Abstract
Description
- This invention relates to a particulate delivery system for a locomotive, and more particularly to a particulate delivery system including a particulate guide.
- Locomotive on-board particulate delivery systems have been used to deposit sand or another particulate onto the leading edge of a rail in front of the locomotive engine drive wheels to provide improved traction under a variety of circumstances. Typically, these systems have included a sand reservoir such as a storage bin filled with sand and constructed or arranged to either manually or automatically charge sand into a conduit, such as a flexible hose, that is connected to the sand bin at one end. A nozzle is usually attached to a second end of the hose. The nozzle is generally tubular shaped, having a through hole formed therethrough with one end of the nozzle receiving the hose and the other end having a round discharge opening for depositing sand onto a railroad track at a location immediately in front of the engine drive wheels.
- These prior systems had a number of shortcomings. Typically, the nozzle was attached to the hose in a manner that made it difficult to adjust the positioning of the nozzle discharge opening to take in to account varying environmental and operating conditions. As a result, a substantial amount of sand would be discharged through the nozzle. Often, the discharged sand would have a wide path, with a substantial amount of the sand missing the rail. Further, the sand would be discharged at a relatively high velocity, resulting in the sand ricocheting off the rail. As a result, the storage bins were often quite large, taking up a substantial amount of room, and were very heavy.
- Another problem associated with these prior art particulate delivery systems is that moisture could easily enter the discharge opening of the nozzle. As a result, sand would stick to the wet surfaces of the hose and the nozzle, causing blockages. Further, if moisture entered the discharge opening of the nozzle, it would often freeze and block the particulate delivery system. Another problem associated with these prior particulate delivery systems is that wind could blow the sand exiting the nozzle discharge opening, causing the sand to totally miss the rail.
- The present invention overcomes some of the deficiencies of the prior art and provides alternatives and advantages thereto.
- The present invention includes a particulate delivery system that deposits a particulate, such as sand, onto a locomotive rail in a more precise and accurate manner and using substantially less particulate. The particulate delivery system prevents or dramatically reduces the impact of wind on the discharged sand, resulting in a higher percentage of the sand being accurately deposited on the rail. The system also drastically reduces the frequency of blockages due to moisture or freezing.
- One embodiment of the invention includes particulate delivery plumbing having a body portion and a through hole formed therethrough. A particulate charge inlet opening is provided at one end of the body portion and an outlet opening at a second end. A pair of spaced-apart protective guide members extend from the body portion at the second end of the plumbing and straddle the particulate outlet opening. Each of the protective guide members may have a wall with a first end attached to the body portion and a second free end. Each wall has an inner face extending from the body portion to the free end to define a slot between the inner faces of the protective guide members. The inner faces may include first portions that are parallel to each other and second portions that are tapered toward each other. The particulate delivery plumbing may include a hose, a nozzle and a particulate guide. Preferably, the nozzle is connected to one end of the hose and a particulate guide connected to the nozzle. The hose, nozzle and particulate guide may be separate pieces that are connected together, or the particulate delivery plumbing may be a single continuous integral piece of material.
- The particulate delivery plumbing system may include a nozzle having a body portion and a through hole formed therethrough to provide a particulate charging inlet opening at a first end and a particulate outlet opening at a second end. The body portion of the nozzle may include an outer surface having a first locking feature. The first locking feature may be a slot formed in the outer surface of the nozzle body portion. A particulate guide is provided having a body portion with a through hole formed therethrough to provide a particulate charging inlet opening at a first end and a particulate outlet opening at a second end, and a pair of spaced-apart protective guide members extending from the body portion at the second end and straddling the particulate outlet opening of the guide member. These spaced-apart protective guide members define a slot therebetween for discharging particulate from the particulate discharge plumbing system onto a locomotive rail. Preferably, the particulate guide includes an inner wall defining the through hole formed in the body portion of the particulate guide. The particulate guide inner wall may include a second locking feature matable with the first locking feature on the nozzle to releasably lock the particulate guide and the nozzle together. The second locking feature may be a rib formed on the inner wall and extending inwardly into the through hole cavity. The particulate guide is constructed and arranged to receive a portion of the nozzle so that the rib extending from the inner wall is received in the slot formed in the outer surface of the body portion of the nozzle to connect the nozzle and the particulate guide together. The nozzle may include a plurality of slots formed in the outer surface constructed and arranged so that the particulate guide may be adjustably connected to the nozzle so that the rib may be received in any one of the slots as desired to adjust the position of the guide. Preferably, the protective guide members of the particulate guide include a wall having a first end attached to the body portion of the particulate guide and a second free end. The wall includes an inner face extending from the body portion of the particulate guide to the free end so that a slot is provided between the inner faces of the protective guide members. Preferably, each of the inner faces of the wall includes a first portion and a second portion. The first portions of the inner faces are parallel to each other, and the second portions of the inner faces are tapered toward each other.
