FASTENER FOR CAR-DOORS.

Specification of Letters Latent.

Application filed December 20, 1905. Serial No. 292.599.

clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,A

forming part of this specification, in which- Figure l is a side elevational view of a portion of a box-car illustrating a door with iny improved fastening device arranged thereon. Fig. 2 isua detail view of the rear lower edge of the door, showing the fastening device in an operative position. Fig. 3 is a vertical sectional view on the line 3 3 of Fig. 2.

This invention relates to a new and useful improvement in fastening means for cardoors, the object being to construct the fastener in such manner that when the door is closed the fastener will drop into operative position with respect to its cooperating bracketkeeper and hold the door closed. In its closed position the fastener may receive the ordinary seal-wire.

In practice outside doors have. not been provided heretofore with any means, so far as I am aware, for holding them against movement, especially in switching` and sidetracking when the door is open. The result is that the door may work from its opened to its closed position, or vice versa, and render itself liable to injury. 1While it is not absolutely necessary that the door shall be closed when the car is empty, it is desirable for the reason that by keeping the door closed rain and snow are prevented from entering the car.

The ordinary fasteners on car-doors are of such character that the hasp and staple which lock the door in its closed position usually depend for the maintenance of their cooperative relation upon the seal-wire. In the absence of the seal-wire the door is free to be moved either to an open or closed position without restraint.

I provide a gravitating fastening device, preferably on the lower rear edge of the door, so that if the door be left open and in switching or transit when the door is closed said locking device will engage the keeper-bracket and hold the door closed against accidental displacement. On the other hand, should the door of an empty car be closed the presence of the seal-wire will not be necessary to hold the door in its closed position.

In the drawings, l indicates a car-door, which is provided with the usual roller-hanger at its upper edge, whereby the door issuspended from the track 2 extending along the side wall of the car.

3 arc the retaining-brackets, mounted on the side wall of the car and cooperating with the lower edge of the door. I prefer to provide these retaining-brackets with receding extensions on each side of the upwardly-extending retaining portion, so that in the event of contact with an obstruction the camfaccs will tend to ward oli such obstruction and save the bracket from being knocked from 'the side of the car.

4 indicates a yoke or stirrup-shaped member pivotallyvmounted at the lower rear edge of the door, the same being provided with an extension 5, having a depending locking projection 6 on its lower side. The inner face of this projection is preferably beveled, so as to ride up over the receding wall of the bracket. The bracket is provided with an opening 7 to receive the extension 6, which extension 6 is preferably provided with an opening through which a seal-wire may be passed, said seal-wire also passing through opening 7. The extension 5 is also provided with another opening 8, registering with an opening 9 in the bracket extension for convenience of passing a seal-wire through said opening. In this manner the pivoted fastening member may be sealed upon the bracket extension through either or both of the registering-openings, as desired.

In Iiig. 2 I have shown the parts in the position they occupy with relation to each other when the door is closed and sealed. To open the door, it is only necessary to break the seal-wire, raise the swinging member until the projection 6 is out of its opening 7, when the door can be opened. To close the door, it is only necessary to move it to its closed position, when the projection 6 will drop by gravity into its opening 7 and hold the door in such closed position, and when in such position the parts may be sealed if desired. j

I-Iaving thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

l. In a fastening for car-doors, the combination with a part provided with an open- IOO ing extending therethrough, of a pivotallymounted part having a projection designed to drop into said opening, said projection being provided With a longitudinally-extending opening to` receive the sealing-Wire which is also passed through the openingin the part irst referred to whereby said pivotallymounted member is fastened; substantially as described.

2. In a fastener for car-doors, the combination with a guide-bracket having horizontally-disposed receding extensions arranged on each side of an upwardly-extending retaining portion, one of said extensions being provided With an op ening, and a pivoted member mounted on the car-door and provided With a bevel-ended projection designed to cooperate With the opening in the receding extension of said bracket; substantially as described.

3. In a fastener for car-doors7 the combination of a guide-bracket having a sealingopening, and a yoke-shaped member pivotally mounted on the car-door and provided with a projection having an inclined face, which projection is designed to drop into a recess in the guide-bracl et, said projection being provided with a sealing-opening Which cooperates with the sealing-opening in the guide-bracket; substantially as described.

4L. In a fastener for car-doors, the combination of a bracket comprising an upwardlyextending retaining portion and receding extensions on each side of said retaining portion, and a movable member on the car-door for engaging a recess in one of said extensions; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of tWo Witnesses7 this 16th day of December, 1905.
