DOOR MECHANISM'FOR RAILWAY cA-ns.

Application filed April 1e,'1s23.- 'fseri ai No. 32,414.

My invention relates to door mechanism for railway cars of the drop'bottom or hopper type, and is particularly directed to the provision ofstrong, simple, reliable andefiicient means for maintaining the swinging doors ofthe car in'closed position.

Aprimajry' feature of the invention consists in constructing the hinged door with an outstanding marginal flange along an. edgethereof, and in securing a channel member to the under side of said door in inverted U position, a flanged member, having a dOW11-" wardly offset portion passing beneath said marginal flange and projecting beyond the yond an edge thereof, a hook or latch adapted to releasably engage said arm, and 'means f'or pivotally mounting said latch upon astation ary part of the car, the means bywhlch the latch is mounted upon the'car comprising a,

plurality of pivot brackets between which a portion of the latch extends, the inner-" most of said brackets having a plurality of inwardly projecting bosses of unequal length -the longer of which is adapted to engage a side sheetof the car and the shorter of which is adapted to engage a reinforcing member secured to the outer face of said sheet.

whereof is'pointed out in the claim s,- I Figure 1 is a view, partly in slde elevation and partly in vertical sectionQshowin'g a portion of the car equipped with devices embodying the invention.

Figure 2 is a detail sectional-view on the lineQ-EZ Fig. 1, looking in the direction of the arrows, the hinged door being in closed position and the door supporting latch r hook beinglocked against accidental release.

known type having one or more pairs of doors a The car shown in the drawings for the pur- I pose'of illustrating the invention is 'off a Well 7 1 which arehinged to the car bodyQ'by means i of suitable hinges 3. When in locked pos'ition these doors close the discharge opening of the hopper of the car, the said hopper in the form of car illustrated being constructed with hopper slope sheets 4; and side sheets 5. The doors lare preferably inclin'ed'so that they slope downwardly from their hinged edges toward the. center of the hopper discharge opening, which not onlymcreases the carry:

ing-capa'city of the car but als' o renders the door supporting mechanism more accessible and at the-same time facilitatesthe closing of the doors by avoiding the necessity of lifting them to the horizontal position. The" lower end of the sidesheet5bordering the hopper discharge opening of the car is preferably sloped or inclined to correspond to the slope of the"'c loors when in their closed positions;

and the said sheet is prefera'bly reinforcedy at sai-ddischarge opening by a bar or plate 6 riveted to the outer face of said sheet and conforming to theslopes of the bottom edge thereOfQ f Each of the' doors Ljwhichniay advantageously be formed with marginal stiffening flanges 7, is reinforced adjacent its edge ,re.'-

mote from its hinges by means of a flanged member 8 of channel cross sect1onsecurely r vetedto the under side of'the door and pref- Rigidly secured to the opposite ends of the flanged reinforcing member 8 withinthe channelthereof are door supporting arms 9 which project beyond the. correspondingly adjacent ends of said flanged member and 8X4 tend beyond the respectively"adjacent edges;

of the door'l. 7 The door supporting'ar'ms 9, which I constitute brackets for cooperating withlatchmechanism carried by a stationary part of thecar preferably are formed as flanged members of angle iron cross section,

thus enabling rolled commercialangle irons to beq .usecl for this purpose, although the erably arranged in inverted Upjosition, J'The flanged member 8 may advantageously 'eX- tendsubstantially the full'width of the door 1 members 9 may be formed as castings if desired. Each of the flanged supporting arms 9 is offset downwardly at its outer end as indicated at 10 so as to pass beneath the adja cent marginal flange 7 of the door; and the depending leg-of each door sup'p'oring arm 'may be provided with an aperture 11 for receiving a removable lever or'prying bar that ,be employed in forcing the doors to closed position. The procumbent leg 12 of the angle iron bracket 9 affords a seat adapted to be releasably engaged by a movable hook or, latch which serves to prevent the 'door from executin an oa enin movement.- It

i .{j a

V will be perceived that the elements of the dobr locking mechanism which aref'carriedby the door ''are so formed and arranged that they are con'ipaetly disposed, easily appliechsimple and strong in' construction and eiiiciently rein- TEOIfCGthG door. The means for cooperating with the respective'supporting arms 9 to sustain the doors against opening movements preferably involve a plurality of latches or hooks 13 which are; pivotally mounted upon a station ary part of the car, as for example, by. means f therespective rivets 14. "Each book 13 1S formed with a shoulder or ledge 15v adapted to "extend under andengage the adjacentflange of the supporting arm 9 carried by the door with which it is associated. The

hook may also advantageously be provided with an auxiliary or secondary ledge 16 which, as shown in Fig. 1, is alsoadapted to cooperate with the upper leg or ledge 12 of the adjacent supporting arm, means thus being provided for supporting the door in a partially closed position. It isdesirable to provide the hooks 13 with auxiliary ledges 16 because, as is well known, the swinging doors of hopper cars may very readily be raised'until they nearly assume closed position, butby reason of warping of the doors considerable force is usually requ red to bring themto fully closed position. By providing the hooks with the auxiliaryv ledges 16 the doors may conveniently. be brought'to a par tiallyclosedposition and'then may be forced toiiinal'clos'ed position bythe use of a removable lever or prying bar inserted through the aperture 11 ofthe app'ropriate'door supportingarm9. v The upper portion's'of the hooks 18 extend between bracket members 17 and 18, respectively, which are rigidly riveted to the ear.

. The lowerportion of the innermost bracketlS overlaps thebar or plate 6 reinforcing the lower edge of'the side sheet 5 at the hopper discharge openi-ng','and I'the said bracket is provided upon its inner side with a plurality of ' iiiwardlyextending bosses 19 and 20, respectively. .The upperbosses 19 are of sufficient length to extendover the reinforcing bar 6 and engagethesh'eet 5 of the car-,fwhilt: the shorter bosses QOengage the outer face sheet.

of said bar. Theseveral bosses are perforated to receive rivets by which the brackets are secured in place. The inner bracket member 18 whichserves as a filler for spacing the hooks outwardly from the reinforcing plate 6 is, as shown, preferably made of greater hei ht at its center than towards its ends, thus enabling it to function efiiciently as a beam for distributing the load from the door 7 books to thereinforoing plate and the hopper v Pivotally mounted between the brackets 17 and 18'andoperatively associated with therespeetive hooks 13 are looking cams 21 which when the hooks 13 support the door in closed position may be rotated so asjto stand behind the hooks and prevent their accidental release.

.The door supporting hooks illustrated in Figs. 5 and 6 are unprovided with auxiliary ledges. In the construction shown Fig. 5'

the hook 22 is provided below its shoulder or loeking'ledge 2'3 with a shoulder Q twhich, when the door'is in closed position,is-s"paced from the depending leg of the door supporting arm 9 a distance suiiicient'to permit intro-' duction of a b'arfso asto enable thehook to be readily released fromsupporting engage-.

ment with the said arm.

' The hook illustrated is provided with a shoulder'26 for cooperating with thedoorsupporting time to retain thedoor is closed position. In this form of hook, whose lower end 27. is curved "so that thedoor arm 9 iii'alv readily slide along it in the operation of closing the door, anout standing lug 'orsho'ulder 28 is provided to form a seat enablinga bar] to be used for releasing the hook from thedoor supporting arm.
