v ALEXANDER MCGAUSLAND, 0F PROVIDENCE, RHODE ISLAND.

PAPER-COP TUBES.

Specification of Letters Patent No. 17,746, dated July '7, 1857.

To all whom it may concern.'

Be it known that I, ALEXANDER Mc- CAUsLAND, of Providence, in the county of Providence and State of Rhode Island, have invented a new and improved mode for the construction of the machines known as Paper cop-tubes, used on mule-spindles in cotton-spinning and u on s indles shaped like mule-spindles, and do ereby declare that the following is a full, clear, and exact description of the construction and operation of the same.

The mode of construction of my tube is as follows: Cut a strip of paper into the shape of the drawing hereto annexed (marked A), and which is hereby made a part of this specification, the same varying 1n length as t e size of the tubes may require, and having one of its edges out straight and the other edge cut straight for about two (2) inches from the base or large end of the strip, and being from that point cut ta eringly until it comes to a point at the ot er end of the strip with the opposite straight edge. The length of the stri may vary from ten (10) to twelve (12) inc es, more or less, according to the required size of the tube to be constructed. The tube may be made from any kind of paper as may be desired, although brown Manila paper is the kind most generally used. In order to complete the construction of the tubes as improved by me, the strip of paper is to be moistened with aste at one or its sides, then the base or iOarger end ofthe strip is wound first by hand once round a spindle and the spindle is then carefully turned until the whole is wound up, 4the winding being made tight enough to cause the papers to adhere through its whole extent.

By this process the tube is produced shaped in the form of a truncated cone, and being about six (6) times more or less thicker at the base or larger end than at the top; and the bore remains the same size throughout.

The mode ofthe practical operation of this tube upon spindles is recisely similar to that of the old form of tile paper cop tubes, upon which they are an improvement.

The improvement which results from my invention in the working of these tubes is as follows: Whereas in the course of the working of the old tubes it is customary to use them as long as they will last, and owing to their construction they are not calculated -for endurance, because as the tubes are the same size at both ends, and thinly made, they are always split by being used a few times on the mule or shuttle spindle, and in using the tubes afterward the split or torn parts prevent the yarn from running off freely on account of the adhesion of the thread or yarn, as the case may be, to the split or torn portions of the tube, consequently both tube and yarn are thrown away as waste.

Now, by my improvement it is effected that, owing to the increased thickness ofthe `base or lar er end of the tube, which is first put upon t e spindle, from necessity, on account of the tapering shape of the tube, it is impossible to split them by ordinary use; and, owing to the tapering shape of the tube, as described above, the yarn will in all cases run o it much more easily than it does off of the original ones, thereby saving immense waste, both in the amount of yarn and thread now thrown away and in the number of tubes themselves now necessarily used.

What I claim as my invention, and desire to secure by Letters Patent, is-

The paper cop tube made of a'strip of paper of the form represented in the diagram A in the manner described, whereby greater strength is given to the base of the tube, while the desired conical form is at the same time attained.
