6 Claims.

This invention relates to improvements in door fasteners of the rotary bar type, and more particularly to locking means for holding the bar against rotation with the doors fastened in closed position.

One object of the invention is to provide simple and efficient means for locking the lever operated bar of a rotary door fastener against rotation in opening direction after the door has been forced to its closed position by rotation of the bar.

Another object of the invention is to provide a door fastener for hinged doors comprising a rotary operating bar mounted on one of the doors and having keeper engaging means thereon engageable with fixed keepers to force the door open and closed, wherein the bar is rotatable through 180 degrees in forcing the door into and out of the door opening and is actuated by a handle lever for rotating the same, the lever being pivoted to the bar in such a manner that it may be dropped to pendant position when the door is closed, the lever being provided with a locking projection which is engaged with a fixed plate on the door when the lever is dropped to pendant position, thereby preventing rotation of the bar in door opening direction and maintaining the door tightly closed.

A further object of the invention is to provide a mechanism as set forth in the preceding paragraph wherein the locking projection of the lever and the fixed plate have wedging engagement with each other as the handle lever is swung to pendant position, thereby forcibly turning the bar to its final locking position.

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

In the accompanying drawings forming a part of this specification, Figure 1 is an elevational view of the side wall of a railway car, provided with a door opening and having a pair of hinged doors for closing said opening, illustrating my improvements in connection therewith, the doors being shown in closed position and the operating handle .lever being shown in its pendant position in full lines and in the raised horizontal position in dotted lines. Figure 2 is a horizontal sectional view, corresponding substantially to the line 22 of Figure 1. Figure 3 is a broken view, similar to Figure l, on an enlarged scale, of portions of the doors at their meeting edges, the central portion of the operating bar, the operating lever for the bar, and cooperating locking plate. Figure 4 is a vertical s'ectionalview, corresponding substantially to the line 4- -4 of 13igure Figure 5 is a broken vertical sectional view, similar to Figure 4, with the operating bar and lever omitted, illustrating another embodiment of the invention.

In said drawings, l0 indicate the side wall member of a railway car, provided with a door opening H, closed by the usual hinged doors I2 and It. The doors I2 and 13 are supported along their outer edges by hinges |4-l4 of wellknown design. As will be understood by those skilled in this art, the hinged doors l2 and I3 are provided with beveled meeting edges, the edge of the door I2, which is the door last closed, overlapping the adjacent door I3.

The door l2 carries a rotary door fastener means of well-known design for forcing the door closed and also prying the same open, comprising a rotary operating bar [5 having keeper engaging crank members I 6l 6 at the top and bottom ends, cooperating with fixed keepers l1 l 7 0n the car wall above and below the door opening, the keepers being provided with the usual cam slots within which the crank members engage. The bar I5 is rotatably supported by top, bottom, and intermediate bearing brackets l8, l9, and 20, fixed to the door l2.

In carrying out my invention, as illustrated in Figures 1 to 4 inclusive, I provide broadly a combined actuating lever and locking member A, which is hinged or pivoted to the operating bar I 5 to be dropped to pendant position, and a looking or wedge plate B with which the locking portion of the lever A is engageable to lock the bar against rotation.

The combined lever and locking member A is of L-shaped form, having a barlike arm 2| provided with an outwardly offset hand grip portion 22 at its outer end, and a right angular portion at its inner end providing a locking finger or lug 23 extending laterally from said arm and projecting beyond the side of the bar [5 when the lever member A is dropped to its pendant position, as shown in Figures 1 and 3. The member A is supported on the bar l5 at the outer side thereof,

as seen in Figure 1, by a pivot pin 24 in the form of a rivet extending through the inner end portion of the lever member A and the bar l5, the pin 24 serving to hinge the lever member A for swinging movement in a vertical plane.

The locking or wedge plate B is in the form of a casting secured to the .outer side of the door l2 to one side of the bar I 5, the same being shown as disposed to the right of the bar, as seen in Figures 1 and 3, and in the path of movement of the finger or lug 23 of the combined lever and looking meme her A. The front surface or face of the plate B is upwardly inclined away from the plane of the door I2, thus presenting a fiat wedge face 25. At the upper end of the plate is an outstanding horizontal flange 26, which provides a limiting stoprengageable by the lug 23 for arresting the pivotal movement of the lever member A.

In the closed and locked position of the doors l2 and I3, as shown in Figures 1, 2, 3, and 4, the keeper engaging crank members |6l6 of the operating bar l are in locking engagement with the keepers l'i-ll, and the combined actuating lever and locking member A is in the pendant position shown in full lines iniFigure l, with the locking lug or finger 23 in wedging engagement with the plate 13. In the locked position of the parts, the bar I5 is effectively blocked "against rotation in door opening direction, that is, rotation in centraclo-ckwise direction, as viewed in Figure 2. is first swung upwardly to the horizontal dotted "line position shownin Figure 1, thus disengaging the lug 23 from the wedge plate 3. When the combined lever member A is swung to this horizontalposition, the right angular lug 23 is with- :drawn from its blocking position by being brought into alignment with the" length of the bar 15,

therebypermitting free rotation of the bar. The llevermember A is then swung from left to right through an-arc of 180 degrees to force the door partly "open in the usual well-known manner by 'camming action of the keeper engaging crank members l'6|i5 and cooperating keepers I'i-ll.

In forcing the door [2 closed, the operation is substantially the reverse .of that just described, the bar being rotated in clockwise direction, as 'viewed'in Figure 2, by swinging the levermemher A from right to left, thereby camming the door shut. The operating lever member is then swung to-its pendant position, bringing the lug '23 thereoiinto'wedging engagement with the wedge plate B. As will be evident, this wedging action-between the lever member A andthe plate .3 imparts a further slight turning movement to the bar in door closing direction, thus-forcing the keeper engaging crank members more firmly against the walls of the cam slots of the keepers and tightly locking the door.

Referring to the embodiment :of the invention illustrated in Figure -5, the construction is'the same as thatillustrated-in Figures 1 to 4 inclusive,

with the exception that the locking :c'am plate,

which is indicated by C and corresponds to the -.-plate B hereinbefore described, is provided with ;;23 of ;the lever ;member .A when the latter is dropped or swung .to its pendant position with the door l2;closed.
