Specification of Letters Patent, atggtged N317., 19* @D Application filed August l, mit). Serial No. 574,935.

To all whom it may concern:

Be it known'that I, HEXRY A.-CHn1sTY, a

citizen' of the United States, residing atdoorway opening and one or more closable ports for the entrance and delivery 0I lading similar to grain, coal and the like.

It; has been'customary and usual heretofore to provide railway cars with an outside door and with a supplemental or additional grain door which is of use only when the car is transporting grain. These ordinary outside doors are subject to considerable danin age and injury owing to their exposed condition, their proper operation is not infrequently interfered with because of climatic conditions, and when damaged or iinproperly supported on the car side they are frequently a menace to the safety of passengers in cars `traveling on adjacent tracks, because they are subject to displacement by winds and the like.

@ne of the objects of this invention i.: to provide foreach door opening a single door Which will perform the function of the ordinary outside door and also be' suitable for use as a grain door.

In order that those skilled in this art may have a 'full and complete understanding ot I the invention, I have illustrated a preferred and desirable embodiment of the saine in the accompanying drawings formingr a part of' this specification, and throughout the varions views of which like reference characters relier to the same parts.

in' these dra wingsf-Figure lv shows a fragment of a car doorway :ind illustrates in elevation the outer face ot a metallic door embodying the tentures ot construction and advantage oli' this invention; Fin'. 2 is a vertical .section through the door on line 2 2 of Fig. 1'; Fin: fl is-an elevation ot n forni and .style of locking or tightening:

By reference to these drawings it. will apparent that the main car door, which of suicient Width and height to close the entire doorway 15 ot' the ear, is composed of two metal plates 16 and 17, the lower 16 of which is of heavier construction and ot' greater thickness than the upper plate. As is perhaps more clearly shown in l? 14, these tivo plates, at their junction, are

Y is

4overlapped and secured together by a of rivets i8, which, together with a. row ofrivets 19, also fasten to the o face of the door a holloirir stiening har strip 20, bent or shaped to have-a central longitudinal rib, as is clearly illustrated. Along each vertical edge, this door is equipped with an angle har 21 at the front edge, and with an angle bar 22 at the back edge, the niain plate or sheet of 'the door being disposed in front of one flange of each of these hars, while theV other iianges ot the hars project outwardly, as is clearly indicated in Figs. t) and l0. Alongl its top edge, the door is provided with a smaller, stiftening' angle hai' 23 resting` against the outer face ot' the door and having one flange extended outwardl as shown erhans more clearly in Pig. ll. below this-liar the door is also supplied, on its outer/face, with aoother .stitl'eninior strengthening angle hart, :ind is turthcrequipped with n phiralit 2t?, fastened tothe door in the usual manner, hy means ot rivets, and constructed siniihii.' n.. on

' main door and the closure for the lower l to the nienihci no.

.LOU

As is shown in Fig. 8, the cai" floor at the doorway opening is supplied with a rarl 29 having a suitable base 30 on which the lower edge of the plate 16 rests and is adapted to l" provided with an opening or port 31 of substantial size, such opening extending up wardly from the bottoni edge ot the door. This port is supplied for the purpose of permitting a ready discharge ol the grain or other similar lading, and obviously it is necessary to provide the same with some sort of a closure or supplemental door which will e'tlectively and securely prevent leakage ofthe grain or other lading. To effect this result l use a metal plate 33 somewhat longer and also somewhat wider than the opening 31 which it is intended to close, and l.' fasten such plate or door 33 to the main door by a pair of chains or cables 34, the construction being clearly illustrated in the various figures. The lower edge. of the plate or supplemental door 33 is bent inwardly slightly at 35 and is adapted when the door is closed to be disposed inside of the rail 29, the excess length of vthe plate 33 for the accomplishment of this result being cut off, will be readily understood. Along its lower edge, the plate has riveted thereto a curved strip 3h adapted to overlie and be disposed outside of the rail 29 in the closed position ot tb door, shown in Fig. t3. Near its top e fe and extended longitudinally of the platt 0" the latter has fastened thereto an angle bar 37, the lower flange of which projects or extends outwardly, as.

shown.

Just below the stiffening rib`23, the main vdoor has riveted to its outer face an outstanding, depending shield or apron 38 adapted to cover and protect an eccentric shaft 39 rotatable or oscillatory in a plurality of strap bearings 40 riveted to the cuter surface of the door beneath the apron 3S, one end of such eccentric shaft having a laterally bent-handle 41 with an apertured end 42 adap 'ed to receivev a staple 43 in the closed position of the supplemental door 33, the staple in turn being intended to receive a holding pin 44, which, if' desired, may be al at lVhen the lower edge of the 3?- stri-lddles the rail 2t) and the door is in closed position, the eccentric portions of the shaft 39, by coaction with lthe stiffening angle bar 3T, act to forcibly press the upper edge of the door against the outer face of the main door beneath the shaft, as shown in Fig. G, and, due to the great leverage secured by the handle 41, the secure and tight closure of the supplemental or auxiliary door niay be effected with little effort. The outer I face of the plate 33 has fastened thereto for its manipulation a pair of handles 46 which are adapted to take over a pair of hooks 47 on the inain door when this auxiliary door is hung up in open position, as shown in Fig. 8. To secure a tight or grain-proof joint between the vertical edges of the plate 33 and the corresponding parts of the main door, the edge portions of the plate 33 are crimped, as shown in Fig. 5, at 4S, forlthe reception of half-round bars 49 fastened to the plate 16 along the vertical edges of the opening 3l. Clearly, then, when the door is pressed honie to'closed position, no grain, coal or similar lading can leak around the vertical edges, The main car-door also has an upper port or loading opening 50 of rectangular forni, of substantially the same length as the low-er port, but. preferably ot somewhatgrea'ter width, whereby to permit the ready entrance of a person through such opening into the car-body. In order to close this upper port, I supply the door with an# other auxiliary door or plate 51, the lower edge of which is adapted to be held in closed relation and overlapping the main door by ar plurality ol brackets 52, shown in detail in Fig. 12, such brackets being adapted and intended to receive the lower 4edge of the door 51 between themselves and the outer surface of themain door-plate 17. At its upper edge, the plate 51 is bent to provide a roll or hollow finishing bead 52, which acts both to stiften the plate and to do away with a raw and sharp edge along the top of 'i the door. The upper portion of this supple mental door 51 is adapted to bear against the inner face of theinain door plate 17, as indicated in Fig. 11, and is held in contact with such inner surface by the end parts oo of the plate 51, which form prolongations or extensions of hollow ribs 54 along the vertical edges of the plate 51, such ribs accommodating half-round bars 55 on the plate 17, which construction is similar to that dcscribed above in connection with the lower door 33. These fingers or projections 53 overlap the vertical flange of the angle bar 24, and consequently actI to maintain the,

has a. single central handle GO, the lattere'ii .13

ing of especia-l use for grasping when'thr ltlt) assist in maintaining e grain-tight relation between the vertical-edges of the door and 'shaped metal strip t5? adapted to secure a member T4 fastened to the outer face of the ,door 5l has been first freed 'trom-the hasn @weee operator wishes to enter the ear through the upper opening. In order to prevent unau-k thorized opening of this upper door, it can he supplied with one or more staples 6l cooperating with hinged straps 62 fuloruned' at 63 on the main door, the holes through such straps being adapted to receive the staplesl Gl, through which may ne passed the .Securing pin 64, which, it preferred, may he sealed at 4654 ln order'to maintain the door in proper grain-tight relation With the side wall ot' i the ear, the latter, .on the inside of thevcar, above the doorway opening l5, has fastened thereto a plurality of straps or brackets (SG overlapping the top edge of the door and-its inner tace, es will be readily understood, acting to holdthe' door down in place and to hold it laterally in opereitive relation with the side wall of the ear. ln order to the car sideovall, the forward edge oi' the doorway is supplied or equipped with a V .vedging action with a small flange titl on 'the outer edge of angle har Q1.. The other ver tical-edge of the door *ay has fastened thereto a wedge strip (Si) which coacts in a similar manner with a small flange T0 on the edge of angle har 22, it 'being understood that in order to open the door it is moved in the direction indicated .by the arrows in Figs. l, 9 and l0.

s a supplemental or additional holding means ltor the main door. l may use, if found necessary' or desirable, a damping mechanism shown in Figs. ,B and` Ll, which comprises e level` 7l ulcruined to the doorway 'casing at T2, and having a curved wedge arm 73 adapted to coact with .a wedge door, sueh member 74 having an undercut part l5 for the accommodation ot the end of the arm 73. lVhen this lever Tl is turned on its fulcrlun to the right. as the parts are viewed in Fig. 4l, it draws the door 1G, l? outwardly into tight relation with the side wall ot' the ear and also acts to torce the door downwardly against vibration or possible vertical displacement or jarring'. Suitable means 76 may he provided for holding the lever Il in cooperative and binding relation to its companion member 74.

To fill the eer with grain or other similar ladingihe door 33 is maintained closed and the door 5l is opened b vgrasping .the pair ol y handles 59 and pushing the same upwardly, the fingers or projections 53 hearing against the vertical flange-,oiI the angle fl. rlhis slight upward movement, assuming that. the

or catch G2, permits it to be pulled o ut- Wardly beyond the supports 52, in .which position it can he readily lowered Wholly i l i; l l i l away Jfrom the opening` 50, being supported by the Sshaped loops 57 which slide on the hars 56. The grain may then be introduced through the opening 50 into the ear in auf;r approved manner, spo-nts projected through this upner port or opening. The car having; heen filled to the .desired height with the lading., the door 5lv is pushed upwardly, the loops 57 sliding` on the bar 56, and the upper edge of the door 'i 1s made to overlap both the inner and outer surfaces of the plate or door sections 1G, as shown in Fig. 1l, thereby holding the up- 'ner edge of the door securely against inner or onter displacement. i the door is raised suliciently to perinitit to he slipped over the brackets 52, which hold it effectively in grain-tight relation 1with lthe outer surface of the' plate or door see- The lower edge of S as through one or more g tions 17. It may or may not he locked in 8T place hy using the elements (il to 65, inclusive. l/Vhen it is desired to unload the' car of the grain, the operator pulls ont the-A pin est, having first broken the seal Llftl, and

thereby releases the handle permitting if the saine to be swung upwardly'sutlieientlv to :treo thelower door or plate 33 from the eccentric portions of the shaft 40.

Owing to the pressure of the `grain, the

door swing-s down to the position Ashown in if {"ie. T, 'this travel being' limited hy the p eir of chains 3l. The grain, of con se, in this };esiti n of the door, pours over its top edge and around its end edges. The operator van non' lift the doo' and hooks l?, as shown in Fig. S, iliern'iitting a l'ree and unohstruete-l flow or discharge'of the lading through the opening Ill.. In oi'- tler to use this car door as an ordinary door is' used, for opening and closingr the doorway l5 in the car-hotly sidewall, it is nec; essary to have both of the'supplementary doors --ll and 5l in closed position, as shown in Fig. l, and', under these conditions, thisl door may he readily slid on, the hase BOot' the rail to open position, 'the upper 4end ot' tho door being),l guided in this sliding action by the l) ackets 66. (lt course, in order to etlert this slidinzsg,l opening" of the door, it is' y its companion cooperating inemher lil, if these parts aroused on the ear. 'illhen theA main door is slid haelt into elosed relationl with the doorway, the tivo flanges 68 and T0 engage the wedge plates til end (it), the cooi'zcration ot these norte tending to move thehole door lat :a sidexvise into firm enagement. with the side well of the car, iereov preventing any leakage or loss of ie ladine` it the letter is nall particles like grain. I lo those skilled in this ert it will he ep'- narent that the combination door which l have invented and constructed is of simple torni, is "economical to manufacture, is not 2 hung it on the? l in the forni ofA -l readily damaged, is strong and rigid, and ,the parts thereof, owing to their attachnient to the main door, cannot become lost or misplaced, as not infrequently occurs with thegrain doors ordinarily in use in `cars already equipped with doors oi a size suli'icient and' adapted to close the entire doorway. This new style and forni of door "takes the place of both the main door and the grain doorsA in ordinary use.

While I have described one particular enibodin'i'ent of the invention, the latter is not necessarily limited and restricted to the precise and exact features and details of construction described and shown, becausetlie invention is susceptible of a variety ofenibtalinients,` and the minor mechanical 'ifea- ,ftures of the door herein set forth may be changed and modified within wide vlimits without departure from the heart or substance Qf the` invention and' without the sacrificeof 'any sabstantia benefits and adlYaritagest4 'i I clainfr:
