THE ATTENTION OF RAILROAD COMPANIES is respectfully invited to an examination of the merits of thisvaluable invention, which offers to add largely to the safety of life and property. The valuable features of this arrangement of axle are, a saving of full fifty percent, in motive power on crookedroads : the rails are protected from being destroyed by the flanges of the wheels coming in contact with them onthe curves, as is the case with the stiff or rigid axle, which not only destroys the rail but puts a constant strain uponthe wheel and axle, causing the wheel on the inner rail to trip or revolve upon the rail under the weight of tbe carand its load, while the opposite wheel is traversing its greater distance; the tendency of which, is to wear thewheel flat, and cause it, or the axle, to break sooner or later. There is less danger of the car leaving the track fromits having become spread. Axles
