Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed April 18, 1914. Seria1No.832,990,'

To all whom it may concern:

Be it known that I, RICHARD WVEBB BUR-v NETT, a citizen of the United States of America, and resident of the city of Montreal, in the Province of Quebec, and D0- minion of Canada, have invented new and useful Improvements in Car-Door Fasteners, of which the following is a full, clear, and exact description.

This invention relates to improvements in fastening means for box cars, and the object is to provide a simple, durable and ,inexpensive means for locking and sealing a door-which cannot be tampered with or opened in any way without breaking the seal, and in which the seal is relieved from all stresses of thBlOCklIlg device.

In the drawings which illustrate the in vention:Figure'1 is a front elevation of the door. Fig. 2 is a sectional view on'the line 22, Fig. 1. Fig. 3 is an enlarged front elevation of the locking means. Fig. 4 is a sectional View taken through the lock on Fig. 1. v

Referring more particularly to the drawings, 11 designates the end of a car which in the drawings is shown as of the outside 7 metal frame type, the frame members being thicker than the door.

designated 12 and the sheathing 13. An opening 14 is provided through the sheathing between the frame members 12 and is adapted to be closed by a door 15 preferably formed of a single sheet of metal.

Strips are attached to adjacent flanges of the frame members or to the sheathing to space the door away from the sheathing and I prevent friction, and also so form slides for the door. Upon these strips, further filling strips 17 are mounted, which are slightly Above these again Y are mounted guide strips 18 which hold the door in place. It will be readily seen from Fig. 2 that the strips 16, 17 and 18 form together grooved guides in which the door is securely held against removal, but permitted a sliding movement. At the upper and lower edges'of the door opening, strips 19 are attachedto the car'sheathing corresponding in thickness to the strips 16 and forming upper and lower j ambs for the door.

The locking means consists of a flanged base plate 30 secured to some stationary portion of the car, as for example, to. one of the guides immediately above the door opening.

This flanged base plate is preferably a short piece ofangle iron provided with an aperture in flange thereof. The locking pin passes through the guides and into the car sheathing, which is above the top of the door when the same is closed and is an easy at 10 for the reception of the seal wire, and in its head at 41 for the reception of an attachingchain. The head of the sealing pin 39 is provided with a flanged wing 42 which engages the head of the locking pin in such a manner as to insure the assembly of the two pins with the seal wire holes in register. The locking pin is in turn secured in place by the sealing pin, the two pins being sealed together and the sealing-pin held against revolution so that the seal wire Would be broken by twisting of the pin.

Having thus described my invention, what I claim is i 1. In a car, a slidable end door, means for locking the door in open or closed position comprising an apertured flanged base plate fixed adjacent the door opening, a socket, a pin insertible in said socket in the .path of the door, a U-shaped apertured head on the pin embracing the flanged base plate, a wing on said head, and locking means securable to said head wing insertible through the apertures of the pin'head and flanged base plate.

2. In a car, the combination with a slidable end door and its guides, of means arranged to lock the door in open or closed position comprising an apertured flanged base plate secured to the door guides, a socket, a pin ,insertible in said socket in the path of the plate. This pin 39 is apertured in its point I able end doorand its guides, of means arsocket, a pin insertible in said socket in the path of the d00r,'an apertured head on said pin embracing the flanged base'pla'te,

an apertured Wing on said locking pin head;

an apertur'ed sealing pin insertible through the locking pinhead and flanged base plate,

and a flanged wingprojecting from the head of the sealing pin embfacing the head oi the T locking pin and aiming the apertures ofthe sealing pin and locking pin Wing tohold the sealing pin against] movement tending to break a seal Wire lnserted therethrough.

In wltness whereof, I have hereunto set 1 my hand, in-the presence of two Witnesses;
