Abstract
Abstract A woodworking machine for endwise joining of oblong wooden members by means of finger joints. The machine includes a magazine for storing of wooden members to be joined, feeding means for successively feeding wooden members from the magazine, a joining station for receiving the wood members, cutting fingers in opposed ends of two wooden members, applying glue to the cut fingers and joining the glued cut fingers in meshing relationship, whereby cutting, glueing and joining of the wooden members are accomplished at the same station in the machine. The machine may further include a cutoff station and an end stop mechanism.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A woodworking machine for endwise joining of oblong wooden members by means of finger joints, said machine comprising: a magazine for side-by-side storing of oblong wooden members to be joined, feeding means for successive longitudinal feeding of the wooden members from said magazine, and a joining station for receiving the wooden members and comprising a single cutter means for simultaneously cutting off fingers in opposed ends of two wooden members to be joined while said wooden members are maintained in the same horizontal plane, means for applying glue to the cut finger ends and means for joining the glued cut fingers in meshing relationship, whereby cutting, glueing and joining of the wooden members are accomplished at the same station in said machine.
Claim 2
Dependent Claim
122 words
A woodworking machine for endwise joining of oblong wooden members by means of finger joints, said machine comprising: a magazine for side-by-side storing of oblong wooden members to be joined, feeding means for successive longitudinal feeding of the wooden members from said magazine, and a joining station for receiving the wooden members and comprising a single cutter means for simultaneously cutting off fingers in opposed ends of two wooden members to be joined while said wooden members are maintained in the same horizontal plane, means for applying glue to the cut finger ends and means for joining the glued cut fingers in meshing relationship, whereby cutting, glueing and joining of the wooden members are accomplished at the same station in said machine.
Claim 3
Dependent Claim
92 words
A woodworking machine according to claim 1, wherein the feeding means comprise a hydraulic power means having a piston rod displaceable parallel to the direction of feed, said piston rod having on its free end a pawl pivotally mounted so as depends from the piston rod into the path of the wooden members to be fed and having a dimension in the direction of feed equal to the distance between the opposed end surfaces of the wooden members to be joined which is required for simultaneously cutting of fingers in said ends.
Claim 4
Dependent Claim
75 words
A woodworking machine according to claim 1 in which said cutter means is mounted on a carriage for displacement in a direction transversely to the direction of feeding, the axis of rotation of said cutter being inclined a small angle with the plane normal to the direction of feed, the sine of said angle being equal to half the finger width divided by the outer diameter of the cutter less the height of the finger.
Claim 5
Dependent Claim
56 words
A woodworking machine according to claim 1 having a cutoff station including an end stop, said end stop being connected with hydraulic power means adapted for temporarily exerting a counterpressure on the forward end of the string of joined wooden members being fed from the joining station, said end stop further being provided with vibration-generating means.
Claim 6
Dependent Claim
26 words
A woodworking machine according to claim 1 wherein the cutting-off station is provided with a cutting-off saw for displacement transversible to the direction of the feed.
