A magazine (103) includes a nail guide surface (106) and a movable guide wall (109). The nail guide surface (106) is linear and continuous to a nail introducing opening (105) and has a shoulder (107) for supporting the nail heads of a connected nail assembly (104). The movable guide wall (109) is confronted with the nail guide surface (106). In the magazine (103), a plurality of connected nail assemblies (104) are loaded and placed in side-by-side relation, while being in contact with each other, between the nail guide surface (106) and the movable guide wall (109). The plurality of connected nail assemblies (104) are pressed against the guide surface (106) of the magazine (103) by means of a pressing members (111) provided on the movable guide wall (109). The movable guide wall (109) is turned, for opening and closing, between a position being confronted with the nail guide surface (106) of the magazine (103) and a position at which the nail guide surface (106) is opened.

摘要:
A fastener detection system (70) is provided for both internal combustion and powder actuated fastener driving tools (10). A sensor (54) disposed at a portion of a fastener supply path (38) detects the presence or absence of a fastener (46). An indicator (60) notifies an operator when the sensor (54,55) detects the absence of a fastener. In the combustion tool (10), either or both of fuel delivery and combustion ignition may alternatively or also be disabled when no fastener (46) is detected.
摘要:
A tack-driver has a magazine (4) consisting of a magazine section (11) firmly secured to the tacker and a thrust member with a base plate (20) movable longitudinally therein. In order both to obtain a strong thrust member securing force and to be able to open the magazine easily, a movable handle (16) is fitted on the thrust member to which is coupled a contact member (25). With the handle (16) closed, the contact member (25) presses counter-supports (22) against a stop spring (18). With the handle (16) open, however, the counter-supports (22) can enter recesses (27) in the contact member (25) and release the stop spring (18).
摘要:
Am pneumatischen Schlagbolzen (12) ist vorne eine Mulde (12a) gebildet, zur Aufnahme des Kopfes des einzuschlagenden Nagels. Dieser wird dabei durch einen Doppelhebel (27) achsgleich mit dem Schlagbolzen gehalten, so daß er beim Niedergehen des Schlagbolzens in dieser Stellung bleibt und präzise eingeschlagen wird. Der Doppelhebel steht über Gestänge mit dem Auslösehebel (20) für die Pneumatik derart in Verbindung, daß er vor Auslösung der Pneumatik sich zurückbewegt, den vordersten Nagel in einer Gleitschiene (18) aufnimmt und diesen am wiederhochgegangenen Schlagbolzen ansetzt. Die Gleitschiene erhält fortlaufend die Nägel aus einer sich langsam drehenden Trommel (36) in welche die Nägel lose eingebracht werden.
摘要:
Method and apparatus for inserting fasteners into holes in a workpiece. The apparatus includes finger carrying means (10) which are carried by an anvil (12) for telescoping movement relative to the anvil, the finger carrying means including a bore (36) coaxial with the anvil and through which the anvil may pass as it moves from a raised position to a lowered position. The finger carrying means is provided with a side port (38) through which fasteners (R) may be inserted by a gravity injector, the side port being disposed below the anvil when it is in its raised position. A plurality of annular arrays of resilient fingers (54) are mounted in the bore below the side port. A fastener (R), after being injected into the bore of the finger carrying means, is pushed by the anvil through the fingers as the anvil moves to its lowered position, the annular arrays of resilient fingers properly orienting the fastener in coaxial alignment with the anvil and with a hole in a workpiece.
摘要:
A fastener-driving device, intended for driving fasteners such as nails, screws etc., includes a fastener receiving and guiding means (15) for receiving fasteners (17) in a position for co-action with a fastener-driving means (14) and for guiding the fasteners towards the intended fastener-driving location; a fastener magazine (19) having a fastener guide channel (22) for guiding fasteners arranged in side-by-side relationship towards the fastener receiving and guiding means (15); and a feed means (29, 48) for feeding fasteners arriving from the magazine (19) to the fastener receiving and guiding means. The feed means (29, 48) includes a bifurcate member (29) arranged to co-act with the guide channel in the magazine (19). The bifurcate member (29) has an elongate recess or groove (33) flanked by the tines or legs (31, 32) of the bifurcate member, and the width of the groove is adjusted to receive one fastener (17) at a time. For the purpose of feeding fasteners one at a time, the bifurcate member (29) can be pivoted forwards and backwards from a fastener-receiving position, in which the groove (33) is directed obliquely towards the magazine (19) and the mouth of the groove extends across at least substantially the whole width of the guide channel, via an intermediate position, in which the groove extends transversely over the whole of the guide channel (22), to and beyond a position in which the groove (33) extends obliquely towards the fastener receiving and guiding means (15) and the mouth of said groove extends across at least substantially the whole width of the guide channel. The edges defining the mouth of the groove are formed by the outer ends of the legs or tines (31, 32) of the bifurcate member, and that edge located nearest the magazine in the fastener-receiving position of the bifurcate member (29) forms an acute angle with the symmetry plane (38) of the guide channel.
