Embodiment Construction

[0020] Figure 1 is a die-cast open frame hand-held filler gun with a handle 90 extending down and a screw down trigger of the present invention similar to the apparatus shown in Figure 1 of co-pending patent application Ser. No. 08 / 586,187. According to an example of the present invention, the gun described here includes a unique barrel point cutter assembly 100, which generally has a cutting frame 120 fixed to the opposite rear of the frame 20 and a blade assembly attached to the upper part of the trigger 22. Into 130.

[0021] FIG. 2 is a disassembled side view of the barrel point cutter assembly 100 in FIG. 1 . Cutting frame 120 is constructed of metal or other rigid material and has a central bore 128 for insertion into the end of a conventional stuffing cartridge. Cutting frame 120 is attached to the plastic frame of the gun by one or more conventional rivets 140 or other suitable anchors. It is important that the cutting frame 120 is firmly anchored to the frame 20 to ...

Abstract

Simple, inexpensive and efficient tip cutting assemblies for allowing an operator to cut the tip of a fresh cartridge of caulk prior to insertion in the barrel. In one embodiment a closed metal-frame gun includes an aperture through a side of the housing for insertion of a cartridge tip, and a tip-cutting member formed with a through-hole to pass the plunger shaft and riding thereon within the housing. The tip cutting member extends a cutting blade flush along the inner surface of the housing, and the tip-cutting member is moveable by operation of the trigger across the aperture. A fresh cartridge tip can be cut by insertion in the aperture and by retraction of the trigger such that the tip-cutting blade cuts scissor-like across the aperture and through the tip.

Description

technical field [0001] The present invention relates to a filling mechanism, and more particularly to a hand-held filler gun for injecting filler from a disposable filler cartridge. Background technique [0002] Inexpensive brands of filling guns are usually the manual trigger type, which includes a one-way grip assembly to push the piston rod forward to inject the filler in the barrel. [0003] An example of such a gun can be seen in Copending Patent Application No. 08 / 586,187, filed January 16, 1996 by the aforementioned applicant. That application describes a variety of gun constructions, all incorporating the novel non-drip drive impedance assembly. For example, a molded open-frame hand-held filling gun is shown in Figure 1 of the reference application. The gun generally has a forward frame 10 for slidingly guiding a piston 12 mounted at the end of a tappet 14 . The frame shown is suitable for carrying typical packing cartridges. Tappet 14 is mounted at part 20 of th...
