setting-on handle, by means of which the attendant can bring the bobbin very gradually in contact with the driving drum, instead of its being allowed to tumble against it. The jerking start made with the last-named method very frequently breaks the threads again, especially when tender and fine yarns are being wound. By the improvement described these breakages are avoided. Another is the introduction of an adjustable weight, which is carried upon a lever attached to and projecting backwards from the bobbin cradle. This is a novel application, so far as this type of machine is concerned, and by its means the pressure of the bobbin upon the drum can be made heavy or light as may be desired. An improvement has also been effected in the gearing through which the traverse motion is actuated, which renders the driviDg of the traverse very simple and noiseless. This consists of the introduction of a pair of helical wheels instead of the bevels ordinarily employed for transmitting power from the drum shaft to the short horizontal shaft carrying the heart cams. The connection between the vertical and horizontal shaft is effected by a worm upon the bottom of the former, which gears into a worm wheel on the latter. This driving arrangement obviates the noise and back-lash incident to the ordinary method. The traverse lever is made adjustable in length so as to easily yield any length of traverse as required. An improved strap fork and starting arrangement has also been introduced. This consists of a handle carrying a small pinion which is attached to the base of the fork. The latter is mounted upon a stud in such a manner as to slide backward and forward. The under part of this stud forms a rack into which the pinion gears, and thus by means of the handle the fork is traversed with ease from one pulley to the other as required. Its great merit is its adaptability to any width of pulley, and the facility with which it can be made to govern the length of the traverse of the strap. The rice creel is made of iron, and the rices are mounted
