SPINNING-MACHINE.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed November 21, 1913. Serial No. 802,232.

To all whom it may concern:

Be it known that I, ARTHUR L. SCHOELLES, a citizen of the United States, residing at Newfane, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Spinning- Machines, of which the following is a specification, reference being had to the accompanying drawings. i

This invention comprehends certain new and useful improvements in spinning machines and relates more specifically to that type known as spinning mules and has for its primary object to provide means which may be incorporated in a spinning mule for catching and holding the end of the yarn during the operation of removing a full bobbin and replacing the same by an empty bobbin, thereby preventing the yarn from winding around the spindle.

Another object is to provide a device of this character which may be employed upon spinning machines of the type now in general use at a comparatively small cost without the necessity of altering the construction of said spinning machines.

A further object is to provide a device of this character which will be composed of a comparatively small number of parts of simple formation and which, when applied, will be highly efficient and effective in use.

With the above and other objects in view, my invention consists in certain novel constructions, combinations, and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which,

Figure 1 is an elevational view of my invention applied to a spinning mule of ordinary form, a portion of said mule being shown in order that the invention may be more readily understood. Fig. 2is a view similar to Fig. 1, showing my invention in use: Fig. 3 is a vertical section through a portion of my invention with a spindle upon which this portion of the invention is applied, shown in elevation; Fig. 4 is a crosssectional view through the spindle with the parts of my invention mounted thereon shown in plan; Fig. 5 is a detail plan view partly in section showing a slightly modified form of the invention; Fig. 6 is an elevational view of the modified form of clamping disk; and Fi 7 is a transverse section through the roe? shaft, showing in elevation, a modified form of up orting bracket for said shaft.

Referring more specifically to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 designates a portion of the frame-work of a spinning mule carrying the usual rigid arms 2 at each end, one of which is illustrated in the accompanying drawing. The usual yarn guiding arms 3 are carried by the shafts 4:, each of which has one end mounted in one of the rigid arms 2. It will be understood that a pair of guiding arms 3 is provided for each spindle 5, said spindles being mounted in the frame-work of the spinning mule and rotated in the-usual manner. of clearness, I have shown only one spindle with a bobbin (5 mounted thereon, in order that I may clearly show my invention and the manner in whichit is connected with the above mentioned parts of an ordinary spinning mule.

My invention as herein disclosed consists of a wheel 7 provided with radially directed fingers or arms 8 and adapted for frictional engagement upon the spindle 5' immediately beneath the bobbin 6. I have also provided a disk 9 loosely mounted upon the spindle 5 below the wheel 7 and adapted for cotiperation with the same. The disk 9 is provided with the depending tubular stem 10 which has an,annular flange 11 at its lower end. The purpose of this construction will presently appear.

The lower or flanged e'nd'of the stem 10 rests upon the bearing balls 12 in the cup 13 which is slidably mounted upon the spindle 5 and resiliently retained in its up permost position by a helical spring 14: which has its lower end rigidly-secured to t'he portions of the frame-work 1, through which the spindle 5 is mounted, as shown at 1'5.

The disk 9 is forced downwardly by means of the bifurcated arm 16 engaged around the stem 10 and bearing upon the flange 11, said bifurcated arm 11 being mounted upon the rod 17 carried by the collar 18 which is adjustably secured upon the shaft 19, by means of a set screw 20 .or the like. Each end of the shaft 19 is rigidly mounted within an arm 21 which is adjustably secured to the stationary arm 2, as shown at 22, and preferably extended in a horizontal direction toward the spindle 5, whereby the height of the shaft 19 may be readily adjusted, as desired.

The shaft. 19 is rotated by a lever 23 se For the sake 34, and adapted,

. turned to and locked to eliminate all danger cured upon the same, as shown at 24, and carrying a locking dog 25 for engagement bet-ween the notches 26 in one longitudinal edge of the outwardly directed rack arm 27 of the plate 28 secured to a portion of the frame-work 1, as shown at 29. It will be understood that the locking dog 25 is 1 slida bly'mounted upon the lever 23 and is resiliently retained in operative position by the helical spring 30 around the guide rod 31 which has one end connected with the locking dog 25 whileits opposite end is extended through the guide bearing 32 on the lever, the last mentioned end of the rod 31 ing securedto thereleasing finger 33, which latter is pivoted to the lever 23 adjacent the handle end thereof, as shown at when pressed toward the handle end of the lever 23, to withdraw the locking dog 25 from between the notches 26 of the rock arm 27.

The locking dog 25 is normally engaged in the uppermost notch 26 of the rack arm 27, thereby causing the bifurcated arm 16 to retain the disk 9 in spaced relation with the wheel 7. When the proper amount of yarn 28 has been wound around the spindle 5, the arms 3 are swung downwardly as shown in Fig. 2, as the carriage or movable part of the mul spindle 5 given a half turn, thereby causing one of the arms 8 of the wheel 7 to catch the yarn 28 and spindle. The outer end of the lever 23 is then moved to and locked in its lowermost position, thereby raising the bifurcated arm 16 and allowing the spring 14 to force the cup 13 and disk 9 upwardly, pressing said disk against theyarn and gripping the same between said disk 9 and the wheel 7.' The bobbin 6 is then removed and an empty bobbin placed inposition, after which the arms 3 are again returned to normal position and the spindle turned to wind the yarn on the new bobbin. The movable portion or carriage of the mule is then run in aboutsix feet, the disk 9 rotating upon the bearing balls 12 with the wheel 7 and spindle 5. As soon as a sufficient amount of yarn has been wound upon the bobbin of the yarn slipping from said bobbin, the lever 23 is again rein its uppermost posit-ion, thereby drawing the disk 9 from the wheel 7 and allowing the end of the yarn to fly upwardly.

From the foregoing, it will be readily seen that I. have provided improved and novel means for taking care of the yarn durihg operation of removing a filled bobbin and placing in position an empty bobbin and it will be seen that the parts of my invention are so constructed and arranged 0 091 of this patent may be obtained for flv'e cents each, by addressing the a losss of yarn each slightly modified form e moves outwardly, andthe,

draw the same close to the as to eliminate all danger of the yarn winding around the spindle and thereby causing time the bobbins are changed. It will therefore be seen that this device will. not only save time, but will also save a quantity of yarn heretofore wasted.

In Figs. 5, 6 and 7, I have shown'a of the invention in of the disk 9' has a pair of spaced flanges 11 in its opposite ends and the bifurcated arm 16 is formed integral withthe' rod 17 projectingfrom the collar 18 adapted to be secured-upon the shaft 19, by the set screw 20' or other suit able securing means. The outer parallel ends of the bifurcated arm 16 areprovided with alined transverse openings 35 to receive the laterally projecting pins 36 of the which the stem- 10 segmental blocks 57 for closing the outer after the same has-been stem 10 of the disk 9. In this modified form, I have also shown a slightly different form of bracket arm 21 having a horizontal portion 38 with an enlarged apertured bearing end 39 to receive the shaft 19. while the vertical portion 40 of said bracket arm 21 is suitably perforated whereby the same may be secured to the frame l of the movable portion of the end of said arm 16 engaged around the spinning mule and secured to the rigid arm 2 as in the preferred form. t will be understood that other minor changes inthe details of construction and arrangement of parts maybe made within the scope'of the appended claim without departing from the spirit of my invention or sacrificing any of. the advantages of the same.

What I claim is:

I In a machine of the character set forth, the combination with a rail and a, spindle carried thereby, .of a thread holding-jaw fixed thereto, a second jaw freely carried thereby and capable of movementendwise thereof relativelyto-the fixed jaw, a member loosely surrounding the spindleand coacting with the movable jaw formaintainving the jaws normally closed, a spring in terposed between the member and rail and having its extremities secured thereto. means operatively engaged with the movable jaw for separating the same from the fixed jaw against the tension of the springcontrolled member without stopping the spindle, and anti-friction means interposed between the movable controlled member. v

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
