TRACK-SANDING APPARATUS'.

SPECIFICATION forming part of Letters Patent No. 704,284, dated July 15, 1902.

Application led April 26, 1902.

To a/ZZ whom, t may concern; y

Be it known that I, JOHN J. DYoLAN, J r., a citizen of the United States, residing-"at Baltimore, State of Maryland, have invented certain new and useful Improvementsiu Track- Sanding Apparatus, of Which'the following is a specification. y

This invention. relates to track-sandin g apparatus of that class Yin which the discharge of sand from the sand-hoxis effected by duidpressure, such as air or steam.'

The object of the invention is to provide a construction of sanding apparatnswhereby the casing containing the air-nozzle may be readily disconnected and Withdrawn from the..

sand-box for. the purpose of repairs or the like Without danger of Wasting the sand.

The invention consists of certain constructions,arran genients,and combinations of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in Which- Figure l is a horizontal sectional View of a locomotive sand-bor; provided with the improved track-sanding apparatus oflmy in-` vention, the directionrof the front oi the loco'- motive being indicated by the arrow x. Fig. 2 is an enlarged vertical longitudinal section illustrating` one of the-Sanders.' Fig; 3`isa` horizontal sectional view of a sandercasing, taken on the line 3 3 of Fig.` 2 and looking ink the direction of the arrow in saidgure. Fig. 1 4L isa detail perspective'view of a shield hereinafter described.'

Referring to the drawings, theletterAdesignates a locomotive sand-box provided at itsVv front and back (considered with respect to the locomotive) with two diarnetrically opposite discharge-openings a. To the inside Wall of said sand-box A and surroundingleachof the dischargeopenings d are ,securedtwo shields B, eac-h of which comprises a'platc l), rigidly secured to the sand-box, and an in- Hardly-extending sleeve c, Whose inner edge is formed with a downward]y-facingbeveld, as indicated in Figs. 2 ande, andeachplate b is provided with an interiorly threaded opening e, as indicated in Figs. l and 2. In the said threaded opening e of each plate h (see Figs. l'a'ndQ) is secured a horizontallyextending casing C, provided With an eXteriorly-screW-threaded portion f, engaging the serai No'. 104.768. on, man.)

screw-thread of the said plate-opening and I prevented from accidentally'nnscrewing by means of a lock-n ut f and said casing is also provided with an arm Q projecting into the sleeve c of the shield B and having an up- Wardly-facin g beveledinner end h. Both` the said casingy and its projecting arm are tubular. The said two casings ,C extend in a horizontal .direction out from the front and back of the sand-box, and each casing is further provided at its outer end with two diverging branches ,forming a Y construction and con-l f Fig. 3, in a direction in alinement With the bore ofthe two branches,res`pectively, and

aipipe jm (leading from'A the source of iiuidpressure supply, which is controlled by the ,engineervin vthe calc l'isconnected by a swivel- '.nntnto'said nipple,so'that a blast of air or steam blown through said outwardly-def iiectednozzles Zwill suck or draw out the sand in the box A through the tubular arm g and casing C, whence the sand will be con veyed by the branches and pipes j or j to the track-rails.

Itis often necessary to unscrevv` the casings Gland draw the tubular arms g out of the ,sand-box in order to remove any obstructions that might have found their Way into the sand-passage or for other reasons, and for this contingency, so that the sand may not flow out andbe Wasted When the casings are disconnected frornfthe box, I have provided the l-i'mfoshields B, whosesleeves o surround the Vtubular armsg'of the casings.

By this construction and arrangement when the tubular arms are drawn out ofthe sleeve in the operation of disconnecting the casings from the sand-box the said sleeves will eftectually pre IOO vent any wasting of sand from the box. The

downwardly-facing bevel of the inner end of the said sleeves provides that the sand sucked out will be drawn from the bottom of the box and at the same time causes the sleeve to present to the sand a longer surface on its upper side than it would if its entrant-opening for the sand were not so beveled, thereby more effectually preventing the sand from falling into said opening, whence it might waste out of the discharge-opening of the box.

The casings C, as is evident, may be readily withdrawn from time to time and inspected to see whether or not they are becoming worn.

While the accompanying drawings illustrate the casings C with two branches fi, it is to be understood that the invention is not limited to such construction, but that each casing may have one straight-away passage from end to end, and it is also to be understood that other changes may be made in the construction and arrangement of parts without departing from the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a track-sanding apparatus, the combination with a sand-box having a dischargeopening, of a tubular casing detachably secured to the sand-box at said discharge-opening and provided with a fluid-pressure nozzle; and a shield provided with a sleeve extending inwardly from said discharge-opening, whereby said casing may be detached from the sand-box Without danger of wasting the sand from the same, as set forth.

2. In a track-sanding apparatus, the combination with a sand-box having a dischargeopening, of a tubular casing secured in said opening and extending outwardly therefrom and provided with a tubular arm projecting into the sand-box; a nozzle for fluid-pressure adapted to discharge the sand through said arm and casing; and a sleeve sui-rounding said arm on the inside of the sand-box, as and for the purpose set forth.

3. The combination of a sand-box provided with a discharge-opening; a shield secured on the inside of the sand-box at said dischargeopening and comprising an inwardly-extending sleeve provided with a downwardly-facin g beveled end; and a sand-discharging apparatus provided with a tubular arm mounted in said sleeve, as and for the purpose set forth.

` 4. In a track-sanding apparatus, a sandbox provided with a discharge-opening, and a shield secured on its inside at'said opening and having an inwardlyextending sleeve adapted to receive a sand-discharging tube, as set forth.

5. A track-sanding apparatus, comprising a sand-box provided with a discharge-opening; a tubular casing in said discharge-opening and projecting outwardly therefrom and provided at its outer end with two diverging branches adapted for attachment to sandtubes intended to lead to the track-rails; and

Vair or steam nozzles extending into said cas- JOHN J. DOLAN, JR.
