A look at these illustrations 

 will show you 



how the Reciproca'ting Grinder is re- 

 moved from and replaced upon the track 

 without interfering wiih movements of 

 cafs. Under ordinary conditions, 



Grinding re- 

 sumed. Time 

 consumed 40 

 seconds. Car 

 not delayed

Only 40 



need elapse between cessation and re- 

 sumption of grinding. Any crew can do 

 is, any day, with the Reciprocating 

 Grinder — and some crews are doing it 

 in 25\econds.

The reasohvwhy the Reciprocating 

 inder can be ficbodled so easily is, that 

 se of a reciprocating instead of a 

 rotating grinding element makes possible 

 the construction of a light, simple ma- 

 chine which can be run by common 

 labor. 



It cannot be made to damage the 

 track, and will surface uneven joints, 

 producing a gradual taper or run-off on 

 both sides of the joint by removal of the 

 minimum amount of metal and with 

 minimum consumption of power.
