ELMER LEWIS LEE AND EUGENE T. DE .WITT, OF DENVER, COLORADO.

CAR-DOSE.

Application filed January 6, 1914.

'1 b all whom, it may concern Be it known that we, llmncii Lnwis LEE and EUGENE T. Du TVI'IT, citizens of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Car-Doors, of which the following is a specification.

Our invention relates to an improvement in car doors, and the object is to provide a carrier for the door so that the door can be opened and closed at the will of the operator.

A further object is in the provision of means for causing the door to be locked snugly against the body of the car to prevent rain and sleet from entering the car when the door is closed.

A still further object is in the provision of a lever which is pivotally mounted upon the car, and is adapted to be thrown into engagement with the forward end of the door for releasing it, so that the door can be moved to an open position.

The invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in side elevation; Fig. 2 is a horizontal sectional view through the car, showing the lower rail; Fig. 3 is a horizontal sectional view through the car showing the upper rail in bottom plan; Fig. 4 is a cross sectional view through the car and upper rail; Fig. 5 is a detail cross sectional view through the lower rail and car door; Fig. 6 is a top plan view of the wedge located at the upper edge of the door; Fig. 7 is an end view thereof; Fig. 8 is a view in elevation of the wedge located at the lower edge of the car door; Fig. 9 is a cross sectional view thereof; Fig. 10 is a view in side elevation showing the manner of mounting the roller upon the upper rail; Fig. 11 is a sectional view through the rail and hanger; and Fig. 12 is adetail sectional view of the rear edge of the door.

A represents the body of the car, and B is the door. Mounted upon the car body are upper and lower rails, 1 and 2, respectively. Each rail is bent at its forward end as at 2, forming an oblique surface for engaging the forward outer edge of the door for causing the door to be forced tightly against the wall of the car.

The upper rail 1 has interposed therebe- Specification of Letters Patent.

tween and the car body a wooden strip 3, which is of greater width than the thickness of the car door, bolts 4, a passing through the rail, strip, and car body for fastening the rail and strip in position. The forward end of the strip extends downward within a distance of one-fourth of an inch from the top of the car door, so that if for any reason the door should tend to rise or move vertically, it will come in contact with the strip and prevent it from further vertical movement. Throughout the remaining length, there is a clearance of about one-half inch between the strip and upper edge of the oor.

Interposed between the car body and lower rail 2 are space blocks or fillers 5, 5, which support the rail and maintain it at the required distance from the car body.

Mounted at suitable intervals between the car body and rail 2 are rollers 6, 6, upon which the car door B is mounted, and upon which the door travels. These rollersare provided with annular flanges 7 a number of the flanges of the rollers being located adjacent to the rail, and the flanges of the rollers are in a position so that they will engage the outer surface of the door, and

will not interfere with the door coming in contact with the car body. The remaining number of rollers have the flanges located adjacent to the car body, so that the car door will be prevented from coming into too close contact with the car body, thereby injuring the car body. Without this provision, car doors are often allowed to come into such close contact with the side of the car body that it is difiicult to slide the door to aclosed position. The space blocks cause the rail to be held a sufficient distance from the car body, so that the rollers rotate freely.

Located on the bottom of the door is a metal strip 8, the ends of which are connected to the forward and rear edges of the door. This metal strip 8 rests upon the rollers 6, and forms a wearing surface for the door. 7 A wedge block 9 is mounted upon the door at the lower rear edge thereof, and is provided with a recess 10, having the periphery thereof arc-shaped, as at 11. The wall of the recess is somewhat ovalshaped.

Vhen the door is brought to a closed position, the forward upper and lower edges of the door will come into engagement with the oblique portions of the rails, l and 2, causing the forward edge of the door to be forced flange of the roller and the periphery of the recess of the block 9 will hold the door against rearward movement.

Connected to the rail 1 is a hanger 12, which is fastened thereto by means of rivets 13 and bolts 14, let, the bolts passing through the rail 1, wooden strip and the body of the car. A roller 15 is mounted upon the hanger, and is adapted to come into contact with the wedge block 16, connected to the. upper rear edge of the car door. '16 is provided with a lug 17 having a beveled surface 18. The roller, in coming in contact with the wedge block, does not engage the lug or projection 17 as there is generally a clearance of at least a quarter of an inch between the lower edge of the roller and the beveledsurface 18 of lug 17 but the engagement between the wedge block. and the roller forces the door against the side of the car for forming a snug and tight fit.

Should, however, the car door be raised by the engagement of the flange 7 of one of the rollers with the periphery of the recess 10 of the wedge block 9, the lug 17 will come in contact with'the roller and prevent the further movement of the car door.

The dooris provided at its upper forward and rear edges with U-shaped straps 20, which form a' wearing surface for the door.

The rear'edge of the door is preferably rounded as at 21, so that the rain and sleet and the like will be prevented from passing between the inner edge of the door and the side of the car. An angle iron bar 22is connected to the car door, and extends longitudinally thereof, and projects at right angles from the door a suflicient distance to cover the rollers and track beneath the door.

This block The forward edge or end of the door,when in a closed position, is wedged between the oblique surface 2, 2 of the rails 1 and 2 and the car body, and in many instances it would be impossible to release the door without bringing some pressure to bear against the forward end of the door. pivotally mounted upon the car body, and is adapted to engage a plate 26, on the for ward end of the car doorfor forcingthe door rearwardly or causing it to be disengaged from the oblique surface, and rollers, so that the door can be moved to an open position.

We claim: 7 j

1. The combination with a'car body having a doorway, of upper and lower rails con nected to the car body, above and below the doorway, flanged rollers interposed between the body and lower rail, a door mounted upon the rollers, wedge blocks on the door at the rear end thereof, one block located at the bottom of the door and the other at the top of the door, the flange of one of the rollers adapted to engage at the bottom of the door for forcing the door against the body of the car and holding the door against movement,

A lever 2% is and a roller on the upper rail engaging the other wedge block for forcing the upper portion of the door against the car body and holding it against movement.

The combination with a car bodyhav- 'ing a. door, of upper and lower rails conclosing the doorway, and the remaining rollers having the flanges located adjacent to the car body for causing the door to be held away from the side ofthe car when the door is in opened position.
