3 Claims.
The present invention relates to new and use
ful improvements in latches particularly for cabi
net doors, gates, etc., and has for its primary
object to provide, in a manner as hereinafter set
5 forth, a device of this character which, while
positively securing a door, gate‘ or the like in
closed position, is adapted to be released with a
minimum of effort.
Other objects of the invention are to provide
10 a latch of the aforementioned character which
will be comparatively simple in construction,
strong, durable, highly efficient and reliable in
use, compact, and which may be manufactured
and installed at low cost.
All of the foregoing and still further objects
and advantages of the invention will become
apparent from a study of the following speci?
cation, taken in connection with the accompany
ing drawings wherein like characters of reference
designate corresponding parts throughout the
several views, and wherein:
Figure 1 is a view in side elevation of a latch
constructed in accordance with the present in
vention, showing same installed in a cabinet.
Figure 2 is a view in top plan thereof.
Figure 3 is a view principally in vertical longi
tudinal section, taken substantially on the line
3-3 of Fig. 2.
Figure 4 is a detail view in perspective of the
30 casing.
Figure 5 is a detail view in perspective of the
pivotally mounted ring yoke.
Figure 6 is a detail view in perspective of the
Figure '7 is a detail view in perspective of the
member which connects the ring yoke to the
operating rod.
Referring now to the drawings in detail, it
will be seen that the embodiment of the inven
40 tion which has been illustrated comprises a cas~
ing which is designated generally by the refer
enoe numeral I, said casing being substantially
rectangular in plan and including an integral
plate 2 having apertures 3 in its upper and lower
45 end portions which accommodate securing ele
ments for mounting the casing in position on a
cabinet door 4. The casing I may be of any
suitable metal and, as shown to advantage in Fig.
3 of the drawings, said casing is mounted on the
Ch 0
door 4 at a point above and adjacent one of the
shelves 5 of the cabinet 6. The casing I, it will
be noted, is open at its top and bottom and. the
plate 2 extends above and below said casing.
The upper portion of the plate 2 has formed
therein» an opening 1 the purpose of whichrwill
be presently set forth.
Extending between the side walls 8 of the
casing I, adjacent the plate 2, is a pin 9 on which
a yoke I0 is journaled for swinging movement in
a vertical plane. Projecting longitudinally from’
the upper portions of the ends of the yoke Ill
are lugs vII which are adapted to rest on the end
wall I2 of the casing I. Mounted transversely in
the lower portion of the yoke I0 is a pin>I3 on
which a gravity actuated ring I4 in the form of
a metallic tube is loosely mounted. The ring I4
is engageable behind a stop I5 which is adjust
ably secured on the shelf 5.
Mounted transversely in an upper portion of
the yoke I0 is a pin I6 on which an upstanding
plate I‘! is journaled. The plate Il has fonned
in its upper portion a threaded opening I8 (see
Fig. 7) . The door 4 has formed therein an open
ing I9 which is aligned with the opening ‘I in
the plate 2. The openings ‘I and I9 accommodate
a slidable rod 20 having a threaded inner end
portion extending through the opening I8 of the
plate M. It will thus be seen that the rod 20
is threadedly connected for adjustment to the 25
plate ll. A look nut 2| is provided for securing
the rod 20 in adjusted position. The rod 20 is
slidably mounted in a face plate 22 on the outer
side of the cabinet door 4. Fixed on the outer
end of the rod 20 is an operating knob 23. A
coil spring 24 encircles the rod 20 and has one
end engaged with the face plate 22
end engaged with the connecting
yieldingly resisting outward sliding
said rod. It will be observed that
and its other
plate I’! for
movement of
the openings 35
1 and I9 are of suf?cient diameter to accommo
date the coil spring 24.
It is thought that the operation of the latch
will be readily apparent from a consideration of
the foregoing. To release the door 4, it is only
necessary to exert sufficient outward pull on the
rod 20 to compress the coil spring 24, thus swing
ing the yoke I0 upwardly in the’ casing I until
the ring I4 will clear the stop I5 for permitting
said door to be swung open. When the outward 45
pull on the rod 20 is released said rod is re
turned to its former position by the coil spring
24 and the yoke I0 returns to its lower position
with the lugs II resting on the end wall I2 of
the casing I. When the door 4 is closed the 50
loosely mounted ring I4 engages and rides over
the stop I5 and drops by gravity to locking po
sition therebehind, as clearly shown in Figs. 1
and 3 of the drawings. When in this position
the ring I4 wedges between the stop I5 and the 55
end wall I! of the casing l thereby positively se
curingthe door 4 in closed position. When rid
ing over the stop I5 as the door is closed, the
ring l4 swings upwardly on the pin l3 into the
yoke It). It will thus be seen that little or no
effort will be required to close and latch the
door while su?icient effort to overcome the ten
sion of the spring 24 is all that is necessary to
release said door.
It is believed that the many advantages of a
latch constructed in accordance with the present
on the other end of the casing, a pin mounted
transversely in the yoke adjacent the open end
thereof, a gravity actuated ring loosely mounted
on the pin and engageable between the stop and
said other end of the casing for securing the
closure in closed position, and means for actu
ating the yoke for lifting the ring out of en
gagement with the stop, said means including an
upstanding plate journaled in the yoke, a hori
