TRACK-SANDING DEVICE.

To all whom it may concern:

Be it known that 1, JOHN GAPP, a citizen of the United States, residing at Scranton, in the county of Laokawanna and State of Pennsylvania, have invented a certain new and useful Improvement in Track-Sanding Devices, of which improvement the following is a specification.

This invention relates to track sanding devices for locomotives, and is in the nature of an improvement upon that covered in my prior Patent No. 991,145, issued May 2, 1911.

One of the objects of my present invention is to provide a combined hand operated gravity feed and fluid pressure sander which may be readily applied to existing sand boxes, and having the gravity valves located outside of the sand box whereby they are readily accessible at all times for inspection, adjustment and repairs.

Another object is to provide an improved construction having a sliding connection or joint between the receiving chamber section and the sand discharge fitting whereby the latter part may be readily removed for cleaning or renewal without taking down the other parts of the device.

Another object is to provide an improved form of air jet connection whereby moisture and foreign particles will be deposited before the air enters the jet tube, and the latter may be easily cleaned when desired; and still another object is to provide an improved gravity valve for controlling the sand discharged by hand.

These and other features of my improvement are hereinafter more fully described and set forth in the claims.

In the accompanying drawings: Figure 1 is a perspective view of the exterior of a portion of a locomotive sand box showing one form of my improvement applied thereto; Fig. 2, a view partly in elevation and partly in vertical section showing a double sanding device embodying my improvement; Fig. 3, a plan of the same, the bolts being indicated in a section taken on the line 3-3 of Fig. 2; Fig. 4, a sectional view of a portion of the device, illustrating a slight modification Fig. 5, a vertical section illustrating a single sanding device; Fig. 6, a section of the same taken on the line 6-6 of Fig. 5; Fig. 7, a sectional view illustrating a modified form of gravity valves and means for operating the same; Fig. 8, a view partly Specification of Letters Patent.

in section, and partly in side elevation, illustrating a modification adapted to be located at a distance from the sand box, and having a pipe connection thereto; Figs. 9 and 10, plans showing a modified form of gravity slide valve in the open and closed positions respectively; and Figs. 11 and 12, a plan and transverse section, on the line 00w, respectively, showing a further modification.

Many locomotives are now provided with a standard form of sand box, in which the bottom casing is downwardly inclined at the two sides and projects in the form of a fiange, 2, having a plurality of sand outlet passages, 2 and 2", and a number of bolts, 3, for securing the air sanding device and clamping the flange thereof against the sandbox, as shown particularly in Figs. 1 and 2 of the drawings. As shown in these figures, the flange, 2, of the sand box is provided with four sand outlet passages for the double sanding devices, each having an air section, 1, containing the sand receiving chamber, 1*, communicating with one of the outlets, 2 and a sand delivery section, 7, containing a gravity discharge passage, 7*, communicating with the outlet, 2*, from the sand box. The section, 1, may be formed with a flange adapted tobe fastened to the sand box flange by means of the bolts, 8. Section, 1, is also provided with an air chamber, 4, to which the compressed air supply pipe, 5, is connected. This cham her, 4, serves as a separating chamber in which moisture and other foreign particles contained in the air supply may be deposited and removed at convenient times by taking out the cleaning plug, 6, in the bottom of the chamber. The clean and dry air under pressure passes through the opening, 4, from the top of chamber, 4, into an annular space, 4*, around the nozzle, 10, which is provided with a perforation, 11, through its end and in line with the opening in the sand receiving chamber. The air nozzle, 10, is preferably made in the form of a plug or spool, with both ends threaded, as shown, and adapted to be readily inserted into its position in chamber, 4', from the exterior of the casing or section. It may then be easily removed for cleaning at any time.

The sand delivery section, 7, is connected to the section, 1, by means of a tapered nozzle, 7, having a sliding fit within the opening, 1 and containing a sand delivery passage, 7 communicating with the sand chamcharge passage, 7

and 2, or if preferred, it may be fastened directly to the flange of the sand box, as shown in Fig. 5, where only a single sanding device is employed. The sand receiving chamber, 1 may be, readily cleaned by re moving the plug, 1, at the bottom, and the sand delivery section, 7, may be readily detached for cleaning, repairs, or renewal, by simply removing the bolts and sliding the nipple, 7, out of the opening in -section,.1.

The pipe, 8, serves to conduct the sand fromthe discharge passage to the rails.

According to one of the features of my improvement, the gravity discharge passages are controlled by hand operated sliding valves, 9, which are located outside of the sand box where they are readily accessible for inspection and repairs, and they are preferably located in recesses between the flange of the sand box and the sanding device. The recess for the valves'may be formed in the face of the flange of the sanding device, as shown in Figs. 2 and 3, or in the face of the sand box flange, as indicated in Figs. 4c and 5, or they may be inserted in slots in the sanding device, as shown in Figs. 1 and 8.

As shown in Figs. 1 to 6 inclusive, the gravity valves are formed of flat L-shaped plates, and pivoted at one end on the bolts, 3, the other end being attached to the operating rod.

In Fig. 7, I have shown a straight form of gravity valve, 9, mounted on an intermediate pivot in a recess extending upon both sides of the valve whereby the same may be turned in either direction from its closed position for opening the gravity discharge passage. Any of the various forms 5 of valves may be operated directly by hand,

or a small motor may be employed for this purpose, such as a cylinder, 12, having a piston, 13, and connecting rod, 14, actuated by fluid under pressure admitted by a pipe,

0 15, as shown in Fig. 7 and controlled by any suitable form of two-way or three-way cock.

Fig. 8 illustrates a modification of my improvement in which the sanding device is 5 formed with a sand chamber, 2, adapted to be located at a distance from the sand box, as for instance, beneath the running board, and connected to the sand box by means of a pipe, 2, or it may be connected close to the sand box by a short pipe or nipple.

In Figs. 9 and 10, I have illustrated a reciprocating slide valve, 9 inserted in a V longitudinal recess in the face of the flange for a double sander, and having ports, 9, 5 for communicating with the sand chambers,

open. 7 rectly by grav ty, the valve, 9 is shifted to 1, and ports, 9, for controlling the gravity discharge openings, 7". Longitudinal slots are formed for the bolts, 3, in order to allow for the reciprocating movement ofthe valve. VV'h'en the valve is'in its normal position, the gravityports, 7 are closed, as shown in Fig. 10, while the sand receiving chambers, 1 of theair jet section are fully When it is desired to apply sand dithe position indicated in Fig. 9, in which the ports, 9, register with the gravity discharge passages, 7", allowing the sand to fall through the same, and the discharge pipes, 8, to the rails.

According to the modification shown in Figs. 11 and 12, the side valve, 9 is mounted in a recess formed in the face of an additional plate, 16, secured between the flanges of the sanding section, 1, and the sand box, 2, said valve being designed to normally close both gravity discharge passages, 7 but to be moved in one direction to open the gravity discharge of the forward sander, and in the opposite direction to openthe gravity discharge of the rear sander. Inorder that the intermediate bolt, 3, may not interfere with the slide valve, 9 it may extend only part way through the plate, 16, which may have additional bolts upon the edge thereof at this point for securing the same to the sand box, as indicated particularly in Fig. 12.

With all of the various designs shown, it will be evident that the gravity valve is located outside of the sand box, where it is readily accessible at all times for inspection and repairs; that the sand delivery section, as well as the air jet nozzle, may be easily removed for cleaning or renewals; and that the improvement may be readily applied to existing standard sand boxes of locomotives in regular service by merely adjusting the usual fastening bolts.
