Joiner

1. A joiner for assembling tongue and groove planks, the joiner comprising:

a link interconnecting a ram and a motorized hammer via a rotatable joint;

the rotatable joint including a shaft and a body;

the rotatable joint configured to transfer axial motion therethrough;

the rotatable joint configured to allow rotation of the shaft while avoiding rotation of the body;

the link including a tang and a shank;

a free end of the shank fixed in a chuck of the motorized hammer;

a rounded end of the tang with a center hole, the rounded end seated in a rounded V slot of the ram;

the tang rotatably fixed in the rounded V slot by a clevis pin passing through the rounded V slot and through the center hole in the tang;

the ram including a block, a handle centrally located atop the block, and plural thumb screws;

the block having an upper portion and a lower portion, the upper portion overhanging the lower portion so as to create a void along a first edge of the block for receiving a tongue of a tongue and groove plank; and,

the thumb screws for passing through respective corners of the block for supporting the block at adjustable elevations.

2. The joiner of claim 1 wherein the shank includes one bend and a tang central axis intersects with a shank portion central axis at an angle of about 20 to 45 degrees.

3. The joiner of claim 1 wherein the link includes two bends and a tang central axis is parallel to the central axis of the shank portion extending from the chuck of the motorized hammer.

4. The joiner of claim 1 wherein the motorized hammer is a rotary hammer and the link includes first and second shank portions interengaged via a coupling that transmits hammer blows but that does not transmit rotation.

5. The joiner of claim 1 further including:

a sled;

a top side of the sled for engaging portions of the thumb screws that pass through the block;

a bottom side of the sled for resting upon and smoothly passing over a plank underlayment; and,

the sled and screw engagements for allowing rotation of the screws without rotating the sled.

6. A joiner for assembling tongue and groove planks, the joiner comprising:

a link interconnecting a ram and a motorized rotary hammer via a rotatable joint;

the rotatable joint including a shaft and a body;

the rotatable joint configured to transfer axial motion therethrough;

the rotatable joint configured to allow rotation of the shaft while avoiding rotation of the body;

the link including a tang and a shank;

first and second shank portions interengaged via a rotary coupling for preventing transmission of rotary motion from the motorized rotary hammer to the ram;

a free end of the shank for fixation in a chuck of the motorized rotary hammer;

a rounded end of the tang with a center hole, the rounded end seated in a rounded V slot of the ram;

the tang for rotatable fixation in the rounded V slot by a clevis pin passing through the rounded V slot and through the center hole in the tang;

the ram including a block, a handle centrally located atop the block, and thumb screws at corners of the block;

the block having an upper portion and a lower portion, the upper portion overhanging the lower portion so as to create a void along a first edge of the block for receiving a tongue of a tongue and groove plank; and,

the thumb screws for passing through respective corners of the block for supporting the block at adjustable elevations.

7. The joiner of claim 6 further comprising:

a variable power control within the motorized rotary hammer for selectively controlling energy delivered by the hammer.

8. The joiner of claim 7 wherein:

a pressure exerted by the block on the plank does not exceed fifty percent of a plank compressive strength at a block and plank interface.
