CAR-DOOR MECHANISM.

Application filed August 26, 1925.

My invention relates to door mechanism which is especially suitable for application to the doors of gondola cars where the side sheet of the car is offset inwardly to form a hopper, but it is to be understood that the construction may be adapted for use with any form of car where the edge of the door is located inwardly with respect to the car side.

The principal object of the invention is to produce a car door mechanism provided with means for enabling the door to be readily lifted to a preliminary position of closure. Other objects of the invention are to produce a simple and eflicient form of door arm which may be readily combined with a flanged metallic door and with a door supporting member adapted to cooperate with a pivoted hook mounted upon the car body.

The primary feature of the invention, generally stated, involves the combination with a hinged door having its free edge spaced inwardly from the plane of a portion of the car side, of a door arm secured to the door extending outwardly beyond the free edge of the latter, a hook pivotally mounted on the car body, and a flanged member mounted on the door for cooperating with the hook to sustain the door against an opening movement, the flanged member being in overlapping relation to the door arm and projecting beyond the free edge of the door, but terminating inwardly of the outer end of the said arm.

Another feature of the invention consists in formin. the door arm as a channeled member W ose web is secured to the door and whose flanges project outwardly therefrom, and in securing to said. channeled member a short section of angle iron which extends beyond the free edge of the door so as to form a seat for cooperating with a door supporting hook pivotally mounted upon the car body, one of the legs of the angle iron being secured to one of the flanges of the channeled member, and said channeled member extending outwardly from the free edge of the door beyond the outer termination of the angle iron.

A still further feature consists in the combination with a hinged door having an out Wardly projectin marginal flange, of a door arm secured to t e door, a door supportin member overlapping said arm and secured thereto and extending outwardly beyond the marginal flange of the door, and a. has];

pivotally mounted on the car body so as to cooperate with the door supporting member for retaining the door in closed position, a portion of the marginal flange of the door being bent to form a recess through which the said door arm and door supporting member extend.

Other features of the invention pertaining to advantageous forms and relations of parts will hereinafter appear and be pointed out in the claims. Q

In the drawings illustrating a preferred embodiment of the invention,

Figure 1 is a side elevational view of a portion of a gondola car equipped with door mechanism involving the invention.

Figure 2 is a detail sectional view on the line 2-2, Fig. 1.

Figure 3 is a perspective view showing a portion of the mechanism.

The gondola car illustrated is formed with a side sheet 1 which is offset inwardly, as indicated at 2, to form a hopper, the lower part of the side sheet being vertical .and having a stiffening angle 3 riveted thereto. One of the side stakes commonly employed in cars of this type is shown at 4. These features are well known and require no extended description. V

The door 5 for closing the lading discharge opening at the lower end of the hopper connected to the car body by suitable hinges (not shown) in the well known manner so as to swing to open position under the influence of gravity, the hinge axis of the door being in the direction of'the length of the car. The door is preferably of the sheet metal type having marginal stiffening flanges 6. The marginal flange 6 along'the free edge of the door remote from the hinge axis is bent or pressed outwardly toward the plane of the door, as indicated at 7, so as to form a recess for receiving a door arm 8 and the angular door supporting member 9 attached to the latter.

Secured to the outer face of the door and extending outwardly beyond the free edge thereof is a door arm 8 which is preferably of channel form produced by pressing a metal plate or blank of suitable shape. The web of the channeled door arm contacts the outer face of the door 5 and its flanges 10 project outwardly therefrom. Adjacent tlie free edge of the door the arm 8 inclines downwardly and outwardly, as at 11, so as to pass threugh the recess '7' tenses. in the marginal flange of the door. The outer end of the door arm is preferably formed as a horizontally extending portion 12 terminating well beyond the free edge of the door and spaced downwardly from the plane of said door. The portion 12 of the door arm thus provides means which may be readily grasped by the trainman for the purpose of lifting the door to a preliminary position of closure.

Pivotally mounted upon the car body inwardly of the outermost part of the side sheet 1 of the car is a .door supporting hook 13 which swings in a plane intersecting the adjacent door arm 8 with which it is asso ciated. Two of these hooks are preferably employed for supporting each door 5, each of said hooks being associated with a cooperating door arm 8 and door supporting member 9, as shown in the drawings. The hooks are preferably of the so-called twostep type, each having an upper shoulder or ledge 14 for supporting the door in fully closed position, and a lower ledge 15 for cooperating with the adjacent angle iron 9 carried by the door to maintain the latter in partially closed position. Pivoted cams 16, which respectively cooperate with the hooks 13, serve to prevent the latter from accidentally moving to unlocked position. Brackets 17, through which the rivets forming pivots for the hooks and cams pass, preferably overlie the latter so as to preserve their pivotal axes in proper spaced relation.

The members 9 which are carried by the door for cooperating with the hooks 13 to support the door against opening, may advantageously be formed as short straight sections of angle iron whose horizontal flanges 18 provide shoulders or seats adapted to cooperate with the ledges 14 and 15 of the respectively adjacent hooks 13. The vertically extending flange 19 on each of the angle irons 9 is riveted to the adjacent flange 10 of theneighboring door arm. The door supporting member 9 extends through the ad acent pocket or recess 7 in the neighboring marginal flange of the door and its outer end terminates inwardly of the outer end of the associated door arm 3. llhe horizontally extending leg 18 of the angle iron is notched or cut away as indicated at 20 to permit the hook 13 to swing to fully locked position.

To enable the door 5 to be forced from partially closed to fully closed position by the aid of a removable lever or prying bar, a fulcrum plate 21 is riveted to the car body intermediate of the hooks13. By inserting a suitable bar or lever through the aperture 22 in the fulcrum member 21 so that its inner end presses upwardly against the door 5, the door may be readily forced to fully closed position after it has been temporarily supported upon the ledges 15 of the hooks.

In closing the doors the trainman pulls upwardly upon the outer end portions 12 of the door arms 8 until the door has been raised sufficiently to permit the lower shon ders 15 of the hooks to seat beneath the hori- 5 secured to said door and extending outwardly beyond the free edge of the latter, said arm being inclined downwardly and outwardly adjacent the free edge of the door. a door supporting member carried by said door and projecting beyond the free edge thereof and terminating at its outer end between the door and the outer end of said arm. and a hook pivotally mounted on the car body for cooperating with said door supporting member to support said door against opening.

2. A car door mechanism involving, in combination with a hinged door, a flanged door arm secured to said door and. extending outwardly beyond the free edge thereof. said arm intermediate itsends being inclined downwardly so as to space its outer end away from the plane of the door,'a flanged member. and a hook pivotally mounted on the car body and adapted to cooperate with said flanged member to retain said door in closed position, said member having flanges disposed at an angle to each other, one of said flanges overlapping and being secured to said arm, and one of said flanges forming a seat for engagement'by said hook.

3. A car door mechanism involving, in combination with a hinged door, a chan neled member secured to said door and extending outwardly beyond the free edge thereof, the web of said channeled member being secured to said door, a door supporting hook pivotallv mounted on the car body, and a flanged member mounted on said door and extending beyond the free. edge thereof and adapted to cooperate with said hook to' retain the door in closed position, said flanged member having a flange secured to one of the flanges of said channeled member and having a portion forming a seat for said hook, and said channeled member extending outwardly from the free edge of the door beyond the outer end of said flanged member.

4. A car door mechanism involving, in combination with a hinged door, a channeled member having its web secured to said door and its flanges projecting outwardly from the plane of said door. said channeled member being downwardly and outwardly inclined adjacent the free edge of the door and extending outwardly beyond said free edge, an angle iron secured through one of its legs to a flange of said channeled member and its other leg constituting a seat for cooperating with a hook member. and a hook member pivotally mounted on the car body and adapted to engage said seat to retain the door in closed position, the said channeled member extending outwardly beyond the outer end of said angle iron.

5. A car door mechanism involving, in combination with a hinged door having an outwardly projecting marginal flange, a door arm secured to said door, a door supportin member overlapping said arm and securer thereto and extending outwardly beyond said flange, a portion of said flange being bent toward the plane of the door to form a recess receiving said door supporting member, and a hook pivotally mounted on the car body and adapted to cooperate with said door supporting member to retain the door in closed position.

6. A car door mechanism involving, in combination with a hinged door having an outwardly projecting marginal flange at its free edge, a door arm secured to said door and extending outwardly beyond said edge toward the side of the car, a door supporting member overlapping said army and secured thereto and extending on opposite sides of said flange. a portion of said flange being bent to form a recess through which said arm and door supporting 'member extend, and a hook pivotally mounted on the car body and adapted to engage said door sup porting member for maintaining said door in closed position.

7. A car door mechanism involving, in combination with a hinged door having a marginal flange, a channeled door arm secured to said door and extending across said flange, a portion of said arm adjacent said flange being inclined, said flange being bent to form a recess for receiving said inclined portion of the arm, a door supporting member carried by the door and extending on opposite sides of said flange, and a hook pivotally mounted on the car body and adapted to engage the door supporting member to support said door against opening.

In testimony whereof I aflix my signature.
