SPECIFICATION forming part of Letters Patent No. 542,310, dated July 9, 1895.

Application filed March 2, 1894. Serial No. 502,153- (No model.)

To L7/Z whom t may concern:

Be it known that LJONAS PRINTZ, of Omaha, in thecounty of Douglas and State of Nebraska, have invented certain usefullmprove-` ments in Railway-Car Wheels and Tracks; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention has relation to a new and novel improvement in railway-car wheels and tracks, the object being to provide a simple means whereby the cars can be more readily propelled up an incline. A

In a great many cities where car-line grades are of necessity very steep much time is lost 'and power expended in carrying cars up the incline. During moist or icy weather a great many cars almost become stalled by the wheels revolving upon the track without moving forward. This slipping of the wheels is of course prevented in a degree by scattering sand on the rails; but as the riding-surface of the rail is narrow the sand soon works off. To provide a means whereby the cars can be more readily propelled up an incline is the object of my device.

In the accompanying drawings, Figure 1 shows a view, with the rails partly in section, of car wheels and trucks embodying my invention. Fig. 2 shows an enlarged detail of one of the trucks, while Fig. 3 shows a side view thereof.

A represents an axle of the usual size and conformation with the two wheels B B, which are as usual fixedto the axle A. These wheels are provided with the usual driving and guiding fianges. The guiding-{iange C in this -instance, however, extends at an angle to the wheel A proper, and comprises the guide- Iiange 2l and the friction-flange proper 3. This flange 3 of course forms an integral part of the wheel proper. To further insure the efficiency of this flange 3, I provide the same with a number of corrngations or depressions 5, distributed about this flange 3. The track upon which'this wheel is adapted to run comprises the main portion D, having the usual riding-surface and being'provided below lwith the approximately circular seating 7.

side with the angular seating 12, adapted to accommodate the'angular portion of the friction-rail E. This friction-rail is also corrugated or scalloped, having the depressions 15, within which those of the wheel readily work. Now these two-part rails E D are su pposed to be placed within the system at all points where gradesI are encountered. As soon as a car equipped with my truck strikes this track, the trucks leave the riding-surface of this rail D and are guided upon the friction-rails E, as shown in Fig. l, so that these anges support the whole weight of the car. By means of the bolts F these flanges may be given adjustment. As the upper edge of the friction-rail E wears off and out, the flangesection C is simply'reversed, so as to present the lower surface of this iiange, so as to make the same reversible and interchangeable. It is of course understood that this ange C could be without the corrugat-ions or scallops, as shown in Fig. 1, where the friction-dange of one of the wheels has been left perfectly smooth, as has also the friction-rail. It is also understood that, ifdesired, the rail D could be cast with an upwardly-extending frictionrail E.

Now, having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-

1. The combination with a car axle having suitable wheels, said wheels being provided with outwardly extending friction flanges, said friction flanges being scalloped, of atwo part rail comprising a main supporting section in combination with afriction rail, transversely in the shape of an isosceles triangle, the base of said friction rail being positioned vertically, and being reversibly and adjustably secured to the main part of said rai the angular sides of said friction rail being IOO i adapted to engage the friction flanges of said section in the form of an isosceles triangle, wheels, to support the same, all substantially and provided with the transvere opening, 9, as and for the purpose set forth. and the connecting bolts, F, all arranged to 2. The combination With the car axle, A, operate substantially as and for the purpose r4 5 provided with the Wheels, G, having the fricset forth.
