116&#93; [ii6 spr either by iftMns of a whcftl, or sometimes with a distalF and spin- dle: but, as ll:e wheels commonly employed tor this purpose, are aukward and incoru'enient, Mr. Antis, of F'ulneck, near Leeds, in 1793, submitted to the inspeftion of the Society for the Encourage- ment of Aits,8cc. a model of an im- proved spinning-wheel ; for which they conferred on him a bounty of 20 guineas. — ^Ve have, therefore, proL:ured an engraving- of this use- ful domestic machine, for the be- hetit of our country readers. jDescripiion of the Plate repre- senfing jVIr. Antis's Improved . Spinning'lVheel. The usual method of stopping tbe wheel, with a view to remove the yam from one staple on the flyer to another, necessarily occa- sions great loss of time; but, in Mr. A.'s contrivance, the bobbin is so arranged, as to pass backward and forward, in order to prevent any interraption ; and at the same time to obviate botb the breaking of the thread, and losing the end : hencft, the spinner is enabled to perform more work, in a given time, tlian is practicable by any other spinning-wheel. Such objeft is etteded, by extending tiie axis of the great whed through the pil- laf next the person spinning j ami forming it into a pinion of one leaf, A ; which catches into a wheel, B, seven inches in dianieter, having on its periphery 97 teeth ; so that 97 revolutions of the great wheel require only one of the smaller wheel. On the latter, a wire-ring, ■ c, c, c, is fixed ; which, b"ing sup- ported on six legs, stands obliquely 10 the wheel itself; toucning it at one part, and projeiting nearly three-quarters of an inch at the SPI opposite edge. Near the side of this wheel, is an upright lever, C, about 15 inches in length, moving on a centre, three inches from its lower extremity, and conne6ted at the top with a sliding bar, D. From such bar rises an upright piece of brass, E ; which works in the notch of a pulley, and drives the bobbin F,to and fro, accordingly as the oblicjue wire forces the pin G, in or out, during the revolution of thf wlieel. In order to regulate and assist the alternate motion, a weight, H, is suspendedby alinefrom the slid- ing-bar ; and, passing over a pulley I, it rises or falls, as the bobbin ad- vances or recedes ; tending con- ."stantly to keep the pin in conta6l with the wire. In consequence of this construftion, the flyer requires only one staple ; which, being fixed near the extremity K, the thread entering through, is regularly laid on the bobbin, by the rotary motion of the latter. Since Mr. Ant is presented the model of the machine here describ- ed, he has made several alterations, which greatly contribute to its per^ fe6tion; and for which the Society, in 1795, rewarded him with the additional sum of 15 guineas. As w^e conceive, that an account oi tlrese improvements will be inte- resting to every industrious house- wife, we shall concisely state them, together with Mr. A.'s remarks. 1. At every revolution of the wh'^el, in his former machine, the pinion WTth one leaf occasioned a very disagreeable catch, while the bobbin moved only by jVrA's, and did not receive the thread in an uniform manner. With a view to remedy this inconvenience, Mr. ANTishas adoptedthe motion of an endless screw, working a toothed wheel.
