Example Embodiment

[0017] Referring now to FIG. 1, there is shown a novel and improved carrier strip 10 for arranging fasteners 12 in sequence for use in fastener driving tools. The carrier strip 10 can be used in many types of fastener driving tools, but it is preferably used in tools actuated by explosive powder. Each carrier strip 10 includes a carrier 14 with a plurality of sleeves 16, and each sleeve 16 clamps an associated fastener 12. Each sleeve 16 is also new and improved, and the present invention is not limited to a plurality of sleeves 16 clamping a plurality of fasteners 12.

[0018] Each fastener 12 includes an elongated shank 18, and each sleeve 16 helps to clamp the shank 18 of the associated fastener 12 to keep the fastener 12 in the center of the hole 42 of the sleeve 16 And have the correct orientation to align the fastener 12 with a central axis 20 passing through the sleeve 16.

[0019] A representative fastener 12 is shown in FIG. 2. Each fastener 12 is a positioning pin, which...

Abstract

In a fastener driving tool, a carrier for holding a plurality of fasteners comprises a plurality of sleeves, each sleeve holding an associated fastener. Each sleeve has a body with an axis and a bore, the bore extending axially through the body and the bore being for receiving the associated fastener. A set of compressible ribs is also included within the bore of the sleeve for gripping a shank of the associated fastener so that the associated fastener is positioned substantially in the axial direction of the sleeve when the fastener is driven. Each rib has a curved portion that is concave with respect to the bore.

Description

technical field [0001] The present invention relates to an array of fastener carrying strips, such as tacks, for use with fastener driving tools actuatable by methods such as gasoline combustion or explosive gunpowder. Background technique [0002] Fastener driving tools, such as those actuated by combustion power or explosive powder, are widely used to drive fasteners into substrates. Such fasteners include set pins designed to be driven into cement, stone or steel by force. [0003] Fastener driving tools can be used with fastener carrier bars or magazines fitted with sequential arrays for quick and easy feeding of fasteners to the driving tool. Typically, these carrier strips use a carrier molded from a glue such as polypropylene or other plastic, in which each sequential fastener has a separate sleeve bushing collar. There may be at least one frangible bridge between each sleeve and its adjacent sleeves to allow each sleeve to be easily detached from the carrier. US P...
