RECENT PATENTS.

To JOHN SHAW, of Blackburn, in the county of Lancaster,
manager, for certain improvements in machinery or appa-
ratus for carding, drawing, slubbing, and roving cotton,
wool, and other fibrous substances.-[Sealed 14th Decem-
ber, 1846.]

THIS invention refers, firstly, to an improvement in the card-
ing-engine, whereby, in operating, the loss of so much of
the staple as is at present allowed to fly off from the licker-in
roller and main card-cylinder is prevented. This improve-
ment is effected by providing a covering to those parts of the
circumference of the licker-in roller and main cylinder which
are between the feed-rollers and the doffer-cylinder, but be-
low the line of the axes of the main card-cylinder and licker-
in roller.

In Plate I., fig. 1, represents, in section, a portion of a
carding-engine, with the improvement applied thereto. A, is
the main cylinder; B, is a curved plate or shield of metal,
supported by angular side-plates, bolted to the framing of
the engine. Fig. 2, represents, in section, one of these an-
gular side-plates, for securing the curved plate in the requi-
site position for covering a portion of the periphery of the
main card-cylinder, and yet allowing of the free action o.

that cylinder. c, is an endless band of " lattice-work," composed of laths (somewhat longer than the breadth of the main cylinder), laid parallel to each other, and attached breadthways to the outer face of an endless band of felted cloth or other suitable material; D, is one of a pair of guides, fixed to the main framing, and intended to make the lattice-work travel in a curve, so as to cover as much of that portion of the periphery of the main cylinder, desired to be enclosed, as is not covered by the curved plate в. At fig. 3, one of the guides D, is shewn, in section, with a lath or rib in contact. with its under surface. E, E, E, are rollers for supporting the lattice-work; and to the axle of one of these rollers a cog-wheel or friction-pulley is keyed, which, being put into connection with any convenient adjacent driving parts of the machinery, will communicate a forward motion to the endless lattice-work. By this means, the staple will be prevented from flying off during the working of the engine; but the dust and refuse matters will be allowed to fall between the laths on to the cloth, which carries them forward and deposits them on the floor, or into any proper receptacle.

The second part of the invention refers to an improvement in the drawing or slubbing-frames, and consists in mounting the "guider or tumbler" in such a manner that the breaking of a sliver will allow the tumbler to change its position, and thereby immediately stop the action of the machine. At fig. 4, the parts requisite for carrying out this improvement are shewn in side elevation. The sliver of cotton, wool, or other substance, in passing from the cans to the drawing-rollers, is conducted through a guide or tumbler a, attached to the upper end of a lever b, which is provided, at its lower end, with a catch c. On either side of the lever b, a projecting piece d, somewhat of the shape of an inverted V, is cast. These projecting pieces (see the front view, fig. 5,) rest upon a knife-edge, standing up from a bracket e, which is bolted to the back-plate of the machine, and is intended to support the lever b, and allow it to vibrate freely when required. g, is a weighted rocking-lever, attached to a clutch-box h, (shewn in front view at fig. 5*,) which works upon a shaft i. The lever g, is provided with a tappet k, which rides over a

cam or tappet 1, on a shaft m, connected, by gearing, with the main driving-shaft of the mechanism. At every rotation of the shaft m, it will be seen, that the lever g, will rock suddenly, and, by means of the clutch-box h, cause the shaft i, to make part of a revolution. To this shaft a "feeler" n, is fixed, and in such a position that, when moving with its shaft, it just clears the catch c, of the lever b. Now if, by the breaking of the sliver, (the tension of which, in the proper working of the machine, draws the tumbler a, sufficiently forwards to prevent the catch c, of the lever b, from interfering with the motions of the feeler n,) the lever b, is allowed to find its centre of gravity, as shewn by dots in fig. 4, the end of the feeler n, will come in contact with the catch c, and thus its vibrations will immediately cease. The rotation, however, of the shaft m, will cause the rocking of the weighted lever g, to continue; which, being connected, as before stated, with the sliding part of the clutch-box h, will cause it to slide laterally on the shaft i. To this part of the clutch-box a crank-lever o, is connected by a pin, projecting from an arm of the lever, working in a circular groove in the boss of the clutch-box. The other arm is provided with a notch, which receives the end of an arm p, fixed to a rod q. To this rod q, is also connected the forked rod, for throwing the drivingstrap from the fast to the loose pulley. When, therefore, the catch c, stops the motion of the feeler n, and, consequently, that of the shaft i, the moving part h, of the clutch-box, will be thrown off from the stationary part fixed to the shaft i, and, in sliding along the shaft i, it will cause the lever o, to vibrate, and release the arm p. If then an upward impetus is given to this arm, by a spring or weight, it will rise, and cause its shaft q, together with the forked rod (for shifting the strap), to rock, whereby the driving-strap will be slidden from the fast to the loose pulley, and the action of the machine will be suspended.

The third part of the invention refers to improvements in the roving or slubbing-flyer, employed for winding the sliver of cotton, &c., on to bobbins. The objects of this part of the invention are to prevent, in some degree, the friction of the sliver down the hollow arms of the flyer; to lay the sliver in

A 2

a compact and even state on the bobbin; and also to perform the operation with greater expedition than heretofore. These several results may be obtained either separately or combined, according to whether one or all of the improvements are adapted to the same flyer. In order to obtain the firstmentioned advantage, the hollow arms of the flyer are so formed that the longitudinal opening, produced by the edges of the metal (composing the arms) not uniting, shall be in that side of the arm which, in its rotation, meets the air, instead of being in the outside part of the flyer. The sliver will thus, when thrown by centrifugal force against that part of the inner face of the arm which is farthest from the centre of motion of the flyer, slide down a smooth surface, without the possibility of being drawn between the edges of the metal. The opening also made in the top of the arm, to allow the sliver to enter and pass down to the bobbin, is now made so as to present itself to the air whilst the flyer is rotating; by which means, if, from any cause, the sliver runs slack, it will have a tendency to remain in the tube. Fig. 6, is an elevation of the improved flyer, and fig. 7, is a plan view of the same. a, a, are the hollow arms, which carry, at their lower ends, friction-guides or arms a*, capable of turning frcely on their sockets, to allow of the increasing diameter of the bobbin; b, is the spindle; and c, the bobbin. The vertical tube d, of the flyer, which receives and is supported by the end of the spindle, has attached to it a horizontal bar e, the ends of which embrace the arms of the flyer, and keep them from expanding laterally when driven at a more than ordinary speed.

It has heretofore been considered necessary, that, to produce a firm and compact winding-on of the sliver, a considerable pressure should be laid on what is commonly called the presser-lever, which guides the sliver from the hollow arm to the bobbin; and for this purpose many plans have been devised to get, by the employment of springs, a uniform elastic pressure; but the pressure of the spring being necessarily greater on the full than the empty bobbin, it has been proposed to counter-balance this defect in the presser by means of centrifugal force, so that when the pres
