WILLIAM BURR GREGG, OEHACKENSACK, NEW JERSEY, A-SSIGNOR TO THE, GREGG To allwhom it may concern) iBe'it known that I,WILLIAM BURR GREGG,

' ajcitizen of the United States, residing at companyin'g drawings, and to the letters and figuresofreference marked thereon, which form 'a part of this specification.

invention relates to railway cars, more particularly to cars for "transportation of cane, and has for its object to provide a hinged door *which will have 'annoutward andj a lateral-movement'to release it from its fastenings,'andmeans'for securing the door in its closed position, as hereinafter particularly described and then sought'to be clearly defined by the claims, referencebeing ha'dto. the accompanying drawing forming a-part hereof and in which Figure lis a side viewof a portion of a carof any approved construction and having the invention applied thereto;

Fig. 2 a sectional view on the line 22 of Fig. 1, looking in the'direct'ion of'the arrow,'with parts broken away; i

Fig. 3 is a detail perspective showing the additional-safety catch, parts broken away, and a section of the adjacent end stakeoi' the door; .11- '1' Fig. 1 a detail view:of one'of the stakes of the door with its hinging eye in section and indicating the outward-swinging and lateral movement of the door. I

In the drawing the numeral 1 indicates a portion of a car frame of any approved type of construction; 2 two of the wheels; 4: one of the side-sills; and 5 one of the top beams of the frame.

The door is indicated by the numeral 6 and may be solid or of open construction, and preferably is formed of any desired number of upright stakes 7 of channel or L iron formation and

end stakes

8 and 9 which likewise may be of channel or L iron formation. "For convenience the intermediate stakes 7 may be shorter than the end stakes and at their lower ends be connected to one another and to the end stakes by an L bar 10.

Specification of Letters Patent.

COMPANY LIMITED, HACKENSACK, NEW JERSEY, A CORPORATION OF NEW "sInE-nUMr-pooR LATCH FOR CAR- AND OTHER noons.

Patented Jan. 21, 1919.

' Application filed August 6, 1915. serial No. 44,116.

At their upper ends the several stakes are provided'with eye straps 11 through each of which passes a suspension rod or bolt 12, preferably one for each stake-eye and ears 13 which secure them to the upper beam 5 of the car-frame. A loose connection between the eye-straps and suspension rod or bolt is provided so that the door may be swung outwardly and also have a lateral play or movement 1n the disengagement of the door from its fastening means as hereinafter indicated.

The door is held in its closed position by means of a suitable clip 14, which may be 2 shaped and bolted or riveted to the side-sill of the car so as to embrace the lower part of the end stake'8 when the door is closed,'and by a stake-pocket 15 or other holder of any suitable construction bolted to the side-sill so asto receive the other end stake 9 when the door is closed. The form and construction of stake-pocket preferred tobe used is that illustrated which has a latch 16 adapted to have an oscillating movement on its pintle so that-the latch may be lifted to release its free end from its keeper and then swing on'its pintle so as to open passage of the end stake. I do not however lim t myself to the use of this particular form of stake-pocket or holder;

As an additional safety-catch, and which may be used with the stake-pocket or holder omitted but is preferably used in connection therewith, I provide a latch-lever 17 fulcrumed to the side-sill of the car by a pivotpm 18 and having a bent-end 19, which will lap over a lip 20 bolted or riveted to the end stake of the door soas to prevent outward swing of the door and also lateral movement thereof as the end of the lip may abut against the shoulder of the latch formed at the point of deflection of the bent end of the latch-lever. Thus the door Iwill be held in its closed position if from any cause the latch of the stake-pocket should become accidentally displaced. A stop 21 may be secured to the side-sill to hold the latch-lever 1n posltion, but any other suitable means may be used for holding such latch-lever.

In operation, to permit the door to open the latch of the stake-pocket is thrown open, and the latch-lever 17 is disengaged from en- -,oagement with the lip of the adjacent end stake, whereupon the pressure of the cane against the door will press the end-stake 9 out of the pocket, a portion of the door for the pocket for the some distance back from the end stake being swung outwardly with the end-stake 9, and when the end-stake passes outside the pocket the continued pressure of the cane against the inside of the door swings'the door farther outward and at the same time causes the door to swing or move laterally away from the clip or keeper 14: so as to withdraw the end-stake 8 out of the keeper 14, as indicated in dotted lines Fig. 1 and then the door is free to swing outwardly throughout its entire width so that the cane may be discharged from the car.

In closing and fastening the door, the door is swung laterally on its suspension supports to bring the end stake 8 within the keepefltand then inwardly to bring the end-stake 9 within the stake-pocket 15, and then the latch of the pocket is engaged in its keeper and the safety latch-lever turned to bring its bent end into engagement with the lip 20 of the end-stake 9, and the door is thus securely fastened in its closed position.

It will be apparent from the foregoing that in order to open the door to permit the discharge of cane from the car, the door must swing or move laterally and also outwardly to be released from its fastenings. This affords a greater degree of security and reduces the liability of accidental disengaging of' the fastening means.

I have illustrated and described the preferred details of construction and arrangement of the several parts but it is to be understood that changes can be made therein and essential features of the invention retained. It is also to be understood that while the invention is particularly well adapted for use on cane-cars it serves the same useful function of its operative part-s when and where otherwise applied and used.

It is to be further understood that the door can be manipulated and opened whether the car is loaded or empty. Also that the lateral motion may be a sliding movement by the suspending eye straps moving lengthwise of the suspension rod or bolt.

Copies of this patent may be obtained for Having described my invention and set forth its merits, what I claim is:

1. A door hinged along its upper edge to move in two directions at angles to each other, and separate fastening means disposed in respect to different parts of the door, one of which permits the door to move in one direction and the other when released permit it to swing in another direction.

2. A door hinged along its upper-edge to move in two directions at angles to each other, and separate fastening means disposed in respect to different parts of the door, one of which when released permits the adjacent part of the door to swing outwardly and the other permits the door to move in a lateral direction.

3. A door hinged along its upper edge to move in two directions at angles to each other, and separate fastening means for securing the door, one means comprising a stake-pocket or holder which when opene permits the door to swing in one direction, and the other means being substantially a pocket with an open side to permit the door to move laterally when to be opened and normally preventingv outward swing of the door.

4. A. door hinged along its upper edge to move in two directions at angles to each other, and separate fastening means for securing the door, one means comprising substantially a pocket with an open face to permit the door to swing laterally when to be opened and normally preventing outward swing of the door, and the other means comprising a pivoted latch-lever disposed to engage a part of the door to normally prevent outward swing of the door and when released permitting lateral and outward swing of the door.

In testimony whereof I affix my signature in presence of two Witnesses.
