This invention relates to a combination lock
and latch structure.
The chief object of this invention is to pro
member I'I. This post is slotted as at I8 to nest
the lock body.
Referring to Fig. 6, it will be observed that
vide in a single structure a latch which can be
locked and which can have associated therewith
this member I‘I retains the cushion bumper struc
ture I9, and this is adapted to seat in the groove
I2a in cushioning post to post contact when the
other locking elements for providing additional
locks.
The chief feature of the invention consists in
closure is closed.
providing a latching member that is manually
movable from a retracted to a projected position,
prised of a pair of plates 26 suitably secured in
spaced relation by means of spacing members 2l
and suitable connectors 22. Also interposed in
thehousing is a pair of spaced aligned guides
23 which are in vertical alignment and a pair
of guides and stops 24 and 25 which also happen
to be vertically aligned and are adjacent the
opening I5. A bearing member 25 includes a
stem 2l slidable in guide 23. Confronting the
lsame and above it is the bearing member 28
having upwardly directed stem 29 slidable in the
upper guide 23. C-shaped springs 3B are suitably
and when projected, the same is arranged to
function as a catch and which furthermore is
provided with means for maintaining the catch
in the locked position.
Other objects and features of the invention
will be set forth more fully hereinafter.
'
t The full nature of the invention will be under
stood from the accompanying drawings and the
following description and claims:
In the drawings Fig. 1 is a vertical sectional

vided with a catch plate arrangement, a closure
that is slidable to and from that wall and a lock
structure carried by the latter.
.
interposed between the spacing members 2i,
which serve as spring anchors, and the members
y 26 and 26 and will normally constrain these mem
bers towards each other.
Interposed between these members is a cross
head element SI which is apertured as at 32, and
herein said aperture is shown square and serves
Fig. 2 is a transverse sectional View taken o
line 2-2 of Fig. 1 and in the direction of the
arrows.
Fig. 3 is a vertical sectional view taken on line
3_3 of Fig. 1 and in the direction of the arrows.
Fig. 4 is an elevational View taken in the plane
4--4 of Fig. 1 and in the direction of the arrows.
Fig. 5 is a view similar to Fig. 1 and is a mod
ified form of the invention.
Fig. 6 is a sectional View taken in a plane par
allel to the plane 2_2 and remote from the lock.
In the drawings I0 indicates a channel having
the base portion Iûa which is slotted or notched
as at II to form a catch retaining portion IIa.
Rigid therewith is a centering strip I2 having
the vertical groove I 2a therein. This also is aper
tured as at I3, see Fig. l, to pass the catch mem
.
The lock structure includes a housing com
as a cam follower as it were for in that aperture
is mounted a disc 33 that serves as a cam or
eccentric.
'
Extending forwardly from the member SI is the
bolt portion 311 which is herein shown recessed as
at 35 purely for metal reduction purposes, and the
' forward end of said portion 35 terminates in a
hook 36 which has a curved nose 35a and a fiat
ber.
The closure associated with this stationary ele
ment or wall arrangement includes a lead post
I 4, also channel shaped, and this has its wings =
I5 arranged for suitable connection to the olo
sure proper. This is the lead post, and it is to
be understood that the closure is movable to
ward and away from the stationary post I0, and
the closure by means hereinafter to be described, 50
can be latched to that stationary post or locked
thereto as desired. The lead post Iii is also slot
ted as at IB, and the several slots, when the two
posts are positioned adjacent each other, are in
rearward face 3l which is the catching face.
Rigid with the eccentric 33 is the operating shaft
and this extends oppcsitely from said eccentric
and is rounded at 38a and is squared as at 3th as
shown. A sleeve IlI is provided in alignment with
the shaft 38. One of these is at each side of the
housing and located within the lead post. A cou
pling member 42 has a non-circular exterior and
a square cross section interior and telescopically
receives the squared end 38a of the shaft carrying
the eccentric 33. Extending through circular
holes 43 in the side portions of the lead post areA
the shafts M, also square, and these at their outer
ends carry suitable knobs, 45, masking plates 46,
etc.

be raised and retracted from the locked position
in Fig. 1 for closure opening or can be projected
and dropped into locking position as shown in
Fig. 1.
The plate 46 previously mentioned is extended
Herein the upper guide member is recessed as at
160 to clear or accommodate the eccentric 150.
Now when the eccentric 15B is locked in the
position as shown in Fig. 5, the upper end of the
guide stem 129 is engaged by said eccentric so
that the lock or bolt member cannot be verti
upwardly in the present instance and provided
cally reciprocated, and hence, the closure can
not be unlocked. When the eccentric 1511 is
with apertures 46a. The side portions of the lead
post are also apertured at 41" and a cylindrical

housing 48 is suitably retained in said aligned
openings and mounts within it the barrel of a '
cylindrical lock which is key actuatable from
either side in the present embodiment 'of the in

and then two bearing members can elevate and

Now when it is desired to lock the bolt in the
locked position, the member 50 is positioned as
