TRACK sannnn.
Application filed October 27,1922. Serial Itfil'o. 597,240.
To all whom it may concern:
Be it known that we, RALPH A. LIGHT and JOSEPH W. PRICE, Jr., citizens of the United States of America, and residents of Philadelphia, in the county of Philadelphia. in the State of Pennsylvania, have invented certain new and useful Improvements in Track Sanders, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.
Our invention relates to track sanders used in connection with locomotives and has for its object to provide a sander of simple and efficient construction and in which the air blast nozzle or nozzles provided for lifting the sand out of the trap and delivering it to the delivery passage are at the same time located in such a way as to act with great efficiency on the sand and to be completely protected against the entry of sand into the nozzle or nozzles.
The nature of our improvement Will be best understood as described in connection with the drawing which is a sectional elevation of our improved track sander and in which- 7 A indicates the casing making up the body of the sander and having an opening B at its top through which it is connected with an elevated sand box. Below this opening the casing has formed in it a sand receiving bowl E and a bowl opening G separated from the bowl by an upwardly extending wall portion C and connected with the bowl portion by assage extending over the top of the wal C. e indicates the normal angle of rest of the sand in the bowl portion of the casing. H is an opening in the bottom of the bowl portion normally closed by screw plug I. J is a threaded opening formed throu h the top of the passage F and connectef, as shown, with two nozzle passages J and J the nozzle passage J being directed toward the bowl portion of the' casing and the nozzle passage J bein directed toward the outlet passage G. is the air pipe leading to the opening J and in which, by preference, we place a valve casing L having a port L in connection with which operates an adjustable needle valve M. This valve is entirely distinct from the ordinary controlled valve by which air is admitted and cut oil from the pipe K adapted to receive sand and has for its function to regulate the ressure of air delivery through the pipe to the nozzles J and J 1 In operation the sa'ndtrap has its bowl portion E normally filled with sand up to the level indicated at c. When it is desired to deliver sand to the track, air is turned on through the pipe K and a jet of air is delivered through the nozzle J directly against the sand in the bowl with the result of picking up the sand and, through an eddying action, carrying it through the passage F and delivering it to the outlet passage G. This action is improved and accelerated by providing the secondair nozzle J 2 directed into the outlet passage G.
It is a marked feature of our improved construction that the air nozzles are located in the passage F and entirely outside of the bowl portion in which the sand is normally retained. There is, consequently, no liability of the sand getting into the nozzles way.
sand is normally retained, a discharge opening separated from the bowl by an upward- 1 extending wall and a passage connecting tlie bowl and discharge opening o er the wall, in combination with a blast nozzle located in the connecting passage above the normal sand level therein and directed toward the bowl portion of the trap.
2. A track sander comprising a trapsand box and having a sand is normally retained, a discharge opening separated from the bowl by an upwardly extending wall and a passage connecting the bowl and discharge opening over the wall,in combination with a blast nozzle located in the connecting passage above the normal sand level therein and directed toward the bowl portion of the trap and a second blast nozzle also located in the passage and directed toward the discharge opening.
3. A track sander comprising a trap and desire to secure by gravity from a bowl wherein the I :rn, or PHILADELPHIA, PENNSYLVANIA, As-- adapted to receive sand by gravity from a sand box and having a bowl wherein the sand is normally retained, a discharge opening separated from the bowl by an upwardly extending wall and a passage connecting the bowl and discharge opening over the wall, in combination with a blast nozzle located in the connecting passage above the normalsand level therein and directed toward the bowl portion of the trap and an adjustable needle valve controlling the flow of air to the nozzle.
