Abstract
Particles, devices and methods of increasing rail road train traction and reducing wheel/track noise. The invention provides hard metal particles which can be embedded into a rail head to minimize slippage for improved locomotive traction and reduced oscillations of train wheels which cause noise and track wear.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A device for application of traction particles to rails, the device comprising:
a) a grinding wheel; b) a metal source in contact with the grinding wheel, which metal source is ground and/or cut by the wheel to provide metal particles; and, c) a roller; whereby a first rail receives the metal particles; and, where after the roller presses the metal particles into the first rail.
2 . The device according to claim 1 , which device is mounted to a rail road carriage.
3 . The device according to claim 2 , wherein the carriage is self propelled.
4 . The device according to claim 1 , wherein the grinding wheel is driven by a motor.
5 . The device according to claim 1 , wherein the grinding wheel comprises a grind stone, a carbide cutting wheel or a diamond cutting wheel.
6 . The device according to claim 1 , wherein the metal source is harder than the first rail.
7 . The device according to claim 6 , wherein the metal source is selected from the group consisting of tool grade steel, stainless steel, carbide steel and titanium alloys.
8 . The device according to claim 1 , wherein the metal source is directed and urged into the grinding wheel with a feed mechanism.
9 . The device according to claim 8 , wherein the feed mechanism further comprises spring pressure.
10 . The device according to claim 1 , wherein the metal particles range in size from about 0.1 to about 2 mm.
11 . The device according to claim 1 , further comprising a guide mechanism which receives the metal particles and applies the metal particles to the rail.
12 . The device according to claim 11 , wherein the guide mechanism comprises a control system that applies the metal particles to the first rail and/or a second rail.
13 . The device according to claim 1 , wherein the roller is harder than the metal particles.
14 . A method of increasing rail traction by applying metal particles to the rail using the device of claim 1 .
15 . A method of increasing rail traction, the method comprising:
a) applying metal particles to a rail; and, b) pressing the metal particles into the rail; whereby the metal particles become embedded into a surface of the rail; and, thereby providing increased traction for train wheels moving over the surface.
15 . The method according to claim 15 , further comprising grinding a metal bar to provide the metal particles.
17 . The method according to claim 15 , wherein the metal particles are harder than the rail.
18 . The method according to claim 17 , wherein the metal particles are selected from the group consisting of tool grade steel, stainless steel, carbide steel and titanium alloys.
19 . The method according to claim 15 , wherein the metal particles range in size from about 0.1 to about 2 mm.
20 . The method according to claim 17 , wherein pressing the metal particles into the rail comprises rolling over the applied metal particles with a roller which is harder than the metal particles.Join the waitlist — get patent alerts
