CAR-DOOR ARRANGEMENT.

Application filed February 20, 1922. Serial No. 537,675.

To all whom it may oo'ncrn:

Be it known that I, WILLIAM E. WINE, a citizen of the United States,residing at T0- ledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Car-Door Arrangements, of which the following is a specification.

This invention relates to door mechanisms for railway cars or the like and has among its objects to provide a simple form of door securing means, which will be economical of cost and of sufficiently sturdy construct-ion to meet the conditions of the service in which it will be'used. A further'object of the invention is to provide a simple and economical form of door stifiening member for use with a door having a simple form of securing device arranged for association and cooperation therewith.

With such general objects in view, the in vention consists of the formation, combination and arrangement of parts as will be herein described and particularly pointed out in the appended claims.

In the drawings, which show a preferred embodiment of the invention, Figure 1 is a fragmentary side elevational view of the lower end of the hopper of an ordinary twin hopper coal car of the type in general use in railroad service. In this view is shown a door mechanism constructed in accordance with the principles ofthe present invention.

Figure 2 is a fragmentary and elevational view of the same corner of the car as shown in Figure 1. Figure 3 is a transverse sectional view taken through the door securing mechanism, approximately on the line 3-3 of Figure 1. Figure 4 is a transverse sectional view taken through a portion of the hopper and the door mechanism approximately on the line 4-4 of Figure 1. The approximate plane of this section is also denoted by the line A-A of Figure 2. Figure 5 is a longitudinal vertical section through a portion of one of the doors and the door stiffening members, the view being taken approximately on the line 5-5 of Figure 2. Figure 6 is a diagrammatical view indicating the type of car to which the present invention is shown as applied in the preceding figures, the view being in side elevation, and the arrangement of the doors being indicated. Figure 7 is a detached view, in diagram, of a pair of doors as ordinarily used in twin hopper car construction, the center sills of the car also being indicated in this figure, in order to show their relationship.

Referring now to these drawings, it will be noted that the style of car to which the invention is shown as applied is of the twin hopper type, having sides 1 and bottom slope sheets 2. Near the center of the car, the slope sheets terminate so as to form, with the adjacent portions of the sides of the car, a pair of hoppers, with their discharge openings turned toward each other, as indicated in the diagram of Figure 6. The center sills of the car, which extend longitudinally of the same ordinarily out each of these hoppers into two portions arranged side by side. Doors such as l arranged in pairs, are hinged end to end in order to close the discharge openings, door hinges for the same being indicated at 5 in Figures 6 and 7.

It is generally permissible that the doors for both of the hoppers at one end of the car may be operated in unison, and in view of this, it is preferred to connect the adjacent pair of doors at an end of the car by means of a flanged stiffening member 6, which extends transversely of the car from side to side. To this stiffening member both of the doors are secured by means of rivets, or other means, so that the doors are held in a definite spaced relationship by means of these stiffeners. The stiffener is preferably formed of a length of channel iron having one flange thereof lying against the plates of the doors, and with the web outstanding from the door plates. This stiffener is preferably ofless length than the width of the car, so that the ends of the stiffener do not extend entirely to'the line of the car sides. The web of thechannel iron 6 is preferably formed of very thin material and much weight is thereby saved. The thin web, however, is not sufficient to carry the concentration of loads occurring at the points of support of the doors, hence I rivet to the ends of the channel 6 short lengths of angle iron 7, which form extensions to this door stiffener. These angles extend outwardly at each end of the channel to outside the lines of the car sides. One flange of each angle is backed up against the back of the web of the channel and the other flange or leg thereof lies parallel with the outer face of the door plate and slightly spaced away there from and extends in.a direction away from the flanges of the channel. By this means, a considerable increase in stiffness is effected in thevicinity of the edge of the door and the shorter angle iron, being ofheavier metal than the web of the channel, is better adapted to resist the concentrated load of the door-supporting hooks shortly to be described. This construction saves considerable material and is accordingly economical in first cost and is also of greater e'fiicien'cy in particular cases than were a continuous length of a heavier section employed.

= Secured to each side of the car adjacent the endsof the angles is a door securing hook 8, which is pivotally connected to the car side- This pivoting may be effected through the medium of a bracket 9, which lies against the side of the car, the bracket having a suitable spool or boss 13 provided upon its outer face upon which the pivoted end of the hook 8 is positioned. The hook 8 is provided with a locking face 14:, which is arranged to seat behind the upri ht flange 10 of the angle iron extension 7, this flange thereof lying parallel with but slightly removed from the plate of the adjacent door @l, and upstanding from the web of the channel 6. The hook 8 is also provided with an approach portion 11 so arranged that when the door is pushed shut by means of the hand or the foot of the attendant, the

hook will be automatically lifted, and will then drop into locking position, as shown in Figure 1.

In order to prevent the accidental displacement of the hook, aneccentric cam 12 may also be mounted upon boss 13 on the bracket 9. This cam may be turned about this boss as a center in order to forcibly hold the hook in engagement with the door angle. A plate 15 overlies the hook and the cam, and rests upon the tops of the bosses such as 13, thereby forming a space between this plate and the bracket 9 for the free operation of the hook and the cam. Securing rivets such as 16 pass through pierced openings through the centers of the bosses and through the plate 15 and the car side 1, thereby securing all of the parts together. An additional rivet such as 17 may pass directly through the plate 15, the bracket 9 and the car side 1, for additional securing purposes.

The edge of each door plate is preferably turned to form a marginal sealing flange 18 lies alongside the inner face of the margin of the side plate 1, where it defines the hopper opening. The arrangement of the stiffening member 6 with the separable extelr sions 7 overlappingly secured to the ends of the same,respecially with the legs 10 of the latter lying parallel with and somewhat removed from the plane of the door plates, is especially advantageous with this door construction, inasmuch as it combinesgreater efficiency of the door securing member with greater economy in weight and cost.

The door arrangement thus described constitutes an effective means for supporting the doors in a certain and effective manner with the employment of unnecessarily costly parts. The arrangement is furthermore such that the parts can all be constructed of sturdy form and the item of upkeep is practically eliminated. H

I have thus described an embodiment: of my invention. Other embodiments are possible within the scope of the appended claims without departing from the spirit thereof. '1

What is claimed is: p

1.- A door mechanism for railway cars including a door hinged to the car body, a flanged stifi'ening member secured to the door near the free edge of the same, a flanged extension secured to the stifi'emn member, the said extension being formed 0 metal of greater thickness than that ofthe stiffening member, and door securing means pivoted upon the car and arranged for cooperative engagement with the said extension.

2. In a door arrangement for railway cars, a pair of doors hinged side by side to the car body and extending transversely of the same, a flanged stiffening member secured to and connecting both doors, the same being disposed with the flange 'thereof against the doors and extending longitudinally of the doors, near their free edges, arid being arranged to hold the two doors in a definite spaced relationship, the said stifiening member extending for less than the full width of the car, door securing members attached to the car sides beyond the limits of the doors, and separable flanged extensions overlapping and secured to the ends of the said stiffening members, the same extending outwardly beyond the lines of the car sides and being arranged for 00-. gperation with the said door securing memers.
