12 Claims.

This invention relates to improvements in cap-.

spinning and similar twisting frames. The

' present application, a division of a prior application which has issued as Patent No. 2,135,519 for High speed spindle, is more particularly directed to means for lubricating the spinning frame mechanism. Among other things, the invention provides improved means for lubricating the moving parts of the spinning frame, said means being mechanically simple, positive in operation, and of such a character as to require little or no adjustment. Other objects will appear as the description of the invention proceeds.

The increasingly high operating speeds of textile spinning frames occasions difiiculties in adequately lubricating the bearings thereof. These difiiculties the present invention overcomes by providing a reservoir formed as an integral part of the bolster and one or more pockets in the spindle itself to which lubricant is fed from the reservoir when the bolster mounted on the reciprocating lifting rail is in juxtaposition to said pockets. The relative reciprocating motion of the spindle and bolster effectively delivers lubricant to the bearing surfaces, thereby lubricating and cooling them.

The following description is directed to but one of a number of possible embodiments of the invention.

Figure 1 of the accompanying drawing illustrates a sectional elevation of a cap-spinning frame corresponding to the line II of Figure 2. I

Figure 2 is an enlarged sectional plan taken on the line 2-2 of Figure 1. Figure 3 is a sectional elevation taken on the line 3-3 of Figure 2 of the mounting of the bolster on the lifting rail with parts omitted for the sake of clearness. Figure 4 is an enlarged sectional plan taken on the line 4-4 of Figure 1 showing means for preventing relative rotation of the bolster and the spindle. Figure 5 is a sectional elevation of a brake actuating mechanism taken substantially on the line 55 of Figure 2.

Inthe drawing, in which like reference characters refer to like parts in all figures, spindle I, resiliently connected to the fixed rail 3, serves to support cap'4. Bolster 5, which is resiliently mounted on lifting rail 2, supports rotatable whirl 6, which is driven by some suitable means, as by belt I. The whirl 6 is mounted on anti-friction bearings 8 and 9. Thread bobbin, I0 is supported on the bobbin-tube II of the whirl 6 and is held in place by means of pins I2. Relative rotation of the spindle I with respect to, the bolster 5, which is adapted to slide on the spindle I, is preventedby some such means as the pin I3, in the bolster 5, which slides in a keyway I 4 in the spindle I. As shown in Figures 1 and 4 the pin I3 is held in place by means of the spring ring I5 fitting into groove I6 of the bolster.

As shown in Figures 1 and 3, one method of mounting the bolster on the rail employs a flanged portion I! on the bolster 5 which, projecting through opening 23, is constantly urged against the lifting rail 2 by means of a plurality of springs I8. These springs bear against the other side of the lifting rail 2 and against the headsof the bolts I9, inserted through holes 22 in fixed rail 2 and tapped into the flange I! and locked with jam nuts 20. A resilient washer 2| made of some material such as cork may be provided,'if desired, between the flange I1 and fixed rail 2. By adjustment of the bolts I9, the spring pressure and consequent freedom of bolster movement with respect to fixed rail 2 can be controlled as desired.

On fixed rail 3 the spindle mounting consists of a stop 24 mounted on the spindle l held against the rail by spring 25, which bears against the other side of the rail and against another stop 26 mounted on the spindle. A resilient washer 21, which may be made of some such material as leather, may be provided if desired between fixed rail 3 and the stop which bears against it. Stops'24 and 26 may be nuts, provided with jam nuts 28, as shown, for the purpose of adjustment of their axial position on the spindle shaft I. They spindle I, as shown, is non-rotatable, since it is prevented from rotating in the bolster 5, which itself is non-rotatable because it is held by bolts I9.

- In the base of the bolster 5 is a lubricant reservoir 29 which communicates by a passage 30 with the lubricant receiving pockets 3| and 32 in the spindle, more especially when the lifting rail 2 is in its uppermost position. When lifting rail 2 is in its lowermost position, the lubricant pockets 3I and 32 will be above the top edge 33 of the bolster, allowing the lubricant to run out and down over the upper bearing 8. This lubrication of the upper bearing is facilitated by the fact that the top edge-33 of the bolster, which may, if desired, be beveled, will serve to scrape off any lubricant on the spindle I as the lifting rail 2 moves upward.

After the lubricant has passed through the upper bearing 8, part of it is thrown off by centrifugal force to the inside wall 34 of thewhirl while part of it runs down the outside surface 35 of the bolster. The lubr'icant then progresses downward due to the action of gravity to the lower bearing 9 which it lubricates, passes through the bearing, and back into the reservoir 29. The lower bearing 9 is also lubricated by lubricant drawn up from the reservoir 29 by the action of the moving elements of the bearing 9 as it rotates. When lubricant pockets 3| and 32, filled with lubricant, slide within the bolster due to the relative reciprocation of the bolster and spindle, the bearing surfaces of the bolster and spindle will also be lubricated.

Complete lubrication of all moving parts in the spinning frame is thereby secured. The higher the speed at which the spinning frame operates, the better the lubrication: as the speed of rotation is increased, the action of the elements of bearing 9 in drawing lubricant from the reservoir 29 becomes more pronounced; as the speed of reciprocation is increased, more lubricant is supplied over the top of the bolster to the bearings. It can be seen that no adjustments of the lubricating apparatus are required, that such apparatus is simple, automatic and positive in operation, and that there is nothing to get out of order.

In the brake apparatus shown in Figures 2 and 5, which is provided to stop the spinning frame to change bobbins or for other reasons, the brake arms 31 and 38 are each pivoted at one end about a pivot member, such as bolt 39. The other ends of the members are provided with holes in which the pin 49 is slidably held. This pin isslidably mounted in a boss 4| in the bolster against which bear the spacing springs 42 which are supported at their outer ends in sockets 43 in members 3! and 38. One end of the pin 40 is threaded into adjusting nut 44 provided with a wedge portion 45 fitting into a corresponding depression in the member 38. This wedge portion 45 causes the member 38 to be self-adjusting with respect to the pin 40.

On the other end of the pin 40 ispivotally mounted a means of actuating the brake, such as a handle 46, which has a cam-shaped portion 41 bearing against the outer surface of the member 31 in a guiding groove 48 provided there. When the handle 46 is turned to a position such as dotted position 46', the pin 40 draws the brake arm 38 toward the whirl, while the cam 41 forces the brake arm 31 toward the whirl, and the brake apparatus takes some position as indicated by the dot-and-dash lines of Figure 2. When the brake is thus operating, the contact surfaces 49 of the brake arms, which may be of some friction-resisting material such as. leather, are forced against the whirl, bringing it to a rapid halt. When the handle 46 is returned to its "oif position, as shown in full lines, the springs 42 force the brake arms 31 and 38 away from the whirl and disengage the brake. Of course the handle 46 may be operated mechanically or by hand.

Reference may be had to the parent application of which this is a division for a more complete and detailed description of the mounting means described and shown herein.

preferred type of construction selected from among the numerous possible embodiments of the invention.
