Abstract: 16,816. Coats, E. S., and Watson, T. Sept. 21. Flyer frames for spinning and doubling cotton &c. The flyer is driven by a band, and drags round the spindle against the action of a brake. It consists of a tube 1, carrying a wharl 12 and rotating on the inner wall of an oil cup 6, which may be divided into separate chambers by a perforated partition 7. The wharl serves as a cover for the cup and has downwardly-projecting ribs 10, 11. The cylindrical surface on which the flyer rotates is grooved to facilitate lubrication. The flyer carries on its upper edge a fixed guide 16 and a movable guide 19, the latter being formed of the hooked end of a pivoted and balanced lever 18 : 26, 26 are anti-ballooning plates, and 22 is a spring brake for the purpose of stopping the flyer. The upper part of the flyer, carrying the thread guides, may be made separate from the body, and be rotated by friction thereon. The spindle 3, Fig. 15, is supported in a footstep 30 in a tube 31, which fits loosely in an outer tube 28. It is provided with a hood 38, above which projects a holding-down hook 41. The tube 31 is prevented from rotating with the spindle by a pin and slot arrangement, and suitable slots and apertures are provided for lubricating purposes. Against the side of the hood 38 presses the brake, which is mounted on the upper end of the lever 133, 135, and is pressed against the spindle with a force which is automatically increased as the cops increase in diameter, and also when the machine is stopped, in order to prevent over-running of the spindles. The lower ends 135 of the brake levers are pressed outwards by wedgeshaped blocks 136, which are carried by a bar 137, moved automatically during the spinning operation by connection with the building-motion, and also suddenly by connection with the strap fork when the machine is stopped. The spindle rail is reciprocated for the building of the cops, the extent of the traverse being automatically reduced as the winding proceeds, in order to wind the cops with conical ends. The rail is raised and lowered by chains &c. from a reciprocating shaft 56, which is rotated in opposite directions alternately, through the 'arrangement of three bevel-wheels 46, 47, 48, the wheels 47, 48 being caused to gear alternately with the constantly-rotating wheel 46 by the movement of the clutch or change levers 71. For the reversal of the lever 71, adjustable spring stops 105, carried by right and left handed screws 115, 116 on a vertical spindle 112 carried by the rising and pulling rail, are caused to operate a bell-crank lever 100, the spindle 112 carrying also a ratchet arrangement 124, which at each reciprocation of the rail is operated by an inclined projection 160 on the frame, so as to adjust the distance between the stops 105 automatically, and shorten the traverse as the winding proceeds. The lever 71, Fig. 9, is locked in its extreme positions by a vertically-sliding stop 92 and a notched stop-pin 95 ; and the bell-crank lever 100 is locked in its extreme positions by the bevelled extremity of a spring plate 81, which engages with the correspondingly-shaped extremity of the bell-crank lever. The plate 81 and stop plate 92 are connected together by pins and slots, so that when the plate 81 has been raised sufficiently, the plate 92 is raised with it. The first effect of the movement of the bell-crank lever 100 by the stops 105 is to raise the spring plate 81 until the stop plate 92 is raised, and the projection 73 on the lever 71 released ; then the lever 100 engages with a second projection 79 on the lever 71, and begins the movement of the lever 71, which is continued until the parts have been moved sufficiently to allow the spring plate 81 to move the parts fully into their other extreme position, in which they are locked as before by the stop plate 92 and notched spring stop-pin 95.
