PAPER TWINE FOR USE UPON GRAIN-BINDING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 451,773, dated May 5, 1891. Application filed October 28, 1889. Serial No. 328,386. (Specimens) T all whom, it may concern:

Be it known that I, GEORGE L. RICE, of Ohicago, in the county of Cook and State of Illinois, have invented an Improved Paper Twine for Use upon Grain-Binding Machinery, of

which the following is a description, reference being had to the accompanying drawings.

The object of my invention is to produce a twine from paper of suitable length, thickness, and flexibility for use upon automatic grainbinding and other kindred machinery.

It consists of a central core made from a strip of paper of suitable width twisted into a twine and having a covering made from a I 5 similar strip of paper, which is twisted around the said core.

Figure 1 is a perspective view of such twine partially made. Fig. 2 is a perspective view of the twine in its last stages of manufacture.

Fig. 3 is an enlarged section of the completed twine.

A is the strip of paper which forms the central core. I preferably form it first into a tube, as at a, commencing by turning or fold- 2 5 ing one edge inward, and then twist it, as at a, forming at that place a collapsed tube closely twisted.

B is the strip of paper, of suitable width and thickness,which forms the covering of the twine. I preferably form this strip also into a tube, through which the core runs, and twist it in the same manner as above described.

The twine thus formed is superior to a twine made from one strip of paper having the aggregate width of the two strips above described, because the tubes at a and b, having thinner walls, collapse more easily and are capable of being twisted more closely. The result is that such a twine has greater flexibility and a smaller diameter than if formed in any other manner. It is neither necessary nor possible that the twine should always assume exactly the shape as shown in Fig. 3, because any slight irregularity in the paper will cause the flutings consequent to the collapsing of the walls to vary in number.

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

1. As a new article of manufacture,a twine consisting of a central core of papp g twine and an outer covering formed from a strip of paper, the two twisted together with one in side the other, substantially as and for the purpose described.

2. A twine consisting of a central core and its covering twisted together, the core consisting of a twisted tube formed from a paper strip, and the covering consisting of a paper strip applied in tubular form around the core.
