3 Claims.

' This invention relates to improvements in door fasteners for hinged doors.

a fastener for hinged doors of refrigerator cars comprising a rotary locking bar mounted on the door, cooperating keepers above and below the door with which the keeper engaging means on the bar is engageable to lock the door in closed position, and cooperating interengaging locking means on the bar and top and bottom keepers, respectively, to rigidify the door structure with respect to the car body when the door is fastened in closed position, thereby positively holding the door against weaving.

A more specific object of the invention is to provide a fastener asset forth in the preceding paragraph, wherein the cooperating locking means on the operating bar and keepers comprises a pair of locking lugs on the bar at the top and bottom ends thereof, engageable within horizontally arranged seats formed in the keepers. 7

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming a part of this specification Figure 1 is an elevational view of a portion of the side wall of a refrigerator car provided. with a pair of hinged doors, illustrating my improvements in connection therewith. Figure 2 is an enlarged elevational View of the struc ture shown in Figure 1 at the lower ends of adjacent portions of the doors. Figure 3 is a horizontal sectional View, corresponding substantially to the line 3-3 of Figure 2. Figure 4 is a vertical sectional view, corresponding substantially to the line 4-4 of Figure 2.

In said drawings ll! indicates a portion of the side wall of a' refrigerator car provided with a door opening I I closed by the usual pair of hinged doors l2 and I3. The doors l2 and i3 are supported along their vertical outer edges by the usual hinge members l4M-M which are of well-known design. As is understood by those skilled in this art the hinged doors l2 and i3 are provided with beveled meeting edges, the edge of the door I 2, which is the door last closed, overlapping the adjacent edge of the door I3. It is also the usual practice to bevel the cooperating engaging edges of the doors and the walls of the door opening and provide all engaging edge portions with compressible insulating material. My improved door fastener comprises broadly top and bottom keepers A and B secured to the car wall; a vertically disposed rotary operating bar C mounted on one of a pair of hinged doors; top and bottom keeper engaging crank members D-D on the bar; locking lugs E-E at the top and bottom ends of the bar; seats F-F provided in the keepers with which the lugs EE are engageable; and an operating handle lever G for rotating the bar. v

The keepers A and B are of similar design, except as hereinafter pointed out. As shown in Figure 3, each keeper has an inwardly directed cam slot I5 of well-known design within which the corresponding keeper engaging crank portion of the operating bar is engageable to force the door tightly closed or pry the same partly open. The top and bottom keepers A and B are secured to the wall of the car, respectively, above and below the door opening H, in any suitable manner, preferably by bolts extending through the bodies of the keepers and the car wall It. Each keeper is provided with an outstanding portion it which is upstanding on the keeper B. As

keeper B is provided with a horizontal slot l1 defined by vertically spaced, horizontally disposed top and bottom walls 18 and I9, the top wall It being in the form of a ledge overhanging the bottom wall E9. The inner corners of the outer or front end portions of the top and bottom Walls are beveled ofi, as indicated at 2i-2il, to provide a flaring mouth portion or entrance opening to the slot. The structure just described forms the seat F with which the corresponding keeper A at the top of the door opening is also provided with an outstanding portion i6 presenting a seat F similar to the seat F hereinbeforev described, and having a slot defined by vertically spaced walls, the slot being indicated by H, and the walls by [8 and I9. This structure of the keeper A is the same as that of the lower keeper B but the arrangement thereof is reversed, that is, the outstanding portion [-6 is depending and the walls l8 and iii are respectively bottom and top. The cam slot E5 of the keeper A, which is engaged by the corresponding crank arm of the operating bar, differs from the slot [5 of the keeper B in that it opens downwardly instead of upwardly. The slot ll of the seat F of the keeper A is also provided with a flaring mouth defined by beveled edges 2El-2fl on the walls i8 and I9.

The bottom keeper B differs from the keeper A in that it is provided with a horizontally extending arm portion 2| on which a latch finger 22 is pivoted. The latch finger 22 is of well-known design and is engageable over the lower inner corner of the door [3 to latch the same in closed position, the corner of this door being provided with the usual protective wear plate 23, as shown.

The rotary operating bar C is preferably of rectangular transverse cross section and has end members 2424 secured to the top and bottom end portions thereof. Each end member has a keeper engaging crank member D formed at the outer extremity thereof. The bar C is rotatably supported by bearing brackets 25-25 secured to the door I2 adjacent the top and bot tom end portions of the latter. The end members 2 l24, the crank members D-D, and the supporting brackets 25-25 are all well-known in this art and therefore ,no further detailed description thereof is required, however, it might be pointed out that the end members are forked at their inner ends to embrace the corresponding end portions of the bar C to which they are riveted, and that the portions of the end men bers intermediate the forked portions and the crank member D thereof are of cylindrical shape and journaled in the bearing openings of the brackets 259-25.

Each crank member D comprises a horizontally disposed, radially extending crank arm 26 provided with a crank pin portion 27 at the outer end thereof engageable within the slot 55 of the corresponding keeper. end member 24 is provided with a radial lug E which is disposed in substantially horizontal alignment with the crank arm 28 but circumferentially spaced therefrom so as to form an obtuse angle with the same and so arranged that the lug E will be fully seated in the slot l? of the seat member F when the keeper engaging crank pin portion of the corresponding crank member D is seated in the slot I5 of the keeper in door locking position. The leading edge of each lug E is beveled off at the top and bottom, as indicated at 2L4 l, to facilitate entrance of the lug within the mouth of the slot ll of the seat of the corresponding keeper. The lugs EE snugly fit the slots 4 "IV-i7 of the keepers so that with the bar in looking position it is positively held against vertical displacement with respect to the keepers A and B and the wall of the car, thereby rigidly supporting the door against Weaving.

The bar C is operated by the usual hand lever G which may be locked against displacement by a latch 28 ordinarily employed for this purpose to maintain the door in fastened and closed position,

As is well known to those skilled in this art to open or close the .door the bar C is rotated by the handle lever G to earn the door cutwardly or inwardly through the action of the crank members D-D Within the slots i5|5 of the keepers. As the bar is rotated to open the door, the lugs EE are disengaged from the The crank end of each I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

I claim:
