CAR-DOOR MEcnAmsM Application filed May 14,

The principal obj ect of theinvention is to provide a hopper car door with means which,

' in addition to functioning as a door spreader and preventing distortion of the door, serves 10 to support or maintain the 'door in closed position. p a V A further object of the invention is to provide a door locking mechanism with means for forcing the door from apartially A primary feature of the invention resides in providing arailway car with a hinged door movable to open position under the influence or gravity and, in associatingtherewith,a,

latch member, slidably mounted on the door and means carried by the car body engageable with the opposite ends of said latch for maint'aimingv the door in closed position, the latch being so formed and arranged as to constitute means for preventing distortion of the door. t r

i A further feature of the invention consists in providing a hopper car doorcomposed of a pluralityof sections respectively disposed on opposite sides. of the car center sill with rigid means slidably mounted on the door sections and constituting a combined latch and doorspreader, the oppositeends thereof being engageable with hooks carried'by the car bodyfor maintaining the dooriin closed position. a j

A still further feature of the invention resides in providing the door of a railway car with 'a combined latch and doorspread'er of truss form.

As is well understood hopper cars, having 95 lading discharge openings disposed transversely of the ,car' on oppositesides of the car center sill, are provided with doors formed in a plurality of sections-and connected by a' spreader or stiifening member so as to swing together. Heretofore the door sections have 15 serving as a pivotal support for a cam 16 been connected by spreaders which are rigidly and immovably secured to each section, the opposite ends of the spreader being provided with either an immovable or movable part of the door locking mechanism to cooperate with a portion of the locking mechanism carried by the outerside sheets o'f t he hoppers. I have found, however, that the door spreader, by being suitably formed, may be arranged to function as the latchvpo'rtion of the locking mechanism without detracting from its function as a door spreader or stifi'eningelement. 7

In the drawings, 1 indicates the side sheets .of,..the hoppers and 2 the slopeor bottom sheets thereof. the outer edges of these sheets respectively defining the ladingdischarge openings which are adapted to be closed by the corresponding door sections 3' and 4. Each of the doors may be secured to thecar body by the usual hinges (not shown) so as ,toswingto open position under the influence of gravity. To reinforce the door sections their marginal edges may be flanged outwardly as at 5; Thedoor sections 3 and 4 arelconnected so as to swing together by a vmember 6 which is slidably mounted upon each of the sections by a plurality'of brackets ,l .7. This member in addition to serving as r a door spreader serves as the latch ofthe door locking mechanism. 7 In order that-the spreader may be of suflicient strength to effectively withstand the forces tending to warp and distort/the door sections it may be formed of, a plurality 'of members '8 and 9 constituting the compression and tension members respectively, of a truss.;;Adjacent vthe. points-,ofmaximum divergence of the tension and compression members 7 filler retaining them in spaced relation. So that the memberfi may be of maximum rigidity, the tension member Z9 thereof is formed-:as'a

flanged team, preferably a channel; the

flanges of which are cut away at'its opposite 1 ends where it is connected to. the compression member by rivets-11: I The ends of the com- ,bined-spreader and latchsproject outwardly v5o beyond,adjacentiportions of the hoppers to cooperate with other portions of the door locking mechanism: to tbe hereinafter de- S b d', I

The brackets [7 are respectively secured to 5 the door sections adjacent their inner and 1 outenedges and ea'elrof' the brackets consists e se ia u e i amb- 1 2 a inner, m mibl t s emm fash d-W h pp and ew zse t an lr proje ti ilo- 0r bosses l gt for: maintaining the outer member Lin spaced relation thereto, thusaffording a i ortion j forreceiving the] slidable" door a de? I ieurr t sp he ac et s 'aiit he ent -ed har swim s P r dedsw ha r c por employed for making the spreader rigid with the door sections and to thereby maintain it in locked position to prevent accidental opening movement of the door sections. Any suitable means such as rivets 17 may be used for securing the brackets to the outer faces of the door sections, the rivets preferably passing through the central portions of the upper and lower lugs 14 of the inner members 13.

JVVhile the outer. members 12 of the brackets "which are securedto the doors adjacent their inner edges. are interposed between the compres's'ion member 8 andthe tension member 9 thereof. It will thus be seen that the filler members 10 may be of any desired size, thereby permitting the divergence between the tensionandcompression members tobe varied in order to obtain a' spreader of the most effective strength. 1

Thev fillers 10, in addition to serving as spacersfor the compression and tension members of the spreader, limit longitudinal movement of the latter by cooperating with the opposite edges of the outer plates 12 of the adjacent brackets. Secured to the compres sion member8 adjacent each of the brackets Tis a wedge block or member 18 fashioned with an inclined surface 19 to cooperatively engage the correspondingly inclined surface '20 formed on the inner members 13 of the brackets. The wedge blocks 18 are'secured a depressed portion 23 to receive the inner blocks ,or' castings .1 may be employed" for :head of the rivets Suitably secured as by rivets 24: to each of the outer side sheets of thehoppers is a hook member 25'having a ledge 26, the ledges of "the hooks being respectively adapted to cooperate with the outwardly projecting opposite ends .of thedoorspreader 6. The ledge jof each of the hooks and the portions of the brackets for receiving the spreader are so arranged and proportioned that, by moving both ends of the spreader upwardly into the position illustrated in Figure 9, the door sections will be ')ermitted. to swing to open position;

When it is desired to close the door the operator may grasp any convenient portion thereof or one of the outwardly projecting ends of the movable spreader to move the inFigu're 9; 'It the doorsectiofnsare Warped" or distorted'to an extent suchthat the door may not be easil'y caused to assume fully closed position, suitable force may be applied to. the outwardly projectingends ofthe spreader by employing a removableleye'r 28 4 'adapt'edto fulcrum about the outwardly projecting lug or boss 29 of the hook.. 7 When forceisa applied to the removable lever 28 to oausethe spreader to move downwardly, the

door is forced to fully closed position due to the coaction betWe'en-tlie'inclined surface of the inner members of the respective bracketsand the inclined surface 19 of the Wedge blocksof the spreader.- vIf the door sections are being manipulated by only one operator it will, of course, be understood that ,bothof the sections cannot besimultaneousl'y locked but, as shown in" Figure 1, the door SeCtlOILt may be caused to a'ssume a fully closed position and the operator by passing around to the other side of the car may thereafter secure the door section 3 in fully closed position. Likewise, when only one operator is available to unlock the door .sections, "the opposite ends of the spreader may be caused to successively" assume a position permitting the door to swing open.

As considerable force-is required to move the spreader to unlocked positionqa mechanical advantage isp'refe rablyemployed to obtain the desired force. To accomplish this result a portion of the marginal flange 30 a o fjthe hook is cut; away as at 31 toj' provide a ledgeorshoulderforaccommodating arer a movable lever 32. Bymoving the lever in a I clockwise direction about the ledge 31 as a fulcrum, it will readily beperceived that the spreader is causedto move upwardlyg'thereby permitting the door to swing open. 7

Allipants oi the door mechanism as applied to the side dump hopper car illustratedin- Figure 10 are identical with those illustrated inthe main figures ofzthe drawings, theo11ly ditferenceibeing that the-door isfformed as a unit instead of-in sections as illustrated in Figures 1 and 2.

In. the modification illustrated Figure 11 which may beapplied either to the type of hopper illustrated in Figural or to that illustrated in -Figure' 10, the hooks are a formed with a plurality of ledges, the ledge 33 serving-to maintain the door in partially closed position While the ledge-34 functions .to sustain. the door invfu ll'y closed po'sitiom 'Insteadof providing the brackets and the spreader'b Witlrinclined, surfaces to wedge the" doonto any closed position by a down- Ward movement of the spreader, thesesurfaces in the modificationillustrated in Figure ll'are made parallel to the direction of movement of the spreadeig' the wedgingf acti'on being 'obtai-nedby conneotingthe ledgies 33 andBet of the hooks by'an inclined smface 3 5. willthus beapprecialted that when 1; In a door mechanism for railway ears,
