TRACK-SANDING DEVICE.

Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed July 16, 1909. Serial No. 507,989.

To all whom it may concern:

Be it known that I, JOHN GAPP, a citizen of the United States, residing at Scranton, in the county of Lackawanna a'nd State of Pennsylvania, have invented a new and useful Track-Sandin Device, of which the following is a speci cation.

This invention relates to track sanding devices of that type which utilizes fluid under pressure for the purpose of discharging the sand into the aths of car wheels.

The device 18 more particularly designed as an improvement upon the structure shown in Patent No. 695,300, granted'to me March 11, 1902.

When nozzles have been em loyed in devices of thisv character, such as eretofore devised, it has been impossible to remove and replace them without removin the sand from the sand chambers of t e devices. Moreover, nozzles have heretofore been so located as to be subjected to the constant action of the sand and have thus soon become worn out.

One of the objects of the present invention is to provide a nozzle which can be placed in or removed from position without in anywise interfering with the sand contained in the sand chamber, said nozzle being disposed at the side of the device where it can be 'conveniently reached.

Another object is to provide a means of simple construction whereby the nozzle can be securely locked after once being placed in operative position.

A further object is to provide improved means whereby any moisture or foreign particles contained in the air blast can be separated therefrom prior to the discharge of the air through the nozzle.

A further object is to provide a sand checking device of novel form designed to pre vent the sand from dischargin except when subjected to a blast of fluid un er pressure.

With these and other objects in view, the invention consists of such novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims. 1

In the accompanying drawin the preferred form of the invention has en shown.

In the drawingz-Figure 1 is a central, vertical, longitudinal Section through the device constituting the present invention. Fig. 2 is a front elevation thereof. Fig. 3 is a sectional line A-B, Fig. 1.

Referring to the figures by characters of reference, 1 designates a casting having a flange 2 extending around the upper ortlon thereof and designed to be en aged b tening means, such as indicate at 3 whereby the said casting can be securely fastened to a supporting structure. Sand chamber 4 extends into the casting from the upper end thereof the lower portion of said chamber bein slightly ofi center as indicated at 5, the ottom of said chamber bein formed of a screw plug 6, the lower end 0 which is angular so as to be readily engaged and rotated by means of an ordinary wrench; An interiorly screw-threaded outlet 7 extends from the wall of the sand chamber and is engaged by an exteriorly screw-threaded tubular member extending from a castin having an inverted substantially U-shape passage 10 therein opening into the tubular member 8 and also 0 ening into a downwardly extending disc arge pipe 11 which can be of the usual or any preferred type employed for conveyin the discharged sand to the rail. That portion of the casting between the ends of the (passage 10 isprefer ably solid, as indicate at 12, so as to constitute an eflicient partition for receiving the direct force of the sand blast and, at the same time prevent the sand from overflowing into the pipe 11 when the same is not su 'ected to the action of air or other fluid un er pressure.

I The casting 1 has a downwardly rojecting extension 13, in which is formed an air chamber 14, the bottom of which is made us of a screw plug 15 havin its projecting en angular so as to be readi y engaged and actuated by an ordina wrench. The upper or inner end of this p ug is recessed as indicated at 16 and has an outlet 17 extending therefrom and longitudinally through the plug for the escape of any liquid which may be deposited within the chamber 14. socket 18 is formed in the casting 1 at a oint above the chamber 14; and is normally c osed by a screw plug 19 constituting means for regulating or controlling the flow of air from the chamber 14 to the chamber 5. A port 20 connects the recess 18 with the air chamber 14 and a passage 21 extends from said recess to the offset portion of the sand chamber 5. The longitudinal axis of the discharge end portion of the passage 21 alines with the center of the tubular member 8, it being understood, of course, that y ins-- within said bore and bearing at its endsage 21, there being a head upon the outer projecting end of the plug and in-which a transverse groove 26 is formed. This groove is designed to receive a locking arm 27 extending from a stem 28 which isslidablyw and revolubly mounted within a bore 29 extending transversely throu h'the casting 1, adjacent to the tapered ore 22. A head 30 is screwed or otherwise secured upon one end of the stem 28 and is designed to slide within the'bore 29, there being a spring 31 upon the head 30 and one end of the bore rethrough the vent 17;

spectively, this spring thus serving to hold arm 27 normally seated within the groove 26. A fluid supply ipe 32 opens into theair chamber 14 and is designed to conductair orsteam under pressure to the chamber 14 where any condensed moisture will become separated and will be discharged The-fluid will then pass through the port 20 to the recess 18 and thence through the passage 21 to the nozzle 23. If this nozzle is disposed in active position, the fluid will be discharged under pressure through the passage 24 there in and will be projected in the form of a jet into the sand chamber 5, it obviously expelling a portion of the sand into the tubuar member 8 and against the partition 12. By adjusting the plug 19, the passage of fluids from the can be controlled.

It will be seen that, by providing a nozzle such as indicated at 23, the same is at no time subjected to the action of the sand, and, should it become warm or injured in any manner, the same can be'readily removed from the side of the casting without the necessity of disturbing any of the contents of the chamber 5. By utilizing the improved I locking means described, it becomes impossible for the nozzle to become displaced, but, by pressing on the head 30 or pulling outwardly on the arm 27 and then rotating said arm and its stem, the nozzle can be readily withdrawn from bore 22.

It is, of course, to be understood that various changes may be made. in the .construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention.
