Adjustable guide tool aligns and positions stacks of material for cutting at various angles. The device adapts its shape to stacks of any corner angle, adjusts to any cutting angle, and quickly aligns the stacks for repeated cutting. With this device, an operator need not place his hands under the knife during alignment

Adjustable Cutting Guide Aligns and Positions Stacks of Material 
The problem: 
To provide a fixture which accurately aligns and 
positions stacks of material for cutting at various 
angles. Previous guide tools were not always capable 
of both aligning and positioning materials, partic-
ularly those having corner angles other than 901 
Further, while aligned cuts may have been made on 
individual stacks of materials, the cutting angle was 
often lost when a series of stacks was cut.
The solution: 
An adjustable aligning and positioning device that 
adapts its shape to stacks of any corner angle, ad-
justs to any cutting angle, and quickly aligns the stacks 
for repeated cutting. 
How it's done: 
Two guide arms adjust to the corner angle of the 
material by the pivoting of arm I within the socket of 
arm 2. A threaded pin, extending through both arms 
(continued overleaI(

at their joint, tightens to lock the two at the desired 
angle. Two plates, extensions of arm 2, encompass a 
circular base in a sandwich arrangement, connecting 
to it by a pin. A backstop is bolted tangentially to the 
base. The arms, locked to form a particular angle, 
may be rotated as a unit about the pin through the 
base, allowing various cutting angles with reference to 
the backstop. A locking pin is inserted through align-
ing holes in the plates and base to lock the device at 
the cutting angle. The backstop is placed against a 
mating stop on the machine to complete positioning. 
Notes: 
1. Cutting angles available from this fixture are de-
termined by the position and number of the locking 
holes in the base. 
2. With this device, an operator need not place his 
hands under the knife during alignment.
3. The device could be used in the paper, printing, or 
textile industries where materials of various shapes 
are cut.
