This invention relates to fiber spinning apparatus and to a fiber spinning method. The invention is particularly applicable and useful. in connection with the spinning of hair into a twisted rope structure.

It has been the practice for many years to form. hair, such as hog, cattle, and other hair, etc., by hand into long strands, to twist the strands to form tight coils, and then to subject the coiled material while secured in coiled form to certain treating operations which give the hair a curled or twisted set. The process is laborious, expensive, and requires highly skilled employees. Even with a high degree of skill. the twisted body is often dropped or broken and the entire spinning job has to be redone.

An object of the present invention is to provide a new means and method for performing the spinning operation so that greater accuracy can be obtained and a more uniform product produced. A further object is to provide means for spinning the product with a high rate of output and with a better quality product as regards the twisting or set give to the hair fiber. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated in connection with specific apparatus shown in the accompanying drawings, in which- Figure 1 is a perspective view of apparatus embodying our invention; Fig. 2, an enlarged side view of a portion of the rotatable hopper structure; Fig. 3, a front view in elevation of a portion of the hopper structure and the drive means therefor; Fig. i, a side view in elevation of the fiber in the process of being formed into a fiber strand and then being coiled; Fig. 5, a top plan view, a portion of the apparatus being broken away to show a belt drive mechanism in section; and Fig. 6, a perspective view of the coiling device employed.

.321 the illustration given, it designates a bus having a tubular collar receiving a standard ii. The standard it carries near its bottom a collar (42 on which is mounted a bracket [13 supporting the motor iii.

The collar it also supports a bearing plate it in which is rotatably mounted a drive shaft it. Mounted upon plate I! '5 also is a supporting member it on which is rotatably mounted a. take-off wheel it. The motor it drives shaft it by means of the belt it which engages a pulley on the motor shaft and pulley it on the drive shaft.

The standard it is provided with a second fixed collar 22 provided with a plate 23.. The plate 23 11]., assign pany, Chicago, Ill., a

provides a bearing for the drive shaft I6 and is equipped with an outwardly-extending bracket 24. A pivoted arm 25 provides a bearing for the pulley 26, and a screw handle 21 provides a means for adjustably moving the support for the pulley. A coiling tube 28 provided with a pulley 29 is rotatably mounted in a sleeve bearing 3@ aflixed to the support plate 23. The pulley 26 is carried by a shaft provided with another pulley t2, and the latter pulley is driven by a belt 33 engaging a pulley carried by the drive shaft 86. Thus the drive shaft l6 drives pulley 32 and thereby pulley 2% while pulley 285, in turn, drives through belt 36 the pulley 29.

Above collar 22 on standard 5 i is a top collar 3 provided with a laterally-extending plate :36. Upon plate 35 is mounted by suitable bearings, rotatable mechanism for supporting a hopper tO-v gether with drive means for the rotatable structure. The plate 35 is preferably formed irategrally with a bearing casing 35, as shown more clearly in Fig 2. Within the bearing casing 36 is mounted a rotatable tube 3? having an integral flange 33 resting upon the bearing 39. The tube 3! is provided at its upper side with a rotatable pulley to and at its lower end with a fixed pulley (ll. Fixed upon the pulley St is a gear 232. Above the gear at and fixed upon tube 3i is a flange 38. The flange 43 secured to the shaft ii is secured by screws or other means within the bottom wall at of the rotatable hopper 15,

The rotatable hopper 85 may be of any suitable construction and formed of any suitable materials. Its purpose is to receive fibers and to feed them. downwardly and inwardly to form a strand, the strand being twisted to provide a ropelike body at the point of exit from the hopper. In the illustration given. the hopper comprises a frame 36, somewhat V-shaped in contour and upon which are mounted the upper rollers ll and the lower rollers 68. The rollers 68 carry belts 439 which feed the hair inwardly toward a central point. The shafts or rollers t5 are preferably provided with worm gears 58 driven by the vertical worms 58. The worm 5i is mounted upon a shaft 52 fixed at its bottom to a gear 53 mounted on the shaft. The shaft 52 is rotatably mounted within the bottom wall (it of the hopper, and the gear 53 meshes with the drive gear 42 of tube 37.

The hopper, in addition to having the inwardlyinclined belts as for drawing the fibers downwarclly toward a central poin has inwardlyturned side walls 55 which direct the fiber toward a central point in, the hopper. The side walls or slide plates 55 are slotted to receive the two narrow spring-loaded wheels 58, shown best in Figs. 1, 2 and 3. The wheels 56 are rim-driven through friction with the feed belts 49, as shown best in Figs. 2 and 5. The wheels are guided between the spaced metal straps 51 which are supported by springs 58, as shown more clearly in Figs. 1 and 2. It will be understood that the wheels 56 may be driven by any other suitable means.

Any suitable means for driving the tube 31 may be employed. In the illustration iven, the drive shaft [6 is provided at its top with a pulley 59 and spaced therebelow with a second pulley 60. A change speed pulley BI is mounted on an auxiliary shaft 62. The change speed pulley BI is provided with a shiftable inner pulley member 63 which may be moved laterally to change the speed ratio between the pulley 59 and the pulley 4G rotatable on shaft 31. Since this structure is well known. a detailed description is believed unnecessary. The shaft Bi is mounted upon a pivotally-supported arm 64, and the arm 64 is adjustable by means of the handle-equipped screw member 65, as shown more clearly in Figs. 3 and 5. Pulleys 4| and 60 are connected by belt 66.

The coiling structure may be ofany suitable form or construction. In the illustration shown best in Fig. 6, we provide a horn 61 secured to one side of the pulley 29 and extending inwardly into alignment with the hollow shaft 28. The horn 61 is provided with a downwardly-extending tip or projection 68. Above the tip 68 is an inclined vane 69 which aids in the removal of the coiled rope as it is being formed upon the born 61.

Any suitable means for feeding the hair or other fibers to the hopper may be employed. In the illustration given, we provide simply an inlet chute 10. It will be understood that the chute or delivery pipe may lead from any suitable device from which fibers are delivered in separated condition for feeding to the machine. For example, if desired, the hair may be supplied to a fiber device equipped with card and brush rolls of well known construction which will deliver properly combed hair in separated condition for feeding to the spinning machine. The hair will then be guided down a pipe or chute to the hopper. It is important that the hair be delivered in separated condition and not in clumps to the rotating hopper.

Operation In the operation of the machine, the separated fibers are delivered at a desired rate through pipe 10 to the rotating hopper 45. The hopper, with its arrangement of two belts and the two gathering plates or sides, forms in effect an equal-sided pyramid with the apex downward. The belts are driven by the main drive shaft through the pulley 59, intermediate pulley Bi, and the gear-equipped pulley 4B. The worms are driven by the gears 53 and drive gear 42. The-drive gear 42 drives the shaft gears 53 by virtue of relative rotation of the drive gear with respect to the rotation of the frame carrying the feed belts.

The feed hopper is driven by tube 31 equipped with the pulley ll. It will be understood that the feed hopper may be rotated at various speeds depending upon the material being fed to it and the diameter of the rope to be made. For example, the feed hopper may be rotated at 500 revolutions per minute or more at a strand rate of to per revolution depending on the diameter of the rope made.

The hair. fed downwardly by the belts and compacted through the action of the side plates and. further by the rimmed ribbon wheels 58,

is formed by the twisting action of the hopper into a tightly compacted strand. This strand passes through the rotating coil means 61 and is thereupon coiled tightly into the form shown in Fig. 4-a coiled rope.

The speed of rotation of the hopper which in a typical case might be 500 R. P. M., imparts not only the total twist to form the fibers into a strand, but also provides the additional revolutions to form the strand into a coiled rope. The allocation of the twisting action between strand formation and coil formation is governed, however, by the speed of rotation of coiling means 61; that, is, the coiling means controls to what degree the twisting action is dissipated in coiling the strand as a whole rather than in twisting the individual fibers into the strand.

A familiar analogy to this division of twist between strand and coil is the behavior of a rubber band when it is extensively twisted. It will be recalled that after it has been twisted a large number of times, such a rubber band exhibits a tendency to form coils rather than to tighten further the twisting of the individual strand. That action occurs with the present invention, and the number of coils formed per unit length in the rope which is the end product of the operation of our machine is governed by the speed of rotation of coiling member 67, it being assumed that the rate at. which the rope is passed under the guide roller I8 is constant. Thus, while the coiling member 61 does not, in the strict sense, accomplish any twisting action in its own right, it does play an important role in governing the characteristics of the rope produced by our in chine. Normally a very tightly coiled rope is desirable, and, in that event, it is desirable to rotate member 61 at a fairly substantial rate of speed, such as 40 to 60 R. P. M.

After the rope has been formed by our machine and has passed under guide roller l8, it may be carried to any desired destination; usually it will be wound on a spool or spindle. It will of course be understood that the means employed to carry the rope onward from guide roller l8 must not place the rope under heavy tension, since proper formation of a coiled rope by the coiling member 61 requires that the tension 'on the strand below member 61 be less than that existing above it.

Details of operation may vary according to the type of hair being fed to the machine; this may affect the optimum speed of rotation of both the hopper and the coiling member.

In the operation of our machine, we have found that the vane and horn of the coiling means provide uniform tension on the twisted hair strand above. If desired, supplemental tension-maintaining means, such as a pair of feed pulleys mounted on the top of the coiling means and rotating with it, may be employed.

While the apparatus illustrated shows mechanism for changing the relative speed of the various driven parts, it will be understood that any suitable devices for this purpose may be employed so that the speeds of the various operative devices may be widely varied to meet the requirements of different types of fibers, etc.

Heretofore in hand spinning, it has been considered impossible to spin uniform rope from hog hair. In order to form such a rope, it has been necessary to add to the hog hair at least 10% of other hair, such as cattle hair. The new machine permits the spinning of hog hair, while at the same time producing a. much more uniform ropeand one of higher grade. The apparatus permits" the spinning of all grades of hair from 100% hog hair to 100% cattle or horse mane, together with any desired proportions of the foregoing fibers or similar fibers.

While in the foregoing specification, we have described the apparatus and steps of the process in considerable detail for the purpose of illustrating one embodiment of the invention, it will be understood that such details may be varied widely by those skilled in the art without departing from the spirit of our invention.
