UNITED STATES ROY E. oAa'rzDArNER, or oOLUMBUs, OHIO, ASSIGNOR TO THE KILBOURNE AN'D JACOBS MANUFACTURING COMPANY, or COLUMBUS, 01110.5 CORPORATION; OF

OHIO.

DUMP-CAR.

To all whom it may concern Be it known that I, ROY E. CARTZDAFNER,

a citizen of the United States, residingat Columbus, in the county of Franklin and State of Ohio, have invented certaln new and useful Improvements inDump-Cars, of which the followin is a specification.

My invention relates to improvements in dump cars, and includes strong and simple means for operating to open and closed posi- .tion the swinging door of a side dumping car, and for preventing the overthrow of the door when it is being opened to permit the discharge of the lading. Essentially, I provide a reinforced hinge like member carried rigidly on the door wherethrough the .door is pivotally. suspended from the horizontal bar hereinafter described, and a positive connection between the hinge and the vertical bar supporting the said horizontal bar causes the door to be swung open or drawn to a closed position, the door carrying a stop member adapted to engage the said horizontal bar appropriately and prevent over throw of the door 'when the latter is swung open.

In the accompanying drawings which are hereto annexed and hereby 'made a part of this specification, Figure 1 is an end View of a car having my improvement; Fig. 2 is an end View of the car in dumped position; Fig. 3 is an enlarged detail of the hinge like member and its operating connections, also showing the stop member; Fig. 4 is a view of the plate carrying the stop member detached from the door; Fig. 5 is a section along the line 11 in Fig. 4; Fig. 6 is a View of the hinge likemember from the side and front thereof.

Referring to the drawings in which the same numeral indicates the same feature throughout, 1.is the bed or body of a ear the door 4 is automatically moved to open position, as is usual in this type of cars. Said parts are here shown in duplicate and will therefore be described for only one side of the car; they include the horizontal door carrying bar 4 pivoted at 5 to the end of the car, and supporting the door in suspendedpositionfrom the pivotal connection 6 with the hinge like member 7; the latter is se- Specification of Letters Patent.

cured to the end of the door through the I rivets or bolts 8 which connect it with the parts now' to be described. on the-outer side of the end of the car door is mounted the angle 9; secured to this angle and to the end of the door at 10 is the plate 11 whichforms a facing for the end of the door; at its upper edge said plate 11 is turned to form the stop 12 which overlies ;the'upper edge of the bar 4 in inclined position, and when ,the

door is swung to open position as shown, in

has the rearward extension 13 which is appropriately bent and formed to receive the bar 4:, and the pivot pin 6 is inserted through said extension 13, the bar 1, the plate 11, and

the angle 9, thereby forming a. strong, se-

cure and simple hinge like construction. Secured pivotally to the upper edge of said extension 13 at 14, is the arm 15, which at its other end is pivotally associated with the vertical bar 16; the latter is pivotally connected at one of its ends with the bar 4, and at its other end with the bar or arm 17, the latter being pivotally mounted on the under frame of the car at 18.

When the car bed is dumped toward the right as appears in Fig. 2, the end 19 of the arm 17 is carried downwardly until it comes into contact with the stop 20 on the underframe, whereupon the vertical bar 16 arrests the further downward movement of the bar 4 which holds the door aloft while the car bed continues to be tilted to that side, the bar 4 acting as a lever, the end 5 of which is pulled downwardlyby the car bed, thereby elevating the door carrying end. The arm 15 now exercises a positive retracting influence on the -door through the connection 14 with the extension 13 of the hinge like construction, whereby the door is swung on the pivot pin 6 in such a manner as to. enlarge the mouth being formed on that side of. the car for the discharge of the lacling., If the descent of the car bed has been rapid or the lading is loose and has been -tossed against the door, the latter is given a sharp swinging movement which may be sufficient to overthrow the door; to prevent such results the stop 12 is brought into engagement with the upper edge of the bar 4 as appears in Figs-2, 3 and 6.

When the car bed is being restored to its normal horizontal position, the arm 15 positively retracts the door to closed posithe intervention of a catch or stop such-as is frequently used in cars of this type. My improvements therefore, accomplish positively the opening of the door, prevent its overthrow, positively return the door to its closed position, and hold it securely closed against the outward pressure of the ladin'g in the car without the cooperation of a catch of any sort, it being clear that the effect of the arm 15 on the door through the hinge like member 7 when the door is closed, is to lift the extension and thereby to tend to swing the. lower end of the door inwardly and to hold the door up close against the ends of the car.

hat I claim is I 1. In a dump car having a pivoted bar mounted at one end thereof, and a vertical supporting arm pivotally secured thereto, a door pivotally suspended from said bar. a rigid hinge like member secured to the end of the door and formed to receive the end of said bar and to cooperate in providing the pivotal conne tion between said'bar and door, and having a rearwardly extending portion, and an arm pivotally associated with said extending portion and said vertical arm whereby said door is positively swung to open position and retracted to closed position and securely maintained therein.

2. In a dump car having a side door, a horizontal bar mounted on the end of said car from which said door is pivotally suspended, a vertical supporting bar pivotally associated with said horizontal bar, a reinforcing hinge like member mounted on the end of said door, a connecting arm pivotally associated at its ends with said vertical bar and said reinforcing member whereby-said door is swung to open position positively as the car bed is dumped, and said door is swung to closed position positively as said car bed is righted and main I tained therein.

3. In a dump car having a side door, a horizontal bar mounted on the end of said car from which said door is pivotally suspended. means for causing said door to swing open as said car bed is dumped, and means carried by said door adapted to engage said bar to prevent the overthrow of said door in its opening movement.

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