the Gauge of the Wheels of Rolling Stock 279 



In order, however, that my invention may be more 

 perfectly understood, I will now describe the same with 

 reference to the accompanying drawings, in which Fig. 1 

 shows a side elevation, partly in section, of a pair of wheels, 

 provided with my improved axles, resting in the recesses 

 upon the platforms of my improved' machinery as they 

 would be just previous to narrowing their gauge. Fig. 2 is 

 an end elevation of the same. Fig. 3 a plan of the machin- 

 ery alone, and Figs. 4 and 5 detail views of the hinged 

 clamps. 



AA are the wheels which may be of any description so 

 long as their bosses Al are large enough. B is the axle with 

 solid collar Bl in the centre. B2 are steel feathers properly 

 secured to said axle. C are the sleeves terminating in 

 flanges CI. DD are the clamps or hinged collars having 

 two recesses Dl and D2 in each. D3 are the hinged bolts 

 having plate washer D4. D5 are the bolts through the 

 clamps and the solid collar of the axle and having connect- 

 ing plates D6 at either end. E is the sole plate of my 

 improved machinery firmly bolted to a solid foundation, and 

 El and E2 are the two sets of rollers thereon. F are the 

 platforms carrying recesses Fl and nuts F2. G is a right 

 and left handed screw with turning collar Gl and thrust 

 bearing G2. 



The mode of operation is as follows: — When it is desired 

 to use the rolling stock of a rail or other permanent way 

 upon another way of different gauge, my improved 

 machinery is placed where the break of gauge occurs. To 

 transfer the rolling stock, the rails or recesses Fl on the 

 platforms F of such machinery are set by means of the 

 screw G to the gauge of the line on which the stock is. A 

 vehicle provided with my improved axles is then pushed 

 upon such platforms, the clamp bolts D3 of such axles 

 unscrewed so as to admit of the clamps being opened on 

 their hinges T>5, so freeing, the flanges CI of the sleeves C, 

 to which the wheels A are keyed. The rails or recesses on 

 the platforms are next adjusted by means of the right and 

 left-handed screw G to the gauge of the line upon which it 

 is desired to run the vehicle. The flanges Cl of the sleeves 

 C on the axles should now fit in another recess D2 in the 

 clamps, which are closed and tightened up as shown in 

 Fig 4, and the vehicle then moved on to the second line. 



In the drawings illustrating this invention the vehicle is 

 shown at its widest gauge and with only one vacant recess
