## Abstract

A torch device for household and construction applications is disclosed. The torch device includes a body that is shaped like a firearm having an aft handgrip, a forward handgrip, a trigger guard, and an igniter guard. The body provides a more convenient carriage of the torch and integrates safety features for the torch device. A fuel delivery assembly is coupled with a fuel source. An igniter is carried within the body and operable via the igniter guard. A nozzle tip is coupled with the torch head to discharge the fuel source into a torch head. A fuel delivery conduit communicates the fuel source between the nozzle and a trigger control operable via access through the trigger guard. The torch device provides for easier carriage and safer operation while conducting repair and maintenance tasks.

## Claims

### Claim 1

A torch device, comprising:
a body that is shaped like a firearm having an aft handgrip, a forward handgrip, a trigger guard, and an igniter guard;
a fuel delivery assembly having a proximal end configured to be coupled with a fuel source and a distal end carrying a torch head;
an igniter carried within the body and operable via the igniter guard;
a nozzle tip is coupled with the torch head to discharge the fuel source into the torch head;
a fuel delivery conduit communicates the fuel source between the nozzle tip and a trigger control operable via access through the trigger guard.

### Claim 2 (depends on 1)

The torch device of claim 1, fuel delivery assembly further comprising:
a fuel source conduit coupled with the trigger control,
a fuel shutoff valve is coupled to a proximal end of the fuel source conduit, is configured to couple the fuel source.

### Claim 3 (depends on 2)

The torch device of claim 2, the fuel delivery assembly further comprising:
a trigger regulator interposed between the fuel delivery conduit and the fuel source conduit; and
a control knob to adjust a flow rate of the fuel source through the trigger regulator.

### Claim 4 (depends on 3)

The torch device of claim 3, the fuel delivery assembly further comprising:
a pin and cap assembly moveably carried within the trigger regulator by operation of the trigger control.

### Claim 5 (depends on 4)

The torch device of claim 4, the fuel delivery assembly further comprising:
a plurality of seals that seal a pin of the pin and cap assembly within the trigger regulator; and
a cap contains a biasing spring configured to bias the pin to retain the trigger control in a normally closed condition.

### Claim 6 (depends on 5)

The torch device of claim 5, further comprising:
a fuel source coupled with the fuel shutoff valve.

### Claim 7

A method of operating a torch, comprising:
providing a torch device comprising a body that is shaped like a firearm having an aft handgrip, a forward handgrip, a trigger guard, and an igniter guard, a fuel delivery assembly having a proximal end configured to be coupled with a fuel source and a distal end carrying a torch head, an igniter carried within the body and operable via the igniter guard, a nozzle tip is coupled with the torch head to discharge the fuel source into the torch head, and a fuel delivery conduit communicates the fuel source between the nozzle tip and a trigger control operable via access through the trigger guard; and
connecting the torch device with the fuel source.

### Claim 8 (depends on 7)

The method of claim 7, further comprising:
operating a shutoff valve to deliver a fuel from the fuel source to a fuel source conduit.

### Claim 9 (depends on 8)

The method of claim 8, further comprising:
operating the trigger control to deliver the fuel to the torch head; and
operating the igniter to ignite the fuel.

### Claim 10 (depends on 9)

The method of claim 9, further comprising:
applying a flame from the torch head to a work surface.

### Claim 11 (depends on 10)

The method of claim 10, further comprising:
releasing the trigger control.
