Abstract: In a strip of collated fasteners, each having a shank and a head, a carrier molded from a polymeric material has a sleeve for each fastener. Each sleeve has an annular portion and a breakable portion, which breaks into two segments as the fastener gripped by such sleeve is driven. The breakable portion, which is notched at one end, has a pair of similar, laterally opposed, outwardly opening, continuously curved concave recesses with open windows, from which portions of the fastener shank emerges. In a fastener-guiding tool, parallel ribs of a guiding device fit into such recesses, into close proximity with the emerging portions, so as to guide the strip between such ribs.

Abstract: A strip of collated nails wherein, upon each side of the strip, a tape extends across and is adhered to a flat surface defined by means of a tape recess of the shank of each nail, and between two end surfces defined thereby. Each tape is adhered by means of an adhesive layer between such tape and the flat surfaces upon each side of the strip, at an acute angle relative to two axially extending sides of the flat surfaces upon each side of the nail shank.

Abstract: Wire nails are collated by means for conveying the nails in a specified manner and by means comprising a wheel for engaging keyways defining flat surfaces on the shanks of the nails. Each nail is rotated by the wheel, about an axis of the shank of such nail, to such extent as may be then necessary to orient the keyways of such nail and of other nails with such surfaces defining a plane. The wheel fits between end surfaces defined by the keyways so as to cause the keyways that have been engaged by the wheel to define a continuous channel.

Abstract: A wire nail with a head having a circumferential edge conforming to a complete circle and disposed in a radially offset relationship with respect to a shank. A flat surface on defined upon the shank provides a datum indicating where the shank is located. A flat surface on the shank provides a datum for orienting such nail and similar nails. In some embodiments, a tangent plane defined by means of a lower or underside portion of the head is oriented at an acute angle (75.degree. to 85.degree.) relative to the shank. In a strip of such (collated) nails, the flat surfaces defined upon the shanks define an open channel, which coacts with a rib integrally provided upon one wall of a nail-feeding mechanism. In a nail-making machine, two gripping members defining an annular recess and a punch are used to form such a nail from a wire of a malleable metal.

The machine comprises a shuttle arranged to displace the lowermost washer from the stack when it is desired to dispense such washer. The shuttle includes a novel arrangement of means overlying and underlying marginal portions of such washer.

Abstract: Method for making a capacitive structure. In a first mode, one coil of the interleaved webs is made from a laminate comprising a carrier tape, and two metallized, dielectric films, which may be ultra thin. One such web is wound into a coil. The other web and the carrier tape are twisted, by one half-turn, and wound over such one web and the carrier tape is peeled away so that the webs are interleaved. In a second mode, two coils of the interleaved webs are made from two laminates, each as described. One such web from one such laminate and one such web from the other laminate are wound into each coil so that the webs are interleaved. Techniques for providing each web with demetallized lanes and for slitting the webs into ribbons are disclosed. The carrier tape can be optionally omitted in some instances.

Abstract: An index rotary switch includes a housing, stationary contact members, a rotor contact member, and a pushbutton-operated actuator device. The stationary contact members are disposed within the housing for defining an infinite number of alternately achieved on-and-off positions. The rotor contact member is disposed for rotation within the housing for wipingly engaging the stationary contact members. The rotor contact member is formed with a rectangularly-shaped flat portion and a plurality of resilient L-shaped arms extending downwardly from respective edges thereof. The L-shaped arms have arcuate-shaped contacts formed upon their free ends so as to wipingly engage the stationary contacts. The actuator device is disposed within the housing and is operatively connected to the rotor contact member for sequentially rotating the rotor contact member so that the arcuate-shaped contacts alternately index with respect to the on-and-off positions upon successive actuations of the actuator device.

Abstract: Apparatus for stacking a web in a cut or zigzag folded condition. A supply conveyor overlies a reciprocating transport conveyor. The transport conveyor passes over a skid onto which cut or stacked web is to be disposed. The velocity of reciprocation of the transport conveyor is timed to the speed of the supply conveyor. The transport conveyor is an endless belt having brakes to alternatively seize its upper or lower run as the conveyor is reciprocated.

Abstract: A machine for fastening one or more layers of roofing material to an underlayment, and a stackable washer therefor. A chute receives a stack of such washers. A shuttle displaces a single washer to a separated position when moved in one direction, to which the shuttle is biased, and releases the single washer when moved in the opposite direction. A gate, which cooperates with camming surfaces defined upon the respective washers, restrains the overlying washer within the stack against being displaced along with the single washer and restrains the single washer from being displaced from the separated position. Various components are provided by linking a stand-up screw gun of a known type to the shuttle. The stackable washer is embossed so that each such washer and like overlying and underlying washers within a stack contact each other at three or more places, which define tangent planes intersecting planes defined by planar areas upon such washers at angles greater than 45.degree. but less than 90.degree.

Abstract: Electrostatic coating apparatus including apparatus for establishing an electrostatic field for indirectly charging atomized droplets of paint or other coating material discharged from an atomizer.

The tube is formed from an insulating outer layer and a semi-conducting inner layer having a high distributed resistance. The pins extend through the inner layer which is connected through a large resistance to a high voltage power supply. The apparatus is particularly useful for charging electrically conductive and semi-conductive materials delivered to the atomizer from a grounded source.

Abstract: A method of making a plastic terminal connector having a metal terminal set embedded therein in which the conductive contact members of the terminal set are electrically isolated from each other prior to the injection molding process. There is included a three-plated mold base which is formed from a lower movable mold plate, an intermediate mold plate, and an upper stationary mold plate. The upper mold plate includes a plurality of punches which extend through the spring-biased intermediate mold plate so as to cut connecting ties of the metal terminal set so as to form a plurality of individual electrically isolated conductive contact members when the mold is closed. The cutting operation is performed prior to the injection molding process as an integral part of loading the metal terminal set into the lower mold plate and securing the terminal set within the mold between the lower and intermediate mold plates when the mold is closed.

Abstract: Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles. For each carrier, integrally joined band segments define container-receiving apertures. Moreover, an integral handle is joined at its ends respectively to middle portions of two outer segments, which are joined to one cross segment at a node. Stresses are distributed from each end of the handle, through the outer segment having such end joined to a middle portion thereof, to two cross segments. Perforated lines divide alternate cross segments into half segments and facilitate severance of such stock to form the individual carriers. Each half segment has an aperture-defining edge configured to provide means, which may comprise a nub, for countering tendencies of such half segment to neck down or to break.

Abstract: An improved carrier tape is disclosed comprising an elongated base strip and an elongated cover strip both formed of a plastic film material. The base strip is provided with longitudinally spaced cavities for components to be transported therein as well as a series of spaced, longitudinally extending sprocket drive holes for advancing the tape. The cover strip has a raised hump on its top surface positioned so as to align with the sprocket holes when the tape is assembled. The hump defines a living hinge for the adjacent surfaces of the cover strip top face. Accordingly, when the hump is depressed the sidewalls of the cover strip move outwardly so as to clear the edges of the base strip. Conversely, when the hump is released, the sidewalls return to their relaxed position. A device for applying the cover strip to the base strip applies pressure to the hump of the cover strip while guiding the sidewalls of the cover strip around the top edge of the base strip.

Abstract: An anchoring device having a head and a shank integral with the head and adapted to be forcibly driven into a hole having a cylindrical wall defined within a body of concrete, masonry, or like material. The shank has a spring temper and has a proximal portion, a distal portion, and a transitional portion joined to the proximal portion at a proximal elbow and to the distal portion at a distal elbow. Each such portion is substantially straight when the shank is unstressed. The shank has a substantially uniform, substantially circular cross-section, except at the elbows, where the shank has smaller cross-sections causing the shank to be preferentially bendable at the elbows. Each of the proximal and distal portions has an axial length equal to at least approximately twice its diameter. The transitional portion has an axial length approximately equal to its diameter. The distal portion facilitates initial entry of the shank into the hole.
