TRACK-SANDING DEVICE.
serias.
To all 'whom it may concern.'
Be it known that I JOHN GAPP, of Scranton, in the county of Laclrawanna and State of Pennsylvania, have invented a certain new and useful Improvement in Track- Sanding Devices, of which improvement the following is a specification.
My present invention is an improvement upon that for which Letters Patent of the United States No. 950,531, were granted and issued to me under date of March 1, 1910, and its object is to provide a combined nozzle and shut off plug, the nozzle of which may be replaced by a new one when worn or damaged, without requiring the renewal of the entire member, and a sand delivery chamber which may be readily cleared when clogged and which will also act as a carrier for a gravity sand discharge pipe if desired.
The improvement claimed is hereinafter fully set forth.
In the accompanying drawing: Figure 1 is a vertical longitudinal central section through a track sanding device illustrating an embodiment of my invention; Fig. 2, a view, partly in side elevation and partly in longitudinal central section, showing a structural modification; Fig. 3, a vertical transverse section, on the line a a of Fig. 1; and, Fig. 4, a view, partly in elevation and partly in section, and on an enlarged scale, of the shut off plug and nozzle, detached.
As in Letters Patent No. 950,531 aforesaid, the sand receiving chamber, 1, is a hollow or tubular casting, having a flange, 1a, at its upper end, which is secured to the bottoni plate, 2, of a locomotive sand box, by bolts, 3, and nuts, 3a, in such position that the open ltop of the chamber registers with a sand discharge opening, 2a, in the sand box. The bottom of the sand receiving chamber is closed by a removable cleaning plug, 1b. An air chamber, fl, is formed on one side of the body of the sand receiving chamber, to which air under pressure is admitted when the dis charge of sand is desired, through an air supply pipe, 5, leading into an opening, da, in the wall of the air chamber. The bottom of the air chamber is closed by a removable plug, 6, through which a central passage, 6a,
of small diameter, is formed, for the discharge of water or other liquid that may be 'drawn into the air chamber.
A sand delivery chamber, 7, formed in an integral casting, is secured removably to the sand receiving chamber, 1, on the side there- Speccation of Letters Patent.
Application filed December 1, 1910.

serial No. 595,116.
of opposite the air chamber, 4, and under my present invention, the horizontal portion of its body, which is externally threaded, adjoining its inner end, to engage an inter nally threaded lateral nozzle, 1, on the sand receiving chamber, is extended to, or adja cent to, the opposite wall thereof, so as to form a conduit, which is U shaped at its outer end, from the air supply nozzle hereinafter described, to a vert-ical discharge nozzle, 7 a, at the outer end of the sand delivery chamber, to which the sand discharge pipe, 8, is connected, a sand checking wall, 7b, being, as in Patent No. 950,581, interposed between the open upper end of the said pipe and the inner portion of the chamber. Openings, 7e, are formed in the wall of the said delivery chambers, substantially in line with the aXis of the sand receiving chamber, for the admission of sand from the latter to the former, and to admit of the insertion of a rod for clearing out any accumulation of solid matter from the sand receiving chamber, when the plug, 1b, is withdrawn for this purpose. A cleaning opening, 7 C, is formed in the top of the sand delivery chamber, said opening being located in position to aiiord access to both sides of the sand checking wall, 7b, and therefore to both limbs of the U shaped conduit, and being, in the construction shown in Fig. 1, closed by a removable plug, 71. By the removal of said plug, and the insertion of a rod, the chamber may be cleared of any accumulation of sand that may collect and become hardened into a mass within it.
Fig. 2 illustrates a structural modification, in which the cleaning opening, 7c, serves the additional purpose of enabling a separate gravity discharge pipe to be dispensed with. 1n this case, the opening is not threaded to receive a plug, but is adapted to receive the lower end portion of a connecting tube, S), which is screwed into an opening in the upper flange, 1, of the device, immediately below a sand discharge opening, 2b, in the sand box, which is controlled by a hand operated valve. When said valve is moved away from the opening, the sand will be discharged by gravity, through tlie tube, 9, into and through the sand discharge pipe, 8. lhen it is desired to remove or to clear out the sand delivery chamber, the connecting tube, 9, is screwed up sufficiently far to clear the opening, 7C, when the entire sand delivery chamber may be removed from the sand chamber, or a rod may be inserted for clearing out the delivery chamber, as in t-he instance shown in Fig. l.
The air chamber, 4, communicates, by a port, Llc, with a port, lb, the inner end of which is open to the sand delivery chamber, 7. The port, tb, is controlled by a plug, 10, in which there is detachably fitted, preterably as shown, by being engaged therewith by screw threads, a nozzle, ll, the bore of which is ot' smaller diameter than the port, 4b, and the nozzle is held normally in line axially with said port by a locking arm l2, which engages a slot in the head ot` the plug, lO, and is held therein by a spring, 13. lhen the plug is in this position, air under pressure admitted to the air chamber, et, through the supply pipe, 5, is discharged in a jet through the nozzle, l1, into the sand delivery chamber, carrying with it the sand which passes into said chamber from the sand receiving' chamber, l, and discharging it upon the rail through the pipe, 8. By removing the locking arm from the plug and turning it so as to be clear of the plug, the latter may be given a half turn about its axis and will cut ott the supply ot' air to the sand delivery chamber, or the plug may be removed from its seat, for the clearing out or detachment ot the nozzle, it desired. The provision of a nozzle which is detachably secured in the plug, as above described, enables the nozzle to be replaced by a new one whenever it becomes worn to such an eX- tent as not to be properly serviceable, without involving the insertion of an entirely new plug, which latter is not subject to any appreciable wear in service, and therefore does not require renewal.
It will be obvious that the sand receiving chamber and the sand delivery chamber may be detachably connected together by any other suitable means, as for instance, by providing the parts with Hanges and clampingl tion ot' av sand receiving chamber, a remov- 50 able plug closing the bottom of said chamber, an air delivery port leading' into one side of said chamber, and a sand delivery chamber secured to the opposite side of said chamber and extending thereinto adjacent to the end of the air delivery port and having opposite lateral openings in line with the bottom plug of the sand receiving chamber.
In a track sanding device, the combination of a sand receiving chamber, a sand delivery chamber extending laterally thereinto and connected detachably thereto, said chamber having a U shaped conduit extending through its body and an opening in its top adjoining its outer end, through which access is afforded to both limbs of the U shaped conduit, a sand discharge pipe secured to the sand delivery chamberV below said open ing, and a connecting tube fitting removably in said opening and screw threaded for engagement with a sand boX.
In a track sanding device, the eombination ot a sand receiving chamber, a sand delivery chamber, a plug controlling an air admission port to said sand delivery chamber,
and the nozzle litted detachably in said plug and having a bore of smaller diameter than that of the air admission port.
