RAILWAY VEHICLE AND TRACK anarrastn TO CHANGE or'eaen.

To all whom it may come-raj:

lie it known that I, JAMnsHAnrna NEW- row, a citizen of the Commonwealth of Australia, residing at Sydney, New South V ales, in the Comn'ionwealth of Australia,

have invented. new and useful Improvements telat ng to Rallway Velncles and Tracks Adaptable to Change of Gage, of which the following a specification.

The object of this invention is to provide some cases the superstructure of such vehicles have been made interchangeable with the bodies of other vehicles, and are lifted from the rolllng stock running on one gage of rails to rolling stock adapted to run on rails set at a different gage. This occasions considerable delay in the transport and delivery of both merchandise and live stock. To obviate these difficulties, and to insure the vehicles running safely on either gage rails, this invention provides means whereby the wheel axles, which are formed in two. equal lengths, are caused, while running, either to lengthen or shorten automatically at the station where the two gages are joined by a double set oi. tapering lines.

. Referring to the accompanying drawings,

:in which similar letters are used throughout the diiierent views to indicate similar parts: Figln-e 1 is an elevation ofan extendlble axle and wheels set tonarrow gage lines,

with horseshoe strap and block piece in elevated position, central supporting hearing, and, thesuspending frame, all shown in longitudinal sectional elevation. Fig. 2 is anelevation and section of the parts in Fig. 1., but extended to the wider gage lines, with strap and block piece lowered into position between the ends of the half axles. Fig. 3 is a central longitudinal sectional elevation of a half axle, enlarged, showing the cir ail ar and roller bearing and oil feeding chan- Specification of Letters Patent.

Fig. 1.3 is a half lan oi Fig.

12, with gradient track in col apsed posrtion, wheels and axles being omitted.

This invention confined prlncipally to the reconstruction of the axle parts of var ous kinds of: railway vehicles, but exeluding locomotives. w Q

he type of axle illustrated is especially serviceable for railway vehicles having overhan in axle boxes. In such the framework 23 i2! 0 than the over-all wid th ot the ore an extenchble axle may be ing, while the inner journal A, formed be tween the collars A" nd A'flhas its special bearing G to lsu sport it, two of whichare provided in the ha longitudii'ially and securedby tlie bolts D to the under carriageattaclnnent F. The

collars A, whichin Fig. 1 are shownin 110' their close position, are provided with nger D, which is divided wheel axles and central. bearings, andshow- The outer journal A would Lrunin the usual. overhanglng axle box bearice bearings A held in position by the screw threaded ring A, side Fig. 7. The circular track in this figure is shown of larger diameter than in Fig. 8, for the purpose of insuring that the balls in each case will take their hearing on the contiguous aXle end without coming into contact. The means for lubricating these bearings is by the central oil channel A which is also in communication with the oil feeding channelA for lubricating the journal A The journals arenecessarily longer than their bearings to provide for the lengthwise movement, which is equal to the difference be tween the two gages on which the wheels are required to run. The fixed collar 13 is provided as an additional means for securing the wheels a screw threaded bolt B serving the attachment. The chambered par-ch? serves as an oil receptacle for lubrieating both the bearings C, the inner collars A, and the ball bearings A The distance block F, which is essentially of a width equivalent to the difference between the two, gages, is likewise lubricated by means pf the revo-lving collars A as they run in the oil bath. These collars take their bearing against each other when the block Fis raised above them, as in Fig. 1, but in its lowered position, as in Fig. 2, it serves as a thrust block separating the two inner collars, and having the ball bearings A in Contact with the sides. This occurs when thewheels B are at their widest gage. The upper guide fian'ges D of hanger D, being held in position between the side parts of the under carriage attachment E, serve the purpose of a chamber G (Fig. 2) for the block F to slide in, it being secured to the horseshoe strap H by the bolts H The said strap is retained within guides formed by the projecting pieces I (Figs. 4, 5, and 6). The st raps and block piece move together when the former is brought into contact with the collapsible gradient track 1 which comprises the gradient part J and the level part J the former being serviceable for producing the lifting movement to the strap H, while the level part is used to maintain it in the elevated position until one pair of wheels have PHSSQCl fIODI the broad to the narrow gage, the level part bemade essentially of a length equal to the distance to betraversed by the wheels from one gage tothje other. It is necessary that theblock piece F be lifted quite clear of the "collars A before the axle A commences the shortening movement, which is brought about by confining the flanges of the wheels between the rails K and K which converge fron the broad to thenarrow set of rails. The 'removalof the block F insures this taking place, and when the narrow gage is reached the saidblock takes its position on the top of the collars A": When the strap H is free from the track J it will be seen that the block F will remain supported upon the collars, as in Fig. 1, until the movement of the vehicle is reversed by passing it from the narrow to the broad gage; when the lengthening of the axle takes place, and the block F, by its own gravity, descends into the position indicated in Fig. 2.

To permit of the gradient track being laid in the prone position, as in Fig. 11, the sloping part J is pivoted to the level part J by the pin J the said'level part being, in turn, secured by means of pin connected links J? also attached to the fixed chairs J upon thesleepers L. The part J is supported centrally by the pin connected link J attached at its lower end to the slide block J 6 running upon the incline M formed at the inner end of the bed plate M To the link J is attached the connecting rod N secured at its other end by the pin J to the slide block 0, which is also connected to the jointed lever secured at its outer end by the pin P to the slide block The cen ter pin P connects the jointed lever with the cranked lever Q attached to theoperatiiig spindle Q supported in the bearings R. This crankedlever is causedto pass from its forward to its backward position by means of the operating lever S having a 1 weight S to retain it in p dsition. i

Fig. 11 shows the device in its prone position', with the slide block J 6 moved down the sloping part M, and the slide blocks .0 andO moved along the level part M of the bed plate M The parts J and J are thus put out of action, and prei' entedfrom being an obstruction to trafiic. i

Having now described my invention, what I consider novel and desire to secure by Letters Patent is:- i

1. I A railway vehicle aXle divided into two interchangeable parts, each part being of an equal length and of similar formation, such formation comprising the outer ournal made longer than the width of the bearing in which it is supported, the inner journal also made longer than the width of the bearing in which it is supported, the said inner journal being formed between collars which serve asstops to control the outward and inward movementsof the axlelpairtsfcontiguous to the end collar of such journal the circular roller bearing formed in the end of each interchangeable part of the axle, the diameter .of the said roller bearing on the one part being largerthan the, roller .bearin on the other part so that when thehalf parts arecontiguous to eachother the ball hearings on the one end of the shaft will bear against the end of the adjacent shaft, eachsaid half part of the axle having a centrally located oil feeding channel ex tending its entire length, and a channel communicating therewith and 'with the inner journal, and being, further provided with a collar as a rneans of attaclnnent with a screw threaded bolt to the axle wheel, as described and shown, and for the purposes set .liorth.
