摘要:
The present invention is directed to a deck screw (10) intended for use with composite lumber, although it can be used with other wood products, such as pressure treated lumber. The deck screw of the present invention may be provided with a head (12) and a shaft (14) that has two regions of varying diameter. The upper region (16) has threads that exceed the number of threads of the lower shaft (18), on a unit length basis. The threads (17) of the upper shaft may be configured in an inverted buttress design. The lower region (18) of the shaft terminates at a tapered distal end (20) having a pointed tip (22) that leads the screw through the wood material. Threads (19) are provided on the lower region (18) of the shaft. The head (22) of the screw is provided with an upper surface (28), a lower surface (30), and a crown (32) that extends around the perimeter of the head. The crown (32) extends beyond the lower surface (30) of the head (12), forming a recessed region between the lower edge of the crown (32) and the shaft (14) of the screw. The head (12) may also be provided with an undercut (42). Further, the head (12) of the screw may be provided with a square driver opening (24) that permits the persons installing the screw to use a square bit. For instance the opening may be a #2 square driver opening. It should be understood that Phillips heads or flat heads in various sizes might also be employed.

Device for screwing screws through a hole of a plate into a base plate for securing insulating material said device having a magazine with plates and a magazine with screws. Said device having a screw driver which can be moved up and down. Said screw driver according to the invention feeds a plate and a screw towards their mating position in line with the screw driver during the upward stroke of the screw driver. Device is more simple and reliable screw magazine is a slit tube inclined to the horizontal.
摘要:
Die Erfindung bezieht sich auf eine klammerartige Blechmutter mit einem eine Gewindeprägung tragenden Gewindeschenkel (1) und einem mit einem Durchgangsloch (5) versehenen Klammerschenkel (2), wobei das freie Ende des Gewindeschenkels (1), das von dem Klammerschenkel (2) einen geringeren Abstand hat als die Dicke der zur Befestigung vorgesehenen Trägerplatte, eine vom Klammerschenkel (2) schräg aufragende Einführplatte (4) aufweist. Um die Blechmutter durch einen nach Möglichkeit flexiblen Führungskanal mit der Einführplatte (4) voraus mittels Druckluft ohne Verhakungsgefahr einer Montagepistole zuführen zu können, sind an den beiden Seitenkanten des Gewindeschenkels (1) im rechten Winkel Führungsstege (7) angeformt, deren Oberkanten (8) die Einführplatte (4) überragen und zum Klammerschenkel (2) parallel verlaufen und deren Außenflächen (9) den gleichen Abstand voneinander haben wei die Seitenkanten (10) des Klammerschenkels (2).
摘要:
An air-driven feeder tool (10, 10') is provided for presenting swagable collars (28) one at a time for placement on the shanks of lockbolts (16) and thereby made ready for the application of a swaging tool (30). The swaging tool (30) breaks off a pintail (63a, 63b) from the lockbolt (16) and a vacuum system draws the broken-off pintails (63a, 63b) through a vacuum device (66) and into a receptacle (70) for safe disposal. The feeder mechanism comprises a magazine (32) holding a supply of side-by-side collars (28), a presentation piece (34, 34') holding a short working collars and a worker-actuable trigger mechanism between the two queues for transferring collars (28), one at a time, from the magazine (32) to the presentation queue (34, 34'). Two embodiments of the feeder tool (10, 10') are disclosed, each with a unique trigger position.

摘要:
By advancing a feed rod (5) rotated and driven by inserting a threaded part (1) such as bolt and nut into a socket hole (6) at the front end, the threaded part (1) is supplied and tightened in the object such as screw hole or bolt. In the process of feeding, in order to prevent the part (1) from dropping off or dislocating, the part (1) is advanced to the vicinity of the object in the state being restrained by, for example, a closure member (31), and then the part (1) is inserted into the socket hole (6) of the feed rod (5), and then the fed rod (5) is further advanced until the part (1) arrives at the object and is tightened.
摘要:
Bei einer Vorrichtung zum Eindrehen von Schrauben mit Unterlegscheiben soll das Problem der selbsttätigen Zuführung der Schrauben und der Unterlegscheiben gelöst werden. Die Schrauben werden von einem seitlich angeordneten Magazin (11) über einen Trägerstreifen zugeführt und mittels der Greifer (24) in den Zuführschacht gebracht. Ferner ist ein Magazin (10) für die Unterlegscheiben vorgesehen, wobei diese Unterlegscheiben durch einen quer zur Einschraubachse verschieb- oder verschwenkbaren Schieber zugeführt werden. Die Steuerung der die Unterlegscheiben zuführenden Schieber und der die Schrauben einbringenden Greifer erfolgt in Abhängigkeit von der Vorschubbewegung der Schraubvorrichtung, wobei zu diesem Zweck verschiedene Steuerstangen (6, 7) und -zapfen vorgesehen sind, welche in Nuten von Drehkörpern bzw. an schwenkbaren Hebeln zur Anlage kommen. Durch besonderen Verlauf der Nuten und die Ausbildung der Hebel wird eine Dreh- oder Verschiebebewegung der erforderlichen Teile erreicht.
