Abstract
I have invented a metal heated sand nozzle that keeps sand flowing from the locomotive to the rail in all weather conditions.
In the railway industry, locomotives experience wheel slip problems when pulling heavy freight trains up steep hills in winter conditions when ice and snow covers the rail. The steel drive wheels of the locomotive slip or spin against the steel rails due to poor adhesion. It is common for locomotives to have sand dispensing equipment that pours sand on the rail where the locomotive drive wheels meet the rail. The sand between the drive wheel and rail produces a high friction area where the locomotive can gain traction. However, in winter conditions, rubber sand nozzles that are presently used tend to plug up with ice and snow stopping the flow of sand to the rail. Heated sand nozzles eliminates ice and snow plugging the sand nozzle tip.

Description
Description My invention uses a metal sand nozzle with a 75 volt electric strip heat element attached to the metal nozzle. Snow and ice cannot build up on the sand nozzle tip due to the heat applied by the electric strip heater.
In the drawings which illustrate the metal heated sand nozzle, Figure 1 is a side view of the separate components in the assembly.
1 is the metal nozzle body.

1 is the metal nozzle body.
2 is the bolt which fastens the sand nozzle to the locomotive main sand hose.
3 is the electric strip heater.
4 are the terminal posts on the strip heater where the electrical wire connections made.
is a circular hose clamp that is used to fasten the strip heater to the metal body of sand nozzle.
Figure 2 is a top view of the body of the sand nozzle only. T'he flat surface 6 on top of the nozzle is where the strip sits and lies flush against the body of the nozzle allowing heat to transfer easily to the metal structure. This heat transfer is what will keep the sand nozzle body warm not allowing snow or ice to adhere to the nozzle dispensing tip.
Figure 3 shows the sand nozzle in the fully assembled state. The strip heater 3 is held securely against the nozzle body 1 by the hose clamp 5.
Figure 4 represents a typical set up of a locomotive sand dispensing assembly.
1 is the metal sand nozzle, 10 is the hose where sand flows from the locomotive sand box through to 1 sand nozzle. In Figure 4 you can see the sand particles being dispensed out of the sand nozzle 1 onto the rail 8 where the locomotive wheel 7 will proceed over the sand covered rail.
In Figure 1 the nozzle 1 is what I have designed and built along with fastening bolt 2. The strip heater 3 and hose clamp 5 are commercially built products which are procured and attached to the nozzle 1 to form a completed heated sand nozzle assembly.
The dimensions of the metal nozzle body will vary depending on what type of locomotive the sand nozzle is applied to. Typical body size will be 21.Scm long made out of schedule 40 steel tubing 4.2cm in diameter. The round steel tubing is then fabricated and formed to have a flat surface on one side for the strip heater to sit against as shown in Figure 2, area 6. Sand is dispensed out of flattened nozzle area 11 in Figure l, Figure 2 and Figure 3.
