Title: Improvements in apparatus for use in the preparation of textile strands
IPC: D01G99/00
Filed: 1930-02-06
Abstract: 340,837. Balling slivers ; gill-boxes. ABBOTT, E. J., Wilton, New Hampshire, U.S.A. Feb. 6, 1930, No. 4087. [Class 120 (i).] In apparatus in which slivers or other strands are cross wound without twist upon a perforated core which is subjected to a uniform tension to form a compact, uniformly dense and porous, selfsustaining package capable of retaining its shape when standing on end in a wet condition, a reciprocating carriage for the drum and winding mass is provided with movable supports having trunnions engageable with opposite ends respectively of a spool having a hollow perforated barrel and fixed heads as used in pressure dyeing. The barrel is of such length that the heads of the spool overlap the ends of the drum and the winding mass contacts at all times with the drum to insure a uniform winding speed. The trunnions are adjustable axially for the insertion and removal of the spool. Rolls 4 draw slivers S through pot-holes 9 in a board 8 to fallers 6 of a gill box and front rolls 5 take the parallelized fibres at greater speed to one or more trumpets 15 mounted in trunnions 14 on a bracket 13 on the machine framing, pulleys 18 on the trumpets 15 being encircled by cords secured around a carriage 30 reciprocation of which oscillates the trumpets. To reciprocate the carriage, a rack 35 thereon is engaged by a pinion 36 rotated intermittently by a mangle wheel 40 and the carriage moves along a fixed bar 29 and spindle 21. The sliver guide in the trumpet has eccentric walls which transmit the oscillations of the trumpet to the sliver and so neutralize any twist due to the traversing movement of the carriage, splined on which between the end frames 31 thereof is a drum 24. A perforated core 66 on which the slivers are wound rests on the drum and is rotated by it. Trunnions comprising short shafts 59, Fig. 7, carry the core by means of plates 60 having inwardly directed flanges 62 engaging within the core and radial flanges 63, the arms 59 being rotatable in bearings 58 by arms 64 which move in cam slots to permit withdrawal of the plates 60 from the core. The bearings 58 are mounted in arms 50, Fig. 5, pivoted at 49 to brackets on the carriage 30 and drawn downwards by spring- influenced links 52 to press the winding mass on to the drum 24, the springs acting with progressively decreasing leverage as the winding package increases in size, a constant pressure between the winding mass and the drum being thus obtained. The drum 24 is driven from the lower front roller 5 and is geared to a shaft 44 which drives the mangle wheel 40 and reciprocates the carriage 30. The movements of the carriage are small and permit several slivers to be cross wound on one core side by side simultaneously without any sliver overlapping its neighbours.

Abstract: 182,740. Vogt, H. C., Boby, W. V., Lancaster, S. D., and Kroyer, S. Feb. 11, 1922. Screw motors; regulating.-A windmill with flexible sails is provided with means for adjusting the position of the sails round their masts, the position of the rotary mill tower relative to the direction of the wind being adjusted automatically without the use of tail vanes. The sails 10 are carried on four masts 1, and are stretched by rigid sprits 12 and two or three horizontal flexible spars 13. Guy ropes 17 secure the masts relativelv to each other, and secure them in sockets 2, Fig. 3, in a sleeve 3 mounted in bearings 4, 5, 6, Fig. 1, carried on a platform 7, which is rotatable on a ball-race 8. The sails are simultaneously tightened or slackened by tackle comprising cables 31, 27, springs 33, 29 and pulleys 32, 30 connected to a screwed nut 18 mounted on a screw 19 within the sleeve 3, Fig. 3. The screw is connected by a square end to a sprocket wheel 22, on which a chain 23 runs to a hand-wheel 24. Normally the sleeve 3, nut 18, screw 19 and sprocket wheels 22, 24 rotate together as the windmill is working, but if it is desired to tighten the sails, the hand-wheel 24 is temporarily held to stop the sprocket wheel 22 and the screw 19. The sleeve 3 and nut 18 in engagement therewith continue rotation, and the nut 18 moves along the screw 19 to the right, so tightening the sails through the cable and pulley tackle. To slacken the sails the handwheel 24 is rotated faster in its normal direction. The screw 19, nut 18 and sprocket wheels 22, 24 may be dispensed with, and may be replaced by a block sliding in the sleeve 3. The cable and pulley sail-tightening tackle are then connected to the block, which is also connected by a cable passing through the sleeve 3 to a pivoted weighted quadrant to obtain uniform tension on the sails. Toothed wheel and belt and pulley multiplying-gearing may be provided for driving a dynamo from the sleeve 3.

Filed: 1918-03-09
Abstract: 114,307. Ott, J. Klaus-. March 10, 1917, [Convention date]. Variable-speed toothed and chain gearing.-In gearing of the axially-sliding wheel type, the wheels are formed in two or more sector-like parts which are moved successively into engaging position; in the case of chain-gearing, one chain only is needed for all the change-speed wheels. Figs. 1 and 4 shows a toothed gear in which a driving-shaft 1 drives through gearing 2 a shaft 3 which carries, on a non-circular part of its length, gear-wheels 5<1> - - 5<4> formed in two parts and integral with half-sleeves 4. The wheels 5<1> - - 5<4> are arranged to gear with wheels 6<1> - - 6<4> on a shaft 7, giving four speeds which are conveyed to the driven shaft 10 by a clutch 8, 9. A reverse is obtained by the use of a gear 14 on the shaft 3, an idle wheel 15, and a gear 16 integral with the clutch part 9. Each of the halfsleeves 4 carries a lug 18 passing through a slot 39 in the inclined cheek's 42 of a block 38 which slides parallel to the shaft 3 in a guide 41 and carries a pin 37 engaging a cam slot in a drum 30 which carries tappets 27, 28, 29, and a pinion 35 gearing with a pinion 36 on a spindle 25 carrying tappets 32, 33, 34. For changing speed, tappets 22, 23 on a sleeve 19 turning with the shaft 3 are adjusted axially to engage the appropriate tappet on the spindle 25 or drum 30, so that the drum is turned and the block 38 moved along its guide 41. During the rotation of the shaft 3, the lug 18 on the half-sleeve which is at the moment just out of driving engagement with a wheel on the shaft 7 strikes one inclined cheek of the block 38 and slides one half gear-wheel into the plane of the next gear-wheel on the shaft 7. Half a revolution later, the other half-sleeve is moved axially, by which time the first half wheel has rotated into position to begin the transmission of power at the next speed. In the chain gear shown in Figs. 13 and 16, the shaft 45 is driven from the driving-shaft 43 and turns with one complete chain-wheel 46<1>, further wheels 46<2>, 46<3>, 46<4> being formed on a sleeve 49 turning with the shaft and formed in six parts. A chain 63 conveys power to a similar series 59<1>, 59<2>, 59<3> formed in six parts or to a complete wheel 59<4>, all turning with a shaft 54. A driven shaft 65 may be clutched to the shaft 54 for forward speeds or driven by gearing 68, 67, 66 for reverse. In this form each of the sleeve parts carries a lug 53 or 58 engaging successively with sliding blocks 91 or 90, both of which engage a cam-groove in a drum 84. Rotation of the drum is produced by tappets 80, 72 on the shafts 54, 45, respectively, engaging tappets on the drum 84 and on a geared spindle 77, each of the tappets 80, 72 having two teeth rotate the drum 84 in two stages, so that the wheel sections on one shaft are moved before those on the other. Additional guides 50, 60 with annular grooves are provided for the lugs 53, 58.
