of such 6 and 7 in which a bar 29 is pivoted at 30 to a bracket 31 secured to the truck frame 11. Two wheels or rollers 32 are carried by the bar 29 and en. gage withthe opposite sides of the rim 26. These wheels or. rollers tend to hold the pulley upright while permitting it to swing in a horizontal direction as indicate-d by the dotted lines in Figure 7. 7

The generator 33 is hinged at 34 to the 35 and is driven by means is similar in construction to the pulley 14. However, in this instance the rim 37 is not split. The hub 38 is connected to the rim by bent spokes 39 and is split in the'plane of the wheel, the parts being held together i by bolts 40. This hub has a bearing or tusprings 49 are bular projection 41, which is secured to a shaft- 42 of the generator by means of set screws 43 or in any other suitable manner.

A. bracket 44 is-secured to the generator and has a bar 45 pivoted thereto at 46. This bar is provided with guide rollers 47 to enwith the rim 37 for guiding the pulley. A drivin belt 48 passes around the pulleys 14 and 36. One or more adjustable arranged to pull on the generator 33 so as to keep the belt tightened at all times. V

"In the modification shown in Figure 9,

the pulley 36 is provided with two guide rollers 50, which engage with the same side of the wheel, one being at the top and the other at-the bottom. These rollers are carried b arms or bars 51, which are pivoted at 52 to brackets 53 secured to the'generator, It will also be noted that a similar modification'may be utilized with the pulley 14,

, although "I prefer the arrangement above described. 7

With this approved form of transmission, the pulleys on the axle and generator will always stand in the same vertical plane or be in alignment'withreach other and with V the belt. i Consequentlya proper driving relation is always maintained and there will be little or no chance of the belts being It will 'also'be noted that the device can be readily taken off, of one car and applied to another, or new parts supplied which fit va rious sizes of axles. l

7 It will also benoted that various changes may be made in the details of construction and arrangement of the parts in order to apply the transmission to various types of cars-andtherefore I do not wish to be limited 'to the particular arrangement herein ing sockets formed integrally therewith,

bent spokes engaging with said sockets, a split hub for receiving the inner ends of the spokes and means for fastening the hub to a shaft of a railway car. 7
