RAILWAY CAR.

Application filed March 18, 1924. Serial No. 699,986.

The invention relates to railway cars and has as its principal object to provide improvements in the door construction of the same. One of the objects is to provide an improved arrangement of door stiffener or door spreader, with door securing means carried thereby. Another object is to provide improved means for supporting the doors in partially or fully closed position. A still further object is to provide means for forcing such doors shut and for locking them in closed position. With such objects and others in view, the invention consists of the formation, combination and arrangement of parts as will be herein described and finally claimed.

In the accompanying drawings which show a preferred form of the invention, Figure 1 is a side elevational view of a portion of a railway car having a door mechanism constructed in accordance with the principles of the present invention. Figure 2 is a fragmentary end elevational view taken in the direction of arrow A, Figure 1, and showing a portion of the hopper and door, together With the door supporting mechanism. Figure 3 is a transverse vertical cross-sectional view through the door spreader or door stili'ening member, this view being taken on line 3-3 oi Figure 2. Figure 4 a transverse sectional view taken through a, portion of the car and door, this view being taken on the line 4-4 Figure 1. liigure 5 is a fragmentary side elevational view of the hopper of the car, this view being similar to Figure 1, but showing the door in partially closed position instead of in fully closed position. Figure 6 is a vertical sectional view taken through a port-ion of the locking mechanism, this view being taken on the line 66, Figure 2. Figures 7, 8 and 9 are perspective views respectively of the preliminary latching member the final latchiug member and the fixed hook or ledge car ried by the car body.

The car chosen for illustration of the invention is of the ordinary twin hopper type such as is well known in the art. The side of the car or the hopper endsheet is denoted by numeral 1. It is shown in the drawings as provided with a sealing flange 2 along the side and bottom of the discharge opening the offset 3 comprising a seat for the door l. The door is hinged at 5 to any suitable portion of the car body, the hinge pintl extending transversely of the car and the door being arranged to swing open by gravity for the discharge of the lading. Near the lower or free edge of the door there is secured to the outer face of the same a stiffening member 6 which extends transversely of the car, and in cases where individual hoppers are supplied at either side of the center sill construction of the car, this member may constitute a door spreader for uniting the two members of the door. This door stiffening member 6 is preferably formed of a channel or U- shaped section having a web portion 7 araugcd to lie in a plane parallel with the plane of the door plate. Securing rivets 8 may be passed through holes in this web and through the door plate for securing the stifiener directly against the outer face of the door. The flange or web members 9 of the channel or U-shaped section extend outwardly from opposite edges of the web portion 7 thereof, and at the outermost edges of these flange or web portions 9 there are formed in the present embodiment, return flanges 10 which stiffen the edges of the main flanges or webs 9, these return flanges 10 being arranged in a plane parallel 'ith that of the Web 7.

The door 4 is preferably formed of a steel plate with marginal flanges 11 formed around its edges in order to still'en the door plate. The end of the stiffening member 6 terminates slightly inwardly of one of the marginal flanges 11 and door supporting memhers are carried by the stiffener and comprise an extension thereof, these overlying the flange 11 so as to reach out slightly beyond the side of the car in order to coo erate with supporting means that is attachec to the side 01 the car.

The supporting means the side of the car consists, in the present embodiment, of a bracket 12 which is riveted to the hopper end sheet by means of rivets 13. This bracket is offset at 14 to pass around the shoulder 3 of the hopper end sheet and tl ,ends outwardly along the flange 2 Near its outer end this bracket is provided with a ledge 15" adapted to be engaged by pivoted

door supporting members

16 or 17 mounted upon the door. Outwardly of the ledge 15 this bracket isprovided with an approach portion 18 arranged to lift either of the

latches

16 or 17 to cause them to drop into engaging position with the ledge 15.

The latch 16 and the latch 17 are both pivoted to the door at acommon pivot center and with a common pivot pin 19. The latches that is carried by both extend withinfthe space between the flanges'or-webs 90f the doorstifl'ener 6 and swing in parallel.planes,.0ne just outside of I the other, andv both parallel-with the plane of thedoor plate. This comprises a desirable ar- .rangement of the parts as the' latch members 1 "do not occupy additional space beyond the limits of the channel and also are kept close to the door plate for greater efficiency. In order toprovide a sti'fi and substantially pivot construction, a pivot bracket is provided. This has a plate portion 21 which spans from one return or outstanding flange 1O tot-he other, the bracketas awhole beingsecurcd to the spreader by means of rivets 22 which pass thro uglr-t hese-return or'outstanding flanges.

The. bracket 20' has a portion 23 thereof ar- 7 rangefd'to extend inwardly toward the web 7 and to fit between the flanges or webs 9 of the'channel or U-shapedsection'of the door stiffening member. This portion 23 is arranged with a pierced; inner wall through which "the pivot pin 19 is inser'ted. The pivot ends of the latches ltijand 17 are inserted between the outenface ofjthe bracket'20 and one end of the pin 19 m'ay seat. As this boss isnotpi'erced' entirely through, the pin can- 'not work'out'wardly, andwhenthe bracket as a whole is'rivted to'th e" stiifening member 6 v the pin is prevented from. working inwardly by contactwith the web 7 This comprises a V neat, strongand inexpensive manner of'pi'vot- I p inghe latches to'the door stlfienmg member.

latehfl 5 is provided with an extension 25 arranged-to pass around andover-liethe side i H "Q ofthe carf This extension is provided with an aperture-.26 through which a removable door 7 1; closihg leveror pry 27 may be inserted to force 5 latch- 17 is swung downwardly into engagethe door from partiallyflclosed to fully closed position. The aperture 26'serves as a seat forth'ej lever *anathe rr-set in thebraclret V 14 'may serve as a fulcrumfor the inner end of thelever when'it is operated as afpry to force the'd'oo'r shut. .vVhen the door is-forced shut by thisor other means the ou t-er oriiinal mentf withtheiedge 15, thereby holding the door in fully closed position.

5 The latch 16 is slightly removed :from the outer,- fa'c'e-otthe door but not 'sufliciently so ..togentirely{cleartheouteriedge of the side flange, 1'1}; i-Accordingly this flange is notched at2810;;provide a way-for the swinging ,of 'this latch 16. The upper edge of the 'latchlddiis" also depressed slightly at. 29

to'provide necessary clearance between the latch and the upper flange or web 9 of the channel 6 when the latch is lifted upwardly to release the door. The outer latch is similarly depressed at 34. It is preferable that the closed door he supported near or upon the side flange 11 and to this end the outer latch 17 is provided with an extension 30 along its lower edge which extension is ada )ted when the door is closed, to'seat direct y against the flange 11 at 31 which is immediately below the cut-out portion 28 thereof. This construction also prevents the latch from dropping below the approach or run 18.

In order to lock the latch 17 in engaged position an eccentric cam 32 is pivoted to the bracket 12 immediately above the latch. When thisfis driven against the portion 25 of the latch 17 an effective lock is thereby provided to prevent disengagement of the latch 17 from the latch 15. The latch 17 in turn locks the latch 16 by means of the extension or lip 33 formed along the top edge of the latch 17 This lip is adapted to overlie the top of the latch 16, thereby interlocking the two latches in such manner that the preliminary latch cannot bewithdrawn until the outer latch 17 has first been withdrawn, so that in this way the eccentric cam 32 will serve to lock-both latches. 7

As trouble has been experienced by workmen locking the door when supported in only a preliminary or partial position of closure,

the arrangement and dimensions of the arm 25 and the eccentric locking cam or keeper 32 are such that, when the door is supported in partially closed position by the pivoted latch 16, the cam or keeper 32 cannot be rotated into holding engagement with the arm 25 of the latch 17. Upon the door being moved to fully closed position, the latch 17 will drop behind the ledge 15 of the bracket or hook 12. With the latch in this position the cam 32 may be readily rotated into locking engagement with the arm 25, as clearly shown in Figure 1 of the drawings. I
