RAILWAY CAR Filed March 19, 1924 wi tneoo Patented Jan. 14, 1930 ATET OFFICE BYERS W. KADEL, F BALTIMORE, MARYLAND RAILWAY CAR Application filed March 19, 1924. Serial No. 700,242.

This invention relates to railway cars, and has as its principal object to provide an improved form of door supporting mechanism. Another object is to provide an improved arrangement of door stiffening member and cooperating door supporting mechanism. Another object is to provide means for supporting the door in a plurality of positions of closure and also to provide means for receiving a removable door-closing bar or lever by which the door may be forced shut. With such objects in view the invention consists of the formation. combination and arrangement of parts as will be herein described and finaliv claimed.

In the accompanying drawings which show a preferred form of the invention, Figure 1 is a fragmentary side elevational view of a 0 portion of a hopper of a railway car of the well known twin hopper type, showing one of the usual doors employed with this type of car and showing also a door supporting mechanism constructed in accordance with M theprinciplesofthepresentinvention. Figure 2isafragmentary outer face View of the door, showing also portions of the hopper and the door supporting mechanism, this view being taken in the direction of arrow A of Figure 1. Figure 3 is a transverse vertical sectional view taken through the door spreader or stiffener. on the the line 33 of Figure 2. Figure 4 is a transverse sectional view taken through a portion of the hopper and the door, on the line 44 of Figure 2. Figure 5 is a side elevational view of the latching member used for supporting the door. Figures 6 and 7 are respectively an end elevational view and a plan view of the same member. Figure 8 is a detailed View, partly in elevation and partly in section, showing the latching member in preliminary engagement with the fixed hook or ledge member. Figure 9 is a view similar to Figure 8 but showing the latch member in final engagement with the fixed hook.

Referring to these drawings. the side of the car, or in the present embodiment the side sheet of the hopper, is denoted by the numeral 1. The hopper is shown as furnished around its discharge opening with a stiffening'bar 2 which is secured to the side and slopesheets by means of rivets 3. For closing the hopper opening a door 4 is provided, this bein preferably a steel plate with outstanding Flanges 5 formed around the margins thereof. The door has the customary hinges such as shown at 6 for pivotally connecting it to any convenlent part of the car body so as to swing to open position under the influence of gravity. In twin hopper car construction the door extends transversely of the car and the hinge pintles are arranged with their axes transversely of the car. It has been found entirely practical to close such doors to at least a preliminary position by hand or by swinging them with the foot.

It is the practice in twin hopper car construction to separate the hopper on one side of the car center sill from the hopper on the other side thereof and when this is done the door is usually made in two sections, one for each hopper, as illustrated for example in the patent to W. E. Wine, #1,491,57 6, April 22, 1924. 'As is well known a member is commonly employed for connecting these door sections to cause them to swing as one and this member, in addition to functioning as a spreader, serves to rigidify and stiffen the door plates against forces tending to warp and distort them. While only a portion of one of the hoppers and its co-acting door is 30 disclosed in the drawings it is to be understood that the construction is duplicated on the opposite side of the car.

In the present embodiment of the invention the spreader or stiffener is preferably rolled or pressed and is generally of channel or U-shape in cross section, being formed with a web portion 9 arranged to lie in a plane spaced outwardly from and parallel with the door. From opposite edges of this portion 9 webs or main flanges 10 extend back toward the door in a direction substantially at right angles to the plane of the web. These webs or main flanges 10 are provided with small return or outstanding flanges 11 which are bent in such direction as to lie fiat against the outer face of the door, and rivets 8 pass through these return flanges and through the door plate for securing the member 7 to the latter. The stiffening member 7 terminates near or preferablyjust inside of the side flange 5 of the door and whensecured to the door as above described the open end of the member 7 pro- Vides a socket into which one end of a removable bar 12 may be inserted. This bar may bear against the outer edge of the flange 5 so that it is confined between a portion. of the member 7 and a portion of the door and may accordingly be employed as an extension from the door or from the stiffener 7 to assist in forcing the door shut. When not in use this bar will be removed as otherwise it may extend out beyond the car clearance limits.

The present im'ention provides also improved means forsupporting such doors in closed position, said means including means associated with a door stiffener of this or any other suitable character for co-operation with means carried on the car body. In the present embodiment there is affixed to the car body by means of rivet-s 13 a fiited hook member 14 having a ledge 15. This ledge is arranged slightly outwardly of the door plate when the door is in closed position. The hook or ledge member 14 is also suitably cut away to provide clearance for the operation of the bar or lever 12. For co-operation with the ledge 15 a latch member 16 is pivoted upon the stiffening member 7, the latch being preferably integrally formed with pivot trunnions 17 extending out from each side of the latch. One of these trunnions is adapted to bear within a suitable aperture formed in the web portion 9 of the stiffening member .7, the aperture being removed slightly from the outermost end of the latter. The opposite trunnion 17 is adapted to fit within a similar aperture in a pivot bracket 18 which surrounds the pivot end of the latch and is'secured to the main flanges or webs 10 of the stiffening member 7 by means of rivets 19. It will thus be seen that when the latch is assembled with the bracket 18 against the outermost face of the web of the stiffener 7 and the rivets 19 are driven, the latch is thereby firmly affixed to the stiffener 7 in such a manner that it forms in effect an extension thereof. The outer end of the latch 16 beyond the limits of the stiffener 7 is arranged to engage back of the ledge 15 to support the door. It will be noted that when pressure from the lading comes against the-interior face of the door the outermost end of the stiffening member 7 will bear against the latch 16 at 20 so that there will be but a small distance to be spanned by the latch between the end of the member 7 and the fixed hook 14 thereby minimizing bending moments in the latch.

The ledge-engaging portion of the latch 16 is formed with a plurality of ledge engaging faces 21 and 22. respectively. The first or lowermost of these is denoted. at 21 and it will be seen in Figure 8 how this ledge cooperates With the shouldered hook 14 when holding the door in full in closed position.

it is desired to hold the door in a partly closed position. The door may usually be pushed to this position by the foot. The bar 12 or other means may then be employed to force the door to a fully closed position, and the final ledge-engaging face 22 may then be. caused to engage behind the ledge 15, thereby closed position. The outer face 22 is beveledand the ledge 15 is correspondingly undercut so as to prevent the latch from accidentally working upward to unlocked position when the car is loaded. Sufficient clearance is provided between the inner face of the door and the outer end of the hopper to permit the slight inward movement necessary to allow the beveled face 22 of the latch to be released from looking engagement with the undercut face 15 of the hook member 14. This construction of.the

latch eliminates the'necessity for a separate locking cam. The outermost end of the latch 16 is also provided with a locking gib 23 that engages the side of the hook 14 to prevent relative transverse movement of the latch and hook. v

It will be noted that, due to the relative disposition of the pivot point of the latch, the end of the stiffener and fixed hook, the force reaction between the outer end of the latch and the stiffener constitutes a major part of the entire force required to support the door By mounting the latch so that it overlappingly engages an outer face of the door stifiener the latter afi'ords an abutment for the latch whereby the force reaction between the door and theouter end of the latch is distributed throughout the entire door plate and is not concentrated in localized portions thereof as would occur should the stiffener not be interposed between the latch and door. Substantially even distribution of the major portion of the force reaction in: cident to supporting the door in closed position prolongs the life of the door plate as forces tending to warp and distort it are practically eliminated. It will be appreciated also that by pivotally connecting the latch to the stiffener independently of the door plate, not only will the forces to which the outer end of the latch is subjected, be evenly distributed throughout the door plate but the forces to which the inner or pivot end of the latch is subjected will likewise be so distributed.

Mounting the latches on the stiffener independently of the door plates also enables the latches to be applied to the stiffener before the latter is secured to the door plates and permits renewal or replacement of the door plates. without the necessity of refitting or realining the door-supporting mechanism. Furthermore, as the door-supporting loads are restricted to the beam and latches, itwill be appreciated that the strength of the door plates does not enter into the strength of the door-supporting mechanism.
