Referring to the drawing in detail, the refer45 ence character 5 designates a portion of the frame

in notches 24 formed in the latch frame, as shown
by Figure 5 of the drawing. The intermediate 30
portions of the spring member, are coiled around
the pin 20, in Such a Way es 110 lend resiliency to
the spring member, and at the same time securely
mount the spring member within the latch frame.
From the foregoing it will be seen that due to 35
the construction shown and described, the keeper
plate, which is indicated by the reference char
actor 25, and which is carried by the closure, will
contact with the latch member II, when the clo
sure is moved to its closed position, moving the 40,
latch member into the latch frame, or to the po
sition as shown by Figure 6 of the drawing.
When it is desired to move the closure to its
open position, the closure is pulled in the usual
way. It follows that the keeper plate 25 moving 45
against the curved edge of the latch member ll,
will cause the latch member to move inwardly,
and assume a position as shown by Figure '7, re

moved to its open position.
