ABSTRACT OF THE DISCLOSURE
Conventional gate latches include a latch bar on the gate and a latch bar receiver on the adjacent gate post.
Both gates and fences often become misaligned so that the latch bar no longer enters the receiver jaws. In this de-vice, the receiver is provided with diverging jaws and the latch bar is mounted so that if it is misaligned with the center of the receiver jaws, it can be urged into alignment by the diverging jaws. The latch bar is mounted for limited vertical movement and is held frictionally to a carrier plate secured to the gate.

Description
BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-ments in gate latches, particularly gate latches of the type which include a horizontally extending latch bar secured to the free side of the gate and a recelver assembly mounted on the member against which the gate engages when-it is closed. When the bar enters the jaws of the receiver, a latch is displaced and falls behind the latch bar thus ;
holding it securely within the receiver and when it is de-sired to open the gate, this latch is actuated thus clear- ~-ing the latch bar so that the gate can be swung open.
It is well known that gates and/or fences often become misaligned due to moisture conditions, sub soil move-ment and the like so that the latch bar will no longer enter the receiver without disengaging one or the other from the support thereof and re-positioning same.

Also, gate hinges often develop looseness so that the gate sags slightly. Under these circumstances, the gate has to be lifted by the operator in order to align the latch bar with the receiver every time the gate is closed.
SUMMARY OF THE INVENTION
The present invention overcomes these disadvan-tages by providing automatic limited adjustment of the latch bar each time the gate is closed.
One aspect of the invention provides, in a gate latch assembly for securement to adjacent the free outer side of a gate and the adjacent member against which the gate closes; a latch bar receiver assembly securable to the said adjacent member and a latch bar assembly securable ad-jacent to the outer side of 'che gate and in substantial alignment with said receiver assembly whereby said latch bar assembly cooperates with said receiver assembly to re-leasably secure said gate in the closed position, said re-ceiver assembly including open sided jaws, said latch bar ~. .
r` assembly including a latch bar, said latch bar including an outer portion and an inner portion, said latch bar be-~ ing receivable within said jaws by the outer portion there-!, of, and means mounting said latch bar for limited movement in a vertical plane, said last mentioned means including ~;
further means to apply con'crolled resistance to said limited movement.

vice which is simple in construction, economical in manufacture and otherwise well suited to the purpose for which it is designed.
With the foregoing objects in view, and other such objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists es-sentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

Figures 5 and 6 show front elevations of the latch bar assembly per se with the latch bar in -the upper-most and lowermost positions respectively.

DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference character 10 illustrates the outer free portion of a gate having a latch bar assembly collectively designated 11, secured thereto.
Reference character 12 illustrates a fence post terminating a length of fence 13',to which is secured a latch bar receiver assembly collectively designated 13.
In detail and referring to the latch bar receiver assembly, a mounting plate 14 permits the assembly to be secured to the post 12 by means of screws 15 in the usual way with a pair of jaws 16 extending beyond the outer sur-face 17 of the fence post, said jaws being open sided in the area indicated by reference character 18.

extending above the jaws 16 and a latch bar engaging por-tion 22 extending into the area between the jaws 16.
Under normal operations, a latch bar of a gate enters the jaws, displaces the portion 22 so that the latch bar can pass thereby to take up the position shown in phan-tom by reference character 23 whereupon the latch 19 re-turns to the position shown in Figure 1~ In order to dis-engage the latch bar 23, the portion 21 of the latch is moved towards post 12 thus displacing the portion 22 in the opposite direction so that the latch bar 23 can be moved clear of the jaws and the gate opened.
~ ~' In the present device, the jaws 16 are provided :
with outwardly divergent latch bar entry portions 24 as clearly shown in Figure 1.
., ,.; .
The latch bar assembly 11 includes a substantially ~: .
conventional latch bar 23 hereinbefore mentioned, comprising a round section outer portion 24'usually provided with an ;~;
enlarged outer end 25.
The inner portion specifically designated 25'is is flattened slightly to facilitate attachment and in the present embodiment, it is attached to a latch bar mounting -plate collectively designated 26.

: ' ' . ' - This plate includes attaching flanges 27 for : :
~: ~: ' ' ' , ,' '; ,: ,, . '. ' : ' ' ~4~t;SS2 securement to the gate 10 by means of screws 28. The central portion 29 is si-tuated in a plane spaced from the plane of the flanges 27 to define an area 30 which receives the inner portiorl 25' of the latch bar 23.
A pair of vertically situated closed ended elon-gated slots 31 are formed through this central portion 29 and the inner portion 25' of the latch bar is secured to the inner surface of the central portion 29, by means of fastening assemblies 32 which extend through the slot and through apertures or screw threaded drillings provided with-in the portion 25' of the latch bar.
Means are provided to control the frictional en-gagement of the latch bar to the plate 26 and in this em-bodiment, this means takes the form of spring washers 33 situated between the screw head 34 and the nut 35 of the fasteners 32. Alternatively, of course, other frictional controlling means may be provided such as fibre washers, or the like.
By adjusting the tightness of the fastening as- ~:
semblies 32, the frictional engagement of the inner end :
25' of the latch bar is controlled relative to the central portion 29 of the plate 26. ~ .
In operation, and under normal circumstances, the latch bar 23 is mounted substantially hori~ontally ; ' .
;5S2 as shown in Figures l, 2 and 4 whereupon it enters the center of the jaws 16 when the gate is closed. However, if the gate and/or post becomes misaligned one with the other, then the outer portion 24'of the latch bar 23 will strike the divergent entry portions 24 of the jaws 16 which will force the latch bar to the necessary position so that it will enter the jaws and operate the latch.
; Figures 5 and 6 show, in a somewhat exaggerated relationship, the relative movement of the latch bar in the uppermost and lowermost positions respectively.
By controlling the pressure of the fastening as~
semblies 32, the force required to move the latch bar, may be controlled within limits so that the bar will automatic-`~ ally adjust to the jaws and correct any misalignment which may occur. ~
