CLOSURE FOR RAIL SANDING APPARATUS Filed July 25. 1962 INVENTORS ALBERT G. DEAN HERBERT T-HERMANN A TTORNE Y United States Patent fice lb Patented Feb. 9, 1965 3,163,960 CLSURE FOR A. RAL SANDlNG APPARATUS Albert G. Dean, Narberth, and Herbert T. Hermann, Southampton, Pa., assignors to The Budd Company, Philadelphia, Pa., a corporation of Pennsylvania Filed .l'uly 25, 1962, Ser. No. 212,311 Claims. (Ci. 22h- 32) This invention relates to sanding apparatus for sanding the rail under a wheel of a railway vehicle, for the purpose of increasing the coelcient of friction between the Wheel and the rail.
In general, rail sanding apparatus comprises a sandbox which contains a supply of the sand that is to be deposited on the rail, a nozzle for directing the sand beneath the wheel, and means, such as a pneumatic air valve and control system therefor, for selectively causing sand to flow from the sandbox, through the nozzle and onto the rail beneath the wheel.
In order for the sand to fiow properly, it must be kept in a relatively dry condition. However, this is difficult to accomplish because the sandbox is normally exposed to weather elements such as rain, snow, hail and the like whereby such elements can enter the sandbox and contaminate the sand so that it is no longer readily lowable.
Heretofore, it has been customary to lill the sandbox through an opening that is covered by a screw-type cover having threads which, because of the abrasive action of the sand, are subject to galling and deterioration to the extent that weather elements can enter the sandbox even though the cover is in place.
Accordingly, one of the objects of the invention is to provide improved sanding apparatus which can be readily iilled but which prevents weather elements from entering the sandbox.
Another object is to provide an improved cover and cover actuating mechanism for a sandbox.
Still another object is to provide improved sanding apparatus wherein a cover is permanently mounted on the sandbox so that the cover cannot be lost readily.
Other objects and advantages will be apparent from the following description taken in connection with the accompanying drawing wherein:
FIG. l is a side elevational view of a portion of a railway vehicle embodying the invention;
FIG. 2 is a perspective view, of a sandbox, illustrated in FIG, 1, embodying the invention;
FIG. 3 is a vertical sectional view along lines 3-3 of FIG. 1; and
FIG. 4 is a sectional view on line 4 4 `of FIG. 3, FIGS. 2, 3 and 4 being on enlarged scales relative to that of FIG. l, for clarity of illustration.
Referring now to the drawing, there is illustrated in FIG. 1 a portion of a railway vehicle which portion comprises a car body supported by a truck 12 having a plurality of wheels 14 engaged with the upper surface 16 of a rail. The railway vehicle carries sanding apparatus for sanding one of the rails beneath and ahead of one of wheels 14, such sanding apparatus comprising a sandbox assembly 18 adapted to store a quantity of sand, a nozzle 20 for directing the sand beneath the wheel, a selectively actuatable pneumatic valve 22, and a hose 24 extending between the valve and the nozzle.
As shown in FIGS. l and 3, the sandbox assembly 18 is supported by a pair of rear angle brackets 26 and a pair of front brackets 255 beneath the bottom of the car body and inboard of the side sill 30, the front bracket being welded to a Z support 32. Brackets 26 and 28 are secured by bolt and lock nut assemblies 33 so that the sandbox assembly depends from the railway vehicle body in front of the wheel to be sanded.
Sandbox assembly18 comprises a sandbox 34, a cover 36, a cover retaining spring 38, and a throwover lever 40. Sandbox 34 includes a bottom plate 42 having an outlet 44 aligned with the inlet 46 of valve 22, there being a screen 48 extending across and above outlet 44. Sandbox 34 also includes a plurality of panels 50 arranged as shown in the drawing to provide an enclosed chamber for storing the sand that is to be deposited upon the rail. The upper front one of panels Si) is provided with a centrally located opening 52.
Sandbox 34 further includes a pair of mounting flanges 54, and an inverted, frusto-conical funnel 56 secured to panel 50 over opening 52, the axis of the funnel passing through the center of the opening. Funnel 56 is Wide at its base and narrow at its top, the top terminating in a circular, annular edge which defines or bounds a circular ll opening through which sand passes as it is being poured into the sandbox.
Cover 36 comprises a circular body SS and a pair of concentric, axially extending flanges 6i) and 62 spaced apart to define an annular groove within which is secured an annular gasket 64 of a resilient, sealing material, such as rubber. The groove formed by ilanges 60 and 62 opens towards the edge of funnel 56. When cover 36 is closed, the edge of the funnel abuts gasket 64, whereby flanges 6i) and 62 lie on either side of the edge. Flange 62, which is the outer flange, is slightly longer than flange 60 and extends downwardly over the upper edge of funnel 56?* when the cover is closed, to prevent weather elements from directly hitting the gasket and the edge. j
Cover 36 has a lug 66 at one side which supports a pivot pin 68 disposed in a pair of slots 70 of a mounting bracket 72 secured to funnel 56 adjacent the lower `portion of the upper edge thereof. Mounting bracket 72 includes a pair of flanges '74 within each of which one of slots 72 is formed, the flanges straddling lug'66. This mounting allows the cover to be `moved between an open position, indicated by the dotted lines in FIG. 3, to a closed position as shown in full lines in FIG. 3 and in FIGS. 2 and 4, wherein the cover extends across the open end of funnel 56.
Lever 4t) is pivotally mounted on the central outer portion of cover 36 by means of a pivot pin 76 supported by a pair of spaced lugs 7S integral with cover 36. Pivot pin '76 passes through one end of lever dell, the other end of lever 40 being in the form of a handle adapted to be manually actuated. Lever 40 includes a slot or notch 80 engageable with `spring 38 and a heel or stop member S2 that engages the top of cap or cover 36, when the cover is closed and locked in position.
Spring 38 is in the form of an elongated irregularly shaped resilient rod whose ends 84 are rotatably supported by a pair of spring retaining channels 36 secured to opposite sides of funnel 56 adjacent the base thereof at diametrically opposed points. Spring 38 includes a pair of arcuate sections S3 that straddle opposite sides of funnel 56, a horizontal cross bar 92 and a pair of straight portions which extend between the adjacent ends of the cross bar and the arcuate portions.
When the cover is locked in a closed position, the cross bar 92 of spring 38 engages the notch S0 of leve', 40 and biases lever 40 in a counterclockwise direction, as viewed in FIG. 3, about pivot pin 76 so that stop member 82 is biased against the outer surface of cover 36. The forces imparted to cover 36 by spring 38 acting upon the cover through both the stop member S2 and the pivot pin 76 forces gasket 64 against the edge of funnel 66 so that the gasket is distorted to completely seal the edge of the funnel. Slots 79 permit movement of the cover in a direction normal to the edge of the funnel whereby the cover is self aligning upon application thereto of the sealing force.
In order to open cover 36, spring 40 is rotated in a clockwise direction, as viewed in FIG. 3, until the spring l38 becomes unstressed so that it can be pivoted away from the notch to its inoperative position, as indicated by the dotted lines in FIG. 3, wherein the upper portion of the spring rests against the upper panel of the sandbox. The initial rotation of the lever 40 disengages stop member 82 from cover 36 and also increases the stress in spring 38 until the line of action passes over the pivot pin whereupon the spring rotates the lever until the spring reaches its unstressed position. After the spring has been disengaged from lever 40, cover 36 is pivoted away from engagement with funnel 56 to its open position, indicated by the dotted lines in FIG. 3. In such position, the cover, along with lever 40, depends downwardly and are spaced from the till opening of funnel 56 so as not to interfere with filling the sandbox with sand.
To close the cover, the cover is manually rotated from its open position to its closed position. Then, lever 4l), if it has already not been positioned, is pivoted to a position where it can receive the cross bar 92 of spring 38. Thereupon, lever 40 is pivoted in a counterclockwise direction. The initial rotation of lever 4l) stresses the spring. When the line of force acting on the lever crosses over, the spring causes the lever to snap down into engagement with the cover whereupon the spring effects the necessary seal between the gasket and funnel and locks the cover in place.
It will be thus seen that the invention is easy to operate and the parts can be readily cleaned to prevent sand from interfering with operation thereof. Moreover, the cover is permanently attached to the sandbox and cannot be accidentally removed or lost.
While only a single embodiment has been shownit will be apparent to those skilled in the art that changes can be made in the details and arrangement of parts without departing from the scope of the invention as defined in the appended claims.
