JOHN SULLIVAN, OF FALL RIVER, MASSACHUSETTS.
COMPRESSlON-ROLL FOR SLASHERS.
SPECIFICATION forming part of Letters Patent No. 578,951, dated March 16,1897.
Application filed November 17, 1896. Serial No. 612,408. (No model.)
To @ZZ whom t may concern.:
Be it known that I, JOHN SULLIVAN, of Fall River, in the county of Bristol and State of Massachusetts, have invented an Improvement in Compression Rolls for Slashers, Dressers, dto., of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
In winding yarn onto a warp-beam it is necessary that the yarn be acted upon uniformly throughout the entire length of the beam or else the tension on the individual Warpthreads when mounted in the loom Will Vary and injure the cloth.
Prior to this invention a compression-roll has had applied to it at one end a two-part extensible section, a spring contained in the extensible section causing the ends of the compression-roll to bear against the inner ends of the heads of the warp-beam. This device Works well, but the extent to which the roll may be extended in the direct-ion of its length is limited. In practice the width of the Warp Wound onto the warp-beam varies frequently, and sometimes the heads of the beam are not separated sufficiently, and in such case a beam having its heads separated for the proper distance is provided. Frequently it is desired to make adjustments of the heads on the beam, and a compressionroll having an extension such as referred to will not practically adapt itself to the new position of the heads, and a new and longer compression-roll has to be provided.
In this my invention I have improved the compression-roll referred to by combining with its open end a detachable plug having a head, said head being of greater or less thickness, according to the extra increase in length required forrthe roll over its usual limits of extension.
Figure 1 in perspective shows one end of a Slasher-frame and its Warp-beam, together with my improved compression-roll in its inoperative position; Fig. 2, an enlarged detail showing the beam with its head adj usted and the roll in working position. Fig. 3 shows the plug removed. Fig. 4 shows a plug-holder. Fig. 5 shows the roll-carrier and roll on it,
the shaft D2, to which it is attached, itsqmeight-` ed lever D3, and the journal Dtoftthwai pbeam are andpgiaymelallfas" usual.
..fllie `baifrlwlil of the Warp-beam is fixed on the journal B3, and the heads E of the beam are made adjustable on the said barrel to thus compensate for taking a Warp of greater or less width, according to the fabric to be made from the Warp. v
The compression-roll is composed of a hollow body A, having pinned to it a two-part end piece B C, the inner ends of the pieces B C being forked to interlock. A rod c is connected with the head of the part C and extended into an inner head of the part B and surrounded by a spring p to thus keep the forks of the parts B and C sufliciently separated to keep both ends of the roll pressed against the inner sides of the beam-heads.
The roll A and its two-part spring-separated end B Care the same as represent-ed by like letters in United States Patent No. 342,613, dated May 25, 1886. The springseparated end is limited in its capacity, for should the part C be moved outwardly on the part B to any appreciable extent holes are left Where t-he prongs retire from the slots, into which holes the yarn bulges and at that point is not as evenly and closely laid upon the beam. In my efforts to adapt this roll to a wider range of work I have combined with the opposite end of the roll A a removable plug ct, it being shown as a head having a shank a, the shank preferably entering a hole in a bushing b, driven or fitted closely into the hollow roll, said bushing having a head b and a pin b2, the latter entering a hole a2 in the head when the shank 0L is put into the hole in the bushing, the said pin restraining the plug from rotation. The insertion of the bushing into the open end of the roll and providing the bushing with a pin enables the employment of a hollow roll of less thickness, and therefore of lighter Weight, than were the bushing omitted.
The bushing strengthens the end of the tube, and while the pin might be inserted in IOO the end of the tube it is notzso praetieal v.or
easy of eonstruetionfasto vforeethe bushing, its hole being true, to receive -the". shank tightly into, the tube. l t
Anumber of plugs will accompanya roll, andlas the heads ofthe plugs-vary in thiekfA ness, a plug ofl the desiredthiekness :may be readily addedto the roll to adapt it'to any desired separation of beamheads and Width ofiWa-rp'toxbewvound. A A The roll having the spring-separated end section andthe plug is adaptable to any desired Width of beam. l Having described .my invention, what I claim. as new,y and desire to secure by Letters Patent, is-
F 1. A compression-roll composed of a hollow shell a spring-separated end piece at one end -fthereo and a removable plug at the other i V Y :578,951:l
a-shank, the said shank entering the hole in said'bushing leaving the head of the plug of lthe same diameter as the roll exposed at the end of the roll, it serving as a bearing-surface, substantially as described.
In testimony whereof I have signed my name to thisspeeiiieation in the presence of two subscribing Witnesses. Y
JOHN SULLIVAN.
