RAILWAY HOPPER CAR OUTLET Filed Dec. 8, 1938 3 Sheets-Sheet 3 iii 'HIIL $44 18' INVENTOR 44 John J. "Bride mild/{2A ATTORNEY Patented July 29, 1941 RAILWAY HOPPER CAR OUTLET John J. McBride, Bayonne, N. J., assignor to American Car and Foundry Company, New York, N. Y., a corporation of New Jersey Application December 8, 1938, Serial No. 244,659 13 Claims. (pi.105 2s0) This invention relates in general to railway hopper cars and in particular to such cars intended for transportation of cement or other fine, granular materials and has particular reference to means for closing thehopper outlet against discharge of lading or ingress of moisture.

Hopper cars intended for transportation of cement, carbon black; sugar or other fine, granular materials must be protected against the elements and accordingly ears of this type are covered and sealed to prevent loss of lading or entrance of moisture. It is comparatively easy to seal the roof, side walls and hopper sheets, but considerable trouble has been occasioned by the hopper outlet. This outlet must be closed by some means which will prevent loss of lading or entrance of moisture to the car and alsomust be of such form as to permit attachment of a discharge boot or similar means preventing loss of discharging lading or contamination'thereof by moisture or foreign matter. The most satisfactory hopper closure so far has been a sliding gate which may be readily operated after attachment of the discharge boot, but this outlet has caused trouble on several instances due to the packing'of material in the slide grooves and has also caused trouble due to the displacement of the packing gasket by the sliding gate. 'It is an object, therefore, of the present invention to provide a hopper outlet gate in which the resilient sealing gasket can not be displaced by the gate.

A further object of the invention is the provision of a hopper outlet gate pivoted to the hopper outlet to swing downwardly but with its pivot so arranged that the gate may be bodily lifted toward the hopper.

A still further object of the invention is the provision of a swinging and vertically shiftable gate which may be operated after attachment of the discharge boot. 7

.Yet another object of the invention is the provision of a swinging and vertically shiftable gate which may be operated after attachment of the discharge boot and with the frame for the gate so..arranged as to prevent any entrance of moisture or foreign material at any time.

These and other objects of the invention will be apparent to-persons skilled in'the art from a study of the following description and accompanying drawings, in which Figure 1 is in part an end elevational and in parta sectional view showing the hopper arrangement with parts broken away to more clearly disclose the construction;

2 is an enlarged elevational view of t hopper outlet;

Fig. 3'is an enlarged sectional view taken substantially on line 3-3 of Figure-1;

Fig. 4 is a sectional view taken substantially on line -44 of Fig. 3; Fig. 5 is a sectional-view similar to Fig. 4 but 1 showing the gate in open position; r

Fig. -6 is a sectional view similar to Fig. 4 but showing the gate in parallel openposition, and Fig, 7 is a partial elevational view showing" the attachment of the operating chain to the car structure.

Referring now to the drawings in detail, it willbe seen that the hopper out-let has been applied to a car -of more'or lessconventional type with side stakes 2, roof- 4 having covered entrance hatches 6 held in place by locks 8. Y The oustomary running board II! is provided as is also i hand-holds l2, permitting entrance and exit to and from the hoppers. The car is provided with bolsters l4, center bearings l5, side bearings l8 and side Walls 20; all of more or less conventional type. The hopper outlet opening is formed between side slope-sheets 22, and slope sheets 24 and centrally positioned sheet 26, which may be integral with the center sill housing. The

lower edge ofthese sheets forming the hopper openingare secured in any suitable manner, such as'welding, at W to the metal frame B forming the outlet proper.

The outlet frame is preferably cast in one piece with the sides preferably of 2 cross section, with the lower flange 28 directed outwardlyjfrom the lower edge of web 30, while' the upper flange 32 extends inwardly from the upper .edgejof the web and terminates in an inclined reflanged portion 34 conforming to the contour of the hopper forming sheets.

the edge of the flange with a groove 36 adapted to receive -a rubber or other resilient gasket 38. Thus it will be seen that anoutlet frame is proline as is clearly shown and the end portions have holes drilled in the web thereof to'receive a pivot rod 40 secured to the frame by any suitable means, such as welding; The flange 32 "isprovided with holes through which securing bolts 42 may extend and'which "boltstogether NT OFFICE? The lowersurface of the inwardly directed flange 32 is provided adjacent with the nuts and Washers effectively close the bolt holes at all times. These bolts are L-shaped and of such a length that theL head 44 may contact with lugs 46 cast or otherwise secured to the lower portion of the frame web and which lugs will serve to prevent rotation of the L headed bolt in a clockwise direction as viewed from the threaded end thereof. These L bolts may be raised or lowered relative to the frame byof which is enlarged and cored to provide an elongated opening 56 adapted to receive the hinge rod 40 previously referred to and to permit translatory movement between the door and hinge rod. At least two of the marginal edges of the door are provided With lugs 58 formed thereon in such a position as to permitcontact with the upper surface of the heads of the L bolts. The edge of the door or gate opposite the hinge rod opening is also provided with a pair of outstanding lugs 60 adapted to receive pin 62 upon which is pivotally mounted between the lugs a latch member 64. This latch member is provided with a latching shoulder 68 adapted to engage with a surface 68 formed by a part of the flange 32 previously referred to. latch member is connected to one end of a chain 10, the upper end of which is connected to a ring 12 by means of which a chain may be more,

readily grasped and also held in position upon a hook 14 carried by the car structure. In the instance shown the uppermost link of the chain is provided with an elastic or other suitable plug 76 adapted to seal the opening 18 in the flange 32 through which the chain must pass as thedoor moves to open position. This plug will effectively seal the opening and prevent the chain from being pulled through the frame and into the discharge boot.

The operation of the improved hopper outlet is as follows assuming the parts to be in the The upper end of the position clearly shown in Figs. 4 and 7: After attachment of the discharge boot the ring 12 will be disengaged from hook [4 allowing the chain to drop freely over the side of the outlet casting. Rotation of nuts 48 in a counter-clockwise direction will permit the L headed bolts to lower, thus lowering the gate until such time as the free play in elongated pivot opening 56 is taken up and the shoulder 66 of the latch engages surface 68 of the frame. As soon as the door is supported by the hinge rod and latch, the L headed bolts will turn to such a position as to clear the lugs 58 and place the L heads 44 substantially parallel to the outlet casting webs 30 but still effectively sealing the bolt holes against free entrance of moisture due to the presence of the bolt shank in, the hole and due to the capping effect of the washers and nuts. The door or gate will now be in the position as shown in Fig. 6 with the door entirely free of the resilient gasket and the L headed bolts turned with the L head parallel to the web of the frame. The latch 64 may now be knocked out of engagement with the surface 68 of the frame, permitting the freededge of the gate or door to drop, pulling the chain 10 through the opening 18 until such time as the gate is fully op ed and the plug has closed and sealed the opening (Fig. 5). In this manner all openings into the frame are closed against entrance of moisture or other matter by the bolts, nuts and washers and plug 16 as well as by the welded hinge rod. After discharge of the lading the operator may grasp ring 12, pulling the door up to such a position as will permit the latch 64 to engage the frame, holding the door in the position shown in Fig. 6. The L headed bolts are now rotated until the heads engage under the lugs 58 on the door as is indicated by the beveled upper end on the bolt, after which the nuts are tightened to raise the door into sealed position as shown in Fig. 4. The upward motion of the door to final sealed position is, of course, permitted by the elongated hinge opening and by the latch which has a plain shank below the shouldered portion 66.

It will be seen from the preceding description that an extremely simple outlet casting has been provided in which a door may be mounted for vertical shifting and rotation. Due to the lowering and rotation of the door in the opening, the gaskets are never subjected to any force other than purely compressing and can not be torn from position or injured by discharging material. Likewise, the gate will be easy to operate since it moves in the direction of lading discharge at all times during opening.

While the invention has been described more or less in detail, it is obvious that various modifications and rearrangements of parts may be made'and all such modifications and rearrangements of parts are contemplated which will fall within the scope of the following claims.
