(Cl. 28-38) V Claims.

This invention relates to a compressor roll for a Warp compressor or other textile machine in which warp or yarn is wound upon a beam having heads by rotation of the beam. It is the object of the invention to provide such a compressor roll which shall be capable of adjustment to any length of beam, and it is the further object to provide such a compressor roll which shall be automatically and yieldingly extensible so that its ends shall remain in contact with the beam heads during the winding operation thus toextend over the entire length of the warp mass and inwhich the cylindrical surface of the roll shall present nothing to indent or mar the warp.

These and other objects of the invention will appear mor fully from the accompanying description and drawing and will be particularly pointed out in the claims.

The drawing illustrates a preferred embodiment of the invention.

In the drawing: Fig. 1 is a view in side elevation and partially in central longitudinal cross section of a preferred form of the compressor roll with portions of the heads of a warp beam indicated atthe ends thereof;

Figs. 2 and 3 are details in cross section taken on the line 2-2 of Fig. 1 and illustrating two :tions of a pin and co-operating bayonet slot forming preferred elements of the compressor roll.

Since broadly considered the function and operation of a warp compressor roll is well known and familiar to thoseskilled in the art, it will only be necessary here to describe the construction with which this invention is particularly concerned, it being understood that the roll illustrated will be made of the usual materials employed in such devices.

A warp beam comprises a central shaft and is provided at each end with disk-like heads indicated fragmentarily at In in Fig. 1.

A preferred embodiment of the invention is illustrated in the drawing. Two important features of the invention are, first, that the compressor roll is constructed so that it may readily be adjusted to any required length of warp beam, and, second, that it is constructed so that it will automatically elongate upon a slight relative rotation of its sections to maintain its ends in contact with the inner surfaces of the beam heads and thus be in engagement with the entire width of the warp mass during the beaming operation. The first feature is important because it enables a single apparatus to be employed withany length of warp beam and the second feature is important because it insures that the pressure applied to the warp mass during the beaming operation shall extend over the entire width of the warp mass and thus insure uniformity throughout the entire warp mass and that there shall be no indentation or marring of the warp 'when extension takes place.

"In the preferred construction illustrated the compressor roll is a hollow cylinder and presents two main sections II and I2 having co-operating end elements. In this case the end of the section I l is shouldered at 13 oppositely t0 the shouldered end I4 of the main section I2 so that these ends when brought. together co-operate and fit smoothly. An auxiliary section I5 is provided having end elements, in this case shouldered portions, to co-operate with the end elements of the main sections when interposed between the main sections, and in Fig. 1 this auxiliary'section is illustrated as thus interposed. The'auxiliary section l5 may be of any desired length or more thanone may be employed. Thus it will be seen that by interposing an auxiliary section the compressor roll may be given any required length. Suitable means are provided for clamping together the two main'sections or for clamping the two main sections and the interposed auxiliary section together. In theconstruction illustrated spiders l6 and I! are mounted in and secured by rivets I8 to the main'section II and a spider I9 is similarly mounted in and secured to the main section l3. A bolt having a threaded portion 20 is journaled at its shank 2! in the spiders l6 and I1 and held against inward movement by the head 23. A co-operating nut is formed in or secured to the spider i9. Thus by turning the bolt in the nut the main sections of the compressor rollmay be clamped together or the main sections with the interposed auxiliary section may be clamped together. In the preferred construction the threaded portions of the bolt and nut are complementally mutilated to enable the bolt to he slid through the nut and then by partial rotation brought to clamping position. This enables the sections of the compressor roll to be quickly and firmly clamped together. For this purpose the nut comprises a cylindrical portion 23 of the spider 19 with a section 24 pivoted at 25 and with this section only provided with teeth 26, while the teeth of the bolt are omitted in a sector of the same width as the teeth 26. In

Fig. 3 the bolt is shown with the toothed portion 20 positioned with the mutilated sector opposite the teeth 26 of the nut, thus enabling the bolt to be slid through the nut, while in Fig. 2 the bolt is shown with its toothed sector engaging the teeth of the nut to bring the parts into clamping 7 position.

In the second feature of the compressor roll the hollow cylinder is formed to present two castellated complementary interengaging sections and at the right hand end of Fig. 1 the main secas 30, and extends through and telescopes in a bearing 33 in the other spider, as 3|, and a helical spring 34 on the stud 32 acts yieldingly to separate the castellated sections and thus elongate the cylinder. In Fig. 1 the castellated sections are shown closed but when the spring is free to act the cylinder will be extended as indicated in dotted lines to press against the face of the beam head ID.

A sleeve 35 interiorly telescopes both castellated sections and is secured to one of them, in this case by the rivet 36, to the outer section. A pin 3'! is mounted in the section free from the sleeve, in this case the inner section, and extends into a bayonet slot 38 in the sleeve 35. The pin and bayonet slot co-operate so that when the sec- 'tions are in contracted position the parts are in -the position shown in Fig. 5. In this position the compressor roll is brought between the beam heads but when the beaming operation starts and the compressor roll rotates the spaces 29 permit slight relative rotation of the castellated sections, the pin 31 is released from the notch of the bayonet slot and the spring 34 then acts to elongate the compressor roll and cause its ends to engage the faces of the beam heads. The invention thus presents a very simple and efficient compressor roll enabling a single roll to take care of any length of warp beam, and in suring the application of the required pressure to the entire Warp mass between the beam heads. f This application is a division of applicants ap-v plication Ser. No. 490,252 filed June 10, 1943, now Patent No. 2,337,129 dated December 21, 1943.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

l. A compressor roll for engaging and compressing the warp as it is wound on a beam having heads at each end which comprises a hollow cylinder presenting two main sections having complementary end elements, an auxiliary section having end elements to co-operate with those of the main sections when interposed between the main sections, and means located within the cylinder acting either to clamp together the two main sections: or the two main sections and the interposed auxiliary section.

2. A compressor roll having the construction and operation defined in claim 1 in which one of said main sections presents two castellated complementary interengaging sections together with a resilient means within the said main section acting to elongate the said main section thus to enable the said compressor roll to be adjusted to beams of different lengths and in each case to maintain its ends in contact with the inner surfaces of the beam heads and thus the compressor roll in engagement with the entire width of the warp mass during the beaming operation.

3. A compressor roll for engagin and comj pressing Warp as it is wound on a beam having heads at each end which comprises a hollow cylinder presenting two castellated complementary interengaging sections, a spider within and secured to each section, a sleeve interiorly telescoping both sections and secured to one, resilient means acting between and against the spiders to elongate the cylinder, a pin in the section free from the sleeve, and a co-operating bayonet slot in the sleeve acting to hold the sections in contracted position and to release the sections for elongating movement upon a slight relative rotation.

4'.
