might be called a hasp 20 which is prefer-
ably of. L-shape with the outer end of its
long arm pivoted at 21 and the outer end of
its short arm provided with an eye 22, pins
3 23 and 24 or equivalent devices being placed
on the dog to limit the swing of this hasp.
The outer arm of the lever is provided with
a slot 25 which is so disosed that when the
door is fastened the short arm of the hasp
10 may be swung outward through this slot and
a seal wire passed. through the eye 22. This
obviously prevents the operation of the lever
to depress the fastening dog until the seal
wire is broken; and therefore the door can-
15 not be opened without the fact being dis-
covered. It is quite within the possibilities
of my invention that the door could be
positively locked in addition, and as illus-
trative of one means I have shown an ordi-
20 nary hasp engaging a staple on the strip S
and a padlock P through the staple. Iow-
ever, this detail has no bearing on the in-
vention.
An amplification is illustrated in Fig. 3
25 wherein the seal wire is not passed directly
through the eye 22 of the hasp. Here a hook
30 is pivoted at 31 on the lever so as to swing
alongside the outer arm thereof and its bill
may be dropped through the eye 22 in the
30 hasp. Said bill itself has an eye 32 through
which the seal wire may be passed. With
this detail employed, it is obvious that the
seal wire only prevents the disengagement of
the hook from the eye in the hasp, whereas
35 the bill of such hook positively prevents the
disengagement of the hasp from the slot in
the lever. With the construction shown in
Fig. 1 it might in some cases be possible if
the slot 25 were large enough to force the
40 tip of the hasp and the seal wire through
such slot which of course would not be de-
sirable. With the use of this amplification
it is quite possible to omit any positive lock
as at P.
45 Thus is produced a car door fastener
which acts automatically when the door is
moved to its closed position. It will doubt-
less be so moved by drawing on the handle
14 while the lever stands against the outer
50 face of the door, and when the latter reaches
the position shown in Fig. 1 and clears the
inner end 8 of the fastener, the pawl or dog
4 is thrown outward automatically by the
spring 7 as far as the pins and slots will per-
55 mit. If the hasp be employed, it will doubt-
less be projected automatically by this time
so that its outer end will pass through the
slot 25, and the seal can be applied in either
way described above.
6o What I claim is:
1. The combination with a sliding car
door, and a support on the car wall therefor ;
of a housing let into the wall in rear of the
door when closed, a dog mounted in said
65 housing and normally projected across therear edge of the door, and means movably
mounted on the door for depressing said
dog and then sliding the door.
2. The combination with a wall having a
door opening, a sliding door movable across
same, a door fastener, and means for nor-
mally projecting it across the rear edge of
the door when the latter is closed; of a lever
pivoted to the door at its rear edge with one
arm overlying said fastener, for the purpose 75
set forth.
3. The combination with a wall having a
door opening, a sliding door movable across
the same, a door fastener, and means for
normally projecting it across the rear edge 80
of the door when the latter is closed; of a
lever pivoted to the door at its rear edge
with one arm overlying said fastener, and
the other arm having a slot and a handle,
and means on the door engaging said slot 85
when the lever lies parallel with the door.
4. The combination with a freight car
wall having a door opening, a door slidably
mounted thereon, a stop at the inner edge
of the opening, a housing in the wall near 90
the rear edge of said opening, and a spring-
projected dog mounted in said housing and
adapted to stand across the rear edge of the
door when the latter is closed; of a lever
pivoted between its ends to the rear corner 95
of the door and having the extremity of
its outer arm enlarged and engaging the
outer edge of said dog and its inner arm pro-
vided with a slot, and a button on the door
adapted to pass through said slot and be 100
turned to hold the lever against the door.
5. In a device of the class described, the
combination with a sliding car door, a
spring-actuated dog normally projected into
the path of said door when closed, and a 105
lever on the door having an arm projecting
over the dog fo throwing the latter out of
the path of the door, said arm being slotted;
of a hasp pivoted at one end on the dog and
with its other end :adapted to be swung 1_o
through said slot, this end having an eye.
6. In a device of the class described, the
combination with a car door, a dog normally
projected into the path of said door when
closed, and a lever on the door having an 115
arm overlying the dog and slotted; of an L-
shaped hasp having one arm .pivoted on the
dog with the free end of its other arm in
position to project through said slot, such
end being pierced with an eye, pins on the 120
dog for limiting the swing of the hasp, and
a hook pivoted on the lever in position for
its bill to drop through said eye, said bill
itself being pierced with an eye, for the pur-
pose set forth. 125
7. The combination with a freight car
wall having a door opening, a door slidably
mounted thereon, a stop at the inner edge of
the opening, a housing in the wall near the
rear edge of said opening, upright pins in 1300
