SLUB-CATCHER AND TENSION DEVICE.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed September 5, 1911. Serial No. 647,549.

To all whom it may concern Be it known that I, CLIFTON CoRLnY, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in SlubCatchers and Tension Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in slub catchers for winding machines.

The object of the invention is to provide in a device of the character described, means for insuring the set adjustment of the tension device, and means for preventing unauthorized persons tampering with the tension device, the said latter means serving as a slub catcher.

The invention also relates to the details of construction and arrangement of parts which will be hereinafter described, and particularly pointed out in the claims.

In the drawings: Figure 1 is a perspective View of my invention. Fig. 2 is a similar view, the cap being elevated. Fig. 3 is a vertical transverse section. Fig. 4 is a cletail perspective view of the end of the bracket. Fig. 5 is a similar view of the end of the cap arm. Fig. 6 is a plan view.

The numeral 1 indicates a bracket designed to be attached to any convenient part of a winding machine. This bracket is provided with a vertical post 2, an extension 3, and a bifurcated guard member 4, the inner surfaces of the latter being beveled to permit of the free passage of the yarn. Loosely mounted on the post 2, is a slightly dished tension disk 5, and above this disk is a felt washer 6. and a helical spring 7 The upper end of the spring is bent inwardly to engage in a vertical slot 2 in the post 2. The post is provided with a plurality of notches, indicated at 8, with which a slight flange 9, formed on a milled retaining tap 10, engages whereby to hold the spring compressed to maintain an even tension on the disk. The extension 3 is formed with a vertical groove 12, and a vertical slot 13. Fitting in the groove 12, is the end of an arm 14, of a cap 15, which fits over and incloses the post and the parts associated therewith. The cap 15 is secured to the extension 3 by a bolt 16, which passes through the slot 13, and engages a threaded opening in the arm 14. By this arrangement of parts the cap member may be vertically adjusted on the bracket, and as the arm 14, fits snugly in the groove 12, the bottom edge of the cap is maintained a uniform distance above the surface of the bracket. It is highly important that this position be maintained at the bottom edge of the cap and its arm 14 forms with the disk 5 an important feature of this invention.

In operation the yarn passes between the bifurcated guards 4 then under the tension disk 5 and thence between the arm 14 and the extension 3, which form jaws as shown in Figs. 1 and 2. The yarn having been properly placed the tap 10 is forced down on the post 2 to compress the spring to exert the necessary tension on the disk 5. As the post is formed with a slot. the two legs formed thereby will readily yield sufficiently to permit of the tap 10 being forced down over the notches on the post. 'When the tap has been forced down sufficiently to compress the spring, it will be held in fixed position by reason of the flange 9 engaging in one of the notches. Hence once the tension of the spring is obtained the shaking and jarring of the machinery to which the device is applied cannot accidentally disengage the flange of the tap from its engaging notch. The tension therefore is uniform and liability of accidentally varying said tension is entirely removed. The desired tension of the device having been obtained to accommodate the particular yarn, it is now essential that the cap 15 be set so that the jaws back of it, one jaw of which is attached to it will prevent the passing of slubs of unusual size. The cap and its arm or jaw is rocked on the pivot formed by the slight pressure.

bolt, so as to cover the post 2 and the parts associated therewith. Then the cap and its jaw is raised or lowered to obtain the necessary space between the lower edge thereof and the upper surface of the extension or lower jaw 3. The desired adjustment having been made, the bolt 16 is tightened and the device is ready for use. This leaves the disk covered up by the cap but the lower surface of the cap is always enough above the upper surface of the bracket 1 to prevent it from interfering with the passage of yarn, at the same time it acts as a guide in threading up to cause the yarn to pass readily under the disk. As the yarn passes under the tension disk and the edge of the extension it is retained in a taut condition there by. When a slub on the yarn of unusual size contacts with the jaws back of the cap, the yarn will break, as usual in devices of this general type. Once the device is adjusted for yarn of a specific size, the operator can not interfere with the tension device, unless the bolt is released, and as the operator is not authorized to remove the bolt, it is obvious that a constant and uniform adjustment can be maintained, so that there will be positive assurance that all the yarn in a single order will be uniformly acted on by my improved device. When yarn of a diiferent number is to be wound, of course the cap must be removed from the post 2 and the tension device adjusted accordingly, then the cap is likewise adjusted, as previously described.

The particular construction of the adjusting means for the tension device is of considerable importance in a device of this character. By employing a split post formed with notches the flanged tap can readily be moved up or down on the post by But once the tap is adjusted the flange will hold fast in the notches and thereby prevent displacement of the parts. This arrangement will enable an operator to maintain a uniform adjustment of series of similar devices in which the same number of yarn is operated upon. That is to say if one tension device is set, and it is found that the proper adjustment occurs when the flange of the tap is fitted in any particular notch, obviously the next device can be quickly set by adjusting the tap to fit the corresponding notch in the post.

, The device is extremely simple in construction, and eflective in operation, and while I have specifically described the preferred embodiment of the improvement, many minor changes may be made without departing from the spirit and scope of the invention.

WVhat I claim is:

1. In a slub catcher, the combination of a bracket, a tension device mounted on the bracket, and a cap member having an arm forming a jaw, said cap member fitting over the-tension device and inclosing the same, the edge of the jaw and cap member being spaced from the bracket to form a passage for the yarn, the bracket and jaw forming a slub catcher.

2. In a slub catcher, the combination of a bracket, a tension device mounted on the bracket, and an adjustable cap member having an arm forming a jaw, said cap fitting over and inclosing the tension device, means for holding the cap member in adjusted position to maintain a space between the bottom edge of said cap and its jaw and the bracket to form a space for the passage of yarn, the bracket and jaw forming a slub catcher.

3. In combination, a bracket, a tension device mounted thereon including a split post formed with annular shallow notches, a disk 011 the post and bearing on the bracket, a spring on the disk, and an element formed with a flange to hold the spring under tension, the split post permitting of the flange stepping over the notched surface of said post when pressure in either direction is applied to the disk, and a cap fitting over the tension device and forming with the bracket a slub catcher.

4. In combination a bracket, a tension device mounted thereon including a split post formed with notches, a disk on the post, and bearing on the bracket, a spring on the disk, and an element formed with a flange to engage the notches to hold the spring under tension, a cap cooperating with the tension device and inclosing the same and forming with the bracket a slub catcher, and means for adjusting the cap.

5. A device of the character described comprising a bracket, a tension device on the bracket, a member surrounding the tension device and spaced from the bracket, to form a slub catcher, and means for adjusting the member.
