Definitions

the present invention relates to a method of and apparatus for artificially ageing wood.
a shot blast e.g. a sand blast
the purpose of the lacquer is to prevent the scorched effect which particularly remains on the grained parts of the wood rubbing off and in fact dirtying the hands of a user.
the lacquer may take any suitable form, but very good results have been obtained using a matt clear polyurethane lacquer.
the jet or jets may be produced by a burner comprising a combustion chamber in which, in use, a fuel/air mixture is burned in a flash back condition, i.e. in which combustion is complete in the chamber, the flame being always in the chamber, and also having an ignition device at the inlet of the chamber and an outlet nozzle, by which the hot gases produced in the combustion chamber of the mixture issue and can be directed to form said jet or jets.
a burner comprising a combustion chamber in which, in use, a fuel/air mixture is burned in a flash back condition, i.e. in which combustion is complete in the chamber, the flame being always in the chamber, and also having an ignition device at the inlet of the chamber and an outlet nozzle, by which the hot gases produced in the combustion chamber of the mixture issue and can be directed to form said jet or jets.
Such burners usually burn gaseous fuels such as propane, and can produce temperatures of the order of 1100 to 1650°C and the velocity of the jet or jets is of the order of 300 meters per second.
the combustion chamber itself may be similar to that disclosed in British Patent Specification 1556753 but instead of having one row or orifices they are preferably at least two rows of orifices, the orifices of one row being staggered relative to those of the adjacent row or rows.
Such an arrangement can be mounted above the path of the wood which itself can then be passed under the combustion chamber to provide the scorching effect.
the whole effect can be achieved by manually operating the burner, or mounting the burner on a moving trolley or gantry and holding the wood stationary.
a conveyor comprising a plurality of freely rotatable parallel rollers 10 upon which can be mounted several lengths of wood 12 is to be treated.
the wood is caused to be moved over the rollers 10 by means of a drive roller 14 which can be sprung urged downwardly against the upper surface of a length of wood at the upstream (righthand) end of the conveyor 10.
a drive roller 14 which can be sprung urged downwardly against the upper surface of a length of wood at the upstream (righthand) end of the conveyor 10.
the rollers could be driven.
a burner indicated by the general reference numeral 16.
This is a general type disclosed in British Patent Specification 1556753 and includes a combustion chamber 10 and a fuel pipe 20 and an air supply 22.
An ignition device 21 is mounted adjacent the inlet to the combustion chamber and a baffle 23 is provided to deflect the incoming air and gas.
.Two vertically extending guide rails 24 are mounted on each side of the combustion chamber 18 and a support bar is connected at the combustion chamber and can be adjustably positioned on the guide rails so that the actual position of the combustion chamber itself can be vertically adjusted.
the lower part of the combustion chamber is provided with discharge orifices 28 which are arranged in two parallel rows, with the orifices of the rows being staggered relative to one another.
a blasting cabinet 30 Downstream of the burner 16 is a blasting cabinet 30 having front and rear walls 32, 34 provided with a front flap 36 and a rear flap 38 respectively.
the cabinet there are vertical guide rails 40 and a generally horizontally extenomg support bar 42 vertically adjustable on the guide rails, the support bar carrying a number, as shown 4,of vertically extending sand blasters. The horizontal and vertical positions of these sand blasters can be adjusted.
an air jet 46 Located adjacent the rear flap 38 and outside the cabinet 30 is an air jet 46.
a spray cabinet Downstream to this is a spray cabinet having a front wall 50 provided with a flap 52 and vertically adjustable within the spray cabinet is a spray head 54.
the wood is placed, as described above, on the conveyor formed by the rollers 10 and is caused to move to the left.
Gas is combusted into the chamber 18 in a flash back condition i.e. in which combustion is complete in the chamber, the flame being always in the chamber, and a plurality of jets of very hot high speed combustion gases are projected downwardly on the wood.
This has the effect scorching the wood and those parts of the scorched surface which lie between the grain of the wood are blown away by the jet, so that one is left with the grain itself standing out very slightly.
the wood then proceeds into the cabinet 30 in which it issubjected to the action of the blasters which can either blast a relatively soft material such as sand or preferably a harder material such as carborundum or copper slag. This has the effect of blasting away some of the softer parts of the wood also.
the blasters which can either blast a relatively soft material such as sand or preferably a harder material such as carborundum or copper slag. This has the effect of blasting away some of the softer parts of the wood also.
the air jet 46 blows away any residual blasting medium and the latter preferably being recycled in the cabinet 30.
the thus treatedwood then moves into the spray cabinet 46 so it is subjected to the action of a primer lacquer such as matt polyurethane, which replaces the wood resin which has been scorched and blasted out.
a primer lacquer such as matt polyurethane
the lacquer also prevents the scorched effect on the grain and knots from rubbing of and dirtying the hands of a user.
the hot jets and sand blast jets are preferably projected vertically downwardly.
