6 Claims. (Cl. 105-308) My invention relates to railway car door construction and the like, and more particularly to the door construction and related discharge door framing identified therewith.

One of the objects of the invention is to provide a discharge door having a rigidifying embossment adapted to reinforce the door in various directions and of such a formation as to permit the placement of door latching means within the said embossment.

Another object of the invention is to provide an improved discharge door suitably constructed to cooperate with door latching means in such a manner as to form a door with a rigidifying embossment acting to strengthen the door in various directions and at the same time accommodate door latching means.

Still another object of my invention is to provide an improved door which will cooperate with a door framing structure in such a manner as to enable the combining of the entire parts entering into the door supporting means and latching means in an assembled unit which may be applied to the car structure as a self contained unit.

A still further object of the invention is to provide a door having pivoted latching means and to so offset the body of the door in different planes that the latch will lie between the said respective planes.

My invention further resides in certain other details of construction as hereinafter will be apparent from the following description in conjunction with the accompanying drawings which illustrate embodiments of my invention.

Referring to these drawings,

Fig. 9 is a front elevational view of the door assembly as shown detached from the car structure; and

Fig. 10 is a horizontal sectional view taken on a line Ill-ill of Fig. 7. w

My invention is illustrated as being embodie in a hopper car of the W-type in which the hoppers extend below the centersills and are arranged with the hoppers on each side of the centersill in transversely aligned pairs and each hopper is provided with a discharge opening and individual doors for said respective openings. The doors of each pair are transversely aligned and in the present embodiment of my invention are operated independently of each other.

Since the hopper structures on both sides of the centersill are of similar construction, the drawings illustrate the details of the structure on one side of the centersills, and only suflicient of the car structure is shown to illustrate the relation of the parts. Referring first to the construction illustrated in Figs. 1 to 5 inclusive, the centersill structure is illustrated by one of the beam members ll! of the centersills and is of the type having a vertical web section I l and lower outstanding marginal flange sections it and 13. The upper portion of each member includes an intumed flange l3, the beam members on the opposite side of the centersills being united by a main cover plate It.

The hopper on each side of the centersills is defined by upper and lower longitudinal sloping walls l5 and I6 respectively, and by inner and outer side walls Ill and I8 respectively. The side walls are spaced transversely of the car from each other and united with the upper and lower sloping walls l5 and I6, all of which are arranged to provide a discharge opening disposed in a plane at an approximate right angle to the sloping floor sheet I6. The side wall of the car includes a vertical sheet I 9 and the lower marginal reinforcing member 26. The outer hopper wall l8 has a flanged portion 2| riveted to the side wall of the car and is further formed with a flange portion 22 extending inwardly towards the centersill of the car to form a support for the upper sloping floor sheet IS. The wall I8 is further provided with an inwardly directed flange 23 extending beneath the lower sloping sheet IS.

The inner hopper sheet I! at its upper edge is provided with a flange portion 24 which is vertically disposed in a plane parallel to the centersill web II and riveted thereto. The main body portion of the hopper sheet I1 is deflected downwardly at an angle as indicated at where it crosses the outwardly extended flange of the centersill and thence continues vertically downwardly, thereby presenting the main body portion of the hopper plate as indicated at 25, and joins with the sloping bottom sheet II by being flanged under the same as indicated at 21. Said downwardly extended wall 25 of the hopper wall portion l1, adjacent the hopper opening, is spaced from the lower marginal flange II of the centersill a sufficient distance to accommodate a hopper frame structure hereinafter more fully described.

The outer hopper sheet ll extends downwardly and inwardly towards the centersill thereby cooperating to form a trapezoidal shaped opening providing for a discharge opening of greater length adjacent the upper portion of the door as compared with the lower portion of the door opening;

The hopper discharge opening is defined by the marginal edges of the hopper plates [5, II, II, and IO and is adapted to be closed by the door and frame assembly constituting the main feature of my invention.

The assembly of door and frame, as shown in Figs. 1 to 5 inclusive, is preferably formed of cast steel parts and consists of a door frame A, which extends completely around the door opening, and a discharge door B pivotally mounted on the door frame by hinge pins C. The frame A, adjacent the lower portion and centrally thereof, is formed with an integral keeper D adapted to'cooperate with a latch bar E, the latter being -pivotally mounted on the door by means of a pivot F. Adjacent its swinging end the bar is extended upwardly, and a pivoted locking dog G cooperates with said extension to lock the bar in place, said dog being mounted on the door structure at H. overlying the latch bar E and the locking dog G is a guiding wall element J.

The reinforcing frame A includes an upper beam portion 2| which underlies the upper sloping. wall II and a lower portion of stirrup-like formation extending around the sides and bottom of the hopper. The stirrup portion includes verticalleg members 25 and II and a lower horiaontflly disposed portion II. The elements 29, 5. and II are preferably of T-shaped section, and the upper portion 20 is preferably of angle section and is formed with a pair of integral depending hinge lugs 32-42 for the purpose of accommodating the door pivotal mountings C.

The integral keeper D is formed with a hook shaped portion 33 which projects through an opening 34. (Fig. 4) in the door B and engages with the bar E for locking the door in closed position. The underlying portion of the lower beam II of the frame A adjacent the said keeper is enlarged as indicated at 35, and upstanding from said enlargement the keeper is formed with an integrally formed'triangular shaped bracket portion 55 which is arranged to abut the door and rearwardly of its abutting face is formed to shed ladlng, from the hopper and prevent material from pocketing around said keeper.

The door B, which may be formed of cast metal, is preferably of trapezoidal form to correspond to the shape of the discharge opening and is pan-shaped to enclose one edge of the frame A. The door comprises a body portion 51 presenting a substantially flat single surface adapted to contact with the four edges of the door frame. Extending upwardly from said body portion 31 the door is provided with the integral flange 38 which gives the door its pan shape. The flange is continuous around the edges of the door and is reinforced adjacent its upper edge with an integral beading 39. Formed integrally with the body portion 31 and the upper adjacent flange 38 of the door are hinges 40 adapted to cooperate with the hingebutt portion 32 of the frame A. Each hinge 40 is reinforced by means of a rib 4|.

The body portion 51 of the door, commencing at a short distance beyond the swinging edge thereof, is formed with ah upwardly extending box-like portion which constitutes an offset or embossment 42 raised above the main plane of the door 31. and lying in the plane of the frame.

' The embossment includes a raised panel suri'ace 43 united with the remaining portions of the door by means of connecting

walls

44, 45, 45, and 41, which are preferably formed on a slope to prevent lodging of material. The depth of the oil'set 42 is preferably made to correspond with the depth of the pan-shaped door, said depth being of suillcient extent to accommodate therein, between the plane of the respective walls representing the main body of the door 31 and the panel 43, the body portion of the latching bar E, also the body portion of the dog G.

The latch bar E adjacent its pivotal mounting is retained in position by means of an overlying wall 48 which is integrally united with the door body adjacent the lower horizontal oil'set wall 44 and the inner vertical oil'set wall 45. This wall 4| in combination with the panel wall 43 and the said offset

walls

44 and 45, define a pocket, within which the pivotal end of the latch bar is received and guided. The overlying wall 48 is preferably disposed in substantially the same plane as the main body portion 31. The wall 48 in combina-' tion with the wall 43, forms carrying means for the pivotal mounting F oi'the latch bar.

Adjacent the swinging edge of the latch bar E there is provided laterally projecting portions and II, respectively disposed on the latch E and the dog G; said lateral projections extend outwardly beyond the indented portion of the door, thereby forming convenient means for operation of said latch members. The guide member J which overlies the latch and dog, is provided with a plate portion 5| which lies against the main body of the door and is riveted thereto adjacent the lower margin of the door by means of rivets. The member J is also secured to the door by means of the rivet of the pivot H. The inner surface of said member J constitutes guiding means for the latch bar'and the latch dog. On one side of said member there is provided a lug adapted to engage with a corresponding lug lid on the dog G for the purpose of limiting the swing of the latterin an unlocking direction. On the outer side of the member J there are provided

lateral projections

54 and 55, the former constituting a ledge on which a removable bar, indicated in conventional dotted lines at 58, is adapted to bear for cooperation with the lateral lug 49 of the latch bar. The projecting ledge 55, which is preferably disposed adjacent the lower margin of the door, is provided with an opening 51 whereby a pinch bar or other suitable tool, indicated in conventional dotted lines 58 (Fig. 2), may be inserted therein. By bearing down on the outer end of the bar, the operator may conveniently close the door. The ledge 55 is braced relatively to the adjacent door portions by a pair of braces 55.

The embossment 42 is of such a shape as to accommodate the latch E and dog G in any of their-positions of swing, and for this purpose said embossment, adjacent the swinging end of the latch, is formed of an arcuate portion 60 and is of greater width than the opposite end where the embossment is formed of only suflicient width to accommodate the latch bar E, it being noted that the width of the embossment is approximately twice that of the bar, thus permitting of the easy removal or insertion of said latch member in the pocket provided in the corner of the offset by wall 48.

In a door arrangement of the type illustrated in the embodiment shown herein, the lower connecting wall 44 extends contiguously with the swinging edge of the door, and the walls 45.and 41 extend in a, direction substantially at right angles to the swinging edge of the door and merge into the upper wall 46, the latter being united to wall 41 by the arcuate portion 60 and converging downwardly from said arcuate portion towards the pivoted end of the latch. The wall 46 extends diagonally across the trapezoidal shaped door between the corners of the door having the greatest span therebetween. The connecting

walls

44 and 46 are inclined in the direction of flow of the load and are preferably disposed at a greater inclination to the main body of the door than the

side connecting walls

45 and 41, and thus the tendency for the pocketing of material is minimized. It will be noted that the walls 44 and 4B of the embossment provide reinforcement between the side edges of the door.

Continuity of reinforcement of the wall 44 is interrupted adjacent the free edge of the door by the opening 34, and in order to compensate for such break in continuity there is provided on the outer side of the door an outstanding flange 6| which extends for an appreciable distance on each side of the opening and is of such shape as to extend beneath the hook as indicated at 62 and upwardly at each side thereof as indicated at 63-63 and thereafter contiguously to the swingingedge of the door by portions 64 lying substantially in the plane of the portion 44 of the embossment. Around the upper portion of the opening 34 there is provided a heading 65 which forms a runway or guide for the latch bar during its movement, said beading merging into an integral rib 66 at the center portion of the door.

At each of the pivots F and H there are provided depressed portions in the raised panel plate of the embossment, as indicated at 61 and 68 respectively, for the accommodation of rivet heads within the plane of the raised panel plate portion 43. The bearing surface of depressed portion 68 merges in a rib 68a which constitutes a runway on which the latch bar E is adapted to bear throughout its entire range of movement.

The keeper D is provided with a bearing face adapted to conform to the shape of the door, said bearing face including surfaces 60 and 10 adapted to respectively contact with faces 43 and 31 of the door, and said respective faces 69 and 10 are united with a sloping portion 1I adapted to lie in a plane substantially parallel with the sloping face 44 of the door embossment but spaced therefrom a short distance, as indicated at 12, thereby allowing for any variations in the positioning of the door in relation to the frame. The integral portion 35 of the at 13, for the purpose of saving weight and the lower sloping bottom floor plate I6 is coped out as indicated at 14 in order to straddle the-said triangular extension 36.

Referring now to the construction shown in Figs. 6 to 10, inclusive, wherein the parts entering into the construction of the frame and door are formed of forged or metal parts pressed to shape and welds employed to obtain unitary structures. In said drawings the centersill construction is indicated at I00, the hopper con-' struction at IN, and the frame structure which consists of a lower stirrup-shaped portion I02 and an upper angle-shaped member lower and upper members are welded together as indicated-at I04 and I05 respectively. The stirrup portionis preferably formed of a commercial T-shaped section and includes inner and outer substantially vertically disposed portions I06 and I01 respectively, and a lower horizontal portion I08. At the inner end of the frame the upper part of the T-shaped portion I06 is sheared off as indicated at I09, to correspond to the inclination of the top member I03, and the weld I05 is made between the two parts. The outer leg I01 of the frame is coped out as indicated at IIO to conform to the shape of the angle I03, and the weld I04 is effected along both flanges of said angle I03, the united parts thus forming an integral frame extending around the four sides of the discharge opening. Welded to the underlying flange III of the top frame member are a pair of hingebutts II2, said hingebutts being preferably formed of drop forgings and welded to the said flange III, as indicated at II3. A portion of each forging IIZ extends be yond the angle frame section, as indicated at II4, for the purpose of increasing the bearing area of the frame and providing greater stability for the parts.

At the lower portion of the frame and centrally thereof there is provided a keeper II5 which includes a triangular shaped portion IIS and a projecting hook shaped portion Ill. The keeper member also includes a flange portion II8 which is welded to the upper face of the horizontal beam portion I08 of the frame structure. the center portion thereof is depressed, as indicated at I I9, in order to permit the keeper membet to extend beneath the hopper floor, as indicated at I20, it being understood that the hopper floor sheet I2I is coped out, as indicated at I22 (Fig. 10), for the purpose of straddling the said triangular shaped portion H6. The arrangement of the lower stirrup-shaped section, in combination with the upper angle-shaped member and the hingebutts and keeper means all welded in a one-piece unit, provides an integral rigid construction interchangeable with the cast steel member described in connection with the embodiment shown in Figs. 1 to 5 inclusive.

The door I23 includes a flat body portion I24 flanged upwardly on four sides, as indicated at I25, to provide a pan-shaped door which, when in closed position, encloses the four sides of the frame. Extending upwardly above the body portion of the door is a box-like pan-shaped embossment I26 which is formed with a flat panel portion I21 of generally triangular shape connected to the main body portion of the door by sloping offsets.

The door is pivotally supported on the hingebutts by means of forged hinged pieces I28 which are welded to the door as indicated at I29. The door is perforated, as indicated at I30, to accom- I03, said' modate the projecting hook-shaped portion II 1 of the keeper. To maintain continuity of reinforcement there is provided on the outer side of the door a reinforcing member ISI, consisting of a plate member having portions I32 and Ill overlying the panel portion I21 and the adjacent connecting wall section I54 and welded to the said respective wall sections, as indicated at I35 and II. Extending outwardly from the door, the said member III has a rigidifying flange I" extending lengthwise of the embossment for an appreciable distance on each sideof the perforation I30. The reinforcing member is slightly raised, as indicated at I38, around the margins of the perforation I30 to provide bearing area and strength. Mounted within the said embossment is a latch bar II! and a latch dog I40, said latch bar being pivotally mounted adjacent one corner of the embossment as indicated at I. The latch dog is pivotally mounted, as indicated at I42, and is adapted to have cooperating engagement with the swinging end of the latch. At the pivotal end of the latch bar, there is disposed a plate I43 which overlies the latch bar and is welded at I44 to the bodysection of the door plate, said plate being in effect substantially a continuation of the outer plane of the main body of the door. The pivot I for the latch I30 is a rivet which extends through the plate I43 and through the panel portion I21, the latter being indented as shown at I45 to provide space in which the head I46 of the rivet is contained.

Adjacent the swinging edge of the latch, there is disposed a plate-like member I41 which overlies the latch bar I39 and the dog I40, said member I41 being riveted to the main body portion of the door, as indicated at I40, and adjacent its upper portion forming a support for one end of a rivet I45 constituting the pivotal mounting for the dog I40. The member I41 has a lateral projection I50 for cooperation with a projecting portion II of the latch in combination with a removable bar, as indicated conventionally at I52, for lifting the latch. The member I41 is also provided with an outstanding lug portion I55 formed with a perforation I54 adapted to receive a removable bar (Fig. '1) for forcing the door to a closed position.

. Rearwardly of the-latch bar and dog, the panel I21 is formed with a depressed portion I55 which forms a guiding wall for the latch and dog, and serves to space said members from the main body of the panel, said indent also forming a reeggs for the reception of the head I56 of the rivet The attainment in a completely assembled structure of a door framing having means for attachment to the car structure, framing for the four edges of the door opening, hingebutts for the door, and integral keeper means, in combination with a door hinged to the framing and having selfcontained latching means for coopcrating engagement with the keeper on the frame, is a great advantage in the construction of railway cars, inasmuch as the door framing and door parts can be completely assembled and fitted together prior to application to the car.

The improved door construction including an embossment of triangular shape with one connecting wall of the embossment extending contiguous with the swinging edge of the door and having another wall extending in substantially a diagonal direction, provides for reinforcement of the door along the lines of maximum bending tendency and provides for strengthening of the door adjacent the door mechanism.

while I have shown the triangular-shaped embossment in combination with the door latching means contained therein, it will be appre- .1,

depth thereof; a pivoted latching dog also lying in said embossment and cooperating with the latch for retaining the latter in position; and a guide member overlying the latch and dog, said guide member lying against the plate-like body portion of the door and secured thereto, said latch and dog being provided with lateral projections extending beyond the guide member.
