DOOR LATCH.

Application filed November 8, 1924. Serial No. 748,578.

To all who-m t may concern.'

p Be it known that I, ANDREW EKMAN, a subject of the King of Sweden, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Door Latches, of which the following is a specification.

The present linvention relates to latches for swingable doors, such as thel doors of refrigerators and the like; and its object is, generally, to provide an improved device of that character whereby such doors may be securely and tightly held shut, and may nevertheless be easily opened.

This and other and more specific objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which:

Figure 1 is a'front view of a latch carried by a swingable door and the keeper therefor carried by the jamb of the door;

Figure 2 is a like view of the sa1ne'.the front wall of the casing however being broken away on a vertical sectioning plane and the operating lever handle being sectioned on the same plane;

1 Figure 3 is a sectional view of the same taken on a horizontal plane corresponding to line 3 3 of Figures 1 and 2:

Figure 4 is a sectional view of the same taken on a vertical plane corresponding to line 4 4 of yFigure 5, the parts being shown in this view in the unlatching or inoperative 'position of theV bolt ofthe latch; and

Figure 5 is a sectional view of the same taken on a horizontal plane corresponding to line 5 5 of Figure 4.

In the drawings, my improved latch '1s shown mounted adjacent the free edge of a swingable refrigerator door 1, the keeper 2 of the latch being mounted on the jamb 3 of the door. On a round'rod or bearing member 5 inside the casing 6 of the latch, the bolt 7 of the latch is mounted, and has a sliding movement therealong and a rocking movement thereabout. This bolts lateral extension 8 latchingly engages the keeper 2, the bolt being movable slidably on the member 5 into and out of latching position. The bolt 7 has a vlug or projection 9 adapted to rest on a support or shelf 10, extending fromv the inner surface of the dle arm 16 is drawn outwardly into the position seen in Figure 4,*the short arm 17 engaging the surface 18 of the bolts saidportion, forces the bolt upwardly along the bearing member or rod 5; and when the bolts lug 9 is thus moved to a position above the support 10, the frictional engagement of said short arm with said surface 18 rocks the bolt about the axis of the bearing member 5 suiiciently to bring said lug 9 immediately over the support whereupon, the handle arm being released, the spring 11 presses the lug 9 on the support 10 to maintain the bolt in its inoperative or unlatching position seen in Figures 4 and 5. The surface 18 is somewhat inclined Vas shownr in Figure 4 to augment the friction of the short arm 17 thereon. As the door is swung to closed' position, its keeper-engaging outer end 8 strikes the inner approximately-vertical surface of the keeper or door `iamb and rocksv the bolt reversely,y thus moving` its lug 9 off of thc support 10, whereupon the spring 11 immediately presses the bolt downwardly and its keeper-engaging end 8 into latching` engagement in the socket 20 of the keeper, thus holding the door tightly shut.' This keeper-engaging end 8 of the bolt is preferably furnished with an anti-friction roll 21 adapted to ride up on the inclined outer-upper surface 22 of the keeper when the door is slammed shut.

The casing has an opening 23 in its lower wall through which extends a portion 24 of the bolt provided with an orifice or keeper 25 whichv is outside the casing in the latching or operative position of the'bolt seen in Figure 2. The bolt 27 ofa pad lock 28 may be passed through this keeper orifice to lock the door shut.

The ends 80 and 81 of the spring 11 may be so held or anchored, as shown in Figures 2 and 4, as to tension said spring torsionally to rock the bolt in the direction which presses the lug 9 into resting position on the support l0, thusJ supplementing or replacing the frictional action of the levers short arm l? on the bolts surface 18.

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

I claim:

l. In combination With a keeper therefor, a door latch comprising: a support; a bolt having a reciprocating movement into and out of latching engagement with the keeper and a rocking movement, about an axis disposed parallelly with the direction of said reciprocating movement, into and out of resting position on the support; an operating handle adapted to move the bolt out of latching position and into resting position on the support.

2. In combination With a keeper therefor, a door latch comprising: a support; a bolt having a reciprocating movement into and out of latching engagement with the keeper and a rocking movement, about an axis disposed parallelly with the direction of said reciprocating movement, into and out of resting position on the support; an operating handle adapted to move the bolt out of latching position and into resting position on the support; a spring pressing the bolt into latching position.

3. In combination With a keeper therefor, a door latch comprising: a support; a bolt having a reciprocating movement into and out of latching engagement With the keeper and a rocking movement, about an axis disposed parallelly with the direction of said reciprocating movement, into and out of resting position on the support; an operating lever handle engaging the bolt and adapted to move the same out of lat-ching position and into resting position on the support.

4L. In combination With a keeper' therefor, a door latch comprising: a support; a bolt having a reciprocating movement into and out of lat-ching engagement with the keeper and a rocking movement, about an axis disposed parallely with the direction of said reciprocating movement, into and out of resting position on the support; an operating lever handle engaging the bolt and adapted to move the same out of latching position and into resting position on the support; aspring pressing the bolt into latching position.

5. In combination With a keeper' therefor, a door latch comprising.: a support; a bolt having a reciprocating movement into and out of latching engagement with the keeper and a rocking movement, about an axis disposed parallelly with the direction of said reciprocating movement, into and out of resting position on the support; an operating` lever handle frictionally bearing on the bolt and adap ed to move the same out of late-hing position and into resting position on the support; a spring pressing the bolt into latching position.

6. In combination with a keeper therefor, a door latch comprising: a support; a bearing member; a bolt mounted on said member slidably into and out of latching engagement With the keeper and rockably, about an axis disposed parallelly with the direction of said reciprocatingmovement, into and out of resting position on the support; a lever having a handle arm and an arm frictionally bearing on the bolt, and adapted to move the same out of latching position and into resting position on the support; a spring pressing the bolt into latching position.
