280 Varying the Gauge of the Wheels of Rolling Stock. 



in each of the clamps on the centre of the axle, thus admit- 

 ting of its alteration to one other gauge only, but of course 

 the number of these recesses might be increased and the 

 length of the sleeve altered so as to admit of its adjustment 

 to as many gauges as may be required. 



Having thus described the nature of my invention and 

 the manner of performing same, I would have it understood 

 that 



WHAT I CLAIM AS MY INVENTION IS: — 



First, constructing axles of railway rolling stock with an 

 extensible sleeve or sleeves to admit of the alteration of the 

 gauge of their wheels. 



Second, constructing such axles with a solid collar in the 

 centre and with a hinged clamp on either side having 

 recesses for receiving and holding the flanges on the inner 

 ends of the axle sleeves substantially as herein described 

 and explained. 



Third, The combination of the sole plate E, the rollers 

 E2, platforms F having recesses Fl (or their equivalent in 

 the shape of rails) with a right and left handed screw G, 

 turning collar G2 and thrust bearing G3, in the manner and 

 for the purpose herein described and explained.
