HARRIS [37M 96%” v ATTORNEYS ~'nited States Patent 1 3,045,526 Patented July 24, 1962 2 the two standard members 20 and 21 and is preferably 3,045,526 BRAIDER CARRIER TENSION WEIGHT struck up from sheet stock so as to form a horizontal Stephen C. Harris, 1336 Warwick Neck Ave., Filed June 20, 1960, Ser. No. 37,128 2 Claims. (Cl. 87-56) plate portion 26 with the sides thereof turned down wardly to form arms 27. To provide an elongated hear ing for the weight on the standards, there is an upwardly turned portion 28 with an inturned end 29 that is pierced This invention relates to an improvement in a weight for a braider carrier. In braider carriers which are manufac in the plate portion 26. The plate portion 26 is also Warwick, R.I. , tured along the general construction lines of M-ossberg Patent 1,630,669, it has been necessary to lightly oil the vertical standards upon which the weight reciprocates. This has been necessary in order to provide free running of the weight upon the standards and it has certain deleterious effects. The presence of lubrication in gen with a hole 30 in line with a similar hole 31 pierced formed with a pair of projecting ?ngers 32 which are generally arranged to embrace the standard 21. To com plete the basic structure of the weight, a hook-shaped ?nger 33 is provided leading off the upturned portion 28 which serves as a thread guide around which the yarn is looped after passing through the eye 22. Additionally, eral upon the vertical standards acts as a place upon 15 a compression spring 34‘ is slid over the standard 20 and bears against the inturned end 29 of the weight 25 and which fly from the yarn being carried by the carrier may also against an upper bracket 35 which holds the vertical accumulate. Additionally, if rubber thread is being cov standards N and 21 in alignment at the upper end thereof. ered by the braider, the tale from handling the thread In order to provide for proper movement of the weight will fall about the vertical standards. ‘Conditions such 20 25 up and down the vertical standards 20 and 21, there as these cause the vertical standards to gum and a conse is inserted in the bearing holes 30 and 31 bushings 40 quent improper operation of the weight mechanism. As (see FIGURE 5). These bushings are cylinders with a a result of this, it has been necessary in accordance with circumferential groove 46’ and are received in the aper past practice to periodically clean the standards of the braider carrier which means that the braider must be shut 25 tures 30 and 31 in a press ?t such that the groove 40' is engaged in the holes 30 or 31. The bushings are prefer down for periods of maintenance. This is an unsatisfac ably made from polymer of tetra?uoroethylene, poly tory situation in a mill where high production is desired and it is therefore an object of the present invention to I tetra?uoroethylene, into which there has been mixed par ticles of a silicate such as mica, talc, aluminum silicate, provide a weight construction which will eliminate the or glass. This type of material is superior to pure syn need for ‘oiling the standards of a braider carrier. 30 thetic plastic materials for it has superior wear resistance A more speci?c object of the invention is to provide a weight for a braider carrier which will have one or more of the guide portions thereof provided with oilless and will not stick against a metal part as is so often the case with such items as nylon and polytetra?uoro ethylene. In practice it is found that this bushing mate With these and other objects in view, the invention con 35 rial will wipe the metal standards clean of all foreign material and thus enhances the weight operation. sists of certain novel features of construction as will be Similarly between the ?ngers 32 a U-shaped bushing more fully described and particularly pointed out in the may be ?tted. The U-shaped bushing is formed with a appended claims. peripheral groove 43 which is received between the In the accompanying drawings: ‘FIG. 1 is a side elevation showing a braider carrier of 40 ?ngers 32 in a press ?t relationship. This bushing 42 also may be made of the same type of material as the the general construction upon which the weight referred bushing 40. to may be used; It has also been found that the bushings may vary in FIG. 2 is a sectional view taken on iines 2—2 of FIG. form. For instance, a modi?ed form ‘of bushing 42’ may 1 showing one manner in which weight made in accord? ance with the teachings of this invention may be con 45 be ?tted between the ?ngers 32 (see FIG. 6).
