Problems solved by technology

Due to the forces exerted by these tools, the fastener must be substantially perpendicular to the substrate, otherwise the fastener will bend or be knocked out and not secure properly to the substrate, or the fastener may bounce off the substrate

Embodiment Construction

[0017] Referring now to FIG. 1, there is shown a novel and improved carrier bar 10 for sequentially arraying fasteners 12 for use in a fastener driving tool. Carrier bar 10 can be used in many types of fastener driving tools, but is preferably used in explosive powder actuated tools. Each carrier bar 10 includes a carrier 14 having a plurality of sleeves 16 each clamping an associated fastener 12 . Each sleeve 16 is also new and improved, and the invention is not limited to multiple sleeves 16 clamping multiple fasteners 12 .

[0018] Each fastener 12 includes an elongated shank 18 and each sleeve 16 helps grip the shank 18 of the associated fastener 12 to keep the fastener 12 centered in the bore 42 of the sleeve 16 and correctly oriented so that the fastener 12 is aligned 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 tack, which may be made of hardened steel. Each fastener 12 is des...

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...
