This invention relates to railway carsand has among its objects to provide improve ments in door securing and supporting mechanisms. Another object is to provide a door securing mechanism which may be appliedlto a relatively small hopper sheet. A still further object is to provide a counter-weighted door-supporting member arranged to engage the door upon upward movement of the With such general and other more specific objects in view the invention consists of the formation, combination and arrangement of parts as will be herein described and claimed.

supporting mechanism constructed in accordance with the principles of the present invention. Figure 2 is a fragmentaryiend elevational view of the hopper of the car showing the door mechanism attached thereto, this figure being seen in the directionof arrow 2 in Figure 1; C Y

The car shown in the drawings is of'the general type shown in Pilcher 1 Patent 1,437,441, and embodies a side 1 and an inclined floorsheet 2 extending upwardlyflto near the end of the car. Near the foot of the inclined floor sheet is an end hopper sheet 8 secured to the floor sheet 2 by means of Y rivets 4. Extending transverselyo-f the car is a chute plate 5 which is attached to the end hopper sheet 3 by means of rivets 6. The

outer edge of the sheet 5 and the outer ed e of the sheet 3 formftogether with suitab e edges of plate 1, a hopper discharge opening.

' the outwardly swinging door 7. .This door may be hinged to the car body in any cone 'venient manner; and as the construction 18 well known in the art, the hinges are not indicated in the resent drawings. The door may be provi ed with a z-bar stiifening member 8 secured in place by meansof rivets such as 9, said stifieningmember being located near the footof the sheet 2. This stiffening member is shown in the drawings as extendingonly to the end of the door and there is secu'redtoit-by means ofrivets 11 hopper sheet 3 to form means for coopera-- tion with a door's'upporting hook 12; The

outwardly at 13to formkan end angle 10. t y

The door-supporting hook12 lies substantially horizontal when in engagementiwith the door and is 'pivotally attached to the endhopper sheet at the pivot pointl. For

preventingthe hook from creeping 0a the this purpose abracket 15 isfsecuredto the end hopper sheet This bracketlies against 1 the outerface ofthehopper sheet 3 and may have a'suitable trunnion formed upon it to comprise a pivot for thehook 12. A BCODd trunnion maybe carried bythebracket '15,

I upon whichjmay be pivotally arrangedthe Intheaccompanying drawings Figure 1" is a fragmentary side elevational viewof aportion of a car and its door, with a doorcam, 'andjsecuring rivets 17 and 18 may pass through this plate and through thehook and cam trunnions respectively, and also through the end hopper sheet 3 to secure'these parts I "together. I

An additional securing rivet 20 may pass directly through an offset portion of the p1ate"19 and the bracket 15 as vvell1 15;

through end hopper sheet 3. I a a It frequently happens that hopper sheets such as 3 are of limited extent soth'at it is with difiicultyth'at suitable door+supporting mechanisms can be applied thereto. 1 In thepresent invention the J ledge portion of the hook is arranged toswing upwardlycinto engagement with the angle iron 10. This form andarrangement-of hook can be "applied to cars where the sheet 3 is of'limited extent. r

It is the practice in such cars to swin' the "doorsshut byhand and accordingly 1t;is

desirable that the supporting hook may at all timesibe ready for engagement with p the door To this end 'thehook 12 is extended beyond the pivot point 14 thereof soas .to form an extension 21 constituting a counterner' end of the hook 12 lies beneath the plate 2 and the outer end is provided with the customary main supporting ledge 22 andmay 23, which ledges may engage the downstan ing leg of the angle 10 to hold the door in completelylclosei or partially closed position. The outer end of the hookis provided ;'with an approach portion 24whichwill coact outer end of one leg of the angle 10 is bent with the angle iron 10 w the hack to v weight 'whiohwillat all times tend to swing the outer end of the hook upwardly. The in;

also have'the preliminary supportingled e r swing downwardly as the door is closed. The hook will then swing upwardly by gravity into engagement with the angle. The

counter-weight portion 21 of the hook is cut.

away at 25 toprovide clearance for the swinging of the hook at the hub of-the cam 16. The cam 16 co-operates with the counterweight portion of the hook, so that it also is located beneath the sheet 2. I have thus described an embodiment of my invention. Other embodiments are contemplated, within the scope of the appended claims, without departing from the spirit thereof.
