Abstract
Abstract The disclosure relates to a fencing device in which a transport moves along the line of fencing and feeds the wires which are to form the line of fencing under tension once fencing is commenced. The posts are positioned by driving means along the line of strip wire and the wires are tied to the posts while the tension is maintained. The tension is maintained by braking means either on a drum which carries the wire or on separate means over which the wire passes and the tension means are so arranged that the force on this tension drum or means is measured by springs so arranged that the brakes are applied until the required tension is reached whereupon the brakes are progressively released to maintain the tension, control being such that the tension is maintained whether the vehicle moves forwardly during the playing out of the wire or is stationary during the driving of the posts.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
240 words
A portable fencing device comprising transport means, wire carrying means on the transport and tensioning means on the transport to feed wires from the carrying means, and post driving means on the said transport rearwardly of the wire feed means whereby posts can be driven into the ground at the tensioned line of the said wires and fixed to a post while maintaining the tension, said tensioning means comprising a tension drum to engage the wire, brake means on the drum, a mount attached to a front portion of said transport for the said drum and movable in relation to the said transport, means to apply the brake to the drum when no tension exists on the wires, and means to release the brake in proportion to applied tension to maintain a predetermined tension on the wire when established by movement of the transport along the line of fencing; the tension determining means comprising said mount including a fixed frame on the transport, and a movable frame supported on the fixed frame carrying the said drum; brake operating means between the fixed frame and the movable frame, spring means to urge the movable frame into a determined position in relation to the fixed frame, and spring means to cause the brake to be applied when the movable frame is in the said determined position but to release the brake on movement of the movable frame against the applied spring tension.
Claim 2
Dependent Claim
240 words
A portable fencing device comprising transport means, wire carrying means on the transport and tensioning means on the transport to feed wires from the carrying means, and post driving means on the said transport rearwardly of the wire feed means whereby posts can be driven into the ground at the tensioned line of the said wires and fixed to a post while maintaining the tension, said tensioning means comprising a tension drum to engage the wire, brake means on the drum, a mount attached to a front portion of said transport for the said drum and movable in relation to the said transport, means to apply the brake to the drum when no tension exists on the wires, and means to release the brake in proportion to applied tension to maintain a predetermined tension on the wire when established by movement of the transport along the line of fencing; the tension determining means comprising said mount including a fixed frame on the transport, and a movable frame supported on the fixed frame carrying the said drum; brake operating means between the fixed frame and the movable frame, spring means to urge the movable frame into a determined position in relation to the fixed frame, and spring means to cause the brake to be applied when the movable frame is in the said determined position but to release the brake on movement of the movable frame against the applied spring tension.
Claim 3
Dependent Claim
126 words
A portable fencing device according to claim 1 characterized in that the tension determining means comprise a fixed frame on the transport, a movable frame supported on the fixed frame and carrying the said tensioning drum, spring means to urge the movable frame into a determined position in relation to the fixed frame, brake operating means supported on the fixed frame, and brake controlling springs between the movable frame and the brake operating means to urge the brake operating means to brake-engaging position when the movable frame is in the said determined position but to decrease tension on the brake controlling springs when the movable frame is moved by wire tension on the drum against the tension of the springs between the fixed and movable frames.
Claim 4
Dependent Claim
15 words
A portable fencing device according to claim 9 wherein the brake operating means are hydraulic.
Claim 5
Dependent Claim
49 words
A portable fencing device according to claim 1 characterized in that the post driving means comprise means to engage and drive the posts, and means to effect movement of the driving means laterally to the line of fencing to allow the driving means to be brought into fence alignment.
Claim 6
Dependent Claim
38 words
Improvements according to claim 1 where said wire feed means position the wires along the fence line in desired vertical relation and the tension on the wires retains them in position as the posts are driven into position.
Claim 7
Dependent Claim
155 words
An improved fencing device, comprising: a transport; a supply of fencing wire carried by the transport; a wire tensioning drum carried by the transport and engaging the fencing wire to continuously maintain tension on the fencing wire as the wire is run out from the transport; and tension determining means including a brake engaging the drum to regulate the amount of tension of the wire, the tension determining means further comprising a fixed frame on the transport, a movable frame supported on the fixed frame and carrying the said drum, brake operating means between the fixed frame and the movable frame, spring means to urge the movable frame into a determined position in relation to the fixed frame, and second spring means to cause the brake to be applied when the movable frame is in the said determined position but to release the brake on movement of the movable frame against the applied spring tension.
Claim 8
Dependent Claim
155 words
An improved fencing device, comprising: a transport; a supply of fencing wire carried by the transport; a wire tensioning drum carried by the transport and engaging the fencing wire to continuously maintain tension on the fencing wire as the wire is run out from the transport; and tension determining means including a brake engaging the drum to regulate the amount of tension of the wire, the tension determining means further comprising a fixed frame on the transport, a movable frame supported on the fixed frame and carrying the said drum, brake operating means between the fixed frame and the movable frame, spring means to urge the movable frame into a determined position in relation to the fixed frame, and second spring means to cause the brake to be applied when the movable frame is in the said determined position but to release the brake on movement of the movable frame against the applied spring tension.
Claim 9
Dependent Claim
59 words
The improved fencing device according to claim 6 wherein the tensioning drum is provided with a plurality of wire engaging members projecting outwardly from the drum in an irregularly spaced relationship whereby the wire is wrapped around the drum and linked by the wire engaging members to provide the necessary grip on the wire to maintain the desired tension.
Claim 10
Dependent Claim
22 words
The improved fencing device according to claim 6 wherein the wire tensioning drum is adapted to contain a roll of wire fabric.
Claim 11
Dependent Claim
50 words
The improved fencing device according to claim 6 wherein the tensioning drum is carried by the movable frame which is slidable on the transport, the device further including said second spring means which are spring control means engaging the frame and the transport and operable to control the brake means.
