‘I
This invention has to do with improvements
in spring latches and consists of the hereinafter
described novel combinations and arrangements
of parts together with parts which, in themselves, are novel, by virtue of which I aim to
provide a spring latch which is economical of
manufacture, durable, and in which the latch
lever is yieldably but positively held in the desired position by novel means.
Other objects and corresponding accomplishments will appear obvious to those skilled in the
art from the following description wherein, by
way of example, I describe a preferred embodie
ment of the invention. In this connection, however, I wish it understood that while I resort
in this description to various details of combinations, arrangements and parts, my invention,
in its broader aspects, is not to‘ be restricted to
such details. On the contrary, it is to be restriated only as appears from the appended
ment with the latch keeper, the roller being held
against longitudinal escape from the lever by a
washer 3| held in place by heading the end of
the latch lever as shown at 32.
For yieldably holding the latch lever in either
its open or closed position, I provide a leaf
spring 40, which rests as one end on body lug
Ill and at its other end it rests against and has
a portion 42 projecting downwardly into a coil
spring 44 vertically mounted in the casing and
socketed between body lug 46 and one side of
the body I I]. Spring 40 is undulated so as to
present substantially at its medial portion a
raised portion 47 with relatively lower portions
48 and 49 on each side thereof. The lug 24
has a curved face which slides over the raised
spring portion 47 when the latch lever is moved
between its open and closed positions, and since
coil spring 44 at all times additionally urges
leaf spring 40 against lug 24, the latch lever
claims.

For purposes of the following description, I
shall make reference to the annexed drawing, in
or closed position.
To manually move the latch lever about post
which:
Fig. 1 is a back view of my latch, in elevation,
I8, which acts as a fulcrum for the lever, I pro
vide a handle 50 pivotally mounted on the ex- 25
with the parts in latching position;
Fig. 2 is a view similar to Fig. 1 except that
the parts are in open or unlatched position;
Fig. 3 is a side elevation of my latch;

Fig. 4 is an elevation showing the latch lever
in engagement with the keeper;
Fig. 5 is a section on line 5—5 of Fig. l; and
Fig. 6 is a front elevation of my latch and
keeper.
terior of the body between a pair of lugs 5I by a
pin 52 extending through the lugs and an open
ing through the handle. This handle member
has a ?nger 54 projecting through body slot 55
into the body between latch-member ?ngers 20, 30
2!. Thus as handle 50 is moved about its pivot
pin 52, ?nger 54 acts to swing the latch lever
to open or closed position.
An overhanging portion 6!! of handle 50 pro

My latch has a metal housing
Hl having
?anges I I through which holes I2 are provided
for securing the device to the face of a door.
Within body I0 latch lever I5 is pivotally secured to post I8 by screw I6, a washer I‘! being
provided between the screw-head and the top
of post I8, the latch lever being rotatable about
post I8. Lever I5 is bifurcated at its inner end
to present spaced ?ngers 20, 2|, and at what
may be termed the under side of lever I5 there
is a lug 243 which presents a curved face.
Body I!) has at one of its sides a vertical slot
25 between body portions 26 and 21, which latter portions serve as stops for the outwardly
projecting portion I5a of the latch lever to
limit its vertical movement. Thus lever portion
I5a rests against stop 26 when the latch is open
(Fig. 2) and against stop 21 when in latching
position (Fig. 1). At its outer end the latch
lever has a portion I5b of reduced diameter,
around which is provided a roller 30 for engage-
inserted for locking purposes.
The operation of my device is as follows: To
move the parts from the latched position of Fig.
1 to the open position of Fig. 2, the handle
member 50 in Fig. 3 is moved to the right, which
causes ?nger 54 to move latch member 2I
downwardly, which in turn raises the outer end
of the latch lever until it abuts stop 26 and re
moves it from engagement with the latch keep
er 35, during which movement lug 24 rides over
hump 41 of leaf spring 40. Also during this
movement, the roller 3!} rolls over the upwardly
and outwardly tapering surface 36 of the keeper
to urge the door, to which body I0 is secured,
outwardly. To again latch the door, it is only
necessary to push the door closed, by virtue of
which pressure the roller 30 rotates in the re
verse direction against keeper face 36, which
moves the outer end of the latch lever I5 down
wardly until lug 24 is moved slightly over the

center of hump 4‘! of spring 40, after which
bolt in a predetermined position, including: a
the pressure of spring 40 and coil spring 44 com—
lug on the side of the bolt substantially opposite
said pivot member, a leaf spring bearing against
the lug and a coil spring bearing against one end
of the leaf spring to urge it against the lug.

pletes the closing action, automatically swing
ing the latch lever until its portion l5a abuts
stop 21. >
From the foregoing it will be observed that
in order to move latch lever l5 from either its
open or closed position, enough pressure must
be exerted to move lug 24 over hump 41 of
10 spring 40, which precludes any accidental open;
ing or closing action. Furthermore my device is
easy to assemble or repair inasmuch as the latch
lever and latch handle are the only parts se
15
cured to the casing.
Iclaim:
1. In a latch device having a body, a latch
2. In a latch device having a body, a latch
bolt, a pivot member'connecting said bolt be
tween its ends to the body, said pivot member
extending through a side portion of the bolt, a
bolt actuating member operatively associated 10
with one end of the bolt to move the bolt about
the pivot member, and means for yieldably
holding the bolt in predetermined position, in
cluding: a lug on the side of the bolt substan
tially opposite the pivot member, a leaf spring 15
rockably resting at one end against the body
bolt, a pivot member connecting said bolt be-'
and a coil spring urging the other end of the
tween its ends to the body, a bolt actuating
member operatively associated with one end of
leaf spring against said lug.
