eral American Tank Car Corporation, Chicago,
lll., a corporation of VVes’í| Virginia,
Application July 16, 1936, Serial No. 90,969
5 Claims. (Cl. 292-266)
My invention relates generally to structures lengthwise entirely therethrough and in line with,
and opening into, the opening I8, the upper wall
presenting openings as for example, and more
particularly, in the case of hatches of refrig
erator cars, provided with closures mounted to be
5 moved into and out of closing position, and which
it is desired be locked either in closed position
or partially open position, as for instance to pro
vide for the ventilation of the space controlled by
the closure.
>10
My objects are to provide means for so lock
ing the closures; to provide means for locking the
closures in different partially open positions; and
to accomplish these purposes by a simple, inex
pensive, durable, and positively functioning con
15 struction.
Referring to the accompanying drawing:
Figure 1 is a fragmentary View, in sectional
elevation, of the hatch of a refrigerator car hav
ing a closure with means embodying my inven
20 tion for locking it in diiferent positions.
Figure 2 is a plan view of a retainer or casing
for a bolt forming a part of said means.
Figure 3 is a view in side elevation of the re
tainer or casing shown in Fig. 2, with the bolt
-25 in place therein.
the wall of the opening 20 as shown.
Movable lengthwise in the openings I1, I8 and
i9 is a bolt having a cylindrical portion 25 and
held against accidental separation from the cast
ing Ill which forms a bolt casing or retainer, by a 16
stop 26 shown as a rivet secured to the casing.
The bolt referred to has a handle portion 21
shown as extending from the body portion 25 at
a right angle thereto `and adapted to enter the
space 24 between the ribs 22 and 23 as shown 20
when the bolt is projected to the position shown
in Figs. 1 and 5 in which it extends ,at one end of
its cylindrical portion 25 into the openings I'I
and I8.

of the opening 2li being longitudinally slotted as
shown at 2l from a point adjacent the jaw I6
entirely through the opposite end of the tubular 5
portion I9.
A pair of spaced ribs 22 and 23 rise from the
body of the casting I4 between the ends of the
tubular portion I9 to provide .an upwardly open
ing recess 24 therebetween which extends through 10
Figure 6, an enlarged fragmentary sectional
view taken at the line 6 on Fig. 3 and viewed in
the direction of the arrow.
Referring to the construction shown wherein I
have illustrated my invention as provided for the
35 locking of a hatch cover, of a refrigerator car,
in different positions, a portion of the roof of the
car is shown at 'I andthe hatch thereof which
opens into the ice compartment and as common
ly provided, at S. The cover for the hatch 8 is
40 shown at 9 and is provided with the usual depend
ing plug portion Ill which ñts the hatch 8 in sealed
engagement therewith when the cover is closed,
the cover being hinged along one edge as repre
sented at Il to a bracket I2 secured to the roof
45 of the car adjacent the hatch thereby adapting
the cover to be swung from closed position repre
sented by the dotted lines at the right-hand side
of Fig. 1 to the full open position shown by the
dotted lines at the left-hand side of Fig. 1.
50
Secured to the top surface of the free edge por
tion of the cover 9, as by bolts I3, is a casting I4
formed with spaced apart jaws l5 and i6 having
alining openings I1 and I8.
The casting It is also formed with a tubular
55 portion I9 having an opening 26 extending
jaws I5 and IG for engagement by the bolt above 30
described which may enter the one of the holes
3l) in registration therewith.
The lowerrnost one of the holes 30, preferably
slightly elongated, is so positioned that it registers
with the bolt when the cover is swung to lower- 35
most horizontal closed position as shown by the
dotted lines at the right-hand side of Fig. 1, thus
permitting of the locking of the cover in closed
position. The others of these holes are provided
to permit the cover to be locked by the bolt in va- 40 ‘
rious degrees, as desired, of partially open posi
tion, as for example as shown by the full lines in
Fig. 1 wherein the bolt extends into the upper
most one of the holes 3B for locking the cover
in the extreme partially open position.
45
When the cover has been locked in the desired
position stated, locking means may be sealed
against release as by means of a so-called car seal
such as the common form of strap car seal shown
at 3l the strap portion of which is threaded 50
through vholes 32 in the ribs 22 and 23 and a reg
istering hole 33 in the handle portion 21 of the
bolt. Other sealing means for the lock may be
used as for example a seal pin 25a inserted into
an opening in the protruding end of the bolt.

In assembling the bolt and casing the bolt is
introduced at the end thereof farthest from the
handle 21 into the outer end of the opening 20
and slid along the member I9 to a position in
which the other end of the bolt clears the enter
portion for projection through said opening to
engage the lock lever, said latter jaw thus func
tioning dually in the guidance of both the lever
that the bolt may be withdrawn from the space
between the jaws I5 and i6 to permit of the
and the securing bolt, operating means on the
bolt extending through said slot, and means ex
manipulation of the lever 29.
While I have illustrated and described a par
tending into' the bore of the tubular portion to 10
it thereto, »as the same may be variously modified
and altered without departing from the spirit of
my invention.
What I claim as new, and desire to secure by
Letters Patent, is:
,
1. A device adapted to be mounted on a clo
sure in cooperation with a lock lever, the device
comprising an'attaching plate, spaced jaws on
the plate open at one end to receive the lock
lever, a tubular portion on said plate having one
end open through one of said jaws, and a movable
securing bolt for said lock lever mounted by said
tubular portion adapted for projection through
sai-d opening, the last mentioned jaw thus func
tioning dually in the guidance of both the lever
and the securing bolt.
40
at the end of the tubular portion remote to the
jaws, a securing bolt slidable in said tubular
ing end of the opening 20 and the stop 26 then
applied to` position, the latter being so positioned

do not wish to be understood as intending to limit
