DOOR-FASTENER FOR BOX-CAR SIDE DOORS.

Specification of Letters Patent.

Patented July 31, 1917.

A Application filed J' 1113' 26, 1916. Serial No. 111,420.

To all whom it may concern: ,7

Be t known that I, Wnm'ARo -B. Mrcns, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Door-Fasteners for Box-Car Side Doors; and I do hereby declare the following'to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use'the same.

This invention relates tonew and useful improvements in a door fastener for a box car side door and one of its objects is the provision of a device of this character, which shall be simple, durable and eflicient and which may be manufactured and sold at a comparatively low cost.

Another object of this invention is to provide a longitudinally extendin channel bar. secured to the car door and diaving a catch member pivoted thereto for an engagement with the doorway ost of the car to prevent the door from sli mg to an open position.

- A further object of this invention is to provide a casing secured to the channel bar .and having a pin therein, which is adapted I for movement in the casing to overlie the handle portion of the catch member and being sealed in this position to prevent the catch member from disengaging the post and freeing the door from a closed or locked position. e

A still further object of this invention is to provide a substantially L-shaped bracket securedv to the door jamb and received by one end of the channel bar to prevent the free end or edge of the door from being moved- 40 from. an engagement with the car when in a closed or locked position. I

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in cer- 45 tain novel features .of construetion, combination and arrangement of parts as will be hereinafter more fully described and cla'nned For a complete understanding of my invention, reference is to be had to the fol- 50 lowing description and accompanying drawing, in which Figure 1 is a front elevation of a door fastener for box car side doors, constructed in accordance with my invention,

Fig. 2 is a top plan view of the same,

-numeral 1 indicates a doorway post of a 'ment.

Fig. 3 is a sectional view taken on the line33 of Fig. 1,

Fig. 4 is a perspective view of the casing,

Fig. 5 is a vertical sectional view of the casing,.illustrating the bolt in an inoperative position, and

Fig. 6 is a similar view, illustrating the bolt in an operative position.

Referring in detail to the drawing, the

car, having a substantially L-shaped plate 2 secured thereon by a bolt 3. The L-shaped plate 2 has an opening therein in registra-l. tion with an opening in the doorway 0st 1 for receiving a catch member 4 carrie by a car door 5 of the sliding type, which will be hereinafter more fully described The numeral 6 designates the other doorway post of the car to which is secured a door strip 7 by means of bolts 8. The door strlp 7 is abutted by the door 5 when the door 5-is moved or slid to close the doorway between the posts 1 and 6, preventing the door from sliding beyond the post 6 and the post 1 when moved to a closed position.

A longitudinally extending channel bar 9 is secured to the door 5 by means of bolts 10. The rear wall of the channel bar 9 is slotted as illustrated at 11 which is in registration with a slot within the door 5. The. catch member 4 is of substantially L-shape and is pivotally secured to the side walls of thechannel bar 9 adjacent the slot 11 so that one arm portion of the catch member may extend through the slot 11 and the slot in the door 5 and has formed at right angles upon-said arm portion, a lag 12 which is adapted to move through the opening in the plate 2 and into the opening of the post 1 for locking the door 5 against sliding move- The other arm portion of the L-. shaped catch member 4 has a handle .13 formed thereon whereby the catch member may be swung upon its pivot to free the lug 12 from the post 1..

A casing 14 consisting of side walls 15, front wall 16 and a downwardly and out= wardly inclined rear wall 17. A pair of oppositely disposed feet 18 are'formed on the lower ends of the side walls 15 and are 105 apertured to receive bolts for securing the feet to one of the side walls of the channel bar 9 at a point as illustrated at 19. The upper end of the casing 14 is closed by a" top wall 20 which has a cut-away portion 21 110 and prevent the door 7 vthrough the casing .pm will be locked that extends downwardly within the front wall 16 as illustrated at 522 for receiving a locking pin-23. The pin has formed at right angles upon its upper end a head 24: which extends out of the casing through the cut-away portion 21 in the top wall for limiting the downward movement of the pin within the casing asclearly illustrated in Fig. 6. When desiring to lock the catch member 4 against movement, the pin 23 is moved downwardly within the casing through the openings 25 iii the channel bar 9 so as to overlie the handle 13 of the catch member and prevent same from being swung about its pivot to free the lug 12 from the post 1. In order to lock the pin 23 against movement, the side walls 1430f the casing have slots 26 for receiving a seal that is ssed through a slot 2'? in the pin, which. w ll prevent the pin from being raised upwardly to free the handle 13 of the catch member d.

Secured to the door step '7 is a substan tially l--shaped bracket 28 which has one of its arm portions projecting beyond the post 6 and in the direction of the post 1 to be received by one end of the channel bar 9 when the door 5 prevent the door from being moved from an on gement with the post (3 when in a closed ion,

rem the foregoing description taken in connection with the accompanying drawing, it will he noted that when the door 5 is slid to close the doorway of the car, it will abut the door step 7 and the channel bar 9 will receive the L-shapcd bracket :28 5 from being moved from an engagement swinging the catch member upon its pivot to move the lug 12 into engagement with the on ing of the post 1 the door will be pre- 1 from being slid to an open position.

vented By allowing the pin 3? within the casing 14 to slide through the openings in the channel bar 9, the catch member 4: will be locked against swinging movement, obviating the danger of the lug 12 from disengaging the opening in the post 1. By placing a seal 1e and the pin 23, the against movement with is slid to a closed position, to

with the post 6. v

the casing, thereby locking the catch memher which in turn locks the door 5 against sliding movement.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

A door fastener comprising a channel bar secured to a door: and having a slot therein, a catch pivoted between the walls of the channel bar and having one end disposed through the elongated slot and bentat right angles for engagement with the door frame,

a handle formed on the other end of said catch and adapted to be disposed between the-walls ofthe channel when the catch is in engagement with the door frame, a casing mounted upon one of the walls of the channel bar and having a slot in the top and front wall thereof, the walls of said channel bar having vertically arranged apertures in alinement with the slot in the top wall of the casing, a pin mounted within said casing and. adapted to be inserted through the apertures of the channel bar to overlie the handle of the catch, a collar formed on said'pin and adapted to engage one wall of the channel bar for limiting the movement of the pin throughthe apertures of the bar, a rightangled head formed upon the upper end of the bolt and adapted to be received within the slot in the top and front wall of the casing to lock the bolt against rotation when disposed through the apertures of the channel hat, and said bolt and side walls of the casing having alining apertures when the pin is disposed through the apertures of the channel bar to receive a seal.

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