    • 2745. Napier & Son, D., Rainforth, W. F., and Andrews, W. J. Feb. 4. Drilling-machines; tapping.- In a multiple-spindle machine for tapping, drilling, or similarly treating nut or other blanks of the type in which an intermittently-rotated blank-holder brings the blank opposite the tool, and in which the tool has a long shank to receive the finished articles, the forward movement of the turret workholder advances the blanks on to the tool and displaces a feedconduit towards a fixed part to feed the blanks to the workholder. In the form shown, two caps D are mounted in split chucks B operated by the usual grip and release mechanism controlled by a lever B and rotated by a belt and gearing connecting the two spindles. A work-holder E, which may be provided with three or more series of holes of different sizes to suit the size of blank, is adjustable ruund its spindle E and clamped in position by a nut, the position being determined by holes in the holder engaging pins in the spindle E . The blanks abut against screw stops E and are also held in the work-holder by spring-pressed balls. The workholder is moved towards the tools by a handle F through a rack and pinion, and the spindle is rotated by a .pin E on the support E engaging V-grooves in the spindle. Two V-grooves are provided so that the work-holder rotates in the same direction in either direction of traverse of the work-holder Straight grooves e are used for guiding the work-holder during the cutting operation. Two feed chutes H with openings H for the removal of the blanks are mounted on a slide H pressed by a spring against the workholder, and when the latter is fed forward blanks are pressed into the work-holder, while other blanks are being cut, by fixed stops. When the workholder abuts the plate G', the blanks are drawn from it and are guided over the tool by suitably shaped removable abutments and received on the tool spindle. By turning the handle F the workholder is withdrawn and partially rotated, and then fed forward again. The stops may be moved instead of the conduits.

    • A joining arrangement is provided for use in the construction of stud frame which includes a releasable attachment/detachment feature. The first member (plate) includes in at least one side wall a formation which, when members are joined, engages a corresponding formation in at least one wall of the second member (stud). The formation, such as a V-shaped protrusion, is/are disposed at an angle to the longitudinal axis of the member and the formation on the second member is disposed generally parallel to its longitudinal axis such that upon engagement of the first and second members, the respective formations in the first and second members engage such that they are in alignment, thereby, securing the first member to the second. Additionally, a plurality of protrusions, which provide a gripping feature, may be formed on the upper surface of web for inhibiting the stud from sliding, slipping, moving and/or migrating within the plate.
    • 提供了一种用于构造螺柱框架的接合装置,其包括可释放的附接/拆卸特征。 第一构件(板)在至少一个侧壁中包括当构件接合时与第二构件(螺柱)的至少一个壁中的对应地层接合的构件。 诸如V形突起之类的结构被设置成与构件的纵向轴线成一定角度,并且第二构件上的结构大致平行于其纵向轴线设置,使得在第一和第二构件 ,第一和第二构件中的相应构造使得它们对齐,从而将第一构件固定到第二构件。 此外,提供抓握特征的多个突起可以形成在幅材的上表面上,以防止螺柱在板内滑动,滑动,移动和/或迁移。
