Abstract
This invention relates to manually operating tool for removal of gang-nail plates from wood members used to manufacture floor and roof trusses. The tool is comprised of a handle (2) which has a lower notched chisel jaw (1), upper grab teeth (7), and a cam lift (8) attached to the base end of the handle (2). The opposite end of the handle (2), is designed to be struck with a hammer so that force can be applied to lower notched chisel jaw (1) for penetration under the edge of a gang-nail plate in an open position. A jaw clamp lever (3) applies upper grab teeth (7) to protrude into the gang-nail plate in the closed position. Applying down pressure to handle causes rotation of the lower notched chisel jaw (1) and upper grab teeth (7) about the cam lift (8) to extract and remove the gang-nail plate from the wood surface.
Description
GANG-NAIL EXTRACTOR
FIELD OF INVENTION
This invention relates to manually operating tool for removal of gang-nail plates from wood members used to manufacture floor and roof trusses.
BACKGROUND ART
During the manufacturing process of floor and roof trusses, it may be necessary to remove gang-nail plates. To date, removal of gang-nail plates is done by method of hammer and chisel or using a type of crowbar. Either method results in splintering of the wood members and total destruction of the gang-nail plate. This application is time consuming and costly. Not only are the gang-nail plates not reusable, the lumber members result in large pieces of wood gouged from them, making them no longer usable.
SUMMARY OF THE INVENTION
It is an aspect of this invention to provide a tool that is much more efficient in removing and dislodging gang-nail plates from wood members in a matter of seconds.
In accordance with the present invention there is provided a tool having a handle with a base end and a striking end, a lower notched chisel jaw is attached to the base end of said handle, an upper grab teeth is pivotally attached to the base end of said handle for rotational movement of said lower notched chisel jaw from an open position to a closed position. A
pressure lever is attached to said upper grab teeth and said handle, and a cam lift is attached to the base end of said handle opposite said lower notched chisel jaw.
By forcing said lower notched chisel jaw under the gang-nail plate by a force applied to the striking end of said handle, the pressure lever is activated to move the lower notched chisel jaw from an open position to a closed position to allow said upper grab teeth to protrude down through the gang-nail plate. A downward pressure is applied manually to said handle causing a pivoting I
motion about said cam lift to cause a lifting and extraction of the gang-nail plate from the lumber member.
Preferably, the lower notched chisel jaw having slots to allow said upper grab teeth to protrude down through openings of the gang-plates. A tie rod is connected to the base of said jaw clamp lever at an upper end and connected to the upper grab teeth at a lower end of tie rod. In a preferred embodiment, the tie rod is guided through a tie rod guide.
It is a further aspect of this invention to provide a method for removal of a gang-nail plate from floor and/or truss lumber members comprising the steps of aligning said lower notched chisel jaw with said gang-nail plate; striking the striking end of the handle with a hammer so that a force can be applied to said lower notched chisel jaw for penetration under said gang-nail plate; applying pressure on said pressure lever to move said upper grab teeth from an open position to a closed position for allowing said upper grab teeth to protrude down through the gang-nail plate; and applying a downward pressure to said handle causing a pivoting motion about said cam lift to cause a lifting and extraction of the gang-nail plate from the lumber member.
Once the gang-nail plate has been removed from the lumber member, said lever handle is applied to said open position causing said grab teeth to release said gang-nail plate from said notched chisel jaw and said upper grab teeth. This method is safer and requires no electricity.

BRIEF DESCRIPTION OF THE FIGURES IN THE DRA WINGS
Referring now to the drawings which form a part of this disclosure:
Figure 1 is an elevation drawn to illustrate total embodiment of the invention in an open position.
Figure 2 is an elevation drawn to illustrate total embodiment of the invention in a closed position.

DESCRIPTION OF THE PREFERRED EMBODIlyiENT OF THE IWVENTION
In drawings, which illustrate embodiments of the invention, Figure 1 is a full view elevation of Gang-Nail Extractor in the open position. Figure 2 is a full view of Gang-Nail Extractor in the closed position.
The tool illustrated in Figure 1, is comprised of a handle (2), which has a lower notched chisel jaw (1) connected to the base of the handle (2). The opposite end of the handle (2), is designed to be struck with a hammer so that force can be applied to lower notched chisel jaw (1) for penetration under the edge of a gang-nail plate.
During this action, a jaw clamp lever (3) is in the open position. Once the lower notched chisel jaw (,t) is in position under edge of gang-nail plate, the jaw clamp lever (3) is then moved to a closed position by pivoting about ajaw clamp lever pivot (4).
With this action, a tie rod (5), which is connected to the base of jaw clamp lever (3), is guided through a tie rod guide (6). At the lower end of the tie rod (5), upper grab teeth (7) are connected.
With jaw clamp lever (3) in closed position, this applies upper grab teeth (7) to protrude through hole or holes in the gang-nail plate.
Applying down pressure to handle causes pressure on a cam lift (8) which causes rotation of the lower notched chisel jaw (1) and upper grab teeth (7) about the cam lift (8) so as to extract and remove the gang-nail plate from the wood surface. To release the gang-nail plate from the upper grab teeth (7) and the lower notched chisel jaw (1), the jaw clamp lever handle (3) is placed in the open position.
DESCRIPTION OF THE PREFERRED EMBODIlyiENT OF THE IWVENTION
In drawings, which illustrate embodiments of the invention, Figure 1 is a full view elevation of Gang-Nail Extractor in the open position. Figure 2 is a full view of Gang-Nail Extractor in the closed position.
The tool illustrated in Figure 1, is comprised of a handle (2), which has a lower notched chisel jaw (1) connected to the base of the handle (2). The opposite end of the handle (2), is designed to be struck with a hammer so that force can be applied to lower notched chisel jaw (1) for penetration under the edge of a gang-nail plate.
During this action, a jaw clamp lever (3) is in the open position. Once the lower notched chisel jaw (,t) is in position under edge of gang-nail plate, the jaw clamp lever (3) is then moved to a closed position by pivoting about ajaw clamp lever pivot (4).
With this action, a tie rod (5), which is connected to the base of jaw clamp lever (3), is guided through a tie rod guide (6). At the lower end of the tie rod (5), upper grab teeth (7) are connected.
With jaw clamp lever (3) in closed position, this applies upper grab teeth (7) to protrude through hole or holes in the gang-nail plate.
Applying down pressure to handle causes pressure on a cam lift (8) which causes rotation of the lower notched chisel jaw (1) and upper grab teeth (7) about the cam lift (8) so as to extract and remove the gang-nail plate from the wood surface. To release the gang-nail plate from the upper grab teeth (7) and the lower notched chisel jaw (1), the jaw clamp lever handle (3) is placed in the open position.
