Abstract

An apparatus includes a splash shield incorporating a clear viewing area, a vacuum manifold, the vacuum manifold adapted to releasably engage the splash shield, a light assembly removeably linked to a lower surface of the vacuum manifold, and a port emanating from the vacuum manifold, the port configured to attach to a vacuum system wherein application of a vacuum creates a laminar flow to draw vapor away from the splash shield.

Claims (27)

1. An apparatus comprising:

a splash shield incorporating a clear viewing area;

a vacuum manifold, the vacuum manifold adapted to releasably engage the splash shield;

a light assembly removably linked to a lower surface of the vacuum manifold; and

a port emanating from the vacuum manifold, the port configured to attach to a vacuum system wherein application of a vacuum creates a laminar flow to draw vapor away from the splash shield,

wherein the splash shield comprises posterior indents along its perimeter that engage corresponding detents in a side wall of the manifold assembly.

2. An apparatus comprising:

a splash shield incorporating a clear viewing area;

a vacuum manifold, the vacuum manifold adapted to releasably engage the splash shield;

a light assembly removably linked to a lower surface of the vacuum manifold;

a port emanating from the vacuum manifold, the port configured to attach to a vacuum system wherein application of a vacuum creates a laminar flow to draw vapor away from the splash shield,

wherein the light assembly comprises:

a lamp;

a flexible neck; and

a lamp base, the flexible neck linking the lamp to the lamp base.

3. The apparatus of claim 2 wherein the lamp base includes a power supply connection.

4. The apparatus of claim 2 wherein the lamp base includes a battery.

5. The apparatus of claim 4 wherein the battery is rechargeable.

6. An apparatus comprising:

a splash shield incorporating a clear viewing area;

a vacuum manifold, the vacuum manifold adapted to releasably engage the splash shield;

and a light assembly removably linked to a lower surface of the vacuum manifold, the light assembly comprising a lamp, a flexible neck, and a lamp base, the flexible neck linking the lamp to the lamp base.

7. The apparatus of claim 6 wherein vacuum manifold includes a port configured to attach to a vacuum system wherein application of a vacuum creates a laminar flow to draw vapor away from the splash shield.

8. The apparatus of claim 6 wherein the splash shield comprises posterior indents along its perimeter that engage corresponding detents in a side wall of the manifold assembly.

9. The apparatus of claim 6 wherein the lamp base includes a power supply connection.

10. The apparatus of claim 9 wherein the lamp base includes a battery.

11. The apparatus of claim 10 wherein the battery is rechargeable.
