This invention relates to fasteners for swing
ing or sliding closures, such as doors, windows,
drawers and the like.
Figures 3, 4, 5 and 6 are cross sections on the
lines 3_3, 4_4, 5--5 and 6--6, respectively, of
Figure 1.
In many instances it is desirable that a closure
have a frame, the stiles or equivalent elements
of?which are of narrow width. For example, in
the case of hospital windows and hospital doors
nates a portion of a closure frame and B desig
nates a portion of an associated closure which,
having transparent panels, it is desirable that the
door hinged at one side for swinging movement
stiles be of as narrow width as practicable in
between open and closed positions.
Referring to the drawing in detail, A desig
for present purposes, may be considered as a
order that the windows and doors may admit 10

The door B includes a frame b and a vpanel b'
which, in the present instance, is illustrated as
being of transparent material, although it may be
in instances where the doors or windows are of
narrow width. Also, it is quite desirable in many
instances to provide a closure fastener embody
of any other material. In any event, the frame
b includes top and bottom cross members, only

portions of which are shown, and vertical ?side

Thelatch orlock bolt 25 is pivoted intermedi
ate its ends and adjacent to oneedge thereofY
upon the pin 25 and includesa latching or locking ,
portion 2T which, by ,rotation of said bolt in one
direction through an angle of approximately
Y 'net-y degrees, is proiectable to a latching or lock
ing position Yin which it extends beyond the stile
wall I2; i. e., beyond the free 'edgeof the, door, as
shown, and which, yby krotation of said locking bolt
in the opposite directionthrough. an angle of ap
proximately ninety degrees, is retractable to an
'unlatched or unlocked position in which it is dis- ,
posed entirely within thestile b? ?.
� i
` The portion 2'.' is substantially in the form of a
ninety-degree segment of a circle as viewed* in side
elevation and its inner face is of substantially
conical remi; i. e., its inner face is beveled both
longitudinally and transversely away from the
pivot pin 25. Consequently,-should the portion` 21
- be in its projected position duringclosing of the
22 and' ?23 coi'istantly outward to .their limits of
outward movement as determinedby engagement
oi' the walls at the inner ends of the slots v38 in
the stems 3l with the pins韎�. In this connection,
the constructionobviously is such `that if the latch
orlockY bolts 22 >and 23 are projected as shown`
in lFigure __1, they will be retracted by inward
movement ofthe rods 35, 35 and the tubes 36, 36.
At the sameY time, the construction is such-that
even though the rods
35 andthe tubes .35, -35
are not movedlinwardly, the latch or lock bolts22
and 23 are free to be moved inwardly against the
springs遉, 42. vIn short?the籨escribed construc
tion provides Yfor positively retractinglthe latch
or lock vbolts 22, 23 when itis desired to` open the
door` and, at the same time, provides for auto
matic retraction of said bolts by engagement of
their beveled inner faces with theirrelated keep
ers topermit the door to be closed, as well as for
subsequent spring projection of said bolts totheir
door latching or locking positions when the door
i is closed.

k44 Vand 45. The pinion 45 may?appropriately be
mounted in a suitable frame 41 suitably fastened
in the channel member It. In any event, it is
apparent that the springs 42 tend constantly-to
project both latch or lock boli-s 22 and 23 and
to shift the block Z9 upwardly, and that by down
ward movement of said block 2S, both latch or
lock bolts 22 and 23 will be retracted. The block
2B is, of course, shiftable downwardly to retract '
the bolts 22 and 23 by means of the handle 33
operating through the lever arm 3 l.
The lock or latch bolt 25 is located between the
block 29 and the upper biock 34 and, inwardly of
its pivot pin it, has projecting laterally therefrom
a pin 4l" over which extends a finger 48 which
projects laterally from the bar 43. Accordingly,
when the bar 43 is shifted downwardly, the finger
G8 acts upon the pin 4l? to rotate the latch or lock
bolt 25 to its retracted position. On the other
hand, a suitable spring 49 is provided to rotate
said bolt 25 to its projected position when the
bar 43 and the finger 4a are moved upwardly.
Obviously, the finger 43 acts as a'stop engageable
by the pin 4i' to limit rotation of the bolt 25
mentioned pin and the adjacent end of said stem
and constantly urging said tube outwardly and
said bolt outwardly relative to said tube, and
means for manual actuation to move jsaid tube
inwardly and thereby retract said bolt.
