GATE LATCH Filed June 15, 1956 IN V EN TOR.

ATTORNEY United States Patent GATE LATCH Lloyd A. Taylor, Oklahoma City, Olda. Application June 15, 1956, Serial No. 591,690

2 Claims. (Cl. 292-218) The present invention relates to gate latches, and more particularly to a gravity actuated latch for fastening a horizontally hinged gate.

The principal object of the present invention is to provide a gravity actuated latch for fastening a self closing hinged gate.

An equally important object is to provide a gate latch having a lever which is lifted by a fixed pin carried by the free end post of a hinged gate for securing the gate.

Another object is to provide a gate latch having a lever which may be manually released from either side of a closed gate.

Another object is to provide a gate latch of this class which is sturdily constructed and has only one moving part.

A further object is to provide a gate latch of this character which will permit a hinged gate to be released therefrom and opened in either direction.

Yet another object is to provide a gate latch of this class which is provided with means for locking the latch against unauthorized entry.

The present invention accomplishes these and other objects by providing a substantially rectangular body adapted to be rigidly secured transverselyto the forward side of a fixed post adjacent a fixed pin or projection carried by the free end post of a hinged gate adjacent but spaced-apart from the fixed post. The body further includes a rigid flange along its longitudinal upper edge projecting forwardlytoward'the free end post of the gate. An arcuate edged depending guide is integrally carried centrally by the lower surface of the flange. A forwardly projecting stop is integrally carried by the body below the flange adjacent each outer lower end portion. A face plate is removably connected to the forward side of the body in contact with the flange and stops and forms a slot therebetween. An elongated release lever is longitudinally disposed within the slot and projects outwardly beyond the ends of the body. A registering recess is formed in the lower surface of each end portion of the lever for receiving the stops and preventing longitudinal movement of the lever relative to the body. Integral depending lip portions define a central rectangular downwardly opening pin receiving notch. The lower surface of. each lip portion is beveled outwardly and upwardly from the lowermost portion of the lip portion so that the pin carried by the gate strikes the beveled surface to raise one end of the lever to permit the pin to enter the notch. The upper surface of the lever is provided with upward arcuately curved flanges for contacting the guide and maintaining one of the registering recesses in contact with the adjacent stop when the opposite end of the lever is raised.

Other objects will be apparent from the following de scription when taken in conjunction with the accompanying single sheet of drawings, wherein:

Figure 1 is aperspective view of one embodiment'of the device installed on a fixed post, the f xed post and associated gate post being shown in dotted lines;

Like characters of reference designate like parts in those figures of the drawings in which they occur.

In the drawings:

The reference numeral 10 indicates, as a whole, the latch comprising a substantially rectangular body 12 having a forward side 14, a rearward side 16, and a hollow interior 18. The rearward side of the body is provided with a central semi-circular recess 20 having serrations 22 perpendicular to the longitudinal axis of the body. The serrated recess 20 is adapted to contiguously contact a peripheral portion of the forward side of a fixed tubular post 24 adjacent but spaced from a free end post 26 of a horizontally hinged gate. The free end post 26 rigidly carries a pin 27 projecting at its free end toward and under the forward side of the body in closely spaced relation. As shown in Figs. 1 and 2, the body is centrally perforated, as at 28, for receiving a bolt and nut 30. The bolt 30 extends rearwardly through the recess 20 and projects through the fixed post 24, thus rigidly connecting the body transversely of the post. Other means of rigidly connecting the body 12 to the post 24 is shown in Fig. 4 and includes a substantially U- shaped clamp element 29 co-operatively recessed and serrated with relation to the recess 2%). The clamp 29 is disposed transversely of the post 24 in co-operative alignment with the body 12 and has perforated ends for receiving bolts and nuts 31 carried by the rearward side 16 of the body on each side of the recess 26. This clamping means permits vertical adjustment of the device 18 relative to the post 24, for reasons more fully explained hereinbelow. The forward upper side of the body is provided with an integral longitudinally extending flange 32. A web-like guide 34 is integrally carried in depending relation by the central portion of the flange. The lower surface of the guide 34 is arcuately curved longitudinally upwardly from its lowermost surface toward each end of the body to merge with the lower surface of the flange 32. Stops 36 and38are integrally carried by the lower forward end corners of the forward portion of the body and extend forwardly equidistant with the flange 32. A face or cover plate 40 is removably connected by screws 41 to the forward side of the body in contact with the flange 32 and the stops 36 and 38, thus forming a slot 42 between the plate and the body.

A release lever 44 is longitudinally disposed within the slot 42 and projects outwardly beyond each end of the body. The thickness of the lever 44 is less than the width of the slot 42 and transversely the width of the lever is such that the same may be freely moved vertically within the slot, for the reasons which will presently be apparent. Arcuate recesses 43 and 45 formed in the lower surface of the lever adjacent each end portion cooperatingly receive the stops 36 and 38, respectively, and support the lever. Intermediate the recesses 43 and 45 the lever 44 is provided with a pair of integral depending lip portions 46 and 47 havingopposing vertical sides 48 and 49, respectively, defining a rectangular notch 5% for receiving the free end of the pin The lower surface 52 of the lever defining the upper edge of the notchfiti is substantially parallel with the lower surface of the body 12 when the lever is in its downward or latched position. The lower surface of each lip portion-46 and 47 is. beveled outwardly and upwardly, as at 54, toward the adjacent recess 43 or 4.5.; Thus, when the gate is closed the free end of the pin 27 strikes the beveled surface 54 raising the adjacent end of the lever and allowing the pin to enter the notch 50.

The upper surface of the lever is provided with a pair of integral centrally spaced-apart flanges 56 having arcuate upper edges for contacting the adjacent lower surface of the guide 34 when one end of the lever is raised. Thus, the flanges 56 and the guide 34co-act to maintain the lever in operating position within the slot 42 during opening and closing action of the gate. The outermost ends of the lever 44 are transversely flattened, as at 58, for manually grasping the lever to lift the same at one end and release the pin from engagement within the notch 50.

Each lip portion 46 and 47 is transversely perforated adjacent the lower surface of the body, as at 60, for receiving suitable locking means, not shown, for locking the lever in closed position.

Operation The latch is installed as disclosed hereinabove, and when the gate is moved toward a closed position the free end of the pin 27 strikes the adjacent beveled surface 54 of the lip portion 47 and raises the adjacent end of the lever, as shown by dotted lines, Fig. 3. The pin 27 raises the adjacent end of the lever by pivoting the recess 45 on the stop 38 until the lowermost portion of the lip portion 47 adjacent the pin 27 is substantially parallel with the lower surface of the body, thus allowing the pin to pass under the lowermost portion of the lip portion 47. The pin 27 has then entered the notch 50 and momentum of the closing gate causes the pin to strike the straight edge 48 of the lip portion 46 which pivots the raised end of the lever back to its downward or closed position. The flanges 56 and the guide 34 limit the upward movement of the lever, thus insuring that only the adjacent lip portion is raised above the pin to prevent the gate being swung beyond the closed position.

The gate may be opened by manually raising one end of the lever, thus allowing the pin 27 to be passed under the adjacent lip portion. The lever 44 is normally held in its downward latched position by gravity.

The preferred means of clamping the device 10 to the post 24, as disclosed by Fig. 4, permits vertical movement of the device relative to the post to properly position the lower surface in closely spaced relation above the pin 27 in the event that the gate has sagged or become out of line, causing the pin 27 to become misaligned relative to the slot 50 in the lever.

Obviously the invention is susceptible to some change or alteration without defeating its practicability, and I therefore do not wish to be confined to the preferred embodiment shown in the drawings and described herein,

further than I am limited by the scope of the appended claims.
