This invention relates to railway cars and more particularly to an improved hopper construction and door arrangement therefor, together with improved means for holding' the doors firmly to their seats and substantially sealing them.

An important obje-st of my invention, generaliy stated, is to provide su pporting mea-ns which will serve as an emergency stop for preventing` unlatching of the doors in case they become distorted or loose, the supporting means also acting' to insure proper closing of the door against its seat.

Another object is the provision of fulcruni means whereby a pinch bar or its equivalent may be. enga-ged with the door arm and with the supporting member whereby to permit forcinpr of the door to its closed position praeti: ally regardless of the extent to which it may be distorted.

Another object is the provision of a peculia r bracket member which serves as the support for the door securing` hook and which has formed integral therewith the extension support which constitutes the emergency stop and' the fulcrnm for the. door closing pry bar, the bracket and hool structure being capable of manufacture as a unit adapted to be en- `raged upon an existing hop per f or etifectiingY securiiur of the door thereof.

The invention further contemplates` the improvement of door spreaders or stiifteners and door arms whereby their eiciency will be increased, together with minor impro veine-nts iii the general structural assembly.

To the attainment of the foregoing objects and advantages, the invention consists in the detaiis of construction and arrangement of parts to be hereinafter described and pointed out in the appended claims, although it should be understood that the present forms are merely exemplitications of preferred structure and that various changes and modifications may be made without departing from the salient features ofthe invention as pointed out in the appended claims.

In the drawings wl characters designate throughout the a portion of a hopper hopper cars,

construction illustrated ail section on the line ierein similar reference corresponding' parts several views. I have shown of the type used in twin it being unnecessary to illustrate more than this inasmuch :is the construction of cars of this type is so well known.

The hopper includes s ning' or i'ioor sheet Wlfely extendingy edge with a ple har 3 secured ther rivets 4. lio-or sheet by a door 5 which is The edges of the side 2 dene the discharge openingl for the lading and this openingisordinarily closed preferably of pitite-like construction and formed a side sheet l and the 2 equil'iped at its transstiiieiiing an- 'eto, as for instance, b v sheets 1 and with peripheral tianges 6 which operate to reinforce and stiffen the saine. it projects outwardly The door is of such size that beyond the edges of the side sheet 1 and floor sheet 2. The peripheral iiangres referred to cooperate with certain elements of the inventio scribed so as to have Doors of this type n to be hereinafter dea sealing effect.

are ordinarily hinged m0 to the car body above the hopper discharge opening with the axis of the hinge pintles extending transversely of the car. In this present instance the numeral 7 designates hinge leaves carried by the door and terminating in knuckles 8 which cooperate with and which are pivoted to the hinge pintle carried by or fastened to the car in the ordinary manner. There are usually two hopper discharge openings at an end of a car ot the type indicated and the doors tor closing the same are mounted in pairs alining with each other and connected by means ot a spreader 9 which may be secured by rivets t0 or the like. The spreader is usually tastened to `both doors so that they may be operated in unison and thereby torni in etiect a single door which may be said to consist ot spaced sections. As this construction is well known in the art it is not shown in complete detail on the drawings. The spreader is conveniently formed as a channel bar having its web lying lat against and secured to the outer side of the door by the securing elements 1t) referred to, the flanges ot the channel extending outwardly away troni the door. This type of spreader is easily manufactured and in many instances is better adapted to meet existing conditions than a spreader ot some other cross sectional configuration. Secured to the outer end ot the spreader and to the door, as by means ot rivets 11 and 12. respectively, is a door arm 13 which may be ot angle bar construction and which has one end portion offset at 1-1; t'or the accommodation ot the hinge lea T and its other endL angularly deflected or oifset to pass by the flange 6 at the end ot the door.

An important feature of my invention is the provision ot an angular strip or bar 15 located at the edge of the side sheet 1, said bar being provided with a ianged portion lo lying against and secured to the outer'side ot' the said side sheet, as tor example by rivets 16a. This bar 'further includes an outstanding portion 17 which extends outwardly iroin the hopper at the edge ot the discharge opening and which serves as an abutment for the door when the latter is closed. Vl' his portion 17 ot' the strip merges into a tlange 18 which may be substantially parallel with the door flange G and located outwardly thereof to act a seal when the door is closed. By referring to Figure 2 it will he noted that when the plane ot' the side plate 1 does not extend at right angles to the plane ot the door, the iiange 18 ot the strip or bar 15 may be inclined with respect to the side sheet 1 to correspond to the direction ot the door flange 6. At this point it should also be stated that it preferred, the door may be 'formed with corrugations or pressed out ribs l!) which lie approximately parallel with the marginal flanges and which not only serve to stitlen the door but also to co-act with the hopper at the edges ot the side sheets thereot to torni an additional seal tor the lading ot the car.

For holding` such doors closed l provide a substantially self-contained securing mechanism which includes a cast bracket 2O mounted upon the side sheet ot the hopper in such position as to overlie the angular strip or bar 15 thereon. This bracket preferably includes a main or plate portion 21 having spools or lugs thereon seating against the side sheet 1, said spools serving to space the bracket away trom the side sheet in substantially parallel relation with the flange 18 ot the strip or bar 15. A cover plate .5 is provided to overlie the pivoted end ot the securing hook 2l which is of that type having successive ledges 25 and 2G adapted to engage the door arm 1B tor holding the door in nearly or entirely closed position. have illustrated rivets 27, 28 and 29 which serve to hold this bracket and cover structure upon the hopper. The rivet 28 additionally acts the pivot tor the hook 24 and the rivet 29 serves as the pivot for a locking cam :i0 which is provided for the purpose of holding the hook 24 in engagement with the door arm 13 so that accidental displacement will not occur'.

On account ot the severity ot the service, doors ot this general character sometimes loosen and sag down away from their hinge pintles and as a consequence, the doors may become unlatched or the door arms thereof become so positioned as to prevent the doors from being properly latched. In order to prevent these defects, the bracket 2O is provided with an extension 31 preferably integral therewith, said extension projecting outwardly beyond the edge ot the hopper side sheet and beyond the plane of the closed door. This extension extends beneath the iree end ot the door arm 13 and its edge l2 is inclined so as to intersect the arc ot' swing ot the door arm thereby forming an approach plane i'or the said arm. By this construction it will be seen that when the door has sagged troni loosening or distortion ot' the parts from wear or other causes, the extension 31 constitutes an auxiliary stop for arresting movement ot the door downwardly and away from its hinge pintles. Furthermore it the door has sagged on account o the conditions mentioned, the edge ot the extension is so termed and arranged with respect to the door arm and door hook, that the door may be readily swung to a position ot preliminary closure, but upon moveing the door to a more fully closed position, the door arm will engage and move along said edge thereby forcing the door upwardly toward its hinge pintles into normal fully closed position.

It will be observed that reference has been made to preliminary closing position and 'fully closed position, depending upon whether the ledge 25 or 26 be engaged with the door arm, In explanation, it should be stated that the door may be easily swung manually into such position that the ledge 25 will engage the arm 13. For moving the door so that the arm will be engaged bythe ledge 26, with the door seating against the abutment flange 17, it sometimes becomes necessary to employ lever means such as a pinch bar, lever, long handled Wrench, or the like. To permit such action, the outer end of the door arm 13 is formed with a preferably elongated opening 33 constituting a seat through which a pinch bar, illustrated at 34, may be inserted, and the outer end of the extension 31 is provided with a socket 35 constitutingI a fuloru'm within which the lower end of the pinch bar may be seated. This socket is preferably open at the outer face of the extension and is located inwardly of the opening 33, with respect to the side of the car so that the outer or upper end of the pinch bar will extend upwardly and outwardly with respect to the car and thus be readily accessible to an operator. By applying the lever as described and as shown in 'Figure 3, the door may be forced from partly to fully closed position even though the parts may be badly distorted, loose from wear, or otherwise deranged. The wall 35, at the end of the socket, or at the end of the extension v311, is preferably thickened as it eX- tends upwardly, both the inner and outer surfaces diverging and the upper edge 37 being rounded so that the pinch bar or lever may rock upon the crown of the edge. The shape of the socket is such that the inner edge may be said to overhang the bottom of the socket to a limited extent for preventing the pinch bar from slipping out when fulcrumed in the socket during the operation of forcing the door shut. This socket is most clearly illustrated in Figure 10 which is common to both embodiments of the invention. It will of 'course be appreciated that in addition to employine the prying or fulcrum means for forcing tie door to fully closed position, it may be used to force the door open should it become stuck or frozen in closed position. To accon-iplish this result the lever is o erated in a direction opposite to that when t e door is being forced shut, its lower end cooperating with the wall of the socket Aopposite to wall 36.

In Figures 7, 8 and 9 there is illustrated a slightly modified arrangement through the general construction and most of the specific details are the same as above described. In this form, however, the angular strip or bar 15 is replaced by a stiffening bar 38 which may be riveted or otherwise secured to the side sheet 1, as indicated at 35). This stiflening` bar forms a solid base for the bracket structure 20 above described, which bracket carries the hook 24. The bar 38 is located tight joint. The other point of difference in this variation is that the spreader 4l is formed as a. Z-bar instead of the above described channel bar, one flange 42 of the Z- bar lying against and being riveted or otherwise secured to the door, as shown at 43. rl`he web of the Z-bar is outstanding with respect to the door and its other flange 44 lies parallel with and somewhat removed from the door. The door arm 45 is in this instance secured to the sheet 1, as for example by rivets 46, and may also be secured to tln` Z-bar spreader, as indicated at 47. The door arm lies above the Z-bar and its free end portion 48 offset so as to clear the flange 6 on the door. In other respects this 'form of the invention is the .same as the first desfribed form and its operation is identically the same.
