Abstract
A simple tool that joins mitred wood corners of a picture frame with a minimum effort by eliminating several moving parts that (because of these innovations) are no longer necessary. The use of a Neodymium magnet to direct the action of the v-nails into the wood makes the usual spring load obsolete. The second unique feature of the machine is a food pedal beveled in such a fashion as to bring down the required pressure pad without prior adjustment to suit the moulding height. These improvements provide the user with a tool that will always work as intended without the need for adjustments.
Claims5
A foot operated v-nail machine that uses a NEODYMIUM (rare earth magnet) to draw V-nails into the insertion chamber without spring pressure, eliminating the need for spring load.
The rare earth magnet further assists in aligning v-nails and the hammer (the metal piece that drives the V-nail) so that one v-nail always goes directly into the moulding.
The magazine holds V-nails without the need for a cartridge, accommodating all standard size V-nails without adjustment among different sizes.
The unique design of the foot pedal (featuring a cam-type surface) causes the hold down pressure pad to seek the top of the moulding automatically (regardless of its height) then drive in the V-nail when that contact has been sufficiently made.
