United States Patent O DISCHARGE OUTLET COVER PLATE Clarence J. Koranda, Western Springs, and Harry A. Withail, Chicago, 111., assignors to Enterprise Railway Equipment Company, Chicago, Ill., a corporation of ois Application February 2, 19575, Serial No. 485,789 Claims. (Cl. 10S-282) This invention relates, generally, to discharge outlets for hoppers for railway cars, trucks and the like and it has particular relation to the attachment thereto of a sanitary plate used to prevent contamination of the interior of the discharge valve housing of the hopper and the underside of the movable gate which controls the flow of lading therethrough.

Among the objects of this invention are: To provide simple, eicient and economical means for holding a removable sanitary plate in place on the underside of a discharge valve of a lading containing hopper; to hold the plate in place by wedging action; to employ a locking bar wedgingly supported at its ends for underlying the plate and holding it in closed position; to support the locking bar by a stationary keeper at one end and a pivoted keeper at the other; to provide cooperating engaging wedging surfaces on the keepers and the respective ends of the locking bar; to hold the locking bar in place by a removable locking pin; and to provide for applying 'torque to the pivoted keeper for swinging it toward the 'stationary keeper and wedging the plate into closed position.

Other objects of this invention will, in part, be obvious I and in part appear hereinafter.

This invention is disclosed in the embodiment thereof shown in the accompanying drawing and it comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims.

For a more complete understanding of the nature and scope of this invention reference can be had to the following detailed description, taken together with the 4accompanying drawing in which:

Figure 1 is horizontal sectional view taken generally along the line 1 1 of Figure 2 and showing the housing lgenerally along the line 3 3 of Figure l; and

Figure 4 is a fragmentary view in end elevation of the construction as shown in Figure 1, the view being taken from the left hand end of this gure and looking from left to right.

Referring to the drawing, it will be observed that the reference character 10 designates a rectangular steel or cast iron housing which is located around a discharge opening 11 of a discharge valve for a load containing hopper. It will be understood that the housing 10 discharges downwardly and -that the discharge of the lading from the hopper is controlled by a slidable gate (not shown) or other suitable valve means well known in the art. The present invention has to do with the protection of the underside of such a gate and the interior of 'the housing 10 from contamination. This is important when the hop- V 2,751,858 ce Patented June 26, 1956 2 per with which the housing 10 is associated is employed for transporting our, sugar or the like.

Extending outwardly from the lower edge of the housing 1G is a ange having portions 12 and 13 at the ends and 14 and 15 at the sides as shown more clearly in Figure l. Against the undersides of these flange portions there is positioned a removable sanitary plate 16. interposed between the upper surface of plate 16 and the under surfaces of the flange portions is a gasket 17. lt will be observed that the ange portions 13 and 15 are provided with inwardly opening slots 19 and 21 for receiving the corresponding edges of the sanitary plate 16 and also for receiving a detachable connection to a conveying conduit which is applied to the housing 10 in lieu of the plate 16 for unloading purposes.

The underside of the sanitary plate 16 is provided with transverse ribs 22 each having a central slot 23 for receiving a locking bar 24 that may have a square cross-section as shown more clearly in Figure 3. The upper side of the locking bar 24 bears against the underside of a longitudinally extending rib 25 that is formed integrally with the underside of the plate 16. Provision is made for wedgingly holding the plate 16 in the closed position through the agency of the locking har 24. The details of this construction will now beset forth.

In Figure 2 it will be noted that the underside 2S of the right hand end of the locking bar 24 is inclined upwardly so as to wedgingly engage an upwardly facing downwardly and inwardly inclined wall 29 of a stationary keeper 30 that is carried by the housing 10. Preferably the stationary keeper 30 is cast integrally with the housing 10, although it may be secured thereto by other means as desired.

A somewhat similar construction is provided at the left hand end of the locking bar 24. Its underside 32 is inclined upwardly in order to wedgingly engage an upwardly facing downwardly and inwardly inclined wall 33 of a pivoted keeper 34. The keeper 34 has an upwardly extending arm 3S which is positioned between spaced ears 36 that project upwardly from the ange portion 12, Figure 4. A rivet 37 extends through the ears 36 and the arm 35 for pivotally mounting the keeper 34 so that it can swing toward and away from the stationary keeper 30.

With a view to employing the wedging action that is provided through the agency of the interengaging undersides 28 and 32 of the locking bar 24 with the walls 29 and 33, a socket 38 is formed in the keeper 34 for receiving a removable bar that is indicated by conventional broken lines at 39. When the bar 39 is inserted in the socket 38 and is moved downwardly, the resultant torque applied to the keeper 34 swings it toward the stationary vkeeper 30 and moves the locking bar 24 upwardly to force the sanitary plate 16 into sealing engagement with the gasket 17.

In order to hold the locking bar 24 in operative position ears 41 are formed integrally with the keeper 34 and they extend inwardly therefrom on opposite sides of the left hand end of the locking bar 24. The ears 41 are provided with elongated apertures 42 which are arranged to register with a circular aperture 43 in the left hand end of the locking bar 24. A locking pin 44 extends transversely through the

apertures

42 and 43, as shown in Figure 4, to lock the assembly in the position shown in Figure 2. A sealing strip 45 extends through one end of the pin 44 to prevent unauthorized withdrawal. A chain 46 is secured to the other end of the locking pin 44 and to a staple 47 projecting upwardly from the ange portion 12 to prevent loss of the locking pin 44 when it is withdrawn from operative position.

In operation, when it is desired to remove the plate 16, the sealing band 45 is removed and the locking pin 44 is vvritldravv'n.V lpe'r'n'iits the pivotedkeeper 3d to swing Y The housing 116' is closed ott 4byfapplying the plate 16V after the' ladinghas been discharged; Then the bar 24 is inserted inthe f keeper 30 and thejkeeper 34 is swung to engage the other end'. The bar Q9 is inserted` in the socket 38 and the keeper 34 is movedtowardthe keeper 3 9 until the 'apertres'Z in' the `ears`41 register with the aperture $3 'in 'the left hand end 'of the bar24. The locking pin 44 then is inserted and thesealing band 451 applied.

Sincefcertain' changes can be made in the' foregoing construction and diierent embodinflents of the invention can be made withoutA departing fromjthespirit and scope thereof, it is intended that all matter shown in the 'accompanying drawing and described hereinbeforeshall be interpreted as illustrative and not in a limiting sense.
