Abstract: An adjustable fastening device comprises a slider and a rack which cooperate to adjustably fasten two parts of an article, or two separate articles, together. The slider has a pair of ears projecting laterally from the top wall of its body and at least partly elevated above the plane of the top wall. A separate anchoring member is provided which is to be placed over the ears and the intervening top wall portion via one of the article parts. The anchoring member includes a boss to be received in the interspace between the elevated ear portions via the article part, and a plurality of piercing fingers to be thrusted through the article part and to be clinched against the ears.

Abstract: A sliding clasp fastener including interlocking elements of a continued meander structure which are disposed astride a longitudinal tape edge at their leg and connecting portions. The leg and connecting portions are deformed to provide flattened, enlarged undersurfaces adapted to be held in intimate contact with the tape. The connecting portions are also deformed to produce recesses for receiving therein side flanges of a slider.

Abstract: There are disclosed a method and apparatus for coupling or pairing, prior to attachment to fastener carrier tapes, two single rows of continuous elements for a slide fastener into a double element row, the two rows having been discharged respectively from a pair of separately located element shaping and transporting machines having different power sources. The speeds of both of discharge of the two single element rows and of withdrawal of the combined or double element row are selectively changed with the two single element rows advanced under constant tension, in order to ensure accurate and efficient coupling of the element rows even in the event the two machines operate out of complete synchronism to discharge the element rows at different rates of speed.

Abstract: In a window assembly having a pair of sashes mounted within a supporting frame for relative horizontal movement, each sash is integrally provided with a pair of opposed rims defining an outwardly open channel along each of its top and bottom horizontal members and along one of its side vertical members which is to be held against one of the jambs of the supporting frame upon closure of the sash. When the sashes are moved to their closed positions, a plurality of vertical rolls mounted in selected positions inside the channels of each sash ride on respective raised roll seats formed on stationary flanges intruding into the respective channels from the supporting frame. Upon resulting lateral displacement of the sashes relative to the supporting frame, sealing strips also arranged internally of the channels become pressed against the flanges.

Abstract: An automatically locking type of slider is disclosed for use with a slide fastener, which slider incorporates locking means to lock the slider into position on the fastener stringers. The locking means consists of a resilient plate member centrally bent into a U-shaped structure with two arm portions, one of which arm portions is provided with a support lug or lugs at one end and a locking prong at the other engageable in locking relation with the fastener stringers. The support lug is engageable in an aperture formed in the slider body in such a manner as to restrict free movement of the locking means during manipulation of the pull tab.

Abstract: Fastener assembly apparatus including a slider holder for holding a slider in upside-down disposition for the assemblage of a fastener chain in the form of a continuous length of coupled stringers. A stringer separator is mounted on the stringer exit side of the slider holder to permit the fastener stringers to be separated away from each other in a streamlined fashion as they emerge uncoupled out of the flared front end of the channeled slider body on the slider holder. In case a pair of oppositely directed sliders are to be assembled with each fastener length of the chain, a stringer guide is additionally mounted on the stringer entrance side of the slider holder to cause the fastener stringers to be introduced uncoupled into one of the sliders on the slider holder through its flared front end in a streamlined fashion.

Abstract: A method of manufacturing slide fastener stringers having a row of continuous coupling elements which is spirally coiled and woven into the fabric tape simultaneously with the weaving of the latter. There is provided a shuttle for carrying an element-forming filament which is interwoven with warp yarns forming the tape edge and looped over a mandrel wire located adjacent the tape edge by reciprocal, transverse movement of the shuttle. The shuttle is rotated about its central axis during one cycle of the reciprocal movement thereof to eliminate a twist or torsion on the filament imparted by the shuttle reciprocally passing alternately over and under the mandrel wire.

Abstract: A slider holder including a support structure having a slider mount on a top portion thereof. The slider mount has a top surface inclined to the plane of the horizon for receiving and positioning a slider upside down with the bottom end of the slider directed downwardly and with the guide channels of the slider inclined to the plane of the horizon. A lever having a detent is turnably supported to engage and disengage an opening of the slider pull tab and releasably lock the slider in the slider mount. In use, a pair of stringers mounted on an article and having elastically deformable fastener elements are successively pulled through the slider guide channels in a downward direction and positioned so that the fastener elements are aligned. The stringers are then simultaneously pulled upwardly through the guide channels to engage the fastener elements, and the slider is then released from the holder.
