Abstract: 1730. Hunter, S. van A. Jan. 25. Measures of length.-Relates to apparatus for winding, and measuring the length of yarn or other material being wound, and is described in connection with a Leeson winding-machine. The yarn may be cut to determined lengths and the machine may be automatically stopped either when a predetermined length has been wound or the material breaks or fails. The apparatus also indicates the total length of material which has passed through the machine. The yarn is passed round a measuring-wheel j<1>, which is connected by toothed gearing with a disc m<1> carrying a pointer w, which indicates the total length wound on a graduated portion of the frame. The disc m<1> is provided with a number of radially sliding or pivoted spring bolts, which are supported at their inner ends upon an adjustable cam disc m<11>, so that all the bolts may be withdrawn within the periphery of the disc m<1>, or one or more of them may be caused to project beyond it. When a projected bolt arrives in its highest position as the disc rotates, it raises a vertically-movable and horizontally-sliding bar o into such a position that a projection n<11> thereon may be engaged by a toothed cam n on one of ths intermediate shafts between the measuring-wheel or pulley j<11> and the disc m<1>. When the bar o is moved horizontally by the tappet n, its notched end q<11> operates the spring knife r, which, in conjunction with a suitably prepared edge of the carrying bracket, severs the thread and also returns the bar o to its original position. When the bar o is moved to the left, a projection x thereon also operates a catch lever x<1>, whereby a spring cam lever is released, the said cam lever being mounted on the stopping bar or lever in such a manner that, when released, its cam-shaped extremity engages with the boss of the starting-lever and causes the stoppage-of the machine. During the passage of the yarn to the measuring-pulley, it is passed over a tension lever at one end of which is a brake, which, should the yarn break or become too slack, engages with one of the flanges of the measuring- wheel and stops the registering-mechanism. When winding and measuring only short lengths of yarn &c., the disc n may be provided with a pointer, which travels over a graduated dial on the frame. The cam disc m<11> may be clamped to the disc m<1> in any one of a number of desired positions by means of a spring pin, which may be passed through an aperture in an arm v on the cam disc m<11> and through one of a number of apertures in the disc m<1> the said apertures being marked with numbers, which correspond with the number of spring bolts which project beyond the periphery of the disc. For indicating still greater lengths of yarn &c., the shaft of disc m<1> may be caused to operate a further set of numbering discs &c. The disc n may also be provided with movable bolts in the same manner as the disc m<1>; q<1> is a lever carrying a spring q, by means of which the bar o may be raised or lowered by hand, as desired. When in the raised position, the bar o is operated by every projection n' on the disc n, while, when in the lower position, the bar o is only engaged by the tappets n' when it is raised by the bolts of the disc m<1>.
