To alla/)hom it may concern: Be 1t known that I, ALBERT GEORG KonoH- LIN, a citizen of Switzerland, residing at Steinen, Grand Duchy of Baden, Germany,
have invented certain new and useful Improvements in Automatic Spool- Clearing Apparatus for WeftReplenishing Looms7 of which the following is a specification.
This invention relates -to automatic spool clearing apparatus for weft replenishing looms, and has for its object to provide improved means `for removing the waste yarn remaining on the spools after being discharged from the loom shuttle.
The invent-ion consists substantially in the arrangement of a rapidly revolving spindle with which the Waste yarn on the spool comes in contactand is drawn ott the spool by being coiled on the said spindle.
In the accompanying drawings which illustrate a preferred form of the inven- -tion Figure l is a side elevation partly in vertical section of the improved apparatus tted to a weft replenishing loom. Fig. 2
is a corresponding plan partly in horizont-al section; and Fig. 3 is a vertical section on the line 3-3 of Fig. l.
a is a bracket iiXed to the framing of the loom, and b is a spindle-mounted slidably and rotatably therein with its length at right angles to the loom slay c close over the shuttle box. This spindle has fixed on it a small grooved pulley driven by a cord trom amuch larger grooved pulley liXed on the main driving sha-ft d of the loom. vBy this means the spindle b is continuously rotated at a high speed. A guard plate e projecting down in front of the end of the spindleb, is carried by a rod f which is slidably mounted in the bracket a andis thus capable of being adjusted longitudinally so as to bring the plate e at the proper distance from the full spool g which lis, about to be inserted into the shuttle. The length of yarn is drawn from the spool g for threading into the shuttle, and held in some way, so that when the said spool has been inserted into the shuttle, and the loom slay is making its backward stroke, the said length of yarn will be thereby drawn under the guard plate e and thus brought into contact with the rapidly revolving spindle b whereby the said The .operation of the spindle b is not dependent 1n any way upon the manner in which the said length of vyarn hasbeen drawn from the spool and held. ln the example shown, it is assumed that the length of drawn 0H by hand and attached to an endless band '71. which is adapted to advance through a distance equal to the thickness of a spool at each change of spool.
The spool which is discharged from the shuttle, has usually some waste yarn coiled around it.. For the purpose of removing this waste yarn, there is provided a small receptacle c adapted to. receive the discharged spool as itfalls'romthe shuttle.
liap bottom n adapted to be rocked on a pivot Z by`theoperation of a shaft fm, by means of a `lever and connectingl rod as shown. The flap bottom n has a downwardslope and in thelower bottom corner of the receptacle la, there is arranged parallel to the loom slay a horizontal spindle i which is rapidly rotated by means ot' an endless cord and pulleys from the shaft d. The spindle z' is also mounted so as to be capable of being slid into and out of the receptacle Ic.
ol is a large receptacle located below the small receptacle k.
When the discharged spool falls into the receptacle c, 'it rolls on to the rapidly rotating spindle e' which engages the waste yarn projecting 'from the spool and -winds it around itself whereby the spool is entirely cleared of yarn. At the next change of spools, the iiap bottom n of the receptacle 7c to allow the cleared spool to drop out into the large receptacle o, after 'which the ila-p order to retain the spool which has just been discharged from the shuttle. This lastspool is then cleared from its waste yarn by the spindle z' and lies upon the flap bottom ready to dropout in its turn at the next shangle of spools. -The waste yarn coiled on the spindles b and vl` is removed from time to time by drawing the spindles back through their bearings, whereby the waste yarn isl pushed oill and drops into receptacles placed underneath.
The spindles b and are preferably split for the forward portion of their length in order that they may contract` when pressed arn is y Thisreceptacle has a downwardly opening Ybottom 'n is closed again immediately inis opened by the operation ofthe shaft m together in being withdrawn through their hearings, and thus allow the waste yarn to bepushed o more readily.
Having now described my invention what I claim as new and desire to secure by Let- 1. In automatic spool clearin apparatus for a weft replenishmg loom, t e combination of a receptacle having a downwardl opening lap bottom for receiving the spoo s discharged from the loom shuttle, a rapidly.
rotating spindle in said receptacle adapted rotating spindle in said receptacle adapted to coil up on itself the waste yarn on the 'discharged lspools, and means connecting said Hap bottom to the loom 'shaft that starts the changingfof the s ools, whereby just before each discharge o a .spool from the shuttle -said Hap bottom is opened to allow the cleared spool todrop out, and is closed again in time to -receive the spool about to be discharged from the shuttle,- as set forth. v
3. In automatic spool clearing apparatus for a weftreplenishing loom,- t e combination of horizontal bearings, a spindle having its forward portion split longitudinally so as to constitute resilient limbs, slidable and rotatably mounted in said bearings, and means for Withdrawin said spindle through said bearings, W ereby the waste yarn coiled on said spindle is pushed o same, as set forth.
In testimony whereof I have hereunto set my hand in presenceof two subscribing witnesses.
ALBERT GEORG KECIILIN.
