DOOR LATCH.

Application filed Getober 1, 1926. Serial No. 138,836.

The present invention relates to door latches; and its object is to provide such a latch which shall be simple in construction, comprising parts readily assembled, and having a latching bolt swingable in either direction into and out of latching engage ment with its keeper and held yieldingly in operative or retracted position.

These and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the door latch hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which Figure 1 is a face view of a door latch;

Figure 2 is a left-hand side view thereof;

Figure 3 is an inner side view of the latch casing, showing operative parts therein, the latching bolt being in operative or latching position;

Figure 4 is a like view, but showing the latching bolt in a retracted position and aportion thereof broken away;

Figure 5 is a sectional view of the same taken on line 55 of Figure 3; and

Figure 6 is a view in perspective of the latch casings inner side.

In the embodiment of the invention illustrated by the accompanying drawings, a door latch is shown mounted adjacent the left-hand free edge of a swinging door 1, the latchs keeper 2 being mounted an the door frame 3. The latch has a casing which a latching bolt 5 is mounted to swing into and out of operative position in which its outer end (3 latchingly engages thekeepcr. 'lhis bolt has

members

8, 9 spaced. apart in tho bolts transverse direction, which members turn and slide in

bearings

10, 11

respectively in the right-hand wall 6 of the casing, through which bearings the ends of these members extend. The opposite wall 16 of the casing, adjacent the keeper, has a bearing orilice 17, the keeper-engaging end 6 of the bolt projecting through, and sliding in, this bearing. The bolt is held in position in the casing by its said end 6 and

members

8, 9 extending through the

bearings

17 and 10, 11 respectively.

It will be seen that, when the handle portion 14 of the bolt is moved downwardly to disengage the end 6 from the keeper, the upper member 8 turns on its bearinglO while the lower member 9 slides in its bearing 11'; and that, if the latch be mounted adjacent 4-, inside the right hand free edge 01. a swinging door,

so that the ends of the casing be now reversed in position, the downward movement of said handle portion to disengage the bolt from the keeper causes the member 9 to turn on its bearing 11 while the member 8 slides in its bearing 10. It will thus be seen that the same latch may be mounted either at the right-hand or left-hand edge of a swinging door.

An element 20 has a movement in the casing toward .and from the keeper, being slidably mounted as by thecasings attaching screws 21 extending through slots 22in said element. The bolt 5 has a lateral extension, such as the lug 23 extending through an opening 24 in said element 20 and adapted to seat in any one of a plurality of recesses or seats in said element adjacent the outer wall of said opening and arranged transversely to the direction of its movement.

The middle one, 25, of these recesses re ceives this extension 23 of the bolt to hold the same in latching position, and the upper recess 26 receives said extension to hold the bolt retracted to the position seen in Figure 4, while the lower recess 27 receives said extension to hold the bolt in its other retracted position. i

A spring 28 abutting at 29 on the-wall 16 of the casing, presses said element 20 rearwardly or toward the casings wall 6, to yieldingly hold said extension 23 in said recesses respectively and to press the

bolts members

8, 9 in their

bearings

10, 11.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.

I claim:

1. A latch comprising: a bolt provided with. a lateral extension and having a swinging movement into and out of latching position about an axis offsetfrom the direction of the pressure of the hereinafter-1nentioned spring; an element having a movement in the longitudinal direction of the bolt and provided with a plurality of recesses arranged transversely to the direction of its movement receiving said extension in the bolts latching and retracted positions respectively; a springpressing said element to yieldingly hold said extension in the recesses respectively.

2. A latch comprising: a bolt provided with a lateral extension and having a swinging movement into and out of latching position about axes offset from the opposite sides of the direction of the pressure of the hereinaitenmentioned spring; an element having a movement in the longitudinal direction of the bolt and provided with a middle recess and recesses spaced from its opposite sides transversely to the direction of said elements movement; a spring pressing said element to yieldingly hold said extension in the middle recess in the bolts latching position and in the other recesses respectively in the bolts retracted positions.

3. In a door latch: a pair of spacedbearings; a belt having a swinging movement into and out of latching position in the keeper and provided with a lateral extension and a pair of members spaced in the bolts transverse direction, one of'said members being movable slidably and the other or" saidanembers being movable turnably in the bearings respectively in the bolts movement; an ele ment having a movement in the longitudinal direction of the bolt and provided with a plurality of recesses arranged transversely to the direction of its movement receiving said extension in the bolts latching and retracted positions respectively; a spring pressing said element to yieldingly hold said extension in the recesses respectively.

4. In a door latch: a casing having adjacent the free edge of the door a bearing and having a pair of spaced bearings disposed oppositely to the first-mentioned bearing; a bolt having a swinging movement into and out of latching position, said bolt extending through the first-mentioned bearing and provided with a lateral extension and a pair of members spaced in the bolts transverse direction and extending through said pair 01"" bearings respectively, one of said members being movable slidably and the other of said members being movable turnab-ly in said pairof bearings respectivelyin the bolts movement; an element having a movement in the longitudinal direction of the boltand provided with a. plurality of recesses arranged transversely to the direction of its movement receiving said extension in the bolts latching and retracted positions respectively; a spring pressing said element to yieldingly hold said extension in the recesses respectively.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this th day of September, 1926. V

ELMER C. OSBECK.
