TRACK-SANDER.

Specification of Letters Patent.

Patented May 7, 1918.

Application filed September 13, 1917. Serial No. 191,097.

T0 aZZ whom it may concern Be it known that I, JOHN H. HANLON, a citizen ofthe United States, residing at Somerville, county of Middlesex State of Massachusetts, have invented a certainnew and useful Improvement in Track-Sanders, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object an improvement in track sanders for use on locomotives and relates particularly to a so called outside sander which is applied to the outside of a sand box. It has been found in'the past that outside sanders are advantageous because they are accessible in case repair work is necessary. For this and other reasons a large demand has arisen .forthem, and consequently, many locomotive sand boxes are cast with a base towhich the outside sander may be attached. Outside sand-- ers as heretofore constructed wear out rapidly and frequently do not deliver sand enough to the rails; furthermore, their con struction is such that theycannot be properly regulated and the amount of sand delivered to the wheels is often not under proper control.

The object of my present invention is to overcome these difficulties and to provide a sander which will feed an increased amount ofsand tothe wheels .of thelocomotive and which may be controlled. by the engineer so that any given quantity of sand may be ap plied to'the rails. The sander embodying my invention isa combination gravity feed and air blast sander. It. is so constructed that a direct flow of sand is P ovided and the force of the air blast is not cut down, so that the sand may be driven through the sand pipe a sufficient distance to deliver sand to any of the drivers with enough force to insure its being delivered to the rails. Ow-

mg to the flow of the sand directly into the sand pipe, 'themetal casting is worn away by the action of the sand much less rapidly than has heretofore been .the'case, and will last for a greatlength of time without needing to be renewed. No lead bushings or caps which must be replaced at frequent intervals are required, thus greatly increasing the economy of operation. Furthermore,

- the see is r ile w eri t e e readily attached to the usual base with which the sand box is provided, and may be equipped with any desired number of sand nozzles, so that as many nozzles as needed may be used on any type of locomotive with the use of a single sand boX.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Figure 1 is an elevation of a sand box located on a locomotive boiler and provided with a device embodying my invention, a portion only of the 'boilershell being shown.

Fig. 2 is an enlarged view partly in section of a track sander embodying my invention which is provided with four sand blast nozzles.

Fig. 3 is a view similar to Fig. 2, showing a1 sander provided with two sand blast. noz- 2 es.

Fig. l is a section on line 4 i of Fig. 3.

Having reference to Fig. 1 of the drawings, at-A is shown a portion of the upper surface of a locomotive boiler upon which is mounted a sand box B of any usual construction. The sand boXv B has the usual base and is provided at two oppositesides with bosses G of any usual form, to which the sanders D, embodying my invention, are secured in the customary manner. The sanders D are particularly intended for use on locomotives having sand boxes of the present well known construction and are applicable to them without. any change whatsoever.

-The sander D is a combination gravity and air blast sander, as is the case with the usual outside sander, and for this purpose is provided with a pair. of gravity feed-openings 11 and 12 and a pairiof sand inlet passages 13, only one of which is shown as seen in Fig. 2, through which the sand ejected by the air jets is supplied. Thesander casting D consists of azface plate 15, having bolt holes 16 by which it may be secured to the sand box boss C in the usual manner,.the gravity feed. openings 11 and 12- and the sand inlet passages 13 being arranged to co in w hi ea spqad eg passage through wheels in the usual manner. the flow of sand being controlled by gates or sand valves of any well known form, located within the sand box and not shown in the drawings.

The sander l) is also provided with air blastnozzles. one of which is contained in each of the arms 1'? and 18. These at as are similar in their construction and therefore the arm 17 will be referred to only. The arm 1? inclines downwarr v as shown in Fig.1. The sand inlet pa......ge 13 ther in receives sand from the sand box by gravity. T he passage 13 extends through the arm 17, and may be closed by a plug 21. as shown in Fig. 3, or connected with anoth sand blast nozzle as shown in Fig. 2. as will be herein-.

it one side of the arm is a horizontal passng which is threaded to receive a pi e z Directly opposite the passage 22 is an air blast nozzle Z-l having a longitudinal passage 25 extending through it. and forming an air d cha orifice. There is preferably also a tra are a 26 which intersects the passage and is located. near the inner end ot the nozzle. An air chamber 2. formed in the wall of the arm 17 and is closed at one side by a. threaded plug having a recess in its inner face. The nozzle extends through the wall between the s. :id inlet passage 13 and the air chamber '2'? and its inner end located in the recess in the plug At the upper ad of the chamber 27 i port 30 to which is secured a pipe 31 Fig. 1) adapted to supply compressed air and controlled by an engineefs cal) valve. not shown, in the usual manner. The air from the port 30 is directed. down through the chamber 27 toward a well extending through the lower end of the arm 1? and closed by a screw nlu The well 32 is thus arranged so thi after described.

it will catch all the sediment, scale and lilre'dirtbrought in with the air. llt may be readily cleaned out by removing the plug The nozzle is horizontally disposed and is so arranged that the passages at its inner end are within the recess in the plug 28 and are protected by it. In the past, great ditiiculty has been experienced owing to the tendency of air nozzles to become COIIIPlGtGlf plugged with air sediment and the like so that no sand will be discharged through the sand discharge pipe without ,eeami taking the sander apart and cleaning the air nozzle. Although attempts have been made to prevent this, the diiliculty has not been entirely overcome. The construction *ein disclosed is especially designed to iedy this trouble. The inner ends of the air passages 25. 26 in the nozzles are located completely within the recess in the plug :28 so that the air which is directed downwardly from the. port 30 toward the well 32 passes by the inner end of the air ges and deposits the sediment and the like in the well 32 before it enters the paslf the passage 25. in the air nozzle becomes plugged, it may be readily cleaned out b removing the plug '28 and passing a wire directly through the nozzle. This can be done quickly and w thout loss of sand; neither is any special tool necessary.

The arrangement of the nozzle 24- in the sand chamber 1 3 also an important teature of n'ry invention. its is well known to those s ed in the art, there is a tendency for the chi ssage in the nozzle to wear so that the passage becomes larger than desired and more air than required passes through it. In outside combination sanders i.i l1(?1'lOfOl constructed, so far as known to me, the air nozzle has of necessity been inclined upwardly and the sand particles striking against the end of the air passage hare a tendency to wear it away at the In the device embodying my invention the horizontal arrangement of the nozzle prevents the end from being hit by the and particles which in the old construction re blown up by the air blast and dropped down on the nozzle end. In this way the air pass- 0 does not become enlarged. This is important for l have found that the varying sizes of air passages in sanders arranged at each side of the sand box so varies the amount or sand fed, that in many cases pra tically all the traction is obtained by the dri on one side of the locomotive, with the l'Q:-.llll' that. one set of drivers has a tendency to slip and to rack the locomotive parts.

ln order that the sand chamber 13 may be cleaned out it it becomes plugged with pebble or stones contained in the sand an o; hing is provided on the upper inclined s face of he arms 17 and 18 which is closed by a threaded plug 10 as shown in Fig. l. This renders it possible to get at the chamber and remove any obstacle that may be "entering with the operation of the clerics. and without loss of sand through the clear. out openin By the arrangement and construction shown herein, I am enabled to provide combination gravity and force feed sanders which do not receive any wear from the sand blast and therefore will last indefinitely. The air nozzle propels the sand directly into the sand pipe 23 through which it is conveyed to the wheels without any resistancesave that which is occasioned by the walls of the pipe. The necessity of replacing sander castings or of providing lead bushings is thus done away with.

A further important feature of this construction is that the amount of sand supplied by the blast nozzle is'greatly increased for the full force of the air is obtained and the maximum amount of sand is conveyed by it. In the construction heretoforeem ployed, the resistance occasioned by thearrangement of the sander passage is very great so that the force of the air blast is ma terially diminished and accordingly the amount of sand conveyed is decreased to a marked degree Furthermore, the resistance prevents the flow of sand from being properly regulated, whereas in the construction herein described, the flow of sand may be regulated so that the desired quantity of sand may be supplied to the wheels. This is important, for without proper regulation the engineer cannot control the traction of the drivers on each side of the locomotive, which should be substantially the same for otherwise great stress and strain is placed upon the locomotive parts.

The sander embodying my invention is arranged to supply sand from a single sand box to as many drivers of the locomotive as is desired. The construction of the sander nozzles by which a direct/flow to the sand pipes is provided, affords suflicient force to propel the sand to any point on the engine without danger of clogging the sand pipes. Furthermore, each sander may be equipped with as many sander nozzles as are required, so that all the drivers of any type of locomotive may be supplied. In Fig. 2 of the drawings, my improved sander is shown as provided with four sand blast nozzles. Mfore may be added if desired. The sand inlet passage 18 extends through the arm 17 and is directly connected with a passage 52 in a sander member 51 by means of a nipple 50. In the device shown in Fig. 2, the passage 52 is closed by a plug 53 but if more sander members should be desired, an additional sander member could be attached by replacing the plug 53 by another nipple 50.

The sander members 51, only one of which is shown in section in Fig. 2, are provided with an air blast nozzle 56 which is similar to the air blast nozzle 24 in the members l7 and 18, and is arranged to propel the sand directly into a pipe 55. The sand pipes are entirely separate from the gravity feed pipes and may be projected along the boiler of the locomotive as desired, in order to deliver sand to the drivers. This construction is an important improvement over sanders as heretofore constructed so far as known to me, for I am enabled to m vide as many nozzles as I desire and to propel the sand the required distance so that all the drivers on both sides of the locomotive may be supplied by the use of one pair of sanders and a single sand box.
