Application led December 1.2, 1910. Serial No. 595,861.

To all whom t may concern.'

` of the village of Oak Park, county of Cook,

and State of Illinois, have invented certain new and useful Improvements in Car-Door Fasteners, of which I do declare the following to be a full, clear, and 'exact description, reference being had "to `the accompanying drawing, forming part of'this specification.

The present invention seeks to provide an improved fastencrfor the sliding doors of railway freight cars.` Ordinarily, a sliding door is suspended from a track arranged above and at one side of the door way, guides being provided for the lower edge of the door and which guides hold the door in vertical position and against the outer face of the door frame when the door is closed. In accordance with the present invention, improved fastening means are provided in connection with the guides for holding the door in closed position with the lower portion thereof within the door opening. lIhe invention consists in the features of improvement hereinafter set forth, illustrated in the preferred form in'the accompanying drawings and more particularly pointed out in the appended claims.

Figure l. is a View in side elevation showing a portion of the side of a car having my improved door fastener mechanism applied thereto. Fig. 2 is a view upon an enlarged scale on line 2--2 of Fig. l. Fig. 3 is a detail front View of the lower corner of the door and adjacent portion of the car wall. Fig. 4 is a view in vert-ical section on line 4l-fl of Fig. 3, but showing the locking bolt in the position indicated by dotted lines in Fio. 3.

'Ihe side wall A of the car is provided with a suitable door way or opening having posts B at opposite sides thereof. The posts B are provided with shoulders within the opening which are preferably tapered or inclined downwardly and inwardly so that the door can be held in closed position by the improved fastening' devices with the lower portion thereof within the door opening. 'Ihe sliding door D may be of any suitable construction. That shown comprises a frame al having' a sheet metal covering d. The sliding door is hung in front of the door in any suitable manner which will permit this lower edge being held wit-hin the cured, as usual tothe side of the car.

door opening when in closed position. In the construction shown, hangers E at the upper edge of the door are provided with rollers e which engage a Zfshaped track bar C that is fastened to the side of the car above the door opening and extends over the door l and into spaces c in the hangers.

When the door is opened and closed it moves in front of the door posts B, the movement being guided by L-shaped guide brackets K se- In accordance with the present invention, improved fastening means is provided in connection with the guide brackets K for holding the door in closed position with the lower portion thereof within the door opening and between the door posts B. In the preferred form shown, the fastening means comprises locking bolts H mounted upon the lower portion of the door.

For this purpose the lower portion ofthe door D is provided with attachedbrackets G that are conveniently fixed to'thedoor by bolts g and g. One of the bolts g serves as a pivot for a locking bolt Hp The upper end of each locking bolt H is formed with a slot i through which the pivot bolt g passes, so that the locking bolt H can not only swing on the pivot bolt g', but also can be raised bodily fora purpose to4 be'presently explained. Each of the locking bolts H, in the preferred form of the invention, is formed with an expanded lower portion it and with an outwardly extending part or tongue 72,2 that is adapted to lit within a seat 1^: formed in the upstanding portions 7c of the L-shaped guide brackets K K. To close the door, it will be moved laterally in front of the doorway until the edge of the doorfcontacts with the stop or plateF. As the door is thus moved, the lower edge ofthe door will travel inside the upstanding portions /o of the brackets K and as the locking bolts H strike these brackets they will be swung to one side, the locking bolt H at the left-hand end of the door D passing easily over the bracket K. When the door D is thus brought directly opposite the door opening7 the attendant will lift or slide upward the locking bolts H and at the same time will push or swing inward the lower portion of the door until the inner face of the door bears against the shoulders of the door posts B, and the locking bolts H will then be released so as .to cause their eXpaIldefl ill@ lowerfends it to pass inside the upstanding portions 7c of the brackets K K and to cause the tongues or projections h2 to rest within theseats la of the brackets.

It is manifest that when the door is thus brought to closed position, the locking bolts H, coperating with the brackets K, will se# ,upper portion will extend outside such opening.

When the door is to be opened, the attendant will lift the bolts H and swing them to one side of the brackets K K, so that the lower portion of the door will easily move outward to the vertical position indicated in Figa, when it may be slid to one side of the doorway.

It is manifest that the details of construction above set out may be varied within wide limits without departing` from the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is T n n l. In fasteners for railway car doors, the combination with a car having a door opening and posts on opposite sides of said opening and a sliding door therefor, o-f L-shaped guide brackets for the lower edge of the door, said guide brackets being liXed to the car and having upturned flanges arranged to overlap the outer face of the car door, andV locking devices arranged to fit between the upturned flanges of said brackets and the outer face of the door to hold the lower portion of the latter, in closed position, within the door opening and between said posts, substantially as described.

Copies'ofthis patent may be obtained for 2. In fasteners for railway car doors, the combination with a car having a door opening and posts on opposite sides of said opening and a sliding door therefor, of L-shaped guide brackets for the lower portion of the d0or,said brackets being fixed to the car and having upturned flanges arranged to overlap the outer face of the car door, and locking bolts mounted on the outer face of the door near its lower edge, said locking bolts having slotted upper ends, pivot bolts extending through said slotted upper ends for connecting said locking bolts to the door, and said locking bolts having enlarged lower ends arranged to lit between the upturned flanges ofsaid guide brackets and the outer face of the door to hold the lower portion of the door, in closed position, within the door opening and between said posts, substan# tially as described.
