## Abstract

A jewelry bench dust shield including a base attachable to a jewelry bench, an arm pivotally attached to said base, and a dust shield attached to said arm. A jewelry bench dust shield including a vacuum triggering pivoting arm, a trigger holding arm pivot base attachable to a jewelry bench, and a face plate connected to said arm. A jewelry bench dust shield including a base attachable to a jewelry bench, a vacuum trigger connected to said base having a wire connectable to a vacuum, an arm pivotally attached to said base, said arm having an extension portion which depresses said trigger when arm is lowered, and which releases said trigger when arm is raised, and a face plate connected to said arm.

## Claims

### Claim 1

A jewelry bench dust shield, comprising:
a base attachable to a jewelry bench;
a vacuum trigger connected to said base having a wire connectable to a vacuum;
an arm pivotally attached to said base, said arm having an extension portion which depresses said trigger when arm is lowered, and which releases said trigger when arm is raised, wherein the arm comprises a thin sheet with a thin top, a thin bottom and wide sides; and
a face plate connected to said arm.

### Claim 2

A jewelry bench dust shield, comprising:
a base attachable to a jewelry bench;
a vacuum line attached to the base;
a vacuum trigger connected to said base having a wire connectable to a vacuum;
an arm pivotally attached to said base, said arm having an extension portion which depresses said trigger which starts the vacuum when arm is lowered, and which releases said trigger and stops the vacuum when arm is raised, wherein the arm comprises a thin sheet with a thin top, a thin bottom and wide sides; and
a face plate connected to said arm.

### Claim 3 (depends on 1)

The jewelry bench dust shield of claim 1, wherein the face plate is curved.

### Claim 4 (depends on 1)

The jewelry bench dust shield of claim 1, wherein the arm pivotally attached to the base is configured to move in a plane defined by the thin top and thin bottom.

### Claim 5 (depends on 4)

The jewelry bench dust shield of claim 4, wherein the thin bottom of the arm has a generally upwardly concave shape.

### Claim 6 (depends on 5)

The jewelry bench dust shield of claim 5, wherein the generally concave shape of the thin bottom of the arm is configured such that there is sufficient working space for a jeweler's hands behind the face plate, below the arm and above a typical jeweler's bench anvil and jeweler's bench pin when the base is attached to a jewelers' bench immediately behind the jeweler's bench anvil and jeweler's bench pin.

### Claim 7 (depends on 1)

The jewelry bench dust shield of claim 1, wherein the face plate is curved.

### Claim 8 (depends on 1)

The jewelry bench dust shield of claim 1, wherein the arm pivotally attached to the base is configured to move in a plane defined by the thin top and thin bottom.

### Claim 9 (depends on 8)

The jewelry bench dust shield of claim 8, wherein the thin bottom of the arm has a generally upwardly concave shape.

### Claim 10 (depends on 9)

The jewelry bench dust shield of claim 9, wherein the generally concave shape of the thin bottom of the arm is configured such that there is sufficient working space for a jeweler's hands behind the face plate, below the arm and above a typical jeweler's bench anvil and jeweler's bench pin when the base is attached to a jewelers' bench immediately behind the jeweler's bench anvil and jeweler's bench pin.
