Application May 16, 1947, Serial No. 748,464

11 Claims.

The invention relates to improvements in sandwith a valved nozzle which is adapted to automatically open to supply sand when the nozzle is placed in the opening in the wall of a sand box on a locomotive and is adapted to automatically close as soon as the nozzle is removed from the sand box, thus avoiding wastage and loss of sand.

Another feature of the invention resides in the use of a sealing plate in'connection with the sanding hose which is adapted to seal the opening in the sand box when the vhose is positioned therein.

Another feature of the invention resides in the provision of means for supporting the iiexible hose pipe in such a manner as to prevent sag of the pipe below a slope whichV insures a satisfactory ow of sand.

Another feature resides the improved gate valve mechanism associated with the sanding nozzle.

`While the present device has been particularly designed for use in connection with sanding hose and nozzles intended for servicing locomotives, it will be understood that the invention is of wide application and in its broadest aspect is not confined to this particular use.

The invention will be more readily understood by reference to the accompanying drawings and the following detailed description, in which is set forth by way of illustration a specific embodiment of the invention.

Fig. 1 isa view inelevation with parts in section of the sanding apparatus, dotted lines showing different positions of the hose and nozzle, and a portion of a locomotive wheel upon a track being diagrammatically shown also in dotted lines;

Fig. 2 is a detail section on line 2-2 of Fig. 1 but on a larger scale showing the rotatable attachment of the hose and the sand supply pipe;

Fig. 3 is a sectional view on a larger scale than Fig. 1 of the nozzle applied to a sand box opening, the nozzle valve being shown in open position;

Fig. 4 is a front view of the nozzle showing the sealing plate in full lines and the slide plate in dotted lines;

Fig. 5 is a section on line 5 5 of Fig. 3; and

Fig. 6 is a View similar to Fig. 3 with parts in elevation but showing the nozzle removed from the sand box opening and the valve closed.

Referring to the drawings, A represents a flexible hose pipe for supplying sand to the sand box of a locomotive. The pipe may be of any suitable material and, as shown,- is connected at its upper end by a swivel joint B to a sandsupL ply pipe C supported on an upright post D. By reason of the swivel connection B a single hose pipe may be used to service locomotives standing on two adjacent tracks. t

Adjustably carried by the upright D is a clamp E to which is connected one end of a hose supporting rod Fl` provided with a clamp Gr at its other end adapted to slidably engage the hose A intermediate its ends. As Figo'. 1 indicatesrthe supporting rod F will support thehose when in use at such an angle that sag is eliminated and free flow of sand to the sanding box is insured.

At the lower end of the hose A there is provided a two-part valved nozzle H, which is the subject of the present invention. and which is adapted to be inserted within opening in a locomotive sand box diagrammatially indicated at I. The, nozzle is of Such construction that as. Soon as its end is inserted. in the Sand box opening and rests upon the portion of the Sand box wall beneath the opening, the nozzle valve will be automatically opened to at once supply sand to the sand box, but as soon as the .nozzle is removed frorn the opening the valve will be automatically closed, thereby preventing wastage of sand. Suitable sealing means may be provided in conneotion with the nozzle so that a tight t may be insured between the sand box `opening and the nozzle.

As shown, tne nozzle H consists of two tubular parts I0` and II, With automatically operating valve means connecting the two parts. The upper part IIJ is connected to the hose pipe A by means of a suitable clamp I2. The lower part I l is adapted to be inserted in the opening in the sand box I with its under surface resting on the portion of the sand box wall beneath the opening. l

As shown, the lower nozzle member II is provided with a sealing plate I3 which may be secured to the member Il by any Suitable moans. as by welding or brazing, at I The plane of the sealing plate I3 is preferably at an oblique angle to the central axis of the nozzle portion II to which it is secured, and theplate I3 is pro-` vided with an opening l5 in alignment with the bore of the nozzle member Il. Thus, the plato I3 serves to seal the opening in the sandbox when the nozzle member is inserted therein, :and `also provides a limiting stop for the` nozzlel't will be apparent that the sealing action is aided by the diagonal mounting of the sealing plate. If a tight joint is desired suitable packing means may be provided at the surface of the sealing plate. Such packing means. would render the nozzle iluid tight-so that it could be used for supplying liquid as Vwell as fluent materials such as sand andthe like, for which it is primarily designed.

` The sealing plate I3, together with its opening I5, comprises one member of the automatic valve with which the nozzle H is equipped, the other member comprising a slide plate I6 carried by the upper nozzle member Ill and slidably connected to the sealing plate I3 by any suitable means. As shown, the plates I3 and i6 are maintained in abutting sliding relation by means of guide ilanges I'I carried by the sealing plate I 3. Upward movement of the slide I6 with reference to the sealing plate I3 is limited by a top flange I3 on the sealing plate I3,- and similarly, downward movement of the slide plate is limited by a pair of stops or screws I S, I9 carried by the sealing plate.v The slide plate I6 is provided with an opening 20 which permits passage from the upper portion of the nozzle into the lower portion thereof when the openings 20 and I5 in the plates I5 and I3, respectively, are brought into registry. In accordance with my invention this occurs when the lower nozzle member II is inserted through the opening in the sand box and rests upon the wall portion or ledge below said opening, the weight of the upper nozzle member I I! and the parts rigid therewith causing the slide member I6 to move by gravity to its lowest position limited by the stops I9. The sand may then be allowed to ilow through the nozzle without fear of overow, as when the box is full the sand will pile up in front of the nozzle opening and prevent further flow, thus providing an automatic cut-off which requires no attention from the operator.

When the nozzle H is removed from the opening on the sand box the weight of the outlet nozzle member II and the sealing plate I3 connected thereto causes the sealing plate to move downwardly with reference to the slide plate until the upper end of the slide plate contacts the flange I8 at the upper edge of the sealing plate, in which position the openings I and Z8 are out of registry and further flow of sand through the nozzle H is automatically cut off.

If desired a pivoted, automatically operating member 25 may be provided to latch the valve in both open and closed position, the latch being' held in lock by gravity. It will be seen from the drawings showing the openings in open position (Figs. 3 and 4) that due to the design of these openings when the outlet member I I slides downward relative to the inlet member I il to close the opening a minimum of sand grit can be drawn into the contacting faces near the lower half of the opening and none in the upper half, and when said outlet member slides upward relative to the inlet member to open this opening a minimum of sand grit can be drawn into the contacting faces near either the lower or upper half of the opening due in part to the design and in part to the continued outflow in the outlet end until closure is complete.

From the above description the desirability of a vertical sliding movement of the two valve members with reference to each other will be apparent, the outlet member II moving upward tolopen the valve, and downward to close the va ve.

The invention has been described in dtail f01` 4 the purpose of illustration, but it will be obvious that numerous modiiications and variations may be resorted to without departing from the spirit of the invention.
