Claim 1
Independent Claim
259 words
A finger jointing machine comprising, in combination: (a) a horizontal support table; (b) a vertical guide fence adjacent said support table; (c) means for moving timber along said support table; (d) means for clamping two pieces of timber on said support table and against said guide fence, with the rear end of one piece of timber spaced from the front end of the other piece of timber; (e) a cutting and gluing unit movable vertically through the space between the ends of the timber clamped by said clamping means, said cutting and gluing unit including: (i) two rotatable cutters rotatable about horizontal axes, each cutter having axially spaced teeth, the teeth of one cutter being axially spaced from those of the other by half the spacing between the teeth of each cutter; (ii) means to rotate the cutters in opposite directions, whereby the teeth of one cutter engaging the rear end of said one piece of timber and the teeth of the other cutter engage the front end of said other piece of timber are both moving upwardly; and (iii) two ribbed gluing rollers arranged one below each of said cutters, the ribs of said gluing rollers being disposed directly below the teeth of the cutter thereabove; and (f) means to move said cutting and gluing unit vertically upwardly past the rear end of said one piece of timber and the forward end of said other piece of timber, whereby when said pieces of timber are clamped by said clamping means, said unit cuts and glues interfitting fingers therein.

A finger jointing machine comprising, in combination: (a) a horizontal support table; (b) a vertical guide fence adjacent said support table; (c) means for moving timber along said support table; (d) means for clamping two pieces of timber on said support table and against said guide fence, with the rear end of one piece of timber spaced from the front end of the other piece of timber; (e) a cutting and gluing unit movable vertically through the space between the ends of the timber clamped by said clamping means, said cutting and gluing unit including: (i) two rotatable cutters rotatable about horizontal axes, each cutter having axially spaced teeth, the teeth of one cutter being axially spaced from those of the other by half the spacing between the teeth of each cutter; (ii) means to rotate the cutters in opposite directions, whereby the teeth of one cutter engaging the rear end of said one piece of timber and the teeth of the other cutter engage the front end of said other piece of timber are both moving upwardly; and (iii) two ribbed gluing rollers arranged one below each of said cutters, the ribs of said gluing rollers being disposed directly below the teeth of the cutter thereabove; and (f) means to move said cutting and gluing unit vertically upwardly past the rear end of said one piece of timber and the forward end of said other piece of timber, whereby when said pieces of timber are clamped by said clamping means, said unit cuts and glues interfitting fingers therein.
Claim 3
Dependent Claim
66 words
A finger jointing machine as claimed in claim 1, and further comprising means to rotate said two ribbed gluing rollers in opposite directions, whereby the portions of the ribs of one roller engaging the rear end of said one piece of timber and the portions of the ribs of the other roller engaging the front end of said other piece of timber are both moving downwardly.
Claim 4
Dependent Claim
48 words
A finger joining machine as claimed in claim 1, and further comprising a glue tank arranged below said cutting and gluing unit and a glue pick-up roller rotatable in said tank for engagement by said gluing rollers when the cutting and gluing unit is at its lowermost position.
Claim 5
Dependent Claim
49 words
A finger jointing machine as claimed in claim 1, and further comprising support members mounted on said clamping means at a position to engage the timber above the portions thereof adjacent the spaced ends, and fingers on said support members disposed to overlie the fingers formed by the cutters.
Claim 6
Dependent Claim
37 words
A finger jointing machine as claimed in claim 4, and further comprising means to move said support members away from the path of movement of the gluing rollers after the cutters have moved past the support members.
Claim 7
Dependent Claim
50 words
A finger jointing machine as claimed in claim 5, and further comprising pivots holding said support members and means to pivot said support members from a substantially horizontal position in which they engage the timber to a substantially vertical position in which they are out of engagement with the timber.
Claim 8
Dependent Claim
37 words
A finger jointing machine as claimed in claim 1, in which said cutting and gluing unit includes abutments arranged above said cutters effective to define the spacing between the ends of the timber before they are clamped.
