Abstract
An auxiliary appliance, known as a mitering device, for setting the cutting angle in miter-cutting operations prior to the cutting proper, comprising two arms (1, 2), which are pivotally interconnected by means of a hinge, each one of said arms having at least one orientation face, and an angle-indicating means (4), which is connected to the arm-interconnection hinge via a gear mechanism (5), said gear mechanism being adapted, upon relative pivotal motion of the arms, to transfer essentially half of said pivotal motion to the angle-indicating means relative to the arms.

An auxiliary appliance, known as a mitring device, for setting the cutting angle in mitre-cutting operations prior to the cutting proper, comprising two arms (1,2), which are pivotally interconnected by means of a hinge, each one of said arms having at least one orientation face, and an angle-indicating means (4), which is connected to the arm-interconnecting hinge via a gear mechanism (5), said gear mechanism being adapted, upon relative pivotal motion of the arms, to transfer essentially half of said pivotal motion to the angle-indicating means relative to the arms, characterised in that said gear mechanism comprises a first part (6), which is stationarily arranged on a first one of the arms, and a second part (7), which is movably arranged on the second one of said arms and meshes with the first part, the angle-indicating means (4) being securely joined to the second part and extending in a plane being essentially perpendicular to the pivotal plane of the arms.
An auxiliary appliance as claimed in any one of the preceding claims, wherein the arms are formed with two orientation faces each, said faces being parallel with one another.
An auxiliary appliance as claimed in any one of the preceding claims, wherein said gear mechanism parts comprise toothed members.
An auxiliary appliance as claimed in any one of the preceding claims, wherein it further comprises locking means to lock the arms in the desired relative position.
