DOOR

Filed Dec. 18, 1928 2 Sheets-Sheet 2 Patented July 26, 1932 UNITED STATES :PATENT OFFICE V GEORGE A. SPILLER AND GEORGE T JOHNSON, OF COLUMBUS, OHIO, ASSIGNORS TOTHE BUCKEYE STEEL GASTINGS COMPANY, OF COLUMBUS, OHIO noon I Application filed December 1a, 1925. Serial No. 326,823.

The present invention pertains to doors, and especially to drop end doors for open end freight cars of the gondola type.

It is customary to make such doors of builtup construction, and it is known to those conversant with such matters, that such doors have some very weak points. The type of car with which such doors are employed, is becoming more widely used, and is almostinvariably of the lar est capacity; namely, 7 tons, and they are loaded with all kinds of heavy bulk material, including pipes and other, rolling mill products, and all such lading has a tendency toshift when the cars are bumped around in service; and the shifting of the load throws considerable strain upon the end doors, which in View of the fact that they are separate movable pieces, are not of a construction best suited for resisting such forces. As a result, the end doors bend or bulge outwardly at the top, indicat- 7 ing that the pressed steel doors of the conventional design are notas rigid as would seem to be necessary. The bottom of'the door, being toed against a door abutment'that is secured to the end sillof the car, is kept in alignment for a while, but assaid abutment is formed of a relatively light sheet metal upturned lip, extending the full width of the car, and is not very strong; due to corrosion and rough usage, the vertical lip of the abutment becomes bent, and allows the door to also bulge outwardly at the bottom.

with additional objects which will appear as the description proceeds, the invention consists in the novel features hereinafter describedin detail, illustrated in the accomend, as shown at 6;

length of the door,

panying drawings, and specifically pointed out in the annexed claims.

.Referringto the drawings,

Fig. 9 is an enlarged elevation of a detail of the door shown in 8.

Fig. '10 is a vertical sectional view 1010 of Fig. 8.

The improved door is of unitary construcon line 'tion, and formed of one piece of metal, preferably cast, and shaped to provide the requisite stability.

1 designates the main web or wall, bordered by anangular flange 2, which provides a channel shaped reinforcement at each edge of the door. Asbest shown in'Fig. 1,

this flange, at the upper end of the door, extends downwardly in the form of a depending skirt 3, which is of greatest depth atits middle 4, and is gradually tapered from this point toward the ends of the door. The flange makes the edge portion of the door extremely rigid, and the deepening of the part 3 provides increased reinforcement at the top of the door, which must resist the greater strain.

Vertical ribs 5 are provi'ded on the inner faceof thedoor, and each of these ribs mergesinto themain web 1', the flange 2, and theapron 3, and each. rib is gradually tapered toward themain web near its. lower A main horizontal rib 7 extends the full and its ends merge into the side flanges at the points 8.

These intersecting vertical and horizontal ribs are also provided with integral reinforcing flanges 9, which merge into the inner extensions of the flanges 2, and the flanges on each vertical rib 5 are integrally united with the main web, as shown at 10.

The lower central portion of the door is reinforced by a shorter horizontal rib 11, having tapered end ortions terminating short of the ribs 5, an the rib .11 is also reinforced by oppositely extending flanges 12 that merge into the web 1. The ribs and their reinforcing flanges may be looked upon as T-shaped reinforcements.

As doors of this type are used in close proximity to the brake wheels at the ends of the car, the metal of the web is shaped as shown at 18, to provide a pocket into which the brake wheel may project and allow clearance for the hands of the operator.

Apertured ears 14 are arranged in pairs near the lower side of the door to form parts of the hinges employed in pivotally connecting the lower side of the door to the floor of thecar.

By way of reiteration, it may be noted that thetop edge of the door has a channel construction for increased strength, and the three of its sides. Due to this, the main horizontal rib 7 may be located nearest the top edge of the door. This main rib and the nearby channel at the top edge, will eliminate bending at and near the top of the door.

As the door forming the subject matter of this invention was designed especially for use with a car end of the type shown in application Serial No. 322,284, filed November 27, .1928, it need not be as rigid at its lower end as. at its upper end, for a heavily reinforced abutment of the cast steel car end will prevent bulging along the bottom edge.

The castingmay be made with holes 15 at each end near the upper corner of the door to receive the rivets employed in connecting the latch links to the door, or as shown in Figs. 8, 9 and 10, the door may be provided at these points with latch hooks 16 which are integral portions of the casting that forms the door. Each hook is formed by an upwardly extending arm 17 reinforced tion at the end of the car.

It is believed from the above description that the construction and advantages of the invention may be readily understood, and it is manifest that changes may be made in the structure disclosed without departing from the spirit of the invention as expressed in the claims.

What we claim and desire to secure by Letters Patent is:
