Abstract
A method and device that allows for streamlined and efficient upright installation of coiled fence materials into fences. The device is an elongated hollow cylindrical drum designed to receive a coil of fence material which may be opened lengthwise according to a set of hinges down one side. A longitudinal gap is provided in the drum through which the leading edge of the coil of fence may pass. The underside of the drum opposite the opening is attached to a sturdy rotatable support pole. The opposite end of the support pole is designed for easy attachment to the lifting mechanism of a suitable machine (such as a tractor, backhoe, forklift or bulldozer). Once the pole is attached to the lifting machine, and a coil of fence placed in the drum, it is closed and latched allowing the leading edge of the fence to extend through the gap in the drum. Using the machine, the method of installation begins with lifting the pole thereby lifting the drum up off the ground. Then the pole and drum are then rotated approximately ninety degrees (90.degree.), bringing the drum to an upright position. The fence coil may then be unrolled as it sits in the drum for attachment to waiting fence posts.

Description
Background of the Invention
The present invention relates to fences, and in particular to a new and highly efficient method and device for the easy upright installation and erection of coiled fences.
Many different kinds of fences are coiled into rolls after manufacturing. These rolls allow for convenient storage and shipment. Chain link and woven wire fabric fence are common examples of fences that are provided in coiled rolls. When a purchaser orders such a fence for installation, and the fence rolls are delivered to the installation site, it is a time consuming, difficult and labor-intensive task to erect the fence upright. This is especially true for taller fences (over 8 feet in height).
Present methods for upright installation of tall coiled fences can involve the use of at least 3 different laborers. The fence coil must be turned on its side, and held upright by at least one laborer. A second laborer stands at the base of the fence as it is unwound, attaching the lower section of the fence (as far as can be reached) to the fence posts. A third laborer stands on a ladder to attach the upper section of the fence (above the reach of the second laborer) to the fence posts. After attachment, the upright fence coil must be unrolled as it is moved to the next fence post for attachment. This alone is a difficult and cumbersome process which will necessarily involve several laborers.
The taller the fence, the wider the fence coil will be, and the more difficult the attachment and movement operations become. Thus, present methods of installing coiled fences involve considerable time, labor and expense.
Summary of the Invention
The present invention overcomes many of the drawbacks presented by present methods of installing coiled fences, and provides a method and device that allows for streamlined and efficient upright fence installation. The device is an elongated hollow cylindrical drum that may be opened lengthwise according to a set of hinges down one side. The drum is designed to receive a coil of fence material. When the drum is closed, a longitudinal gap is provided through which the leading edge of the coil of fence may pass. The longitudinal underside of the drum opposite the opening is attached near the middle using reinforcement to a sturdy rotatable support pole. The opposite end of the support pole is designed for easy attachment to the lifting mechanism of any suitable machine (e.g. tractor, backhoe, forklift or bulldozer).
Once the pole is attached to the lifting machine, a coil of fence is placed in the drum and it is closed and latched. The leading edge of the fence is allowed to extend through the gap in the drum. Using the machine, the method of installation begins with lifting the pole thereby lifting the drum up off the ground. Then the pole is then rotated ninety degrees (90.degree.), rotating the drum to an upright position. This may be done either by hand or using the machine. The machine then drives the elevated, rotated drum into the vicinity of the fence posts where the fence is to be attached. The fence coil is then unrolled as it sits in the drum and is immediately attached to the fence posts. The machine drives the drum from post to post for attachment until the coil runs out. Another coil of fence is then placed in the drum and the process repeated until completed.
It is therefore a primary object of the present invention to provide a device for easy upright installation of coiled fences.
It is a further important object of the present invention to provide a movable, closable drum for receiving and moving a coil of fence material into proper position.
It is a further important object of the present invention to provide a movable, partially closable drum for receiving a coil of fence material having a longitudinal hinged door along one side that provides a longitudinal opening when closed through which one end of a coil of fence material may pass for use in moving coiled fence material into position for erection and installation.
It is a further important object of the present invention to provide a movable, partially closable drum for receiving a coil of fence material to be erected into an upright fence, said drum being attached to one end of a rotatable support pole, the opposite end of the pole being adapted for mounting on a drivable lifting machine such as a tractor.
It is a further object of the present invention to provide a pole mounted closable drum for receiving and holding a coil of fence material which is attachable by a pole means to a drivable lifting machine for easy lifting and placement of the fence coil for upright installation.
It is a further object of the present invention to provide a method for upright installation of coiled fences using a pole mounted closeable drum attached to a drivable lifting machine.
It is a further object of the present invention to provide a method for moving coiled fence material into position for erection and upright installation using a pole mounted partially closeable drum attached to a drivable lifting machine.
It is a further object of the present invention to provide an easy, rapid, and inexpensive device and method for erecting coiled fences utilizing minimal manpower labor.
Additional objects of the invention will be apparent from the detailed descriptions and the claims herein.
