    • A heald frame for a weaving loom comprising an upper cross-member and a lower cross-member adapted to support healds directly therebetween. The upper and lower cross-members are joined together by spaced end members and a plurality of connection members spaced along the length of the cross-members between the end members and attached to the cross-members to restrain relative movement between the cross-members and retain a constant spaced relationship between the cross-members along their length. The connection members have portions of a narrow width extending between the upper and lower cross-members so that, during weaving, warp yarns pass the connection members without interference. First and second connection members are disposed, respectively, at opposite ends of each connecting member for causing reciprocation of the frame.
    • 一种用于织机的综框,包括上横向构件和适于直接在其间支撑综丝的下横向构件。 上横向构件和下横梁通过间隔开的端部构件连接在一起,并且多个连接构件沿着端部构件之间的横向构件的长度间隔开并且附接到横向构件以限制横向构件与横向构件之间的相对运动 沿着它们的长度保持横向构件之间的恒定的间隔关系。 连接构件具有在上横向构件和下横向构件之间延伸的窄宽度的部分,使得在编织期间,经纱无阻碍地通过连接构件。 第一和第二连接构件分别设置在每个连接构件的相对端,用于使框架往复运动。

    • The invention relates to apparatus wherein loom harnesses are operated by cams driven intermittently by respective drives rather than by cams fixed on a driven shaft. The harnesses are illustrated as being lowered by cams against yieldable resilient means tending to raise the harnesses, and the cams as being aligned with treadles carried longitudinally of the loom. Co-acting means are also provided for connecting respective chain drives at predetermined intervals to bearing members, rotatable on a fixed shaft, which carry cams fixed thereto as well as chain carrying sprockets rotatable thereon. The method contemplates operating the harnesses by timing the steps of rotating each cam in a predetermined sequence, and exerting a yielding force upon each cam tending to resist further rotation after the cam has turned on the fixed shaft through a predetermined arc.
    • 本发明涉及一种装置,其中织机线束由相应驱动器间歇地驱动的凸轮操作,而不是固定在从动轴上的凸轮。 线束被示出为被凸轮降低,可靠的弹性装置倾向于升高线束,并且凸轮与织机纵向承载的踏板对齐。 还提供了共同作用装置,用于以预定的间隔将各个链条传动装置连接到可在固定轴上转动的支承构件,该固定轴可承载固定在其上的凸轮以及可在其上旋转的链轮。 该方法考虑通过定时按照预定顺序旋转每个凸轮的步骤来操作线束,并且在凸轮已经通过预定的电弧接通固定轴之后,在每个凸轮上施加屈服力,以抵抗进一步的旋转。
