The upon the axle of the pulley 15. From this last mentioned pulley, a strap extends through a guide to the going in scroll o. This going in scroll has upon its axle both a fast and loose pulley, and the bearing bar r, in falling strikes a lever which causes the strap to be shifted from the loose to the fast pulley, when the going in scroll is immediately made to revolve, and the 'band n, to traverse the reverse way to that previously described, which draws the carriage towards the left hand. "At this time, also a pendant lever 16, carrying two friction pullies is allowed to fall against the loose vertical strap 17, extending from a pulley on the axle of 14, down to another pulley on the axle of the drum band pulley d. weight of this lever causes the strap 17, to become tight, and consequently by its friction now to turn the pulley d, and its axle, and to traverse the band e, by which the drums and spindles are made to revolve, for the purpose of winding the threads upon the cops. The weight with which the pendant lever falls against the loose vertical strap 17, must be such that if the yarns pull too tightly, the strap shall be enabled to slip round upon the pulley, else the yarns would be wound too tight, and perhaps break. When the carriage has ran in, a pin on its side strikes a lever that shifts the strap again on to the loose pulley of the going in scroll, and stops the carriage, and by similar means, the pendant lever 16, is thrown back and the tension of the vertical strap 17, removed. The roller 7, at the lower end of the faller lever, having as the carriage advanced, traversed along the top of the copping rail 9, now falls down into the situation shewn in the figure, raising the faller wire 6, above the tops of the spindles, and the strap b, having been conducted on to the fast pulley a, as in the former instance, the carriage is again run out, and the drawing, stretching, and VOL. XIII. 2 T spinning of the yarns, performed again exactly in the manner above described. Such is the general construction and operation of this ingenious combination of machinery, some of the minutiae of which we have been compelled to omit in our description. We have recently seen several of the above mules in operation, and the work which has been produced by them, we have no hesitation in asserting to be equal to, if not exceeding, both in quality and expedition, the productions of the most competent spinners, and that the cops formed are very much superior in shape, to those wound in the ordinary way by hand. To HENRY CHARLES LACEY, of Manchester, in the THIS invention is a newly contrived spring to be attached to carriages, for the purpose of affording an elastic bearing to the body of the carriage, without allowing it to swing so much in a lateral direction as carriage bodies generally do when suspended upon grass-hopper springs, or such other springs as are commonly employed for that purpose.... The springs proposed by the patentee are to be made of steel, wire, or rods coiled into a helical figure; or a number of elliptical segments of steel combined together; or under some circumstances caoutchouc (Indian rubber) cut into cubes. The various modes of adapting which several kinds of springs will be understood by reference to the figures in Plate XIII. Fig. 1, represents a side view of a stage coach with the improved springs adapted thereto, and fig. 2, is a' back' view of the same, shewing more perfectly the manner of attaching the springs to the carriage, and suspending the body. The remaining figures 3 to 9, exhibit the several modifications of the invention, or different modes of constructing the springs, which are here drawn upon a larger scale, the boxes that enclose them being cut in section to exhibit the parts within. Fig. 3, is a section of a cylindrical box a, a, containing one or more helical springs; b, is the base plate or bottom of the box made of metal, the cylinder and its bottom being attached together, by screwing, soldering or any other convenient and ordinary mode of connection, and which box is made fast to the rail of the carriage, by bolts or other fastenings; c, is the helical spring made of welltempered steel, and of a strength suited to the load, that it is intended to bear, which would be known to any experienced workman; d, is another helical spring within the former, intended to increase the strength of the support, and which is recommended to be twisted in an opposite direction to the former, in order to prevent their entangling There might be a third, and fourth spring within these for the purpose of affording increased support, and for stage coaches it is recommended that four springs be introduced; e, is a circular plate or disc, nearly fitting the interior of the cylinder, and bearing upon the top of the spring or springs; which plate is to be made of gun metal. Through the centre of the base plate of the cylindrical box, a pillar. f, f, is passed, which is |
