Applicatioii ar a January 15,1925] Serial No. 2,501.-

This invention relates broadly to fluid pressure o-peratedsanders for applying sand to rails to increase the traction of the wheels of railway locomotivesand the like.

In railway locomotive sanders, particularly of the pneumatic type generally in use, difficulty has. been experienced. in delivering sand to the point-s on the railsfwhere the best results could be obtained. In the sanders known to .us, even though pneumatically operated, a considerable portion of the sand, where a high wind isblowing, failsto reach the rail, because the sand flows principally by gravity throughthesand pipe and tends tofall too slowly from the outlet, and is either blown away-before it reaches the effective points of utilization or diverted so it falls beside the rail head, rather than upon the traction surface of the rail. 7

The primary object of the present invention, isto provide an improved apparatus which will effectively deliver the sand at high velocity in close proximity to the points of contact of wheels and rails, and thus overcome ineffective sanding and its. resultant waste. I

Other objects of the invention are, to provide improved sand .ej ecting means; improved means for extruding the sand from that in the receiving chamber of the trap, which will not become clogged; and, an improved sand trap which is efficient in operation. Other objects of the invention will appear from the detail description. i 1 a The invention consists in the several novel featureshereinafter setforth and more particularly defined by claims at the conclusion hereof' In the drawings: Fig. 1 isa diagrammatic elevation of a steam locomotive equipped with the inventionyFig. 2 is a longitudinal, vertical sectional view of a double sand-trap embodying the invention. Fig. 2* is an enlarged section through the nozzles 'for delivering fluid under pressure into the sand receiving chamber of the trap. Fig. 3 isa'horizontal section of the structure shown in Fig. 2. Fig. 4 is a transverse section taken on' line 4- 1 of Fig. 2. Fig. 5 is a perspective view of asingle sand trap embodying the inven- 7. r 9 is a detail plan of a portion of the double sand trap'shown in Fig. 2.. F ig.-10 is a section on line'1010 of Fig. 2.

The single sand. trap exemplified in Figs. '5 to 8 inclusive usually comprises a cast body B which is provided with transverse holes'h for bolts to secure the trap in position adjacent thejsand dome 8 of the locomotive 9.

A, chamber 10 formed in body B is connected and adapted to receive sand in any suitable manner from the dome 8 through a port 11. The outer end of chamberlO is formed by a removable screw-plug 18,'so access maybe had to said ohamberfor cleaning or other purposes. Body 'B' of the trap is formed with an enlarged portion b in which is formedan upwardly inclined passageway orv duct 14, through which the sand from chamber 10 is lifted. A cylindrical lining15of soft wearresistive metal, such as lead, is provided around the way 14. The axis of passageway 14 is transverse to the axis of chamber 10 and port 11 and is inclined upwardlytherefrom. A. chamber 16, formed in body B, is" provided to receive, through a downwardly extending Y conduit 17 sand from passageway 14. A "removable screw-cap 18, in anopening 19, forms the upper end'ofpassag'eway 14 and conduit 17 and provides access thereto. A liner 20 of soft wear-resisting material, such as lead, is positioned and shaped in said'cap to deflect the rising sand from passagewaylll], downwardly through conduit 17 into chamber 16. The latter h'asan outlet'in its frontside into which is threaded anoutlet pipe-section 22, which is provided with acylindrical wear resisting lining or sleeve 23 of leadjor -the like.' This lining extends from-a point adjacent to one end of said section,toa point ad'- jacent the other end'thereo'f, and isconfined in an internal enlargement orrecess 2 1. In making this section, the metal to li'ormthe liner is poured into the pipe through an inlet 25. I A vent 26 is'provided to permit the ductile metal to'ilow into allpartssof theirecess. "Theemetal in inlet 25 and vent 26 serves to anchor the liner in the pipe section.

A suitable core is placed in the pipe section whilethe liner is beingpoured into it.

tion. Fig.6 is an end elevation of the device zontal sectional view taken on line 8-8 of Fig. I I

A nozzle 27, substantially coaxial with 8 way 14:, is provided to direct a jet of air lon-i gitudinally through said wayl l and lift the sand out of the chamber "10' and force it throughpassageway 14 andconduit 17. into j and, for that purpose, the member" D is formed toserve as anada'ptcr between the: body or casing B and the dome structure, the

the ejector chamber 16. This nozzle 27 is arranged to initially extrudc thesand passing into chamber from the dome and force it through way 14 and conduit 17. into the ejectorchamber. In; practice, it has been .found that'when thenozzle 27 is provided with a small jet opening,large particles of sand Wlll settle lnto such openlng and sometimes become lodged therein with sufiicient security to clog the jet and thus "render the lifting operation inefficient." To overcome this dilhculty, a colnparativelylarge opening 27" (Fig. 7) is formed in the nozzle. A pipe 29 delivers air under pressure into an inlet duct 6 formed in one end of body B. A nozzle 27 in duct 6 has an openingsufliciently I small torestriot andjet the air into a. downwardly extending passageway If in body 13' which has itslower end inclined and in comjmunication with the inlet side of lifting nozzle 27. v The axis of the jet opening in nozzle 27 is longitudinal of the duct 6 As a re sult of employing thenoz'zle 27 with a restricted jet-opening in thesupply conduit, and a liftin 'nozzle 'witha relatively large for the large particles of sand to prevent the delivery of air'inthe desired volume and velocity through chamber 10 and passageway 14,becausetl1e sand cannot reach theopening in nozzle 27 which is elevated for that pur pose. Access may be had to nozzle 27 b for cleaning or replacement through an opening in'the top of body B which isnormally'closed bly a screw-plug 27. Access may be had to tie lower end'of conduit 6 and the inner end i of nozzle 27 through an opening in the body B, which is normallyclosed by a plug 27".

ejector'nozzle 30 is arranged to dis charge a jet of air under pressure axially into and longitudinally of the pipe 22 to project and impel the sand delivered into the ejector-chamber 16 under a high velocity throughout the entire length of the deliverypipe, so that itwill be forcibly projected from the exit of the delivery pipe to the 'pointof contact between the traction-wheel and the rail. In practice, it has been found that the useof ajet 30 in conjunction with a jet" for extruding the sand from the trap. will attain this desired result. Nozzle 30is connected to receive air from a conduit '31 in a member D; ln'practice, llilS desirable, in

some instances, to apply'the present invention to certain existing types of sand domes holes 5 beingextended through the adapter so that the attaching bolts 5 will conjointly secure said bodyand adapter in place] A pipe 32 is adapted to deliver air under pressure into duct 31. 1 Pipe 29, for supplying compressed air to the nozzles 27 and 27 is connected to'said' casing BL This construction, with pipesseparatel supplying air to l the sander and litter and he ejector nozzles,

is adapted for use in instances where separate control of the jets is desired. In Fi s.,1 to 4 inclusive, the invention is exemplified inadouble trapsuitable foruse on a single sand dome for sanding the front or to the'rear of the driving wheels respectively, as may be desired.- The casing B forms two ofthe single traps shown .in Figs.

5 to 8, which arearranged end-to-end and are integrally formed, but relatively reversed, so

that the structure will be compact and may be easily installed. Each t-ra construction will be provi ed with nozzles duit 17 andan ejector :nozzle 30, like those 1 in this double 27 and 27, a chamber 10, passageway 14,0011

describedin the single trap construction.

In this form, of the invention, the adapterD is dispensed with. The outlet of one of the traps is connecte v sand from one oftheejector chambers 16 to delivery pipe. 34 forisanding one' of the rails in front of one of theidrivers35. The pipe-section 22, which leads from the ejector ipe section 22- d to deliver the chamber 16 of the other trap, is connected, to

a delivery'pipe 33, which is adapted'to sand the rail in the rear of one of the drivers or traction-wheels 35. l

In the form of theinvention exemplified in Figs. 1 to 4, the ejector nozzles 30rare'supplied with compressed airfrom" ports 6 to which air isdelivered through pipes-29 respectivel The ductsBlfi-jwhic'h deliver air to thel ejector nozzles, lead from the ports b, respectively, so'that compressed air will be conjointly snpplieduto the lifter and ejector nozzles and so that a single controlling device or valve'will simultaneously controlthe operation of all of, the nozzles in one trap. In this construction,a clean-out plug 31 maybe provided-for each duct31.

d In the construction'shown in Fig. 1, the

pipe 29 is formed as a branch or a pipe 49,

which is connected to a suitablecontroller valve G and which is adapted" to, supply com: pressed airto the front sanders at either side of the dome.

Pipe 29 of' the rear trap in each body B is a branch of a'pipe 50 which is I connected to the controller valve C to supply air under pressure'forthe operation of the rear sander. Pipe 50 is also connected to the corresponding-sander at "the other side of the dome; A .pipe51 supplies compressedair from a suitable'source to the controller valve C, as well understood in theart, a

.The invention" exemplifies animproved sander, in whichprovisio'nis made for cxtrudin'g sand. from the trap with means for projecting sand in sufficient velocity through the delivery pipes to cause the sand to" be reliably delivered in close proximity to the points of contact between the wheels and the rails. The invention also exemplifiesjan improvedpneumatic lifting means for the'sand,

in which provision is made 'to prevent the lifting nozzle from becoming clogged or inoperative. The invention also exemplifies a sander in which provision i'sma'd'e for conjointly supplying sand to the ejector and lifting nozzles so that they maybe unit'arily controlled.

. The invention is not'to be understoodas restricted to the details set fortln-since' these maybe modified withinthe scope of'the apspirit and scope of the invention. 1
