Description

PATENTS FORM NO. 5 PATENTS ACT 1953 COMPLETE SPECIFICATION No.: 203328 Date: 18 February 1983 Complete After Provisional A FASTENING DEVICE I, ROLLAND RICHARD O'HAGAN of 102 Peakes Road, Wanganui, New Zealand, a British subject and New Zealand cititen, hereby declare the invention, for which I pray that a patent may be granted to me and the method by which it i to be performed, to be particularly described in and by the following statement: 2033*8 2 This invention relates to improvements in and relating to fastening devices and particularly but not exclusively to fence stapling devices.

To the present time various proposals have been put forward such as in New Zealand patent specifications No.s: 116821 and 159078, directed towards the stapling of fence wires to fence battens.

However, the above and various other proposals have suffered from various disadvantages particularly in respect of their complexity, and hence cost of manufacturing, or ease of operation.

It is an object of the present invention to provide a fastening device suitable in one embodiment for use as a fence stapling device which overcomes or at least obviate disadvantages of such devices available at the present time.

Accordingly, in one embodiment of the present invention, there is thus provided a fence stapling device, comprising:- (a) an arm having a substantially hook—shaped end portion engageable behind a fence batten on one side thereof; (b) -a staple locating »eans to accouiodate a staple therein; (c) a staple ejecting Beans movable into said staple locating Beans to eject said staple and force it about a wire passing on an opposite side of said batten; (d) a lever means movable between a first 203338 position to withdraw 6aid staple ejecting means from said staple locating means and to enable a staple to be loaded into said staple locating means and a second position to move said staple ejecting means into said staple locating means.

Accordingly in a further embodiment of the invention a fastening device is provided comprising (a) an arm having a substantially hook-shaped end portion engageable behind a fence batten on one side thereof; (b) % staple locating Beans to accommodate a staple therein; (c) a staple ejecting means movable into said staple locating means to eject 6aid staple and force it about a wire passing on an opposite side of said batten; (d) a lever means movable between a first position to withdraw said staple ejecting means from said staple locating means and to enable a staple to be loaded into said staple locating means and a second position to move said staple ejecting means into said staple locating means.

The invention will now be described by way of example of various embodiments and with reference to the accompanying drawings wherein: |\ FIGURE 1 : shows diagramatically a side-view of a fence stapling device in use and according to one embodiment of the invention; FIGURE 2 : shows the fence stapling device of Figure 1 with part of its body portion removed to show its interior ? FIGURE 3 : shows very diagramatically a part cross-sectional plan view of the device of Figure 1; FIGURE 4 : shows diagramatically a view from underneath of the fence stapling 10 device of Figure 1; FIGURE 5 : shows very diagramatically an exploded view of the staple cartridge of the preceding Figures; FIGURE 6 : shows very diagramatically a side .15 perspective view of the fence stapling device of the preceding Figures; FIGURE 7 : shows diagramatically a part cross-sectional side view of the 20 fence stapling device of another embodiment of the invention.

Referring to Figures 1 to 6 of the accompanying drawings a fence stapling device is referenced generally by arrow 1.

It is shown having a body portion 2 having a pair of handles 4 and 24 associated therewith, a lower handle 4 suitably being secured with or formed as part of the body portion 2. The upper handle 24 is however shown pivotally connected by means of bolt or pin 3 with the body portion 2. The bolt or pin 3 extends through a pair of spaced apart body plate portions 21 forming a gap 20 therebetween within which the pivoted end of the handle 24 can travel as shown by arrows A-A in Figure 2. A nut 32 (see Figure 6) is shown secured with a threaded end of the bolt or pin 3. Hand grips or enlarged portions 5 are shown provided on the outer ends of the handles 4 and 24 to facilitate the gripping of the handles by an operator. The side plate portions 21 of the body portion 2 are shown extending inwardly so as to form side body portions 33 disposed above which is shown a channel shaped portion 6. A pin or bolt 7 is shown extending through the channel portion 6 and through a sleeve 31 so as to secure one end of an arm 11 within the channel 6.

The arm 11 is shown having a substantially hook-shaped end portion with a downwardly depending portion 30 extending to a transverse tip portion 12.

As shown in Figure 1, the hook-shape of the arm 11 is adapted to be positionable behind a fencing batten of post 13 during a stapling operation.

Positioned at a front end of the body portion 2 is shown a support member 22 which is intended to abut the fence batten or post 13 on the opposite side from the hook 11 during a stapling operation.

Extending transversly of the body portion 2 at a front end thereof is shown a cartridge holder 10. The holder 10 is shown provided with an inwardly directed groove 19 which is adapted to releasably engage about a recessed portion 23 of a cartridge member 8. The cartridge member 8 is substantially hollow and has a spring 17 accommodated therein. A bar 15 associated with the holder 10 can accommodate a plurality of the substantially U-shaped staples 18. A collar 16 also mountable over the bar 15 will in use be biased by the spring 17 against the top most staple so as to suitably dispense only a single staple 18 into a staple locating space defined for this purpose between the side body portions 33 and in front of a staple pusher member 9.

The pusher member 9 is in the form of a bar having a front edge with a groove therein adapted to accommodate the closed end of a staple 18. At its other end the bar 9 is shown connected by means of a pin or bolt 28 with a pair of spaced apart link arms 27 (see Figure 3 particularly). The opposite end of the link arms 27 are shown connected by means of a pin or bolt 26 with a bifurcated end 25 of the movable handle 24.

It will be seen that movement of the handle 24 in a direction indicated by arrows A will result in the handle end 25 moving in a direction indicated by arrows B this having the effect of pulling and pushing the bar 9 by means of the link arms 27. Accordingly by raising the handle 24 a single staple 18 can be discharged into the space in front of the pusher bar 9. Downward movement of the handle 24 will then cause the pusher bar 9 to engage the staple 18 and drive it into the fence batten 13 to hold the fence wire 14 in place.

With the number of staples being limited only by the size of the cartridge 8, a large number of stapling operations can be carried out both speedily and effectively until the cartridge 8 is empty and a replacement set of staples needs to be loaded.

The fence stapler 1 may suitably be of a light metal, suitably galvanised or stainless steel, or rigid plastics or a combination of both materials. It will be appreciated, however, that any suitable materials can be used in the construction of the stapler 1 and that it can be manufactured by any suitable technique.

Referring now to Figure 7 of the accompanying drawings, reference numerals corresponding to those used in respect of the preceding Figures will again be used where appropriate.

Thus, the device referenced generally by arrow 1A is shown with; a hook 11 having a free end 12; a body portion 2; a movable handle 24 and a fixed handle 4; movement of a pusher bar 9 causing the corresponding movement of a staple 18. The movement of the pusher bar 9 is again effected by means of movement of the movable handle 24 pivoted on a pin or bolt 3 relative to the body portion 2. The pusher bar 9 is however in this embodiment shown including an enlarged end portion 40 accommodated within the body portion 2 and in which a roller member 41 secured with, or provided on, the handle 24 is able to travel.

Thus, as the handle 24 is moved in a direction indicated by arrows A-A, the roller 41 will move within the aperture in the portion 40 between the full and dotted positions shown. In so doing the pusher bar 9 will be operated so as to engage with a staple 18 and to open the staple locating space so that a fresh staple can be introduced.

Although in the aforegoing description reference has been made to the use of a cartridge providing a plurality of staples 18, a single staple device in which a single staple is loaded manually for each stapling operation could alternatively by employed.

Additionally, while reference has been made throughout the specification and claims to a "fence stapling device" and to a "staple" it is to be understood that for the purposes of this specification these terms respectively include all other types of fastening devices and fasteners or nails. For example, the device could be used, with appropriate modification if necessary, to apply fasteners by farriers in fixing horse shoes, by surgeons in pinning broken bones or by builders in splicing framing timber.

Moreover, while specific components or integers have been described it is to be appreciated that known equivalents could be utilised although these have not been specifically described.

Furthermore, although this invention has been described by way of example and with reference to preferred embodiments thereof it is to be understood that modifications or improvements may be made thereto without departing from the scope or spirit of the invention.
