force of the spring is exerted to move said jaws
The keeper is permanently secured to the door
toward each other with the exertion of a camming
jamb or frame 1. It is made from sheet metal,
action on the jaws which causes the door to be
having a flat foot-piece 8 preferably screw con
nected to the outer side of the door casing 1 and 55 held tightly closed. Any force which may act on
the door tending 'to open it with the jaws of the
latch engaged with keeper head Il is ineffective
to move the door, as there is no component of
such force which can be resolved in a direction
to turn the jaw members away from each other
about the pivot pin I8.
For manual release of the latch from the keep
er an operating handle member is provided, com
prising a plate 2| of sheet metal which at one of
its edges is extended to provide two spaced apart
angles having legs 22 and 23 at right angles to
each other, said legs 22 being in substantially the
same plane as the plate 2l and from the inner
edges of each of which a tongue 24 extends as
shown. Initially the tongues 24 are turned to .
parallel the legs 23. With such initial shape the
angle members 22-23 and the tongues 24 may
be passed through channel slots 25 cut in the
back 2 of the housing or casing immediately with
in the top 3 (Figs. 1 and 3). After this has been
done the tongues 24 are bent toward the top 3 of
the housing, as shown, thereby locking the op
erating member against disengagement, but per
mitting a limited pivotal movement in the slots
25. Said angle extensions 22-23 lie over the
tail-pieces l1. With the latch engaged with the
keeper, as in Fig. 1, an engagement against the
inner side and at the outer end of the plate 2|
will move the legs 23 into contact with said tail
_posite sides thereof, spring means acting on said
jaw members to normally move the jaws toward
each other, each of said jaw members at the end
thereof opposite where the jaws are located hav
ing a laterally extended tail-piece, and manually
operable means extending through a side of the
housing and pivotally mounted'thereon for en
gaging said tail-pieces on operation of said means
to swing said jaw members to move the jaws away
from each other.
2. A latch construction comprising, a housing
adapted to be secured to a door and having an
opening at a, side adapted to be presented to a
door jamb when the door is in engagement there
with and receive a keeper connected to said door
jamb, said keeper extending into the housing
through said opening, two jaw members, each of
said jaw members comprising a side, a jaw turned
substantially at right angles from one end of said
side of each jaw member, a flange turned in the
same direction from the other end of said side of
each jaw member and an ear bent from said
flange parallel t0 the side of its respective jaw
member, said jaw members being located one with
the side thereof against the inner side of a side of
said housing and the other against the inner side
of the opposite side of said housing, a pivot pin
passing through said sides and ears of the jaw
members and carried by opposite sides of the
pieces I1 and turn them about the pivot pin I8 30 housing, each of said jaw members having a tail
to separate the jaws l5 from each other a dis
piece extending outwardly from said ñange por

the keeper. The door is thereupon opened. Upon
