Abstract
A dual component caulking gun which utilizes a gun body to which there is affixed a dual component cartridge assembly designed to carry dual component cartridges. A ball screw is journaled within the gun body for rotary motion but locked against axial motion and extends in a direction opposite the component cartridge assembly. A pair of ram rods are journaled through the gun body and terminate at the first end in ejector rams and at their opposite end in a transfer bar that is interconnected to the ball screw by means of a ball screw nut.

A dual component mechanical caulking gun comprising:
- a gun body;
- a dual component cartridge assembly affixed to the gun body on a first side of the gun body;
- an elongate threaded screw locked within the gun body against axial movement but journaled within the gun body for rotary motion and extending from the gun body in a direction opposite to the first side of the gun body and parallel with the cartridge assembly;
- a pair of ram rods extending through and journaled within the gun body for axial movement within the gun body in a line parallel with the elongate screw and each terminating in a ejector ram at a first end thereof on the first side of the gun body and adjacent the cartridge assembly and terminating at their opposite ends on the opposite side of the gun body in a transfer bar;
- and
- thread engaging means interconnected between the transfer bar and the threaded screw whereby rotation of the threaded screw will move the transfer bar and ram rods and ejector rams relative to the gun body in eject and retract directions.
