A magazine assembly for a fastening tool. The magazine assembly slides on guide posts that are formed into the nose assembly of the fastening tool and is clamped to the fastening tool via a magazine clamp assembly that requires no tools to operate. The magazine clamp assembly may be partially released to permit the magazine assembly to be partially withdrawn from the nose assembly so that the nose assembly may be maintained without the complete removal of the magazine assembly. The construction of the nose assembly is such that when the magazine assembly is placed in a partially withdrawn state, a portion of the nose assembly mechanically inhibits actuation of the fastening tool trigger system.

Term end not estimated
The present invention generally relates to a fastening tool for dispensing fasteners from a magazine assembly into a workpiece and more specifically to an improved magazine assembly for a fastening tool.
A number of pneumatically operated devices have been developed for use in driving fasteners, such as staples and nails, into workpieces. These tools typically employ a magazine assembly for holding a plurality of the fasteners and feeding the fasteners into the nose of the tool prior to the installation of the fasteners into a workpiece.
Despite the wide spread use of such tools, several drawbacks have been noted. One such drawback concerns the dry-firing of the tool when an insufficient number of fasteners are contained in the magazine assembly. As is known in the art, the dry-firing of such tools tends to be harmful to the tool.
Additional advantages and features of the present invention will become apparent from the subsequent description and the appended claims, taken in conjunction with the accompanying drawings, wherein:
FIG. 1 is a left side view of a tool constructed in accordance with the teachings of a preferred embodiment of the present invention;
FIG. 2 is a right side view of the tool of FIG. 1;
With reference to FIG. 1 of the drawings, a fastening tool constructed in accordance with the teachings of the present invention is generally indicated by reference numeral 10. Fastening tool 10 is illustrated to include a detachable magazine assembly 20 and a fastening tool portion 30. The fastening tool portion 30 includes a nose assembly 40, a housing assembly 42, a cap assembly 44, an engine assembly 46 and a trigger assembly 48.
Nose Assembly
With reference to FIGS. 1 through 9, the nose assembly 40 is illustrated to include a nose structure 50, a contact trip 52, a trigger lever 54 and a contact trip-return spring 56. The nose structure 50 includes a nose body 60, a pair of magazine stabilizing tabs 62, a magazine flange 64, a pair of magazine guide posts 66, a mounting base 68, a spring post 70 and a pair of contact trip guides 72. The nose body 60 is generally U-shaped, with the legs 80 of the “U” being inwardly offset to form a semi-circular blade cavity 82. The inwardly offset legs 80 of the nose body 60 also serve as a guide surface 84 for guiding the lower front portion 86 of the contact trip 52. The contact trip guides 72 are coupled to the top of the nose body 60 and form a guide surface for guiding the portion 88 of the contact trip 52 that extends over the nose body 60.
