Abstract

Abstract A continuous apparatus for cutting workpieces at different angles including a conveyor with flights thereon which deliver a plurality of workpieces in side-by-side relation to a cutting station, clamping means which engage the workpieces while advancing into the cutting station to hold the same against vertical displacement, and a pair of rotary power saws disposed in sequence in the cutting station with their blades in different angular planes for sequentially cutting the workpieces at different angles. Safety means are provided to enclose the chain and the power saws, with adjustment means being provided in front of the guards to permit angular adjustment of the axis of the power saws from a location remote from the saws.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 129 words
A coNtinuous apparatus for cutting workpieces at different angles which comprises a conveyor means, a plurality of flights on said conveyor means for delivering a plurality of workpieces in side-by-side relation to a clamping means station, clamping means engageable by said plurality of workpieces while advancing into said cutting station to hold said workpieces in clamped relation, said clamping means including a pair of bars pivotally mounted at one end and having spring means at the opposite end applying a downward pressure on the workpieces in said cutting station, and a pair of rotary power saws disposed in sequence in said cutting station with their blades in different angular planes for sequentially cutting said workpiece at said different angular planes for sequentially cutting said workpiece at said different angles.
Claim 2
Dependent Claim 129 words
A coNtinuous apparatus for cutting workpieces at different angles which comprises a conveyor means, a plurality of flights on said conveyor means for delivering a plurality of workpieces in side-by-side relation to a clamping means station, clamping means engageable by said plurality of workpieces while advancing into said cutting station to hold said workpieces in clamped relation, said clamping means including a pair of bars pivotally mounted at one end and having spring means at the opposite end applying a downward pressure on the workpieces in said cutting station, and a pair of rotary power saws disposed in sequence in said cutting station with their blades in different angular planes for sequentially cutting said workpiece at said different angular planes for sequentially cutting said workpiece at said different angles.
Claim 3
Dependent Claim 27 words
The apparatus of claim 1 which includes adjustment means for adjusting the angular axis of each of said saws from positions remote from each of said saws.
Claim 4
Dependent Claim 32 words
The apparatus of claim 2 in which said conveyor means consists of a continuous chain, and includes a guard positioned forwardly of said chain, said adjustment means extending forwardly of said guard.
Claim 5
Dependent Claim 25 words
The apparatus of claim 3 in which said adjustment means includes a crank which upon rotation pivots the power saw with respect to its support.
