CHARLES D. WHITE, 01:

CARBIER-RGLL STAND Application filed July 6,

Tool! whom it away concern:

Be it known that 1, (Trustee l). l /rirrn, citizen of the United States of America, residing at Norwich, in the county of l iew London and State of Connecticut, have invented a certain new and useful improvement in ()arrier-ltoll Stands for Spinning Frames, of which the following is a full, clear, and enact description.

This invention relates to spinning frames, and more particularly to a carrier roll, stand or support for spinning frames.

An important object of the invention is to provide means for supporting the carrier roll so that the roll may be shifted trans- \ersely of its axis to remove it entirely away from the bobbin when the same has had its diameter increased materially by the thread thereon. In the form of the invention illu trated, the carrier roll is dotted by moving the same, together with its bearings entirely to one side of and wholly out of the way of the bobbins, whereby the bobbins may be freely removed.

Another important feature of the invention resides in a means for adjusting the ope 'ative position. of the carrier roll, whereby the periphery of those portions of the roll over which the thread passes is located directly in alinement with the center of each spindle.

Still another important feature of the invention is comprised in a means for adjust ably supporting the carrier roll in such inanuer that it may be moved up or down as desired, whereby its periphery will be in alinement or out of: alinemeut with the spinning delivery rolls.

The foregoing and other features of the invention including important details of construction and combinations of parts will be more fully described, hereinafter, and the novel features will be particularly pointed out in the appended claims.

upon a spindle in the usual manner, or in any approved manner and cooperating there with is the usual spinning ring and traveler.

rl bracket 5 con'iprising a flat plate portion which is secured to the vertical wall of the frame 1, and a horizontal, ireferably cylindrical portion 5, supports the bearings 7 for the carrier roll 9, a suitable number of these bearings being spaced apart along the frame to support the carrier roll. The vertical portion of the bracket 3 is provided with pa "allel longitudinal slots 38, preferably two, which receive clamping bolts 40, having polygonal. heads il, said bolts being threaded into the frame 1, and adapted to adjustably support the bracket on said frame.

The horizontal members 5 of the brackets are provided with threads 6 at their ends, and receive split adjusting collars 30, 82. The collar 32 comprises two portions, each having outwardly extending cars 34 for drawing the parts of the collars together and causing them to grip the bar 5. Between the upper pair of ears 3% a latch 81 is; pivotally supported upon the screw which unites the collars. tilaid latch is adapted to be placed in the position shown by full lines in Figure l for holding the bearing 7 in its outer, or normal position, with the carrier roll properly positioned above the centers of the bob bins Z). in this position the bearing 7 is clamped between the adjusting collar 30 and the end of the latch. When the latch is thrown upwardly and back into the position shown by dotted lines, the bearing '1? and carrier roll may be moved. rearwardly so that the roll will be entirely removed laterally from any portion of the spindles, with the maximum amount of thread wound thereon. The roll 9 may thus be moved out of the way and the bobbins readily removed by a. vertical movement upward without any interference therewith by the carrier roll.

By reason of the fact that the collars 30 and are adj ustaloly mounted upon the bar 5, it will be seen that the position of the carrier roll may be adjusted so as to insure the location of those portions of the roll over which the thread passes, directly over the axial center of the spindles. This is a very important feature of my invention as it enables me to adjust the carrier roll to a nicety with respect to the spindles.

The carrier roll is provided with a pin rality of circumferential grooves 10 which are cut into the body of the roll below its outer periphery and which serve the puipose of guides for the thread. This is very advantageous in that it provides a simple construction of guide groove, without necessita-ting the addition of any whorls, or other extraneous devices to the roll.

The usual pairs of drawing rolls, 13, 15, and the front or delivery rolls 11 are provided, and it is a feature of the invention that the thread passes in a straight line from between these pairs of rolls to the periphery of the carrier roll 9. A train of gearing, 17, 18, 19, 20, extends from the shaft of one of the front or delivery rolls 11 to the carrier roll, whereby the latter is driven. Of this train, gears 17, 18 and 19 are mounted in a gear casing 24, while the gear 20 is-mounted in a supplemental gear casing 26 having side portions which are pivotally mounted upon the shaft 28 of the gear 19. The casing 26 is provided with a handle 22 by means of which the carrier roll is moved laterally when the latch 31 is moved out of engagement with the bearing 7. In thus shifting the roll, it will be seen that the gear 520 is moved bodily to the rear with the carrier roll, and such action will cause the gear casing 24 to rise, carrying with it the gears therein, such upward movement being necessary in order that the backward movement of the carrier roll and its gear may be in a right line, as will be obvious.

It is to be observed by my invention it is possible to locate the carrier roll a considerable distahce above the top of the spindle whereby a very long bobbin may be employed, and moreover, the periphery of the carrier roll may be positioned, through the adjustment of the bracket 3,not only at a desirable distance above the bobbins, but at the same time in alinement with the thread as it passes between the pairs of draft rolls.

I claim:

1. In a spinning frame, a carrier roll adapted to be located above the bobbin, and means for shifting said roll by movement transverse to its axis to permit removal of said bobbin from the frame.

2. In a spinning frame, the combination of a carrier roll, located bet-ween the draft rolls and the bobbin, a bearing for support ing said roll, and means for moving said bearing and roll in a direction transverse of the longitudinal axis of the roll to permit removal of the bobbin.

3. In a spinning frame, the combination of a carrier roll, bearings therefor, means for slidably supporting said hearings to permit movement of the roll transverse of its axis, and means for holding said bearing and roll in normal position during the spinning operation.

4. In a spinning frame, the combination of a carrier roll located above the bobbin, :1 bearing for said roll, means to support the bearing permitting it to slide transversely of the axis of the roll, means to limit the outward movement of the bearin on its support, and locking means for holding said bearing and roll in normal position.

5. In a spinning frame, the combination of a carrier roll, a slidable bearing for said roll, means for adjusting the position of said bearing and roll transversely of its axis to aline the thread with the bobbin, said roll being IIIOXELblG laterally for dofiing.

6. In a spinning frame, the combination of a carrier roll, slidable bearings for said roll to permit lateral movement of the roll for dotiing, an adjusting nut on said hearing to limit the outward movement of said bearing, a second adjusting nut located inside of said bearing, and a pivoted latch supported by the last named adjusting nut and adapted to hold the bearing in spinning position and in engagement with the first named adjusting nut.

7. A spinning frame, having in combina' tion, a carrier roll, draft rolls, gearing between said rolls, and means for moving the carrier roll transversely of its axis for dotiing, one element of said gearing being movable relatively to the other elements of said gearing when the roll is being dofi'ed.

8. In a spinning frame, the combination of a carrier roll, bearings for said roll, and brackets for supporting the said bearings capable of vertical adjustment for positioning the carrier roll relatively to the draft rolls and the bobbin.

9. A spinning frame having, in combination, a carrier roll, draft rolls, brackets for supporting the carrier roll, said brackets provided with vertical slots and clamping means to enter said slots and adjustably clamp said brackets to the spinning frame, said parts permitting the carrier roll to be moved into or out of alinementwith the thread passing between the draft rolls.

10. A spinning frame having in combination a carrier roll, brackets for supporting the carrier roll, said brackets provided with parallel longitudinal slots which enables the carrier roll to be elevated in such a position that a longer bobbin is capable of being spun than the ordinary method of spinning.

In testimony whereof I have hereunto set my hand this 28th day of June A. I). 1922.
