FIBER-SEPABATING MACHINE.

Application filed November 23, 1922.

To (HZ 207mm may concern:

Be it known that we Earner D. VVALEN, of Vatertown, in the county of Middlesex and State of Massachusetts, and ARTHUR H. Reasons, of Gloucester, in the county of Essex, in said State, have invented a new and useful Improvement in Fiber-Separating Machines, of which the following is a specification.

Our invention relates to means for enabling one to determine the average lengths of fibers in a lap. While heretofore there has been an attempt to accomplish this by machines which will lay the fibers according to their lengths on a velvet band so that the lap is separated into fibers of different lengths, such machines have not proved satisfactory because they do not lay the fibers straight and in such a manner that 2 they may be accurately measured individually. y

We have found the machine below described useful for the purpose of laying out fibers for measurement in that the lap is fed regularly to a separating mechanism which draws out the fibers, brushes them straight andlays them in such position that they are measurable and the general or average length of the fibers in a particular lap determined and hence the character of the lap determined.

The invention will be understood by reference to the drawings in which it is shown in its preferred form.

Figure 1 is a plan, 7

Fig. 2 a longitudinal section,

Fig. 3 a side elevation, and

Figs. at and 5 sections on lines 44:, 55 of Fig. 2.

1 is a table on which the various parts are mounted. On standards 2, 2 is carried a shaft 3 by which power is applied to the machine the shaft for this purpose carrying at one end a bevel gear 4 meshing with a similar gearo on the end of a countershaft 6. This shaft 6 is mounted in bearings 7 and 8 suitably supported from the table and carries at its further end a bevel gear 9 meshing with a similar gear 10 on stud 11 mounted on a vertical support or wall 121 carrying one side 12 of a frame 12, 13. the

wall being mounted on the table 1. f 131 is a bottom'piece connecting said sides 12 and 13 of the frame. 1 1, 15, 16 and 17 are rolls each mounted on its own shaft which on the shaft .of roll 171.

Serial No. 602,910.

is. carried between the sides 12 and 13 of the frame. Beneath each of these rolls is a feed roll 141 151, 161 and 171, each mounted on its own shaft and also carried between the sides 12 and 13 of the frame. The shaft carrying the roll 1 11 has at one end a ratchet 18 operated by a pawl 19 carried on the end of a connecting plate 20 mounted on eccentric 21 on the shaft of roll 171. Power is applied tov this shaft by means of a gear 22 on stud 11 mounted to turn with gear 10 and meshing with a gear 23 on a shaft 24, also mounted on the frame. The shaft 2 1 also carries a smaller gear 25 in mesh with a gear 26 on shaft 27. The shaft 27 also carries a gear 28 which meshes with an idler 281 meshing with a gear 29 The shaft of roll 161 also carries a gear 30 in mesh with an idler 31 which is also in mesh with the gear 29 so that the rolls 161 and 171 are rotated in the same direction. The shaft of roll 1 11 carries a gear 32 in mesh with an idler 33 which is in mesh with a gear 341 on the shaft of roll 15 1.

It will be seen that by this means the rotation of the shaft 3 acting through the shaft 6 will give a motion to the gear 26 and its shaft 27 and by means of the gear 28 to the gear 29. on shaft of roll 171 and through it to the roll 161 by means of the idler 31.

Also the rotation of the shaft 171 turning the eccentric21 will give an intermittent motion to the ratchet 18 and its shaft so that the roll 141 will be given an intermittent motion and will impart a similar motion to the roll 151.

The rolls 14, 15, 16 and 17 each are mounted in bearings 35 which slide approximately vertically in ways mounted in the sides 12 and 13 of the frame so that they may conform to the thickness of fiber passing over the feed rolls. These sliding bearings are elongated upwards and carry at their upper ends weights 36 of such character that the rolls 14 15, 16 and 17 will rest upon the fiber causing it to contact with the rolls 1 11, 151. 161 and 171 so that they will be properly fed through the machine.

The shaft 27 also carries a roll 37 which serves as a feed roll to feed the fibers after they come from the separating mechanism to the velvet band by which they are carried away. To keep them in proper contact with this roll we provide a top roll 38 mount ed in bearings 39 which slide vertically in guides 40 in walls 121, 132 which bearings may be adjusted as to pressure'by means of a screw 41 which passes down through threaded blocks 4-2 mounted on top of the walls 121. 132.

To cause the travel of the endless velvet band 44 the shaft 3 carries roll around which the velvet band passes. From the under side of the roll 43 the band 44 passes over a tension device comprising a rest 48 hinged at one end as at 49 to the table 1 and supported at the other end by a leaf spring 50 mounted on the table 1. By this means proper tension may be given to the band.

From the rest 48 the band passes under guide rolls 4?. 46 and 45 and under and apa nst the driven roll 37 and from then over the table'451 to roll 43. The table 451 provides fiat level surface over which the band 44 runs, thus affording a convenient place for inspecting the fibers. This band may be made of velvet or other like material of bru shlike character.

In the operation of the machine, the lap is fed to the rolls 14, 141 which have an intermittent motion and impart intermittent motion to the rolls 15, 151. The rolls 14, 141 pull outtufts of fibers from the supply which may be fed thereto in any convenient way and. feed the tufts to the rolls 15, 151 which are driven at a slightly higher speed than rolls 14, 141, and draw the fibers out more or less from the tuft held by the rolls 14, 141. These fibers are fed intermittently to the constantly-rotating; rolls 16, 161, and from thence are fed to the rolls 17 l'il'which are also constantly rotating and at a speed slightly greater than the rolls 16, 161. The rolls 17, 171 feed the fibers between the rolls 37 and 38 to a position where they are seized by the velvet band 44 which moves at a faster speed so that it brushes the fibers straight while the tuft is still more or less held by. rolls 17, 171, and carries them'over the table 451 where they may be inspected.

The desired (littering speed of the several feed rolls may be secured by using gears of different diameters in a way well known. The rest 48 should have a rough surface over which the surface of the velvet carryingthe fibers should be drawn so that the velvet may be cleaned of its fibers.

This embodiment of our invention is simple to construct and operate. It draws and presents the vfibersfor inspection in such away as to enable the inspector to determine the character of the cotton or other fibrous marinated consideration.

The invention a be otherwise embodied as will be clear to one skilled "in the art. It embodies means for withdrawing fibers from the lap intermittently in such a way that the tufts drawn therefrom are fed to a brushing mechanism to straighten them and are then laid out for inspection.
