Abstract

Disclosed is a clamping device that is useful in holding material in place while it is having a manufacturing process performed on it. It is particularly useful in holding fragile or brittle material which is subject to marring or breaking, such as a thin sheet of copper or glass. (Image Omitted)

Non-Marring Pneumatic Clamp

      Disclosed is a clamping device that is useful in holding
material in place while it is having a manufacturing process
performed on it.  It is particularly useful in holding fragile or
brittle material which is subject to marring or breaking, such as a
thin sheet of copper or glass.

      The clamp works in the following manner:  The material 1 rests
on fixture 2 below the clamping device.  The clamping device consists
of a mounting bracket 3, pressure chamber 4, rubber diaphragm 7, and
bottom plate 8.  The assembly is held together with screws 10.  Air
pressure is applied to the pressure chamber 9 through air inlet port
5. Port 6 will be plugged if this clamp is the only one or the
last clamp in the system, or is connected to another air inlet port
of another clamp in the system.  Pressure in the pressure chamber 9
causes the rubber diaphragm to expand through the hole in the bottom
plate 8, pressing the material 1 against the fixture 2 clamping the
material in place.  The clearance between the bottom plate 8 and the
fixture 2 is set just slightly larger than the material thickness.
The drawing shows a simple spot clamp, but the device could take many
shapes, such as a long rectangle to clamp along the whole edge of the
material or around the whole perimeter of the material.  Also a
series of spot clamps could be used and linked together, and operated
