To all @hom it may concern: y

Be 1t known that I, HARRY VIssEnING, a

citizen of the United States', and a resident OfChicago, in the county of Gool; and State of Illinois, have invented certain new and useful Improvements in Traps for Sander Devices, of which the following is a speciication. i. v

My present invention relates especially to sanding apparatus for v locomotives and more particularly to ldevicesof thisvclass yn the operation of which air or otherxfluid pressure is employable ratherthan gravity alone.

Ihis invention contemplates the provision of an improved sand trap,l and improved Huid pressure delivery connections lfor such trap for use in connection.withfsanding apparatus.

The primary objectscof my invention are the provision of a trap so improved and constructed as to be less susceptible to the grinding actionv o-iithewhirling sand blast on the interior ofthe trap and so of substantially longer life inservice, whereby the cost and inconvenience of replacement and repair may be saved; the provision of a trap thaving an improved arrangement oi passages and .connections whereby the whirling motion of the sand is largely overcome, and the passage Ofsandtherefrom, obstructing and injuring the apparatus and rendering it less eiiicient, if not'inoperative, is avoided; vthe provision `of means lwhereby the wearing parts may be readilyrrenewed if necessary; and the provision ofrmeans-j whereby the trap may be readily cleaned.

VMy invention also has for its objectsthe provision of an improvedmethod oi' form'- ing the resistant lining above referred to by pouring molten metal around temporary cores inserted into the trap,` together with other objects which will be ,hereinafter de lined. y

In the attainment of thefobjects stated as well as certain further advantages to belbef low disclosed, I have provided theyconstruction illustrated in the accompanying drav ings, wherein- ;v n

Figure 1 is a skeleton outline of-a side elevation of a steam railway engine or locomotive, equipped with a track sanding' device employing my improvements; Fig. 2 is an enlarged perspective view. ofthe ex.-

terior of the sandbox and ytrap ofFig. 1 andthe operative connections therefor, illustrating'ithe manner in `which the trap is supported by `Jthe sand box of the locomotive;

resistant lining in said trap, Fig. `4 being taken on the linel IV-IV of Fig. 5, and Fig. 5 being taken 4on the line V-V` of Figt. c Y 1 W Referring now more particularly to Figs.

1 and 2 of the drawing, it willbe observed that I here yillustratie diagrammatically the application of my invention, which though ofutility elsewhere I nd peculiarly available in connection with the present general design of track. sander construction. [This comprises as here showna compressed air reservoir, 10, from which a conduit pipe 11 leads to the engineers cab where ai controlling valve 12 kis .operable to adniitfthe passage of `the air supply through the conduit 18y leading to the sand trap 14 and by abranch 15, tothe interior of the sand box 16, a .delivery pipe 17 leading from said trap 14 to the ejector device 18 arranged adjacent the point'of contactlof the driver wheelwith the rail. The trap14 is attached .to the sand boxby` bolts 19 passed through the holes, 2O and short delivery pipes 21, 22 arek inserted in said inlets at the ends. or' the passages 28 and Q4. The pipe 21 is normally open ktoward the interiorl of the sand box 16 for the influx 'of sand*v into the trap v14,' but the pipeQQ is normally closed by a valve 25 having projecting arms 26 for breaking up the sand should it fbethrough a hand lever with an extensionrofd 27, said valve 25, being mounted at one end come caked `or compacted inthe box,-16. e

The valve 25 is operable from the ca b-l0v n ofy a -rocking lever supported upon a bar, i.

28,' the opposite .end of said rocking lever vconnectedy l -A The body of the trap 14 is provided with a passage 23 open Vat both sides ofthe body for a purpose to be below described and suitable connections at the outlet 24 to receive the said delivery pipe 17, and at the inlet 31 to receive the fluid pressure supply pipeA 13. Communicating with. the inlet 31 by the passage 32 is a secondary trap or chamber 33 open at the top but normally closed from the atmosphere by a plug 34 and communicating with the sand inlet 23 by means of a nozzle 35 threaded into a passage 52 (Fig. 5). l

It is generally understood by those versed in the operation and care of apparatus to which my invention relates, that traps for sander devices of the character referred to herein have required much care, continual repairs and repeated replacement, and there.- forehave been unavoidably expensive in ythis that firstly, owing to the whirling and grinding action of the sand entering the trap from the connection 21, when acted upon by the blast of compressedair from the connection 31 as heretofore arranged, and a backward suction upon closing the controlling valve 12 tending to draw sand into the pipe 13, the sand rapidly wears away the air nozzle 35, enlarging and rendering unsymmetrical the orifice thereof, 4lessening elliciency of the device in operation and by permitting undue admission of air causing unnecessary expense, drain of the air supply, and load on the air compressor; and, secondly, when the sander is at rest, sand from the connection 21, by reason of the arring sustained by the engine while running, sifts into the pipe 13, thence to the valve 12 and at length through the tank into the compresscr in pneumatically operated apparatus, or into the boiler in steam operated sanders, by virtue of the circumstance that the connection 21 is usually level with or below the nozzle 35.

For the purposeof overcoming the disadvantages above specified and attaining ceri tain further benelits, I have provided the passage 36 and 3GEL with an insert compris# ing upper and lower' portions 37, 37a, prei'- erably filling the cored body portion 38 of the trap, such insert being ofcomparatively soft material which is not so susceptible to the abrasive action of the sand blast, as is the relatively hard metal of the body ofthe trap 14. ln practice l have found that lead is the material best adapted for the purpose ,stated,i.though rubber of varying composiant materials may be used advantageously and are compiisedwithin the spirit of my invention and intended to be covered by my claims. The use ofthe soft metal `lining referred. to accomplishes the desired object of tending to overcome the wearing action of the blast on the passage 38 andnozzle 35 and to eliminatethe whirling motion of such sand, dueto the fact that the Vsoft metal lining roughens in raisedpoints rather than in grooves under the action of the sand. The

ieinovable'cap 39 is likewise provided on its interior face with an insert 35%L having dovetailed connection therewith and where desirable the passage 40 may likewise be provided with a lining made accordingto my present Amethod as below described or one in the form of an inserted pipe as illustrated in my copending application for Letters Patent No. 491,945.

stead of mounting it in axial alinement with the passage 36 as has heretofore been the customary mode of construction wherein the air blast instead of impinging upon the mass of sand blows through it. From further inspection of F ig. 3, it will be observed that in my present invention the nozzle 35 is inserted with the relatively large end 41 of the passage 42 toward the sand supply and the relatively small end of such discharge directed toward the air supply con-l nection. By this arrangement and location of the nozzle 35 I find that two primary advantages `in addition to those above pointed out are attained; irst, owing to the expansion of thek air as it passes from the smaller part `43 of the passage 42 into the larger part 41 thereof a large part of the rebounding'action of the sandis eliminated and consequently the minimum wear of the nozzle 35 takes place; and, second, that since the air supply4 is not used to overcome the inertia of a considerable weight of sand accumulated upon thepdischarge passage, it moves the sand with much greater rapidity, or, in

other words, the actuation of the device and hence the application ofsand to the rails is materially accelerated and ra materially smaller quantity of air is used. The screw plugs 34, 38, and 44, the latter one closing the passage 23m-which an additional sand delivery pipe may be attached if desired, are tions'and other somewhat yieldingly resistprovided not only for the purpose of inserting the nozzle, lining, etc., in place but also to facilitate the cleaning of the trap should sand .become compacted therein.

Referring nowv more particularly to Figs. 4 and 5 it will be observed that l here -illustrate a method of forming invportion 33 of thev trap body 14, the lining 37 having a passage 36,.which.consists in inserting a taperedqcore plug 45 in the opening 46 kott the passage.` 23, such plug 45 khaving ycut out portion indicated in dotted lines'at47f, (Fig. a 4), adapted to receive theend indicatedby the dotted `lines at 48 (Fig. 5) of a tapered cere plug 49 inserted in the opening 50 which` in service is closed bythe cap 39. The passages 40 yand 52 being dannned in any suitable manner, moltenmetalis then poured around the core vblock 49 untilythe v skilled in the art to which my invention pertains without further explanation.
