LATCH Filed June 4. 1931 gwwntoz am l Patented .lune 14, 1932 UNITED STATES PATEN'r ortica GORDON E. ROEDDING", OF GRAND RAPIDS, MICHIGAN, ASSIGNOB, TO GRAND RUAPII'E BRASS COMPANY, OF GRAND RAPIDS, MICHIGAN, A CORPORATION F MICHIGAN LATCH Application filed June 4, 1931. Serial No. 541,965.

rThe present invention relates to latches;

and its object is, generally, to provide an improved latch for a door closure adapted to be tripped from retracted position by the closing movement of the closure; and more particularly, to provide parts of such a latch and combinations of such parts operating in an in'iproved manner hereinafter appearing.

These objects are attained by, and the invention finds preferable embodiment in, the latch structure particularly described in the body of this specification and illustrated by the accompanying drawing, in which Figure 1 is a front elevational view of portions of a door closure and door jamb with a latch and its keeper mounted thereon respectively, the latchs bolt being indicated in its latching position;

Figure 2 is a horizontal sectional view thereof taken on line 2-2 of Figures 1 and 3;

Figure 3 is a vertical sectional view of portions of the same taken on line 3-3 of Figures 1 and 2;

Figure 4 is a free edge elevational view of the partly closed door closure with the latch thereon and an inner side view of the latchs keeper, its mounting screws being sectioned on line 4 4 of Figure 2; and

Figure 5 is a vertical sectional view of the latch taken on line 5-5 of Figure 2.

In the drawing is illustrated a latch mounted adjacent the free edge of a swingable door closure 1, and its keeper mounted on the edge of the ja-mb 2 of the door. The latch comprises a base member having a recessed body portion 3 mounted as by screws 4 on the inner side of the closure, and a hollow post portion 5 extending outwardly in the bore 6 through the closure, the spaced legs 7 of this post portion being seated at 8 in the body portion.

The body portion and the post portion have aligned bearings 9, 10 respectively in which is journalled a shaft 11 having on its outer $5 end a handle 12 for turning it. The recess 13 of said body portion contains a flat latch bolt 14 into whose elongated slot 15 the fiattened inner end 16 of the shaft extends, so that the bolt is carried by the shaft turnably therewith, and so that the bolt is tiltable on the shaft axially thereof, i. e; in the plane in which lies the axis of the shaft.

A spring 17 is coiled about the shaft engaging at its upper end at 18 thereon and at its lower end engaging on the base at 19. This spring torsionally urges the shaft in the direction which turns the bolt to latching or operative position shown in Figure 5 and indicated in Figure 1. When however the handle 12 is turned toward the left-hand side of Figure 1 to open the closure, the bolt is thereby moved from such latching position (in which it is stopped bythe stop 20) bearing on the surface 21 of the body portion 3 until the ledge 22 of said portion is reached, whereupony the spring, pressing in the shafts axial direction, tilts the bolt toward the bottom of the recess 18 of said body portion and into retracted position in which it is held by the ledge 22 as shown in Figure 4. Vhen the closure moves to closed position, the bolts under edge 23 strikes the upwardly-inwardly inclined surface 24 of the latchs keeper 25 mounted as by screws 26 on the edge 27 of the door jamb. This closing movement of the closure pushes the bolt off the ledge 22, and as such closing movement continues, the bolt rides upwardly on the keepers surface 28 to operative or latching position.

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

I claim:

1. A latch for a door closure comprising: a base having a ledge; a shaft journalled on the base; a latch bolt carried on the shaft turnably therewith to latching position and tiltable axially thereof; a spring coiled about the shaft, torsionally urging the same to turn the bolt to latching position, and in one position of the shaft tilting the bolt to retracted held position on the ledge; the latch having a keeper on which the retracted bolt strikes in the closures closing movement to tilt the bolt from the ledge. Y

2. A latch for a door closure, having a bore therethrough, comprising: a base having a body portion mounted on the inner side of the closure and a hollow post portion extending in the bore, the body portion having a ledge and said portions having aligned bearings; a shaft journalled in said bearings and having a handle on its outer end; a latch bolt carried on the shaft turnably therewith Y to latching position and tiltable axially thereof; a spring coiled about the shaft, torsionally urging the same to turn the bolt to latching position, and in one position of the shaft tiltin the bolt to retracted held position on the lege; the latch having a keeper on which the retracted bolt strikes in the closures closing movement to tilt the bolt from the ledge.

3. A latch for a door closure comprising: a base having a recess and a ledge; a shaft j ournalled on the base having a flattened end; a latch bolt in said recess having a slot receiving said iiattened end non-turnably but tiltably in the shafts axial plane; a spring coiled about the shaft, torsionally urging the same to turn the bolt to latching position, and in one position of the shaft tilting the bolt to retracted held position on the ledge; the latch having a keeper on which the retracted bolt strikes in the closures closing movement to tilt the bolt from the ledge.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this lst day of June, 1931.

GORDON E. ROEDDING.
