This invention relates to a door arrangement for railway cars and has particularly to do with the door supporting mechanism. The principal object of the invention is to provide a door supporting device wherein the door may be lifted and temporarily supported upon a door-retaining member, which latter may then be forcibly moved to complete the closing of the door and be thereafter 1o locked in position to positively hold the door closed. Another object is to provide a door supporting mechanism wherein the support` ing member may be moved bodily in one direction to effect closing of the door, and be then moved in another direction into final en gagement with the door. Another object is to provide a door supporting mechanism wherein the door-supporting member' is so interlocked with portions of the door as to prevent accidental displacement of the supporting member in any direction, the mechanism at the same time being constructed for ready disengagement of the supporting member when desired. Another object is to provide a door supporting hook mounted upon an eccentric member, the latter being capable of rotating through a limited arc for imparting a raising or lowering motion to the hook and the door supported thereby, and being also capable of thereafter rotating through a v further arc to cause the supporting hook to forcibly engage with or disengage from the door. A still further object is to so interlock the eccentric member and the door-supporting lock that after a predetermined lifting movement of the lock has been effected through the eccentric motion, a continuation of the rot-ation of the eccentric member will cause a rotation of the lock and thereby force it into positive engagement with the door. Another object is to incorporate positive door releasing means with the door supporting mechanism. A still further object of the invention is to provide a. specially constructed door-supporting hook, also in combination therewith, specially arranged means on the door for cooperation with the same. lith such general and other more detailed objects in View, the invention consists of the construction, combination and arrangement of parts as herein described and particularly p claimed.

In the accompanying drawings, which show a preferred embodiment of the invention, Figure 1 is a fragmentary side elevational View of a portion of a car having a swinging door applied thereto, and in conjunction therewith a door supporting mechanism c0nstructed in accordance with the principles of the present invention.

Figure 2 is a cross sectional view taken through a portion of the door supporting mechanism on the line 2 2 of Figure l.

Figure 3 is a horizontal cross sectional view taken through a portion of the car and the door supporting mechanism on the line 3-3 of Figure l.

Figure 4: is a fragmentary side elevational vievv similar to Figure l, but showing the door in a position not fully closed, the door supporting mechanism being in the position it occupies when the door is temporarily supported upon the door lock preparatory toactuation of the latter to effect complete closing of the door.

Figure 5 is a vertical cross sectional view through a portion of the car adjacent the door supporting mechanism, showing the door supporting lock in a position corresponding to that of Figure 1. The plane of this section is indicated by the line 5 5 of Figure 1.

Figures 6, 7 and 8 show a modified form of the locking faces that are formed upon the door,.with corresponding modifications in the lower end of the door supporting hook, Figure 6 being a side elevational view of a portion of the mechanism, Figure 7 an end elevational view thereof, and Figure 8 an inverted plan view of the saine.

Referring to these drawings, the side of the car is indicated by the numeral l, and 2 is the bottom edgeof the car. A reinforcing member, such as 8 is frequently used along the lower edge of the car side to stiffen and strengthen the same. Rivets such as i are used to secure the stiffening member to the car side.

The car is supplied with a swinging door 5, which is hinged at 6 to the bottom of the car, and in the present embodiment closes upwardly against the lower edge 2 of the car side and the reinforcing member 3. The door is preferably provided near its free edge with a reinforcing member, such as the angle 6, which preferably extends somewhat outside of the plane of the car side so that it may be utilized for securing thereto a seat for the door supporting mechanism to be described.

Secured to the side of the car by means of the rivets 7 is a bracket 8. This bracket has outstanding from it a cylindrical spool 9 which serves as a trunnion or pivot for a rotatable member 10 positioned upon it, the inner face of the latter bearing against the outer face of the bracket 8. This rotatable member 10 is formed in eccentric fashion with respect to the trunnion 9 as a center of rotation, and upon the eccentric outer periphery 11 thereof is journaled a door sulnporting` hook or lock 12. Under certain conditions, this lock may swing freely with respect to the periphery 11 of the rotatable member 10, but under other conditions this swinging motion is arrested. This will be hereafter described. The rotatable member 10 is provided with an arm 13, which extends substantially radially from the central portion of the rotatable member, and secured to this arm by means of the rivets 14 is a lever extension 15. This lever may be utilized for forcibly rotatin the member 10 about the trunnion 9 as an axis of rotation. The bracket 8 is provided with notched po tions 16 into which the lever 15 will seat at definite angular positions of the lever, thereby holding the lever and the rotatable member in predetern'iined positions. 1n order to move the lever it is necessary to spring it outwardly to clear the notches.

' Vifhen in horizontal position the lever holds the rotatable member' and the door lock 12 in position such that the door lock is in positive or final engagement withthe locking face of the door. rEhe lever is shown as occupying this position in Figure 1. The other notch 16 is arranged to hold the lever 15 in a vertical position, such as indicated in Figure 4;, and

when in this position, the door lock 12 is ready for temporary engagement with the locking ace of the door when the door has been lifted to partially closed position.

The door supporting` lock 12 is placed in position upon the periphery 11 of the rotatable member 10 from the rear face of the latter. A rivet 17 passes through ran openingl piercing the center of the spool 9, and also through aligned openings in the bracket 8 and in the car side 1, and if desired, in the reinforcing bar 3. This rivet passes through a washer 18 at the outer end of the spool 9, the washer beingof sufficient size to slightly overlie the outer face of the rotatable member 10 around the periphery of the opening therein that is utilized for journaling the rotatable member upon the spool 9. The length of the spool 9 is such that when the washer 18 is clamped by the driven 17 against the outer end thereof, the intervening space between the inner face of the washer 18 and the outer face of the bracket 8 will be slightly greater than the thickness of tl e rotatable member 10. The member 10 will thus be retained in position between the bracket and the washer 18, and will have the necessary freedom of movement for therotation desired. f

1t will be' noted that the hook 12 being entered as aforesaid upon the periphery 11 of the rotatable member from the rear of the rotatable member-will also be retained in position by the driving of the rivet 17. The arm portion 13 of the rotatable member 10 extends along the outer face of the hook 12, so that this arm, together with an annular flange 19 formed around the outer edge of the periphery 11 of the rotatable member, prevents the hook 12 from moving outwardly with respect to the rotatable member, which latter is in turn restrained from outward movement, or movement away from the car side, by means of the rivet 17 and washer 18. The outer face of the bracket 8 retains the hook and the rotatable member against inward movement, or movement towards the car side.

rthe hook 12 is accordingly free to swing parallel with or alongside of the ear side, around the periphery 11 of the rotatable member a center of rotation. But this rotary movement is restricted to certain limits which will now be described;

1t will. be noted that the rotatable member 1() has formed upon it lugs 2O and 21, which are arranged to contact with portions of the hook 12 when the parts are in certain predetermined positions. rThe device is shown in Figure 1 with the lug 2O bearing against the rear edge of the hook, and with thehook in full engagei'n'ent with the locking face of the door, and with the lever 15 locked in the horizontal one of the notches 1G. lt will thus be seen that so long as the lever 15 is seated within the horizontal notch 16, as shown in this ligure, the hook 12 'cannot swing rearwardly or become disengaged from the door, because of the Contact between the back of the hook 12 and the lug 20 of the rotatable member.

1n Figure et the lever is shown in fulllines in an upright position and within the vertical one of the notches 16. fillien in this posit-ion, the lug 21 is in contact with the forward edge of the hook 12. 1n this view, the door is shown s not fully closed, and in only temporary engagement with the hook 12, the preliminary locking face 23 of the door being shown as resting upon the preliminary supporting ledge 22 of the hook. In this position of the rotatable member, the hook is free to swing to the right, or away from the angle G andthe locking face on the door, the lug 20 beingentirely removed from behind the rear edge of the hook. The freedom of the hook to swing rearwardly is desirable in order that when the door is lifted, as by hand, the contact of the angle 6 with the approach portion 24 of the hook may cause the latter to swing to the right to permit continued upward movement of the door. Subsequently, when the locking face 23 is clear of the supporting ledge 22 the hook may fall by gravity into the position as shown in Figure 4, where the door will be supported in a position preliminary to iinal closure.

The lever 15 being in the position illustrated in Fig. 4, is rotated clockwise in order to effect complete closing of the door. During the first portion of this rotation of the lever 15 and of the attached rotatable member 10, the hook 12 will be lifted bodily in a substantially vertical direction, due to the eccentric relationship of the hook and the rotatable member. This rotation of the lever 15 being continued until the parts are almost in the position shown in Figure 1, the lug 2O will come into contact with the back of the hook 12. Thereafter the hook 12 is interlocked with the rotatable member 10 so that these two members rotate in unison or harmony, the lifting motion of the hook being arrested and the lower end of the hook being swung forcibly to the left, into full and complete engagement with the locking face of the door, or into the position as shown in Figure 1.

It will be understood that the lever and lug. arrangement just described affords a means for applying impacts to the hook to force it into the fully closed position desired. In this fully closed position, the preliminary locking face 23 seats Within the final supporting ledge 26 on the hook, so that in order for the hook to be released it is necessary that a relative vertical displacement take place between the hook and the door, the horizontal plane tangent to the face 26 being lower than the corresponding tangent plane of the face 22.

Nhen it is desired to release the door the lever 15 is sprung outwardly until freed from the notch 16, and is then rotated in counterclockwise direction. This rotation, through the eccentric action heretofore described, lowers the hook and the door until the lug 21 comes into contact with the forward edge of the hook 12. Further movement of the lever in counter-clockwise direction now produces a positive rotation of the hook 12 in harmony with the rotation of the lever, so that the lower end of the hook may be forcibl swung to the right and thereby disengaged fiom the locking face of the door. It will be understood that to effect this the lever 15 may be swung in counter-clockwise direction somewhat further to the left than shown in Figure 4, if desired. The lever 15 and lug 21 may be utilized for impact against the front face of the hook for forcible disengagement, if necessary.

The locking face on the door is preferably formed by riveting to the angle iron 6 a bracket 27 which has cast upon it the locking shoulder 23 before referred to. The hook may be formed with a shroud 28, which ties the supporting ledge 26 to the upper portion of the hook in a substantial manner. This shroud overlies the outer end of the bracket 27 and prevents movement of the lower end of the hook towards the car side. The shroud 28 connects the lower shank portion of the hook to the upper shank portion and forms a rigid tension tie between the door supporting, ledge 23 and the upper end of the hook, thereby carrying the load of the door directly from the ledge to the pivot eye of the hook without inducing heavy bending movements in the shank portion of the hook. Being arranged outwardly of the end of the angle iron 6 and outwardly of the hook seat, the shroud 28 will not interfere with the free vengagement of the hook and the door arm lto seat between a pair of walls 31 formed on this casting 29, there beinga suitable space between the walls to receive and accommodate the lower end of the hook. These walls terminate at the top in inturned shoulders 32, beneath which the laterally extending supporting ledges 33, which are formed upon the opposite sides of the hook 12, may be seated.. The ledges formed beneath the shoulders 32 are shaped in a manner similar to the locking face in the previously described arrangement, there being preliminary points 34 which will first rest upon the ledges of the hook for retaining the door in partially closed position.

In this construction when the hook is in position between the walls 31, it cannot be vents swinging movements of the hook. Fur i r thermore, the difference in elevation of thi` points 22 and 26 with relation the seat 23, makes it impossible for the door to become disengaged from the hook, except when such disengagement is desired.

T have thus described an embodiment of my invention. Other embodiments, within the scope of the appended clain'is, are contemplated without departing :from the spirit thereof.
