I 9 Claims.

This invention relates to setting frames for winding a series of yarns side by side on a receiver or spool for use in weaving Axminster and like carpets and rugs. 1

According to the present practice in winding yarns on a receiver or spool and other preparation for weaving Axminster and similar fabrics, the usual presser roll exerts pressure on the yarn wound upon the receiver or spool and is under the influence of weights and levers or springs usually connected to a sliding member which supports the presser roll, and the compactness with' which the receiver or spool is wound or the hardness of the full spool depends upon the pressure exerted by the presser roll.

When the required amount of yarn has been wound on the receiver or spool and it becomes necessary to disengage the yarn spool from the usual winding rolls, the operator must lift the presser roller by hand a distance sufficient to remove from the yarn spool the pressure of the presser roll and to provide clearance over the yarn on the receiver to swing the presser roll forward or to one side. Likewise, if it is desired at any time to insert or engage an empty receiver or spool when the presser roll is down in working position,

the operator must again lift the presser roll by hand the full distance of the vertical lift or movement of the presser roll. 1

' One of the objects of the present invention is to provide means to eliminate the labor fatigue of the operator in lifting the presser roll as described.

In accordance with the present invention mechanically operated power means is connected to the presser roll and is rendered'operative at desired times to raise the presser roll from its contact with the wound yarn upon the receiver or spool, and since when a required amount of yarn has been wound upon the receiver and the receiver and its load are to be removed from the setting frame, the present invention provides for the automatic operation of the power means to raise the presser roll to provide a clearance between it and the yarn laid on the receiver such that the presser roll may beswung from its normal operative position to one side or frontwardly.

In accordance with another feature of the invention the power actuated means for raising the presser roll at any time desired is under the control of the machine attendant who may set the power means in operation.

The invention and novel features thereof will best be made clear from the following descrip- Fig. 1 is a side elevation of onev type of Ax- I minster setting frame containing the present invention, certain parts of the setting frame being omitted for clearness of illustration; and

Fig. 2 is a front view of the setting frame, with some of the parts broken away and taken at right angles to the view shown by-Fig. ,1.

The frame I of the machine may be of any convenient and appropriate character for supporting the operating parts, and mounted in suitable bearings on the machine frame is the main drive shaft 2 on which is loosely mounted the clutch pulley 3, Fig. 2, which may be driven from any suitable source of power by a transmitting power connection, such as a belt 4, Fig. 1.

In setting frames of thetype shown, the winding mechanism or rolls for rotating the receiver arev actuated from the main drive shaft when it is clutched to the clutch pulley 3 which is driven continuously, but since the transmitting mechanism between the main drive shaft and the winding rolls is well known and the details whereof form no essential part of the present invention, such transmitting mechanism is not herein illustrated. Mounted in suitable bearings at the top portion of the machine frame are the winding rolls 5 and 6, between which the yarn receiver or: spool l is supported and operated, it being understood, of course, that the series of yarns, as usual, are taken from appropriate sources of supply and led'to the receiver '1.

Mounted in guide ways 8 on the machine frame are the presser roll supporting slides 9, one at each side of the machine, and on the upper portion thereof the presser roll is mounted, and in order that the presser roll may be turned from thepositionq: to the position y, as indicated in Fig. 1, the supporting slides 9 are made in two parts connected pivotally at H, the construction being. such that when thevpresser roll has been raised a sufficient distance to providea clearance between it and the .mass of yarn wound upon the receiver, the presser roll may be moved from the position at to the position 1 by hand, as usual, whereupon the wound receiver or spool may be removed from the setting frame.

Mounted in suitable bearings 12 is the presser roll lifting shaft !3 which extends transversely of themachine frame and at its opposite ends has secured thereto arms- I 4 which are themselves connected at each side of the'machine by the rods it to the slides 9, as at l5, which support the presser roll, the result being that should the shaft is be turned the slides 9 and the presser roll mounted thereon may be raised the required amount desired.

Connected for rotative movement with the clutch pulley 3 is a sprocket wheel I5 which is connected by the sprocket chain I! to a sprocket 5S loosely mounted on the presser roll lifting shaft i3. Associated with the sprocket wheel 59 is a roll lifting clutch I9, which may be-of usual construction and, as shown, is of the J ohnson jaw clutch type.

Pivotally mounted at 20 on the standards 2| is the yoke 22, the pins 23 of which enter appropriate grooves in the clutch l9, and associated with the yoke 22 is the treadle 24, whereby the shifting movement of the clutch may be imparted to it by the machine attendant at appropriate times or when desired.

Operatively connected with the Johnson clutch is a sprocket wheel 25 which is connected by asprocket chain 25 to a sprocket wheel 2! on the cam shaft 28, Fig. 2, the construction being such that upon operation of the sprocket wheel 25 through the clutch IS the cam shaft 28 will be rotated.

t will be noted from Fig. 2 that the treadle mechanism may be operated at any time by the machine attendant and when it is in its upper position shown by full lines in Fig. 2, the clutch i9 is rendered inoperative, but when in dotted line or lower position, as indicated in Fig. 2, the clutch members are engaged and motion will be transmitted to the cam shaft, as described.

The cam shaft 28 carries at each end a presser roll lifting cam 29 which is operatively associated with pins or rolls 39, one on each of the presser roll slides 9, the construction being such that when the cam shaft 28 is rotated the presser roll lifting cams 29 will lift the presser roll from engagement with the yarn laid on the receiver.

From the construction thus far described it will be apparent that the operation of the cam shaft 23 and the lifting movement of the presser roll are under control of the machine attendant by manipulation of the treadle 24 whichmay be operated at any time during the winding operation when it is desired to lift the presser roll by power. 7

As here'inbefore intimated, one of the important features of the present invention consists in automatically lifting the presser roll by mechanical power when a predetermined amount of yarn has been wound upon the receiver, and as a conventional and well known form of means for determining the amount of yarn placed upon the receiver and causing the winding operation to be stopped, the yarns which are to be wound upon the receiver pass between the measuring rolls 3i and 32, and when the requisite amount of yarn has been wound upon the receiver the stop arm 33 is lifted about its pivotal connection 34, but since the measuring and winding stop motion is of well known construction and operation further details thereof appear unnecessary.

Connected to the stop arm 33 is a transmitter 35 which is connected to the clutch mechanism on the main drive shaft whereby the winding operation is stopped when the requisite amount of yarn has been wound upon the receiver, and since such mechanism and stopping means are of the conventional type and well understood by those skilled in the art further elucidation of this feature appears unnecessary.

Connected to the stop arm 33 is a link 36 which at its lower end is connected with a short rm 3! of a lever 38 pivotally mounted on the machine frame at 39. The longer arm of the lever 38 is connected to a link 49, the lower end of which is connected to a rod 4| pivotally associated at 42 with the clutch controlling lever 43, the result being that when the stop arm 33 is raised, as hereinbefore described, and when the requisite amount of yarn has been wound upon the receiver the rod 4| will be depressed through the lever 38, link 4|! and the connection 49, and thereby cause the clutch H) to become operative to turn the cam shaft 29, as hereinbefore noted. The presser roll lifting cams 29 will thereupon raise the presser roll and provide a clearance between it and the yarn on the receiver,

The present invention also provides for stopping the operation of the lifting cams 29 when the presser roll has been raised to the maximum amount desired and to this end the rod 4| is provided with a slot 45 at its upper end which engages the pin 46 carried by an arm 4'! secured to one of the slides 9 which support the presser roll.

As the winding operation proceeds the amount of yarn on the receiver gradually increases in amount and, of course, raises the presser roll while the latter still bears upon the yarn, and

when the power actuated means has lifted the presser roll the desired amount to" provide clearance between it and the yarn on the receiver, the pin 46 will rise in the slot 45 to the dotted line position, Fig. 2, thereby acting upon the clutch shaft lever 43 to throw the clutch |9 out of operation with the presser roll raised to its upper limit.

It may be desirable at times to operate the presser roll lifting cams 29 during the winding operation by turning the cams under hand power and to this end the cam shaft 28 is provided with a sprocket wheel 48 about which passes the sprocket chain 49. The sprocket chain 49 likewise passes about a sprocket 59 mounted upon the machine frame and capable of actuation by the hand crank 5|. It will be recalled that during the winding operation the power actuated means for lifting the presser roll I!) is out of action, that is the clutch i9 is disengaged from its companion member, so that it is possible to turn the presser roll lifting cams 29 by the hand means described at any time during the machine operation.

The crank arm 5| is preferably mounted upon an axis 52 while the sprocket wheel 59 may be selectively engaged with the crank arm by means of a clutch 53 against the stress of a light spring 54. This enables the crank arm 5| to remain idle until intentionally clutched to the sprocket 59, so that during the winding operation or the power actuation of the presser roll lifting means the crank arm remains idle.

' Thus it will be seen that the present invention provides mechanicalpower means for raising the presser roll and provide a clearance between it and the yarn on the receiver, when the amount of yarn on the receiver has reached the desired-condition, and it will be likewise noted that the machine attendant may at any time throw the power means into operation for lifting the presser roll. Furthermore, the'presser roll lifting cams may be actuated by hand at any time during the winding operation while the power means for lifting the presser roll is inoperative.
