Description
This invention relates to a gate closure of the type use in pulling a stretch gate tight during closure of the gate and or holding the gate closed or used when it is desired to pull a stretch gate taut for removing an upper wire loop so as to be able to open the gate.
It is coon practice to close fence openings by the use of a plurality of lengths of wire, such as barbed wire, or even a length of page wire, by attaching the wire to a first stationary post at one side of the opening and to lo a movable post at the free end of the wire, which movable post is pulled to a position adjacent a second stationary post at the other side of the opening so that the lengths of wire is pulled taut across the opening. The movable post is usually attached to the second stationary post by placing the bottom end of Ire post in a loop of wire attached to stationary post near -the ground, and a second loop of wire may be provided near -the top of the stationary post so that it flay be dropped over the top of the movable post as the wire is pulled tight, The forming of a gate in this manner is very economical as compared to a framed gate which is attached by hinges to a stationary post. It lo difficult, however, for an individual to pull the stretch gate by hand sufficiently light for placing the top loop in place when closing the gate or for removing the loop when removing the loop. IF the loop is sufficiently loose to be able to be opened by hand, the gate may not be kept sufficiently taut to provide a good closure.
Numerous gate closure devices have been developed through the years for providing leverage in drawing the OW/ 1 rj~
:~;3~12~
stretch gate to a closed condition. Some of the known devices are of atvpe which require considerable labor for installing, and then must remain permanently connected to the post. The known type which requires drilling of post for inserting a rod as a pivot axis have been found to weaken the post.
though some of the known type of gate closure devices have been provided with latches to prevent accidental opening of the device, the devices may not be readily locked, with a conventional padlock, for example, so as to deter the public from using the gate and possibly leaving the gate unfastened.
It is an object of the present invention to provide an economical gate closure device of simple construction which may be readily installed with a minimum of labor.
According to the present invention there is provided a closure device which has a rigid lever forming a handle including a pair of substantially parallel legs joined by a bight portion. There are provided first and second post engaging members each loving a pelf ox legs joined by a loop portion, the loop of one member being adapted to receive a stationary post and the loop of the other being adapted to receive the movable post of the stretch gate.
The lever has means defining a first transverse pivot axis for joining the legs of one of the members and means defining a second transverse pivot axis for joining the legs of the other member, the second axis being parallel to the first transverse axis and being located between the first axis and the bight portion of the lever.

cording to one aspect of the invention the first post enraging member is U-shaped and is connected to the means forming the first pivot axis, and the legs of the lever are larger than and are disposed outside of the legs of the first post engaging member. The second post engaging member is also U-shaped and the legs thereof are disposed outside of the legs of the lever. the lever is pivot able from an open position, wherein the second pivot axis is above the plane of the first post engaging member, to a closed position in which the two members and the lever are substantially in a common plane and the second pivot axis is moved to a position disposed between the first pivot axis and the bight of -the first member. Openings are provided in legs of at least one of the members and in the lever, and these openings are positioned to align when the device is in the closed position so that a Loop of an ordinary padlock can be inserted through the aligned openings to lock the device in the closed position, according to another aspect of the invention I one of the post engaging members has its legs joined to the lever by the means definillg the first axis and the others of the post engaging member has the legs thereof joined to the lever by the means defining the other axis, at least one of the members being in the form of a flexible member, such as a length of chain.
In a specific embodiment of this invention the flexible member is formed my a length of chain. Means may be provided to adjust the length of the flexible member, By having one end of the flexible member detachable from the lever, the device can be use as a portable closure c w/
~3~28 mechanism This is useful for use for closing or opening a stretch gate which need not be Provided with its own individual closure but only with a loop of wire which can be moved to or from a gate holding position when the device has been temporarily installed to pull the stretch gate taut.
I've accom~aninq drawing shows embodiments of the present invention as examples, and wherein:
Figure 1 is a perspective view of one embodiment of the device in a locked condition;
Figure 2 is a top view of the embodiment of Figure l; but with the padlock removed, Figure 3 is a perspective view of the embodiment of Figure 1, but in an initial losing position; and Figure 4, which is on the same sheet as Figure 1, shows an alternative embodiment of the present invention.
The reference number 10 generally denotes the closure device of the embodiment of Figures 1 to 3, the device being used to pull a stretch gate 11, which consists of a plurality of strands of barbed wire 12 and a movable post 13, to a closed position in an opening of a fence 14 us best seen in Figure 1, the movable post 13 of the stretch gate is vertical and closely adjacent a stationary post 15 which is normally braced to the next adjacent post 16 at the gate opening of the fence 14.
In the embodiment shown in Figures 1 to 3, the three major components, namely a first post engaging member 18, a second post engaging member 19, and a lever member 20, are all Rudy of strap steel formed into U-shaped ow/
~2~2~
members. It is clear, however, that the members could ye formed of other material such as rod stock or tubular material. Post engaging member I includes a pair of parallel legs 21, 21 joined by a loop or bight portion 22 which is semi-circular in shape for receiving the stationary post 15. At the free ends of the legs 21, 21 aligned openings (not shown) are provided. The lever member 20 includes parallel legs 23, I joined by bight portion 24, the legs 23, 23 being longer than the legs 21, 21~ The legs 23, 23 are disposed outside of legs ] and the outer ends thereof are joined one each to the outer end of legs 1, 21 by rivets 25, 25 passing through each of the openings in legs 21, 21 and openings (not shown) in the outer end of legs 23, 23.
In order to minim interference between legs 21, 21 and legs 23, 23, the radius of bight portion 24 lo slightly larger than the radius of bight portion 22, and the end portions 26, 26 of lets 23, 23 are joined to the main portions of the legs 23, 23 my interned portions 27, 27 (Figure 2).
The rivets 25, 25, which are aligned provide a first transverse pivot axis which allows the lever member 20 to pivot about the axis relative to the post engaging member.
The post engaging member 19 is formed by a pair of parallel legs 29, 29 joined by a semi-circular bight portion 30 defining a post encaging loop or receiving the movable post. The outer ends of the legs 29, 29 have aligned openings (no-t shown), and the Lever member has a second set of aligned opening snot shown) spaced towards bight portion from the first pivot axis. The outer ends of legs of post engaging member 19 are disposed outside of lever member on, and rivet 31, 31, or similar fastening means are ow/ I
aye received in the aligned openings at the outer end of legs 29, 29 and the openings which are intermediate the ends of the legs 23, 23 of the lever member so as to form a second pivot axis parallel to the first and spaced inwardly of the lever member. The second transverse axis allows pivoting of the post engaging member 19 relative to the lever member.
The bight portion 22 of post engaging member 18 is provided with a plurality of bores (not shown) through which nails or screws 32 may be driven into stationary post 15 whereby the gate closure device can be permanently secured to the post lo. One leg 21 of the post engaging member 18 is Provided with a hole 33, one end portion 26 of the lever member 20 is provided with a hole 34, and one leg 29 of post engaging member 19 is provided with hole 35.
Lyon the closure device is in a closed position as shown in Figures 1 and I, wherein all the V shaped members are in a common plane, holes 33, I and 35 align whereby the loop 38 of a padlock 39 (Figure 1) can be passed through the aligrled holes to lock the device in a closed position.
In operation the post 13 of the stretch gate is first pulled to a position adjacent stationary post 15 and the bottom of post 13 is placed within a wire loop a flogger 3) which encircles the bottom of stationary post 15. The loop is of a size to ensure that the bottom strands of the stretch gate are relatively tight when the bottom of post 13 has been inserted into the loop, Toe loop of post 13 is then pulled by hand towards post 15 until post engaging member 19 can be pivoted upward and then lowered over ow/ "I
~;237'~
the upper end of post 13, with the handle or lever member 20 projecting upwardly in an inclined potion over post engaging member 19. The lever member I is then pivoted in the direction of arrow I of figure 3. Thus the pivot axis provided by rivets 31, 31 moves from a position above the plane of the post engaging member 18. As the lever member 20 is pushed down to a position wherein it is in a plane common to post engaging member 18, the second pivot axis, i.e. the axis about which there is relative pivoting between post engaging member 19 and lever member 20, rotates to a position between the first pivot axis, ire.
the axis about which the lever member 20 pivots relative to the post engaging member 18 and the bight portion 22 o-f post engaging member 18. r,~lhen all three members I 19 and 20 are in substantially the same plane, as shown in Figure 1, the loops or bight portions of the two post enqaqinq Myers 18 and 19 have been drawn together so as to pull the top of movable post 13 towards stationary post 15, As was described above, when the device has been moved to its closed position, the padlock 39 can be applied to prevent unauthorized opening of the gate, Unlike some known devices, the connection of the device to the stationary post does not provide the main pivot axis. Because buckwheat 22 simply encircles post 15 and is secured thereto by small nails or screws, the strength of the stationary post is not affected by the attachment of the device to the post.
In the embodiment shown it figure at least one . ; of the post engaging members aye and lea is in the form of a flexible , ow/ ` J

member, -this arrangement being particularly useful when the device aye is used as a portable gate closure mechanism. In this embodiment, the post engaging member aye, which lo connecter -to lever member aye for relative pivoting about the first axis provided by rivets aye, aye, is used to receive the movable post lea. The post engaging member aye, which is in the form of a length of chain a is placed about the stationary post lea One end of the length is connected to the one leg aye of lever member aye by a rivet or other fastening means (not Sheehan A hook 44 is provided on the other leg aye opposite the connection of the one end of the length of chain, which hook is preferably attached to the other leg by a rivet or similar means to allow the hook to rotate relative to the lever member Ida. The hook is of a size and shape to be able to snag any desired link ox the length of chain, The length of chain thus provides a post engaging member of variable length.
In use in closing a gate, the movable post lea lo brought into its initial closing position as previously described. The rigid Yost engaging member aye Jay then be placed about either post aye or aye. Because movable post aye is usually ox a fairly uniform size while stationary post aye may, as an anchor post, be of any size or shape, it would likely be more satisfactory to shape rigid member aye for reception of the usual size for a movable post. The length of chain a is the placed about post lea and pulled tight before being hooked to the lever member aye. The lever member aye is then swung in the direction of arrow aye until the members aye, aye and 20 are in a single plane. At this point a wire loop wish is attached to post aye, can be queue - 8 -75~
lowered over the upper end of post, and the lever raised to permit -the loop 46 to hold the stretch gate taut. The end of this chain can then be unhooked and the device lea removed. The device aye can then be carried for use in opening or closing the next gate.
To open the gate the device lea is reinstalled wit the free end of the length of chain being connected to the hook. Once the lever member boa has been again swung down, the loop 46 can be removed so that when the lo lever member aye is swung up the tension on the stretch gate is released.
In the above described operations, the rivets provide the first axis of pivot and the connections at the opposite ends of the length of chain to legs aye, aye, of lever member aye provide the second transverse axis with the principle of operation being the same as in the previously described embodiment.
It would be possible, of course, to utilize a cable or other flexible member in place ox the length ox chain, but the latter has the advantage of using a relatively simple arrangement for varying the lengths. Further-more, an arrangement is possible wherein both members aye and lea are flexible, these types being preferable where there is a lack of uniformity both in the size of the stationary post and in the movable post at the outer end of the stretch Nate.
As in the embodiment shown in Figures l to 3 it is desirable in the embodiment of Figure 4 to provide in post engaging member aye and lever member aye holes aye and aye, respectively, so that tune device can be locket when tune device is in the closed OW/ IT
position In the embodiment of Figure 4, the lock (not shown) can be passed through holes aye and aye when aligned, and these holes can be positioned so that -the lock will pass through a link of the length of chain 43 as well.
Variations to -the illustrated embodiments will be obvious to those skilled in the art without departing from the spirit of the invention as define in the claims

Figure 2 is a top view of the embodiment of Figure l; but with the padlock removed, Figure 3 is a perspective view of the embodiment of Figure 1, but in an initial losing position; and Figure 4, which is on the same sheet as Figure 1, shows an alternative embodiment of the present invention.
The reference number 10 generally denotes the closure device of the embodiment of Figures 1 to 3, the device being used to pull a stretch gate 11, which consists of a plurality of strands of barbed wire 12 and a movable post 13, to a closed position in an opening of a fence 14 us best seen in Figure 1, the movable post 13 of the stretch gate is vertical and closely adjacent a stationary post 15 which is normally braced to the next adjacent post 16 at the gate opening of the fence 14.
In the embodiment shown in Figures 1 to 3, the three major components, namely a first post engaging member 18, a second post engaging member 19, and a lever member 20, are all Rudy of strap steel formed into U-shaped ow/
~2~2~
members. It is clear, however, that the members could ye formed of other material such as rod stock or tubular material. Post engaging member I includes a pair of parallel legs 21, 21 joined by a loop or bight portion 22 which is semi-circular in shape for receiving the stationary post 15. At the free ends of the legs 21, 21 aligned openings (not shown) are provided. The lever member 20 includes parallel legs 23, I joined by bight portion 24, the legs 23, 23 being longer than the legs 21, 21~ The legs 23, 23 are disposed outside of legs ] and the outer ends thereof are joined one each to the outer end of legs 1, 21 by rivets 25, 25 passing through each of the openings in legs 21, 21 and openings (not shown) in the outer end of legs 23, 23.
In order to minim interference between legs 21, 21 and legs 23, 23, the radius of bight portion 24 lo slightly larger than the radius of bight portion 22, and the end portions 26, 26 of lets 23, 23 are joined to the main portions of the legs 23, 23 my interned portions 27, 27 (Figure 2).
The rivets 25, 25, which are aligned provide a first transverse pivot axis which allows the lever member 20 to pivot about the axis relative to the post engaging member.
The post engaging member 19 is formed by a pair of parallel legs 29, 29 joined by a semi-circular bight portion 30 defining a post encaging loop or receiving the movable post. The outer ends of the legs 29, 29 have aligned openings (no-t shown), and the Lever member has a second set of aligned opening snot shown) spaced towards bight portion from the first pivot axis. The outer ends of legs of post engaging member 19 are disposed outside of lever member on, and rivet 31, 31, or similar fastening means are ow/ I

The rigid Yost engaging member aye Jay then be placed about either post aye or aye. Because movable post aye is usually ox a fairly uniform size while stationary post aye may, as an anchor post, be of any size or shape, it would likely be more satisfactory to shape rigid member aye for reception of the usual size for a movable post. The length of chain a is the placed about post lea and pulled tight before being hooked to the lever member aye. The lever member aye is then swung in the direction of arrow aye until the members aye, aye and 20 are in a single plane. At this point a wire loop wish is attached to post aye, can be queue - 8 -75~
lowered over the upper end of post, and the lever raised to permit -the loop 46 to hold the stretch gate taut. The end of this chain can then be unhooked and the device lea removed. The device aye can then be carried for use in opening or closing the next gate.
To open the gate the device lea is reinstalled wit the free end of the length of chain being connected to the hook. Once the lever member boa has been again swung down, the loop 46 can be removed so that when the lo lever member aye is swung up the tension on the stretch gate is released.
In the above described operations, the rivets provide the first axis of pivot and the connections at the opposite ends of the length of chain to legs aye, aye, of lever member aye provide the second transverse axis with the principle of operation being the same as in the previously described embodiment.
