Abstract

A clamp for holding boards of wood adjacent other boards of wood for nailing, such as in a floor frame is described. The clamp generally includes an elongated body having a lever to open and close a fixed jaw and moveable jaw that are also connected to the body. An arm is connected to the body and to the lever. The jaws generally include teeth to sink into a surface of the wood to secure the wood within the jaws. An end piece includes lips to prevent unwanted movement of the wood as it is held within the jaws. The clamp further includes a tongue that is adapted to overhang other pieces of wood to which ht he board of wood is to be nailed.

Claims

1. A clamping apparatus, comprising:

an elongated body having a first end and a second end, wherein the first end is a tongue;

an end piece having two lips generally perpendicular to the body and being connected to the second end of the body;

a fixed jaw connected to the body adjacent the tongue;

a moveable jaw connected to the body; and

an arm having a first end and a second end, the first end being connected to the body adjacent the end piece and the second end of the arm being connected to a lever, wherein the lever is further connected to the moveable jaw.

2. The apparatus as claimed in claim 1 wherein the fixed jaw is connected to the body through a connection plate that is generally perpendicular to the fixed jaw.

3. The apparatus as claimed in claim 1 wherein the moveable jaw is pivotally connected to the body through a moveable jaw arm that is pivotally connected to the lever.

4. The apparatus as claimed in claim 3 wherein the lever comprises:

a main lever portion having a first end and a second end;

a short end lever portion connected generally perpendicular to the first end of the main lever portion;

a lever pivotal portion connected to the second end of the main lever portion, wherein the lever pivotal portion is pivotally connected to the second end of the arm and is pivotally connected to the moveable jaw arm.

5. The apparatus as claimed in claim 1 wherein the fixed jaw and the moveable jaw further comprise one or more teeth.

6. The apparatus as claimed in claim 1 wherein the first end of the arm is pivotally connected to the body.

7. The apparatus as claimed in claim 1 wherein the clamp can be in an open position and in a closed position.

8. The apparatus as claimed in claim 7 wherein the fixed jaw and the moveable jaw are in opposition and generally parallel when the clamp is in the closed position.

9. An apparatus for clamping a board of wood for placement

adjacent a second board of wood, comprising:

an elongated body;

jaws connected to the body, the jaws being adapted to clamp and hold the board of wood;

an end piece connected to the body and adapted to prevent unwanted motion of the board of wood when the board of wood is connected and disconnected from the apparatus; and

a lever connected to the body through an arm and to one of the jaws, the lever being adapted to open and close the jaws to place and remove the board of wood from the apparatus.

10. The apparatus as claimed in claim 9 further comprising a tongue adjacent the jaws.

11. The apparatus as claimed in claim 10 wherein the jaws comprise leading edges that are adapted to align and be flush with an end of the board of wood.

12. The apparatus as claimed in claim 11 wherein the leading edges and the end of the board of wood are adapted to be positioned against a surface of the second board of wood and wherein the tongue is adapted to rest upon an upper edge of the second board of wood.

13. The apparatus as claimed in claim 9 wherein the jaws further include teeth to penetrate a surface of the board of wood while the board is held within the jaws.

14. The apparatus as claimed in claim 9 wherein the elongated body generally contacts the board of wood along the entire length of the body and wherein the tongue overhangs off a leading edge of the board of wood.
