[ 1 June 24, 1975 Primary Examiner-Robert L. Wolfe Attorney, Agent, or Firm-Clarence A. O'Brien; Harvey B. Jacobson 1 ABSTRACT A mount is provided for securement to the upper portion of a fence post and with an upper portion of the mount projecting above the associated fence post. A first L-shaped operating lever is pivotably attached at the free end of its short arm to the upper portion of the mount for swinging of the operating lever about a horizontal axis extending transversely of an associated fence and a plane containing the short and long arms of the operating lever and the free end of the short leg of a second L-shaped lever is pivotably attached to the base end of the long arm of the operating lever adjacent the short arm thereof with the free end of the long leg of the second lever being provided with an chor structure engageable with a wire gate end post.

6 Claims, 5 Drawing Figures WIRE GATE LATCH BACKGROUND OF THE INVENTION Similar wire gate latches are disclosed in prior U.S. Pats. Nos. 564,162 to G. Roth, dated July 14, 1896; 882,692 to G. O. Kidder, dated Mar. 24, 1908, 2,575,947 to E. A. Etnyre, dated Nov. 20, 1951 and 2,613,972 to M. E. Gifford, dated Oct. 14, 1952.

However, some of these prior wire gate latches include actuating lever portions which are supported from the associated wire gate end member as opposed to from an adjacent stationary post member and these wire gate end member mounted levers are difficult to actuate due to their being pivotably supported from reasonably freely movable support portions. In addition, while some wire gate latch constructions may be provided with pivotable actuators supported from stationary post members, the latch construction of the instant invention includes structural features whereby it may be relatively easily actuated and yet be capable of exerting considerable tensioning forces on an associated wire gate.

Further, the wire gate latch specifically describe and claimed hereinafter utilizes readily available components requiring only simple manufacturing processes.

BRIEF DESCRIPTION OF THE INVENTION The latch is mounted on an associated stationary post as opposed to a relatively freely movable wire gate end in order to enable the actuator of the latch to be more positively operated. Also, the latch includes an operative association with an adjacent wire gate end such that varying spacing between the wire gate end and the post upon which the latch is mounted may be readily compensated for.

It is the main object of this invention to provide a wire gate latch which will be easy to operate and yet which will be capable of heavily tensioning an associated wire gate while securing the latter in a closed position.

Another object of this invention is to provide a latch construction which may be more positively actuated.

A final object of this invention to be specifically enumerated herein is to provide a latch construction in accordance with the preceding objects and which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.

These together with otherobjects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the latch of the instant invention operatively associated with fragmentarily illustrated portions of a supporting fence post and an associated wire gate and with the latch in the closed posi' tion;

FIG. 2 is a top planned view of the gate latch;

FIG. 3 is an enlarged, fragmentary vertical section of the view taken substantially upon the plane indicated by the sectional line 3-3 of FIG. 1;

FIG. 4 is a side elevational view of the gate latch in a closed position; and

FIG. 5 is a side elevational view of the gate latch in open position.

DETAILED DESCRIPTION OF THE INVENTION Referring now more specifically to the drawings, the numeral designates a fence post defining one side of an opening through a fence, and the numeral 12 designates an end upright of a wire gate 14 to be tensioned across the fence opening.

The latch of the instant invention is referred to in general by the reference numeral 16 and includes a mount 18, first and second L-

shaped levers

20 and 22 and an attaching and tensioning loop 24. The mount 18 comprises a relatively thick strap 26 of metal. The strap 26 is vertically disposed and includes relatively twisted upper and

lower sections

28 and 30. The lower section 28 is provided with a pair of vertically and longitudinally spaced apertures 32 and the upper section is twisted 90 degrees about the longitudinal centerline of the strap 26 relative to the lower section 28. The lower section 28 is secured to the side of the post 19 remote from the fence opening by means of fasteners 34 secured through the apertures 32 and embedded in the post 10. The upper terminal end of the upper section 30 projects above the post 10 and has the free end of the short arm 36 of the first lever 20 pivotably secured thereto by means of a fastener 38 secured through the free end of the short arm 36 and the upper terminal end of the upper section 30. The lever 20 includes a long arm 40 and comprises a pair of spaced side-by-side L-

shaped members

42 and 44 joined by means of an integral reversely bent portion 46 at the free end of the long arm 40.

A short elongated stop bar 48 has one end thereof secured to the mid-portions of the L-

shaped members

42 and 44 defining the long arm 40 in any convenient manner such as by welding, and the bar 48 prejects outwardly from the long arm 40 toward the central portion of the lower section 28 of the mount 18 disposed between the apertures 32 for abutting engagement with the lower section 28 in the area 50 thereof, see FIG. 3.

The lever 22 includes a short leg 52 and a long leg 54 and the free end of the short leg 52 is pivotably secured between those portions of the L-shaped

members

42 and 44 defining the end of the long arm 40 adjacent the short arm 36 by means of a fastener 56. In addition, the free end of the long leg 54 of the lever 22 is twisted 90 about the longitudinal centerline of the long leg 54 and is provided with a reverse returned hook portion 58 with which one end of the elongated loop 24 is releasably engaged.

The upright or stick 12 has one end of the loop 24 secured thereabout by means of staples 60 holding the loop 24 firmly in place on the stick 12 against sliding therealong.

In operation, attention is invited to FIG. 5 of the drawings wherein it will be seen that the latch 16 is in the open position with the wire gate 14 in an untensioned condition and the upper end of the upright 12 inclined away from the upper end of the post 10.

Assuming that the reversely bent portion 58, carried by the free end of the long leg 54 of the lever 22, is engaged with the loop 24 the free end of the long arm 40 is swung in a counterclockwise direction as viewed in FIG. 5 of the drawings to the position thereof illustrated in FIG. 4 of the drawings with the abutment bar 48 abutted against the lower section 28 of the mount 18. In this position, the pivot fastener 56 is swung to an over center position of the underside of a straight line extending through the fastener 38 and the end of the loop anchored to the stick 12. Thus, the tension of the wire gate 14 serves to resist movement of the lever 20 in a clockwise direction away from the position thereof illustrated in FIG. 4.

By utilizing the lever 22 instead of merely providing the lever 20 with a notch or reversely bent portion in which the end of the loop 24 could be engaged, the operating lever 20 may be readily positioned on the side of the post remote from the wire gate 14. In addition, the provision of the lever 22 enables a substantially horizontal pull to be exerted on the loop 24 and thus minimizes any tendency of the upright 12 to be shifted vertically as the wire gate 14 is being tensioned and latched in the closed position. Also, by positioning the mount 18 on the side of the post 10 remote from the wire gate 14, a reasonably simple mounting of the mount 18 on the post 10 will be capable of resisting the tension stresses applied on the wire gate 14 by the latch 16.

Further, it is merely necessary to utilize a loop 24 of a different length in order to vary the tension of the wire gate 14 and to compensate for varying distances between the post 10 and the upright 12.

The foregoing is considered-as illustrative only of the principles of the invention. Further since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
