' To ALL wEOM' IT MAY OONOEEN:
Be it known that I, WILLIAM P. PARRO'TLof-Boston, in the county of Suffolk, and Commonwealth'of Masi sachusetts, have invented-certain new,and useful Improvements in Railway-Car Trucks; and I do hereby declhre that the followng,taken in connection withthefdrawings which accompany and form part ot' this specification, is a description of my invention suiicient toena'ble those skilled in the art to practise it.
My invention relates to theadaptation of railway-eerste run ilpon tracks of different gauges, the invention having for its object the lateral 'separation-and'drawing in of theopposite wheels upon, and by the tra ck-rails, se that the ear can be run from track to track by any ordinary motive-power. i
Until of late years, it has beencustomary, inthe laying and building of railways, to observe a iixed and regulated width between the rails, so that railways making connectionwith each other always had uniform tracks, and the cars running-upon one could be used'upon the other, and a cur, wherever built, had this ix'ed width between the wheels, adapting it to any and all-the railway-tracks of the country. More recently, however, railways have lbeen constructed of wider gauge, and` where wide and narrow gaugesconnect, freight and passengers have had to be transferred from the `cars of one road to those of the other, as, unless the cars were built with wheels made capable of .lateral movement with respect to each other, or to draw from oI- away'from `each other, to regulate their distance apart4 to the different tracks, employment of the same cai-s upon both was impossible.
To avery limited extent, cars have been constructed before my invention with wheels capable of such lateral movement, such wheels slidingi upon their axles; but in order to transfer them from track to track, it was necessary to raise the car-body and wheels above and free from the track, when the wheels were movedin the requisite directions, and the earthcnflowered upon'thc other track. By my invention, this operation of moving the wheels is eccted upon and by the tracklrails, so that the car does not have to be displaced from or raised above the track, but runs from one track to the other without impediment.' In the drawings- Figure 1 denotes a top view of two railway-tracks and a ear-truck.
' Y Figure 2 is a longitudinal section ofthe car-truck.
Figures 3 and 4 are cross-sections of the truck taken through one of the car-axles, and Showing the disposition of the wheels upon both wide and narrow tracks.
A A'denote the rails of the wide track, and B B' those ofthe narrow track.
a is the frame ofthe car-truck, 6' c e the wheels thereof, and d the axles. Each axle is shown as made in two parts, the wheels being conned in theusual manner upon the axles, andthe part e et' each axle being capable of sliding within aslceve or'tube, f, in the other part, so that they do notl rotate independently, but as one axle, a spline or pinand groove keeping them froml independent rotation, but allowing the wheels to separate or move towards each other..
When the car is upon the narrow track, the wheels are' confined in position by a pin, g, inserted in the axle, as 'seen in iig. 3, and when upon the wide track, .by insertingl the pin in other holes in the axle, as will be readily understood.
Between the opposite rails of each track, A A and` B B', are two inclined rails, C C', which constitute a connecting or wheel-changing track,`and parallel to' each rail, C C', i's a guide and wheel-changing rail, D D', and between these adjacent rails the car-wheels run from truck to' track, the wheels' being drawn together or. apart as the car may be passing from track A A. to track B B', or viceversa.
Suppose the car is in the position seen in iig. 1, and is to be transferred to the track B B', the pinl con- Y necting the two parts of the axle being withdrawn, as the caradvances the il'anges of the ywheels abut against' the inner'side ofthe rails C C', which causes Ithe wheels to move towards each other until they reach the parallel rails B B', when the confining-pin is again insertedvin the axle. If running i'rom the truck B B' t9 the track A A', the wheels'abut against the outer edges ot` the guard-rails D D', and Eire separated until they reachl the parallel rails A A. I
I do not intendto confine my invention' to the exact method shown of applying the car-wheels and axles to th'e ear-trucksas wheels-sliding upon axles,eal otherwise made capable of proper latcralmovement, may be employed. l p vI claim the combination and arrangement of a-car-truck with laterally-moving wheels, as described.
