## Abstract

A caulking cannon having a motorized plunger-moving component configured to drive a plunger shaft along an axis that is substantially parallel to a caulking-cannon longitudinal axis; a cartridge-holding barrel component coupled to the motorized plunger-moving component; a handle coupled to the cartridge-holding barrel component; a caulk exit-port component coupled to the cartridge-holding barrel component; wherein the plunger shaft is configured to move in a first direction parallel to a caulking-cannon longitudinal axis and thereby enter into a volume of space within the cartridge-holding barrel component; wherein the cartridge-holding barrel component is configured to hold a caulk cartridge having a fluid-chamber volume of at least three-fourths of a gallon; wherein the motorized plunger-moving component has a hand grip; and wherein the caulk exit-port component is configured to channel caulk fluid flow from the caulk cartridge to an exit orifice.

## Claims

### Claim 1

A caulking cannon comprising:
a motorized plunger-moving component configured to drive a plunger shaft along an axis that is substantially parallel to a caulking-cannon longitudinal axis;
wherein a plunger handle is attached to an outer end of the plunger shaft;
a cartridge-holding barrel component coupled to the motorized plunger-moving component;
the cartridge-holding barrel component having a rear wall and a front wall protruding outward from the cartridge-holding barrel component and defining a longitudinal length of the cartridge-holding barrel component and a longitudinal length of a caulk cartridge being inserted into the cartridge-holding barrel component;
a caulk exit-port component coupled to the cartridge-holding barrel component;
wherein the plunger shaft is configured to move in a first direction parallel to the caulking-cannon longitudinal axis and thereby enter into a volume of space within the cartridge-holding barrel component;
wherein the cartridge-holding barrel component is configured to hold the caulk cartridge having a fluid-chamber volume of at least three-fourths (¾) of a gallon;
wherein the motorized plunger-moving component has a first hand grip and is turned off and on by using a trigger on the first hand grip;
wherein the caulk exit-port component is configured to channel caulk fluid flow from the caulk cartridge to an exit orifice;
a handle coupled to the cartridge-holding barrel component providing a user with a second hand grip for holding the caulking cannon;
wherein the handle is oriented towards the rear wall at an angle ranging from about 30 to about 90 degrees relative to the caulking-cannon longitudinal axis;
wherein the handle has a load capacity of at least 15 pounds.

### Claim 2 (depends on 1)

The caulking cannon according to claim 1, wherein the cartridge-holding barrel component is removably coupled to the motorized plunger-moving component.

### Claim 3 (depends on 1)

The caulking cannon according to claim 1, wherein the handle has a load capacity of at least 20 pounds.

### Claim 4 (depends on 1)

The caulking cannon according to claim 1, wherein the handle has a load capacity of at least 25 pounds.

### Claim 5 (depends on 1)

The caulking cannon according to claim 1, wherein the caulk cartridge is an enclosed volume that is substantially cylindrical and has at least one removable end.

### Claim 6 (depends on 1)

The caulking cannon according to claim 1, wherein the caulk cartridge is a bucket with orifices at a top and bottom of the bucket.

### Claim 7 (depends on 1)

The caulking cannon according to claim 1, wherein the caulk cartridge is a sausage barrel assembly.

### Claim 8 (depends on 1)

The caulking cannon according to claim 1, wherein a longitudinal length of the caulking cannon, not including a length of the plunger shaft, is at least 42 inches.

### Claim 9 (depends on 1)

The caulking cannon according to claim 1, wherein a longitudinal length of the caulking cannon, not including a length of the plunger shaft, ranges from 42 inches to 60 inches.
