To all whom t may concern.'

Be it known that I, GEORGE L. "RICE, a

citizen of the United States, residing at Chicago, in the county of Cook and State o'f Illinois, have invented certain new and.

useful Improvements in Machines and Methods for vMak/ing Combination Paper-Fiber Twine, o'f which the following is a full, clear, and exact specification. .l

This application is a division of application Serial No. 200,896, filed November 8, 1917, and the inventionforming the subject matter Ot this application relates to ma'- chines and methods for making combination .paper-fiber twine. y

I am well aware lthat therel are many twines of this general type on the market which are lmade by covering a fiber center with paper, but in all cases the liber center is spun into a yarn previous to covering the same with the paper. In other words, the spinning of the fiber center and the combining of the liber with the paper are two separate and distinct operations. When the spun center and paper are .being put together in this manner the tension' on each is separately regulated, 'and the number of twists in'the fiber center is entirely independent of and usually differs from the number of twists in the paper covering or sheath. The twine made in this manner is defective` since there is no intertwisting or interlocking of theiiber and the paper, and the paper covering is, therefore, easily stripped 'from' the fiber center. Moreover,

the difference in the number 'of twists per unit of length. in the'fiber center and paperv cover, and the fact that l.the fibencenter,

having previously been twisted into a twine, receives additional twist when the paper 'cover is'applied, results a twine which 'isi stiff and kinky, and unsuitable when employed'in such manner that it must be fed through guidingeyes or employed in binding and 'knotting machines.

The object of myln'vention is to provide a stron and flexible' 'paper ber twine havcient weather proofing and insect proong qualities to meet the ordinary conditions, and more' `particularly the conditions encountered in the use of suchtwine 1n harvest1ngmach1nerya nd moreover to Fig. 2 vshows an enlarged V detail provide a twine which will notikink and in I feeding the paper and non-twisted fiber,`

means for folding the paper about the ber, preferably in such a manner that the paper will entirely cover the ber'and that portions o'f the ber will be disposed in longitudinal creases in the paper which may be formed by the paper feeding and folding means, and means for spinning or twisting the paper and ber together. p In a more specific form the machine may embody the elements enumerated below', al-

though it should be distinctly understood that it is not essential that all of these elements be present for the successful operation of the machine.

The machine in its more specific form, then, embodies means for simultaneously drawing and `feeding untwisted fiber and a ribbon of paper, means for slightly condensing the ber into a loose coreV and for forming \the paper into a tube around this core, means for` crushing or crimping the paper Onto'the loose ber core 'in such a manner that some of the'bers of the loose core are disposed in the longitudinal seams formed by the crushing means, and means 'for simultaneously twisting theuntwisted ber and crimped paper together to form the combination paper and fiber twine in which the paper covering is interlocked and intertwistedwith the fiber core.

In the accompanying drawings Iv have` f illustrated one embodiment of my'invention, Vand in these vdrawings,--

Fig. 5 is a front'elevation of the construction shown in Fig. 4;

Fig. 6 illustrates one step in the method of forming the twine; and

Fig. 7 is a perspective showing the twine formed by my improved method and machine.

The usual type ofhorizontal flierA spinning machine is employed, and this machine embodies a supporti-ng frame '10, the usual Hier frame 11, bobbin 12, and capstan pulleys 13. The paper is carried on a reel v14, supported by the main frame, and passes over an idler pulley 15 and a moistening roller 16, which are supported by the supply tank 17 for the molstening liquor. The roller 16 is positively driven by means gf the gearing 18, 1-9 and 20, the gear 20 ein carrigesl a sprocket 22, which meshes with the feeding mechanism for the sliver. This feeding mechanism for the fiber comprises the usual gill bars 23 'and gill pins 24, driven in the usual manner. By means of this sprocket 22 and the intermediate gearing which is supported by the tank 17, I have provided a positive drive for the moistening roller 16, and in this manner the amount of moisture fed to the paper strip 2'5 can be positively controlled. The liquid Fin the tank 17 may consist simply of water, Ior an emulsion of water and oil, preferably animal or mineral oil, with which the paper may be treated to make it weather proof and insect proof. It is, however, not absolutely essential thatV the paper be treated with oil since the fiber is always treated with oil, and the intertwisting of the fiber and paper forces and squeezes the oil outwardly into the paper.

The feeding and drawing :mechanism vfor the ribbon of paper and the sliver is substantially the/'same asV that shown in lmy Patent, No. 1,217,067, granted February 20,

1917, and consists of a large feeding rollerv 26 mounted above two

small feeding rollers

27 and 28, the

rollers

27 and 28 being positively driven by suitable gearing mechanism. The shaft for the roller 26 is journaled in a box 29, slidable in a supporting bracket 30, pivoted at 31 to a fixed part of the frame. I- have provided suitable means by which the roller 26 may be lifted out of. contact with the

rollers

27 and 28, and this means comprises a link 32 suitably pivoted to a handle or lever 33, which in turn is pivoted at 34- to a fixed part' of the frame. iWhen it is desired to obtain access to the feeding rollers the arm 33 is lifted and'sw'ung about the pivot 34 until the stop 35- contacts with a portion 36V of the main frame.,r thereby raising the roller 26.

The ribbon 25 of paper after leaving the moisteningroller 16 passes'around an idler 3-7 carried by the main frame, and through mounted on a pintle 21 which also densing .the sliver.

that the flat paper ribbon and the nontwisted sliver are positively and simultaneously fed through the machine, the

rollers

26, 27 and 28 having the same drawing action described and claimed in my Patent No. 1,217,067 above referred to. By means of this simultaneous feeding the tension on the paper andthe sliver is maintained uniform, and this is a distinct advantage in that it avoids any tendency in the completed paper twine to break through unequal strains. y After passing through the

feeding rollers

26, 27 and 28 the paper ribbon and the loose ber core are passed through a former 40, the main body portion o f this former having the shape of a hollow cone. This conical body portion is provided with laterally projecting lugs 41, having slots 42, which are provided with suitable securing means for clamping the former to the frame of the spinning machine. On the insideof this conical body there is secured a guide 43 for the non-twisted fiber, this guide consisting of a grooved or concave member, the side walls of which converge vtoward the front of the cone for the purpose of cou- From an inspection of Fig. 2 it will be seen that the front end of this member 42 is disposed substantially ina line with the contacting surfacesv of the feed rollers 26. 27 `and 28, so that the sliver is not defiected materially out of the plane in which it is fed to the former. The paper after it leaves the feedrollers, as is clearly shown in Fig. 2, vis positively fed into the former and contacts with the upper wall of the conical body portion, and this wall forms the flat ribbon into a tube, as illustrated in Fig. 6. This'tube is wrappedV around the loose vber core and is crimped into longitudinal folds or creases 46, and the tube and the core are simultaneously fed forward to aV Crusher 44. and nipper 45, similar to the correspondmg members shown in my patent above referred to. By means of the Crusher and nipper the tube is further crimped and fiber nor the paper is twisted separately,

and that substantially no twisting action takes place until the fiber and paper have 45, when the two elements are simultaneously twisted together, and in this way a twine is provided in which the two elements are simultaneously twisted together, thereby forming a twine in which the two elements making up the same have the same number of twists perunit of length. By .means of this simultaneous feeding the tension on the paper and ber is maintained uniform, and this is a distinct advantage in that it avoids `any tendency in the completed twineto break through unequalv strains, and also aids vin interlocking the inner ber core and paper covering together. Moreover, `by twisting the twoelements together simultaneously, forming a unitary structure, I have also succeeded in roducing a. twine,

the elements 4of which w1llI not be separated from each other by. stripping even when the twine is subjected to severe and unusualuse.
