Abstract
Abstract In a driving tool for fasteners a driver has guide jaws releasably clamped thereagainst for holding a fastener in frontal alignment therewith. During driving movement of the driver together with said fastener towards a work piece, the guide jaws, in response to said fastener striking against the work piece, are arrested in spaced relation to the work piece and knocked loose from the driver for releasing the fastener from the guide jaws while the driver continues its driving movement. The driving tool may be provided with a magazine for band supported fasteners, which by an ejector are forced to break out laterally one by one from the band in between the guide jaws and by a feeder are moved together with the band one after the other to the ejector, said ejector and feeder being pivotally supported on a rocker member such as to alternately actuate the fasteners as the arm is rocked alternately in one direction and the other.

Claim 1
Independent Claim
205 words
In a driving tool including guIde body, a driver axially movably carried in said guide body, and a feed opening on said guide body, a driving tool magazine for supplying fasteners supported by a band one after the other through said feed opening into the path of movement of said driver, said magazine comprising a housing, a rocker member pivotally journalled in said housing adjacent said guide body in a plane transverse to said driver, an ejector movably mounted in said housing pivotally on the one end of said rocker member for pushing a leading fastener out of the band via said feed opening into the path of movement of said driver when said one end is rocked towards said feed opening and allowing said ejector to retract when rocked away from said feed opening, a feeder movably mounted in said housing pivotally on the other end of said rocker member for feeding forward the next fastener in said band to said feed opening when said other end is rocked towards said feed opening and allowing said feeder to retract when rocked away from said feed opening, and means for alternately rocking the ends of said rocker member towards and away from said feed opening.
Claim 2
Dependent Claim
205 words
In a driving tool including guIde body, a driver axially movably carried in said guide body, and a feed opening on said guide body, a driving tool magazine for supplying fasteners supported by a band one after the other through said feed opening into the path of movement of said driver, said magazine comprising a housing, a rocker member pivotally journalled in said housing adjacent said guide body in a plane transverse to said driver, an ejector movably mounted in said housing pivotally on the one end of said rocker member for pushing a leading fastener out of the band via said feed opening into the path of movement of said driver when said one end is rocked towards said feed opening and allowing said ejector to retract when rocked away from said feed opening, a feeder movably mounted in said housing pivotally on the other end of said rocker member for feeding forward the next fastener in said band to said feed opening when said other end is rocked towards said feed opening and allowing said feeder to retract when rocked away from said feed opening, and means for alternately rocking the ends of said rocker member towards and away from said feed opening.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
55 words
A driving tool magazine according to claim 2 in which said fasteners are supported in longitudinally spaced holes in said band substantially perpendicularly relative thereto, said housing being provided with a feeding slot for said fasteners extending along said guide passage and terminated at said feed opening, said guide passage passing all through said housing.
Claim 5
Dependent Claim
42 words
A driving tool magazine according to claim 1 in which said rocking means is a manually actuatable lever, a journal in said housing for the pivotal supporting of said rocker member therein, and said lever connected to said journal outside said housing.
