It is-an -objeoto'f 4this .invention vto reface the Agroove in the spindle :Whoi'l ito againv provide the spindle =whorl '-with a 'true fv-groove' therein.

Some of the objects of the invention having been stated, other 'objects will appear as the description proceeds when taken in connection With the accompanying drawings, in which:-

Figure 1 is a top plan View of the apparatus; Figure 2 is an elevation of the apparatus and looking at the lower side of Figure 1;

Figure 3 is an elevation of the right-hand end of Figures 1 and 2;

Figure 4 is a transverse sectional View and taken along the line 4-4 in Figure 2;

Figure 5 is an enlarged detailed sectional view of the means for holding the spindle and ejecting the same.

Referring more speoically to the drawings the ing upon the direction of rotation of member 38.

Member 32, has in the left-hand end thereof, shown in Figure 1, a cavity made to conform to the shape ofthe tip 42 of the spindle so that the tip 42 of the spindle can have rotary movement in the seat provided in the end of member 32.

Threadably secured in the base plate 10 is a bolt 60 with a lock nut 61 thereon, the upper end of this nut being adapted to serve as a rest for member 29 when in operative position.

Mounted for sliding movement on shaft 26 is a member 44 having a slot 45 in the base thereof penetrated by a screw 46 which is threadably mounted in base plate 10 for adjusting member 44 longitudinally of base plate 10.

Member 44 has

parallel portions

47 and 48 and in the upper ends'of these

portions

47 and 48 there is xedly secured a shaft 49 having a sleeve 50 rotatably mounted thereon. Rotatably mounted on sleeve 50 is a tool holder 51 having a handle 52 threadably secured therein and adapted to engage sleeve 50 when the handle is screwed home to bind the sleeve 50 and tool holder 51 together for unitary movement. This permits tool holder 51 and sleeve 50 to rotate together when the tool holder is rotated or partially rotated for presenting the tools to the whorl. When handle 52 is unscrewed, tool holder 51 can be moved longitudinally of sleeve 50 so the tools will be aligned with the groove in the whorl. Tool holder 51 has a plurality of tools removably mounted therein.

The

tools

56 and 59 inclusive, are held in tool holder 51 by any suitable means, such as set screws 56a, 57a, 58a and 59a.

The spindle whorl is provided with sloping

faces

53 and 54 and is also shown as having a groove 55 worn therein by the cord or belt used for driving the same in a textile machine and it is an object of this invention to cut down the

faces

53 and 54 to provide a groove having sloping faces terminating in a point and to cut away the portions of sidewalls or faces of 53 and 54 to provide the new groove.

Tool 56 is provided, which is not a cutting tool but when the spindle is placed in position as shown in the drawings the tool holder 51 is given a slight rotation, with handle 52 unscrewed and the tool 56 aligns and centers the tool holder with relation to the spindle whorl. After this alignment has taken place handle 40 is adjusted and the tool holder is given a slight additional rotation, and cutting tool 57 is presented to the whorl to cut away the face 54 of the whorl and the tool may be shaped so as to cut away the base portions of this face to a greater extent than the outer portions thereof. Next the tool holder is given a slight additional rotation to present cutting tool 58 to the spindle whorl to cut away the face 53 of the spindle whorl, thus causing the two faces to meet at a point in the base of the groove and thus obliterating the worn groove 55.

Next the tool holder 51 is given a slight additional rotation to present tool 59 which cuts away a portion of both

faces

53 and 54 and also the base of the groove to dress and polish the same to provide a groove having uniform sidewalls meeting at a point in the base of the groove and thus providing a new groove in the spindle whorl which, to all intents and purposes, will cause the spindle to operate as well as if a new whorl has been placed thereon.

Suitable set screws 46a and 4Gb are threadably secured in the lower portion of member 44 and the ends of these screws contact base plate 10 to hold the lower end of member 44 against the head of set screw 46. It is evident that by loosening set screw 46 and tightening set screws 46a and 46h that the upper portion of member 44 and the cutting tool secured thereon, will be adjusted to a new position with relation to the whorl.

In operation, a spindle is placed into member 15 and member 29 is swung to the position shown in Figure 3 and then handle 40 of member 38 is also swung to the position shown in Figure 3 to move the shaft 32 against the tip 42 of the spindle to hold it in position where it can be rotated while the successive aligning and cutting operations are carried out. When these are carried out and it is desired to remove the spindle from the machine for the insertion of a new spindle therein, the handle 40 is moved in a counter clock-wise direction in Figure 3 until the handle engages a portion of member 29 and then further movement of handle 40 causes the member 29 to be also rotated in a counter clock-wise direction in Figure 3 to remove the entire apparatus supported by member 29, to the dotted line position shown in Figure 3 and out of the path of a spindle while being inserted into the machine or removed from the machine. By loosening the handle 52 the tools can be aligned with the groove in the whorl, as some spindle tips 42 may have been previously ground several times, thus making this lower portion of the spindle shorter in some instances than in others.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are emr ploy-ed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. Means for reforming worn grooves in Whorls for textile spindles comprising revolving means for holding the spindle, an oscillating tool holder, an aligning tool mounted in the tool holder for aligning the whorl while it revolves, a plurality of cutting tools mounted in the tool holder and adapted to be moved successively into cutting relation with the whorl to reform the groove upon one oscillation of the tool holder.

2. Means for reforming the groove in a whorl L.:

of a textile spindle comprising revolving means for holding the spindle, pivoted means movable longitudinally of the spindle and having means for engaging the lower tip of the spindle for pressing the spindle into its holding means, an oscillating tool holder having a plurality of tools radially disposed therein and being adapted to be successively presented to the whorl upon oscillation of the tool holder to successively operate upon the whorl while it is continuously revolving.
